The use of multibeam sonar mapping techniques to refine population estimates of the endangered white abalone (Haliotis sorenseni) [PDF]

, 2006
Multibeam sonar mapping techniques provide detailed benthic habitat information that can be combined with the data on species-specific habitat preferences to provide highly accurate calculations of populations in a particular area. The amount of suitable

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Local Angler Knowledge Reveals Declines in Fishing Quality for Black Bass in Lakes of Eastern Ontario

Fisheries Management and Ecology, EarlyView.
ABSTRACT Local ecological knowledge can be useful to assess data‐limited fisheries such as the Ontario Black Bass (Micropterus spp.) recreational fishery. We surveyed local anglers using the Life History Calendar approach to determine if there were perceived changes in fishing quality for Black Bass in eastern Ontario across different time periods. For

Enhancing underwater target detection: Fusion of spatio‐temporal incompletely‐aligned AIS and sonar information via DTW and multi‐head attention mechanism

IET Radar, Sonar & Navigation
In the field of underwater target detection, the passive sonar is an important means of long‐distance target detection. The sonar detection information typically includes both surface and underwater targets, whereas it is a great challenge on effectively

Smartphone language and resting‐state EEG indicators of self‐focused attention prospectively predict major depressive disorder risk in adolescents

Journal of Child Psychology and Psychiatry, EarlyView.
Background Central to major depressive disorder (MDD) onset and maintenance is maladaptive self‐focused attention, which can be reliably indexed by greater: (a) usage of first‐person singular pronouns (e.g., I) in natural language and (b) alpha oscillations in resting‐state EEG.

Sonar-Based Simultaneous Localization and Mapping Using the Semi-Direct Method

Journal of Marine Science and Engineering
The SLAM problem is a common challenge faced by ROVs working underwater, with the key issue being the accurate estimation of pose. In this work, we make full use of the positional information of point clouds and the surrounding pixel data.

A feynman path integral representation for elastic wave scattering by anisotropic weakly perturbations

, 2012
We write a space-time Feynman path integral representation for scattered elastic wave fields from a weakly compact supported anisotropic non-homogeneity.Replacement by a new version where We (I!) propose a new tomographic inversion methodology based ...

Delphi consensus: First‐line use of biologics and small molecules in hidradenitis suppurativa

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This Delphi Consensus study identified upgrade criteria for the use of biologics and small molecules as first‐line therapy in hidradenitis suppurativa (HS). European HS experts evaluated 16 clinical scenarios, voting on eligibility for therapy escalation.
