We compute the form factors for $B \to Kl^+l^-$ semileptonic decay process in lattice QCD using gauge-field ensembles with 2+1 flavors of sea quark, generated by MILC Collaboration. The span spacings from 0.12 to 0.045 fm and have multiple sea-quark masses help control chiral extrapolation. asqtad improved staggered action is used light valence quarks, clover Fermilab interpretation heavy $b$ quark. present results $f_+(q^2)$, $f_0(q^2)$, $f_T(q^2)$, where $q^2$ momentum transfer, together a...
Data augmentation is an effective solution to data scarcity in low-resource scenarios. However, when applied token-level tasks such as NER, methods often suffer from token-label misalignment, which leads unsatsifactory performance. In this work, we propose Masked Entity Language Modeling (MELM) a novel framework for NER. To alleviate the misalignment issue, explicitly inject NER labels into sentence context, and thus fine-tuned MELM able predict masked entity tokens by conditioning on their...
We present a calculation of the form factors D $\rightarrow$ Klν and $\pi$lν semileptonic decays at zero momentum transfer, ultimately for purpose determining Cabibbo-KobayashiMaskawa (CKM) matrix elements |Vcs| |Vcd|. This work uses MILC Nf = 2+1+1 configurations with HISQ action both sea quarks valence quarks, including several physical mass ensembles lattice spacings down to 0.042 fm. The is done directly q 2 0 by employing twisted boundary conditions tune child particle momenta. Results...
Using the MILC 2+1 flavor asqtad quark action ensembles, we are calculating form factors f 0 and + for semileptonic B s → Kℓv decay. A total of six ensembles with lattice spacing from ≈ 0.12 to 0.06 fm being used. At coarsest finest spacings, light mass m’ l is one-tenth strange . intermediate spacing, ratio / ranges 0.05 0.2. The valence b treated using Sheikholeslami-Wohlert Wilson-clover Fermilab interpretation. other quarks use action. When combined (future) measurements LHCb Belle II...
Considering the problems of convergence and prematurity occurred in simple genetic algorithm (SGA), an advanced was proposed. Parent individuals were replaced by elitist under certain proportion during operation selecting. The introduced to solve problem optimization Three Gorges cascade. Then simulated annealing are combined together economical Gorges. simulation results show that has greater converge speed larger probability getting best solution compared algorithm.
We report on a scale determination with gradient-flow techniques the N f = 2 + 1 HISQ ensembles generated by MILC collaboration.The lattice w 0 /a, originally proposed BMW collaboration, is computed using Symanzik flow at four spacings ranging from 0.15 to 0.06 fm.With Taylor series ansatz, results are simultaneously extrapolated continuum and interpolated physical quark masses.We give preliminary of in units, along associated systematic errors, compare other groups.We also present first...
<title>Abstract</title> Scientific evaluation of the effectiveness ecological restoration could provide support for sustainable management and protection wetlands. However due to multiple difficult quantify factors affecting wetlands, commonly used spatiotemporal methods were scientifically reflect actual restoration. This paper took Tianjin Qilihai Wetland, a representative wetland in northern China, as research object. Two time points, 2017 (before start two-years project) 2023 (four years...

The development of computers and technology has made electroacoustic music an important part modern music. In effort to broaden the musical dimension offer more possibilities for timbral combinations, composers have used various techniques combine with acoustic instruments, giving traditional instrumental a richer timbre, wider range pitches greater sonic expressiveness. pipa, typical representative Chinese culture, long history its unique timbre is widely loved by composers. This article...
Cross-user deduplication is an effective technique means to eliminate redundant uploading in using cloud storage by returning a specific response indicate existence of the data request. However, deterministic actually provides side channel attackers, which could be utilized steal privacy target storage. Because difficulty achieve complete obfuscation for chunk level deduplication, such kind attack still cannot well resisted, let alone random chunks generation attack, more sophisticated form...
Based on the features of fire and explosion accidents in petrochemical wharf storage tank area, DOW method fuzzy comprehensive evaluation were applied to evaluate risk explosion. First all, was employed hazard area preliminarily indexes various tanks obtained. Then, 5 first-level 24 second-level identified by mathematics, which entropy weight introduced determine vector arrangement analysis, an actual for a sets. On basis weighted average method, level is medium. Arranges indexes, main...
