Optimized absorption of light in perovskite nanowire solar cells.

Metal halide perovskite nanowires (PrvNWs) have recently emerged as an interesting path for nanostructured solar cells. Here, we model the absorption of light in PrvNW arrays for varying diameter and length of the PrvNWs and period for the array by solving the Maxwell equations. For long enough bare PrvNW arrays, we find that the optimum diameter is fixed to that which places the absorption peak from the HEwaveguide mode in the PrvNWs to the vicinity of the bandgap wavelength.

Obesity and incidence of colorectal polyps: a case-controlled study.

Unlabelled: Previous essays have presented possible concordance between obesity and colorectal polyp development. However, neither for the hypothesis nor for the details general consensus exists. This study aimed to evaluate the association between higher BMI rather than the normal and colorectal polyp presentation and characteristics if any.

A Multi-Criteria Decision-Making Model with Interval-Valued Intuitionistic Fuzzy Sets for Evaluating Digital Technology Strategies in COVID-19 Pandemic Under Uncertainty.

Coronavirus diseases 2019 (COVID-19) pandemic is an essential challenge to the health and safety of people, medical members, and treatment systems worldwide. Digital technologies (DTs) have been universally introduced to improve the treatment of patients during the pandemic. Nevertheless, only a few governments have been partly successful in executing the DT strategies.

Effect of Helicobacter pylori eradication in Iranian patients with functional dyspepsia: a prospective, randomized, placebo-controlled trial.

Introduction: Whether patients with functional dyspepsia (FD) should receive Helicobacter pylori (H. pylori) eradication therapy remains controversial. The objective of this trial was to evaluate the effect of H.
