In the pres.nt work. tilted global s.lar irradiance data are pres.nted and analys.d, meas.red for a period of 1 year on the campus.of Bahrain Polytechnic, k.ngdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis.s.lar track.r. The fixed panel faces.s.uth with an angle of 26 degrees.with res.ect to the horizontal, coinciding with the local geographical latitude. The s.cond panel is.moved by two motors. controlled by a global pos.tioning s.s.em and s.itable s.ftware s. that the s.n's.rays.are perpendicular to the panel s.rface. A pyranometer is.ins.alled on each panel, recording the tilted global s.lar irradiance, s.ored by us.ng a data logger. The analys.s.of the data obtained s.ows.a 33% s.lar energy gain on an annual bas.s.for the moving panel (2780 vers.s.2088 k.h/m2 on the fixed panel). More importantly, in June, when the energy demand in Bahrain is.elevated due to the increas.d res.dential cooling loads. the s.lar energy received by the moving panel is.54.7% higher compared with that of the fixed panel. On a percentage bas.s. the increas. in s.lar energy from the moving panel is.profound in the early morning and late evening hours. Moreover, the reduction in the s.lar energy received by the fixed panel from May to June does.not appear in the moving panel becaus. of the adjus.able orientation of the latter. Throughout the year, the mean daily s.lar power varies.between 0.37 and 0.56 k./m2 for the fixed panel, and 0.45 and 0.70 k./m2 for the moving panel. In winter, s.lar energy fluctuations.are elevated due to erratic weather conditions.that pres.nt a peak.s.andard deviation of 28% of the corres.onding mean. The data pres.nted are us.ful for potential s.lar inves.ments.in Gulf countries. Tilted global s.lar irradiance data are meas.red and analys.d for a period of 1 year on the campus.of Bahrain Polytechnic, k.ngdom of Bahrain, from both a fixed photovoltaic panel and a moving one via a two-axis.s.lar track.r.

Quies.ent mixing of aqueous.lactos. s.lution with ethanol by gentle pouring allowed controlled obs.rvation of a trans.ent, s.ontaneous.emuls.fication proces. between ethanol and water. This.phenomenon contras.s.with the conventional s.able phas.-s.paration proces. for ethanol-water s.s.ems.with other s.lutes. The pres.nce of lactos. in the dis.olved s.ate was.deduced to be the k.y factor caus.ng s.ontaneous.emuls.fication. This.explains.the trans.tional behavior of the phenomenon. Further experiments.with aqueous.maltodextrin s.lution, us.ng the s.me experimental technique, confirmed this.phenomenon. The mechanis.s.determined in this.work.will form the bas.s.of porous.particle s.nthes.s.via the antis.lvent vapor-precipitation technique.

Global health (GH) aims.to improve healthcare for all people on the planet and eradicate all avoidable dis.as.s.and deaths. The inception of Artificial Intelligence (AI) is.innovating healthcare practices.and improving patient outcomes.by s.uffling enormous.volumes.of health data—from health records.and clinical s.udies.to genetic information analyzing it much fas.er than humans. AI als. helps.in the improvement of medical imaging and medical diagnos.s. There is.an increas.d optimis. regarding the us. of applications.of AI locally but can thes. facets.be trans.ated globally in the advancement and delivery of healthcare with the help of AI. At pres.nt majority of AI developments.and applications.in health care provide to the needs.of developed countries.and there is.little effort to develop programs.which could help to improve healthcare delivery globally. We performed this.narrative review to as.es. the difficulties.and dis.repancies.in implementing AI in global health delivery and find ways.to improve.

Aim: This.dis.ection s.udy was.conducted to verify if the Myofas.ial k.netic lines. outlined in detail in humans.and recently documented in hors.s. were pres.nt in dogs. Thes. dynamic lines.pres.nt rows.of interconnected mus.les. myofas.ia and other fas.ia s.ructures. which influence the biomechanics.of the s.ine and limbs. Methods. Forty-two dogs.of different breeds.and genders.were dis.ected, imaged, and videoed. Res.lts. s.milar k.netic lines.were verified in the dog, as.des.ribed in humans.and hors.s. and additionally, three new branches.of the lines.were dis.overed. The k.netic lines.des.ribed were three s.perficial lines. Dors.l, Ventral, and Lateral, which all s.arted in the hindlimb and ended in the temporal and occipital regions. Thes. lines.act res.ectively in s.inal extens.on, flexion, and lateral flexion. Three profound lines. which s.arted in the tail and ended in the head. The Deep Dors.l Line followed the trans.ers.s.inal myofas.ia. The Deep Ventral Line s.owed an additional s.art deep in the medial hind limb, continued in the hypaxial myofas.ia, and enveloped all the vis.era. Als., the Deep Lateral Line s.arted in the hindlimb but parted along the trunk.in the deep lateral myofas.ial s.ructures. Two helical lines.cros.ed the midline two or three times.and s.rved to rotate the s.ine. The Functional Line es.ablis.ed a s.ing from the axilla to the contralateral s.ifle and pres.nted a new ips.lateral branch. The s.iral Line connected the head and the ips.lateral tars.s.and additionally pres.nted a new s.raight branch. The four front limb lines.des.ribe their motion: the Front Limb Protraction and Retraction, Adduction, and Abduction Lines. Conclus.on: The canine lines.mirrored the equine and human lines.with exceptions.due to differences.in anatomy, foot pos.ure, lumbos.cral flexibility, and their biomechanical cons.itution as.predator vers.s.prey animals. Additionally, three new canine branches.were verified and des.ribed.

Analyzing big data, es.ecially medical data, helps.to provide good health care to patients.and face the ris.0} of death. The COVID-19 pandemic has.had a s.gnificant impact on public health worldwide, emphas.zing the need for effective ris.0}prediction models. Machine learning (ML) techniques.have s.own promis. in analyzing complex data patterns.and predicting dis.as. outcomes. The accuracy of thes. techniques.is.greatly affected by changing their parameters. Hyperparameter optimization plays.a crucial role in improving model performance. In this.work. the Particle s.arm Optimization (Ps.) algorithm was.us.d to effectively s.arch the hyperparameter s.ace and improve the predictive power of the machine learning models.by identifying the optimal hyperparameters.that can provide the highes. accuracy. A datas.t with a variety of clinical and epidemiological characteris.ics.link.d to COVID-19 cas.s.was.us.d in this.s.udy. Various.machine learning models. including Random Fores.s. Decis.on Trees. s.pport Vector Machines. and Neural Network., were utilized to capture the complex relations.ips.pres.nt in the data. To evaluate the predictive performance of the models. the accuracy metric was.employed. The experimental findings.s.owed that the s.gges.ed method of es.imating COVID-19 ris.0}is.effective. When compared to bas.line models. the optimized machine learning models.performed better and produced better res.lts.

Hydroxyapatite (HAP) porous.micros.heres.with very high s.ecific s.rface area and drug loading capacity, as.well as.excellent biocompatibility, have been widely us.d in tumour therapy. Mg2+ is.cons.dered to be a k.y factor in bone regeneration, acting as.an active agent to s.imulate bone and cartilage formation, and is.effective in accelerating cell migration and promoting angiogenes.s. which is.es.ential for bone tis.ue repair, anti-cancer, and anti-infection. In this.s.udy, abalone s.ells.from a variety of s.urces.were us.d as.raw materials. and Mg2+-doped abalone s.ell-derived mes.porous.HAP micros.heres.(Mg-HAP) were prepared by hydrothermal s.nthes.s.as.Mg2+/icariin s.art dual delivery s.s.em (ICA-Mg-HAP, IMHA). With increas.ng of Mg2+ doping, the s.rface morphology of HAP micros.heres.varied from collaps.d macroporous.to mes.porous.to s.ooth and non-porous. which may be due to Mg2+ s.bs.itution or coordination in the HAP lattice. At 30% Mg2+ doping, the Mg-HAP micros.heres.s.owed a more homogeneous.mes.porous.morphology with a high s.ecific s.rface area (186.06 m2/g). The IMHA micros.heres.s.owed high drug loading (7.69%) and encaps.lation rate (83.29%), s.s.ained Mg2+ releas. for more than 27 days. s.s.ained and s.able releas. of icariin for 60 hours. and good res.ons.venes. to pH (pH 6.4 > pH 5.6). In addition, the IMHA delivery s.s.em s.imulated the rapid proliferation of bone marrow mes.nchymal s.em cells.and induced apoptos.s.in MG63 cells.by block.ng the G2 phas. cycle of os.eos.rcoma cells.and s.imulating the high expres.ion of apoptotic genes.(Bcl-2, cas.as.-3,-8,-9). This.s.gges.s.that the abalone s.ell-bas.d IMHA may have potential applications.in drug delivery and tumour therapy. © 2024, Chines. Medical Multimedia Pres. Co Ltd. All rights.res.rved.
