Ready to replicate? So vesiculate!
ells that passively swell and contract with changes in osmolarity are the key to detecting those changes, say Most cells have at least two mechanisms for maintaining homeostasis in response to changes in salt concentrations. Without these mechanisms, osmotic forces take over: more water and thus less salt outside cells leads water to flood into a cell. But this swelling doesn't occur in most ce...
متن کاملIncubation time to crazing in stressed poly(methyl methacrylate)
Crazing is usually a precursor of the brittle fracture of glassy polymers. In this paper, an optical technique is presented to quantify the crazing dominated creep damage that occurs on a stressed transparent glassy polymeric sheet of polymethyl methacrylate (PMMA). The specimens, with various sections, are loaded for a predefined period of time under a constant load at room temperature, and th...
متن کاملCells lacking glycan phosphatidylinositol-linked proteins have impaired ability to vesiculate.
Erythrocytes shed membrane vesicles in response to many stimuli. It has been previously demonstrated that glycan phosphatidylinositol-linked (GPI-linked) proteins such as decay accelerating factor and acetylcholinesterase are concentrated in these vesicles relative to the erythrocyte membrane. We have examined the requirement for GPI-linked proteins for the process of vesiculation. Erythrocytes...
متن کاملMetarecognition in Time-Stressed Decision Making: Recognizing, Critiquing, and Correcting
We describe a framework for decision making, called the Recognition/Metacognition (R/M) model, that explains how decision makers handle uncertainty and novelty while at the same time exploiting their experience in real-world domains. The model describes a set of critical thinking strategies that supplement recognitional processes by verifying their results and correcting problems. Structured si...
متن کاملHuman-Agent Collaboration for Time-Stressed Multicontext Decision Making
Multi-context team decision making under time stress is an extremely challenging issue faced by various real world application domains. In this study we employ an experience-based cognitive agent architecture (R-CAST) to address the informational challenges associated with military command and control (C) decision making teams, the performance of which can be significantly affected by dynamic c...
