We investigate the Gouy phase shift for full-aperture waves converging to a focal point from all directions in two and three dimensions. We find a simple interpretation for the Gouy phase in this situation and show that it has a dramatic effect on reshaping sharply localized pulses.

We investigate theoretically a surface plasmon transport in the metal nanowire coupling to a pair of quantum dots. The Fano-type transmission spectrum is analyzed. The phase shift and group velocity delay of the transmitted surface plasmon are explored. The electromagnetically-induced-transparency-type transmission spectrum is also discussed.

Extensive efforts have been devoted to developing electron donor-acceptor systems that mimic the utilization of solar energy that occurs in photosynthesis. X-ray crystallographic analysis shows how absorbed photon energy is stabilized in those compounds by structural changes upon photoinduced electron transfer (ET). In this study, structural changes of a simple ...

A N-O bond is introduced into hyperbranched polyimide photocatalysts for the first time to change their polarity and modulate electronic structure. Both of the changes help improve the photocatalytic ability of the polyimide. This strategy shows great prospect for synthesizing effective organic photocatalysts.

Ruxolitinib, a selective inhibitor of Janus kinase (JAK) 1 and 2, has clinically significant activity in myelofibrosis. In this double-blind trial, we randomly assigned patients with intermediate-2 or high-risk myelofibrosis to twice-daily oral ruxolitinib (155 patients) or placebo (154 patients). The primary end point was the proportion of patients with ...

Secondary hyperparathyroidism (SHPT) is associated with poor outcome including mortality, hospitalization, as well as greater healthcare resource utilization and costs in chronic kidney disease (CKD). We hypothesized that SHPT is also associated with poor self reported health-related quality of life (HRQOL) in prevalent hemodialysis (HD) patients. We conducted a case-control ...

We study the spiral spectra scattered off transparent dielectric spheres when probed by different Laguerre-Gaussian light beams, carrying nested topological wavefront dislocations. We show that such scattering data may be employed to determine geometrical properties of the spheres, such as their position. The technique is a generalization of standard Mie ...

A significant portion of newly synthesized protein fails to fold properly and is quickly degraded. These defective ribosomal products (DRiPs) are substrates for the ubiquitin-proteasome system (UPS) and give rise to a large fraction of peptides presented by major histocompatibility complex class I molecules (MHCI). Here, we showed that DRiPs ...

Sialic acids are terminal acidic monosaccharides which influence the chemical and biological features of glycoconjugates. Their removal catalyzed by a sialidase modulates various biological processes through change in conformation and creation or loss of binding sites of functional molecules. Sialidases exist widely in vertebrates and also in a variety of ...
