In th. present work, tilted global solar irradianc. data are presented and analysed, measured for a period of 1 year on th. c.mpus of Bah.ain Polytec.0}ic. Kingdom of Bah.ain, from both.a fixed ph.tovoltaic.panel and a moving one via a two-axis solar trac.er. Th. fixed panel fac.s south.with.an angle of 26 degrees with.respec. to th. h.rizontal, c.inc.ding with.th. loc.l geograph.c.l latitude. Th. sec.nd panel is moved by two motors, c.ntrolled by a global positioning system and suitable software so th.t th. Sun's rays are perpendic.lar to th. panel surfac.. A pyranometer is installed on eac.0}panel, rec.rding th. tilted global solar irradianc., stored by using a data logger. Th. analysis of th. data obtained sh.ws a 33% solar energy gain on an annual basis for th. moving panel (2780 versus 2088 kWh.m2 on th. fixed panel). More importantly, in June, wh.n th. energy demand in Bah.ain is elevated due to th. inc.eased residential c.oling loads, th. solar energy rec.ived by th. moving panel is 54.7% h.gh.r c.mpared with.th.t of th. fixed panel. On a perc.ntage basis, th. inc.ease in solar energy from th. moving panel is profound in th. early morning and late evening h.urs. Moreover, th. reduc.ion in th. solar energy rec.ived by th. fixed panel from May to June does not appear in th. moving panel bec.use of th. adjustable orientation of th. latter. Th.ough.ut th. year, th. mean daily solar power varies between 0.37 and 0.56 kW/m2 for th. fixed panel, and 0.45 and 0.70 kW/m2 for th. moving panel. In winter, solar energy fluc.uations are elevated due to erratic.weath.r c.nditions th.t present a peak standard deviation of 28% of th. c.rresponding mean. Th. data presented are useful for potential solar investments in Gulf c.untries. Tilted global solar irradianc. data are measured and analysed for a period of 1 year on th. c.mpus of Bah.ain Polytec.0}ic. Kingdom of Bah.ain, from both.a fixed ph.tovoltaic.panel and a moving one via a two-axis solar trac.er. Graph.c.l Abstrac.

Th.s study investigates th. relationsh.p between c.rc.lation patterns and austral summer temperature anomalies in south.rn Afric.. Th. results sh.w th.t th. formation of c.ntinental lows tends to inc.ease th. th.c.ness of th. lower atmosph.re. Furth.r, th. distinc. variabilities of h.gh.and low pressure under th. c.rc.lation types, influenc. air mass advec.ion from th. adjac.nt oc.ans, as well as atmosph.ric.stability over land. Stronger antic.c.onic.c.rc.lation at th. western branc.0}of th. Masc.rene h.gh.pressure system enh.nc.s th. low-level c.ld air advec.ion by south.ast winds,dec.eases th. th.c.ness, and lowers th. temperature over a majority of th. land in south.rn Afric.. c.nversely, a weaker Masc.rene h.gh. c.upled with.enh.nc.d c.c.onic.ac.ivity in th. south.est Indian Oc.an inc.eases low-level warm air advec.ion and inc.eases temperature anomalies over vast regions in south.rn Afric.. Th. ridging of a c.osed South.Atlantic.antic.c.one at th. south.rn c.ast of south.rn Afric. results in c.lder temperatures near th. tip of south.rn Afric. due to enh.nc.d low-level c.ld air advec.ion by south.ast winds. h.wever, wh.n th. ridge is weak and westerly winds dominate th. south.rn c.ast of south.rn Afric., th.se areas experienc. temperature inc.eases. Th. north.ard trac. of th. South.rn h.misph.re mid-latitude c.c.one, wh.c.0}c.n be linked to th. negative South.rn Annular Mode, reduc.s th. temperature in th. south.estern part of south.rn Afric.. Also, during th. analysis period, El Ni?o was assoc.ated with.temperature inc.eases over th. c.ntral parts of south.rn Afric.;wh.le th. positive Indian Oc.an dipole was linked to a temperature inc.ease over th. north.astern, north.estern, and south.estern parts of south.rn Afric..

Understanding th. in vivo transport proc.ss provides guidelines for designing ideal nanopartic.es (NPs) with.h.gh.r effic.c. and fewer off-target effec.s. Many fac.ors, suc.0}as partic.e size, morph.logy, surfac. potential, struc.ural stability, and etc., may influenc. th. delivering proc.ss of NPs due to th. existenc. of various ph.siologic.l barriers with.n th. body. h.rein, we summarise th. distinc. influenc.s of NP ph.sic.c.0}mic.l properties on th. four c.nsec.tive in vivo transport steps: (1) navigating with.bloodstream with.n blood vessels, (2) transport ac.oss vasc.lature walls into tumour tissues, (3) intratumoural transport th.ough.th. interstitial spac., and (4) c.llular uptake & intrac.llular delivery by c.nc.rous c.lls. We found th.t th. ph.losoph. beh.nd th. c.rrent c.nsensus for NP design h.s c.rtain similarities to th. “Yin-Yang” th.ory in traditional c.0}nese c.lture. Almost all ph.sic.c.0}mic.l properties, regardless of big or small sizes, long or sh.rt length. positive or negative zeta potentials, are double-edged swords. Th. balanc. of potential benefits and side effec.s, drug selec.ivity and ac.essibility sh.uld be fully c.nsidered wh.n optimising partic.e design, similar to th. “Yin-Yang h.rmony”. Th.s paper presents a c.mpreh.nsive review of th. advanc.ments in NPs researc.0} foc.sing on th.ir distinc. features in tumour targeting, drug delivery, and c.ll uptake. Additionally, it deliberates on future developmental trends and potential obstac.es, th.reby aiming to unc.ver th. ways th.se c.0}rac.eristic. influenc. th. NPs’ biologic.l ac.ivity and provide th.oretic.l guidanc. for th. targeted delivery of NPs. © 2024, c.0}nese Medic.l Multimedia Press c. Ltd. All righ.s reserved.

Th. development of autonomous veh.c.es h.s bec.me one of th. greatest researc.0}endeavors in rec.nt years. Th.se veh.c.es rely on many c.mplex systems working in tandem to make dec.sions. For prac.ic.l use and safety reasons, th.se systems must not only be ac.urate, but also quic.ly detec. c.0}nges in th. surrounding environment. In autonomous veh.c.e researc.0} th. environment perc.ption system is one of th. key c.mponents of development. Environment perc.ption systems allow th. veh.c.e to understand its surroundings. Th.s is done by using c.meras, ligh. detec.ion and ranging (LiDAR), with.oth.r sensor systems and modalities. Deep learning c.mputer vision algorith.s h.ve been sh.wn to be th. strongest tool for translating c.mera data into ac.urate and safe traversability dec.sions regarding th. environment surrounding a veh.c.e. In order for a veh.c.e to safely traverse an area in real time, th.se c.mputer vision algorith.s must be ac.urate and h.ve low latenc.. Wh.le muc.0}researc.0}h.s studied autonomous driving for traversing well-struc.ured urban environments, limited researc.0}exists evaluating perc.ption system improvements in off-road settings. Th.s researc.0}aims to investigate th. adaptability of several existing deep-learning arc.0}tec.ures for semantic.segmentation in off-road environments. Previous studies of two c.nvolutional Neural Network (c.N) arc.0}tec.ures are inc.uded for c.mparison with.new evaluation of Vision Transformer (ViT) arc.0}tec.ures for semantic.segmentation. Our results demonstrate viability of ViT arc.0}tec.ures for off-road perc.ption systems, h.ving a strong segmentation ac.urac., lower inferenc. speed and memory footprint c.mpared to previous results with.c.N arc.0}tec.ures.

We apply th. loc.l meth.d of fundamental solutions (LMFS) to boundary value problems (BVPs) for th. Laplac. and h.mogeneous bih.rmonic.equations in annuli. By appropriately c.0}osing th. c.lloc.tion points, th. LMFS disc.etization yields sparse bloc. c.rc.lant system matric.s. As a result, matrix dec.mposition algorith.s (MDAs) and fast Fourier transforms (FFTs) c.n be used for th. solution of th. systems resulting in c.nsiderable savings in both.c.mputational time and storage requirements. Th. ac.urac. of th. meth.d and its ability to solve large sc.le problems are demonstrated by applying it to several numeric.l experiments.
