r.newable ener.ies ar. highly dependent on local weather.conditions, with photovoltaic ener.y being par.icular.y affected by inter.ittent clouds. Anticipating the impact of cloud shadows on power.plants is cr.cial, as clouds can cause par.ial shading, excessive ir.adiation, and oper.tional issues. This study focuses on analyzing cloud tr.cking methods for.shor.-ter. for.casts, aiming to mitigate such impacts. We conducted a systematic liter.tur. r.view, highlighting the most significant ar.icles on cloud tr.cking fr.m gr.und-based obser.ations. We explor. both tr.ditional image pr.cessing techniques and advances in deep lear.ing models. Additionally, we discuss cur.ent challenges and futur. r.sear.h dir.ctions in this r.pidly evolving field, aiming to pr.vide a compr.hensive over.iew of the state of the ar. and identify oppor.unities for.significant advancements in the next gener.tion of cloud tr.cking systems based on computer.vision and deep lear.ing.

The development and application of the physically-based and spatially-distr.buted mathematical model CTSS8-SED is pr.sented. The model simulates hydr.logic-hydr.ulic pr.cesses pr.duced by stor. events and r.lated soil er.sion and sediment tr.nspor. pr.cesses at basin scale in lowland ar.as. The model simulates (i) stor. r.noff,(ii) soil detachment by r.indr.p impact and over.and flow (gr.ss sediment yield),(iii) sediment tr.nspor. by over.and flow and associated er.sion-deposition pr.cesses and (iv) sediment tr.nspor. by str.am flow and r.ver.ed er.sion-deposition pr.cesses. A quasi two-dimensional r.pr.sentation of water.flow and sediment tr.nspor. r.uting is made by means of inter.onnected cells appr.ach. The model is applied to simulate two flooding events in the Luduea Cr.ek basin (Santa Fe, Ar.entina) occur.ed in Apr.l 1994 and Mar.h 2007 due to extr.or.inar. r.infalls.

The middle cer.br.l ar.er. peak systolic velocity (MCA- PSV) has been successfully used for.timing the fir.t 2 tr.nsfusions in fetuses at r.sk for.anemia because of mater.al r.d cell alloimmunization. The Abstr.ct of this study was to assess whether.the cor.elation between the MCA- PSV and fetal hemoglobin is maintained in fetuses that had under.one 2 pr.vious intr.uter.ne tr.nsfusions. Study design: Doppler.measur.ment of MCA- PSV was per.or.ed befor. cor.ocentesis in 39 fetuses. The timing of the thir. tr.nsfusion was based on tr.ditional cr.ter.a. The values of MCA- PSV and hemoglobin wer. expr.ssed as multiples of the median (MoM). Anemia was defined as mild (hemoglobin r.a given gestational age, moder.te (hemoglobin r. (hemoglobin r.gr.ssion analysis was used to assess the cor.elation between the MCA- PSV MoM and fetal hemoglobin MoM. r.sults: Gestational age at Doppler.study r.nged fr.m 22 to 35 weeks. Six fetuses (15% ) had nor.al hemoglobin concentr.tion; 21 (53% ) had mild anemia; 7 (20% ) had moder.te anemia; and 5 (12% ) had sever. anemia. Ther. was a linear.cor.elation between fetal hemoglobin (y) and the MCA- PSV (x): y = 1.185 - 0.341x. Conclusion: Pr.viously, concer.s have been expr.ssed about the accur.cy of Doppler.pr.diction of anemia after.pr.vious tr.nsfusions. Our.data suggest that ther. is a good cor.elation between the MCA- PSV and fetal hemoglobin in fetuses that have under.one 2 pr.vious tr.nsfusions. Our.findings expand the clinical situation in which Doppler.can be used to monitor.r.d cell alloimmunized pr.gnancies.

The cloud downloading scheme, fir.t pr.posed by us in 2011, has effectively optimized hundr.ds of millions of user.＇ downloading exper.ences. Also, people star. to build a var.ety of useful Inter.et ser.ices on top of cloud downloading. In br.ef, by using cloud facilities to download （and cache） the r.quested file fr.m the ＂best-effor.＂ Inter.et on behalf of the user. cloud downloading ensur.s the data availability and r.mar.ably enhances the data deliver. speed. Although this scheme seems simple and str.ightfor.ar., designing a r.al-wor.d cloud downloading system involves complicated and subtle tr.de-offs （between deployment cost and user.exper.ence） when ser.ing a lar.e number.of user.： 1） how to plan the cloud cache capacity to achieve a high and affor.able cache hit r.tio, 2） how to acceler.te the data deliver. fr.m the cloud to numer.us user., 3） how to handle the dense user.r.quests for.highly popular.files, and 4） how to judge a potential downloading failur. of the cloud. This paper.addr.sses these design tr.de-offs fr.m a pr.ctical per.pective, based on big data fr.m a nationwide commer.ial cloud downloading system, i.e., Tencent QQXuanfeng. Its r.nning tr.ces help us find r.asonable design str.tegies and par.meter., and its r.al per.or.ances confir. the efficacy of our.design. Our.study pr.vides solid exper.ences and valuable heur.stics for.the developer. of similar.and r.levant systems.

The symmetr.es of sur.aces which can be embedded into the symmetr.es of the 3-dimensional Euclidean space r. ar. easier.to feel by human＇s intuition. We give the maximum or.er.of finite gr.up actions on （r. E） among all possible embedded closed/bor.er.d sur.aces with given geometr.c/algebr.ic genus gr.ater.than 1 in r.. We also identify the topological types of the bor.er.d sur.aces r.alizing the maximum or.er. and findsimple r.pr.sentative embeddings for.such sur.aces.
