## microinteractions – Should clicking middle mouse wheel always open link in new tab?

What do you mean by ‘using scroll’?

If it’s a link, first thing is to make sure that you don’t break the web browser’s default functionality, and users can still open the link in new window using the normal methods – right clicking, cmd-clicking, ctrl-clicking, long press on touch devices.

Having site-specific ways of opening links in new window need to be learned, but using browser standards taps into existing, learned behaviors.

## Click scroll to open in new tab – good practice?

Is it a good practice to provide "open in new tab" option, by clicking link using scroll? Do you know any resources or research on this; any reasons why/when it shouldn’t be a default option?

## How to increase number of open connections for mongoDB from clients (C#)

mongoDB v4.0.4 >> replica set of 3 nodes (not sharded)

Previously

``````su - mongo7937
No directory, logging in with HOME=/
\$ ulimit -Hn
1048576
\$ ulimit -Sn
1024
\$

cat /etc/pam.d/common-session | grep pam_limits.so

cat /etc/sysctl.conf | grep fs.file-max
``````

changed to

``````su - mongo7937
No directory, logging in with HOME=/
\$ ulimit -Hn
1048576
\$ ulimit -Sn
64000
\$

cat /etc/pam.d/common-session | grep pam_limits.so
session required        pam_limits.so

cat /etc/sysctl.conf | grep fs.file-max
fs.file-max = 2097152

sysctl -p
``````

So earlier my max number of connections were limited to 818 which is 80% of 1024.
As per recommendation from mongoDB documentation I’ve increased the limit to 64000 but still when mongo c# client reaches max open connections to 818, my mongoDB abruptly stopping.

Is there working command set for c sharp driver to limit number of connection client end ?
because whatever we tried is not working, can someone share if that is working for you.

Else can someone tell me the right steps to limit number of open connections from mongoDB side and at server user level.

## Are there paths of exact forms joining two symplectic structures on open manifolds?

There is a Theorem of Conolly, L$$hat{text{e}}$$ and Ono which states that on a closed simply-connected $$4$$-manifold two cohomologous symplectic forms can be joined by a path of non-degenerate $$2$$-forms.

I was wondering is there any open analogue of this theorem? For example:

Let $$omega_0$$ and $$omega_1$$ be two cohomologous symplectic structures on an open simply-connected $$4$$-manifold $$M$$ which are equal on the complement of some compact set. Are there any results on the existence of a path $${omega_t}_{tin [0,1]}$$ of non-degenerate $$2$$-forms joining $$omega_0$$ and $$omega_1$$ such that all $$omega_t$$ are equal on the complement of some compact set?

I am especially interested in the case $$M=mathbb{R}^4$$.

## 3 controls on the tree – select, expand, open

We have a tree with one click to select and double click to expand. This works well for our users and is something that would be better to keep unchanged.

Now we need to add another action to some of parent elements – to open this parent’s content in a new window (this contains not only child elements, but also additional info about the parent). What could be the best option for this?

Considered solutions:

A) Add “open” to the action bar – not ideal, because an action which is detached from its object may be not obvious and users may not look at the action bar.

B) Add a button on the parent element – if add it on every element it will be too many buttons. Maybe add to only the selected one, then the question is where to place it.

## st.statistics – Binary Regression : Is this an open problem in Mathematics/Statistics?

Let $$X$$ be a random variable which takes values from $$Omega = (0,1)^m$$ with a probability distribution $$p(x)$$. Assume $$p$$ is a BV function with non zero total variation and $$p(x)>0forall xinOmega$$. There is a discrete random variable $$Y$$ which takes values from $${0,1}$$ and depends on $$X$$ with $$P(Y=1/X=x) = eta(x)$$. Assume that $$eta$$ is also a BV function with non zero total variation and no removable discontinuities.

Binary Regression Problem

Given no other information except $$n$$ samples of the random variable pair $$(X,Y)$$ drawn iid, that is $$(x_1,y_1),(x_2,y_2),ldots(x_n,y_n)$$ one need to give a method for computing $$tilde{eta}_n$$, an estimate of $$eta$$ such that $$limlimits_{ntoinfty}|tilde{eta}_n-eta|_{L^2(Omega)} = 0$$

This problem I believe is open (needs confirmation as I have little knowledge on statistics literature). There are methods like $$k$$-nearest neighbours method, which solves when $$eta$$ belongs to a narrower class of absolutely continuous functions. There seem to be some methods when $$eta$$ is a Lipschitz continous function, but with known Lipschitz constant.

For $$eta$$ belongs to class of all BV functions with nonzero total variation (a wider class), I believe I have come up with a method and proof of convergence. Is this sufficiently interesting to be considered for a mathematics journal or it should be considered for a (mathematical)statistics journal? How interesting is this problem for mathematicians and/or statisticians?
