Early CN Outgassing and Production Rates of C/2024 E1 (Wierzchos) at 4 au

open access: yesThe Planetary Science Journal
The study of cometary activity at large heliocentric distances provides insights into the volatile release processes in the outer solar system. Early models predicted cometary activity was driven primarily by sublimation of water and therefore would ...

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Machine Learning Methods to Predict the Length of Stay for Acute Stroke: A Scoping Review and Meta‐Analysis

open access: yesHealth Care Science, EarlyView.
Current machine learning models for predicting the length of stay for acute stroke lack clinical utility and reliability. This scoping review highlights areas for improvement to develop more robust, interpretable, generalizable, and clinically actionable models that optimize personalized clinical pathways and support precise decision‐making for stroke ...

Inferring the CO2 Abundance in Comet 45P/Honda-Mrkos-Pajdušáková from [O i] Observations: Implications for the Source of Icy Grains in Cometary Comae

open access: yesThe Planetary Science Journal
The study of cometary composition is important for understanding our solar system's early evolutionary processes. Carbon dioxide (CO _2 ) is a common hypervolatile in comets that can drive activity but is more difficult to study than other hypervolatiles

COMAE: COMprehensive Attribute Exploration for Zero-shot Hashing

open access: yes
Zero-shot hashing (ZSH) has shown excellent success owing to its efficiency and generalization in large-scale retrieval scenarios. While considerable success has been achieved, there still exist urgent limitations.

Fundamental data for contact binaries: RZ Comae, RZ Tauri, and AW UMa

open access: yes, 1972
Differential corrections analyses of three W UMa type binaries show that RZ Tau and AW UMa have common envelopes and the relatively small gravity darkening predicted by Lucy, while RZ Comae seems to have a larger gravity effect and is only marginally in ...

VERITAS Discovery of >200GeV Gamma-ray Emission from the Intermediate-frequency-peaked BL Lac Object W Comae

open access: yes, 2008
We report the detection of very high-energy gamma-ray emission from the intermediate-frequency-peaked BL Lacertae object W Comae (z=0.102) by VERITAS. The source was observed between January and April 2008.
