We compute exactly the average spatial density for $N$ spinless noninteracting fermions in a $2d$ harmonic trap rotating with constant frequency $\mathrm{\ensuremath{\Omega}}$ presence of an additional repulsive central potential $\ensuremath{\gamma}/{r}^{2}$. find that large-$N$ limit, bulk has rich and nontrivial profile---with hole at center surrounded by multilayered ``wedding cake'' struct...

background t-helper (th) lymphocyte cytokine production may be important in the immune pathogenesis of hepatitis c virus (hcv) infections. th1 cytokines such as; interleukin- 2 (il-2), and interferon gamma (ifn-gamma) are necessary for host antiviral immune responses, while th2 cytokines (il-4, il-10) can inhibit the development of these effector mechanisms. objectives the aim of the present st...

GRB fireballs could be ensheathed by a relativistic, baryon-enriched outflow that would in selected directions scatter a polarized beam of gamma rays. The strong polarization recently announced by RHESSI is attainable by the scattering mechanism, though not most of the time. The scattering mechanism, when acting in addition to the synchrotron mechanism, could circumvent some of the predictions ...

Neuroimaging studies have reported greater activation of the human amygdala in response to faces than to nonfacial stimuli, yet little is known about the temporal profile of this activation. We investigated this issue by recording the intracranial field potentials of the amygdala in participants undergoing preneurosurgical assessment (n = 6). Participants observed faces, mosaics, and houses in ...
