One objective of developing machine learning(ML)-based material models is to integrate them with well-established numerical methods to solve boundary.value problems(BVPs).In the family.of ML models,recurrent neural networks(RNNs)have been extensively.applied to capture history.dependent constitutive responses of granular materials,but these multiple-step-based neural networks are neither sufficiently.efficient nor aligned with the standard finite element method(FEM).Single-step-based neural networks like the multi-lay.r perceptron(MLP)are an alternative to by.ass the above issues but have to introduce some internal variables to encode complex loading *** this work,one novel Frobenius norm-based internal variable,together with the Fourier lay.r and residual architectureenhanced MLP model,is crafted to replicate the history.dependent constitutive features of representative volume element(RVE)for granular *** obtained ML models are then seamlessly.embedded into the FEM to solve the BVP of a biaxial compression case and a rigid strip footing *** obtained solutions are comparable to results from the FEM-DEM multiscale modelling but achieve significantly.improved *** results demonstrate the applicability.of the proposed internal variable in enabling MLP to capture highly.nonlinear constitutive responses of granular materials.

To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sample, distributed among 41 center-of-mass energy.points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the y.ar 2010. By.analy.ing the large angle Bhabha scattering events, we measure the integrated luminosity.of the data sample at each center-of-mass energy.point. The total integrated luminosity.of the data sample is 76.16±0.04±0.61 pb^-1, where the first uncertainty.is statistical and the second sy.tematic.

The evaluation from prospective cohort studies on the dietary.ω-3 long-chain poly.nsaturated fatty.acid (LCPUFA) supplementation and nutritional value is consistent. However, the effect of different ty.es of ω-3 long-chain PUFA (ω-3 LCPUFA) on microbiota in intestine is inconsistent. In this study. the mice were divided into three groups (N, PL, FO), with AIN-93M (N), AIN-93M + Phospholipids ty.e ω-3 LCPUFA (PL) and AIN-93M + trigly.eride ty.e ω-3 LCPUFA (FO), respectively. Denaturing Gradient Gel Electrophoresis (DGGE) was used to detect the structure of intestinal microbiota. The data showed that the composition of gut microbiota was changed by.treating with the two ty.es of ω-3 LCPUFA. The results revealed that gut microbiota’ enrichment in FO group was decreased while in PL group was increased. The data also showed that the histological morphology.of the small intestine in treated mice was improved especially.in group PL, which was much more significant and suggested that Phospholipids ty.e ω-3 LCPUFA is beneficial to intestinal health.

The current study.was to investigate the effects of cy.teamine （CS） on carcass characteristics, meat quality. and antioxidant status in finishing pigs. A total of 24 crossbred （PIC variety. finishing pigs （60.05±1.24 kg, 12 gilts and 12 barrows） were assigned randomly.to one of the three dietary.groups, with four pens/group （one gilt and one barrow per pen）. Pigs were fed with a basal diet containing 0 （control）, 70, or 140 mg/kg CS for 47 day.. The results indicated that dietary.CS supplementation increased （P〈0.05） the average daily.gain and feed intake with optimal responses occurring at 70 mg/kg. Dietary.supplementation of CS increased （P〈0.05） the dressing percentage and lean percentage of finishing pigs with optimal responses occurring at 140 mg/kg. The CS supplementation, however, had no effect （P〉0.05） on meat quality. Dietary.CS supplementation increased （P〈0.05） total antioxidant capacity.（T-AOC） and decreased malondialdehy.e （MDA） with optimal responses occurring at 70 mg/kg. CS supplementation at both 70 mg/kg and 140 mg/kg doses improved （P〈0.05） the muscle RNA/DNA ratio. Collectively. the results suggest dietary.supplementation of 70 mg/kg CS could significantly.improve growth performance and antioxidant status without adverse effects on the gastrointestinal tracts in finishing pigs while the 140 mg/kg CS supplementation improved the carcass quality. However, meat quality.was not affected by.CS supplementation.
