Coulomb and Franklin’s electricity laws are used in this paper to model an efficient optimization algorithm based on electric particle searches, which has been named CFA. For the CFA optimizer, the influence of electrically charged particles on each other in charged things has been predicated on the forces of attraction and repulsion. Evolutionary algorithms (EA) such as hybrid real coded genetic algorithm (RCGA) which combines the global and local search (GL-25), differential evolution (DE) with strategy adaptation (SaDE), composite DE (CoDE), the improved standard particle swarm optimization 2011 (SPSO2013) and the grouped comprehensive learning PSO (GCLPSO) are compared to the CFA optimizer for finding global solutions of seven basic benchmark functions of high dimension D = 50. (GCLPSO). Experiments have shown that the suggested CFA optimizer is quite effective and competitive for the benchmark functions. Note that the source code of the CFA algorithm is publicly available at https://***/projects/cfa, https://***/matlabcentral/fileexchange/127727-franklin-s-laws-inspired-algorithm-cfa. © 2023, ICST Institute for Computer sciences, Social Informatics and Telecommunications Engineering.

This paper presents a study comparing GaAs solar cells with different structures grown by metal-organic vapor phase epitaxy (MOVPE). The impacts of absorber type and junction position are individually analyzed regarding the solar cell performance. When using the same structures, the n-type absorber samples had enhanced open-circuit voltage (Voc) and radiative efficiency than the p-type absorber ones, indicating superior crystal quality of n-GaAs. Besides, when using the same type of absorber, front-junction (FJ) samples showed an all-around boosted performance than rear-junction (RJ) ones, refreshing our understanding of the role of RHJ structure. Based on these observations, a p-on-n FJ structure using an n-GaAs absorber is recommended for high-performance solar cells.

The present study proposes a coupled chemo-transport-mechanical damage model for the mineral transformation in cementitious materials under a sulfate-rich environment. The proposed coupled chemo-transport-mechanical damage model integrating thermodynamics, fluid-solid transformation, and mechanical damage modeling is used to predict the physicochemical characteristics of cementitious materials under a sulfate-rich environment. For verifying the proposed model, calcium sulfoaluminate (CSA) cements with various m-values were adopted for a case study. The thermodynamics model for the phase assemblage of CSA cements with various m-values under a sulfate-rich environment is compared with the experimental outcomes. The model parameters in the fluid-solid transformation and mechanical damage models are fitted through the available experimental data in the literature. Mineral compositions, crystallization pressure, effective elastic modulus, delayed ettringite formation, and microcracks of CSA cement paste were modeled by a proposed coupled chemo-transport-mechanical damage modeling, with model parameters fitted to experimental data, thereby assessing the applicability of the proposed model. © 2023, The Authors.

Terahertz (THz) has broad applications for imaging, spectroscopy, and high-data-rate communication. However, THz detection at room temperature remains a significant challenge. By model Hamiltonian including electron-phonon coupling and photon-electron interaction within dipole approximation, we demonstrate that atomic displacement A⃗(t) driven by THz field E⃗(t) can induce static nonlinear electronic polarization in semiconductors without spatial inversion symmetry by nonlinear optic effect (αijkEjEk), Raman effect (βijkAjEk), and nonlinear phononic effect (γijkAjAk). Our numerical calculations also reveals that nonlinear phononic effect dominates the change of static polarization in ferroelectric semiconductor BaTiO3 irradiated by THz field. This work presents a design principle for efficient THz detection at room temperature by monitoring the change of surface polarization induced by THz-driven lattice vibration.

Ultrafast removal of toxic Cr(VI) by the marine bacterium Vibrio natriegens

The fastest-growing microbe Vibrio natriegens is an excellent platform for bioproduction processes. Until now, this marine bacterium has not been examined for bioremediation applications, where the production of substantial amounts of biomass would be beneficial. V. natriegens can perform extracellular electron transfer (EET) to Fe(III) via a single porin-cytochrome circuit conserved in Vibrionaceae. Electroactive microbes capable of EET to Fe(III) usually also reduce toxic metals such as carcinogenic Cr(VI), which is converted to Cr(III), thus decreasing its toxicity and mobility. Here, the performance of V. natriegens was explored for the bioremediation of Cr(VI). At a density of 100 mg/mL, V. natriegens removed 5–20 mg/L Cr(VI) within 30 s and 100 mg/L Cr(VI) within 10 min. In comparison, the model bacterium Escherichia coli grown to a comparable cell density removed Cr(VI) 36 times slower. To eliminate Cr(VI), V. natriegens had to be metabolically active, and functional outer-membrane c-type cytochromes were required. At the end of the Cr(VI) removal process, V. natriegens had reduced all of it into Cr(III) while adsorbing more than half of the metallic ions. These results demonstrate that V. natriegens, with its fast metabolism, is a viable option for the rapid treatment of aqueous pollution with Cr. © 2024 Elsevier Ltd

Actuator-Constrained Reinforcement Learning for High-Speed Quadrupedal Locomotion

This paper presents a method for achieving high-speed running of a quadruped robot by considering the actuator torque-speed operating region in reinforcement learning. The physical properties and constraints of the actuator are included in the training process to reduce state transitions that are infeasible in the real world due to motor torque-speed limitations. The gait reward is designed to distribute motor torque evenly across all legs, contributing to more balanced power usage and mitigating performance bottlenecks due to single-motor saturation. Additionally, we designed a lightweight foot to enhance the robot’s agility. We observed that applying the motor operating region as a constraint helps the policy network avoid infeasible areas during sampling. With the trained policy, KAIST Hound, a 45 kg quadruped robot, can run up to 6.5 m/s, which is the fastest speed among electric motor-based quadruped robots. Copyright © 2023, The Authors.
