« Further Evidence That Too Many People Are Famous | Main | Cognitive Dissonance »
Heading For Jonestown
I've marveled, the last couple of days, how the crackpot right can muster outrage over such a small thing as the President's choice of mustard. I have, in the past, assumed that similar outbursts were symptoms of insanity. Doug over at Balloon Juice goes meta and clarifies things for me:
if you look at it from the right perspective. Dijongate—along with a great deal of what happens on Glenn Beck—doesn't make any sense. It isn't clear to me that it's even supposed to make sense...I can't help but feel that the whole texture of wingnuttia is starting to feel different these days. And that more generally, any kind of mythology eventually moves towards forms that cannot be understood on a literal level.
If you look at the overblown reaction of the far right to utterly insignificant "outrages" it becomes clear: these are neither sincere reactions nor empty political posturing. They're much more complicated than that. They're rituals designed to simultaneously bond and reassure a diminishing community of True Believers.
I've assumed that the right would catch on to how nutty it sounds when it accuses President Obama of being, for example, simultaneously fascist and socialist. I've assumed they'd moderate their rhetoric so they didn't sound loony. Now I understand: rationality is not an issue because the point of what they're doing is not to persuade people on the outside to come in, but to reassure those on the inside that they're members in good standing of a viable "movement." In a threatening environment, the best way to do that is to move toward forms that, as Doug says, can not be understood on a literal level.
So, like members of a cult which perceives itself under attack, the far right is talking more and more only to itself, using code words and constructs that are indecipherable to those on the outside. They are, in effect, preparing for the ultimate act of purification, after which they'll be out of our hair for a while.
Gotta admit... the mustard thing is ridiculous.
See Steve: you're not a cult member.
Know hope!
Yeah, I mean if he had asked for Hunts ketchup instead of Heinz that would be an issue!!! :)
Where do I send the KoolAid?
Posted by: Richard | 05/07/2009 at 04:45 PM
Well, yeah, Steve. But that's something that matters.
Tom, read the original posts. The guy was making a point about MSNBC engaging as Obama PR department by just happening to be at a hamburger joint, with a top reporter like Andrea Mitchell in tow, actually reporting live about Obama and Biden trying to play the "common folks card."
The dijon part was a bit of a gentle sense of conservative self-mocking (gasp, he ordered French mustard!) which when picked up the lefty blogs, conveneintly left out the self-satire tone.
So in recap: a guy pokes fun at himself, and liberal blogs intentionally portray his tongue in cheek as seriosness.
Pretty lame.
I think you detect self-deprecating humor in paces where it doesn't exist.
Lee is right. The whole Dijon thing on the blog was clearly a joke, you're just too far gone to get it. You know, kind of like all those "wingnuts" you like to mock. Different side of the same coin brother.
But that's not important. What is important is that there is a serious point to be made here. Dijon mustard on a hamburger? That is just poor taste! Dijon is a fine mustard and on sausages, or sandwiches it can be a marvelous addition. But a hamburger demands good old yellow mustard! And i'm not talking inferior products like the dreck put out by French's. At the very least a Ploughman's is required. The fact that O'Bama doesn't understand this is just further evidence of the man's poor taste. Any foodie worth their weight will agree. It isn't a question of liberal or conservative, but one of right and wrong.
And just so my mustard props are credentialed, yes, that was me berating a waitress in Miller's Pub in Chicago several years ago for not having a single jar of yellow mustard in the entire restaurant. And for the record, my tirade finished with the statement, "that;s just not American, dammit!"
Next time you're in Miller's, ask for yellow mustard. I guarantee you get it.

Tiffany procures retail solutions for Trump Tower-related security measures | @tiffanyandco @cotyincpr
FROM LUXURY DAILY | DECEMBER 2016, 19
[LIRE L'ARTICLE EN ENTIER]
Tiffany & Co.'s Fifth Avenue flagship's proximity to Trump Towers has resulted in an unlikely branding effort for the U.S. jeweler.
The jeweler's iconic flagship, known for its cameos in Hollywood films and its annual holiday windows, finds itself on the same block as Trump Towers, the Midtown Manhattan home of U.S. President-elect Donald Trump. Since the election results were announced Nov. 8, protesters have been picketing outside the building, causing the Secret Service and New York Police Department to heighten security along Fifth Avenue, just in time for the holiday season.
"The truth is that politics and business do not mix, and when those worlds collide, good things rarely happen," said Rob Frankel, branding strategist & expert at Frankel & Anderson, Los Angeles. "'Cause marketing' is a huge myth, often alienating as many (or more) prospects than it might attract. "Overall, I see this less as a political statement and more along the lines of the signs you see posted when a store is remodeling, which proclaim 'Pardon our dust! We're open for business!'" he said. "Nobody really notices and business doesn't improve until the signs are removed and foot traffic returns to normal."
Branded barricades
As a result of the extra security measures, storefronts near Trump Tower's, including Tiffany and Gucci, which has its New York flagship within the tower, have seen decreased foot traffic as barricades deter shoppers and worsen congestion on the already busy thoroughfare in Midtown Manhattan.
Barricades along the street caused Tiffany to cancel its holiday window reveal. While the store remains in business with normal hours, its sales are expected to take a hit this year, according to CNBC.
In addition to the imposing presence of the metal blockades, security personnel have also been on heightened alert. Individuals headed to the luxury stores around the tower are the only ones getting through to the sidewalk, but this means potential shoppers enduring questioning by police before they are allowed to pass (Trump's midtown Manhattan base causes problems for luxury retail).
Tiffany, for one, has partnered with the New York City Police Department to make the most of the security presence by designing branded covers for the police barricades.
The barricades, dressed in Tiffany blue slipcovers, have been positioned from 57th Street around to the jeweler's entrance on Fifth Avenue, thus creating a Tiffany "safe zone."
Doing so provides a pathway for passersby to view Tiffany's annual holiday windows. While this solution ensures some consumers get to experience its windows, Tiffany likely missed out on the attention and crowds that make it a point to see its display this year.
The placement of the branded barricades also allows consumers to enter the flagship through its main entrance. Prior to the barricades being set up, consumers were encouraged to use the jeweler's side entrance facing 57th Street.
In a statement the jeweler said: "Tiffany is in frequent communication with the New York Police Department and U.S. Secret Service regarding safety and security along the perimeter of our Fifth Avenue flagship. We remain open for business with regular hours and welcome customers to enter the store via our 57th Street entrance while any barricades along Fifth Avenue are in place.
"Our iconic flagship store windows, which feature sparkling scenes of New York City at the holidays, are now on display for all to see. Our façade has also been illuminated as planned."
Alternate viewings
A digital solution has also been implemented to ensure that consumers who would rather not visit in person due to the barricades and upped police presence can still experience the windows.
Tiffany, Louis Vuitton and Cartier are among the 18 New York storefronts getting a digital audience this holiday season with help from Google. Google's "Window Wonderland" recreates the feeling of strolling outside iconic retailers on a consumers' desktop computer, mobile phone or tablet.
While about 5 million tourists descend on New York this time of year, many located in other cities, states or countries will not be able to get to see these in person, making this Google experience the next best thing.

#Luxury #Stores Will Be Based on #Experience and #Design Flexibility
In order for retailers to better understand the process of experience-first luxury design, co-founders Jeremy Bergstein and Dave Skaff outlined five steps for architects, designers and retail companies to create thought-out spaces from the onset of the build process:
1- Consider the 'New Retail Architecture' – Physical architecture and digital architecture have to get to know each other. Enterprise technology influences almost every element of the modern customer experience. These systems are too critical to the core service the store delivers to ignore early on. You need to build on a strong foundation before you can architect any type of shoppable brand space.
2- Think Beyond the Space – Customers are interacting with your brand inside and outside of store lease lines. Understand early on how your customers are engaging with the brand so you can enchant them and build experiences to meet them where they are.
3- Leverage Historical Data – Don't underestimate the power of data, and be prepared to make changes along the way. Data can inform everything from hyper-optimized regional store marketing and assortments to store displays, experiences and layout.
4- Give Customers What They Want – Now that you know your customer, "architect" your space so guests will stay longer and give them an opportunity to have a personal moment with brand and product.
5- Allow For Flexibility – Remember that key elements like flexible checkout and fulfillment are now table-stakes for a complete customer experience. Flexibility impacts physicality in an store environment.
The Science Project (TSP) is a luxury retail design firm based in New York City. From Kate Spade to Perry Ellis and Barneys New York, they have continually pushed the boundaries of what truly defines "experience" in meaningful, well-thought-out ways that work across the digital, data and built environments and push the traditional boundaries of architecture.

Next wave of store closings may hit luxury [NYC] [#CNBC #NYC #fifthavenue]
CNBC, 17/02/2016.
It isn't every day you see a sign boasting 40 percent off in the window of a luxury shop. But as real estate executive Andy Graiser walked past one of Prada's New York City boutiques a week before Christmas, that's exactly what he encountered.
Though the design house is working through some internal issues (namely, products that have fallen flat with their target demographic), Graiser, founder of A&G Realty, said such deep discounting at a luxury shop is indicative of broader woes across the luxury space — troubles that could result in the segment being next in line to trim its store fleet.
The problems that luxury firms are battling are twofold. For one, they're facing macroeconomic pressures including a sinking stock market, stalled global growth and a stronger dollar, all of which discourage the high-end consumer from spending. For another, they're trying to sell their wares to a group of shoppers who have become less focused on material goods, and are instead more interested in dining out or travel — a trend that could have long-term implications for the industry.
Due to these factors and an overall glut of retail space in the U.S., Graiser predicts luxury retailers will be next in line to close some stores, as they try to compete in a country that has more than two times the retail space per capita than the United Kingdom, France, Brazil and Germany combined.
"There are real issues with some of these luxury players," Graiser said. "There's going to be a lot more closures that are going to be occurring."

Centurion successfully advocates for Equatorial Guinea OPEC membership
PRESS OFFICE: Centurion Law Group
Centurion congratulates the Ministry of Mines and Hydrocarbons for bringing Equatorial Guinea into OPEC, an initiative that demonstrates the massive progress made by the nation since the first oil and gas developments of the 1990s.
At yesterday's 172nd meeting of the OPEC members, Equatorial Guinea's Minister of Mines and Hydrocarbons H.E. Gabriel Mbaga Obiang Lima met in a closed session with the OPEC ministers, who voted to accept the country's application to join the bloc. The Ministry of Mines and Hydrocarbons, which employed Centurion's advocacy and lobbying services, applied to join OPEC in January 2017 and had its application accepted just four months later.
H.E. Gabriel Mbaga Obiang Lima praised Centurion on its work facilitating the negotiations for Equatorial Guinea to join OPEC: "Our nation, and Africa as a whole, needs more companies that are as committed to our collective progress as Centurion. The Government of Equatorial Guinea commends Centurion and its attorneys for their success in helping our nation join OPEC. Equatorial Guinea now stands tall among energy producers worldwide."
NJ Ayuk, CEO of Centurion, stated: "The OPEC deal is huge for Equatorial Guinea, a country which advocates for African interests and African prosperity, whether in business or diplomacy. Centurion's purpose is aligned with that of the country and its government, and we are proud of the role that we have played in bringing Equatorial Guinea into OPEC."
Equatorial Guinea is, as Centurion has always advocated, a place for innovative energy pioneers. The firm has played an active role in bringing investment to Malabo and facilitating the growth of the energy sector. Key developments have included deepwater oil and gas production, LNG exports, methanol production, CNG public transport, and renewable power. In 2017 the Ministry of Mines and Hydrocarbons is working on keystone projects that include a petrochemicals complex (REPEGE), tank farm (Bioko Oil Terminal) and the finalization of the 2016 bidding round (EG Ronda 2016). Equatorial Guinea's entry into OPEC provides a new framework for cooperation on these and future energy innovations.
H.E. Gabriel M. Obiang Lima and NJ Ayuk will speak at the Africa Oil & Power conference on June 5-7 in Cape Town, where Mr. Ayuk will also launch his new book, Big Barrels: African Oil & Gas and the Quest for Prosperity.

\section{\label{sec:intro} Introduction}

Experimental studies of interacting quantum systems are increasingly focusing on non-equilibrium setups, e.g., driving cold atom systems or electronic materials dynamically through various finite temperature and quantum phase transitions \cite{paillard01,kaiser14,loth10,bloch05,sadler06,ritter07,trotzky11,schreiber15}. Theoretical modeling of systems under these conditions is even more challenging than the already difficult problem of computing equilibrium properties of quantum systems away from perturbative regimes. Exact numerical calculations are possible for small systems, and there has been some success in studying issues such as thermalization and many-body localization~\cite{nandkishore15,vosk13,pal10,oganesyan07,imbrie16,gornyi05,baskoa06}. Reaching system sizes sufficiently large enough for modeling experiments is still difficult in most cases, with the exception of some one-dimensional (1D) systems where the density-matrix renormalization group (DMRG) method (or the closely related matrix-product states) now allows for time-evolution studies on relatively large system sizes and long times \cite{daley04,schollwock05,schollwock11}. For higher-dimensional systems the challenges in real-time calculations are formidable.

Given the difficulties with real-time evolution, alternative ways to extract non-equilibrium dynamical properties of quantum systems have been explored in the imaginary-time domain, where quantum Monte Carlo (QMC) methods can be applied. In equilibrium, there are solid relationships between real- and imaginary-time correlation functions which can be exploited in numerical analytic continuation of QMC data~\cite{jarrell96}. Much less is known about practical ways to infer real-time properties from imaginary-time calculations out of equilibrium, though some progress has been made on this front recently. Examples include studies of systems driven through a quantum critical point \cite{degrandi11,degrandi13,liu13} at different velocities or according to non-linear protocols, where Kibble-Zurek scaling \cite{kibble76,zurek85,polkovnikov05,zurek05,dziarmaga05,zhong05,chandran12,liu14} can be used to extract the dynamic exponent and other important quantities such as the quantum geometric tensor \cite{micheal14,degrandi11,degrandi13}. An important observation here is that real- and imaginary-time evolution are identical not only in the adiabatic limit, where both dynamics keep systems in their instantaneous ground states, but also including the leading non-adiabatic effects. Another example is the phenomenon of ``initial slip'' \cite{yin14,zhang14,shu17,chiocchetta16,liu16}, where a random product state is evolved by a Hamiltonian tuned to a quantum-critical point and the state initially becomes increasingly ordered, before developing critical fluctuations and vanishing long-range order. The transient states produced before one reaches the critical equilibrium state have interesting properties that can be probed in imaginary-time \cite{yin14,zhang14,shu17}. Imaginary-time evolution has also been used to investigate the emergence of topological conservation laws \cite{shao15}.

In this paper we use the imaginary-time approach to study the relaxation mechanism of the order parameter in quantum antiferromagnets with O($3$) rotationally-invariant order parameters. The system, described by a Hamiltonian $H$, is initially prepared in a fully saturated antiferromagnetic state with the order parameter along the $z$ spin axis. Evolving this state in imaginary-time $\tau$ with the operator ${\rm e}^{-\tau H}$, the rotational symmetry will eventually be restored marked by the expectation value of the $z$ component of the order parameter decaying to zero. We identify short- and long-time behavior of the dynamics and develop theoretical and practical tools for analyzing emergent scaling behaviors by defining an effective dynamic exponent for a given threshold value of the $z$ component of the order parameter. As we shall show in this paper, this effective dynamic exponent converges to the true dynamic exponent as the threshold of the order parameter is lowered to $0$. In addition to delivering the dynamic exponent, which is not very surprising (though useful in its utility as a tool to extract the exponent), we show that the asymptotic long-time, large-system scaling behavior contains valuable information on the nature of the high-energy states. In a clean 2D Heisenberg antiferromagnet we observe fast convergence of the effective dynamic as the threshold order parameter is decreased, which we argue is indicative of the expected ``Anderson tower'' of quantum rotor states \cite{anderson52}. In other words, the scaling is characterized by an constant effective dynamic exponent $z=D$ ($D$ being the dimensionality of the system) for a large range of values of the order parameter. In contrast, in a 2D system randomly diluted at its percolation point, we find that the effective dynamic exponent increases as the threshold order parameter goes to 0, converging toward a fixed value only when the order parameter is small. This demonstrates a hierarchy of excitations which forms tower governed by a common dynamic (size-scaling) exponent only at low energies. The ultimate low-energy value of the dynamic exponent is $z = 3.90(1)$, which improves in previous estimates $z \approx 3.7$ obtained using different methods \cite{wang06,wang10,ghosh15}. These results reinforce the notion that lowest excitations of the system at the percolation point are not conventional Anderson quantum rotor states (Goldstone modes \cite{anderson52,goldstone62}) although the system breaks the $O(3)$ spin symmetry spontaneously in the thermodynamic limit \cite{sandvik02,vojta95}.

The outline of the rest of the paper is as follows:
In Sec.~\ref{sec:theory} we will describe the theoretical underpinnings of our approach. In Secs.~\ref{sec:cleanheisenberg} and \ref{sec:percolating} we
discuss results for the pure 2D Heisenberg model and the diluted system, respectively. We summarize our study and provide some further remarks
in Sec.~\ref{summary}.

\section{\label{sec:theory}Relaxation and Finite Size Scaling}

As mentioned in the introduction our setup will be the following: We prepare our system initially in a fully saturated antiferromagnetic state denoted by $|\psi_0\rangle$, and evolve in imaginary time with $\mathrm{e}^{-\tau H}$ where $H$ is a Heisenberg Hamiltonian describing a gapless quantum antiferromagnet.  Because the ground state obeys the symmetry of $H$ we know that this initial state will not be an eigenstate of $H$ but it will have some overlap with the ground state, as they share the same ordering. As the state evolves in imaginary-time it will eventually decay to the ground state, restoring the rotational symmetry of our system. From the theory of spontaneous symmetry breaking we know that in the limit of system size tending to infinity, a set of excited states just above the rotationally symmetric ground state become degenerate allowing the system to spontaneously align along a particular axis when subjected to an infinitesimal perturbation \cite{d_fisher89,goldstone62}. In imaginary-time this phenomena will manifest itself as a divergence in the relaxation time to reach the ground state as the system size is increased. We will use the staggered magnetization $m_s^z$ along the $z$ spin axis
\begin{equation}
m_s^z = \sum_{i_x,i_y} (-1)^{i_x+i_y} S^z_{i_x,i_y},
\end{equation}
as a measure of the restoration of rotational symmetry as our state is evolving in imaginary-time. The expectation value of this operator as a function of imaginary-time is given by:
\begin{equation}
\langle m_s^z(\tau) \rangle=\frac{\langle\psi(\tau)|m_s^z|\psi(\tau)\rangle}{\langle\psi(\tau)|\psi(\tau)\rangle},\label{eq:exp}
\end{equation}
where $|\psi(\tau)\rangle$ is the imaginary-time evolved state:
\begin{equation}
|\psi(\tau)\rangle=\exp\left(-\tau H\right)|\psi(0)\rangle.
\end{equation}
Expanding in eigenstates of $H$, denoting the eignestates and eigenenergies by $|n\rangle$ and $\epsilon_n$, respectively, and defining the gap,
$\Delta=\epsilon_1-\epsilon_0$; in the limit $\tau\rightarrow\infty$, the expectation value in Eq.~(\ref{eq:exp}) will vanish as
\begin{equation}
\langle m_s^z(\tau)\rangle \approx\left(\langle 0|m_s^z|1\rangle \frac{c_{1}}{c_{0}} +~\mathrm{c.}~\mathrm{c.}\right)e^{-\Delta\tau} + \cdots,\label{eq:asm_imag_time}
\end{equation}
where $c_n=\langle n|\psi_0\rangle$. Since the ground state is symmetric under rotations we have that $\langle 0|m_s^z|0\rangle=0$. let us define the relaxation time $\tau_r$ as the time where $m_s^z(\tau)$ drops below some threshold $m_\mathrm{threshold}$. Equation~\eqref{eq:asm_imag_time} suggests that as this threshold goes to 0, $\tau_r \sim 1/\Delta$. Therefore in this limit, by calculating the scaling $\tau_r$ with system size, we can infer the scaling of the low energy gap of $H$.

One can characterize this scaling of the low energy gap by the dynamic exponent $\Delta\sim L^{-z}$ which has different interpretations depending on its value. $z=0$ implies that the system has a finite gap in the thermodynamic limit, while finite $z$ means the system has gapless excitations, and finally $z=\infty$ denotes exponential scaling of the gap. If we consider systems which have gapless excitations, a finite dynamic exponent implies the relaxation time should scale as a power law: $\tau_r\sim L^z$. In other words, if one rescales the time axis by $L^z$, $\langle m_s^z(\tau)\rangle$ should show scaling collapse at small $m_\mathrm{threshold}$. For some Hamiltonians there exists a large, but sub-extensive, number of low energy states which have energies (relative to the ground state) that have the same scaling as the low energy gap~\cite{anderson52,goldstone62}. The existence of these states will have the effect that there will be a larger window of $m_\mathrm{threshold}$ for which this scaling collapse holds. This is because higher order terms in Eq.~(\eqref{eq:asm_imag_time}) will have energy exponentials which all scale in a similar manner with system size. This argument will be important later when we discuss the differences between the clean and diluted 2D Heisenberg models in later sections.

The preceding arguments, however, become valid asymptotically in the limit $L\rightarrow\infty$ and so it is necessary to take into account finite size corrections if one would like quantitative estimates for the dynamic exponent. As we will explain in the rest of this section, it is possible to control for the effects of finite size deviations by calculating the "flow" of the dynamic exponent from finite-size systems in a similar manner as the techniques used in finite-size scaling near critical points in equilibrium~\cite{nightingale82,brezin82,derrida83,luck85}. Using these methods one can extrapolating the finite-size results to the thermodynamic limit.

To estimate the dynamic exponent from finite size systems we start by calculating the relaxation times $\tau_r$ and $\tau_r'$ (at some finite value of $m_\mathrm{threshold}$) for two different system sizes $L$ and $L'$ respectively. From this, the dynamic exponent can be estimated by rescaling the two times by their respective system sizes such that the rescaled results are equal:
\begin{equation}
\tau_r L^{z(L,L')}=\tau_r'L'^{z(L,L')}.\label{eq:dyn_z}
\end{equation}
From this expression we can define a finite size exponent for the pair of system sizes $z(L,L')$:
\begin{equation}
z(L,L')=\frac{\log(\tau_r/\tau_r')}{\log(L/L')}.\label{eq:z_L}
\end{equation}
As $L,L'\rightarrow\infty$, this finite size exponent will converge to what we shall call the effective dynamic exponent (recall that $m_\mathrm{threshold}$ is finite) which we will denote as $z_\infty$. The manner in which $z(L,L')$ converges to infinite size is determined by corrections to the $L^{-z_\infty}$ scaling of $\Delta(L)$. To see this, one can parametrize the corrections to the low energy gap with correction exponents $\omega_i$:
\begin{equation}
\Delta(L)=L^{-z_\infty}(1+c_1L^{-\omega_1}+\cdots).
\end{equation}
Now modifying Eq.~(\ref{eq:dyn_z}) to include corrections we get:
\begin{equation}
\tau_r \Delta(L)=\tau_r'\Delta(L').
\end{equation}
Using this equation and Eq.~(\eqref{eq:z_L}) we find that $z(L,L')$ converges to $z_\infty$ as:
\begin{equation}
z(L,L')=z_\infty+c_1\frac{L^{-\omega_1}-L'^{-\omega_1}}{\log(L'/L)}+\cdots.\label{eq:z_fit}
\end{equation}
The equation above allows one to extract both $\omega_i$'s and $c_i$'s needed to obtain the scaling corrections in $\Delta(L)$. Note that we have explicitly suppressed the fact that the effective dynamic exponent as well as the finite size corrections are functions of $m_\mathrm{threshold}$. We will revisit this functional dependence in later sections, but it is important to recall our previous argument that in the limit $m_\mathrm{threshold}\rightarrow 0$, $z_\infty$ converges to the true dynamic exponent of the model.

In the following we will test this scaling hypotheses on two examples. First we study the Heisenberg antiferromagnetic on the simple square lattice. The low-energy physics of this model is very well understood and provides a good benchmark for our scaling approach~\cite{anderson52,d_fisher89,neuberger89,hasenfratz93}. We then go on to apply this method on the site-diluted Heisenberg antiferromagnet on a square lattice at the percolation point, where there have been previous studies but not as clear of a consensus as to the low energy physics of the model \cite{wang06,wang10,ghosh15}. To compute the imaginary-time evolution, we use a projector QMC method that in practice shares many similarities with the common Stochastic Series Expansion (SSE) method. We sample contributions to $\langle\psi_0|H^{2m}|\psi_0\rangle$ and define $\tau=m/N$ where $N$ is the total number of spins on the lattice. This time definition is equivalent, up to a factor, to the conventional imaginary-time appearing in the Schr\"odinger evolution operator~\cite{sandvik10,sandvik10_2}.

\section{Clean Heisenberg Antiferromagnet \label{sec:cleanheisenberg}}

For the first example we consider the standard two-dimensional (2D) antiferromagnetic Heisenberg model, defined by the Hamiltonian
\begin{equation}
H = J\sum_{\langle i,j\rangle} {\bf S}_i\cdot {\bf S}_j,
\end{equation}
where ${\bf S}_i$ is a spin-$1/2$ operator at lattice site $i$ and the sum is over nearest neighbors on an $L$ by $L$ square lattice in $D=2$ with periodic boundary conditions. We set $J=1$ for the rest of the paper. This model is a part of a broad class of antiferromagnet models on translationally-invariant bipartite lattices which are known to have quantum-rotor like low-energy excitations~\cite{anderson52}. These excited states have energy levels which become degenerate with the ground state in the limit $L\rightarrow\infty$ as a power law: $E_\mathrm{rotor}-E_\mathrm{GS}\sim L^{-z}$. Here $z=D$ is the dimension of the lattice and $L$ is the linear dimension of the system. One can think of these quantum rotor states as the quantization of the global angular fluctuations of the order parameter which in the thermodynamic limit form a basis in the ground state manifold used to create the symmetry broken ground state which is the vacuum of the gapless spinwave excitations \cite{d_fisher89,neuberger89,lavalle98,hasenfratz93}.
Fig.~\ref{fig:rotor}(a) shows $\langle m^z_s(\tau)\rangle$ versus $\tau$ for various system sizes. In this figure one clearly sees that initially all the system sizes relax at the same rate but then eventually break off from one another when the sublattice magnetization reaches $\langle m^z_s(\tau)\rangle\approx 0.3$, with the larger system sizes taking longer to relax to $\langle m^z_s(\tau)\rangle\rightarrow 0$. One may recall that in the ground state of this model the thermodynamic value of $\langle m^z_s(T=0)\rangle\approx 0.307$ \cite{sandvik97} which roughly corresponds to the value where the different system sizes begin to relax at different rates (see the dotted line in Fig~\ref{fig:rotor}).

One can make use of the continuum field theory description of the long wavelength behavior of this model to understand the evolution of the order parameter in imaginary-time. The lowest energy states of the continuum field theory are uniform in space. Since the initial state is also uniform, and the system is translationally invariant, the evolution will occur within the subspace of uniform configurations. The dynamics in this subspace simplify to that of a quantum particle relaxing in the ``Mexican hat'' potential. Here the probability distribution of the particle in space represents the probability distribution of order parameter of the system. Since the initial order parameter value is $0.5$, the initial probability distribution of the order parameter is localized away from the minimum of the potential which for the Heisenberg model on a square lattice is close to $0.3$, as illustrated schematically in Fig.~\ref{fig:density}($i$). As the system evolves in imaginary-time the energy of the system decreases and order parameter decays until it reaches the bottom of the potential which in the thermodynamic limit corresponds to the the symmetry broken "ground state", as in Fig.~\ref{fig:density}($ii$). However, because the system is finite, this is not a true ground state so the energy of the system continues to decay and the mean magnetization along the z-axis relaxes to $0$ as the probability distribution spreads out over all possible solid angles; Fig.~\ref{fig:density}($iii$). This second part of the relaxation is governed by the rotor state as they are the states which make up the quantization of the angular part of the order parameter (and sets the effective moment of inertia which scales as $L^D$,~\cite{anderson52,sandvik10}). We can confirm this intuition for the lattice model by observing that in Fig.~\ref{fig:rotor}(b), by rescaling the $\tau$ axis with $L^2$ one finds that the second section of the relaxation shows scaling collapse. A consequence of this is that in the limit $L\rightarrow\infty$ the order parameter never relaxes to $0$ implying that the system remains in the symmetry broken ground state.

Next let us discuss how to numerically extract the dynamic exponent from finite size data. First one must numerically determine the intersection points of $\langle m_s^z(\tau)\rangle$ with the threshold value $m_{\mathrm{threshold}}$ required to calculate the finite size exponent $z(L,L')$ between two system sizes. Here we choose $L$ and $L'=2L$, defining $z(L)\equiv z(L,2L)$. To extract $\tau_r$ we fill a window around the threshold with QMC data and then use a polynomial (or some other appropriate function) to interpolate the data and numerically find the crossing point of the interpolation and $m_\mathrm{threshold}$.

Next we must derive the finite size corrections to $z(L)$ which is dependent on the parameterization the finite size corrections in $\Delta(L)$. For this model it is natural to assume that $\Delta(L)$ should be an analytic function in $1/L$ because the model has no critical fluctuations. keeping terms up to order $L^{-3}$ in $\Delta(L)$ we find the finite size corrections to $z(L)$ are
\begin{multline}
z(L)=z_\infty+\frac{c_1}{2 \log (2)}\frac{1}{L}-\frac{3 \left(c_1^2-2 c_2\right)}{8 \log
   (2)}\frac{1}{L^2}\\+\frac{7 \left(c_1^3-3 c_2 c_1+3 c_3\right)}{24 \log (2)}\frac{1}{L^3}.\label{eq:Clean_fit}
\end{multline}
The extrapolated dynamic exponents are shown as a function $m_{\mathrm{threshold}}$ in Fig.~\ref{fig:clean_exp} (note that the values in Fig.~\ref{fig:clean_exp} are correlated because $m_\mathrm{threshold}$ values can be arbitrarily close to one another). The extrapolated values of  $z_\infty$ for low $m_\mathrm{threshold}$ are in excellent agreement with the analytic result of $z_\infty=2$. For higher values for $m_\mathrm{threshold}$ the disagreement is natural because at short times the many-body wavefunction still has an overlap with high-energy states. As the system evolves in imaginary-time (as $m_\mathrm{threshold}$ decreases), the overlap with these higher energy states decay and so their effects on the effective dynamic exponent vanish. The parameters $c_i$'s coming from the exponent flow give us the same coefficients which parameterize the finite size corrections of $\Delta(L)$. Figure \ref{fig:Clean_col}(a) focuses on the final relaxation time scale and more clearly shows the finite size corrections to $L^{-z}$. By including the finite size corrections calculated from the extrapolation, we find much better scaling collapse; see Fig.~\ref{fig:Clean_col}(b).

\section{Heisenberg Antiferromagnet on Fractal Clusters \label{sec:percolating}}

The second example has the same Heisenberg interactions with nearest neighbors as the previous section, but the boundaries are no longer periodic and spins on the sites are randomly removed from the lattice with probability $1-p$. This dilution is particularly interesting when it is set to the percolation point. It has been shown that at this dilution, the characteristics of the low energy states are different from that of the standard quantum rotor picture \cite{sandvik02,wang06,wang10,changlani13,ghosh15}. The volume of these clusters scale as $N_c\sim L^{D_f}$ where $D_f=91/48$ is the fractal dimension and $L$ is a linear size of the cluster \cite{stauffer94}. It has been conjectured that the low energy states of this model are dominated by a generalization of the ``dangling spin'' concept---local sub-lattice imbalance in a region of a given cluster \cite{wang06,wang10} where en effective moment forms due to the inability of spins to pair up in a bipartite manner. On a Bethe lattice geometry the same phenomena was studied using the DMRG method \cite{ghosh15}. In this study it was shown explicitly that there exists a set of low lying quasi-degenerate (QD) eigenstates which remain separated from the higher energy eigenstates by a finite size gap $\Delta_\mathrm{QD}$, which goes to 0 slower then the spacing between the QD states. It was conjectured that these QD states decouple from the bulk and because they are made up of power-law localized magnetic moments which interact with each other across the cluster, as had been previously deduced based on scaling behaviors of quantities probing the low-energy excitations indirectly \cite{wang06,wang10}. For this reason, diluted Heisenberg models have a larger dynamic exponent than predicted by the quantum rotor picture \cite{wang06,wang10,changlani13,ghosh15}.

Beyond the interesting physics of this model, the disorder should prove a more robust test of our scaling hypothesis and method for extracting the dynamic exponent. The major difference between this model and the last is the type of finite size corrections we see. In the unadulterated 2D case, the model is very far away from any sort of critical behavior and so the corrections are analytic in $L^{-1}$ but here we can not assume this as there are fluctuations driven by the classical percolation threshold \cite{sandvik02}. However, since we are only interested in extracting the dynamic exponent its perfectly reasonable to parameterize the finite size corrections to be analytic in $N^{-1}$, where $N$ is the number of sites making up a cluster.

\begin{figure}
	\includegraphics[width=0.45\textwidth]{Cluster_Collapse_fig.pdf}
	\caption{\label{fig:Cluster_col}
	Finite-size scaling analysis of $\langle m_s^z(\tau)\rangle$ in the Heisenberg model on a percolating cluster (averaged over dilution realizations). The black dotted line denotes the threshold value along which the curves are collapsed; $m_\mathrm{threshold}=0.02$.  (a) shows the data collapse with the leading behavior $N^{-z_\infty/D_f}$ used for rescaling the $x$-axis, with $z_\infty/D_f=2.065$. (b) shows the scaling collapse including finite-size correction to $\Delta(N)$ corresponding to the fit of the finite-size flow shown in the inset.}
\end{figure}

To perform the dilution averaging we employ a procedure similar to what is outlined in Ref.~\cite{sandvik02}. Each cluster is constructed with a fixed number of sites $N_c=L^{D_f}$ where we round up to an even integer to insure that the ground state can have total $S=0$. The finite-size scaling of the low energy gap is implemented in the following form:
\begin{equation}
\Delta(N)= N^{-z_\infty/D_f}(1+c_1 N^{-1} + c_2 N^{-2}+\cdots).
\end{equation}
The finite-size flow of the effective dynamic exponents are calculated between system sizes of length $L$ and $2L$, which implies $N'=2^{D_f}N$, for the cluster sizes. Keeping terms up to order $N^{-2}$ in finite size corrections to $\Delta(N)$ we obtain the following expansion for the finite-size effective dynamic exponent $z(N)$:
\begin{multline}
\frac{z(N)}{D_f}=\frac{z_\infty}{D_f}+\frac{c_1\left(2^{D_f}-1\right)}{2^{D_f} \log (2^{D_f})}\frac{1}{N}\\-\frac{3\left(2^{2D_f}-1\right) \left(c_1^2-2 c_2\right)}{2^{2D_f} \log
   (2^{D_f})}\frac{1}{N^2}.\label{eq:Cluster_fit}
\end{multline}
Results of a data-collapse analysis both with and without the scaling corrections are shown in Fig.~\ref{fig:Cluster_col}.

For our lowest value of $m_\mathrm{threshold}=0.02$, $z_\infty/D_f=2.056(8)$ or $z_\infty=3.90(1)$, slightly larger than what was found previous studies\cite{wang06,wang10}. Although we may have introduced some systematic error by assuming the finite size corrections decay as $1/N$, the inset in Fig.~\ref{fig:Cluster_col}(b) shows that for the largest system size ($N=714$), $z(N)/D_f \geq 2$. Because our system sizes are comparable to previous studies we know that this is not an issue of finite size effects. We also know that in imaginary-time evolution, the weights coming from an eigenstate $|n\rangle$ relaxes on a timescale of $\tau_n=1/(\epsilon_n-\epsilon_0)$, meaning that higher energy states always decay faster than low-energy states and therefore the effective dynamic exponents must be monotonically increasing as $m_\mathrm{threshold}\rightarrow 0$. This is consistent with results in the previous section and with the threshold dependence of the extrapolated dynamic exponent shown in Fig.~\ref{fig:cluster_exp}.

\section{Conclusion \label{summary}}

In summary we have shown that the relaxation of the order parameter in imaginary-time can be used to quantitatively extract low-energy properties of a given model. In particular, we have developed a scaling method which allows one to extract the dynamic exponent by performing scaling collapse of the order parameter along the imaginary-time axis. The imaginary-time evolution of the order parameter in a 2D Heisenberg antiferromagnets was used as a test-case to show that one can extract the correct dynamic exponent, which in this case is related to the Anderson tower of quantum rotor states. We also studied the relaxation of the order parameter of the corresponding site dilute Heisenberg antiferromagnet at its percolation threshold and found that the scaling theory gives a dynamic exponent even larger than seen in previous studies; $z=3.90$ versus $z\approx 3.7$ from Refs.~\cite{wang06,wang10}. These results conform with the notion that there is a set of low-energy states due to quasi-localized moments---``dangling spins'' and their generalizations to larger regions of local sublattice imbalance~\cite{wang06,wang10}.

As there are very clear numerical results that the ground state of the Heisenberg model on the percolating cluster does indeed have long range order~\cite{sandvik02}, there is still an open question if there is a quantum-rotor tower of states in these clusters, which presumably should be required for spontaneous breaking of the spin-rotation symmetry in the thermodynamic limit~\cite{anderson52,goldstone62}. If they do exist they would have relaxation times that would scale as $L^{D_f}$ according to the quantum rotor picture, however our method would not be able to isolate these states directly as it can only extract an effective dynamic exponent originating from the mixing of low and high energy states at short times.  The fact that we see a dynamic exponent with significant flow with the threshold value
of the mean order parameter in the system---much larger than in the unadulterated system---may in principle be an indication of the rotor states. However, the density of the rotor states should be much lower than the low-energy states arising from the quasi-localized moments. The drift in the exponent may therefore instead be related to a slowly changing dynamic exponent of these quasi-localized states as one goes to higher energies in their tower. We believe that this is the more likely scenario, with rotor states existing in the bulk of the cluster but not contributing significantly to the low-energy dynamics because of their much higher dynamic exponent and much lower density of states.

In this work we have only studied the spatially averaged order parameter but in the case of the percolating clusters it could be useful to look at the local order as a function of imaginary-time in a similar spirit as Refs.~\cite{wang06,wang10}. One would expect that if the localized spins are indeed decoupled from the bulk, that this would manifest itself as very different relaxation times between the localized moments and the bulk. One would even hope to see that the bulk relaxes to $0$ on time scales $\tau\sim L^{D_f}$ while the decoupled moments would relax on time scales of $L^{3.90}$.

The QMC methods used here to simulate imaginary-time can be generalized to higher spin representations which, along with other methods, would give a more complete picture as to the low energy excitations of the higher spin versions of the Heisenberg antiferromagnets on percolating clusters.

Q: Can I set the inner router to be the gateway? Question
Now I have two routers: A and B. The router A is connected to the Internet, and the router B is connected to the router A. Now can I configure something which makes the router A just offer Internet and the router B the gateway and dhcp?
Background
In practice, the router A is usually part of an advanced DSL modem without flexible interface to configure NAT, firewall, etc. I need take advantage of the router B to do network management.
I'm a layman and a newbie, so maybe I cannot understand technical nomenclatures. I hope the explanation to be elementary enough. Any idea? Thanks!

A: Yes and no. In order for your Internet router to provide connectivity to the Internet, it must be the gateway. In simple terms, a gateway links together two network segments that would otherwise be unable to communicate.
Technically your second router can provide DHCP services to your network, but it would need to tell clients that the other router is the default gateway. Most SOHO routers won't let you specify the gateway included in their DHCP leases, and if this is true of your second router then you won't be able to use it the way you envision.
You could connect the second router directly to the Internet router as the latter's only downstream node and connect all of your clients to the second router as you would normally, in which case the second router would be their default gateway, DHCP server, etc. But this is a bad idea. It adds unnecessary complexity without any useful gain, and half the time such a configuration doesn't work as intended.

The Cambridge International General Certificate of Secondary Education (IGCSE) is a popular international qualification for students aged 14-16. The IGCSE is designed to be taught as a two-year program. Each subject is certificated separately. Cambridge IGCSE is comparable to the Singapore-Cambridge GCE O-Level system and the United Kingdom's General Certificate of Secondary Education (GCSE).
1. The Curriculum
The IGCSE offers over 70 subjects, and the syllabus has both international and local elements. There are so many interesting subjects, such as Food and Nutrition, Travel and Tourism, and Design and Technology, to name a few. There are five subject groups:
1 Languages (First Language, Second Language, Foreign Language, etc)
2 Humanities and Social Sciences (Geography, English Literature, History, etc)
3 Sciences (Biology, Chemistry, Physics, etc)
4 Mathematics (Mathematics, Additional Mathematics, etc)
5 Creative, Technical & Vocational (Accounting, Business Studies, Computer Studies, etc)
2. Certification
IGCSE qualifications are recognised globally. A student is awarded one IGCSE certificate for each subject. In other words, if a student takes 5 IGCSE subjects, he or she will receive 5 IGCSE certificates.
3. Assessments
The IGCSE assessment is conducted at the end of the course. Assessments include written, oral, coursework, and practical assessment. This way, students are given the chance to exhibit their learning abilities. In many subjects, there is a choice between core and extended curricula. To prepare for these assessments, students can access the past papers that are available online.
4. Grading
Cambridge IGCSEs are graded A*-G around the world. The A*-G grading is used by more than 6,000 schools in over 145 countries. However, some schools in select regions use 9-1 grading. Under the 9-1 grading scheme, 9 is the top grade (equivalent to an A* in the A*-G grading scale). How do A*-G grades compare to 9-1 grades?
(From cambridgeinternational.org)
5. IGCSE Core and IGCSE Extended
A teacher, taking into consideration the different abilities of her student, decides the most appropriate levels of her students. Thus, for some subjects, there is a choice between Core and Extended curriculum papers. In general, the Core curriculum is deemed easier than that of the Extended. The grades range from C-G. The Extended curriculum, made up of the Core curriculum and the Supplement (the extra topics or depth which must be added to the Core curriculum to produce the Extended curriculum), is aimed at the more academically able and leads naturally into higher education or professional training. The grades range from A* to E. The overlap of grades C, D, and E is designed to accommodate students who perform either better or worse than what their teachers expect.

Maybe someone knows how to avoid this problem?

Did you know that the really first eating house in the universe was opened in Paris in 1765? A tavern keeper. Monsieur Boulanger. served a individual dish. sheep's pess simmered in a white sauce. Boulanger's concern was different from other nutrient concerns. like coffeehouse and hostel. because Boulanger's concern was centered on nutrient. non alcohol. like tap houses. or java and tea. like coffeehouse. Customers came to Boulanger's constitution chiefly to eat. and this was a freshness in the late eighteenth Century. where the population ate their repasts at place or. if they were off from place overnight on concern. at an hostel. Opening your ain eating house can be really complicated at the beginning but first you start making the right things. you can carry through your end. Everything in life has an order while doing things ; this besides includes get downing your ain eating house. You can non get down by engaging your employees if you don't even have the topographic point or the construct of your eating house. so the first thing you should make is take the construct of your eating house. Restaurants are classified into three primary classs: speedy service or fast nutrient. midscale and upscale. Fast nutrient offers limited bill of fare of points that are prepared rapidly and sold for a comparatively low monetary value.
The type of nutrient you could sell in a fast nutrient construct are chicken. hot Canis familiariss. sandwiches. pizza and all sort of nutrient that can be prepared in a lower limit of clip. That's why it is called "fast food" . Midscale eating houses occupy the in-between land between speedy service and upscale eating houses. They offer full repasts but charge monetary values that clients perceive as supplying good value. Midscale eating houses offer a scope of limited and full service options. Finally upscale eating houses offer full tabular array service and make non needfully advance their repasts as offering great value ; alternatively they focus on the quality of their culinary art and the atmosphere of their installations. The type of construct you will take will find your equipment demands. your type of table top points. storage. employee uniforms. how big of a edifice you will necessitate. how many employees you will necessitate to engage. your parking batch seize and what type of marks and type of advertisement needed. The following measure is taking the right name. it will assist you sell your merchandise. stick with your clients and act upon your decorating and advertisement. You will desire your clients to be able to retrieve you restaurant's name so it doesn't have to be complicated and long.
Where are you traveling to set your new eating house? Some of import things that you need to take into history are the traffic. visibleness. client parking installations. size of the topographic point. the monetary value. and its status. Now that you have all of the above. you can get down taking your equipment and seting monetary values to the bill of fare. The type of equipment you will necessitate depends on the construct of you restaurant ; if it is an upscale eating house you need more equipment than if you have a fast nutrient eating house. Besides the monetary values depend on it because one is cheaper than the other constructs. You need to do a list of the nutrient you will purchase and harmonizing to it do up your monetary values where you can hold net incomes but besides accessible to the clients. Your eating house demands to hold marks so your clients find it interesting. How you can do it? Well. the messages have to be short. easy to read and understand by people go throughing by ; alteration you sign's messages often ; utilize all capital letters and most of import look into your spelling and maintain it clean. It is the minute of the funniest and besides really of import portion. adorning your restaurant's inside.
You already know that your restaurant's interior design is one of the most indispensable facets of your business's presentation. The expression and feel of your concern is captured by the design of your dining room. It is the first thing most people notice when they enter your eating house. For a better consequence on it. you can engage person specialized in that country ; but you need to maintain in head the pigment strategies. artefacts. wall ornaments. image. architectural design. and illuming. Choosing employees who will make a good occupation is non merely of import to the success of your concern. but will besides lend to the image of your constitution. While engaging your employees you have to interview them and be certain to inquire all that you need to cognize to see if they have the profile you are inquiring for. Besides be certain that the payment is good plenty for them to accept the occupation. you should make research to happen out what the wage rates are in your country. You'll want to set up a minimal and maximal rate for each place. You'll wage more even at the start for better qualified and more experience workers.
There are several classs of forces in the eating house concern: director. cooks. waiters. waiter's assistants. dish washers. hosts and barmans. The wages vary depending on the occupation they are making. Every concern needs a selling program and the most effectual 1 is the word of oral cavity. People normally go to topographic points that have been recommended by household or friends. do your clients have a good experience in your eating house so they will desire to speak about it and reiterate the experience. Ask every client how they found out about you. and do notes so you notice what you need to alter or maintain ; another manner to advance your nutrient service is giving off gift certifications or vouchers. Get downing your ain eating house may sound really hard but it is non. you need to make things in order to do it work and be easier for you. There are a batch of things that you need to make. some are more of import than others but you need to take into history all of them because it is portion of it. It can be really amusing or emphasizing but it all depends on how you see things and the place you take while doing it.


We usually order the brisket. It is awesome. The baked beans are good too.
They also do catering. They catered my wedding reception with a roast pig and everything. It was amazing. I received so many compliments and the price was so much less than I expected. I would absolutely recommend them to anyone looking for a no hassle caterer.
My brother in law and sister came down her a few years ago. They had come through St. Louis and had eaten ribs at a place that was called something like America's Best Ribs. I took them to Sweetwater. He said the place in St. Louis needed to change their name. That Sweetwater had the best ribs he had ever tasted. Now keep in mind he was a biker, president of the BMW riders of America, and had been in every state plus Canada on his bike. So he has eaten a lot of different ribs. HE LOVED SWEETWATER My brother in law died two months after coming down here, so he never got to eat them again but my sister said he told her a couple times "wish I had some of those ribs." I like them too but I'm not crazy about their sides.
When they catered for you, did they supply the utensils and some type of drink, like tea or something? We are thinking about using them for an event in the near future. I was just curious.
I remember they did supply utensils. But I can't remember if we got tea or anything else to drink or not... but I do remember it was an option. The also give you the option to have them stay and serve the food, which was such a big help. Plus we had so much left over we had to send stuff home with people. Good luck on your event and I'm sure you'll be as satisfied with their product and service as we were.
Thank you for the information Tracy. I really appreciate it!
Has Sweetwater changed hands ? The last 3 times we have eaten there the food was awfull. The last brisket we got was just one large piece of fat. I used to love their food but not now.
And the one thing they i didnt understand was there sunday special. It was marked that they also had sliced brisket, cabbage, sweet potatoes, and a couple of other items. When i placed my order with one gal i got the cabbage as a side with wifes dinner. Another gal was taking orders from other people and wouldnt give them the cabbage as a side. Said the only way to get it was with the sunday special. The way the board was written i thought these were just extra items you could get, not that it was a sunday special.

Kim Beck's work urges a reconsideration of the built environment - the peculiar street signs, gas station banners, overgrown weeded lots, and self-storage buildings — bringing the banal and everyday into focus. For this exhibit, Beck works with primed linen to build security fences. Each fence is flawed with snags or buckles, reduced to collapsed grids or ineffective fragments, failing to protect. Part of a larger series of fences made of different materials, including a wall drawing, etching, stack of silkscreen prints on cardboard, digital prints and charcoal on paper.


Full-size, maximum resolution files - digital images - are available for download, or on a DVD or USB drive. Large prints are also available for sale.

The social sciences have a considerable history of attempts to apply models and theories from the physical sciences. All such attempts have failed, primarily because social scientists have commonly not distinguished between applications and possibly useful metaphors.Attempts to apply non-linear mathematics to social concerns will similarly fail. There are now no non-trivial applications, and there are unlikely ever to be.But the phenomenon of reifying models and theories from elsewhere has long standing status in the social sciences, and DDNS can play an important role in monitoring those attempts.


Fire can occur anytime without any notice. Loss of life is one among the many severe effects of fire outbreak. Fire outbreaks are always prevented by people. There are cases of fire outbreak even with the prevention by people. It is good to have fire sprinkler system in your building in case a fire outbreak occurs. Installation, maintenance, and servicing of a fire sprinkler system is the work of a fire sprinkler contractor. A good fire sprinkler contractor will ensure that your fire sprinkler system is properly installed, maintained and serviced. Discussed below are some of the factors to be considered before hiring a fire sprinkler contractor.
Work experience of the fire sprinkler contractor is a factor to be considered before hiring one. Work experience is directly proportional to the length of time one has worked. Someone who has experience in something has more knowledge on that specific thing. Something is done right by someone who is used to doing it. The best fire sprinkling systems installations, maintenance and servicing are done by experienced fire sprinkler contractors. Set fire safety regulations are known to an experienced fire sprinkler contractor and he or she obeys them. Former clients of the fire sprinkler contractor and referees will give you information on the experience of the fire sprinkler contractor. The success of the fire sprinkler contractor in his or her past projects should attract you to choosing him or her.
Consider the work reputation of a fire sprinkler before choosing him or her. What people say about a person is what he or she is. Hire someone who is relevant to your work as per their work reputation. Enquire for the fire sprinkler contractor's referees and clients from him or her. Ask the contractor's reputation from his or her past clients and referees. Ask the clients what they liked about the contractor and what they did not like. The knowledge given by the clients and referees will help you know what to expect from the contractor. A well-reputed fire sprinkler contractor should attract you to them.
A fire sprinkler contractor who can offer a wide range of services is the best. With such a fire sprinkler contractor, you will not need many contractors for different services. Coordination can be a problem when you have to coordinate many contractors, having one wide ranged contractor solves this. Less money is spent since only one contractor is paid. When choosing a fire sprinkler contractor, consider the above factors.

La estación posee tres andenes: el 1 y el 2 para el servicio ordinario y el 3, para maniobras generales. Adicionalmente, cuenta con dos vías auxiliares más. Un túnel peatonal comunica los 3 andenes con las boleterías, oficinas y baños públicos que se encuentran en el lado oeste de la estación
La estación se encuentra emplazada en Gaboto entre Rivadavia y Leandro N. Alem.

Estación provisoria
Unos 300 metros hacia el norte se encontraba ubicada una estación provisoria, conformada por dos andenes elevados que permitían el ascenso y descenso de las formaciones eléctricas puestas en marcha a partir de febrero de 2016. La misma  estuvo en funcionamiento hasta la mañana del 1º de junio de 2018. En los días subsiguientes las esctructuras fueron desmontadas. Entre febrero y junio de 2016, esta estación provisoria operó como terminal del servicio electrificado.

Historia
Fue inaugurada en 1872 por el Ferrocarril Buenos Aires al Puerto de la Ensenada. Contó con una sola vía hasta el año 1887, cuando se agregó una segunda. En 1898 el FCBAPE fue adquirido por el Ferrocarril del Sud, el cual la integró a su red y modernizó su edificio en 1908 de acuerdo a las necesidades y preferencias arquitectónicas de la época, dándole su aspecto actual. El diseño estuvo a cargo de los arquitectos Paul Bell Chambers, entre cuyas obras se encuentran la Estación Constitución, el Railway Building y el Banco de Boston, y Louis Newbery Thomas.

Al nacionalizarse los ferrocarriles y reorganizarse el sistema ferroviario en 1948, pasó a ser parte de la red del Ferrocarril General Roca.

Accidentes
El Accidente ferroviario de Quilmes de 1982, que dejó un saldo aproximado de treinta muertos, tuvo lugar unos 400 metros al sur de la estación.

Q: Equivalent of LaTeX "eqnarray" in Microsoft Word 2007 equation editor? In LaTeX one can use the eqnarray environment to display a set of equations aligned horizontally on their equality signs or other element, e.g.:
\begin{eqnarray*}
  x &=& 5! \\
    &=& 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1
\end{eqnarray*}

This will render as follows (notice the alignment of the equality signs):

Is there a good way to achieve the same effect in Microsoft Word 2007's built in equation editor?

A: What you're after is an "equation array", which is invoked in MS Equation Editor with \eqarray.
It's borrowed from LaTex.
Type Alt-= then:
\eqarray(x+1&=2@1+2+3+y&=z@3/x&=x) <space>

You'll get:

Nice!
As you can tell, an new line (equation) is started with @.  Within an equation, the &'s alternate between telling it what to align at and where to put the spaces needed to perform that alignment.  In the above example, there's only one & per line, so each is only telling Equation Editor which character to align at.
So this expression:
    \eqarray(10&x+&3&y=2@3&x+&13&y=4)
In the first equation we're saying "putting spaces before (implied) align at x.  And put spaces before 3 to align align at y".
We'll get this:

Apparently this ingenious (or ridiculous?) method comes from the Unicode standard.
As far as I can tell, you can't edit the alignment after you hit space and cause the rendering.  But, you can copy the equation, then paste it as text within the document and get the un-rendered code back.  Edit, go outside the parentheses and hit space, and your edited version is now rendered.
Undo also works to un-render it.
Note that you've always been able to select multiple equations, right-click, and "select at =".  This is less flexible, and in my experience, doesn't always work right.
[1] Reference

A: Not exactly, but this site has some good introductory material.  The equation editor is a bit more visual than latex:

Enter the following equations and align them at the = sign by choosing Format/Align At = after typing them. Also try using the alignment symbol -  - to align equations.


Despite his promises to "drain the swamp" and sweeping out the Barack Obama-era bureaucrats from all levels of the federal government, President Donald Trump and his administration have found it difficult to complete the process even after two months in office.
When President Trump's new Middle East envoy began haggling over the details of an agreement with Israel to curb construction of Jewish settlements in the West Bank, they turned to a politically improbable adviser: Yael Lempert, a 43-year-old diplomat who worked on the issue in Barack Obama's White House.
When Mr. Trump met with the leaders of Japan, Britain and Canada, he included Thomas A. Shannon Jr., another career diplomat, who rose to the No. 3 post in Mr. Obama's State Department. And when Secretary of State Rex W. Tillerson traveled to Turkey this past week to rally support for the military campaign against the Islamic State, he took along Brett H. McGurk, who coordinated that effort as Mr. Obama's special envoy.
These diplomats are part of a rare cohort in the Trump administration: holdovers from the Obama years, whose skills, knowledge and bureaucratic finesse have enabled them to survive, even thrive, in an administration determined to purge all vestiges of its predecessor.
Anytime there is a change in administrations, career government officials face a tricky transition. But that process has been particularly difficult under Mr. Trump, because of the insurgent nature of his campaign and his deep suspicion of the permanent bureaucracy.
