Narcolepsy and rapid eye movement sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

Navigating troubled waters: Posthumanist vulnerability and entanglement in Richard Powers's Playground (2024)

Orbis Litterarum, EarlyView.
Abstract Richard Powers's most recent novels to date—The Overstory (2018), Bewilderment (2021), and Playground (2024)—engage with some of the environmental and technological threats that loom over our planet, such as deforestation, species loss, the degradation of the ocean bottom, and the risks associated with the development of generative AI ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Dead time, hard time, and narrative redemption: Delimiting the life proper

The Southern Journal of Philosophy, EarlyView.
Abstract Is every detail of your life a candidate for the meaningful, valuable, or worthwhile? If not, which do you exclude? Thaddeus Metz nominates “dead time”: the nail‐clipping, line‐waiting, traffic‐jam enduring, generally commonplace moments of our life. Dead time, while prevalent, is not remarkable. Metz recommends that we set at least some of it

High‐Resolution Modeling to Quantify CO2 Emissions From an Industrial Point Source

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Orbiting Carbon Observatory‐3 (OCO‐3) provides precise observations of the column‐averaged dry air mole fraction of carbon dioxide (XCO2 ${\text{XCO}}_{2}$) with the ability to target specific areas using the Snapshot Area Maps (SAMs).

Comparative Gas‐Brine Relative Permeability of H2, N2, and CO2 Under Subsurface Storage Conditions

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Gas‐brine relative permeability controls subsurface gas storage, including underground hydrogen and CO2 storage. Here, we measure steady‐state gas‐brine relative permeabilities for H2, N2, and CO2 in a sandstone core at 0.1–6 MPa under identical conditions.

Sensitivity of Double‐Diffusive Mixed Convection in an Enclosure With a Zigzag Bottom Wall and a Torsionally Oscillating Lid Using Hybrid Nanofluid

Engineering Reports, Volume 8, Issue 7, July 2026.
This study investigates the nature of sensitivity of an unsteady double‐diffusive mixed convective analysis in a trapezoidal enclosure featuring a zigzag bottom wall and a torsionally oscillating lid. This cavity is filled by a hybrid nanofluid (Ag‐MgO‐H2O). The cavity also contains internal heat generation.

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

International Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for
