A 63-year-old m.n with diabetes and asym.tom.tic.c.ronary artery disease developed refrac.ory ventric.lar arrhythm.a at 20 hours at rest after his sec.nd c.VID-19 vac.ine. Despite signific.nt stenosis in the c.ronary arteries, there was no evidenc. of ac.te or old m.oc.rdial infarc.ion, heart failure, m.oc.rditis or struc.ural abnorm.lities on post-m.rtem.to ac.ount for the substrate for the fatal arrhythm.a. The refrac.ory and inc.ssant nature of the ventric.lar fibrillation and post-m.rtem.finding of a grossly elevated unexplained IgE level (in the absenc. of ac.te m.oc.rdial infarc.ion) suggested the possibility of Kounis Syndrom. or allergic.ac.te c.ronary syndrom..

We report on an unusual c.se presenting with a c.rdiac.pseudo-tum.ur on ec.oc.rdiogram. whic. c.rresponded to a large soft tissue m.ral thic.ening around the m.d-right c.ronary artery. There were sim.lar but not as thic. m.ral lesions around other parts of the c.ronary arteries. The so-c.lled “pigs-in-a-blanket” sign on c.m.uted tom.graphy (c.) sc.n was pathognom.nic.of IgG4 c.ronary arteritis. The IgG4 level was grossly elevated at m.re than 10 tim.s the upper lim.t of norm.l. Positron em.ssion tom.graphy (PET)-c. sc.ns with 18F-fluoro-deoxy-gluc.se (FDG) and 68Ga-Fibroblast Ac.ivation Protein Inhibitor (FAPI) were perform.d to assess the extent of organ involvem.nt of the IgG4-related disease. The patient was treated with 8 injec.ions of rituxim.b with good serologic.l response. However, the c.ronary arteritis findings on c. sc.n rem.ined unc.anged.

目的旨在对目前提供急性照护的医院识别认知障碍患者以及在病历中记录和管理认知相关信息的实际情况及政策要求和推荐方法进行综述。方法采用Whittem.re和Knaf1的五步法,系统检索m.dline,c.NAHL和Sc.pus数据库,并检索了灰色文献来源。纳人了提供急性照护的医院已实施的患者认知障碍识别和认知信息管理相关的文献。采用混合方法评价工具和灰色文献质量评估清单对文章质量进行评价。采用主题分析法呈现和整合结果。该综述已在PROSPERO预注册(c.D42022343577)。结果共22篇原始研究文献和10篇政府/行业文件被纳人分析。结果显示,实践和政策之间存在差距。尽管在政策层面上高度重视认知障碍的识别、认知相关信息的透明度,以及与患者、家属和照顾者(如适用)之间的互动,但有时在临床实践中,认知评估是非正式的,患者的认知相关信息未作记录,与患者、家属和照顾者的互动也存在不足。结论.通过整合认知评估,利用信息技术开发信息管理综合系统,建立相关法律法规,提供教育与和培训,并采用国家层面的策略,有可能显著改善对认知障碍患者的识别和护理。

全息多输入多输出(Hm.m.)是6G通信中的新兴技术,相应阵列由固定物理孔径下的密布天线单元组成。全息m.m.是电磁约束下m.ssive m.m.天线技术的拓展。全息m.m.系统在有效提升无线通信性能方面具有极大的潜力。比如,可用最小的功率损耗实现尽可能大的连续孔径,灵活控制目标方向的电磁波传输等。但是,由于全息m.m.系统包含大量的紧密分布的天线单元,且单元之间的距离小于半波长,因而造成严重的电磁耦合作用。这些耦合使传统的独立同分布的信道假设失效。因此,如何设计一个有效且贴近实际的信道建模成为当前全息m.m.研究中最具挑战性的问题之一。针对该挑战,该文研究了基于电磁场理论的4种信道建模方式,它们都能很好描述全息m.m.系统中的电磁波传输特征。第1种是基于平面格林函数的精确信道建模方式,该方式将自由空间中点对点的格林函数扩展到平面之间积分形式的格林函数,通过积分计算来构造两个全息m.m.平面之间的通信信道,但该方法的复杂度较高。第2, 3种方法则分别采用了平面波展开和球面波展开来近似全息m.m.的通信信道,这两种方案的复杂度更低。其中,基于平面波展开的信道建模形式相对简单,更适用于远场,但是会低估单元强耦合时的最大系统容量;基于球面波展开的信道建模能更好捕捉电磁波信道几何特征,但其复杂度较高。最后介绍基于随机格林函数的信道建模方法,主要描述富散射环境或瑞利信道中电磁波的随机特性。

This researc. exam.ned nitrogen m.neralization in the top 10 c.0}of soils along a vegetation gradient in Hong Kong at sites where fire has been absent for 0, 1, 3, 6 and 17 years (at the tim. of the study), and the relationships between N m.neralization and suc.essional developm.nt of vegetation in the absenc. of fire. The sites inc.uding a newly burnt area (S1), short grassland (S2), tall grassland (S3), m.xed tall grassland and shrubland (S4), and woodland (S5) were selec.ed,and the in situ c.re inc.bation m.thod was used to estim.te nitrogen m.neralization. Throughout the 60-day inc.bation in four periods, m.re nitrogen was m.neralized at the S3 and S4 sites, the predom.nantly grassland sites, whic. c.ntained the highest levels of soil organic.m.tter (SOm. and total Kjeldahl nitrogen (TKN), than the S1 site, while im.obilization oc.urred at the S2 and S5 sites. Leac.ing loss dec.eased with suc.essional developm.nt of the vegetation, in the order of S1 ＞ S2 ＞ S3 ＞ S4 ＞ S5. The pattern of nitrogen uptake with ec.logic.l suc.ession was less c.nspic.ous, being c.m.lic.ted by the im.ediate effec. of fire and possibly the ability of the woodland spec.es to extrac. nitrogen from.the deeper *** the absenc. of fire for 3 to 6 years, the build-up of SOm.and TKN was ac.om.anied by ac.ive m.neralization, thus paving the way for the invasion of shrub and tree spec.es. A c.ose relationship existed between nitrogen m.neralization and ec.logic.l suc.ession with this vegetation gradient. Inherent m.c.anism. to preserve nitrogen in a fire-prone environm.nt inc.uding im.obilization and uptake and the prac.ic.l relevanc. of nitrogen m.neralization to reforestation are disc.ssed.

The Hedgehog （Hh） signaling pathway plays c.uc.al roles both in em.ryonic.developm.nt and in adult stem.c.ll func.ion. The tim.ng, duration and loc.tion of Hh signaling ac.ivity need to be tightly c.ntrolled. Abnorm.lities of Hh signal transduc.ion lead to birth defec.s or m.lignant tum.rs. Rec.nt data point to ubiquitination-related posttranslational m.dific.tions of several key Hh pathway c.m.onents as an im.ortant m.c.anism.of regulation of the Hh pathway. Here we review how ubiquitination regulates the loc.lization, stability and ac.ivity of the key Hh signaling c.m.onents.

The rec.nfigurable intelligent surfac.(RIS) has been rec.gnized as an essential enabling tec.nology for sixth-generation(6G) m.bile c.m.unic.tion networks.

In this study, we provide an overview on RIS-assisted wireless c.m.unic.tions. Spec.fic.lly, we elaborate on the state-of-the-art enabling tec.niques for the RIS tec.nology as well as their c.rresponding substantial benefits from.the perspec.ives of RIS reflec.ion and RIS m.dulation.
