On the retrieval of earliest memories.

Earliest memories were examined with respect to recollection type (i.e., remember-know), retrieval type (i.

The effect of visual and/or auditory distraction techniques on children's pain, anxiety and medical fear in invasive procedures: A randomized controlled trial.

Purpose: This study was conducted to determine the effects of visual and/or auditory distraction techniques applied to children aged 7-12 during invasive procedures on pain, anxiety, and medical fear.

Methods: This single-blinded, randomized controlled trial was carried out in the pediatric emergency department of a public hospital between November 2021 and March 2022. In the study, 144 children were assigned to three different intervention groups, in which a kaleidoscope, music, and virtual reality were applied during invasive procedures, and the control group in which the standard invasive procedure was applied, by using the stratified block randomization method.

off-axis electron holography of real-time dopant diffusion in GaAs nanowires.

Off-axis electron holography was used to reveal remote doping in GaAs nanowires occurring duringannealing in a transmission electron microscope. Dynamic changes to the electrostatic potential caused by carbon dopant diffusion upon annealing were measured across GaAs nanowires with radial p-p+ core-shell junctions. Electrostatic potential profiles were extracted from holographic phase maps and built-in potentials () and depletion layer widths (DLWs) were estimated as function of temperature over 300-873 K.

Thermal Conductivity of GaAs Nanowire Arrays Measured by the 3ω Method.

Vertical nanowire (NW) arrays are the basis for a variety of nanoscale devices. Understanding heat transport in these devices is an important concern, especially for prospective thermoelectric applications. To facilitate thermal conductivity measurements on as-grown NW arrays, a common NW-composite device architecture was adapted for use with the 3ω method.

Phase Diagram for Twinning Superlattice Te-Doped GaAs Nanowires.

Twinning superlattices (TSLs) are a growing class of semiconductor structures proposed as a means of phonon and optical engineering in nanowires (NWs). In this work, we examine TSL formation in Te-doped GaAs NWs grown by a self-assisted vapor-liquid-solid mechanism (with a Ga droplet as the seed particle), using selective-area molecular beam epitaxy. In these NWs, the TSL structure is comprised of alternating zincblende twins, whose formation is promoted by the introduction of Te dopants.
