Transient Interference Suppression Algorithm Based on Time Frequency Sparse Prior for Skywave OTHR

Leida xuebao
The target detection performance of skywave Over-the-Horizon Radar (OTHR) often struggles with transient interference. To address this issue, we have developed a transient interference suppression algorithm that uses Time Frequency Sparsity Prior (TFSP).

A unified formulation for home healthcare routing and scheduling problems

International Transactions in Operational Research, EarlyView.
Abstract Home Healthcare is an essential component of healthcare systems, where caregivers visit patients' homes to deliver services. While presenting advantages with respect to institutional care, such as being cost‐effective and alleviating family burdens, it presents challenges in scheduling and routing caregivers efficiently.

Modelling compressive loading in large‐bodied mammals reveals distinct biomechanical strategies in proboscidean humeri

Journal of Anatomy, EarlyView.
Graviportal proboscideans differ in limb morphology, adopting slender or more robust long bone morphotypes. Finite element analyses (FEA) on extant and extinct taxa reveal functional differences between morphotypes, with robust humeri exhibiting lower peak stress under neutral and off‐axis loading.

Robust Altitude Estimation For Over-The-Horizon Radar Using A

, 2007
In previous work, a matched-field estimate of aircraft altitude from multiple over-the-horizon radar dwells was presented. This approach exploits the altitude dependence of direct and surface reflected returns off the aircraft and the relative phase ...

AI Alignment Versus AI Ethical Treatment: 10 Challenges

Analytic Philosophy, EarlyView.
ABSTRACT A morally acceptable course of AI development should avoid two dangers: creating unaligned AI systems that pose a threat to humanity and mistreating AI systems that merit moral consideration in their own right. This paper argues these two dangers interact and that if we create AI systems that merit moral consideration, simultaneously avoiding ...

Elevation bias due to penetration of spaceborne radar signal on Grosser Aletschgletscher, Switzerland

Journal of Glaciology
Digital elevation models (DEMs) from the spaceborne interferometric radar mission TanDEM-X hold a large potential for glacier change assessments. However, a bias is potentially introduced through the penetration of the X-band signal into snow and firn ...

Long‐term outcomes of lateral sinus floor elevation: A machine‐learning analysis, systematic review, and meta‐analysis of predictive factors

Periodontology 2000, EarlyView.
Abstract Objectives To quantify long‐term (≥ 5 years) implant survival after lateral sinus floor elevation (LSFE) and to identify clinical predictors of long‐term survival using conventional and machine‐learning meta‐analytic techniques. Methods A systematic search was conducted through MEDLINE, Embase and Scopus.

Association of tracks from over the horizon radar

, 1998
In Over-The-Horizon Radar (OTHR), multiple ionospheric layers cause several tracks per target to be observed. This effect causes ambiguities in target identification and track coordinate registration.

Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

A New Perspective on the Scattering Mechanism of S-Band Weather Radar Clear-Air Echoes Based on Communication Models

Remote Sensing
Clear-air echo studies are usually based on isotropic turbulence theory. But the theory has been considered incomplete by modern turbulence theory. The intermittence of turbulence can reveal obvious shortcomings in the existing studies of clear-air ...
