The observation of ferromagnetism in magnetic ion doped II–VI diluted magnetic semiconductors (DMSs) and oxides, and later in (Ga,Mn)As materials has inspired a great deal of research interest in a field dubbed “spintronics” of late, which could pave the way to exploit spin in addition to charge in semiconductor devices. The main challenge for practical(More)
Transient changes in cardiovascular regulatory activities are valuable for clinical monitoring and pathophysiological research. However, there is a lack of effective methods to evaluate short-term cardiovascular regulation. This study explores a photoplethysmography (PPG)-based multi-parameter analytical approach using the period, amplitude and baseline of(More)
Osteoporosis is a serious health problem worldwide and leads to a significant burden on society. Unfortunately, efforts to control osteoporosis are largely unsuccessful. Lowering an individual's risk for osteoporosis must focus not only on treatment but also on modification of risk factors. One of the common risk factors is smoking tobacco. Here, we review(More)
Bioinspired special wettibilities including superhydrophobicity and tunable adhesive force have drawn considerable attention because of their significant potential for fundamental research and practical applications. This review summarizes recent progress in the development of bioinspired wetting surfaces via laser microfabrication, with a focus on(More)
A fast and single-step process is developed for the fabrication of low-cost, high-quality, and large-area concave microlens arrays (MLAs) by the high-speed line-scanning of femtosecond laser pulses. Each concave microlens can be generated by a single laser pulse, and over 2.78 million microlenses were fabricated on a 2 × 2 cm(2) polydimethylsiloxane (PDMS)(More)
Polystyrene sphere was chosen as a catalyst to fabricate indium-tin-oxide (ITO) nanowires (NWs) with a low-temperature (280-300 °C) electron-beam deposition process, bearing high purity. The ITO NWs with diameter of 20-50 nm and length of ~2 um were obtained. X-ray diffraction and high-resolution transmission electron microscope show high crystal quality.(More)
A novel pulsed rapid thermal processing (PRTP) method has been used for realizing the solid-phase crystallization of amorphous silicon films prepared by PECVD. The microstructure and surface morphology of the crystallized films are investigated by X-ray diffraction (XRD) and atomic force microscopy (AFM). The results indicate that this PRTP is a suitable(More)
Cloud computing is becoming more and more mature, and an IaaS cloud computing model called Cloud Bank [1], which is based on commercial bank model, has been designed. Could Bank model can be partly distinguished from other traditional IaaS providers by the sources of infrastructure resources. The new cloudbank model follows the way of commerce bank to(More)
Very short-term heart rate variability (HRV) is thought to reflect dynamic changes in autonomic nervous activity, which is helpful in understanding the role of autonomic nervous function (ANF) in the mechanisms underlying apnea-induced cardiac arrhythmias. The goal of this study was to investigate the effect of repetitive end-inspiration breath holding on(More)
