The shuttle effect induced by soluble lithium polysulfides(LiPss)is known as one of the crucial issues that limit the practical applications of lithium-sulfur(Li-s)***,a titanium dioxide nanoparticle embedded in nitrogen-doped porous carbon nanofiber(TiO_(2)@NCNf)composite is constructed via an interface-induced polymerization strategy to serve as an ideal sulfur *** the protection of the nanofiber walls,the uniformly dispersed TiO_(2) nanocrystalline can act as capturing centers to constantly immobilize LiPss towards durable sulfur ***,the mesoporous microstructure in the fibrous framework endows the TiO_(2)@NCNf host with strong physical reservation for sulfur and LiPss,sufficient pathways for electron/ion transfer,and excellent endurance for volume *** expected,the sulfur-loaded TiO_(2)@NCNf composite electrode presents a fabulous rate performance and long cycle lifespan(capacity fading rate of 0.062%per cycle over 500 cycles)at 2.0 ***,the assembled Li-s batteries harvest superb areal capacity and cycling stability even under high sulfur loading and lean electrolyte conditions.

Using e^(+)e^(−)annihilation data corresponding to an integrated luminosity of 2.93 fb^(−1)taken at the center-of-mass energy√s=3.773 GeV with the BesIII detector,a joint amplitude analysis is performed on the decays D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η).The fit fractions of individual components are obtained,and large interferences among the dominant components of the decays D^(0)→a_(1)(1260)π,D^(0)→π(1300)π,D^(0)→ρ(770)ρ(770),and D^(0)→2(ππ)_(s)are observed in both *** the obtained amplitude model,the CP-even fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are determined to be(75.2±1.1_(stat).±1.5_(syst.))%and(68.9±1.5_(stat).±2.4_(syst.))%,*** branching fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are measured to be(0.688±0.010_(stat.)±0.010_(syst.))%and(0.951±0.025_(stat.)±0.021_(syst.))%,*** amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D^(0)→4πwhen used to determine the CKM angleγ(ϕ_(3))via the B^(−)→DK^(−)decay.

利用意大利Legnaro实验室串列静电加速器提供的65 MeV13C束流与122sn靶的熔合蒸发反应布居了131Ba的高自旋态，并搭建了新的能级纲图。新的能级纲图由15条转动带组成，包括三对手征双重带，其中两对正宇称手征带为赝自旋-手征四重带。正负宇称手征带通过一系列增强的e1跃迁连接，表明它们之间存在八极关联。在低自旋区域搭建了一条新的转动带，通过一系列γ跃迁向νh11/2晕带退激。这种能级结构与摇摆带相似，但基于现有的实验证据还难以将它确认为摇摆带，不能排除其它集体激发机制，如γ振动的影响。

本文介绍群体饲养生命表的资料分析基本原理及转换为个体生命表的方法。群体饲养生命表的记录实际上即年龄-龄期两性生命表的N矩阵,而每日所有雌虫的总繁殖记录即为ftotal矩阵。利用N矩阵与ftotal矩阵可以计算s矩阵、f矩阵及各种群参数。以桃蚜Myzus persicae和马铃薯块茎蛾Phthorimaea operculella为例,阐明群体饲养生命表分析的理论依据,证明群体饲养生命表得到的各项参数可靠,并介绍了一种将群体饲养生命表转化为个体生命表的方法。比较了群体饲养生命表和个体饲养生命表的特点。利用群体饲养研究昆虫生命表可以节省大量人力、时间与经费,群体饲养生命表可用于设计大量饲养生物防治天敌、鱼与鸟的饲料昆虫以及可供人类食用的昆虫。
