Experimental Assessment of the Effects of Substrate Choice on the Duration of Chemical Signals in Fecal Scent‐Marks of Free‐Ranging Iberian Wolves

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Chemical communication, typically based on feces, urine, and glandular secretions, often deposited as substrate scent marks, plays a key role in social organization and communication among many mammals, especially carnivores. This study assesses experimentally whether the type of substrate chosen for fecal deposition and the temperature ...

Properly Colored Cycles in Edge‐Colored Balanced Bipartite Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT Let G n , n c ${G}_{n,n}^{c}$ denote a (not necessarily properly) edge‐colored balanced bipartite graph on 2 n $2n$ vertices, that is, in which every edge is assigned a color. A cycle C $C$ in G n , n c ${G}_{n,n}^{c}$ is called properly colored if any two consecutive edges of C $C$ have distinct colors. A properly colored cycle‐factor of G n ,

Domination in 4‐Regular Graphs With No Induced 4‐Cycles

Journal of Graph Theory, EarlyView.
ABSTRACT A set S $S$ of vertices in a graph G $G$ is a dominating set of G $G$ if every vertex not in S $S$ is adjacent to a vertex in S $S$. The domination number of G $G$, denoted by γ ( G ) $\gamma (G)$, is the minimum cardinality of a dominating set in G $G$.

Low‐value care and variation in practice in the care of children hospitalized with bronchiolitis in Canada (CareBEST): Protocol for a multi‐center prospective cohort study

Journal of Hospital Medicine, EarlyView.
Abstract Introduction Low‐value care refers to health services for which the potential harms or costs outweigh the benefits of use. Bronchiolitis is the most common and among the most costly causes of pediatric hospitalizations. Evidence consistently shows that many common tests and treatments used to manage bronchiolitis do not improve outcomes ...

Prevalence and costs of US pediatric hospitalizations, 2022

Journal of Hospital Medicine, EarlyView.
Abstract Background Pediatric hospitalizations represent an evolving component of US healthcare utilization. The coronavirus disease 2019 (COVID‐19) pandemic hastened rising mental health visits and shrinking rural hospital capacity. Understanding contemporary patterns in pediatric hospitalizations is critical to inform health system planning and ...

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

International Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical

Interactive effects of environmental microplastics and 2,4-dichlorophenoxyacetic acid (2,4-D) on the earthworm Eisenia andrei.

Journal of Hazardous Materials, 2021
Given the wide use of plastic and pesticides in agriculture, microplastics (MP) and the herbicide 2,4 dichloro-phenoxy-acetic acid (2-4-D) can be present simultaneously in soil. Nevertheless, little is known about their combined toxicity.

Morphological, behavioral and genotoxic effects of glyphosate and 2,4-D mixture in tadpoles of two native species of South American amphibians.

Environmental Toxicology and Pharmacology, 2021
Pesticide contamination is an important factor in the global decline of amphibians. The herbicides glyphosate and 2,4-D are the most applied worldwide. These herbicides are often found in surface waters close to agricultural areas.
