Chemical Nature of Hydrothermal Fluids Generated by Serpentinization and Carbonation of Komatiite: Implications for H2‐Rich Hydrothermal System and Ocean Chemistry in the Early Earth

open access: yesGeochemistry, Geophysics, Geosystems, 2021
H2‐rich ultramafic‐hosted hydrothermal systems are considered to be important places for the origin and early evolution of life. In this study, we conducted two hydrothermal serpentinization/carbonation experiments involving synthetic komatiite under CO2‐

A new approach of high speed cutting modelling: SPH method [PDF]

open access: yes, 2006
The purpose of this study is to introduce a new approach of high speed cutting numerical modelling. A lagrangian Smoothed Particle Hydrodynamics (SPH) based model is carried out using the Ls-Dyna software.

Body Image Disorders: Comparison between Unilateral Hemisphere Damage and Schizophrenia

open access: yesBehavioural Neurology, 1989
The records of a consecutive series of 100 schizophrenics were examined for any mention of body image disorders. These were present in 45 patients, the most common varieties being anomalous bodily experiences.

Integration of Industrially-Oriented Human-Robot Speech Communication and Vision-Based Object Recognition

open access: yesSensors, 2020
This paper presents a novel method for integration of industrially-oriented human-robot speech communication and vision-based object recognition. Such integration is necessary to provide context for task-oriented voice commands.

Structure and Properties of Arc Ion Plating Deposited AlCrSiN Coatings Controlled by Pulsed Bias Voltage

open access: yesMetals, 2023
AlCrSiN coatings are promising protective candidates for cutting and forming tools. During the coating deposition process, the microstructure and properties of the coatings were dramatically affected by bias voltages.

An Innovative Experimental Study of Corner Radius Effect on Cutting Forces [PDF]

open access: yes, 2014
The cutting forces are often modelled using edge discretisation methodology. In finish turning, due to the smaller corner radii, the use of a local cutting force model identified from orthogonal cutting tests poses a significant challenge. In this paper,

Cellular Responses of Human Lymphatic Endothelial Cells to Carbon Nanomaterials

open access: yesNanomaterials, 2020
One of the greatest challenges to overcome in the pursuit of the medical application of carbon nanomaterials (CNMs) is safety. Particularly, when considering the use of CNMs in drug delivery systems (DDSs), evaluation of safety at the accumulation site ...

Genomic insights into phage-host interaction in the deep-sea chemolithoautotrophic Campylobacterota, Nitratiruptor

open access: yesISME Communications, 2022
The genus Nitratiruptor represents one of the most numerically abundant chemolithoautotrophic Campylobacterota populations in the mixing zones of habitats between hydrothermal fluids and ambient seawater in deep-sea hydrothermal environments. We isolated

Testing uniformity on high-dimensional spheres against monotone rotationally symmetric alternatives

open access: yes, 2016
We consider the problem of testing uniformity on high-dimensional unit spheres. We are primarily interested in non-null issues. We show that rotationally symmetric alternatives lead to two Local Asymptotic Normality (LAN) structures. The first one is for

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.
