Beyond the breeding grounds: identifying post‐breeding staging areas, corridors and ecological niche of the Lesser Kestrel

Ibis, EarlyView.
The post‐breeding period is a critical yet overlooked phase in the annual cycle of migratory birds, where individuals must resolve competing bioenergetic trade‐offs between recovery from breeding, moult and migratory fuelling. Using GPS data from 54 adult Lesser Kestrels Falco naumanni tracked across Spain, we analysed 76 post‐breeding tracks to ...

LPI Sequences Optimization Method against Summation Detector Based on FFT Filter Bank

Remote Sensing
Waveform design is a crucial factor in electronic surveillance (ES) systems. In this paper, we introduce an algorithm that designs a low probability of intercept (LPI) radar waveform. Our approach directly minimizes the detection probability of summation

A NOVEL DWELLING TIME DESIGN METHOD FOR LOW PROBABILITY OF INTERCEPT IN A COMPLEX RADAR NETWORK

, 2015
To achieve the important tactical requirement of low probability of intercept (LPI) in the complex radar net-work, dynamically controlling the emission of the radars is very necessary.

Dynamic Trust Formation in AI‐Enabled Automation: A Longitudinal Case Study of an Advanced Driver Assistance System

Information Systems Journal, EarlyView.
ABSTRACT Artificial intelligence (AI)–enabled automation is often utilised in systems that perform human tasks. While useful, these technologies pose a risk of adverse consequences in the case of AI failures as they operate in open environments, learn and are subject to continuous updates.

Long‐term periodontal and peri‐implant tissue stability under supportive therapy

Periodontology 2000, EarlyView.
Abstract Background Supportive periodontal and peri‐implant maintenance therapy is strongly associated with improved long‐term retention and stability of natural teeth and dental implants. Lack of regular professional follow‐up after initial therapy is a major risk factor for disease recurrence and tooth or implant loss.

Antenna Array Beamforming for Low Probability of Intercept Radars [PDF]

, 2013
A radar system's focus on low probability of intercept (LPI) performance has become increasingly important as systems designed for electronic support measures (ESM) and electronic counter measures (ECM) continue to become more prevalent.

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 ...

Introduction to Noise Radar and Its Waveforms

Sensors, 2020
In the system-level design for both conventional radars and noise radars, a fundamental element is the use of waveforms suited to the particular application. In the military arena, low probability of intercept (LPI) and of exploitation (LPE) by the enemy
