ABSTRACT The optimized optical design of GaN resonant cavity light emitting didoes (RCLEDs) emitting at 510nm for maximum extraction efficiency into numerical apertures (NAs) of 1.0 (total emission) and 0.5 (typical plastic optical fiber NA) are determined using a modeling tool based on the simulation of dipole emission in a multilayer structure. The optimization is performed for a metal-AlGaN/...

BACKGROUND The present work assesses the effect of immediate breast reconstruction (IBR), deferred breast reconstruction (DBR), and no breast reconstruction on the psychological impact. PATIENTS AND METHODS Standard questionnaires were used to determine the psychological impact suffered by patients who underwent IBR, DBR and no reconstruction, their degree of satisfaction with the results ach...

A novel free-standing resonant-cavity-enhanced (RCE) Ge thin-film absorber is designed with a bottom distributed Bragg reflector (DBR) for infrared photodetection at 1550 nm wavelength based on Si substrate. The structure offers high degree of freedom in optimizing the number periods, layer arrangement, and thickness each DBR. SiO2/Si DBR that compatible processing technology used thin film to ...

This paper reports on one cycle of a design-based research (DBR) study in which mCSCL was explored through an iterative process of (re)designing and testing the collaboration and learning approach with students. A unique characteristic of our mCSCL approach is the student-led emergent formation of groups. The mCSCL application assigns each student a component of a Chinese character and requires...

The MVC+D standard specifies coding of Multiview Video plus Depth (MVD) data for enabling advanced 3D video applications. MVC+D defines that all views are coded with H.264/MVC encoder at equal spatial resolution. To improve compression efficiency it is possible to use mixed resolution coding in which part of texture views are coded at reduced spatial resolution. In this paper we evaluate the pe...

BACKGROUND AND AIM Spaced restudy has been typically tested with written learning materials, but restudy with visual representations in actual classrooms is under-researched. We compared the effects of two spaced restudy interventions: A Diagram-Based Restudy (DBR) warm-up condition and a business-as-usual Text-Based Restudy (TBR) warm-up condition. SAMPLE One hundred and twenty-eight consent...

Three-dimensional (3D) backside reflector, compared with flat reflectors, can improve the probability of finding the escape cone for reflecting lights and thus enhance the light-extraction efficiency (LEE) for GaN-based light-emitting diode (LED) chips. A triangle-lattice of microscale SiO2 cone array followed by a 16-pair Ti3O5/SiO2 distributed Bragg reflector (16-DBR) was proposed to be attac...

The design-based research (DBR) methodology has been standing out in the field of educational promising to adapt different scenarios and boost development innovations. However, 17 years after beginning use this methodology, there are still doubts about its potentiality. Given this, it is necessary ascertain which contexts used what advances related it. Thus, bibliometric mapping was carried pap...

Adiabatic following has been an widely-employed technique for achieving near-complete population transfer in a `two-level' quantum mechanical system. The theoretical basis, however, could be generalized to broad class of systems exhibiting SU(2) symmetry. In the present work, we analogy dynamics two level atomic system with that light propagation classical `one-dimensional' photonic crystal, co...

Chirp compensation is demonstrated using voltage division to a long-section electroabsorption phase modulator together with an amplitude modulator arranged in a tandem configuration, both integrated with an SOA and a sampled-grating DBR laser.
