Summary: This paper uses a finite element mathematical model to study electroporation and electrofusion, and improves the mathematical models by analyzing the distribution, radius, and density of pores. The results show that nanosecond pulses can avoid the effect of cell size on electrofusion and have larger pore radius at the contact point between cells.

Summary: Bimetallic chalcogenides, particularly Ag8SnS6 nanoparticles, have shown promising catalytic activity for the hydrogen evolution reaction (HER). Adjusting the precursor molar ratio and coupling with carbon nanotubes (CNTs) can significantly enhance the catalytic performance of Ag8SnS6 nanoparticles, making them efficient and stable HER electrocatalysts in acidic solutions. This study provides valuable insights for the optimization of bimetallic chalcogenides as HER electrocatalysts.

Summary: The thermal evolution pathways of asteroids were studied using the finite element method (FEM) and compared with another algorithm, the finite difference method (FDM). The FEM and FDM showed slight differences in temperature calculation, particularly in the center of the model. The study of the S-type asteroid Astraea revealed a high temperature area in its interior with a similar shape.

Summary: This study developed a mathematical model to investigate the evolution of pores during cell electroporation. The simulation results showed a sigmoid increase in pore area ratio (PAR) over time, indicating a cumulative effect of PAR. Additionally, the relationship between high-frequency irreversible electroporation (H-FIRE) parameters and the cumulative effect of PAR was established, allowing for effective design of cell ablation protocols.

Summary: A study found that coating metal electrodes with an organic polymer PEDOT:PSS can prevent intracellular ROS generation and reduce cell electroporation and intracellular calcium response caused by PEF application. These coated electrodes can be used for PEF application in ROS-sensitive tissues and differentiate the effects of PEFs on cells from the metabolic impact of electrolytic events.

Summary: This study investigated the effect of low-field pulsed electric fields (PEF) on broccoli stalks. The results showed that low-field PEF induced membrane disintegration in broccoli stalks. The specific energy input had a more prominent effect on the volatile profile of broccoli stalks compared to the field strength. Therefore, specific energy input plays a significant role in controlling the volatile profile of broccoli stalks.

Summary: This study focuses on the local variations of the electric field and current density around bubbles formed by water electrolysis using PEF technology, and how these variations affect the electroporation protocol. It is found that the edge effect around the bubbles can significantly increase the electric field and current density, leading to unwanted limitations on PEF treatment.

Summary: This study aimed to investigate the mechanism of bacterial cell inactivation by pulsed electric fields (PEF) through studying the release of intracellular components of Staphylococcus aureus cells. The results showed that the release of certain components, such as ions, correlated with membrane permeabilization, while the inactivation of S. aureus by PEF was related to the release of cytoplasmic proteins above a certain molecular weight. Additionally, increasing PEF treatment time was found to reduce the cell's ability to repair electropores, potentially due to the formation of larger pores.

Summary: The pulsed electric field technique (PEF) was used as the principal technique for the process development of quick-cooking rice products. The study evaluated the effect of pulse number, electric field strength, and frequency on cooking time and full grain portion. The optimal condition significantly reduced the cooking time of rice by 40-50% and improved the textural properties. PEF treatment also enhanced the in vitro digestibility of protein and starch.

Summary: This paper proposed a nonlinear dispersive multiphysics model of single-cell electroporation, investigating the effects of dispersion and dynamic pore radius on the redistribution of the electric field. It was found that the dispersive membrane increases transmembrane potential and expedites the electroporation process, while the dynamic pore radius function has the opposite effect on transmembrane potential and membrane permeability.

Summary: The research shows that the coupled radiation and temperature effect has a minor impact on the gain of Erbium-doped fiber amplifier (EDFA) and Erbium-ytterbium-doped fiber amplifier (EYDFA). Furthermore, the study also found that radiation-induced attenuation (RIA) kinetics of rare-earth-doped fibers can be influenced by the presence of codopant cerium.

Summary: This study investigates the gain degradations of an Er-doped fiber amplifier exposed to X-rays at different temperatures, highlighting the combined effect of temperature and radiation on the RIA levels and kinetics. Experimental results show a slight impact on the EDFA gain degradation kinetics when varying the irradiation temperature, while the comparison between modeled and measured gain degradation kinetics at higher doses suggests the need for a more precise modeling of temperature impact for future space missions.

Summary: We investigated the impact of X-ray radiation on the performance of backup EDFAs and EYDFA. The study found that the type of active optical fiber used in the amplifiers affects the pumping conditions and photobleaching efficiency. Notably, the backup EDFA designed with radiation-hardened fiber does not experience extra degradation in the OFF mode, while the one designed with nonrad-hard fiber can reduce degradation by briefly powering the amplifier. Similarly, the tested radiation-tolerant EYDFA showed enhanced vulnerability in the OFF mode, but can also be mitigated with brief powering.

Summary: This paper provides a detailed overview of recent progress in sinuous antennas, focusing on antenna geometry, dielectric structure, and miniaturization techniques. The basic principles of frequency-independent antennas, such as self-complementary and log-periodic geometries, are introduced, along with antenna geometries characterized in terms of angles. The paper illustrates the operating principles, advantages, design considerations, limits, and challenges of conventional sinuous antennas. Technical solutions to optimize the trade-off between antenna size and radiation behavior, such as modifications to the antenna geometry and the use of dielectric structures, are presented. Additionally, a new class of supershaped sinuous antenna is introduced, which combines the 2D superformula and the sinuous curve to improve performance in terms of directivity, beam stability, beam angle, gain, and radiating efficiency.

Summary: This paper illustrates an improved quantum-behaved particle swarm optimization (QPSO) approach for modeling antenna impedance. The introduced enhanced weighted quantum particles swarm optimization (EWQPSO) achieves local convergence on a reduced number of free parameters. Several tests were conducted to verify the performance of the proposed EWQPSO, showing that it achieves faster convergence compared to other QPSO-based optimization algorithms. A lumped element equivalent circuit was designed and the developed EWQPSO algorithm successfully recovered all the parameters characterizing the circuit, resulting in good impedance fidelity over the whole frequency range.

Summary: The use of fractional derivatives and integrals in electromagnetic theory has shown promising results in capturing effects and generalizing Maxwell's equations. In this paper, the authors provide a brief review of fractional vector calculus and its applications, focusing on dielectric relaxation processes exhibiting non-exponential decay. A homemade fractional calculus-based FDTD scheme is discussed in detail, with considerations for computational domain bounding and numerical stability. Examples involving dispersive dielectrics demonstrate the usefulness and reliability of the developed FDTD scheme.
