Season Summary

The 1987 TFL Statewide League competition got underway on 4 April 1987 and was now a fully statewide concept with clubs from the South, North and North West participating.
There was much excitement on the North West Coast with Devonport undergoing a change of jumper, emblem and colours (formerly Magpies, now Blues) and coastal rival, Burnie Hawks (formerly Cooee) making their debut.

The standout performers this season were North Hobart, who swept all before them winning sixteen out of their eighteen roster matches and finished on top.
Glenorchy, Clarence and Hobart all performed very well throughout the season, all vying for top-two positions at various stages.
1986 Grand Finalists Sandy Bay, with the loss of as many as ten senior players from the previous year's team, performed poorly under Andy Bennett and slid to second last on the ladder by season's end.
Burnie Hawks, Devonport and the much-improved South Launceston all strived for the final spot in the top-five, Burnie Hawks managing to cling to fifth at the end of the roster series, six games (24 points) behind Hobart in fourth.
Devonport, whose history in the NWFU over the previous fifty years had been one of considerable under-achievement, having only won one flag since 1938 were looking in fine form midway through the season and were also challenging for a top-three spot, but fell in a heap at the latter end of the season dropping its final seven matches to miss the five by 10.70%, whilst South Launceston, who had performed very well at the latter end of the season needed to beat the rampaging North Hobart at Youngtown in the final round to make the finals but were demolished by 121-points.
New Norfolk, still sorting out their considerable financial problems stemming back to their 1982 TANFL Premiership year, weren't able to produce consistent football and remained in the bottom three.
North Launceston under coach Tony "Chang" Young struggled again to make an impact and finished on the bottom, however the club had earmarked some major changes to its playing list and coaching staff over the next eighteen months to become a power club once again.
Glenorchy and Clarence would again do battle in the finals, the Magpies winning a classic contest in the Qualifying Final after trailing for most of the first half, only winning in the closing minutes by 13-points.
The following day, Hobart and the Burnie Hawks met in the Elimination Final at KGV Football Park to an unusual sight in TFL Football, a thunderstorm just prior to the opening bounce.
The weather failed to dampen the Tigers spirits as they raced away after quarter-time to take a 51-point victory and earn a shot at Clarence in the First Semi Final.
The Second Semi Final between North Hobart and Glenorchy at North Hobart Oval was pretty much a one-sided contest after quarter-time as the Demons pegged back a slender Magpie lead and raced away with the match to win by 41-points, their followers were jubilant at the chance of seeing their Red & Blue heroes break a long premiership hoodoo.
At KGV Football Park the following day, Hobart and Clarence staged an epic First Semi Final.
The Roos held sway for much of the day including an 11-point three-quarter time lead, but Hobart struck back and 29-minutes into the final quarter, Hobart's Alistair Lynch marked 30-metres out from goal and was felled heavily by Clarence centre half-back Greg Farquahar (who was subsequently suspended for five matches over the incident), Lynch was stretchered from the ground.
Burly Tiger full-forward Wayne Fox took the kick to win the game for Hobart, but field umpire Haydyn Nielsen failed to pay the mandatory 15-metre penalty to Fox after reporting Farquahar, Fox's shot missed narrowly and the Roos were able to hold on for the final few seconds to win by four points.
Glenorchy and Clarence again met in the Preliminary Final at North Hobart Oval before an expectant crowd of almost 7,000 and the match did not disappoint.
The two bitterest rivals in Tasmanian football were neck and neck all day with many lead-changes but the Magpies held sway at all three changes, eventually holding out the Roos by twelve points to play in another Grand Final.
The Grand Final saw North Hobart hoping to end a premiership drought extending back to 1974, Glenorchy aiming for a hat-trick of TFL premierships.
The match was eerily similar to the Second Semi Final clash between the same two sides with Glenorchy getting out a fast start and North Hobart reeling them in and racing away with match.
North Hobart booted a Grand Final record 11.3 (69) in the second quarter to go into half-time 19-points to the good of the Magpies, then inflicting further damage in the third quarter by racing out a 56-point lead at the final change.
North Hobart fans celebrated wildly as their team broke its 13-year premiership drought in emphatic fashion by 52-points.
At North Hobart Oval, works commenced on the building of the $1.25 million Doug Plaister Stand, after the 1923-built Letitia Street Stand was destroyed by a mid-morning fire on Sunday, 31 May.
The stand, which had had works carried out on it in recent years by the Hobart City Council after ABC-Television engineers raised safety concerns over the structure in 1980 and had later been condemned in 1981, was destroyed when rubber matting was deliberately set on fire in a store-room at the rear of the structure, two youths were questioned by police over the fire but no charges were laid, the damage was estimated at $50,000 and the structure was demolished by the Hobart City Council that same day due to safety concerns.

Q: add text input on certain column table when clicked I'm quite new in jquery table . I have a code that will add text input in certain column that I clicked . In my case ,the column is number 9th .Below is my code :
$('#PtptnFileTblId_1').on( 'click', 'tbody td:not(:first-child)', function (e) {
        var id = $(this).attr('id');
        var file_id = $(this).attr('name');
        var code = $(this).text();

        var textrowId = $(this).children("td:nth-child(9)");
        textrowId.html("<input type='text' id='callerid' name='callerid' style='width:100px;' value=''/>");

A: In your event handler, $(this) refers to the cell that was clicked. You can use closest('TR') to retrieve the table row:
$('#PtptnFileTblId_1').on('click', 'tbody td:not(:first-child)', function (e) {
    ...
    var cell = $(this).closest('TR').children('td:nth-child(9)');
    cell.html("<input type='text' id='callerid' name='callerid' style='width:100px;' value='' />");
});

Ealing London Borough Council
Residents rewarded for recycling
ENVIRONMENTALLY friendly residents have won thousands of pounds for their areas for being the best recyclers in the borough.
recycle Image 1
The four prizes of £20,000 each have been handed out at the end of Ealing Council's Recycling Rewards scheme.
Elthorne and Hobbayne split the cash for being the best recyclers. They both reached 72.7 per cent of residents using the green boxes, food waste bins and bags for plastic and garden waste avoiding as much rubbish going to landfill as possible.
South Acton took £20,00 for the most improved ward with recycling rates jumping by 6.1 percent to 54.5 per cent.
Southfields and Northolt Mandeville wards also pick up £20,000 each for being the joint second most improved rising 4.1 per cent.
The money can be spent on improvements, such as hanging baskets, play equipment, murals and repairs to footpaths, and will be decided at the next ward forum meetings.
The wards were monitored from April to March, in which time an extra 370 tonnes of kerbside recycling was collected. This is the same as 370 classic Minis.
And 2608 less tonnes of waste was sent to landfill.
It meant the council paid £231,000 less landfill tax and was down to both an increase in recycling as well as a reduction in the amount households throw away overall.
Councillor Bassam Mahfouz, cabinet member for Transport and Environment, said: "A huge congratulations to all of the winning wards. This competition has shown it is possible to improve recycling rates and a special mention must go to South Acton, which improved by such a staggering amount.
"Thank you to everyone who took up recycling and helped reduce the amount of rubbish sent to landfill. The money saved can be spent on providing valuable services across the borough. I urge all residents to continue to recycle as much waste as possible."

Roke Develops World's First Miniature Self-Charging Tracking Device
Roke Manor Research Ltd
22 May, 2013, 08:00 BST
ROMSEY, England, May 22, 2013 /PRNewswire/ --
Roke Manor Research Ltd (Roke), a Chemring Group company, has developed AGITATE, a self-charging miniaturised device which generates a radio signal that can be tracked up to an estimated 200 kilometres away.
AGITATE is currently the size of a five pence piece. A small dielectric is charged, and when shaken the tag generates a radio signal that can be tracked through walls and up to 20 kilometres in built-up areas, with an estimated range of 200 kilometres in free space. AGITATE requires no battery as shaking it converts mechanical energy into radio pulses, rather like a dynamo that uses mechanical energy to power bicycle lights.
Roke's research and design team anticipate that AGITATE could be produced for a few pence per unit and would have a broad range of tracking applications. Potential uses might include a low cost method of monitoring and regulating the use of lifejackets, with built in man-overboard capability; remote sensing for flood monitoring and alerts; in the industrial sector for remote sensing of motion and vibration fault detection in harsh environments; in the retail sector as security tags on high-value goods or in the healthcare sector for keeping track of patients, such as those suffering from dementia.
The research and development team has already completed UK trials across 26 kilometres of variable terrain. Further Roke investment is focussed on reducing AGITATE's footprint and increasing RF output power even further.
Peter Lockhart, Future Technology Manager for Roke, said: "As with many of the best inventions, AGITATE was developed by accident. But thanks to their highly inventive and creative minds, they recognised a potential application and have brought that to fruition, developing a simple yet highly usable technology."

\section{Introduction}
Ultracold atoms trapped in periodic optical potentials provide wide-ranging opportunities to study many-body physics in highly controllable systems \cite{Maciej2007,Bloch2008}. In all cases, the characteristic single-particle energy scale is set by the recoil energy, $E_R = h^2 /(8md^2)$, where $m$ is the mass of the atom and $d$ is the spatial period of the lattice. Although temperatures in such systems can be quite low, it is still challenging to reach temperatures well below the relevant  many-body physics energy scales, which can be exceedingly small. Increasing the recoil energy can potentially increase both single-particle and many-body energy scales through tighter confinement, which may aid in creating systems well into the regime where many-body ground state physics is observable.  An inherent obstacle to smaller lattice spacing is the optical diffraction limit, which prevents lattice periodicities below $d = \lambda/2$, where $\lambda$ is the wavelength of the light forming the lattice.
Several approaches to move beyond the diffraction limit have been proposed and some realized based on multiphoton effects \cite{Dubetsky2002,Ritt2006,Anderson2019}, rf-dressed adiabatic potentials \cite{Yi2008,Lundblad2008,Lundblad2014}, and
trapping in near-field guided modes with nanophotonic
systems \cite{Gullans2012,Thompson2013,Romero-Isart2013,Gonzalez2015}.  \\

\caption{The stroboscopic approach to create a time-averaged effective potential with a lattice spacing of $\lambda/4$ by dynamically pulsing KP potentials with $\lambda/2$ spacing.}
\label{fig:schematic}
\end{figure}
Here we report the realization of a recently proposed Floquet-based approach~\cite{Nascimbene2015,Subhankar2019b,Lacki2019}  to create small-period lattices, specifically $\lambda/4$-spaced lattices, by time-averaging a modulated lattice potential that has subwavelength features. We load atoms into the ground band of this time-dependent lattice and measure their average probability density $|\psi_{\text{avg}}(x)|^2$ with nanoscale resolution \cite{Subhankar2019,McDonald2019,Tonyushkin2006}, to confirm the subwavelength nature of the lattice. We study the lifetime of atoms in the lattices over a range of modulation (Floquet) frequencies $\omega_F=2\pi/T$, where $T$ is the period of a complete cycle, to determine the frequency range over which the time-averaged approach works.

Creating an effective time-averaged potential requires that the time-dependence of the lattice be motionally diabatic \cite{Eckardt2017,Rahav2003,Marin2015}, namely that $T$ is much smaller than the motional time scale of the atoms.
Time-averaging a dynamically applied lattice potential cannot create an effective potential landscape with higher spatial Fourier components than the underlying progenitor lattice. This implies that in order to create landscapes with subwavelength periodicity, one must time-average a potential that itself has subwavelength features~\cite{Nascimbene2015}. In this work, we make use of the  Kronig-Penney(KP)-like potential to generate the desired potential landscapes~\cite{Subhankar2019b,Lacki2019}. Such a KP potential is implemented via the dark state associated with a three-level $\Lambda$-system \cite{Lacki2016,Jendrzejewski2016,Wang2018}. The spin adiabaticity required to maintain the dark state during the stroboscopic cycle imposes additional constraints, as discussed below.

\end{figure}

There are multiple ways to implement time-averaging with a KP lattice \cite{Lacki2019,Subhankar2019b}. The particular approach that we adopt, optimized for our experimental conditions, is shown in Fig.\ref{fig:schematic}. Periodic potentials with $\lambda/2$ spacing but subwavelength structure are stroboscopically applied to the atoms to create the desired potential landscape. Specifically,
atoms are subjected to a KP potential for half of the Floquet cycle $T/2$;
the potential is then ramped down to zero and its position is shifted by half of the lattice spacing $\lambda/4$;
the shifted potential is ramped on again and held for another half cycle, before being ramped off and its position is restored.

Two factors must be considered to ensure that time-averaging is an effective description of the system. First, motional diabaticity sets a lower bound on the Floquet frequency $\omega_F$, beyond which the band structure becomes unstable and severe heating limits the lifetime. Second, the dark-state nature of the KP lattice sets an upper bound to $\omega_F$. As the  KP potential is a scalar gauge potential arising from a spatially varying dark state~\cite{Wang2018,Lacki2016,Jendrzejewski2016}, switching on and off such a potential requires atoms to adiabatically follow the spatio-temporal dark state at all times. We ensure this adiabatic following by carefully designing the pulse shapes of our light fields (Appendix~C), implementing stimulated Raman adiabatic passage (STIRAP) \cite{Vitanov2017}. Losses occur at high $\omega_F$, as the atom's dark-state spin composition fails to adiabatically follow the rapid changes in the light fields. In the following sections, we show that a frequency window that simultaneously satisfies both requirements exists
 and that there are momentum-dependent loss channels arising from the Floquet-induced coupling with higher excited bands for particular momenta.
\section{Experiment}
We work with fermionic $^{171}$Yb atoms that have a well isolated $\Lambda$-system (Appendix~A), consisting of two ground states $|g_1\rangle$, $|g_2\rangle$
and an excited state $|e\rangle$ coupled by laser light with $\lambda=556$ nm. We use the methods outlined in Refs.~\cite{Wang2018,Vaidya2015,Pisenti2016, Subhankar2019c,Appel2009} to generate and optically control this well isolated $\Lambda$-system. A  control field  $\Omega_c(x,t)=\Omega_{c1}e^{ikx}+\Omega_{c2}(t)e^{-i(kx+\phi(t))}$, where $k=2\pi/\lambda$ and $\phi(t)$ is the relative phase difference between the two fields, which couples $|g_2\rangle$ and $|e\rangle$, is comprised of two counterpropagating lattice beams. The maximum value of $\Omega_{c2}(t)$ is constrained to be equal to $\Omega_{c1}=\Omega_{c0}/2$, in which case it gives rise to a standing wave $\Omega_{c0}\, e^{-i\phi(t)/2}\cos {(kx +\phi (t)/2)}$. We control the strength and the position of the KP potential using $\Omega_{c2}(t)$ and $\phi(t)$ (Appendix~C). A homogeneous probe field $\Omega_p e^{iky}$, coupling $|g_1\rangle$ and $|e\rangle$, travels perpendicular to the control beams. The resulting spatially dependent dark state gives rise to a KP lattice of narrow subwavlength barriers~\cite{Lacki2016,Jendrzejewski2016,Wang2018}, plus an additional sinusoidal potential due to the light shifts caused by states outside the three-level system (Appendix~A) as shown in Fig.~\ref{fig:wavefunction}(a).

Stroboscopically applying the lattice with different strengths and positions requires accurate and high bandwidth control of the amplitude and phase of the lasers coupling the three states, which we implement using dynamic control over the rf fields driving acousto-optic modulators (AOMs)~\cite{Subhankar2019}.  We note that the spin adiabaticity condition depends significantly on the pulse shape~\cite{Subhankar2019b} in addition to the Floquet frequency, and control of the pulse shape within a Floquet period is critical~\cite{Subhankar2019}. We use arbitrary waveform generators that can control the rf amplitude and phase with a resolution of 8 ns and 4 ns respectively. However, we are limited by the bandwidth of the AOMs, which we measure to be 50 ns. This is a factor of 8 times smaller than the smallest half-period of 400 ns that we have used in this study.

For typical experimental values of $\Omega_{c0}=500$~$\Gamma$ and $\Omega_p=50$~$\Gamma$, where $\Gamma=2\pi\times182$~kHz is the inverse lifetime of $|e\rangle$, the KP barrier has a minimum width of 0.02~$\lambda$ and a maximum height $\approx 100 E_R$, where $E_R/h=h/(2m_{\text{Yb}} \lambda^2)=3.7$~kHz, $m_{\text{Yb}}$ is the mass of a $^{171}$Yb atom, and the sinusoidal potential has a depth $\approx 145 E_R$, Fig.~\ref{fig:wavefunction}(a). Time-averaging this lattice applied at two positions results in an effective potential $V_{\text{eff}}(x)$ shown in Fig.~\ref{fig:wavefunction}(b), which includes the effect of the pulse shapes, with an effective barrier height $\approx7 E_R$. (The sinusoidal component of the potential averages to a spatially invariant offset.)

\section{Measurement}
We apply this lattice to $\approx 2\times10^5$ Yb atoms at an initial temperature of 0.3 $\mu$K that have been optically pumped into $|g_1\rangle$.
To load the atoms into the ground band of $V_{\text{eff}}(x)$, we adiabatically increase the depth of the stroboscopically applied lattices in 200 $\mu s$ (typically $\sim$80 Floquet cycles) described in details in Appendix~B. After the loading stage, we  measure the ensemble-averaged probability density $|\psi(x,t)|^2$ of atoms in the ground band of $V_{\text{eff}}(x)$ using a nanoresolution miscroscopy technique~\cite{Subhankar2019} with FWHM resolution of 25~nm. We also measure the momentum distribution of the atoms via absorption imaging after time-of-flight (TOF).

\subsection{Probing wavefunction density in the stroboscopic lattice}
Figure \ref{fig:wavefunction}(c) shows $|\psi(x,t)|^2$ averaged over a Floquet period $T=2.4\,\mu s$ ($\omega_F=2\pi \times 410$ kHz) for atoms in $V_{\text{eff}}(x)$ with a $\lambda/4 $ lattice spacing, and Fig.~\ref{fig:wavefunction}(d) shows $|\psi(x,t)|^2$ at different times within a Floquet cycle. By averaging the data over a Floquet period, we eliminate the effect of micromotion and obtain the averaged wavefunction density $|\psi_{\text{avg}}(x)|^2$ (dotted trace in Fig.\ref{fig:wavefunction}(c)) in the ground band of the effective potential. The black curve represents the ground-band probability density calculated from the time-averaged potential including the quasimomentum averaging, the effect of finite resolution of the microscope, and the relaxation of the wavefunction during the measurement. The good agreement between the data and calculation shows that time-averaging is a good description of the effective potential. The calculated wavefunction in the lattice before the relaxation during the measurement is plotted in grey. We resolve the micromotion in real space within a Floquet period by comparing $|\psi(x,t)|^2$ with $|\psi_{\text{avg}}(x)|^2$ (Fig.\ref{fig:wavefunction}(d)). The blue (red)-shaded areas represents regions in which $|\psi(x,t)|^2$ is higher (lower) than $|\psi_{\text{avg}}(x)|^2$. We observe that micromotion has the same time-periodicity as the Floquet drive, as expected.

(b) The Floquet frequency $\omega_F$ is plotted versus the center momentum of the populations in (a) determined using Gaussian fits. Different series of avoided crossing are labeled and colored (L1: green, L2: red, R1: blue) and their fitted quadratic functions are drawn in solid lines respectively. The error bars are 1 standard deviation of the Gaussian fits. }
\end{figure}
\subsection{Momentum-dependent loss channels}
A characteristic feature of a Bloch-Floquet bandstructure is the existence of avoided crossings at particular lattice momenta arising from coupling with high-lying states \cite{Holthaus_2015}, which for large Floquet frequency are approximately plane waves with high momenta. We measure the momentum distribution of the atoms in $V_{\text{eff}}(x)$ at different $\omega_F$ by taking an absorption image after ramping down the lattice in 100 $\mu s$ followed by a TOF of 3~ms. The atomic populations at high momenta in Fig.\ref{fig:TOF}(a) indicate the mixing of low momentum and high momentum states due to the presence of avoided crossings in our system. We use a Gaussian fit to determine the center momentum of the populations with respect to the ground band. The Floquet frequency $\omega_F$ is plotted against the center momentum (Fig.\ref{fig:TOF}(b)) for the three most prominent peaks (L1: green, L2: red, R1: blue).  To first order, the avoided crossings can be understood as arising from the crossing of Floquet dressed high-lying bands, which are shifted in energy by integral multiples of $\omega_F$, and the low-lying occupied bands of $V_{\text{eff}}(x)$, which are relatively flat. To determine the integral multiple of $\omega_F$ for the band coupling, we fit the peak positions with a quadratic function $\hbar \omega_F=(p-p_0)^2/N +\hbar \omega_0$, where $p$ is the momentum, $N$ is an integer, $p_0$ and $\omega_0$ are fitting parameters, and the momentum and energy are in units of $\hbar k$ and $E_R$. For the L1 series, a good agreement with the data is found for $N=1$, indicating this series is due to coupling between bands with an energy difference of $\hbar\omega_F$. For the L2 and R1 series, $N=2$ gives the best fit, indicating second order coupling between bands that differ in energy by 2$\hbar\omega_F$. (The other visible peaks do not extend over a sufficient range to accurately determine their curvatures.)  The fraction of atoms in the high momentum states decreases at higher Floquet frequency, suggesting weaker coupling to higher bands. The asymmetry in the avoided crossings with respect to $p=0$ is due to the fact that we are driving just the $\Omega_{c2}$ control beam, which gives rise to a vector gauge potential~\cite{Subhankar2019b}.

The $^{171}$Yb atoms are nearly non-interacting ($s$-wave scattering length is $-3a_0$, where $a_0$ is the Bohr radius), so they are not likely to thermalize during the short loading and unloading sequence.  However, the observed low-momentum component of the TOF distribution is consistent with the width of the ground band Brillouin zone for the $\lambda/4$-spaced stroboscopic lattice, which is twice as large as the ground band width of the progenitor $\lambda/2$ lattice. Given that the Fermi momentum at our density is of order the recoil momentum of the progenitor lattice, the filled ground band in the $\lambda/4$ lattice indicates that the effective temperature is higher than the ground band width but not a significant fraction of the band spacing.

\end{figure}

\subsection{Lifetime study}
In order to determine the range of usable Floquet frequencies for the stroboscopic scheme, we study the lifetime at different $\omega_F$ under different Rabi frequency configurations as shown in Fig.~\ref{fig:lifetime}. We determine the lower bound on $\omega_F$ by studying the motional diabaticity of atoms in just a stroboscopically applied ac-Stark-shift lattice. This is done by setting $\Omega_p=0$, which decouples the spin degree of freedom from the dynamics with $\Omega_{c1}=250\Gamma$, while $\Omega_{c2}(t)$ is pulsed to a maximum value of $250\Gamma$(Appendix~C). At low $\omega_F$, the atoms are affected by the turning on and off, and phase shifting of the sinusoidal ac-Stark-shift potential, which causes heating and loss (green squares in Fig.\ref{fig:lifetime}). We determine the upper bound on $\omega_F$ by studying the reduction in the fidelity of STIRAP as a function of $\omega_F$ for a spatially homogeneous dark state. This is done by setting $\Omega_{c1}=0$, $\Omega_p=80\Gamma$, while $\Omega_{c2}(t)$ is pulsed to a maximum value of $250\Gamma$. The reduction in STIRAP fidelity manifests as heating and loss due to the decreasing spin adiabaticity at larger $\omega_F$. Most importantly, we also measure the frequency dependent lifetime of atoms loaded into $V_{\text{eff}}(x)$ for different $\omega_F$ (blue circles in Fig.\ref{fig:lifetime}). The reduction in spin adiabaticity accounts for the decrease in lifetime of atoms in $V_{\text{eff}}(x)$ at high $\omega_F$.

The short lifetimes in the stroboscopically applied KP lattices are expected due to a few factors. First, couplings to the spatially and temporally dependent bright states reduce lifetimes in subwavelength-spaced lattices even for a perfect three-level system, through couplings with higher Floquet bands (as shown in Fig.~\ref{fig:TOF}) and off-resonant couplings with bright states~\cite{Subhankar2019b}. In principle, these couplings can be reduced by using larger Rabi frequencies. However, lifetimes are also limited by the breakdown of the three-level approximation at large Rabi frequencies due to admixing of states outside the three-level system (Appendix~A). This manifests as a dynamically varying and spatially dependent two-photon detuning (arising from $\Omega_c(x,t)$), which reduces the fidelity of STIRAP~\cite{Vitanov2017}. This competing requirement prevents us from benefiting from larger Rabi frequencies.

\section{Conclusion}
In conclusion, we demonstrate the creation of a time-averaged $\lambda/4$-spaced lattice using a recently proposed stroboscopic technique~\cite{Nascimbene2015} based on dynamically modulated dark states in a three-level system~\cite{Subhankar2019b,Lacki2019}. The subwavelength structure of the lattice is confirmed by measuring the probability density of the atoms averaged over the ground band of the lattice.  We measure the loss rate of atoms in the lattice and observe high momentum excitation due to Floquet-induced coupling to higher bands. We measure the lifetime of the atoms in the $\lambda/4$-spaced lattice to be 2~ms,  which is not long enough compared to the tunneling time to allow for many-body studies in the current realization.

Further improvement of the $\lambda/4$-spaced lattice would require compensation of the two-photon detuning\st{s} or the identification of other atomic systems with a more favorable (isolated) three-level system~\cite{Bienias2018}.
The lattice demonstrated here is limited by the off-resonant coupling to $|(6s6p)^3P_1,F$=$3/2,m_F$=$-3/2\rangle$, which is only detuned by the hyperfine splitting from the three-level system being used. Better candidates may make use of isolated {\em electronic} levels, which are detuned by much larger optical separations.
For example, in $^{174}$Yb, the $(6s6p)^3P_0$ state and one of the states in the $(6s6p)^3P_2$ level could be used as the ground states, while one of the $(6s7s)^3S_1$ states could be used as the excited state, with appropriate choice of polarization to select the three states. In a more isolated three-level system the main limitation would be the available laser power needed to meet the Rabi frequency requirements. In addition to longer lifetimes, higher Rabi frequencies would allow for lattices with smaller spacings~\cite{Subhankar2019b}. Our work can be extended to 2D and additional dynamic control over the two-photon detuning---which makes subwavelength traps possible~\cite{Bienias2018}---allows for construction of arbitrary time-averaged potential landscapes not limited by diffraction.

\end{figure*}
Fig. 5 shows the level structure of the $^1S_0$ and $^3P_1$ manifolds in $^{171}\text{Yb}$. The three hyperfine states $|g_1\rangle$, $|g_2\rangle$, and $|e\rangle$ constitute the $\Lambda$-system. We use a magnetic field of 36~mT to yield a frequency separation of 1 GHz between $|e\rangle$ and $|4\rangle$. The hyperfine splitting is $\Delta_{\text{HFS}}\approx6$~GHz.

The ac-Stark shifts on the ground states $|g_1\rangle$ and $|g_2\rangle$ arise due to off-resonant couplings to states outside the $\Lambda$-system. The $\Omega_c(x,t)$ light field off-resonantly couples $|g_1\rangle$ with $|5\rangle$, and $|g_2\rangle$ with $|6\rangle$. The $\Omega_p$ light field off-resonantly couples $|g_2\rangle$ with $|4\rangle$, $|g_2\rangle$ with $|7\rangle$, and $|g_1\rangle$ with $|6\rangle$. The spatio-temporally dependent ac-Stark shifts due to $\Omega_c(x,t)$ give rise to the dynamic sinusoidal potential mentioned in the main text.
\subsection{EXPERIMENTAL SEQUENCE}
\label{ExperimentalSequence}
Fig. 6 shows the experimental sequence that we use to load atoms into the ground band of the stroboscopic lattice.

\begin{enumerate}[label=\Roman*.]
	\item We start with atoms optically pumped into $|g_1\rangle$. We then ramp on $\Omega_{c1}$ (red trace in Fig.6) followed by $\Omega_p$ (blue trace in Fig.6), transferring atoms into a spatially homogeneous dark state. Then, we turn on $\Omega_{c2}(t)$ (green trace in Fig.6) in 200$\mu$s (minimum number of Floquet cycles used during the ramp $\approx$ 40) to adiabatically load atoms into the ground band of the stroboscopic lattice.
	\item We pulse the stroboscopic lattice for a variable number of Floquet cycles.

	\item We measure the average probability density of the atoms in the ground band of the stroboscopic lattice using the nanoresolution microscopy technique described in Ref.~\cite{Subhankar2019}.
\end{enumerate}
The phase $\phi(t)$ of the $\Omega_{c2}$ light field, which controls the position of the stroboscopic lattice, is only changed when the dark-state spin composition is spatially homogeneous~\cite{Subhankar2019b}. The experimental techniques used to generate the pulses is detailed in Ref.~\cite{Subhankar2019}.
\subsection{PULSE SCHEME}
\label{PulseScheme}

The functional form of $\Omega_{c2}(t)$ that we use to create the stroboscopic lattice is~\cite{Subhankar2019b}:
$$
\Omega_{c2}(t)=\frac{\Omega_{c0}}{2}-\frac{\Omega_{p}\sin^2(\omega_F t)}{\sqrt{1+4\epsilon^2-\sin^4(\omega_F t)}},$$
$$
\omega_F=\Omega_pr_0\sqrt{1+4\epsilon^2},
$$
where $\epsilon=\Omega_p/\Omega_{c0}$. In Fig.~4 , changes in $\omega_F$ are parameterized using $r_0.$ Smaller $r_0$ implies slower, more spin-adiabatic pulses. In our experiment, we typically use $0.02\le r_0\le0.2$. One Floquet period of pulsing is shown in Fig.~7.

	\caption{One Floquet cycle of pulsing: The pulse shapes for $\Omega_{c2}(t)$ and $\phi(t)$. }
\end{figure}
\subsection{DETAIL OF LIFETIME STUDY}
\label{DetailofLifetimeStudy}
When studying lifetime for the STIRAP-only case and for the stroboscopic lattice case, we observe that $\sim20\%$ of the atoms have a lifetime of $\sim$ 20 ms and are insensitive to change in $\omega_F$. We speculate that these atoms populate Floquet states that are immune to STIRAP due to the large dynamic two-photon detunings arising from the spatially-dependent ac-Stark shifts due to couplings to states outside the $\Lambda$-system (Appendix~A). The decay rates shown in the main text pertain to the major fraction of the atoms which show frequency-dependent loss rates both in the stroboscopic lattice as well as stroboscopic STIRAP case.

Over the past five years solar photovoltaic (PV) power supply systems have matured and are now being deployed on a much larger scale. The traditional small-scale remote area power supply systems are still important and village electrification is also a large and growing market but large scale, grid-connected systems and building integrated systems are now being deployed in many countries. This growth has been aided by imaginative government policies in several countries and the overall result is a growth rate of over 40% per annum in the sales of PV systems. Optimistic forecasts are being made about the future of PV power as a major source of sustainable energy. Plans are now being formulated by the IEA for very large-scale PV installations of more than 100 MW peak output. The Australian Government has announced a subsidy for a large solar photovoltaic power station of 154 MW in Victoria, based on the concentrator technology developed in Australia. In Western Australia a proposal has been submitted to the State Government for a 2 MW photovoltaic power system to provide fringe of grid support at Perenjori. This paper outlines the technologies, designs, management and policies that underpin these exciting developments in solar PV power.

Justice Umar Ata Bandial to take oath as Chief Justice on Feb 2
1 week ago Newsdesk
ISLAMABAD: Supreme Court Justice Umar Ata Bandial will take oath as Pakistan's 28th chief justice on February 2, replacing incumbent CJP Justice Gulzar Ahmed, Geo News reported Wednesday.
The change will take place on the principle of seniority in which the puisne judge becomes the chief justice.
The Ministry of Law and Justice secretary has sent the summary to President Arif Alvi to appoint Justice Bandial as the next CJP.
After the president's nod, the ministry will issue a notification.
Justice Bandial will continue as the chief justice till his retirement on September 18, 2023, and will hold the position for some 19 months.
Supreme Court judges, including the chief justice, retire once they are 65, while high court justices superannuate on reaching 62 years of age under the constitution.
CJP Gulzar Ahmed will retire after working in the top judicial position for more than two years. Justice Ahmed assumed office on December 21, 2019, replacing ex-CJP Justice Saqib Nisar.
Justice Bandial had declined oath under PCO [provisional constitutional order of Pervez Musharraf] in November 2007 but was restored as an LHC judge as a result of the lawyers' movement for the revival of the judiciary and constitutional rule in the country.
Later, he served for two years as the LHC chief justice until his elevation as a judge of the Supreme Court in June 2014.
Chief Justice Shaikh again declines to be ad hoc judge
During his career as a judge of the LHC and the Supreme Court, he has rendered judgments on a number of important public law and private law issues.
Future scenario at Apex court
Following Justice Bandial's superannuation, Justice Qazi Faez Isa will become the chief justice to serve this office for over one year till October 25, 2024.
In between, Justice Maqbool Baqar will retire without becoming the chief justice. Similarly, Justice Mazhar Alam Khan will also superannuate without being the chief justice.
However, after the superannuation of Justice Qazi Faez Isa, Justice Ijazul Ahsan will become the chief justice and work in this position for some 10 months till August 4, 2025.
Article 175A says the president will appoint the most senior judge of the Supreme Court as the chief justice.
Qazi Faiz Issa will become Chief Justice Insha Allah, says Maryam Nawaz

Instagram is testing a way to tag your friends in videos
By James Peckham published 11 September 18
It may come to you soon
Ever been frustrated with Instagram when it doesn't let you tag your friends in video clips? The social network may be about to change that as it's currently testing a way to link your friends accounts to the videos you post.
Instagram photo tags provide little icons to show who is in the image when you press down, but that isn't how the new test is working for video. Instead it takes you to a separate page with a listing of everyone tagged in the video.
That will make it difficult to identify individual people in the video, but it negates the problem of people moving around in the clip and being tagged incorrectly.
According to TechCrunch, the test is underway with a very small number of Instagram users. If it is deemed a success, we may soon see the feature roll out to all users, but there will likely be a few changes.
Who is that?
At the moment, if you're tagged from an account testing the feature it won't appear on your profile. We expect this will be something that's changed for the final release. It's also just for mobile devices at the moment, so you can't tag videos when using the web version of Instagram.
Considering Instagram's prowess in the world of augmented reality filters on Instagram Stories video we'd love to see the company come up with a system that tracks people for tagging rather than taking you to a separate page.
That's not going to happen soon though, so for now we'll have to be happy with this new tagging feature.
Whether we'll see this new feature roll out soon depends on how well Instagram believes the test has gone, but it feels like a feature we've been missing on the social network for some time.

Surrounded by farmland and ranches, Colorado's Edison School sits off an unpaved road, with tumbleweeds blowing across its dirt parking lot. As recently as a few years ago, many families relied on solar or wind power instead of electricity; today, many still haul home their water from wells. Principal Rachel Paul estimates that 25 to 30 percent of her students don't have Internet access at home.
Yet at Edison — where about three-quarters of the 120 K-12 students are eligible for free or reduced-priced lunch — there are as many computers as there are students. On one recent day, Paul Frank's fourth- and fifth-graders started off by learning about latitude and longitude on Google Maps and ended sprawled around the classroom on laptops, putting together presentations about the Midwest. While one student searched for photos of famous people born in Minnesota and Wisconsin, another used Google to find out Nebraska's annual rainfall.
Frank and administrators in the two-school district, located an hour east of Colorado Springs in Yoder, Colo., have big technological ambitions. They want to infuse technology into every bit of the curriculum, from using iPods to help elementary students practice reading to mandating that high-school seniors take a computer-science course to graduate.
It's not about improving test scores — last year, every single one of Edison's elementary students was deemed proficient on the state's math exam. Instead, the goal is to expand the students' horizons and prepare them for college and the workplace, where technological literacy will be assumed.
Rural schools have long been leaders in distance-learning and online education — to offer a full slate of courses to their students, they've had to be. In fact, Edison has a fully online school that enrolls about 100 other students in the district. But when it comes to technology inside traditional classrooms, the small sizes — and budgets — of rural schools present unique hurdles.
Some states, fearing a divide between rural and urban communities, have developed statewide initiatives to provide technology to rural schools. Maine, for instance, gives every student a laptop, and Alabama requires all school districts to offer Advanced Placement courses through distance-learning technology, where students video-conference with teachers.
But in many places, the onus is on the already-strained staff of the schools to acquire and then use things like computers and iPads, leading to pockets of innovation, like that in Edison. Although it leaves a line in its budget for technology upkeep, Edison has supplemented its tech experimentation with a $10,000 grant from the Denver-based Morgridge Family Foundation.
Rural America lags behind the rest of the country in Internet usage, making rural schools an important center of connectivity in the communities. In 2010, for instance, 57 percent of rural households had broadband Internet access, compared to 72 percent in urban areas, according to a November 2011 report by the U.S. Department of Commerce.
In Yoder, Frank tries an experiment with his students every few months. He gives them a homework assignment that must be submitted by email. When he started doing this a few years ago, he'd be lucky to get five responses. Most recently, all but three of his 21 students emailed him something. In part, he said, the improvement is a result of work the phone company has done in the area, making it easier for homes to get broadband Internet access.
While technology doesn't necessarily lead to better student performance, it can expand students' horizons beyond just preparing them for college or the workforce.
Edison has used distance-learning equipment to take elementary students on a field trip to NASA and to teach them about the Civil War. Frank's classroom frequently practices writing and communication skills by "blogging" on class discussion boards about stories they've read. High-school students might use Rosetta Stone to learn Spanish or watch free videos from the Khan Academy to master math concepts. Before receiving their diplomas, all students learn the basic coding behind computer games.
Howley has found that rural teachers are open to using technology in their classrooms, but she cautioned that doing so in rural schools typically requires innovative faculty to take on extra responsibilities. Even then, schools often don't have the money to buy computers or tablets and offer teachers corresponding training.
Teachers not only need to know how to use new gadgets, but also must be prepared to use the tools in ways that improve student learning, Howley said. Although Edison's grant money has paid for some teacher training, it's not enough to cover everything.
Frank, the self-proclaimed technology "guinea pig," has learned by doing. When he first got an interactive Smartboard, for instance, he and his students learned together how do to things like upload textbooks and record attendance. Now, he's got the other elementary teachers using Smartboards and even iPod Touches to monitor reading fluency, but the laptops rarely leave his classroom.
Edison joins with other schools in the area to share an IT person, who comes once a week and mainly tends to the school's servers. Without extra help, though, Edison may have reached its limits. "At this point, getting more technology would be a disaster," Binkley-Jones said.
Although many staff members say students are enthusiastic and take to technology easily, Binkley-Jones finds herself teaching basic computer skills — how to open or save Word documents, for example — to high-school students.
As the school moves forward with its five-year technology plan, which will include expanding distance-learning and more training for teachers, the elementary staff will need to address that.
This story, "Bridging the digital divide in America's rural schools," was produced by The Hechinger Report, a nonprofit, nonpartisan education-news outlet based at Teachers College, Columbia University.


Unlike FOX's brilliant Arrested Development, Eulogy's spectacle of nastiness doesn't indicate a family's greater, largely unspoken love for one another. Even when they're kind to each other, the Bluth family from Ron Howard's exec produced sitcom still refuses to play nice. The Bluth children are slaves to their dysfunctional upbringing, but love is clearly coded into their sarcasm. In essence: Their love is consistent with their hate. This complexity of emotion and behavior isn't evidenced throughout Michael Clancy's Eulogy, which betrays itself by resorting to cheap sentiment by film's end. Sitting across the table from an about-to-be-distressed older woman, Kate Collins (Zooey Deschanel) promises to tell a doozy of a story. "All of my life my grandfather said never to pick up the phone on the first ring…and now he was dead," begins the young woman before describing the days leading up to her grandfather's funeral when her immediate family comes together at her grandmother's home. In the tradition of monstrosities like Home for the Holidays and Greedy, Eulogy confuses mean-spiritedness for signs of intelligent life. George S. Clinton's schmaltzy score is scarcely subversive, and as such belies the film's nasty streak. Gathered around the dinner table, Mom (Piper Laurie) forces her favorite son (Hank Azaria) to speak the one-liner from his famous peanut butter commercial. When the hip dyke played by Kelly Preston announces her plans to marry her lover (Famke Janssen), her sister (Debra Winger) kills the mood with anti-gay nastiness. Everything is played for laughs, and some of it might actually be funny if it didn't sound so outmoded. Some of the film's random bits are amusing (Azaria's evil twins attempt to move food products across a kitchen using only their eyes and feet), but most of the gags are less left-of-center than just plain square. Indeed, I demand an instant moratorium on films featuring moms and dads rolling doobies.

Il rift del Golfo di Suez è una zona di rift continentale che fu attiva tra il tardo Oligocene (circa 28 milioni di anni fa) e la fine del Miocene (circa 5 milioni di anni fa).

Rappresentava una continuazione del rift del Mar Rosso fino alla separazione avvenuta a metà del Miocene, quando gran parte dello spostamento sul neo formatosi centro di divergenza del Mar Rosso andò a finire nella faglia trasforme del Mar Morto. Durante la breve storia successiva alla formazione del rift, la parte più profonda della topografia residua del rift è stata riempita dal mare, creando così il Golfo di Suez.

A nord del Golfo di Suez, il rift diventa indistinto e la sua esatta geometria diviene incerta, collegandosi alla fine al rift di Manzala, al di sotto del delta del Nilo.

Situazione tettonica
La formazione del sistema di rift Mar Rosso-Golfo di Suez fu causata da una rotazione antioraria della placca araba rispetto alla placca africana. Questo modello è in accordo con il rifting quasi ortogonale lungo l'intera lunghezza del sistema di rift. I modelli alternativi che suggeriscono un inizio innescato dallo sviluppo di una faglia trasforme o di un bacino distensivo lungo lungo l'asse del rift, non sono stati supportati da studi dettagliati della geometri del rift.

Verso la fine del Miocene, la placca araba iniziò a collidere con la placca euroasiatica portando a cambiamenti della configurazione della placca, allo sviluppo della faglia trasforme del Mar Morto e alla cessazione dell'attività di rifting nel golfo di Suez.

Basamento cristallino
Il basamento cristallino consiste di rocce dello scudo arabo-nubiano risalenti al Precambriano.

Gneiss, rocce vulcaniche e metasedimenti sono intrusi da granito, granodiorite e una serie di dicchi di dolerite. Le rocce contengono zone di taglio, come nella cesura di Rehba ad ovest del Sinai, che si ritiene abbiano parzialmente controllato l'orientazione e la localizzazione delle strutture del rift.

Evoluzione storica

Situazione precedente al rifting
Tra la fine del Cretacico e l'Eocene, nell'area attualmente occupa dal rift era presente un mare poco profondo dove si depositavano carbonati. Il periodo era tettonicamente stabile, ma nella parte settentrionale della regione del golfo si facevano periodicamente sentire gli effetti della lontana orogenesi alpina. Una serie di bacini con estensioni strutturali in direzione WSW-ENE si invertirono, creando sollevamenti isolati e aree di piegature note come strutture dell'arco siriano. Queste strutture erano attive principalmente durante il tardo Santoniano, ma ci sono evidenze di ulteriori movimenti sulle stesse strutture alla fine del Cretacico e durante il Paleogene.

Rifting
La formazione del rift iniziò in tutto il sistema di rift del Mar Rosso-Golfo di Suez durante il tardo Oligocene. Nel Golfo di Suez, il rifting raggiunse il culmine durante il Burdigaliano, circa 18 milioni di anni fa, all'inizio del Miocene.

Verso la metà del Miocene avvenne la fratturazione lungo l'intera lunghezza del rift, accompagnata dall'inizio dell'espansione del fondale oceanico nel tardo Miocene. La fratturazione fu associata a una graduale riduzione della velocità di rifting lungo il Golfo di Suez, con l'arresto della maggior parte dell'attività all'inizio del Pliocene.

Situazione post-rift
Dalla fine del Miocene, nell'area del rift del Golfo di Suez è iniziato un processo di subsidenza termica accompagnata dall'allagamento delle aree topograficamente più basse della regione.

Tiffany Shlain of Mill Valley
by Mimi Towle October 11, 2010
Photo by Tim Porter
Tiffany Shlain became Wikipedia-worthy (and very busy) back in 1996, at the ripe age of 26, as the founder of the Webby Awards. Today Shlain juggles motherhood (seven-year-old Odessa and almost-two-year-old Electra) and her filmmaking career, praising the Internet for allowing her to work from home sometimes and motherhood for reminding her of the importance of tickling, baking and butterfly spotting. Having grown up in Mill Valley (a Mill Valley Middle School Panther!), she and her family moved back to town from San Francisco in 2006 in search of redwoods and simplicity.
Favorite memories of growing up in Marin? There was this magical, funky place across from Mill Valley Market in the '70's called the Unknown Museum. As a child it was like walking into a Terry Gilliam film…there were art cars covered with Barbie dolls, mirrors and things like Atari handsets. There was also a life-size horse completely covered with plastic objects from our collective experience. Other memories include rafting down Miller Avenue during the floods, my mom's jean jumpsuit covered with sports car patches as she cheered us on at baseball games at Boyle Park and then the geodesic dome my dad built in our backyard complete with a hot tub.
Your June 2010 commencement speech at UC Berkeley went viral; was this expected? I was so honored to be asked to give this address. It was a pivotal moment for me. I had just lost my father (Leonard Shlain), turned 40 and had a new baby. It pushed me to articulate where I was in life, what I had learned so far, and then present this to 12,000 people. Yes, I was nervous. However, connecting with those graduates that day was a peak experience. And to see how many people have watched it since on YouTube was definitely unexpected.
What are you wearing? So glad you asked. Gold boots by Bay Area designer Martha Davis, clothes styled by my friends Kelly Sparks and Kat Yeh of StyleKouncil, and my hair and makeup were done by Persia Matine, who does the best work in the Bay Area; all can be found on my website.
Did you expect the Webby Awards to have such staying power? When I first saw the web, I knew it would change the world. I worked hard establishing the Webby Awards for its first decade as I saw how the web was changing our lives. And as the technology continues to change, I believe the Webbys will continue to honor technology even if it grows beyond the web—just as the Grammys are named after the gramophone.
Your last two films premiered at Sundance; are you working on anything new? I have a new feature documentary that is almost complete called Connected: A Declaration of Interdependence. It addresses the Internet and the way it's changing our lives. It also tells a personal story about my own experience of connectedness.
You have a film at the Guggenheim Museum? Ken, my husband, and I wrote a short script called "Yelp: With Apologies to Allen Ginsberg's 'Howl'." My team and I turned it into a film and were all thrilled to hear it was selected out of 23,000 entries to make the first round of a competition that the Guggenheim Museum and YouTube conducted this year. Its basic message is "don't forget to unplug" occasionally.
While your list of achievements is long, anything you want to improve on? My husband and I try to do technology Shabbats. Not that it always works, but we try. As wired as we are, I know life is better when we unplug one day a week.
What's your favorite drink and where do you like to drink it? Having a margarita, watching the sunset with my family in Hana, Maui.

CORPORATE PROFILE OF:
Advancing science and healthcare: a shared goal
We all have an important role to play in the STM community: scientists, researchers, authors, editors, doctors, nurses and allied health practitioners, librarians and publishers.
While relationships and traditions evolve, our shared goal remains constant. As one community, we serve society through the advancement of scientific and medical research and practice.
Publishers play an important role. We ensure the integrity of content and nurture new paths of exploration, extend access to vital information and preserve knowledge for generations to come. For Elsevier, linking researchers and practitioners with the sophisticated resources and information they need is both our core business mission and a profound responsibility.
Scientists advancing science
Scientific and healthcare research is growing rapidly, with ever-increasing amounts of information being published each year. Today, millions of researchers around the globe rely on approximately 18,000 peer-reviewed journals containing 1.4 million articles.
Scientists rely on these reputable journals to aggregate, filter and validate author submissions independent of any outside influence or interested third party. At Elsevier, independent editors and editorial boards decide whether or not to publish an author's work based upon its quality, novelty and relevance for the publication. And, as scientific research steadily grows, new fields of inquiry and exploration develop.
The creation of new STM journals helps to nurture these emerging fields by providing scientists and researchers with a forum to establish the field's identity, focus and validity. Elsevier has supported this need by launching new journals every year for more than five decades. Many have helped to define new disciplines and sub-disciplines.
Sharing the world's STM information
Today there is greater access to and more efficient usage of scientific information by more scientists than ever before. STM publishers have collaborated on industry standards and invested substantially in new technologies to allow scientists and practitioners the ease and ability to access, cross-reference, organise and share the world's STM information, anytime, anywhere. Elsevier has invested hundreds of millions to digitise the content of all its journals, develop new products and enhance functionality and access.
As a result, more than 10 million scientists worldwide now access, via ScienceDirect, millions of Elsevier articles and abstracts as well as the content of other STM publishers through the free linking system CrossRef. Scientists are not only accessing a wealth of information, but they are searching and locating the content they need faster and easier with the new navigation tool Scopus, which they helped to develop with Elsevier. Past, present and future scholars are now seamlessly connected to vital information.
STM publishers have also collaborated on initiatives to bridge the information divide around the globe. Two UN projects are making sustainable progress toward that goal. For example, WHO-led HINARI (Health InterNetwork Access to Research Initiative) provides public institutions in developing countries with online access to the major journals of the biomedical and related social sciences. Inspired by this success, the Food and Agricultural Organization's AGORA project (Access to Global Online Research in Agriculture) is linking researchers, policy makers, educators, technical workers and extension specialists in developing countries with high quality, relevant information in agriculture and related fields. Elsevier is proud to be a founding publisher of both initiatives.
Documenting the 'minutes of science' for past, present and future
Elsevier is committed to ensuring that scientists and researchers have enduring access to the scientific scholarship we publish. Our journal programmes record the 'minutes of science', and we recognise our responsibilities as the keeper of those 'minutes' in our policies regarding copyright, archiving and the historic record of the transactions of scholarship.
In 2002, Elsevier and the National Library of the Netherlands (Koninklijke Bibliotheek) reached a groundbreaking agreement in electronic archiving. The Library is now the first official digital archive of all Elsevier journals, ensuring permanent access to critical scientific and medical research.
One community, one calling
For more than a century, Elsevier has been dedicated to fuelling a continuous cycle of exploration and discovery and to accelerating the transformation of ideas into actions. The STM community is a network that fosters the creation of knowledge, links cultures and peoples, and brings understanding and hope. At Elsevier we believe that getting the right information into the right hands, at the right time, can make a difference.
A Book in Your Name - helping to fill the shelves of university libraries across the developing world
In 2005, Elsevier marks the 425th anniversary of the establishment of the House of Elzevir, university printer/ publisher of seminal works including those by Descartes and Galileo; and the 125th birthday of the modern company Elsevier, named to honour the tradition of excellence of the House of Elzevir.
To commemorate our double birthday, Elsevier launched a book donation programme to help fill the shelves of university libraries across the developing world. Designed by employees for employees, 'A Book in Your Name' invited all Elsevier colleagues to select one of 10 libraries to receive a book donated by Elsevier. An external Advisory Panel of librarians collaborated with Elsevier to choose needy libraries in Africa, Latin America and Asia that would make excellent use of the donated books.
As a result, each library will receive a core collection of 670 books representing essential STM titles from Elsevier's catalogue. They include such influential and widely used works as Gray's Anatomy, Fundamentals of Neuroscience and Cecil Essentials of Medicine. A total donation of 6,700 books is being shipped, valued at approximately US$1 million.

Q: Form Submit Button Works, but not Submit() in Link I've done this so often before on different websites, but can't get it to work now.
I've got a simple form that posts perfectly well using a submit button, but for a specific reason I actually need it to submit via a url link instead.  I'm using submit().  The form submits, but the data isn't posting.
What am I missing?

<?
if(isset($_POST['bar'])) { echo 'testing button
'; }
if(isset($_POST['information'])) {
    echo $_POST['information'];
    echo '
Info successfully posted.';
    }
?>

        <input type="submit" name="bar" value="Send">

        Confirm and Post

        Post Directly
    </form>

A: The form starts to submit, then the href of the link is followed, and this cancels the form submission.
If you are using old-style onclick attributes, then return false; at the end to prevent the default action.
You would, however, be better off using a submit button (you are submitting a form). You can use CSS to change its appearance.

A: Try this code :

        <?php
        if (isset($_POST['bar'])) {
            echo 'testing button
';
        }
        if (isset($_POST['information'])) {

New procedure enhances production of perovskite solar cells
By Jack Thomas
© iStock/Tsvetan Ivanov
A team of scientist have developed a method that boosts the manufacturing efficiency of perovskite solar cells, making them more commercially viable.
The NYU Tandon School of Engineering team has created a novel technique that significantly accelerates the p-doping process of producing perovskite solar cells – a major bottleneck in the building procedure – making the cells economical and efficient.
The research is published in the journal Nature.
Throughout the last 15 years, the technology of perovskite solar cells has advanced dramatically, with their power conversion efficiency increasing from 3% to 25.5%, making their performance comparable with photovoltaic cells.
However, one obstacle that persists is the arduous p-doping process – attained through the ingress and diffusion of oxygen into the hole transporting layer – which can take many hours or even days to complete, meaning producing perovskite solar cells on a mass scale is uneconomical. To combat this issue, the team has created a new method that accelerates this process by utilising carbon dioxide instead of oxygen.
Traditional perovskite solar cells require doped organic semiconductors for the charge-extraction interlayers that are interspersed between the electrodes and the photoactive perovskite layer. Traditionally, these interlayers are doped through the implementation of lithium bis(trifluoromethane)sulfonamide (LiTFSI), a lithium salt, to spiro-OMeTAD, a π-conjugated organic semiconductor widely used for a hole-transporting material in perovskite solar cells. Finally, the doping process is commenced by exposing spiro-OMeTAD: LiTFSI blend films to light and air.
This process is exceptionally impractical not only from a time perspective but also because ambient conditions are crucial to successfully conducting it; contrastingly, the new method involves bubbling a spiro-OMeTAD: LiTFSI solution with CO2 under ultraviolet light and has proved to considerably more efficient. The electrical conductivity of the interlayers exhibited a 100 times increase compared to a pristine blend film, approximately ten times higher than that attained from an oxygen bubbling process, achieving high efficiency and stability in perovskite solar cells with no need for post-treatment.
Jaemin Kong, a post-doctoral associate and lead author of the study, said: "Besides shortening the device fabrication and processing time, application of the pre-doped spiro-OMeTAD in perovskite solar cells makes the cells much more stable. That's partly because most of the detrimental lithium ions in the spiro-OMeTAD: LiTFSI solution were stabilised as lithium carbonates during the CO2 bubbling process. Thus, we can obtain fairly pure doped organic materials for efficient hole transporting layers."
Additionally, the team determined that their CO2 doping method can be utilised for p-type doping of different π-conjugated polymers, such as PTAA, MEH-PPV, P3HT, and PBDB-T.
André D. Taylor, an associate professor from the Department of Chemical and Biomolecular Engineering, said: "We believe that wide applicability of CO2 doping to various π-conjugated organic molecules stimulates research ranging from organic solar cells to organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs) even to thermoelectric devices that all require controlled doping of organic semiconductors.
"At a time when governments and companies alike are now looking to reduce CO2 emissions if not de-carbonise, this research offers an avenue for reacting large amounts of CO2 in lithium carbonate to improve next-generation solar cells, while removing this greenhouse gas from the atmosphere," he explained, adding that the idea for this novel approach was a counterintuitive insight from the team's battery research.
"From our long history of working with lithium-oxygen/air batteries, we know that lithium carbonate formation from exposure of oxygen electrodes to air is a big challenge because it depletes the battery of lithium ions, which destroys battery capacity. In this Spiro doping reaction, however, we are actually exploiting lithium carbonate formation, which binds lithium and prevents it from becoming mobile ions detrimental to the long-term stability of the Perovskite solar cell. We are hoping that this CO2 doping technique could be a stepping stone for overcoming existing challenges in organic electronics and beyond."

You will be notified of our decision in writing, as review decisions are not provided over the phone.
LLB operates a selective licensing program, and not all applicants are awarded a license. If you are offered a license agreement, you will be required to obtain standard product liability insurance, cyber liability insurance, and pay an annual advance and or guarantee of royalties.
Little League requires all products to be evaluated as part of the licensing application process. This may be in addition to laboratory testing for specific products such as baseballs. A product review fee may be required. The fee is non-negotiable and non-refundable. Fees start at $500 but may vary depending on the product review process as detailed in the licensing application and will be communicated upon thorough review of the licensing application.
For more information or to send your licensing application, please contact licensing@LittleLeague.org.
Endemic Equipment License
The proper approach to establishing a licensing agreement for equipment begins with forwarding appropriate fliers and information on the equipment proposed for licensing to the Marketing Department in Williamsport. If the printed material forwarded qualifies for further review, you will be notified by the Marketing Department.
Fees associated with the evaluation process and specific royalties that apply to each category of equipment can be discussed with the Marketing Department. The licensing agreement is in effect from October 1st of each calendar year through September 30th of the following calendar year. It is required of the licensee that the Sales and Royalty report, which will be forwarded to you prior to the end of each quarter, be completed and submitted fifteen days after the end of each quarter.
By mid-summer of each year you are notified by the Marketing Department of the need to renew the licensing agreement, which expires on September 30th of each year. A simple signature renews the licensing agreement and is then accompanied by the advance royalty for the upcoming year.

I built this TARDIS table lighter, over the course of the last month, or so. I was really happy (and surprised) with how well it turned out.
I might make more to sell, although I am as yet undecided. If you're a smoker, or would otherwise be interested in buying a table lighter, and are a Doctor Who fan, I'd appreciate any input (via private message, so as not to skew others' opinions) as to what you think you would be willing to pay for such an item. I'm not asking for any sort of commitment; it's not a 'bid'. I'd just like to gauge whether or not I would be able to charge enough for these to make building more worth my while.
I probably spent around 75 hours on this, although a lot of that time was redundant, trying to figure out the best way to accomplish various aspects of the construction.
The photo descriptions are getting cut off in the embedded album, so if you care to read them, you can access the album on imgur directly here.

The former head of Nissan has presented new charges
Carlos Ghosn was able to steal a large sum as a result of fraudulent scheme to transfer money from Nissan Oman to the firms trading machines.
The Tokyo district public Prosecutor indicted former head of the automobile Alliance Renault – Nissan – Mitsubishi Carlos Ghosn new charges of misappropriation of funds of the concern Nissan. On it informs TV channel NHK on Monday, April 22.
It is alleged that about 5 million dollars could be stolen as a result of the fraudulent scheme to transfer money from Corporation to Oman at the current there firms to trade cars.
Earlier Gun was charged with three charges of misappropriation or unlawful use of vehicles Nissan.
Also on Monday will expire on a specific court the tenure of Carlos Ghosn in custody. The new charge allows you to leave it in a jail cell, but lawyers for former Manager intend to immediately apply to the court with a lawsuit demanding his release on bail.
Recall, November 19, 2018, Carlos Ghosn and his colleague Greg Kelly was detained in Tokyo. The rut was accused of understating the size of his five-year remuneration of half – a $44 million, and Kelly is aiding the Rut. Also, according to the investigation, Ghosn moved to Nissan their personal financial losses from a failed securities transactions in 2008.
Already on 22 November, the Board of Directors of Nissan voted for the resignation of Ghosn as Chairman of the group and the dismissal of Kelly.
In late January, Carlos Ghosn resigned from the post of President of Renault.
Kelly was released on bail late last year. But on March 6, gon was released from prison on bail of $9 million, however, on 4 April he was again arrested in connection with the new allegations of fraud.
