Clusters composed of heavy elements, particularly actinides, provide a compelling platform for exploring unconventional bonding and the role of relativistic effects in electronic structure and stability. In this study, we critically reassess the -symmetric PaB cluster, previously claimed to exhibit double Möbius-Craig aromaticity through delocalization of 4σ and 4π electrons. Our potential energy surface (PES) analysis disproves this assignment by showing that the structure is a higher-energy isomer; the most stable form adopts a distorted tetrahedral structure.

This paper explores the ethical implications of long-term, transgenerational projects through the lens of neo-republican theory, focusing on the issue of intergenerational domination. Traditional accounts of intergenerational justice often emphasize one-directional influence from present to future generations. This study proposes a threefold generational framework-the current generation (CG), subsequent generations (SGs), and remote generations (RGs)-to better capture the temporal complexity and multi-layered dependencies that define transgenerational projects such as radioactive waste management.

The discovery of unusual magnetoresistance (UMR) during the rotation of magnetization in the plane perpendicular to the electric current, which has been typically attributed to the magnetization-dependent interfacial reflection of the spin current, has had a remarkable impact on the understanding and application of a variety of spintronics phenomena. Here, we report that giant UMR occurs also in single-layer magnetic metals and exhibits high-order contributions and a universal sum rule, which agree well with the physics origin of the recently proposed two-vector magnetoresistance that simply considers electron scattering by the magnetization vector and interfacial electric field, without the need for any relevance to the spin/orbital current or crystalline symmetry. Revisiting of the literature data reveals that the most representative data that were used to claim spin Hall magnetoresistance or other magnetoresistances related or unrelated to spin current can be understood unifiedly by using the two-vector MR theory.

Gaze is one of the primary experimental measures for studying cognitive development, especially in preverbal infants. However, the field is only beginning to develop a principled explanatory framework for making sense of the various factors affecting gaze. We approach this issue by addressing infant gaze from first principles, using rational information gathering.
