Indistinguishable single photons from a quantum dot in a nanopost cavity
Wavelength-tunable sources of single photons are key devices for scaling up optical quantum technologies. In this context, individual quantum dots (QDs) embedded in broadband photonic nanostructures are particularly appealing. The nanopost cavity, which is built with a segment of...

Use of waste marble powder as a cement substitute in three-dimensionally printable mortars
The potential of Tunisian marble waste as a sustainable partial substitute for cement in mortars for three-dimensional printing (3DP) for construction applications was explored. Marble powder (MP) generated from cutting and finishing processes was characterised through X-ray diff...

Learning Sequences and Events in Individual, Pair and Group Data-Driven Learning
Abstract Previous research has shown that the learning process in data-driven learning (DDL) is cyclical, iterative, and non-linear, even when tasks are designed around seemingly linear pedagogical frameworks such as Illustration–Interaction–Intervention–Induction (Carter, Ronald...

Rocks out, waste in: A double penalty in gravel-rich river valleys?
Construction and Demolition (C&D) waste is the largest solid waste stream in France, yet circular economy (CE) research on this sector tends to privilege technical and quantitative framings over its socio-economic and governance dimensions. This article examines the implementatio...

Conformal Assembly of Platinum on Self-Standing Structured Cathodes for PEMFCs
Abstract A self-standing cathode architecture for proton exchange membrane fuel cells was developed. A conformal, thin layer of platinum was electrodeposited on a self-standing carbon-fiber-based structured support in the form of an extended-surface particulate film. Abundant gra...

Ultra-compact plasma photocathode in a hybrid wakefield accelerator
Abstract Plasma-based particle accelerators, realized by driving plasma waves with either an intense laser pulse or particle beam, offer accelerating fields orders of magnitude higher than conventional accelerators. This enables sources of highly relativistic electron beams with...

Background Podoconiosis is a chronic, disfiguring, non-filarial form of lymphedema caused by prolonged barefoot exposure to irritant soil. An estimated four million people are affected globally, with cases documented in more than 32 countries, 18 of which are in Africa. In Rwanda...

Abstract. Changes in sea ice concentration (SIC) and derived sea ice extent have been monitored using microwave radiometers since the late 1970s, providing information about the polar response to climate change, making SIC an invaluable variable for numerical models. Antarctic se...

Ediacaran coupling of climate and biosphere dynamics
Climate change is demonstrably linked to radiations, extinctions, and turnovers in the biosphere throughout the Phanerozoic (538.8 Ma to present). Here, we suggest this connection existed as early as the late Ediacaran (ca. 579−538.8 Ma), the first interval in Earth’s history to...

We propose an implementation model for the evaluation of the weak λ-calculus, which is invariant for both time and space complexity, in both call-by-name and call-by-value strategies. In other words, this model provides an implementation of any weak call-by-name or weak call-by-v...

Efficient quantum implementation of dynamical mean field theory for correlated materials
The accurate theoretical description of materials with strongly correlated electrons is a formidable challenge in condensed matter physics and computational chemistry. Dynamical Mean Field Theory (DMFT) is a successful approach that predicts behaviors of such systems by incorpora...

Abstract Background Metabolic reprogramming is a hallmark of breast cancer (BrCa), with alterations in glycolysis, glutamine metabolism, and the urea cycle contributing to tumour progression. Dichloroacetate (DCA), a pyruvate dehydrogenase kinase (PDK) inhibitor, shifts metabolis...

This article extends tail-call optimisation by applying it to asynchronous calls. We first introduce TMA, a novel code transformation for asynchronous tail recursive functions that prevents the creation of unnecessary tasks. We then show how to combine TMA with the existing TMC o...

What does a territory tell? Co-constructing heritage through complex social values in inner contexts
Italian inner areas are increasingly affected by depopulation, demographic ageing, and territorial fragmentation. In these contexts, cultural heritage is frequently mobilised as a resource for local development and regeneration. While heritage studies have widely recognised that...

Detection of spiking motifs of arbitrary length in neural activity using bounded synaptic delays
In the context of spiking neural networks, the temporal coding hypothesis is increasingly preferred over the rate coding hypothesis due to its advantages in processing speed and energy efficiency. In temporal coding, synaptic delays are crucial for processing signals with precise...

Background Spinocerebellar Ataxia 27B (SCA27B) is a novel, frequent and likely treatable late-onset autosomal-dominant ataxia caused by GAA repeat-expansions in FGF14 . For understanding disease evolution and imminent trial planning, metrics of the most widely used clinical outco...
