We consider magnetotransport properties in a conducting chiral helimagnet, where the magnetic kink crystal (MKC) is formed under weak magnetic field applied perpendicular to the helical axis. The MKC behaves as a magnetic superlattice potential and results in Bragg scattering of conduction electrons. Tuning of the weak magnetic field enables us to control the size of the superlattice Brillouin zone and gives rise to a series of divergent resistivity anomalies originating from resonant Bragg scatterings. We discuss as well a nontrivial magnetic structure in the resonant states realized in the subsystem of the itinerant electrons.

Incidence of optic nerve kinking in a cohort of patients with Normal tension glaucoma.

Department of Biomedicine, University of Basel, Basel, Switzerland.
Objectives: To report on the incidence of optic nerve kinking in a series of patients diagnosed with normal-tension glaucoma (NTG) compared to an age- and gender matched control group without known optic nerve diseases.
Subjects And Methods: All patients with NTG who underwent imaging (computed tomography cysternography (CTC) or magnetic resonance imaging (MRI)) of the orbits and cranium between 2012 and 2022 were included, totalling 57 patients (27 females and 30 males; 57 eyes; mean age 69 ± 10 years). 57 age- and gender matched subjects without known optic nerve diseases who underwent MRI of the orbits and cranium served as controls.
Invariant solutions, lie symmetry analysis, bifurcations and nonlinear dynamics of the Kraenkel-Manna-Merle system with and without damping effect.

This work investigates the Kraenkel-Manna-Merle (KMM) system, which models the nonlinear propagation of short waves in saturated ferromagnetic materials subjected to an external magnetic field, despite the absence of electrical conductivity. The study aims to explore and derive new solitary wave solutions for this system using two distinct methodological approaches. In the first approach, the KMM system is transformed into a system of nonlinear ordinary differential equations (ODEs) via Lie group transformation.

With the help of a microscopic model and Green's function technique, we studied the multiferroic and phonon properties of the recently reported new multiferroic PrFeAlO (PFAO) compound, which belongs to the double perovskite ABB'O family. The magnetization decreases with the increase in temperature and disappears at the ferromagnetic Curie temperature TCFM. The polarization increases with the application of an external magnetic field, indicating strong magnetoelectric coupling and confirming the multiferroic behavior of PFAO.

In a first theoretical investigation of the multiferroic properties of Pb5Fe3F19 (PFF) and Pb5Cr3F19 (PCF), we analyze their magnetic, ferroelectric, and dielectric characteristics as functions of temperature, magnetic field, and ion doping concentration using a microscopic model and Green's function theory. The temperature-dependent polarization in PFF and PCF shows a distinctive kink at the magnetic Neel temperature TN, which vanishes when an external magnetic field is applied, indicating the multiferroic behavior of these two compounds. Ion doping effectively tunes the properties of PFF and PCF.

Department of Cardiovascular Surgery, Yamato Seiwa Hospital, Kanagawa, Japan.
Introduction: Hemolytic anaemia from graft kinking is a rare complication after aortic surgery, typically treated by graft replacement. This case highlights hemolytic anaemia caused by the interaction of aortic stenosis and a kinked graft, successfully managed with transcatheter aortic valve replacement (TAVR).
Presentation Of Case: A 75-year-old male developed hemolytic anaemia 2 years after total aortic arch replacement for a saccular aneurysm, with a worsening graft kink and aortic stenosis.
