Non‐vanishing of Poincaré series on average
Mathematika, Volume 72, Issue 2, April 2026.Abstract We study when Poincaré series for congruence subgroups do not vanish identically. We show that almost all Poincaré series with suitable parameters do not vanish when either the weight k$k$ or the index m$m$ varies in a dyadic interval. Crucially, analyzing the problem ‘on average’ over these weights or indices allows us to prove non‐vanishing ...

Advanced Science, Volume 13, Issue 13, 3 March 2026.The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Advanced Science, Volume 13, Issue 14, 9 March 2026.An anisotropic dual S‐scheme heterojunction (C3N4/SubPc‐1/C3N5) is constructed to overcome the electron–proton kinetics mismatch in photocatalytic H2O2 production. The imide bridge serves as a dual channel for ultrafast electron transfer and proton relay, synergistically enabling efficient dual‐pathway oxygen reduction and achieving a high H2O2 ...

Vacancy‐Controlled Lattice Dynamics and Magnetism in Mn‐Doped CeO2−δ Nanocrystals
Annalen der Physik, Volume 538, Issue 3, March 2026.ABSTRACT Mn‐doped CeO2−δ${\rm CeO}_{2-\delta }$ nanocrystals provide a model system to quantify how defect chemistry controls emergent magnetism in a wide‐gap oxide. Single‐phase fluorite Ce1−xMnxO2−δ${\rm Ce}_{1-x}{\rm Mn}_x{\rm O}_{2-\delta }$ (0≤x≤0.09$0 \le x \le 0.09$) nanocrystals exhibit nonmonotonic changes in lattice parameter, microstrain ...

Equivariant toric geometry and Euler–Maclaurin formulae
Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Ghost effect from Boltzmann theory
Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 558-675, March 2026.Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Food and Energy Security, Volume 15, Issue 2, March/April 2026.ABSTRACT Net photosynthetic rate (Pn) serves as a key indicator for evaluating plant growth and yield. In order to explore an effective method for monitoring winter rapeseed Pn using unmanned aerial vehicle (UAV) multispectral technology, the winter rapeseed was taken as the research object and the multispectral images were obtained through UAVs in ...
