多酚是存在于植物性食物中的一类化合物,具有抗氧化、抗炎和抗肿瘤等生物活性。然而,在食品加工、储藏和消化的过程中,多酚容易遭受外界不利因素(如高温、光照、碱性环境等)的影响而降低甚至丧失生物活性。淀粉基凝胶体系不仅具有天然来源多糖类物质良好的生物相容性、可降解性和安全性,而且自身三维网络结构对小分子表现出优异的包封能力和有效的控释作用。近年来,通过不同方式(如3D打印、共价或非共价交联以及作为凝胶填充物)所构建的淀粉基凝胶,在提高多酚类小分子活性成分的稳定性和生物利用率等方面表现出较大的应用前景。本文首先介绍了多酚的生物活性以及自身的局限性,着重探讨了淀粉自身的特性(如糊化、老化、胶凝性等)以及不同交联方式与淀粉基凝胶形成之间的联系,进一步分析了多酚在淀粉基凝胶形成中的作用,以及所构建的淀粉基凝胶对多酚封装和释放性能的影响,在此基础上,对淀粉基凝胶-多酚体系在食品中的应用前景和挑战进行了展望。

To protect superconducting qubits and enable rapid readout, optimally designed Purcell filters are essential. To suppress the off-resonant driving of untargeted readout resonators, individual Purcell filters are used for each readout ***, achieving consistent frequency between a readout resonator and a Purcell filter is a significant challenge. A systematic computational analysis is conducted to investigate how fabrication variation affects filter performance, through focusing on the coupling capacitor structure and coplanar waveguide(CPW) transmission line specifications. The results indicate that the T-type enclosing capacitor(EC), which exhibits lower structural sensitivity, is more advantageous for achieving target capacitance than the C-type EC and the interdigital capacitor(IDC). By utilizing a large-sized CPW with the T-type EC structure, fluctuations in the effective coupling strength can be reduced to 10%, given typical micro-nanofabrication variances. The numerical simulations presented in this work minimize the influence of fabrication deviations, thereby significantly improving the reliability of Purcell filter designs.

近年来,我国实施了新一轮大豆扩种政策。在一系列“超常规”措施推动下,2022年大豆产量大幅增加。但通过对东北地区的调研发现,大豆价格高开低走,豆农收益低于预期,在国储和省储的助力下,产销衔接基本平稳;但本地大豆加工企业开工率低,农户种植大豆的积极性不高。在大豆和玉米“双短缺”的背景下,进一步扩种大豆的风险和挑战加剧,需要引起高度重视。为此,扩种大豆政策不能仅在种植环节发力,更需要在整个产业链上协同推进,构建长效政策机制。在稳存量、增储备、促加工的发展思路基础上,应通过扩种速度缓一些、收储规模增一些、加工转化多一些来化解相应风险。

国家自然科学基金委员会是资助数学研究的重要部门之一,自成立以来已资助中国数学学科项目超过22000项,其中青年科学基金项目超过8600项.研究数学学科青年科学基金项目的申请和资助情况,有助于了解我国数学青年人才发展规模.论文利用数据科学的技术,首先对青年科学基金项目的申请资助情况进行整体分析,并按照学科、年龄、院校、性别等因素对项目资助率进行分层透视.针对近些年青年科学基金整体“量增率减”的现象,论文第三部分利用统计学的方法从申请人的维度分析资助比例的变化规律.针对已获青年项目立项者继续申请面上项目的情况,论文通过引入删失数据机制和Kaplan-Meier生存曲线方法,推断出青年项目立项距面上项目获批的间隔时长分布,得到了间隔时长的更准确的均值和分位数估计,有效解决了只考虑已获批面上项目者将导致的“抽样偏差”问题.
