Rice is known as an ammonium (NH4 +)-tolerant species. Nevertheless, rice can suffer NH4 + toxicity, and excessive use of nitrogen (N) fertilizer has raised NH4 + in many paddy soils to levels that reduce vegetative biomass and yield. Examining whether thresholds of NH4 + toxicity in rice are related to nitrogen-use efficiency (NUE) is the aim of this(More)
ZnTe is an important p-type semiconductor with great applications as field-effect transistors and photodetectors. In this paper, individual ZnTe nanowires based field-effect transistors was fabricated, showing evident p-type conductivity with an effect mobility of 11.3 cm(2)/Vs. Single ZnTe nanowire based photodetectors on rigid silicon substrate exhibited(More)
BACKGROUND An important purpose of orthodontic treatment is to gain the harmonic soft tissue profile. This article describes a novel way to build patient-specific models of facial soft tissues by transforming a standard finite element (FE) model into one that has two stages: a first transformation and a second transformation, so as to evaluate the facial(More)
BACKGROUND Hypertension is a major risk factor for the development of stroke. It is well known that lowering blood pressure decreases the risk of stroke in people with moderate to severe hypertension. However, the specific effects of calcium channel blockers (CCBs) against stroke in patients with hypertension as compared to no treatment and other(More)
We have recently proposed that the interaction between food components and nanoparticles (NPs) should be considered when evaluating the toxicity of NPs. In the present study, we used THP-1 differentiated macrophages as a model for immune cells and investigated the combined toxicity of low levels of palmitate (PA; 10 or 50μM) and ZnO NPs. The results showed(More)
Cloud computing emerges as a new computing paradigm concerned by both academia and industry. Resource management of multiple virtual machines is the core of Infrastructure as a Service. Focusing on the CPU resources, the purpose of this paper is to increase the QoS of web service by properly scheduling the CPU resource across the virtual machines. We(More)
Zn(3)P(2) is an important p-type semiconductor with the ability to detect almost all visible and ultraviolet light. By using the simple and efficient contact printing process, we reported the assembly of horizontally-aligned p-type Zn(3)P(2) nanowire arrays to be used as building blocks for high performance photodetectors. Horizontally-aligned Zn(3)P(2)(More)
INTRODUCTION The present study developed and tested a Chinese version of the Yale Food Addiction Scale (YFAS-R-C) in a sample of female normal-school students, with the aim of producing a psychometrically sound tool for assessing food addiction in female adolescents. METHODS A preliminary study of 72 normal-school students tested the YFAS-R-C and(More)
