Time or Space? Relative Importance of Geographic Distribution and Interannual Variation in Three Lineages of the Ascidian Pyura chilensis in the Southeast Pacific Coast

open access: yesFrontiers in Marine Science, 2021
Spatial and temporal variation of environmental parameters can affect dispersal, recruitment and population persistence of marine benthic species. Studies including inter-annual comparisons of genetic structure often indicate high/moderate temporal ...

Resource amount and discontinuity influence flight and reproduction in Hippodamia convergens (Coleoptera: Coccinellidae)

open access: yesEcosphere, 2022
Industrial‐scale agriculture creates a mosaic of large monocultures in the landscape, where seasonal cropping cycles generate discontinuous resource availability for insect predators both spatially and temporally.

A modal logic with temporal variables. [PDF]

open access: yesNotre Dame Journal of Formal Logic, 1978
There appear thus far to have been five general methods suggested in the literature for formalizing indeterministic tense-modal logics. The first consists in the introduction of a third truth-value, but this has the absurb consequence that the law of non-contradiction must be denied since the conjunction of any two propositions having the indeterminate

Wave Energy Resource Assessment for Small-Scale WEC near a Harbour

open access: yesJournal of Marine Science and Engineering, 2022
Accurate evaluations of the available and technically exploitable wave energy resources are fundamental to optimise the design and implementation of energy converters in the marine environment.

Altered static and dynamic intrinsic brain activity in unilateral sudden sensorineural hearing loss

open access: yesFrontiers in Neuroscience, 2023
IntroductionSudden sensorineural hearing loss (SSHL) is a critical otologic emergency characterized by a rapid decline of at least 30 dB across three consecutive frequencies in the pure-tone audiogram within a 72-hour period.

X-ray Variability Characteristics of the Seyfert 1 Galaxy NGC 3783 [PDF]

open access: yes, 2005
We have characterized the energy-dependent X-ray variability properties of the Seyfert~1 galaxy NGC 3783 using archival XMM-Newton and Rossi X-ray Timing Explorer data.

Temporal Variability of Cortical Gyral-Sulcal Resting State Functional Activity Correlates With Fluid Intelligence

open access: yesFrontiers in Neural Circuits, 2019
The human cerebral cortex is highly convoluted as convex gyri and concave sulci. In the past decades, extensive studies have consistently revealed substantial differences between gyri and sulci in terms of genetics, anatomy, morphology, axonal fiber ...

Sky Variability in the y Band at the LSST Site [PDF]

open access: yes, 2010
We have measured spatial and temporal variability in the y band sky brightness over the course of four nights above Cerro Tololo near Cerro Pachon, Chile, the planned site for the Large Synoptic Survey Telescope (LSST).

Extracting Additional Information From Biotic Index Samples [PDF]

open access: yes, 2017
Macroinvertebrates were collected from a small midwestern stream over a 3-year period as part of a non-point source pollution study. Temporal and spatial variability in standard biotic index values (BIs) were computed and compared with variability ...
