Asymmetry of Left Versus Right Lateral Face in Face Recognition

Prior research has found that the left side of the face is emotionally more expressive than the right side [1]. This was demonstrated in a study where the right and the left halves of a face image were combined with their mirror-reversed duplicates to make composite images. When observers were asked which composite face appeared more emotional, they selected the left-left over the right-right composite more often

The Research on Influence of the Acquaintance Between Teachers and Students on Students’ Learning Effect in Dialogue Teaching

The acquaintance between teachers and students is one of the important factors that affects the quality of dialogue teaching. Previous researches that are did by experts focus on the effect of students’ acquaintance mostly, but there is less research on the dependent variable of the acquaintance between teachers and students. In the study, the data were collected through teacher-student interview, supernova questionnaire survey and teacher-student interaction recording in class, and the relevant experimental data were analyzed in a quantitative way. Through the analysis of experimental data, it is found that the acquaintance between teachers and students is an important factor that affects the teaching effect, and the influence on each teaching dimension is not consistent. The results show that the close interaction that is produced between teachers and students in the class can promote the emotional communication between teachers and students, it has a positive impact on the knowledge communication and interactive experience between teachers and students, but the communication between teachers and students will also bring related adverse effects to the teaching effect. Therefore, it shows that the influence that teacher-student acquaintance exerts to the teaching effect is uncertain

Experimental Investigation on the Joining of Aluminum Alloy Sheets Using Improved Clinching Process

Aluminum alloy sheets have been widely used to build the thin-walled structures by mechanical clinching technology in recent years. However, there is an exterior protrusion located on the lower sheet and a pit on the upper sheet, which may restrict the application of the clinching technology in visible areas. In the present study, an improved clinched joint used to join aluminum alloy sheets was investigated by experimental method. The improved clinching process used for joining aluminum alloy evolves through four phases: (a) localized deformation; (b) drawing; (c) backward extrusion; and (d) mechanical interlock forming. A flat surface can be produced using the improved clinching process. Shearing strength, tensile strength, material flow, main geometrical parameters, and failure mode of the improved clinched joint were investigated. The sheet material was compressed to flow radially and upward using a punch, which generated a mechanical interlock by producing severe localized plastic deformation. The neck thickness and interlock of the improved clinched joint were increased by increasing the forming force, which also contributed to increase the strength of the clinched joint. The improved clinched joint can get high shearing strength and tensile strength. Three main failure modes were observed in the failure process, which were neck fracture mode, button separation mode, and mixed failure mode. The improved clinched joint has better joining quality to join aluminum alloy sheets on the thin-walled structures

Core human values and their interactions with pro-Tobacco factors on cigarette smoking: The role of factors not explicitly related to a risk behavior

More effective tobacco control requires new data on factors that are not explicitly related to smoking but are influential, such as “Terminal Values” regarding desirable end-states of existence and “Instrumental Values” regarding desirable modes of conduct. Association analysis was conducted among 36 Core Values (18 Terminal and 18 Instrumental) derived from Rokeach’s Value Survey, three risk factors (protobacco media, smoking peers and sensation-seeking), and cigarette smoking using data collected from a sample of 334 medical students in China. The participants were 18 to 24 years old (47% female) and 18.4% of them smoked in the past 30 days. Multivariate analysis indicated that cigarette smoking was negatively associated with nine Terminal Values (e.g., a Sense of Accomplishment and Self-Respect) and ten Instrumental Values (e.g., Clean and Self-Controlled). As expected, when the endorsed number of values/total value scores increased from low to high, the 30-day smoking rate declined from 32.6% - 75.0% to 13.5% - 15.9% (p < .01). The odds ratios (OR) for the endorsed Terminal Values and the total value scores were 0.50 (p < .01) and 0.64 (p < .01) respectively, and the ORs for the endorsed Instrumental Values and the total value scores were 0.42 (p < .01) and 0.44 (

Nonzero Sum Differential Game of Mean-Field BSDEs with Jumps under Partial Information

This paper is concerned with a kind of nonzero sum differential game of mean-field backward stochastic differential equations with jump (MF-BSDEJ), in which the coefficient contains not only the state process but also its marginal distribution. Moreover, the cost functional is also of mean-field type. It is required that the control is adapted to a subfiltration of the filtration generated by the underlying Brownian motion and Poisson random measure. We establish a necessary condition in the form of maximum principle with Pontryagin’s type for open-loop Nash equilibrium point of this type of partial information game and then give a verification theorem which is a sufficient condition for Nash equilibrium point. The theoretical results are applied to study a partial information linear-quadratic (LQ) game
