M, L and T dwarfs in the J-PLUS Survey
, 2017 A deep and wide sky survey such as J-PLUS will image thousands of M dwarfs, hundreds of L dwarfs, and tens of T dwarfs. M dwarfs are now ideal targets for habitable exoplanet searches, L dwarfs are a main contributor to the mass function in the solar ...

DISCOVERY OF 11 NEW T DWARFS IN THE TWO MICRON ALL SKY SURVEY, INCLUDING A POSSIBLE L/T TRANSITION BINARY [PDF]
, 2007 We present the discovery of 11 new T dwarfs, found during the course of a photometric survey for mid-to-late T dwarfs in the 2MASS Point Source Catalog and from a proper-motion-selected sample of ultracool dwarfs in the 2MASS Working Database.

Immune Checkpoint Inhibitor–Related Myositis and Associated Triad Overlap Syndrome
Arthritis Care &Research, EarlyView.Objective Immune checkpoint inhibitor (ICI) myositis is a rare but a highly morbid condition, particularly with the ICI myositis triad syndrome of myositis, myocarditis, and myasthenia gravis. We report the clinical characteristics of ICI myositis and all‐cause mortality in these patients.

Exploration of the Near-infrared Colors of Cold Y Dwarfs from the Ground and Space
The Astrophysical JournalThe James Webb Space Telescope (JWST) has provided critical mid-infrared data for cold brown dwarfs. It has also provided low-resolution near-infrared spectra, and for faint sources these are the first spectra at these wavelengths.

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Constraining the Distribution of L and T Dwarfs in the Galaxy
The Astrophysical Journal, 2005 We estimate the thin disk scale height of the Galactic population of L- & T-dwarfs based on star counts from 15 deep parallel fields from the Hubble Space Telescope. From these observations, we have identified 28 candidate L- & T- dwarfs based on their (i'-z') color and morphology.

Gray Spectral Variability in Three Brown Dwarfs Observed by HST/WFC3 Time-series Observations
The Astrophysical JournalThe L/T transition is a critical evolutionary stage for brown dwarfs and self-luminous giant planets. L/T transition brown dwarfs are more likely to be spectroscopically variable, and their high-amplitude variability probes distributions in their clouds ...

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights
Advanced Functional Materials, EarlyView.This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.
