FMM In the News: THE SUN DAILY, Wednesday, July 1, 2020 - PRESIDENT of the Federation of Malaysian Manufacturers (FMM), Tan Sri Soh Thian Lai recently engaged in a discussion with the energy related authority on a number of concerns.
Energy cost is a major cost factor to the industry which has significantly contributed to more than 37% of TNB electricity sales. Considering the current challenging period where little assistance has been provided for manufacturers to mitigate energy-cost impact caused by Covid-19 and the Movement Control Order, Soh put forward an appeal for the following:
* Extend the electricity tariff discounts to another 2 months and consider further discount of up to 5% as most companies especially those categorised as non-essentials did not benefit from it during April and May 2020 where usage is almost zero or minimal as productions were halted due to MCO, whereas they still have to bear the overheads and fixed costs.
* Electricity bills for February and March 2020 to be apportioned out for the affected companies similar to the easy payment plan offered to residential customers.
* Waiver of late payment penalty charges.
* Review of Maximum demand (MD) charge calculation for the month of March to reflect the days inoperation in view of the MCO
* Review the natural gas price to reflect the decline in global fuel prices, Indonesia has also reduced the price to USD6/mmBtu or equivalent to 25% reduction from the price Malaysian industries is paying currently.
* Waiver of the Take-or-Pay (TOP) penalty clause in consideration of possible prolonged impact of COVID-19 on businesses locally and globally to help lower business costs and sustain operations.
In addition to the above, FMM is also calling for Gas Malaysia Energy Services (GMES) Sdn Bhd to defer its decision to impose excess gas charges beginning from July 2020 until the economy recovers. FMM urgently calls for these reliefs to be duly considered expeditiously in order to support business and employment sustainability in view of the external uncertainties and long recovery period.

We are short ORCL from $40.47 current price $38.70. Lower stop to breakeven at $40.47 We are short AAPL from $111.79 current price $109.49. Lower stop to breakeven at $111.79 Lets see how the next few days go. Keep stop on short DIA at $192.55, and stop on long GDX at $20.13. We want to add longs on gold somewhere here….
Last Price 163'03" We went long at 162'03" on October 27th, so we netted $1,000 per contract profit. We want to stand aside and see how stocks act here…. Stocks could bounce here and that might allow bonds to drift back lower.
The following chart shows a recent double divergence between the OP/Price for December Crude Oil Futures. This setup is discussed on our online course "Wyckoff Wave Unleashed", Lecture 10, and shown on Chart 14. You can see that as the Technometer reached overbought at the blue circle, the price made its final high, and has been in a sustained downtrend since. It is now entering oversold territory, so we would expect a corrective rally.
We had a nice purchase price at $45.20 when the Wyckoff Tools gave us a low risk entry. The Technometer has now returned to overbought levels near 50 on AEM as well as GDX. We think risk is now much higher on this position, so we are going to sell at the market and watch this one on the next pullback. Current Price $49.00.
XPRO is a stock displaying many of the Wyckoff Principles in action….

\section{Introduction}
Inflation as a paradigm to explain horizon and flatness problem of early universe was first introduced by Guth \cite{guth1981}, and since has led to more than three decades of effort to build models of inflation that fit well with the observed CMB data (see Ref. \cite{martin2016} for a review). With the advent of high-precision observational data (like the recent Planck 2018 results \cite{planck2018x}), majority of scalar field driven inflation models have been ruled out while the ones in agreement are tightly constrained. More recently, new set of theoretical conditions called the Swampland criteria arise from the requirements for any effective field theory to admit string theory UV completion \cite{brennan2018,andriot2018,garg2018,obied2018,kallosh2019}, and further constrain scalar field potentials. There is thus a genuine interest to explore inflationary scenario with alternative driving fields. Some major programs include multiple fields, vector and/or gauge fields. For a comprehensive review, see Ref. \cite{martin2014}.

Among the theories not involving scalar fields, in particular those with vector fields \cite{ford1989,burd1991,golovnev2008,darabi2014,bertolami2015}, constructing successful models is often marred by ghost and gradient instabilities \cite{peloso2009,ryonamba2017} that lead to unstable vacua. Inflation with non-Abelian gauge fields have been shown to be free from these instabilities \cite{jabbari2011,jabbari2012,jabbari2013a,jabbari2013b}, but are in tension with Planck data and hence ruled out \cite{peloso2013}. Our endeavour is to explore inflation models with rank-2 antisymmetric tensor fields. Also referred to as the Kalb-Ramond fields, they appear naturally in the low energy limit of superstring models \cite{rohm1986,ghezelbash2009}. There are no observational signatures of antisymmetric fields in the present universe \cite{das2018}, but it is interesting to study them in the early universe when their presence may become significant\cite{elizalde2018}.

Past attempts at studying inflation with antisymmetric tensor have not been successful because of the possibility of ghosts as a generic feature of the theory \cite{koivisto2009a,aashish2018c}. Even with an unperturbed Friedmann Lemaître Robertson Walker (FLRW) metric background, the perturbations to field components admit ghosts and this result remains unaffected for different choices of couplings and potential. The cause of this instability can be traced to the presence of nondynamical modes for some components of the field, which in turn is due to the structure of the gauge invariant kinetic term in these models. It turns out that the choice of kinetic term is indeed not general \cite{altschul2010}, and one can in principle consider a model with modifications to the kinetic part of action.

In this work, we show that by working with a general kinetic term, it is possible to avoid ghost and gradient instabilities in antisymmetric tensor driven inflation in an unperturbed FLRW metric. The most general kinetic term for an even-parity antisymmetric tensor $B_{\mu\nu}$ upto quadratic order in field components and derivatives, is
\begin{eqnarray}
   \label{intro1}
   c_{1}\nabla_{\lambda}B^{\mu\nu}\nabla^{\lambda}B_{\mu\nu} + c_{2}\nabla_{\lambda}B^{\mu\nu}\nabla^{\mu}B_{\nu\lambda} + c_{3}\nabla_{\lambda} B^{\lambda \nu}\nabla_{\mu} B^{\mu }_{\ \nu},
   \end{eqnarray}
   which is equivalent to,
   \begin{eqnarray}
   \label{intro2}
   c_{4}H_{\lambda \mu \nu} H^{\lambda \mu \nu} + c_{5}\nabla_{\lambda} B^{\lambda \nu}\nabla_{\mu} B^{\mu }_{\ \nu}
   \end{eqnarray}
   upto some constant coefficients $c_{i}$. The first term in Eq. (\ref{intro2}) is the standard gauge invariant kinetic term, while the second term is a new non-gauge-invariant term and is taken into account in the present analysis. In fact, consideration of gauge-violating kinetic terms is not new in literature. Several vector and antisymmetric tensor field models with gauge-violating kinetic terms have been studied in the past extensively in the context of spontaneous Lorentz violation \cite{bluhm2008b,bluhm2009,hernaski2016}.

   The organization of this letter is as follows. In Sec. \ref{sec2}, we study the effect of modifying the kinetic part on the background cosmology for a particular choice of background structure of $B_{\mu\nu}$. We then study perturbations to $B_{\mu\nu}$ and subsequently the ghost and gradient instability in an unperturbed FRW spacetime, in Sec. \ref{sec3}. We conclude with a few remarks on future directions in Sec. \ref{sec4}.

   \section{\label{sec2}Background Cosmology}
   We begin by briefly reviewing the results of Ref. \cite{aashish2018c}, where the authors first considered the possibility of inflation driven by a rank-2 antisymmetric tensor. A typical action for antisymmetric inflation model has the form,
   \begin{eqnarray}
   \label{bga0}
   S_{I} = \int d^{4}x\sqrt{-g}\left(- \frac{1}{12} H_{\lambda \mu \nu} H^{\lambda \mu \nu} - V(B) + \mathcal{L}_{NM} \right).
   \end{eqnarray}
   where $V(B)$ is the potential, which in our case is quadratic, $m^{2}B_{\mu\nu}B^{\mu\nu}/4$,  and $\mathcal{L}_{NM}$ is a nonminimal coupling term. the metric signature ($- + + +$). $H_{\lambda \mu \nu}(B) = \nabla_{\lambda} B_{\mu \nu} + \nabla_{\mu} B_{\nu \lambda} + \nabla_{\nu} B_{\lambda \mu }$ ($\nabla_{\mu}$ is the covariant derivative) constitutes the kinetic term and admits gauge invariance under the transformation
   \begin{eqnarray}
   \label{bga1}
   B_{\mu\nu}\longrightarrow B^{\xi}_{\mu\nu} = B_{\mu\nu} + \nabla_{\mu}\xi_{\nu}-\nabla_{\nu}\xi_{\mu}.
   \end{eqnarray}

   A peculiar characteristic of antisymmetric tensor models is that while minimally coupled models generically fail to support inflation, those with nonminimal coupling can give rise to stable de-Sitter solutions and support slow-roll inflation. The choice of nonminimal coupling term does not affect the extent of support for inflation and is only restricted by theoretical constraints like stability near a Schwarzschild metric \cite{prokopec2006}. Specifically, upto quadratic order in $B_{\mu\nu}$ and second order metric derivative, allowed choices for $\mathcal{L}_{NM}$ are $B^{\mu \nu} B_{\mu \nu} R$ and $B^{\lambda \nu} B^{\mu}_{\ \nu} R_{\lambda \mu}$. However, for any choice of $\mathcal{L}_{NM}$ in action (\ref{bga0}) the perturbations to $B_{\mu\nu}$ in FLRW background admit ghosts \cite{aashish2018c,koivisto2009a} induced by the presence of nondynamical modes of perturbation. This rather generic problem has hindered the progress towards building inflation models with antisymmetric tensor, and remains to be addressed before any serious effort for analysing the full perturbation theory, including metric perturbations.

   Although all possible couplings upto quadratic order have been exhausted, and it might be tempting to explore higher order couplings of $B_{\mu\nu}$ and $R$ for a resolution to ghosts, modifications to the kinetic term of action (\ref{bga0}) as yet remain unexplored. Therefore, we start with constructing the most general kinetic term upto quadratic order in $B_{\mu\nu}$, which yields a new gauge-symmetry breaking kinetic term in addition to the gauge invariant kinetic term already present in action (\ref{bga0}) \cite{altschul2010},
   \begin{eqnarray}
   \label{bga2}
   \nabla_{\lambda} B^{\lambda \nu}\nabla_{\mu} B^{\mu }_{\ \nu}.
   \end{eqnarray}
   The action that we work with is then given by,
   \begin{eqnarray}
   \label{bga3}
   S = \int d^4x \sqrt{-g} \Big[- \frac{1}{12} H_{\lambda \mu \nu} H^{\lambda \mu \nu} + \dfrac{\tau}{2} (\nabla_{\lambda} B^{\lambda \nu})(\nabla_{\mu} B^{\mu }_{\ \nu}) + (\frac{\xi}{2\kappa}R - \frac{m^2}{4}) B^{\mu \nu}B_{\mu \nu} \nonumber \\ + \frac{\zeta}{2\kappa} B^{\lambda \nu }B^{\mu}_{\ \nu} R_{\lambda \mu}  \Big].
   \end{eqnarray}
   Of course, a whole new class of terms arise if one also takes into account the parity-odd dual tensor $\mathcal{B}_{\mu\nu}$, defined by \cite{altschul2010}
   \begin{eqnarray}
   \label{bga4}
   \mathcal{B}_{\mu\nu}\equiv \dfrac{1}{2}\epsilon_{\mu\nu\rho\sigma}B^{\rho\sigma}.
   \end{eqnarray}
   But we restrict ourselves to only parity-even terms for the sake of simplicity and because our goal is to show that it is indeed possible to avoid instabilities in models with antisymmetric tensor.

   Apart from ghost instability, inflationary solutions are prone to gradient instability, which occurs when the speed of sound becomes imaginary. Gradient (in)stability has not been checked explicitly for the model(s) (\ref{bga0}) before. For completeness, the gradient instability check has been performed for action (\ref{bga3}) in later part of this work, albeit in a relevant limit suited to check the effect of $\tau$ term.

   The background metric $g_{\mu\nu}$ is FLRW, with its components given by,
    \begin{eqnarray}
    \label{bga5}
    g_{00} = -1 , \quad g_{i j} = a(t)^2 \delta_{ij}.
    \end{eqnarray}
   Our choice of the background structure of $B_{\mu \nu}$ is motivated by the spacetime symmetries as well as calculational convenience, and is given by
    \begin{eqnarray}
    \label{bga6}
    B_{\mu \nu} =
    \begin{bmatrix}
    0 & 0 & 0 & 0\\
    0 & 0 & B(t) & -B(t)\\
    0 & -B(t) & 0 & B(t)\\
    0 & B(t) & -B(t) & 0
    \end{bmatrix},
    \end{eqnarray}
   along with a rescaling $B(t) = a(t)^{2}\phi(t)$, where $a(t)$ is the scale factor.

   The contribution of $\tau$ term (second in Eq. (\ref{bga3})) to the background cosmology is through the modifications in Einstein equation \textit{viz.} the corresponding energy-momentum tensor, $T^{\tau}_{\mu\nu}$, given by
    \begin{eqnarray}
    \label{bga7}
    T^{\tau}_{\mu \nu} = -\dfrac{2}{\sqrt{-g}}\dfrac{\delta S_{\tau}}{\delta g_{\mu\nu}} = \dfrac{\tau}{2} \Big[ g_{\mu \nu} \left(  (\nabla_{\lambda} B^{ \sigma \lambda })(\nabla_{\rho} B^{\rho }_{\ \sigma}) + 2 B^{\sigma \lambda} \nabla_{\lambda} \nabla_{\rho} B^{\rho}_{\ \sigma} \right) + 2 (\nabla_{\lambda} B^{\lambda}_{\ \mu})(\nabla_{\rho} B^{\rho}_{ \ \nu})\nonumber\\
     + 2\left( B_{\mu}^{\ \lambda} \nabla_{\lambda} \nabla_{\rho} B_{\nu}^{\ \rho} +  B_{\nu}^{\ \lambda} \nabla_{\lambda} \nabla_{\rho} B_{\mu}^{\ \rho} \right)  \Big].
    \end{eqnarray}
   Remarkably, upon substituting the background value of the metric and $B_{\mu \nu}$  in Eq.(\ref{bga7}), one finds that
    \begin{eqnarray}
    \label{bacb3}
    T^{\tau}_{\mu \nu}(B) = 0.
    \end{eqnarray}
   This implies, there is no additional contribution to the background cosmology of action (\ref{bga0}) and all results for theory (\ref{bga0}) follow from Ref. \cite{aashish2018c}, leading to the following conclusions:
   \begin{itemize}
   \item[(i)] de-Sitter solutions exist, and
   \item[(ii)] Slow roll inflation is supported.
   \end{itemize}
   As a side note, we point out that the vanishing $T^{\tau}_{\mu \nu}$ is specific to the choice of background Eq. (\ref{bga6}). It is certainly of academic interest to check for other choices of background, and we leave it as a future project.

\section{\label{sec3}Perturbations}
The interesting part however is when $B_{\mu\nu}$ is perturbed. Surely, the perturbed modes have nontrivial contributions from the $\tau$ term, as we shall see. A full perturbation analysis, where perturbations to both metric and field are considered, is ideally required to investigate the viability of an inflation theory. However, as a starting point and because of the complexity of full perturbation theory (involving a total of $10$(metric) $+ 6$(field) $= 16$ perturbed modes), it is useful to check the stability of just the field perturbations while keeping the metric unperturbed. In several past studies, instabilities have been found at this stage \cite{aashish2018c, koivisto2009a}.

Adding a perturbation $\delta B_{\mu\nu}$ to $ B_{\mu\nu}$, the perturbed action has the form,
\begin{eqnarray}
\label{pba0}
S[B+\delta B] &=& S[\delta B^{0}] + S[\delta B^{1}] + S[\delta B^{2}] \nonumber \\
&\equiv & S_{0} + S_{1} + S_{2},
\end{eqnarray}
where, terms have been segregated according to the order of perturbations. We are interested in the part of action that is quadratic in perturbations, $S_{2}$, since it leads to evolution equations of perturbed modes. Another trick that we use for our convenience is to Fourier transform the spatial part of all modes $\delta B_{\mu\nu}$,
\begin{eqnarray}
\label{pba1}
\delta B_{\mu\nu}(t,\vec{x})=\int \dfrac{d^{3}k}{(2\pi)^3}e^{-i\vec{k}\cdot\vec{x}}\delta \tilde{B}_{\mu\nu}(t,\vec{k}),
\end{eqnarray}
so that all spatial derivatives in the action get replaced by algebraic factors of $k$. In our calculations, we also utilize the freedom to choose the coordinate axis ($z-$axis) along momentum vector $\vec{k}$ so that all spatial derivatives along $x-$ and $y-$axes vanish. As a notation, throughout this paper, the coordinate ($\vec{x}$), time ($t$) and momenta ($\vec{k}$) dependence of all perturbed modes and their Fourier transforms are understood but not explicitly displayed, to save space. The resulting quadratic part of action, $\tilde{S}_{2}$, in general has a form,
\begin{eqnarray}
\label{pba2}
\tilde{S}_{2} = \int dt d^{3}k \sqrt{-g}\tilde{\mathcal{L}}_{2},
\end{eqnarray}
where $\tilde{\mathcal{L}}_{2}$ is the corresponding Lagrangian density expressed in terms of Fourier transformed modes $\delta \tilde{B}_{\mu\nu}$.

There are a total of six modes of perturbation to the field $B_{\mu\nu}$, which we represent as,
\begin{eqnarray}
\label{pba3}
\delta B_{\mu\nu} = \begin{bmatrix}
0 & -E_{1} & -E_{2} & -E_{3} \\
E_{1} & 0 & M_{3} & -M_{2} \\
E_{2} & -M_{3} & 0 & M_{1} \\
E_{3} & M_{2} & -M_{1} & 0
\end{bmatrix}.
\end{eqnarray}
Each of the perturbations $E_{i}$ and $M_{i}$ ($i=1,2,3$) form the componenents of two vectors $\vec{E}$ and $\vec{M}$ respectively, which are obtained after the time-space decomposition of $\delta B_{\mu\nu}$ \cite{altschul2010}.

 With the substitution of the Eq. (\ref{pba3}) in the action (\ref{bga3}), the quadratic (in perturbation) part of the action, $S_2$, is given by,
 \begin{eqnarray}
     \label{pba4}
     S_2[\vec{E},\vec{M}] = \int d^4 x \ \Bigg[ \frac{1}{2 a} \dot{\vec{M}}\cdot\dot{\vec{M}} +
\frac{\tau a}{2} \dot{\vec{E}} \cdot \dot{\vec{E}} +
      \dfrac{\dot{\vec{M}}\cdot(\vec{\nabla} \times \vec{E})}{a} +
\tau \left( aH \dot{\vec{E}} \cdot \vec{E} - \dfrac{\dot{\vec{E}} \cdot (\vec{\nabla} \times \vec{M})}{a} \right) \nonumber \\
      + \frac{\tau}{2a}\left( \dfrac{(\vec{\nabla} \times \vec{M}) \cdot(\vec{\nabla} \times \vec{M}) }{a^2} - 2 H \vec{E} \cdot (\vec{\nabla} \times \vec{M}) -(\vec{\nabla} \cdot \vec{E})^2   \right)\nonumber\\
     + \frac{1}{2a} \left((\vec{\nabla} \times \vec{E}) \cdot(\vec{\nabla} \times \vec{E})   -
     \frac{1}{ a^2}(\vec{\nabla}\cdot\vec{M})^2\right)
     - \alpha_1 a(\vec{E}\cdot\vec{E})
    + \alpha_2 \dfrac{(\vec{M}\cdot\vec{M})}{a}  \Bigg],
     \end{eqnarray}
     where $\alpha_1$ and $\alpha_2$ are the short hand notations for the coefficients of the non derivative terms in the action,
      \begin{eqnarray}
     \label{pba5}
     \alpha_1 &=& \frac{(6\xi + 2\zeta)}{\kappa} \dot{H} + \frac{(12 \xi + 3 \zeta)}{\kappa} H^2 - \frac{\tau}{2} H^2 - \frac{m^2}{2}, \nonumber\\
      \alpha_2 &=& \frac{(6\xi - \zeta)}{\kappa} \dot{H} + \frac{(12 \xi - 3 \zeta)}{\kappa} H^2 - \frac{m^2}{2}.
        \end{eqnarray}
   The vectors $\vec{E}$ and $\vec{M}$ can be further decomposed into a curl free and a divergence free part in the following way:
      \begin{eqnarray}
     \label{pba6}
     \vec{E} =\vec{\nabla}u+ \vec{U} , \quad
     \vec{M} = \vec{\nabla} v + \vec{V};
     \end{eqnarray}
     where, $\vec{U}$ and $\vec{V}$ are two divergence-free vector fields i.e ($\nabla_i U_i = \nabla_i V_i = 0$), whereas $u$ and $v$ are scalar fields. It can be shown that using Eq. (\ref{pba6}) in Eq. (\ref{pba4}), the scalar and vector parts of decomposition (\ref{pba6}) get decoupled, and $S_2$ can be written as,
      \begin{eqnarray}
     \label{pba7}
     S_2[\vec{E},\vec{M}] = S_{scalar}[u,v] + S_{vec}[\vec{U},\vec{V}],
     \end{eqnarray}
  where,
  \begin{eqnarray}
     \label{pba8}
     S_{scalar}[u,v] = \int d^4x \Big[ -\frac{1}{2a}\left( \dot{v}\nabla^2 \dot{v} + \tau a^2 \dot{u}\nabla^2 \dot{u}   \right) - \tau a H \dot{u}\nabla^2 u \nonumber\\
     - \frac{ (1+ \tau a^2) }{2a^3}(\nabla^2 u)^2\nonumber\\
     + \left(\alpha_1 a u\nabla^2 u - \alpha_2 \dfrac{v\nabla^2 v}{a}  \right)  \Big];\\
     \label{pba9}
     S_{vec}[\vec{U},\vec{V}] = \int d^4x \Big[
\frac{1}{2a} (\dot{\vec{V}} \cdot \dot{\vec{V}} + \tau a^2 \dot{\vec{U}} \cdot \dot{\vec{U}}) + \tau a H (\dot{\vec{U}} \cdot \vec{U}) + \nonumber\\
\frac{1}{a} \left( \dot{\vec{V}} \cdot (\vec{\nabla} \times \vec{U}) - \tau \dot{\vec{U}} \cdot (\vec{\nabla} \times \vec{V}) \right)\nonumber\\
- \frac{\tau H}{a} \vec{U} \cdot (\vec{\nabla} \times \vec{V}) - \alpha_1 a \vec{U} \cdot \vec{U} + 2 \alpha_2 \frac{\vec{V} \cdot \vec{V}}{a}
     \Big].
     \end{eqnarray}

   As described before, for the present analysis we Fourier transform $S_2$ in a suitable frame so that the momentum vector ($\vec{k}$) lies along z-axis, to obtain $\tilde{S}_2$. For convenience, we do not adopt different notations for Fourier transforms of functions since here onwards we only work in Fourier space. It turns out that in $\tilde{S}_2$, the vector part $\tilde{S}_{vec}[\vec{U},\vec{V}]$ can once again be written as a sum of two terms, $\tilde{S}_{vec}^{(1)}[U_x,V_y]$ and $\tilde{S}_{vec}^{(2)}[U_y,V_x]$, so that
   \begin{equation}
      \label{new0}
      \tilde{S}_2[\vec{E},\vec{M}] = \tilde{S}_{scalar}[u,v] + \tilde{S}_{vec}^{(1)}[U_x,V_y] + \tilde{S}_{vec}^{(2)}[U_y,V_x],
   \end{equation}
where,
   \begin{eqnarray}
\label{pba10}
\tilde{S}_{scalar}[u,v] = \int dt d^3k \  k^2 \Big[ \frac{1}{2a} (\dot{v}^{\dagger} \dot{v} + \tau a^2 \dot{u}^{\dagger} \dot{u}) + \frac{\tau a H}{2} (\dot{u}^{\dagger} u + h.c) - (\tau \frac{k^2}{2a} + a\alpha_1) u^{\dagger} u \nonumber\\
+ \frac{1}{2a} (2 \alpha_2 - k^2) v^{\dagger}v \Big] \\
\label{pba11}
\tilde{S}_{vec}^{(1)}[U_x,V_y] = \int dt d^3k \ \Big[ \frac{1}{2a} (\dot{V}_x^{\dagger} \dot{V}_x + \tau a^2 \dot{U}_y^{\dagger} \dot{U}_y ) + \frac{\tau a H}{2} (\dot{U}_y^{\dagger} U_y + h.c) \nonumber\\
+ \frac{ik}{2a} \left( (\dot{V}_x^{\dagger}U_y - h.c) + \tau (\dot{U}_y^{\dagger}V_x - h.c) - \tau H (V_x^{\dagger} U_y - h.c) \right)\nonumber\\
- a \alpha_1 U_y^{\dagger} U_y + \frac{\alpha_2}{a} V_x^{\dagger} V_x
 \Big]
\\
\label{pba12}
\tilde{S}_{vec}^{(2)}[U_y,V_x] = \int dt d^3k \ \Big[ \frac{1}{2a} (\dot{V}_y^{\dagger} \dot{V}_y + \tau a^2 \dot{U}_x^{\dagger} \dot{U}_x ) + \frac{\tau a H}{2} (\dot{U}_x^{\dagger} U_x + h.c) \nonumber\\
- \frac{ik}{2a} \left( (\dot{V}_y^{\dagger}U_x - h.c) + \tau (\dot{U}_x^{\dagger}V_y - h.c) - \tau H (V_y^{\dagger} U_x - h.c) \right)
- a \alpha_1 U_x^{\dagger} U_x + \frac{\alpha_2}{a} V_y^{\dagger} V_y
 \Big]
\end{eqnarray}

Our objective now is to check for the ghost and gradient instability in $\tilde{S}_2[\vec{E},\vec{M}]$. Ghosts appear in a theory whenever the kinetic term(s) acquire a negative sign, implying a negative and thus unbounded kinetic energy.  Gradient instability appears due to wrong sign before the momentum square term in the action as it leads to an unbounded Hamiltonian, and at high energies the gradient instability can act as ghost \cite{wolf2019}. In what follows, we derive conditions avoiding ghosts and gradient instability in the present model.

\subsection{Ghost Instability}
The relevant term for analysing ghosts in Eq. (\ref{new0}) is its kinetic part, which can be cast into the form,
\begin{eqnarray}
   \label{gi0}
   \tilde{S}^{kin}_{2} = \int dt d^{3}k \dot{\Delta}^{\dagger}T\dot{\Delta},
\end{eqnarray}
where, $\Delta$ is an array consisting of all perturbed modes, and is given by,
\begin{eqnarray}
   \label{gi1}
   \Delta = \begin{bmatrix}
   v \\
   V_x \\
   V_y \\
   u \\
   U_y \\
   U_x
   \end{bmatrix}; \quad
   \Delta^{\dagger} = \begin{bmatrix}
   v^{\dagger} & V_{x}^{\dagger} & V_{y}^{\dagger} & u^{\dagger} & U_{y}^{\dagger} & U_{x}^{\dagger}
   \end{bmatrix}.
\end{eqnarray}
The coefficients of kinetic terms in Eq. (\ref{new0}) are encompassed in the matrix $T$ which reads,
\begin{eqnarray}
   \label{gi2}
   T = \begin{bmatrix}
   \dfrac{k^{2}}{2a(t)} & 0 & 0 & 0 & 0 & 0\\
   0 & \dfrac{1}{2a(t)} & 0 & 0 & 0 & 0 \\
   0 & 0 &\dfrac{1}{2a(t)} & 0 & 0 & 0\\
   0 & 0 & 0 & \dfrac{k^{2}a(t)\tau}{2} & 0 & 0\\
   0 & 0 & 0 & 0 & \dfrac{a(t)\tau}{2} & 0\\
   0 & 0 & 0 & 0 & 0 & \dfrac{a(t)\tau}{2}
   \end{bmatrix}.
   \end{eqnarray}
   Note that there are no off-diagonal terms present and there are no non-dynamical modes in $\tilde{S}_{2}$, which leads us to conclude that there are no ghosts provided that the coupling $\tau$ satisfies a simple no-ghost condition:
   \begin{eqnarray}
   \label{gi3}
   \tau > 0.
   \end{eqnarray}
   Clearly, when $\tau = 0$, modes $u, \ \vec{U}$, become nondynamical and would lead to ghosts \citep{aashish2018c}.

 \subsection{Gradient Instability}
Gradient instability can be checked by evaluating the speed of sound, $c_s$ in a given theory. An imaginary value for the sound speed implies gradient instability. To calculate $c_s$ in the present model, one needs to first derive the equations of motion from action (\ref{new0}). For this purpose, we introduce three ($2\times 1$) matrices $\Delta_{i}$ ($i=1,2,3$) defined as,
 \begin{eqnarray}
   \label{pbb2}
   \Delta_1 =
   \begin{pmatrix}
   u\\v
   \end{pmatrix} ; \quad
   \Delta_2 =
   \begin{pmatrix}
   U_x\\V_y
   \end{pmatrix} ; \quad
   \Delta_3 =
   \begin{pmatrix}
   U_y\\V_x
   \end{pmatrix};
   \end{eqnarray}
   and vary Eq. (\ref{new0}) with respect to $\Delta^{\dagger}_{i}$ ($i=1,2,3$) to obtain,
 \begin{eqnarray}
\label{pbb1}
\ddot{\Delta}_1 + \Xi_1 \dot{\Delta}_1 + \Sigma_1 \Delta_1 = 0; \nonumber\\
\ddot{\Delta}_2 + \Xi_2 \dot{\Delta}_2 + \Sigma_2 \Delta_2 = 0; \\
\ddot{\Delta}_3 + \Xi_3 \dot{\Delta}_3 + \Sigma_3 \Delta_3 = 0; \nonumber
\end{eqnarray}
and $\Xi_{i}$ and $\Sigma_{i}$ are the coefficient matrices of order $(2 \times 2)$ given by,
 \begin{eqnarray}
 \label{pbb3}
 \Xi_1 =
 \begin{pmatrix}
 H & 0\\
 0 & -H
 \end{pmatrix} \quad \quad
 &\Sigma_1 =
 \begin{pmatrix}
 \dot{H} + H^2 + \frac{k^2}{a^2} + \frac{2 \alpha_1}{\tau} & 0\\
 0 & k^2 - 2\alpha_2
 \end{pmatrix}\nonumber\\
 \Xi_2 =
 \begin{pmatrix}
 H & -\frac{ik(\tau + 1)}{a^2 \tau}\\
 -ik(\tau + 1) & -H
 \end{pmatrix} \quad \quad
 & \Sigma_2 =
 \begin{pmatrix}
 \dot{H} + H^2 + \frac{2\alpha_1}{\tau} & \frac{2ikH}{a^2}\\
 -ikH(\tau - 1) & -2\alpha_2
 \end{pmatrix}\nonumber\\
 \Xi_3 =
 \begin{pmatrix}
 H & \frac{ik(\tau + 1)}{a^2 \tau}\\
 ik(\tau + 1) & -H
 \end{pmatrix} \quad \quad
 &\Sigma_3 =
 \begin{pmatrix}
 \dot{H} + H^2 + \frac{2\alpha_1}{\tau} & -\frac{2ikH}{a^2}\\
 ikH(\tau - 1) & -2\alpha_2
 \end{pmatrix}
 \end{eqnarray}
 A reasonable assumption for solutions to Eq. (\ref{pbb1}) in the deep subhorizon is to take $\Delta_{i} \propto \exp[-i\int^{t}c_{si}k/a(t')dt']\vec{e}_{i}$ as the solution to eigenvector equation (\ref{pbb1}), where $c_{si}$ is the sound speed and is treated as constant ($\dot{c}_{si}\ll k$) \cite{emami2017}, and $\vec{e}_i$ is a constant vector. Substituting this ansatz in Eq.(\ref{pbb1}) and neglecting $\dot{c}_{si}$ terms, we get quadratic equations in terms of $c_{si}^2$,
  \begin{eqnarray}
 \label{pbb5}
 \Big[ c_{s1}^2 - 1- \frac{a^2}{k^2}\left( \dot{H} + H^2 + \frac{2\alpha_1}{\tau}  \right) \Big] \Big[ c_{s1}^2  - 2ic_{s1}\frac{aH}{k} -a^2 + \frac{2\alpha_2 a^2}{k^2}\Big] &=& 0; \\
 \label{pbb6}
 c_{si}^4 - 2i c_{si}^3 \frac{aH}{k} + \Big[ \frac{a^2}{k^2} \left( 2\alpha_2 - \frac{2\alpha_1}{\tau} - \dot{H} - H^2 \right) - \frac{(\tau +1)^2}{\tau} \Big]c_{si}^2 \nonumber\\
 + 2ic_{si}\frac{aH}{k} \Big[ \frac{a^2}{k^2} \left( \dot{H} + H^2 + \frac{\alpha_1}{\tau} \right) + \frac{(\tau + 1)^2}{2\tau}  \Big] - 2(\tau - 1) \frac{a^2 H^2}{k^2} &=& 0, \ i=2,3.
 \end{eqnarray}
 A theory suffers from gradient instability when the speed of sound, $c_{si}$ (defined in the relativistic fluid approximation, see Ref. \cite{dodelson2003}), becomes imaginary. Hence, to avoid gradient instability one must demand that $c_{si}^{2}>0$. Solving Eqs. (\ref{pba5}) and (\ref{pba6}) for $c_{si}^2$ will lead to conditions for avoiding gradient instability. However, our current interest is limited to deep subhorizon, where $k >> aH$. In other words, we restrict ourselves to high momentum limit. In fact, while instabilities can arise in the low momentum limit, they have been shown to be Jeans-like instabilities and may thus be under control \cite{sotiriou2016}. Solving above equations in the limit $k >> aH$ leads to,
  \begin{eqnarray}
 \label{pbb7}
 c_{s1}^2 = 1-\frac{a^2 m^2}{k^2 \tau} \ , \
a^2(1+\frac{m^2}{k^2});
 \end{eqnarray}
 and for $j=2,3$:
 \begin{eqnarray}
 \label{pbb9}
 c_{sj}^2 = 0, \ \frac{(\tau +1)^2}{\tau} + \frac{a^2 m^2}{k^2} \frac{(\tau - 1)}{\tau}.
 \end{eqnarray}
 From Eqs. (\ref{pbb7}) and (\ref{pbb9}), and taking into account the positivity of $\tau$ given by Eq. (\ref{gi3}), the conditions on $\tau$ required for a positive $c_{si}^{2}$ (where $i=1,2,3$) are,
 \begin{eqnarray}
 \label{pbb8}
 \tau > \frac{a^2 m^2}{k^2},\nonumber \\
 \tau > - \left( 1+ \frac{a^2 m^2}{2k^2}\right) + \sqrt{\frac{2 a^2 m^2}{k^2}\left(1+\frac{a^2 m^2}{8k^2}\right)}.
 \end{eqnarray}
Conditions (\ref{pbb8}) along with (\ref{gi3}) constrain the parameter $\tau$ for which the theory (\ref{bga3}) is free of ghost and gradient instabilities. In fact, it is straightforward to check that in the limit $k\to\infty$, these conditions reduce to $\tau > 0$ and are trivially satisfied.

\section{\label{sec4}Conclusion}
We showed that by including a new kinetic ($\tau$) term in the action (\ref{bga0}) it is possible to avoid ghost instabilities in perturbations. This can be attributed to the absence of nondynamical modes that otherwise lead to ghosts \cite{koivisto2009a,aashish2018c}. For our choice of background $B_{\mu\nu}$, the $\tau$ term does not affect background cosmology. We performed gradient instability analysis for perturbations in $B_{\mu\nu}$ and derived conditions on $\tau$ to avoid gradient instability. In the high momentum limit ($k\to\infty$), the theory is trivially free from ghost and gradient instabilities for all positive $\tau$.

The results of this analysis present a strong case for more detailed investigations of ghost, gradient and other instabilities for perturbations including the metric part, and should motivate further directions in inflation model building. The choice of kinetic term (\ref{intro2}) also motivates further analysis of the physical degrees of freedom, that can be addressed through Hamiltonian analysis using $3+1$ ADM decomposition. An important aspect of academic interest is to study the effect of different choices of background structure of $B_{\mu\nu}$. Another interesting problem is to explore the cosmology and viability of parity-odd terms, which the authors plan to pursue in future. Additionally, studies involving the higher order terms of $B_{\mu\nu}$ and gravity may also be explored.

Why I Like Google Apps For Work
We got our first email system when we moved into a building where an IT consultant was also a tenant. He wired us into his system and we used his domain name. The monthly cost was affordable and there were no maintenance headaches or costs. It was 1993 and Al Gore had just invented the Internet two years before. We were 'on it'.
Over time all those drawing attachments started clogging up his email server, so we got our own email server with our own domain name. The cool factor balanced out the costs and hid the fact that we were stepping out on a slippery slope.
It took a few years for the real aggravation to set in. Server upgrade with new software licenses (per user), occasional mysterious downtimes that usually meant a bill for $400-$600 to fix it. Modest but consistent annoyances became part of being connected.
Finally everybody on the planet got email. That meant that a whole lot of jackasses now had email. A jackass plus email equals spam. By 2008 each of us were receiving 200 emails a day - 95% spam. I was spending a half hour per day sorting and deleting - and that was after developing special tactics for efficiently sorting and deleting. Mondays were a nightmare.
There was a solution. Buy a spam filter for just $15/user/month. If it wasn't 2008 and the start of the great recession, I might have done it.
Instead I found Google Apps.
Here's what I like about Google Apps:
Cost - $5/user/mo. Period. Zero additional cost.
Image - A new custom domain is included. Now you can look like a business. Or use your old domain.
Storage - 30 GB of cloud storage for email and files. Share files.
Backups - Automatic backups.
Anywhere Access - Log on from anything that has Internet access.
Finding stuff - Add Labels, more than one if you like. Search for a name, domain, phrase, whatever - it's Google! Use filters to file, forward, tag, etc.
Always On - 99.9% uptime and 99.9% aggravation-free time.
Drive is a storage area where you can use folders like any server, and share those folder if you wish. The 30 GB you start with is often adequate, but Google offers the lowest cost for additional storage.
Calendars integrate with email and can also be shared. Create a shared office calendar.
Docs is Google's answer to Word. It is free and has all the features that I ever used, so it's bloat-free. Easily export to other file formats even while making the document an attachment.
Sheets is an Excel-lookalike.
Sites is the ability to create in-house websites for projects, intranet, etc.
AddOns! There are some really amazing third party apps that extend the use of Docs and Sheets. Merging or splitting cell contents. Bulk email merges. Sorting by color. Gantt charts. And on and on.
Google Apps For Work Is A Solution For So Much More Than Just Email.
Get out of the IT business.
I used Google Apps for my architecture firm and use it for Architekwiki, too. The cost is minimal, and you don't give up anything. If you want to try Google Apps, use my links. I will receive a small commission if you remain a user for several months. Thank you.

When it comes to security on your computer, there are a number of areas that should be considered.
You must always use strong passwords that cannot be guessed by anyone and they should never be reused anywhere else.
This obviously makes sense for maximum security but:
What is a strong password?
How do you come up with a strong password?
How do you remember the strong password?
The answer to these questions is not that complicated.
A strong password is obviously one that cannot be guessed or derived through some automated process. An example of a strong password is: Jg4uyG3B87dTg%x. This is using characters randomly put together using a total of 15 characters which include 4 numbers, 1 symbol and upper and lowercase letters.
Another example is using words which may be easier to remember. An example is: musty-eject-thing-quackery using 4 words and hyphens.
So, how do you come up with these strong passwords? The simplest answer is to use software such as 1Password by AgileBits (https://1password.com) or in the case of the Mac, it has a program called Keychain Access which will store passwords generated such as when you create an account in the browser or change your password, it will suggest to create a strong password for you and store it in the Keychain.
Once you have created these strong passwords, then you never have to remember them again as they will be available to you when you need them. In the case of 1Password, you only ever have to remember the password to 1Password to access all your other passwords.
In the latest versions of MacOs and iOS, the passwords created and stored by Keychain carry across your devices and if you also have 1Password, you can open that if the password is stored in it.
Use for your Apple ID, Google, Facebook, Microsoft and everywhere it is available. It will ensure that there is no unauthorised access to your accounts.
Microsoft uses its Authenticator app on you mobile device and Google use their Authenticator app which a number of third parties such as Square, Amazon, Airtable, Synology etc use.
Disable Automatic Login
Do not allow your computer to login without an account and a password. Require passwords for each account on the computer or in the case of a mobile device, ensure that it is protected by some form of authentication at all times, whether that is FaceID, finger print, passcode or whatever method your device uses.
Don't Trust Emails or Text Messages
If you receive an email or a text from an unknown source that is unsolicited, do not click on any links or in fact on anything in the email or message.
Banks do not send you links for you to click nor do any sensible organisations. If you think it may be legitimate, go to the site you know and check it out, not via a link in the email or message.
Phone Call Scams
There are many scams out there which include ones where they pretend to have detected an issue with your computer. Just hang up.
More recently, you may receive phone calls from unknown locations and numbers but they hang up before you have a chance to answer. They want you to phone back as they are a premium call that will cost you a great deal of money as they will waste your time as much as possible.
Don't phone back any of these numbers!
Online Scams
Be aware of any scams involving buying, selling and job offers.
Do not trust any public WiFi hotspots. Do not do anything such as banking or where you need to use account details unless its a https site (secure) or use a VPN service.
Install the latest security updates and OS updates and third party software updates.
Read news sources and keep up with the latest threats.

Apple bans Facebook from tech tools for tracking teen browsing habits
Apple Inc said on Wednesday it had banned Facebook Inc from a program designed to let businesses control iPhones used by their employees, saying the social networking company had improperly used it to track the web-browsing habits of teenagers.
Apple offers what are known as certificates that let businesses have deep controls over iPhones, with the potential to remotely install apps, monitor app usage and access, and delete data owned by a business on an iPhone. Apple designed the program for organizations whose staff use iPhones for official duties, when privacy needs are different from phones for personal use.

US govt orders security measures for DNS hijack emergency
Iran blamed for "almost unprecedented scale" attacks compromising web and email traffic.
The United States Department of Homeland Security has issued an emergency directive in response to a serious, global campaign of domain name system (DNS) infrastructure tampering, believed to originate in Iran.
Earlier in January, security vendors Cisco Talos and Mandiant FireEye outlined a spate of DNS hijacks against multiple government, telcos and internet infrastructure organisations in Europe, North America and the Middle East/Africa.
Attackers have successfully redirected web and email traffic by altering DNS records, making them point to servers on addresses that they control.
They've been able to do so by capturing administrative credentials for administrative accounts that can make changes to DNS records. FireEye and Talos said they have received reports that sophisticated phishing attacks were used to gain acccess for DNS record manipulation, as well as compromising a victim's domain registrar account.

Mozilla warns decryption laws will break open source
Mozilla is worried that Australia's proposed decryption laws will break the principles and licensing terms of open source software.
The foundation said in a submission to the government that being forced to secretly create vulnerabilities in an open source product would be extremely difficult.
Mozilla express a number of concerns, including:
The limitation on systemic vulnerabilities is inadequate.
The key provision seeking to limit the widespread security risks of this bill is a prohibition on forcing companies to build a "systemic vulnerability" into their systems or to prevent them from rectifying a systemic vulnerability. However, the term "systemic" is not defined
in the bill, leaving dangerous ambiguity that could be exploited by the government. The accompanying Explanatory Document provides some additional clarity but not confidence in stating that systemic vulnerabilities exclude "actions that weaken methods of
encryption or authentication on a particular device."
The Government goes on to say that this legislation would permit "requir[ing] a provider to enable access to a particular service, particular device or particular item of software."
For a company to enable this capability would effectively be to create a systemic vulnerability, whether the capability is provided by "one-off" upgrades sent to specific devices or by inserting a remote access capability to all versions of their products. In
either case, the company will be left with a fast-path method to compromising their user's data, thus creating a high risk of compromise by malicious actors.

Apple says decryption should 'alarm every Australian'
Apple has laid out some of the ways it could be forced to spy on its customers if the decryption bill before Australian parliament passes into law.
The bill "could allow the government to order the makers of smart home speakers to install persistent eavesdropping capabilities into a person's home, require a provider to monitor the health data of its customers for indications of drug use, or require the development of a tool that can unlock a particular user's device regardless of whether such tool could be used to unlock every other user's device as well", Apple said in a parliamentary submission.
In the submission, Apple said, "The encryption technology built into today's iPhone represents the best data security available to consumers. And cryptographic protections on the device don't just help prevent unauthorized access to your personal data — they're a critical line of defense against a criminal who seeks to implant malware or spyware, and use the device of an
unsuspecting person to gain access to a business, public utility or government agency."
They go open to say "While the bill presents many questions and opportunities for clarification, we focus our comments on several overarching themes: (1) overly broad powers that could weaken cybersecurity and encryption; (2) a lack of appropriate independent judicial oversight, (3) technical requirements based only on the government's subjective view of reasonableness and practicability, (4) unprecedented interception requirements, (5) unnecessarily stifling secrecy mandates, and (6) extraterritoriality and global impact.".

Decryption laws edge closer to reality
The federal government will move to introduce legislation for its crackdown on encrypted communications services in the upcoming spring sitting of parliament, a year after it first promised to do so.
It plans to present the legislation – dubbed the Telecommunication and Other Legislation Amendment (Assistance and Access) Bill – before December 7 this year.
I have heard the arguments from ordinary users stating that they have nothing to hide so why should they care? There are a number of aspects to this.
1. Whilst the government is not a corrupt totalitarian regime, you may have little to fear from them but history has shown that this is not guaranteed and can change very quickly.
2. Your communications which expose personal information such as your banking information, your username and password for the various services you access etc. should always be secure and encrypted. If the government has a backdoor then what stops criminals from exploiting this back door? Its a valid argument because trusting the custodians of the backdoor key has been proven to be folly as it will always be exploited. Just look at the leaks from supposedly secure government organisations such as the NSA, CIA and FBI in the US.
3. On another level, if your data can be decrypted in transit by third parties, what is there to stop this information from being mined and used for marketing or to profile individuals for other purposes?
4. If you are not convinced that it is a bad idea, just think about the countless millions of accounts that have been hacked due to the custodians of your personal data being hacked. This information has been used to steal money, create false identities for other criminal activities etc.
It's interesting that governments that were formerly conservative in their thinking are now on the bandwagon of trying to impose these types of laws. Historically it was always more likely to come from the left of politics that would push such ideas.

Mark Zuckerberg Talks To Wired About Facebook's Privacy Problem
When you are the product as with Facebook and Google, if you want to maintain some privacy, you need to be careful what information you provide to their services. Most do not seem to care, do not understand or believe the trade-off for providing your personal data is out-weighed by the person benefits.
In the past, it was very difficult to work out what your privacy settings actually were and would change, often without users being aware. This has improved but it is still very difficult to work out some of the settings. For example, to delete you Facebook account can be problematic because even if you do find where to do it, should you inadvertently connect to Facebook again from some device, it negates your deletion.

Reuters reported that the EU is preparing legislation to force companies to turn over customers' personal data.
This is a world-wide trend for governments to seek getting access to encrypted data on the premise that it is to keep society safer.
In Australia, there is a movement to have decryption legislation which will allow access to users' data.
The argument is always that this access is to assist in fighting crime and to protect society. Individuals may say that I have nothing to hide so why not but this is potentially very dangerous if governments are able to spy on everyone at anytime. Past experience has shown that this sort of power has been abused by governments to silence or eliminate opposition groups.

Australia's Notifiable Data Breaches scheme is now in effect
The Notifiable Data Breaches (NDB) scheme comes into effect today, requiring agencies and organisations in Australia that are covered by the Privacy Act to notify individuals whose personal information is involved in a data breach that is likely to result in "serious harm", as soon as practicable after becoming aware of a breach.

MacOS and iOS Updates
Apple has released supplemental updates for macOS to 10.13.3. and iOS 11.2.6 to fix a bug that caused devices to crash when trying to process specific Unicode characters.
The problem relates to rendering certain Indian characters which could cause the device to crash.
Apparently some mischievous people have intentionally inserted these characters to cause problems for those unfortunate to have encountered them.
Its always a good idea to keep devices up-to-date, especially relating to security issues.

Since 1962, Burma has been ruled by a military junta. Life has deteriorated markedly for its citizens. Despite its former prosperity and its rich resources, it was voted least developed nation by the UN in 1987, and human rights atrocities continue to prevail. Forced from their homes by the government, more than 100,000 people live in refugee camps along the border between Burma and Thailand; hundreds of thousands more hide in jungles on the Burma side. They are the Karen people, one of the largest ethnic groups in Burma.
Don't Fence Me In chronicles the life of 70-year-old freedom fighter Major Mary On and her people's struggle for self-determination. Mary explains how the Karen are fighting for their very survival; the Burmese military's goal is "to wipe the Karen away so if you want to see them you'll have to go see them in the museum. See just an image or picture." Her charismatic storytelling is accompanied by rare, clandestine footage smuggled out of the Karen refugee camps.
She illuminates the plight of the Karen still inside Burma, having little food and hiding in the jungle, yet proving remarkably resilient. While the Karen have lost their land, their way of life, and many of those who lived and fought beside them for independence, they have not lost their ties to a rich and beautiful history that transcends their present day despair. The film reveals the Karen refugees' spirit and determination to survive as political and historical forces conspire against them. Don't Fence Me In is an eloquent and moving chronicle of human rights abuses that must finally be brought to the attention of the global community.

In the book Only The Good Die Young by K.K. Hendin, Milcah wants that lyric tattooed on her arm to prove it's not only the good ones who die young. Milcah has cancer and believes she is going to die. She wants that tattoo because it reminds her of herself, an I told you so for at her wake. Very morbid, I know. In case she doesn't die of the cancer and gets to grow old, it still has the same purpose and even proves her point.

New Zealand's merchandise trade deficit narrowed in July from the same month last year as imports such as crude oil fell faster than exports such as milk powder and meat.
The trade deficit was $433 million last month, from a surplus of $110 million in June and from a deficit of $730 million in July 2015, Statistics New Zealand said. The annual trade gap narrowed to $3.03 billion from $3.3 billion in the 12 months to June 30, NZ Newswire reported.
A monthly deficit of $350 million and an annual gap of $2.98 billion was expected, based on a Reuters survey.
Falling crude oil prices contributed to a 10% decline in imports to $4.4 billion in July from a year earlier, accounting for more than one-third of the $503 million decline.
The drop reflected a decline in global crude oil prices and in the volume imported, Statistics New Zealand said. Brent crude dropped as low as $27.88 a barrel in January and had recovered to $50.35 a barrel by the start of July, down from about $62 a barrel a year earlier.
Global crude prices also had a bearing on New Zealand's dairy exports, with energy export-dependent Algeria recording the biggest decline in shipments of New Zealand dairy products last month—down 55% by value and 45% by quantity. Algeria is the third-biggest market for New Zealand milk powder.
Overall New Zealand milk powder exports fell by 23%, or $118 million, last month, while the quantity rose 0.9%, contributing to a 4.9% decline in total exports to $4 billion. Meat and edible offal exports fell by 19%, or $97 million.
Exports of fruit fell 5.7% by value but rose 3.9% by volume last month.
China remained New Zealand's largest market in the 12 months ended July 31, taking a total $9.1 billion, up 3.6% from a year earlier. Exports to Australia fell 1.3% to $8.4 billion, exports to the US rose 0.2% to $5.6 billion and to Japan rose 0.9% to $3 billion.
Asia was the biggest regional market, taking $21.8 billion of New Zealand's total $48.6 billion of exports, up 3.6% in the year.
China was also the largest source of imports, sending $10.5 billion of goods to New Zealand in the latest year, up 10%, resulting in a $1.4 billion bilateral trade deficit for New Zealand.
Australia was second, sending $6.5 billion of products, up 3.4%, while the US was in third place on $6.1 billion, down 0.4%.
New Zealand's exports of dairy products fell 8% to $11.1 billion in the latest year, while meat exports rose 0.5% to $6.5 billion, logs and wood rose 10.4% to $3.9 billion and fruit jumped 24% to $2.6 billion.
