Evaluation of the Effectiveness of Sonification for Time-series Data Exploration

The Astronomical Journal
Astronomy is a discipline primarily reliant on visual data. However, alternative data representation techniques are being explored, in particular “sonification,” namely, the representation of data into sound.

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers

Advanced Functional Materials, EarlyView.
Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Infrared Nanocrystals for Space Application: Hardness to Irradiations

Advanced Functional Materials, EarlyView.
This article investigates infrared HgTe nanocrystals under X‐ray and ion irradiation, revealing remarkable radiation hardness. It uncovers distinct degradation mechanisms and shows that the nanomaterial outperforms integrated electronics. The results position colloidal nanocrystals as promising candidates for resilient space and harsh‐environment ...

Precise Distance Measurement for a Near-Earth Asteroid by the Refined Rotational Reflex Velocity Method

The Astronomical Journal, 2023
The rotational reflex velocity (RRV) method was proposed by Heinze and Metchev in 2015 and was used to measure the distances of main-belt asteroids (MBAs). Later, Lin et al. generalized this method using spherical astronomy in 2016.

A search for periodicity in the light curves of selected blazars

, 2005
We present an analysis of multifrequency light curves of the sources 2223-052 (3C 446), 2230+114 (CTA 102), and 2251+158 (3C 454.3), which had shown evidence of quasi-periodic activity.

Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Spatiotemporal Characterization of Cassiopeia A

The Astrophysical Journal, 2023
Analyzing the X-ray data of supernova remnants (SNRs) is among the most challenging tasks in current X-ray astronomy because SNRs are both spatially extended and variable over time. We developed the strategy to track the time-series properties of all the

Introduction to papers on astrostatistics

, 2009
We are pleased to present a Special Section on Statistics and Astronomy in this issue of the The Annals of Applied Statistics. Astronomy is an observational rather than experimental science; as a result, astronomical data sets both small and large ...
