In the twilight zone: An epidemiological study of sleep-related hallucinations

open access: yesComprehensive Psychiatry, 2021
Background: Few studies have investigated hallucinations that occur at the onset/offset of sleep (called hypnagogic/hypnopompic hallucinations; HHHs), despite the fact that their prevalence in the general population is reported to be higher than the ...

Modular prediction of protein structural classes from sequences of twilight-zone identity with predicting sequences

open access: yesBMC Bioinformatics, 2009
Background Knowledge of structural class is used by numerous methods for identification of structural/functional characteristics of proteins and could be used for the detection of remote homologues, particularly for chains that share twilight-zone ...

Diving deeper: Mesopelagic fish biomass estimates comparison using two different models

open access: yesFrontiers in Marine Science, 2023
A growing population on a planet with limited resources demands finding new sources of protein. Hence, fisheries are turning their perspectives towards mesopelagic fish, which have, so far, remained relatively unexploited and poorly studied.

Finding motifs in the twilight zone [PDF]

open access: yesBioinformatics, 2002
Abstract Motivation: Gene activity is often affected by binding transcription factors to short fragments in DNA sequences called motifs. Identification of subtle regulatory motifs in a DNA sequence is a difficult pattern recognition problem. In this paper we design a new motif finding algorithm that can detect very subtle motifs.

Cave-Dwelling Populations of the Monstrous Rainfrog (Craugastor pelorus) from Mexico

open access: yesDiversity, 2023
Amphibians are known cave dwellers, and a few anurans have shown to make exploratory or opportunistic use of subterranean environments. We report on the use of karst ecosystems and cavernicolous environments by the monstrous rainfrog Craugastor pelorus ...

Day–night and seasonal variations of a subterranean invertebrate community in the twilight zone

open access: yesSubterranean Biology, 2018
Being characterized by the absence of light and a reduced environmental cyclicity, the subterranean domain is generally regarded as temporally stable.

Oreo: detection of clones in the twilight zone [PDF]

open access: yesProceedings of the 2018 26th ACM Joint Meeting on European Software Engineering Conference and Symposium on the Foundations of Software Engineering, 2018
Source code clones are categorized into four types of increasing difficulty of detection, ranging from purely textual (Type-1) to purely semantic (Type-4). Most clone detectors reported in the literature work well up to Type-3, which accounts for syntactic differences.

On the signature of the cirrus twilight zone

open access: yesEnvironmental Research Letters, 2014
Cirrus clouds are known to play a key role in the climate system, but their overall effect on Earth’s radiation budget is not yet fully quantified. The uncertainties are, in part, due to ambiguities in cirrus extent or coverage. Here we show that despite

ConFunc—functional annotation in the twilight zone [PDF]

open access: yesBioinformatics, 2008
Abstract Motivation: The success of genome sequencing has resulted in many protein sequences without functional annotation. We present ConFunc, an automated Gene Ontology (GO)-based protein function prediction approach, which uses conserved residues to generate sequence profiles to infer function.

Cancer Chemopreventive and Anticancer Evaluation of Extracts and Fractions from Marine Macro- and Microorganisms Collected from Twilight Zone Waters around Guam

open access: yesNatural Product Communications, 2009
The cancer chemopreventive and cytotoxic properties of 50 extracts derived from Twilight Zone (50–150 m) sponges, gorgonians and associated bacteria, together with 15 extracts from shallow water hard corals, as well as 16 fractions derived from the ...
