Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

Experimental investigation of frost heave in clayey sands: Effects of density and thermal conditions [PDF]

open access: yesE3S Web of Conferences
This study experimentally investigates the effects of soil density and temperature boundary conditions on frost heave behaviour and ice lens formation in saturated specimens composed of a binary sand - kaolin mixture.

The Big Picture: Religion and Global Comparative History

open access: yesJournal of Religious History, EarlyView.
This article considers what a ‘big picture’ approach to global religious history might look like, and in particular the implications of deploying the comparative method across much larger stretches of time and space than historians normally attend to. It will begin by reflecting on the epistemological moods that have hindered this project to date, the ...

Study on the Influence of Chamfer Perforation on Heave and Pitch of a Single Floating Platform

open access: yesPolish Maritime Research, 2023
The aim of this work is to study the influence of chamfered perforation and chamfering on the heave and pitch motion of a single floating wind power platform with an anti-heave device.

Advanced imaging and multi‐omics to characterize cardiomyocyte ageing and its electrocardiographic imprint in PKP2 arrhythmogenic cardiomyopathy

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We used a murine model of cardiomyocyte‐specific conditional knockout of plakophilin 2 (PKP2cKO, middle panel). Using advanced imaging technology, we unveiled distinct hallmarks of premature ageing in PKP2cKO cardiomyocytes, including DNA damage and loss of repressed heterochromatin at the nuclear periphery, and mitochondrial ...

Unsteady high-lift mechanisms from heaving flat plate simulations [PDF]

open access: yesInternational Journal of Heat and Fluid Flow, 2017
Flapping animal flight is often modeled as a combined pitching and heaving motion in order to investigate the unsteady flow structures and resulting forces that could augment the animal's lift and propulsive capabilities. This work isolates the heaving motion of flapping flight in order to numerically investigate the flow physics at a Reynolds number ...

Multi‐objective maritime vessel routing with safety considerations

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 1, Page 337-371, January 2027.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Hydrodynamic Coefficients of Heave Plates, With Application to Wave Energy Conversion [PDF]

open access: yesIEEE Journal of Oceanic Engineering, 2018
Wave energy converters (WECs) often employ submerged heave plates to provide reaction forces at depths below the level of wave motion. Here, two sets of heave plate experiments are described, at varying scale. First, the Oscillator uses a linear actuator to force laboratory scale (30.5-cm diameter) heave plates in sinusoidal motion. Second, the miniWEC

Response of an Infant With Presumed Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) to Ketone Supplementation

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 9, Page 2140-2150, September 2026.
ABSTRACT Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) is an autosomal recessive inborn error of metabolism caused by biallelic pathogenic variants in one of three known genes: ETFA, ETFB, and ETFDH. It can cause multisystem dysfunction, including cardiomyopathy in severe cases.
