background: every year many organizations formulate a code of ethics (coe) but when it comes to implementing, it does not achieve the desired purposes. ineffectiveness of coes can stem from different factors and surely, one of them is bad formulation. this research was conducted to identify the barriers to effective formulation of coes in one of the main state universities of medical sciences i...

We present the first observation of incoherent antidark spatial solitons in noninstantaneous nonlinear media. This new class of soliton states involves bright solitons on a partially incoherent background of infinite extent. In the case where the nonlinearity is of the Kerr type, their existence is demonstrated analytically by means of an exact solution. Computer simulations and experiments ind...

Fresnel Incoherent Correlation Holography (FINCH) enables holograms to be recorded from incoherent light with just a digital camera and spatial light modulator. We previously described its application to general three dimensional incoherent imaging and specifically to fluorescence microscopy, wherein one complex hologram contains the three dimensional information in the field of view, obviating...

In neutron scattering by C2CI6 the incoherent contribution to the quasielastic linewidth gives information on the reorientational motion of the molecules by scattering on individual atoms. The coherent scattering contains in contrast also interference effects. With polarisation analysis it is possible to distinguish between coherent and spin incoherent scattering. If it is possible to modulate ...

We show that for the half-filled Kondo lattice model on honeycomb a breakdown occurs at small couplings $J_k$ within magnetically ordered phase. Our conclusions are based auxiliary field quantum Monte Carlo simulations of so-called composite fermion spectral function. Within U(1) gauge theory formulation model, it becomes apparent Higgs mechanism dictates weight resonance in For we observe quas...

We report the observation of modulational instability (MI) of a partially spatially incoherent beam induced by seeding noise through cross-phase modulation. We show experimentally that a threshold exists for such induced incoherent MI to occur that depends on the degree of spatial coherence as well as on the strength of the nonlinearity. Above threshold, the induced MI leads to the formation of...
