Joe's Crab Shack Is "100% Shore" about its New Direction
Toby Weber April 30, 2013
A new brand position and new prototype that focuses on back-of-house efficiency and food safety are redefining this 22-year-old seafood chain.
Some Joe's units have an enclosed patio, complete with picnic tables, reminiscent of the seaside crab house experience the chain wants to offer to its customers.For Houston-based Joe's Crab Shack, the past 12 months have been among the most active in the chain's history. In May of last year, Joe's parent company, Ignite Restaurant Group, completed its initial public offering. In November, Joe's chose a new advertising agency of record, McCann Erickson New York; and in February, the chain took on a new president and a new brand position.
Of course, to the average Joe's customer the new brand position — "100% Shore" — and all that comes along with it are what matter most.
The original Joe's founders got their inspiration for the chain after dining at seaside crab houses during a visit to Galveston, Texas. Though the concept has changed hands in the 22 years since its launch, this new campaign represents a return to that beginning. "'100% Shore' is really about us getting back to our roots as a crab shack, a Gulf Coast company," says Jim Mazany, the new president of Joe's. "It's paying homage to where we come from, from a brand perspective. We're an American crab house with locations across the United States."
The campaign's first commercials, which began airing in February, feature scenes from mom-and-pop seaside crab houses — a handful of seasoning tossed into a pot full of steaming crabs, happy customers sitting at picnic tables while cracking open crab legs — with a narrator tying the seaside crab shack experience to dining at Joe's.
According to Mazany, with the campaign, Joe's is repositioning how customers approach the brand. By embracing its crab shack roots, the chain wants customers to think of it as a place where they can come for a unique seafood experience at any time, replacing the perception of Joe's as a special occasion restaurant. This new brand position has more behind it than just commercials, though. In 2010, Joe's launched a new prototype restaurant that, while developed before "100% Shore," clearly aligns with the new ad campaign.
Take the new front-of-the-house design: In Joe's legacy system, the bar area was placed in the restaurant's corner, but new Joe's units feature the bar front and center, embracing the natural pairing of crab legs and cold beer one would find at a seaside crab house. This new design, says Mazany, places the walk-in cooler that holds kegs of beer directly behind the bar, allowing the restaurant to improve its drink offerings. "We don't have to use a glycol system. We draw right out of the kegs. We're able to serve beer at the optimum temperature, but it also has the shortest run you could imagine, just three to four feet," he says.
Another touch that fits in with the "100% Shore" campaign is the new dining tables Joe's has rolled out. Replacing basic acrylic tables are tables with nautical maps of the area where the unit is located. The maps, Mazany says, reinforce the chain's crab house roots while serving as a talking point for employees and a conversation starter for guests.
Joe's most obvious embrace of its crab shack heritage, though, comes in the form of something rarely seen in customer dining areas: handwashing sinks. These large stainless steel sinks, with metal grates below and tile walls behind, are located at several points in the front of the house and allow patrons to easily clean up both before cracking into a bucket of crabs and afterward — when they're done with their meal and all the steam, juices and bits of shell that come with it.
The handwashing sinks, along with other touches like the special tools for opening crab, and buckets at each table for disposing of bits of shell and used napkins, offers Joe's customers more interactive meal experiences than they'd find at most casual restaurant chains, says Mazany. "They'll walk away with a memorable, unique experience that they won't be able to get anywhere else."
FOH Charm, BOH Efficiency
Of course, any significant restaurant redesign involves not just changes to the front of the house, but to the back as well, where new equipment and processes can be implemented to improve multiple aspects of the operation. At Joe's one of the most significant changes in the back of the house involves how food is received, stored and prepped.
Under Joe's legacy system, crab dishes like steampots — large pots filled with ingredients like crab legs, potatoes, corn, lobster and mussels — were prepared at a standard prep station. In this process, crabs, which were received refrigerated after they had been steamed, were placed on ice, and kitchen staff would portion them along with other ingredients into small plastic nets for rethermalizing once ordered. In the new prototype, this prep work takes place not in the kitchen, but in a walk-in refrigerated prep room, a change that Mazany says "just screams food safety."
Inspired by butcher shops and steak houses that cut meat in a temperature-controlled space, the refrigerated prep room includes a three-compartment sink for washing brine off crabs and cleaning vegetables, along with worktables where BOH team members use vegetable peelers to nick the spines off crabs and portion various seafood dishes. Staff place the steampots in color-coded plastic nets; these identify the exact dish, sealed by color-coded zip ties that also tell the day the dish was prepped.
The prep room itself is part of a larger walk-in system. While the exact layout varies from unit to unit, typically this walk-in system is L-shaped, with the larger portion of the L sharing a wall with the hot cooking line. Each component of this series of walk-ins is separated by doors and air curtains that activate when a door opens, and each has its own cooling system.
At one end of this line of walk-ins sits the freezer. Here, depending on the layout of the individual unit, deliveries are received from refrigerated trucks, reducing to mere seconds the amount of time perishable food is unrefrigerated. From there, food is distributed to its proper storage area.

There are plenty of places in the diagnostic process where things can go wrong. But radiology is a frequent source of medical error that is ripe for reform, according to a new report.
Coverys, a Boston-based medical liability insurer, reviewed more than 10,600 malpractice claims from between 2013 and 2017 and found that nearly 600 named a radiologist explicitly. These cases often related to significant patient harm and delayed diagnosis of serious conditions, according to the group's report.
About 80% of claims involving radiology were related to misinterpretation of diagnostic reports, according to the study. There is a lot of variability in how different radiologists may read a report, which leaves the door wide open for a mistake, Robert Hanscom, vice president of business analytics at Coverys, said in an interview with FierceHealthcare.
Peer review is a key strategy, Hanscom said, especially since the interpretation stage is the riskiest. Getting a second opinion can ensure that nothing on a test result is missed and can prevent communication gaps, such as getting crucial information to the physician that can best use it.
It doesn't take much for one of these communications breakdowns to occur, Hanscom said. For example, if a patient were to undergo a chest x-ray in the emergency department that shows abnormal spotting, those results may not be taken care of if the only doctors who are made aware are in the ER. If that information doesn't make it back to the primary care doctor or family doctor, that patient will learn too late that he or she has lung cancer.
Providers have begun to make strides on some of Coverys' suggestions, however, Hanscom said. For example, many hospitals are building templates for radiology reports, he said—though the next step to really prevent patient harm would be to standardize those forms nationwide.
More providers are also working toward building clear guidelines on when second opinions are necessary, he said. But addressing the variability of interpretation still requires a lot of work.
"Radiology has to continue to really roll up their sleeves and figure out how they reduce that variation," Hanscom said.

I've been chilling on the East Coast for the last few weeks and LOVIN' it! I promptly passed out my business cards to all of my parent's friends and this weekend it paid off. I made a happy mother's day cake for a friend of ours. She wanted all buttercream, which was fun for me. I have been working with fondant so much that I have not done a buttercream cake in a while. It was chocolate with chocolate mousse and iced with vanilla buttercream. Real yummy. I have to admit that the quality of my cakes has really been getting pretty good if I do say so myself.
I went to NYC a days ago and we went to a wonderful store called NY Cake. It was a VERY fun few hours. They had EVERYTHING that I have only seen online including lots of edible glitters and Ateco cutters and even... LACE FONDANT MOLDS!!! I didn't buy one of those, but they were SO much fun to look at. I have dreamed of these things and it was fun to finally hold one. They even have a website so I would check it out if I were you.
Are you seeing how SMOOTH that buttercream is???
Dude good roses! And so smooth!
Wow! How did you get the buttercream so smooth?

\section{Introduction}

Quantum steering describes the ability of one observer to nonlocally
affect the other observer's state through local measurements, which
was first noted by Einstein, Podolsky and Rosen (EPR) for arguing
the completeness of quantum mechanics in 1935 \cite{ein}, and later
introduced by Schr\"{o}dinger in response to the well-known EPR
paradox\cite{sch}. After being formalized by Wiseman et al. with a
local hidden variable (LHV)-local hidden state model in 2007
\cite{wis}, quantum steering has attracted increasing attention and
been explored widely. Steerable states were shown to be advantageous
for tasks involving secure quantum teleportation \cite{rei, ros},
quantum secret sharing \cite{walk, kog}, one-sided
device-independent quantum key distribution \cite{bra} and channel
discrimination \cite{pia}.

Quantum steering is one form of quantum correlations intermediate between quantum entanglement \cite{horo} and Bell nonlocality \cite{bell}. It has been demonstrated that a quantum state which is Bell nonlocal must be steerable, and a quantum state which is steerable must be entangled \cite{jone, brun}. One distinct feature of quantum steering which differs from entanglement and Bell nonlocality is asymmetry. That is, there exists the case when Alice can steer Bob's state but Bob cannot steer Alice's state, which is referred to as one-way steerable and has been demonstrated in theory \cite{bow} and experiment \cite{han, wol}.

Quantum steering is the failure description of the local hidden variable-local hidden state models to reproduce the correlation between two subsystems, which can be witnessed by quantum steering criteria. Recently, a lot of steering criteria have been developed to distinguish steerable quantum states from unsteerable ones. In Ref. \cite{sau}, the linear steering criteria was introduced for qubit states. In Ref. \cite{sch2}, the steering criteria from entropic uncertainty relations were derived, which can be applicable for both discrete and continuous variable systems. Subsequently, the steering criteria via covariance matrices of local observables \cite{ji} and local uncertainty relations \cite{zhen} in arbitrary-dimensional quantum systems were presented. Recently, Refs. \cite{zhe1, zhe2} generalized the linear steering criteria to high-dimensional systems. Although these criteria work well for a number of quantum states, most of them require constructing appropriate measurement settings or correlation weights in practice, which increases the complexities of the detecting inevitably. The development of the universal criterion to detect steering is still one vexed question.

In this paper, we first present some steering criteria applicable for arbitrary two-qubit quantum systems, then optimize them for symmetric quantum states, and finally we provide a broad class of explicit examples including two-qubit Werner states, Bell diagonal states, and Gisin states. Compared with the existing linear
steering criterion and entropic criterion, ours can certify more
steerable states without selecting measurement settings or
correlation weights, which can also be used to verify entanglement
as all steerable quantum states are entangled.

\section{Nonlinear steering criteria for arbitrary two-qubit quantum systems}
Suppose two separate parties, Alice and Bob, share a two-qubit
quantum state on a composite Hilbert space
$\mathcal{H}=\mathcal{H}_{A}\otimes\mathcal{H}_{B}$. The steering is
defined by the failure description of all possible local hidden variable-local hidden state models in
the form \cite{wis, jone}
\begin{equation}\label{1}
P(a,b|A,B;W)=\sum_{\lambda}P(a|A;\lambda)P(b|B;\rho_{\lambda})p_{\lambda},
\end{equation}
where $P(a,b|A,B;W)$ are joint probabilities for Alice and Bob's
measurements $A$ and $B$, with the results $a$ and $b$,
respectively; $p_{\lambda}$ and $P(a|A;\lambda)$ denote some
probability distributions involving the LHV $\lambda$, and
$P(b|B;\rho_{\lambda})$ denotes the quantum probability of outcome
$b$ given measurement $B$ on state $\rho_{\lambda}$. $W$ represents
the bipartite state under consideration. In other words, a quantum
state will be steerable if it does not satisfy Eq.(1). Within the
formulation, we propose a nonlinear steering criterion that can be
used to certify a wide range of steerable quantum states for two-qubit quantum systems.

\emph{Theorem 1.} If a given two-qubit quantum state is unsteerable from Alice to Bob (or Bob to Alice), the following inequality holds:
\begin{equation}
\sum\limits_{i=1}\limits^{3}\sum\limits_{j=1}\limits^{3}\langle\sigma_{i}\otimes\sigma_{j}\rangle^{2}\leq1,
\end{equation}
where $\sigma_{i,j}$ ($i,j=1,2,3$) are Pauli operators.

\emph{Proof.} Suppose Alice and Bob share a two-qubit quantum state $\rho_{AB}$ on a composite Hilbert space, both of them perform $N$ measurements on their own states, which are denoted by $A_{k}$ and $B_{l}$, respectively. Here $B_{l}$ is a quantum observable while $A_{k}$ have no such constraint, $k (l)$ ($k (l)=1,2,\cdots,N$) labels the \emph{k}th (\emph{l}th) measurement setting for Alice (Bob). If the state is unsteerable from Alice to Bob, we have the following inequality
\begin{eqnarray}
 \nonumber
&&\sum\limits_{k=1}\limits^{N}\sum\limits_{l=1}\limits^{N}\langle A_{k}\otimes B_{l}\rangle^{2}\\ \nonumber
&=& \sum\limits_{k=1}\limits^{N}\sum\limits_{l=1}\limits^{N}\left(\sum\limits_{a_{k},b_{l}}a_{k}b_{l}P(a_{k},b_{l}|A_{k},B_{l};\rho_{AB})\right)^2\\ \nonumber
&\leq&\sum\limits_{\lambda}\left(p_{\lambda}\sum\limits_{k=1}\limits^{N}\left[\sum\limits_{a_{k}}a_{k}P(a_{k}|A_{k},\lambda)\right]^2\sum\limits_{l=1}\limits^{N}\left[\sum\limits_{b_{l}}b_{l}P(b_{l}|B_{l},\rho_{\lambda})\right]^2\right)\\ \nonumber
&=&\sum\limits_{\lambda}p_{\lambda}\left(\sum\limits_{k=1}\limits^{N}\langle A_{k}\rangle^{2}_{\lambda}\sum\limits_{l=1}\limits^{N}\langle B_{l}\rangle^{2}_{\rho_{\lambda}}\right)\\ \nonumber
&\leq&\eta \sum\limits_{\lambda}p_{\lambda}\left(\sum\limits_{k=1}\limits^{N}\langle A_{k}^{2}\rangle_{\lambda}\right)\max\limits_{\{\rho_{\lambda}\}}\left(\sum\limits_{l=1}\limits^{N}\langle B_{l}\rangle^{2}_{\rho_{\lambda}}\right)\\
&=&\eta\sum\limits_{k=1}\limits^{N}\langle A_{k}^{2}\rangle
C_{B}=\eta C_{A}C_{B},
\end{eqnarray}
where $C_{A}=\sum\limits_{k=1}\limits^{N}\langle
A_{k}^{2}\rangle,C_{B}=\max\limits_{\{\rho_{\lambda}\}}\left(\sum\limits_{l=1}\limits^{N}\langle
B_{l}\rangle^{2}_{\rho_{\lambda}}\right)$. The parameter $\eta$
($0\leq\eta\leq1$) is a constant, which is used to adjust the value
to the appropriate bound. The first inequality follows from the fact $\sum_{k=1}^{N}\sum_{l=1}^{N}(\alpha_{k}\beta_{l})^{2}\leq\sum_{k=1}^{N}\alpha_{k}^{2}\sum_{l=1}^{N}\beta_{l}^{2}$. The second inequality follows from the definition
of $C_{B}$ and the fact $\langle
A_{k}^{2}\rangle_{\lambda}\geq\langle A_{k}\rangle_{\lambda}^{2}$.
If the observables $A_{k}$ and $B_{l}$ are restricted to Pauli
matrices, i.e., $A_{k} (B_{l})=\{\sigma_{1}, \sigma_{2},
\sigma_{3}\}$, one has straightforwardly $C_{A}=3$ and $C_{B}=1$, so
Eq.(3) reduces to
\begin{equation}
\sum\limits_{i=1}\limits^{3}\sum\limits_{j=1}\limits^{3}\langle\sigma_{i}\otimes\sigma_{j}\rangle^{2}\leq\eta'.
\end{equation}
where $\eta'=3\eta$.

As we know, quantum entanglement, quantum steering, and Bell nonlocality are equivalent in the case of pure states \cite{wis, jone, ysx}. For an arbitrary quantum steering criterion, it is preferable to be a sufficient and necessary condition to detect pure states \cite{zhe1, zhe2, zhen}. In order to obtain the optimal value of the parameter $\eta'$, we introduce the pure states as reference states. For any two-qubit state, it can be expressed as
\begin{equation}\label{9}
\rho_{AB}=\frac{1}{4}(\mathbb{I}+\sum_{i=1}^{3}c_{i0}\sigma_{i}\otimes\mathbb{I}+\sum_{j=1}^{3}c_{0j}\mathbb{I}\otimes\sigma_{j}+\sum_{i=1}^{3}\sum_{j=1}^{3}c_{ij}\sigma_{i}\otimes\sigma_{j}),
\end{equation}
where $|c_{ij}|\leq1$ for $i,j=0,1,2,3$. For arbitrary pure states
$\rho_{AB}$, one has straightforwardly
$\sum_{i=1}^{3}c_{i0}^{2}+\sum_{j=1}^{3}c_{0j}^{2}+\sum_{i=1}^{3}\sum_{j=1}^{3}c_{ij}^{2}=3$
due to the fact $tr(\rho_{AB}^{2})=1$. Next we consider two cases, one is that $\rho_{AB}$ be pure separable states, then one achieves
$\sum_{i=1}^{3}\langle\sigma_{i}\otimes\mathbb{I}\rangle^{2}=\sum_{i=1}^{3}c_{i0}^{2}=1,
\sum_{i=1}^{3}\langle\mathbb{I}\otimes
\sigma_{j}\rangle^{2}=\sum_{i=1}^{3}c_{0j}^{2}=1$, and
$\sum_{i=1}^{3}\sum_{j=1}^{3}\langle\sigma_{i}\otimes\sigma_{j}\rangle^{2}=\sum_{i=1}^{3}\sum_{j=1}^{3}c_{ij}^{2}=1$,
which result in $\eta'\geq1$ due to the fact that all pure separable
states are unsteerable. The other is that $\rho_{AB}$ be pure entangled states, then one attains
$\sum_{i=1}^{3}\langle\sigma_{i}\otimes\mathbb{I}\rangle^{2}=\sum_{i=1}^{3}c_{i0}^{2}<1,
\sum_{i=1}^{3}\langle\mathbb{I}\otimes
\sigma_{j}\rangle^{2}=\sum_{i=1}^{3}c_{0j}^{2}<1$, and
$\sum_{i=1}^{3}\sum_{j=1}^{3}\langle\sigma_{i}\otimes\sigma_{j}\rangle^{2}=\sum_{i=1}^{3}\sum_{j=1}^{3}c_{ij}^{2}>1$,
which result in $\eta'\leq1$ due to the fact that all pure entangled
states are steerable \cite{zhe1, zhe2, zhen}.  So the optimal value
of the parameter $\eta'=1$. This gives the proof of Theorem 1.

In this way, we derive the steering criterion for arbitrary two-qubit
quantum systems. Whatever strategies Alice and Bob choose, a
violation of inequality (2) would imply steering.

In the following we further develop steering criterion by introducing quantum correlation matrix of local observables. Given a quantum state $\rho$ and observables $\{O_{k}\} (k = 1,2, . . . ,n)$, an $n\times n$ symmetric covariance matrix $\gamma$ is defined as \cite{ji}
\begin{equation}\label{5}
\gamma_{kk'}(\rho)=(\langle O_{k}O_{k'}\rangle+\langle O_{k'}O_{k}\rangle)/2-\langle O_{k}\rangle\langle O_{k'}\rangle.
\end{equation}

Now, let us consider a composite system $\rho_{AB}$ and a set observables $\{O_{m}\}=\{\sigma_{i}\otimes\sigma_{j}\} (i,j=1,2,3, m=3(i-1)+j)$. Similarly, the covariance matrix can be constructed as
\begin{equation}\label{6}
\gamma_{mm'}(\rho_{AB})=(\langle O_{m}O_{m'}\rangle+\langle O_{m'}O_{m}\rangle)/2-\langle O_{m}\rangle\langle O_{m'}\rangle.
\end{equation}

Obviously, the diagonal elements of the covariance matrix stand for the variance of  the observables $\{O_{m}\}$.

\emph{Corollary 1.} If a given quantum state $\rho_{AB}$ is unsteerable, the sum of the eigenvalues of the covariance matrix $\gamma_{mm'}(\rho_{AB})$ of the observables $\{O_{m}\}=\{\sigma_{i}\otimes\sigma_{j}\} (i,j=1,2,3, m=3(i-1)+j)$ must satisfied
\begin{equation}\label{7}
\sum\limits_{k=1}\limits^{9}\lambda_{k}\geq 8,
\end{equation}
where $\lambda_{k}$ is the eigenvalue of the covariance matrix $\gamma_{mm'}(\rho_{AB})$.

\emph{Proof.} For an unsteerable state $\rho_{AB}$, one has $\sum_{i=1}^{3}\sum_{j=1}^{3}\langle\sigma_{i}\otimes\sigma_{j}\rangle^{2}\leq1$ according to Theorem 1, which results in $\sum_{i=1}^{3}\sum_{j=1}^{3}\delta^{2}(\sigma_{i}\otimes\sigma_{j})\geq 8 $, where $\delta^{2}(\sigma_{i}\otimes\sigma_{j})=\langle(\sigma_{i}\otimes\sigma_{j})^{2}\rangle-\langle \sigma_{i}\otimes\sigma_{j}\rangle^{2}$  is the variance of the observable $\sigma_{i}\otimes\sigma_{j}$. To prove the corollary 1, we introduce the principal components analysis (PCA) \cite{pea, hot, jol}, which is a mathematical procedure that transforms a number of possibly correlated variables into a number of uncorrelated variables called principal components. The first principal component accounts for as much of the variability in the data as possible, and each succeeding component accounts for as much of the remaining variability as possible. Similar to classical PCA, for the quantum covariance matrix $\gamma_{mm'}(\rho_{AB})$, the variances of principal components correspond to the eigenvalues of the covariance matrix, i.e., $\sum_{k=1}^{9}\lambda_{k}=\sum_{k=1}^{9}\delta^{2}P_{k}$, where $P_{k}$ is the principal component of the covariance matrix $\gamma_{mm'}(\rho_{AB})$, and $\sum_{k=1}^{9}\delta^{2}P_{k}=\sum_{i=1}^{3}\sum_{j=1}^{3}\delta^{2}(\sigma_{i}\otimes\sigma_{j})$, one has $\sum_{k=1}^{9}\lambda_{k}=\sum_{i=1}^{3}\sum_{j=1}^{3}\delta^{2}(\sigma_{i}\otimes\sigma_{j})$. So one attains $\sum_{k=1}^{9}\lambda_{k}\geq 8 $ for an unsteerable state. A detailed proof is provided in the Appendix A.

\section{Optimized steering criteria for symmetric two-qubit quantum systems}

Symmetry is another central concept in quantum theory \cite{gro}, which can be used to simplify the study of the entanglement sometimes \cite{voll, stoc, toth}. A bipartite quantum state $\rho$ is called symmetric if it is permutationally invariant, i.e., $F\rho F=\rho$, here $F=\sum_{ij}|ij\rangle\langle ji|$ is the flip operator. In the following we optimize the steering criterion for symmetric two-qubit quantum states.

\emph{Theorem 2.} If a given symmetric two-qubit quantum state is unsteerable from Alice to Bob (or Bob to Alice), the following inequality holds:
\begin{equation}
\sum\limits_{i=1}\limits^{3}\langle\sigma_{i}\otimes\sigma_{i}\rangle^{2}\leq1,
\end{equation}
where $\sigma_{i}$ ($i=1,2,3$) are Pauli operators.

\emph{proof.}
 For arbitrary symmetric two-qubit quantum state, one has $\langle\sigma_{i}\otimes\sigma_{j}\rangle=0$, where $i, j=1,2,3, i\neq j$. So \emph{Theorem 1} reduces to \emph{Theorem 2}.

\emph{Corollary 2.} If a given symmetric two-qubit quantum state $\rho_{AB}$ is unsteerable, the sum of the eigenvalues of the covariance matrix $\gamma_{mm'}(\rho_{AB})$ of the observables $\{O_{i}\}=\{\sigma_{i}\otimes\sigma_{i}\} (i=1,2,3)$ must satisfy
\begin{equation}\label{7}
\sum\limits_{k=1}\limits^{3}\lambda_{k}\geq 2,
\end{equation}
where $\lambda_{k}$ is the eigenvalue of the covariance matrix $\gamma_{mm'}(\rho_{AB})$. A brief proof of our theorem is specified below.

\emph{proof.} For a symmetric unsteerable state $\rho_{AB}$, one has $\sum_{i=1}^{3}\delta^{2}\langle\sigma_{i}\otimes\sigma_{i}\rangle^{2}\leq1$ from Eq.(9), which results in $\sum_{i=1}^{3}\delta^{2}(\sigma_{i}\otimes\sigma_{i})\geq 2 $.  For the quantum covariance matrix $\gamma_{mm'}(\rho_{AB})$, one has $\sum_{k=1}^{3}\lambda_{k}=\sum_{i=1}^{3}\delta^{2}(\sigma_{i}\otimes\sigma_{i})$ according to PCA. So one get $\sum_{k=1}^{3}\lambda_{k}\geq 2 $ for a symmetric unsteerable state .

\section{Illustrations of generic examples}

(i) \emph{Werner state.} Consider two-qubit Werner states \cite{wern}, which can be written as
 \begin{equation}\label{8}
 \rho_{W}=p|\psi^{+}\rangle\langle\psi^{+}|+(1-p)\mathbb{I}/4,
 \end{equation}
 where $|\psi^{+}\rangle=(1/\sqrt{2})(|00\rangle+|11\rangle)$ is Bell state and $\mathbb{I}$ is the identity, $0\leq p\leq1$. The Werner states are entangled iff $p>1/3$, steerable iff $p>1/2$ \cite{wis}, and Bell nonlocal if $p>1/\sqrt{2}$. According to symmetry of the Werner state and our \emph{Theorem 2}, we achieve $p>\sqrt{3}/3$ for successful steering under the Pauli measurements $\{\sigma_{1}, \sigma_{2}, \sigma_{3}\}$. Our results are in agreement with the results of Ref. \cite{zhe1, zhe2, zhen}, which implies that the nonlinear steering criterion is qualified for witnessing steering .

(ii) \emph{Bell diagonal states.} Suppose now that Alice and Bob share a  Bell diagonal state as follows:
\begin{equation}
 \rho_{bd}=\frac{1}{4}(\mathbb{I}+\sum_{i=1}^{3}c_{i}\sigma_{i}\otimes\sigma_{i}),
\end{equation}
 where $\sigma_{i}$ $(i=1,2,3)$ are Pauli operators and $|c_{i}|\leq1$ for $i=1,2,3$. According to \emph{Theorem 2}, we find that $\rho_{bd}$ are steerable if $\sum_{i}c_{i}^{2}>1$. In this case, the local uncertainty relations steering criterion can be written as $\sum_{i}\delta^{2}(\sigma_{i}^{B})-C^{2}(\sigma_{i}^{A},\sigma_{i}^{B})/\delta^{2}(\sigma_{i}^{A})>2$ \cite{zhen}, where $\delta^{2}(A)=\langle A^{2}\rangle-\langle A\rangle^{2}$ is the variance and $C(A,B)=\langle AB\rangle-\langle A\rangle\langle B\rangle$ is the covariance. The violation is $\sum_{i}c_{i}^{2}>1$ and the corresponding states are steerable. Likely for the linear criterion we have $|\sum_{i}\omega_{i}\langle\sigma_{i}^{A}\otimes\sigma_{i}^{B}\rangle|\geq\sqrt{3}$ with $\omega_{i}\in\{\pm1\}$ \cite{sau}, and the violation implies $|c_{1}\pm c_{2}\pm c_{3}|>\sqrt{3}$. For entropic criterion we have $\sum_{i}H(\sigma_{i}^{B}|\sigma_{i}^{A})>2$ \cite{sch2}, where $H(B|A)=\sum_{a}p(a|A)H(B|A=a)$ and $H(\cdot)$ denotes von Neumann entropy. The violation is $\sum_{i}(1+c_{i})log(1+c_{i})+(1-c_{i})log(1-c_{i})>2$. It can be checked that our criterion performs equivalently well as the local uncertainty relations steering criterion, which certifies more steerable states than the linear criterion and the entropic criterion (Fig.1).
\begin{figure
\centering\includegraphics[width=0.6\columnwidth]{fig1.eps}
\caption{The performances of different quantum steering criteria for the Bell diagonal states under the conditions $c_{1}=c_{3}$. The area inside the brown solid lines denotes Bell diagonal states (BDS). The red solid line, blue circled line, green dashed line, cyan dotted line are given by the nonlinear steering criterion (NLC),  local uncertainty relations criterion (LUR), linear criterion (LC), entropic criterion (EC), respectively. States in the left side of these lines are steerable.  It is clear that the NLC performs equivalently well as the LUR criterion, which certifies more steerable states than the LC and EC.}
\label{fig1}
\end{figure}

(iii) \emph{Asymmetric entangled states.} Let us consider Gisin states \cite{gis}, which can be expressed as
\begin{equation}\label{10}
\rho_{G}=p|\psi_{\theta}\rangle\langle\psi_{\theta}|+(1-p)\rho_{s},
\end{equation}
where $\psi_{\theta}=sin\theta|01\rangle+cos\theta|10\rangle$, $\rho_{s}=\frac{1}{2}|00\rangle\langle00|+\frac{1}{2}|11\rangle\langle11|$. In Fig.2, we show the performances of the nonlinear steering criterion (\emph{Theorem 1}), the local uncertainty relations steering criterion \cite{zhen}, the linear criterion \cite{sau} and the entropic criterion \cite{sch2} for the Gisin states. It follows from straightforward calculation that the nonlinear steering criterion certifies more steerable states than the linear criterion and entropic criterion.
\begin{figure
\centering\includegraphics[width=0.6\columnwidth]{fig2.eps}
\caption{The performances of different quantum steering criteria for the  Gisin states. The cyan dotted line, green dashed line, red solid line, blue dashed line are given by the EC, LC, NLC, LUR criterion, respectively. States above these lines are steerable.  It is clear that the NLC certifies more steerable states than the LC and EC.}
\label{fig1}
\end{figure}

\section{Conclusion}

In summary, we have proposed some nonlinear steering criteria applicable for arbitrary two-qubit quantum systems and optimized ones for symmetric quantum states. These criteria can be used to detect a wide range of steerable quantum states under Pauli measurements. Compared with the existing linear steering criterion and the entropic criterion, ours can certify more
steerable states without selecting measurement settings or correlation weights, which can also be used to verify entanglement
as all steerable quantum states are entangled.

Students, teachers have new freedom to think creatively through a partnership with Discovery Education and a grant from the Horvat Family Foundation.
WESTON - Students and educators at Weston Elementary are using critical thinking, creativity, communication and collaboration as they explore intersections of science, technology, engineering, arts/design and math in their classrooms.
Weston joins schools nationwide that are working to develop lifelong learners who are technologically literate, adaptable and capable of interacting successfully with people from diverse backgrounds, to prepare them for careers that have yet to be created.
"In short, we're preparing our students — beginning in kindergarten — for the connectivity of a global society and a constantly changing workforce," Weston Elementary Principal Sarah Trimner said.
To that end, Weston Elementary has partnered with Discovery Education on a three-year program focused on STEAM instruction that spans traditional subjects.
The program began with a Discovery Education two-day summer STEAM training session for all teaching staff. In addition, eight instructors — representing each grade level plus the instructional media center and the arts — are taking part in rigorous training with a Discovery coach.
"These STEAM Innovators comprise our STEAM Team. They are the exemplars who are leading the charge — creating grade-appropriate, cross-curriculum lessons that challenge students to tackle real world problems," said Trena Loomans, Weston Elementary assistant principal.
Art class is just one area where the program's focus has added a new dimension.
"As an art teacher, I have always planned lessons that cross the curriculum," Caitlin Seeley said, "But putting the focus on STEAM has reminded me to slow down and point out when and how those connections are being made."
Earlier this year, Seeley's third-, fourth- and fifth-graders turned 2-D self-portrait drawings into 3-D paper bobbleheads.
"We had a great discussion about how artists, engineers and scientists think alike, and students explored many different solutions while completing the project," Seeley said.
The district also is working to build a parent and community component into the program, examining opportunities to partner with post-secondary educational institutions and local businesses to provide STEAM vocational and employability skills courses for adults and help employers address workforce gaps.
With the support of a $3,000 grant from the Horvat Family Foundation, the school now hosts biweekly Maker Space time in each classroom. Students work in small groups to solve a problem.
The structure give students space to take a lead in their learning.
"Ultimately, we're pushing the envelope to give teachers and students the freedom to think about what success in learning looks like," Trimner said. "There's not just one type of learning and one type of success for one type of student.

Groundwork Erewash Valley works to improve all environments, from woodlands to schools and housing estates. Groundwork aims to involve the community in improving and maintaining their environment, and educating communities in the importance of biodiversity, recycling and waste management.
Groundwork manages officially designated Local Nature Reserves within the Derby & Derbyshire area. These can be in rural areas, but are more often what we term as 'green oases' and can be found throughout urban areas.
The Community Wildspaces project encourages local communities to become actively involved in maintaining their existing environment and in creating new 'green oases' in their local areas.
The scheme also aims to develop better access and interpretation on these sites, as well as holding events to raise awareness of nature reserves and green spaces, that are on people's doorsteps.
The arts have always been used by Groundwork as a regeneration tool and can help make a significant contribution to communities and the environment. Art is a successful way of engaging people from all ages, backgrounds and cultures and encouraging participation and celebration.
Groundwork has established good links with community arts organisations to manage, commission and deliver a wide variety of arts projects and programmes. More recently Groundwork in the East Midlands has developed a strategic arts policy through a new Arts programme.
The programme involves 14 artists from a range of backgrounds providing advice, guidance and support to staff. The artists will be working within the Trusts to help devise inventive and relevant artists briefs by looking to at upcoming projects and considering how they can become involved and the ways artists can be used in the future.

Q: WPF - Animation to make an error message disappear I have the following xaml in my window:
<Border Height="100" BorderBrush="Black" BorderThickness="2" CornerRadius="10" Background="PaleVioletRed" HorizontalAlignment="Center" VerticalAlignment="Center">
   <TextBlock Margin="10"  HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="17" FontWeight="Bold">Error Message Here</TextBlock>
</Border>

Which basically displays this:
alt text http://xs.to/thumb-4CB2_4B69F8E6.jpg
I plan to bind it's Visibility to an error state variable so it shows when an error occurs.
But I don't want to show it for a long time.  I would like it to disappear/fade after 2 seconds.  Is there a way to do this via XAML?  Or a nice WPF way?
Something like this psudo code logic:
when (ErrorMessage.Visibility == Visible )
{
    Wait(2000); // Wait 2 seconds
    ErrorMessage.Visibility == Collapsed;
}

but preferable done with XAML.
My instincts tell me there is a way to do this with an animation, but I am not an animation expert and could use some help.
The other option is to try and setup a timer and control it with that.

A: use something like this....
<EventTrigger RoutedEvent="Page.Loaded">

    <BeginStoryboard>
         <Storyboard BeginTime="0:0:1">
              <ObjectAnimationUsingKeyFrames Storyboard.TargetName="image1" Storyboard.TargetProperty="Visibility">
                    <DiscreteObjectKeyFrame Value="{x:Static Visibility.Visible}" />
                   </ObjectAnimationUsingKeyFrames>
              </Storyboard>

    </BeginStoryboard>
    </EventTrigger>

change the routed event to match your needs, set the BeginTime on the storyboard to 2 mins ( or whatever ), set the targetname to your border element.

Q: Foreign key values without navigation properties Is it possible to assign foreign key values manually when inserting records?
I do not want to use a TransactionScope or similar construct. But i do want to set the foreignkey value before calling SaveChanges()
For example:
EntityX x = new EntityX();
x.Name = "test";
ctx.AddToEntityX(x);

EntityY y = new EntityY();
y.Name = "Test";
y.EntityXID = x.ID; // <--- I want this. Not using a navigation property, but its 0.
ctx.AddToEntityY(y);

ctx.SaveChanges();

A: yes it is possible but a lot of trouble you have to assign it trough EntityReference :
y.EntityXReference.EntityKey = new EntityKey("Enitites.YSet", "Id", x.id);

see EntityKey Constructor
 for details of parameters
for other reference see Tip 7 - How to fake Foreign Key Properties in .NET 3.5 SP1

A: I don't see any problem with using navigation property in your example. Also there is no need for transaction scope because SaveChanges uses transaction internally.
Theoretically if you delete all associations in your conceptual model (EDMX designer) and manually delete all associations in SSDL part of EDMX file and then map FKs to new scalar properties you should be able to do that. But you will degrade EF so much that you should even not use it and revert back to ADO.NET or Linq-to-sql. Moreover once you touch SSDL part of EDMX you can't use Update from database anymore.

A: If you create a new entity it won't have an ID until it get's persisted. Then you would have to retrieve it from the DB and get the idea. Using navigation properties is definitely your best choice in this example. So instead of:
y.EntityXID = x.ID;

you would use
y.EntityX = x;

Policy on scripts and bots
george moromisato
Contact george moromisato
FYI: I just updated the Terms of Service to include a section on writing scripts and bots. The section reads:
You may write non-commercial scripts and/or bots to access any of our services, provided you adhere to community rules: don't try to gain unauthorized access, don't degrade the service for others, and don't do anything illegal.
You may create non-commercial, alternate UIs and access methods for any of our services, provided you adhere to the community rules. For example, you may create an alternate Anacreon client that connects to the official Anacreon server.
You may not distribute commercial products that connect to any of our services without prior permission.
In all cases, we reserve the right to alter service APIs as we deem appropriate.
My intent is to have a very permissive policy that encourages people to write scripts (or even alternate clients). At the same time, if bots change the playing experience for human players, then we reserve the right to change the game and/or APIs. In particular, I don't want human players to feel that they are at a disadvantage when playing against bots.
Let me know what you all think and I can clarify/change as needed.

Sounds very reasonable George.
Will be interesting to see what people come up with.

Scuppered or scuttled?
Paul Berg writes: "In today's Globe, writing about the Bhutto assassination investigation, Associated Press writer Chris Brummitt offers the following: 'Lack of political will and fear of upsetting powerful vested interests will probably scupper any efforts to find Benazir Bhutto's assassins.'"
Didn't the writer mean "scuttle"? he asks, citing Merriam-Webster's Online Dictionary. There scupper is defined as "an opening cut through the bulwarks of a ship so that water falling on deck may flow overboard" while scuttle means "sink or attempt to sink [a ship] by making holes through the bottom" and also "destroy, wreck or scrap."
Under scupper the verb, however, M-W does give the sense "do in" -- a sense that's way more common in British English than American. (And yes, Chris Brummitt -- judging by his appearance on "The PBS NewsHour" -- speaks British English.) A Nexis news search returns just three uses of scupper in the past month in US newspapers and wires, versus roughly 400 in UK publications.
Scupper has somewhat murky origins, it's true. The OED's first sense for the verb is "To surprise and massacre," a usage labeled military slang and dating to 1885. The meaning "defeat, ruin" shows up by 1918, but the first guess at etymology comes only later, with the 1993 additions to the dictionary: "The connection [to the noun scupper] is perh[aps] explained by Fraser & Gibbons Soldier & Sailor Words (1925)," which noted that "A man killed in action or falling in heavy weather would naturally roll into the scuppers."
The 1993 additions also include a new definition of scupper, dated to the 1970s: "To sink (a vessel) deliberately; = SCUTTLE ... (with which it is sometimes confused)."
So in the OED's view, "scupper a ship" is a (fairly recent) mistake for "scuttle a ship." But "their plans were scuppered" is standard usage, nearly a century old.
I'm going to nominate scupper vs. scuttle for Lynneguist's "Difference of the day." Thanks for the tip, Paul!
Ah, so that's where the Antelope's drunken cook was....
You know, I wouldn't have thought I was at all confused about this pair of words, but I now realize that I have been, just a bit, and that "scudder" is part of the problem.
Looking up "scud", I find, irrelevantly, that in addition to the meanings that have anything to do with being blown along by the wind, it can mean (Century Dictionary, sense 15) Dirt, lime, and fat left in the grain of a skin after it comes from the puer.
Hence, presumably, the Scottish expression "in the (bare) scud" meaning naked.

As a former Harland & Wolff Shipyard, Belfast, ship's plumbing apprentice, I often went out to berthed vessels and building yards to fit new 'scuppers'. They were usually 2-3" galvanised pipes fitted by flange to the underside of exposed decks to drain off rain or sea splash. Nothing whatever to do with scuttling a ship, which is to sink a ship by opening the 'sea cocks' in the bottom of a ship. Sometimes, even in a floating ship this is necessary: when the hull has been breached on one side and some compartments are flooded, which often happens with battle damage or running aground. Scuttle or sea cocks are then opened in evacuated bottom compartments on the opposite side to stabilise the vessel. Sometimes, the Captain or First Mate, will order the pumping of the ship's oil into an empty opposite compartment, if it is safe, to avoid the corrosive effects of sea water. Of course, that other notorious ship of Harland & Wolff, Titanic, would not have been saved by this as her portside hull was breached by contacting the undersea edge of the iceberg and grounding on its undersea shelf, on her fateful maiden voyage. "The collision had forced the metal to buckle inwards and popped rivets below the waterline, opening the first five compartments (the forward peak tank, the three forward holds and Boiler Room 6) to the sea". There is further evidence to suggest that two bottom plates fell off as a result of her grounding, and probably many more crushed inwards, which further weakened her 'back', causing Titanic to split in two before she slipped beneath the surface.
Just say "Beembo"

DURHAM, NC – Khalil Herbert ran for 208 yards and two touchdowns to help shorthanded Virginia Tech hold off Duke for a 38-31 win. The Kansas graduate transfer's big day included a 60-yard score with 2:20 left to help keep the Hokies in control. Braxton Burmeister also ran for two scoring keepers for the Hokies. Virginia Tech didn't have 21 players and two full-time coaches due to a combination of coronavirus and injury issues. Deon Jackson ran for two touchdowns to lead the Blue Devils. Duke's 0-4 start is the program's worst since going 0-12 in 2006.
This is the second consecutive week that the Hokies have rushed for 300+ yards.

Christopher Plummer To Receive Career Achievement Award
Written by: FFT Webmaster | January 9th, 2012
Veteran actor Christopher Plummer, the current frontrunner in the Best Supporting Actor Oscar race for his heartfelt performance as a man who comes into full flower in his final years in the film BEGINNERS, will receive the Modern Master Award, the highest honor bestowed by the Santa Barbara International Film Festival later this month. Although well loved by the public for his role as Captain Von Trapp in the Hollywood blockbuster version of THE SOUND OF MUSIC (1965), the Canadian-born actor has been in many distinguished films over a career that now spans six decades. Beginning with his debut in STAGE STRUCK (1958), he has had memorable roles in such films as THE MAN WHO WOULD BE KING, WATERLOO, TWELVE MONKEYS, THE INSIDER, A BEAUTIFUL MIIND, SYRIANA, INSIDE MAN and THE LAST STATION, to just mention a few. He is currently on screens around the world in a supporting role in director David Fincher's adaptation of THE GIRL WITH THE DRAGON TATTOO, and will next portray stage and screen legend John Barrymore in BARRYMORE, a film adaptation of the one-man show for which he won the Tony Award on Broadway. Plummer joins an illustrious group of past recipients including Michael Douglas, Jodie Foster, Sir Anthony Hopkins, Diane Keaton, Sean Penn, Jeff Bridges, Peter Jackson, George Clooney, Will Smith, Cate Blanchett, Clint Eastwood, James Cameron, and Christopher Nolan.

Solution home Reflector 2 Reflector 2 FAQ
Why do I have to pay for Reflector 2?
Modified on: Wed, Oct 5, 2016 at 1:55 PM
Reflector 2 is an entirely new product. It has a ton of new features including Google Cast mirroring support, an all new control menu, YouTube live streaming, iOS 9 and 10 support, enhanced device layouts, voice-over recording and two iOS companion apps—Reflector Director and Reflector Student.
Reflector Director allows remote control of Reflector 2 (https://itunes.apple.com/us/app/reflector-director/id974747588?mt=8) and Reflector Student aids in discovery on complex networks while allowing one iOS device to view others that are being mirrored to Reflector 2 (https://itunes.apple.com/us/app/reflector-student/id1002083080?mt=8).
iOS 9 and 10 represents an entirely new AirPlay. Apple has taken serious time to improve the AirPlay protocol and has changed and improved nearly every aspect. While investigating the changes and working to add support to Reflector 2, we quickly realized that adding iOS 9 and 10 support to Reflector 1 would be incredibly difficult because of the way Reflector 1 was architected. As we dug deeper, we found many areas that would require significant rewrites of Reflector 1, more or less re-creating Reflector 2. Because of this extensive work required, we've determined it's not feasible for us to add iOS 9 and 10 support to Reflector 1.
Reflector 2 is much more than just a basic, free update. You can read all about the new features of Reflector 2 here: http://www.airsquirrels.com/reflector/features/
We have provided numerous, free functionality updates to Reflector for nearly three years. Because of the new technologies, features and functionalities, the price for Reflector 2 is $14.99 for a single license. You still only need one license per computer!
The original release of Reflector will continue to function as normal with devices running iOS 8 and lower versions.
