The Smearing of Quasi‐Particles: Signatures in the Entanglement Entropy of Excited Many‐Particle Systems

open access: yesAdvanced Quantum Technologies, EarlyView.
Entanglement reveals hidden structure in quantum matter. We explore how quasi‐particles shape the crossover from area‐law to volume‐law entanglement, using models from spinless fermions to SYK. Our results show a striking linear growth of entanglement with energy, explained as a hallmark of quasi‐particles, offering new insight into the entanglement ...

Strategies for Embedding Research Data Management Through Effective Communication

open access: yesData
Effective research data management (RDM) is essential for ensuring research integrity, reproducibility, and compliance with FAIR principles. Despite the development of comprehensive RDM frameworks, many institutions still struggle to ensure widespread ...

Barriers and opportunities for robust decision making approaches to support climate change adaptation in the developing world

open access: yesClimate Risk Management, 2016
Climate change adaptation is unavoidable, particularly in developing countries where the adaptation deficit is often larger than in developed countries.

Factors influencing the nature of client complaint behaviour in the aftermath of adverse events

open access: yesVeterinary Record, Volume 196, Issue 6, 15/22 March 2025.
Abstract Background Negative veterinary client complaint behaviour poses wellbeing and reputational risks. Adverse events are one source of complaint. Identifying factors that influence adverse event‐related complaint behaviour is key to mitigating detrimental consequences and harnessing information that can be used to improve service quality, patient ...

Characterization of the biosynthetic gene cluster of the polyene macrolide antibiotic reedsmycins from a marine-derived Streptomyces strain

open access: yesMicrobial Cell Factories, 2018
Background Polyene antibiotics are important as antifungal medicines albeit with serious side effects such as nephrotoxicity. Reedsmycin (RDM) A (1), produced by marine-derived Streptomyces youssoufiensis OUC6819, is a non-glycosylated polyene macrolide ...

Signal‐to‐noise and spatial resolution in in‐line imaging. 3. Optimization using a simple model

open access: yesJournal of Synchrotron Radiation, EarlyView.
Geometrical magnification and X‐ray energy are optimized with respect to spatial resolution, contrast, noise, radiation dose and other image quality characteristics. The optimization is performed using a simple theoretical model of a homogeneous edge feature embedded in a bulk uniform sample, and the resulting generic analytical expressions for image ...

Optimizing In-Place Density of Asphalt Pavements During Cold Weather Paving in Nebraska [PDF]

open access: yes, 2019
Late season paving is common and often performed in colder temperatures, which is the most challenging environment for attaining optimal in-place density/compaction The in-place density of asphalt pavement greatly affects the lifespan of the pavement. It

On reduced density matrices for disjoint subsystems

open access: yes, 2009
We show that spin and fermion representations for solvable quantum chains lead in general to different reduced density matrices if the subsystem is not singly connected.

Comparative Analysis of Pressure Drop (Δp): Hemodynamic Performance of Three Commercial Oxygenators During Cardiopulmonary Bypass

open access: yesArtificial Organs, EarlyView.
In this prospective study, a total of 60 patients were divided into three groups of 20 to compare the pressure drop (Δp) across three different oxygenators during cardiopulmonary bypass. The aim of this comparison was to enable evidence‐based optimization of the heart‐lung machine setup in order to minimize potential influencing factors and thereby ...

Non-Canonical Statistics of a Spin-Boson Model: Theory and Exact Monte-Carlo Simulations

open access: yes, 2012
Equilibrium canonical distribution in statistical mechanics assumes weak system-bath coupling (SBC). In real physical situations this assumption can be invalid and equilibrium quantum statistics of the system may be non-canonical.
