On Board the $66 Million Quantum of Solace, the Most Luxurious James Bond-Inspired Yacht
A regular James Bond fan will go out to see the movies and, maybe, if he or she can afford it, buy related merchandise. But John Staluppi is no regular James Bond fan, and his Quantum of Solace superyacht is proof of that.
Some millionaire James Bond fans track down and buy rare Aston Martins, either those used in the film franchise or good replicas. For John Staluppi, car and business magnate, and an experienced yacht builder himself, a car won't suffice. If there's a record for the biggest James Bond fan in terms of how many yachts you own named after the installments in the series, he gets it. As of the time of press and over the course of three decades, Staluppi has owned over 21 yachts named after the films in the James Bond series. His most recent, Quantum of Solace, is now for sale, as he's decided he wants something different. Quantum of Solace is going for $66 million and was on display at the 2021 edition of the Monaco Yacht Show in September, in the hope of securing a buyer. It's yet to do that but, when it happens, the buyer will effectively be able to bring some of those James Bond fantasies to life. The one thing that sets Staluppi apart from other superyacht owners, aside from an almost unhealthy obsession with James Bond, is his perfectionist streak. The man knows what he wants from a boat and how to get it and, in the process, how to make it perfect. His second yacht, Octopussy, is officially the fastest one in the world, with a top speed of 61 mph (98 kph); the 2004 build, and his personal favorite, World Is Not Enough came close to taking that crown, with 77 mph (124 kph) on paper; sadly, it was never able to deliver on the promise due to technical issues.
Staluppi bought Quantum of Solace in 2019 after falling in love with it and upon hearing it was one of the four superyachts in the world to have a double-height atrium inside. Launched by Turquoise Yachts in 2012, the vessel had already gone through a drastic restyle and refit with H2 Yacht Design. So, its appearance was already more in keeping with the image of the famous spy, with the former ample curves on the superstructure replaced by sharp and more aggressive lines. Quantum of Solace provided Staluppi with something he was looking for at the time: more space, more stability, and a higher degree of comfort. You know, just in case you were wondering why he's selling it. At the time, it was the right choice, so Staluppi and his family spent weeks on end on board during the first round of lockdowns, enjoying themselves. Now that he's decided he wants something different – he's not saying what for the time being – someone else can have it. With a total length of 238 feet (72.6 meters) and four decks totaling a volume of 1,730 GT, Quantum of Solace offers accommodation for 12 guests in seven cabins, and 17 crew members in separate quarters. The guest cabins, including double rooms for children with attached nanny rooms, are all located on the main deck. The owner's suite is up top, and includes a giant master bathroom decked in marble and onyx, his and hers walk-in wardrobes, a private office, and private terrace. Furnishes are incredibly elegant and rich, as one would expect from a James Bond tribute yacht. Despite the association, there aren't that many 007 references onboard, so it's not like you're walking into a boy's shrine to the world-famous spy. But the air of sophistication and custom luxury prevails and is noticeable, from the art pieces throughout, to the rich combination of wood and plush carpets, backlit stone, glazing and chrome finishes.
Amenities include a spa below deck with a massage room and a gorgeous sauna, as well as a fold-out platform that bring guests directly to the waterline. Up on the sundeck is a 16-foot (488-cm) counter-flow pool and outdoor lounge area, a bar and a DJ booth, and a touch-and-go helipad for an EC 135 standard or similar. Matching tenders sit in the lateral garages, equipped with cranes and hydraulically activated doors for easy launching and retrieval from water. To these, you can add several formal and informal dining areas, both indoors and outside, a private cinema, a small concert hall, and more socializing areas than you can count on the fingers of both hands. Lloyd's-classed and MCA-compliant, Quantum of Solace is powered by twin 2,447 hp Caterpillar engines capable of taking it at a top speed of 17 knots, and a cruising speed of 15 knots. At 12 knots, it has a range of 7,000 nautical miles.

\section{Introduction}
All eigenstates are exponentially localized in one-dimensional disordered systems (1DDS)
with uncorrelated on-site disorder \cite{ishii73,abrahams79,lifshiz88}.
Recently, the study of delocalization phenomena
in the 1DDS  with long-range correlation
have been performed using analytical as well as numerical methods
\cite{yamada91,oliveira01,pinto04,esmailpour07,sales12,cheraghchi05,lazoa10,moura98,izrailev99,izrailev12}.
In particular,  many authors could numerically observe
the correlation-induced localization-delocalization transition (LDT)
in the 1D tight-binding model (TBM) by using the same
 potential sequences with power spectrum
$S(f) \sim 1/f^\alpha$($\alpha \geq 2$)
using Fourier filtering method (FFM),  where $f$ denotes frequency
\cite{moura98,izrailev99,zhang02,shima04,kaya07,kaya09,gong10,croy11,deng12,gong12,albrecht12}.

Very recently, Garcia and Cuevas
modeled the sequences with the power-law spectrum by Weierstrass function
with fractal dimension $D$ and studied the transition
 based on the differentiability of
the disorder potential as a necessary condition
for the delocalization \cite{garcia09,garcia10,petersen12,petersen13}.
As a result, they could numerically demonstrate that the LDT
takes place at the critical value $D_c=3/2$
by means of the distribution of the energy level-spacing
in the weak disorder limit.

In the previous paper \cite{yamada15}, we have numerically reported that
 the finite-size scaling analysis
for the normalized localization length (NLL)
at the band center ($E=0$)  suggests the existence
of the LDT around $D_c \simeq 3/2$ independent of the potential strength
in the  relatively weak disorder regime, as suggested by   Garcia and Cuevas.
On the other hand, in the relatively strong disorder regime,
the critical fractal dimension $D_c$ arrives at a smaller value than $3/2$
when varying the potential strength  \cite{yamada15}.
In addition, the existence of the power-law localized states has been
observed in the case of relatively weak disorder strength for $D \geq 3/2$,
which implies zero Lyapunov exponent.
Such a power-law localization have been also observed in off-diagonal disordered
systems and quantum   percolation systems \cite{xiong01,igor08,bellando14}.

What remains a question is the delocalization of the other energy states
of the TBM with the Weierstrass potential.
In this study, therefore, we numerically investigate the delocalized behavior
of the other energy states ($E \neq 0$) using the system size dependence of the NLL.
We demonstrate  the presence of the mobility edges and
the power-law localized behavior for $D \gtrsim 3/2$ in the weak disorder cases.
The critical value of $D$ decreases with increasing the disorder strength $W$
 in the strong disorder regime.

On the other hand,
the statistical properties of the individual NLL and Lyapunov exponent
have not beend studied in detail for the 1DDS with LDT, although the
anomalous fluctuation might be expexcted \cite{yamada91,pinto04}.
 With this in mind, we investigate here the statistical properties over
ensamble and are able to verify the presence of the anomalous fluctuation,
as well as to reveal the details of the systemsize dependence
by taking large system size and large ensamble size as much as possible.

This paper is organized as follows.
In the next section, we briefly introduce the 1DDS with the Weierstrass potential
and some  eigenstates.
In Sect.\ref{sect:main}, we present
global behavior of the $E-$dependence and $N-$dependence
in the LDT by the numerical calculation of the NLL.
In Sect.4,
we present statistical distribution and
convergence property of the individual NLL and Lyapunov exponent
with increasing the system size for the band edge state.
Summary and discussion  are presented in the last section.

\section{Model}
\label{sect:model}
We consider the one-dimensional tight-binding Hamiltonian
 describing single-particle electronic states  as
\begin{eqnarray}
  H= \sum_{n=1}^N V(n)C_n^{\dagger}C_n +  \sum_{n=1}^{N-1}C_{n}^{\dagger}C_{n+1} + H.C.,
\label{eq:tight-binding}
\end{eqnarray}
where $C_n^{\dagger}$($C_n$) is the creation (annihilation) operator for the
one-electron state at site $n$.
The $\{ V(n) \}_{n=0}^{N}$  and $W$ are the disordered on-site energy sequence and
the  strength, respectively.
The amplitude of the quantum state $|\Phi>$ is given by
$\phi(n) \equiv <\Phi|C_n^{\dagger}C_n|\Phi>$ in the site representation.
To model the correlated disorder potential
for $V(n)$($n\leq N$) in Eq.(\ref{eq:tight-binding}),
we use the following form:
\beq
V(n) = C \sum_{k=0}^{L} \frac{\sin(2\pi a^k n/N +\varphi_k)}{a^{(2-D)k} },
\label{eq:wei-pot}
\eeq
where $a$ is a constant value ($a>1$) related the scale-invariance
and $D$ is a fractal dimension ($1<D<2$).
 $\{ \varphi_k \}_{k=0}^L$ are random independent variables chosen in the interval $[0,2\pi]$.
$C$ is the normalization constant which is determined
by a condition
\beq
\sqrt{<V(n)^2>-<V(n)>^2}=1,
\label{eq:normalization}
\eeq
where $\langle...\rangle$ indicates the average over realization
of the phases in Eq.(\ref{eq:wei-pot}).
If we set $n/N=x$, $\varphi_k=0$,
the potential sequence becomes the "Weierstrass function" being continuous and
indifferentiable everywhere by taking
a continuous limit $N \to \infty$ and $L \to \infty$.
Therefore, the potential will be shortly transfered to as "Weierstrass potential" in this paper, and
we set $a=2$ and $L=50$ through this report
without loss of the generality and accuracy of the numerical calculation.
Figure \ref{fig:pot1} shows some potential landscapes.
We can see that the landscape becomes smooth as the fractal dimension $D$ decreasing.
Note that the
condition $\alpha \geq 2$ for the LDT
corresponds to a condition $ D \leq 3/2$
because the power spectrum $S(f)$ of the Weierstrass function
is empirically characterized by $S(f) \sim \frac{1}{f^{5-2D}}$.
The smoothness of the potential fluctuation can also induce the delocalization
of the quantum states, which property is directly related to analyticity of the
potential function in the continuum limit.

}
\label{fig:pot1}
\end{center}
\end{figure}

Garcia and Cuevas  \cite{garcia09,garcia10}
 have numerically found that LDT at $D_c=3/2$ for the sufficiently weak
disorder regime  by using the nearest-neighbor level-space distribution
of the energy spectrum.
It is useful to look at typical eigenstates directly to ratinalize the effects of the
fluctuation of the potential on the delocalization.
Some typical eigenstates are shown in Fig.\ref{fig:eig1}.
The state close to the band center as well as the one around band edge are localized
for $D=1.7$, while the state near band center is delocalized for $D=1.3$.
These features are consistent with our previous work \cite{yamada15}.
For small values of $L$ some typical potential landscapes and the eigenstates
are given in appendix \ref{app:A}.
In the next section, we investigate the energy dependence of the quantum states.

\section{Numerical Results of the normalized localization length}
\label{sect:main}
We define the normalized localization length (NLL),
\beq
\Lambda_N \equiv \frac{\xi(N)}{N},
\eeq
where $\xi(N)(=\langle \gamma_N \rangle^{-1})$ denotes the finite size localization length (LL),
and  the finite size Lyapunov exponent  $\gamma_N (N>>1)$ is defined by
\begin{eqnarray}
\gamma_N &=&  \frac{ \ln \left( |\phi(N)|^2 + |\phi(N+1)|^2 \right) }{2N},
\label{eq:gamma_n}
\end{eqnarray}
with the initial state $\phi(0)=\phi(1)=1$.
$\langle...\rangle$ denotes the ensemble average over different phases in Eq.(\ref{eq:wei-pot}).
We numerically calculate the $\gamma_N$
by using negative factor counting method \cite{dean72,ladik88}.
It is useful to study the LDT because $\Lambda_N$ decreases (increases) with the system size
$N$ for localized (extended) states,
and it becomes constant for the critical states.

In what follows, we investigate the NLL
 by changing the system size
for some typical values of the system parameters, $W$, $E$.
The typical size $N$ and ensemble size used
here are $N=2^{14} \sim 2^{21}$ and
$2^{11}\sim 2^{15}$,
respectively.
The robustness of the numerical
calculations has been confirmed in each case.

\subsection{Energy dependence:mobility edge}
Figure \ref{fig:fig3-d-dep} shows the energy dependence of the NLL
for the different system sizes ($N=2^{14} \sim 2^{21}$) with the fixed value $W=0.5$.
The $E-$dependence drops relatively smoothly down around $E \sim 0.7$
in the same way for all cases.
In the case of  $D=1.7$,  the NLL $\Lambda_N$ goes to zero as $N \to \infty$
in all energy regime.
In the cases of  $D=1.5$ and $D=1.3$,  the $\Lambda_N$ arrives at the finite values
greater than unity around the band center $|E| \lesssim 0.7$ as $N \to \infty$,
while in the region outside of the center $|E| \gtrsim 0.7$, $\Lambda_N$ decreases
zero.
Figure \ref{fig:fig3-d-dep-expand} shows detail of the $E-$dependence
of the NLL around $E=0.7$.
It is apparent that the states get localized in the regime $|E| \geq 0.7$.
$\Lambda_N$ exponentially decreases away from the edge $E \simeq 0.7$.
The results suggest the existence of the mobility edge for $D \leq 3/2$
in the thermodynamic limit, which is consistent with the result by Garcia and Cuevas.

Furthermore, it was found that the LDT depends on the value of disorder strength $W$
based on the result  in Ref.\cite{yamada15}.
Figure \ref{fig:fig3-w-dep} shows the $E-$dependence of the
 $\Lambda_N$ for some combinations of  the disorder strength $W$
and fractal dimension  $D$ at  the fixed system size of $N=2^{20}$.
In the relatively  strong disorder cases ($W \geq 0.5$),
the delocalized states appear around the band center  for  $D \leq 3/2$.
Figure \ref{fig:fig3-d-dep-1} shows the detail of the $E-$dependence
of $\Lambda_N$  in the case of $W=0.25$.
In the relatively  weak disorder case ($W =0.25$),
two peaks appear around $|E| \simeq 0.7$ when  $D=1.7$
although the states go to localized states with keeping the two-peaks
structure of the $E-$dependence  for $N \to \infty$,
as  shown in Fig.\ref{fig:fig3-d-dep-1}(a).
In the  case of  $D=3/2$,
 the double-peaks structure of the $E-$dependence remains
even for  $N \to \infty$,
as shown in Fig.\ref{fig:fig3-d-dep-1}(b).
The two peaks revealed ought to influence
 electronic transport and optical absorption.

\subsection{system size dependence:power-law localization}
Generally, the quantum states can be classified by the exponent $\delta$ of the
 $N-$dependence of the $\Lambda_N$
when it  behaves as,
\beq
 \Lambda_N \sim N^{\delta}.
\label{eq:delta}
\eeq
The exponent, $\delta \simeq 0$ for the extended states,
$-1< \delta < 0$ for the power-law localized states, and
$\delta \simeq -1$ for the exponentially localized states.
The states at the band center are more delocalized than the states away
from the band center.

Figure \ref{fig:n-dep-loclength}(a) and (b) show the system size dependence
of the NLL of a relatively strong disorder case ($W=0.75$) in the vicinity of
 the band center and edge, respectively.
It is found that the $N-$dependence changes the decreasing function with $\delta \simeq -1$
 to the constant function  $\delta=0$ as the fractal dimension decreases in the case (a).
It is found that the critical fractal dimension decreases with increasing
the disorder strength, which is  consistent with our previous result for $E \neq 0$.
On the other hand, the states near band edge are exponentially localized irrespectively
of the fractal dimension,  as seen in Fig.\ref{fig:n-dep-loclength} (b).

\begin{figure}[htbp]
\begin{center}
\includegraphics[width=8.5cm]{nLL-fig3.eps}
\caption{

(c)$W=0.5, E=0.48$, (d)$W=0.25, E=0.98$.
Note that the data plotted in double-logarithmic scale.
The ensemble size is $2^{12}$.
}
\label{fig:n-dep-loclength}
\end{center}
\end{figure}

Next, we have to pay attention to the delocalization of the states
with energy away from $E=0$
in the relatively weak disorder cases ($W \leqq 0.5$),
as given in Fig.\ref{fig:n-dep-loclength} (c) and (d).
Note that the $N-$dependence of the NLL becomes independent of the system size
for $D \leq 3/2$ in agreement with the extended nature of the states.
The fact that the slopes of the straight lines in the log-log plot
are  $-1 < \delta <0$ strongly suggests the power-law localization of the states.
As a result  it is suggested that
the LDT takes place around the transition point $D_c=3/2$ irrespectively of the disorder strength
in relatively weak disorder regime $W \leqq 0.5$,
as shown in Ref.\cite{yamada15}.
Exponential localization takes place for $D > 3/2$, while the behavior specific for the critical point
arises in the whole range of $1< D \leq D_c$.
In the case of $W << 1$,
the latter situation corresponds to the localization with the divergent localization length
even for $D > 3/2$
and probably should be interpreted as the power-law localization.

\section{Distribution of individual normalized localization length
and Lyapunov exponent}
\label{sect:distribution}
In this section, we discuss the statistical property of
the distribution of  individual NLL and Lyapunov exponent at $E=1.0$
that is expected to correpond to a localized state.

First,  we define the individual NLL
$\Lambda_N^{(s)} \equiv 1/(N\gamma_N^{(s)})$, where $\gamma_N^{(s)}$
is Lyapunov exponent of a finite system with system size $N$ and
the suffix $s$ run for each sample.
Note that the mean value $\langle \Lambda_N^{(s)} \rangle$ satisfies
inequality $\Lambda_N  < \langle \Lambda_N^{(s)} \rangle$
because $\langle \gamma_N \rangle > 1/\langle  1/\gamma_N \rangle$.
Figure \ref{fig:dise10} shows the histograms of the distribution of
$\Lambda_N^{(s)}$ around band edge ($E=1.0$) over $2^{15}$ samples.
In the case of $D=1.6$,
 the asymptotic behavior of the distribution of $\Lambda_N^{(s)}$
gradually moves to the origin position with increasing system size $N$.
On the other hand,
it is found that in the case of $D=1.5$,
 it converges the distribution form with power-law tail.
The $N-$dependence of the mean value $\langle \Lambda_N^{(s)} \rangle$ and the standard deviation
$\sigma_{\Lambda}$ are shown in Fig.\ref{fig:n-dep-avsd-e10}.
The  $N-$dependence is unstable and a
 clear difference does not appear between the cases of $D=1.6$ and $D=1.5$,
different from cases of $\Lambda_N$ in the last section.

\begin{figure}[htbp]

The details behavior around $\Lambda_N^{(s)} \sim 0$ is shown
in each inset in the log-log plot.
and the mesh of the horizontal line is $5 \times 10^{-2}$.

for fractal dimension $D=1.4,1.5,1.6$.
}
\label{fig:n-dep-avsd-e10}
\end{center}
\end{figure}

In localized regime such as $D=1.6$ and $D=1.5$ around the band edge,
Lyapunov exponent $\gamma_N$ is better
than $\Lambda_N^{(s)}$ to study the localization property.
Fig.\ref{fig:dis-lyap-e10} shows the histogram of the {distribution
of Lyapunov exponents around band edge ($E=1.0$) over $2^{15}$ samples.
Aa a result the two kinds of distribution coexist.
One of the two peaks  around  $\gamma_N \simeq 0 $ corresponds to
the extended states or power-law localized states.
Fig.\ref{fig:n-dep-lyap-e10} shows $N-$dependence of
the mean value $\langle \gamma_N \rangle$ and standard deviation
$\sigma_{\gamma_N}$ of the distribution for some cases.
We estimate the Lyapunov exponent $\gamma_\infty$ for
$N \to \infty$ by fitting the relation,
\beq
 \langle \gamma_N \rangle = c_1 N^{-\alpha} + \gamma_\infty,
\label{eq:fitting}
\eeq
for all the cases in Fig.\ref{fig:n-dep-lyap-e10}(a).
The estimated parameters are shown in Fig.\ref{fig:alpha-gamma-e10}.
As a result, at least,   the Lyapunov exponent becomes zero,  $\gamma_\infty  \simeq 0$,
for $D \leq 1.7$ at the band edge ($E=1.0$), which is  consistent with
power-law localization in the last section.

The distribution form tends to be anomalous  around the LDT
and the ensemble-averaged value of the finite system size becomes unstable.
Accordingly, it is important to investigate the statistical property of the distribution
around the transition point because it is sensitive to the difference of the definition,
as seen in this section.

\section{Summary and discussion}
\label{sect:summary}
In summary, we have numerically studied the nature of  LDT
 in 1DDS with fractal disorder generated by Weirstrasse function.
We have explicitly shown some basic features of the system.
We used the normalized localization length defined by the Lyapunov exponent to
investigate the delocalized behavior of the wavefunctions for the entire energy region.
The results suggest that in the  weak disorder cases
a metallic band of extended states in the finite region of the energy
 exists for $D \simeq 3/2$.
In addition, the power-law localized states have been observed for $D \geq 3/2$,
with decreasing the fractal dimension $D$ in the cases.
On the other hand, the  $N-$dependence of the NLL suggests that
for the strong  disorder cases all the states are exponentially localized
even for $1.3< D \lesssim 1.5$,
which is consistent with the finding of Ref.\cite{yamada15}.
We have revealed the anomalous distribution of the individual NLL, as
well as found that the asymptotic behaviour of the ensemble-average for
Lyapunov exponent $\langle \gamma_N \rangle$ consists in that the latter goes to zero with
increasing the system's size
for $D  \leq 1.7$.

The same properties as in the 1D electronic system given in this paper
are also expected for the delocalization of acoustic wave \cite{esmailpour08,moura11,moura15},
electromagnetic wave  \cite{sheng90,diaz05} and seismic wave \cite{shahbaz05}
in one-dimensional layered media with fractal disorder.
We expect that the present work would stimulate further studies of
the localization-delocalization transition in 1DDS.

New report highlights political risk in Canada
Within international circles, Canada used to frequently get a pat on the back for its peacekeeping efforts.
To many foreign observers, we were just a bunch of friendly loggers, fishermen and miners, who were pleasant to each other and proud of our massive country overflowing with natural resources.
How perceptions – and reality – have changed.
Eurasia Group, a New York-based consultant focused on political risk, recently published its "Top Risks of 2023." It's a stark look in the mirror for Canadians.
Not just any mirror, but unfortunately, one of those fun house mirrors at carnivals that make you out to be scary monsters.
The report summarizes the leading threats to global stability. It includes some obvious risks, like Russia's invasion of Ukraine and Iran's ruthless suppression of political dissent.
However, the consultant singled out Canada, among a few other countries, for a special one-page report.
Not because Canada represents a global threat, but rather to point out that troubling things are happening in our politics and society that others are starting to pay attention to.
"Canada has long seemed impervious to the political divisions and dysfunction apparent across the border in the United States. But the trucker convoy that occupied the capital of Ottawa last year—ostensibly protesting Covid-19 vaccination mandates—was a big indication that something had changed," the reads the report.
The authors predict that 2023 will see deepening political polarization in Canada and growing regional divisions – think Alberta under the leadership of Premier Danielle Smith and her antagonistic relationship with Ottawa.
Inflation, rising interest rates, a sluggish economy and increasing unemployment, will "put fiscal pressures on indebted households, businesses, and governments."
Canada is not alone in these economic challenges. But the report says that two factors will make things worse in our country.
First, hyper-polarized political parties divided along regional lines "will amplify rural-urban and eastern-western tensions for political gain."
Second, there's a declining trust in traditional media, massive exposure to US politics, cable news and talk radio, and a growing network of cross-border special interest groups linking US and Canadian far-right and far-left organizations.
The report highlights rising populism in Canada that threatens to splinter the confederation further.
"… Canada's combative partisan and regional politics are poised to take a turn for the worse," according to the report, adding that healthcare funding, federal immigration, energy, and climate change policies will be political flashpoints.
"Canada and the US are growing closer, but it's less about alignment between Ottawa and Washington than cross-border alliances between sub-national governments and politicians of the same political stripe."
They even go so far as to point out that politics in Alberta and Texas "are increasingly alike" Links between extremists here and in the US will get stronger in the coming year, leading to an increase in civil disobedience, disruption, protest and even violence in Canada.
VanIsle isn't immune to right-wing populism. A large caravan of trucks from the Island is rumoured to be ready to roll if Convoy 2.0 goes ahead in Ottawa, Counts or Manitoba.
The report doesn't make for a light, feel-good read to bring in the New Year.
In many ways, it reflects what many of us already know. But, unfortunately, Canada's politics have gotten much uglier in the past few years. Too many people are getting their "news" from social media. Too many leaders would rather traffic in fear, blowing up bridges instead of building them.
Still, it's fascinating to look through the same window through which some others are viewing us these days. It doesn't look good.
Take the following warning from the report authors.
"When the US sneezes, Canada catches a cold. So watch out for sniffles north of the border in 2023."

Boosting Immunity Through Herbs and Nutrition
2 months ago Kelly L. Gorsuch
Dependent on the hemisphere you are living in, you may possibly be moving into either…
Dependent on the hemisphere you are living in, you may possibly be moving into either winter season or summertime. A lot of pathogens grow to be a lot more commonplace in wintertime, with the chilly and flu remaining widespread examples. Illness can arise at any time, on the other hand, and individuals with a suppressed immune technique, this sort of as the elderly, the highly pressured, and even all those who training at a high depth on a normal foundation, might be more vulnerable. There are many organic herbs and nutrients that may well help immune purpose during these occasions and give your overall body all the things it desires to stay at whole potential so you can carry on your conditioning journey unimpeded.
Some Notes on the Immune Program
Innate compared to Adaptive Immune Response
The innate immune reaction is the very initially line of defense when an intruder tends to make make contact with with the immune technique. It could be a dangerous organism (microorganisms or virus, for case in point) or a food items ingredient that will get by means of the intestine wall as part of leaky gut. The immune program functions quickly to eliminate the intruder in just four days of acquiring contaminated. At the exact time, the immune cells also mail chemical alerts to begin recruiting much more forces to arrive and help with the invasion.
The chemical signaling molecules generated for the duration of this initial line of defense include histamine, bradykinin, serotonin, leukotrienes, and prostaglandins. They all make irritation, which is what creates redness, inflammation, heat, and ache. Believe of the inflammation inside your nose and the increased mucous production when you get a chilly or the fever you get with viral infections these kinds of as the flu. These inflammatory products and solutions are what make you feel depressing when you are unwell, not the micro organism or the virus alone. Micro organism and viruses simply act as the set off.
Soon after about 4 times, the adaptive immune reaction kicks in. This is the 2nd line of protection and a bit a lot more specialised. The immune procedure adapts to come to be extra distinct to the pathogen intruder. At times, having said that, issues can go mistaken and other cells get in the firing line when pathogens are getting killed, which is how autoimmune condition can start. The adaptive immune reaction employs T and B lymphocytes as part of the immune method and can clone them very quickly when an infection is present. Each new cell that is made will be precisely the same as the cell it came from and will target the exact very same pathogen. So, if you get the flu, your immune procedure will make millions of T and B lymphocytes that will especially get rid of the flu virus only.
Humoral vs . Cellular Immunity
The immune technique works by using two adaptive mechanisms to secure from international invaders, namely cellular and humoral immunity. Humoral immunity is all about building antibodies, whilst mobile immunity is about destroying contaminated cells. Both of those mechanisms generate swelling that requirements to be managed. Serious swelling that is left uncontrolled can damage balanced cells and contribute to larger health difficulties than just obtaining an an infection.
Humoral immunity takes place when the physique can make antibodies in opposition to anything that is outside the cells and relocating around freely in bodily fluids these as blood or mucous. T-helper cells enable the B cells adjust into a lot more unique cells that then bind to antigens on the outdoors of the invader organisms and neutralize them through a method termed phagocytosis, for the duration of which B cells are cloned with a memory of the distinct antigen on the damaging organism. It can be like taking a mug shot or fingerprints. The memory B cells remain inactive but dangle close to and will instantly identify the organism if they come upon it again, hastening the approach of reducing the risk the subsequent time close to.
Mobile immunity becomes involved when the pathogenic organisms are previously inside the cells. Viruses can't make you sick except they get inside of your cells in which they can replicate. The cell-mediated reaction is the most powerful response when it will come to eradicating virus-contaminated cells. T-helper cells release inflammatory variables that assistance the T cells transform into cytotoxic T cells, which can then destroy the infected mobile by triggering apoptosis, or mobile-suicide.
It is significant to guidance each humoral and mobile immunity in the adaptive response so the immune method can get rid of contaminated cells, but at the exact time you want to make guaranteed that the adaptive responses do not go into overdrive and cause enormous inflammation and cellular damage. It is all about maintaining balance.
Ahead of we get to our best five herbs for bolstering the immune technique, listed here are a handful of essential definitions:
Immunostimulatory describes one thing that stimulates the immune program by activating it or increasing its exercise. Stimulation indicates a lot more B and T lymphocytes and much more immune cells, but also extra inflammation.
Immunosuppression is a thing that prevents the immune procedure from reacting to antigens and launching an attack. From time to time this is required, such as in the scenario of organ transplants, exactly where you never want the immune process to attack the new organs.
Immunomodulation is modulation of the immune technique, bringing it to again to usual ranges in which it self-regulates. In essence, one thing that is immunomodulatory will tranquil down an overactive immune system, defending you from your personal defense mechanisms devoid of suppressing an underactive immune process. In other terms, it presents stability.
5 Common Herbs That Are Very good for the Immune Process
1. Ganoderma Lucidum (Reishi Mushroom)
Reishi, or lingzhi, mushroom, is a substantial dim mushroom with a glossy exterior and a woody texture that has been identified as, "the mushroom of immortality," "the 10,000-year mushroom," and "the mushroom of non secular potency." It usually grows on tree stumps and the base of trees these types of as the maple, but only on 2-3 trees out of 10,000, making it a very unusual obtain in the wild.
It is quick to recognize how this mushroom has arrive to be made use of in traditional tactics as it has about 400 bioactive compounds, with the polysaccharides and triterpenes in all probability the most investigated of them. Reishi is regarded to guidance the two the innate and adaptive immune responses. It has the likely to improve those people initial-line defenses all the way by way of to the adaptive responses though even now running the body's response to strain.*
Ganoderma lucidum is discovered in pill, capsule, powder, and liquid forms as a supplement, but never forget that it is a food. To get all the goodness for your immune program out of the mushrooms, you have to break their mobile partitions, which signifies cooking them. It's the very same for dietary supplements. Just drying the mushrooms and powdering them to use in health supplements may not have the health advantages reishi is recognized for. The mushroom ought to be processed making use of certain procedures to be certain a higher-good quality nutritional supplement that actually functions.
You can uncover several recipes on the net for preparing Ganoderma lucidum, so have enjoyable experimenting.
2. Artemisia Annua (Sweet Wormwood)
Sweet wormwood, also identified as Chinese wormwood, or qing hao, between other names, is an historic herb that has standard utilizes dating again as far as 168 B.C. It has been employed for more than 2,000 yrs in Chinese lifestyle. Take note that not all Artemisia species have the same action. The reference right here is particularly to the Artemisia annua variety.
Artemisia annua has a wonderful name in modulating the immune system, that means that it balances immune responses and helps prevent overstimulation and too much swelling. Its actions are extremely a lot directed at the adaptive immunity responses that commonly kick in 4 times right after you get an an infection.*
Wormwood has a bitter flavor and is used to brew liqueurs and other alcoholic drinks.
3. Ursolic Acid
Technically, ursolic acid is not an herb but an lively compound observed in apple peel and other fruit peels, rosemary, thyme, elder flower, and other herbs and crops.
Ursolic acid has been proven to enhance interferon-gamma (IFN-g) manufacturing, which features in the mobile immune reaction in adaptive immunity.[1] IFN-g is an vital immune element that switches on several other genes and proteins that support the immune process operate at entire capability.*
Ursolic acid seems to have a solid system for controlling the inflammatory reaction, which could be advantageous in supporting your entire body properly answer to worry and intense exercise.[2] You would most likely have to consume a great deal of the over-outlined foods to get the quantity of ursolic acid utilised in these scientific studies, but however, it is food items and meals is good.*
4. Curcuma Longa (Turmeric Root)
Turmeric is perfectly-recognised as the orange-yellow spice made use of in curry powder, but turmeric, or curcumin, supplements are also among the the top rated-promoting organic dietary supplements in the U.S. Curcumin is very best acknowledged for its affiliation with a lessened inflammatory reaction to exercise, with many folks using it for restoration from delayed-onset muscle mass soreness. In the past two a long time, however, study has revealed that curcumin is also a impressive immunomodulator. It precisely modulates the activation of T cells, B cells, and several other immune cells, all of the typical players that you come across in both equally innate and adaptive immune responses.[3]*
Quite a few curcuma longa supplements on the marketplace concentration on bioavailability and absorption of turmeric by adding black pepper or modifying turmeric into liposomal or nanoparticle varieties however, the advantages to the immune procedure may come much more from how your gut micro organism and turmeric interact inside the digestive tracts as opposed to absorption into the bloodstream. Just one review describes turmeric as having "prebiotic-like" results on intestine microorganisms without staying a prebiotic since it are not able to offer energy for intestine micro organism.[4] In point, it looks to have far more of a modbiotic outcome by transforming the composition of the intestine and growing the richness of bacterial species.*
The intestine wall has 70 p.c of the cells that make up your immune procedure, and a wholesome gut microbiome properties bacterial species that have a host of beneficial results. Compounds manufactured by intestine germs via the processing of turmeric and other herbs can result in the release of signaling molecules in the bloodstream that deliver systemic benefits. Which is the way a good deal of herbs and foodstuff support the immune program.*
5. Boswellia Serrata
Boswellia serrata, or Indian frankincense, is a really underrated herb. Technically talking, it is not an herb but a resin from a substantial-sized branching tree of the household Burseraceae that grows in the dry mountainous regions of India. Its two primary lively components are 11-keto-beta-boswellic acid (KBA) and acetyl-11-keto-beta-boswellic acid, and it has been employed ordinarily in supporting balanced immune and inflammatory action, primarily as a 5-lipoxygenase (5-LOX) inhibitor.[5] *
But Boswellia serrata is a lot more than just an anti-inflammatory. As section of the adaptive immune response, at lower doses it would seem to enhance antibody manufacturing as portion of humoral immunity and also boost B and T lymphocyte production as aspect of cellular immunity.[6] This is how Boswellia serrata, as an immunomodulator, can enhance the immune reaction when it is needed most, as perfectly as enable continue to keep your inflammatory responses from obtaining out of control.*
Boswellia serrata is really unpleasant to acquire as a liquid, and it will really feel like it is caught on your palate because of to its significant resin written content. Definitely considerably improved in a capsule sort.

Gang of thieves targets women in Arapahoe County
Investigators say the Felony Lane Gang is back in Arapahoe County, and they are investigating several potentially-connected crimes.
By: Jaclyn Allen
CENTENNIAL, Colo. -- If you think you're just going to run inside quickly and leave your purse in the car, think again.
That's the warning from the Arapahoe County Sheriff's Office.
Lori Kaupp says she was dropping of her daughter at a Centennial daycare center in July when the thieves broke into her locked car.
"They shoved something into the keyhole and broke off part of the door handle," said Kaupp. "Somehow that disabled the alarm. I was gone five minutes. That's how quick it was."
By the time she got back, the thieves had taken off with her purse and checkbook.
Arapahoe County released photos of the woman wanted in connection with trying to cash the checks at local banks, and Kaupp has a warning for women.
"Obviously, as we all know, don't leave your purse in your car and really pay attention to your surroundings," said Kaupp.
The Felony Lane Gang has been operating for years nationally, getting its name because members use the far lane in bank drive-thrus so that the teller can't see them as well.
"We don't know if they're all connected, but we know it's the same M.O.," said Julie Brooks, a spokeswoman with the Arapahoe County Sheriff's Office. "They break into cars, steal checkbooks and cash checks at banks using stolen ID's they got from other cars. They are very organized."

Q: Cardinality estimation on tables with large cardinality variance between keys Context
I have stumbled on an issue in SQL Azure where the Sort-operator is spilling over into TempDB due to poor row estimates.

*

*We are querying a master table that is joined with a number of detail tables

*The table uses a TenantId-column to partition the table per tenant

*Some tenants have 10,000s of rows, some only 100s.

*There is a row-level security policy in place that adds a FILTER PREDICATE to all queries on the aforementioned TenantId

*Queries are generated by Entity-Framework in a .NET application

*All index statistics are up-to-date

*All detail tables rows are retrieved via Index Seeks

The issue
The Cardinality Estimator is yielding very low estimates due to the large variance of rowcounts between tenants. This combined with two inner joins reducing the estimates even further, makes it so that a query that actually yields 3600 rows, was only expected to yield 3. That's 3 orders of magnitude off.
What have I tried?

*

*Defined Filtered Statistics for those key values that yield a high number of rows, as an extra hint to the CE.

*Ran into limitations in dealing with parameterized queries. The OPTION ( RECOMPILE ) works for some predicates, but not for the TenantId which is injected via the aforementioned security policy.

*Inlined the filter predicate so we are effectively filtering on the same column twice works, but seems ... redundant to say the least

*Changing the INNER JOINs to LEFT OUTER JOINs improves the bad join estimates but since we use Entity-Framework I would prefer a solution which does not require changing the query. Note: obviously if the only way is to rewrite the query, then that is the route we will go.

Other ideas

*

*I have toyed with the idea to just add a dummy tenant with 100k records to offset the estimations so that row estimates are at least large enough for the largest real tenant, but this would make us over estimate for the small ones.

What am I looking for?

*

*Am I doing something wrong - did I paint myself into a corner?

*Are there alternatives I could consider?

I welcome any ideas you might have, Thanks!

The sort operator is there for paging. I don't actually want to retrieve all the rows. So in short, the sort needs to happen in the db (not in the app).
Also, to be clear, the issue here is not the EF generated query. It is a simple query with a number of INNER/LEFT OUTER joins and a few filter predicates. It is not the typical 5000-line SQL statement that is legible to no one.
It seems the details lookups are done via hash match which loses the index's sort ordering. Also the column that is ordered on is user defined, and changes depending on the use-case, so to avoid the sort I would need an index per column they could possibly sort on.
Additional information
The Row-level security policy
CREATE FUNCTION Security.myAccessPredicate(@TenantId nvarchar(128))
    RETURNS TABLE WITH SCHEMABINDING
    AS
    RETURN SELECT 1 AS accessResult
    WHERE @TenantId = CAST(SESSION_CONTEXT(N'TenantId') AS nvarchar(128))
    OR CAST(SESSION_CONTEXT(N'TenantId') AS nvarchar(128)) LIKE 'ReservedTenantIdForCrossTenantOperations'");

CREATE SECURITY POLICY Security.mySecurityPolicy
    ADD FILTER PREDICATE Security.myAccessPredicate(TenantId) ON Schema1.Object10,
    ADD BLOCK PREDICATE Security.myAccessPredicate(TenantId) ON Schema1.Object10,
    ... And all the other tables

The Master table index DDL
CREATE NONCLUSTERED INDEX [IX_Object10] ON Schema1.Object10
(
    [TenantId] ASC,
    [Discriminator] ASC,
    [IsDeleted] ASC,
    [CreatedAt] ASC
)

    WHERE (Object2.Discriminator = N'SomeCategory') AND (0 = Object2.IsDeleted)
)  AS Object1
ORDER BY Object1.CreatedAt DESC
OFFSET ? ROWS FETCH NEXT ? ROWS ONLY

The query plan (anonymized) : https://pastebin.com/msjPQ6Vs
Estimated

Actuals

The master table (Schema1.Object10 AS Object2) returns 3600+ actual rows from the index seek, but CE estimates 381 rows. Then the two inner joins to Schema1.Object11 and Schema1.Object12 further reduce the estimate to 2.9 estimated number of rows. This makes no sense to me. The inner joins happen on non-null id columns with foreign key constraints, so it should be impossible to not find a match.
The sort operator tooltip:

Actual Timings, whereas the cumulative time before the sort operator was 16ms

A: Sorry if I missed this in my quick read through..... But have you tried enabling Legacy Cardinality Estimation on the Database?
I'm a ManyHatAdmin for an Application that has the ability to generate SQL queries that run against large DBs on the fly, often with INNER JOINS. We found that post SQL 2016 (when CE underwent a number of changes) that certain queries would run far slower because of the new CE. The solution we found was to set Legacy Cardinality Estimation on 'ON' at the database level.
I beleive it can also be activated for a specifc query only using the ('FORCE_LEGACY_CARDINALITY_ESTIMATION') Query Hint.

Q: How to Customize Xamarin Forms ListView SelectedItem ViewCell Visibility? In Xamarin Forms XAML, I want to hide part of ViewCell if it is not selected.
For example the second label with text="Show only if selected".
How to do that using MVVM without code behind?
<ListView x:Name="listView">
     <ListView.ItemTemplate>
         <DataTemplate>
             <ViewCell>
                 <StackLayout>
                     <Label Text="Always Show it"/>
                     <Label Text="Show only if selected" IsVisible={Binding somewhere?}/>
                 </StackLayout>
             </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

A: Here is one possible MVVM approach, which involve no code-behind.
ViewModels
Add a property* in your ListView item viewmodel to store information that indicate whether the item is currently selected :
public class ItemViewModel : INotifyPropertyChanged
{
    ......

    private bool _isSelected;
    public bool IsSelected
    {
        get { return _isSelected; }
        set
        {
            if(_selectedItem != value)
            {
                _isSelected = value;
                OnPropertyChanged();
            }
        }
    }
}

Then in the page's viewmodel, have another property* for binding ListView's SelectedItem, in the setter of which you can setup IsSelected value accordingly :
private ItemViewModel _selectedItem;
public ItemViewModel SelectedItem
{
    get { return _selectedItem; }
    set
    {
        if(_selectedItem != value)
        {
            //update previously selected item, if any :
            if(_selectedItem != null) _selectedItem.IsSelected = false;

            //update currently selected item :
            value.IsSelected = true;

            _selectedItem = value;
            OnPropertyChanged();
        }
    }
}

View
Bind IsVisible property to the ListView item viewmodel :
<Label Text="Show only if selected" IsVisible="{Binding IsSelected}"/>

*) The property needs to be a public property, in a class that implements INotifyPropertyChanged or inherits other class that implements it, and the property raises property-changed notification accordingly, as exemplified in the above snippets.

For reference:

*

*Xamarin official guide: Part 5. From Data Bindings to MVVM

*Complete example of the above codes in Gist

A: Each item in your listview needs to have a "IsSelected" bindable property. Then on your listviews ItemSelected event get the item and set is IsSelected to true. Just make sure you keep a reference the the currently selected item so that you can set the IsSelected to false on it one a new selected item is pressed. It should look something like this.
    MyItem _currentlySelectedItem;
    void OnSelection (object sender, SelectedItemChangedEventArgs e)
    {
      if (e.SelectedItem == null) {
        _currentlySelectedItem = null;
        return; //ItemSelected is called on deselection, which results in SelectedItem being set to null
      }
      var selectedItem = e.SelectedItem as MyItem;
      selectedItem .IsSelected= true;
     _currentlySelectedItem.IsSelected= false; /// Make sure to check for null
     _currentlySelectedItem = selectedItem ;
    }
