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.

作者： Steven d. P. Moore Ind.pend.nt Researcher Milton Canada

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 timek.eping 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 timek.eping with new hypotheses for Egyptian calend.rs.

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 k.own. 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 week. 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.
