We propose experimental measurements of the logarithmic negativity, which quantifies quantum correlations using Gouy phase in an asymmetric double-slit interference experiment for twin photons. This is possible because both quantities have analogous dependence with spatial confinement by slits and enables one to manipulate portion entanglement phase. In order obtain those measurements, we need ...

The modified $F(R)$ gravity theory with the function $F(R)=-(1/\beta)\ln(1-\beta R)$ is studied. action at small coupling $\beta$ becomes Einstein--Hilbert action. bound on parameter from local tests $\beta\leq 2\times 10^{-6}$ cm$^2$. We find constant curvature solutions and it was shown that de Sitter space unstable but a solution zero Ricci scalar stable. potential mass of field (scalaron) a...

Bacterial cells in the logarithmic phase of growth are characterized by an ability to reproduce in fresh media without the initial lag period required by organismns in later phases of development. It would seem that the latter lack certain chemical or physiological properties prerequisite to cell division. The type of changes taking place during what may be called the rejuvenation of the cell h...

Background: Cutaneous leishmaniasis is one of the most important parasitic diseases in humans. In this disease, one of the responsible organisms is Leishmania major, which is transmitted by sandfly vector. There are specific differences in biochemical profiles and metabolite pathways in logarithmic and stationary phases of Leishmania parasites. In the present study, 1H NMR spectroscopy was used...

OBJECTIVE The impact of anaerobic growth conditions on the Staphylococcus aureus toxic shock syndrome toxin-1 (TSST-1) production was studied. METHODS Ten strains of S. aureus derived from patients with toxic shock syndrome (TSS), 10 isolates of S. aureus, and documented TSST-1-producing strains recovered from patients with either staphylococcal septicemia or staphylococcal nongenital abscess...
