Continuous Subgraph Pattern Search over Graph Streams (2009)

Search over graph databases has attracted much attention recently due to its usefulness in many fields, such as the analysis of chemical compounds, intrusion detection in network traffic data, and pattern matching over users' visiting logs. However, most of the existing work focuses on search over static graph databases while in many real applications graphs are changing over time. In this paper we investigate a new problem on continuous subgraph pattern search under the situation where multiple target graphs are constantly changing in a stream style, namely the subgraph pattern search over graph streams. Obviously the proposed problem is a continuous join between query patterns and graph streams where the join predicate is the existence of subgraph isomorphism. Due to the NP-completeness of subgraph isomorphism checking, to achieve the real time monitoring of the existence of certain subgraph patterns, we would like to avoid using subgraph isomorphism verification to find the exact query-stream subgraph isomorphic pairs but to offer an approximate answer that could report all probable pairs without missing any of the actual answer pairs. In this paper we propose a light-weight yet effective feature structure called node-neighbor tree to filter false candidate query-stream pairs. To reduce the computational cost, we further project the feature structures into a numerical vector space and conduct dominant relationship checking in the projected space. We propose two methods to efficiently check dominant relationships and substantiate our methods with extensive experiments.
Distributed target tracking using self localizing smart camera networks (2010)

This paper describes a novel decentralized target tracking scheme for distributed smart cameras. This approach is built on top of a distributed localization protocol which allows the smart camera nodes to automatically identify neighboring sensors with overlapping fields of regard and establish a communication graph which reflects how the nodes will interact to fuse measurements in the network. The new protocol distributes the detection and tracking problems evenly throughout the network accounting for sensor handoffs in a seamless manner. The approach also distributes knowledge about the state of tracked objects amongst the nodes in the network. This information can then be harvested through distributed queries which allow network participants to subscribe to different kinds of events that they may be interested in. The proposed scheme has been used to track targets in real time using a collection of custom designed smart camera nodes. Results from these experiments are presented.
Chitin and chitosan dissolved in ionic liquids as reversible sorbents of CO2 (2006)

A novel dissolving process for chitin and chitosan has been developed by using the ionic liquid 1-butyl-3-methyl-imidazolium chloride ([Bmim]Cl) as a solvent, and a novel application of chitin and chitosan as substitutes for amino-functionalized synthetic polymers for capturing and releasing CO2 has also been exploited based on this processing strategy.
MPEG-H 3D Audio Decoder Structure and Complexity Analysis (2017)

MPEG-H 3D 오디오 표준은 UHDTV 등의 초고해상도 방송서비스에 대응하는 실감음향 서비스의 제공을 목표로 한다. 이를 위해 본 표준은 다채널 신호, 객체 신호, 장면 기반 신호의 부호화/복호화 기술과 다양한 재생 환경에서 3차원 오디오 제공을 위한 렌더링 기술, 후처리 기술 등 방대한 기술을 통합하였다. 본 표준의 참조 소프트웨어 복호화기는 여러 모듈들이 결합된 구조로 다양한 모드에서 동작이 가능하며, 각 모듈들이 독립된 실행파일로 순차적으로 실행되어 실시간 처리가 불가능하다. 본 논문에서는 MPEG-H 3D 오디오의 코어 복호화기, 포맷 변환기, 객체 렌더러, 바이노럴 렌더러의 각 함수를 동적 라이브러리화 및 통합하여 프레임 기반 복호화가 가능하도록 하였다. 또한 MPEG-H 3D 오디오의 각 모드별 연산량을 측정하여 다양한 하드웨어 플랫폼에서 적합한 모드를 선택하기 위한 참고 자료를 제공한다. 연산량 분석 결과, 한국 방송 표준에 포함된 저연산량 프로파일은 채널 신호로 렌더링을 할 경우 QMF 합성 연산의 2.8배에서 12.4배의 연산량을 가지며, 바이노럴 렌더링을 할 경우 QMF 합성 연산의 4.1배에서 15.3배의 연산량을 가진다. The primary goal of the MPEG-H 3D Audio standard is to provide immersive audio environments for high-resolution broadcasting services such as UHDTV. This standard incorporates a wide range of technologies such as encoding/decoding technology for multi-channel/object/scene-based signal, rendering technology for providing 3D audio in various playback environments, and post-processing technology. The reference software decoder of this standard is a structure combining several modules and can operate in various modes. Each module is composed of independent executable files and executed sequentially, real time decoding is impossible. In this paper, we make DLL library of the core decoder, format converter, object renderer, and binaural renderer of the standard and integrate them to enable frame-based decoding. In addition, by measuring the computation complexity of each mode of the MPEG-H 3D-Audio decoder, this paper also provides a reference for selecting the appropriate decoding mode for various hardware platforms. As a result of the computational complexity measurement, the low complexity profiles included in Korean broadcasting standard has a computation complexity of 2.8 times to 12.4 times that of the QMF synthesis operation in case of rendering as a channel signals, and it has a computation complexity of 4.1 times to 15.3 times of the QMF synthesis operation in case of rendering as a binaural signals.
InfoXLM: An Information-Theoretic Framework for Cross-Lingual Language Model Pre-Training (2020)

In this work, we present an information-theoretic framework that formulates cross-lingual language model pre-training as maximizing mutual information between multilingual-multi-granularity texts. The unified view helps us to better understand the existing methods for learning cross-lingual representations. More importantly, inspired by the framework, we propose a new pre-training task based on contrastive learning. Specifically, we regard a bilingual sentence pair as two views of the same meaning and encourage their encoded representations to be more similar than the negative examples. By leveraging both monolingual and parallel corpora, we jointly train the pretext tasks to improve the cross-lingual transferability of pre-trained models. Experimental results on several benchmarks show that our approach achieves considerably better performance. The code and pre-trained models are available at https://aka.ms/infoxlm.

Fault tolerant multiprocessor for digital switching systems (2003)

A description is given of the fault-tolerant multiprocessor used in the D70 digital switching system (the main model in Japan). The multiprocessor architecture adopts function sharing as well as load sharing to achieve expansion of processing power efficiently using small but reliable VLSI processors. The fault-tolerance objectives of this multiprocessor are based on the failure magnitude dependence concept, which specifies that the requirement for reliability increases with system size. The multiprocessor combines a redundant configuration and the fail-soft principle to achieve the objectives. The fault recovery procedure comprises four stages of the hierarchical structure. Fault influence propagation is limited using the rationality test for interprocessor communication on the call processing level. Field experience shows that the objectives are satisfied.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
RTFM: Publish/Subscribe Internetworking Architecture (2008)

We present a packet switched inter-networking paradigm different from the existing ones in that we argue for publish/subscribe (pub/sub) based networking architecture. The key idea of the paradigm is to distribute control over data reception from network endpoints to the network itself, and combine this with the way routing and forwarding is performed. In this paper, we outline the argumentation for the new paradigm and discuss its possibilities and challenges. We demonstrate the concept by presenting a prototype implementation and highlighting some lessons learned from local-area pub/sub networking.
Kinematic Design of Manipulators with Seven Revolute Joints Optimized for Fault Tolerance (2015)

A local definition of fault tolerance, based on properties of the manipulator Jacobian, is used to generate the kinematics of seven degree-of-freedom (DOF) revolute joint manipulators. The measure of fault tolerance used is the smallest singular value over all possible Jacobians resulting from single locked joint failures. The canonical form for an optimal fault-tolerant Jacobian that maximizes this measure has been previously identified. It has also been known that it is not possible to generate a seven DOF revolute manipulator that corresponds to this theoretically optimal Jacobian. However, in this paper, it is shown how to generate physically realizable Jacobians that are very close to being optimal. It is further shown that there exist 7! different manipulators, from a single Jacobian, that have the same local fault tolerance properties. To evaluate the global properties of these different manipulators, a technique for computing six-dimensional fault-tolerant workspaces is presented. The size of these workspaces vary significantly among these 7! manipulators.
Band tail states in microcrystalline silicon solar cells probed by photoluminescence and open circuit voltage (2005)

Thin film p-i-n microcrystalline silicon (mu c-Si:H) solar cells were studied by photoluminescence (PL) spectroscopy and open circuit voltage, V-oc. By this means, the cause of the commonly observed increase of V-oc when the silane concentration in the gas phase for the preparation of the intrinsic absorber layers is raised is addressed. The hot wire chemical vapour deposition (HW-CVD) technique was used for the preparation of films and intrinsic absorber layers of solar cells with efficiencies higher than 9%. By monitoring V-oc and the PL energy, E-PL, as a function of temperature, information on the photogenerated carrier distributions and the splitting of the quasi-Fermi energies was gained and the effect of states in the gap was studied by comparison with results from a crystalline p-i-n diode. An increase of E-PL and V-oc for increasing SC and decreasing temperature is attributed to the shift of the excess carrier distributions to higher energies. It is proposed that this shift is limited by band tail states. It is proposed that increasing SC leads to a reduction of the density of band tail states, due to structural relaxation of the mu c-Si:H network by the presence of hydrogen or hydrogenated amorphous silicon.
Accumulation of the Components of Total Solids in Ripening Fruits of Tomato (1993)

To identify qualitative and quantitative chemical variation in tomato fruit dry matter, crosses were made between the high soluble solids concentration (SSC) line LA 1501 (6.3% SSC when red-ripe) and the nearly isogenic commercial tomato cultivar VF 145B-7879 with a lower SSC (4.4% when red-ripe). Fruit samples from the parents and the reciprocal F 1 hybrids were collected at 3-day intervals, from 25 to 52 days after anthesis, to evaluate the accumulation of various quality components throughout the development of the fruit from immature-green to red-ripe stage. Fructose and glucose concentrations, titratable acidity, pH, and percent dry weight (pulp and serum) were determined for each sample on a fresh basis. Fruit maturity was evaluated by puree color using Hunter `a' colorimeter values. Changes in most of the chemical constituents of the fruit were found to regress linearly with changes in fruit color. Regression of puree color against fruit SSC, and fructose, glucose, and total sugar concentrations described more of the observed variability in these components than days after anthesis, indicating that Hunter `a' colorimetric values provide a more precise measurement of fruit physiological age. The variation between the parents in fruit dry matter was found to be primarily due to differences in SSC. The ratio of fruit soluble to total solids concentration increased 23.7% in LA 1501 (from 61.6% to 85.3%) throughout ripening compared to-an increase of only 8.9% (from 66.3% to 75.2%) in `VF 145B-7879'. At the red ripe stage, LA 1501 possessed a 44% higher SSC than `VF 145B-7879'. Differences in fructose and glucose accounted for 41% of the variation in SSC between the two lines. An unidentified component(s) was responsible for the residual variation. Application of the genetic and physiological information generated from this study can be used to isolate and select for genes controlling accumulation of tomato fruit dry matter.
<b>ULTRAVIOLET ACTION SPECTRA FOR DNA DIMER INDUCTION, LETHALITY, AND MUTAGENESIS IN <i>Escherichia coli</i> WITH EMPHASIS ON THE UVB REGION</b> (1984)

Abstract —Ultraviolet (UV) action spectra were obtained for lethality and mutagenesis (reversion to tryptophan independence) in Escherichia coli WP2s for wavelengths 254–405 nm with detailed analysis in the UVB region (290–320 nm). Parallel chemical assay yields of pyrimidine dimers in DNA of E. coli RT4 were determined at the same wavelengths. Spectral regions isolated from a Xe arc and resonance lines from a high‐pressure Hg‐Xe arc lamp were both used for irradiation. In all cases, precise energy distributions throughout the isolated Xe bands regions were defined. Lethality, mutagenesis, and dimer induction all decreased in efficiency in a similar fashion as the wavelengths of the radiation increased. Between 300 and 320 nm, all characteristics measured showed differences of about two and a half orders of magnitude. Between these wavelengths, the values of the three end points used either coincide with or parallel the absorption spectrum of DNA. The mutagenesis action spectrum coincides closely with the absorption spectrum of DNA. The lethality spectrum is closely parallel to the mutagenicity spectrum; the points, however, consistently occur at about 2 nm longer wavelengths. A calculation derived from the slope of the UVB spectra reveals that a 1‐nm shift of the solar UV spectrum to shorter wavelengths would result in a 35% increase in its mutagenic potential. At 325 nm, both biological action spectra show sharp decreases in slope. In addition, above 325 nm the spectra for lethality. mutagenicity, and dimer formation diverge sharply; lethalities at these UVA wavelengths were approximately tenfold greater relative to mutagenicity than at shorter wavelengths. The relative yield of dimer formation by 365 nm radiation is intermediate between the yields for lethality and mutagenesis.

Imatinib increases cytotoxicity of melphalan and their combination allows an efficient killing of chronic myeloid leukemia cells (2011)

BCR/ABL positive cells are known to be resistant to DNA damage induced by chemotherapy while they are sensitive to imatinib (IM), a tyrosine kinase inhibitor (TKI). To evaluate whether this drug can increase the activity of cytotoxic drugs on BCR/ABL positive cells, we measured the toxicity of cytosine arabinoside (ARA-C), hydroxyurea (HU) and melphalan (MEL), after a pretreatment of 24 h with IM on K562 cell line. The highest cytotoxic effect was seen when the TKI was followed by MEL; our results indicate that inhibition of BCR/ABL activity by IM increased the cytotoxicity of MEL by favoring the DNA damage induced by this drug and by shortening the time for DNA repair at the G2/M checkpoint. A stronger activation of some genes involved in both intrinsic and extrinsic apoptotic pathways was also observed with IM/MEL combination compared to IM or MEL alone. The drugs association was further tested in a type of BaF3 cells (TonB.210) where the BCR-ABL expression is inducible by doxycycline; in this model it was confirmed that a reduction of BCR/ABL activity resulted in an increased susceptibility to the cytotoxic effect of MEL. Furthermore, we studied the effect of IM/MEL treatment on the proliferative potential of myeloid progenitors of six CML patients at diagnosis. The analysis of CFU-GM and BFU-E colonies demonstrated that the IM/MEL combination was more effective than IM alone in reducing the overall number of colonies and the number of copies of BCR/ABL. In conclusion, our work shows that inhibition of BCR/ABL activity increases the toxicity of MEL and allows an efficient killing of leukemic cells, suggesting that a clinical development of this approach could have therapeutic advantages for CML patients.
Extracellular Nucleotides Induce Arterial Smooth Muscle Cell Migration Via Osteopontin (2001)

Migration and proliferation of arterial smooth muscle cells (SMCs) play a prominent role in the development of atherosclerotic plaques and restenosis lesions. Most of the growth-regulatory molecules potentially involved in these pathological conditions also demonstrate chemotactic properties. Extracellular purine and pyrimidine nucleotides have been shown to induce cell cycle progression and to elicit growth of cultured vascular SMCs. Moreover, the P2Y(2) ATP/UTP receptor was overexpressed in intimal thickening, suggesting a role of these nucleotides in vascular remodeling. Using the Transwell system migration assay, we demonstrate that extracellular ATP, UTP, and UDP exhibit a concentration-dependent chemotactic effect on cultured rat aortic SMCs. UTP, the most powerful nucleotide inducer of migration, elicited significant responses from 10 nmol/L. In parallel, UTP increased osteopontin expression dose-dependently. The blockade of osteopontin or its integrin receptors alpha(v)beta(3)/beta(5) by specific antibodies or antagonists inhibited UTP-induced migration. Moreover, the blockade of ERK-1/ERK-2 MAP kinase or rho protein pathways led to the inhibition of both UTP-induced osteopontin increase and migration, demonstrating the central role of osteopontin in this process. Taken together, these results suggest that extracellular nucleotides, and particularly UTP, can induce arterial SMC migration via the action of osteopontin.
