Spin-1/2 Heisenberg chains with Dzyaloshinskii–Moriya interaction: critical exponents of the Σ⁺ phase near T_c

Haddad, I., Rao, P., Moreau, L.

In schools around the world students are sorted to different groups, courses, or classes. In increasingly diverse societies, such sorting practices play an important role to social cohesion. They set the structural conditions for students to form friendships across demographic divides. This article highlights the importance of attribute consolidation in learning contexts, the extent to which demog... [see more]

Wide-field cellular-resolution retinal imaging using deformable mirror-based sensorless adaptive optics time-domain full-field OCT

Cai, Y., Martinache, O., Bertrand, M., Callet, C., Thouvenin, O., Grieve, K., Mecê, P.

Adaptive optics (AO) enables cellular-resolution retinal imaging by correcting ocular aberrations, but its widespread clinical adoption remains limited by the narrow field of view (FOV) imposed by the isoplanatic patch of the eye. In this study, we present a deformable mirror (DM)–based sensorless AO time-domain full-field OCT (FFOCT) system that overcomes these limitations by leveraging the inher... [see more]

Pulse-by-pulse ultra-high resolution scintillation imaging of proton FLASH beams produced by a gantry-mounted synchrocyclotron

Goddu, S., Holloingsworth, S., Green, W., Goddu, M., Mazur, T., Owen, D., Zhang, H., Hao, Y., Perkins, S., Darafsheh, A.

Objective. Radiation therapy at ultra-high dose rate (UHDR) has emerged in the past decade as a novel technique with potential to improve the therapeutic index through a phenomenon referred to as ‘FLASH effect’. Its reliable pre-clinical studies and safe clinical deployment would benefit from dosimeters with high spatiotemporal resolution, ideally with capability to perform pulse-by-pulse dosimetr...

Intrinsic asymmetric iontronic-interfaces for giant power generation: methods and sensitivity checks

Lefèvre, L., Okafor, K.

Iontronic power source harnesses ion-electron coupling effect for energy conversion, offering great potential in wearable electronics and bioelectronics. However, its limited power density and insufficient current hinder the progress toward commercialization. Here we report an iontronic electricity generator based on intrinsic asymmetric interfaces and controllable energy-release, which reaches a ... [see more]

Friendship segregation and class composition in schools: A systematic analysis of the role of attribute consolidation (JOS DOCX counterpart)

Böller, S., Kruse, H.

In schools around the world students are sorted to different groups, courses, or classes. In increasingly diverse societies, such sorting practices play an important role to social cohesion. They set the structural conditions for students to form friendships across demographic divides. This article highlights the importance of attribute consolidation in learning contexts, the extent to which demog... [see more]

Effect of Fe and Si Content on Microstructure and Properties of Al-Cu-Li Alloys: extended analysis

Kapoor, N., Dubois, L., Osei, T., Johansson, M., Silva, L., Delacroix, C., Sørensen, S., Dąbrowski, K., Reyes, B., Hayashi, A.

This study systematically investigates the effects of Fe and Si impurities on the microstructure and mechanical properties of Al-Cu-Li alloys. Five alloy compositions with controlled Fe (0.03–0.12 wt.%) and Si (0.03–0.12 wt.%) contents were fabricated and processed through homogenization, hot extrusion, solution treatment, and aging. Microstructural characterization demonstrates that Fe promotes t... [see more]

Bengali cyberbullying detection: A comprehensive dataset for advanced analysis

Jahin, G., Maliha, F., Nafisa, N., Hassan, M., Patwary, M.

Cyberbullying has become a major concern in the digital world, with social media platforms facilitating harmful interactions that target individuals. Although there has been significant research, studies specifically focusing on Bengali cyberbullying remain scarce. This paper addresses this gap by analyzing over 70,000 social media comments in the Bengali language. The dataset is preprocessed for ... [see more]
