The development of an efficient artificial H_(2)O_(2)photosynthesis system is a challenging work using H_(2)O and O_(2)as starting ***,3D In2.77S_(4)nanoflower precursor was in-situ deposited on K^(+)-doped g-C_(3)N_(4)(KCN)nanosheets using a solvothermal method,then In2.77S_(4)/KCN(IS/KCN)het-erojunction with an intimate interface was obtained after a calcination *** investigation shows that the photocatalytic H_(2)O_(2)production rate of 50IS/KCN can reach up to 1.36 mmol g^(-1)h^(-1)without any sacrificial reagents under visible light irradiation,which is 9.2 times and 4.1 times higher than that of KCN and In2.77S_(4),*** enhanced activity of the above composite can be mainly attributed to the S-scheme charge transfer route between KCN and In2.77S_(4)according to density functional theory calculations,electron paramagnetic resonance and free radical capture tests,leading to an expanded light response range and rapid charge separation at their interface,as well as preserving the active electrons and holes for H_(2)O_(2)***,the unique 3D nanostructure and surface hydrophobicity of IS/KCN facilitate the diffusion and transportation of O_(2)around the active centers,the energy barriers of O_(2)protonation and H_(2)O_(2)desorption steps are ef-fectively reduced over the *** addition,this system also exhibits excellent light harvesting ability and *** work provides a potential strategy to explore a sustainable H_(2)O_(2)photo-synthesis pathway through the design of heterojunctions with intimate interfaces and desired reac-tion thermodynamics and kinetics.

研究了基于游离病毒和细胞–细胞两种传播机制和适应性免疫的多时滞HIV动力学模型,计算出模型存在五个平衡点和五个基本再生数。通过构造适当的Lyapunov函数,得到了模型的五个平衡点全局渐近稳定的充分条件。发现将一个时滞τ_(3)作为分支参数,可引起两个平衡点E_(2)和E_(4)失稳,并产生Hopf分支。结果说明τ_(3)可导致病毒载量出现周期振荡和免疫反应可降低感染风险。最后利用数值模拟验证所得结论,并对比了不同时滞参数对E_(2)和E_(4)的稳定性影响。

附着龈与游离龈相连续,均为角化上皮,两者合称为角化龈。附着龈紧紧附于牙槽骨,质地坚韧,抵抗力强,对于牙周健康具有重要意义。在临床上,附着龈不足或者缺失会造成一系列问题,如咀嚼过程中龈缘受到摩擦或肌肉牵引后与牙面分离,从而导致食物残渣等进入龈沟,造成牙周破坏;此外,在修复体、种植体边缘会导致患者咀嚼过程中出现疼痛;对于可摘局部义齿而言,还会影响义齿设计和患者佩戴,影响患者生活质量。可见,附着龈不足或缺失已成为牙周、修复、种植等多学科共同面临的问题。针对其治疗,目前涉及的方法主要有自体软组织移植和生物替代材料两大类。本综述旨在探讨各种附着龈增宽治疗方式的特点,为临床工作提供理论依据,为进一步研究提供参考。

人口老龄化不断加深是经济社会发达到一定程度的普遍现象,对中国消费结构有着深远影响。本文主要通过中国省级面板数据实证分析人口老龄化对消费结构的影响效果和作用路径。研究结果显示:(1)随着人口老龄化程度的加深,老龄化对中国消费结构存在倒“U”型影响;(2)人口老龄化对东部地区的消费结构没有显著性影响,对中部、西部以及东北地区的消费结构改善存在一定的负向影响;(3)产业结构和人力资本水平对人口老龄化与消费结构的影响具有正向调节效应。基于此,本文对中国人口老龄化问题和消费结构改善提出相应的改进措施,以供参考。

在全球经济增长放缓的形势下,为尽快恢复经济复苏增长并推动国内大循环,加快实现国内国际双循环发展就离不开对居民有效消费需求的引导及其消费潜力的释放。近年来,以大数据、5G、人工智能为依托的经济数字化转型已深刻影响社会的各个层面,作为拉动国民经济增长重要引擎的消费领域自然也受到其深刻影响。文章基于2017—2021年全国主要99个地级市的面板数据,通过实证分析探讨数字经济发展对居民消费潜力及其各维度的作用效果和溢出效应。结果表明:(1)数字经济发展对居民消费潜力及其消费支出维度、消费收入维度和消费环境维度均有积极作用;(2)数字经济对促进居民消费潜力释放具有正向的空间溢出效应;(3)相对居民消费潜力中的收入和支出维度,数字经济对居民消费环境维度的正向空间溢出效应更加明显。
