I'm trying to connect 32 I²C "root of trust" NXP A71CH devices.    I'm trying to multiplex 32 devices for that chip.   I'm looking for a very fast way of multiplexing those 32 devices, an idea or schematic or a design.  The only solution that I found is to use an FPGA.  Is there a clever solution with just normal embedded microcontrollers ?  One chip costs 50ms, If I want to do 1000 signing, it would cost 1000*50ms. What I want to achieve is to have 1000signing with just 50ms cost. Is there a way of that without using FPGAs ?! Only with discrete components
I'm trying to connect 32 I²C "root of trust"  devices.    I'm thinking about a good way that does that, I mean what kind of communication should I use? A digital multiplexer that selects a device? but based on what? switching on the VDD source? but that needs reinitialization of the device and that takes time.
The level 4 spell Polymorph requires concentration to maintain.  The subject retains their personality and alignment, but they have the mental statistics of the new form, which must be a beast and cannot speak or cast spells.  If a caster targets themselves with this spell, can they concentrate to maintain it, or does this depend on the mental statistics of the beast form they choose?  This situation certainly occurs in practice, since Wizards reaching level 10 in the School of Transmutation gain the Shapechanger feature.  This allows them to cast Polymorph, but only upon themselves and only to change into a beast of CR 1 or lower.  Beasts with CR 1 or less range in Intelligence from the Giant Eagle (Int 8) to the Frog (Int 1). What is so called meta-game in StarCraft 2?    What other games have this meta-game? How does the size of insert affects the rate of Homologous Recombination in yeast? When performing genetic knockouts in yeast using homologous recombination to replace a target gene sequence via a vector DNA, does the region between the flanking regions in the vector have to be the same length as the site of recombination in the host cell's gene? Right identity and Right inverse implies a group Suppose $k$ is a field that is finitely generated as a ${\mathbb Z}$-algebra.

Finding the uniquely determined region of a PDE (a) Solve the equation $yu_x+xu_y=0$  with the condition $u(0,y) = e^{-y^2}$.

A more clear explanation is appreciated I have 16GB RAM. Do I need 32GB swap? Windows 7 won't boot after installing Ubuntu 11 Evaluating $\lim\limits_{n\to\infty} e^{-n} \sum\limits_{k=0}^{n} \frac{n^k}{k!}$ I'm supposed to calculate: $$\lim_{n\to\infty} e^{-n} \sum_{k=0}^{n} \frac{n^k}{k!}$$ By using WolframAlpha, I might guess that the limit is $\frac{1}{2}$, which is a pretty interesting and nice result. I wonder in which ways we may approach it. What is the difference between a deep copy and a shallow copy? It has been suggested by my employer that i should get the Hepatitis B vaccine to protect myself.  I have had two of the three parts, but this is the first time i have had a vaccine in more than one session.  The vaccine is in 3 doses, each around a month apart, followed up by a blood test.  Why is the Hepatitis B vaccine split into 3, any what is the blood test for at the end? Why do we use AC for long distance transmission? Why do we use AC (Alternating Current) for long distance transmission of electrical power?  I know that AC is such a current that changes polarity (magnitude and direction) and has fixed poles. How does the secondary effect of the Heat Metal spell work? The  spell description states:  If a creature is holding or wearing the object and takes the damage from it, the creature must succeed on a Constitution saving throw or drop the object if it can. If it doesn't drop the object, it has disadvantage on attack rolls and ability checks until the start of your next turn...  I am unsure how this disadvantage mechanic functions as a whole. When do you suffer from it and in what ways (if any) can you end it? For example: What happens if you fail the save but cannot drop the object? Does dropping the object later, on your turn, do anything? What happens if you succeed on the save?  Does dropping the object later, on your turn, do anything? I would like it to be assumed that ; however, heat metal can still force you to drop the weapon. I would also like it to be assumed that . Raise all windows with a specific title I'm trying to find a way to raise all the windows that have one, specific title.  For example, I have two windows named superconky (yes, you guessed it, I'm trying to get conky running in lubuntu).  I have a command I got from the LXDE forums: sh -c 'wmctrl -k on; wmctrl -a superconky;'  I use it to show the desktop, except conky. It works perfectly, but only if you have one conky. If you have two or more, you get left with one and all the others minimized.  So, what should I do to raise all the windows?  Thanks in advance. A Tweedie distribution can model skewed data with a point mass at zero when the parameter $p$ (exponent in the mean-variance relationship) is between 1 and 2.   Similarly a zero-inflated (whether otherwise continuous or discrete) model may have a large number of zeros.  I'm having trouble understanding why it is that when I do prediction or calculate fitted values with these kinds of models, all of the predicted values are non-zero.  Can these models actually predict exact zeros?  For example  library(tweedie) library(statmod) # generate data y &lt;- rtweedie( 100, xi=1.3, mu=1, phi=1)  # xi=p x &lt;- y+rnorm( length(y), 0, 0.2) # estimate p out &lt;- tweedie.profile( y~1, p.vec=seq(1.1, 1.9, length=9)) # fit glm fit &lt;- glm( y ~ x, family=tweedie(var.power=out$p.max, link.power=0)) # predict pred &lt;- predict.glm(fit, newdata=data.frame(x=x), type="response")   pred now does not contain any zeros.  I thought the usefulness of models such as the Tweedie distribution comes from its ability to predict exact zeros and the continuous part.  I know that in my example the variable x is not very predictive. Confused By Copyright Rules What statistical test to use for discrete predictor and response variables? I'm doing a statistical analysis of a model for college. It's modelling a bear catching fish and I'm asking will the amount of time taken to digest the fish have an effect on the amount of fish caught? (stupid question I know!) So the predictor variable is the amount of fish the bear can eat before it needs to digest and the response variable is the amount of fish it catches. The predictors varies between 1 and 30 in integers and the response is also in integers. I repeated each level of the predictor 5 times creating a sample size of 150 altogether. I was thinking of just using a simple correlation test such as cor.test in R, but I've read online that this is for continuous data. Does that matter or would this test still be appropriate?
