Polish Maritime Research, 2016 One of the fundamental states of the sea surface is its heave. Despite of years of the intense scientific inquiry, no clear understanding of the influence of this aspect on the dynamics of the sea environment has emerged.

The Journal of Physiology, EarlyView.Abstract figure legend Fetal growth restriction (FGR) is a common pregnancy complication associated with long‐term neurodevelopmental impairments. Using the reduced uterine perfusion pressure (RUPP) rat model of placental insufficiency‐induced FGR, this study demonstrates that FGR leads to persistent anatomical, histological and behavioural ...

The topological strong spatial mixing property and new conditions for pressure approximation [PDF]
, 2014 In the context of stationary $\mathbb{Z}^d$ nearest-neighbour Gibbs measures $\mu$ satisfying strong spatial mixing, we present a new combinatorial condition (the topological strong spatial mixing property (TSSM)) on the support of $\mu$ sufficient for ...

, 2018 Autonomous underwater vehicles (AUVs) are being tasked with increasingly complex missions. The acoustic communications required for AUVs are, by the nature of the medium, low bandwidth while adverse environmental conditions underwater often mean they are

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2500-2507, May 2026.ABSTRACT Purpose To present a method for quantifying dissolved 129Xe spectroscopy using singular value decomposition (SVD) and a dynamic red blood cell (RBC)/membrane ratio as a biomarker of disease. Methods A spectroscopic sequence was performed in 45 subjects (27 healthy, 12 dyspnea of unknown origin [DUO], and 6 pulmonary hypertension [PH ...

Ultrasonic vocalization of pup and adult fat-tailed gerbils (Pachyuromys duprasi).
PLoS ONE, 2019 Ultrasonic vocalizations (USVs) of laboratory rodents indicate animal emotional arousal and may serve as models of human disorders. We analysed spectrographically USV calls of pup and adult fat-tailed gerbils Pachyuromys duprasi during 420-s tests ...

Split Fermions in Extra Dimensions and CP Violation [PDF]
, 2000 We discuss CP violation in the quark sector within a novel approach to the Yukawa puzzle proposed by Arkani-Hamed and Schmaltz, where Yukawa hierarchies result from localising the Standard Model quark field wave-functions, at different positions (in the ...

IFAC Proceedings Volumes, 2010 Abstract The protection of civilian harbours has received an increasing interest after September 11th. One of the areas currently under major investigation is the use of a team of Unmanned Surface Vehicles (USVs), which could be exploited for patrolling purposes and to investigate suspect situations, increasing the effectiveness of the harbor ...

A DDPG-Based USV Path-Planning Algorithm
Applied Sciences, 2023 Path planning is crucial in the automatic navigation of USVs (unmanned underwater vehicles), which directly affects the operational efficiency and safety of USVs. In this paper, we propose a path-planning algorithm based on DDPG (Deep Deterministic Policy Gradient) and make a detailed comparison with the traditional A-Star algorithm and the recent ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR
River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.
