Potential Chromospheric Evaporation in the M Dwarf’s Flare Triggered by Einstein Probe Mission

The Astronomical Journal
Although flares from late-type main-sequence stars have been frequently detected in the multiwavelength, the associated dynamical process has been rarely reported so far.

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 Radio Flaring, Chromospherically Inactive K Dwarf

The Astrophysical Journal
We report on an unusual radio source (J180526−292953), initially identified as a steep spectrum, polarized point source toward the Galactic bulge and found to coincide with the nearby K dwarf HD 317101A.

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.

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).

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.

State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

Environmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

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.

Environmental Policy Without Implementation? A Review of Factors Contributing to Implementation Gaps in Low‐ and Middle‐Income Countries

Environmental Policy and Governance, EarlyView.
ABSTRACT The sound formation of robust environmental policies is increasingly important for low‐ and middle‐income countries (LMICs) to achieve their national objectives and international commitments. However, policy implementation can be complex, and environmental policies may not be prioritised given other critical socio‐economic development issues ...
