Socialite: A Flexible Framework for Social Internet of Things (2015)

The Social Internet of Things is a new paradigm that merges the Internet of Things with Social Networks. We propose a paradigm for how to model interactions between devices and humans, and among devices themselves to support sharable value-added applications throughout the device life cycle (e.g., Configuration, operation, preventive diagnosis), as well as to achieve common goals and recommendations. To realize this paradigm we propose a novel architecture and implementation to enable new Internet of Things applications based on emerging types of social relationships. We develop the semantic models for the Social Internet of Things including device types and their capabilities, users and their relationships, and rules leveraging such models. We demonstrate our concept by building a real system called Socialite that integrates various devices from different manufacturers with different functional interfaces and explicitly represents the relationships among active participants (devices as well as users) in our system.
Purification and Characterization of the Voltage-Dependent Anion-Selective Channel Protein from Wheat Mitochondrial Membranes (1993)

An approximately 29-kD protein was purified from the membrane fraction of wheat (Triticum aestivum cv Dganit) mitochondria by the utilization of standard liquid chromatography techniques. The protein, designated MmP29 for mitochondrial membrane protein having a molecular mass of approximately 29 kD, exhibited cationic properties in a buffering solution, adjusted to pH 7.5. This positive charge enabled its passage through a diethylaminoethyl column, without interaction with the positively charged matrix. Subsequently, this protein was separated from the remaining polypeptides by a preferential elution from a hydroxylapatite/celite mixed column. Reconstituted liposomes containing this protein were characterized as being permeable to 8-amino-naphthalene 1,3,6-trisulfonic acid disodium salt (Mr 445) but non-permeable to dextran fluorescein (Mr 40,000). Additionally, MmP29 was inserted into planar phospholipid membranes, and anion-selective, voltage-dependent channels were demonstrated. All of the MmP29 properties mentioned highly resemble voltagedependent, anion-selective channel (VDAC) proteins, suggesting that MmP29 is the mitochondrial outer membrane VDAC protein of wheat.
A Dynamic Contingency Analysis Visualization Tool (2020)

This paper presents a web-browser based visualization tool for displaying extensive dynamic contingency outputs, generated by the Dynamic Contingency Analysis Tool (DCAT). DCAT is an open-platform and publicly available methodology to help develop applications aiming to improve the capabilities of power system planning engineers to assess impact and likelihood of extreme contingencies, and potential cascading events across the systems and interconnections. We have developed this DCAT Visualization Tool as a new feature to the DCAT package to afford a visual situational awareness environment that allows engineers to better comprehend, interpret, and analyze DCAT data and results and to more directly view behaviors and causes and effects against the topology of a power grid. A usability evaluation was conducted to support the effectiveness of this tool. The techniques developed are generic enough that can be readily adapted by other power system applications. This visualization tool represents a vital capability for power system engineers to quickly capture and comprehend critical information.
Constrained Filtering Method for MAV Attitude Determination (2006)

In this paper we introduce a novel attitude measurement algorithm that gives the Euler angles based on MEMS sensors including three rate gyros, three magnetometers and one accelerometer. Six elements of the direction cosine matrix are selected to compose a state vector. Only four elements are independent, because there exists two nonlinear constraints. They are introduced as virtual measurements in the Kalman filter. The filter can be improved by introducing heading differential speed signal. Bias of simulation results indicates that the Euler angles can be determined with standard deviations at 1-3 degree even during high dynamic maneuvers and long turns. Flight tests have been carried out in a miniature UAV, the Euler angles' in which the method is proved to be valid in high dynamic maneuver
Performance enhancement of single-phase switched-reluctance motor by DC link voltage boosting (1993)

A novel and simple DC link voltage boosting circuit is proposed to enhance the performance of inverters for single-phase switched-reluctance motors. It consists of only two additional components to the single-phase switched-reluctance motor inverter, namely a capacitor and a diode. Except for some increase in the voltage rating of the inverter components, no change to the inverter hardware is needed. The boost circuit provides many operational advantages. It generates a high boost voltage during the current pull-up and pull-down periods and hence decreases the current rise and fall times. The boost feature thus reduces the magnitude of the negative torque pulses, increases the mean motor output power and improves the efficiency of energy recovery. The paper presents the basic operating principle of the boost circuit, a method for the sizing of the boost capacitor and the results of time stepping simulations of a boosted single-phase switched-reluctance drive. The simulated and measured results presented correlate well
Spectral blue shift via intermolecular interactions in the B2 and B4 phases of a bent-shaped molecule (2010)

A set of precise measurements of UV-Vis absorption spectrum for the classical bent-shaped molecule, P-12-OPIMB, revealed that molecular exciton interactions exist even in the mesophases of this system, as manifested as an obvious and abrupt change in the positional and spectral shape at phase-transition points. Based on Kasha's molecular exciton model, we successfully conducted a quantitative analysis of the spectral shift and could determine the local structure of the B4 phase. To the best of our knowledge, such a spectroscopic analysis for the liquid crystals has not been connected with the local structure.
Macrophage colony-stimulating factor as a tumor marker for epithelial ovarian cancer. (1993)

Macrophage colony-stimulating factor is a marker for ovarian cancer. Determination of serum levels can be useful in detecting ovarian cancer, particularly in combination with CA 125.
Traffic flow forecasting based on grey neural network model (2004)

In this paper, a kind of grey neural network (abbreviate as GNN) is proposed which combines grey system theory with neural network, that is, the GNN model has been built by adding a grey layer before neural input layer and a white layer after neural output layer. Gray neural network can elaborate advantages of both grey model and neural network, and enhance further precision of forecasting. The GNN model is employed to forecast a real vehicle traffic flow of Jingshi highway with favor precision and result, which is firstly applied GNN to traffic flow forecasting. Evaluation method has been used for comparing the performance of forecasting techniques. The experiments show that the GNN model is outperformed GM model and neural network model, and traffic flow forecasting based on GNN is of validity and feasibility.
Thin-walled solenoid end effects (1977)

The magnetic field maximum for air-core solenoids commonly occurs at the inside turn on the mid-plane. For thin-walled solenoids, however, the magnetic field maximum occurs at the ends of the solenoid. To study this end effect, closed form expressions are derived for the axial and radial magnetic field components in the vicinity of the solenoid windings. Formulae for single and double layer solenoids are developed as perturbations on the field of a uniform current sheet solenoid. Formulae for the axial and radial load stresses are developed also.
Green growth of CdSe nanostructures for application in Schottky type solar cell (2013)

CdSe nanostructures were synthesized by using green chemical route as starch was used as capping agent. XRD, HR-TEM, SEAD, UV and PL studies were made for structural and optical properties of the prepared sample. Film morphology and the thickness measurement of n-CdSe were carried out with AFM analysis. I-V characteristics curve of this junction confirmed the formation of Schottky contact between silver (Ag) and CdSe nanostructures. Intrinsic and contact behaviors such as saturation current, barrier height, effective Richardson constant, electron affinity and ideality factor were calculated from the current-voltage characterization.
Polycaprolactone/oligomer compound scaffolds for cardiac tissue engineering (2013)

Abstract Polycaprolactone (PCL), a synthetic biocompatible and biodegradable polymer generally used as a scaffold material for tissue engineering applications. The high stiffness and hydrophobicity of the PCL fiber mesh does not provide significant cell attachment and proliferation in cardiac tissue engineering. Towards this goal, the study focused on a compound of PCL and oligomer hydrogel [Bisphenol A ethoxylated dimethacrylate (BPAEDMA)] processed into electrospun nanofibrous scaffolds. The composition, morphology and mechanical properties of the compound scaffolds, composed of varying ratios of PCL and hydrogel were characterized by scanning electron microscopy, infrared spectroscopy and dynamic mechanical analyzer. The elastic modulus of PCL/BPAEDMA nanofibrous scaffolds was shown to be varying the BPAEDMA weight fraction and was decreased by increasing the BPAEDMA weight fraction. Compound fiber meshes containing 75 wt % BPAEDMA oligomer hydrogel exhibited lower modulus (3.55 MPa) and contact angle of 25 o . Rabbit cardiac cells cultured for 10 days on these PCL/BPAEDMA compound nanofibrous scaffolds remained viable and expressed cardiac troponin and alpha‐actinin proteins for the normal functioning of myocardium. Cell adhesion and proliferations were significantly increased on compound fiber meshes containing 75 wt % BPAEDMA, when compared with other nanofibrous scaffolds. The results observed that the produced PCL/BPAEDMA compound nanofibrous scaffolds promote cell adhesion, proliferation and normal functioning of cardiac cells to clinically beneficial levels, relevant for cardiac tissue engineering. © 2013 Wiley Periodicals, Inc.

Multiple Grb2-Mediated Integrin-Stimulated Signaling Pathways to ERK2/Mitogen-Activated Protein Kinase: Summation of Both c-Src- and Focal Adhesion Kinase-Initiated Tyrosine Phosphorylation Events (1998)

Fibronectin receptor integrin-mediated cell adhesion triggers intracellular signaling events such as the activation of the Ras/mitogen-activated protein (MAP) kinase cascade. In this study, we show that the nonreceptor protein-tyrosine kinases (PTKs) c-Src and focal adhesion kinase (FAK) can be independently activated after fibronectin (FN) stimulation and that their combined activity promotes signaling to extracellular signal-regulated kinase 2 (ERK2)/MAP kinase through multiple pathways upstream of Ras. FN stimulation of NIH 3T3 fibroblasts promotes c-Src and FAK association in the Triton-insoluble cell fraction, and the time course of FN-stimulated ERK2 activation paralleled that of Grb2 binding to FAK at Tyr-925 and Grb2 binding to Shc. Cytochalasin D treatment of fibroblasts inhibited FN-induced FAK in vitro kinase activity and signaling to ERK2, but it only partially inhibited c-Src activation. Treatment of fibroblasts with protein kinase C inhibitors or with the PTK inhibitor herbimycin A or PP1 resulted in reduced Src PTK activity, no Grb2 binding to FAK, and lowered levels of ERK2 activation. FN-stimulated FAK PTK activity was not significantly affected by herbimycin A treatment and, under these conditions, FAK autophosphorylation promoted Shc binding to FAK. In vitro, FAK directly phosphorylated Shc Tyr-317 to promote Grb2 binding, and in vivo Grb2 binding to Shc was observed in herbimycin A-treated fibroblasts after FN stimulation. Interestingly, c-Src in vitro phosphorylation of Shc promoted Grb2 binding to both wild-type and Phe-317 Shc. In vivo, Phe-317 Shc was tyrosine phosphorylated after FN stimulation of human 293T cells and its expression did not inhibit signaling to ERK2. Surprisingly, expression of Phe-925 FAK with Phe-317 Shc also did not block signaling to ERK2, whereas FN-stimulated signaling to ERK2 was inhibited by coexpression of an SH3 domain-inactivated mutant of Grb2. Our studies show that FN receptor integrin signaling upstream of Ras and ERK2 does not follow a linear pathway but that, instead, multiple Grb2-mediated interactions with Shc, FAK, and perhaps other yet-to-be-determined phosphorylated targets represent parallel signaling pathways that cooperate to promote maximal ERK2 activation.
From the biology of the individual to the dynamics of the population: bridging the gap in fish early life studies (1997)

The mean properties of larval fish populations do not necessarily reflect the properties of the mean individual. For example, the change in mean length in a population with time may not reflect the average individual growth rate, since individual growth rates and survival probability are linked so that slow growing individuals suffer higher mortality. Hence, mean growth rate indicated from population data could be biased upwards. Factors which influence the magnitude and variability of individual growth rates can exert nonlinear effects on population survival. Two categories of process must be considered: first, the variability in exposure of the average individual as a consequence of individual variability in dispersal through a patchy environment; and second, the intrinsic variability between individuals expressed even under equal exposure conditions. These two aspects have been addressed independently, the first by lagrangian modelling of individual fish larvae linked to spatially resolved hydrodynamic models, and the second by strategic biological modelling. In this paper, progress towards the goal of individually based larval fish ecosystem models is reviewed, highlighting the space and time scales which may be important in such systems, and identifying the gaps in current knowledge of larval biology.

Effect of Visual Display Parameters on Driving Performance in a Virtual Environments Driving Simulator (1996)

In virtual environment applications, there is a tradeoff between the quality of the graphic image and the speed at which the application runs. In driving simulation, the content and quality of the visual image are particularly important, which suggests that there are limits to the degree they can be reduced. A virtual environments driving simulator was used to investigate the effects of visual display parameters on driver performance and perception. A road tracking study compared two display devices, two rendering algorithms, and three levels of road side delineation poles. Subjects drove the simulator through a series of road courses, and answered questionnaires designed to evaluate their perception of the realism of the simulator and the sense of immersion in the virtual environment. The results of the study confirm previous work on the beneficial effects of road side delineation poles on driving performance. They also suggest the importance of lag in the perception of driving performance and immersion, and the importance of shaded images in actual driving task performance.
Optical dispersion of the refractive index modulation in low Tg photorefractive polymers (1997)

We measure at different wavelengths the linear and nonlinear optical properties of a new chromophore for photorefractive applications by means of frequency-dependent ellipsometry experiments. We show that the optical dispersion of the refractive index modulation responsible for the high diffraction efficiency in low Tg polymers can be described by a two-level model.
Data assimilation in the presence of forecast bias (1998)

Abstract Statistical‐analysis methods are generally derived under the assumption that forecast errors are strictly random and zero in the mean. If the short‐term forecast, used as the background field in the statistical‐analysis equation, is in fact biased, so will the resulting analysis be biased. The only way to account properly for bias in a statistical analysis is to do so explicitly, by estimating the forecast bias and then correcting the forecast prior to analysis. We present a rigorous method for estimating forecast bias by means of data assimilation, based on an unbiased subset of the observing system. The result is a sequential bias estimation and correction algorithm, whose implementation involves existing components of operational statistical‐analysis systems. The algorithm is designed to perform on‐line, in the context of suboptimal data‐assimilation methods which are based on approximate information about forecast‐ and observation‐error covariances. The added computational cost of incorporating online bias estimation and correction into an operational system roughly amounts to one additional solution of the statistical‐analysis equation, for a limited number of observations. Off‐line forecast‐bias estimates based on previously produced assimilated‐data sets can be produced as well, using an existing analysis system. We show that our sequential bias estimation algorithm fits into a broader theoretical framework provided by the separate‐bias estimation approach of estimation theory. In this framework the bias parameters are defined rather generally and can be used to describe systematic model errors and observational bias as well. We illustrate the performance of the algorithm in a simulated data‐assimilation experiment with a one‐dimensional forced dissipative shallow‐water model. A climate error is introduced into the forecast model via topographic forcing. while random errors are generated by stochastic forcing. In this simple setting our algorithm is well able to estimate and correct the forecast bias caused by this systematic error, and the climate error in the assimilated‐data set is virtually eliminated as a result.
ChemInform Abstract: Characterization of Silica‐Supported Ru‐Ag and Ru‐Au Bimetallic Catalysts by Hydrogen Chemisorption and NMR of Adsorbed Hydrogen. (1990)

Abstract Both the techniques used to study Ru‐Ag and Ru‐Au SiO 2 ‐supported catalysts yield nearly the same capacity for H 2 chemisorption on both series of bimetallic catalysts.
Species-specific differences in chaperone interaction of human and mouse major histocompatibility complex class I molecules. (1995)

Previous studies have shown that immature mouse class I molecules transiently associate with a resident endoplasmic reticulum protein of 88 kD that has been proposed to act as a chaperone for class I assembly. Subsequently, this protein was demonstrated to be identical to calnexin and to associate with immature forms of the T cell receptor complex, immunoglobulin, and human class I HLA heavy chains. In this paper we define further the interaction of human class I HLA heavy chains with chaperone proteins and find key differences with the complexes observed in the mouse system. First, calnexin and immunoglobulin binding protein (BiP) both associate with immature HLA class I heavy chains. The two chaperones are not found within the same molecular complex, suggesting that calnexin and BiP do not interact simultaneously with the same HLA class I heavy chain. Second, only free HLA class I heavy chains, and not beta 2-microglobulin (beta 2m)-associated heavy chains are found associated with the chaperones. Indeed, addition of free beta 2m in vitro induces dissociation of chaperone-class I HLA heavy chain complexes. The kinetics for dissociation of the class I HLA heavy chain-chaperone complexes and for formation of the class I HLA heavy chain-beta 2m complex display a reciprocity that suggests the interactions with chaperone and beta 2m are mutually exclusive. Mouse class I heavy chains expressed in human cells exhibit the mouse pattern of interaction with human chaperones and human beta 2m and not the human pattern, showing the difference in behavior is purely a function of the class I heavy chain sequence.
Micro flow sensor based on two closely spaced amperometric sensors (2005)

In this communication, a novel micro flow sensor based on two closely spaced amperometric oxygen sensors is proposed and implemented. The simulation results show that the ratio of the responses of these two oxygen sensors is determined by flow rates in the micro-channel. The sensor has been implemented using a micro fabrication technique. The measurement results demonstrate that the technique is able to detect flow rates in the flow range of several microliters per minute when the distance between the working electrodes of two oxygen sensors is 10 microm and the cross-section of the micro-channel is 100 microm x 100 microm. The advantage of the proposed flow sensor is that no additional tracers have to be added or produced during the flow measurement. Information on dissolved oxygen concentration in the liquid is not required either.
Two-Dimensional Self-Assembled Structures of Melamine and Melem at the Aqueous Solution−Au(111) Interface (2010)

Self-assembled structures of melamine and the condensed melamine derivative melem were investigated at aqueous solution-Au(111) interfaces by cyclic voltammetry and in situ scanning tunneling microscopy (STM) observation. The adsorption/desorption behaviors of both molecules on Au(111) surfaces could be controlled by varying the electrochemical potential and solution concentration. In the negative potential region, self-assembled structures of melem and melamine were constructed by double hydrogen bonding systems between nitrogen atoms of triazine rings and amine groups. In addition, melem formed a closely packed structure at potentials of between -0.3 and -0.15 V or in solutions at higher concentrations.
