We propose a design of small-core multiple-layer Bragg waveguide for guiding the THz signal by TE01 mode, which is composed of alternating un-doped silicon (high refractive index) and high-density polyethylene (low refractive index). The group velocity of the THz wave traveling inside this small-core waveguide slows down to below 0.5c, while the propagation loss is less than 0.3 dB per centimeter...
In this study, we proposed an approach for constructing directed, regulatory gene set networks to reveal novel relationships among gene sets. Results from this study showed that regulatory gene set networks can provide complementary information to existing types of gene set networks and explain underlying mechanisms of a disease.
We present a class of fibers that exploit light propagation in higher-order modes, and hence decouple the dispersion-versus-mode-area trade-off encountered in conventional fibers. This enables exploiting the multitude of nonlinear optical effects afforded by fibers, at energy levels potentially approaching those of tunable solid-state lasers.
In this study, the nMOSFETs with contact-etch-stop-layer (CESL) stressor and SiGe channel have been fabricated with a modified 90-nm technology. The performance of nMOSFETs and stress distribution in the channel region have been investigated. The hot carrier reliability of the SiGe-channeled nMOSFETs with various CESL nitride layers has also been extensively studied. In addition, the impact of stress...
The aim of this study is to investigate the relationship between online gaming behavior and special underlying social group structures through the use of player information of a certain MMORPG. Data were collected from the logs of an MMORPG in 2011, recording five types of gaming behaviors, player gender, avatar gender and avatar occupation types to investigate whether different avatars affect gaming...
Synchronous discussion and asynchronous discussion have different advantages and disadvantages. However, it is unclear how students react to these two models. Thus, we developed a learning environment that combines these two models, and then examined how students selected them. The findings show that students selected different models at different discussion stages. Additionally, the mixed discussion...
Ge is an indirect bandgap material for research interest with possible photonic applications. In previous work, only direct bandgap emission was observed in the epitaxial Ge on Si, but both direct and indirect emissions were observed in the bulk Ge substrates. This discrepancy between epitaxial Ge and Ge substrate may be due to reabsorption of direct emission. In this work, the reabsorption is systematically...
The integration of TSVs and bonded structures is an important topic in 3D integration. In this study, fine Cu TSVs and various bonded structures, including Cu/Sn micro-bumps, Cu bond pads, and Cu alloy structures, are integrated and demonstrated. Electrical performances, morphology investigations, and reliability investigations of TSVs, bonded bumps/pads, and the integrated structures are studied...
Liquid chromatography-based tandem mass spectrometry (LC-MS) technique allows for identification and quantification of thousands of proteins in parallel. This technique coupled with a feed-forward artificial neural network provides a technique to analyze and select protein panels for use in multi-biomarker panel discovery applications. In this study, we enhance this technique by utilizing massively...
This paper proposes a novel nonlinear manifold learning method for addressing the ill-posed problem of occluded human action analysis. As we know, a person can perform a broad variety of movements. To capture the multiplicity of a human action, this paper creates a low-dimensional manifold for capturing the intra-path and inter-path contexts of an event. Then, an action path matching scheme can be...
This study is based on a simple hypothesis - “ideal” drugs for a patient can cure the patient's disease by modulating the gene expression profile of the patient to a similar level with those in healthy people, on the pathway level. To verify this hypothesis, we present a computational framework to evaluate drug effects on gene expression profiles in breast cancer. First, a breast cancer pathway model...
Pendidikan Sivik dan Kewarganegaraan or Civic Education and Citizenship is a compulsory subject for primary school students who are in Standard 4, Standard 5 and Standard 6. The advancement of technology has changed educational delivery methods. The use of game-based in learning environment has received increased attention from educators since games have assumed an important place in the lives of...
This paper demonstrates the needs of football websites in Equatorial Guinea (EG) which is one of the smallest country in African continent. The websites is designed with the purpose to encourage information sharing and promoting EG football team among football fans from inside and outside of EG. This research is initiated based on three (3) key factors : 1) EG people would like to promote their football...
