The Microvariable Activity of BL Lacertae [PDF]

open access: yesGalaxies, 2020
We report on seven nights of optical observation taken over a two-week period, and the resultant analysis of the intermediate-frequency peaked BL Lac object (IBL), BL Lac itself, at redshift z = 0.069. The microvariable behavior can be confirmed over the course of minutes for each night.

Microsatellite typing of avian clinical and environmental isolates of Aspergillus fumigatus [PDF]

open access: yes, 2011
Aspergillosis is one of the most common causes of death in captive birds. Aspergillosis in birds is mainly caused by Aspergillus fumigatus, a ubiquitous and opportunistic saprophyte.

Linguistic and Sociolinguistic Aspects of Variation in the Eastern Cape: Complexities of Xhosa Language Use

open access: yesStudia Orientalia Electronica, 2018
This paper presents the results of a micro-variation project in which linguistic diversity of the Eastern Cape of South Africa is examined. It shows that regional variation in the Xhosa dialect cluster is minimal and that many older forms and sounds that

Intranight optical variability of radio-quiet BL Lacertae objects

open access: yes, 2015
Aims: Intranight variation (or microvariation) is a common phenomenon of radio-loud BL Lac objects. However, it is not clear whether the recently found radio-quiet BL Lac objects have the same properties.

The Syntactic Status of Subject Clitics: A Problem from Venetan SE‐Constructions

open access: yesTransactions of the Philological Society, Volume 124, Issue 1, Page 144-167, March 2026.
Abstract This article reopens the discussion on the syntax of subject clitics (SCLs) in Venetan dialects by providing a problematic piece of data and outlining its theoretical consequences. New evidence from se‐constructions in Alto Polesine Venetan (APV) shows that SCLs resist a unitary categorisation even within the same dialect group: in varieties ...

Optical microvariability of southern AGNs [PDF]

open access: yesAstronomy and Astrophysics Supplement Series, 1999
We present results of a search for optical mi- crovariability in a selected sample of 23 southern AGNs, which includes both radio-quiet and radio-loud objects. Microvariations were clearly detected in 60% of the radio- loud sources, with amplitudes from 2.2% up to 8% within a single night.

Advancing Cave Survey Methods: High‐Precision Mapping in Drakotrypa Cave, Greece

open access: yesArchaeological Prospection, Volume 33, Issue 1, Page 189-201, January/March 2026.
ABSTRACT Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features.

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yes, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Patterns of variation in existential constructions

open access: yesIsogloss, 2015
The main goal of the present paper is twofold: on the one hand, to highlight the patterns of variation among the existential constructions found in Italo-Romance and Sardinian dialects; on the other, to examine the observed microvariation in a ...

Phonetic and Phonological Research in Mai-Ndombe: A Few Preliminary Notes on Rhotics and Double-Articulations

open access: yesLanguages
Mai-Ndombe is one of the southwestern provinces of the Democratic Republic of Congo. Ecologically, it can be characterised as a transition zone between a moist, broadleaf rainforest ecotone in the north and shrubland/savannah areas in the south ...
