Controllable production of nanometre-sized structures is an important field of research, and synthesis of one-dimensional objects, such as nanowires, is a rapidly expanding area with numerous applications, for example, in electronics, photonics, biology and medicine. Nanoscale electronic devices created inside nanowires, such as p-n junctions, were reported ten years ago. More recently, hetero-...

The authors present a manufacturing cost analysis for producing thin-film indium phosphide modules by combining a novel thin-film vapor–liquid–solid (TF-VLS) growth process with a standard monolithic module platform. The example cell structure is ITO/n-TiO2/p-InP/Mo. For a benchmark scenario of 12% efficient modules, the module cost is estimated to be $0.66/W(DC) and the module cost is calculat...

This paper proposes a novel cache architecture suitable for merged DRAM/logic LSIs, which is called “dynamically variable line-size cache (D-VLS cache).” The D-VLS cache can optimize its line-size according to the characteristic of programs, and attempts to improve the performance by exploiting the high on-chip memory bandwidth on merged DRAM/logic LSIs appropriately. In our evaluation, it is o...

germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...

Self-catalyzed growth of GaAs nanowires are widely ascribed to the vapor-liquid-solid (VLS) mechanism due to the presence of Ga particles at the nanowire tips. Here we report synthesis of self-catalyzed GaAs nanowires by molecular-beam epitaxy covering a large growth parameter space. By carefully controlling the Ga flux and its ratio with the As flux, GaAs nanowires without Ga particles and exh...

BACKGROUND The authors evaluated the ability of visible light spectroscopy (VLS) oximetry to detect hypoxemia and ischemia in human and animal subjects. Unlike near-infrared spectroscopy or pulse oximetry (SpO2), VLS tissue oximetry uses shallow-penetrating visible light to measure microvascular hemoglobin oxygen saturation (StO2) in small, thin tissue volumes. METHODS In pigs, StO2 was measu...

This study investigated the types of vocabulary learning strategies (VLS) employed by Indonesian college students. The specifically aimed to find out (a) most and least frequently used VLS, (b) useful VLS. A total 105 nursing students who attended a virtual exchange program during odd semester 2021/2022 academic year participated in this study. was ex post facto research which strategy question...

In this work we provide theoretical background for the analysis of second-order correlation functions in experiments performed at soft x-ray free-electron lasers (XFELs). Typically, beamlines XFELs are equipped by variable line spacing (VLS) monochromators. We perform examination beam propagation through such VLS monochromator taking specially into account interplay between finite resolution an...

This study examined the involvement of intrastriatal dopaminergic mechanisms on feeding and spontaneous locomotor activity in food-deprived (19 h) rats. In three separate experiments, amphetamine (0, 1, 10, and 20 /lg/0.5 /ll) was bilaterally infused into the nudeus accumbens (N.Acc.), the ventrolateral striatum (VLS), or the dorsolateral striatum (DLS). Administration of the higher doses of am...
