The electrical transport properties of field effect transistor (FET) devices made of silicon nanowires (SiNWs) synthesized by pulsed laser vaporization (PLV) were studied. From as-grown PLV-SiNW FET, we found pchannel FET behavior with low conductance. To improve conductance, spin on glass (SOG) and vapor doping were used to dope phosphorus and indium into SiNW, respectively. From doping after ...

abstract this study addresses two dimensional infiltration from irrigated furrows. the basic approach is to develop a two-dimensional infiltration as a combination of the corresponding one-dimensional vertical and an edge effect. the edge effect is the difference between the cumulative infiltration per unit of adjusted wetting perimeter and the corresponding one-dimensional infiltration. this a...

BACKGROUND Despite of higher pregnancy rate after frozen embryo transfer (FET) which is accepted by the majority of researches, the safety of this method and its effect on neonatal outcome is still under debate. OBJECTIVE The aim of this study was to evaluate pregnancy and neonatal outcome of FET compare to fresh cycles. MATERIALS AND METHODS In this study,1134 patients using fresh ET and 2...

An extended-gate field-effect-transistor (FET) sensor with a gold-sensing electrode, to which a gold-thiol bond could easily be applied, was developed for DNA detection. Because the gold electrode is located in a different area from the FET, it can be operated without a light-shielding box by masking only the FET. However, when the FET sensor is used in an aqueous solution, fluctuation of the i...

BACKGROUND The use of assisted reproductive technology (ART) is increasing in the world. The rate, efficacy and safety of ART are very different among countries. There is an increase in the use of intra cytoplasmic sperm injection (ICSI), single fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET). OBJECTIVE The objective of this study was to compare pregnancy rate in fresh ET a...

UNLABELLED Many low-grade gliomas (World Health Organization grade II) respond to chemotherapy. Cerebral blood flow (CBF) and microvessel density may be critical for drug delivery. We used PET with (18)F-fluoro-ethyl-l-tyrosine (FET) to measure the spatial distribution of the amino acid carrier, which is located at the brain capillaries, and (15)O-H(2)O to measure tumor CBF. METHODS Seventeen...

UNLABELLED The goal of this study was to evaluate the (18)F-labeled nonnatural amino acid (S)-2-amino-3-[1-(2-(18)F-fluoroethyl)-1H-[1,2,3]triazol-4-yl]propanoic acid ((18)F-AFETP) as a PET imaging agent for brain tumors and to compare its effectiveness with the more-established tracers O-(2-(18)F-fluoroethyl)-l-tyrosine ((18)F-FET) and (18)F-FDG in a murine model of glioblastoma. The tracer (1...

Lateral and vertical two-dimensional heterostructure devices, in particular graphene-MoS2, have attracted profound interest as they offer additional functionalities over normal two-dimensional devices. Here, we have carried out electrical and optical characterization of graphene-MoS2 heterostructure. The few-layer MoS2 devices with metal electrode at one end and monolayer graphene electrode at ...

BACKGROUND 18 F-fluoro-ethyl-tyrosine PET is gaining more indications in the field of oncology. We investigated the potentials of usage of FET-PET/CT in addition to MRI for definition of gross tumor volume (GTV) in stereotactic radiotherapy of lesions of skull base. METHODS We included in a prospective setting 21 cases. An MRI was performed, completed by FET PET/CT. Different GTV's were defin...
