Support concept-based multimedia information retrieval: a knowledge management approach (1999)

Identified as an important management concept five years ago (Garner 1999), knowledge management (KM) aims to enable organizations to capture, organize, and access their intellectual assets. This paper proposes a prototype system that applies a knowledge management approach to support concept-based multimedia information retrieval by integrating various information analysis and image processing techniques. The proposed system uses geographical information as its testbed and aims to provide flexibility to users in terms of specifying their information needs and to facilitate parallel extraction of information in different formats (i.e., text, image). Our testbed selection is based not only on the fact that geographical information has become an important resource supporting organization decision making, but also on the diversity of its information media and the fuzziness of geo-spatial queries. We hope that the proposed system will improve the accessibility of geographical information in different media and provide an example of integrating various information and multimedia techniques to support concept-based cross-media information retrieval.
Rating Scales for Depression (2009)

Over the past few decades, a number of clinician-rated and patient-rated instruments have been developed as primary efficacy measures in depression clinical trials. All those scales have relative strengths and weaknesses and some of them have been more successful than others, and have become the gold standards for depression clinical research. With all these measures available and with the evidence of their variable performance in clinical trials, it is becoming increasingly important to select primary efficacy measures that are reliable, valid, and that fit well within the aims of depression clinical trials. This article will review the main considerations that investigators need to make when choosing a primary efficacy measure for major depressive disorder (MDD). There is a clear need for a thorough discussion of the methodological issues concerning the use of these scales, as suggested also by Demyttenaere and De Fruyt in a recent review [1], because clinical trials researchers in depression continue to struggle with the ability to detect signals of the efficacy of antidepressant agents.

Adaptive tracking and model registration across distinct aspects (2002)

A model registration system capable of tracking an object through distinct aspects in real-time is presented. The system integrates tracking, pose determination, and aspect graph indexing. The tracking combines steerable filters with normalized cross-correlation, compensates for rotation in 2D and is adaptive. Robust statistical methods are used in the pose estimation to detect and remove mismatches. The aspect graph is used to determine when features will disappear or become difficult to trade and to predict when and where new features will become trackable. The overall system is stable and is amenable to real-time performance.

Our findings indicate that the human heart has a significant growth reserve and replaces its myocyte and nonmyocyte compartment several times during the course of life.
Thermal Properties of Bentonite-Water Dispersions Used for Modeling Foods (1984)

Selected thermal properties (moisture content, density, heat capacity, thermal conductivity) were measured for ten bentonite-water dispersions used in food modeling, and for bentonite powder. As the bentonite concentration increased, significant (P < 0.05) increases in thermal conductivity and density, and significant (P < 0.05) decreases in heat capacity were revealed. Measured heat capacity values were lower than calculated values of heat capacity which were derived from three formulas recommeded for foods.

Speed estimation in uplink frequency domain for mobile OFDM systems (2014)

The speed of user equipment (UE) is significant in improving the performance of orthogonal frequency division multiplexing (OFDM) systems. Estimating the speed can help in adaptively allocating resources to users, reducing call drop rate in handoff, selecting the optimal radiation pattern, etc. The Doppler spread caused by the relative movement between transmitter and receiver can be utilized to estimate UE speed. Many Doppler spread estimation algorithms have been studied in recent years, such as zero crossing rates (ZCR) algorithm, level crossing rates (LCR) algorithm and autocorrelation function (ACF) algorithm. In this paper, we propose a novel speed estimation method for mobile OFDM systems based on autocorrelation function, where UE speed is estimated in uplink frequency domain on the base station (BS) side. Simulation results demonstrate that the proposed method can estimate UE speed accurately and is more robust to noise.
Visual Mining of Multi-Modal Social Networks at Different Abstraction Levels (2007)

Social networks continue to become more and more feature rich. Using local and global structural properties and descriptive attributes are necessary for more sophisticated social network analysis and support for visual mining tasks. While a number of visualization tools for social network applications have been developed, most of them are limited to uni-modal graph representations. Some of the tools support a wide range of visualization options, including interactive views. Others have better support for calculating structural graph properties such as the density of the graph or deploying traditional statistical social network analysis. We present Invenio, a new tool for visual mining of socials. Invenio integrates a wide range of interactive visualization options from Prefuse, with graph mining algorithm support from JUNG. While the integration expands the breadth of functionality within the core engine of the tool, our goal is to interactively explore multi-modal, multi-relational social networks. Invenio also supports construction of views using both database operations and basic graph mining operations.
Analysis and design of helical capacitance sensors for volume fraction determination (1979)

The Niemann-Pick type C2 protein loads isoglobotrihexosylceramide onto CD1d molecules and contributes to the thymic selection of NKT cells (2007)

The Niemann-Pick type C2 (NPC2) protein is a small, soluble, lysosomal protein important for cholesterol and sphingolipid transport in the lysosome. The immunological phenotype of NPC2-deficient mice was limited to an impaired thymic selection of Valpha14 natural killer T cells (NKT cells) and a subsequent reduction of NKT cells in the periphery. The remaining NKT cells failed to produce measurable quantities of interferon-gamma in vivo and in vitro after activation with alpha-galactosylceramide. In addition, thymocytes and splenocytes from NPC2-deficient mice were poor presenters of endogenous and exogenous lipids to CD1d-restricted Valpha14 hybridoma cells. Importantly, we determined that similar to saposins, recombinant NPC2 was able to unload lipids from and load lipids into CD1d. This transfer activity was associated with a dimeric form of NPC2, suggesting a unique mechanism of glycosphingolipid transfer by NPC2. Similar to saposin B, NPC2 dimers were able to load isoglobotrihexosylceramide (iGb3), the natural selecting ligand of NKT cells in the thymus, into CD1d. These observations strongly suggested that the phenotype observed in NPC2-deficient animals was directly linked to the efficiency of the loading of iGb3 into CD1d molecules expressed by thymocytes. This conclusion was supported by the rescue of endogenous and exogenous iGb3 presentation by recombinant NPC2. Thus, the loading of endogenous and exogenous lipids and glycolipids onto CD1d is dependent on various small, soluble lipid transfer proteins present in the lysosome.

Syllables and other String Kernel Extensions (2002)

Recently, the use of string kernels that compare documents as a string of letters has been shown to achieve good results on text classification problems. In this paper we introduce the application of the string kernel in conjunction with syllables. Using syllables shortens the representation of documents and as a result reduces computation time.
Video annotation based on temporally consistent Gaussian random field (2007)

A novel method for automatically annotating video semantics, called temporally consistent Gaussian random field (TCGRF) is proposed. Since the temporally adjacent video segments (e.g. shots) usually have a similar semantic concept, TCGRF adapts the temporal consistency property of video data into graph-based semi-supervised learning to improve the annotation results. Experiments conducted on the TRECVID data set have demonstrated its effectiveness.
Autoxidation of polyunsaturated fatty compounds in mackerel oil: Formation of 2,4,7‐decatrienals (1975)

Abstract The formation of potentially “fishy” off flavor components, especially 2,4,7‐decatrienals, in various rancid mackerel oils has been semiquantitatively investigated using preparative thin layer chromatography (TLC) and gas liquid chromatography (GLC) methods. A combination of 2 GLC analyses can be directly employed for free aldehyde analysis. This GLC method is faster and gives a better recovery than the alternative TLC proceeding through the dinitrophenylhydrazone derivatives of the carbonyl compounds. Kinetic relations between decatrienal formation and the degree of autoxidation of polyenoic fatty compounds present in mackerel oil are discussed. The decreases in major polyenoic fatty acids rancid oils, measured by the ratios urn:x-wiley:0003021x:equation:aocs0349-math-0001 or urn:x-wiley:0003021x:equation:aocs0349-math-0002 can be related to the formation of 2,4,7‐decatrienals and other unsaturated aldehydes.
Edge-carboxylated graphene nanosheets via ball milling (2012)

Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer (≤ 5 layers) GNs. These stable ECG (or GN) dispersions have been used for solution processing, coupled with thermal decarboxylation, to produce large-area GN films for many potential applications ranging from electronic materials to chemical catalysts. The electrical conductivity of a thermally decarboxylated ECG film was found to be as high as 1214 S/cm, which is superior to its GO counterparts. Ball milling can thus provide simple, but efficient and versatile, and eco-friendly (CO(2)-capturing) approaches to low-cost mass production of high-quality GNs for applications where GOs have been exploited and beyond.
Critical Points in Tumorigenesis: A Carcinogen‐Initiated Phase Transition Analyzed via Single‐Cell Proteomics (2016)

A kinetic, single-cell proteomic study of chemically induced carcinogenesis is interpreted by treating the single-cell data as fluctuations of an open system transitioning between different steady states. In analogy to a first-order transition, phase coexistence and the loss of degrees of freedom are observed. The transition is detected well before the appearance of the traditional biomarker of the carcinogenic transformation.
Convenient Synthesis of Benzoylecgonine Ethyl Ester, a Homolog of Cocaine (1992)

Transcriptional Repression of Human Hepatitis B Virus Genes by a bZIP Family Member, E4BP4 (1999)

Box alpha is an essential element of both the upstream regulatory sequence of the core promoter and the second enhancer, which positively regulate the transcription of human hepatitis B virus (HBV) genes. In this paper, we describe the cloning and characterization of a box alpha binding protein, E4BP4. E4BP4 is a bZIP type of transcription factor. Overexpression of E4BP4 represses the stimulating activity of box alpha in the upstream regulatory sequence of the core promoter and the second enhancer in differentiated human hepatoma cell lines. E4BP4 can also suppress the transcription of HBV genes and the production of HBV virions in a transient-transfection system that mimics the viral infection in vivo. Expression of an E4BP4 antisense transcript can, instead, elevate the transcription of the core promoter. A low abundance of E4BP4 protein and mRNA in differentiated human hepatoma cell lines is detected, and E4BP4 is not a major component of box alpha binding proteins in untransfected differentiated human hepatoma cell lines. C/EBPalpha and C/EBPbeta, in contrast, are major components of the box alpha binding activity present in nuclear extracts. E4BP4 has a stronger binding affinity towards box alpha than the endogenous box alpha binding activity present in nuclear extracts. Structure and function analysis of E4BP4 reveals that DNA binding activity is sufficient to confer the negative regulatory function of E4BP4. These results indicate that binding site occlusion is the mechanism whereby E4BP4 suppresses transcription in HBV.
Novel indirect-conversion transceiver architectures using phantom oscillators (2002)

An integratable transceiver architecture utilizing a new spread spectrum local oscillator technique is presented. In this type of transceiver architecture, the effects of two or more spread-spectrum oscillators combine to produce a desired "phantom" oscillator useful for frequency translation. The phantom oscillator technique is particularly applicable to the up-conversion and down-conversion paths in integrated transceivers, since spread-spectrum oscillator leakage does not create problematic DC offsets.
Evaluation of Anti-invasion Effect of Resveratrol and Related Methoxy Analogues on Human Hepatocarcinoma Cells (2010)

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and is also highly metastatic. Metastasis is considered to be the major cause of death in cancer patients. Resveratrol (3,5,4'-trihydroxystilbene) and related analogues have been reported as candidates to prevent cancer growth and invasion. The bioactivity of resveratrol-related analogues could be altered due to the presence and positioning of methoxy groups on the basic resveratrol chemical structure. This study investigated the effects and mechanism of action of resveratrol and its methoxy analogues on invasion of human hepatocarcinoma cells. The migratory and invasive abilities of phorbol 12-myristate 13-acetate (PMA)-treated HepG2 and PMA-untreated Hep3B cells were both reduced in a dose-dependent manner by treatment with resveratrol and 3,5,4'-trimethoxy-trans-stilbene (MR-3). Upon incubation of PMA-treated HepG2 cells with resveratrol (0-50 microM) or MR-3 (0-50 microM), the MMP-9 activity decreased but TIMP-1 protein increased in a dose-dependent manner. With resveratrol (0-50 microM) or MR-3 (0-1 microM) treatment on PMA-untreated Hep3B cells, both of the MMP-9 and MMP-2 activities decreased but TIMP-2 protein increased in a dose-dependent manner. These results suggest that resveratrol and its related methoxy analogue MR-3 might exert anti-invasive activity against hepatoma cells through regulation of MMP-2, MMP-9, TIMP-1, and TIMP-2. Further analysis with semiquantitative RT-PCR showed that the regulation of MMP-9 and TIMP-2 expressions by resveratrol and MR-3 in hepatoma cells may be on the transcriptional level but on the translational or post-translational level for TIMP-1.
Hybrid Modelling of the Sucrose Crystal Growth Rate (2001)

This paper deals with the development of the crystal growth rate model according to a novel modelling strategy. The method combines an artificial neural network (ANN) as an approximator of the growth rate with prior knowledge represented by the mass balance on sucrose crystals. This approach reduces the modelling effort since the ANN does not impose a priori parameterization of the growth rate expression. Moreover, the resultant greater flexibility of the model augurs large predictive capability under a wide range of operating conditions. The model was developed with industrial data collected from a 60 m3 batch evaporative crystallizer.
Effect of Auger recombination and leakage on the droop in InGaN/GaN quantum well LEDs (2014)

We investigate the effect of the epitaxial structure and the acceptor doping profile on the efficiency droop in InGaN/GaN LEDs by the physics based simulation of experimental internal quantum efficiency (IQE) characteristics. The device geometry is an integral part of our simulation approach. We demonstrate that even for single quantum well LEDs the droop depends critically on the acceptor doping profile. The Auger recombination was found to increase stronger than with the third power of the carrier density and has been found to dominate the droop in the roll over zone of the IQE. The fitted Auger coefficients are in the range of the values predicted by atomistic simulations.
Microstructural Studies of Texturized Vegetable Protein Products: Effects of Oil Addition and Transformation of Raw Materials in Various Sections of a Twin Screw Extruder (1987)

In high-temperature short- time extrusion cooking with a twin screw extruder , effects of oil addition to defatted soybean flour and microstructural transformation of full - fat soybean flour during cooking , were investigated by use of a light microscope. At levels up to 15% , soybean oil was distributed in the protein and carbohydrate matrix as small, spherical drops under the experimental conditions used in this study. However , oil contents above 15% significantly prevented formation of well-aligned fibrous structures in the extrudates . During extrusion cooking , the starting materials began to break down by shearing and kneading forces in the feed section but gross cellular structures remained up to the cooking zone. After being introduced into the cooking zone , protein and carbohydrate were plasticized and appeared to be stream-like . Passage through the breaker plate and long cooling die induced formation of a fiber-like extrudate.
Formaldehyde‐based whole‐mount in situ hybridization method for planarians (2009)

Whole-mount in situ hybridization (WISH) is a powerful tool for visualizing gene expression patterns in specific cell and tissue types. Each model organism presents its own unique set of challenges for achieving robust and reproducible staining with cellular resolution. Here, we describe a formaldehyde-based WISH method for the freshwater planarian Schmidtea mediterranea developed by systematically comparing and optimizing techniques for fixation, permeabilization, hybridization, and postprocessing. The new method gives robust, high-resolution labeling in fine anatomical detail, allows co-labeling with fluorescent probes, and is sufficiently sensitive to resolve the expression pattern of a microRNA in planarians. Our WISH methodology not only provides significant advancements over current protocols that make it a valuable asset for the planarian community, but should also find wide applicability in WISH methods used in other systems.
