\section{Introduction}

Anisotropic molecules forming thermotropic and lyotropic liquid crystals
can exhibit tilt. The onset of tilt is the characteristic of the
smectic A-smectic C phase transition\cite{LC}. Tilted phases are observed
in monolayers formed by amphiphilic molecules\cite{Amp}.
A variety of tilting phase transitions are possible at solid-fluid
interfaces incorporating anisotropic molecules\cite{TLC}-\cite{li}.
Diverse molecular mechanisms can give rise to such phase transitions.
In the following, we propose a novel mechanism for the development of tilt at
surfaces carrying grafted rods. In particular, we consider a flat solid
surface supporting covalently bound rodlike molecules at a surface density
$\rho < 1$.
The rods are grafted to the surface so that isolated rods are
oriented along the surface normal. The grafting functionality, the ``joint",
is assumed to allow bending at the price of an elastic energy penalty.
A tilting phase transition is predicted to occur as the grafting density
$\rho$ increases. The tilt is favoured by the van-der-Waals attraction
between the rods, but is opposed by the bending penalty.
The interplay between these two energies gives rise to a tilting phase
transition. The transition is predicted at zero temperature. However,
the mechanism still works at sufficiently low finite temperatures,
as we shall argue in the discussion.

From a fundamental perspective, this mechanism is of interest as a complement
to the variety of tilting mechanisms studied in the literature.
Tilting transitions are also of importance vor the design of alignment
layers for liquid crystal displays\cite{LCD}. The orientation of the nematic
director inside a liquid crystal cell with no electric or magnetic field
applied is usually determined by the interface. Properly designed interfaces
supply the desired in-plane asymmetry as well as a certain "pretilt" angle.
Grafted liquid crystal (LC) layers may form good
alignment layers, when the LC-director adopts the tilt of the grafted layer.
In practice, the tilt of the nematic director may not be equal to the tilt
of the grafted layer due to the complicated interaction between the
nematic medium and the layer. This does not however detract from the
practical potential of this system. A tilting phase transition
driven by the grafting density may provide a scheme to fabricate
alignment layers with an arbitrary tilt angle.

Another aspect of grafted layers of interest to
liquid crystal alignment is their behavior under nematic
orientational stress. Such stresses occur during the Frederiks transition and
are of high practical importance as well. Coupling between the tilting phase
transition and the Frederiks transition is expected to reduce the switching
voltage of such devices\cite{TLC}.

There are a number of reports, where rods have been covalently attached to
a surface \cite{bue,sek,kno}. In most cases, however, the joint is assumed
to be so flexible that it will not show any resistance to bending. Recently,
attachment with rigid joints has been claimed as well\cite{whi,mac}. Note
however, that a rigid joint does not necessarily imply perpendicular
orientation. The angle of the joint will depend on details of the chemistry.
Right-angled joints are the exception rather than the rule. If, however,
the tilt angle is small and the in-plane direction of tilt is random,
it is reasonable to describe the rods as perpendicularly oriented.

The essential physics involved is discussed in section II for a highly
simplified case: A linear array of grafted rods. An analysis of the two
dimensional case is presented in section III. A comparison to previously
discussed tilting phase transitions is given in the discussion.

\section{The Linear Array}

The underlying physics of the tilting transition are most easily understood
in the case of a linear array. The rods, of length $L$ and diameter $a$, are
grafted onto a straight line at regular intervals of width $D$. In the
absence of rod-rod interactions, the grafting functionality imposes
perpendicular orientation of the rods, {\em i.e.} the angle between the rods
and the surface normal is $\gamma =0$. However, the joint can be deformed
with a bending elastic penalty of
\begin{equation}
\label{II1}
U_{bend} =\sum_{i=1}^{\infty} A_{i}{\sin}^{2i} \gamma,
\end{equation}
where $A_{i}$ are non negative phenomenological constants specified in units
of energy. The rods also experience mutual van-der-Waals attraction. We
picture the rods as comprising monomers of size $a$\cite{JNI}. The non
retarded van-der-Waals attraction between two monomers separated by a
distance $r$ is
\begin{equation}
w=-c/r^6,
\end{equation}
where $c$ is a material constant with units of ${\rm [energy][length]^6}$.
The van-der-Waals attraction between two parallel rods, $E(D,\gamma)$, may
be obtained by integration of the pairwise interactions between monomers
belonging to the different rods (see Appendix A). At $D/L < 1$, the leading
terms in $E(D,\gamma)$ are
\begin{equation}
\label{II3}
 E(D, \gamma) = - \frac{K}{(d \cos \gamma)^5} \{
\frac{3 \pi}{2} + d \cos \gamma (\cos^2 \gamma - 3 - 3 \gamma \tan \gamma)
+ {\cal O}(d^5) \}
\end{equation}
with $d=D/L$ and $K = c/(4 a^2 L^4)$.
Note that $E(D,\gamma)$ favors large tilts since in this limit the reduced
distance between the rods is $D \cos \gamma < D$. Notice further that
$E(D, \gamma)$ diverges at $\gamma = \pi/2$, when the rods
are fully tilted. This last feature is however an artefact, since
$\gamma = \pi/2$ is actually unattainable because of excluded volume
interactions between the rods. An upper bound for the maximal possible tilt
in the $D/L < 1$ case is ${\gamma}_{up} = \arccos (a/D)$.

To analyze the phase behaviour, it is convenient to consider $E(D, \gamma)$
in the limit of $d \ll 1$ and $\gamma \ll 1$. In this limit, where
corrections due to the finite length of the rods are negligible, the
leading terms in the expansion of of $E(D, \gamma)$ in powers of
${\sin \gamma}^2$ are
\begin{equation}
\label{II4}
E(D, \gamma) = -(3 \pi K/2d^5)[1 + (5/2){\sin}^2 \gamma +
(35/8){\sin}^4\gamma+ \cdots] =-\sum_{i=1}^{\infty}B_i {\sin}^{2i}\gamma.
\end{equation}
We now consider the total van-der-Waals energy, $U_{vdW}$,
of a rod in a uniformly tilted array. To obtain $U_{vdW}$ we sum the pairwise
interactions of the rod {\em i.e.}
$U_{vdW}=2\sum_{n=1}^{\infty} E(nD, \gamma)$. In the limit of $D/L \ll 1$,
when all terms in $E(D, \gamma)$ exhibit a $D^{-5}$ dependence, the result is
\begin{equation}
\label{vdw}
U_{vdW} = 2 \zeta(5) E(D, \gamma),
\end{equation}
where $\zeta(5) = \sum _{i=1}^{\infty} k^{-5} \approx 1.037$ is the
appropriate Riemann zeta function. In doing so, we assume that the van der
Waals interactions are additive. That is the case when the dielectric
susceptibility of the materials is an additive function of the constituting
components {\em i.e.} when the susceptibility is proportional to the
concentration of the rods\cite{Add}. One should however note that this
requirement in not always fulfilled\cite{NAd}. If one considers as an
approximation only nearest neighbour interactions, the calculated
interaction energy $U_{vdW} = 2 E(D,\gamma)$ is very close to
(\ref{vdw}). Hence the total van der Waals energy is dominated by the
nearest neighbour contributions.

The behaviour of the linear array of rods is determined by the total energy
per rod $U=U_{bend}+U_{vdW}$. It is instructive to consider the behaviour of
$U$ in a number of scenarios. If one overlooks the excluded volume effect
between the rods, $U_{vdW}$ diverges at $\gamma =\pi/2$. When  $U_{bend}$
is finite at $\gamma = \pi/2$, this divergence dominates the behaviour of $U$,
$U(\gamma=\pi/2)=-\infty$, indicating that all the rods are tilted.
While $U(\gamma)$ may exhibit two minima, $U(\pi/2)=-\infty$ always
corresponds to the equilibrium state in this scenario. A richer repertoire
is possible when the bending penalty at $\gamma=\pi/2$
is infinite as well. In that case, all terms in the expansion of $U_{bend}$
have to be retained. Consider, for example, the situation when the
coefficients of ${\sin}^{2i}\gamma$ of $U_{bend}$ and $U_{vdW}$ are such that
$A_i-B_i>0$ for all $i \ge 2$. A second order tilting phase
transition is expected when $A_1-B_1=0$ {\em i.e.} $A_1/K=15\pi/4d^5$ with
$d=D/L$ or $d=d_c=(15\pi K/4A_1)^{1/5}$. The rods are perpendicular to the
surface, $\gamma=0$, when $d>d_c$, while for $d<d_c$ they are tilted at
angle of $\gamma \propto \sqrt{d_c-d}$. A first order phase transition is
expected at $A_1-B_1>0$, if some of the higher order terms are
negative and large enough such that
$\sum_{i \ge 2} (A_i-B_i) \sin^{2i}\gamma <0$
for some value of $\gamma < \gamma_{up}$.

The role of higher order terms of $U_{bend}$ is certainly important.
A discussion based on this effect suffers however from two disadvantages.
Typically, the higher order $A_i$'s are unknown. Also, a chemical design
allowing for control of these parameters is impractical.
To simplify the analysis, we assume that the bending energy is Hookean
up to a cutoff angle $\gamma_{up}$. For specifity, we assume that it is
the result of excluded volume interactions and hence given by
$\gamma_{up} = \arccos (a/D)$ as noted earlier. Note however $\gamma_{up}$
may also be imposed by the bending potential.

It is helpful to consider first $U$ in the limit of $d \ll 1$ and
$\gamma \ll 1$, retaining only the first order terms of $U_{vdW}$ and
$U_{bend}$ as specified by (\ref{II1}) and (\ref{II4}). $U$ is then given by
\begin{equation}
U=[A_1-15\pi K\zeta(5)/2d^5]{\sin}^2 \gamma.
\end{equation}
When $\epsilon =A_1-15\pi K\zeta(5)/2d^5>0$, the system may exhibit a first
order tilting phase transition. We shall discuss this scenario in greater
detail shortly. A second order transition is expected when $\epsilon=0$,
while if $\epsilon < 0$ the system will be tilted. To analyze the first
order transition, it is helpful to express $U$ in terms of (\ref{II1}) and
(\ref{II3}). The energy per rod in the limit of $d \ll 1$ is then
\begin{equation}
U = A_1 {\sin}^2\gamma - \alpha/(d^5 {\cos}^5 \gamma),
\end{equation}
where $\alpha = 3 \pi \zeta(5) K$ and $\gamma$ is allowed to vary
between $0$ and${\gamma}_{up}$. $U$ is minimal at $\gamma =0$, where
$U(0)=-\alpha/d^5$, and at ${\gamma}_{up}$, where
$U(\gamma_{up})=A_1{\sin}^2 {\gamma}_{up}-\alpha/(d^5{\cos}^5{\gamma}_{up})$.
It is maximal at $0<{\gamma}_{max}<{\gamma}_{up}$, defined by
${\cos}^7{\gamma}_{max} =5\alpha/2A_1 d^5$.
A first order phase transition between an untilted phase and a phase tilted
at an angle ${\gamma}_{up}$ occurs when $U(0) = U({\gamma}_{up}) $ or
$\alpha/d^5 A_1 = {\sin}^2{\gamma}_{up}/({\cos}^{-5}{\gamma}_{up}-1)$.

\section{The Planar Case}

To extend our considerations to two dimensional, planar arrays, it is
necessary to allow for two geometrical effects. First, for a given rod the
number of interacting neighbors increases with the distance. Thus, a shell
of radius $r$ and thickness $dr$ contains $\rho r dr$ interacting rods, while
in the linear array the number is always $\rho dr$. Second, in the two
dimensional case the shortest distance between parallel rods, $\delta$,
varies with azimuthal angle, $\phi$, between the vector joining the grafting
sites and the direction of the tilt. When $\phi=0$ the shortest distance
is $\delta=r\cos \gamma$ while for $\phi = \pi/2$ it is $\delta=r$. In general,
$\delta$ is given by $\delta = r(1-{\cos}^2\phi {\sin}^2 \gamma)^{1/2}$
(Figure 1). In realistic situations, it is also necessary to allow for the
randomness of the grafting sites. These are unlikely to form a regular
lattice. It is thus useful to characterize the array of grafting sites by a
pair distribution function
\begin{equation}
g(r) = \rho h(r).
\end{equation}
The introduction of $g(r)$ also simplifies the mathematical treatment of
the problem. The van-der-Waals interaction energy per rod in a uniformly
tilted array is
\begin{equation}
\label{av}
U_{vdW}=\rho \int_0^{\infty} rdr \int_0^{2 \pi}d \phi h(r) V(r,\phi,\gamma),
\end{equation} where $V(r, \phi,\gamma)=E(r, \theta)$ and $\theta$ is
defined by $\sin \theta = \sin \gamma \cos \phi$. It is then possible to
specify $U_{vdW}$ in terms of the inverse moments of $h(r)$
\begin{equation}
\label{utot1}
{\mu}_3 = \int_0^L h(r)dr/r^3 \qquad \qquad {\mu}_4 = \int_0^L h(r)dr/r^4,
\end{equation}
leading to
\begin{equation}
\label{utot2}
U_{vdW}(\rho,\gamma) =
-\frac{\rho c \pi}{ a^2} \mu_3
[{}_2F_1(\frac{1}{2},\frac{5}{2},1,\sin^2 \gamma) \frac{\pi}{2} l
- \frac{1}{\cos^4 \gamma}] + {\cal R}(\gamma)
\end{equation}
with the hypergeometric function
${}_2F_1(1/2,5/2,\sin^2\gamma) =
\int_0^{\pi/2} d \phi [1-\sin^2 \gamma \cos^2 \phi]^{-5/2}$
and $l=L (3\mu_4)/(2 \mu_3)$.
The remainder ${\cal R}$ is of order $1/L^2$ (see Appendix B).

For simplicity, we take $h(r)$ to be a simple step function
\begin{equation}
h(r) = \Theta(r - D)
\end{equation}
with the minimal distance between rods $D$. At $D \ll L$, the inverse moments
$\mu_i$ are then given by $\mu_i = 1/((i-1)D^{i-1})$ and $l = L/D$.
We further assume that the minimal distance between rods depends on
the grafting density according to a proportionality law
$\rho = \nu/D^2$. This implies that the rod grafting sites are distributed
evenly on the plane, like in the case of the linear array discussed in
section 2, where the distance between rods is kept fixed.
The van-der-Waals energy can then again be expanded
in powers of $\sin \gamma$.
\begin{equation}
\label{vdwexp}
U_{vdW}(\rho,\gamma) =
- \tilde{K} L \sqrt{\rho}^5 \{1 + (5/4)\sin^2 \gamma + (105/64) \sin^4 \gamma
+ \cdots \} = - \sum_i \tilde{B}_i \sin^{2i} \gamma
\end{equation}
with $\tilde{K} = c \pi/(4 a^2 \sqrt{\nu}^3)$.
After combining this expression with the bending energy per rod
(\ref{II1}), one can follow the discussion from the previous
section: A second order transition is expected at $A_1 = \tilde{B_1}$,
{\em i.e.} at the critical density
\begin{equation}
\rho = \rho_c = (\frac{4 A_1}{5 \tilde{K}})^{2/5} \cdot L^{-2/5}.
\end{equation}
It may be preempted at some lower density by a first order tilt transition,
if the cutoff angle $\gamma_{up}$ is large enough such that
\mbox{$U_{vdW}(\rho_c,\gamma_{up})-U_{vdW}(\rho_c,0)+U_{bend}(\gamma_{up})=0$}.
The van der Waals energy in the limit $D/L \ll 1$ scales
like $L \sqrt{\rho}^5$, whereas the bending energy per rod is independent
of rod length and grafting density. Hence the densities, at which
phase transitions occur, scale with the rod length $L$ like
$\rho_c \propto L^{-2/5}$.

We note that these considerations only hold under the
supposition that the rods are distributed evenly on the plane,
$D \propto 1/\sqrt{\rho}$, as mentioned above. If the
rods are grafted independently of each other, a Poisson distribution
is expected. In this case, the assumption $D=a$ with the monomer size $a$
may be more appropriate. Eqn (\ref{vdwexp}) then
has to be replaced by
\begin{equation}
U_{vdW}(\rho,\gamma) =
- \frac{c \pi}{4 a^5} \rho L
\{1 + (5/4)\sin^2 \gamma + (105/64) \sin^4 \gamma + \cdots \}
\end{equation}
and densities of phase transitions scale with the rod length as
$\rho_c \propto 1/L$. A second order phase transition is expected at
$\rho_c = (16 a^5 A_1)/(5 \pi c L)$. However, in this case, the validity
of a mean field averaging as performed in eqn (\ref{av}) becomes
questionable. This is because domains with different tilt order and
local defects of the tilt order parameter may become important even at
zero temperature.

\section{Discussion}

The tilting behaviour considered in this paper results from the interplay
between three factors: The van-der-Waals attraction between the rods, the
bending elasticity of the joint and the grafting constraints. Clearly no
joint is perfectly rigid. The necessary grafting constraints involve two
ingredients:
(i) The bonding of the rods' ends to a flat surface in a manner imposing
perpendicular orientation of the non interacting rods.
(ii) The absence of lateral mobility.
The rods start to tilt at the minimal grafting density $\rho_c$, where the
effect of the attractive interaction starts to overcome the bending penalty.
Upon further increasing the grafting density, the excluded volume
interactions between rods gain importance. As the rods are pushed together,
they gradually stand up and finally undergo another continuous transition
to an untilted state at $a=D$, where $\gamma_{up} = \arccos (a/D) = 0$.
This second transition is driven by the interplay between attractive and
repulsive interaction. Thus one expects tilt order in a well-defined density
regime (Figure 2).

We should note that, at zero temperature, there is no entropic opposition
to the in plane symmetry breaking associated with collective tilt. At
finite temperatures, however, the entropy comes into play, giving
rise to a variety of new phenomena:

First, it is well known that Goldstone excitations will destroy any
true long range order in two dimensional systems with continuous
symmetry, where the ground state is continuously degenerated\cite{mw}.
In our case, the Goldstone modes are long wavelength fluctuations
of the in plane tilt direction.
At sufficiently low temperatures, however, one still has quasi long
range order, {\em i.e.} the correlation functions decay algebraically.
Unless preempted by a first order transition, Kosterlitz-Thouless-type
unbinding of vortex excitations is expected to destroy this order at high
temperatures. Note that the energy contained in the vortices will
approach zero as the tilt goes to zero. Therefore systems with a small
tilt will undergo a Kosterlitz-Thouless transition at lower temperatures than
systems with high tilt. This implies that the tilting phase behaviour at
finite, sufficiently low, temperatures is very similar to the zero
temperature behaviour -- but with two differences: (i) the tilted state now
has quasi long range order rather than true long range order, and (ii)
the second order tilting transitions are replaced by Kosterlitz Thouless
transitions.

Second, the entropy being another factor which opposes collective tilt,
it may assume the role of the bending elasticity at
finite temperatures. Indeed, the competition of attractive interactions
between rods and rod orientational entropy gives rise to a scenario of
tilting transitions which is very similar to the one discussed
here\cite{wang,tilt}. The details may be different because the entropy
will depend on the lateral density due to the packing constraints, whereas the
bending elasticity is independent of lateral density.

When lateral mobility is allowed, phase separation will replace the tilting
phase transition (cf. \cite{li,l1}), because the surface
free energy of untilted rods is higher than that of tilted rods.
Note however that this last scenario can be modified by several factors.
First, if the rods are given some flexibility, the loss of surface free energy
per chain upon lowering the chain density is compensated in part by
the gain of conformational entropy. As a consequence, phase
separation occurs at lower surface densities. Self consistent field
calculations show that, for sufficiently flexible chains, the areal density
of the condensed phase may be low enough to favour tilt\cite{l2}.
Second, the phase separated condensed phase may support tilt even in systems
of perfectly stiff rods if this is energetically rewarded, e.g. by attractive
chain-surface interactions\cite{wang,chen,Ahalperin,rice}.
Third, the distance of closest approach between grafting sites may be larger
than $a$, the rod diameter. This last situation is reminiscent of the onset of
tilt in amphiphilic monolayers, when the distance between ``grafting sites" is
determined by the effective radius of the ionic head group\cite{shih}.
A similar mechanism \cite{RC} for the development of tilt has been proposed
for lamellae formed by rod-coil diblock copolymers {\em i.e.} polymers
consisting of a rod like block joined to a flexible, coil like block. These
can form lamellae in a selective solvent which is a precipitant for the rods.
In this case the surface free energy of the close packed rods opposes the
tilt which is favoured by the repulsive interactions between the overlapping
coils. These last tilt mechanisms are however less closely related to our
system since they do not involve rods grafted to a surface with $\rho <1$.
The rods are always closely packed. Furthermore, the driving force for the
tilt comes from units outside the rods (substrate, head groups and flexible
blocks respectively) and will not operate in a system consisting solely of
rods.

As discussed in the introduction, tilting transitions are particularly
important, from a technical point of view, in relation to liquid crystal
alignment. If the surface
is in contact with a nematic liquid crystal, the tilt of the rods at
the surface will influence the director in the bulk of the liquid crystal,
and vice versa.  Tilt transitions such as the one discussed here will then
translate into ``anchoring transitions'', which involve changes of the
direction of alignment in the bulk of the liquid crystal.

In this context, it is instructive to briefly discuss the tilting phase
transition predicted for liquid crystalline polymers (LCPs) grafted
onto a flat surface immersed in a good nematic solvent\cite{TLC}.
In this case the tilt results from the interplay between the repulsive
monomer-monomer interactions and the elasticity of the solvent.
This situation involves a number of distinct features.
First, the effect is expected in the case of long, main chain LCPs supporting
a number of hairpin defects. Such LCPs adopt a highly anisotropic, ellipsoidal
form such that their major axis is aligned with the nematic director.
Second, the effect depends on the anchoring conditions imposed by the
grafting surface. It is predicted when the anchoring is homogeneous {\em i.e.}
the nematic director at the interface is parallel to the surface. As a result
of the coupling between the LCPs and the nematic solvent, the orientation of
the isolated LCPs is with their major axis parallel to the surface.
As the grafting density increases, the overlap between the LCPs grows.
This, in turn, results in an increase of the repulsive interactions between
the LCPs. These can be weakened by tilting the LCPs thus decreasing the
monomer volume fraction within the layer. The onset of tilt is however
opposed by the elasticity of the nematic solvent since it results in a
distortion of the nematic medium. The interplay of these two contributions
gives rise to a second order tilting phase transition. Tilt is
now favoured by repulsive interactions rather than by attraction. The
role of the joint is assumed by the nematic solvent. The coupling between
the LCP and the oriented nematic determines the orientation of the isolated
LCPs and gives rise to the elastic penalty that opposes tilt.

As compared to the case studied in the paper and the tilting transitions
discussed so far, the last scenario is different in that the tilting
transition does not involve in-plane symmetry breaking. The azimuthal
symmetry is already broken in the ``untilted'' state, in which the
LCPs lie parallel to the surface. This is an effect of the nematic
medium, which insures collective alignment even at the absence of
direct interaction between the molecules. Such tilting transitions
without symmetry breaking are frequently found in liquid crystal systems.

An experimental example are anchoring transitions induced by
trans-cis isomerizations of azobenzene molecules, which are covalently attached
to the surface\cite{bue,sek,kno} and immersed in a nematic LC solvent. In these
cases, the rods are attached to the surface via flexible spacers comprising
4-10 CH${}_2$-units. UV--irradiation induces a transition from a rod like
trans conformation to a highly bent cis conformation in the azobenzene
molecules. The rods in the trans state favour perpendicular (homeotropic)
alignment of the liquid crystal molecules, whereas the substrate and the
molecules in the cis state favour parallel (homogeneous) alignment. At a
high density of trans units, the competition of these two factors leads to
tilted anchoring. UV--irradiation causes the density of trans units to
decrease, thereby inducing a continuous transition to an untilted state with
parallel anchoring\cite{bue}.

\section{Conclusions}
We have described a tilting transition in grafted layers of rigid rods attached
to the surface via a chemical bond, which resists bending. The competition
between bending elasticity on the one hand and van der Waals attraction on
the other hand drives the transition. The transition can be of first or
second order. We find perpendicular alignment for low coverage, and tilted
alignment for higher densities. Second order transitions will be preempted
by Kosterlitz-Thouless transitions at nonzero temperatures. We compare the
transition with a number of related tilting transitions, which have been
discussed in the context of monolayers and of liquid crystal alignment.
In some cases similar scenarios are found, where the entropy takes the role
of the stiff chemical bond.

\section*{Appendix A: The one dimensional case}

We consider two parallel rods of length $L$ grafted at distance
$D$ from each other, and uniformly tilted by an angle $\gamma$. The sum
of van der Waals interactions between monomers from
different rods is then given by
\begin{equation}
E(D,\gamma) = - (c/a^2) \int_0^L dx \int_0^L dx'
\frac{1}{[(D \cos \gamma)^2 + (x-x'+D \sin \gamma)^2]^3} .
\end{equation}
We can decompose the integral and rewrite $E(D,\gamma)$ as
\mbox{$E = - c/(4 a^2 L) \cdot \widehat{E}(D/L,\gamma)$} with
\begin{eqnarray*}
\lefteqn{\widehat{E}(d,\gamma) = 8[\int_0^1 dx \frac{1-x}{(\delta^2+x^2)^3}}\\
&&- \int_0^\varepsilon dx (\varepsilon-x) \Big[ \frac{1}{(\delta^2+x^2)^3}
-\frac{1/2}{(\delta^2+(1+x)^2)^3}-\frac{1/2}{(\delta^2+(1-x)^2)^3} \Big],
\end{eqnarray*}
where $\delta = d \cos \gamma$ and $\varepsilon = d \sin \gamma$.
The integrals can be solved exactly, and one obtains
\begin{eqnarray}
\lefteqn{\widehat{E}(d,\gamma) = \frac{1}{(d \cos \gamma)^4} \Big\{
\cos^2 \gamma - 3 \gamma \tan \gamma -
\frac{d^2 \cos^2 \gamma (1+d^2)}{(1+d^2)^2 - 4 d^2 \sin^2 \gamma}}\\
&&+ \frac{3}{2} \Big[
(\frac{1+d \sin \gamma}{d \cos \gamma})
\arctan (\frac{1+d \sin \gamma}{d \cos \gamma})
+ (\frac{1-d \sin \gamma}{d \cos \gamma})
\arctan (\frac{1-d \sin \gamma}{d \cos \gamma}) \Big] \Big\}.\nonumber
\end{eqnarray}
This function can be expanded in different ways for the cases
$d < 1$ and $d > 1$:

\noindent
(a) $d < 1$:
\begin{equation}
\label{e1}
\widehat{E}(d,\gamma) = \frac{1}{(d \cos \gamma)^4}
\Big\{\frac{3 \pi}{2 d \cos \gamma} + \cos^2 \gamma
- 3 - 3 \gamma \tan \gamma \Big\}
+ {\cal R}_1(d,\gamma)
\end{equation}
with
${\cal R}_1(d,\gamma) = 2/5 + d^2(4 - 32/7 \cdot \cos^2 \gamma)
+ {\cal O}(d^4)$

\noindent
(b) $d > 1$:
\begin{equation}
\widehat{E}(d,\gamma) = \frac{4}{d^6} + \frac{1}{d^8}(14-16 \cos^2 \gamma)
+ {\cal O}(\frac{1}{d^{10}}) \equiv {\cal R}_2(d,\gamma)
\end{equation}

\section*{Appendix B: The planar case}

More generally, let the two rods be grafted on the $xy$-plane and
uniformly tilted in the $y$-direction. The vector connecting their grafting
points can be parametrized as \mbox{$\vec{r}=r (\cos \phi, \sin \phi,0)$}
and the tilt vector is $(\sin \gamma, 0,\cos \gamma)$. The interaction between
the two rods is then $V(r,\phi; \gamma) = E(r,\theta)$ with an effective
tilt angle $\theta$ determined by $r \sin \theta = \vec{r} \vec{t}$
(see Figure 2).
We now consider an assembly of rods, which are randomly distributed on the
plane according to an isotropic pair distribution function
$g(r) = \rho h(r)$. The total van der Waals energy per rod,
given by eqn (\ref{utot1}), can then be calculated explicitly for
the leading terms in the expansion (\ref{e1}). Using the identities
\begin{displaymath}
\int_0^{\pi/2} \frac{d \phi}{\sqrt{1-z^2}^5} = \frac{\pi}{2}
{}_2F_1(\frac{1}{2},\frac{5}{2},1,\sin^4 \gamma),
\end{displaymath}
with $z = \sin \gamma \cos \phi$, and
\begin{displaymath}
\int_0^{\pi/2} d \phi \Big[
\frac{3 z \arcsin z}{\sqrt{1-z^2}^5} + \frac{z^2+2}{(1-z^2)^2} \Big]
= \frac{\pi}{\cos^4 \theta},
\end{displaymath}
one obtains eqn (\ref{utot2}).
The order of magnitude of the neglected rest ${\cal R}$ can be estimated by
\begin{eqnarray*}
\frac{4 a^2 L^2}{\rho c} {\cal R} &=&
\int_0^{2 \pi} d \phi \: \{ \int _0^1 dx \: x \: h(x L) {\cal R}_1(x,\theta) +
\int _1^{\infty} dx \: x \:  h(x L) {\cal R}_2(x,\theta) \} \\
& \le &
2 \pi h_{max} \{ \int_0^1 dx \: x \: (2/5+4 x^2 + \cdots)
+ \int_1^{\infty} dx \: x \: (4/x^6 + 14/x^8 + \cdots) \} \\
&=& {\cal O}(1),
\end{eqnarray*}
hence ${\cal R}$ is of order $1/L^2$.

Q: How to attach a Laravel blade view in mail I'm trying to attach a blade view when send mail. I'm using Laravel 4. I tried with this:
Mail::send(
    "emails.clientEmail",
    $data,
    function($message) use ($data,$template,$subject) {
        $message->to($data['email'], $data['name'])
            ->from($template['from'],$template['from_name'])
            ->subject($subject)
            ->attach(app_path().'/views/email.blade.php');
    }
);

But my view email.blade.php is in blade template and it doesn't display the html but code.
How should I send it and display as html?

A: As you metioned you can use attachData and add rendered data like:
$renderedData = view('email')->render();

Mail::send(
        "emails.clientEail",
        $data,
        function($message) use ($data,$template,$subject) {
            $message->to($data['email'], $data['name'])
                ->from($template['from'],$template['from_name'])
                ->subject($subject)
                ->attachData($renderedData, 'name_of_attachment');
        }
    );

In this system I have explained him each and every steps and he followed all steps. I always wanted to make a tutorial on how to get started with google code hosting but now I have spent 2-3 hour teaching on chat to produce "quick start chat". You can also blog such "quick start chat" as tutorial.

11:25 AM Abhishek: Sourceforge.net seems good...But, I need to upload the Source in zip or rar or .tar format instead of erm...open editing version like GIT or SVN?
Abhishek: I have created the project...Checkout?
Abhishek: Ohh..Okay, I am logging into sourceforge...I'll see what I can do, thanks;) Did you read The Lost Symbol by Dan Brown or Code to Zero by Ken Follet?
Do you have svn installed ??
do you have google wave account ?
11:33 AM Abhishek: No..but I have already created a project..whats google wave?
11:44 AM Abhishek: now. it says CHECKED OUT REVISION 1...wait... svn checkout https://imperius.googlecode.com/svn/trunk/ imperius --username hackerboymayabhi ...DO you need the password?

Mark Cuban: Technology Is the Solution to Terrorism and Illegal Immigration in the U.S.
The billionaire investor explains how innovative technologies could start changing the national security landscape.
By Helena Ball@helemball
Mark Cuban.
In the wake of yet another deadly terrorist attack, on Tuesday at Turkey's biggest airport, Mark Cuban is demanding action.
The billionaire businessman, appearing on Megyn Kelly's Fox Business show the same night, called for both presumptive presidential candidates to do more than just say "This is bad."
Cuban proposed that the country look to technological innovations for a solution. Among other ideas, he would turn to automation and robotics.
"How do you deal with immigration? How do you deal with radical Islamic terrorists trying to come into the country? You're going to need to use tech," said Cuban, in a Bloomberg interview earlier this week.
Both the Republican and Democrat would-be nominees are technologically illiterate, he said to Bloomberg's Cory Johnson, which is the reason they are blind to technological solutions to the country's biggest issues.
"I am a tech guy," Cuban continued, "I've invested in companies that allow for, and create the ability to test and evaluate people before they come in." The billionaire explained that he has invested in artificial intelligence firm Converus, whose lie-detecting technology can tell with 85 percent accuracy whether or not you'll be a threat to national security.
The technology's high level of accuracy is possible because it takes out the human error of conventional polygraphs, according to Converus CEO Todd Mickelsen. And the degree of confidence can increase to more than 98 percent when combined with a secondary method, he adds.
"There are tools available for vetting terrorists that are not being taken advantage of," Mickelsen tells Inc. "Why not apply a different technological solution?" The tool might be particularly useful in cases involving refugees or other situations where little background data is available, the tech CEO says. "Why not leverage the best database available--the human mind of the individual--and ask them the same questions you're asking them anyway but on a computer?"
Cuban is convinced that Converus's EyeDetect, which allows for optical scanning, would be instrumental for immigration and as a potential terror warning system. Earlier this month, Cuban tweeted about use of the tool to identify possible terrorist suspects among Syrian refugees:
Tech to slow terror - A Startup Wants to Use Eye Tracking to Detect If Syrian Refugees Are Terrorists https://t.co/hMOzRZLH4b
-- Mark Cuban (@mcuban) June 18, 2016
And later, he posed the question:
How do we screen #police, #military & #SecurityGuards for #terrorist ties? https://t.co/EbpdYslvH0 pic.twitter.com/hHRLNaTHTh
-- Converus Inc. (@ConverusInc) June 20, 2016
Cuban has also previously stated his support for legal immigration and open, international competition for talent. In an interview with Fox Business last fall, he said: "When it comes to high-end jobs, the competition from overseas for jobs makes us stronger."
It is a position that puts him at odds with presumptive Republican nominee Donald Trump. The presidential candidate proposes protecting American businesses and jobs against foreign competition through measures such as increasing the wage requirements for H-1B work visa holders (in addition to his now infamous huge wall).
But Cuban holds that isolation is not an alternative. "Voting for 'no' is never a solution for much of anything," he said Tuesday, explaining that, as shown by the Brexit vote, it usually leads to confusion and uncertainty. "Confusion and uncertainty is always bad for business and is always bad for markets."

Videos are great, but how long would it take to make one? Believe it or not, you actually have a lot to do with the length of video production time. We cover that here in Video Answers Episode 14.
Like the question of cost, how long it takes to make a video depends on you and details of your video.
What do I mean when I say it depends on you?
You play a key role in the success of your project. In fact, here are five ways you can keep your video production on schedule.
Input is good, but it can be time consuming and confusing to get feedback and direction from multiple sources – especially when they're conflicting. So before you're project gets started, designate a single point of contact within your organization for the project.
Think of video production as a pyramid where each layer is built on the previous. A hold up anywhere in the process can create ripple effects everywhere. That's why we ask our clients to be ready to promptly approve and provide all requested materials.
We do everything we can to keep you in the loop before, during and after your production. But if you have questions, or just need some clarity, by all means verify, clarify, and ask to keep your project moving along.
Communication is a two-way street. So, in the same way we communicate to you we also need the same level of communication from you. If your logo changes in the middle of the project or it's looking like we won't be able to shoot in the Springhill factory, communicate that as soon as you can, so that we can be prepared.
Changes come with the territory. They are not a problem. Just remember, the sooner we get those changes, the less likely they are to slow your project down.
Now, back to our question: How long does it take to make a video?
Do you want to know how long it will take to make your video?
Tell us about your project and we can tell you how long it will take to make your video.
Head on over to comprehensivmedia.com/videoanswers to learn more!

Welcoming Congregation Handbook Retired, To Be Revised
The UUA's Welcoming Congregation Program, which is celebrating its 25th anniversary! The LGBTQ world has changed dramatically since the program was conceived in 1989, and implemented in 1990. Today, over 70% of our congregations have been recognized as Welcoming Congregations. That includes over 95% of large and mid-sized congregations, and, now, over 50% of small congregations.
The Welcoming Congregation Program has been revised over the years to incorporate some of the changing realities for LGBTQ people, but, for a host of reasons, the last revision of the Welcoming Congregation Handbook was in 2002, four years before any state had legalized same-sex marriage!
Recently, the office of Multicultural Growth & Witness, which currently manages the Welcoming Congregation Program, has been encouraging congregations to rely more heavily on web resources we have curated and developed. However, despite outdated content, the Handbook has still been available through the UUA Bookstore as a guide for congregations. Until now, that is; the Welcoming Congregation Handbook is no longer being sold through the Bookstore.
Congregations seeking Welcoming Congregation status will be encouraged to access the web resources and design a program that is customized to fit its needs as a congregation. Find LGBTQ resources on uua.org (http://www.uua.org/lgbtq/).
Welcome and Inclusion in the 21st Century
It's time to take a new look at what welcoming means, what inclusion and hospitality mean, and how our multiple identities across race and ethnicity, abilities, class, sexual orientation, and gender identity/ expression inform who we are as whole people within Unitarian Universalism. Informed by the results of the Multicultural Ministries Sharing Project, which has been underway for the past year, the office of Multicultural Growth & Witness will now undertake re-envisioning the Welcoming Congregation for the next twenty-five years.
As the United States becomes a mosaic of diverse cultures, Unitarian Universalism can play a leadership role in adapting to and embracing this new reality, not unlike the one we played with LGBTQ rights over the last forty years. Throughout this process of revisioning, UUs will have formal and informal ways for to share their wisdom with the MG&W staff.

Steelers OL Continues Climb Up The Board In Latest PFF Positional Rankings
By Josh Carney
Coming off of arguably its best performance of the 2022 season, it's no surprise to see the Pittsburgh Steelers' offensive line climb another spot in the rankings in the latest offensive line rankings from Pro Football Focus.
In the 24-16 win over the Carolina Panthers, the Steelers offensive line dominated the point of attack throughout the matchup, rushing for 156 yards and three touchdowns while keeping backup quarterback Mitch Trubisky upright and relatively clean on the day, leading to the convincing Steelers win that wasn't as close as the final score indicated.
Thanks to that dominant performance in the trenches, the Steelers offensive line climbed one spot in the Week 16 rankings, moving up to No. 17 overall in the NFL, according to PFF's Sam Monson.
"Pittsburgh's line is significantly better as a pass-protecting unit than it is in run blocking. They rank eighth in pass-blocking efficiency and 23rd in run-blocking grade," Monson writes regarding the Steelers' offensive line. "Mason Cole was the only member of the line to surrender any pressure against Carolina."
The numbers from Pro Football Focus for the Steelers offense line is a bit shocking, quite honestly. The group has had serious issues in pass protection this season overall, allowing 35 sacks on the season to date. While the running game got off to a slow start, the Steelers have been much better on the ground since the Week 9 bye week.
That includes some impressive rushing performances against the New Orleans Saints, Cincinnati Bengals, Indianapolis Colts and Panthers in recent weeks.
In the win over Carolina, the #Steelers OL had quite a day, especially on the left side.
My film room on the success Pittsburgh had running the ball behind the left side of the OL. Via @Steelersdepot https://t.co/AYxMSXnScW
— Josh Carney (@ByJoshCarney) December 19, 2022
The offensive line feels much better equipped to come off the ball and move guys off the point of attack in the run game, compared to sitting back in pass protection overall on the year.
That thought will again be put to the test on Saturday night on Christmas Eve against the Las Vegas Raiders in a matchup that will feature star pass rushers in Chandler Jones and Maxx Crosby for the Raiders.
"Maxx Crosby is the main threat on the Raiders, boasting 62 total pressures and 52 defensive stops on the season. He lines up almost exclusively across from the right tackle," Monson writes.
Steelers head coach Mike Tomlin specifically highlighted the terrific pairing during his weekly media session ahead of the matchup with the Raiders as guys the Steelers will have to be ready for. That includes right tackle Chukwuma Okorafor, who will match up with Crosby.

Pall-bearers lower the coffin bearing the body of late reggae icon Frederick 'Toots' Hibbert during Sunday's interment service at National Heroes Park in Kingston. Hibbert, 77, died at the University Hospital of the West Indies in St Andrew on September 11.
Reggae icon Frederick 'Toots' Hibbert had a quiet burial amid few mourners on Sunday, a stark contrast to a bombastic career in which his distinctive voice and infectious smile made millions of fans across the globe and transformed stages into shrines of hero worship.
Hibbert, 77, was buried at National Heroes Park beside Dennis Brown following the intervention of Culture Minister Olivia Grange after a family dispute scuttled interment after his funeral in October.
Amid the COVID-19 pandemic, the efforts to give Hibbert a heroes send-off culminated on Sunday after his body lay in repose in major townships to allow adoring fans to get a final glimpse of the larger-than-life entertainer credited with giving reggae its name.
With more than 20 persons attending the burial, a few people stood on the outskirts of the burial site to observe the proceedings.
One of them was Michael Allen, who admitted that it was not his original intention to observe the burial but did so nonetheless after reality hit that it would be Hibbert's last day above ground.
"Toots is a great musician. I [was] sitting and watching CNN the other evening and seeing his music play in New York City and everybody singing to his music," he told The Gleaner.
Errol Williams, who also witnessed the burial from afar, said he had known the Grammy winner and his family for decades.
"I was the one who used to take the wife to supermarket back and forward for over 20 years.
'Toots, my bona fide friend, you pass off and gone, but sleep on. You are going to be missed all across the world," he said.
Sunday's ceremony featured musical tributes from well-known members of the local entertainment fraternity, among them saxophonist Dean Fraser, performing arts company Nexxus;,drummer Bongo Herman, and singer Dimario McDowell.
The tributes also included several medleys of Hibbert's vast musical repertoire.
The act of committal was undertaken by pastor of Fellowship Tabernacle in Kingston, the Rev Merrick 'Al' Miller, and Dr Carlene Davis.
Toots, a three-time winner of the Jamaica Festival Song competition, was one of the 10 finalists for 2020 with his entry Rise Up Jamaicans.
His greatest hits spanned five decades, among them Bam Bam, 54-46 (That's My Number), Monkey Man, Pressure Drop, and Pomps and Pride.
