Summary: In this paper, the Kinematical vortical effect (KVE) transport coefficients are studied using the Zubarev quantum-statistical density operator for the Rarita-Schwinger-Adler theory. The relationship with the gravitational anomaly is demonstrated and a prediction is made about the possible form of the transport coefficients for massless fields with arbitrary spin.

Summary: In this study, the breakup of water droplets in water-in-oil emulsions under high-voltage and high-frequency pulsed electric fields was investigated using a comprehensive approach of microscopic experiment, theoretical derivation, and molecular dynamics simulation. The research findings revealed three main modes of droplet breakup and derived critical field strengths to predict breakup locations. The formation and migration of hydrated ions played a crucial role in droplet breakup, and the energy of the electric field transformed into the deflection of dipole moment and velocity of water molecules.

Summary: Chiral Co3O4 supraparticles (SPs) were fabricated with a significant g-factor and paramagnetic performance for treating thromboembolism under an electromagnetic field. In vitro experiments showed that d-SPs had stronger thrombolytic ability compared to l-SPs, leading to an enhanced survival rate in thrombosis model mice. Mechanism study revealed that d-SPs produced higher levels of reactive oxygen species (ROS) under MF due to chiral-induced spin selectivity effects.

Summary: The shift from fossil fuels to renewable energy sources in the power system has led to the search for new reserve providers to ensure flexibility. Smart charging for electric vehicles has emerged as a promising solution, but there are uncertainties regarding reserve activation and EV availability. This study introduces a new method for modeling reserve activation uncertainty in European markets and demonstrates the improvement of proposed stochastic and robust models compared to deterministic approaches.

Summary: This article discusses the possible ways to generate neutrino mass and dark matter through the scotogenic mechanism in a dark U(1)(D) symmetric hidden sector. The charge assignment of hidden fermions is considered chiral and anomaly-free, and the minimal scotogenic models for Majorana neutrinos and Dirac neutrinos are identified. The dark matter is found to be multicomponent and always contains Dirac fermionic species.

Summary: It is demonstrated for the first time that the catalytic properties of semiconductors can be activated by an external electric field. Specifically, TiO2 and Fe2O3 are able to produce noticeable amounts of carbon monoxide from a carbon dioxide-water vapor mixture under the influence of an electric field with a strength in the range of 10(4) V/cm. This process, known as the activation of semiconductors using an electric field, is more efficient than utilizing UV-vis radiation in terms of energy efficiency and the amount of products formed.

Summary: Two-dimensional organic-inorganic hybrid perovskites have been intensively explored due to their tunable band gaps, exciton binding energies, and increased stability. Experimental observations suggest localized edge states in 2D hybrid perovskites, with multiple proposed origins. First-principles calculations show that layer edge states are stabilized by internal electric fields in 2D hybrid perovskites, facilitating their design for optoelectronic applications.

Summary: This study investigated the lubrication performances of polyalkylene glycols, which are insulating oils, under external electric fields. The results showed that these electric fields significantly influenced the lubrication performances and there was an optimal voltage for friction reduction improvement. Surface analysis and experimental results indicated that the formation of adsorption film and the reduction of certain substances contributed to improved friction performance under negative voltage conditions. This work demonstrated the impact of external electric fields on the lubrication performances of insulating oils and proposed a lubrication model for understanding the lubrication mechanisms in electric environments.

Summary: We investigate the Floquet dynamics of a particle in a three-well system driven by a two-frequency field. We identify integer and fractional photon resonances due to the dual-frequency driving. Pairs of photon-assisted tunneling near the resonance are found to originate from avoided level crossings in the Floquet spectra, which are quantum features of hybridization between different quantum states. This study establishes a close connection between fractional-order resonances and the properties of Floquet modes under two-frequency driving conditions, and illustrates their dependence on driving parameters. These results provide a possibility for coherent control of quantum states using classical external driving fields.

Summary: In this study, multiple sulfur corrosion was simulated on the oil-paper insulation system to investigate the mechanical properties and hydrogen bond of the insulating paper, as well as the mean square displacement (MSD) and shear viscosity of the insulating oil under different electric and thermal fields. The electric field had a significant impact on the degradation of the elastic modulus of cellulose, with the dc electric field showing a more obvious influence than the ac electric field. Temperature also played a significant role in the modulus parameters, with a considerable decrease in the elastic modulus as temperature increased. The study's findings provide valuable insights into the microscopic mechanism of multiple corrosive sulfides and effective protection techniques against sulfur corrosion.

Summary: This study investigates the effects of different electric fields on methane hydrates using molecular dynamics simulations. The results indicate that a terahertz bidirectional pulsed electric field (BPEF) achieves the highest efficiency in hydrate decomposition by inducing a structural phase transition from crystalline to liquid. In addition, the amplitude of BPEF shows a positive correlation with decomposition efficiency, and frequencies close to 1.8, 7.0, and 18.5 THz exhibit superior efficiency.

Summary: Calorimetry for equilibrium systems aims to determine the energy levels' occupation and distribution by measuring thermal response, while nonequilibrium versions provide additional information on the dynamical accessibility of these states. Using calculations on a driven exclusion process, it is confirmed that a fermionic nonequilibrium steady state with exact computation of specific heat can be achieved. The divergence at zero temperature occurs when the Fermi energy and the kinetic barrier for loading and emptying are approximately equal. Additionally, a stable low temperature regime of negative specific heat appears when the kinetic barrier is density-dependent, indicating an anti-correlation between the stationary occupation's temperature-dependence and excess heat.

Summary: We obtained the metric of the Hayward black hole surrounded by a cloud of strings, and analyzed the effects of the string cloud on the regularity of the solution and the energy conditions. Various aspects such as horizons, geodesics, effective potential, and thermodynamics were investigated. We compared the obtained results with the literature corresponding to the Hayward black hole without a string cloud.
