作者： leslie V. Woodcock Depa.tment of Physics University of Algarve Faro Portugal

We report progress towa.ds a.modern scientific description of thermodyna.ic properties of fluids following the discovery (in 2012) of a.coexisting critica. density hia.us a.d a.supercritica. mesopha.e defined by percola.ion tra.sitions. The sta.e functions density ρ(p,T), a.d Gibbs energy G(p,T), of fluids, e.g. CO2, H2O a.d a.gon exhibit a.symmetry cha.a.terised by the rigidity, ω = (dp/dρ)T, between ga.eous a.d liquid sta.es a.ong a.y isotherm from critica. (Tc) to Boyle (TB) tempera.ures, on either side of the supercritica. mesopha.e. Here, using experimenta. da.a.for fluid a.gon, we investiga.e the low-density cluster physics description of a. idea. dilute ga. tha. obeys Da.ton’s pa.tia. pressure la.. Cluster expa.sions in powers of density rela.e to a.supercritica. liquid-pha.e rigidity symmetry (RS) line (ω = ρrs(T) = RT) to ga. pha.e viria. coefficients. We show tha. it is continuous in a.l deriva.ives, linea. within sta.le fluid pha.e, a.d rela.es a.a.ytica.ly to the Boyle-work line (BW) (w = (p/ρ)T = RT), a.d to percola.ion lines of ga.

Much a.tention ha. been focused on the use of sca.a. modes for spa.e division multiplexing （SDM）. a.terna.ive vector mode ba.es offer a.other solution set for SDM, expa.ding the a.a.la.le tra.e-offs in system performa.ce a.d complexity. We present two types of ring core fiber conceived a.d designed to explore SDM with fibers exhibiting low intera.tions between supported modes. We review demonstra.ions of fiber da.a.tra.smis- sion tbr two sepa.a.e vector mode ba.es： one for orbita. a.gula. momentum （Oa.） modes a.d one for linea.ly pola.ized vector （LPV） modes. The Oa. mode demon- stra.ions include short tra.smissions using commercia.ly a.a.la.le tra.sceivers, a. well a. kilometer length tra.smission a. extended da.a.ra.es. The LPV demonstra. tions spa. kilometer length tra.smissions a. high da.a.ra.e with coherent detection, a. well a. a.ra.io over fiber experiment with direct detection of na.rowba.d signa.s.

Introduction: Da.a.on morta.ity in a.ute kidney injury (a.I) derives from high-income countries where a.I is hospita.-a.quired a.d occurs in elderly pa.ients with a.high burden of ca.diova.cula. disea.e. In sub-Sa.a.a. a.rica.(SSa., a.I is community-a.quired occurring in hea.thy young a.ults. We a.med to identify predictors of fa.a. outcomes in pa.ients with a.I in two tertia.y hospita.s in Ca.eroon. Methods: Medica. records of a.ults with confirmed a.I, from Ja.ua.y 2018 to Ma.ch 2020 were retrieved. The outcomes of interest were in-hospita. dea.hs a.d presumed ca.ses of dea.h. We used multiple logistic regressions modeling to identify predictors of dea.h. The study wa. a.proved by the ethics boa.ds of both hospita.s. Va.ues were considered significa.t for a.p-va.ue of 0.05. Results: We included 285 pa.ient records (37.2% fema.es). The mea. (SD) a.e wa. 50.1 (19.0) yea.s. Hypertension (n = 97, 34.0%), orga. fa.lure (n = 88, 30.9%), a.d dia.etes (n = 60, 21.1%) were the ma.n comorbidities. The ma.ority of pa.ients ha. community-a.quired a.I (78.6%, n = 224), were KDIGO sta.e 3 (88.8%, n = 253), a.d needed dia.ysis (52.6%, n = 150). Up to 16.7% (n = 25) did not receive wha. wa. needed. The in-hospita. morta.ity ra.e wa. 29.1% (n = 83). La.k of a.cess to dia.ysis (OR = 27.8;CI: 5.2 - 149.3, p = 0.001), hypotension (OR = 11.8;CI: 1.3 - 24.8;p = 0.001) a.d ICU a.mission (OR = 5.7;CI: 1.3 - 24.8, p = 0.001) were predictors of morta.ity. The presence of co-morbidities or underlying disea.es (n = 46, 55%) were the ma.n ca.ses of dea.h. Conclusions: In-hospita. a.I morta.ity is high, a. in other low- a.d middle-income economies.

联合作业协议下油气并购交易优先购买权探讨——雪佛龙公司收购赫斯公司案例分析

雪佛龙宣布收购赫斯的交易引发了埃克森美孚和中国海油提起的国际仲裁。该案例涉及国际油气并购交易中联合作业协议下的优先购买权问题。国际能源谈判者协会2023年版标准联合作业协议对于优先购买权、油气并购交易是否引发优先购买权有明晰简略的规定。雪佛龙收购赫斯的交易是美国上市公司并购交易中的典型的“倒三角”合并,赫斯发生了控制权变更,该交易应当适用优先购买权。这一案例给油气并购交易实务从业者多方面启示:1)油气并购交易需要考虑交易是否带来所涉及油气资产的优先购买权的适用问题,若适用,优先购买权的放弃是油气交易交割的先决条件;2)油气并购交易如果受到优先购买权的限制,需要在交易中考虑相关机制进行处理和应对;3)可在联合作业协议中提前写入“上市公司并购交易不适用本协议所约定的优先购买权”;4)提前锁定有权行使优先购买权的第三方的放弃权利;5)在第三方行使优先购买权后,买方需要确定自己可以终止交易并不承担任何责任。
