Emproving the resolution of the finite-length sinusoids burried in noise (1997)

In the signal processing fields, sinusoidal wave is of much meaning because it may carry other important informations. But in reality due to the finite number of sensors along with the noise detected by the sensors, the resolution of frequency detection is in general much degraded. In this paper, new method is proposed to embrove the frequency resolution of the finite-length sinusoids burried in noise.

Dolichol is not a necessary moiety for lipid-linked oligosaccharide substrates of the mannosyltransferases involved in <i>in vitro</i> N-linked-oligosaccharide assembly (1995)

Dolichol is utilized in vivo as an unusually large anchor on which the precursor for N-linked oligosaccharides is assembled by a series of glycosyltransferases. The role of dolichol in enzyme substrate recognition is investigated. Thus the biosynthetic intermediate NN'-diacetylchitobiose was chemically linked to either dolichol or the much shorter fully saturated tetraisoprenoid phytanol. Both lipids were used as substrates by a recombinant, soluble beta-1,4-mannosyltransferase. beta-[3H]Mannosylated lipids from this reaction were then used as substrates for the subsequent mannosyltransferases from yeast or rat liver microsomes. It was found that both the dolichyl- and phytanyl-linked substrates were easily mannosylated to form Man5GlcNAc2, with some further mannosylation to Man7GlcNAc2 and Man9GlcNAc2 at low concentrations of lipid-linked substrate. It is concluded that dolichol is not necessary in vitro as part of the substrate for the mannosyltransferases in the biosynthetic pathway for N-glycosylation.
An inductive fuzzy classification approach applied to individual marketing (2009)

A new methodology for the induction of membership functions for fuzzy classification is introduced. The induction step is based on deriving membership functions from normalized likelihood ratios of target class membership. A case study is presented where this fuzzy data analysis process is applied in predictive analytics for an individual marketing campaign in the online channel of a financial service provider by selecting fuzzy target groups in a data warehouse.
Two electrode based healthcare device for continuously monitoring ECG and BIA signals (2018)

In this study, we propose an efficient wearable device to continuously and reliably monitor electrocardiogram (ECG) and body impedance (BI) that are two most important bio-signals for healthcare applications. Unlike most conventional systems that fail to synchronously provide a rich set of bio-signals because of their limitation on sensing a single type of signal, the proposed device faithfully analyzes a user's status only using two electrodes. To minimize measurement errors inherently induced by the sensing process caused by using two electrodes and sensing position dependency, we also propose an adaptive system control algorithm that are easy to switch the type of sensing signal and its measurement intervals by changing the setup parameters. Since the size of the device is very small and it is designed with a minimal belt-shape form for maximal user convenience, it is suitable for various types of wearable applications. Experiments performed in a couple of example healthcare scenario demonstrate the reliability of the proposed system.

The Male Urethral Sphincter Complex Revisited: An Anatomical Concept and its Physiological Correlate (2008)

The male urethral sphincter complex is composed of an inner lissosphincter of smooth muscle and an outer rhabdosphincter of skeletal muscle. It extends in the form of a cylinder around the urethra from the vesical orifice to the perineal membrane. While the rhabdosphincter is most marked around the membranous urethra and becomes gradually less distinct toward the bladder, the lissosphincter has its main part at the vesical orifice and is thinner in its further course in the urethra. The lissosphincter is primarily concerned with the function of continence at rest. On the other hand, the rhabdosphincter has a dual genitourinary function, namely active continence during stress conditions and antegrade semen propulsion.
A study on recovery of forest fire in Da Xing An Ling Using NOAA imagery. (1989)

1987年4月に中国とソ連の国境となっている黒龍江 (アムール河) をはさんで, 大規模な山林火災が起きた。中国の人民日報によると中国側だけで1987年5月から約一ヵ月間燃えつづけ, 東西幅約220km, 南北約90kmの範囲が燃えた。面積で言えば関東平野より広大な面積が燃えたことになる。火災直後にはLANDSATTMが大興安嶺の一部を把え, 中国科学院遙感衛星地面站は25万分の1縮尺の画像図「大興安嶺林火地区衛星影像平面図」を出版した。東京大学生産技術研究所のNOAAの受信局は, 山火事が鎮火した1987年7月6日に中国側被災地を比較的少ない雲量の画像として取得した。また, ほぼ一年後の1988年9月25日のNOAAの画像も山火事地域を把えている。山火事の生じた大興安嶺地区は中国において唯一の原生林地域であり, その森林資源の保護はきわめて重要な意味を有する。このような背景から, 本論文は, NOAA画像のグローバルな監視能力に着目し, 大興安嶺地区を調査区域として, 山火事の被害状況, 一年後の植生回復状況等を定量的に把握することを目的とする。
A novel hybrid-clamped four-level converter (2012)

A novel hybrid-clamped four-level inverter topology is proposed in this paper. Only two active switches and a floating capacitor are required as clamping devices per phase leg. The DC-link of this topology is subdivided into three parts and the voltage balancing of DC-link capacitors and floating capacitors can be achieved by selecting proper redundant switching states. The operating principle and voltage balancing method of this converter are introduced in details. Simulation and experimental results are presented to confirm the validity of this topology.

This paper presents design and implementation of Mosaicking algorithm. This technique is beneficial for providing authentic access as well as security to the biometric image template. We have designed an algorithm for fingerprint mosaicking in order to achieve the required performance. The proposed algorithm provides the effective solution of security issues regarding biometrics techniques without affecting the fingerprint quality. Results discussion section depicts the efficacy of proposed algorithm.
RNAi Targeting of West Nile Virus in Mosquito Midguts Promotes Virus Diversification (2009)

West Nile virus (WNV) exists in nature as a genetically diverse population of competing genomes. This high genetic diversity and concomitant adaptive plasticity has facilitated the rapid adaptation of WNV to North American transmission cycles and contributed to its explosive spread throughout the New World. WNV is maintained in nature in a transmission cycle between mosquitoes and birds, with intrahost genetic diversity highest in mosquitoes. The mechanistic basis for this increase in genetic diversity in mosquitoes is poorly understood. To determine whether the high mutational diversity of WNV in mosquitoes is driven by RNA interference (RNAi), we characterized the RNAi response to WNV in the midguts of orally exposed Culex pipiens quinquefasciatus using high-throughput, massively parallel sequencing and estimated viral genetic diversity. Our data demonstrate that WNV infection in orally exposed vector mosquitoes induces the RNAi pathway and that regions of the WNV genome that are more intensely targeted by RNAi are more likely to contain point mutations compared to weakly targeted regions. These results suggest that, under natural conditions, positive selection of WNV within mosquitoes is stronger in regions highly targeted by the host RNAi response. Further, they provide a mechanistic basis for the relative importance of mosquitoes in driving WNV diversification.
Functional coding of video using a shape-adaptive DCT algorithm and an object-based motion prediction toolbox (1997)

This paper presents an object-based layered video coding scheme which achieves very high compression efficiency along with the provision for advanced content-based functionalities, e.g., content-based scalability or content-based access and manipulation of video data. In a first step, a video sequence is segmented into several arbitrarily shaped "object layers." To achieve the desired content-based functionalities, a baseline shape-adaptive discrete cosine transform (DCT) coding algorithm is introduced which can be seen as an extension of conventional block-based DCT coding schemes (e.g., H.261, H.263, MPEG-1, or MPEG-2) toward coding of arbitrarily shaped image content. In order to increase compression efficiency, the baseline object-based layered approach can be extended with an object-based motion prediction toolbox. Using this toolbox, the coding scheme can potentially select specific prediction techniques for every object layer to be coded. To illustrate the concept, an extension of the baseline shape-adaptive DCT algorithm with a technique for global background motion estimation and compensation is described which significantly improves the compression efficiency of suitable video sequences compared to standard MPEG coding schemes.
Energy-conserving clustering scheme for multicastingin two-tier mobile ad-hoc networks (2001)

A distributed heuristic clustering scheme for multicasting is proposed to minimise transmission power in two-tier mobile ad-hoc networks. When the proposed scheme is implemented the average consumed power per master node is only slightly higher than the optimum result.
The Dynamics of Separation Control on a Rapidly Actuated Flap (2010)

Unsteady aerodynamic loads on a NACA 0021 airfoil during rapid flap deflections were investigated. Typical dynamic stall effects like an overshoot in lift, drag, and pitching moment have been observed. Flap deflection angle and speed were varied while the angle of attack remained constant at = 0 . To prevent stall and accompanying detrimental behavior, fluidic actuators generating discrete sweeping jets were integrated into the simple flap of the airfoil. Initial experiments at various angles of incidence but constant flap deflections proved that these actuators can prevent flow separation, increase lift, and decrease the drag of the airfoil. Dynamic tests revealed that sweeping jet actuators can also eliminate dynamic stall effects. A significant gain in lift and a substantial reduction in drag were achieved within a short period of time, even for high flap deflection angles of 30 .
3D Ordered Macroporous MoS<sub>2</sub>@C Nanostructure for Flexible Li‐Ion Batteries (2017)

A flexible and robust electrode is demonstrated by assembling the 3D ordered macroporous MoS2@C nanostructure on carbon cloth with ultrasmall few-layered MoS2 nanosheets homogenously embedded into the interconnected carbon wall.

Unsupervised Feature Learning Based on Deep Models for Environmental Audio Tagging (2017)

Environmental audio tagging aims to predict only the presence or absence of certain acoustic events in the interested acoustic scene. In this paper, we make contributions to audio tagging in two parts, respectively, acoustic modeling and feature learning. We propose to use a shrinking deep neural network (DNN) framework incorporating unsupervised feature learning to handle the multilabel classification task. For the acoustic modeling, a large set of contextual frames of the chunk are fed into the DNN to perform a multilabel classification for the expected tags, considering that only chunk (or utterance) level rather than frame-level labels are available. Dropout and background noise aware training are also adopted to improve the generalization capability of the DNNs. For the unsupervised feature learning, we propose to use a symmetric or asymmetric deep denoising auto-encoder (syDAE or asyDAE) to generate new data-driven features from the logarithmic Mel-filter banks features. The new features, which are smoothed against background noise and more compact with contextual information, can further improve the performance of the DNN baseline. Compared with the standard Gaussian mixture model baseline of the DCASE 2016 audio tagging challenge, our proposed method obtains a significant equal error rate (EER) reduction from 0.21 to 0.13 on the development set. The proposed asyDAE system can get a relative 6.7% EER reduction compared with the strong DNN baseline on the development set. Finally, the results also show that our approach obtains the state-of-the-art performance with 0.15 EER on the evaluation set of the DCASE 2016 audio tagging task while EER of the first prize of this challenge is 0.17.
Abstract 3298: Arsenic induces human bronchial epithelial cell transformation featured with tumor-initiating cells (2012)

Abstract Arsenic is a well-known human carcinogen. Chronic exposure to arsenic is associated with cancers in various tissues, including skin, urinary bladder, lung, liver, kidney and prostate. However, the mechanism underlying arsenic-induced carcinogenesis remains elusive. Here, we demonstrate that long-term (six month) exposure to low levels of sodium arsenite (0.25 µ M) in human bronchial epithelial cell line (BEAS-2B) results in altered morphology, increased cell proliferation and anchorage-independent colony formation in soft agar, indicative of malignant transformation of these cells. Moreover, tumorigenesis analysis revealed that s.c. inoculation of the arsenic-transformed cells can induce tumors in nude mice. The tumors can be observed after 2-3 weeks even only 500 arsenic-transformed cells were injected, suggesting that these transformed cells induced by long-term and low-dose arsenic treatment are highly tumorigenic. Additional studies indicated that some of these arsenic-transformed cells exhibit characteristics of tunor-initiating cells (TICs) or cancer stem cells (CSCs), such as overexpression of Oct3/4, Nanog, Sox2, Klf4, and C-myc. Tumor sphere formation assay, a general procedure in defining TICs or CSCs, suggested that about 5% of these arsenic-transformed cells can form tumor spheres in non-adherent plates. The tumor sphere forming cells were enriched through serial passage of the cells collected from tumor spheres. Flow cytometry sorting showed that 90% of these sphere cells are CD49f positive, whereas CD133, CD44, EpCAM, and c-kit were not detected. Overexpression of CD49f was confirmed by immunoblotting, which indicated an increased CD49f level in the arsenic-transformed cells relative to the non-transformed BEAS-2B cells. Finally, the ability of sphere formation and colony formation in soft agar was compared between the cells showed the strongest and the weakest CD49f expression and suggested that the cells with the strongest CD49f expression are more capable of forming tumor spheres and colonies. In conclusion, our data suggested that the transformed cells induced by arsenic have features of TICs or CSCs. Citation Format: {Authors}. {Abstract title} [abstract].

Determination of Therapeutic and Toxic Serum Digoxin Concentrations by Radioimmunoassay (1969)

A sensitive (0.2 ng per milliliter), precise (standard deviation 3 to 4 per cent), and specific radioimmunoassay for serum digoxin concentration has been developed. Levels are determined by measurement of the extent to which digoxin in the patient's serum competes with tritium-labeled digoxin, added in vitro, for digoxin-specific antibody binding sites. Mean values in nontoxic patients with normal renal function receiving 0.25 or 0.50 mg per day were 1.1 and 1.4 ng per milliliter respectively; the ranges fell within relatively narrow limits. Patients with cardiac arrhythmias attributed to digoxin toxicity had a mean level of 3.3 ng per milliliter, and little overlap with the nontoxic group (p less than 0.001). A determination can be completed in one hour, and may provide useful information to the clinician faced with the difficult problem of evaluating his patient's state of digitalization.
China’s Rubber Industry (2003)

Abstract This chapter describes the experiences of the rubber industry in China during the Sino-Japanese War. It discusses the specific experiences of the Da Zhonghua Rubber Company and the Zhengtai Rubber Company. The chapter explains that while the nascent rubber industry survived in the Shanghai area, Da Zhonghua and Zhengtai ultimately had to collaborate with the Japanese after December 1941 in order to remain in production. Most rubber manufacturers demonstrated a willingness to work with the Japanese military but a strong reluctance to surrender control of their enterprises to a Japanese business partner.
Synthesis of Cross-Linked Polyallylamines Which Are Resistant to Sulfite Attack (1982)

Abstract The effect of the type and amount of cross-linker, the monomer concentration, and the method of polymerization on the properties of some mine resins was studied. Resins were prepared by the free-radical initiated copolymerization of diallylamine or methyldiallylamine with a cross-linker such as 1,6-bis(N,N-dially1amino)hexane or triallylamine. Particular attention was given to controlling the factors responsible for the formation of pendant allyl groups in the resins since the presence of these groups is undesirable because they react with sulfite. Low monomer concentrations favored resins with low allyl content but the yield was also low. The best way of minimizing the number of pendant allyl groups is to use low levels of cross-linker. A resin with a very low pendant allyl group content, and therefore resistant to sulfite attack, was prepared from methyldiallylamine and 5 mol% 1,6-bis(N,N-dially1amino)hexane.
[Review: Prize-awarded article] Research on the Development of Innovative Application and Modifying Technology for the Carbohydrate Relating Enzymes (2012)

糖質関連分野では，酵素を利用し各種の糖質を生産している。これまで自然界から酵素を探索してきたが，必要な特性の酵素を見つけ出すのは容易ではない。そこで，酵素を遺伝子レベルで改変する技術を開発した。簡便に遺伝子にランダム変異を導入するRAISE法を確立した。さらに，遺伝子を大きく変異する手法を検討し，置換部位の特定方法，任意部位で置換する手法を開発し，β-グルコシダーゼ,キシラナーゼ等の酵素に適用し100を超える部分置換酵素(キメラ酵素)を構築し，分子活性を低下させることなく基質特異性を改変したり，熱安定性を向上させることに成功した。本手法は酵素の立体構造情報が得られない場合であっても，分子交配的に利用できる技術であることを明らかにした。また，改変遺伝子ではフォールディング能が失われ，封入体として得られる場合が少なくない。そこで，界面活性剤と包接多糖類を組み合わせた迅速リフォールディング系を開発した。
A methodological approach on real-time gesture recognition using multiple silhouette models (2002)

This paper describes a new method of real-time gesture recognition and its applications. The key idea of the method is that we use multiple silhouette models of human body and estimate the pose of arms and legs by comparing similarities of the input image to the models. To calculate the similarity for a certain specific part of the body, such as arms, a simple mathematical operation deducting the inference of different parts is adopted. As an application of gesture recognition, we realize a real-time interactive system, a gesture game, which can animate the game characters by gestures in real-time. Stretched arms like flying aeroplane, for example, can be interpreted into button operations for a flying simulation game with this system.
Web mining approach for a user-centered semantic Web (2005)

Abstract. In this paper, we propose a Web mining approach for the Semantic Web. The approach uses a search engine and the traditional web as a source of information to produce semantically rich information. In particular, we assess one community and obtain the social network and related information from the Web. As an example, we extract the social network of an academic society and show that extracted information can be incorporated into FOAF representation and utilized to measure the authoritativeness of a member in terms of social trust or individual trust. To demonstrate our Web mining approach in the real application, we show a researcher mining and retrieval system. Finally, we discuss the manner in which the Web mining approach contributes to availability to users of the Semantic Web. 1

Low-temperature bonding method based on metallic microcone array for interconnection application (2012)

Stacked bonding has become one of the key technologies of 3D IC. This paper reports a low-temperature solid state bonding method based on metallic microcone array for potential use in 3D integration applications. Sn-3.0Ag-0.5Cu solder balls with 760 μm diameter were used for the low-temperature BGA bonding. Ni micro cone layer was prepared by electro deposition and Cu micro cone layer was deposited by electroless plating, respectively. Bonding joints were shear tested to evaluate the joint strength of samples bonded at each pressure and temperature. Microscopic observation showed sufficient insertion between Sn and cone-structured Ni or Cu. Results showed that bonding strength was superior with proper bonding conditions.
