Multi-Task Learning for Real-Time Atmospheric Duct Characterization in Wireless Propagation Channels

IEEE Open Journal of Antennas and Propagation
Atmospheric ducting significantly influences radio wave propagation, especially in maritime and desert regions. Rapid refractive-index variations critically affect signal propagation, especially for next-generation systems operating in the sub-6 GHz and ...

A Simple Two-Dimensional Ray-Tracing Visual Tool in the Complex Tropospheric Environment

Atmosphere, 2017
This paper introduces a simple two-dimensional ray-tracing visual tool, Ray-VT, for simulating propagations in the tropospheric environment. It is capable of tracing ray paths through range-dependent refractive conditions as well as arbitrary terrain ...

Discovery and Optimization of AMT‐676, a CDH17‐Targeting ADC for the Treatment of Advanced Gastrointestinal Cancers

Advanced Science, EarlyView.
AMT‐676 is a novel antibody‐drug conjugate targeting CDH17, an adhesion molecule uniquely exposed on gastrointestinal tumor surfaces. Engineered with an optimized exatecan payload, it demonstrates profound tumor regression and a robust bystander effect across diverse preclinical models.

Atmospheric ducts can transport sound in two directions [PDF]

Eos, Transactions American Geophysical Union, 2014
When conditions are right, temperature gradients and fast jets of wind can help to establish atmospheric ducts—pathways in the atmosphere that promote the propagation of low‐frequency acoustic waves (infrasound)—across long distances. Atmospheric ducts are part of the basis behind over‐the‐horizon radar, the source of some particularly clear mirages ...

SIRT5‐Mediated Desuccinylation of ACAA2 Protects Against Calcium Oxalate‐Induced Kidney Injury by Regulating Fatty Acid Oxidation to Suppress Mitochondrial Oxidative Injury and Ferroptosis

Advanced Science, EarlyView.
The SIRT5/ACAA2 axis maintains lipid metabolic homeostasis in RTECs by promoting ACAA2 desuccinylation and preserving its stability and enzymatic activity, thereby sustaining FAO and limiting PUFA and PUFA‐containing phospholipid accumulation. Under CaOx stress, SIRT5 downregulation impairs FAO, promotes oxidative stress and ferroptosis, and enhances ...

Coastal effects on radar propagation in atmospheric ducting conditions

Meteorological Applications, 2006
AbstractTwo models were used to assess the effects of coastal characteristics on radar propagation in ducting conditions in the Persian Gulf. The NCAR/Penn State MM5 model simulated atmospheric conditions at a 5‐km horizontal spatial and hourly temporal resolution on a day on which observations of ducts existed.

Morphology of the patent arterial duct : features relevant to treatment [PDF]

, 2008
Patent ductus arteriosus (PDA), one of the most common congenital heart defects, is an abnormal persistence of a patent lumen in the arterial duct due to an arrest of the natural process of closure after it has served its function as a vital channel ...

Bio‐Memristor Based on Clinical Bile Samples: A Proof‐of‐Concept Pilot Study for Detection of Gallbladder Cancer

Advanced Science, EarlyView.
In this work, we present a bile‐based memristor hardware framework that enables direct, label‐free identification of cholelithiasis and gallbladder cancer at the device level. The Ag/bile/FTO memristor features stable resistive switching and disease‐specific electrical responses, providing a conceptual foundation for circuits and an integrated ERCP ...

Exploring Marine Atmospheric Ducts: Current Sensing and Emerging Trends

Remote Sensing
Tropospheric refraction significantly impacts the propagation of ultrashort- and microwave-frequency radio waves over marine environments. Atmospheric ducting, the most common super-refractive structure, allows radio waves to travel over the horizon ...
