Transmitter and ion channel profiles of saccadic omnipause neurons and cholinergic non-omnipause neurons in human nucleus raphe interpositus [PDF]

open access: yesFrontiers in Neuroanatomy
BackgroundOmnipause neurons (OPN) are glycinergic neurons that tonically inhibit burst neurons between saccades. In primates, OPNs are located bilaterally around the midline at the level of the traversing rootlets of the abducens nerve in the pontine ...

Vertical Distribution of Rip Currents Generated by Intersecting Waves in a Sandbar–Groin Systems

open access: yesJournal of Marine Science and Engineering
To analyze the impacts of groins, sandbars, and channels on the three-dimensional features of rip currents, we conducted experimental investigations on the vertical distribution of rip currents under intersecting waves along barred beaches with channels.

Development and evaluation of a rip current forecasting system for channel-type rip currents on a low-energy headland beach

open access: yesGeomatics, Natural Hazards & Risk
A 34-day field observation was conducted on a headland beach in South China with a typical channel rip current system. The Delft3D model was applied to reproduce hydrodynamic conditions and extract rip currents, while a Generalized Additive Model (GAM ...

Beachgoers' ability to identify rip currents at a beach in situ [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2021
Rip currents (“rips”) are the leading cause of drowning on surf beaches worldwide. A major contributing factor is that many beachgoers are unable to identify rip currents. Previous research has attempted to quantify beachgoers' rip identification ability

Flow Characteristics of the Rip Current System near a Shore-Normal Structure with Regular Waves

open access: yesJournal of Marine Science and Engineering, 2023
Rip currents are the strong narrow seaward current produced by waves breaking on the coast. Of the many types of rip currents, the present study investigates, experimentally and numerically, the rip current system produced by the wave reflection on a ...

How to Shut Down Transcription in Archaea during Virus Infection

open access: yesMicroorganisms, 2022
Multisubunit RNA polymerases (RNAPs) carry out transcription in all domains of life; during virus infection, RNAPs are targeted by transcription factors encoded by either the cell or the virus, resulting in the global repression of transcription with ...

Rip currents by intersecting wave on barred beach with rip channel

open access: yesShui kexue jinzhan, 2019
The study of rip currents by intersecting waves is helpful to the comprehensive study of disaster mechanisms and risk assessment. To better understand the characteristics of rip currents controlled by hydrodynamic forcing and longshore topographical ...

Sodium channel β1 subunits participate in regulated intramembrane proteolysis-excitation coupling

open access: yesJCI Insight, 2021
Loss-of-function (LOF) variants in SCN1B, encoding voltage-gated sodium channel β1 subunits, are linked to human diseases with high risk of sudden death, including developmental and epileptic encephalopathy and cardiac arrhythmia.

Environmental controls on surf zone injuries on high-energy beaches [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2019
The two primary causes of surf zone injuries (SZIs) worldwide, including fatal drowning and severe spinal injuries, are rip currents (rips) and shore-break waves. SZIs also result from surfing and bodyboarding activity.
