A reach-integrated hydraulic modelling approach for large-scale and real-time inundation mapping [PDF]

open access: yesGeoscientific Model Development
Flooding is one of the world's most common and costly natural hazards, inflicting billions in damages each year. However, current hydraulic models to support flood mapping are not well suited for large-scale applications or frequent updates, either due ...

Heron Visualisation Engine. Visualisation and dissemination of semantic cultural heritage data [PDF]

open access: yes, 2017
Over the past two decades, there has been a proliferation of software to create great 3D models of archaeological sites and objects, and there has been plenty of thought and discussion on data models for finds. The results of those efforts have been made

A Precessing Numerical Relativity Waveform Surrogate Model for Binary Black Holes: A Gaussian Process Regression Approach [PDF]

open access: yes, 2020
Gravitational wave astrophysics relies heavily on the use of matched filtering both to detect signals in noisy data from detectors, and to perform parameter estimation on those signals.

INVESTIGATING THE PERFORMANCE OF A HANDHELD MOBILE MAPPING SYSTEM IN DIFFERENT OUTDOOR SCENARIOS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
In recent years, portable Mobile Mapping Systems (MMSs) are emerging as valuable survey instruments for fast and efficient mapping of both internal and external environments. The aim of this work is to assess the performance of a commercial handheld MMS,

Neutral Pion Decay Width in a Hot and Dense Medium [PDF]

open access: yes, 2003
We study the behavior of the $\pi^0$ width as a function of temperature and density. We provide simple expressions for the neutral pion width in a hot and dense medium based on a renormalized version of the microscopic Nambu Jona Lasinio model.

A study on out-of-field leakage of an accelerator-based neutron beam for boron neutron capture therapy

open access: yesFrontiers in Oncology
More and more accelerator-based boron neutron capture therapy (AB-BNCT) facilities are under the construction or commissioning stage, and the neutron beam characteristic measurements at each facility will start soon.

A Look at the Generalized Heron Problem through the Lens of Majorization-Minimization

open access: yes, 2012
In a recent issue of this journal, Mordukhovich et al.\ pose and solve an interesting non-differentiable generalization of the Heron problem in the framework of modern convex analysis.

Log-concavity of characteristic polynomials and the Bergman fan of matroids [PDF]

open access: yes, 2012
In a recent paper, the first author proved the log-concavity of the coefficients of the characteristic polynomial of a matroid realizable over a field of characteristic 0, answering a long-standing conjecture of Read in graph theory.

Helminth communities of herons (Aves: Ardeidae) in southern Italy [PDF]

open access: yes, 2016
The helminth communities of nine species of herons from southern Italy were studied and compared. Of 24 taxa found including seven digeneans, seven nematodes, six cestodes and four acanthocephalans, only five taxa were found in more than one heron ...

Promising benefits of six-month Phaeodactylum tricornutum microalgae supplementation on cognitive function and inflammation in healthy older adults with age-associated memory impairment

open access: yesFrontiers in Aging
IntroductionAging is often associated with cognitive decline and memory impairment, with several factors including inflammatory cytokines and oxidative stress markers implicated in this natural process.
