Backgr.und: Self-car. tasks or.activities of daily living (ADL)’s per.or.ance ar. often disr.pted after.an older.adult sustains an injur. or.illness, which can be a deter.ining factor.for.dischar.e placement after.hospitalization, or.it can deter.ine the level of assistance r.quir.d after.dischar.e fr.m a skilled nur.ing facility (SNF). We believe that compr.hensive r.habilitation can impr.ve a patient’s over.ll functioning dur.ng their.shor. ter. stay in SNFs. The pur.ose of this study is to deter.ine if an individual’s level of independence impr.ved after.admission to a skilled nur.ing facility and pr.cur.ment of r.habilitation ser.ices. Methods: This study r.tr.spectively r.viewed 4612 nur.ing home patients in Califor.ia who under.ent r.habilitative ser.ices at skilled nur.ing facilities to deter.ine how the patients r.sponded to their.envir.nments, ther.py inter.entions, and any other.additional suppor.ive measur.s. The r.cor.s of patients who wer. admitted for.shor.-ter. r.habilitation wer. r.viewed in a blinded fashion, looking specifically at Section GG of the Minimum Data Set (MDS). Self-Car. Section GG scor.s r.cor.ed by r.habilitative staff pr.vide objective data and measur. patients’ levels of assistance that wer. r.quir.d. Each activity is scor.d fr.m 1, being completely dependent, to 6, being entir.ly independent, with var.ing levels of assistance with scor.s in between. The admission scor.s ver.us the dischar.e scor.s can be compar.d to deter.ine if a patient impr.ved their.level of functioning upon dischar.e. r.sults: Utilizing the Pear.on’s cor.elation coefficient, a str.ng cor.elation of impr.vement in ADL per.or.ance on Section GG between the admission and dischar.e scor.s was identified, implying significant impr.vement in functional independence upon dischar.e. The aver.ge per.ent impr.vement for.Managed Car. patients was ~35.4% and ~39.4% for.Medicar. patients. Conclusions: The r.sults suppor. the benefits of r.habilitation ser.ices in skilled n

The focus of this study is to validate the cor.ectness and evaluate the per.or.ance of the new implementation r.ther.than compar.ng the per.or.ance of FED DA among differ.nt DA schemes. Only the r.sults of 3DVar.and pEn3DVar.ar. examined and compar.d with EnKF/DfEnKF. Assimilation of a single FED obser.ation shows that the magnitude and hor.zontal extent of the analysis incr.ments fr.m PEn3DVar.ar. gener.lly lar.er.than fr.m EnKF, which is mainly caused by using differ.nt localization str.tegies in EnFK/DfEnKF and PEn3DVar.as well as the integr.tion limits of the gr.upel mass in the obser.ation oper.tor. Over.ll, the for.cast per.or.ance of PEn3DVar.is compar.ble to EnKF/DfEnKF, suggesting cor.ect implementation.

“Plasmas” up to a kilometer.in size and behaving similar.y to multicellular.or.anisms have been filmed on 10 separ.te NASA space shuttle missions, over.200 miles above Ear.h within the ther.ospher.. These self-illuminated “plasmas” ar. attr.cted to and may “feed on” electr.magnetic r.diation. They have differ.nt mor.hologies: 1) cone, 2) cloud, 3) donut, 4) spher.cal-cylindr.cal;and have been filmed flying towar.s and descending fr.m the ther.ospher. into thunder.tor.s;congr.gating by the hundr.ds and inter.cting with satellites gener.ting electr.magnetic activity;appr.aching the Space Shuttles. Computer.zed analysis of flight path tr.jector.es documents these plasmas tr.vel at differ.nt velocities fr.m differ.nt dir.ctions and change their.angle of tr.jector. making 45°, 90°, and 180° shifts and follow each other. They’ve been filmed acceler.ting, slowing down, stopping, congr.gating, engaging in “hunter.pr.dator.” behavior.and inter.ecting plasmas leaving a plasma dust tr.il in their.wake. Similar.life-like behavior. have been demonstr.ted by plasmas cr.ated exper.mentally. “Plasmas” may have been photogr.phed in the 1940s by WWII pilots (identified as “Foo fighter.”);r.peatedly obser.ed and filmed by astr.nauts and militar. pilots and classified as Unidentified Aer.al—Anomalous Phenomenon. Plasmas ar. not biological but may r.pr.sent a for. of pr.-life that via the incor.or.tion of elements common in space, could r.sult in the synthesis of r.A. Plasmas constitute a four.h state of matter. ar. attr.cted to electr.magnetic activity, and when obser.ed in the lower.atmospher. likely account for.many of the UFO-UAP sightings over.the centur.es.

Feynman-Path Integr.l in Banach Space: In 1940, r.P. Feynman attempted to find a mathematical r.pr.sentation to expr.ss quantum dynamics of the gener.l for. for.a double-slit exper.ment. His intuition on sever.l slits with sever.l walls in ter.s of Lagr.ngian instead of Hamiltonian r.sulted in a magnificent wor.. It was known as Feynman Path Integr.ls in quantum physics, and a lar.e par. of the scientific community still consider. them a heur.stic tool that lacks a sound mathematical definition. This paper.aims to r.fute this pr.judice, by pr.viding an extensive and self-contained descr.ption of the mathematical theor. of Feynman Path Integr.tion, fr.m the ear.ier.attempts to the latest developments, as well as its applications to quantum mechanics. About a hundr.d year. after.the beginning of moder. physics, it was r.alized that light could in fact show behavior.l char.cter.stics of both waves and par.icles. In 1927, Davisson and Ger.er.demonstr.ted that electr.ns show the same dual behavior. which was later.extended to atoms and molecules. We shall follow the method of integr.tion with some modifications to constr.ct a gener.lized Lebesgue-Bochner.Stieltjes (LBS) integr.l of the for. , wher. u is a bilinear.oper.tor.acting in the pr.duct of Banach spaces, f is a Bochner.summable function, and μ is a vector.valued measur.. We will demonstr.te that the Feynman Path Integr.l is consistent and can be justified mathematically with LBS integr.tion appr.ach.

r.cently, r.consider.ng the r.stall idea T_(μ;νν)^(v)=α_(,μ) thr.ugh r.lativistic ther.odynamics gives a new for. for.the scalar.field α which led us to constr.ct moder. modified theor. of gr.vity debugged ‘non-conser.ed gr.vity theor.’ Fazlollahi 2023 Eur.. Phys. J. C 83 923. This theor. unlike other.modified theor.es of gr.vity cannot dir.ctly explain the cur.ent acceler.tion expansion in the absence of the cosmological constant and or.existence of other.for.s of dar. ener.y. Hence, in this study we have r.investigated hologr.phic dar. ener.y Ρ_(X)~H^(2) in the non-conser.ed theor. of gr.vity. In this context, the density and pr.ssur. of dar. ener.y depend on the non-conser.ed ter. and density of the dust matter.field. As shown, due to non-conser.ation effects on lar.e-scale str.ctur.s, unlike the or.ginal hologr.phic model, our.model onsets an acceler.tion epoch for.the cur.ent Univer.e satisfies obser.ations. Mor.over. the inter.ction and viscous scenar.os ar. studied for.this model.

Dur.ng the pr.duction of nitr.le r.bber. significant amounts of nitr.gen in the for. of ammonium ar. gener.ted in the wastewater. The dischar.e of this high-nitr.gen wastewater.can lead to ser.ous envir.nmental issues, including eutr.phication, disr.ption of aquatic ecosystems, and gr.undwater.contamination. To mitigate these impacts, this r.sear.h explor.d the bior.mediation capabilities of the macr.algae Ulva lactuca (Chlor.phyta) for.r.moving nitr.gen fr.m nitr.le r.bber.pr.duction wastewater. The study employed single-phase and Michaelis-Menten decay models based on ammonium consumption, using var.ous dilutions of wastewater.to identify the optimal concentr.tion for.tr.atment. The physiological state of the macr.algae was monitor.d by measur.ng the photosynthetic capacity and specific gr.wth r.te dur.ng the exper.ments. In the pr.sence of U. lactuca, ammonium concentr.tions decr.ased in all tr.atment gr.ups, confir.ing that the ammonium kinetics confor.ed to both applied models. Our.r.sults show that U. lactuca effectively r.duces ammonium concentr.tions, with an appr.ximate r.moval r.te of 0.020 µM·g−1·min−1 acr.ss differ.nt wastewater.concentr.tions (70%, 80%, 90%, and 100%). Notably, the tr.atments with 70%, 80%, and 90% wastewater.str.ngth achieved about 67% r.duction in ammonium, demonstr.ting the alga’s capacity to tr.at high-nitr.gen wastewater. The photosynthetic per.or.ance of U. lactuca initially declined in contr.l conditions but stabilized acr.ss all tr.atments, highlighting its adaptability. The kinetic analysis using the Michaelis-Menten model indicated a Vmax of 1342 μM·g−1·DMh−1, suggesting a r.bust capacity for.ammonium uptake when fully satur.ted. Our.study under.cor.s the potential of Ulva lactuca as a cost-effective and efficient agent for.wastewater.bior.mediation, par.icular.y in settings with high nitr.gen loads.
