For M-theory on the G 2 holonomy manifold given by the cone on S 3 × S 3 we consider the superpotential generated by membrane instantons and study its transformations properties, especially under monodromy transformations and triality symmetry. We find that the latter symmetry is, essentially, even a symmetry of the superpotential. As in Seiberg/Witten theory, where a flat bundle given by the p...

Giant vesicles (GVs) encapsulating colloidal particles by a specific volume fraction show a characteristic configuration under a hypertonic condition. Several flat faces were formed in GV membrane with orderly array of inner particles. GV shape changed from the spherical to the asymmetrical polyhedral configuration. This shape deformation was derived by entropic interaction between inner partic...

Flexible IR Imaging Photodetectors In article number 2300159, Jinzhong Wang, Shiyong Gao, and co-workers, successfully prepared, a large-area freestanding Bi2S3 nanofibrous membrane (NFM) with high flexibility, which is self-assembled from ultralong nanowires. The flexible photodetector based on the as-prepared NFM exhibits responsivity, fast response, excellent stability splendent imaging capa...

introduction: flat foot is one of the most common disorders which not only influences the performance of the foot, but also affects the alignments of the ankle, knee and hip joints. the performance of flat arched differs from that of normal subjects during walking. however, there is not enough information in the literature regarding the difference between standing stability. moreover, the influ...

Members of the Arf family of small G proteins are involved in membrane traffic and organelle structure. They control the recruitment of coat proteins, and modulate the structure of actin filaments and the lipid composition of membranes. The ADP-ribosylation factor 6 (Arf6) isoform and the exchange factor for Arf6 (EFA6) are known to regulate the endocytic pathway of many different receptors. To...

Diffusion of particles in curved surfaces is inherently complex compared with diffusion in a flat membrane, owing to the nonplanarity of the surface. The consequence of such nonplanar geometry on diffusion is poorly understood but is highly relevant in the case of cell membranes, which often adopt complex geometries. To address this question, we developed a new finite element approach to model ...

In 2001, S. Bulman-Fleming et al. initiated the study of three flatness properties (weakly kernel flat, principally weakly kernel flat, translation kernel flat) of right acts $A_{S}$ over a monoid $S$ that can be described by means of when the functor $A_{S} otimes -$ preserves pullbacks. In this paper, we extend these results to $S$-posets and present equivalent descriptions of weakly kernel p...

The present work aims to study the possibility of utilization a forward osmosis desalination process as an alternative method extract water from brine solution rejected reverse process. Experiments conducted in laboratory–scale (FO) unit cross flow flat sheet membrane cell yielded flux ranging (0.0315 0.56 L/m2 .min) when using CTA membrane,and (0.419 2.785 for PA under 0.4 bar. Two possible or...

A lab-scale ceramic membrane bioreactor (MBR) with active membrane-fouling control system was developed for the partial nitrification (PN) process. The in situ cleaning method applied to remove contaminants on surface of no interruption wastewater treatment. results showed that device increased critical flux and reduced gel layer resistance (Rg) internal (Ri) flat-sheet by inhibiting formation ...

The interaction of an acoustic wave with two joined flat plates results in a diffracted acoustic wave emanating from the junction. The plates are assumed, for simplicity, to have different masses but no stiffness, and the exact solution of the two-dimensional diffraction problem is derived as a Fourier integral. The diffraction coefficient for a plane acoustic wave is found to depend in a simpl...
