Founded in 1994, Rubber-Cal is a distributor of industrial rubber products. The company brings to market and inventories a wide range of rubber mats, rubber flooring, sheet rubber, flexible ducting, coir doormats, pavement maintenance parts and other specialty rubber products. Our large inventory and 24-hour fulfillment of stocked products makes us a great partner to agile OEMs and retailers by reducing their need to inventory parts and raw materials. Most of our rubber goods can be purchased in small custom-cut lengths, decreasing both the cost and time of installation and onsite fabrication.
Ingrained in our basic philosophy is the mission to offer "Green" products, whenever possible, to industry and consumers alike. Natural, reclaimed and recycled rubbers are not only a practical substitute but also a far more affordable option. Firstly, by using eco-friendly materials like natural and recycled rubber we help to reduce the presence of non-biodegradable rubber waste in the ecosystem. In the US, there are approximately 245 million tires discarded annually. Our products help reduce the presence of these tires in dumpsites. Secondly, consumers directly benefit from recycled rubber products because they are more affordable than their synthetic counterparts. This has been a distinguishing hallmark that has served Rubber-Cal well over the years. In fact, it is a point of pride for us. Products using eco-friendly recycled rubber, such as our interlocking rubber floor tiles, are very popular with consumers because they offer superior protection and durability at a competitive price.
Rubber-Cal's quality products have garnered attention for the company from the media. In 2016-17 you will see our products appearing on prime time TV shows such as Sweat Inc., The Biggest Loser, Strong, and Save Our Shelters. In the past ten years our rubber products have appeared on The Martha Stewart Show, ABC's Extreme Makeover: Home Edition, NBC's The Biggest Loser, US Open of Surfing, VH1's Money Hungry, Mr. Olympia, Designed to Sell, DIY TV's Run My Renovation, Extra Yardage, Man Caves and Grounds for Improvement. Rubber-Cal is proud to have been involved in the success of these shows. As the company continues to grow, consumers and industry can expect to see more of its products showcased in the media.
Rubber products can be complex and hard to understand. All of Rubber-Cal's success would not be possible without the dedicated expertise of its staff. Whether you need sheet rubber, rubber flooring, or custom-made rubber gaskets, our friendly and knowledgeable staff is on hand to help you find the right elastomer for your needs! The experts know that browsing through our product line may be intimidating for some, but they are here to guide you. With a firm belief in providing quality customer service, they make it their mission to educate and inform customers about rubber products.
Rubber-Cal is ushering in the New Year with a new product. Say hello to the Gas Station Mat! This rubber mat is the latest addition to our diverse catalog of rubber matting products.

What is the Best Basement Flooring?
Basements are versatile spaces in homes, with the ability to become anything from a bedroom or "man cave" to a game room or home fitness center. But if you plan to make the most out of your basement, the flooring will probably need an upgrade before the space is ready for use. There are many options for basement flooring, though most have concrete floors that can be cold, hazardous, and easily damaged. The versatility of the space can make it tricky to pick the best flooring for your needs, but luckily there are many rubber options for basement flooring that offer a competitive range of versatility.
With so many basement flooring choices, it is important to go with a material that offers enough protection—for both above the surface, and below it. Basement floors are prone to moisture, and even simple water can cause damage such as stains, mildew, and mold. Traditional concrete basement floors can also be damaged by heavy furniture or abrasive equipment—this is especially true for basements that are used as home gyms. This is why the flooring must be strong enough to protect not only your base floors, but any furniture or equipment on top.
Rubber is the ideal protective covering for basement floors because it absorbs impacts and vibrations, distributing the movement evenly to maintain a stable surface. Any abrasions caused by furniture and workout equipment are absorbed by the rubber to ensure it never reaches the subfloor. Rubber also has great resistances to moisture and temperature as well as natural traction-enhancing abilities, making it the best basement flooring across the board. With so many varieties available, there is a rubber floor to fit the function of each and every basement. Whether used for storage, fitness, or an extra bedroom—any remodeled basement can benefit from installation of rubber flooring.
In today's world, our pets are like our children, so naturally we want nothing less than the very best living conditions for them. With your dogs' health and happiness of utmost priority, why would you settle for a less-than-luxurious dog kennel? The best way to guarantee a space your pups love is by building a kennel yourself. Do-it-Yourself dog kennels are a fun and easy project that allow you to fully customize the space your furry friends inhabit. With a DIY kennel, you can avoid the concrete or dirt floorings that come with most kennels and ensure your pets always have a comfortable place to lay. Though there are many variations to choose from, rubber is typically the best kennel flooring across the board. No other kennel flooring material offers the same durability, comfort, and protection that rubber does. Your kennel should prioritize the animals' health, comfort, and happiness, and rubber flooring does that in a number of different ways.
Building a dog kennel is a great opportunity to skip out on hard concrete or dirt floors and instead provide your pups with an extremely forgiving surface. Rubber has natural elasticity, giving the flooring the ability to cushion around weight and provide anti-fatigue qualities. Another key benefit of rubber flooring is the superior level of protection. Rubber flooring is known for excellent abrasion, impact, and moisture resistances that make it great for most high-stress applications. Rubber kennel flooring options come in various thicknesses and durometers so you can pick out the perfect level of protection and comfort for your pets.
DIY dog kennels are an excellent way to show your pets some long-term love and affection. By creating a warm and comfortable space, you can make your dogs feel like they have a home rather than a prison cell. Rubber protects their sensitive paws from extreme conditions, regulates temperature, and provides ant-fatigue comfort to keep your furry family in good health for years to come.
When working with foam or sponge rubber, it is important to carefully plan each move to avoid ruining the material. Working with it before you properly know how to cut sponge rubber can have disastrous results and cost quite a bit in wasted material. Depending on your budget and the intended application, there are a few different methods of cutting foam rubber to consider. While many like to go for a cost-effective DIY approach, certain projects benefit more from custom foam cutting services with a die cutter, waterjet, or laser cutter. These rubber cutting tools vary in pricing, precision, and production rates, so you should carefully consider all factors when deciding on the right method to cut foam rubber for your project.
DIY: The do-it-yourself method is the most affordable, but also the messiest. A utility knife is a great option if you don't mind imperfect cuts. These methods are a great way to skip out on pricey custom cutting services, but in turn you can expect wavy edges and a lack of precision if you're cutting the sponge yourself.
Die Cut: Die cutting is a popular way to cut foam rubber due to its excellent precision. This process works much like a large-scale cookie cutter, in which the foam is forced down over serrated blades in a shape of your choice. Die cutting in basic shapes is fast and works well for bulk production.
Waterjet & Laser Cutting: The most precise method of cutting foam rubber is also the most expensive option—but it's worth it. Waterjet and Laser Cutters work in similar ways and both achieve highly-detailed cuts. The material is cut with either lasers or high-pressure streams of water, depending on the chosen method. These methods are without a doubt the best ways to cut foam rubber, especially for detailed applications and mass production.

The Essential Dylan Thomas
Read by Richard Burton, Philip Madoc, Richard Bebb & Jason Hughes
This varied, well-chosen selection brings onto one CD set the best of Dylan Thomas. Here is the legendary recording of Under Milk Wood, with Richard Burton and Richard Bebb as narrators; but here also are two radio productions he wrote before that great classic, and though interesting in their own right, they show how Under Milk Wood grew gradually in his imagination. Thomas was a charismatic if idiosyncratic performer of his own poetry and stories and here is a representative selection. Performances of Dylan Thomas have since moved on and the greatness of the writer as a poet and storyteller are perhaps best heard in new recordings by actors of our own time. Here Bebb, Madoc, and Hughes share some of Thomas's finest, most challenging and endearing works.

Born in London in 1927, Richard Bebb was educated at Highgate School and Trinity College, Cambridge. He became an actor in 1947 in Michael Redgrave's Macbeth and then spent two years in repertory at Buxton and Croydon, where he met his future wife, the late Gwen Watford. They married in 1952 and had two sons. From 1950 he worked regularly in all the theatrical media. He has appeared in a handful of West End plays, made over a thousand broadcasts, including sharing the narration with Richard Burton in the BBC recording of Dylan Thomas's Under Milk Wood and also appeared in almost two hundred television plays, including Alan Bennett's A Question of Attribution; among other television appearances were Barchester Towers and Agatha Christie's A Murder Has Been Announced. His one important film appearance was as the successful cricketer in Terence Rattigan's The Final Test. He owns the largest collection of historic 78s of opera singers in England and has lectured at Yale, Harvard, Princetown and the Smithsonion on theatrical and musical subjects. He discovered the unknown cylinder recordings of Sir Henry Irving.

As an owner of a car, I get myself turning into intelligent on the subject of automotive cabling. Since I am nearly the past individual who should be having fun with any situation that has electro-mechanical latest working via it, I was reluctant to attempt to take on the situation of automotive cabling.
Even so my vehicle made a decision normally when it did start to randomly decide on electro-mechanical devices that it desired to me tamper with. When the electrically powered seat belts did start to glide back again and forth without having factor as I drove downwards the highway, I chose I far better work out how to tamper with the electrically powered devices, considering the exuberant speed of automotive repair service.
I stumbled upon myself with a selection to either, disintegrate and devote $100 sixty minutes for a so-known as expert to think about it and attempt to maintenance it, or I could possibly discover how the electrical process of my car worked well. Thinking about my point of ignorance I perhaps was going to attempt to overcome the out of the question. Of course the only factor I knew about electrical systems is that AC/DC was a rock and roll ring and that dummies and wires commonly failed to go along.
Even so despite my reluctance, I lay out to understand the things i could about auto wires. I promptly found out that there is a large supply of data on the subject of auto wires. A swift explore Search engines given me by having an array of data. There are various quantities of web sites offering data.
Some web sites given a primary introduction of the normal electrical process of most cars. A company known as Lengthy Island Customs offered some fantastic primary data. They said that the data was simply just for a primary realizing and not for a comprehensive clarification of unique models. Yet they basically give some in depth facts about primary systems these types of as AC and lighting effects. Additionally, they give some fantastic difficulty photographing data.

I had published entire report about my blog for the year 2012 and it received great response. Also it helped me reflect on how this blog was doing and how could I make this blog better. So, I am making this a monthly event and would publish Traffic and earning report after every month end.
Around 41 thousand people visited Apnaplan.com in January 2013 leading to around 71 thousand page views.
I had set up target of 1 Million page views for 2013. To reach that I need average monthly page view of around 85,000. I was short of this target this month but good thing is it is 33% more from December. I hope it turns out better for next month.
Apnaplan.com got about 87% of traffic from search engines. This is same as it was for earlier months and is good news. Below is the breakup of traffic sources.
I had written 41 posts on ApnaPlan.com in January 2013. I am satisfied by this and hope to continue with the same pace.
The Alexa traffic Rank as of today is 136,356, while the website is ranked 14,894 in India. This is good for 21 month old blog.
As of today there are 1,121 subscribers using feedburner. Its a good news as we added 255 subscribers this month. The Facebook page of Apnaplan.com has 108 Likes. This month 18 new readers liked us. Its encouraging but I am surely looking for more :).
As of today I have only Infolinks on the site. As I said earlier, this is not a great revenue generator and has generated USD 41 in Jan 2013. I had removed Infolinks for a week to check how it impacted the traffic, readership experience, etc. I would soon publish my findings on the same.
Also I got $ 40 in direct advertisement.
So the total earning for Jan 2013 was $ 81.
I applied for Google Adsense but was denied citing the following reason – "site does not comply with google policies".
The reason is as vague as it can be and I tried looking for answers but am not able to fix this till now. If anyone can help me let me know.

Home Infrastructure In a first, Welspun One Logistics Park launches Alternate Investment Fund for...
In a first, Welspun One Logistics Park launches Alternate Investment Fund for domestic investors
Welspun One Logistics Parks, the pan-India integrated fund, development and asset management platform backed by the $2.7 billion Welspun Group, announced the launch of its first Alternate Investment Fund (AIF) product Welspun One Logistics Parks Fund I.
Sanctum Wealth Management and Edelweiss Wealth Management are on board as the key distributors of the AIF.
The fund, a SEBI-registered Category II AIF, is India's first warehousing fund that provides domestic institutions, HNIs, family offices and NRIs, an opportunity to invest in the booming warehousing and industrial real estate sector in India, the company says.
The fund has a target size of $500 crore with a tenure of 4 years and a hurdle rate of 15 percent. It has a significant commitment from the Welspun promoter family office of $75 crore. The investment thesis of the fund is to acquire land parcels in high demand, pre-identified markets, and develop Grade-A warehousing parks which will be leased on a long-term basis to 'AAA' credit tenants from sectors such as e-commerce, FMCG, third-party logistics (3PLs), pharma and auto-ancillaries. On completion, these assets would be divested to institutional investors including private equity, pension and sovereign funds, REITs, etc. so as to provide an exit and deliver the targeted returns to the fund investors.
BK Goenka, Chairman, Welspun Group said, "India's logistics sector will continue to be the backbone of economic growth and warehousing is a key component of this ecosystem. Presently, domestic investors can only invest in this high growth sector by investing directly in warehouses. Through this AIF, the investor can reap the benefits of the returns by owning units of a fund, instead of an asset."
Anshul Singhal, Managing Director, Welspun One Logistics Parks said, "Our business model of an integrated fund, development and asset management platform ensures that there is control over the entire lifecycle of the investment including land acquisition, leasing, development and divestment."
"Welspun One's investment strategy is focused around identifying tenant requirements and constructing built-to-suit warehouses to de-risk the investment. The team has spent the last 12 months creating a strong deal pipeline, with visibility on the deployment of a significant portion of the fund corpus. This includes our under-construction flagship 110-acre park with a leasable area of approximately 3 million sq ft in Bhiwandi, Maharashtra, which is already significantly pre-leased. In total, we expect to be able to deliver a portfolio of 6-7 million sq ft of Grade A warehousing space over the next 3-4 years," Singhal added.
Shiv Gupta, CEO, Sanctum Wealth said, "High structural demand, low vacancies, and a shorter development period relative to other real estate asset classes, combined with attractive returns and stable long-term yields have made the warehousing sector's risk-reward dynamics very favourable for investors looking to add higher-return assets to their portfolios."
Nitin Jain, CEO, Edelweiss Wealth Management said, "One of the big shifts of this 2030 decade would be the growth that India shall witness in infrastructure especially in logistics across the country. Mainly due to favourable government policies, consolidation, e-commerce and largely the market getting organised."
"The total penetration of warehouses in India is less than 0.1 sq ft per capita and the sector is expected to grow in excess of 20 percent CAGR. Welspun One's AIF is a first of its kind, launched to leverage the large opportunity in the sector, with an inherent strategy to mitigate due risks while giving stable long term returns to investors. We are happy to partner with them and believe that this is an opportunity for our customers to participate in the development of the Indian warehousing sector by investing in this fund," Jain added.

After your Saturday morning coffee and a pancake breakfast with the kids, perhaps you pick up a list of chores. Perhaps you stare at these tasks, each of them daunting in its own way, and pin the list back under the magnet on the fridge as you turn to the coffee maker for another cup.
But what if you had AI to help you know which tasks really needed to be crossed off that list? What if they were ranked by letter grades from A to F, each grade representing the balance of work required to finish the task versus the benefits of getting it done? Suddenly that endless list wouldn't look so daunting and you'd know where to get started right away.

\section{Introduction}

Theories of strings and branes have shown much promise as theories unifying
gravity with strong, weak and electromagnetic interactions. One limitation
has been that most of the work on these theories has been performed on the
classical theories. The most promising way to produce quantum theories of
strings and branes has been to study field theories which describe their
dynamics. The field theories which arise most naturally in this context are
Born-Infeld non-linear electrodynamics \cite{Born:1934,Born:1934gh}
and its extensions. Early papers which use Born-Infeld theories to describe the
dynamics of strings and branes include \cite{Fradkin:1985qd,Leigh:1989jq,
Aganagic:1996nn,Gibbons:1997xz,Tseytlin:1999dj}. However, since much of the
interesting physics arising from the non-linearities in Born-Infeld models is
inaccessible to perturbation theory, most of the work on these theories has
also been limited to the classical domain \cite{Callan:1997kz,Gibbons:1997xz}
or to the small quantum fluctuations \cite{Rey:1998ik} around these classical
solutions. Beyond this, there have only been a few exploratory investigations
of the general problem of quantizing this theory, for example
\cite{Hotta:2004zj}, which examines quantum solutions representing propagation
in a fixed direction.

Born-Infeld electrodynamics in $n+1$ dimensions is described by the non-linear
action
\begin{equation}
S = b^2 \int d^{n+1}x\,\left[1-\sqrt{-\det\left(g_{\mu\nu}+
\frac{1}{b}F_{\mu\nu}\right)}\,\right].
\label{eqn:Sminkowski}
\end{equation}
To make the connection with strings and branes, one typically chooses $n=9$
and dimensionally reduces the theory from $9+1$ down to $p+1$ dimensions. This
describes a $p$-brane, and the extra $9-p$ components of $A_\mu$ are
identified with the transverse degrees of freedom of the brane. The special
case $p=1$ describes a string. Here the non-linearity parameter $b$ is related
to the string tension through $1/b=2\pi\alpha'$.

In this work we study the original Born-Infeld theory in $3+1$ dimensions
($n=3$) with no dimensional reduction. In brane language we study a $3$-brane
with no transverse dimensions. This theory was originally proposed as a
modification of QED in which the electric field of a static point particle
was screened at short distances, rendering the self-energy of a point particle
finite \cite{Born:1934,Born:1934gh}.

We note that, in Euclidean space, the action is positive so that quantization
by the standard functional integral techniques is well defined. We then define
this theory on a discrete space-time lattice, preserving gauge invariance. The
positivity of the action allows the use of Metropolis Monte-Carlo
\cite{Metropolis:1953am} simulations to extract the properties of the quantum
field theory. In particular, we measure the electromagnetic fields produced by
a static point charge by including the effects of a Wilson Line (Polyakov
Loop) in the action. This destroys the positivity, but we are able to use the
methods of L\"{u}scher and Weisz \cite{Luscher:2001up} (after Parisi,
Petronzio and Rapuano \cite{Parisi:1983hm}) to produce the exponential
statistics required to overcome this lack of positivity.

We have performed simulations of the lattice Born-Infeld theory on $8^4$ and
$12^4$ lattices. We present evidence that the ${\bf D}$ field emanating from a
point charge is identical with that of the Maxwell theory, for all values of
$b$, up to lattice artifacts. The ${\bf E}$ field shows short-distance screening
as for the classical theory, but whereas classically the screening length
increases without limit as $b \rightarrow 0$, the quantum field theory
approaches a conformal field theory in this limit. In addition, the ${\bf E}$
field is enhanced over its classical value by quantum fluctuations. Preliminary
results for the smaller lattice were presented at Lattice 2005, Dublin
\cite{Sinclair:2005yw}.

In section 2 we summarise the salient features of the classical theory from
the extensive literature on Born-Infeld electrodynamics. Section 3 discusses
the lattice formulation in Euclidean space and simulation methods. We present
the results of our simulations in section 4. These results are discussed and
conclusions drawn in section 5.

\section{Classical Born-Infeld electrodynamics}

In this section we summarise those results from the literature on the classical
Born-Infeld theory in $3+1$ dimensional Minkowski space which are relevant to
our investigations. These results are condensed from the following references
\cite{Bialynicki-Birula:1984tx,Chruscinski:1997pe,Chruscinski:1997jd,%
Chruscinski:1998uw}. Evaluating the determinant in equation
\ref{eqn:Sminkowski} leads to the Lagrangian
\begin{eqnarray}
{\cal L} &=& b^2 \left[1-\sqrt{1+\frac{1}{2b^2}F_{\mu\nu}F^{\mu\nu}-
\frac{1}{16b^4}(F_{\mu\nu}\tilde{F}^{\mu\nu})^2}\right]     \nonumber      \\
&=& b^2 \left[1-\sqrt{1-b^{-2}(\bm{E}^2-\bm{B}^2)-b^{-4}(\bm{E \cdot B})^2}
\right].
\end{eqnarray}
Note that the requirement that the argument of the square root be positive,
restricts the magnitude of ${\bf E}$ which in turn gives rise to short-distance
screening and leads to a finite self energy for a point charge. This was the
original reason Born and Infeld proposed this non-linear extension of
electrodynamics. When dimensionally reduced Born-Infeld theories are used to
describe strings or branes, this same mechanism restricts the energy density of
the string/brane to be finite.

To proceed, it is customary to define ${\bf D}$ and ${\bf H}$ fields by
\begin{eqnarray}
\bm{D} &=& {\partial{\cal L} \over \partial\bm{E}} =
               {\bm{E}+b^{-2}(\bm{E\cdot B})\bm{B} \over
               \sqrt{1-b^{-2}(\bm{E}^2-\bm{B}^2)-b^{-4}(\bm{E\cdot B})^2}}
\nonumber \\
\bm{H} &=& {\partial{\cal L} \over \partial\bm{B}} =
               {\bm{B}-b^{-2}(\bm{E\cdot B})\bm{E} \over
               \sqrt{1-b^{-2}(\bm{E}^2-\bm{B}^2)-b^{-4}(\bm{E\cdot B})^2}}.
\label{eqn:DH}
\end{eqnarray}
In terms of ${\bf E}$, ${\bf D}$, ${\bf B}$ and ${\bf H}$, the field equations
are the standard Maxwell equations
\begin{eqnarray}
\nabla \bm{\cdot D} & = & \rho     \nonumber                                \\
\nabla \bm{\cdot B} & = & 0        \nonumber                                \\
\nabla \times \bm{E} + {\partial \bm{B} \over \partial t} & = & \bm{0}
\nonumber \\
\nabla \times \bm{H} - {\partial \bm{D} \over \partial t} & = & \bm{j},
\end{eqnarray}
where, as usual, the interaction with the electromagnetic current $j_\mu$ is
introduced by adding a term $j^\mu A_\mu$ to the Lagrangian. All the
non-linearity is hidden in the defining relations of equations~\ref{eqn:DH}.

For a static point charge $\rho=e\delta^3(\bm{r})$,
$\nabla \bm{\cdot D} = \rho$ has the spherically symmetric solution
\begin{equation}
\bm{D}={e \over 4\pi r^3}\bm{r}
\end{equation}
as for the Maxwell case. $\bm{B}=\bm{H}=\bm{0}$ and equations~\ref{eqn:DH} then
yield
\begin{equation}
\bm{E}={e \over 4\pi r}{\bm{r} \over \sqrt{r^4+r_0^4}}
\end{equation}
where
\begin{equation}
r_0=\sqrt{|e| \over 4\pi b}
\end{equation}
defines the screening length. Due to this short distance screening, the electric
field at the origin has magnitude $b$ rather than being infinite, and the energy
in the field of the point charge is finite.

\section{Euclidean Born-Infeld electrodynamics on a lattice}

In Euclidean space, the Born-Infeld action is
\begin{eqnarray}
S &=& b^2\int d^4x \left[\sqrt{1+\frac{1}{2b^2}F_{\mu\nu}F_{\mu\nu}+
     \frac{1}{16b^4}(F_{\mu\nu}\tilde{F}_{\mu\nu})^2}-1\right] \nonumber     \\
  &=& b^2\int d^4x \left[\sqrt{1+b^{-2}(\bm{E}^2+\bm{B}^2)
                         +b^{-4}(\bm{E \cdot B})^2}-1\right].
\end{eqnarray}
We note that this action is positive, so this theory can be simulated using
importance sampling methods. The expressions for ${\bf D}$ and ${\bf H}$ are
identical to those of equations~\ref{eqn:DH}, except that all signs are
positive.

To enable simulations, we must first transcribe this field theory to a discrete
space-time lattice. We choose a hypercubic lattice with lattice spacing $a$.
For convenience we define $\beta=b^2a^4$. From now on we will work in lattice
units where $a$ is set to $1$, except where we discuss the effects of varying
$a$. Because power counting suggests this theory is non-renormalizable, it is
generally considered as an effective theory, requiring a cutoff. Hence we are
not required to take the $a \rightarrow 0$ limit. We shall have more to say
about this later.

We choose the non-compact formulation of QED on the lattice, since this is
closest to continuum QED (In the Maxwell case it defines a solvable, free field
theory, as in the continuum). This is done by defining the lattice $F_{\mu\nu}$
by
\begin{equation}
F_{\mu\nu}(x+{\textstyle \frac{1}{2}}\hat{\mu}
            +{\textstyle \frac{1}{2}}\hat{\nu})
= A_\nu(x+\hat{\mu})-A_\nu(x)-A_\mu(x+\hat{\nu})+A_\mu(x),
\end{equation}
which is gauge invariant as is the continuum $F_{\mu\nu}$. This indicates the
first subtlety; $F_{\mu\nu}$ is not associated with a single site $x$ or link
of the original lattice. Therefore to preserve the symmetries of the cubic
lattice we average our action over the 16 choices of $6$ plaquettes associated
with a lattice site. These 16 choices are defined by choosing 1 unit vector in
each of the 4 directions emanating from the site, in all possible ways. The
set of plaquettes associated with a given choice of unit vectors is uniquely
defined by requiring that 2 edges of each plaquette belong to the chosen set
of unit vectors. Simulations are performed using Metropolis Monte-Carlo
updates of the gauge fields ($A_\mu$) on each of the links of the lattice. We
periodically perform subtractions of constant fields from each $A_\mu$, since
such constant fields have no physics, to prevent the lattice average of $A_\mu$
becoming too large. Similarly, we periodically gauge-fix these fields to Landau
gauge, to remove large gauge fluctuations.

To compare with the classical Born-Infeld results we need to measure the
${\bf E}$ and ${\bf D}$ fields for a point charge. Since we use periodic
boundary conditions on the gauge fields, the total charge on the lattice must
be zero. We choose the `Jellium' solution from condensed matter physics to
circumvent this difficulty. Here, if the magnitude of the point charge is $e$,
we distribute a charge $-e$ uniformly over the lattice. Hence each site
has charge $-e/{\cal V}$ (${\cal V}=N_xN_yN_z$ is the spatial volume of the
lattice), except for that site containing the point charge, whose charge is now
reduced to $e-e/{\cal V}$. On the lattice this charge is introduced by
including a Wilson Line (Polyakov loop) $W(\bm{x})$ in the functional integral.
\begin{equation}
W(\bm{x}) = \exp\left\{i e \sum_t \left[A_4(\bm{x},t)
          - \frac{1}{\cal V}\sum_{\bm{y}} A_4(\bm{y},t)\right]\right\}.
\end{equation}
We calculate the $\langle\bm{E}\rangle$ and $\langle\bm{D}\rangle$ due to this
charge as
\begin{eqnarray}
i \langle\bm{E}\rangle_\rho (\bm{y}-\bm{x}) &=&
{\langle\bm{E}(\bm{y},t)W(\bm{x})\rangle \over \langle W(\bm{x})\rangle}
\nonumber \\
i \langle\bm{D}\rangle_\rho (\bm{y}-\bm{x}) &=&
{\langle\bm{D}(\bm{y},t)W(\bm{x})\rangle \over \langle W(\bm{x})\rangle}.
\label{eqn:expect}
\end{eqnarray}
where the $i$ converts our electric fields from Euclidean space to Minkowski
space, and we use the subscript $\rho$ to denote the expectation value in the
presence of charge density $\rho$.

The Wilson Line for fixed ${\bf x}$ on any given configuration has magnitude
one, so
\begin{equation}
\langle |W(\bm{x})|\rangle = 1,
\end{equation}
while it is expected that
\begin{equation}
\langle W(\bm{x}) \rangle = e^{-const\: N_t}.
\end{equation}
This indicates that the phase of $W$ causes important cancellations between
the Wilson lines for different configurations in our ensemble. Hence we have
a sign problem. Averaging over the site ${\bf x}$ helps improve our statistics.
Even if we measured the Wilson line averaged over all sites, every sweep, we
will run into trouble if
\begin{equation}
\langle W(\bm{x})\rangle\lesssim 1/\sqrt{(number\: of\: sweeps \times {\cal V}},
\label{eqn:statistics}
\end{equation}
in the most optimistic scenario where the phases of the Wilson lines on a given
configuration are uncorrelated as are those on consecutive sweeps.
For any of our $12^4$ runs, the number of sweeps is 500,000 and ${\cal V}=1728$
and the right hand side of equation~\ref{eqn:statistics} is
$\approx 3.4 \times 10^{-5}$. As we shall see later, we really need to do
better.

L\"{u}scher and Weisz \cite{Luscher:2001up} (following Parisi, Petronzio and
Rapuano \cite{Parisi:1983hm} ) have pointed out that one can effectively
enhance ones statistics by dividing the lattice into some number (call it $n$)
of timeslices. Notice that, if one fixes the link fields on the boundaries of
these timeslices, the Monte Carlo updates of those fields on the interiors of
each slice are independent of the updates of the interiors of all other
slices. Thus if one performs $m$ updates of the interior of each time-slice,
it is equivalent to performing $m^n$ (restricted) updates of the lattice. In
addition this process can be performed recursively over progressively coarser
slicings of the lattice. In practice we have used thickness $1$ and $2$ time
slices recursively.

Let us now examine the limiting cases, first where $b \rightarrow \infty$, and
second where $b \rightarrow 0$. As $b \rightarrow \infty$, the Euclidean
Lagrangian approaches its Maxwell (free field) form
\begin{equation}
{\cal L}_E = \frac{1}{2}(\bm{E}^2 + \bm{B}^2).
\end{equation}
In the limit $b \rightarrow 0$ the Euclidean Lagrangian approaches the limiting
form
\begin{equation}
{\cal L}_E = |\bm{E\cdot B}|,
\label{eqn:limit}
\end{equation}
which describes a 4-dimensional conformal field theory. [Note that the
Minkowski Lagrangian (equation~\ref{eqn:Sminkowski}) does not exist in this
limit. However, the Hamiltonian formulation is valid in this limit, and leads
to the Hamiltonian
\begin{equation}
{\cal H} = |\bm{D}\times \bm{B}|,
\end{equation}
which also describes a conformal field theory
\cite{Bialynicki-Birula:1984tx,Chruscinski:2000zm}.]

\section{Simulation details and results}

We have simulated lattice Born-Infeld QED on $8^4$ and $12^4$ lattices. On
both $8^4$ and $12^4$ lattices we performed runs of 500,000 10-hit Metropolis
sweeps of the lattice at each of $\beta=0.0001,0.01,1,100$. On the $8^4$
lattice we ran an additional 100,000 sweeps at each of $\beta=0.1,0.2,0.5,2,5$.
Measurements were made every 100 sweeps. On the $8^4$ lattices the Wilson lines
and the on-axis fields they produced were measured in the L\"{u}scher-Weisz
scheme where we used 10 10-hit Metropolis updates of the interiors of each
thickness-1 timeslice for each of 10 10-hit Metropolis updates of the
interiors of each thickness-2 timeslice. For the $12^4$ lattice we increased
the number of updates at each level to 20. This means that we effectively used
$10^{12}$ configurations every 100 sweeps for our $8^4$ lattice simulations and
$2.62144 \times 10^{23}$ configurations every 100 sweeps for our $12^4$ runs,
for our measurements of the Wilson lines and electric fields. Admittedly these
configurations generated in the L\"{u}scher-Weisz scheme are not all
independent.

\begin{figure}[htb]
\epsfxsize=6in
\centerline{\epsffile{energy.ps}}
\caption{Euclidean action density $\langle S \rangle/V$ as a function of
$\beta$}
\label{fig:energy}
\end{figure}

In figure~\ref{fig:energy} we present the average action density
$\langle S \rangle/V$, where $V$ is the space-time volume, as a function of
$\beta=b^2a^4$ for our runs on both $8^4$ and $12^4$ lattices. We notice that
there is good agreement between the 2 lattice sizes, indicating that that the
finite volume effects are small. As $\beta \rightarrow \infty$, where the
theory becomes the linear Maxwell theory, the equipartition theorem predicts
that the action density is $\frac{3}{2}$. We note that the action density is
within a percent of this value by $\beta=100$, indicating that for $\beta
\gtrsim 100$ the theory is close to the Maxwell theory. In the
$\beta \rightarrow 0$ limit the scaling properties of the action again lead to
an action density of $\frac{3}{2}$. We see that our $\beta=0.0001$ action
density is very close to this value, while the $\beta=0.01$ value is only a
little over $2\%$ higher. This suggests that lattice Born-Infeld QED is close
to the limit described by equation~\ref{eqn:limit} for $\beta \lesssim 0.01$.
[Note that, because the zero modes do not contribute to the action, the
limiting values ($\frac{3}{2}$) have corrections ${\cal O}(1/V)$]. In between
the 2 limits the action rises to a maximum of magnitude $<2$ for $\beta \sim 1$.

of $\beta=a^4 b^2$ values: a) $8^4$ lattice: b) $12^4$ lattice.}
\label{fig:wilson}
\end{figure}

Figure~\ref{fig:wilson} shows the Wilson Lines as functions of electric charge
$e$ for 16 values of this charge ranging from $0.0078125$ to $4.0$ and for
the 4 beta values $\beta=0.0001,0.01,1.0,100.0$. At each $\beta$,
$\langle W \rangle$ starts from $1$ at $e=0$, and falls faster than
exponentially with charge $e$ as $e$ is increased. The falloff becomes faster
as $\beta$ (or $b$) is decreased, and the field theory becomes more non-linear.
We note, however, that the values of the Wilson lines for $\beta=0.0001$ and
$\beta=0.01$ are almost identical. This is further evidence that the theory
is close to the $\beta=0$ theory for $\beta \lesssim 0.01$. This also gives us
the first evidence for differences between the electrostatics of the quantum
and classical theories. Classical electrostatics has ${\bf B}$ and ${\bf H}$
identically zero, the contribution of equation~\ref{eqn:limit} vanishes and
the argument the square root of equation~\ref{eqn:Sminkowski} reduces to
$1-b^{-2}\bm{E}^2$ for all $b$. In the quantum theory it is not even
consistent to set ${\bf B}=0$, and the result is that the action still reduces
to the $b$($\beta$) independent form of equation~\ref{eqn:limit} as
$b \rightarrow 0$. We note that the L\"{u}scher-Weisz prescription yields an
excellent signal for the Wilson line with small error bars over almost 11
orders of magnitude.

We measure the ${\bf E}$ field for on axis separations (for definiteness
consider this to be in the $z$ direction) from the electric charge. Here we
need only measure $E_z$. For this we need to measure plaquettes in the $(z,t)$
plane containing the Wilson Line. We call the $z$ separation of the centre of
such a plaquette from the Wilson line $Z$. Clearly $Z$ takes the values
$\frac{1}{2},\frac{3}{2},\frac{5}{2},...,N_z-\frac{1}{2}$. It is also clear
that
\begin{eqnarray}
\langle E_z(Z)\rangle &=& -\langle E_z(N_z-Z)\rangle    \nonumber    \\
\langle D_z(Z)\rangle &=& -\langle D_z(N_z-Z)\rangle.
\end{eqnarray}
The lattice $D_z$ field is obtained by calculating
$\frac{\partial S}{\partial E_z}$, where $E_z$ is a $(z,t)$ plaquette and $S$
is the lattice action. The $\langle E_z \rangle_\rho$ and $\langle D_z
\rangle_\rho$ are obtained using equation~\ref{eqn:expect}. Again, the
L\"{u}scher-Weisz method yields a good signal. In what follows, we will drop
the subscripts $\rho$ and $z$ for convenience.

We will start by considering ${\bf D}$. Since the equation of motion
$\bm{\nabla \cdot D}=\rho$ holds for all $\beta$, this means that, to the
extent that we have rotational invariance, $\langle{\bf D}\rangle$ should be
independent of $\beta$, and equal to the classical value. Of course, since
we are on the lattice, rotational invariance is at best approximate, and we
expect departures from this expectation.

\label{fig:d0.0001}
\end{figure}

Figure~\ref{fig:d0.0001} shows the ratios of the ${\bf D}$ fields produced by
a point charge $e$ on both $8^4$ and $12^4$ lattices for $\beta=0.0001$, where
we expect the action to closely approximate the small $\beta$ limit of
equation~\ref{eqn:limit}, to their free field values. For the minimum
separation of source and field ($Z=\frac{1}{2}$) $D$ is consistent with its
free-field (Maxwell) value, evaluated on the same-size lattice. This is
because, at this separation, the discrete Gauss' equation plus cubic symmetry
is sufficient to uniquely determine $D$; in fact $D=\frac{1}{6}(1-1/{\cal
V})e$. At separation $Z=\frac{3}{2}$, $D$ has fallen to $86$--$87\%$ of its
free-field value. Gauss' law and cubic symmetry are no longer sufficient to
determine the $D$ field uniquely, and we do not have the simple relation
$\bm{D} = \bm{E}$ and hence $\nabla\times\bm{D}+\partial\bm{B}/\partial t=0$
of the Maxwell theory to help us. It is thus reassuring that ${\bf D}$ is as
close to its free-field value as it is. As the separation increases, the ratio
of $D$ to its free-field value appears to be approaching $1$. This is an
indication that rotational symmetry is restored at length scales much larger
than the lattice spacing. The fact that the ${\bf D}$ for this highly
non-linear theory appears identical to that of the Maxwell theory, apart from
lattice artifacts, is non-trivial. For the Maxwell theory, $\bm{D} = \bm{E}$,
while in the $\beta\rightarrow 0$ limit
$\bm{D}=\varepsilon(\bm{E\cdot B})\bm{B}$, where $\varepsilon$ is the familiar
sign function.

\end{figure}

Figure~\ref{fig:d1.0} shows the $e$ dependence of $D$, for $Z < N_z/2$, for
$\beta=1.0$. This $\beta$ is close to that which maximizes
$\langle S \rangle/V$. Thus, for this value of $\beta$, Born-Infeld QED should
be far from regular (Maxwell) QED, and also far from the non-linear limit of
equation~\ref{eqn:limit}. Again we see that at minimum separation, $D$ is
at its free field value. The ratio of $D$ to its free-field value falls to
a minimum for $1.5 \lesssim Z \lesssim 2.5$, after which it begins to increase
again. For the $8^4$ lattice, the finite lattice extent tends to suppress this
increase while the larger $12^4$ lattice shows a clear increase. Hence we see
evidence that rotational symmetry is being restored at large distances, just as
for small $\beta$. Again we believe that the difference between the $\beta=1.0$
${\bf D}$ fields and their free-field counterparts is a lattice artifact.

\label{fig:d100.0}
\end{figure}

In figure~\ref{fig:d100.0} we graph the ratios of $D$ to its free field value
for $\beta=100.0$, where we expect Born-Infeld QED to closely approximate
standard (Maxwell) QED. We note again that at minimum separation $D$ is
consistent with its free field value. At larger separations there are small
but significant departures from the Maxwell theory. However, since these
departures are always less than (and often considerably less than) one percent,
this is further evidence that $\beta=100.0$ Born-Infeld QED is close to
standard QED. Because these departures comparable in size with our error-bars,
it is difficult to make any more quantitative observations, although it does
appear that the $8^4$ and $12^4$ values are consistent for the ranges of $Z$
which they share.

We now turn our attention to the ${\bf E}$ field. Here, unlike the case of the
${\bf D}$ field, Maxwell's equations are of little help, because the relations
of equations~\ref{eqn:DH} are highly non-linear. What we are interested in
knowing is how similar these ${\bf E}$ fields are to their classical
counterparts and, in particular, whether they show the short-distance
screening of classical Born-Infeld electrodynamics. We shall use our
experience with the ${\bf D}$ fields as a guide to how much the results that
we observe are affected by lattice artifacts.

the on-axis separation $Z$: a) for an $8^4$ lattice, b) for a $12^4$ lattice.}
\label{fig:e0.0001}
\end{figure}

First we look at the case where $\beta=0.0001$ which we expect to be close
to the non-linear limit of equation~\ref{eqn:limit}. Figure~\ref{fig:e0.0001}
shows the ratios of $E$ to its free-field value for this $\beta$ as
functions of $e$ for all accessible values of $Z$. The similar graph (not shown)
for $\beta=0.01$ is almost identical, which justifies our claim that we are
close to the non-linear limit. We first note that the $8^4$ and $12^4$ graphs
are very similar for those $Z$ values common to each, indicating that we should
be able to extract information which is not dominated by finite volume effects
from lattices of this size. Secondly we notice that for all accessible $Z$s and
over most of the range of charges considered ($0 < e \le 3$), the electric
fields are larger than their free field counterparts by a factor of 2--3. This
contrasts with the classical case where $E \le D$. This enhancement of $E$ is
due to quantum fluctuations which are clearly quite large. At $Z=\frac{1}{2}$,
it is clear that ${\bf E}$ is screened, and that this screening increases with
increasing $e$. The $Z=\frac{3}{2}$ field also shows such screening, but the
falloff with increasing $e$ is much less pronounced than at $Z=\frac{1}{2}$,
while there is no clear signal for screening for larger $Z$. This behaviour is
qualitatively similar to what is observed classically. However, classically
its screening is determined by the ratio $e/b$ (or $r_0$), whereas in the
quantum theory, for small enough $b$ (and hence $\beta$) the screening becomes
$b$ independent. Since the limit $\beta \rightarrow 0$ can be achieved by
taking $a \rightarrow 0$ at fixed $b$, rather than $b \rightarrow 0$, the
non-linear limit of equation~\ref{eqn:limit} could be expected to describe the
continuum limit. The question arises as to whether this limiting field theory
is trivial or not. If it is trivial, the ${\bm E}$ field of a point charge (a
propagator of this field theory) would be proportional to the free field
propagator. Of course, this would only be true of this propagator at finite
distances in physical units, which as $a \rightarrow 0$ means large lattice
distances. Thus the fact that this ratio on the $12^4$ lattice varies by only
of order $5\%$ for $Z > 0.5$, at least for small charges, could be an
indication that this limit is trivial.

\begin{figure}[htb]

\label{fig:e1.0}
\end{figure}

Figure~\ref{fig:e1.0} shows $E/E_{free}$ as functions of $e$ for all accessible
separations $Z$, for $\beta=1.0$. Again, we note the similarity between the
results from the $8^4$ and $12^4$ lattices up until $Z$ approaches $N_z/2$
where the effect of the finite volume becomes apparent, which gives us
confidence that the finite volume effects are under control. Despite the fact
that we are now far from both the small and large $\beta$ limits, these graphs
are qualitatively similar to those for $\beta=0.0001$, except for the scale
on the vertical axis. The enhancement of this electric field over its Maxwell
value due to quantum fluctuations is smaller than that for $\beta=0.0001$.
The screening which we observe at $Z=\frac{1}{2}$ (and $Z=\frac{3}{2}$) is also
less by roughly a factor of 3 over the same range of charges $e$.

\begin{figure}[htb]

\label{fig:e100.0}
\end{figure}

In the last of this series of figures showing the $e$ and $Z$ dependence of
the ratio of $E$ to its free field value, figure~\ref{fig:e100.0}, we show
the results for $\beta=100$ where we expect Born-Infeld QED to be close to
its Maxwell (standard QED) limit. What is clear from these graphs is that,
since the $E$ never differs from its free field value by more than 2\% over the
range of $e$ considered, Born-Infeld QED is close to its free-field limit for
$\beta=100$. We do, however, observe a small increase in $E$ over its
free-field value due to quantum fluctuations, and see clear evidence for
weak screening for $Z=\frac{1}{2}$. This is good evidence that expanding the
square root in the action in powers of $1/\beta$, and using a perturbative
analysis, would be valid in this domain.

In an effort to get a more quantitative understanding of the screening of the
${\bf E}$ field that we have observed, we look again at the screening in
classical Born-Infeld electrodynamics. Here we can expose the screening length
($r_0$) by looking at
\begin{equation}
\left\{ {[\bm{E}(\bm{r})/e]_{e=0} \over [\bm{E}(\bm{r})/e]} \right\}^2
= 1 + \left({r \over r_0}\right)^4 = 1 + {1 \over 16\pi^2 b^2 r^4}\,e^2.
\end{equation}
So, for the classical case, plotting the left hand side of this equation for
fixed $r$ against $e^2$ (or $1/r_0^4$) would give a straight line.
Figure~\ref{fig:screening} shows this quantity from our simulations at
$\beta=0.0001$. While straight line fits to the $Z=\frac{1}{2}$ and
$Z=\frac{3}{2}$ are impossible, the straight lines we have drawn to guide the
eye indicate that the $e^2$ dependence is almost linear. Perhaps the observed
departures are due to lattice artifacts. What this behaviour does suggest is
that the screening increases without bound as $e^2$ is increased, as is true
classically.

b) on a $12^4$ lattice. Note that the straight lines drawn to aid the eye on
(a) and (b) are identical.}
\label{fig:screening}
\end{figure}

Finally, for completeness, we show the Wilson Line correlations for each of
the 16 charges for $\beta=100$ and $\beta=0.0001$
on the $12^4$ lattice in figure~\ref{fig:wilcor}.
These correlation functions show the interactions
between charge $+e$ and charge $-e$ separated by distance $Z$. What these
indicate is that the effect of screening on such interactions is to reduce
the correlation functions as $\beta$ is decreased (which as observed above,
increases screening). One expects that the Wilson Line correlation function
will behave as
\begin{equation}
\langle W(\bm{x})W^\dagger(\bm{x}+\bm{Z}) \rangle = C(Z)\exp[-V(Z)T].
\end{equation}
Although the electric field shows screening, $E$ for $\beta=0.0001$ exceeds
that for the free field and hence that for $\beta=100.0$ for the same charge,
over the range of charges considered. Hence, the potential energy $V(Z)$ at
$\beta=0.0001$ exceeds that for $\beta=100.0$. It is for this reason that this
correlation function falls more rapidly for the smaller $\beta$.

\section{Discussion and Conclusions}

Euclidean Born-Infeld electrodynamics has been quantized on a discrete
space-time lattice. The Euclidean action is positive, allowing us to simulate
this theory by importance sampling techniques. We have simulated the
gauge-invariant non-compact lattice implementation on $8^4$ and $12^4$ lattices
using standard Metropolis Monte-Carlo methods for several values of the
non-linearity parameter $b$ [or the dimensionless $\beta=b^2a^4$ ($a$ is the
lattice spacing)]. We measure the electric fields produced by a static point
charge $e$, as functions of that charge. On the lattice this charge is
introduced by the inclusion of a Wilson line (Polyakov loop). The phase of
this Wilson line introduces a sign problem. However, this sign problem is
overcome using the method of L\"{u}scher and Weisz, which uses partial
factorization of the functional integral to produce the exponential statistics
required to circumvent such sign problems. With this, we were able to obtain
excellent signals for the Wilson line, ${\bf E}$ and ${\bf D}$ fields, over
an appreciable range of $e$ values.

We performed simulations with $\beta$ values ranging from those large enough
to approximate the Maxwell (free-field) theory to the those where Born-Infeld
QED is well approximated by a $\beta$($b$)-independent conformal field theory
with Euclidean Lagrangian ${\cal L}_E = |\bm{E\cdot B}|$ or (in Minkowski
space) by the Hamiltonian ${\cal H} = |\bm{D} \times \bm{B}|$. For all $\beta$
values, the electric displacement ${\bf D}$ appears to differ from its value
in the Maxwell theory only by lattice artifacts. The electric field ${\bf E}$
shows considerable enhancement over its Maxwell value by as much as a factor of
$\approx 3$ due to quantum fluctuations. Away from the Maxwell limit, ${\bf E}$
exhibits short-distance screening with a screening length whose 4th power is
approximately linear in $e^2$, as in the classical theory. Also as in the
classical theory, screening is enhanced as $\beta$($b$) is increased. However,
unlike in the classical case where the screening at fixed $e$ increases
without limit as $b$ is increased, in the quantum theory this screening
approaches a limit described by the conformal field theory mentioned at the
beginning of this paragraph. Once this limit is achieved, the only way to
increase the screening length is to increase $|e|$.

Since our chief reason for studying Born-Infeld QED is because of its
connection to strings and branes, we only need to consider it as an effective
field theory with a momentum cutoff, or in our language, a finite lattice
spacing. However, it is interesting to consider whether one can remove the
momentum cutoff (take $a \rightarrow 0$) in such a way as to define a
renormalizable field theory. If we fix $b$ and take $a$ to zero, we are
taking the $\beta \rightarrow 0$ limit, where the field theory is described
by the Euclidean Lagrangian ${\cal L}_E = |\bm{E\cdot B}|$. Hence this theory
describes the infinite-momentum-cutoff limit of Born-Infeld QED. What we do
not know, is whether this quantum field theory is non-trivial. Our simulations
hint that the propagators of this theory might show free-field scaling.
However, the evidence is far from convincing, especially if we consider the
possibility that deviations from free-field scaling could well be logarithmic.

It would be useful to perform simulations of Born-Infeld QED on larger lattices,
possibly restricting these simulations to those using the action based on
the Lagrangian ${\cal L}_E = |\bm{E\cdot B}|$. Of more interest would be
simulations using those actions obtained from higher dimensional Born-Infeld
theories by dimensional reduction, which describe strings or branes with
transverse degrees of freedom. In these actions, the square root contains an
additional term $(\partial_\mu X_a)^2$, where the scalar fields $X_a$ are the
$n-p$ additional components of the $A$ field corresponding to the reduced
dimensions and are interpreted as the transverse displacements of the
$p$-brane. We plan such simulations in the near future.

The hanging gardens of Babylon were the inspiration for an architect's ambition to turn the city of Beirut into a "wonder forest".
Wassim Melki of StudioInvisible explained to Wired.co.uk that while the concept of rooftop gardens is far from new; he is proposing creating them "on a very large scale" throughout the city and its suburbs. And he is suggesting a simplified gardening approach to encourage the rooftop garden proliferation.
"Most conventional rooftop gardens are very complex," he explained. "They require a specific type of insulation and drainage, and a study should be conducted on the roof slab and how much weight it could support. Since many of the existing buildings are more than 50 years old, we are suggesting putting the trees in relatively large pots."
Melki adds that there is little if not no space in the city for creating new public green spaces, and "it's almost impossible to plant on the sidewalks or at the side of the roads". The solution is to take to the rooftops, argues the architect, and use the roofs of the 18,500 buildings in the city that are currently vacant. Says Melki: "If only one tree is planted on each, that's 18,500 more trees: which is the equivalent of Central Park in New York."
The StudioInvisible team is currently working on a plan, which will be presented to the Municipal powers-that-be as well as the Ministry of the Environment at the end of this month.

Widow to take on Great South Run in honour of husband who died two weeks after wedding
Sara and Paul Cranmer
Millie Salkeld
Published: 17:35 Saturday 20 October 2018
Promoted by Simplyhealth Great South Run
A WIDOW who lost her husband two weeks after their wedding is set to take part in the Great South Run tomorrow in his memory.
Sara Cranmer's husband Paul died from pancreatic cancer last August.
Sara Cranmer from Southsea in Portsmouth, was left widowed age 39 after her husband Paul died from pancreatic cancer last August. She is now running the SIMPLYHEALTH GREAT SOUTH RUN Iin his memory''Paul is on the left, taking part in 2008.
The pair met in 2015 and had plans to buy a house and start a family together but while holidaying in Goa, India last year he suddenly became jaundiced.
Sara, 39, from Southsea, said: 'He was diagnosed with pancreatic cancer. Our world fell apart.
Read more: Here's the full route for this year's Great South Run
'It was difficult for us both to comprehend and felt surreal at the time, like some terrible dream. How could this be happening to us?
Sara and Paul on their wedding day last August
'He had no symptoms until the jaundice, he felt well and we did not think for a moment that the cancer had an opportunity to spread and become untreatable.'
Paul, 45, was a huge Portsmouth FC fan who enjoyed playing football every week.
His diagnosis shocked his family.
Read more: Full list of road closures for the Great South Run
Sara said: 'It was such a shock because he was strong, fit and otherwise healthy man.'
Paul underwent a life-changing operation at Southampton General Hospital called The Whipple's Procedure and his loved ones were confident that this would be a success.
However, two months into Paul's recovery following the operation, they were then given the news that the cancer had spread and he was given between three and six months to live.
Sara, who is a student, said: 'One of the hardest decisions to make was whether to go ahead with chemotherapy to shrink the secondary tumour on his liver or not.
'Chemotherapy didn't seem worth the pain to us, we realised that his life quality would be pretty poor feeling weak and poorly from this treatment that could potentially extend his life by only a few months.
'So instead of being tied to hospital, we decided to live life for as long as possible.'
Paul and Sara wed in July last year and sadly just over two weeks later on August 8, Paul passed away.
Following the loss of her husband, Sara suffered with anxiety, post-traumatic stress disorder and depression but now she has decided she wants to take control and have a positive life focus, so she has signed up to run the 10 miles of the Simplyhealth Great South Run on Sunday, October 21 in her husband's memory – a race that Paul also ran in 10 years ago.
She will also raise money for Pancreatic Cancer UK.
Sara said: 'Paul's illness happened so quickly and unexpectedly it's taken a long time to process and comprehend.
'I still find it hard to believe that he was here one minute and suddenly gone the next.
'It's been the most challenging and difficult period of my life so far, but I've realised that I need to take control, look after myself and have a positive life focus.
'Paul would want me to make the most of every second of life as we know it can be cut short when you're least expecting it.'

Pancreatic metastases (PMs) account for 1% to 2% of pancreatic tumors, and their prognostic significance is poorly defined. We evaluated the incidence and clinical characteristics of primary tumors and defined prognostic factors. Methods This retrospective study of 39 Japanese tertiary referral hospitals (January 2005 to August 2015) analyzed patient and tumor characteristics and survival time. Kaplan-Meier analysis and Cox proportional hazards models were applied to evaluate overall survival and prognostic factors, respectively. Results We enrolled 159 patients with a pathologic diagnosis of PM. The most common primary tumor was renal cell carcinoma (38.4%), followed by lung cancer (24.5%), colorectal cancer (11.3%), and sarcoma (6.3%). Eight patients were lost during follow-up, and 151 patients were included for statistical analysis. Median overall survival was 43.0 months, and the 5-year survival rate was 42.6%. Multivariate analysis identified 3 independent prognostic factors: extrapancreatic metastasis (hazard ratio, 2.13; 95% confidence interval, 1.11-4.07; P = 0.02), tumor-related symptoms at diagnosis (hazard ratio, 5.39; 95% confidence interval, 2.92-9.91; P < 0.001), and pathologic diagnosis of primary tumors (P < 0.001). Conclusions Treatment strategies and prognoses for PMs completely differ according to the primary tumor type. A definitive pathologic diagnosis of PMs is essential for selecting the appropriate treatment.

N2 - Pancreatic metastases (PMs) account for 1% to 2% of pancreatic tumors, and their prognostic significance is poorly defined. We evaluated the incidence and clinical characteristics of primary tumors and defined prognostic factors. Methods This retrospective study of 39 Japanese tertiary referral hospitals (January 2005 to August 2015) analyzed patient and tumor characteristics and survival time. Kaplan-Meier analysis and Cox proportional hazards models were applied to evaluate overall survival and prognostic factors, respectively. Results We enrolled 159 patients with a pathologic diagnosis of PM. The most common primary tumor was renal cell carcinoma (38.4%), followed by lung cancer (24.5%), colorectal cancer (11.3%), and sarcoma (6.3%). Eight patients were lost during follow-up, and 151 patients were included for statistical analysis. Median overall survival was 43.0 months, and the 5-year survival rate was 42.6%. Multivariate analysis identified 3 independent prognostic factors: extrapancreatic metastasis (hazard ratio, 2.13; 95% confidence interval, 1.11-4.07; P = 0.02), tumor-related symptoms at diagnosis (hazard ratio, 5.39; 95% confidence interval, 2.92-9.91; P < 0.001), and pathologic diagnosis of primary tumors (P < 0.001). Conclusions Treatment strategies and prognoses for PMs completely differ according to the primary tumor type. A definitive pathologic diagnosis of PMs is essential for selecting the appropriate treatment.

Q: Django Models How To Upload Multiple Files For One Field I'm looking to upload multiple images from my front-end form (VueJS) to my 'photos' field. However, even with my foreign key, I can only link one image at a time. (I tried ArrayField too, but didn't work)
I know with Django forms.Form there's a widget option for 'attr multiple = True', but I can't seem to find a solution for models.
class Photos(models.Model):
    photos = models.ImageField(upload_to='uploads/',
                               null=True, default="")

class Actors(models.Model):

    user = models.ForeignKey(settings.AUTH_USER_MODEL,
                             on_delete=models.PROTECT, default="")
    Writing_Samples = models.FileField(upload_to='uploads/',
                                       null=True, default="no samples")
    photos = ForeignKey(
        Photos, on_delete=models.CASCADE, default="", null=True)

    gallery = ArrayField(
        models.CharField(max_length=100), blank=True, default="")

Thanks for your time!

A: To create multiple Photo instances for a single Actor instance, add the ForeignKey from the photo(s) to the actor.
class Actors(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, default="")
    Writing_Samples = models.FileField(upload_to='uploads/', null=True, default="no samples")

class Photos(models.Model):
    photo = models.ImageField(upload_to='uploads/', null=True, default="")
    actor = models.ForeignKey(Actors, on_delete=models.CASCADE, default="", null=True)
