A bstract Swampland criteria like the Weak Gravity Conjecture should not only apply to particles, but also other lower-codimension charged objects in 4d EFTs strings and membranes. However, description of latter is general subtle due their large backreaction effects. In context $$ \mathcal{N} N = 1 EFTs, we c...

background: guided tissue regeneration (gtr) allows mesenchymal cells to repopulate the defects. however, there is limited information regarding the effi cacy of different membranes. the present study was designed to histologically and histomorphometrically compare three collagen membranes in regenerative treatment of dehiscence defects in dogs. materials and methods: this 8 weeks experimental ...

Salinity gradient energy is a prominent alternative and maintainable source, which has considerable potential. Reverse electrodialysis (RED) one of the most widely studied methods to extract this energy. Despite progress in research, optimization RED process still ongoing. In study, effects number membrane pairs, ratio salinity feed velocity on power generation via reverse system were investiga...

The fluctuation pressure of a lipid-bilayer membrane is important for the stability of lamellar phases and the adhesion of membranes to surfaces. In contrast to many theoretical studies, which predict a decrease of the pressure with the cubed inverse distance between the membranes, Freund suggested very recently a linear inverse distance dependence [Proc. Natl. Acad. Sci. USA 110, 2047 (2013)]....

Fast synchronous neurotransmitter release is triggered by calcium that activates synaptotagmin-1 (syt-1), resulting in fusion of synaptic vesicles with the presynaptic membrane. Syt-1 possesses two Ca(2+)-binding C2 domains that tether membranes via interactions with anionic phospholipids. It is capable of crosslinking membranes and has recently been speculated to trigger fusion by decreasing t...

We have used a lamellar phase made of a nonionic surfactant, dodecane and water, as a model membrane to investigate its interactions with macromolecular inclusions bringing together two membranes, i.e., acting as macromolecular snaps. In systems devoid of inclusions, the interlamellar distance depends on the total volume fraction of membranes Phi. We show that, in presence of a transmembrane pr...

The rate of lateral diffusion of proteins over micron-scale distances in the plasma membrane (PM) of mammalian cells is much slower than in artificial membranes [1, 2]. Different models have been advanced to account for this discrepancy. They invoke either effects on the apparent viscosity of cell membranes through, for example, protein crowding [3, 4], or a role for cortical factors such as ac...

We discuss the proposed description of configurations with fourbranes and six-branes in m(atrix) theory. Computing the velocity dependent potential between these configurations and gravitons and membranes, we show that they agree with the short distance string results computed in type IIa string theory. Due to the “closeness” of these configuration to a supersymmetric configuration the m(atrix)...

a  new  type  of  cation-exchange  nanocomposite  membranes  was prepared  by  in-situ  formation  of  zno  nanoparticles  in  a  blend containing  sulfonated  poly  (2,6-dimethyl-1,4-phenylene  oxide)  and sulfonated polyvinylchloride  via  a  simple  one-step  chemical method.  as-synthesized  nanocomposite  membranes were characterized  using  fourier  transform  infrared  spectroscopy, scan...
