Functional brain network mechanism of executive control dysfunction in temporal lobe epilepsy

open access: yesBMC Neurology, 2020
Background Executive control dysfunction is observed in a sizable number of patients with temporal lobe epilepsy (TLE). Neural oscillations in the theta band are increasingly recognized as having a crucial role in executive control network.

Increasing eutrophication driven by the increase of phosphate discharge in a subtropical bay in the past 30 years

open access: yesFrontiers in Marine Science, 2023
Although great efforts have been made to decrease nutrient (notably nitrogen and phosphorus) loads and lighten related environmental damages, coastal eutrophication remains a persistent environmental crisis.

Variations on a theme [PDF]

open access: yesCanadian Medical Association Journal, 2021
The facility was far uptown. We all dozed off during the long ride, and by the time the train lurched into the station, we were groggy. Though we were not native New Yorkers, three years in the city was enough to develop that uncanny ability to emerge from sleep just before missing your stop ...

Variations of the IMF [PDF]

open access: yes, 2005
(abridged) The {stellar IMF} has been found to be essentially invariant. While some apparent differences are seen, the uncertainties inherent to this game do not allow a firm conclusion to be made that the IMF varies systematically with conditions. The IMF integrated over entire galaxies, however, is another matter.

Is variation in biological variation a problem? [PDF]

open access: yesAnnals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2007
nent of the total variation (CVT) and can be considered in terms of intra-individual (BVI) and inter-individual (BVG) variation. For a given individual the BVI can be determined from the total variation (CVT) and the analytical variation (CVA). Since the CVA can be readily calculated for most analytes the BVI can be readily determined.

Variation in form versus variation in meaning [PDF]

open access: yesLingua, 2004
Abstract The aim of this introductory article is to provide a background to the articles contained in this special issue of Lingua that centers around variation in form, variation in meaning, and markedness. Theoretical and empirical considerations are brought together in this special issue in which the linguistic disciplines that are covered ...

On the variational principle [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 1974
AbstractThe variational principle states that if a differentiable functional F attains its minimum at some point ū, then F′(ū) = 0; it has proved a valuable tool for studying partial differential equations. This paper shows that if a differentiable function F has a finite lower bound (although it need not attain it), then, for every ϵ > 0, there ...

Case discussions of missed traumatic fractures on computed tomography scans

open access: yesSouth African Journal of Radiology, 2022
Radiological diagnostic errors are common and may have severe consequences. Understanding these errors and their possible causes is crucial for optimising patient care and improving radiological training.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

open access: yesPopulation Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
