Uptake of and intention to use oral pre-exposure prophylaxis for HIV among pregnant and post-natal women in Eswatini: a cross-sectional survey.

Introduction: In Eswatini, HIV incidence among women of childbearing age is 1.45%. Eswatini introduced oral pre-exposure prophylaxis (PrEP) for HIV prevention in 2016 and requires that all HIV-negative pregnant and post-natal women (PPW) visiting health care facilities be offered PrEP.

Registered nurses' perspectives on barriers of cervical cancer screening in Swaziland: a qualitative study.

Introduction: cervical cancer is highly preventable and curable if diagnosed and treated early, however, it is still the leading cause of death among women. Despite efforts to increase cervical cancer screening, its uptake is still low. The purpose of the study was to investigate the perspectives of registered nurses on barriers of cervical cancer screening in Swaziland.

Phase-field crystal for an antiferromagnet with elastic interactions.

We introduce a model which contains the essential elements to formulate and study antiferromagnetism, using the phase-field crystal framework. We focus on the question of how magneto-elastic coupling could lift the frustration in the two-dimensional hexagonal antiferromagnetic phase. Using simulations we observe a rich variety of different phases stable in this model.

Grain Boundary Structures and Collective Dynamics of Inversion Domains in Binary Two-Dimensional Materials.

Understanding and controlling the properties and dynamics of topological defects is a lasting challenge in the study of two-dimensional materials, and is crucial to achieve high-quality films required for technological applications. Here grain boundary structures, energies, and dynamics of binary two-dimensional materials are investigated through the development of a phase field crystal model that is parametrized to match the ordering, symmetry, energy, and length scales of hexagonal boron nitride. Our studies reveal some new dislocation core structures for various symmetrically and asymmetrically tilted grain boundaries, in addition to those obtained in previous experiments and first-principles calculations.
