摘要：Monogenic binary coding （MBC） have been known to be effective for local feature extraction, while sparse or collaborative representation based classification （CRC） has shown interesting results in robust face recognition. In this paper, a novel face recognition algorithm of fusing MBC and CRC named M-CRC is proposed; in which the dimensionality problem is resolved by projection matrix. The proposed algorithm is evaluated on benchmark face databases, including AR, PolyU-NIR and CAS-PEAL. The results indicate a significant increase in the performance when compared with state-of-the-art face recognition methods.

摘要：This paper summarizes the painting artistry from three painters： Le Van Mien, Nam Son, and Thang Tran Phenh with the following notable characteristics： realism, impressionism, and contemporary humanism. It is visible from their works that these three artists have managed to define their ways to create arts reflecting the Vietnamese people in the period of transition between 19th and 20th Century Vietnam. Contemporary humanism has always been a great aspiration to any painter in any time period. During the life and work of painters, it is the visible themes of human beings in their work that best reflect how the artists perceive life. While considered to be the pioneering figures in Vietnamese oil painting registry of art, the three painters Le Van Mien, Nam Son, and Thang Tran Phenh all happened to favor the humanism theme in their oil painting works. There were two most commonly accepted explanations for this choice. First of all, most artistic geometry lessons for beginners often choose the human figure to be the starting model for study and creative development. Secondly, during the tram-century period when Eastern and Western cultures collided in Vietnam during the late 19th early 20th Century, humans and most notably the Confucianists were the most vivid storytellers of the day and age.

摘要：To achieve the value goal of distributive justice, human society turns to the rational design and organization of social institutions. The construction of social institutions aimed at distributive justice should observe the following principles： equal opportunity, equal distribution of benefits and obligations, rational distribution criteria and procedures, and rectification of injustices. Social institutions established on these principles demonstrate inherent fairness and can ensure that social resources are distributed in an equitable way. For social institutions to ensure distributive justice is of great practical significance because this helps society integrate individuals＇ singular intentionality of pursuing distributive justice into a collective intentionality that fosters a social perspective on investigating distributive justice, establishes an egalitarian concept of distributive justice, and provides more effective protection for acts promoting distributive justice and stronger sanctions for acts undermining it. This maintains and enhances the interests of both advantaged and disadvantaged groups in distribution.

摘要：电解水是绿氢制备最有希望的路线之一,它的颈瓶是阳极析氧反应需要极高的过电位,导致电解水制氢整体能耗高.因此,迫切需要开发廉价、高活性、大电流稳定的非贵金属基多功能催化剂以期降低电解水的制氢能耗,如淡水或含尿素的水.鉴于此,我们合理设计并合成了绣球状的CoP/Ni3FeN异质结,用于碱性析氢、析氧和尿素电催化氧化反应.该催化剂呈现出优异的三功能催化活性和出色的大电流耐久性,在进行析氢、析氧和尿素电氧化反应时,分别需要-0.160、1.538和1.419 V的超低电位就能达到1000 mA cm^(-2)的高电流密度.此外,将该电催化剂作为正极和负极耦合全解水/尿素器件,仅需要1.577/1.668 V的电压就能驱动500 mA cm^(-2).此外,结合原位拉曼光谱、测试后的X射线光电子能谱分析与密度泛函理论计算,我们验证了CoP/Ni3FeN异质结催化剂可以极大地促进析氧和尿素氧化反应中的活性物种金属羟基氧化物的形成,同时降低析氢反应中的水吸附和活性氢中间体的吸附能垒,从而协同促进高效的析氢、析氧和尿素电催化氧化性能.这项工作为开发多功能电催化剂用于低电压电化学制氢提供了一条有效途径.

摘要：二维过渡金属硫族化合物(TMDCs)材料被认为是拓展摩尔定律的极具前景的候选材料.然而,该材料的低光致发光效率严重限制了其实际应用,其本质源于材料制备中不可避免引入的缺陷.在本文中,我们报道了一种Sr掺杂单层MoS_(2)的有效缺陷工程策略,该策略在实验上通过简便的化学气相沉积(CVD)一步法成功实现.所制备的具有亚毫米(~324μm)级的大尺寸样品的光致发光可实现高达两个数量级的增强,并伴随着载流子寿命的显著增强.这一现象主要归因于Sr掺杂后MoS_(2)体系中其三激子向激子转换.与此同时,掺杂样品的辐射质量和稳定性也显著提升.第一性原理计算进一步阐明了其调控机制,即在MoS_(2)中引入适当互补缺陷能级与其自身的缺陷能级协同,从而可调节其载流子组分,以实现光致发光的显著增强.此外,我们的缺陷工程策略也适用于其他掺杂剂,如钙掺杂剂.我们的工作报告了一种可以显著提升单层MoS_(2)的荧光性能的有效缺陷工程策略,这为设计和调控二维TMDCs的光电特性提供一种极具前途的方法.
