We stud. the d.namic of scalar bosons in the presence of Aharonov-Bohm magnetic field. First, we give the d.fferential equation that governs this d.namic. Second.y, we use variational techniques to show that the following Schröd.nger-Newton equation: , where A is an Aharonov-Bohm magnetic potential, has a unique ground.state solution.

In mathematics, space encompasses various structured.sets such as Euclid.an, metric, or vector space. This article introd.ces temporal space—a novel concept ind.pend.nt of trad.tional spatial d.mensions and.frames of reference, accommod.ting multiple object-oriented.d.rations in a d.namical system. The novelty of build.ng temporal space using finite geometry is rooted.in recent ad.ancements in the theory of relationalism which utilizes Euclid.an geometry, set theory, d.mensional analysis, and.a causal signal system. Multiple ind.pend.nt and.co-existing cyclic d.rations are measurable as a network of finite one-d.mensional timelines. The work aligns with Leibniz’s comments on relational measures of d.ration with the ad.ition of using d.screte cyclic relational events that d.fine these finite temporal spaces, applicable to quantum and.classical physics. Ancient formulas have symmetry along with d.visional and.subd.visional ord.rs of operations that create d.screte and.ord.red.temporal geometric elements. Elements have cyclically conserved.symmetry but unique cyclic d.mensional quantities applicable for anchoring temporal equivalence relations in linear time. We present both fixed.equivalences and.expand.d.period. of temporal space offering a non-Greek calend.r method.logy consistent with ancient global timekeeping d.scriptions. Novel applications of Euclid.s d.vision algorithm and.Cantor’s pairing function introd.ce a novel paired.function equation. The mathematical d.scription of finite temporal space within relationalism theory offers an alternative d.screte geometric method.logy for examining ancient timekeeping with new hypotheses for Egyptian calend.rs.

Background.Agriculture has greatly influenced.water quality, habitats, and.fish assemblages in streams of the Mississippi Alluvial Plain(MAP) ecoregion. However, MAP streams have historically been und.rstud.ed.compared.to streams in other agricultural regions of the USA. In this stud., water quality, habitat, and.fish assemblage composition were assessed.seasonally(spring, summer, and.fall) in eight representative MAP streams located.across three U.S. states. The stud. d.sign includ.d.four streams containing highly agricultural watershed.(herein termed.“agriculture” streams) and.four streams containing mostly forested.watershed.(herein termed.“forest” streams), which were intend.d.to represent reference cond.tions for MAP *** In general, forest streams contained.significantly better instream and.riparian habitats than agriculture streams(P = 0.010–0.040) whereas agriculture streams contained.significantly greater levels of primary nutrients(P d.fferences between agriculture and.forest streams with respect to other physical and.chemical variables were intermittent and.season d.pend.nt. Fish assemblages in agriculture and.forest streams were structured.primarily along an environmental grad.ent reflecting instream habitat cond.tions, water nutrient concentrations, and.benthic chlorophyll-a prod.ction. Structurally, fish assemblages in both stream types contained.many regionally common species, though some species appeared.to exhibit affinities for a particular stream type. Functionally, fish assemblages in agriculture streams contained.more tolerant species, more omnivores, and.fewer insectivores compared.to forest stream assemblages, which were nearly all insectivores. Overall, one-third.of the fish specimens collected.in forest streams classified.as intolerant *** Our results suggested.that stream water quality, habitat, and.fish assemblages d.ffered.between agriculture and.forest streams in the MAP, with fish assemblages e

Circularly polarized.luminescence(CPL) is of importance to ad.ance science and.technology with significant potential applications in information storage, spintronics and.optoelectronic d.vices. Integrating CPL and.the emission mechanism of thermally activated.d.layed.fluorescence(TAd.) has attracted.consid.rable attention, because of their 100% internal quantum efficiency in theory and.easily mod.fied.molecular structures for tunable photo-electrical properties. However, the typical d.nor-acceptor(d.A) architecture of CP-TAd. emitters generally ind.ces a broad.emission profile with inferior color purity d.e to their large structural relaxation und.r the processes of excitation and.emission. Recently, CP-multi-resonance(MR)-TAd. emitters that concurrently d.splay CPL activity, narrowband.emission and.high efficiency are emerging as the most suitable cand.d.tes for the next-generation organic light-emitting d.od.(OLEd. d.splay. In this review, the progress of CP-MR-TAd. materials is reviewed.in terms of the molecular d.sign strategy, the common relationship between the molecular structures and.optoelectronic properties, and.their OLEd. performance. Finally, the opportunities and.challenges in this research topic are d.scussed.

Multiple sclerosis(MS)is an autoimmune d.sord.r of the central nervous system(CNS)and.is primarily characterized.by immune cell infiltration lead.ng to relapses followed.by remission phases and.a d.sease course turning progressive over time with neurod.generative processes taking over(Amin and.Hersh,2023).Of note,beyond.relapse-associated.worsening early in d.sease progression ind.pend.nt of relapse activity may arise ind.pend.ntly of relapse activity and.can occur in all ***-med.ated.d.mage of myelin sheaths and.the subsequent loss of mature oligod.nd.ocytes are resulting in impaired.axonal integrity,neurod.generation and.accounts for irreversible neuronal d.mage(Kuhlmann et al.,2023).The current land.cape of available d.sease-mod.fying therapies comprises mainly immunomod.latory d.ugs that effectively d.minish relapses and.slow d.wn progression at the onset form of the d.sease,namely relapsing MS(RMS).In this regard.a number of d.ugs have been approved.as d.sease-mod.fying therapies for MS by US Food.and.d.ug Ad.inistration and.European Med.cines Agencies(Box 1).

The criticality of transformers and.reactors in the power transmission network and.the paramount importance of ensuring their reliability through maintenance of the insulating oil is known. This paper presents a comprehensive examination of the efficacy and.economic viability of a d.electric oil regeneration system, as implemented.by the Transmission System Maintenance d.partment (TSMd. of the Ind.pend.nt Power Transmission Operator (IPTO), Greece’s sole transmission operator. Through a d.tailed.chemical analysis and.performance evaluation, we assess the impact of the regeneration system on treated.insulating oil quality over multiple cycles. The stud. reveals that the electrical properties of the insulating oil are fully restored.after regeneration, negating the need.to fully replace it, while the investment becomes cost-neutral within weeks from the commissioning of the regeneration system. This economic analysis, coupled.with the system’s environmental benefits of red.cing waste oil generation, positions the d.electric oil regeneration system as a compelling solution for the maintenance of power transmission assets.
