Topological Spin Textures in an Insulating van der Waals Ferromagnet.

Generation and control of topological spin textures constitutes one of the most exciting challenges of modern spintronics given their potential applications in information storage technologies. Of particular interest are magnetic insulators, which due to low damping, absence of Joule heating and reduced dissipation can provide energy-efficient spin-textures platform. Here, it is demonstrated that the interplay between sample thickness, external magnetic fields, and optical excitations can generate a prolific paramount of spin textures, and their coexistence in insulating CrBr van der Waals (vdW) ferromagnets.

Writing and Detecting Topological Charges in Exfoliated FeGeTe.

FeGeTe is a promising two-dimensional (2D) van der Waals (vdW) magnet for practical applications, given its magnetic properties. These include Curie temperatures above room temperature, and topological spin textures─TST (both merons and skyrmions), responsible for a pronounced anomalous Hall effect (AHE) and its topological counterpart (THE), which can be harvested for spintronics. Here, we show that both the AHE and THE can be amplified considerably by just adjusting the thickness of exfoliated FeGeTe, with THE becoming observable even in zero magnetic field due to a field-induced unbalance in topological charges.

Intra-Abdominal Actinomycosis: An Indolent Masquerader of Malignancy.

This report describes the case of a 54-year-old female who presented with the constitutional symptoms of lethargy, weight loss, and asthenia. She had been extensively investigated for possible gynaecological malignancy but with no definitive outcome achieved. The symptoms were persistent and, partly due to occurring during the coronavirus disease 2019 (COVID-19) pandemic, a decision was made to progress with surgical management.

Coexistence of Merons with Skyrmions in the Centrosymmetric Van Der Waals Ferromagnet Fe GeTe.

Fe GeTe is a centrosymmetric, layered van der Waals (vdW) ferromagnet that displays Curie temperatures T (270-330 K) that are within the useful range for spintronic applications. However, little is known about the interplay between its topological spin textures (e.g.

Treatment and Maintenance of Cutaneous Rosacea in Latino Skin Types With Prescription Medications and Non-Prescription Cleansers and Moisturizers as Adjuncts: A Review.

Background: Rosacea is an inflammatory dermatosis with at least a ten percent prevalence reported among white adults. Rosacea occurs in nonwhite populations, but prevalence data is limited.

Methods: Five dermatologists from Latin America (the panel) met virtually after completing a survey of their prescription and adjunctive therapy practices when managing Latin American patients with rosacea.
