Antiferromagnetic spin canting and magnetoelectric multipoles in h-YMnO3

Hexagonal YMnO3 is a prototype antiferromagnet which exhibits multiferroic behavior with the ferroelectric and magnetic transitions occurring at different temperatures. We observe an out-of-plane canting of the Mn3+ magnetic moments using resonant x-ray diffraction (RXD) in a single crystal of this material. These canted moments result in the symmetry-forbidden (0,0,1) magnetic Bragg reflection, w

Using network analysis to validate domains of the modified telephone interview for cognitive status

BackgroundThe modified Telephone Interview for Cognitive Status (TICS-M) is a widely used tool for assessing global cognitive functions and screening for cognitive impairments. The tool was conceptualised to capture various cognitive domains, but the validity of such domains has not been investigated against comprehensive neuropsychological assessments tools. Therefore, this study aimed to explore

Complex dynamics in adaptive phase oscillator networks

Networks of coupled dynamical units give rise to collective dynamics such as the synchronization of oscillators or neurons in the brain. The ability of the network to adapt coupling strengths between units in accordance with their activity arises naturally in a variety of contexts, including neural plasticity in the brain, and adds an additional layer of complexity: the dynamics on the nodes influ

Light-Controlled Multiphase Structuring of Perovskite Crystal Enabled by Thermoplasmonic Metasurface

Halide perovskites belong to an important family of semiconducting materials with electronic properties that enable a myriad of applications, especially in photovoltaics and optoelectronics. Their optical properties, including photoluminescence quantum yield, are affected and notably enhanced at crystal imperfections where the symmetry is broken and the density of states increases. These lattice d

Ett skattesystem för Sverige i en global värld

Sänk skatten på arbete, inför enhetlig moms och rak kapitalbeskattning. Det föreslår nationalekonomen Åsa Hansson i en ny SNS-rapport. Mycket har förändrats sedan den stora skattereformen 1990–91. Om skattesystemet görs om utifrån dagens förutsättningar kan Sverige få högre tillväxt och sysselsättning, menar hon.

From resolution to resecuritization: populist communication of the AKP’s Kurdish peace process in Turkey

This article contributes to the existing literature on the populist online communication of governments. We look at the role of the micro-blogging social media platform Twitter under the authoritarian rule of President Recep Tayyip Erdoğan and the wider Justice and Development Party (Adalet ve Kalkınma Partisi; AKP) during the peace process. We carried out a rhetorical analysis of the Twitter post

Handbook of Nuclear Medicine and Molecular Imaging for Physicists : Instrumentation and Imaging Procedures, Volume I

This state-of-the-art handbook, the first in a series that provides medical physicists with a comprehensive overview into the field of nuclear medicine, is dedicated to instrumentation and imaging procedures in nuclear medicine. It provides a thorough treatment on the cutting-edge technologies being used within the field, in addition to touching upon the history of their use, their development, an
