Interactions between bacteria and the viruses that infect them (i.e., phages) have profound effects on biological processes, but despite their importance, little is known on the general structure of infection and resistance between most phages and bacteria. For example, are bacteria-phage communities characterized by complex patterns of overlapping exploitation networks, do they conform to a mo...

There is a biomedical need to develop molecular recognition systems that selectively target the interfaces of protein and lipid aggregates in biomembranes. This is an extremely challenging problem in supramolecular chemistry because the biological membrane is a complex dynamic assembly of multifarious molecular components with local inhomogeneity. Two simplifying concepts are presented as a fra...

Upon infection, cellsof higher vertebratesproduce interferons (IFNs),whichactivate variousantiviral programs in the infectedcell andsurroundingcells, thus limiting the spreadof infection.Oneof these antiviral mediators is RNase L, an endoribonuclease that cleaves viral and cellular RNA on demand. RNase L is activated by 2’,5’-linked oligoadenylates (2-5A), products of IFN-inducible 2-5A synthet...

This paper deals with the system composed by a rigid ball moving into a viscous incompressible fluid, over a fixed horizontal plane. The equations of motion for the fluid are the Navier–Stokes equations and the equations for the motion of the rigid ball are obtained by applying Newton’s laws. We show that for any weak solution of the corresponding system satisfying the energy inequality, the ri...

The status of the measurements and the theoretical developments concerning the hadronic structure of the photon are briefly summarised.

activity and a wide spectrum against both Gram-positive and Gram-negative bacteria1~4). This high activity is due to good diffusion through the outer membranein Gram-negative organisms5), high affinities for penicillinbinding proteins (PBPs)6'7) and high stability and inhibitory activity against /Mactamases8). However, carbapenems were hydrolyzed by dehydropeptidase-I (DHP-I) from several anima...

Perception of segregated sources is essential in navigating cluttered acoustic environments. A basic mechanism to implement this process is the temporal coherence principle. It postulates that a signal is perceived as emitted from a single source only when all of its features are temporally modulated coherently, causing them to bind perceptually. Here we report on neural correlates of this proc...

We study the interactions of the octet baryons in a relativistic meson exchange approach connecting freespace and in-medium interactions with those in finite (hyper)nuclei. Our approach is based on the covariant meson exchange framework. To generate the effective microscopic interaction in finite nuclei an approach using Tmatrix theory with a three dimensionally reduced twonucleon propagator is...
