On the Global Asymptotic Stability of an Infection‐Age‐Structured Competitive Model
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We investigate an infection‐age‐structured competitive epidemiological model involving multiple strains. While classical results establish competitive exclusion when a unique maximal basic reproduction number exists, we provide here a complete characterization of the asymptotic behavior for an arbitrary number of populations without assuming ...

PLoS ONE, 2007 The 2.7 A crystal structure of the 55-kDa N-terminal breakage-reunion domain of topoisomerase (topo) IV subunit A (ParC) from Streptococcus pneumoniae, the first for the quinolone targets from a gram-positive bacterium, has been solved and reveals a ...

Theories of care help explain a peri‐urban tree diversity paradox
People and Nature, EarlyView.Abstract Since diversity is often a management objective for peri‐urban tree communities on public land, one might expect to find greater diversity there than on private land, where such objectives are less common. However, this expectation rests on an assumption that people control diversity towards objectives, overlooking the role of relationships ...

Planting for healthy air: Urban biodiversity enhances natural chemical environments
PLANTS, PEOPLE, PLANET, EarlyView.Cities urgently need nature to improve public health, support biodiversity, and increase resilience to climate change. Yet not all green spaces offer the same benefits. In this study, we show that more diverse urban plantings create richer “chemical environments”; subtle, naturally scented atmospheres formed by plant emissions that can influence how ...

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow
Remote Sensing in Ecology and Conservation, EarlyView.This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Hadron physics at J-PARC [PDF]
AIP Conference Proceedings, 2012 The Japan Proton Accelerator Research Complex, J‐PARC, has just finished its phase‐1 construction, and the proton beams have been delivered to the experimental facilities. The hadron experimental hall (Hadron Hall) is one of the experimental facilities at J‐PARC, where secondary beams such as pions and kaons, as well as the primary proton beams, will ...

Remote 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.

Association between mutations in gyrA and parC genes of Acinetobacter baumannii clinical isolates and ciprofloxacin resistance [PDF]
Iranian Journal of Basic Medical Sciences, 2015 Objective(s): We investigated the contribution of gyrA and parC mutational mechanism in decreased ciprofloxacin susceptibility of Acinetobacter baumannii isolated from burn wound infections.
