Ensembled evaluations of habitat suitability for prioritizing lesser prairie‐chicken conservation

Ecosphere
Populations of lesser prairie‐chickens (Tympanuchus pallidicinctus, hereafter “prairie‐chickens”) in the Mixed‐Grass Prairie Ecoregion of the southern Great Plains have been projected to go extinct in the next 100 years unless targeted conservation ...

Radio resource allocation in relay based OFDMA cellular networks

, 2010
PhDAdding relay stations (RS) between the base station (BS) and the mobile stations (MS) in a cellular system can extend network coverage, overcome multi-path fading and increase the capacity of the system.

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

Molecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Management implications of habitat selection by whooping cranes (Grus americana) on the Texas coast

Ecosphere
Effective habitat management for rare and endangered species requires a thorough understanding of their specific habitat requirements. Although machine learning models have been increasingly used in the analyses of habitat use by wildlife, the primary ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

False negatives – A false problem in studies of habitat selection?

Ideas in Ecology and Evolution, 2010
Habitat use and resource selection studies based on presence-only data often use simulated locations as a benchmark for comparison with locations where a species has been observed.

Abundant resources compensate for the uneven distribution of ungulates in desert grassland

Frontiers in Plant Science
IntroductionStrategically managing livestock grazing in arid regions optimizes land use and reduces the damage caused by overgrazing. Controlled grazing preserves the grassland ecosystem and fosters sustainability despite resource limitations.

On Production Function Estimation with Selectivity and Risk Considerations

In the estimation of production functions, ignoring risk considerations can cause inefficient estimates, while biased parameter estimates arise in the presence of sample selection.

Automatic resource specification generation for resource selection in large-scale distributed environments [PDF]

, 2007
With an increasing number of available resources in large- scale distributed environments, a key challenge is resource selection. First, we show why explicit resource selection is necessary to optimize application performance.
