Abstract Growth rate and meat quality, two economically important traits in pigs, are controlled by multiple genes biological pathways. In the present study, we performed a proteomic analysis of longissimus dorsi muscle from six-month-old pigs Chinese native mini-type breeds (TP DSP) introduced western (YY LL) using isobaric tag for relative absolute quantification (iTRAQ). total, 4,815 peptides corresponding to 969 proteins were detected. Comparison expression patterns between TP-DSP YY-LL...
A fiber-shaped neural probe with alterable elastic moduli allows direct implantation and enables adaptive electronic–tissue interfaces post implantation.
Aims:The Nanling Mountains are a prominent mountain range serving as natural geographical boundary in southern China and recognized one of the world's biodiversity hotspots.However, past studies on species richness have primarily focused specific taxa at localized scales.This has led to dearth research concerning comprehensive spatial patterns fauna across entire region.The objective this study is identify large-scale drivers mammalian avian offer insights support conservation Nanling's...
Abstract The effect of the place-based policies on sustainable development has received substantial attention in economic research. In China, industrial transformation and upgrading exemplary zone policy is a prominent example such policies, as it targets old resource-based cities. paper provides an early assessment policy’s capability to reduce carbon emissions. Specifically, we use data from cities for period 2012–2019 apply difference-in-differences method examine influence total...
The purpose of this study was to determine whether supplementation with lutein improved visual function in patients nonproliferative diabetic retinopathy (NPDR).In randomized, double-blind, placebo-controlled trial, 31 NPDR were assigned randomly 10 mg/d or identical placebo for 36 weeks. Visual performance indices, including acuity (VA), contrast sensitivity (CS) and glare (GS) at four different spatial frequencies, measured baseline, week 18 36.At weeks, a slight improvement VA found the...
Wheat has been widely cultivated all over the world. In China, number of approved wheat varieties steadily grown since 2010, with most notable trend in Huang-Huai-Hai region. Distinctiveness, uniformity, and stability (DUS) are prerequisites for a new variety to obtain release permit. Yet, few reports available on DUS testing characteristics released varieties. Here, 32 195 region were investigated study their artificial selection trend. The results showed that means, ranges, coefficients...
Partial differential equations (PDEs) are a common means of describing physical processes. Solving PDEs can obtain simulated results evolution. Currently, the mainstream neural network method is to minimize loss thus constraining networks fit solution mappings. By implementation differentiation, methods be divided into PINN based on automatic differentiation and other discrete differentiation. rely backpropagation, computation step time-consuming, for iterative training, complexity number...
This article investigates an optimal time-consistent reinsurance and investment problem under the mean-variance criterion for insurer whose surplus process is governed by a compound Poisson risk model. The allowed to purchase combining quota-share excess of loss claims invest in financial market increase his wealth. consists risk-free asset risky price follows jump-diffusion process. wants find reinsurance-investment strategy so as maximize expected terminal while minimizing variance...
The COVID-19 pandemic has had a huge impact on people's consumption behavior and habits. This paper takes Shanghai, China as case study uses questionnaire survey of urban residents in all districts Shanghai from April to May 2022. Herein, we empirically analyze the factors affecting shopping modes for agricultural products, describe how things have changed compared before outbreak pandemic, explore underlying mechanism. can provide policy reference ensure safety food supply context pandemic....
Abstract Active media that host spiral waves can display complex modes of locomotion driven by the dynamics those waves. We use a model photosensitive stimulus‐responsive gel supports propagation chemical to study locomotive transition and programmed locomotion. The mode between circular toroidal results from onset tip meandering arises via secondary Hopf bifurcation as level illumination is increased. This dynamic instability system introduces second with small diameter caused meandering....
In this study, polyethylene glycol (PEG) and dextran (Dex) were chemically modified to obtain amino-functionalized PEG (PEG-(NH2)2) oxidized (ODex). They subsequently reacted via -NH2 -CHO groups synthesize a macromolecular Schiff base particle. The structures, morphologies, thermal properties of the particle characterized using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetry analysis (TGA). was then employed as stabilizer stabilize...
This paper investigates a defined contribution (DC) pension plan investment problem during the accumulation phase under multiperiod mean-variance criterion. Different from most studies in literature, where investor’s risk aversion attitude is state-independent, we choose state-dependent parameter, which fractional function of current wealth level. Moreover, incorporate wage income factor into our model, leads to more complicated than portfolio selection problems that appeared relevant...
<p style='text-indent:20px;'>In reality, when facing a defined contribution (DC) pension fund investment problem, the manager may not have sufficient confidence in reference model and rather considers some similar alternative models. In this paper, we investigate robust equilibrium control-measure policy for an ambiguity-averse risk-averse manger under mean-variance (MV) criterion. The ambiguity aversion is introduced by adopting uncertainty robustness framework developed Anderson. risk...
This paper investigates the co-movement and asymmetric interactions between energy grain prices, based on evidence from crude oil corn markets, most important respectively. Time series analysis indicates that there is a consistent trend price with significant positive correlation coefficient 0.7471 during sampling period, January 2008 to February 2016. In addition, we find long-run equilibrium relationship two commodities’ prices. Moreover, while linear Granger causality tests suggest...

Using mean–variance (MV) criterion, this paper investigates a continuous-time defined contribution (DC) pension fund investment problem. The framework is constructed under Markovian regime-switching market consisting of one bank account and multiple risky assets. prices the assets are governed by geometric Brownian motion while accumulative evolves according to with drift their correlation considered. state modeled chain random assumed be independent underlying motions. incorporation...
A new risk measure fully based on historical data is proposed, from which we can naturally derive concentrated optimal portfolios rather than imposing cardinality constraints. The be expressed as a quadratics of the introduced greedy matrix, takes investors' joint behavior into account. We construct distribution‐free portfolio selection models in simple case and realistic case, respectively. latest techniques for describing transaction cost constraints solving nonconvex quadratic programs...
