Discovery of Seven Cold and Distant Brown Dwarfs with JWST RUBIES

The Astronomical Journal
We report near-infrared spectral model fits to seven distant L- and T-type dwarfs observed with the JWST Near Infrared Spectrograph as part of the Red Unknowns: Bright Infrared Extragalactic Survey (RUBIES).

AI‐Enhanced Laser Manufacturing: A Social Life Cycle Perspective From the White Goods Industry

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable manufacturing transitions require companies to demonstrate not only environmental and economic benefits, but also measurable advances in corporate social responsibility (CSR). Therefore, we propose using a guideline‐based Social Life Cycle Assessment (S‐LCA) aligned with UNEP (2020) and ISO 14075 (2024) to evaluate the social ...

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

Contributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

A Volume-limited Sample of Ultracool Dwarfs. II. The Substellar Age and Mass Functions in the Solar Neighborhood

The Astrophysical Journal
We present the most precise constraints to date for the mass and age distributions of single ultracool dwarfs in the solar neighborhood, based on an updated volume-limited sample of 504 L, T, and Y dwarfs within 25 pc.

On the coronae of rapidly rotating stars. III - an improved coronal rotation-activity relation in late type dwarfs

The Astrophysical Journal, 1982
While it has previously been claimed that X-ray luminosity, or surface flux, varies as a power of the rotational velocity in G dwarfs, it is demonstrated that a single power law does not provide an acceptable fit to all the data. The data are describable by a power law, with a break in slope near a 12-day period which occurs at the same rotational ...

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

The Massive and Quiescent Elliptical Host Galaxy of the Repeating Fast Radio Burst FRB 20240209A

The Astrophysical Journal Letters
The discovery and localization of FRB 20240209A by the Canadian Hydrogen Intensity Mapping Fast Radio Burst (CHIME/FRB) experiment marks the first repeating FRB localized with the CHIME/FRB Outriggers and adds to the small sample of repeating FRBs with ...

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

EcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Tidal Synchronization of Binaries in Pleiades

The Astrophysical Journal
Tidal interactions in close binaries play a key role in the long-term rotational and orbital evolution. The distributions of circularization across open clusters (OCs) place strong observational constraints on tidal dissipation in binaries.
