Random discrete probability measures based on a negative binomial process

Canadian Journal of Statistics, EarlyView.
Abstract A distinctive functional of the Poisson point process is the negative binomial process for which the increments are not independent but are independent conditional on an underlying gamma variable. Using a new point process representation for the negative binomial process, we generalize the Poisson–Kingman distribution and its corresponding ...

Galaxy Zoo: morphologies derived from visual inspection of galaxies from the Sloan Digital Sky Survey [PDF]

, 2008
In order to understand the formation and subsequent evolution of galaxies one must first distinguish between the two main morphological classes of massive systems: spirals and early-type systems.

Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

ChemPlusChem, EarlyView.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

Comparative ligand structural analytics illustrated on variably glycosylated MUC1 antigen–antibody binding

Beilstein Journal of Organic Chemistry, 2020
When faced with the investigation of the preferential binding of a series of ligands against a known target, the solution is not always evident from single structure analysis.

Multiwavelength Study of Massive Galaxies at z~2. I. Star Formation and Galaxy Growth [PDF]

, 2007
Examining a sample of massive galaxies at 1.4 < z < 2.5 with KVega < 22 from GOODS, we compare photometry from Spitzer at mid- and far-IR to submillimeter, radio, and rest-frame UV wavelengths, to test the agreement between different tracers of star ...

Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers

Contributions to Plasma Physics, EarlyView.
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

Detecting Wandering Intermediate-Mass Black Holes with AXIS in the Milky Way and Local Massive Galaxies

Universe
This white paper explores the detectability of intermediate-mass black holes (IMBHs) wandering in the Milky Way (MW) and massive local galaxies, with a particular emphasis on the role of AXIS.

Separating intrinsic alignment and galaxy-galaxy lensing

, 2012
The coherent physical alignment of galaxies is an important systematic for gravitational lensing studies as well as a probe of the physical mechanisms involved in galaxy formation and evolution.

Early in‐hospital treatment of acute heart failure. Part 2 of the international expert opinion series on AHF management

ESC Heart Failure, EarlyView.
This state‐of‐the‐art review outlines a practical, evidence‐based framework for early acute heart failure management to address critical gaps in current guidance and improve early treatment outcomes. Key components include early identification of co‐existing conditions, bedside haemodynamic profiling, a structured diagnostic approach incorporating both

Integrated trajectories of systolic and diastolic function differentially associate with risk for heart failure with preserved and reduced ejection fraction and proteomic profiles

European Journal of Heart Failure, EarlyView.
Graphical overview of derivation and testing of multiparametric trajectories of cardiac function. This study identified six trajectories of LV systolic and diastolic function from mid‐ to late‐life. Predicted trajectory from single echocardiogram identified four trajectories at differential risk for HFpEF and HFrEF.
