A single-chip self-contained speech recognizer (1983)

A fully integrated speech recognition LSI has been developed. The speech recognition LSI can recognize a speaker-dependent vocabulary of about 200 isolated words with high accuracy in real time, using several memories, which are a phoneme template memory, word dictionary memory, and work memory. This LSI is designed to perform the total speech recognition processing, including the endpoint detection of the input utterance in a self-contained manner. With the pipelined structure of the function blocks, highly efficient parallel operations are achieved. Furthermore, satisfactory testability is assured with a scan path technique. The speech recognition LSI is fabricated with 2 /spl mu/m E/D NMOS process technology, employing two aluminium interconnection layers and a high resistivity poly-Si layer.
Novel biomarker panel predicts prognosis in human papillomavirus‐negative oropharyngeal cancer (2011)

PWM Control Techniques for Rectifier Filter Minimization (1985)

Minimization of input/output filters is an essential step towards manufacturing compact low-cost static power supplies. Three PWM control techniques that yield substantial filter size reduction for three-phase (self-commutated) rectifiers are presented and analyzed. Filters required by typical line-commutated rectifiers are used as the basis for comparison. Moreover, it is shown that in addition to filter minimization two of the proposed three control techniques improve substantially the rectifier total input power factor.
Hormone-related factors and post-menopausal onset depression: Results from KNHANES (2010–2012) (2015)

Early menopause and the use of exogenous hormones were associated with the risk of post-menopausal depression. Clinicians should closely monitor and consider further screening for depressed women who undergo early menopause or those with exogenous hormone use.

Reaction of Decamethylsilicocene with Group 13 Element Halides:  Insertions, Rearrangements, and Eliminations (1999)

In the reaction of decamethylsilicocene (1; (Me5C5)2Si) with halides or organohalides of trivalent boron, aluminum, gallium, and indium, quite different and sometimes very complex pathways are observed which include adduct formation, 1,2-halide or -alkyl shifts, 1,2-dyotropic rearrangements, and reductive elimination and oxidative addition reactions. Cp*BCl2 (Cp* = pentamethylcyclopentadienyl), BCl3, and BBr3 reacted with 1 to form the pentacarba-nido-hexaboronium salts [Cp*SiCl2BCp*]+[Cp*BCl3]- (3a) and [Cp*SiX2BCp*]+[BX4]- (3b, X = Cl; 4, X = Br). A second product (5b) of composition Cp*3Si2Br4B with an arachno-cluster framework was isolated from the reaction with BBr3. With AlCl3 and AlBr3 metathesis reactions gave the ionic compounds [Cp*2Al]+[AlX4]- (6a,b, X = Cl, Br), respectively. The formation of 6a,b is the result of a Lewis-base-catalyzed dismutation of Cp*AlX2 in which 1 is the base, as proved by separate experiments. The compound Cp*Al(Me)Cl (7) was formed in the reaction of 1 with Me2AlCl. Silicocene 1 functioned as a dehalogenating agent in its reactions with GaCl3, GaBr3, Cp*GaBr2, InCl3, and InBr3, giving the corresponding monovalent, metastable (“GaCl”, “GaBr”) or stable (Cp*Ga, InCl, InBr) species. All new compounds were characterized by NMR (1H, 13C, 11B, 29Si) and mass spectrometry. The solid-state structures of 3a and 5b were determined by X-ray diffraction analysis.
An intelligent active alert application on handheld devices for emergency evacuation guidance (2013)

When an emergency occurs, like a fire alert, people usually follow the fixed escape route. However, they will not necessarily know where the fire is and which way would be the best route to exit the building. Sometimes people get panicky and the escape guidance might not be adequate or clear enough. In order to provide safe and correct guidance when emergencies happen, an emergency crowd guidance system was designed and implemented. In the system, a wireless sensor network, RFID, and a smart handheld device were integrated to provide a real-time, active, intelligent guidance system for fire evacuation. Moreover, an emergency guidance algorithm was run in the central control module of the proposed system displaying the evacuation route on mobile devices. Also, in the proposed system, the user can obtain information of the environment and get evacuation guidance with a well-marked arrow on a mobile device.
Formation of antiphase-boundary tubes and magnetization in Fe-35at.° Al by plastic deformation at 77K (1998)

Abstract The effects of plastic deformation on the microstructure and the magnetization in an Fe-35at.° Al alloy deformed at different temperatures have been examined. Changes in the susceptibility and the spontaneous magnetization have been measured as functions of strain and correlated with the development of the microstructure observed by high-voltage electron microscopy. Special interest is focused on the formation of the antiphase boundary tubes by superdislocation motion and its effect on magnetization. The increases in the susceptibility and the spontaneous magnetization have been attributed to the local change in the ordering of D03 and B2 phases by superdislocation motion, which is especially predominant at a low temperature possibly in the absence of dislocation climb.
A machine learning approach to inductive query by examples: An experiment using relevance feedback, ID3, genetic algorithms, and simulated annealing (1998)

Information retrieval using probabilistic techniques has attracted significant attention on the part of researchers in information and computer science over the past few decades. In the 1980s, knowledge-based techniques also made an impressive contribution to “intelligent” information retrieval and indexing. More recently, information science researchers have turned to other newer inductive learning techniques including symbolic learning, genetic algorithms, and simulated annealing. These newer techniques, which are grounded in diverse paradigms, have provided great opportunities for researchers to enhance the information processing and retrieval capabilities of current information systems. In this article, we first provide an overview of these newer techniques and their use in information retrieval research. In order to familiarize readers with the techniques, we present three promising methods: The symbolic ID3 algorithm, evolution-based genetic algorithms, and simulated annealing. We discuss their knowledge representations and algorithms in the unique context of information retrieval. An experiment using a 8000-record COMPEN database was performed to examine the performances of these inductive query-by-example techniques in comparison with the performance of the conventional relevance feedback method. The machine learning techniques were shown to be able to help identify new documents which are similar to documents initially suggested by users, and documents which contain similar concepts to each other. Genetic algorithms, in particular, were found to out-perform relevance feedback in both document recall and precision. We believe these inductive machine learning techniques hold promise for the ability to analyze users' preferred documents (or records), identify users' underlying information needs, and also suggest alternatives for search for database management systems and Internet applications. © 1998 John Wiley & Sons, Inc.
Precise determination of fictive temperature of silica glass by infrared absorption spectrum (2002)

In silica glass, the peak position of infrared absorption spectrum at around 2260 cm−1, which is related to the average of distribution of Si–O–Si bonding angle, is useful for determining frozen-in temperature of glass structure, the so-called fictive temperature. We precisely determined relation between the peak position and fictive temperature up to 1550 °C and found that at fictive temperatures higher than 1400 °C the present relation differs from the relation which has been extrapolated from the previous data at fictive temperatures below 1400 °C. The peak position was found to simply shift to lower wave numbers with raising fictive temperature. This suggests that at fictive temperatures up to about 1600 °C there is no maximum in density, which has been reported to exist at around 1500 °C.

Growth of high mobility GaN by ammonia-molecular beam epitaxy (1999)

The growth of high electron mobility GaN on (0001) sapphire by ammonia molecular beam epitaxy is reported. A buffer layer of AlN &lt;300 Å is initially deposited by magnetron sputter epitaxy, a technique where the aluminum source is a planar dc magnetron sputter cathode and ammonia is used for the nitrogen source. The GaN epilayer is deposited using a conventional K cell for the gallium source and ammonia for the nitrogen source. The layers were doped using silane. Measured room temperature electron mobilities of 560 cm2/V s were observed for layers with carrier densities of ∼1.5×1017 cm−3. The 4 K photoluminescence spectrum showed a very strong donor bound exciton at 3.48 eV with a full width at half maximum (FWHM) of 4.9 meV. X-ray diffraction studies showed the layers to have good crystallinity with FWHM of the ω–2θ and ω scans as low as 13.7 and 210 arcsec, respectively.
Pharmacokinetics of a non-narcotic analgesic, DA-5018, in rats (1998)

The pharmacokinetics of a non-narcotic analgesic, DA-5018, were compared after single intravenous (i.v.), subcutaneous (s.c.), and oral administrations, and after multiple (seven consecutive days) s.c. administration to rats. After i.v. administration of DA-5018, 1, 2, and 5 mg kg-1, the pharmacokinetic parameters of DA-5018 were independent of the dose ranges studied. After oral administration of DA-5018, absorption of the drug from gastrointestinal (GI) tract was fast, but the extent of absolute bioavailability (F) was low; the values were 23.2, 23.0, and 27.3% for 2, 5, and 10 mg kg-1, respectively. After single s.c. administration of DA-5018, absorption of the drug from the injected site was fast and the extent of absorption was fairly good; the F values were 74.5 and 71.8% for 2 and 5 mg kg-1, respectively. The lower F values after oral administration of DA-5018 to rats could be due to degradation of the drug in rat GI tract and/or considerable first-pass effect. After i.v., oral, and s.c. administration of DA-5018, the drug had a strong affinity to the rat tissues studied as reflected in the greater-than-unity tissue to plasma ratio. After i.v., oral, and s.c. administration of the drug, the biliary and urinary excretion of unchanged DA-5018 were negligible. There was no significant difference in the pharmacokinetics or tissue distribution of DA-5018 between single and multiple s.c. administration of the drug, 5 mg kg-1, to rats, indicating that there could be no tissue accumulation of the drug after multiple s.c. administration of the drug to rats.

Selective killing of glioma cell lines using an astrocyte-specific expression of the herpes simplex virus-thymidine kinase gene. (1998)

Gene therapy using the herpes simplex virus thymidine kinase gene (HSV-TK) is a promising new approach for the treatment of gliomas, a tumor type with a poor prognosis. To limit the toxic effects of this procedure, it is desirable to restrict expression of the HSV-TK gene to the target cells. This can be accomplished by use of the promoter of the glial fibrillary acidic protein gene, an intermediate filament protein expressed primarily in astrocytes. A plasmid containing the HSV-TK gene, driven by the human glial fibrillary acidic protein promoter gfa2, was lipofected into glioma cell lines and into an ovarian cancer cell line. Treatment with ganciclovir showed efficient killing of glioma cells, with no effect on the ovarian cells. Thus, the gfa2 promoter is a promising candidate for directing expression of toxic genes to gliomas.
Progesterone Produces Antinociceptive and Neuroprotective Effects in Rats with Microinjected Lysophosphatidic Acid in the Trigeminal Nerve Root (2012)

These results suggest that progesterone produces antinociceptive effects through neuroprotective action in animals with LPA-induced trigeminal neuropathic pain. Moreover, progesterone has potential utility as a novel therapy for trigeminal neuropathic pain relief at an appropriate managed dose and is therefore a possible future treatment strategy for improving the recovery from injury.

Molecular basis for the autonomous promotion of cell proliferation by angiogenin (2016)

Canonical growth factors act indirectly via receptor-mediated signal transduction pathways. Here, we report on an autonomous pathway in which a growth factor is internalized, has its localization regulated by phosphorylation, and ultimately uses intrinsic catalytic activity to effect epigenetic change. Angiogenin (ANG), a secreted vertebrate ribonuclease, is known to promote cell proliferation, leading to neovascularization as well as neuroprotection in mammals. Upon entering cells, ANG encounters the cytosolic ribonuclease inhibitor protein, which binds with femtomolar affinity. We find that protein kinase C and cyclin-dependent kinase phosphorylate ANG, enabling ANG to evade its inhibitor and enter the nucleus. After migrating to the nucleolus, ANG cleaves promoter-associated RNA, which prevents the recruitment of the nucleolar remodeling complex to the ribosomal DNA promoter. The ensuing derepression of rDNA transcription promotes cell proliferation. The biochemical basis for this unprecedented mechanism of signal transduction suggests new modalities for the treatment of cancers and neurological disorders.
The Ice Record of Greenhouse Gases (1993)

Gases trapped in polar ice provide our most direct record of the changes in greenhouse gas levels during the past 150,000 years. The best documented trace-gas records are for CO 2 and CH 4 . The measurements corresponding to the industrial period document the recent changes in growth rate. The variability observed over the last 1000 years constrains the possible feedbacks of a climate change on the trace gases under similar conditions as exist today. Changes in the levels of greenhouse gases during the glacial-interglacial cycle overall paralleled, at least at high southern latitudes, changes in temperature; this relation suggests that greenhouse gases play an important role as an amplifier of the initial orbital forcing of Earth's climate and also helps to assess the feedbacks on the biogeochemical cycles in a climate system in which the components are changing at different rates.
An Optimizable Circuit Structure for High-Efficiency Wireless Power Transfer (2011)

Since the magnetically resonant coupling was suggested for wireless power transfer (WPT), the theoretical analysis and experimental verifications of several resonant coupling structures have been investigated by several groups. Series-resonant and shunt-resonant structures are two common circuit models which are widely used in WPT. Here, a simple circuit topological structure, the series-shunt mixed-resonant coupling, is presented with better performance in the transfer distance and efficiency. In the experimental verification, a pair of resonant coils with 10-cm diameter was used. The experimental results show that high efficiency of 85% was achieved at a distance of 10 cm (one relative distance) and 45% efficiency at 20 cm (two relative distances). The proposed structure has another advantage that circuit parameters can be easily optimized for high transfer efficiency under different distances.
Ethnicity is associated with recurrence in patients with resected gastric cancer (2008)

15511 Background: Previous studies suggest that there are differences in survival among Asian and Caucasian patients with gastric cancer. It remains unclear whether disparities of treatment, differences in staging, or individual tumor biology account for this effect. The present study examines differences among ethnicities in time to tumor recurrence (TTR) in patients with resected gastric cancer. Polymorphisms in thrombin-receptor 1 (PAR1), endostatin (ES), and interleukin 8 (IL-8) are important in angiogenesis and have been implicated in gastric cancer recurrence. We tested whether the frequency of these polymorphisms provide a molecular basis for differences in TTR in different ethnic groups. Methods: Between 1992 and 2007, 105 patients (41 females and 64 males with a median age of 57 yrs; range = 26–85) with gastric adenocarcinoma underwent gastrectomy at the University of Southern California. There were 36 Caucasian, 1 African American, 24 Asian, and 44 Hispanic patients. The median follow-up was 2.4 years (range = 0.1–12.3). 47 of 105 patients (45%) developed tumor recurrence with a 5-year probability of 0.38 ± 0.06. We determined allelic frequencies of PAR1, ES, and IL-8 using PCR-RFLP. Results: Time to recurrence was significantly different by ethnic background (p=0.021, log-rank test). The median TTR for Asians was 7.0 yrs, for Hispanics was 3.7 yrs, and for Caucasians was 1.7 yrs. Gastroesophageal (GE) junction tumors had a shorter TTR compared to other tumor locations (2.1 yrs vs. 3.1 yrs, p=0.021). Allelic frequencies in genes for PAR1 and ES were statistically different between Asians, Hispanics, and Caucasians (PAR1 p=0.008; ES p=0.05), but there were no statistical differences for IL-8. Multivariate analyses including sex and age showed that ethnicity remained significant predicting TTR. Conclusion: Our study demonstrates significant differences in time to recurrence after gastrectomy favoring Asians and Hispanics. Genes in PAR1 and endostatin may provide a molecular basis for differences in TTR and may suggest different biologies of cancer between Caucasian, Hispanic, and Asian populations. Further studies are warranted to characterize molecular markers comparing different ethnic groups with resectable gastric cancer.

Design of Network Media’s Digital Rights Management Scheme Based on Blockchain Technology (2017)

There exist many unsolved problems in the traditional digital rights management of network media. For example, in the traditional management system it is hard to guarantee the quality of media works, to protect the copyrights, to find the effective profit model and so on. To solve these problems, we propose in this paper a network media's digital rights management scheme based on blockchain. Blockchain is a technology that makes use of cryptographic algorithm, hash chains and consensus mechanism to implement consensus, irreversibility and traceability for online data. The proposed scheme can use these functionalities of blockchain to implement the effective production management, copyright management, transaction management and users' behavior management for network media. Furthermore, our proposed scheme can predictively provide an important support for the network media platform to build a sustainable development of benign ecological environment.
Providing throughput guarantees in IEEE 802.11 wireless LAN (2003)

In this paper, we propose ARME (Assured Rate MAC Extension), an extension of the IEEE 802.11 MAC protocol to provide throughput guarantees. The proposed extension relies on the distributed coordination function (DCF) with a modified algorithm for the computation of the contention window (CW). Best effort service (with no throughput guarantee) is supported by the functionality of the current 802.11 standard in such a way that legacy IEEE 802.11 terminals behave as best effort terminals in ARME. The performance of the proposed extension has been extensively evaluated through simulation; simulation results show that IEEE 802.11 devices using ARME behave well for different types of traffic and different source rates.
An Introduction to Probabilistic Graphical Models for Relational Data. (2006)

1. Socially deprived children have higher caries levels than their more affluent counterparts and this is evident regardless of ethnic background. 2. Although Asian 14-15-year-old children have a higher periodontal treatment need than Whites, there was no ethnic influence on how they perceive their oral health. 3. Oral treatment need is an important factor with respect to oral self perceptions.
