Inverse Kernel Identification in a Time‐Fractional Integro‐Differential Equation
ABSTRACT This article investigates a fractional diffusion‐wave model incorporating memory effects. We first analyze the direct problem and establish the existence, uniqueness, and regularity of its solution under suitable conditions. The primary focus is on an inverse problem, in...

Abstract Southwest and Central Asia were pivotal regions for the domestication and dispersal of domestic herbivores. Here we investigate long-term variation in bony labyrinth morphology of domestic bovids (sheep, goats and cattle) across the last 10 000 years. We focused on the o...

Charge-Carrier Behavior and Molecular Interface Engineering in Perovskite Light-Emitting Diodes
Abstract Molecular interface engineering has become increasingly important for improving the efficiency and stability of perovskite light-emitting diodes (PeLEDs). Although highly emissive perovskite materials have advanced rapidly, their translation into high-performance devices...

In post-training compression of Transformer models, the compression ratio or pruning rate is often predetermined and does not directly take into account the memory capabilities of the target hardware. This work introduces a cache-aware post-training compression framework for CPU-...

Abstract The portion of the Riparo l’Oscurusciuto (Italy) stratigraphic sequence so far excavated provides an outstanding record of the local population history between ca. 55 − 42 kya BP: a key period for understanding the end of the Middle Palaeolithic and the onset of the Uppe...

A De Giorgi conjecture on the regularity of minimizers of Cartesian area in 1D
Abstract We prove a $$C^{1,1}$$ C 1 , 1 -regularity result for minimizers of the functional $$ \int _I \sqrt{1+|Du|^2} + \int _I |u-g|ds,\quad u\in BV(I), $$ ∫ I 1 + | D u | 2 + ∫ I | u - g | d s , u ∈ B V ( I ) , provided $$I\subset \mathbb {R}$$ I ⊂ R is a bounded open interval...

The Emergence of Pottery in Southern Iran: Evidence from the Neolithic Site of Tol-e Sangi
Abstract The emergence and spread of pottery production in Southwest Asia is a key topic in Neolithic archaeology, as it can provide valuable information about the technological developments and cultural changes of early societies. Archaeological excavations at the Tol-e Sangi in...

Circular-orbit dynamics and QPO constraints in static Einstein–scalar–Gauss–Bonnet black holes
Abstract Einstein–scalar–Gauss–Bonnet (EsGB) gravity provides a physically motivated framework for testing strong-field deviations from the Schwarzschild geometry through scalar hair. We study neutral-particle circular motion and high-frequency quasi-periodic oscillations (HF-QPO...
