Quantum uncertainty relations constrain the precision of measurements across multiple non-commuting quantum mechanical ***,we introduce the concept of optimal observable sets and define the tightest uncertainty constants to accurately describe these measurement *** any quantum state,we establish optimal sets of three observables for both product and summation forms of uncertainty relations,and analytically derive the corresponding tightest uncertainty *** demonstrate that the optimality of these sets remains consistent regardless of the uncertainty relation ***,the existence of the tightest constants excludes the validity of standard real quantum mechanics,underscoring the essential role of complex numbers in this ***,our findings resolve the conjecture posed in[***.118,180402(2017)],offering novel insights and potential applications in understanding preparation uncertainties.

The steady intensity of a forward phase conjugate wave (FPCW) is successfully observed along the c-axis in the highly magnesium-doped lithium niobate crystal. We put forward a detailed physical picture for our experiment phenomena. The FPCW is generated from the phase-mismatch in a three-wave coupling process, and tends to be stable accompanied with the building of photorefractive gratings and four-wave coupling processes. Our experimental result is also discussed and analysed by means of the wave coupling theory, and the theoretical expression is provided for the experiment.

目的探讨宫颈鳞癌中程序性死亡配体1(PD-L1)表达情况及22C3、SP263、E1L3N 3种抗体免疫组化染色的一致性。方法收集解放军总医院两个医学中心89例复发或转移性宫颈鳞癌样本,用PD-L13种克隆号抗体22C3、SP263、E1L3N进行染色,并采用联合阳性评分(CPS)、肿瘤细胞比例评分(TPS)两种评分标准,在不同阈值下对抗体的一致性进行统计学分析。结果宫颈鳞癌在CPS阳性阈值为1时,PD-L1阳性率从高到低依次为22C3(98.31%)、E1L3N(97.75%)、SP263(93.90%);CPS为10时,阳性率依次为E1L3N(76.40%)、22C3(72.88%)、SP263(69.51%);TPS阈值为1%时,阳性率依次为E1L3N(95.51%)、22C3(93.22%)、SP263(92.68%);TPS为10%时,阳性率依次E1L3N(65.17%)、22C3(64.41%)、SP263(60.98%)。当CPS为1或10时、TPS为1%或10%时,E1L3N与22C3、SP263与22C3、SP263与E1L3N均表现较好的一致性(Kappa=0.66~0.98)。无论使用CPS或TPS,组内相关系数检验显示3个克隆号抗体判读数据有高度一致性(ICC分别为0.987、0.984)。结论E1L3N、SP263与22C3之间具有较高的可互换性,为临床检测PD-L1在宫颈癌组织中的表达情况,提供了更多选择。

为探索花蕾期提早施用稳果肥对冰糖橙树体生长发育和果实品质的影响,以常规管理方式中花后10 d施肥为对照(CK),露白后开花前的花蕾期施肥替代稳果肥为处理,分析比较了春梢长度、春梢粗度、叶片形态、叶片叶绿素SPAD值、叶片色泽、果实外观品质和内在品质等指标。结果表明:花蕾期施肥后,春梢长度和粗度显著高于CK,叶长、叶宽相较CK显著提升14.5%~27.2%和18.6%~331.7%,叶绿素SPAD值显著增加7.1%~15.2%,叶片转绿老熟更快。花蕾期施肥促进了柑橘细胞的分裂和果实增大,5月中旬至6月上旬幼果横径为13.91~21.67 mm,单果重为1.83~5.95 g,显著高于CK;膨大期果实横径和单果重显著增加了7.2%和26.7%,可滴定酸含量比CK高0.39个百分点;进入果实转色期,果实横径和单果重显著比CK高5.8%和17.7%,可滴定酸含量比CK高0.39个百分点;果实达到成熟期时,果实横径和单果重仍比CK高3.4%和13.1%,且成熟果实着色更饱满,果面光亮,果皮橙黄,但果实内在品质并无显著差异。因此,花蕾期提早施用稳果肥更有利于加速春梢发育和增进果实膨大。

LetΩbe a bounded smooth domain in RN(N≥3).Assuming that 00 are constants,we consider the existence results for positive solutions of a class of fractional elliptic system below,{(a+b[u]^(2)_(s))(-Δ)^(s)u=vp+h_(1)(x,u,v,▽u,▽v),x∈Ω,(-Δ)^(s)v=u^(q)+h_(2)(x,u,▽,▽u,▽v),x∈Q,u,v>0,x∈Ω,u=v=0,x∈RN\Ω.Under some assumptions of hi(x,u,v,▽u,▽v)(i=1,2),we get a priori bounds of the positive solutions to the problem(1.1)by the blow-up methods and rescaling *** on these estimates and degree theory,we establish the existence of positive solutions to problem(1.1).
