Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Global trends in the production and use of DDT for control of malaria and other vector-borne diseases

Malaria Journal, 2017
Background DDT was among the initial persistent organic pollutants listed under the Stockholm Convention and continues to be used for control of malaria and other vector-borne diseases in accordance with its provisions on acceptable purposes.

Enhancing Hydrophobic Stability of Silicone Rubber Insulators Under High‐Voltage Direct Current Stress Through Optimised Nano‐Fumed Silica Surface Area: A Dynamic Drop Test Study

High Voltage, EarlyView.
ABSTRACT The long‐term hydrophobic stability of silicone rubber (SiR) insulators is essential for their reliability in high‐voltage direct current (HVDC) applications. This study investigates the effect of nano‐silica fillers with varying specific surface areas (SSA = 120, 200 and 300 m2/g) and different concentrations of alumina trihydrate (ATH ...

Developmental exposure to low doses of dichlorodiphenyltrichloroethane disrupts functional and morphologic maturation of the spleen in prepubertal rats

Russian Open Medical Journal
Dichlorodiphenyltrichloroethane (DDT) is a versatile persistent pollutant with endocrine disrupting properties and an alleged immune modulator. Objective — to evaluate the parameters of functional and morphological maturation of the spleen in prepubertal

Renormalization techniques for inflation systems and some of their applications

Acta Crystallographica Section A, EarlyView.
In this work, renormalization methods for quantities related to the diffraction of inflation systems are surveyed.Exact renormalization techniques are important and powerful, particularly for inflation‐generated systems. We review recent results in this direction.

Nonmalarial Infant Deaths and DDT Use for Malaria Control

Emerging Infectious Diseases, 2003
Although dichlorodiphenyl trichloroethane (DDT) is being banned worldwide, countries in sub-Saharan Africa have sought exemptions for malaria control. Few studies show illness in children from the use of DDT, and the possibility of risks to them from DDT

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Novel approaches for drug development against chronic primary pain: A systematic review

British Journal of Pharmacology, EarlyView.
Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.

Metabolic and target-site mechanisms combine to confer strong DDT resistance in Anopheles gambiae.

PLoS ONE, 2014
The development of resistance to insecticides has become a classic exemplar of evolution occurring within human time scales. In this study we demonstrate how resistance to DDT in the major African malaria vector Anopheles gambiae is a result of both ...

Edge‐preserving noise for diffusion models

Computer Graphics Forum, EarlyView.
Abstract Classical diffusion models typically rely on isotropic Gaussian noise, treating all regions uniformly and overlooking structural information important for high‐quality generation. We introduce an edge‐preserving diffusion process that generalizes isotropic models via a hybrid noise scheme with an edge‐aware scheduler that smoothly transitions ...
