Hey guys. It's Trina and today I'm going to
be going over my TBR for May. I have
been combining my monthly TBR's along
with the new releases of that month that
I am most anticipating but I actually
did a completely separate video this
month for all of the May releases I'm
looking forward to because there are just
so many and this video would be way too
long if I did both. As a reminder, I do
check in with my TBRs at the end of
every month in my reading wrap-ups and I
did horribly in the month of April. I only
had four books on my TBR and I only read
two of those so this month I'm going to do
things a little bit differently. Instead
of just naming a bunch of specific
titles I want to read, this month I'm going
to give myself a few reading goals.
which this is something that I have
done in my TBR s several times in the
past. I just haven't done it in the past
couple of months. First of all on my TBR
there is one specific book I know I need
to read this month and that is Once and
For All by Sarah Dessen. I've never read
a Sarah Dessen book but I was sent to
this one by Penguin Teen for review.
This one is coming out in June so I
want to read it this month in order to
have time to read it and get a review up
before it comes out. As far as I know,
this is a contemporary romance in which
the main character's mother is a wedding
planner so the main character's like really
wrapped up in the chaotic world of
wedding planning and that sounds really
interesting to me because I am married
and remember how chaotic wedding
planning was so I think that this one
may be pretty relatable. My next thing on
my TBR is a reading goal. I want to read
one book set in South America this month.
It was one of my goals for the entire
year to read around the world more and
South America was a region that I just
hadn't read very many books that were
set there so I took to Twitter this
past month and asked for some
recommendations of books set in South
America that fit my reading tastes and I
have a couple that people suggested
that are kind of options that I have for
this goal and I just want to read one of
these. So the first one I have that
sounds super interesting to me is
Perfect Days by Raphael Montes and this
one is about a man who falls for a girl
but she rejects him and he starts to
stalk her and he ends up kidnapping her
to take her on this like weekend trip or
something, I guess thinking he'll make
her fall in love with him and it just
sounds really creepy. I've heard
people compare this one to the book You
buy Caroline Kepnes like in terms of
that there is a stalker as the main character and
I did enjoy You because it was very
creepy so I'm thinking that this one
might be something up my alley. This is an
adult thriller by the way. And then my
other option I have is Origin by
Jessica Khoury. This one is a YAscience
fiction story. It's about a girl who is, like I
think she's a clone or something? Like
she was made in a lab which is like in the Amazon rainforest.
She's been enclosed in this lab her
entire life and then one day she like
gets out and discovers the real world, so
that sounds like really interesting and
mysterious. So I just want to read one of
these books this month. I don't have to
read both of them. I just want to read
either one of these books or any book
set in South America this month. My next
reading goal is that I want to read at
least two 2017 May releases. There are
so many books coming out this month. I
think there were 15 that I mentioned in
my May anticipated releases video and
there's no way I'm going to get to all
of them and it's just going to bog down
my TBR for the rest of the year with me
wanting to read all these books so I
want to make a little bit of progress on
it. I was to read at least two new releases
of this month. My last reading goal is
that I want to read at least two books
that I already own. So nothing that I buy
after May first, anything that I already
own. There are a bunch of books I just
got for my birthday, there are a bunch of
books that I have been sent for review
this year, there are a bunch of books
that I have had since last year and
haven't gotten to and they're piling up
and I just need to start making more
progress on the books I already own so
this month I also want to read two of
those. So that's a total of six books on
my TBR. I want to read Once and For All by Sarah Dessen,
one book set in South America, two books that
are releasing in May, and then two books
that I already own. So at the end of the
month I will check in with this list in
my May reading wrap-up and hopefully
I'll do well this month since it's a
little bit of a looser structure. So wish
me luck and check in with that wrap-up
to see how I did. I'd love to hear what
you guys are planning to read in May.
Thank you so much for watching and I
will see you in the comments, Bye!

nanoHUB-U Nanophotonic Modeling L1.20: MPB for 3D Lattices and Bandgap Maximization - Duration: 5:45.
[Slide 1] Welcome everyone.
So, continuing from the last lecture about triangular lattices,
now we're going to look at how MIT Photonic Bands, or MPB could be used for
3D lattices, as well as maximizing band gaps.
[Slide 2] So, the first kind of 3D lattice you may be interested in,
because it has a large band gap, is the diamond lattice.
And so this actually shows you how to can define a 3D lattice with diamond.
And so, the key thing is, first of all, that the basis is different in size than
for the previous types of structures which had size of 1 in each direction.
But then second,
you can see that the basis directions are essentially like y plus z.
And then x plus z, and then x plus y.
And then we actually come up with a fairly complex looking list of special k points,
but these can be also looked up in the literature in case you don't know them,
for the face center cubic lattice.
And so it's not just the gamma point but also the X, U, L, W and K points.
[Slide 3] And so now moving on, you can see that for
the diamond lattice, we are going to need to define two unit atoms per cell,
and these will have a certain specified radius and dielectric constant
which we can define up here, and there'll be at a distance of one eighth
x plus y plus z in the plus and minus directions, or so in other words,
the distance between them will be one quarter times the square root of three.
And because this is a 3D calculation we might want
to use the slightly lower resolutions, so
instead of the 32 resolution per unit distance that we had before,
now we use 16 so that gives us the 16 by 16 by 16 grid or
about 4096 overall grid points.
And we have a mesh size of about five bands to reduce the computational load and
then we can actually run the calculation using the run function.
And now we don't use run TE or run TM, because it's a true 3D calculation.
[Slide 4] So, TE and TM modes are not well defined.
And then the kind of final result that we get for the band structure looks
like this, and I've just added kind of this extra yellow part.
But you can see this matches very closely
with the results that we showed previously for the 3D photonic band gap.
And you can actually explicitly calculate
the exact size of the band gap relative to the mid-gap point.
And you can see that the size is about 10.6%.
[Slide 5] And then you can also visualize the fields very easily, so you can see that
the fields in this sicolic VIS5d output,
which is kind of invoked here, which have vocalization either
at the high di-electric regions which is shown in blue or
in the low di-electric regions shown in kind of like this teal color.
[Slide 6] And then the third band gap just above or sorry, third band just above the bandgap
actually would be localized explicitly away from the high dielectric regions.
Which is kind of expected.
And that's why it has more energy.
Because the average epsilon is much lower.
[Slide 7] Now in order to maximize bandgaps like the diamond band gap that I just showed you.
Then we can actually invoke what's called Brent's Method.
And Brent's Method is actually a very effective way, if you're doing a single
parameter optimization, to very quickly evaluate multiple options.
And you can see from numerical recipes kind of how it works, so
you would create an initial bracket between two points, and
you would assume that you have a concave function between them.
And you would basically fit the parabola at the initial
set of points that you calculate, and then try to evaluate it right at the center.
And then of course, it probably doesn't exactly conform to a parabola,
so then on the next iteration you would define like a tighter bracket and
then you would basically find the new optimum with
the new parabola and then repeat until the bracket is approaching your tolerance.
[Slide 8] And so this allows you to quickly find the optimum.
And so you can actually implement this also numerically in scheme, and so
if you define that the bandgap has a certain value as a function of radius,
and so we're only optimizing radius of the spheres, nothing else, and
then we basically would define the gap, retrieve the gap, and
then basically run the optimization algorithm using the so-called
maximize function which is defined in lib ctl which is part of MPB essentially.
And then we can actually output the maximum gap and
then you can find that the true maximum would actually give us
a much larger gap size and a different radius than we calculated earlier, so
that's a nice demonstration of how it works, and so in the next calculation or
next lecture we'll actually talk more details about what else we can do with mpb

Queen Elizabeth's Prepares For Final Moments, Gives Up Beloved Corgis Willow & Holly! - Duration: 2:16.
Queen Elizabeth is 89 years old, and her health has been steadily deteriorating.
It is only a matter of time before England�s matriarch gives up her throne.
Queen Elizabeth just made a huge sacrifice that has everyone buzzing, because it signifies
that the end of her reign is coming closer.
Anyone who follows the Royal Family knows that Queen Elizabeth is madly in love with
her corgis at one point she owned 13 of the little yappy dogs � but according to a new
report the Queen just gave away all of her dogs, meaning that she knows her days are
numbered.
Although Queen Elizabeth has been breeding the Welsh corgis for over 60 years, her pack
has thinned down over the past decade and she only has two remaining Holly and Willow.
A Palace insider dished in this week�s edition of GLOBE Magazine, �The Queen doesn�t
breed anymore.
She doesn�t want to leave any pets behind when she passes away.
She worries about tripping over the dogs and breaking a hip or worse.
But, we worry that her decision to give up her dogs is a sure sign that Her Majesty is
facing her last days.� Queen Elizabeth is 89 years old, and it has
been reported that she is battling heart problems, among many other medical ailments.
Over the course of the last few years Queen Elizabeth appears to be weaker and weaker
every time she steps out for a public event.
The fact that she is giving up her corgis is a clear indication that even she knows
her days are numbered.
It is noble that she is taking care of her dogs now so that after she passes they won�t
get set aside or lost in the madness that is sure to ensue.
How sad is it that Queen Elizabeth has begun making preparations for her death?
Who do you think will take care of the corgis?

Defence Minister's Stolen Valor - Duration: 0:47.
Mr. Speaker, no one will ever take away from the Minister of Defence's
actual service record.
But people in the military have a name
for what he did – it's called Stolen Valour:
When someone takes credit for the brave actions of another.
And what he did was wrong.
And now he has lost the confidence of our men and women in uniform
and they need to have confidence in their leaders
especially when they're putting their lives on the line.
So will the Prime Minister
remove the Minister of Defence?
The Right Honourable Prime Minister.
Mr. Speaker, when we make a mistake, Canadians
expect us to apologize
and-
to-
to acknowledge that mistake. That's
exactly what we did. That's why
the Minister of Defence
continues to have my full confidence.

us to tell us what she's found.
thanks for being
here gina.
so how many properties have been
purchased
for the town portion of the

early due to opportunities when
something was for sale,
and also said the price of the
properties would
only go up if it waited.
and so what's the city doing
with the land until
rail along that portion...some
16 of
want to use the land
temporarily.
i found out how much money that
is
leases are helping ...but some
aren't happy that
it's happening in the first
place.
so i'm finding out what's
changing to prevent a
lot of properties from just
sitting empty for
years.

Underreported: How Building a Border Wall Changed San Diego | The Daily Signal - Duration: 4:40.
Build that wall! Build that wall! Build that wall!
While the prospect of building more walls along the border has become hugely controvercial
under the Trump Administration, the reality is, for many areas along the border - like San Diego -
building a wall is nothing new.
The fence turned one of the most dangerous neighborhoods in America into one of the safest.
I grew up here, I learned to play here, we used to cross the border back and forth in the old days chasing rabbits with our bow and arrow.
Kelsey: How has it changed between then and now?
Well, in the eighties, it started getting very ugly. The criminal element got really big. The valley literally became one of the most dangerous neighborhoods in America.
And once it reached that critical stage, people realized they had to do something, the criminals were taking advantage of a lack of control.
I worked here when the fences weren't here. When it was just a chain link fence over there. It was out of control. There was 300 people here. They'd put babies over the fence. They were throwing soccer balls with heroin over.
In 1986, before any walls or fences separated the border between San Diego and Mexico,
Border Patrol agents in this region apprehended 629,656 people, which accounted for one-third of all border apprehensions that year.
Construction of the primary wall, which covers 46 miles and stands between 8 and 10 feet tall, began in 1991.
And construction of a secondary fence, which stands between 14 and 18 feet high
covering 13 miles of the border, began in 1997.
Today, the San Diego sector accounts for only a small fraction of total apprehensions along the border each year.
You actually got businesses right on the border now. If you take a picture of ariel photograph and just shoot down the fence, you'll see Mexico has built right to the fence.
They have businesses and homes right on the fence. We've been backed off and been intimidated because of the illegal and the crime problem.
The fence has allowed businesses on the United States side to come up and come up closer to it.
And what's interesting is that people come in legally from Mexico shop, in these shops in the United States and then go back to Mexico
but they do it through the gate.
It took me only about 15 minutes, so it's not hard at all... I'm sure there are other days that are a lot busier then today.
So, that wasn't my case today, so, it was pretty easy.
The city has even gone so far as to put in parks and want to put campgrounds up here because of the decreased in criminal activity
and the safety measure that have been put in place just by us being here. Most community leaders will admit easily that it's because of Border Patrols here that these things are possible
because they weren't, back in the day, before those barriers and before the increased manpower was here.
I think people are getting so obsessed with symbolism, rather than substance.
San Diego has the largest land port of entry in the world, we have the biggest gate in the entire world here.
But we also have a high fence... they have a saying in Mexico -
Good fences make good neighbors.
Since building a wall, crime rates in San Diego have dropped dramatically.
In 1989, there were more than 100,000 total crimes committed, and last year, there were just under 34,000.
Do you think, that there are any lessons learned in San Diego and that the type of infrastructure
that's put into place here could, or should be replicated in other areas?
Physical structures can be a major aid at law enforcement.
And the people that really are the victims when you lose law enforcement are the weak and the vulnerable.
The people that die along this border - I mean, I've rescued drowning illegals
that would be pushed during the flood period by smugglers.
They were walking across, they didn't know the dangers.
The fence sends a very clear message to everybody before they even try to cross the border. No, don't come here the wrong way.
If you wanna come to America come here through the gates.

nanoHUB-U Nanophotonic Modeling L1.16: Eigensolvers for Bandstructure Calculations - Duration: 6:26.
[Slide 1] Hey everyone, welcome to lecture 1.16.
So now we're going to talk about, extending on the previous lecture,
how we can use Eigensolvers to do bandstructure calculations, and
[Slide 2] before we were saying that the steepest descent method
can actually be very effective for so-called convex problems.
So let me just explain a little bit more about what is
the meaning of convexity in general.
So what that means is basically within an open set of values
that there is only one optimum.
So you don't have a double or triple peak that are all the same for example.
And then also that the function that you're looking at itself.
Is continuous and twice differentiable.
So that means that it's very smooth, doesn't have really jagged jumps or dips.
And then also something that's very critical is that the midpoints are always
lower than the edges and
you can express it with this formal mathematical framework.
But you can basically see what it looks like using this graph, okay?
So that just means, it's kind of like a smooth parabolic type function, right?
And so it could be an actual parabola like x squared, or
it could be a hyperbolic sine function.
It doesn't actually matter that much.
If it's a very nice function.
Of course, not all problems are quite that nicely behaved.
[Slide 3] So we do have other methods to deal with those issues.
So in some cases we may need to have like iterative process to, kind of,
narrow down the values that we are interested in.
So here you can actually see that we have written down two separate formulations for
how do we set up and then calculate these problems.
And so in the first case, you can see we have defined a bit, basically a set of
these matrices which are composites of some of the elementary matrices that we
discussed in the last lecture and you can see that there are basically two different
formulations which are slightly different from the Block Rayleigh minimization that we had earlier.
On the left-hand side is the so-called Fletcher-Reeves formulation, and
then we also have this so-called Polak-Ribiere method.
And then in this case, we subtract this extra G naught term.
So these are actually very similar except for that one distinction.
And both require what's called preconditioning which allows us to
kind of provide initial guess for what kind of results we're going to get.
[Slide 4] And then this is showing what the results are for each of these three methods.
If we have steepest descent method, you can see that for
the initial iterations, it performs just as well as any of these other methods.
But it actually doesn't converge quite as quickly
when we get really close to the answer.
However, if we use the Polak-Ribiere or Fletcher-Reeves method, you can see it
actually drops like a rock once we get to a certain number of iterations.
And so it converges so well at that point that you never need really more than,
you need 30 or 40 iterations whereas you could need hundreds of iterations for
the other method if you need a high level of accuracy.
[Slide 5] So how do we actually get those preconditoner matrices that I
was talking about, the k?
So there's actually a couple ways to do this.
What we're trying to do in practice is make a rough guess at the inverse
of the Maxwell operator or Eigen operator.
And so one method is this so called diagonal method in which we just write
down that the Eigen operator would be dominated by k + g squared
which is just a very rough simplification of the curl of epsilon inverse of curl
operator by assuming that epsilon-inverse is very boring.
And it acts basically like an identity matrix.
However, there is a non-diagonal method as well, which is important for highly
contrasting structures with a lot of periodicity and other interesting behavior.
And so then here you would actually project the epsilon inverse and
explicitly calculate this A.
[Slide 6] And so this is kind of showing what happens when you perform
the three different calculations.
First of all, you can see in red what happens when you have no preconditioner whatsoever,
It does start to converge after a number of iterations.
It takes a while.
In the case of the diagonal preconditioner, which as you can see has
the advantage of simplicity, it actually already gives you a much better
convergence performance, especially as you get to tens or hundred iterations.
Overall it's certainly a big improvement.
But the transfers projection pre-conditioner
gives us the best overall performance in green.
[Slide 7] And then there's another type of Eigensolver that we can use called
Davidson Eigensolver.
And then this is where you would actually create a sub-space V,
which would have the eigenvectors that we care about.
So, of course,
related to the previous like Raleigh Ritz minimization that we talked about earlier.
But we also calculated a residual Y,
as it's called, which is equal to the product of V and YV.
And then we would add that I'm sorry.
The residual B BYL- AY and then we would add that to V using the D operator.
[Slide 8] And then if we look at the performance of Davidson compared to conjugate-gradient.
It turns out that Davidson may kind of break even
with conjugate-gradient at small number of iterations, but
at the end of the day it doesn't actually converge that much better.
There is a kind of maybe a small window where it looks like a little better.
Around 10 to 20 iterations.
But overall we won't end up using that because it's not as big of a benefit.
And then the next lecture we'll talk a little more about
the details of how do we obtain this calculation.

nanoHUB-U Nanophotonic Modeling L1.15: Methods for Solving the Photonic Bandstructure - Duration: 6:27.
[Slide 1] Hey, everyone, welcome to lecture 1.15, continuing on the last lecture where we
discussed whether the basic ways to set up the solution to the Maxwell-Eigen problem.
Now we're going to go into more details about how do we actually solve it.
[Slide 2] So there is one key challenge in this sort of problem.
As you recall we are using fast Fourier transforms because we can
naturally represent some of the components of the Maxwell Eigen operator,
which is a curl operator in the Fourier domain.
But then we also found that that also forces us to put epsilon
inverse in the Fourier domain.
Unfortunately epsilon inverse could very easily
become discontinuous in the Fourier domain which could risk our convergence.
So we can actually perform a physically motivated averaging process for
epsilon inverse which amounts to assuming that e parallel
is continuous across boundaries and then D perpendicular, the displacement field.
Is continuous across boundaries.
So once we have that information or assumption into our model,
which is kind of represented by this equation here.
And it's based on this projection operator where ni is the normal direction.
And we've constructed it as an elder product of those two ends.
Then we get actually much more reliable result.
And you can see on the right hand side if we have no averaging,
we kind of get this erratic reduction in error as we go to higher resolution.
But then if we use the epsilon averaging we actually get it to converge much more
quickly and reliabily.
[Slide 3] So that's actually a big advantage for us.
And then in terms of implementing the actual solution in more detail.
Remember we only want to work with P bands because that's much more
computationally efficient and reduces our storage.
So we have two choices that we can really consider.
First is conjugate-gradient minimization of the Block Rayleigh quotient.
And then the second is called the Davidson method,
which is related to Lanczos' methods.
And of course, probably most of you don't know what that is, which is fine.
But I'll explain that right now.
[Slide 4] So, the Rayleigh quotient is oftentimes used in understanding
the variational principle to minimize the wave function or the energy of a particle.
And so, it amounts to you writing down an energy or
lambda naught in general which would be kind of the minimum of the ratio of
taking the outer products of y naught some sort of
trial function with your a operator divided by the outer
product of y naught with the b operator which goes into the the eigenproblem.
Recalling that, of course, there is this extra like auxillary
matrix in the eigenproblem that's being formulated.
And then what you do in the Rayleigh-Ritz algorithm is you first would minimize for
y naught which is basically your first trial function, and then you would then
create a new y1 that would be a trial guess that is completely orthogonal to y naught.
So that means you won't allow any y naught components because you're assuming,
that every new solution is orthogonal to the previous solution.
And then you can build that up by a step-by-step minimization.
And you can either do one at a time, or
you can do it in small blocks at a given time until you get to p bands.
However many bands you need.
So you're not necessarily strictly limited number of bands.
[Slide 5] And so here we've actually written out some of the equations for
a Block Rayleigh quotient minimization.
So you choose Y in an n by p matrix, and then we minimize the trace
of the outer product of Y dagger with A and
Y, subject to the constraint that Y dagger BY is equal to 1.
And so this is essentially a generalization
of that Rayleigh–Ritz method that I just showed you.
Just doing it in a block configuration that I mentioned earlier.
And then we can also perform an unconstrained minimization by transforming
to a Z basis which can make things a little faster for
us computationally rather than having to strictly enforce this condition directly.
[Slide 6] Now the second method that I mentioned that we can use is Iterative Eigensolvers.
With either Steepest descent or Conjugate-gradient method.
And so in the steepest descent method
you can kind of think of it like climbing up a hill.
So, if you are climbing up a hill, you have the advantage,
not only do you know your position,
but you can also look at the gradient or kind of the slope of the ground below you.
So, if you know you want to get to the top of the hill,
it makes sense that you just go in the direction that has the steepest slope.
Until you get all the way to the top, right?
And so that's what it amounts to.
But in the conjugate gradient method, it's related, but a little more sophisticated.
Because you would actually not only use the current gradient, but
you'd also remember the prior steps that you took in climbing up that hill.
And so that's kind of illustrated here.
And you can see that actually allows you to take just a finite number of steps,
but very quickly to ascend that hill.
Because in this case, unlike the real hiker,
you actually have the ability to take either very small or very large steps.
You can calibrate the step size very well to the given problem.
So for some types of problems which are fairly easy
to optimize so-called convex problems,
then these actually behave beautifully.
In other types of problems, it's a little more challenging.
So then we'll explore that next time.
-------------------------------------------
nanoHUB-U Nanophotonic Modeling L1.19: MPB for Triangular Lattices - Duration: 3:18.
[Slide 1] So, lecture 1.19, welcome.
So, we were just talking about how to use MIT photonic bands to do
practical calculations of the type that we showed earlier in the unit.
And now we're actually going to explore specifically what happens with triangular
lattices.
We had said that triangular lattice is actually fairly similar to
the square lattice except for a couple of changes.
We created a noncartecian basis and we picked different k points.
[Slide 2] So those are the most important differences.
And then if we run that kind of calculation, as you can see here,
using this command line, and then convert the output
of the HDF5 file which is basically a database storing
the epsilon as a function of position and then convert that into an image.
Then we actually get something that looks like this,
which looks like a very distorted elipsoid structure.
So then the question is, so why does it look so distorted?
We don't actually necessarily know right away.
But this is a big problem.
[Slide 3] So, it turns out that actually this is coming from a misinterpretation
by the h5 tipping command line of the actual output in the basis
that was shown there as different from the cartesian basis.
And so that can actually be fixed using a separate free utility called mbp-data
which is shown up here, and so then you basically would use these command
line parameters to basically set up the number of periods that are used and
the resolution and so on, on the epsilon.h5.
Creates a new dataset called data-new and then if we run h5 to ping on the data-new,
then you actually see output just like this and
so it's like a nice triangular lattice like we expected.
[Slide 4] And then if we plot the band structure for this sort of device,
then we get two things, of course, the TM bands and the TE bands.
And you can see clearly that, in this particular case,
there's a large TM band gap, which is, of course,
different from the previous case of the array of a square rods
because this is an array of triangular lattice instead.
[Slide 5] And then we don't have a big band gap for a TE in fact.
And then if we visualize the fields that are being output using the so-called
band functions, which are invoked along with a TE or
TM run commands, in the bottom of the file.
Then, we actually can see what the different field profiles look like at
different k points, and we can actually visualize that using MPB data,
again, to correct the basis.
And then running h5 to ping to generate all these outputs.
And you can actually overlay the epsilon on top of field profile.
So you can see where exactly are the fields compared to the epsilon output.
Next time we'll talk more details about how we can use MPB
to do other types of calculations.
