The Intelligence Structures of School-Age Children with Attention Deficit Hyperactivity Disorder: A Multicenter Cross-Sectional Study in China.

Purpose: There is no consensus on whether cognitive measures among attention deficit hyperactivity disorder (ADHD) subtypes exhibit more similarities or differences, and most of them have been conducted on English-speaking subjects, lacking cross-cultural perspectives. The present study was aimed at investigating the intelligence structures of school-age children with ADHD who speak Chinese, using a multicenter and large sample size approach, offering some references for clinicians.

Patients And Methods: 772 children aged 6 to 12 years with ADHD took part in the cross-sectional study.

Ferro-Valleytricity with In-Plane Spin Magnetization.

Ferro-valleytricity that manifests spin-orbit coupling (SOC)-induced spontaneous valley polarization is generally considered to occur in two-dimensional (2D) materials with out-of-plane spin magnetization. Here, we propose a mechanism to realize SOC-induced valley polarization and ferro-valleytricity in 2D materials with in-plane spin magnetization, wherein the physics correlates to non-collinear magnetism in triangular lattice. Our model analysis provides comprehensive ingredients that allow for ferro-valleytricity with in-plane spin magnetization, revealing that mirror symmetry favors remarkable valley polarization and time-reversal-mirror joint symmetry should be excluded.

Improving Nitric Oxide Reduction Reaction Activity of TMN-C Model Catalysts by Axial Atom Coordination.

In comparison with the conventional four-nitrogen coordinated transition metal (TMN), we clarify that the electrochemical nitric oxide reduction reaction (NORR) activity can be significantly improved by axially coordinating nonmetal atoms (O, F, Cl) over the metal sites. In light of an electron-withdrawing effect, the axial fifth ligand disrupts the electron distribution symmetry and regulates the local electronic structure of the metal active center. It subsequently moderates the TM-NO interaction and thus enhances the activity.

The 3D-CN serves as the photoanode, offering stable photocurrent production due to its three-dimensional open framework structure.

In particular, the spin-singlet spatially indirect excitons in BiSTe monolayer are dipole/parity allowed and reveal befitting characteristics for excitonic condensation, such as small effective mass and satisfied dilute limitation.
