Isolating in-crystallo reaction intermediates during 4+4 light-driven cycloaddition

Kai-Chun YANG · Sylvain ENGILBERGE · Antoine ROYANT · Manuel MAESTRE-REYNA · y 2 más

Pentiptycene-anthracene (PAn-OCn) crystals are an ideal platform for delving into the fundamental aspects of in crystallo photochemical processes due to their light-driven [4+4] cycloadditive chemistry. In our previous experiments at the ESRF we used the unusual setup at the FIP2 (BM07) beamline, where an online micros...

A review of variational quantum algorithms: Insights into fault-tolerant quantum computing

Wang, Zhirao · Huang, Junxiang · Ye, Runyu · Li, Qingyu · y 7 más

Variational quantum algorithms (VQAs) have established themselves as a central computational paradigm in the Noisy Intermediate-Scale Quantum (NISQ) era. By coupling parameterized quantum circuits (PQCs) with classical optimization, they operate effectively under strict hardware limitations. However, as quantum archite...

CombiMet : Combinatorial metallurgy : high throughput mapping in time and compositional space of the microstructure of advanced alloys

Marion BREGEAULT · Olha NAKONECHNA · JOSE ANTONIO AGUILERA GARCIA (ORCID: 0009-0006-0177-240X) · Veijo HONKIMAKI · y 7 más

The design space of alloys encompasses composition and processing parameters. Exploring the link between these and the microstructure, which control properties, allows feeding materials models and design new alloys. CombiMet will set-up on ID31 a high throughput methodology that will improve drastically the efficiency...

Optimal linear baseline models for scientific machine learning

Alexander DeLise · Kyle Loh · Krish Patel · Meredith Teague · y 2 más

Across scientific domains, a fundamental challenge is to characterize and compute the mappings from underlying physical processes to observed signals and measurements. While nonlinear neural networks have achieved considerable success, they remain theoretically opaque, which hinders adoption in contexts where interpret...

THOR on board Space Rider prototype gamma-ray spectroscopic and polarimetric performance

José SOUSA · Gavin VAUGHAN · Rui Miguel CURADO DA SILVA (ORCID: 0000-0002-9961-965X) · Jorge Manuel MAIA PEREIRA · y 3 más

THOR-SR (TGF and High-energy astrophysics Observatory for gamma-Rays on board the Space Rider) mission is a high-energy astrophysics pathfinder ESA PRODEX mission (PEA: 4000141332) to be launched in the Space Rider maiden flight in 2025 Q3. It was designed to explore a range of phenomena that includes gamma-ray astroph...

Local structure changes by cryogenic rejuvenation in Dy-TM metallic glass

Wolf-Christian PILGRIM · Hanna Marita WENZEL · Shinya HOSOKAWA · Maxime DUPRAZ · y 1 más

In this proposal, we would like to carry out anomalous x-ray scattering (AXS) experiments on Dy-TM (TM = Co, Ni, Fe) metallic glasses (MGs) to obtain the relationship between the cryogenic rejuvenation effect and the changes in the local atomic structures. Our recent AXS experiments on a Gd65Co35 MG demonstrated that s...

Weak identification and estimation of social interaction models

Guy Tchuente

The identification of the network effect is based on either group size variation, the structure of the network or the relative position in the network. I provide easy-to-verify necessary conditions for identification of undirected network models based on the number of distinct eigenvalues of the adjacency matrix. Ident...

Growth and structure of thin CuO films in epitaxy on STO(001)

Veronique LANGLAIS ABAD · Maurizio DE SANTIS · Lucio MARTINELLI · Mahesh Krishna PRABHU · y 1 más

CuO is monoclinic and exhibits two antiferromagnetic phases, a polar incommensurate antiferromagnetic and multiferroic (AF2) one below TN=230 K and a non-polar commensurate AF1 phase below TN=213 K. We will grow thin CuO films in epitaxy on STO(001), study the structure by GIXRD and correlate it with their properties....

Calibration and performance of germanium high voltage detectors for SuperCDMS SNOLAB

M.F. Albakry · I. Alkhatib · D. Alonso-González · J. Anczarski · y 140 más

As SuperCDMS SNOLAB is getting ready to search for low mass dark matter particles, using cryogenic Ge and Si detectors, a set of six of the new SuperCDMS High Voltage (HV) detectors (four Ge and two Si) were tested in the Cryogenic Underground TEst facility (CUTE) at SNOLAB. This provided the first opportunity to gain...
