We report an electroabsorption modulator (EAM)-integrated distributed Bragg reflector laser diode (DBR-LD) capable of supporting a high data rate and wide wavelength tuning. The DBR-LD contains two tuning elements, plasma heater tunings, both which are implemented in the DBR section, have blue-shift red-shift through current injection, respectively. light created from is intensity-modulated EAM...

Background This article explores the methodological foundations for a utopian methodology as form of Design-Based Intervention Research (DBR) that can guide process envisioning, implementing, sustaining, and critically evaluating more radical forms educational activity systems prefigure goal an equitable humane education system.Methods We examine, guided by lens, examples from three national tr...

Introduction: As part of the emergency response to COVID-19 pandemic, immediate breast reconstruction (IBR) following mastectomy was temporarily withdrawn allow re-prioritisation resources. The B-MaP-C study identified women treated during 'Alert' phase who would normally have been offered IBR. RESTORE C19 aimed explore ongoing management this group. Methods: Women not IBR initial pandemic were...

Previous studies using high-frequency ultrasound have suggested that radiofrequency (RF) spectral analysis can be used to quantify changes in cell morphology to detect cell death response to therapy non-invasively. The study here investigated this at conventional-frequencies, frequently used in clinical settings. Spectral analysis was performed using ultrasound RF data collected with a clinical...

Design-based research (DBR) and open source software are both acknowledged as potentially productive ways for advancing learning technologies. These approaches have practical benefits for the design and development process and for building and leveraging community to augment and sustain design and development. This report presents a case study of a software project using a design-based research...

This paper reports on a longitudinal, design-based research (DBR) study to promote clinical decision making using virtual patient (VP) simulation for emergency renal care. The VP was piloted with pharmacy students, then offered as an interprofessional learning exercise and medical before being introduced part of the curriculum. In this paper, DBR framework used design, implement evaluate is des...

We report a novel hemispherical micro-cavity that is comprised of a planar integrated semiconductor distributed Bragg reflector (DBR) mirror, and an external, concave micro-mirror having a radius of curvature 50 microm. The integrated DBR mirror containing quantum dots (QD), is designed to locate the QDs at an antinode of the field in order to maximize the interaction between the QD and cavity....

A methodology for design based research (DBR) into effective development and use of Multi-User Virtual Environments (MUVE) in vocational education is proposed. It blends software development with DBR with two theories selected to inform the methodology. Legitimate peripheral participation LPP (Lave & Wenger, 1991) provides a filter when thinking about vocational education because moving towards...
