Ultrathin optical interference in a system composed of absorbing material and metal reflector has attracted extensive attention due to its potential application in realizing highly efficient optical absorption by using extremely thin semiconductor material. In this paper, we study the physics behind the high absorption of ultrathin film from the viewpoint of destructive interference and admittance matching, particularly addressing the phase evolution by light propagation and interface reflection. The physical manipulations of the ultrathin interference effect by controlling the substrate material and semiconductor material/thickness are examined. We introduce typical two-dimensional materials — i.e., MoS2and WSe2— as the absorbing layer with thickness below 10 nm, which exhibits ～ 90% absorption in a large range of incident angle(0°～70°). According to the ultrathin interference mechanism, we propose the ultrathin(cation and carefully examine the detailed optoelectronic responses by coupled multiphysics simulation. By comparing the same cells on SiO2substrate, both the short-circuit current density(up to 20 mA/cm~2) and the photoelectric conversion efficiency(up to 9.5%) are found to be increased by ～200%.

目的:探讨经阴道超声联合宫腔镜诊治子宫内膜异常的价值。方法:经阴道超声记录患者自然月经周期、排卵期内膜厚度、回声、三线征情况。根据内膜情况分为异常组(观察组)和正常组(对照组),进行宫腔镜检查和诊治术,观察术后内膜恢复情况,分析治疗后一年内的妊娠率和妊娠结局。结果:观察组40例患者宫腔镜检查结果异常35例,与B超结果符合率87.5%;对照组22例宫腔镜检查结果正常21例,符合率95.45%。观察组中确诊内膜异常者35例,妊娠率48.57%(17/35),对照组确诊为内膜正常者21例,妊娠率71.43%(15/21),P0.05,两组比较差异有显著意义,行宫腔镜检查和诊治术后复查内膜恢复正常者观察组占4096(14/35)。其妊娠率为64.29%(9/14),继续异常组妊娠率38.10%(8/21),两者间无统计学差异。观察组和对照组足月分娩率相比,P>0.05,两组间无差异。内膜厚度<6mm的6例患者中2例妊娠,均有早期先兆流产症状,经保胎治疗,1例足月分娩,1例孕早期流产。结论:超声监测联合宫腔镜有助于诊断子宫内膜病变。子宫内膜厚度≥8mm<16mm、三线征明显且回声均匀对妊娠有利;内膜厚度<6mm仍有妊娠机会,但要及时保胎治疗。

Celebrating Plant Cells:A Special Issue on Plant Cell Biology

＜正＞ The Anticosti Basin, located in the northern part of gulf of St. Lawrence and centered at Anticosti Island, eastern canada, is an Early Paleozoic marine basin formed in the eastern margin of the Laurentia continent. It constitutes part of the St. Lawrence Platform. The Maritimes Basin, covering much of the southern part of gulf of St. Lawrence and surrounding onshore areas, is a Late Paleozoic continental successor basin. It is the uppermost tectonic constituent of the Appalachian Orogen. The Anticosti Basin consists of cambrian to Lower Ordovician passive margin sediments and Middle Ordovician to Lower Silurian foreland basin sediments, intervened by the Taconian Orogeny in Middle Ordovician. The Maritimes Basin is filled with Upper Devonian to

A special issue on plant cell biology is long overdue for JIPB! In the last two decades or so, the plant biology community has been thrilled by explosive discoveries regarding the molecular and genetic basis of plant growth, development, and responses to the environment, largely owing to recent maturation of model systems like Arabidopsis thaliana and the rice Oryza sativa, as well as the rapid development of high throughput technologies associated with qenomics and proteomics.
