Chinese Registry on Transjugular Intrahepatic Portosystemic Shunts (CN‐TIPS): Protocol for a Registry‐Based, Prospective Prognostic Study

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
CN‐TIPS is a nationwide, multicenter prospective registry that will enroll 10,000 adults with portal hypertension undergoing transjugular intrahepatic portosystemic shunt in China, integrating perioperative clinical and hemodynamic metrics with standardized imaging (including computational modeling in a dedicated subcohort) and multi‐omics biospecimens,

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Hydroxyl‐Terminated Polybutadiene‐Based Molding Powders as an Alternative Route for Manufacturing Pressed Polymer‐Bonded Explosives

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Estimating Rain‐Specific Attenuation at Extremely High Frequencies From Disdrometer Measurements at Various Climate Zones in the US

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity
