This study aimed to investigate the effects of different proportions of dietary fermented sweet potato residue(FSPR) supplementation as a substitute for corn on the nutrient digestibility, meat quality, and intestinal microbes of yellow-feathered broilers. Experiment 1(force-feeding) evaluated the nutrient composition and digestibility of mixtures with different proportions of sweet potato residue(70%, 80%,90%, and 100%) before and after fermentation. In Experiment 2(metabolic growth), a total of 420 oneday-old yellow-feathered broilers were randomly allocated to 4 groups and fed corn-soybean mealbased diets with 0, 5%, 8%, and 10% FSPR as a substitute for corn. The force-feeding and metabolic growth experiments were performed for 9 and 70 d, respectively. The treatment of 70% sweet potato residue(after fermentation) had the highest levels of crude protein, ether extract, and crude fiber and improved the digestibility of crude protein and amino acids(P < 0.05). Although dietary FSPR supplementation at different levels had no significant effect on growth performance and intestinal morphology, it improved slaughter rate, half-chamber rate, full clearance rate, and meat color, as well as reduced cooking loss in the breast and thigh muscles(P < 0.05). Dietary supplementation with 8% and 10% FSPR increased the serum immunoglobulin M and immunoglobulin G levels in broilers(P < 0.05). Furthermore, 10% FSPR increased the Shannon index and Ruminococcaceae＿UCG-014, Ruminococcaceae＿UCG-010 and Romboutsia abundances and decreased Sutterella and Megamonas abundances(P < 0.05). Spearman's correlation analysis showed that meat color was positively correlated with Ruminococcaceae＿UCG-014(P < 0.05) and negatively correlated with Megamonas(P < 0.05). Collectively, 70% sweet potato residue(after fermentation) had the best nutritional value and nutrient digestibility. Dietary supplementation with 8% to 10%FSPR as a substitute for corn can improve the slaughter performance, meat quality

支持等式测试的标识加密(identity-based encryption with equality test, IBEET)体制解决了传统等式测试方案中证书管理的问题,得到了广泛的关注.但现有的IBEET体制难以抵抗渗透攻击,且都是基于国外密码算法设计,不具有自主知识产权.基于此,提出一种支持等式测试并具有密码逆向防火墙的SM9标识加密方案(SM9 identity-based encryption scheme with equality test and cryptographic reverse firewalls, SM9-IBEET-CRF).该方案在用户与云服务器的上行信道间部署密码逆向防火墙(cryptographic reverse firewalls,CRF),对用户发出的信息执行重随机化以达到抵抗渗透攻击的作用.该方案拓展国密算法SM9至IBEET领域中,提升其运行效率并丰富国密算法在云计算领域的研究.给出了SM9-IBEET-CRF的形式化定义和安全模型,并在随机预言机模型中考虑2种不同的敌手将此方案在选择密文攻击下的不可区分性与单向性分别形式化地规约到BDH困难假设上.同时,该方案通过考虑第3种敌手证明CRF的部署为其带来维持功能性、保留安全性以及抵抗渗透性.实验仿真和分析结果展示了该方案的有效性.

数字经济下数字技术如何影响数字贸易是现有研究关注的热点,但对人工智能如何影响数字贸易研究不足。利用斯坦福大学的人工智能指数并结合各数字服务行业数据强度构建“出口国一进口国一行业一年份”维度的人工智能应用水平指标,围绕2017一2020年主要国家人工智能应用水平对其数字服务出口的影响展开理论剖析与实证研究。研究表明:无论是出口国还是进口国,人工智能应用对促进数字服务出口都具有正向影响,在一系列稳健性与内生性检验后结果依然稳健。异质性分析发现,与一国基于经济层面的人工智能创新发展贸易效应相比,基于人工智能研发层面的贸易促进效应更显著,其中人工智能出版物的创新知识外溢效应比人工智能专利申请具有更强的数字服务出口促进作用,人工智能人力资本的出口促进作用最弱;除此,人工智能应用对不同性质的数字服务行业贸易出口均有促进作用。机制检验显示,人工智能会通过提升生产率水平与削减贸易成本影响数字服务出口。本文可为促进人工智能创新发展、推动人工智能与数字服务贸易深度融合提供政策参考。

当下的中国正处于近代以来最好的发展时期,但也存在科技基础薄弱、原始创新能力不足等问题,因而促发社会经济发展对双创教育的现实需求。我国高校的双创教育虽然实现了外延式发展,但也面临着“四不”困境,即:不融合,双创教育与专业教育融合度不够;不自由,学生开展双创学习及探究缺乏自由度;不纯粹,人文精神缺失及工具理性导致双创实践的功利性;不适应,激发学生双创实践的文化环境匮乏。究其原因,与双创教育理念是一种经济行为还是创新行为,教育理论指导是借鉴外来还是本土自建,人才培养体系是重构还是传统模式的修补,内部运行维度的动力来源于内部还是外部等有关。双创教育未来选择应坚持文化自信,注重价值引导,优化课程体系,改革教育方式,培育双创文化,实现双创教育高质量发展。
