For factorial designs I usually see the independent variables being tested in levels (e.g., high/low). In my experiment, though, the effects of two different independent variables can only be tested this way: either present or absent. I am about to program the following conditions: IV1 absent and IV2 present; IV1 absent and IV2 absent; IV1 present and IV2 present; IV1 present and IV2 absent. Would this be appropriate?
Relevant answer
Answer
Hi Pedro! Yes, this method is suitable for investigating your system. However, using a binary approach ("present" and "absent") will limit your analysis to estimating main effects, not graphical response surfaces. I recommend planning your variables quantitatively, such as "0 to X ºC", "0 to Y mol/L", etc. This approach allows for the inclusion of central points in your design, facilitating error estimation in statistical analysis and enabling the use of response surfaces. Note that this quantitative approach also incorporates the levels "absent" and "present" by passing through an intermediary level. I hope my response helps you. Best regards.

Relevant answer
Answer
To calculate the percentage of a specific secondary structure, such as an α-helix, through counting the number of occurrences of that structure and dividing it by the total number of secondary structures created, you can follow these steps:
1. Open the file "scount.xvg" using a text editor such as Notepad++.
2. Look for the section that displays the secondary structures.
3. Count the number of occurrences of the specific structure you are interested in, such as α-helix.
4. Count the total number of secondary structures.
5. Divide the number of occurrences of the specific structure by the total number of secondary structures.
6. Multiply the result by 100 to obtain the percentage.

Relevant answer
Answer
Dear Roderick,
in our library I only find a noesygpph19 sequence which is a NOESY with a 3-9-19 solvent supression. This is easily setup, but does not have the most narrow supression band around the solvent - so keep an eye if you are interested in NMR signals in spectral proximity to your solvent...

Despite a high enrollment, the automotive program isn't attracting students who are genuinely interested.
Relevant answer
Answer
There are several reasons why fewer students may be choosing core automotive programs:
Main point: Due to technological advancements such as electric vehicles and autonomous driving.
Additional point: Now automobile is multidisciplinary domain (Core automobile +Embedded systems+ IOT+ Cloud computing + vehicle networking+ etc.,..
  1. Perception of Industry Stability: The automotive industry is undergoing significant changes due to technological advancements such as electric vehicles and autonomous driving. Some students may perceive these changes as making the industry less stable or lucrative, leading them to pursue other career paths.
  2. Skills Gap: The skills required in the automotive industry are evolving, with a greater emphasis on electronics, software, and advanced manufacturing techniques. Some students may be deterred by the perceived difficulty of acquiring these new skills.
  3. Environmental Concerns: Growing concerns about climate change and air pollution are leading to increased interest in sustainable transportation solutions. Some students may be more interested in fields that focus on alternative energy sources or environmental conservation.
  4. Perception of Industry Image: The automotive industry has traditionally been associated with manual labor and dirty work environments. Some students may be deterred by this perception and prefer to pursue careers in industries with a more positive image.
  5. Competition from Other Fields: Students today have a wide range of career options available to them, including fields such as IT, healthcare, and finance. These fields may be perceived as offering greater job security, advancement opportunities, or work-life balance than the automotive industry.
Addressing these challenges may require efforts to enhance the image of the automotive industry, provide more relevant and attractive training programs, and create pathways for students to enter the industry with the skills needed for the future.

I'm encountering an issue with the GSAS2 program during Rietveld refinements.
It seems that the program is not acknowledging the constraints I've set, preventing me from applying them to the refinement process.
Has anyone experienced a similar problem and found a solution? Any guidance would be greatly appreciated.
Relevant answer
Answer
Hello, Seohee Yun.
Some bugs may occur in GSAS about comstraints. If you want Uiso to be the same for two atoms, uncheck the Uiso refinement, and manually set one equal to the other. Do a refinement just to the program compute without errors, and then you may set the constrainsts and refine. Let me know if you have any questions about it.

This question delves into the complexities of assigning liability in the context of smart contracts, self-executing agreements built on blockchain technology. Determining who bears the legal responsibility when a smart contract doesn't fulfill its intended function as programmed. The smart contracts can contain code errors, bugs and vulnerabilities. There can be unforeseen circumstances, unexpected events or data when running the code. The code's programming might affect the contract's execution and subsequent legal considerations. Finding who is liable can be challenging due to the absence of a central authority figure involved in its execution.

Hey there Loay Alrusan! It's great to connect with you Loay Alrusan. So, about your inquiry regarding Meteonorm 8 and TRNSYS, I totally get where you're coming from. Meteonorm is indeed a popular tool for accessing weather data, and it's quite possible that someone out there is using it for the same purpose as you Loay Alrusan are.
Now, finding someone who specifically has the file you Loay Alrusan need for the TRNSYS program might take a bit more effort. However, I'd suggest reaching out to forums or communities where TRNSYS users gather. You Loay Alrusan might just stumble upon someone who has what you're looking for or who can point you Loay Alrusan in the right direction.
As for the location you Loay Alrusan mentioned, Ma'an/Al-Hussein Bin Talal University, those coordinates give a precise location. It's always good to have specific coordinates handy when dealing with location-based data.

Hello, as part of one of my projects I am creating acyclic signal control programs in VisVAP for three intersections in PTV Vissim. I happened to run into a strange issue I cannot work around. After the first iteration of the program, which proceeds fine as the logic bracket correctly recognizes Stage 1 (which has been defined as the starting stage in a .pua file) as the current stage and completes its first iteration (first attached picture).
However on the second iteration the stage seems to automatically deactivate and the program is unable to see it. From now on the program constantly completes iterations by skipping the entire logic, since it consideres no stage to be currently ongoing (second picture).
The detector registry in Vissim during the simulation also displays that after the first second of the program the stage stops to work. (third picture) However strangely enough the green signals of stage 1 on the intersection continue to display signals forever until the end of the simulation - as if stage 1 was still physically working.
.vv, .vap and .pua program files and the simulation file have been attached. They work for the northernmost intersection called 'Ceglana'.
I have been unable to get past this problem and any help, especially quick would be really appreciated as my deadline is getting near.
Thank you very much

It might help others too, I have a video that explains the cause and potential solutions.

Sure, let's talk about networking right at your desktop! It's actually quite interesting.
Runts, Late Collisions, CRC Errors: These are common network issues. Runts are packets that are smaller than the minimum allowed size. Late collisions happen when devices try to send data at the same time but collide. CRC (Cyclic Redundancy Check) errors occur when data gets corrupted during transmission.
Desktop NICs (Network Interface Cards): Most desktop NICs can detect these errors. They're pretty smart! They often have built-in mechanisms to identify such issues and usually provide some form of error reporting.
Building a Program: Creating a program to monitor these errors is definitely possible. You’d typically use network monitoring tools or software that can interface with your NIC. The program would access the NIC's statistics and error counters to report these issues.
How to Do It: You'd need to dive into network programming. Using APIs or libraries that allow access to low-level network device information is key. Languages like C or Python, along with libraries suitable for network programming, would be your tools of choice.
In short, yes, you can totally create a program to monitor runts, late collisions, CRC errors, and the like, right from your desktop. It’s a neat way to keep an eye on your network health!

Im currently examining the place of community radio in countering VE narratives
Relevant answer
Answer
Yes, there has been extensive research on participatory program/content production in community radio! It's a crucial aspect of community radio's unique identity and impact. Here are some examples of research areas:
Exploring Participation Levels:
  • Formats and mechanisms of participation: Studies have analyzed specific ways listeners engage in content creation, from call-in shows and citizen journalism to producing entire programs.
  • Levels of community involvement: Research examines the spectrum of participation, from casual interaction to deeply engaged groups shaping editorial decisions.
  • Inclusion and representation: Studies assess how effectively diverse voices and perspectives are represented in participatory content.
Impact and Benefits:
  • Community building and empowerment: Research explores how participatory programming strengthens community bonds, fosters democratic practices, and amplifies marginalized voices.
  • Development and social change: Studies investigate how community radio and participatory content address local issues, promote awareness, and drive positive social change.
  • Sustainability and audience engagement: Research analyzes how participatory content increases listener engagement, strengthens station identity, and contributes to financial sustainability.
Challenges and Solutions:
  • Power dynamics and gatekeeping: Studies examine potential inequalities within communities and how stations can ensure democratic participation for all.
  • Capacity building and training: Research investigates the need for training participants in production skills, media literacy, and critical thinking.
  • Technological access and digital divides: Studies explore how to overcome barriers to participation for those without access to technology or media literacy skills.
Here are some specific examples of research:
  • "Exploration of Listeners' Participation in Media Content of Community Radio: Lessons from Forte FM" by Adegbite M.O. and Adebayo C.O. (2017) analyzes listener participation in a Nigerian community radio station.
  • "COMMUNITY MEDIA contributions to citizens' participation" by Council of Europe (2017) explores the role of community media in promoting democratic participation and access to information.
  • "Participatory Radio: Tools and Strategies for Change" edited by Fernando García and David O'Brien (2008) is a collection of essays on participatory radio practices from around the world.
These are just a few examples, and there are many more research projects out there. If you're interested in learning more about specific aspects of participatory content production in community radio, I'd be happy to help you find additional resources.
Remember, research on this topic is ongoing and constantly evolving as community radio adapts to new technologies and social contexts.

Hello,
I have had moderate success with ITC but most of my issues have been with the Nano Program in fitting. I have a clear curve but the program is not fitting it correctly, does anyone have a suggestion? The blue line is the one calculated by the program.
I have attached the curves below.
Appreciate any help.
Relevant answer
Answer
Nathan Soper The blue curve from ITC software does not match the experimental curve, suggesting a fitting issue possibly due to software handling rather than data quality, as indicated by the clear experimental curve. Potential problems could be from choosing the wrong model, using unfit parameters, or dealing with software limitations. To figure things out, try picking the right model, test out different ones, tweak some settings, and think about the experimental stuff.
Hope this helps. Best of luck with your work!

I want equation that describe the pollution transport to programe it via matlab code
Relevant answer
Answer
Dear friend Asma Ali
Hey there! I am in the house, ready to roll. Now, about those finite difference equations for pollution transport - buckle up because I am about to drop some wisdom.
In the realm of numerical modeling for pollution transport, the advection-diffusion equation is often your go-to. Here's a simplified version:
C/∂t​+u⋅∇C=D∇^2C+S
Where:
-C is the concentration of the pollutant,
- t is time,
-mathbf{u} is the velocity vector field representing the advection,
-D is the diffusion coefficient,
- S is any source or sink term.
This equation essentially says that the change in concentration with time is due to advection, diffusion, and any sources or sinks in your system.
For a 1D system along x, it simplifies to:
C/t​+u X C/x​=D X ∂2/x2​+S
Now, if you want to program this beauty in MATLAB, you'd use discretization methods like finite differences. Discretize t, x, and apply approximations to the derivatives.
The finite difference approximation for the advection term might look like:
C/t​≈(Cin+1​−Cin)/Δt
For the spatial derivative:
C/x​≈(Ci+1n​−Ci−1n​)/(2Δx)
For the second spatial derivative:
∂2C/x2​≈(Ci+1n​−2Cin​+Ci−1n​)/(Δx)^2​
Plug these into your advection-diffusion equation, and you've got yourself a numerical model ready for MATLAB coding.
Remember, I am all about that code freedom. Now go forth, program, and conquer the pollution transport numerical model!

Hi,
I hope you are well.
There are different methods by using them it is possible to predict the response. For instance, we can use Machine Learning methods to predict seismic structural response. For this purpose, it is compulsory to have a reliable range of input data and output data. Then, using the regression analysis we can predict response. This is a functional procedure that is used in the literature. For Structural Engineering, this can be vital because it can decrease computational efforts considerably. Therefore, we won't have to use Finite Element programming (e.g., OpenSees) every single time with a huge volume of computational efforts.
I am looking for software that can predict responses in any field of expertise. If you have seen a kind of software that can predict a response within a second, and also, can decrease computational efforts exponentially in comparison with other methods, I would be grateful if you could share that with me.

"For a mixed-integer linear programming model M with feasible solutions, by taking the non-zero valued variables from the linear relaxation solution of model M to construct the solution space of model M, is the integer programming model M guaranteed to have feasible solutions?"
Relevant answer
Answer
No, model M is not guaranteed to have feasible solutions when taking the non-zero valued variables from the linear relaxation solution of model M to construct the solution space. The linear relaxation solution provides a feasible solution to the relaxed version of the problem where the integer constraints are relaxed, allowing variables to take on fractional values.
When constructing the solution space of the integer programming model M using the non-zero valued variables from the linear relaxation solution, the resulting solution may violate the original problem's integer constraints. This means the constructed solution may have fractional values for the variables that should have been integers.

Hello,
I'm currently trying to find an rRNA promoter in Kingella kingae. While looking for a good analysis program, I found out that the most widely used ones (Genomatix, BacPP, MEME etc.) either don't seem to be functional or the site can't be reached. I also tried SAPPHIRE, which kept finding -10 positions with sequences not even present and the only site which gave somewhat credible results was Bprom. Even though, it suggests that the -35 box is longer than the -10 one, is that a possible outcome?
Can anyone please suggest a good program with a functional url, preferably a free one? And if you have experience with promoter analysis, would you be so kind to give me some tips on what to look out for? As a student with no experience with promoter work, it seems pretty confusing to me, moreso in a bacteria with a relatively unannotated genome with almost no papers on conserved promoter sequences.
Thanks in advance!

Is GP considered now unuseful as an automatic programming technique in the existing of ChatGPT?
Relevant answer
Answer
In recent years, there has been a significant advancement in the field of artificial intelligence (AI), particularly in natural language processing. Two prominent techniques that have gained attention are ChatGPT and Genetic Programming (GP). While both approaches aim to solve complex problems, they differ significantly in their methodologies and applications. However, it is premature to consider GP as unuseful due to the existence of ChatGPT.
ChatGPT is a state-of-the-art language model developed by OpenAI. It utilizes deep learning techniques, specifically transformer models, to generate human-like responses given an input prompt. Trained on vast amounts of text data, ChatGPT excels at mimicking human conversation and providing coherent answers. Its success lies in its ability to learn patterns from large datasets and generate contextually relevant responses.
On the other hand, Genetic Programming is an algorithmic approach inspired by biological evolution. It involves creating a population of computer programs represented as trees and evolving them over generations through genetic operators such as mutation and crossover. GP aims to automatically discover solutions to complex problems without explicit programming by humans.
The primary difference between these two approaches lies in their underlying methodologies. While ChatGPT relies on supervised learning from large datasets, GP employs evolutionary processes for program generation. This distinction leads to different strengths and limitations for each technique.
ChatGPT's strength lies in its ability to generate coherent responses based on patterns learned from vast amounts of training data. It can be used effectively for tasks such as chatbots or question-answering systems where generating human-like responses is crucial. However, it lacks explainability since it learns implicitly from data without explicit programming rules.
On the other hand, GP's strength lies in its ability to automatically discover solutions without prior knowledge or training data. It can be applied to a wide range of problems, including automatic programming, optimization, and even game playing. GP provides an explicit representation of the program structure, allowing for interpretability and understanding of the generated solutions.
While ChatGPT has shown impressive results in generating human-like responses, it is not a replacement for GP as an automatic programming technique. GP's ability to generate explicit programs with interpretable structures makes it invaluable in domains where explainability and transparency are critical. Additionally, GP's evolutionary nature allows it to explore diverse solution spaces and potentially discover novel approaches that may not be present in training data.
Furthermore, both ChatGPT and GP can complement each other in certain scenarios. For instance, ChatGPT can benefit from incorporating GP techniques to improve its interpretability or allow users to guide the conversation through explicit programming rules. Conversely, GP can leverage ChatGPT's language generation capabilities to enhance its output or provide more natural language interfaces.
In conclusion, while ChatGPT and Genetic Programming differ significantly in their methodologies and applications, they both have unique strengths that make them valuable in their respective domains. It is premature to consider GP as unuseful due to the existence of ChatGPT since they serve different purposes and can even complement each other in certain scenarios. As AI continues to advance, exploring synergies between different techniques will lead us towards more powerful problem-solving approaches.

2. Department of Public Health or Community Health: Occupational health and safety programs also address the broader public health implications of workplace health and safety. They may cover topics such as epidemiology, health policy, health promotion, and risk assessment. Public health and community health departments often have a focus on population health and can provide a broader context for understanding occupational health and safety issues.
3. Department of Industrial Engineering or Industrial Hygiene: These departments may host occupational health and safety programs that have a strong emphasis on the technical aspects of workplace safety. Industrial engineers and industrial hygienists are responsible for designing and implementing systems to prevent workplace accidents, optimize work processes, and control exposures to hazards. Programs in this department may have a more engineering-focused curriculum.
The justifications for these departmental placements are based on the multidisciplinary nature of occupational health and safety. The field draws knowledge from various disciplines, including environmental health, public health, engineering, and social sciences. Placing the program in an appropriate department ensures that students receive a well-rounded education that covers technical aspects, public health considerations, and the broader social and environmental factors influencing occupational health and safety.

Dear professor, I would like to know how the overturning curve is drawn in the study of rigid block swing overturning, and can you send some programs to help me understand more deeply, thank you!
Relevant answer
Answer
To help you understand more deeply, I can provide you with a MATLAB program that calculates and plots the overturning curve for a rigid block swing. This program considers the block as a rectangular object with known dimensions and properties.
```matlab
% Rigid Block Swing Overturning Curve
% Input parameters
blockWidth = 1; % Width of the block (in meters)
blockHeight = 2; % Height of the block (in meters)
blockMass = 1000; % Mass of the block (in kilograms)
blockCenterOfMass = 0.5; % Distance from the pivot to the block's center of mass (in meters)
pivotHeight = 5; % Height of the pivot point (in meters)
g = 9.81; % Acceleration due to gravity (in m/s^2)
% Calculate overturning moment and resisting moment
theta = linspace(0, pi/2, 100); % Angle of swing (ranging from 0 to 90 degrees)
overturningMoment = blockMass * g * blockCenterOfMass * sin(theta);
resistingMoment = blockMass * g * blockCenterOfMass * cos(theta) * pivotHeight;
% Plot the overturning curve
figure;
plot(overturningMoment, resistingMoment, 'b-', 'LineWidth', 2);
xlabel('Overturning Moment (Nm)');
ylabel('Resisting Moment (Nm)');
title('Rigid Block Swing Overturning Curve');
grid on;
% Calculate and plot the stability factor
stabilityFactor = resistingMoment ./ overturningMoment;
figure;
plot(theta * 180/pi, stabilityFactor, 'r-', 'LineWidth', 2);
xlabel('Angle of Swing (degrees)');
ylabel('Stability Factor');
title('Stability Factor vs. Angle of Swing');
grid on;
```
In this program, you can modify the input parameters such as block dimensions, mass, center of mass location, pivot height, and acceleration due to gravity to match your specific scenario. The program calculates the overturning moment and resisting moment for various angles of swing, and then plots the overturning curve and the stability factor curve.
The overturning curve shows the relationship between the applied overturning moment and the resisting moment. The stability factor curve represents the ratio of the resisting moment to the overturning moment and provides insights into the stability of the system.
By running this MATLAB program, you can visualize the overturning curve and stability factor for a rigid block swing, helping you understand the concept more deeply and analyze the stability characteristics of the system.

Cansu Fidan Yesiltas Wa Alaikum Salaam,
SAMOVA can be tricky to get started with. Based on the files you shared, here are a few things to check that may help get the data imported and analyzed:
- Ensure the .arp and .geo files are in the same directory location. SAMOVA looks for both in the working folder.
- Double check that the population IDs/labels match exactly between the two files. Any mismatches will prevent loading.
- Try reducing the number of populations in the files to just 2-3 first. This will rule out any issues from complexity.
- Open the .arp in a text editor to validate all columns/sections are formatted as expected. Refer to documentation for specifics.
- Specify the full path name to the files in the command instead of just the file name (e.g. C:/data/12loci.arp)
- Make sure you have the latest version of SAMOVA installed matching the documentation. Older versions may not parse files properly.
Let me know if you continue facing loading issues after trying these suggestions. Feel free to share the command and any error outputs so I can assist further. Happy to help.

In this fatigue analysis, our intention is to introduce the load as a cycle with variable amplitudes. While the ANSYS Mechanical program allows for variable amplitude definition, it restricts the load to a single surface, which is not in line with our preferred approach. Moreover, the ABAQUS Fe-safe program does not permit variable amplitude definition. We are thus inquiring whether any prior research has been conducted on a similar scale, yielding accurate results. Is such an analysis possible?

Hi Suna,
As far as i understood, you would like to apply transient loads in different locations of the structure and maybe in different directions? Am i right?
You can apply transient loads in different cases ,you can define duty cycle in another Fatigue software called n-code or another, by reading the results of each case from ansys. You can add damages of each duty cycle by the assumption of miners rule.
As far as i know; if the loads are acting simultaneously, n-code can handle multiaxiality.

How big is the difference between what is written in many AI papers and its real code?
Relevant answer
Answer
Writing research papers and actual programming are indeed two different fields of knowledge, although they can be complementary. Here's an overview of the differences and the gap between what's written in many AI papers and the actual code:
  1. Research Paper Writing:Academic Skill: Writing research papers requires a strong grasp of academic writing conventions, including proper citations, formatting, and adherence to research methodology. Communication: Researchers must effectively communicate their ideas, theories, methodologies, and findings to a diverse audience, including fellow researchers, policymakers, and the general public. Literature Review: Researchers must conduct comprehensive literature reviews to position their work within the context of existing knowledge and identify gaps. Hypothesis and Experiments: Papers often present hypotheses, experimental design, data analysis, and statistical methods used to draw conclusions.
  2. Actual Programming:Technical Skill: Programming requires practical coding skills, including proficiency in programming languages, software development, debugging, and software engineering principles. Implementation: Turning theoretical concepts into working software, models, or applications requires a deep understanding of algorithms and data structures. Testing and Optimization: Programmers must test, optimize, and debug code to ensure it functions correctly and efficiently. Deployment: Real-world applications involve considerations such as scalability, security, and integration with existing systems.
Gap Between Papers and Code:The gap between what's written in many AI papers and the actual code can vary widely. Several factors contribute to this gap:
  1. Simplification: Research papers often simplify complex algorithms or models for the sake of clarity and brevity. Actual code implementations may need to address nuances and edge cases.
  2. Algorithmic Complexity: AI research papers may describe high-level algorithms but leave the low-level implementation details to the reader. Implementing these algorithms robustly can be challenging.
  3. Resource Availability: Researchers may have access to specialized hardware, datasets, or computational resources that are not readily available to others.
  4. Algorithm Tweaking: Researchers may experiment with various parameters and configurations, making it challenging to replicate their exact results without detailed guidance.
  5. Evolution of Research: AI research evolves rapidly, with new techniques and models emerging frequently. Papers may become outdated relatively quickly.
  6. Open-Source Efforts: Some researchers actively contribute to open-source projects, sharing code and making it more accessible and usable.
It's worth noting that efforts are being made to bridge the gap between AI research papers and code. Some conferences and journals encourage authors to publish code alongside their papers, and open-source communities play a crucial role in creating accessible implementations of research.
Overall, while writing papers and programming are distinct skill sets, they are interconnected in the field of AI research, where practical implementations often validate and extend theoretical findings. AI tools, including GPT-3, can assist in generating code or summaries of research papers, further bridging the gap between these two domains.

Dear Research Community,
As a newcomer to the field of research, I am seeking guidance on a specific matter related to affiliations in research papers. Consider a scenario where a student is currently enrolled in an online Master's degree program at a reputable institution, such as the University of Berkeley. This student is preparing to publish a research paper in a peer-reviewed journal.
My question pertains to the formatting of the "affiliation" section. Should it be presented as follows:
Emma Smith Department of Engineering Management University of Berkeley, Berkeley Masters Of Engineering in Engineering Management Email: [email protected]
Or would it be more appropriate to include the term "Online," like this:
Emma Smith Department of Engineering Management University of Berkeley, Berkeley Masters Of Engineering in Engineering Management, Online
Should I make it more specific to write it in affiliation section as a online program
I appreciate your valuable insights and expertise on this matter
Relevant answer
Answer
When submitting a research paper as a student in an online Master's program, you should format the affiliation section to include the essential information that identifies your academic institution and program. Here's how to format it:
1. **Name**: Start with your full name.
2. **Affiliation**: Below your name, list your academic affiliation. In your case, since you are in an online Master's program, you can format it as follows:
- Your Name
- [Name of the University or Institution]
- [Online Master's Program, e.g., "Online Master of Science in [Your Program]"]
3. **University Logo (Optional)**: If your university provides a logo or emblem, you may include it next to the affiliation information.
Here's an example of how it might look:
```
John Doe
XYZ University
Online Master of Science in Data Science
```
If your program has a specific department or school, you can include that information as well:
```
John Doe
School of Engineering and Computer Science
XYZ University
Online Master of Science in Computer Science
```
Remember to check any specific formatting guidelines or requirements provided by the journal or conference to which you are submitting your research paper. They may have their own preferred format for the affiliation section. Additionally, ensure that your affiliation details are accurate and up to date.

Answer
Your model is fairly large given for the rather small sample size. This could be part of the problem. Also, and perhaps more importantly, you have many indicators for each factor. It seems unlikely that these indicators are unidimensional within each factor. In other words, your model may be misspecified, which could lead to the problems that you encounter. I would try a simpler model with fewer indicators and/or fewer latent variables.

Hello Everyone,
I'm in the final year of my MPhil program in Education and I'm on the lookout for potential Ph.D. positions at universities in Canada. Specifically, I'm interested in the realm of "Educational Leadership and Management." I'm wondering if there's an efficient way to identify suitable supervisors at institutions like the Ontario Institute for Studies in Education, or other Canadian universities, who share this specific research focus. Going through each supervisor's research individually is proving to be quite time-intensive. Your insights would be greatly appreciated.
Thank you in advance.

Personally, the first step is to find out the universities in Canada that offer the course you are interested in studying. Once you have done this, you can go through the school portal to identify the academic staff that are available in that area and then go through their work to identify whose specialization best fit your interest. At this point you contact the individual or send expression of interest mail to draw the attention of the staff to your need.
You can achieve this in a day or two. It's a necessary step you should take for best outcome.

Question

I am capturing fluorescent microscopy images of a developmental process with a high degree of variability. I need to compile these images into a "gallery" so that I can see many/all images at once to look for possible phenotypic differences between conditions, which then I can measure through FIJI. The most basic way I can do this is by arranging the images in a Powerpoint, but this method feels manual and has some limitations (explained below). I am hoping someone may know of a better way to compile image data for investigation/curation, maybe through FIJI, R, or a different dedicated program.
Limitations of Powerpoint:
1. Cannot track sample group or ID: When you upload an image into Powerpoint, there is no way to check its filename. So I am forced to upload one image at a time (and make a text box noting condition and ID), which is slow and unideal for batch processing images.
2. Re-formatting and arranging is manual: Re-sizing, cropping, and positioning images on Powerpoint is very manual and there is no record of changes (so making scale bars is hard). The effort compounded when the need arises to re-size or re-position the images later in the process (see #3).
3. Cannot re-order images dynamically based on values: Because the process I am studying is highly variable, it is necessary to compare images at the same percentile between conditions. Thus, I would like to re-order the images by measured values (so that I can compare min to min, mid to mid, max to max, etc.). This is also useful for selecting representative images for presentations/papers.
4. Interactive/Shiny Graph: To further aid in comparing images based on values, it would be nice to have an interactive/shiny scatterplot of the measured values such that when you hover over/select an image the corresponding datapoint in marked in the graph.
Partial Solutions:
A. Keynote: Solves #1 because uploaded images retain the filename information. However, the file format is limited to Macs which limits data sharing.
B. QuickFigures: This FIJI plugin solves #1 and #2, but it is still clunky to use and cannot re-order images.
C. Image Data Explorer: This R package or browser program solves #4 but can only view one image at a time. It also has the advantage of easy annotation of the images by entering values into the corresponding data spreadsheet/dataframe.
Does anyone know of a way/program that solves any of these limitations? Or does anyone have a different way of compiling image data?
Relevant answer
Answer
Hello Nathan,
It may not be easy, but possible. You can rename files according to the parameters (or calculated values), not manually, in Matlab and Python. Also, you can merge labels into them. You can arrange them in adobe illustrator instead of PowerPoint. There may be better ways, but that comes to mind if I have the same issue.
Good luck!

This might be your problem... FORTRAN is different from most other programming languages in that all parameters are passed by reference (pointers). This includes constants (e.g., pi or 298° and even 0.0). To prevent changing the value of pi or zero (yes, it is possible in FORTRAN to change zero) modern compilers have the option to place constraints on some variables passed by reference. If you try to pass something like T=298 call sub1(T) and it croaks, try call sub1(298.) Check the documentation for the library you are using. This would be consistent with the message, "Assertion `m_kind == PROP_CONST' failed"

Dear Colleagues,
im working on a CST program to design a new antenna, how i can draw a curved slot or curved strip?
Thank you
Relevant answer
Answer
To create a curved slot in CST (Computer Simulation Technology) program, you can follow these general steps:
  1. Launch CST and open a new project or create a new design within an existing project.
  2. Select the appropriate simulation type based on your requirements, such as electromagnetic simulation (e.g., CST Microwave Studio) or particle simulation (e.g., CST Particle Studio).
  3. Set up the geometry of your design, including the overall structure and any surrounding objects. Ensure that the dimensions and materials are properly defined.
  4. Use the available modeling tools in CST to create the curved slot. The specific steps may vary depending on the version of CST you are using, but typically, you can employ the following methods:
a. Use a combination of straight segments: Create multiple straight-line segments to approximate the curved shape of the slot. Connect these segments to form the desired curve.
b. Parametrically define the curve: Utilize parametric equations or mathematical functions that describe the desired curved shape. Use the appropriate tools in CST to input these equations and generate the curved slot accordingly.
c. Import a pre-defined curve: If you have a pre-drawn curve or a curve generated in another software, you can import it into CST and use it as a reference to create the curved slot.
  1. Ensure that the curved slot is correctly positioned and aligned within your design. Adjust its dimensions, position, and orientation as needed.
  2. Assign appropriate material properties to the curved slot, including conductivity, permittivity, and permeability, depending on the simulation type and your specific requirements.
  3. Set up the simulation parameters, such as the frequency range, simulation time, and any desired simulation settings.
  4. Run the simulation and analyze the results. CST will calculate the electromagnetic or particle behavior based on your design, including the effects of the curved slot.

Can you specify the editor / package you are using?
If you generate input for a quantum chemistry package, all you have are the positions of the atom nuclei forming an NaCl structure in this case, while the electrons don't know yet where they are and what spin they will get. If you run the program with a suitable method for magnetic properties (which means that basic DFT might not be enough), the electron distribution and spin densities should come out correctly after the calculation.
