How to understand the -min/-max options of !dumpheap in WinDBG SOS - windbg

The documentation said it's used for limit the size of the output object, but based on my test, it's not what I expected:
0:000> !dumpheap -mt 000007fee12406a8 -max 400 -min 399
Address MT Size
000000000d1dc1f8 000007fee12406a8 936
000000000d62bed8 000007fee12406a8 1016
000000000d630d00 000007fee12406a8 984
000000000d633aa8 000007fee12406a8 984
000000000d65f368 000007fee12406a8 952
000000000d685ff0 000007fee12406a8 952
000000000d6b2150 000007fee12406a8 952
So how to understand the -min and -max options?

WinDbg's default number format is hexadecimal. 0x400 is 1024 and 0x399 is 921, that explains the output. If you want decimal numbers, use the 0n prefix, e.g. 0n400 and 0n399.

Why are these two IMAP Search results different from one another?

I'm using imaplib, and trying to fetch emails with a certain subject header value.
My code:
res, tmp = self.mail.uid('search', None, 'HEADER Subject "SUBJECT_HERE"')
print(tmp)
print(res)
print("test 2 goes:")
rr, tt = self.mail.search(None, 'HEADER Subject "SUBJECT_HERE"')

I thought that those two commands result in the same results.
But as shown above, those two fetch different emails.
What is the difference??
One (SEARCH) returns message sequence numbers (MSN), which are numbered from 1 to N and change as messages are added and deleted. A message that is number 5 now could be number 4 tomorrow if you delete a message before it.
The other (UID SEARCH) returns UIDs, which do not change as messages are deleted. They're two completely different set of identifiers. A message with UID 5 will remain UID 5 until it is deleted it (or moved, etc.).
The UID will never reused in that incarnation of a folder. If the folder is deleted and recreated, or the mail server is rebuilt, the folder's UIDVALIDITY should change so you can detect that your cache is no longer valid.

RMarkdown: Creating two side-by-side heatmaps with full figure borders using the pheatmap package

I am writing my first report in RMarkdown and struggling with specific figure alignments.
I have some data that I am manipulating into a format friendly for the package pheatmap such that it produces heatmap HTML output. The code that produces one of these looks like:
cleaned_mayo<- cleaned_mayo[which(cleaned_mayo$Source=="MayoBrainBank_Dickson"),]
# Segregate data
ad<- cleaned_mayo[which(cleaned_mayo$Diagnosis== "AD"),-c(1:13)]
control<- cleaned_mayo[which(cleaned_mayo$Diagnosis== "Control"),-c(1:13)]
# Average data across patients and assign diagnoses
ad<- as.data.frame(t(apply(ad,2, mean)))
control<- as.data.frame(t(apply(control,2, mean)))
ad$Diagnosis<- "AD"
control$Diagnosis<- "Control"
# Combine
avg_heat<- rbind(ad, control)
# Rearrange columns
avg_heat<- avg_heat[,c(32, 1:31)]
# Mean shift all expression values
avg_heat[,2:32]<- apply(avg_heat[,2:32], 2, function(x){x-mean(x)})
#################################
# CREATE HEAT MAP
#################################
# Plot average heat map
pheatmap(t(avg_heat[,2:32]), cluster_col= F, labels_col= c("AD", "Control"),gaps_col = c(1), labels_row = colnames(avg_heat)[2:32],
main= "Mayo Differential Expression for Genes of Interest: Averaged Across \n Patients within a Diagnosis",
show_colnames = T)
Where the numeric columns of cleaned_mayo look like:

All of this code is wrapped around the following header in the RMarkdown environment: {r heatmaps, echo=FALSE, results="asis", message=FALSE}.
What I would like to achieve is the two heatmaps side-by-side with black boxes around each individual heat map (i.e. containing the title and legend of the heatmap as well).
If anyone could tell me how to do this, or either one individually it would be greatly appreciated.
Thanks!

Connecting points in qqplot in MATLAB

I am trying to plot a qqplot graph for different data samples. I am able to draw it for individual data samples. How can I draw a qqplot graph for multiple data samples? Also, I want to connect all the points with a line and color for each data set to differentiate them. How can I achieve this in MATLAB?
I am getting the output as below:
I am trying to get the output in the below format(qqlplot for 4 samples).
I am loading the data from csv file into matlab.
Next, drawing the graph using the function qqplot(1mb);

Multidimensional scaling matrix error

I'm trying to use multidimensional scaling in Matlab. The goal is to convert a similarity matrix to scatter plot (in order to use k-means).
I've got the following test set:
London Stockholm Lisboa Madrid Paris Amsterdam Berlin Prague Rome Dublin
0 569 667 530 141 140 357 396 570 190
569 0 1212 1043 617 446 325 423 787 648
667 1212 0 201 596 768 923 882 714 714
530 1043 201 0 431 608 740 690 516 622
141 617 596 431 0 177 340 337 436 320
140 446 768 608 177 0 218 272 519 302

190 648 714 622 320 302 514 573 755 0
I got this dataset from the book Modern Multidimensional Scaling (Borg & Groenen, 2005). Tested it in SPSS using the PROXSCAL MDS method and I get the same result as stated in the book.
But I need to use MDS in Matlab in order to speed up the process. The tutorial on the site: http://www.mathworks.nl/help/stats/multidimensional-scaling.html#briu08r-4 looks the same as what I'm using above. When I change the data set as what is displayed above and run the code I get the following error: "Not a valid dissimilarity or distance matrix.".
I'm not sure what I'm doing wrong, and if classical MDS is the right choice. I also miss the possibility to say that I want the result in three dimensions (this will be needed in a later stage).
Your matrix is not symetric, check the indices (9,1) and (1,9). To quickly find asymetric indices use [x,y]=find(~(D'==D))
