Outcomes of Filipinos with inflammatory rheumatic diseases developing COVID-19 prior to vaccinations and new variants: a historical perspective.

We described the profile and outcome of Filipino patients with inflammatory rheumatic diseases (IRDs) who developed COVID-19 (IRD-C19) during the onset of the pandemic, prior to vaccinations and variants. We obtained de-identified data of Filipino patients with IRD-C19 from the Global Rheumatology Alliance registry from March 2020 to August 2021. Descriptive statistics and multivariate analyses were applied.

Polariton Anomalous Hall Effect in Transition-Metal Dichalcogenides.

We analyze the properties of strongly coupled excitons and photons in systems made of semiconducting two-dimensional transition-metal dichalcogenides embedded in optical cavities. Through a detailed microscopic analysis of the coupling, we unveil novel, highly tunable features of the spectrum that result in polariton splitting and a breaking of light-matter selection rules. The dynamics of the composite polaritons is influenced by the Berry phase arising both from their constituents and from the confinement-enhanced coupling.

Hamiltonian Optics of Hyperbolic Polaritons in Nanogranules.

Semiclassical quantization rules and numerical calculations are applied to study polariton modes of materials whose permittivity tensor has principal values of opposite sign (so-called hyperbolic materials). The spectra of volume- and surface-confined polaritons are computed for spheroidal nanogranules of hexagonal boron nitride, a natural hyperbolic crystal. The field distribution created by polaritons excited by an external dipole source is predicted to exhibit raylike patterns due to classical periodic orbits.

Towards scalable nano-engineering of graphene.

By merging bottom-up and top-down strategies we tailor graphene's electronic properties within nanometer accuracy, which opens up the possibility to design optical and plasmonic circuitries at will. In a first step, graphene electronic properties are macroscopically modified exploiting the periodic potential generated by the self assembly of metal cluster superlattices on a graphene/Ir(111) surface. We then demonstrate that individual metal clusters can be selectively removed by a STM tip with perfect reproducibility and that the structures so created are stable even at room temperature.

[Effects of aerobic exercise program and relaxation techniques on anxiety, quality of sleep, depression, and quality of life in patients with fibromyalgia: a randomized controlled trial].

Background And Objective: Fibromyalgia is considered as a combination of physical, psychological and social disabilities. The purpose of the present study was to determine the benefits of aerobic exercise program and progressive relaxation techniques on anxiety, quality of sleep, depression and quality of life in patients with fibromyalgia.

Patients And Method: An experimental study was performed with a placebo control group.
