Measurement of the electric field distribution in streamer discharges

open access: yesPhysical Review Research
Using electric field induced second harmonic generation (E-FISH), we performed direction-resolved absolute electric field measurements on single-channel streamer discharges in 70 mbar (7 kPa) air with 0.2 mm and 2 ns resolutions.

A Mathematical Model for Electrolocation in Weakly Electric Fishes

open access: yesBIO Web of Conferences, 2016
Weakly electric fishes usually live in the rivers of Africa and South America. They are able to orient themselves thanks to an electric sense, called electrolocation, that consist of emitting an electric field and sensing it at the surface of their skin.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Electrosensory Frequency and Intensity Discrimination in the Wave-Type Electric Fish Eigenmannia [PDF]

open access: yes, 1991
Eigenmannia's frequency and intensity discrimination thresholds were determined for a range of seven frequencies (50-1700Hz), centered on a fish's individual discharge frequency, using a conditioned go/no-go paradigm.

Personality effects on spatial learning: Comparisons between visual conditions in a weakly electric fish

open access: yes, 2017
Recent research has explored links between cognition and personality, with prominent hypotheses proposing that personality drives consistent individual differences in cognitive function.

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Observations on the downstream movements of brown trout fry (Salmo trutta L.)in the Lissuraga [Translation from: Bulletin Francais de la Pisciculture No.274 1-17, 1979] [PDF]

open access: yes, 1980
The phenomenon of the downstream movement of brown trout fry has been noticed for a very long time by fish biologists. The work presented here, and taking place in the framework of the hydrobiological research of the INRA, represents the results of three

Phylogenetic Systematics, Biogeography, and Ecology of the Electric Fish Genus Brachyhypopomus (Ostariophysi: Gymnotiformes)

open access: yesPLoS ONE, 2016
A species-level phylogenetic reconstruction of the Neotropical bluntnose knifefish genus Brachyhypopomus (Gymnotiformes, Hypopomidae) is presented, based on 60 morphological characters, approximately 1100 base pairs of the mitochondrial cytb gene, and ...

Dynamic Micromechanical Characterization of 3D Printed Bone In Vitro Models Manufactured via Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a novel approach to designing and fabricating high‐porosity 3D‐printed scaffolds using a customized resin. Scaffold geometry, cellular interactions, and mechanical properties are analyzed to demonstrate these engineered bone models.

Review of Magnetic Shark Deterrents: Hypothetical Mechanisms and Evidence for Selectivity

open access: yes, 2014
Several papers published since 2006 describe effects of magnetic fields on elasmobranchs and assess their utility in reducing negative interactions between sharks and humans, including bycatch reduction.
