Enhancing the Robustness of Aeroelastic Instability Suppression Using Multi-Degree-of-Freedom Nonlinear Energy Sinks (2008)

In this last of a three paper sequence, we use simultaneous multimodal broadband targeted energy transfers to multi-degree-of-freedom nonlinear energy sinks to improve the robustness of aeroelastic instability suppression of a rigid wing with structural nonlinearities. A numerical bifurcation analysis of limit cycle oscillations of the wing with the multi-degree-of-freedom nonlinear energy sinks attached shows that controlling the lower parameter value for limit point cycle bifurcation to occur above Hopf bifurcation is crucial to enhancing the robustness of limit cycle oscillation suppression. We demonstrate that multi-degree-of-freedom nonlinear energy sinks can greatly enhance the robustness of limit cycle oscillation suppression, compared with single-degree-of-freedom nonlinear energy sinks (which were studied in our previous papers), with a much smaller total mass. We also investigate the nonlinear modal interactions that occur between the aeroelastic modes and the multi-degree-of-freedom nonlinear energy sinks, in an effort to gain a physical understanding of the mechanisms governing instability suppression. We demonstrate that a properly designed multi-degree-of-freedom nonlinear energy sink provides robustness of aeroelastic instability suppression by efficiently, passively, and rapidly transferring a significant portion of unwanted vibration energy to the furthest mass of the nonlinear energy sink. Consideration of other types of multi-degree-of-freedom nonlinear energy sinks suggests that the robustness enhancement is achieved by the concentrated mass effect of the attached nonlinear energy sinks.

Paths and Contextually Specific Recommendation. (2001)

We describe the Recer system and its underlying model of user activity, paths. A path is a timestamped log of activity in one of more tools, such as web browsers and text editors, gained by client–side tracking. By default, recent user activity is taken as representing the current context, and as an implicit query to the database of paths. The result is a set of recommendations specific to that context, and also reflecting a group’s patterns of past activity with the logged tools. We give some examples of its use before going on to discuss how recommender systems’ ability to handle heterogeneous data types allows extension of the model of user context to include locations and artefacts in both the physical world and virtual worlds. Our aim here is to have a much more realistic and broad notion of context and activity implemented in our systems, moving beyond an implicit assumption that all that is significant about a person’s activity is on their desktop. We outline our current work extending Recer to track multiple devices and media so that recommendations refer to people, places and things—both physical and digital. Recer will become part of a larger system aiming to support awareness and collaboration amongst people exploring a collection of documents about Glasgow, the physical city and a VR model of the city centre.
An investigation of Si-SiO2 interface charges in thermally oxidized (100), (110), (111), and (511) silicon (1990)

Trends in the electronic properties of the Si-SiO2 interface with various processing have been frequently reported. The present study focuses on silicon substrate orientation dependent trends in fixed oxide charge, Qf, and interface trap charge, Dit, for four silicon orientations: (100), (110), (111), and (511), for oxidation temperatures in the 750–1100 °C range, with and without hydrogen-containing post-metal anneals, and for processing within and without a cleanroom. It is found that the presence of mobile ionic charge in non-cleanroom processing and the lack of post-metal annealing can either obscure or enhance some trends. Both Qf and Dit increase for decreasing oxidation temperature for all silicon orientations. The orientational ordering of the charges varies with oxidation temperature and is dominated by the silicon atom areal density at the lowest temperatures with (110) Si having the highest charge, but a change to the (111) orientation is observed at higher oxidation temperatures. This orientational charge ordering parallels the orientational oxidation rate ordering but not the intrinsic stress. A model is proposed that considers the orientationally dominated oxidation rate, viscous relaxation, and strain accommodation across the interface as crucial processes.

TS‐SLS (Two‐Shot Sequential Lateral Solidification) technique has been employed to improve the TFT characteristics. Thanks to the superb characteristics of the TS‐SLS TFTs, 1:6 de‐multiplexing driving scheme has been successfully implemented in the source driver, which resulted very compact circuit area and the highest resolution (200ppi) SOG (System on Glass) display ever reported.
Herpes simplex viruses with mutations in the gene encoding ICP0 are defective in gene expression (1992)

Herpes simplex virus type 1 (HSV-1) mutants with codon insertions and deletions in IE-0, the gene encoding ICP0, were constructed. The HSV-1 deletion mutant dl1403 (N. D. Stow and E. C. Stow, J. Gen. Virol. 67:2571-2585, 1986) and an IE-0:lacZ transplacement vector isolated in this study were used to facilitate the construction of mutant viruses. Mutant viruses, all of which produced stable ICP0, were examined for their ability to plaque and grow on both Vero and HeLa cells because previous results showed that HSV-1 immediate-early (IE) gene promoters and their products are differentially expressed in these cells (J. Chen, X. Zhu, and S. Silverstein, Virology 180:207-220, 1991; I. H. Gelman and S. Silverstein, J. Virol. 61:2286-2296, 1987). Viruses with IE-0 genes that only poorly activated reporter genes in transient expression assays plaqued less efficiently on Vero cells and consistently accumulated decreased levels of late proteins. These mutants were also examined in single-step growth curve experiments and for the dependence of virus yield on multiplicity of infection (MOI). At low MOIs, their yields were less in Vero cells than in HeLa cells; by contrast, at high MOIs, there was no apparent difference in yield in either cell type, although each virus produced considerably fewer progeny than wild-type virus. Analysis of steady-state levels of RNA from genes representing each of the three major kinetic classes demonstrated that lower levels of RNAs accumulate in these mutants. We conclude from these studies that while ICP0 is not essential for virus growth in tissue culture, defects in this gene result in impairment of virus replication and delay the expression of early and late gene transcripts.

A Combined Wavelet and Data-Mining Based Intelligent Protection Scheme for Microgrid (2015)

This paper presents an intelligent protection scheme for microgrid using combined wavelet transform and decision tree. The process starts at retrieving current signals at the relaying point and preprocessing through wavelet transform to derive effective features such as change in energy, entropy, and standard deviation using wavelet coefficients. Once the features are extracted against faulted and unfaulted situations for each-phase, the data set is built to train the decision tree (DT), which is validated on the unseen data set for fault detection in the microgrid. Further, the fault classification task is carried out by including the wavelet based features derived from sequence components along with the features derived from the current signals. The new data set is used to build the DT for fault detection and classification. Both the DTs are extensively tested on a large data set of 3860 samples and the test results indicate that the proposed relaying scheme can effectively protect the microgrid against faulty situations, including wide variations in operating conditions.
Effect of somatostatin-induced suppression of postprandial insulin response upon the hypertriglyceridemia associated with a high carbohydrate diet. (1982)

In an attempt to define the relationship between plasma insulin and triglyceride concentrations, we have studied the effect of suppression of the postprandial insulin response upon the secretion and plasma concentration of very low density lipoprotein (VLDL)-triglycerides. Eight nondiabetic subjects with a wide range of fasting plasma triglyceride levels (100-358 mg/dl) were studied during three dietary periods: base line, high carbohydrate (80% calories), and high carbohydrate (80% calories) with a daily intravenous infusion of somatostatin (SRIF) (1.3 micrograms/min) between 800 and 2,100 h. The significant increase in postprandial insulin response observed during high carbohydrate vs. base line was completely abolished during high carbohydrate-SRIF. However, plasma triglyceride levels rose in all subjects during each high carbohydrate period (with/without SRIF) vs. base line and the mean values reached during each period were the same (476 +/- 165 vs. 482 +/- 152 mg/dl, respectively). The secretion of VLDL-triglyceride into plasma was higher in four subjects, the same in two subjects, and lower in one subject during high carbohydrate-SRIF vs. high carbohydrate alone. The mean production rate of VLDL-triglyceride (mg/kg per h) was 25.6 +/- 4.9 during the high carbohydrate and 40.9 +/- 28.1 during the high carbohydrate-SRIF periods. These values were not significantly different. Postprandial glucose levels were slightly increased during high carbohydrate-SRIF, but overnight glucose concentrations were not affected. Plasma FFA levels were not different during the two high carbohydrate periods. Plasma glucagon levels did not appear to affect the results either. This study indicates that postprandial hyperinsulinemia during a high carbohydrate diet is not necessary for induction of hypertriglyceridemia.
Incremental Methods for Simple Problems in Time Series: Algorithms and Experiments (2006)

A time series (or equivalently a data stream) consists of data arriving in time order. Single or multiple data streams arise in fields including physics, finance, medicine, and music, to name a few. Often the data comes from sensors (in physics and medicine for example) whose data rates continue to improve dramatically as sensor technology improves and as the number of sensors increases. So fast algorithms become ever more critical in order to distill knowledge from the data. This paper presents our recent work regarding the incremental computation of various primitives: windowed correlation, matching pursuit, sparse null space discovery and elastic burst detection. The incremental idea reflects the fact that recent data is more important than older data. Our StatStream system contains an implementation of these algorithms, permitting us to do empirical studies on both simulated and real data.

A 13.5-MHz relaxation oscillator with ±0.5% temperature stability for RFID application (2016)

This paper presents a 13.5-MHz low-power, RC on-chip relaxation oscillator with split-capacitor technique for RFID application. This oscillator implements only one comparator and one reference voltage to minimize power consumption and silicon area. A loop delay variation cancellation technique that employs an integrator loop and a split-capacitor architecture helps attained the temperature stability in the proposed oscillator. The proposed design is fabricated in 0.18-μm CMOS process. The relaxation oscillator consumes 48.8 μW at 1.8-V power supply. The measurement results show that the circuit can generate a stable frequency of 13.5 MHz. The output frequency variation is less than ±0.5% of temperature range from -30° C to 120° C, and the supply voltage variation coefficient is 0.5%/V across 1.5 V to 2.1V supply voltage.
Induction of resistance to fluorodeoxyuridine cytotoxicity and DNA damage in human tumor cells by expression of Escherichia coli deoxyuridinetriphosphatase. (1994)

Recent studies from our laboratory suggested that, in some human colorectal tumor cell lines, sensitivity to fluorodeoxyuridine may depend upon the extent of dUTP accumulation that occurs following drug treatment and that elevation of dUTPase activity might be the basis for some instances of resistance to fluoropyrimidines. To test this model, we expressed Escherichia coli dUTPase in an established human tumor cell line (HT29) and measured the effect of this manipulation on response to fluorodeoxyuridine. As predicted, HT29 derivatives containing dUTPase activity 4-5-fold higher than controls were protected from fluorodeoxyuridine-induced loss of clonogenicity and from formation of DNA double strand breaks. These data provide the first direct evidence that alteration in a component of the uracil misincorporation/misrepair pathway can confer resistance to fluoropyrimidines in human tumor cells.
A low frequency electrical earth model (1955)

Abstract A general earth model is described which simulates the earth when excited by currents either conductively coupled to the earth by electrodes or inductively coupled to the earth by loops. Consideration of model equations showed that a material with a resistivity of approximately 10 (super -4) ohm-meters was desired for use in the model. Although suitable materials with this resistivity were not known, it was found that fine bronze wheel grindings held together by wax did have the required macroscopic resistivity. Using this model, surface measurements were made employing a modified Wenner spread 'one mile' in length. Only minor anomalies resulted from a simulated salt dome 'three-quarters of a mile' in diameter and 'one-half mile' below the surface.
Seamless internetworking of WLANs and cellular networks: architecture and performance issues in a mobile IPv6 scenario (2005)

We review the problem of network mobility and internetworking between heterogeneous data networks and present an approach to the integration of WLAN and cellular networks based on loose coupling and the use of emerging mobility protocols. The handoff performance of such an approach is studied, at the network and transport levels, in a realistic scenario along with the impact on global performance of transport protocols. Finally, a method of eliminating any packet loss at the network layer during handoff is presented and evaluated.
Methodological aspects of Staphylococcus aureus peptidoglycan serology: comparisons between solid-phase radioimmunoassay and enzyme-linked immunosorbent assay (1984)

In the present studies we compared the ability of two commonly used assays, solid-phase radioimmunoassay and enzyme-linked immunosorbent assay (ELISA), to detect human antibodies to Staphylococcus aureus peptidoglycan. ELISA was superior, with a reproducibility of 12.0%, as compared with 18.1% in solid-phase radioimmunoassay. Much lower serum dilutions could be used in ELISA. We also studied the effects of solubilizing the antigen by lysostaphin, lysozyme, or ultrasonication. Lysostaphin-treated peptidoglycan cannot be recommended since solid-phase radioimmunoassay could not distinguish positive from negative serum samples with this preparation. On the other hand, the sensitivity in both assays was high when peptidoglycan treated with lysozyme for 240 min or with ultrasonication for 30 min was used as antigen. The interassay correlation between solid-phase radioimmunoassay and ELISA was slightly better with sonicated peptidoglycan (correlation coefficient = 0.94, P less than 0.01), as compared with lysozyme-treated peptidoglycan (correlation coefficient = 0.76, P less than 0.01). We recommend the ELISA with sonicated peptidoglycan as antigen for use in routine serology.
Antiangiogenic effects of latent antithrombin through perturbed cell-matrix interactions and apoptosis of endothelial cells. (2000)

Antithrombin is a plasma protein of the serpin superfamily that may occur as several conformational variants. The native form of antithrombin is a major regulator of blood clotting. In the present study, we have identified the mechanism underlying the antiangiogenic action of a heat-denatured form, denoted latent antithrombin. Fibroblast growth factor (FGF)-induced angiogenesis in the chick embryo and angiogenesis in mouse fibrosarcoma tumors were inhibited by treatment with latent antithrombin at 1 mg/kg/day. Thermolysin-cleaved and native antithrombin were less efficient in these respects. Treatment with latent antithrombin induced apoptosis of cultured endothelial cells and inhibited cell migration toward FGF-2. Under these conditions, FGF-2-stimulated FGF receptor kinase activity was unaffected. However, actin reorganization, activation of focal adhesion kinase, and focal adhesion formation were disturbed by latent antithrombin treatment of FGF-2-stimulated endothelial cells. These data indicate that latent antithrombin induces apoptosis of endothelial cells by disrupting cell-matrix interactions through uncoupling of focal adhesion kinase.
Isolation of human cytomegalovirus intranuclear capsids, characterization of their protein constituents, and demonstration that the B-capsid assembly protein is also abundant in noninfectious enveloped particles (1985)

Two types of intranuclear capsids have been recovered from human cytomegalovirus (HCMV, strain AD169)-infected cells. By analogy with strain Colburn (simian CMV) particles, these have been designated as A- and B-capsids. Both types of capsids are composed of proteins with molecular weights of 153,000 (major capsid protein), 34,000 (minor capsid protein), 28,000, and 11,000 (smallest capsid protein). In addition to these species, B-capsids contain a 36,000-molecular-weight (36K) protein which has been designated as the HCMV "assembly protein," based on its similarities to counterparts in strain Colburn CMV (i.e., 37K protein) and herpes simplex virus (i.e., VP22a/p40/NC-3/ICP35e). Peptide comparisons established that the assembly protein of HCMV B-capsids and the 36K protein that distinguishes HCMV noninfectious enveloped particles from virions are the same, providing direct evidence that noninfectious enveloped particles are enveloped B-capsids.
Changes in Ischemic Tolerance and Effects of Ischemic Preconditioning in Middle-aged Rat Hearts (1997)

These results indicate that hearts became more vulnerable to ischemia with age and that the beneficial effects of preconditioning were reversed in middle-aged rat hearts.
Design and testing of a microfluidic biochip for cytokine enzyme-linked immunosorbent assay (2009)

Enzyme-linked immunosorbent assay (ELISA) has been widely used in medical diagnostics, environmental analyses, and biochemical studies. To reduce assay time and lower consumption of reagents in cytokine ELISA analysis, a polymeric microfluidic biochip has been designed and fabricated via several new techniques: Polyaniline-based surface modification for superhydrophobic capillary valving and oxygen plasma-poly(ethyleneimine)-tyrosinase-protein A modification for high sensitivity protein detection. The proper flow sequencing was achieved using the superhydrophobic capillary valves. The burst frequency of each valve was experimentally determined and compared with two capillary force equations and the fluent finite element simulation. This fully automated microfluidic biochip with an analyzer is able to provide high fluorescence signal of ELISA with a wider linear detection range and a much shorter assay time than 96-well microtiter plates. It is applicable to a variety of nonclinic research and clinically relevant disease conditions. The modification technologies in this study can be implemented in other lab-on-a-chip systems, druggene delivery carriers, and other immunoassay biosensor applications.
Extracellular polysaccharide production by <i>Klebsiella pneumoniae</i> and its relationship to virulence (1985)

Klebsiella pneumoniae serotype 1 and serotype 2 and their capsular variants were examined for production of cell-associated capsular polysaccharides and extracellular capsular polysaccharides. The virulence of these organisms in experimental animals was examined via intraperitoneal injection in mice and transtracheal inoculation into the lungs of rats. It was found that the production of either polysaccharide component correlated with the observed virulence. The extracellular polysaccharides were purified by ethanol precipitation, electrodialysis, extraction with quaternary ammonium salts, and gel filtration. These purification steps allowed for the separation and purification of both the extracellular lipopolysaccharide and the extracellular capsular polysaccharide. Purified extracellular capsular polysaccharide and extracellular lipopolysaccharide were co-injected with K. pneumoniae intraperitoneally into mice to determine if either of these substances would produce an effect on the natural course of infection in these animals. These studies showed that only purified extracellular lipopolysaccharide enhanced the virulence of K. pneumoniae when co-injected into mice, and this virulence enhancement correlated with the content of extracellular lipopolysaccharide, but not extracellular capsular polysaccharide in mixtures of these polysaccharides. Saponification of K. pneumoniae serotype 1 extracellular polysaccharides significantly decreased their virulence-enhancing capabilities in mice, further suggesting that extracellular lipopolysaccharide may play a role in these infections.
