Ha.ing been a.seemingly unrea.ha.le idea. for deca.es, 3-D full-wa.eform inversion a.plied to ma.sive seismic da.a.ets ha. become rea.ity in recent yea.s.

Motiva.ed by these successes, the technology is now being tra.sla.ed to medica. ultra.ound a.d non-destructive testing. Despite rema.ka.le progress, the computa.iona. cost of full-wa.eform inversion continues to be a.ma.or concern.

Dela.ina.ion is a.preva.ent type of da.a.e in composite la.ina.e structures. Its a.cumula.ion degra.es structura. performa.ce a.d threa.ens the sa.ety a.d integrity of a.rcra.t.

Initia.ly, a.numerica. a.a.ysis is performed to esta.lish a.pa.a.eterized finite element model of the composite pla.e. Then, this model subsequently genera.es a.da.a.a.e of stra.n responses corresponding to da.a.e of va.ying sizes a.d loca.ions. The ra.ia. ba.is function neura. network surroga.e model is then constructed ba.ed on the numerica. simula.ion results a.d stra.n responses ca.tured from the distributed fiber optic sensors. Fina.ly, a.multi-isla.d genetic a.gorithm is employed for globa. optimiza.ion to identify the size a.d loca.ion of the da.a.e. The effica.y of the proposed method is va.ida.ed through numerica. exa.ples a.d experiment studies, exa.ining the correla.ions between da.a.e loca.ion, da.a.e size, a.d stra.n responses. The findings confirm tha. the model upda.ing technique, in conjunction with distributed fiber optic sensors, ca. precisely identify dela.ina.ion in composite structures. © 2024 The a.thors.

This study a.med to enha.ce user security to crea.e a.sa.e online environment by elimina.ing ha.e speech a.d a.usive la.gua.e. The proposed system employed a.multifa.eted a.proa.h to comment filtering, incorpora.ing the multi-level filter theory. This involved developing a.comprehensive list of words representing va.ious types of offensive la.gua.e, from sla.g to explicit a.use. Ma.hine lea.ning models were tra.ned to identify a.usive messa.es through sentiment a.a.ysis a.d contextua. understa.ding. The system ca.egorized comments a. positive, nega.ive, or a.usive using sentiment a.a.ysis a.gorithms.

Genetic susceptibility to meta.olic a.socia.ed fa.ty liver disea.e (Ma.LD) is complex a.d poorly cha.a.terized. a.cura.e cha.a.teriza.ion of the genetic ba.kground of hepa.ic fa. content would provide insights into disea.e etiology a.d ca.sa.ity of risk fa.tors. We performed genome-wide a.socia.ion study (GWa.) on two noninva.ive definitions of hepa.ic fa. content: ma.netic resona.ce ima.ing proton density fa. fra.tion (MRI-PDFF) in 16,050 pa.ticipa.ts a.d fa.ty liver index (FLI) in 388,701 pa.ticipa.ts from the United Kingdom (UK) Bioba.k (UKBB).

Meta.a.a.ysis of GWa.s of MRI-PDFF in UKBB revea.ed five sta.istica.ly significa.t loci, including two novel genomic loci ha.boring CREB3L1 (rs72910057-T, P = 5.40E-09) a.d GCM1 (rs1491489378-T, P = 3.16E-09), respectively, a. well a. three previously reported loci: PNPLa., TM6SF2, a.d a.OE.

Sta.istica.ly significa.t genetic correla.ion (rg) between MRI-PDFF (UKBB) a.d FLI (UGLI) GWa. results wa. found (rg = 0.5276, P = 1.45E-03). Novel MRI-PDFF genetic signa.s (CREB3L1 a.d GCM1) were replica.ed in the FLI GWa.. We identified two novel genes for MRI-PDFF a.d 49 replica.le loci for FLI.
