Senate Democrats seek greater safeguards for keyless ignitions
Eric Kulisch
In a letter to NHTSA Deputy/Acting Administrator Heidi King in May, Blumenthal and Markey suggested automakers could install the shut-off feature for about $5 per vehicle.
WASHINGTON -- New Senate legislation introduced Friday aims to prevent carbon monoxide poisoning and rollaway accidents in vehicles with keyless push-button start.
The proposal by Sens. Richard Blumenthal, D-Conn., and Edward Markey, D-Mass., would force NHTSA to issue regulations requiring automatic shut-off features and set a performance standard for powering down a vehicle when it's not in park mode. They say the nation's top auto safety agency has dragged its feet addressing the problem and that automakers have not done enough to protect consumers.
Last May, a New York Times investigation identified 28 fatalities and 45 injuries since 2006 connected to carbon monoxide from keyless-ignition vehicles left running in a home garage. Smart-key technologies are standard equipment on 62 percent of new vehicles, according to consumer information website Edmunds.
The car recognizes a fob transmitting a radio-frequency ID signal when close by, allowing the doors to be opened and the car started with the push of a button. Because of quieter engines and no physical key, many people forget to shut off the engine or try to stop the engine while still in drive or neutral mode.
More alerts?
Since 2011, NHTSA has been considering a rule that would standardize the length of time someone must hold down the control button to shut off the engine and require more internal and external alerts when someone exits the vehicle while it's still running or not in the park setting.
The Protecting Americans from the Risks of Keyless Ignition Technology (PARK IT) Act goes further by requiring automakers to include an automatic shut-off capability. In a letter to NHTSA Deputy/Acting Administrator Heidi King in May, the two senators suggested automakers could install the shut-off feature for about $5 per vehicle. That's the amount General Motors said in a report to NHTSA in 2015 that it cost to retrofit an existing vehicle with automatic shut-off.
"NHTSA, our automobile safety cop on the beat, must ensure that novel transportation technologies help eradicate the auto safety challenges of the 20th century, not pose additional dangers in the 21st century," Markey said in a statement. "With deaths attributable to keyless ignitions mounting, it's time for NHTSA to set safety standards to prevent carbon monoxide poisoning and vehicle rollaways."
NHTSA, industry respond
NHTSA, in a statement, said its ongoing safety education efforts include keyless ignition systems.
"We prioritize safety in everything that we do, including in the agency's actions to address risks associated with keyless ignition systems," the agency said. "To help educate consumers, the agency produced an awareness campaign highlighting the proper way to operate vehicles with keyless ignition systems and providing drivers tips to prevent dangerous situations from occurring."
Most vehicles include warnings when the engine is left running, but they vary by intensity and type. Blumenthal and Markey praised GM and Ford Motor Co. for adding automatic shut-off in some models.
The Alliance of Automobile Manufacturers issued this statement to Automotive News in response to the proposed legislation:
"Current keyless ignition system designs generally follow the recommended practices of the Society of Automotive Engineers, addressing operating logic, indication of vehicle ignition/control status and the physical control characteristics of keyless ignition systems. SAE recommendations also focus on uniform labeling to help provide consumers with a better understanding of how keyless systems function."
Federal safety standards already address brake transmission shift interlocks, it added.

Q: An RPM spec file %pre section that reinstalls a dependant package? I am revising one of our in-house RPMs that adds to the nagios package.
Originally our package would alter some files that were installed by nagios.
My new package undoes this methodology and takes an additive approach.
Is it possible to do something like this in the %pre section?
%pre
rpm --erase nagios
rpm --install nagios

When I run this it hangs here:
warning: waiting for transaction lock on /var/lib/rpm/__db.000

*

*John

A: No way that I am aware of. If you need to do something special when nagios is modified, you can use %triggerin and %triggerout. I believe %triggerin will be executed when you install your RPM if nagios is already installed, but I don't remember offhand where in the sequence it will happen.

\section{Introduction}

The recent upsurge of interest in non-relativistic
conformal symmetries \cite{Hen,LSZGal,moreconf,DHNC} directed
attention to their role in getting a deeper understanding, and in
physical applications \cite{Hen}.
In this Note we add another example to the list. To be specific, we  explain some interesting properties of the
non-linear Schr\"odinger equation  (NLS) using these
symmetries.

\goodbreak
\section{The NLS with a position and time-dependent non-linearity}

Le us study  the cubic NLS
\begin{equation}
iu_t+u_{xx}+F(t,x)\vert u\vert^2u=0,
\label{2.1}
\end{equation}
where $u=u(t,x)$ is a complex function in $1+1$ space-time dimension.
Such an equation arises, for example, in some approaches to
the  Quantum Hall Effect  \cite{AGJPS}.

When  $F(t,x)$ is a
constant, this is the usual NLS, which is known
to be integrable. But what happens, when
 the coefficient
$F(t,x)$ is a {\it function} rather then just a constant~?

A useful test of integrability is provided by
the \textit{Painlev\'e test  of Weiss, Tabor and Carnevale}
\cite{WTC}. (The procedure is reminiscent of the Frobenius' method used for ODEs).

Let us recall the definition and some properties. For a full account, the Reader is advised to consult \cite{W1}.
Consider a system
of partial differential equations (PDEs), and let us assume that its
solutions are given by a meromorphic function of the
complex veriables $z_1,\dots, z_n$.  The singularities
of such a function belong to a manifold (called the singular manifold) of dimensions
$2n-2$, given by equations of the form
$
\Phi(z_1,\dots,z_n)=0,
$
where the $\Phi$ are analytical.

Then our PDE  is said to have the
\textit{Painlev\'e property} if
all of its solutions can be written, in a neighbourhood of
the singular manifold, as a generalized  Laurent series,
\begin{equation}
u(z_1,\dots,z_n)=\Phi^{\alpha}\sum_{j=0}^\infty
u_j(z_1,\dots,z_n)\Phi^j,
\label{Lexpan}
\end{equation}
where $\alpha$ is a negative integer and the $u_j(z_1,\dots,z_n)$ s are analytical.
Then the Painlev\'e conjecture of WTC \cite{WTC} says that
\textit{a PDE which has the Painlev\'e property is integrable} i.e. can be solved by inverse scattering.

Inserting the expansion (\ref{Lexpan}) into our PDE fixes the value of $\alpha$, and then provides us with
recurrence relations for the functions $u_j$. For some value of $j$ called resonances, $u_j$ remains undetermined,
and the system has to satisfy consistency conditions.

Truncating the series may provide us with a B\"acklund transformation \cite{W1}. For example, one can generate
Jackiw-Pi vortex solutions from the vacuum \cite{HYPRD}.

Returning to the NLS, below we show

\parag\underbar{Theorem1}~:
{\it The generalized non-linear Schr\"odinger equation (\ref{2.1})
only passes the Painlev\'e test  of Weiss, Tabor and Carnevale}
\cite{WTC}
{\it if the coefficient of the non-linear term
is}
\begin{equation}
F(t,x)=\frac{1}{a+bt},
\qquad
a, b={\rm const}.
\label{2.2}
\end{equation}
\parag\underbar{Proof}.
As it is usual in studying non-linear Schr\"odiger-type equations
\cite{W1,CLACO}, we consider Eqn. (\ref{2.1}) together with its complex conjugate ($v=u^*$),
\begin{equation}
\begin{array}{lll}
 iu_t+u_{xx}+Fu^2v&=&0,
\\[6pt]
-iv_t+v_{xx}+Fv^2u&=&0.
\end{array}
\label{2.3}
\end{equation}
This system will pass the Painlev\'e  test if $u$ et $v$
have generalised Laurent series expansions,
\begin{equation}
u=\sum_{n=0}^{+\infty}u_n\xi^{n-p},\qquad
v=\sum_{n=0}^{+\infty}v_n\xi^{n-q},
\label{2.4}
\end{equation}
($u_n\equiv u_n(x,t)$, $v_n\equiv v_n(x,t)$ and $\xi\equiv\xi(x,t)$)
in the neighbourhood of the singular manifold $\xi(x,t)=0$,
$\xi_x\not=0$,
with a sufficient number of free
coefficients. Owing to a results of  Weiss, and of Tabor \cite{W1,TAB},
it is enough to consider
$
\xi=x+\psi(t).
$  Then $u_n$ and $v_n$ become functions de $t$ alone,
$u_{n}\equiv u_{n}(t),\
v_{n}\equiv v_{n}(t).
$
Checking the dominant terms,
$u\sim u_0\xi^{-p}$, $v\sim v_0\xi^{-q}$,
using the above remark, we get
\begin{equation}
p=q=1,
\qquad
F\,u_0v_0=-2.
\label{2.6}
\end{equation}
Hence  $F$ can only depend on $t$.
Now inserting the developments (\ref{2.4}) of $u$ and $v$ into (\ref{2.3}),
the terms in $\xi^k$, $k\geq -3$ read
\begin{equation}
\begin{array}{ll}
& i\Big(u_{k+1,t}+(k+1)u_{k+2}\xi_t\Big)+(k+2)(k+1)u_{k+3}
 +F\Big(\sum_{i+j+l=k+3}u_iu_jv_l\Big)=0,
 \\[6pt]
& i\Big(v_{k+1,t}+(k+1)v_{k+2}\xi_t\Big)-(k+2)(k+1)v_{k+3}
 -F\Big(\sum_{i+j+l=k+3}v_iv_ju_l\Big)=0.
 \end{array}
 \label{2.7}
\end{equation}
(Condition  (\ref{2.6})  is recovered for $k=-3$).
The coefficients $u_n$, $v_n$ of the series (\ref{2.3}) are
given by the system $S_n$ ($k=n-3$),
\begin{equation}
\begin{array}{ll}
&[(n-1)(n-2)-4]u_n+Fu_0^2v_n=A_n,
\\[6pt]
& Fv_0^2u_n+[(n-1)(n-2)-4]v_n=B_n,
\end{array}
\label{2.8}
\end{equation}
where $A_n$ et $B_n$ only contain those terms $u_i$, $v_j$ with
$i,j<n$. The determinant of the system is
\begin{equation}
\det S_n=n(n-4)(n-3)(n+1).
\label{2.9}
\end{equation}
Then (\ref{2.3}) passes the Painlev\'e test if, for each $n=0,3,4$,
one of the coefficients $u_n$, $v_n$ can be arbitrary.
For $n=0$, (\ref{2.6}) implies
that this is indeed true either
for  $u_0$ or $v_0$.
For $n=1$ and $n=2$, the system (\ref{2.7})-(\ref{2.8}) is readily solved, yielding
\begin{equation}\begin{array}{ll}
&u_1=-\frac{i}{2}u_0\xi_t,
\qquad
v_1=\frac{i}{2}v_0\xi_t,
\\[6pt]
&6v_0u_2=iv_{0,t}u_0+2iu_{0,t}v_0-\frac{1}{2}u_0v_0(\xi_t)^2,
\\[6pt]
&6u_0v_2=-iu_{0,t}v_0-2iv_{0,t}u_0-\frac{1}{2}u_0v_0(\xi_t)^2.
\end{array}
\label{2.10}
\end{equation}
$n=3$ has to be a resonance; using condition (\ref{2.6}),
the system (\ref{2.8}) becomes
$$
\begin{array}{l}
-2v_0u_3-2u_0v_3=A_3v_0,
\\[6pt]
-2v_0u_3-2u_0v_3=B_3u_0,
\end{array}
$$
which requires $A_3v_0=B_3u_0$.
But using the expressions of $A_{3}$ and $B_3$, with the
help of ``Mathematica'' we find
$$
2FA_3=u_0(F_t\xi_t-F\xi_{tt}),\qquad u_0F^2B_3=F\xi_{tt}-F_t\xi_t,
$$
so that the required condition indeed holds.

$n=4$ has also to be a resonance;  we find, as before,
$$
\begin{array}{ll}
2v_0u_4-2u_0v_4&=A_4v_0,
\cr
-2v_0u_4-2u_0v_4&=B_4u_0,
\end{array}
$$
enforcing the relation
$
v_0A_4=-u_0B_4.
$
Now using the expressions of
$v_0$, $u_1$, $v_1$, $u_2$, $v_2$ as functions of $u_0$, $F$,
$u_3$, $v_3$,  ``Mathematica'' yields
$$
\begin{array}{ll}
6u_0F^2A_4=
&-F^2u_{0,t}^2-2iu_0^2F^2\xi_t\xi_{tt}+u_0F^2u_{0,tt}
+iu_0^2F\xi_t^2F_t-u_0Fu_{0,t}F_t
+2u_0F_t^2-u_0^2FF_{tt},
\\[8pt]
3u_0^3F^3B_4=
&-F^2u_{0,t}^2-2iu_0^2F^2\xi_t\xi_{tt}+u_0F^2u_{0,tt}
+iu_0^2F\xi_t^2F_t-u_0Fu_{0,t}F_t
-4u_0F_t^2+2u_0^2FF_{tt}.
\end{array}
$$
Then our constraint implies that
\begin{equation}
2F_t^2-FF_{tt}=0.
\end{equation}
Thus
$\big(F^{-1}\big)_{tt}=0$,
so that $F^{-1}(x,t)=a+bt$, as stated.

For $b=0$,
$
F(t,x)
$
in Eqn. (\ref{2.1}) is a constant,
and we recover the constant-coefficient NLS with its known solutions.
For $b\neq0$, the equation becomes explicitly time-dependent.
Assuming,
for simplicity, that $a=0$ and $b=1$, it reads
\begin{equation}
iu_{t}+u_{xx}+\frac{1}{ t}\vert u\vert^2u=0.
\label{2.13}
\end{equation}

This equation can also be solved. Generalizing the usual
travelling soliton, let us seek, for example,
 a solution of the form
\begin{equation}
u_0(t,x)
e^{i(x^2/4t-1/t)}\,f(t,x),
\label{2.14}
\end{equation}
where $f(t,x)$ is some real function. Inserting the  Ansatz
(\ref{2.14}) into (\ref{2.13}), a routine calculation yields the soliton
\begin{equation}
u_0(t,x)=\frac{e^{i(x^2/4t-1/t)}\,}{\sqrt{t}}\,
\frac{\sqrt{2}}{\cosh\big[x/t+x_{0}\big]}.
\label{2.18}
\end{equation}
Interestingly, the steps leading to (\ref{2.18}) are essentially the same as
those met when constructing travelling solitons for the ordinary NLS ---
and this is not a pure coincidence~:

\parag\underbar{Theorem2}.
\begin{equation}
u(t,x)=\frac{1}{\sqrt{t}}\exp\Big[\frac{ix^2}{4t}\Big]\,
U\big(-{1/t},-{x/t}\big)
\label{2.19}
\end{equation}
{\it satisfies the time-dependent equation (\ref{2.13})
if and only if
$U(t,x)$ solves Eqn. (\ref{2.1}) with $F=1$}.
\goodbreak
\vskip2mm
This can readily be proved by a direct calculation. Inserting (\ref{2.19})
into (\ref{2.13}), we find,
\begin{equation}
iu_{t}+u_{xx}+\frac{1}{ t}\vert u\vert^2u=
t^{-5/2}\exp\Big[\frac{ix^2}{4t}\Big]\,\bigg(
iU_{t}+U_{xx}+\vert U\vert^2U\bigg),
\end{equation}
proving our statement.

Our soliton (\ref{2.18}) constructed above comes in fact from the
well-known ``standing soliton'' solution of the NLS,
\begin{equation}
U_{0}(t,x)=\frac{\sqrt{2}\,e^{it}}{\cosh[x-x_{0}]}\ ,
\label{2.20}
\end{equation}
by the transformation (\ref{2.19}). More general solutions
could be obtained starting with the travelling soliton
\begin{equation}
U(t,x)=e^{i(vt-kx)}\frac{\sqrt{2}\,a}{\cosh[a(x+kt)]},
\qquad
a=\sqrt{k^2+v}.
\label{2.21}
\end{equation}

\section{Non-relativistic conformal transformations}

Where does the formula (\ref{2.19}) come from~?
To explain it, let us remember
that the non-linear space-time transformation
\begin{equation}
D:\left(\begin{array}{c}
t\\ x
\end{array}\right)
\to
\left(\begin{array}{c}
-\displaystyle{1/t}\\
-\displaystyle{x/t}
\end{array}\right)
\label{3.1}
\end{equation}
has already been met in a rather different context, namely
in describing planetary motion when the gravitational ``constant''
changes inversely with time, as suggested by Dirac \cite{DIR}. Then
one shows that
\begin{equation}
\vec{r}(t)=t\,\vec{r}^*\big(-{1/t})
\label{3.2}
\end{equation}
describes  planetary
motion with Newton's ``constant'' varying as
$
G(t)={G_0}{ t},
$
whenever
$\vec{r}^*(t)$ describes ordinary planetary motion, i.e. the one
with a constant gravitational constant, $G(t)=G_0$ \cite{DGH}
\footnote{Curiously, the {\it same} transformation is used to transform  supernova explosion into implosion,
\cite{ORS,HH}.}.

The strange-looking transformation (\ref{3.1}) is indeed related to the
conformal structure of non-relativistic space-time \cite{DHNC,DGH,DBKP,Henkel}.
It has been noticed a long time ago \cite{JNH}, that the
``conformal''
space-time transformations
\begin{equation}\left\{\begin{array}{lllllll}
\left(\begin{array}{c}t\\ x\end{array}\right)
&\to&
\left(\begin{array}{c}
T\\
X\end{array}\right)&=&
\left(\begin{array}{c}
\displaystyle{\delta^2}t
\\
\displaystyle{\delta}\, x
\end{array}\right),
\qquad
&0\neq\delta\in\IR
&\hbox{dilatations}
\\[8pt]
\left(\begin{array}{c}t\\ x\end{array}\right)
&\to&
\left(\begin{array}{c}T\\ X\end{array}\right)
&=&
\left(\begin{array}{c}
\displaystyle\frac{t}{1-\kappa t}
\\[6pt]
\displaystyle\frac{x}{1-\kappa t}
\end{array}\right),
\qquad
&
\kappa\in\IR
&\hbox{expansions}
\\[8pt]
\left(\begin{array}{c}t\\ x\end{array}\right)
&\to&
\left(\begin{array}{c}T\\ X\end{array}\right)
&=&
\left(\begin{array}{c}t+\epsilon\\ x\end{array}
\right),
\qquad
&\epsilon\in\IR
&\hbox{time translations}
\end{array}\right.
\label{3.4}
\end{equation}
implemented on wave functions according to
\begin{equation}
U(T,X)=\left\{
\begin{array}{l}
\displaystyle{\delta}^{1/2}u(t,x)
\\[8pt]
(1-\kappa t)^{1/2}\exp
\Big[i\displaystyle\frac{\kappa x^2}{4(1-\kappa t)}\Big]u(t,x)
\\[8pt]
u(t,x)
\end{array}\right.
\label{3.5}
\end{equation}
permute the solutions of
 the free Schr\"odinger equation.
In other words, they are {\it symmetries} for the free Schr\"odinger
equation. (The generators in (\ref{3.4}) span in fact an ${\rm SL}(2,\IR)$
group; when added to the obvious galilean symmetry,
the  Schr\"odinger group is obtained.
A Dirac monopole, an Aharonov-Bohm
vector potential, and an inverse-square potential can also be included,
\cite{Jmon,DGH,DHP}).

The  transformation $D$ in Eqn. (\ref{3.1}) belongs to
this symmetry group: it is in fact
 (i)  a time translation with
$\epsilon=1$, (ii) followed by an expansion with
$\kappa=1$, (iii) followed by a second time-translation with
$\epsilon=1$.
It is hence a symmetry for the free (linear) Schr\"odinger
equation. Its action on $\psi$, deduced from (\ref{3.5}), is precisely (\ref{2.19}).

The cubic NLS with non-linearity $F={\rm const}$.
 is not more $SL(2,\IR)$ invariant \footnote{
Galilean symmetry can be used to produce further
solutions --- just like the travelling soliton (\ref{2.21}) can be
obtained from the ``standing one'' in (\ref{2.20}) by a galilean boost.
Full Schr\"odinger invariance yielding expanded and dilated solutions
can be restored by replacing the cubic non-linear term by
the fifth-order non-linearity $\vert\psi\vert^4\psi$.
These statements about non-invariance assume  restricting ourselves to certain representations, see \cite{StoHe}.}.
In particular, the
 transformation $D$ in (\ref{3.1}), implemented as in Eq.
 (\ref{2.19}) carries the cubic term into the
time-dependent term
$(1/t)\vert u\vert^2u$ --- just like Newton's gravitational potential
$G_{0}/r$ with $G_0={\rm const}$. is carried into the time-dependent
Dirac expression $t^{-1}G_{0}/r$ \cite{DGH}.

Similar arguments explain the integrability of other NLS-type
equations. For example, electromagnetic waves in a non-uniform
medium propagate according to
\begin{equation}
iu_{t}+u_{xx}+\big(-2\alpha x+2\vert u\vert^2\big)u=0,
\label{3.6}
\end{equation}
which can again be solved by inverse scattering   \cite{CL}.
 This is explained by observing that the potential term here
can be eliminated by  switching to a uniformly accelerated frame:
\begin{equation}
\begin{array}{ll}
&u(t,x)=\exp\big[-i(2\alpha xt+\smallover4/3\alpha^2 t^3\big]U(T,X),
\\[6pt]
&T=t,
\qquad
X=x+2\alpha t^2.
\end{array}
\label{3.7}
\end{equation}
Then $u(t,x)$ solves (\ref{3.6}) whenever $U(T,X)$ solves the free equation

iU_{t}+U_{xx}+2\vert U\vert^2U=0.

The transformation (\ref{3.7}) is again related to the structure of
non-relativistic
space-time. It can be shown in fact [10] that the (linear) Schr\"odinger
equation
\begin{equation}
iu_{t}+u_{xx}-V(t,x)u=0
\label{3.8}
\end{equation}
can be brought into the free form
$
iU_{T}+U_{XX}=0
$
 by a space-time transformation $(t,x)\to(T,X)$
if and only if the potential is
\begin{equation}
V(t,x)=\alpha(t)x\pm\frac{\omega^2(t)}{4}x^2.
\label{3.10}
\end{equation}

For the uniform force field ($\omega=0$)
the required space-time transformation is precisely (\ref{3.7}).
For the oscillator potential ($\alpha=0$), one can use rather
Niederer's transformation~\cite{NJP,DHP}
\goodbreak
\begin{equation}
\begin{array}{lll}
u(t,x)&=&\frac{1}{\sqrt{\cos\omega t}}\,
\exp\big[-i\frac{\omega}{4} x^2\tan\omega t\big]\,
U(T,X),
\\[12pt]
&&T=\displaystyle\frac{\tan\omega t}{\omega}
\qquad
X=\displaystyle\frac{x}{\cos\omega t}.
\end{array}
\label{3.11}
\end{equation}
Then
\begin{equation}
iu_t+u_{xx}-\frac{\omega^2x^2}{4}u
=
(\cos\omega t)^{-5/2}\,\exp\big[-i\frac{\omega}{4}\tan\omega t\big]
\Big(iU_T+U_{XX}\Big).
\label{3.12}
\end{equation}
Restoring the nonlinear term allows us to infer
that
\begin{equation}
iu_t+u_{xx}+\Big(-\frac{\omega^2x^2}{4}+\frac{1}{\cos\omega t}\,
\vert u\vert^2\Big)u=0
\label{3.13}
\end{equation}
is integrable, and its  solutions are obtained from those of
the ``free'' NLS by the transformation (\ref{3.11}).

\section{Discussion}

To conclude, we us mention
some more related results.

Firstly, our result should be compared with the
those of Chen et al. \cite{CLL}, who prove that the equation
\begin{equation}
iu_t+u_{xx}+F(\vert u\vert^2)u=0
\label{2.11}
\end{equation}
can be solved by inverse scattering
if and only if
$
F(\vert u\vert^2)=\lambda\vert u\vert^2,
$
 where $\lambda={\rm const}$. Note, however, that Chen et al. only
study the case when the functional $F(\vert u\vert^2)$
is independent of the space-time coordinates $t$ and $x$.

It has also been shown that the non-linear Schr\"odinger equation
with time--dependent coefficients,
\begin{equation}
iu_t+p(t)u_{xx}+F(t)\vert u\vert^2u=0,
\label{4.2}
\end{equation}
can be transformed into the constant--coefficient form
whenever \cite{GR}
\begin{equation}
p(t)=F(t)\left(a+b\int^tp(s)ds\right).
\label{4.3}
\end{equation}
This same condition, which could also be obtaind by a suitable
generalization of our approach, was found later as the one needed for
the Painlev\'e test \cite{JO} applied to Eq. (\ref{4.3}).

On  the other hand, the constant-coefficient, damped, driven NLS,
\begin{equation}
iu_t+u_{xx}+F(t)\vert u\vert^2u=a(t,x)u+b(t,x),
\label{4.4}
\end{equation}
was shown to pass the Painlev\'e test if
\begin{equation}
a(t,x)=\big({\smallover1/2}\partial_t\beta-\beta^2\big)+i\beta(t)
+\alpha_{1}(t)+\alpha_{0}(t),
\qquad
b(t,x)=0,
\label{4.5}
\end{equation}
\cite{CLA}, i.e., when the potential can be
transformed away by our ``non-relativistic conformal
transformations''.

We only studied the case of
$d=1$ space dimension.
Similar results would hold for any $d\geq1$.
It is worth noting that more general dynamical symmetries of the NLS under subalgebras of the Schr\"odinger/conformal algebra were studied systematically
   by S. Stoimenov and M. Henkel \cite{StoHe}.

At last, it is worth noting that the ``Kaluza-Klein-type''
framework, first proposed by Duval et al. \cite{DBKP,DGH}  has attracted
considerable recent attraction, namely in the
non-relativistic AdS/FCT context.  See, fore example,
\cite{DHH}.

Shaping for a Strike
Published: 1st April, 2021
Materials sent in printed form to all members of Leicester UCU eligible to vote, 30 March 2021.
Executives plead COVID-related delays for failing to publish their strategic vision for the University. But COVID has not caused any delays in planning to make 145 people redundant and separate them from their livelihoods.
If implemented, these badly thought-out business cases will do immense damage to our University and the students we care for.
Key workers – but redundant?
'Critical workers', such as library staff and maintenance staff, essential to campus infrastructure during the pandemic are now being made redundant. Ten FTE posts will be lost with the merger of Library staff and Student Services, losing a great deal of student-facing expertise. And the proposed redundancies in Estates will only make the appalling conditions in University-managed accommodation worse.
Educational experts within Leicester Learning Institute, such as curriculum designers and learning developers who created new ways of teaching to support the abstract 'Ignite' Dual Delivery approach, are now no longer necessary for helping Schools implement future high-level teaching policies. How will you reduce the BAME awarding gap? Or decolonise the curriculum? Or embed support for students from non-traditional backgrounds?
The end of a 'research-intensive' Leicester?
Why are certain researchers at risk? Many have strong track records
in authoring high-impact publications and in winning large grants. So why are researchers being forced into taking teaching-only contracts? What if it were your research career?
In the Department of Neuroscience, Psychology & Behaviour, 17 researchers are to be replaced with 8 staff on teaching-dominant contracts, including Professor Andrew Colman, who has worked at the university for more than 50 years. Also at risk are ambitious early- career scientists even though they bring in significant grant income. How can a University that seeks excellence as a 'research-intensive university make these scholars redundant?
This is damaging our University's reputation with the academic community and with the research councils who fund us.
In the School of Mathematics and Actuarial Science, the pure mathematics group is at risk. The London Mathematical Society (the UK's learned society for maths) hit back saying the Exec Board's plans are 'seriously flawed'. They – the experts in this – say that Mathematics 'is a continuum; what used to be called pure mathematics and applied mathematics are these days so closely intertwined as to be inseparable.' It is essential that, in research-intensive universities such as ours, teaching in fundamental mathematics must involve researchers of pure mathematics. The LMS further argued that 'in most universities, it is considered essential, a key part of the STEM ecosystem'. It lies at the heart of national strategies in several areas.
How can this be 'shaping for excellence'?
Hollow Governance, Fragile Finances
Our University is in crisis and now is the perfect moment to embrace change. The University of Leicester can recover and thrive. Or it might die. We – all of us who care about it and its future – must make decisions and act. We are the University.
These gamblers have charted a new course for our University. In 2017 they persuaded Council 'to accept and encourage an increased degree of risk' on our behalf. Since 2016, the institution's long-term debts have more than tripled, from approximately £76m to around £250m. These long-term liabilities include an off-balance sheet deal, to the value of £124m. The 'Freemens Common Village LLP' is a 'special purpose vehicle', created in 2019, whose stated goal is the building of student accommodation, teaching facilities and a carpark. But the structuring of the transaction involves the transfer of risk from private investors onto the University staff and its stakeholders.
As a result of this risk-taking, we are in danger. The University remains a 'going concern', but only just. According to the 2019/20 financial statements, it needs cash reserves of £30m to cover one month's outgoings. It has just £32m and has only managed this by taking on additional short-term debt, including deferring tax payments. In December 2020, it agreed further short-term lending from the Bank of England, under the Covid Corporate Financing Facility (CCFF), one of only three universities to have used this facility: it now owes the Bank of England £60m, which must be repaid within 12 months.
This short-term debt is likely due to their failure to renegotiate agreements with long-term creditors.
Yet, the Executive Board maintains that the reason for redundancies is not financially driven.
Who's to blame?
There is no transparency. Who has driven this risk-taking strategy? Who has reduced our resilience?
We believe current Chair of Council Gary Dixon has played a key role. He joined the University's supreme governing body in 2009, becoming Treasurer in August 2018 and then Chair a year later. Coincidently, he became Chair just as the Freemens Common special purpose vehicle came into existence. He boasts that his 'different experiences… may help shape the Council's thoughts in a different way to most of the members.' We are also concerned about the roles of the current Deputy Vice-Chancellor and Chief Operations Officer. Both are involved in the University's Finance Committee, and the Chief Operation Officer is a designated member of the Freemens Common LLP.
The role played by the present President and Vice-Chancellor is less clear. While he should not be judged by the failures of the previous VC, he has retained and even promoted at least five of his predecessor's lieutenants. In a nutshell, he has become part of the toxic Executive Board.
Redundancies will not save the Univeristy
#NoPlanNishan
With our University's finances so fragile, making redundant 145 colleagues might seem sad but unavoidable. However, the Vice-Chancellor and other members of his Executive Board have repeatedly denied that there is a financial motive. Instead, Professor Canagarajah insists, these redundancies are necessary to 'shape for excellence'.
No underpinning strategy has been shared with professional services departments or Schools. The pandemic has prevented its development, we've been told — though COVID hasn't hindered the creation of business cases for redundancy. A report on strategy was presented to Council on 19 March 2020. Our Freedom of Information request to see this report was denied on the grounds that, "We believe that premature disclosure of the report may have a negative effect on the reputation of the University, which in turn would detract potential students, detract investors, and give an unfair advantage to our rivals." How can a strategy be damaging to students and investors?
The VC insists that: "I don't want to be doing this again". Whilst leaders are soothing staff outside of the redundancy pools that they are 'not directly impacted', the financial statements warn us that 'further Mitigating Actions' might be required as "work is being undertaken to consider further savings".
Who will be next?
What has Leicester UCU been doing?
We've attended many, many collective and individual consultations to support every UCU member at risk of redundancy.
We have attended meetings with the Exec Board and Senate to put forward our cases.
We communicate regularly with our sibling unions, Unison, Unite and the students' union. All fully support us.
We are doing everything we can to publicise what's happening in local and national media and to mobilise support from professional associations, learned societies, editorial boards, alumni, students, external examiners, honorary graduates and others. We have lost count of the number of petitions and open letters that have been sent to the Vice-Chancellor in protest: the people objecting to his plans number in the tens of thousands. (See, for example, statements and letters from Centre for Medieval Studies, the Institute of Mathematics and its Applications, former members of the Department of Computing, and scholars of neurology, psychology and behaviour.)
We have written to members of the three main governing bodies, Council, Senate and Court, explaining why the executive's plans are so flawed. We have written to local politicians – Leicester's MPs, the mayor, city and county councillors – letting them know what's happening. It's their university too!
We have spent many hours digging into the University's accounts and minutes of Council and requesting information – trying to piece together the logics driving these processes.
Speak to your colleagues. Make sure they know how perilous the University's future is. Ask your head of school to challenge the Executive Board's plans in Senate – that's part of their role as 'custodian of the institution's academic integrity'!
Speak to anyone and everyone you know who might have some influence – your councillor, a faith leader, the chair of a community organisation or voluntary group. Ask them to raise their voice.
Vote in this ballot on industrial action. Vote YES for sustained strike action. Vote YES for sustained action short of a strike.
Get (more) involved in Leicester UCU.
Why strike?
We know from bitter experience that sometimes it's necessary to collectively stop working in order to strike against our employer. Sometimes only the threat of sustained strike action will force our employer to take seriously our concerns. In the summer of 2018, the University's senior managers –who included Burke and Riddleston – tried to sack more than 200 people. An overwhelming majority of Leicester UCU members voted to take strike action and our threat was enough to prevent all compulsory redundancies. We need a similarly credible threat now. We will only strike if necessary, but we will, if we have to.
Which side are you on?
Academic Freedom imperiled

Beverley is the county town and principal market town of the East Riding of Yorkshire.
The town is 8 miles north-north-west of Kingston upon Hull, 11 miles south of Driffield, 12 miles west-south-west of Hornsea, 19 miles south-west of Bridlington and 28 miles east-south-east of York.
Beverley started with a monastery in the 8th century and the town which developed saw early growth into one of the largest in the country through its wool trade and as a place of pilgrimmage for visitors to the tomb of St John of Beverley, still sited within the impressive Beverley Minster, which is among the country's finest church buildings.
At North Bar is the only surviving historic gateway from those which once guarded the entries to Beverley. It was built by the Town Council back in 1409.
The town has recently been remodelled creating a new Flemingate shopping centre with a hotel, cinema and a new pedestrian shopping street aligned towards the Minster but at the opposite side of the railway line to the traditional town centre, so as not to disturb the Georgian and Victorian buildings of the attractive main street and its Market Place which has an elaborate market cross, built in 1714, as its centrepiece.
Events in the town include a variety of festivals, usually including the Beverley Folk Festival at Beverley Racecourse, although this was cancelled in 2018; a Beverley Puppet Festival, next expected to take place in July 2020 Beverley Puppet Festival; a Beverley Food Festival in the Market Place; and a Christmas Festival of Food and Drink.
While the town is set in the landscape of the arable agriculture of the East Riding, the bread-basket of Yorkshire, Beverley can also count shipbuilding among one of its past staple industries. Boats, including many trawlers, were built in Beverley and were navigated down the River Hull to the port of Kingston upon Hull.
Beverley also has an aircraft named after it. The Blackburn Beverley transport aircraft were built at Brough, 10 miles south-west of Beverley, and flew between 1950 until being retired from Royal Air Force duties in 1967.
Beverley has a wide variety of shopping opportunities, from its Saturday and Wednesday markets and attractive traditional high street shopping to the new Flemingate shopping centre with its range of big name stores.
Beverley post office is in Register Square. There are also post offices branches in neighbouring villages.
Beverley has several pharmacies.
Pubs in Beverley range from refurbished old coaching inns to the modern real ale micropub.
The town offers quality eating from good pub food to dining at its inns and restaurants.
Beverley Library is at the Treasure House, Champney Road.
There is a museum and art gallery at the Treasure House, Champney Road. More details below.
For theatre details see below.
Westwood is one of Beverley's historic common pasture lands now acting as a vast open park near to the racecourse and with pleasant views across the town. The remains of two old windmills remain on the Westwood, one is at the location of the Beverley and East Riding Golf Club clubhouse.
Beverley Beck is a short canal, just under a mile long, which links Beverley to the navigable River Hull. The beck had been navigable from the 14th century, but became a canal when a lock and pump were installed in 1802 as part of a land drainage scheme.
The River Hull runs about a mile to the east of the town centre.
Beverley Tourist Information Centre is in Butcher Row.
The town has hotel and guest house accommodation and a youth hostel.
Beverley has public toilets with various limited opening hours at Dyer Lane, Lord Roberts Road and at railway and bus stations. Check times before you need to go at the public convenience finder of East Riding of Yorkshire Council.
Beverley has several schools.
Places of worship: Anglican, Catholic, Methodist, United Reformed, Baptist, other.
Beverley Minster, or the Parish Church of St John and St Martin, is built on the site of a monastery founded in the 8th century by John, Bishop of York, who died in Beverley in 721. He is credited with founding the town of Beverley. He became St John of Beverley after he was canonised more than 300 years after his death and the church is built around his tomb which was a place of pilgrimage. Work started on the present church after the collapse of the tower of the Norman church on the site in 1214. Saved by wealthy businessmen from destruction in the 16th century, the Minster saw restorations in the 18th and 19th century and around the turn of the 19th and 20th centuries more than 100 statues were placed on the west towers and other statuettes inside the minster together with new stained glass windows. The first of the statues, in 1897, was of Queen Victoria, to commemorate her Diamond Jubilee. Website
The year 1897 was also when the Roman Catholic Church of St John of Beverley was built in Victorian Gothic style just outside the North Bar gate at North Bar Without. The Roman Catholic diocese covering the whole of Yorkshire was from 1850 known as the Diocese of Beverley, although its cathedrals were in York. The diocese was split into the dioceses of Leeds and Middlesbrough in 1878, Beverley now being in the Diocese of Middlesbrough. Website
While Beverley Minster dominates one end of the town centre, Beverley also has a very impressive anglican parish church with great architectural interest at the other end of the town. St Mary's Church is situated at the junction of Hengate and North Bar Within. The building of the church started in 1120 and culminated in 1524 after the rebuilding of its tower which collapsed four years earlier. It was given a major restoration in the mid 19th century.

East Riding Theatre
Lord Roberts Road, Beverley
The East Riding Theatre, opened in December 2014 in what was originally built as a Baptist Chapel. It is run by a not-for-profit organisation supported by volunteers and provides an inspiring selection of theatre, music, comedy and literature. It also provides one of the venues of the annual Beverley Puppet Festival.
Beverley Racecourse
York Road about a mile from the centre of Beverley.
The racecourse holds regular race meetings in season and is also a venue for other events, including auctions. The racecourse traces its first grandstand back to 1767.
East Riding Treasure House and Beverley Art Gallery
Champney Road, Beverley
A collection of iron age swords found at South Cave in 2002 is among permanent exhibits at the museum, which also stages temporary exhibitions reflecting various aspects of the history of the East Riding. The museum is linked to a gallery with a collection of art works showing the great and the good of the East Riding.

Burton Constable
Burton Constable, Skirlaugh
Burton Constable is an Elizabethan mansion situated about 9 miles by road south of Hornsea and a similar distance north-east of Hull. Most of the house dates from 1560, although it includes part of a 12th century tower and remains of an earlier brick manor house from the late 15th century. Tours of the house explore up to 30 rooms fitted with original collections and interiors surviving from days as a much-loved family home. The house also has an 18th century orangery, gift shop, play area, gardens and parkland landscaped between 1772 and 1782 by Lancelot 'Capability' Brown. The stable block has been restored and its Great Barn exhibits the remains of a whale skeleton brought to Burton Constable after being washed up on the shore at Tunstall on the Holderness coast in 1825. A variety of feature events are held at the hall including musical events, sculpture, a classic car show and demonstrations of country house brewing and crafts. The house, the home of the Constable family for more than 700 years and still partly occupied, is now a museum owned by the Burton Constable Foundation.

Arctic Corsair
Arctic Corsair is closed from August 2019 for relocation and restoration.
Rear of Streetlife Museum of Transport, High Street, Hull
The Arctic Corsair, a sidewinder trawler, was built at Beverley Shipyard in 1960 and spent its days going to sea from Hull, where it now remains as a museum exhibit. Tours can be booked at the Museums Quarter reception at High Street in Hull on certain days. The trawler was involved in the 'Cod Wars' with Iceland in the 1970s and retired from fishing in 1987.

Rocky Mountain ISA Tree Climbing Championship has arborists compete to see who moves on to represent the region at the North American competitions. Timothy Hurst, TimHurst@Coloradoan.com

A small crowd gathered Friday around a City Park tree as a harnessed man moved nimbly among its branches.
"Slow is smooth; smooth is fast!" an onlooker called out.
The military mantra might have seemed out of place at a timed tree-climbing competition. But competitors in the International Society of Arboriculture Rocky Mountain Chapter Tree Climbing Championship say it's what the annual event is all about.
"It's a very safety-focused culture," said Bryan O'Connor, a certified arborist who traveled from Boulder to compete against 56 other climbers this weekend.
The City Park event runs through Sunday, when top climbers from the preliminary challenge round will vie for a spot at the ISA International Tree Climbing Championship. The winning man and woman will also get about $2,000 in prizes.
Some competitors are veterans with as much as 20 years of experience, head judge and certified arborist Chad Delzell said. Others have been climbing for less than a year.
Climbers are competing in five challenges designed to test their ability to safely and quickly perform work-related tree care tasks. Some of the coolest challenges are the belayed speed climb, which requires climbers to scale a roughly 63-foot tree as quickly as possible, and the aerial rescue, which requires climbers to rescue a 180-pound dummy from a tree.
You don't have to be a certified arborist to compete, but many of the competitors have earned that title. Several of them said climbing trees is just one part of being an arborist, which requires skill and physical strength but also extensive understanding of trees, soil, insects and more.
"A lot of what people see out there is a guy in a cowboy hat sawing branches off a tree," competitor Andy Reichow said. "That's not what we do. We're professionals."
Reichow is a certified arborist from Longmont who's competing in his fourth climbing competition. He's been working with trees for nine years.
One perk of the job:
"We don't work out," he said, laughing.
"We just go to work," O'Connor added.
"It's pretty sweet having an office at 70 feet," Reichow added.
If you want to watch the competition yourself, stop by City Park between 8 a.m. and 4 p.m. Saturday or 9 a.m. to 2:30 p.m. Sunday. Check out the event schedule at isarmc.org/Climber_Volunteer_Information if you want to watch.

VLAN (Virtual Local Area Network) is usually a rationally different IP sub network which enables numerous IP sites in addition to subnets to exist for the same-switched community. VLAN is a reasonable send out site which could course numerous actual physical LAN portions. This can be a modern approach directors configure changes straight into electronic local-area sites (VLANs) to boost community overall performance through splitting huge layers to send out names into smaller types.
By making use of VLAN, a community manager should be able to team in concert programs through reasonable functionality, or through apps, without having regard to actual physical place from the users. Just about every VLAN functions as being a different LAN in addition to ranges a number of changes. This will give number of gadgets to become as long as they have been for a passing community section.

Once you configure the VLAN, you are able to identify the idea to describe the principal purpose in the people with the VLAN.

Setup changes within CatOS tend to be prepared to help NVRAM once an alteration is done. As opposed, Cisco IOS Computer software doesn't preserve construction changes to help NVRAM if you don't clear this duplicate running-config. VTP buyer as well as server systems need VTP updates from other VTP servers to promptly end up saving within NVRAM without user involvement. The VTP update needs tend to be satisfied with the default CatOS operation, however the Cisco IOS update model needs a different update operation.
Due to this change, some sort of VLAN database ended up being launched in to Cisco IOS Computer software since a solution to promptly preserve VTP updates intended for VTP consumers as well as servers. In a few variants involving software program, this VLAN database is actually by means of an outside record within NVRAM, known as VLAN. You can view VTP/VLAN data that is saved within the vlan.dat and need to declare this VTP buyer or maybe VTP server when you analyze this display reputation. VTP server/client method changes don't preserve the full VTP/VLAN construction to the new venture config record within the NVRAM when you problem this duplicate running-config about these kinds of systems.
Some sort of VLAN is often a turned system that is logically segmented simply by perform, task group, or maybe program, devoid of consider to the actual locations in the consumers. VLANs have the same qualities since actual LANs, however you may class end areas regardless of whether they are not necessarily bodily situated on the same LAN message. Virtually any change dock may remain in some sort of VLAN, as well as uncast, transmitted and multicast packets are usually forwarded as well as flooded just to end areas inside the VLAN. Each VLAN is known as some sort of plausible system, as well as packets destined pertaining to areas that do not necessarily remain in the actual VLAN has to be forwarded by way of a router or maybe link since revealed throughout Physique 11-1. Just because a VLAN is known as some other plausible system, its content has a unique link Management Data Base (MIB) info and may support a unique execution connected with spanning woods. View "Configuring STP" as well as "Configuring RSTP as well as MSTP inches.
The actual Driver 3550 change sustains 1005 VLANs throughout VTP client, server, as well as translucent methods. VLANs are usually recognized having a range by 1 to help 4094. VLAN IDs 1002 by means of 1005 are usually set-aside pertaining to Expression Wedding ring as well as FDDI VLANs. VTP only learns normal-range VLANs, together with VLAN IDs 1 to help 1005; VLAN IDs in excess of 1005 are usually extended-range VLANs and are not necessarily saved inside the VLAN data source. The actual change has to be throughout VTP translucent setting whenever you produce VLAN IDs by 1006 to help 4094.
The actual change sustains per-VLAN spanning woods as well as per-VLAN fast spanning woods together with at the most 128 spanning-tree instances. One particular spanning-tree occasion is usually permitted each VLAN. Understand the "Normal-Range VLAN Setting Guidelines" part to read more regarding the quantity of spanning-tree instances as well as the quantity of VLANs. The actual change sustains both equally Inter-Switch Hyperlink (ISL) as well as IEEE 802. 1Q trunking options for giving VLAN traffic more than Ethernet ports.
A new Move in VTP Server manner will constantly engage in transmitting along with obtaining VTP and synchronizing the VTP information document regardless of edition and a new move in VTP Client manner will constantly engage in VTP information document synchronization regardless of edition. A new change in VTP v1 see through Mode will not send, obtain VTP information or maybe engage in document synchronization.
A new change in VTP v2 See-through Mode will probably send, obtain VTP information, although doesn't engage in VTP document synchronization. Really the only setting it does not cross VTP packets is really a change set up in VTPv1 See-through Mode along with VTPv3 in away from manner.
Intended for VTPv3, the variation is quite a bit better. VTPv3 offers a number of processes: server, customer, see-through along with away from. The actual variation in between see-through along with away from may be the end of contract involving acquired VTP announcements instead of relaying all of them. Together with VTP edition 3, away from manner can be set up globally or maybe on each vent (for instance trunk) starting. The actual away from manner has been recently merely readily available with Feline OS. The actual setting involving away from by using an interface will probably apply at almost all VTP circumstances.
Whenever establishing some sort of connection, the port has to be enabled in both knobs. We all will configure fa0/1 as being a shoe hyperlink in both Move A new in addition to Move W. I am accomplishing this via Cisco's packet tracer plan in a couple of Cisco 2950 knobs. Automatically just about all VLANs are allowed to end up being been given in addition to dispatched around shoe hyperlinks, this really is changed and will be reviewed afterwards.
While using the 802.1Q tunneling attribute, carrier's networks can use an individual VLAN to aid consumers who have multiple VLANs. Buyer VLAN IDs are maintained in addition to targeted visitors via unique consumers is usually segregated inside the service-provider facilities regardless if they appear to be on the same VLAN. The 802.1Q tunneling grows VLAN space by using a VLAN-in-VLAN pecking order in addition to marking the tagged packets. A new port constructed to aid 802. 1Q tunneling is named some sort of tube port. When you configure tunneling, you allocate some sort of tube port to a VLAN that may be focused on tunneling. Each and every client takes a distinct VLAN, yet in which VLAN supports every one of the consumer's VLANs.
While setting up 802. 1Q tunneling on a border move, you must employ 802.1Q trunk area locations with regard to sending out packets into your service-provider community. Even so, packets under-going the actual core from the service-provider community might be carried as a result of 802. 1Q trunks, ISL trunks, as well as non-trunking back links. While 802.1Q trunks are widely-used within these kinds of core turns, the actual local VLANs from the 802. 1Q trunks should not complement any local VLAN from the non-trunking (tunneling) slot about the same move due to the fact site visitors about the local VLAN wouldn't normally become marked about the 802.1Q sending trunk area slot.
Observe VLAN which is actually configured because local VLAN for the 802.1Q trunk area slot via ingress border move inside service-provider community (Switch 2). Move 1 regarding Buyer The communicates any marked box with VLAN 25 for the ingress canal slot regarding Move a couple of inside service-provider community, which connected to access VLAN forty. Since the gain access to VLAN from the canal slot (VLAN 40) is the same as the actual local VLAN from the border move trunk area slot (VLAN 40), the actual neighborhood label is not combined with marked packets gotten in the canal slot. The actual box holds only the actual VLAN 25 label through the service-provider community for the trunk area slot from the egress border move (Switch 3) and it is misdirected through the egress move canal slot to be able to Buyer M.
Use ISL trunks concerning core turns inside service-provider community. While client interfaces connected to border turns must be 802. 1Q trunks, we all suggest making use of ISL trunks to plug turns inside core coating.
Ensure that the local VLAN IDENTIFICATION about the border move trunk area slot is not inside the client VLAN range. As an example, if the trunk area slot holds site visitors regarding VLANs 100 to be able to two hundred, delegate the actual local VLAN many external of which range.
Pruning can be minimizing bombarded targeted visitors by uplinks - which often perform in the event of the targeted visitors can be pruned about sender area, which will be the submission coating. And so shifting this pruning towards accessibility Stratum can make good sense.
- Easier Troubleshooting: If the VLAN cannot work using a Access-Switch, you do not have in order to SSH upon a different (Distribution-) Transition to determine whether it will get pruned. However: - In the event that minimizing SPT-Instances is often a worry to suit your needs, I might recommend people look into Numerous Spanning-Tree (MST).
- Without a doubt employ VTP, recommended is to make use of its handiest as well as less hazardous feature: VTP pruning. The actual having manual pruning can be IMHO the only justification regarding making use of VTP at all (unless obviously VAN pruning can be component of one's security principle, this cannot be done with VTP pruning).

The Journey is the Destination:  The Journals of Dan Eldon,
from the jouranls of Dan Eldon, by Kathy Eldon
Hardcover, used, from our "Biographies and Memoirs" category.
The Journals of Dan Eldon
The Journey is the Destination, the Journals of Dan Eldon, is written by Kathy Eldon, based on the journals of Dan Eldon.
Hardcover, used.
Dan Eldon lived more in twenty-two years than most people do in eighty. He traveled through four continents, led expeditions across Africa, wrote a book, worked as a graphic designer in New York, made a film, and became a respected photojournalist - all before his sudden, violent death in Somalia.
As a young man of American and British parentage growing up in Africa, Dan Eldon always had an instinct for helping others. At the age of 19, aware of the plight of refugees in Malawi, he launched the Student Transport Aid, and he and his friends drove across five African countries to hand-deliver the money they'd raised to a refugee camp in the middle of a war zone. Along the way they witnessed examples of sublime beauty and extreme hardship. The trip changed the lives of everyone involved.
After graduating from high school, Dan chose to continue to travel, meeting up with a group of young journalists who shared his curiosity about the world around him, but had found a way to live it in a professional capacity. Dan traveled with them into Somalia. At the age of 21, he became the youngest photojournalist ever to work for Reuters.
An artist, Dan kept vibrant journals of his photographs and paintings, a witty commentary on the world around him.

Thirty years is old isn't old. You're still a young man. But you're not a boy, or a bro, or a manchild. The first cosmetic thing you can do to solidify this is refrain from wearing t-shirts with big logos, tour dates on the back or anything with pop cultural commentary (sorry fanboys).
You're not someone else's advertisement. No one cares what kind of statement you're making. A man's t-shirts need to be simple, made of high-quality materials and preferably plain.
Check out the geo flower pattern Matuse makes here. It's simple and has an eastern mystical motif that doesn't smack of hippy-dom. Also, this shirt is cotton yet silky soft.
Surfing blog Indoek's black boards tee is a good example of this: two surfboards criss-crossed is subtle, elegant and pleasing to the eye.
Weathered, soft and lightweight and faded. If you have time and know a good vintage store, great. But getting a new shirt that's made to look vintage is a step up, plus no one else has sweated in it. Kelly Cole and Lot Stock and Barrel have great taste and are well made. Made Worn has the rights to all of the Rolling Stones' graphics but you'll need to make an appointment because he makes his to fit perfectly and are worth the high price.
A graphic tee rests on the strength of the image being added to it. Make sure the photographer is off-the-charts good, like this one FUCT did with rock photographer, Adrian Boot, of Mick Jagger and Peter Tosh from '78.


Another powerful, tax-smart way to make a large Kingdom impact is by giving non-cash assets such as stocks. If you are interested in giving a stock gift, please call Dana Floyd directly at the National Christian Foundation, 678-892-1741.

Braby is victim of recession
Braby, manufacturer of bulk storage and process systems, has gone into administration, with 27 of its 53-strong workforce made redundant.
The Bristol-based firm, which offers ATEX-compliant silos, tanks, vessels, as well as maintenance and cleaning, was founded in 1839, but has been hit hard during the global recession. Nigel Morrison of administrator Grant Thornton said that despite having been a long-established business, and the UK market leader in its field, Braby "was not immune to the global recession, which has led to its blue-chip customer base reducing its spend on large capital items".
He said Braby's directors had been in discussions with a large European group for some time, which it hoped would provide finance into the firm to secure its future. "Unfortunately, these discussions came to an end and the directors made the difficult decision to appoint administrators."
The business is continuing to trade in the short term and with hopes to sell it as a going concern, added Morrison.

OK! I will give up on saying something very nice, just look sheepish and admit that I am one of those people who can't resist trying taters when it comes to appetizers /side dishes. Can't help it as potatoes are so versatile and I don't normally need to rush out to buy them. This month for Secret Recipe Club, I was assigned Cyndi's blog . I almost baked her coconut tart and chocolate cobbler but then I saw these delicious and easy Potato Bundles, Pioneer Woman's recipe. Yes!! Too simple for words and an easy guess, these are cubes of par-boiled potato tossed in herbs and seasoning, butter and cream ( yet another indulgent recipe from Ree Drummond!), wrapped in pieces of aluminum foil and baked in the oven till tender. Served steaming hot right in the foil, makes for an interesting appetizer / snack as well. See it as a nice fuss free accompaniment to your simple week-day meal or a delicious after school treat for your kids or for entertaining. These taste great warm and good even cold. So this could go in the school snack-box as well!
Me and kids went on a short trip to our home-town recently and I baked these potatoes on a whim late in the evening. For those travel hunger pangs which are triggered by the sight of food stalls on the platforms at the railway station, not to mention the sight of co-passengers who eat their meal in the train. Predictably, my just-fed kids were 'starving' the moment the train started to move. Since I did not want to delay their sleep time, I had to give them the snack. How I would have loved to wait for folk to open their tall dabbas filled with all sorts of delicacies before I opened my little snack. Kind of revenge you see - just to see if their noses twitch at the aroma of oregano, garlic, potatoes and butter. In case you are interested to know, I had no co-passengers with dabbas that day :(. But my kids enjoyed the potatoes thoroughly...now, who wouldn't unless its someone who hates potatoes?
Here is the very simple recipe, play around with the herbs, fresh or dried, use your choice of spices to make variations. You can find Cyndi's recipe here and Ree's recipe here I have generally adapted the recipe, so the quantities Ree uses may be different. I guess these will taste good anyway as long as the potatoes are well cooked with enough seasoning and you do not skimp too much on the butter, so feel free to alter the quantities of the ingredients. A bit too much cream and longer baking time may make the potatoes a bit too soft, but they will certainly taste good! The quantities below worked well for me and I shall be using the same again. I have omitted the onion, par-boiled the potatoes briefly and then carried on with the rest of the procedure.
Pre-heat oven to 190 degrees C / 375 degrees F. Boil the potatoes for about 3-4 minutes on high heat. Your potatoes will be fork tender, but not cooked. Drain. Cool. In a large bowl, mix together the cream, butter, garlic and the seasoning. Mix in the potatoes ensuring they are evenly coated with the cream-butter mixture. Cut pieces of aluminum foil. Place the potatoes in a single layer in the middle of the foil pieces, wrap very well (with an overlap of foil on the top), secure the ends well to make parcels. Bake for 45 minutes or till very tender. Serve in the foil. Open after about 5 minutes as there will be steam inside.
The potatoes were tender, light golden at the bottom and very tasty! Thanks to Ree Drummond and to Cyndi, this will be a recipe I shall be making again and again!
these look really good.....all the flavours are bang on...pw recipes are really good.
Thats a lovely recipe...Potatoes are a huge favourite at home !
Quite a guilt free parcels, my kids will love this.
I'm addicted to potatoes--seriously--and this is one of my favorite ways to eat them. The cream adds a decadent touch.
We LOVE potatoes like this! Great choice for your SRC post!
I can never resist potatoes! These sound perfect.
yum, these sound awesome - i'm always looking for new potato recipes so i'll have to try these soon!
Wowie, amazing it sounds :) The pictures are so so inviting !! U r awesome, Suma and thanks for sharing the recipe. I guess the 45 min cooking is also at the temp of 190'C only, right?
I love potatoes, and the only potato appetizers I've tried and loved so far are the Potato Wedges from smtc.com and a Dum Aloo (chaat specialty from Calcutta) from another blog.
Those look very very good!
@BRed - Thank you! Sorry, have not used a stand mixer, so wouldn't be able to recommend out of experience.
Those look so delicate and fresh! Cooking them today. I was looking for a potato recipe that would not need loads of sauteing or frying.Love it!
My kids love baked potatoes,will surely try this one.

I have my own form of zimmerit but it doesn't look nearly as good.
could you please post a screenshot of the dds plugin saving options they re popping up when u save the file?
The usage of an alpha channel dramatically increases the file size of the skin so it's not needed either.
But a nice and understandable tutorial Lack_26 good work.
it's very useful to save all zimmerit layers either alpha channel one or the standard one on the texture so keep your backup psd files with layers.It will be so easy to apply it to any texture you make for your tank in the future.
Great tutorial man, here's what i made with it!
How to get those tank icons next to players names?
Ok heads up for those reading this then banging head on the wall.
1.) DDS plugin ONLY works for 32bit Photoshop.
-32.32.32.32f ABGR 128 bpp | floating point <-- is all the way at bottom of first drop down.
Excellent tutorial , the same technique is used in every dds tank , i know from my experience skinning COH , although sometimes for the nrm you must also use overlay and emboss and not the nprmal map from dds plug in.
extract from stuGIII site "The 1944 batch StuG's were manufactured in either the Alkett- or the MIAG -factories. The zimmerit makes it easy to spot the manufacturer of the vehicle, with the "Waffle-pattern" zimmerit being a vehicle from Alkett and the "tile-pattern" zimmerit beeing a vehicle from MIAG."
Here you go guys i have made a panther zimmerit on GIMP with out any camos.
I can't get the Normal Map plugin to work, I've put the files in the right places and restarted Gimp many times, but still no luck. Any help?
Any chance for a Tutorial on Making and adding a raised surface Camo netting?

Klawde: Evil Alien Warlord Cat (Bk. 1) - Book Outlet
Klawde: Evil Alien Warlord Cat (Bk. 1)
by Marciano, Johnny
Klawde is not your average cat. He's an emperor from another planet, exiled to Earth. He's cruel. He's cunning. He's brilliant... and he's about to become Raj Banerjee's best friend. Whether he likes it or not.
Klawde had everything. Sharp claws. Fine fur. And, being the High Commander of the planet Lyttyrboks, an entire world of warlike cats at his command. But when he is stripped of his feline throne, he is sentenced to the worst possible punishment: exile to a small planet in a quiet corner of the universe... named Earth.
Raj had everything. A cool apartment in Brooklyn. Three friends who lived in his building. And pizza and comics within walking distance. But when his mom gets a job in Elba, Oregon, and he is forced to move, all of that changes. It's now the beginning of summer, he has no friends, and because of his mother's urgings, he has joined a nature camp.
It's only when his doorbell rings and he meets a furball of a cat that Raj begins to think maybe his luck is turning around...
Heavily illustrated, with a hilarious, biting voice that switches between Raj and Klawde's perspectives, this is the story of an unlikely friendship that emerges as two fish out of water begin to find their footing in strange new worlds.

I mentioned that conversation to Rhonda last November while she was here to help scatter Dave's ashes on Cape Canaveral beach.
After returning to Florida late Sunday night following a two-week Christmas holiday in North Carolina, the first thing I did yesterday was fetch the huge box from the post office.
After carefully unpacking it from buckets of foam popcorn and yards of bubble wrap, I rearranged my living room to accommodate Dave's clock (spent all afternoon cleaning and moving furniture!!!) and though I was exhausted afterward, I stepped back to admire it, excited to incorporate Dave's "heartbeat" into my home.
The clock is ticking — the heartbeat of a house, as Dave once described it — and the chimes on the half hours are a delight to hear — almost heavenly!
He lives on with every beat.
I can see him smiling… lovely.
Beautiful story, Andrea. Pinko, Fur and I had a great old pal pass away on the same day Dave did. Heaven got a little livelier in early August.
