On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Fluorescent Supramolecular Gels Based on D‐Sorbitol Derivatives

open access: yesSmall, EarlyView.
Sugar‐based fluorescent low‐molecular‐weight gelators (LMWGs) DNapS, DBTDS, and MCumS, prepared by a green, scalable route, form supramolecular gels in water, organic, and deep eutectic solvents. MCumS yields solvent‐dependent nanofibrous networks and viscoelastic injectable eutectogels.

Inkjet‐Printed Physical Unclonable Functions For Secure Authentication

open access: yesSmall, EarlyView.
Herein, we propose a low‐cost authentication system based on a scalable fabrication technology and user friendly recognition system. It involves inkjet printing as a manufacturing method and an optical recognition system based on contour features extraction.

Terrain Synthesis and Authoring based on Iso‐Contours

open access: yesComputer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.

A Review on Image Processing and Fractal Analysis in Oral Potentially Malignant Disorders

open access: yesOral Diseases, EarlyView.
ABSTRACT Aim The clinical evaluation of patients with oral potentially malignant disorders is primarily based on physical examination and observable clinical features. Clinical photographs play a key role in patient monitoring and help identify signs that may indicate malignant transformation.

Modern microbial landscape: Aerial mapping of microbially induced sedimentary structures forming in a coastal sabkha

open access: yesSedimentology, EarlyView.
ABSTRACT Microbially induced sedimentary structures (MISS) are considered important for understanding primitive life on Earth and for guiding the search for life on other planets. These structures are regarded as macroscopic fossils of early communities of unicellular organisms that did not produce skeletons or shells. In this study, field observations
