Phylogenetic revision of Gymnotidae (Teleostei: Gymnotiformes), with descriptions of six subgenera.

open access: yesPLoS ONE, 2019
The diversity of gymnotid electric fishes has been intensely studied over the past 25 years, with 35 species named since 1994, compared to 11 species in the previous 236 years.

Reconnection Outflows and Current Sheet Observed with Hinode/XRT in the 2008 April 9 "Cartwheel CME" Flare

open access: yes, 2010
Supra-arcade downflows (SADs) have been observed with Yohkoh/SXT (soft X-rays (SXR)), TRACE (extreme ultra-violet (EUV)), SoHO/LASCO (white light), SoHO/SUMER (EUV spectra), and Hinode/XRT (SXR).

Another Deleuzian Resnais: l'année dernière à Marienbad as conflict between sadism and masochism [PDF]

open access: yes, 2008
The Deleuzian reading of L'Année dernière à Marienbad proposed here draws less on what has become a virtually canonical concept in film studies – Deleuze's time-image – than on a much earlier work by the same author, Masochism, which treats sadism and ...

Unlocking the potential of stimuli‐responsive liquid crystal polymer bio‐interfaces for adaptive cell modulation

open access: yesResponsive Materials, EarlyView.
This Perspective discusses the potential of stimuli‐responsive liquid crystal polymer bio‐interfaces in modulating cell behavior as next generation dynamic artificial scaffolds. Unlike current artificial biomaterials that have static properties, LCPs offer fast, reversible, and spatially programmable deformation that reflects the dynamic properties of ...

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

Semi Ideal on Supra Topological Space

open access: yesTikrit Journal of Pure Science, 2023
In this paper we introduces the ideal on supra  topological space and we shall discuss the properties of this space. In this space we introduces  two operators ( )  and   . A generalized set has also been introduced in this space ( )  and  .

Sleep Slow Wave‐Bistability and the Connection Between the Sleeping Brain and the Environment—Neurobiological Considerations

open access: yesJournal of Sleep Research, Volume 35, Issue 2, April 2026.
Bistability is an inherent working mode of NREM sleep. Those bistable patterns ‐ sleep slow waves, K‐complexes, and the cyclic alternating pattern (on a longer, several seconds' time‐scale) ‐ have a double function; they protect sleep and provide an interface between the brain and the environment for information‐transfer during sleep.

A fast current-driven instability in relativistic collisionless shocks

open access: yes, 2014
We report here on a fast current-driven instability at relativistic collisionless shocks, triggered by the perpendicular current carried by the supra-thermal particles as they gyrate around the background magnetic field in the shock precursor.

Supra b-irresolutness and Supra b-connectedness on Topological Space

open access: yesKyungpook mathematical journal, 2013
In this paper, the concept of supra b-irresolute maps is introduced and several properties of it is investigated. Furthermore, the notion of supra b-connectedness is defined and researched by means of supra b-separated sets.

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...
