\section{Introduction}

Open charm mesons consist of a quark (antiquark) belonging to the charm ($c$) flavor and an antiquark (quark) from the light quark flavor sector.  The estimation of the strong magnetic fields produced in the peripheral ultra-relativistic heavy ion collision experiments at LHC in CERN and at RHIC in BNL \cite{skokov, fukushima, deng, tuchin, kharzeev}, has initiated the study of the hadron properties in the presence of magnetic fields \cite{Hosaka}. The experimental observables from the relativistic heavy ion collision experiments are related to the medium modifications of the hadrons. There is a profuse production of the open heavy flavour mesons and the quarkonium in the early phase of these collisions. The increase of the chiral condensate with magnetic field is called the magnetic catalysis \cite{Shovkovy, elia, kharzeevmc}. In the literature, there have been studies of the magnetic catalysis properties on quark matter in the Nambu Jona Lasinio model \cite{Preis, menezes, ammc, lemmer, guinjl}. The effects of magnetic catalysis have been studied on the nuclear matter phase transition using the Walecka model and an extended linear sigma model in \cite{haber}, resulting in the increasing nucleon mass with magnetic field at zero density, zero magnetic moments. There the magnetic catalysis effect was observed indirectly through the scalar field dependency of the nucleon mass ($M_N=m_N-g_{\sigma}\sigma$). In \cite{arghya}, the effects of magnetized Dirac sea have been studied under the weak-field approximation in presence of a constant, external background magnetic field. An increase of nucleon mass with magnetic field was observed in the Walecka model at zero density, with significant contribution from the anomalous magnetic moments of the Dirac sea of nucleons. At finite temperature, an inverse magnetic catalysis \cite{balicm} effect was observed on the critical temperature of nuclear matter phase transition. In the literature, a few number of studies are there on the magnetized Dirac sea effects on the nuclear matter properties. The magnetized Dirac sea effects have been studied on the in-medium masses of the open charm (bottom) \cite{dmc, bmc} and the ground states of heavy quarkonia \cite{chrmmc}, in the magnetized nuclear matter. The masses of the heavy quarkonia were calculated in the QCD sum rule approach by using the medium modified quark and gluon condensates in terms of the scalar fields calculated within the chiral $SU(3)$ model. On the other hand, the in-medium masses of the open heavy flavor mesons are obtained by solving their corresponding dispersion relations in terms of the number and scalar densities of the nucleons and the scalar fields fluctuations within the chiral effective model. The effects of magnetic catalysis are incorporated through summation over the nucleon tadpole diagrams with the magnetized fermion propagators of the Dirac sea of nucleons. The scalar fields of the chiral effective model correspond to the QCD condensates (scalar, isoscalar, $\sigma \sim \langle \bar{u}u \rangle$, scalar, isovector, $\delta \sim (\langle\bar{u}u \rangle -\langle\bar{d}d \rangle)$ etc.) Thus, the increasing values of the scalar fields with the magnetic field, indicate indirectly a catalysis effect, which are studied on the masses of the heavy flavor mesons.
Open charm mesons can be important tools in probing the magnetic catalysis, and other hadronic properties. $D$ and $D^*$ mesons are the pseudoscalar and vector open charm mesons, respectively, comprising of a charm quark (antiquark) and a light (u,d) antiquark (quark). We investigate the effects of a  magnetic field on the decay widths of the vector meson ($D^*$) going to pseudoscalar mesons ($D$ and $\pi$) and the charmonium states $\Psi(3770)$ going to $D\bar{D}$, by using their masses in the magnetized nuclear matter, accounting for the magnetic field modified Dirac sea effects. Study of the hadron properties under extreme conditions of density, temperature and magnetic field is of relevance in the ultra-relativistic heavy ion collision experiments and in astrophysical objects like the magnetars, neutron stars etc. Time evolution of the produced field created in such high energy heavy ion collision is still an open question, needs further solutions of the magnetohydrodynamic equations with the proper estimation of the electrical conductivity of the medium \cite{tuchin}.

 Heavy quarkonia and open heavy flavor mesons (Open Charm mesons in this case) are produced in the early stages of the collisions,  and as such are more sensitive to the magnetic field.\\ The in-medium masses of the heavy flavor mesons are calculated in the magnetized nuclear matter by using the chiral effective model approach in the absence of magnetic catalysis \cite{am97, am98, nikhil}.
 The hadronic decay widths have been calculated using the $^3P_0$ model \cite{3p0a,3p0b,3p0c,3p1, 3p2, 3p0d,3p0e,3p0f,3p0g,3p0h}. In the $^3P_0$ model, a light quark-antiquark pair is created in the $^3P_0$ state (with quantum numbers similar to that of vacuum, $J^{PC} = 0^{++}$), and this light quark (antiquark) combines with the heavy charm antiquark (light quark (u or d)) of the decaying $D^*$ state at rest, resulting in the production of the open charm, $D$ meson and a light flavor meson, the $\pi$ meson \cite{Friman,AK}. The matrix element for the decay of the $D^*$ meson state depends on the momentum $|\textbf{p}|$ of the outgoing daughter meson states. The in-medium partial decay widths of charmonium (bottomonium) going to open charm (bottom) mesons ( for e.g., $\Psi(3770)\rightarrow D\bar{D}$ and $\Upsilon(4S)\rightarrow B\bar{B}$ ) have been studied using a field theoretic model for composite hadrons with quark (and antiquark) constituents \cite{102, amsm31, amsm30}, as well as within a light quark-antiquark pair creation model or the $^3P_0$ model \cite{am55}, in presence of an external magnetic field, without accounting for the Dirac sea effects. The PV mixing effects between the longitudinal component of the vector and the pseudoscalar charm (bottom) mesons at finite magnetic field, have been studied \cite{amsm30, amsm31, Machado, Gubler, cho91, G2, 102, suzuki, Iwasaki, qcdsrc, qcdsrb, Alford} without considering the magnetic catalysis effect and in \cite{chrmmc, dmc, bmc} including the catalysis effect for the heavy quarkonia and open heavy flavor mixing. Effects of magnetic fields on the masses and hence on the decays, are seen to be dominant through the PV mixing effects. The in-medium hadronic decays of the vector open charm meson, $D^*\rightarrow D\pi$ ($\bar{D}^*\rightarrow \bar{D}\pi$) have also been studied incorporating the PV mixing effects between $D-D^{*||}$ ($\bar{D}-\bar{D}^{*||}$) and the lowest Landau level (LLL) contributions for the charged mesons at finite magnetic field, without considering the effects of magnetic catalysis on their masses \cite{amsm30}.

 We organize the paper as follows: In section \ref{sec2}, we discuss in detail the lowest Landau level contribution on the masses of the charged mesons. The Pseudoscalar-Vector (PV) mixing in the presence of an external magnetic field is described by the effective Lagrangian approach in section \ref{sec3}. In-medium masses of the open charm and charmonium, within the chiral effective model are discussed in section \ref{sec4}. In section \ref{sec5}, using the $^3P_0$ model, the decays of the  vector $D^*$ and $\Psi(3770)$ mesons are described.  In section \ref{sec6}, we present the results of the current investigation. In section \ref{sec7}, we summarize the findings of this work.

 \section{Lowest Landau Level contribution}
\label{sec2}
We investigate the effects of a uniform magnetic field on the masses of the open charm $(D,D^*)$ mesons. The charged $D \ (D^{\pm})$ and $ D^*\ (D^{*\pm})$ mesons receive contributions from the lowest Landau level (LLL) at finite magnetic field. The external magnetic field contributes to the energy of the pseudoscalar and vector mesons as \cite{Gubler},

\begin{equation}
    E_P(n,p_z) = \sqrt{m_P^2 + (2n+1)|eB| + p_z^2}
\end{equation}
\begin{equation}
    E_V(n,p_z) = \sqrt{m_V^2 + (2n+1)|eB| + p_z^2 + gS_z|eB|}
\end{equation}

Here the Landau levels are indicated by the integer $(n\geq 0)$, z-component of momentum as $p_z$, z-component of the spin quantum number as $S_z$. We assume that the external magnetic field is along the z$-$direction (Momentum in the x-y plane is discretized, momentum along the z-direction is unaffected). We consider g, the Lande g-factor is equal to 2 (Not considering the case of Anomalous Magnetic Moment). For strong magnetic fields, and assuming $p_z$ is very small, equations (1) and (2) modify into -
\begin{equation}
    E_P = \sqrt{m_P^2 + |eB| }
\end{equation}
for the pseudoscalar mesons, and
\begin{equation}
    E_{V^{\perp}_{+1}} = \sqrt{m_V^2 + 3|eB| } ,\quad S_z = +1
\end{equation}
\begin{equation}
    E_{V^{\parallel}} = \sqrt{m_V^2 + |eB| } , \quad S_z = 0
\end{equation}
\begin{equation}
    E_{V^{\perp}_{-1}} = \sqrt{m_V^2 - |eB| } ,\quad S_z = -1
\end{equation}
for the transverse ($V^{\perp}_{+1,-1}$) and longitudinal ($V^{||}$) components of the vector mesons. In writing the above expressions for the LLL contribution, the internal structure of the charged mesons are neglected \cite{LLL, amsm31}. Due to the strong external magnetic field, the triplet vector meson states which were degenerate, have now split into three distinct energy levels.

\section{Pseudoscalar-Vector Mixing}
\label{sec3}
 The vector $D^*$ [$\Psi(3770)$] and the pseudoscalar $D$ $[\eta_c(2S)]$ mesons interact via an effective interaction vertex. The z-component of the spin can exist as a good quantum number for the meson system \cite{G2,Gubler}. The vector meson, with the spin polarization along the direction of an external magnetic field, is called the longitudinal component of the vector meson state. Mixing occurs between the longitudinal component of the vector meson and the pseudoscalar meson. The effective interaction vertex accounting for this mixing effect is \cite{amsm30,102, Gubler, cho91, dmc, chrmmc},

 \begin{equation}
     \mathcal{L}_{PV\gamma}=\frac{g_{PV}}{m_{av}}e\tilde{F}_{\mu\nu}(\partial^{\mu} P)V^{\nu}.
 \end{equation}

 P and $V^\mu$ represent the pseudoscalar and the vector fields, respectively. $\tilde{F}_{\mu\nu}$ and $m_{av}$ are the dual field strength tensor of the external magnetic field and the average mass $(m_{av} = (m_P+m_V)/2)$.
 The coupling constant, $g_{PV}$ in equation (7), is fitted from the observed values of the corresponding radiative decay widths, given by,
 \begin{equation}
      \Gamma_{V\rightarrow P+\gamma}=\frac{1}{12\pi}\frac{e^2g_{PV}^2{\tilde{p}}^3}{ m_{av}^2}
 \end{equation}
 with $\tilde{p}= (m_V^2-m_P^2)/{2m_V}$ is the magnitude of the center of mass momentum of the products in the final state. The masses of the pseudoscalar and the longitudinal component of the vector mesons undergo a Pseudoscalar-Vector (PV) mixing, thereby causing a mass shift in the $[D-D^{*||}\ (\bar{D}-\bar{D}^{*||})]$ and $[\Psi(3770)-\eta_c(2S) ]$ meson states as follows
 \begin{equation}
     m_{V,P}^2=\frac{1}{2}\left(M_+^2+\frac{c_{PV}^2}{m_{av}^2}\pm\sqrt{M_-^4+\frac{2c_{PV}^2 M_{+}^2}{m_{av}^2}+\frac{c_{PV}^4}{m_{av}^4}}\right)
 \end{equation}
  with $M_{\pm}^2 = m_V^{{*}^2} \pm m_P^{{*}^2}$ and $c_{PV}=g_{PV}eB$; with $m_{V,P}^{*}$ are the effective vector and pseudoscalar meson masses in the magnetized nuclear medium as will be explained in the next section, with the additional contribution from the lowest Landau level for the charged mesons, as given in equations.(3)-(6).
  Equation (9) can also be written as
  \begin{equation}
      m_{V,P}^2 = m^{*2}_{V,P} \pm \frac{c_{PV}^2}{{M_{-}}^2}
  \end{equation}
  by considering the terms up to the second order in $c_{PV}$ and leading order in $(m_V-m_P)/2m_{av}$.\\
  The total decay width for the neutral meson, viz. the $D^{*0}$ meson, has not been measured. However, the branching ratio for $\Gamma(D^{*0} \rightarrow D^0 \pi^0):\Gamma(D^{*0} \rightarrow D^0 \gamma) = 64.7:35.3$, is known \cite{PDG}. Hence, the coupling constant involved in the radiative decay width can be obtained if the coupling constant of ($D^{*0}\rightarrow D^0 \pi^0$) is known. From isospin symmetry considerations, this coupling constant can be related to the corresponding charged mesons ($D^{*\pm}$) decay modes as follows \cite{Gubler},
 \begin{equation}
     g[D^{*0} \rightarrow D^0 + \pi^0] = \frac{1}{\sqrt{2}}\ g[D^{*+} \rightarrow D^0 + \pi^{+}]
 \end{equation}
 \begin{equation}
     g[D^{*0} \rightarrow D^0 + \pi^0] = g[D^{*+} \rightarrow D^{+} + \pi^0]
 \end{equation}
 Similarly for their charge conjugate modes. In this way, the coupling constant for the radiative decay width  and the PV mixing parameter for the neutral D mesons can be obtained. The coupling constant $g$ is fitted from the measured decay width $\Gamma  [D^* \rightarrow D \pi]$ in vacuum.

  \section{In-medium masses of charmonium and open charm mesons}

  \label{sec4}

  An effective chiral model Lagrangian is applied to study the in-medium masses of charmonium and open charm mesons in asymmetric nuclear matter in the presence of strong magnetic field. The original version of the chiral $SU(3)_L\times SU(3)_R$ model is based on the non-linear realization of chiral symmetry \cite{coleman, weinberg, bardeen} and broken scale invariance of QCD \cite{Papa, Zeschi, AM2}, which occurs through a logarithmic potential given in terms of a  scalar dilaton field, $\chi$ \cite{erikk}.
  The generalized Lagrangian density is written as \cite{Papa}

\begin{equation} \label{eq1}
\mathcal{L} = \mathcal{L}_{kin} + \mathcal{L}_{BM} + \mathcal{L}_{vec} + \mathcal{L}_0 + \mathcal{L}_{SB} +\mathcal{L}_{scalebreak} + \mathcal{L}_{mag}
\end{equation}
\\
$\mathcal{L}_{kin}$ represents  the kinetic energy
of the baryons and the mesons. $\mathcal{L}_{BM}$ gives the baryon-meson interaction, $\mathcal{L}_{vec}$ refers to the interactions of the vector mesons, $\mathcal{L}_0$ is  the meson-meson interaction, $\mathcal{L}_{SB}$ is the explicit chiral symmetry breaking term.
$\mathcal{L}_{scalebreak}$ is a scale invariance breaking logarithmic potential given in terms of a
scalar dilaton field. $\mathcal{L}_{mag}$ is the contribution from the magnetic field \cite{Prakash, Wei, Brodrik, am97, am98, nikhil}
\begin{equation} \label{eq2}
\mathcal{L}_{mag}= -\overline{\psi}_i q_i\gamma_{\mu}A^{\mu}\psi_{i} -\frac{1}{4}\kappa_{i}\mu_N\overline{\psi}_i\sigma^{\mu\nu}F_{\mu\nu}\psi_i-\frac{1}{4}F^{\mu\nu}F_{\mu\nu}
\end{equation}

where, $\psi_i$ is the field operator for the $i^{th}$ baryon (i = p, n, for nuclear matter, as considered
in the present work).
The values of $\kappa_p$ and $\kappa_n$ are given as $3.5856$ and $-3.8263$ respectively, which are the values of the gyromagnetic ratio
corresponding to the anomalous magnetic moments of the proton and neutron (tensorial interaction with the electromagnetic field) respectively.  In the magnetized nuclear medium, the magnetic field contribution occurs through the Landau energy levels of the charged particles and through the anomalous magnetic moment of the nucleons. The magnetic field dependent Dirac sea contribution to the self energy of the nucleons is  incorporated through the scalar densities of the proton and the neutrons \cite{chrmmc, dmc, bmc} in the context of the chiral model.

The Lagrangian density is written as per the chiral SU(3) model in the mean field approximation. The scalar fields are solved from the coupled equations of motion, derived from the Lagrangian density under mean field approximation. In-medium masses of the open charm mesons in magnetized asymmetric nuclear matter in presence of strong magnetic field is obtained using the chiral effective model by generalizing the chiral SU(3) to chiral SU(4) and deriving interactions of the charmed mesons with the light hadronic sector \cite{am97, dmc, am81, am4}. Dispersion relations for the open charm mesons viz., $D \ (D^+, D^0)$ and $\bar{D} \ (D^-, \bar{D}^0)$ are obtained from the Fourier transform of the equation of motion of these mesons from the chiral effective Lagrangian \cite{dmc, am97}. Besides, they also incur additional mass shifts from the lowest Landau levels (for the charged mesons). The medium modification of the dilaton field gives the modification in the gluon condensate, which causes modification in the charmonium mass in the presence of strong magnetic field \cite{Lee, am81, am98}.

  \begin{equation}
    \Delta m_{\Psi} = \frac{4}{81}(1-d)  \int dk^2 \Bigg \langle \Bigg | \frac{\partial \psi(\Vec{k})}{\partial \Vec{k}}\Bigg |^2\Bigg \rangle \frac{k}{k^2/m_c + \epsilon}(\chi^4-\chi_0^4)
\end{equation}
with
\begin{equation}
   \Bigg \langle \Bigg| \frac{\partial \psi(\Vec{k})}{\partial \Vec{k}}\Bigg|^2\Bigg\rangle = \frac{1}{4\pi} \int \Bigg| \frac{\partial \psi(\Vec{k})}{\partial \Vec{k}}\Bigg|^2 d\Omega
\end{equation}

Where, $m_c$, the charm quark mass is taken to be 1.95 GeV \cite{am98}, $m_\Psi$ is the vacuum mass of the given charmonium state, and  $\epsilon = 2m_c - m_\Psi$ is the binding energy; $\Psi(\Vec{k})$ is the wave function of the charmonium state in momentum space. The Gaussian form of the wave functions in coordinate space are given in \cite{am81, am98, Friman}.

 \section{The $^3P_0$  model}
 \label{sec5}
 In this section we discuss the hadronic decay widths of ($D^* \rightarrow D  \pi$, $\bar{D}^* \rightarrow \bar{D}  \pi$ ) and $(\Psi(3770)\rightarrow D\bar{D})$, by taking into account the internal structures of the parent and the outgoing mesons using the $^3P_0$ model \cite{Friman}.
\subsection{Decay of the Open Charm mesons}
 \label{subsecA}
 The uniform magnetic field results in the mass modification of the $(D,D^*)$ mesons. This modifies the resulting decay widths for the various channels. From the $^3P_0$ model, the decay width of the vector open charm meson, $D^*$ going to $D \pi$ is given by  \cite{am55, Friman, 3p0f}:
 \begin{equation}
     \Gamma_{D^*\rightarrow D\pi} =  {\frac{\sqrt{\pi}E_DE_\pi\gamma^22^8r^3(1+r^2)^2x^3}{2m_{D^*}\ 3(1+2r^2)^5}}\ exp\Bigg(-\frac{x^2}{2(1+2r^2)}\Bigg)
     \end{equation}

In this expression, $m_{D^*}$ is the mass of the parent $D^*$ meson. $E_D$ and $E_\pi$ are the energies of the outgoing $D$ and $\pi$ mesons respectively;
     \begin{equation}
         E_D = (p^2 + m_D^2)^{1/2} ;  \  E_\pi = (p^2 + m_{\pi}^2)^{1/2}
     \end{equation}
with $m_D$, the modified $D$ meson mass and $m_\pi$ as the $\pi$ meson mass. $p$ is the 3-momentum in the center of mass (c.o.m) frame.

\begin{equation}
    p = \bigg[\frac{m_{D^*}^2}{4} - \frac{m_D^2 + m_{\pi}^2}{2} - \frac{(m_D^2 - m_{\pi}^2)^2}{4m_{D^*}^2}\bigg]^{1/2}
\end{equation}
$\gamma$ is the coupling constant related to the strength of the $^3P_0$ vertex \cite{3p0f,3p0g,3p2}. It signifies the probability for creating a light quark-antiquark pair. The wave functions of the $(D^*,D)$ mesons are assumed to be  wave functions with harmonic oscillator potential. The ratio $r = \beta/\beta_{avg}$, where $\beta$ is the strength of the harmonic potential of the parent $D^*$ meson state and $\beta_{avg}$ is the average strength of harmonic oscillator potential of the daughter $(D-\pi)$ mesons. The scaled momentum $x$ is defined as $x = p/\beta_{avg}$. The value of $\beta_D$ is taken as 310 MeV, consistent with the decay widths of $\psi(4040)$ to $D\bar{D}, D^*\bar{D}, D\bar{D^*},$ and$ D^*\bar{D^*}$ in vacuum \cite{3p1,AK,Lee}. Decay widths depend on the variable, $x$, which is the center of mass momentum, $p$
in units of $\beta_{avg}$, as a polynomial multiplied by an exponential term.

\subsection{Decay of $\Psi(3770)$ meson to $D\bar{D}$}
The hadronic decay width for the charmonium state, $\Psi(3770)$ going to $D\bar{D}$ mesons is calculated in this subsection, using the $^3P_0$ model. The in-medium masses of the parent and daughter particles are obtained from the chiral effective model calculations, with the additional contribution of LLL (for charged mesons only) and PV mixing effect, in the magnetized nuclear matter, including magnetic catalysis. The decay width expression is given by \cite{am55, Friman}
\begin{multline}
\Gamma_{\Psi(3770) \rightarrow D\bar{D}} = \frac{ \gamma_{\Psi}^2\sqrt{\pi} E_D  E_{\bar{D}} }{2m_{\Psi (3770)}}\frac{2^{11} 5}{3^2}  \left(\frac{r_{\Psi}}{1+2r_{\Psi}^2}\right)^7 \times\\ x_{\Psi}^3 \left(1-\frac{1+r_{\Psi}^2}{5(1+2r_{\Psi}^2)}x_{\Psi}^2 \right)^2
 exp \left(-\frac{x_{\Psi}^2}{2(1+2r_{\Psi}^2)}\right)
\end{multline}

with $E_D = (p_D^2 + m_D^2)^{1/2}$ and     $ E_{\bar{D}} = (p_D^2 + m_{\bar{D}}^2)^{1/2}$ and

\begin{equation}
    p_D = (m_{\Psi}^2/4 - m_D^2 )^{1/2}
\end{equation}

Similar to the previous decay channel $(D^* \rightarrow D \pi)$,  $\gamma_{\Psi}$ signifies the probability for creating the light quark-antiquark pair. $\gamma_{\Psi}$ is chosen to be 0.33  \cite{AK}, thus reproducing the observed decay widths of $\Psi(3770)$ to $D^+D^-$ and $D^0\bar{D}^0$ in vacuum. The ratio $r_{\Psi}=\beta_{\Psi} / \beta_D $ with $\beta_{\Psi} = 0.37$ and $\beta_D = 0.31$ (in GeV) are obtained from the mean squared radius for the D meson and the charmonium states. $\beta_{D} = 0.31$ GeV  \cite{Lee}, is consistent with decay widths of $\Psi(4040)$ to $D\bar{D}, D^*\bar{D}, D\bar{D}^*$ and $D^*\bar{D}^*$ in vacuum.
$x_{\Psi}=p_D/ \beta_D$ is the scaled momentum.

\section{Results and Discussions}
\label{sec6}
In this section, we discuss the results on the in-medium hadronic decay widths for $D^*\rightarrow D\pi$ ($\bar{D}^*\rightarrow \bar{D}\pi$) and $\Psi(3770) \rightarrow D\bar{D}$ channels, in the magnetized nuclear matter, accounting the effects from the magnetized Dirac sea. The in-medium masses of the pseudoscalar open charm mesons $D \ (D^+, D^0)$, $\bar{D}\ (D^-, \bar{D}^0)$ are calculated within the chiral effective model. The magnetized Dirac sea contributions are taken through the additional terms of the scalar densities of protons and neutrons on the scalar fields of the model, which represent the chiral condensates. The effects of Landau quantization of the protons in the Fermi sea are considered along with the Dirac sea effects in the magnetized nuclear matter. The in-medium masses of the vector mesons  $D^* \ (D^{*+}, D^{*0})$, $\bar{D}^*\ (D^{*-}, \bar{D}^{*0})$, are obtained from the mass shifts of the corresponding pseudoscalar partners (equation (10) of ref. \cite{dmc}). The in-medium masses of the pseudoscalar mesons are solved from their dispersion relations (equation (3) of ref. \cite{dmc}), which depend on the scalar and number densities of the nucleons and the scalar fields fluctuations from their vacuum expectation values (equations (4)-(5) of ref.\cite{dmc}). However, the fluctuation in the charm (a heavy quark flavor) quark condensate is neglected in the mass calculations. Thus, the medium effects are incorporated in terms of the number and scalar densities and the scalar fields fluctuations on the open charm mesons masses within the chiral effective model. The magnetic field contributions are also considered due to the lowest Landau level of the charged meson state (being considered as particle entity) (equations (3)-(6)). There is no such additional effect for the neutral mesons. Although, the dominant magnetic field effects on the masses, are coming through the PV mixing between the pseudoscalar and the longitudinal component of the vector mesons. Using the fitted values of the coupling parameters from the observed radiative decay widths of the charmonium and open charm mesons, an effective Lagrangian approach is applied to find the PV mixing effect on the in-medium masses of $D-D^{*||}$, $\bar{D}-\bar{D}^{*||}$ and $\eta_c(2S)-\Psi(3770)^{||}$ states (equation (10)), in the magnetized nuclear matter, by considering the effects from magnetic catalysis (MC). In the PV mixing calculations, the contribution from the lowest Landau level is considered in the case of electrically charged open charm mesons. However, the mass modifications of the excited charmonium state, $\Psi(3770)$ depend on the in-medium changes of the scalar dilaton field, $\chi$, which simulates the gluon condensate of QCD within the chiral model framework. The mass modification for the $\Psi(3770)$ is calculated using equation (15), in the magnetized nuclear medium by accounting the effects of Dirac sea from the the magnetized fermionic tadpole diagrams. The Landau quantization of protons in the nuclear medium are also considered along with Dirac sea effects at finite magnetic field. All along, the  effects of anomalous magnetic moments of the nucleon are considered in the magnetized Fermi sea of nucleons and in the magnetized Dirac sea. \\ Therefore, using the in-medium masses of the open charm and charmonium states, the effects of magnetic catalysis are studied on the possible hadronic decay channels of $D^*\rightarrow D\pi$ ($D^{*+}\rightarrow D^{+}\pi^0$, \ $D^{*+}\rightarrow D^0\pi^+$, $D^{*0}\rightarrow D^0\pi^0$); $\bar{D}^*\rightarrow \bar{D}\pi$ ($D^{*-}\rightarrow D^{-}\pi^0$, $D^{*-}\rightarrow \bar{D}^0\pi^-$, $\bar{D}^{*0}\rightarrow \bar{D}^0\pi^0$) and $\Psi(3770) \rightarrow D\bar{D}$. A light quark-antiquark pair creation model or the $^3P_0$ model is used in our present investigation, to study the hadronic decay widths for the vector open charm meson, $D^*$ going to two pseudoscalar mesons, $D$ and $\pi$ using equation (17). Due to the isospin considerations, the coupling constant related to the $^3P_0$ vertex for the various channels are different. For the channels $D^{*\pm}\rightarrow D^{\pm}\pi^0$, and $D^{*+}\rightarrow D^0\pi^+$ (with its charge conjugate mode, $D^{*-}\rightarrow \bar{D}^0\pi^-$),  $\gamma$ is chosen to be 0.265 and 0.368 respectively. For $D^{*0}\rightarrow D^0\pi^0$ it is 0.264 (including the charge conjugate channel). The decay of $\Psi(3770)$ to $D\bar{D}$ can be possible by two decay modes, namely, $D^+D^-$ and $D^0\bar{D}^0$, which are calculated within the $^3P_0$ model to find the total decay width of $\Psi(3770)$, by equation (20). \\
In Fig.1, the hadronic decay widths for the neutral $ D^{*0} \ (\bar{D}^{*0})$ mesons to pseudoscalar mesons $D^0\ (\bar{D}^0)$ and $\pi^0$, are plotted for zero density matter, as a function of the magnetic field, $eB$ (in units of $m_{\pi}^2$). The magnetic catalysis effects are shown by accounting (and not) the anomalous magnetic moments of the Dirac sea of nucleons at $\rho_B=0$. There is no Landau quantization effects of protons on the masses due to the absence of nuclear matter part. In the absence of Dirac sea polarizations, only the PV mixing effects between $D^0 - D^{*0||}$ and $\bar{D}^0-\bar{D}^{*0||}$ on their vacuum masses, have impact on the decays at finite magnetic field. At zero density, decay widths are shown only up to $|eB|=5.4\ m_{\pi}^2$ in the case of with AMM, since the masses have been calculated till this range of magnetic field \cite{dmc}.\\ In the decay calculations, PV mixing effects are considered on the masses of the longitudinal ($S_z=0$) component of the vector mesons, to find the decay width of the corresponding polarization state of the vector meson, $D^{*||}\ (\bar{D}^{*||})$. In this case, the final state decay product, pseudoscalar meson, $D\ (\bar{D})$, mass is taken to be its corresponding PV mixed value. The decay widths for the non-PV mixed, transverse components ($S_z=\pm1$) of the vector mesons, $D^{*\perp}\ (\bar{D}^{*\perp})$, are calculated separately for their decays into the corresponding non-PV mixed, pseudoscalar state, $D (\bar{D})$ and a $\pi$ meson. The lowest Landau level (LLL) contribution for the transverse components of vector mesons are different for charged particles, as it is given by equation (4) for $S_z=+1$ component and equation (6) for $S_z=-1$ component of spin-polarizations. However, there is no LLL contribution at finite magnetic field for the neutral vector as well as neutral pseudoscalar mesons.  In Fig.2, in-medium decay widths are shown for the charged open charm mesons at zero density. For the charged mesons there are two decay modes for the $D^{*+}$ meson, $D^{*+}\rightarrow D^+\pi^0$ (denoted as I.a), $D^{*+}\rightarrow D^0\pi^+$ (denoted as II.a) and two for the $D^{*-}$ meson, $D^{*-}\rightarrow D^-\pi^0$ (denoted as I.b), $D^{*-}\rightarrow \bar{D}^0\pi^-$ (denoted as II.b). The decay widths are also calculated for nuclear matter saturation density, $\rho_0$ both in case of symmetric (with $\eta=0$) and asymmetric (with $\eta=0.5$) nuclear matter, in Figs. [(3)-(4)] for the neutral and in Figs. [(5)-(6)] for the charged open charm mesons. Next, the decay widths for the charmonium state, $\Psi(3770)\rightarrow D\bar{D}$ are shown in the magnetized nuclear matter taking into account the magnetic catalysis effects on the respective parent and daughter particle masses within the chiral effective model. The zero density calculation are shown in Fig.(7). The finite density, decay widths are shown in Figs.[(8)-(9)], at $\rho_0$ and $\eta=0,\ 0.5$, respectively. The two decay modes of $\Psi(3770)$ to $D^+D^-$ (denoted as I) and $D^0\bar{D}^0$ (denoted as II) are shown separately in the plots, along with their total values (I+II). The effects of PV mixing are also considered on the masses of the initial and final states particles, including the catalysis effect in presence of magnetic field. The effects of magnetic catalysis on the in-medium decay widths are seen to be important through the incorporation of nucleons anomalous magnetic moments. The effects of magnetic catalysis are appreciably visible on the decays of charged vector charm mesons in comparison to their neutral partners decay widths. However, the in-medium decay widths of $\Psi(3770)\rightarrow D^0\bar{D}^0$ channel get significant modifications over the $\Psi(3770)\rightarrow D^+D^-$ mode, by the magnetized Dirac sea polarizations accounting the anomalous magnetic moments of the nucleons, as compared to the no catalysis case. As in the case of charged vector charm meson decay widths, containing two decay modes, the dominant contribution is coming from the $D^{*+}\rightarrow D^0\pi^+$ ($D^{*-}\rightarrow \bar{D}^0\pi^-$) as compared to the $D^{*+}\rightarrow D^+\pi^0$ ($D^{*-}\rightarrow D^-\pi^0$) decay mode. There is observed to be important difference in the partial decay widths of $\Psi(3770)\rightarrow D\bar{D}$ through the PV mixing effects of $\eta_c(2S)-\Psi(3770)^{||}$ and $D-D^{*||}$ ($\bar{D}-\bar{D}^{*||}$), as compared to the no mixing case, both in presence and absence of the magnetic catalysis effect.

\section{Summary}
\label{sec7}

We have investigated the in-medium hadronic decays  of $D^{*\pm}\rightarrow D^{\pm}\pi^0$, $D^{*+}\rightarrow D^{0}\pi^+$, $D^{*-}\rightarrow \bar{D}^0\pi^-$, $D^{*0} \rightarrow D^0\pi^0$, $\bar{D}^{*0}\rightarrow \bar{D}^0\pi^0$  and $\Psi(3770) \rightarrow D\bar{D}$, in the magnetized nuclear matter incorporating the effects of the magnetic catalysis through the Dirac sea polarization, within the chiral effective model. For the charged mesons, the contribution of the lowest Landau level has been considered. Pseudoscalar-Vector (PV) mixing has also been incorporated through the effective Lagrangian approach.
 The Landau level lifts the degeneracy of the energy levels of the vector $(D^{*\pm})$ mesons as the transverse components of the charged vector mesons undergo energy shifts. The coupling parameter $g_{PV}$ is fitted from the observed radiative decay widths, $\Gamma(V\rightarrow P \gamma)$. The decay width for the $D^{*0} \rightarrow D^0 \pi^0$ channel, is currently seen but not measured. However, from isospin considerations, we can estimate the variation of this decay width with varying magnetic field. The effects of magnetic catalysis on the in-medium partial decay widths of open charm and charmonium states can affect the yield of open charm and charmonia produced in the non-central, ultra-relativistic, heavy ion collision experiments, where produced magnetic field is very large.

The first daily blog of #SF12 is here!
Hi, my name's Sean, I'm 16. I'm in the SF 12 production of 'A Midsummer Nights Dream' playing the part of Demetrius.
Today in rehearsals we did a full read-through of the play, and then after lunch we worked on our characters and their relationships with the other characters in the play, which I really enjoyed and found incredibly useful.
I don't really know who my favourite actor is, there are just so many. But my favourite performer would definitely be Matt Bellamy of Muse, he's just so talented.
If I could play any role in any film, it would definately be Batman. It would be so good!
I think people should come see my show as it will be really interesting to watch as it's a promenade performance, and I think it will be really different to any previous Summer Festival show!
Summer Festival is just really great and with the new 6 week course I feel like I'm learning so much, and that it will definitely help me with a career in acting.

At some point in time everyone one of us is going to experience glass breakage and the first question is always going to be:
"How did this glass break?"
Broken laminated glass. Designed for shards to remain in place when broken to safeguard the object until the glass is replaced. Shatter resistance safeguards against injury and damage.
Sometimes the answer can be obvious, like a baseball hitting it. Today, we will focus on some other factors that are not so obvious, and on laminated glass strength.
Considerations:
The first thing to consider is the design of the glass part. If it is fabricated with sharp 90 degrees inside corners, it will be doomed from the start. A radius is always needed in these areas. See image below for different edge finishes.
Depending on the size of the glass and how it will be used, you will need to consider using the correct thickness and type of glass.
Hole locations are another critical consideration, especially if the glass is going to be tempered for added strength and safety considerations.
Even the type of edge finish can have a dramatic effect on the strength of the glass.
Three different edge finishes on Tru Vue UltraVue Laminated Glass. Top piece – Flat Edge Polish; Middle piece – Flat Edge Grind; Bottom piece – Waterjet cut edge
Testing UltraVue® Laminated Glass Strength
We tested the strength of Tru Vue® UltraVue® Laminated Glass (4.4mm thickness) to demonstrate how much stronger the glass can be with the proper edge finish applied to it. Find out which edge finish makes the glass stronger when we add weight to it: waterjet cut edge, flat edge grind, or flat edge polish, in this video.

Q: Why putting a background job into a script can make the job survive termination of the script and the caller of the script? In an interactive bash shell running inside lxterminal, if I run a background job
$ evince &

and then close the shell, the background job will be killed.
If I put the background command in a script, and run the script in an interactive bash shell:
$ cat test.sh
!# /bin/bash

evince &
$ ./test.sh
$

after the script terminates, the background job still runs. Even after I terminates the interactive bash shell, the background job still continues running.
I wonder why putting a background job into a script and running the script can make the job survive both the termination of the script and the termination of the caller of the script? Is wrapping a job into a script a good way to make the job survive the termination of the script and the termination of the shell which invokes the script?
Thanks.

A: *

*By "close the shell", I assume you mean closing the lxterminal
window. The lxterminal and the interactive bash are connected to
each other over a pseudo-TTY device, which is a kernel-level
construct.
If you do that while its interactive bash child process is still
running, the lxterminal process will close its side of the
pseudo-TTY. That causes the kernel to send a SIGHUP signal to the
interactive bash.
The SIGNALS chapter of man bash says:

The shell exits by default upon receipt of a SIGHUP. Before exiting,
  an  interactive shell resends the SIGHUP to all jobs, running or
  stopped.  Stopped jobs are sent SIGCONT to ensure that they receive
  the SIGHUP.
To prevent the shell from sending the signal to a particular job,
  it should be removed from the jobs table with the disown builtin
  (see SHELL BUILTIN COMMANDS below) or marked to not receive SIGHUP using disown -h.

The intended meaning of the SIGHUP signal is "the connection to the
user's terminal was lost; save any unsaved work if necessary, and
then exit in an orderly fashion." (For daemon processes, this is not
applicable, so for them the signal is often used to mean "reread
your configuration files" and/or "close and reopen your log files
for log rotation".)
As the man page says, the interactive bash will then resend the
SIGHUP signal to all its children (unless told otherwise using
disown). This is what causes your backgrounded evince to exit.

*But when you use a script, your interactive shell fork()s a
new process to run a shell to run the script, and then the new shell
running the script fork()s yet again to run evince. After that,
the script ends, so the shell running the script exits.
At this point, the evince process will no longer have a parent
process. But when you look at a ps -ef listing, there is never a
process with an empty PPID field: it is impossible for the process
not to have a parent. So, to deal with this situation, the kernel
assigns the orphaned evince process PPID to 1, making it the
adopted child of the init process. Now the original interactive
bash does not know that the instance of bash that ran the script
did start another process: this knowledge died along with the shell
instance that ran the script.
As a result, the interactive bash simply has no clue that there is
an evince process that might need to have SIGHUP sent to it when
the session ends.
What you've achieved with that script is actually the bare-bones
version of a technique used when intentionally daemonizing
processes, known as a double fork. (Daemonizing a process = making
it completely independent of the process and session that started
it.)
As you've seen, in practice, this is enough for making the evince
process separate from the interactive bash but still keeping it a
part of your GUI login session. But if you want a complete
daemonization, there's a few other steps you should do before the
second fork:

*

*make sure that standard input, standard output and standard error are redirected to /dev/null

*if any other file descriptors are open, close them

*cd / so that your process won't accidentally interfere with the sysadmin mounting/unmounting filesystems, unless the process
actually needs to access files in a particular filesystem

*set umask explicitly to the value you want/need it to be

*if setsid command is available, you should use it to disconnect the resulting process from your session's process group and make it
fully separate (i.e. instead of evince & at the end of your
script, you might use exec setsid evince).

See here for a more detailed description of daemonizing in bash
shell: http://blog.n01se.net/blog-n01se-net-p-145.html

A: The killing of the bacground evince it probably something in your logout profile.
using a script works because the shell that was running the the background task has already finished, you can get the same effect by typing.
( evince & )

That starts a subshell, the subshell backgrounds evince and then exits.
evince is now a daemon.

Home News Tackling global tax avoidance
Tackling global tax avoidance
New tax rules aimed at making global firms pay corporation tax bills in the jurisdiction they 'do business', have been published by the Organisation for Economic Co-operation and Development (OECD).
The proposals would scrap the century-old tax rules, and provide governments with the power to tax the big technology companies, such as Apple, Facebook and Google, who have been accused of mass tax avoidance.
The new OECD proposal, which is now open to a public consultation, would re-allocate some profits and corresponding taxing rights to countries and jurisdictions where multinational enterprises have their markets. The OECD said that it would ensure the MNEs conducting significant business in places where they do not have a physical presence are taxed, through the creation of new rules stating (1) where tax should be paid and (2) on what portion of profits they should be taxed.
OCED secretary-general, Angel Gurria, said: "We're making real progress to address the tax challenges arising from digitalization of the economy, and to continue advancing toward a consensus-based solution to overhaul the rules-based international system by 2020."

According to Fox New, Ivanka also had the number one selling fragrance on Amazon as of February 2016, the same month retailer Nordstrom dropped the brand. The spike in sales seems to be a direct response to reports of boycotts of the brand fueled by Ivanka's political association.
So, in essence, Trump supporters are making their family wealthier to prove a point to his opposers? They're…smart? We guess.

There's one in Itaewon, another in Hongdae and according to the website they're all over Seoul. They are the best only pies I've tried in Korea! They're really good so I definitely recommend giving Jesters a try. Also if you want to try the pies at home then you can buy a pack of 4 frozen for home! oh yessss!

Love Is a Many-Splendored Thing Lyrics
Love is a many splendored thing
It's the April rose
That only grows
In the early Spring
Love is nature's way of giving
A reason to be living
The golden crown that makes a man a king
Once on a high and windy hill
In the morning mist
Two lovers kissed
And the world stood still
Then your fingers touched my silent heart and taught it how to sing
Yes, true love's a many splendored thing
About "Love Is a Many-Splendored Thing"
Originally written as an instrumental to be included in Alfred Newman's score for the movie of the same title, the song was given lyrics at the request of the studio to make it eligible for the Oscar for Best Original Song. The ploy was successful, as the song won that award, defeating (among others) "Unchained Melody."

Honor has been successful so far with its line of quality but affordable smartphones and among the ones gaining popularity is their Honor Play. The Honor Play truly lives up to its name by donning powerful specs built for mobile gaming.
Compared to the other two phones I've reviewed recently, the Honor Play's exterior is much more considerate. The smudge-proof back panel and rounded edges make it easy to grip when playing a game with a landscape orientation. It also has a good weight to it, not too heavy nor too light. The width is just right and can be used with one hand. The fingerprint sensor on the back is very convenient and easy to use, allowing you to instantly unlock the phone. Though the loudspeaker was placed at the bottom, it's not easily covered when you hold the phone horizontally while playing.
Display & Multimedia
The Honor Play's 6.3-inch LCD capacitive touchscreen displays sharp images and text due to its high pixel density. It also works well with watching videos and browsing photos. Its 19.5:9 aspect ratio might not be fully optimized for some mobile games, but turning off the notch and disabling fullscreen mode can fix this. The Honor Play also has a Touch-disable mode that prevents mistaken operations when your phone is in your pocket or bag. This is pretty handy when you're on-the-go, but forgetting to turn this feature off can really disrupt your game as I've experienced when I first loaded a round of Mortal Kombat X.
As mentioned before, the speaker placement can be a bit off but it's much more tolerable than the Oppo F9. Regardless of the positioning the loudspeaker works well and can still be heard throughout an open room. It also has a 3.5mm earphone jack, perfect for when you're commuting and need something to keep you entertained.
The Honor Play is equipped with a 16MP+2MP dual rear camera and a 16MP selfie camera. Pictures turn out crisp and vivid but there are a few catches. One is that even with the AI enhancements on, the rear cameras find it hard to keep the right mix of saturation when put in bright lighting conditions. If you turn the AI off, the image ends up too desaturated. The selfie camera is also harder to use, as the local camera app doesn't allow both manual and AI adjustments and you are only left with either a small range of filters, the aggressive beautify mode, or to drop both completely.
Honor Play Sample Camera Photos:
The Honor Play really lives up to its name in terms of gameplay. I tried out the usual graphics-heavy games and found no issues while playing. Even more surprising is that it ran games better than the Oppo F9. For example, when upgrading a character in Mortal Kombat X, sometimes the game's "back" button doesn't work in the F9 and instead of returning you to the battle screen, it reloads the character stats. Here with the Honor Play, I didn't encounter this error. I also like how the local home buttons move around when you flip the phone as it always stays on the right, unlike in other phones where you need to take note which way the home buttons are located once the screen flips.
Another thing to love about the Honor Play is its screen recording feature. It can now support internal audio recording so it doesn't need to rely on the microphone anymore. The only downside to this is while recording, it will not play out the sound so you'd have to play in silence. This can be an advantage in disguise if you are recording your live narration on a separate device.
Since the Honor Play is powered by a Kirin 970 chipset, its flaws on the camera performance are quite understandable. This phone was designed with mobile gamers in mind, which makes its processor optimal for playing even the heaviest of games. Now that the GPU Turbo update is here, you can only expect for the Honor Play to do better in processing game graphics. The 6GB RAM can handle multiple tabs at the same time, so you can play more than one game at a time. I tried out waiting for my energy to refill in Mortal Kombat X, so I left the tab on and loaded Injustice 2. There were still no lags and I was able to play both games smoothly. The 3,750mAh battery capacity is large enough to last a whole day of gaming. It shouldn't come as a surprise that the Honor Play scored a benchmark of 212344 on Antutu. It even outranked the Huawei P20 Pro that's supposedly twice as expensive.
The Honor Play is truly worth raving about. It keeps up to its promise of delivering amazing speed and performance. It's definitely a great bang for your buck as it can do better than most smartphones out there with the same price tag. The Honor Play is available nationwide for a suggested retail price of Php 15,990.

I loaded Flowmotion v2.02 hack on my panasonic gh2, and from where I downloaded it, was written "Access to both PAL 25/50p and NTSC 30/60p frame rates." But in my camera I can only shoot in 24,25 and 50p. How do I shoot in 60p?


Do you by any chance have a fresh download link for that mplex MPEG muxer tool of yours?
Done. I see he's a forum member and have sent him a PM about it.
Great news that the project has now been re-activated! GUI or not, what I'd really like to see at some point is the MeGUI developers include it in the AVS Script Creator file indexing options. I guess that would come with a formal release version?
OK thanks for the advice. I dont think it is possible to upgrade the card in my laptop, but that is something to bear in mind when I eventually upgrade/replace my 'encoding' PC. Guess I'll have to continue using dss2/ffmpeg-mt for now, despite the glitches and freeze-ups.

Blood of the Wolf Begin Their "Scorched Earth Ceremony"
Ivan Belcic
Blood of the Wolf are not here to coddle hearts and caress eardrums. The all-business Chicago quartet sling a fiendishly aggressive brand of blackened death that draws as equally from their contemporaries as it does their forebears. Their upcoming sophomore full-length record II: Campaign of Extermination is a ferocious slaughter-fest that sounds exactly how a record titled "Campaign of Extermination" should.
Sit down, hold fast to a secure object, and brace yourself for our exclusive premiere of Blood of the Wolf's appropriately-titled track "Scorched Earth Ceremony."
Scraping guitars herald the doom-march of an approaching army that will stop at nothing in its remorseless pursuit of conquest. Soon, we are cast into the tumult of battle, thrashed incessantly by Rick Hernandez's machine-gun kicks and the bowel-dwelling, slime-drenched presence of vocalist and guitarist Mike Koniglio.
Blood of the Wolf blend the head-bobbing catchiness and robust vocals of Dyscarnate with retro-trebly guitar leads. Koniglio's measured delivery allows him to function as the sole anchor in the tempest of his bandmates' twitchy guitars and relentless drumming. Hernandez's head-spinning kicks are a pervasive hallmark of the band's percussive songwriting style. Even the guitar melodies hit with all the subtlety of a brass-knuckled punch to the teeth.
As their name suggests, there's nothing gentle about Blood of the Wolf. There is nary a single beat in which to stop and catch one's breath, such is the urgency of the music. From the first beat until the last, the song surges ahead at full tilt with no hesitation or wavering in purpose.
-- Ivan Belcic
Blood of the Wolf will be self-releasing II: Campaign of Extermination on April 7th. The title track is currently available for streaming on Bandcamp.

A large riding establishment/livery yard with horses used for most disciplines including cross country and show jumping would have a greater need for first aid provision than a small livery yard where staff had minimal direct contact with the horses.
Many yards will have small numbers of employees but it is still deemed necessary to have at least one first aider available at all times. For establishments covering provision to the public it would be reasonable to expect to have a first aider present at all such times.
Medi-K training offers this HSE complaint 1 day Emergency First Aid at Work Course (RQF Level 3) which will give a complete overview of first aid procedures. It is specifically designed for those who are involved in horse riding activities, including events, leisure and recreation.
Max. riders: A maximum of 12 students can be accommodated on this course and all learners must be a minimum of 14 years of age.
Assessment is on-going by the instructor,along with a multiple choice question paper,and a three year qualification will be issued to those who satisfy the criteria.
In addition,the HSE strongly recommend that all students undergo an annual refresher programme of three hours.
Courses are arranged on a day, time and at a location to suit you. The cost and time of travelling are eliminated so yard duties can be tended to during the day.
All courses are bespoke to your riding establishment, with training tailored to meet your needs whether you are a riding club, polo club, hunt club, driving or pony club.

A medication is a licenced drug taken to cure or reduce symptoms of an illness or medical condition. Medications are generally divided into two groups -- Over-the-counter drug (OTC) medications, which are available in pharmacies and supermarkets without special restrictions, and Prescription only medicines (POM), which must be prescribed by a physician. Most OTC medication is generally considered to be safe enough that most persons will not hurt themselves accidentally by taking it as instructed. Many countries, such as the UK have a third category of pharmacy medicines which can only be sold in registered pharmacies, by or under the supervision of a pharmacist. However, the precise distinction between OTC and prescription depends on the legal jurisdiction. Medications are typically produced by pharmaceutical companies and are often patented. Those that are not patented are called generic drugs.
Medication can be usually classified in various ways, e.g. by its chemical properties, mode of administration, or biological system affected. An elaborate and widely used classification system is the Anatomical Therapeutic Chemical Classification System.
Atherosclerosis/cholesterol agents: hypolipidaemic agents, statins.
A euthanaticum is used for euthanasia and physician-assisted suicide, see also barbiturates.
Polypharmacy: suggests that multiple use of prescribed and non-prescribed medications, (use of 5 or more), can have adverse effects on the recipient.
Zoopharmacognosy: Animal usage of drugs and non-foods.


These were aspects of life worthy of chasing when I was younger. Much younger than I am now.
My feelings at the time were, If I had any of these, then life would be sweet.
I have always had a desire to live a life on my own terms. I always looked at fame and fortune as a gateway to a life, a sweet life full of champagne, parties and every day being fun.
This did not reflect the reality of my life. The reality was working for someone else with deadlines. Having mountains of work unfinished that spill into the next day. A perception of a continuous stream of needing to satisfying customer needs. A reality that I grew into, not being the reality I wanted for this life. It was strange, I always 'felt' I had an entrepreneurial spirit. Even in high school thought that 'entrepreneurs' were those smart kids who bucked the system. I thought they left high school early because they were a bloody genius. These entrepreneurs were driven and didn't need to attend college, because they were too cool for school. I know that reality and my understanding of an entrepreneur to be different now.
But what I wanted was more of a life on my own terms. To take a holiday for a week when I wanted to. To take my daughter to kindergarten, because I had the time to. To work more when I wanted at a time of day of my choosing, or to decide the number of days I wanted to work.
It has taken a long time to realise that my journey brings me to this point of why I started and maintain this blog. It's main purpose it to provide value. Value in showing someone from a video how to get going on Twitter for their business. Then using Twitter to start effective communication with their customer base. Value in demystifying Snapchat for an older generation who come to realise it's a great platform. Discovery telling a 10 second video story, which may lead to that person to discover live streaming is in their business future. Value in someone reading an article. They send me an email saying 'I just wanted to know the basics of WhatsApp was and your article helped me understand, Thankyou'. Value in giving enough information to help so when people come to my blog with a burning question they come away with an answer. To allow an arena to make a difference in people's lives no matter how small.
It' s to embrace that entrepreneurial spirit and see where I may take this blog on it's journey. I see this blog transforming into a full time business and transition out from my current employed 9 – 5. My intent is to go from a (hobby) blog to one with a full repository of information with articles, videos and audio. There will also be courses, ebooks, webinars, a podcast and live workshops. Much of what will appear over time here, will also be shaped by you. You the reader and your feedback will steer the direction of how I can best help on your information journey. For me being an entrepreneur is not only about being away from the 9-5 and define my own destiny. It will also providing relevant products or services to sell + customers = business.
The path I take for providing a product or service and how I serve my customers is important to me. The time I choose to spend to build and run a business is important to me. I have experience and a love of sharing tech with other that I am sure will be a great value proposition for many of you.
To make some money – Running a blog costs money. Domain registrations, purchasing WordPress plugins, email servers and many other factors. Even when your articles, ebooks, videos and podcasts you create and produce are 'free', they need to live on your blog and it costs money to do so.
To build a tribe – To help those who have burning questions on using apps and don't know where to go to get answers. Over time people will come to the blog to have their questions answered or even email me with a question. Once a certain concept has become understood then my tribe can take their understanding of using an app to the next level.
To provide value – To create and give information that's useful. To ensure I provide informative, relevant, helpful information and teach people. To take them on a journey from not understanding a concept or app. Then they ask a question to me providing them with help and getting the answers they need.
To grow and learn myself – To fail and fail often and to learn from that and grow. Over time I will come to know 'my people' and how I can best serve their needs. To also put my mark and personality and style on the blog that separates me from those that are in a similar niche to me. I don't see those in this niche to be competitors. I see them as collaborators that can create awesome stuff more so than creating on one's own.
So, having a burning question about an app? Look through the blog and if you don't find what you need, drop me an email and I will answer your question.
Thankyou for joining me on this journey.
Welcome to the blogging world and I do hope you make it big.
I will be looking forward to your tribe and your will be a part of it soon.
Thanks for stopping bye and saying hi, enjoyed reading your article on She Me Loud!

DENIED: Binance Blocks Relatives of Senior Russian Officials
The world's largest cryptocurrency trading platform warned that the sanctions against Russia could mean tougher checks on people trying to buy from its system.
Digital asset exchange, Binance blocks trading accounts tied to relatives of government officials in Moscow, including children of Top Russian Figures.
Bloomberg reports that several accounts linked to high-ranking members of Russian President Vladimir Putin's administration have been blocked by Binance, the world's leading crypto exchange.
Sanctions are continuing to fall on Russia over its military assault on its neighboring country, Ukraine. Some believe that this move was put into place to hurt the Russian economy.
The stepdaughter of Foreign Minister Sergei Lavrov, Polina Kovaleva, and the daughter of the Kremlin Spokesperson are among the few that have been denied access in the past two months since Russian troops crossed the Ukrainian border.
Kirill Malofeev, son of Russian billionaire Konstantin Malofeev, was also banned after being accused by the US of funding pro-Russian rebels. Malofeev, who is a Putin supporter, has been on the U.S. and EU sanctions list for years due to his involvement in the war in the Donbas region.
The news of the limited accounts comes after an earlier announcement in April where Binance curbed its services to Russian users to comply with the latest round of sanctions approved by the European Union. Russian nationals, residents, and legal entities that have more than €10,000 ($10,800) in value have been subject to the restrictions.
In early March, Binance CEO Changpeng Zhao said that the exchange was freezing the accounts of Russians who had already been hit by sanctions, but that blocking all Russians would be considered "unethical".
Yesterday, Changpend Zhao tweeted that it blocked Peskova on March 3, upon attempting to use the exchange through a third-party brokerage. She was later sanctioned by the U.S. Treasury Department the following week.
Poyraz said that Binance blocked Peskova on March 3, when she tried to use the exchange through a third-party brokerage. She was then sanctioned by the U.S. Treasury Department on March 11.
Against war, not the people.
https://t.co/rRDdFRTrTR
— CZ 🔶 Binance (@cz_binance) April 29, 2022
Kovaleva's account was closed on March 24, the day she was sanctioned by the U.K. Malofeev was designated by the U.S. Treasury on April 20, and had his Binance accounts restricted this week, the company added.
Chagri Poyraz, the platform's global head of sanctions assured that the exchange will continue its efforts to identify other people connected to sanctioned individuals. Stating:
"What's different is that our compliance screen operations are 'proactive,' aiming to detect and deter financial crime risk before any regulatory or legal action towards these individuals or entities."

Inflation is Killing the Poor. Amazon Founder, Jeff Bezos Blasts the Biden Administration Over Comments on Inflation in a Tweet on Sunday.
Inflation is killing the poor.
President Joe Biden was criticized for the second time this week for his comments on inflation by Amazon founder Jeff Bezos, who said on Sunday that inflation is most harmful to the least affluent in the United States.
"In fact, the administration tried hard to inject even more stimulus into an already over-heated, inflationary economy and only Manchin saved them from themselves," Bezos wrote on Twitter. "Inflation is a regressive tax that most hurts the least affluent. Misdirection doesn't help the country."
The comments from Bezos were in response to a thread in which President Joe Biden claimed the US was on track to see its largest yearly deficit, totaling $1.5 trillion.

— Jeff Bezos (@JeffBezos) May 15, 2022
Is Inflation Slowing Down?
According to data recently released by the U.S. Bureau of Labor Statistics, consumers' prices rose less than expected last month. The Consumer Price Index for All Urban Consumers (CPI-U) is a measure of the average change over time in the prices paid for a market basket of consumer goods and services.
The year-over-year increase in the consumer price index was 8.3% in April, not adjusted for seasonal factors, compared to historic increases in February and March.
The spike in the inflation rate in March was the greatest in more than three decades, where the CPI rose 8.5 percent. Prices reached historic highs in February 2022, with inflation rising by 7.9 percent.
The numbers in April didn't shatter any records, however. Real estate, gas, food, airline fares, and new vehicles are some of the items that are hurting American pocketbooks due to inflation.

Taxing the Wealthy
On Friday, Bezos called out President Biden for suggesting that taxing wealthy corporations could lower inflation, urging a newly formed Disinformation Board to take a look at the statement.
"Raising corp taxes is fine to discuss," Bezos wrote on Friday.
"Taming inflation is critical to discuss. Mushing them together is just misdirection."
Comments from both President Biden and Bezos come as mass corporate layoffs hit numerous industries.
As of March, roughly 64.4 percent of American families, or 166 million adults, reported they were living paycheck to paycheck, according to research by LendingClub and PYMNTS.
Fed: ISO 20022 Reserve Banks to Globally Merge Cash Transfer Regs
ISO 20022 Standards will enhanced efficiency of domestic and global payments that may help banks and other entities with sanctions and AML requirements.
Fed Announces that Reserve Banks will adopt ISO 20022 Standards
Current banking language makes it difficult to efficiently process wire transfers globally.
ISO 20022 compliant cryptos include Bitcoin, Iota, and Algorand.
On Monday, May 2, 2022, the Federal Reserve Board announced that Federal Reserve Banks will adopt the ISO® 20022 message format for the Fedwire® Funds Service.
According to a press release by the Federal Reserve, this new format will allow for an "enhanced efficiency of both domestic and cross-border payments, and a richer set of payment data that may help banks and other entities comply with sanctions and anti-money laundering requirements."
Virginia Senate Passes Bill Allowing State Banks to Offer Crypto Services
ISO 20022 was presented by the organization as a means of developing communication between financial institutions. The new standards propose that it will make financial transactions more efficient, unlike today's standards. Currently, banking institutions are using their own programming languages, making it difficult to transfer funds internationally.
The ISO 20022 was developed by the International Organization for Standardization, an independent, non-governmental organization that addresses and issues standards for a wide range of industries, including financial institutions.
The revised plan for migrating the Fedwire Funds Service to the new message format was invited for public comment by the Board, saying:
Comments are due 90 days after publication in the Federal Register, which is expected shortly.
The Board wants the Reserve Banks to adopt the new message format on a single day instead of in three separate phases as previously proposed.
Cryptocurrencies to keep an eye on that are compliant with ISO 20022 proposed messaging standards include: Bitcoin (CCC:BTC-USD), XDC (CCC:XDC-USD), Iota (CCC:MIOTA-USD), and Algorand (ALGO-USD).

Ripple (CCC:XRP-USD), and Stellar Lumens (CCC:XLM-USD) are not only ISO 20022-compliant, but they are also members of the ISO 20022 Standards Body, according to the Registration Management Group Member List website.
The Fedwire Funds Service is a real-time gross settlement system that's owned and operated by the Federal Reserve Banks.
It allows businesses and financial institutions to transfer funds quickly and securely, and it's a vital tool for the global economy.
Gov. Newsom Issues Executive Order on Crypto and Blockchain
Governor Newsom Issues Executive Order allowing California to assess using blockchain technology in state operations – DEEDE News Media
Governor Gavin Newsom issues executive order on blockchain aligns with the Biden administration proposal in March.
The governor is calling on the state of California to look into using the technology in state operations.
California aims to create a transparent and consistent business environment for companies operating in Web3.
Over the course of a decade, tech investors and businesses in California have bet on the future of digital currency. Just recently, the governor of the State with the largest economy is now a part of the movement.
On Wednesday, the Governor of California, Gavin Newsom issued an executive order on cryptocurrencies, laying out a road map for regulatory and consumer protections and examining ways the state can take advantage of the technology.
This comes as the Senate of the State of Virginia passes House Bill 263, allowing state banks to participate in the services of cryptocurrencies.
Senior advisor to Newson, Dee Dee Myers, tells CNBC:
Of the 800 blockchain businesses in North America, about a quarter of them are in California, dramatically more than any other state. We've heard from so many that they want to be here, and we want to help them do that responsibly.
The goal of the order is to create a transparent and consistent business environment for companies that are operating in Web3 technologies. New regulatory frameworks for companies that operate in California will also be helped by this.
Agencies within the Newson administration are required to submit their findings and recommend next steps.
According to the order, it will "reflect consultation with relevant state agencies regarding the forthcoming federal reports on the relationship of crypto assets to priorities in energy, climate, and preventing criminal activity."
Myers said the agencies plan to hold roundtables and listening sessions with industry leaders, consumer advocates, and even critics.
The White House is in the process of economic reform and new legislation continues to be introduced almost daily. With cities like Miami aiming to become the "Wall Street of Cryptocurrencies," we may see a spike in adoption much sooner than expected.
Currently, there are over 30 States drafting legislation in support of Biden's Executive Order, which addresses the responsible development of digital assets.
