France – Israel: consequences of the «October 7» by Alexander I. Shumilin

“…October 7, 2023, the day of the Hamas extremist attack on Israel, marked the beginning of powerful upheavals in the Middle East region. They echoed in the form of large-scale demonstrations in many cities of the European Union and in the Euro-Atlantic countries, having a noticeable impact on the domestic political balance of power there. …”

Differential impact from individual versus collective misinformation tagging on the diversity of Twitter (X) information engagement and mobility by Junsol Kim, Zhao Wang, Haohan Shi, Hsin-Keng Ling, James Evans

“…Individuals have increasingly challenged others’ online claims with fact-checks in pursuit of a healthier information ecosystem and to break down echo chambers of self-reinforcing opinion. Using Twitter (now X) data, here we show the consequences of individual misinformation tagging: tagged posters had explored novel political information and expanded topical interests immediately prior, but being tagged caused posters to retreat into information bubbles. …”

Political Psychology and Polarisation: A Conceptual Approach by Ekmel Geçer

“…This work then aims to shed valuable light on the dynamics of peace and political psychology in reducing digital polarization and how terms related to socio-cultural psychology like contact theory may increase intimacy and reduce prejudices towards the other which are most likely caused by the echo chambers created on the online platforms. Therefore, this theoretical research, uncovering the potential of peace psychology and drawing upon the relevant existing literature, has important implications for reducing political polarization, the digital divide in other words, on online media platforms which will also help overcome conflicts and discriminations in daily political lives.…”

In-vivo high-resolution χ-separation at 7T by Jiye Kim, Minjun Kim, Sooyeon Ji, Kyeongseon Min, Hwihun Jeong, Hyeong-Geol Shin, Chungseok Oh, Robert J. Fox, Ken E. Sakaie, Mark J. Lowe, Se-Hong Oh, Sina Straub, Seong-Gi Kim, Jongho Lee

“…Building on this development, we present a new pipeline for χ-separation at 7T, enabling us to generate high-resolution χ-separation maps from multi-echo gradient-echo data. The proposed method is compared with alternative pipelines, such as an end-to-end network and linearly-scaled R2′, and is validated against χ-separation maps at 3T, demonstrating its accuracy. …”

Three-Dimensional Storm Structure and Low-Level Boundaries at Different Stages of Cyclic Mesocyclone Evolution in a High-Precipitation Tornadic Supercell by Daniel P. Betten, Michael I. Biggerstaff, Conrad L. Ziegler

“…During part of the mesocyclone lifecycle, the SRFGF produced a band of low-level convergence and associated deep updraft along the southwestern side of the hook echo region that ingested the RFD outflow and limited both entrainment into the RFD and reinforcement of low-level convergence along the leading edge of the primary RFGF. …”

Joint High-Resolution Range and DOA Estimation via MUSIC Method Based on Virtual Two-Dimensional Spatial Smoothing for OFDM Radar by Rui Zhang, Ying-Hui Quan, Sheng-Qi Zhu, Lei Yang, Ya-chao Li, Meng-Dao Xing

“…It begins with the design and analysis of an echo model of OFDM array radar. Since there is no coupling between range and angle parameter estimation for a narrow-band signal, a method which exploits the data of one snapshot to estimate the range and angle of the target by means of multiple signal classification (MUSIC) based on virtual two-dimensional spatial smoothing in range and angle dimensions is devised. …”
