A precessing jet from a supermassive black hole: Multi-wavelength observations of S5 1044+71

M. Cerruti · P.A. Duverne · G. Ganesaratnam · P. Goswami · y 2 más

The bright gamma-ray blazar S5 1044+71 has been identified as showing very significant quasi-periodic oscillations in the Fermi-LAT data in recent studies, with a periodicity of about 3 years. With the completion of a new gamma-ray cycle, we aim to revisit the periodicity in Fermi-LAT data, and analyze all available mu...

Injury risk associated with the transition to minimalist footwear in runners: A systematic review and meta-analysis

Elisabeth Sánchez-Del, Río · Iriana, Galán-Arriero · Inés, Palomo-Fernández · Félix, Marcos-Tejedor · y 1 más

Running-related injuries have remained relatively stable over recent decades despite advances in athletic footwear design. This has led to a growing interest in minimalist footwear as a strategy for modifying running biomechanics. However, the effects of its use and the optimal characteristics of the transition period...

A privacy-preserving distributed congestion management framework via implicit differentiation bilevel optimization

Xin Li · Sen Zhan · Haoyang Zhang · Koen Kok · y 1 más

The growing integration of flexible distributed energy resources (DERs), such as hybrid heat pumps (HHPs), provides distribution system operators (DSOs) with valuable tools to manage grid congestion. Traditional approaches typically model the interaction between DSOs and prosumers with flexibility resources as a bileve...

In situ compression and mechanical characterization of nature-inspired meta-grain lattices

Paul TAFFOREAU · Henry SAUNDERS · Alexander SLOANE · Jaianth VIJAYAKUMAR · y 5 más

Additive Manufacturing (AM) lattices exhibit high stiffness/strength-to-weight and specific energy absorption, providing great benefits to the transport and biomedical industries. Meta-grains - a topological feature inspired by Bravis lattices that can improve mechanical performance of lattices [1]. We are currently in...

Optical coherence tomography for dynamic monitoring of resin infiltration kinetics: an exploratory ex vivo study

Yurong Liu · Yonggang Xiang · Kang Zhang · Xin Xia · y 4 más

This study aimed to investigate the relationships between etching and infiltration durations and their corresponding depths using optical coherence tomography (OCT), develop preliminary time-depth predictive models, and evaluate the ex vivo performance of OCT-optimized individualized resin infiltration (OCT-IRI) for en...

Metal uptake and distribution by Toxoplasma gondii

Clare PERRY · Erin GIBSON · Dana AGHABI · Hiram CASTILLO · y 1 más

Transition metals, such as iron and zinc, play essential roles during infection. Our work focuses on the eukaryotic parasite Toxoplasma gondii, a ubiquitous pathogen of humans and animals, which needs to subvert transition metals from its host cells to power the parasite's replication. We have identified the proposed i...

Unveiling the electrode reaction for the High Entropy Nasicon materials NaM2(PO4)3 (M = Al, Fe, Mn, Zn, Nb, Cr, V, Ti) as anodes for recharg

Nicolò PIANTA · Martina FRACCHIA (ORCID: 0000-0001-5366-153X) · Ivan Claudio PELLINI · Francesco D ACAPITO

The design of highly performing anodes for Na-Ion Batteries is a mandatory step for their commercialization. Here the study of new compositions of High Entropy Nasicon (NA Super Ionic CONductors) with formula NaM2(PO4)3 with M = Al, Fe, Mn, Zn, Nb, Cr, V, Ti is proposed by means of XAS techniques to identify the electr...

Single Crystal X-Ray Diffraction Investigation of High Tc Sc-H Mixtures

Umbertoluca RANIERI · Pierre-Olivier AUTRAN · AKUN LIANG · James SPENDER · y 1 más

Recent experiments have demonstrated an astonishing close-to-room-temperature superconductivity (Tc ~ 250 K) in laser-heated Y-H and La-H mixtures between 170 GPa and 200 GPa. While this is a game-changer in our understanding of condensed matter physics, these pressures are far too high for technological applications....

High temperature sintering mechanics of site-specific lunar regolith simulants

Jennifer SUTHERLAND · Manfred BURGHAMMER

We aim to generate a baseline fundamental description of high-fidelity lunar regolith simulants, with a particular emphasis on the intra- and inter-granular phase and amorphous distribution during sintering and recrystallization. Samples consist of metal-oxides and mineral composites in grain size and chemical concentr...

Synthesis of chromium-doped YAG nanocrystals via Pechini synthesis and coprecipitation

Audrey POTDEVIN · Romain THEVENET · Denis TESTEMALE

Chromium IV-doped Yttrium Aluminum Garnet (YAG) materials are widely used as saturable absorbers (SA) in YAG:Nd lasers. However, the low doping rate (about 1%at) reported in literature leads to poor SA properties whereas the complex doping mechanism of the matrix leads to a cohabitation between various ions: Cr3+, octa...
