We propose a point-shifted D(0) nanocavity formed by locally modulating four central air holes in square lattice photonic crystal for optical sensing application. Three defect modes in this nanocavity, including monopole, whispering-gallery, and dipole modes, are identified in experiments. We also apply a chemical treatment on InGaAsP surface to form a 1-octadecanethiol linking monolayer, which enables the following protein adsorption. In experiments, the wavelength shifts of lasing modes in the D(0) nanocavity due to the protein adsorption are observed and agree with the simulation results. This can be a practical tool for label-free molecule detection in biomedical researches. (C) 2010 American Institute of Physics. [doi:10.1063/1.3436550]

A nonvolatile memory device with nanowire channel and a method for fabricating the same are proposed, in which side etching is used to shrink side walls of a side-gate to form a nanowire pattern, thereby fabricating a nanowire channel on the dielectric of the side walls of the side-gate. A nonvolatile memory device with nanowire channel and dual-gate control can thus be achieved. This nonvolatile memory device can enhance data writing and erasing efficiency, and also has the capability of low voltage operation. Moreover, through a process of low cost and easy steps, highly reproducible and mass producible fabrication of nanowire devices can be accomplished.

A method and apparatus for switching data in communication system which comprises of mainly a conversion circuit to receive source data possessing real coding dimension and covert it to converted data possessing tolerable coding dimension; judgment bit is set in the converted data to designate the data as source data or not. Later on, shift circuit is used to shift the converted data in certain amount so as to generate a shifted data; meanwhile, the lowest bit and highest bit of shifted data are used to start acquiring real coding dimension to be used respectively as a first data and a second data, or by changing the pattern of acquiring the first data, then the highest bit minus the real coding dimension bit as the starting bit of the first data, and acquiring the real coding dimension from the side of the lowest bit. Finally, a comparison and selection circuit is used to compare the corresponding judgment bit in the first and the second data and to output an output data, wherein output data is source data with the above-mentioned amount of shift.

A spatial light modulator applied to the collinear volume holographic storage system uses a hollow phase modulator to modulate the surrounding portion of an incident light to be a reference light, and the center portion of the incident light is modulated by an amplitude modulator to be a signal light. Thus, the spatial light modulator can enhance the convergence of the point spread function of the system.

An apparatus and method of multi-stage network for iterative network are disclosed. The apparatus has M stages, and each stage uses N multiplexers to transmit N codeword partitions simultaneously. Every starting terminal, either the output port of memories, soft-in soft-out decoders, or multiplexers, has two paths to couple with two different multiplexers at next stage. One path connects the source to the first data port of one multiplexer; the other connects the source to the second data port of another multiplexer. The two multiplexers will be controlled with the same 1-bit signal, so each source has only one valid path to next stage. The invention can guarantee that the transmission of N data blocks is free from contention.

A display includes a first substrate, a first electrode, a second substrate, a second electrode and a display material layer. The first electrode is disposed on the first substrate and the second electrode is disposed on the second substrate. The display material layer is disposed between the first electrode and the second electrode. The display material layer of the invented display includes a solution and a plurality of first micro beads, wherein each of the first micro beads further has a plurality of different axis lengths in different axis directions, and the axis length in at least an axis direction is different from the axis lengths in the rest axis directions so that the first micro beads present different arrangement densities in different driving frequencies under the influence of polarized self-arrangement effect.

A polymer vertical transistor with an on/off current ratio higher than 10(4) is demonstrated. The proposed space-charge limited transistor (SCLT) uses a metal-grid base containing high-density submicrometre openings to modulate the vertical space-charge-limited current (SCLC). The key to obtaining a high on/off current ratio is to reduce the leakage current of SCLT. In this paper, an improved device structure that isolates the grid metal by using both top and bottom insulating layers is demonstrated. Then, with an identical proposed structure, the geometric design is also found to significantly influence the on/off ratio over 3 orders of magnitude. The competition between the SCLC and the grid to collector leakage current is analysed. Finally, the influence of tetrafluoro-tetracyano-quinodimethane doping on the transistor characteristics is investigated. The results are important for the design of polymer vertical transistors with high on/off ratios.

The method is disclosed that Si+ is implanted on Si substrate to enhance strain relaxation at the interface between the metamorphic GexSi1−x buffer layers and Si substrate, in order to facilitate the growth of a high quality Ge on Si substrate. And several GexSi1−x buffer layers (Si/Ge0.8Si0.2/Ge0.9Si0.1/Ge) are grown on top of Si substrate by UHVCVD. Then grow pure Ge layer of low dislocation density on GexSi1−x buffer layer. Finally, grow up high efficiency III-V solar cell on GexSi1−x buffer layer.

In this work, n-GZO/a:amorphous-Si(i:intrinsic)/p(+)-Si photodiodes are fabricated. We employed a nanosphere lithographic technique to obtain nanoscale patterns on either the a-Si(i) or p(+)-Si surface. As compared with the planar n-GZO/p(+)-Si diode, the devices with nanopatterned a-Si(i) and nanopatterned p(+)-Si substrates show a 32% and 36.2% enhancement of photoresponsivity. Furthermore, the acceptance angle measurement reveals that the nanostructured photodiodes have larger acceptance angles than the planar structure. It also shows that the device with the nanocone structure has a higher acceptance angle than that with the nanorod structure.

Transient solution for radial two-zone flow in unconfined aquifers under constant-head tests

The constant-head test (CHT) is commonly employed to determine the aquifer parameters. This test is also applied to many environmental problems such as recovering light nonaqueous phase liquids (LNAPL) and controlling off-site migration of contaminated groundwater in low-transmissivity aquifers. A well skin near the wellbore may be produced due to the well construction or development and its formation properties are significantly different from the original ones. A more appropriate description for the skin effect on the aquifer system should treat the well skin as a different formation instead of using a skin factor. Thus, the aquifer system becomes a two-zone formation including the skin and formation zones. This study presents a mathematical model developed for analyzing a two-zone unconfined aquifer system and the associated solution for CHTs at partially penetrating wells under transient state. The solution of the model may be used either to identify the in situ aquifer parameters or to investigate the effects of the wellbore storage and well skin on the head changes in unconfined aquifers under constant-head pumping.

由於妥瑞症進入台灣的時間較晚，而且時常會與強迫症、過動症等一同併發，因此台灣仍有許多人對於妥瑞症一知半解，甚至是完全沒聽聞過，因而時常會對妥瑞症產生誤解。對於妥瑞人與其家長而言，最需要的其實只是社會的包容與諒解。

一般人對於自閉症的印象，不外乎智能障礙、表達溝通障礙、耍自閉、不愛與人互動、情緒起伏變化大等等，然而，這些觀念中僅包含了部分自閉症者的特性，甚至是社會大眾心裡存在的刻板印象。在今天社會中，自閉症者人數年年增加，而社會大眾對自閉症了解的多寡，也似乎決定了自閉症者如何被看待。

以性行為這個傳染途徑而言，安全性行為才是會不會染上愛滋的重點，與個人性向、性交方式等無關。如果非安全性行為，另一方又是愛滋帶原者，那麼不管是同性戀異性戀雙性戀口交肛交陰道交，通通都有「中獎」的機會。
