Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Molecules as metric measure spaces with Kato-bounded Ricci curvature
Set $\Psi :=\log (\tilde{\Psi })$, with $\tilde{\Psi }>0$ the ground state of an arbitrary molecule with $n$ electrons in the infinite mass limit (neglecting spin/statistics).

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

Abnormally high Patient State Index associated with epicardial pacing: a case report
Background Anesthesiologists monitor electroencephalography (EEG) intraoperatively to maintain adequate depth of anesthesia. However, the EEG signal is affected by noise and interference.

A submultiplicative property of the psi function
The main result offered by the authors is that \(\Gamma'(xy+t)\Gamma(x+t)\Gamma(y+t) \leq \Gamma(xy+t)\Gamma'(x+t)\Gamma'(y+t)\) for all nonnegative \(x\) and \(y\) iff \(t\geq a\) where \(\Gamma\) is Euler's gamma function and \(a\) is the only positive number with \(\Gamma'(a)=\Gamma(a).\) They offer also a similar result with subadditivity in place ...

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Near-threshold photoproduction of $$J/\psi $$ J / ψ in two-gluon exchange model
The near-threshold photoproduction of $$J/\psi $$ J / ψ is regarded as one golden process to unveil the nucleon mass structure, pentaquark state involving the charm quarks, and the poorly constrained gluon distribution of the nucleon at large x ( $$>0.1$$

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...
