To address the technical challenges associated with determining the chronological order of overlapping stamps and textual content in forensic document examination, this study proposes a novel non-destructive method that integrates hyperspectral imaging (HSI) with convolutional neural networks (CNNs). A multi-type cross-sequence dataset was constructed, comprising 60 samples of handwriting-stamp sequences and 20 samples of printed text-stamp sequences, all subjected to six months of natural aging. Spectral responses were collected across the 400-1000 nm range in the overlapping regions.

This work investigates the problem of collaborative target tracking by multiple unmanned aerial vehicles (UAVs) in maritime search and rescue. A class of time-varying (TV) convex optimization problems with inequality constraints is presented. In contrast to existing studies that address UAV-based maritime search and rescue under fixed wind speed conditions, this study also explores collaborative target tracking by UAVs under varying wind speed conditions.

Single-arm control trials are increasingly proposed as a potential approach for treatment evaluation. However, the limitations of this design restrict its methodological acceptability. Regulatory agencies have raised concerns about this approach, although it is sometimes required in applications based solely on such studies.

Background: Cardiovascular complications are the leading cause of mortality following liver transplantation (LT) in patients with acute-on-chronic liver failure (ACLF). However, the extent of cardiac impairment in these patients remains unclear. Current risk models, including the CLIF-C-organ failure (CLIF-C-OF), NACSELD-ACLF, and the novel Sundaram ACLF-LT-mortality (SALT-M) scores primarily focus on blood pressure and the use of cardiovascular drugs, without directly assessing biomarkers of cardiac injury.

We analyze the spin-glass transition in a field in finite dimension [Formula: see text] below the upper critical dimension directly at zero temperature using a recently introduced perturbative loop expansion around the Bethe lattice solution. The expansion is generated by the so-called [Formula: see text]-layer construction, and it has [Formula: see text] as the associated small parameter. Computing analytically and numerically these nonstandard diagrams at first order in the [Formula: see text] expansion, we construct an [Formula: see text]-expansion around the upper critical dimension [Formula: see text], with [Formula: see text].
