QPCR | Fold Changes and Student 's t-tests from qRT-PCR experiment

I'm writing a script to perform LLoD analysis for qPCR assays for my lab. I import the relevant columns from the .csv of data from the instrument using pandas.read_csv() with the usecols parameter, make a list of the unique values of RNA quantity/concentration column, and then I need to determine the detection rate / hit rate at each given concentration. If the target is detected, the result will be a number; if not, it'll be listed as "TND" or "Undetermined" or some other non-numeric string (depends on the instrument). So I wrote a function that (should) take a quantity and the dataframe of results and return the probability of detection for that quantity. However, on running the script, I get the following error:

I try to write a pdf file with a header, logo and table using iText7 in c#.

I never used iText7 before and therefore I don't know how to write text in a paragraph to a fixed position.

Right now I am just using tabstops as anchors for my text. But the problem here is, when the string is too long everything following in the line will be shifted by a tabstop and the "columns" in the header aren't aligned anymore.

The following picture is what I want too achieve:

This picture shows what happens if a string gets too long (in this example I used a long username):

Here is a code snippet I use to write one line of the header:

I have a list of articles obtained from an API, with my dataframe looking like this:

I'm studying some projects in R and was faced with this situation

I am doing error analysis of predictive models and I need to calculate global error, this is, I need to calculate the resultant error from propagation of indirect measurements errors. My data "df" looks like something similar to this

Where 'x' and 'y' are the measured variables, and 'x_se' and 'y_se' the standard errors of these measurements

I have used function 'propagate' from package 'qpcR' for the first row

This is my first ever post so do let me know if there's anything not right or how I can improve, I am a complete novice to all this. For example, I didn't know how to make a proper table for my data so it is in bullet points.

So I currently have a data output from running a qPCR. I have the relative expression of my gene of interest in my treatments alongside the Standard Error, 95% Confidence intervals and P(H1) probability result is due to chance.

good day

is it possible to have multiple instances of a screen each using unique data? for example, i have a 'homescreen' with various buttons for various categories that takes you to a batch list screen unique to that category where you can add batches to be listed. each buttons batch list screen would have unique data to that category but the template for all batch list screens are the same.

ive made a simple example for one category but in order to expand it to the others would i need to repeat the code and create appropriately named .kv files and add each screen to the screen manager.

I have trajectories of some moving objects in a data frame for example three trajectories were considered here as shown below:

I want to collect specific information from data.xml with root[0] 'CaplockSet' contain more than 100 'Caplock' in which I need only author information to be extracted! Kindly help me with this, your support is highly appreciated.
