Probabilistic Spectral Reconstruction of Trans-Neptunian Objects from Sparse Photometry: A Framework for Taxonomy, Survey Optimization, and Outlier Detection

The Astronomical Journal
Near-infrared (near-IR) spectroscopy provides critical constraints on the surface composition of trans-Neptunian objects (TNOs), but spectroscopic observations remain limited compared to broadband photometry.

Body‐integrated photonic biosensors: Illuminating the path to active healthcare

FlexMat, EarlyView.
Body‐integrated photonic biosensors are promising tools for active healthcare. These optical devices can be worn, implanted, or swallowed to monitor health signals continuously. This review introduces key sensing modalities, including fluorescence, colorimetry, SPR, LSPR, SERS, and light‐modulating materials.

Surface photometry of early-type galaxies in rich clusters [PDF]

, 1998
This thesis investigates the morphology of early-type galaxies in two rich clusters using 2D surface photometry. In particular, the amount of light in the 'disk' component is focussed upon, as the presence of a disk is the main morphological criterion in

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

Postperihelion Cometary Activity on the Outer Main-belt Asteroid 2005 XR132

The Planetary Science Journal
We report comet-like activity on the outer main-belt asteroid 2005 XR _132 discovered by the Lulin One-meter Telescope in early 2021 April. A series of follow-up observations were triggered to characterize the morphology and brightness variation of 2005 ...

Probing the Earliest Phases in the Formation of Massive Galaxies with Simulated HST+JWST Imaging Data from Illustris

The Astrophysical Journal, 2023
We use the Illustris-1 simulation to explore the capabilities of the Hubble Space Telescope (HST) and James Webb Space Telescope (JWST) data to analyze the stellar populations in high-redshift galaxies, taking advantage of the combined depth, spatial ...

Lucy Observations of the DART Impact Event

The Planetary Science Journal
The Lucy LOng Range Reconnaissance Imager (L’LORRI) took 1549 images of the Didymos–Dimorphos binary system, starting 12 hr before the Double Asteroid Redirection Test (DART) impact event on 2022 September 26 and ending 24 hr after it.

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

The FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...
