Boundary‐Dependent Sleep–Wake Dysregulation in Idiopathic Hypersomnia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...

Investigating the Behavioral Biases of Individual investors’ Decision using Bailard, Biehl and Kaiser Five-Way Model [PDF]

راهبرد مدیریت مالی
Behavioral biases are systematic and predictable errors that can occur in making financial decisions. Bailard, Biehl and Kaiser five-way model is one of the general models for understanding and identifying behavioral biases. Based on this, the purpose of

Kilometer‐scale Kaiser effect identified in Krafla volcano, Iceland [PDF]

Geophysical Research Letters, 2015
AbstractThe Krafla rifting episode in 1975–1984, consisted of around 20 inflation‐deflation events within the Krafla caldera, where magma accumulated during inflation periods and was intruded into the transecting fissure swarm during brief periods of deflation. We reanalyze geodetic and seismic data from the rifting episode and perform a time‐dependent

Multiplexed Detection of Respiratory Viruses Using Surface Plasmon Resonance Spectroscopy With Ultrathin Carbon Nanomembranes

Advanced Healthcare Materials, EarlyView.
An ultrathin azide‐functionalized carbon nanomembrane (N3‐CNM) provides a versatile biointerface for antibody immobilization on gold SPR sensors. Integrated with a multichannel SPR platform, the functionalized surface enables label‐free, simultaneous detection of SARS‐CoV‐2, Influenza A, and RSV antigens, demonstrating the potential of CNM‐based ...

Highly Conductive and Transparent Coatings via Low‐Temperature Hydroiodic Acid Vapor Treatment of Oxo‐Graphene Thin Films

Advanced Materials Technologies, EarlyView.
The double self‐assembly (DSA) method applied to oxo‐graphene (oxo‐G) flakes followed by hydroiodic acid (HI) vapor treatment and low‐temperature annealing yields highly conductive, optically transparent thin films with the potential for applications in electronic and optoelectronic devices.

Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI

Advanced Science, EarlyView.
ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

ZrCo3B2 and HfCo3B2 Electrodes Go on Stage for Oxygen Evolution Reaction

Advanced Science, EarlyView.
The intermetallic compounds ZrCo3B2 and HfCo3B2 with distinctive chemical bonding features are excellent OER precursors, restructuring into OER‐active electrocatalysts delivering significantly high OER activities compared to the elemental Co, which is obvious from their lower onset potentials and increased obtained current densities.
