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

open access: yesHealth 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.

The Excursion Set Theory of Halo Mass Functions, Halo Clustering, and Halo Growth [PDF]

open access: yes, 2006
I review the excursion set theory (EST) of dark matter halo formation and clustering. I recount the Press-Schechter argument for the mass function of bound objects and review the derivation of the Press-Schechter mass function in EST.

Mass Models for Spiral Galaxies from 2-D Velocity Maps

open access: yes, 2004
We model the mass distributions of 40 high surface brightness spiral galaxies inside their optical radii, deriving parameters of mass models by matching the predicted velocities to observed velocity maps.

Halo nevus [PDF]

open access: yesMedicinski Glasnik Specijalne Bolnice za Bolesti Štitaste Žlezde i Bolesti Metabolizma "Zlatibor"
Halo nevi (leukoderma acquisitum centrifugum, Sutton's nevus, leukopigmentary nevus, perinevoid vitiligo or perinevoid leukoderma) are melanocytic nevi surrounded by a halo of hypopigmentation or depigmentation.

Two Stellar Components in the Halo of the Milky Way

open access: yes, 2007
The halo of the Milky Way provides unique elemental abundance and kinematic information on the first objects to form in the Universe, which can be used to tightly constrain models of galaxy formation and evolution. Although the halo was once considered a

A Peculiar Halo [PDF]

open access: yesNature, 1920
ON March 16 I observed a peculiar halo here; its form is best shown by a rough sketch. The angles were taken with a pocket slide-rule held at arm's length, and are, therefore, only approximations, but the relative values are probably fairly correct. The halo was brightest at the point above the sun, and faded off somewhat on each side; it ended rather ...

Statistics of Substructures in Dark Matter Haloes [PDF]

open access: yes, 2011
We study the amount and distribution of dark matter substructures within dark matter haloes, using a large set of high-resolution simulations ranging from group size to cluster size haloes, and carried our within a cosmological model consistent with WMAP 7-year data. In particular, we study how the measured properties of subhaloes vary as a function of

Artificial Intelligence Approach for Classifying Images of Upper-Atmospheric Transient Luminous Events

open access: yesSensors
Transient Luminous Events (TLEs) are short-lived, upper-atmospheric optical phenomena associated with thunderstorms. Their rapid and random occurrence makes manual classification laborious and time-consuming.

On the integrability of halo dipoles in gravity

open access: yes, 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
