Background Gender bias is a type of discrimination based on gender, which can lead to increased self-doubt and decreased self-esteem. Sexual harassment is a hostile form of gender bias that can cause anxiety, depression, and significant mental health issues. Virtual reality (VR) has been employed to help make people become aware of their biases and change their attitudes regarding gender, race, and age. Methods Forty participants were embodied in avatars of different genders and experienced sexual harassment scenarios in VR. A gender Implicit Association Test (IAT) was administered before and after the experience. Results There was a statistically significant main effect of participant gender ( F (1,36) = 10.67, p = .002, partial η2 = .23) on ΔIAT, where males and females reported a decrease (M = −.12, SD = .24) and an increase (M = .10, SD = .25) in IAT scores, respectively. A statist...

First, a mathematical model was constructed to illustrate the relationship of wind direction, aircraft attitude and disturbance force. Next, a new attitude extraction algorithm using wind direction was designed based on the traditional backstepping control method. And the control input was limited by saturated function method to solve the problem of thrust boundedness. Finally, a position controller for tailsitter aircraft was designed with simulation showing its effectiveness.

Various threats such as network attacks, malicious code and vulnerability utilization are gradually increasing. Consequently, it is urgent to study industrial threat detection methods. In order to tackle typical network attacks, system vulnerabilities and malicious operations, a real-time intelligent industrial threat detection method is proposed by analyzing the network data in the industrial control system. Particularly, artificial intelligence technique, adversarial sample generation technique and deep learning model are used in the method. Besides, the proposed method is achieved in the real network, and the corresponding industrial threat detection platform is developed. The results show that the developed threat detection platform can detect a variety of typical network attacks, system vulnerabilities, malicious code, etc. At the same time, the platform has good throughput and compatibility and is suitable for the actual industrial environment.

MATERIALS AND METHODS Experimental cement was formulated by adding 7.5% silver-nanoparticle-containing amorphous calcium phosphate microparticles to Multilink Automix resin cement (Ivoclar Vivadent). The experimental cement was evaluated for shear bond strength (N=11 per group) and demineralization/remineralization (N=16 per group), with BioCem® Universal BioActive cement (NuSmile) as the positive control and Multilink Automix cement as the negative control. One-way analysis of variance and post hoc tests were used to assess the significance of differences among or between the groups RESULTS: : The addition of silver-nanoparticle-containing amorphous calcium phosphate microparticles at the level of 7.5% by weight into Multilink Automix did not have a statistically significant effect on the shear bond strength (p>0.05), but statistically significantly increased the depth of remineralization on both dentin and enamel (p=0.01 and p<0.001, respectively.) when compared to Multilink Automix alone. The experimental cement prepared in the present study was comparable to BioCem® on the depths of remineralization on both dentin and enamel (p=0.59 and p=0.99, respectively). CONCLUSION When incorporated into non-bioactive commercial dental resin cements as bioactive fillers at the level of 7.5% by weight, silver-nanoparticle-containing amorphous calcium phosphate microparticles could provide remineralization potential without affecting the shear bond strength.

However, the collagen membranes currently used in clinics lack an active antibacterial function, although infection at surgical sites presents a realistic challenge for guided tissue/bone regeneration. In this study, we successfully prepared novel and advanced collagen composite membranes from collagen and complexes of heparin and chelates of minocycline and Ca2+ ions. These membranes were characterized for chemical structures, morphology, elemental compositions and tensile strength. In vitro release studies were conducted to evaluate the release kinetics of minocycline from these membranes. Agar disk diffusion assays were used to assess their sustained antibacterial capability against model pathogenic bacteria Staphylococcus aureus. The chemical and physical characterization confirmed the successful synthesis of minocycline-loaded collagen composite membranes, namely NCCM-1 and NCCM-2. Both membranes had weaker tensile strength as compared with commercial collagen membranes. They achieved sustained release of minocycline for at least 4 weeks in simulated body fluid (pH 7.4) at 37°C. Moreover, both membranes demonstrated potent sustained antibacterial effects against Staphylococcus aureus. These results suggested that the advanced collagen composite membranes containing minocycline can be exploited as novel guided tissue regeneration membranes or wound dressing by providing additional antibacterial functions.

Accurate characterization of the nitrogen concentration and distribution in ultra thin nitrided s... more Accurate characterization of the nitrogen concentration and distribution in ultra thin nitrided silicon gate oxide plays the same important role as the fabrication technology itself during the development of 90nm and beyond gate oxide manufacturing process. Based on the measurement results of XPS (X-ray photoelectron spectroscopy) as reference, a correlation study was taken between XPS and AES (Auger electron spectroscopy) data in this paper. The study shows that, by optimizing the experiment conditions of AES such as beam energy, beam current and take off angle, and introducing proper corrective factor, AES can be used as a useful and reliable characterization tool during the monitoring measurement of Nitrogen concentration in ultra thin (<2nm) nitrided silicon gate oxide.
