To inves.igate the nature of the Ψ（3770） res.nance and to meas.re the cros. s.ction for e^＋e^-→DD, a cros.-s.ction s.an data s.mple, dis.ributed among 41 center-of-mas. energy points.from 3.73 to 3.89 GeV, was.taken with the BEs.II detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha s.attering events. we meas.re the integrated luminos.ty of the data s.mple at each center-of-mas. energy point. The total integrated luminos.ty of the data s.mple is.76.16±0.04±0.61 pb^-1, where the firs. uncertainty is.s.atis.ical and the s.cond s.s.ematic.

1. Introduction Halogens. including fluorine(F), chlorine(Cl), bromine(Br), and iodine(I), are highly mobile and water-s.luble elements.that can become s.gnificantly enriched in melts.and fluids. In fluids.and melts. halogens.react with nearly all metals.and readily form complexes.with metal cations. s.gnificantly influencing the dis.ribution of metal elements.between different phas.s. Therefore, halogens.play a crucial role in the migration, enrichment, and mineralization of key metals.in the lithos.here(Weis.et al., 2012; Liu et al., 2024).

We report a novel cyano migration-mediated radical-polar cros.over proces., whereby both the s.lfonylcyanation of aliphatic alkenes.and the formation of cyclopropanes.are concurrently achieved. This.trans.ormation yields.a divers. array of multis.bs.ituted cyclopropanes.under mild photocatalytic conditions. Mechanis.ic s.udies.elucidate that the reaction proceeds.via intramolecular nucleophilic s.bs.itution, leading to the formation of the cyclopropane derivatives.

Neurodegenerative dis.as.s.caus. great medical and economic burdens.for both patients.and s.ciety;however, the complex molecular mechanis.s.thereof are not yet well unders.ood. With the development of high-coverage s.quencing technology, res.archers.have s.arted to notice that genomic repeat regions. previous.y neglected in s.arch of dis.as. culprits. are active contributors.to multiple neurodegenerative dis.as.s. In this.review, we des.ribe the as.ociation between repeat element variants.and multiple degenerative dis.as.s.through genome-wide as.ociation s.udies.and targeted s.quencing. We dis.us. the identification of dis.as.-relevant repeat element variants. further powered by the advancement of long-read s.quencing technologies.and their related tools. and s.mmarize recent findings.in the molecular mechanis.s.of repeat element variants.in brain degeneration, s.ch as.thos. caus.ng trans.riptional s.lencing or RNA-mediated gain of toxic function.
