Trapping of low and high refractive index nano-spherical particles by using a highly focused Laguerre-Gaussian beam.

We have investigated the trapping force on low and high refractive index nano-particles using a highly focused Laguerre-Gaussian beam. An analytical expression for the gradient force has been derived in closed form. It was clearly found that the increase of the beam mode causes a substantial increase in the number of trapping zones, which frequently increases the number of particles to be captured simultaneously.

Is there a difference in the clinical profile and outcome of women using levonorgestrel IUD for abnormal uterine bleeding and those using it for contraception?: A comparative cross-sectional study.

Objective: The most common indications for Levonorgestrel intrauterine device (LNG-IUD) are contraception and management of abnormal uterine bleeding (AUB). This study was conducted with the aim of exploring the differences in the clinical profile and outcome of women using LNG-IUD for contraception and AUB.

Materials And Methods: This was a retrospective comparative cross-sectional study of women who underwent LNG-IUD (52 mg) between 2012 and 2017.

Pregabalin versus Gabapentin Efficacy in the Management of Neuropathic Pain Associated with Failed Back Surgery Syndrome.

Objective: Failed back surgery syndrome (FBSS) is a common long-term complication following spine surgeries characterized by chronic persistent pain; different strategies of management were employed to deal with it. This clinical trial aims to compare the efficacy of Pregabalin and Gabapentin in the management of this condition.

Methods: A double-blind, randomized, comparative study (clinical trial registry NCT05324761 on 11th April 2022) with two parallel arms with Pregabalin and Gabapentin were used in arms one and two, respectively.

Brain-based learning in design and visual arts education: a bibliometric assessment of Scopus indexed literature.

Background: This study aims to critically review, quantify, and assess research outcomes on brain-based learning with an evidence-based study on Scopus indexed literature, with a focus to understand the evolution structure and growth, detect trends, subject development, and most importantly, identify the gaps in the published body of literature that relates brain-based learning to design and visual arts education.

Methods: Various scientometric tools were used to map, visualize, and analyze 186 research publications, indexed in Scopus in a twenty-year timespan '2001-2021'. Annual publication trends, relevant sources, prolific authors, authorship patterns, productive organizations and countries, funding agencies, keyword co-occurrence analysis, and thematic evolution mapping on brain-based learning publications were examined in this study.
