Mapping accretion and its variability in the young open cluster NGC 2264: a study based on u-band photometry [PDF]

, 2014
We aim at characterizing the accretion properties of several hundred members of the star-forming cluster NGC 2264 (3 Myr). We performed a deep u,g,r,i mapping and a simultaneous u+r monitoring of the region with CFHT/MegaCam in order to directly probe ...

Acclimatization Drives Differences in Reef-Building Coral Calcification Rates

Diversity, 2020
Coral reefs are susceptible to climate change, anthropogenic influence, and environmental stressors. However, corals in Kāneʻohe Bay, Hawaiʻi have repeatedly shown resilience and acclimatization to anthropogenically-induced rising temperatures and ...

General relativistic radiative transfer: formulation and emission from structured tori around black holes

, 2012
We construct a general relativistic radiative transfer (RT) formulation, applicable to particles with or without mass in astrophysical settings. Derived from first principles, the formulation is manifestly covariant.

Whole Body Nutrient Accretion, Growth Performance and Total Tract Nutrient Retention Responses of Broilers to Supplementation of Xylanase and Phytase Individually or in Combination in Wheat-Soybean Meal Based Diets

The Journal of Poultry Science, 2008
Growth performance, total tract nutrient retention and whole body nutrient accretion rates responses of broilers to supplementation of enzymes containing phytase or xylanase activities were investigated using 300 broilers.

Phantom Accretion onto the Schwarzschild de-Sitter Black Hole

, 2011
We deal with phantom energy accretion onto the Schwarzschild de-Sitter black hole. The energy flux conservation, relativistic Bernoulli equation and mass flux conservation equation are formulated to discuss the phantom accretion.

The Three Dimensional Structure of EUV Accretion Regions in AM Herculis Stars: Modeling of EUV Photometric and Spectroscopic Observations [PDF]

, 1998
We have developed a model of the high-energy accretion region for magnetic cataclysmic variables and applied it to {\it Extreme Ultraviolet Explorer} observations of 10 AM Herculis type systems.

Oncogenic NRAS Mutation in Incipient Sarcomatous Transformation of Cystic Nephroma From a Patient With DICER1‐Related Tumor Predisposition Syndrome

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Anaplastic sarcoma of the kidney (ASK) is a DICER1‐associated malignant tumor presumed to arise in a benign precursor, pediatric cystic nephroma (PCN). However, the initial oncogenic alteration(s) associated with malignant transformation are unknown.

Dissipationless disk accretion [PDF]

Astronomy Reports, 2005
17 pages, 6 figures, published in Astronomy Reports, Vol.49, No.1, 2005, p.57 (submitted September 13, 2003). Unfortunately, we did not upload the paper to astro-ph before, but since the topic is now of interest we feel that the paper would benefit the ...

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Gas Accretion in Star-Forming Galaxies

, 2016
Cold-mode gas accretion onto galaxies is a direct prediction of LCDM simulations and provides galaxies with fuel that allows them to continue to form stars over the lifetime of the Universe.
