Abundance Gradients and the Formation of the Milky Way [PDF]

, 2001
In this paper we adopt a chemical evolution model, which is an improved version of the Chiappini, Matteucci and Gratton (1997) model, assuming two main accretion episodes for the formation of the Galaxy.

The HubBLe Trial: haemorrhoidal artery ligation (HAL) versus rubber band ligation (RBL) for symptomatic second- and third-degree haemorrhoids: a multicentre randomised controlled trial and health-economic evaluation

Health Technology Assessment, 2016
Background: Optimal surgical intervention for low-grade haemorrhoids is unknown. Rubber band ligation (RBL) is probably the most common intervention. Haemorrhoidal artery ligation (HAL) is a novel alternative that may be more efficacious.

Revealing the cosmic web dependent halo bias

, 2017
Halo bias is the one of the key ingredients of the halo models. It was shown at a given redshift to be only dependent, to the first order, on the halo mass.

On the integrability of halo dipoles in gravity

, 1996
We stress that halo dipole components are nontrivial in core-halo systems in both Newton's gravity and General Relativity. To this end, we extend a recent exact relativistic model to include also a halo dipole component. Next, we consider orbits evolving

Quantifying Within-Flight Variation in Land Surface Temperature from a UAV-Based Thermal Infrared Camera

Drones, 2023
Land Surface Temperature (LST) is a key variable used across various applications, including irrigation monitoring, vegetation health assessment and urban heat island studies. While satellites offer moderate-resolution LST data, unmanned aerial vehicles (

The distribution of red and blue galaxies in groups: an empirical test of the halo model

, 2004
The popular halo model predicts that the power spectrum of the galaxy fluctuations is simply the sum of the large scale linear halo-halo power spectrum and the weighted power spectrum of the halo profile.

Core Deformation in the Two-Neutron Halo Nucleus, 11Li by Using Faddeev Equation [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2017
The properties of the two-neutron halo nucleus 11Li are investigated. The calculations are performed using the Faddeev equation with core excitation and Woods-Saxon potential. The core has been deformed and allowed to be excited to first 2+ state.

Characterization, Antibiofilm, and Depolymerizing Activity of Two Phages Active on Carbapenem-Resistant Acinetobacter baumannii

Frontiers in Medicine, 2020
Acinetobacter baumannii is a leading cause of healthcare-associated infections worldwide. Its various intrinsic and acquired mechanisms of antibiotic resistance make the therapeutic challenge even more serious. One of the promising alternative treatments

Halo exclusion criteria impacts halo statistics [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT Every halo-finding algorithm must make a critical yet relatively arbitrary choice: it must decide which structures are parent haloes, and which structures are subhaloes of larger haloes. We refer to this choice as percolation. We demonstrate that the choice of percolation impacts the statistical properties of the resulting halo ...
