2Diversity, Endemism and Conservation of Ferns(Polypodiales) in the Mexican Mountain Component显示文摘We analyzed the distributional patterns of95 selected species of leptosporangiate ferns inhabiting the Mexican Mountain Component, using grid-cells of one geographical degree as unit areas,applying endemism indices and richness and beta diversity analyses.Distributional data were obtained from several herbaria and specialized literature.Five grid-cells appear to be important for fern species richness, as they contain 35 to 49 species.These gridcells are located in the Sierra Madre Oriental(SMO),Trans-Mexican Volcanic Belt(TMVB) and the Sierra Madre del Sur(SMS).Mean richness by latitudinal belts of one degree showed that the belts with highest values are related to the TMVB and SMS.A total of 13grid-cells were recognized as important from theperspective of endemism; most of them are located also in the SMO, TMVB and SMS.The richest gridcells coincided with one of the main centres of endemism for ferns obtained in this study, located in the convergence of the southern part of the SMO, the eastern portion of the TMVB and the northern part of the SMS, reflecting the high humidity existing on the mountain slopes facing the Gulf of Mexico.Some important grid-cells recognized from richness and endemism analyses coincide with Mexican Natural Protected Areas.The beta diversity analysis showed a low degree of similarity among grid-cells, implying a high species replacement, as the result of environmental heterogeneity occurring in the Mexican mountain systems.On the other hand, the spatial analysis suggested a pattern of phytogeographical regionalization comprising twomain areas: the Mexican Transition Zone and the Mexican Central Plateau.Ferns play an important role in the Mexican biodiversity and contributing to the beta diversity of Mexico.SANGINéS-FRANCO Celia LUNA-VEGA Isolda CONTRERAS-MEDINA Raúl ESPINOSA David TEJERO-DíEZ José Daniel RIVAS Gerardo 2015Journal of Mountain Science2015,12,4:1

4Long-lasting,reinforced electrical networking in a high-loading Li_(2)S cathode for high-performance lithium–sulfur batteries显示文摘Realizing a lithium sulfide(Li_(2)S)cathode with both high energy density and a long lifespan requires an innovative cathode design that maximizes electrochemical performance and resists electrode deterioration.Herein,a high-loading Li_(2)S-based cathode with micrometric Li_(2)S particles composed of two-dimensional graphene(Gr)and one-dimensional carbon nanotubes(CNTs)in a compact geometry is developed,and the role of CNTs in stable cycling of high-capacity Li–S batteries is emphasized.In a dimensionally combined carbon matrix,CNTs embedded within the Gr sheets create robust and sustainable electron diffusion pathways while suppressing the passivation of the active carbon surface.As a unique point,during the first charging process,the proposed cathode is fully activated through the direct conversion of Li_(2)S into S_(8) without inducing lithium polysulfide formation.The direct conversion of Li_(2)S into S_(8) in the composite cathode is ubiquitously investigated using the combined study of in situ Raman spectroscopy,in situ optical microscopy,and cryogenic transmission electron microscopy.The composite cathode demonstrates unprecedented electrochemical properties even with a high Li_(2)S loading of 10 mg cm^(–2);in particular,the practical and safe Li–S full cell coupled with a graphite anode shows ultra-long-term cycling stability over 800 cycles.Hun Kim Kyeong-Jun Min Sangin Bang Jang-Yeon Hwang Jung Ho Kim Chong SYoon Yang-Kook Sun 2023Carbon Energy2023,5,8:1

10企业如何在数字颠覆中赢得生机显示文摘过去30年,由于数字创新,商业界发生了戏剧性变化,只不过程度有限。虽然许多商业实践、产品和服务发生了演变,几个行业领域(如媒体)也发生了根本性变化,但核心业务被颠覆的企业却寥寥无几.不过这种局面即将发生改变,公司战略也将因此会受到影响。所有颠覆(数字或其他形式)都在整个行业内上演,迫使盈利渠道发生重大转变:由一种主流商业模式转向另一种。新模式通常以极低的成本为客户提供同样或更高的价值。Leslie H.Moeller Nick Hodson Martina Sangin 沈建苗 2018IT经理世界2018,0,13:1

12Ultralong persistent luminescence from carbon dots显示文摘Hour-level persistent luminescence is realized with carbon dots embedded in cyanuric acid,the composition of which is easily obtained by the microwave-assisted heating of carbon dots and urea.By forming donor-acceptor blends,the proposed composition yields intermediate states with long lifetimes,providing a rare-earth-metal-free route to ultralong persistent luminescence.Seunghyup Yoo Youngjin Song Sangin Hahn 2022Light(Science & Applications)2022,11,6:1

18猪的品种和饲粮中脂肪水平对氮和能量平衡的影响显示文摘文章探讨了猪品种和饲粮中脂肪水平对仔猪总表观消化率(RAD)和氮平衡的影响。将4只PM猪和4只约克夏和长白猪的杂交公猪(Y×L)(初始活重为39.2kg)分成两组,试验采用2×2因子设计,饲喂基础饲粮(每天每公斤代谢体重0.1kg)和试验饲粮。饲粮中30或150g粗脂肪被含有鳄梨浆的玉米豆粕型饲粮部分代替。在PM猪和约克夏和长白猪的杂交猪中粗脂肪的总表观消化率分别为73.8%和71.5%,氮的总表观消化率分别为83.4%和82.8%。粗蛋白水平对氮的总表观消化率和能量无显著影响(P>0.10)。约克夏猪和长白猪的杂交猪较PM猪氮和能量平衡显著(P<0.05)。结果表明,氮的贮留可能与机体构成有关而与基因型无关。鳄梨用于饲喂包括PM在内的猪,粗脂肪具有较高消化率,同时,可能是由于氨基酸组成的不平衡导致了氮滞留。猪饲粮中的鳄梨浆水平应包括这些情况。Grageola F Sangines L Díaz C Gómez A Cervantes M Lemus C Ly J 2010饲料博览2010,,8:0
19Aluminum nitride waveguide beam splitters for integrated quantum photonic circuits显示文摘We demonstrate integrated photonic circuits for quantum devices using sputtered polycrystalline aluminum nitride(Al N)on insulator.On-chip Al N waveguide directional couplers,which are one of the most important components in quantum photonics,are fabricated and show the output power splitting ratios from 50:50 to 99:1.Polarization beam splitters with an extinction ratio of more than 10 d B are also realized from the Al N directional couplers.Using the fabricated Al N waveguide beam splitters,we observe Hong–Ou–Mandel interference with a visibility of 91.7%±5.66%.HYEONG-SOON JANG DONGHWA LEE HYUNGJUN HEO YONG-SU KIM HYANG-TAG LIM SEUNG-WOO JEON SUNG MOON SANGIN KIM SANG-WOOK HAN HOJOONG JUNG 2023Photonics Research2023,11,7:0
