Summary: The study found that perceiving automated vehicles as lacking agency may lead to greater anger towards their aberrant behaviors. Attributing high agency to AVs eliminated the difference between humans and AVs. Perceiving AVs as having high capability to feel and sense might induce more negative reactions.

Summary: This study examined the interactions between automated and conventional vehicles on mixed traffic roads in the future. Results showed that the attributions of intentionality, emotional reactions, and intended behaviors were complex. Despite lower attributions of intentionality, intended responses were more severe in self-driving car conditions. Describing self-driving cars as having a heart and mind led to similar behavioral responses but different affective ratings.

Summary: This study investigates microscopic engines that utilize a single active particle as the working medium, demonstrating the recovery of energy for work during the directed motion of the particle at constant temperature. By considering the chemical degrees of freedom, a wide range of synthetic active particles can be studied without the need to determine the exact microscopic mechanism. Analytical results reveal that the quasistatic thermodynamic efficiency increases beyond the linear-response regime and reaches a maximum at high propulsion speeds, indicating the nontrivial consequences of driving in the active engine's efficiency.

Summary: This paper proposes an electric propulsion system model for computationally efficient multiobjective optimization considering overall driving cycles using coupled electromagnetic-thermal 1D simulation. The proposed system model uses equivalent circuit networks to achieve high computational efficiency. The study examines the magnetic saturation effect and temperature change of the traction motor, and integrates the lumped parameter thermal network to consider the motor temperature change without any iterative process. The 1D simulation results show that the changes in induced current, efficiency, and motor temperature can be predicted while driving. The multiobjective optimization successfully obtains the optimal design for multiple target driving cycles.

Summary: The study investigates the dynamics of chemically powered sphere dimers at the micro- and nano-scales in a quasi-two-dimensional geometry. It is found that the asymmetric concentration gradients generated by a chemical reaction on the catalytic surface lead to self-propulsion of the dimers, forming anti-parallel aligned doublets that exhibit the same rotation direction and lose translational motion. The chirality of the dimers plays a crucial role in the formation of these doublets, displaying new collective dynamics and structures when both translational and rotational self-propulsion occur simultaneously.

Summary: Connected automated vehicles (CAVs) use sensors to scan their surrounding environment in order to make safe and efficient motion decisions. High-end sensors provide quality data, allowing CAVs to rely on their own sensors through individual sensing, and to become independent of other vehicles. This study investigates the trade-offs in the values and costs of individual versus cooperative sensing, and proposes optimal investment strategies for short- and long-term planning.

Summary: Spatial nonuniformity significantly affects the motion of Faraday wave patterns, as evidenced by the zigzag and drift dynamics of their wave crests. A minimal theoretical model successfully characterizes the growth of localized patterns under nonuniform parametric driving. Numerical solutions of the governing equations match experimental findings and theoretical predictions. These results advance the understanding of pattern behavior induced by nonuniformity in generic nonlinear extended systems far from equilibrium.

Summary: Pumps and motors are crucial components in our world, and the advent of artificial molecular machines has provided scientists with unprecedented control over molecular motion through kinetically controlled, away-from-thermodynamic equilibrium chemistry. By designing molecules with kinetic asymmetry, potential landscapes can be engineered to harness external energy for the formation and maintenance of geometric structures of molecular components away from equilibrium.

Summary: Single enzyme chemotaxis refers to the creation and maintenance of an enzyme's nonequilibrium spatial distribution through concentration gradients of the substrate and product. This phenomenon can occur naturally or experimentally. This paper proposes a mechanism based on diffusion and chemical reaction, demonstrating that kinetic and diffusion asymmetries determine the direction of chemotaxis. The results suggest that systems evolve to attain greater kinetic stability and accumulate in regions with smaller effective diffusion coefficients. Additionally, the presence of nonreciprocal attraction and repulsion between enzymes in a catalytic cascade is important in active matter behavior.
