Exploring feature variability in digitally captured signatures—Part I: Variability in genuine signatures and the effects of collection sessions and writing position

Journal of Forensic Sciences, EarlyView.
Abstract Digitally captured signatures (DCSs) pose new challenges for forensic handwriting examination compared with paper‐based signatures. While DCSs provide spatial coordinates, time and force values for forensic examination, the variability of the features derived from these data remains insufficiently understood.

Exploring feature variability in digitally captured signatures—Part II: Discrimination between genuine and simulated signatures and the effects of collection sessions and writing position

Journal of Forensic Sciences, EarlyView.
Abstract This study investigated the discrimination between genuine and simulated digitally captured signatures (DCSs) to support their forensic examination. The dataset included genuine questioned signatures from 65 writers, collected across multiple sessions and in three writing positions, together with reference signatures collected in the standard ...

Concrete production using marble powder and marble coarse aggregates: an analysis of mechanical properties and sustainability

Budownictwo i Architektura
The growing demand for concrete driven by infrastructure and urbanization puts pressure on natural resources and harms the ecosystem. Using recycled materials like waste marble powder (WMP) and marble coarse aggregates (MCA) in concrete can address this

Determinants of case outcomes in Rwanda's postgenocide gacaca courts

Criminology, EarlyView.
Abstract Transitional justice trials have become a central mechanism for addressing mass violence and human rights violations, yet little is known about the determinants of case outcomes within these courts—particularly in domestic contexts. This study examines Rwanda's gacaca courts, a localized transitional justice system that tried people suspected ...

Junctional sensitivity and atrophy progression rate of geographic atrophy secondary to age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the relationship between the baseline junctional retinal sensitivity measured with microperimetry and the atrophy progression rate in eyes with geographic atrophy (GA) secondary to age‐related macular degeneration. Methods In this prospective cohort study, patients with GA were examined with fundus autofluorescence (FAF ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
