Completely and logarithmically completely monotone functions

We give simpler proof of known theorems, extend the validity of them, generalize them, correct some erroneous results, and prove some new results.

Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

Advanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.

Advances in Halide Perovskites for Photon Radiation Detectors

Advanced Materials Technologies, EarlyView.
This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

High Magnetic Sensitivity at the Coercive Field Induced by Shear Horizontal SAW in Polycrystalline FeGa Films

Advanced Materials Technologies, EarlyView.
A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.

Spin‐Valley Polarization Control in WSe2 Monolayers using Photochemical Doping

Advanced Optical Materials, EarlyView.
A photochemical doping method is employed to modulate the spin‐valley polarization in WSe2 monolayers by tuning the carrier density from electron‐rich to hole‐rich regimes. This controlled doping enables a three‐fold variation in exciton polarization, revealing relaxation channels driven by scattering between excitons and charge carriers in two ...

Positivity properties of scattering amplitudes

Journal of High Energy Physics
We investigate positivity properties in quantum field theory (QFT). We provide evidence, and in some case proofs, that many building blocks of scattering amplitudes, and in some cases the full amplitudes, satisfy an infinite number of positivity ...
