Variability in the UV resonance lines of the cataclysmic variable V795 Herculis (PG-1711 + 336)
(1992)Variability in the UV resonance lines from the cataclysmic variable V795 Her is investigated on the basis of a total of 28 IUE SWP low-resolution spectra. Significant line profile fluctuations are evident in the C IV 1549 ... -
The variability in the UV resonance lines of the cataclysmic variables MU Cen, AH Her and QU Car
(1994)We present a time-variability study of the uV resonance lines Nv 1240, Si iv 1397 and C iv 1549 in the dwarf novae AH Her and MU Cen and the nova-like variable QU Car. The main findings are as follows. (i)Virtually no ... -
Variability of the Centimeter-Submillimeter Spectrum and Polarization of 3C 273 during Outburst
(1998)Centimeter to submillimeter total flux and polarization monitoring data are used to investigate the nature of a prominent flare in the quasar 3C 273 during 1995/6. After removal of the quiescent level, the resulting “flare ... -
A variable active galactic nucleus at $z=2.06$ triply-imaged by the galaxy cluster MACS J0035.4-2015
(2023-07-31)We report the discovery of a triply imaged active galactic nucleus (AGN), lensed by the galaxy cluster MACS J0035.4−2015 (z d = 0.352). The object is detected in Hubble Space Telescope imaging taken for the RELICS program. ... -
The variable infrared source near HH100
(1982)Photometric observations are presented which confirm the high variability, of up to 2.5 mag at K, of the IR source associated with the Herbig-Haro object HH100, and it is suggested that such a large variation must be a ... -
Variable star classification across the Galactic bulge and disc with the VISTA Variables in the Vía Láctea survey
(2021-10-30)We present VIVACE, the VIrac VAriable Classification Ensemble, a catalogue of variable stars extracted from an automated classification pipeline for the Vista Variables in the V\'ia L\'actea (VVV) infrared survey of the ... -
Variable Stars in the Quintuplet stellar cluster with the VVV Survey
(2016-10-21)The Quintuplet cluster is one of the most massive star clusters in the Milky Way, situated very close to the Galactic center. We present a new search for variable stars in the vicinity of the cluster, using the five-year ... -
Variable stars in the VVV globular clusters. II. NGC6441, NGC6569, NGC6626 (M28), NGC6656 (M22), 2MASS-GC02, and Terzan10
(2021-07-12)Context. The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. High densities of field stars in their surroundings complicate ... -
Variation in Black students’ conceptions of academic support
(2023-10-30)The persistence of degree‐awarding gaps and anti‐Black racism warrant an exploration of the quality and effectiveness of academic support offered to Black undergraduate students in British higher education, and how such ... -
Variation in eyespot populations; a field study

Variation in individual walking behaviour creates the impression of a Lévy flight
(2011-05-24)Many animal paths have an intricate statistical pattern that manifests itself as a power law-like tail in the distribution of movement lengths. Such distributions occur if individuals move according to a Lévy flight (a ... -
Variation in myoplasmic Ca2+ concentration during contraction and relaxation studied by the indicator fluo-3 in frog muscle fibres
(1994-07-01)1. The fluorescent dye fluo-3, in its permeant acetoxymethyl form, was used to monitor calcium transients during twitch and tetanus of single fibres isolated from the anterior tibialis muscle of Rana temporaria (2-5 degrees ... -
Variation in personality states as predicted by interpersonal context
(2019-01-01)Diary studies of personality have shown that personality is variable, and can help the person deal appropriately with the different interpersonal demands they encounter. This study aims to demonstrate how interpersonal ... -
Variation in the effects of three different breakfast meals on subjective satiety and subsequent intake of energy at lunch and evening meal
(2013-06-01)Purpose: To determine the relative impact of three iso-caloric breakfast meals, of variable composition, on satiety, hunger and subsequent intake of energy. Methods: In a three-way, crossover design, 30 healthy men (age ... -
Variation of the vertical distribution of Nabro volcano aerosol layers in the stratosphere observed by LIDAR
(2017-04-01)We present results of the vertical distribution variation of volcanic aerosol layers in the upper troposphere and lower stratosphere. The data were taken with our multiwavelength aerosol Raman lidar at Gwangju (35.10 N, ... -
Variation within and between Phytophthora species from rubber and citrus trees in China, determined by polymerase chain reaction using RAPDs
(1998-04)Variation among 39 isolates of Phytophthora a of six morphological species (P. citrophthora, P. parasitica, P. capsici, P. palmivora and P. meadii, from rubber and citrus trees, and P. colocasiae from tare) was studied ... -
