Superconductivity and superfluidity as universal emergent phenomena

引用

Frontiers of physics 2015年第4期10卷 67-72页

作者： mike Guidry Yang Sun Department of Physics and Astronomy University of Tennessee Knoxville Tennessee 37996 USA Department of Physics and Astronomy Shanghai Jiao Tong University Shanghai 200240 China IFSA Collaborative Innovation Center Shanghai Jiao Tong University Shanghai 200240 China State Key Laboratory of Theoretical Physics Institute of Theoretical Physics Chinese Academy of Sciences Beijing 100190 China

Superconductivity （SC） or superfluidity （SF） is observed across a remarkably broad range of fermionic systems： in BCS, cuprate, iron-based, organic, and heavy-fermion superconductors, and in superfiuid helium-3 in condensed matter; in a variety of SC/SF phenomena in low-energy nuclear physics; in ultracold, trapped atomic gases; and in various exotic possibilities in neutron stars. The range of physical conditions and differences in microscopic physics defy all attempts to unify this behavior in any conventional picture. Here we propose a unification through the shared symmetry properties of the emergent condensed states, with microscopic differences absorbed into parameters. This, in turn, forces a rethinking of specific occurrences of SC/SF such as high-To SC in cuprates, which becomes far less mysterious when seen as part of a continuum of behavior shared by a variety of other systems.

riding the rails-different modes for rNA complex transport in axons

Neurons are highly polarized cells with axons that innervate distant *** distance of subcellular compartments from the nucleus requires sophisticated transport mechanisms and local action of vital processes for proper function and rapid responses to local stimuli(Terenzio et al.,2017).This is partially achieved by transport of mrNAs to subcellular locations and regulation of local translation for axonal growth,branching,synaptic plasticity,and regeneration,among other *** synthesized proteins support neuronal survival,and axonal development,maintenance,and growth(rishal and Fainzilber,2014;Dalla Costa et al.,2021).Thus,understanding the mechanisms that promote rNA transport to subcellular locations in neurons will contribute to the development of novel strategies to enhance axon regeneration and survival.

Prioritizing lung-protective ventilation has produced a clear mortality benefit in neonates with congenital diaphragmatic hernia(CDH).While there is a paucity of CDH-specific evidence to support any particular approach to lung-protective ventilation,a growing body of data in adults is beginning to cl.rify the mechanismsbehind ventilator-induced lung injury and inform safer management of mechanical ventilation in *** review summarizes the adult data and attempts to relate the findings,conceptually,to the CDH *** lessons from the adult studies are that much of the damage done during conventional mechanical ventilation affects normal lung tissue and that most of this damage occurs at the low-volume and high-volume extremes of the respiratory ***,it is important to prevent atelectasis by using sufficient positive end-expiratory pressure while also avoiding overdistention by scaling tidal volume to the amount of functional lung tissue rather than body *** early in acute respiratory distress syndrome improves outcomes,possibly because consistent respiratory mechanics facilitate avoidance of both atelectasis and overdistention—a mechanism that may also apply to the CDH ***-targeted conventional modes may be advantageous in CDH,but determining optimal tidal volume is *** high-frequency oscillatory ventilation and high-frequency jet ventilation have been used successfully as'rescue modes'to avoid extracorporeal membrane oxygenation,and a prospective trial comparing the two high-frequency modalities as the primary ventilation strategy for CDH is underway.
