Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

On the complexity of the line-distinguishing-coloring of simple graphs [PDF]

open access: yes, 1996
In this paper we consider the line-distinguishing coloring of simple graphs. The line-distinguishing chromatic number is the smallest number of colors which is necessary to color the vertices of a simple graph where each pair of colors appears together ...

A Label‐Free Ultraviolet Photoacoustic Microscopy Enables Nuclear Imaging and Toxicity Assessment in an Intact Brain Organoid

open access: yesSmall, EarlyView.
Ultraviolet photoacoustic microscopy enables label‐free visualization of nuclear morphology in intact human brain organoids. By exploiting endogenous nucleic acid absorption at 266 nm, this approach resolves individual nuclei without staining or sectioning.

Chromatic graph theory [PDF]

open access: yes, 2008
Beginning with the origin of the four color problem in 1852, the field of graph colorings has developed into one of the most popular areas of graph theory.

Kinetically Controlled Direct In Situ Photolithography of Perovskite Color‐Conversion Layers

open access: yesSmall, EarlyView.
Kinetically controlled direct in situ photolithography (KC‐ISP) enables high‐resolution patterning of micrometer‐thick perovskite color‐conversion layers. By regulating thiol–ene reaction kinetics and redistributing precursors within the polymer matrix, lateral curing is suppressed and spatially selective crystallization is achieved.

Metal‐Free Ternary‐Composite Aerogel Based on Graphitic Carbon Nitride, Graphene Oxide, and β‐Cyclodextrin for Synergistic Adsorption and Photodegradation of Organic Dyes

open access: yesSmall, EarlyView.
A novel metal‐free g‐C3N4/GO/β‐CD aerogel exhibits a high adsorption capacity of 653.2 mg/g for RhB. The synergistic adsorption‐degradation effect of the aerogel enables the complete elimination of organic dyes. Fixed‐bed and recyclability tests demonstrate its potential for continuous industrial wastewater treatment.

A neutron microscope using a nested Wolter‐I condenser and a bank of diffractive–refractive achromatic objectives

open access: yesJournal of Applied Crystallography, EarlyView.
A neutron microscope is presented comprising a Wolter‐I nested mirror optic as condenser and a 2D array of neutron achromats as objective.We present a nested Wolter‐I mirror design for a neutron condenser, which is based on established X‐ray telescope technology.

∆ + 300 is a bound on the adjacent vertex distinguishing edge chromatic number [PDF]

open access: yes, 1999
An adjacent vertex distinguishing edge-coloring or an avd-coloring of a simple graph G is a proper edge-coloring of G such that no pair of adjacent vertices meets the same set of colors.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

open access: yesAgricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

The Utility of Artificial Intelligence in Dermatology Training and Practice: A National, Cross‐Sectional Study

open access: yesAustralasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Artificial intelligence (AI) is increasingly relevant to dermatology, yet clinical integration depends on workforce readiness. While the technical performance of AI tools is well described, the perspectives of dermatology trainees, who will shape future adoption, are less well understood.
