Experimental investigation of hydrodynamics of melt layer during laser cutting of steel [PDF]
, 2011 In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front in the case of laser cutting of

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

A Proximal Analytic Center Cutting Plane Algorithm for Solving Variational Inequality Problems
Journal of Applied Mathematics, 2012 Under the condition that the values of mapping F are evaluated approximately, we propose a proximal analytic center cutting plane algorithm for solving variational inequalities. It can be considered as an approximation of the earlier cutting plane method,

A nontangential cutting plane algorithm
Operations Research Letters, 2002 The author examines the cutting plane algorithm for solving the Lagrangian dual problem of a convex program. This paper demonstrates that the algorithm still converges to an optimal solution when cuts are nontangential or generated by not solving the optimality or nearly so. Computational results from randomly generated linear and quadratic programming
