Publication date: Available online 22 October 2019Source: Sensors and Actuators A: PhysicalAuthor(s): Dong Sun, Yu-juan Tang, Jiong Wang, Xin-jie WangAbstractIn this contribution, an H-shaped piezoelectric motor based safety and arming device that is driven by the hybrid of symmetrical first longitudinal mode and second bending mode is proposed, designed and experimental investigated. The proposed system operates based on the concept of self-moving and show potential infield of fuse system with different calibers. The actuating mechanism is that the four driving feet contact with the guides alternately and push the motor t...

Publication date: December 2019Source: Results in Physics, Volume 15Author(s): Yuanhang Weng, Hong Wang, Peijun Chen, Geyu TangAbstractWe propose the (2 + 1) dimensional all-optical logical gates based on the interaction between two components of vector solitons in nonlocal nonlinear media. The input logical states are controlled by tilting the input beams or not, and the output logical states are decided by integrated power on the photodetector. We design these logical gates in a theoretical model of liquid crystal E7 with only two input beams that are tilted in 2 dimensions, and this model is suitable to other nonloc...

We present a unified method to derive the reflectivity of a plane wave normally incident on an interface. The key idea is to use the flux continuity and the proposed principle of least reflection to acquire the needed generality and conciseness. The result provides a special understanding on the origin of reflection and the half-wave loss.

Publication date: December 2019Source: Results in Physics, Volume 15Author(s): Tao Siwei, Yue Huimin, Chen Hongli, Wang Tianhe, Cai Jiawei, Wu Yuxiang, Liu yongAbstractIn phase measuring deflectometry (PMD), the existence of parasitic reflections at the rear surface of transparent objects will lead to ‘ghosted’ fringe patterns, which results in phase error. Accurately extracting the phase from the 'ghosted' fringe patterns is considered as one of the main problems in PMD. Existing phase extraction methods still remain some drawbacks such as high cost of experiment equipment, the existence of ill-conditioned are...

Publication date: December 2019Source: Results in Physics, Volume 15Author(s): T. Sakhraoui, M. SaidAbstractBased on the framework of a generalized gradient approximation (GGA) to density functional theory (DFT), the structural, electronic and magnetic properties of the Fe8−xMnxRh8 compound have been studied. Results show that by adding Mn into FeRh system the optimized lattice parameter slightly changes and it follows the Vegard’s law. It’s also found that the electronic states near the Fermi level are mainly contributed by the Rh states. They are characterized by a decrease or an increase of the occupat...

Publication date: December 2019Source: Results in Physics, Volume 15Author(s): Xuanmin Zhu, Haiyan Yan, Xinming Wang, Meiguang Zhang, Qun WeiAbstractCarbon is known to form a number of allotropes due to its ability to exist in different hybridizations. Here, based on first-principles calculations combined with crystal structure searching method, a new hexagonal carbon allotrope named h-C63 was proposed. The calculated elastic constants and phonon calculations confirm that h-C63 is dynamically and mechanically stable. We show that h-C63 is a potential superhard material with the hardness of 58.8 GPa, and electronic struct...

Publication date: January 2020Source: Radiation Physics and Chemistry, Volume 166Author(s): E. Kavaz, S.R. Armoosh, U. Perişanoğlu, N. Ahmadi, M. OltuluAbstractThis work focused to survey the radiation shielding properties of cement paste samples doped without and with Cu 10% and brass 5, 10, 15, 20% wt. Molar volume of the cement samples was determined by the densities obtained with the Archimedes principle. Transmission measurements of the samples were achieved using an Ultra Ge detector at 81, 276, 302, 356, 383 keV photon energies emitted from the Ba-133 radioactive point source. The essential parameters; mass atte...

Publication date: Available online 22 October 2019Source: Physics of Life ReviewsAuthor(s): Luiz PessoaAbstractWhat is the place of emotion in intelligent robots? In the past two decades, researchers have advocated for the inclusion of some emotion-related components in the general information processing architecture of autonomous agents, say, for better communication with humans, or to instill a sense of urgency to action. The framework advanced here goes beyond these approaches and proposes that emotion and motivation need to be integrated with all aspects of the architecture. Thus, cognitive-emotional integration is a k...

Publication date: Available online 22 October 2019Source: Physics Letters AAuthor(s): Yoshihiro Shimazu, Tatsuya Iwabuchi, Kensuke Arai, Inoru ShioyaAbstractHall effect measurements conventionally rely on the use of dc magnetic fields. For electronic devices made of ultrathin semiconducting materials, such as molybdenum disulfide (MoS2), the dc Hall effect measurements have practical difficulties. Here, we report the results of the Hall effect measurements using ac magnetic fields and a lock-in detection of the Hall voltage for field effect transistors with ultrathin MoS2 channels. The ac Hall effect measurements have some...
