Advanced Science, EarlyView.An electronics‐free smart scleral lens passively monitors dry eye disease‐related tear biomarkers through colorimetric sensing of chloride, pH, and ocular surface temperature. Smartphone‐assisted image analysis enables quantitative interpretation, providing a simple, non‐invasive strategy for ocular health monitoring without integrated electronics ...

The Merger-driven Formation of Classical Low Surface Brightness Galaxies in Romulus25
The Astrophysical JournalWe use the R omulus 25 cosmological simulation volume to study a large sample of late-type gas-rich galaxies with low central surface brightnesses known as classical low surface brightness (LSB) galaxies and compare them to a mass-matched sample of high ...

Structural properties of faint low-surface-brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We study the structural properties of Low Surface Brightness galaxies (LSB) using a sample of 263 galaxies observed by the Green Bank Telescope (Schneider et al 1992). We perform 2D decompositions of these galaxies in the SDSS $g$, $r$ and $i$ bands using the GALFIT software. Our decomposition reveals that about $60\%$ of these galaxies are bulgeless i.

HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots
Advanced Intelligent Systems, EarlyView.A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

A catalog of low surface brightness galaxies - List II [PDF]
The Astronomical Journal, 1992 A list of galaxies characterized by low surface brightness (LSB) is presented which facilitates the recognition of galaxies with brightnesses close to that of the sky. A total of 198 objects and 140 objects are listed in the primary and secondary catalogs respectively, and LSB galaxies are examined by means of H I redshift distributions.

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT
Astronomische Nachrichten, EarlyView.ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

Ultradeep Imaging of Nearby Dwarf Irregular Galaxies: Stellar Haloes and Disk Structure
The Astronomical JournalWe have examined the stellar structure of 10 nearby, low stellar mass (10 ^6 –6 × 10 ^7 M _⊙ ) dwarf irregular galaxies by fitting ellipses as a function of surface brightness on ultradeep V images. These are compared to far-ultraviolet images as tracers

Beyond Ultra-diffuse Galaxies. I. Mass–Size Outliers among the Satellites of Milky Way Analogs
The Astrophysical Journal, 2023 Large diffuse galaxies are hard to find, but understanding the environments where they live, their numbers, and ultimately their origins, is of intense interest and importance for galaxy formation and evolution. Using Subaru’s Hyper Suprime-Cam Strategic
