Dual-emitting quantum dot nanohybrid for imaging of latent fingerprints: simultaneous identification of individuals and traffic light-type visualization of TNT (2015)

Fingerprints are a unique characteristic of an individual. Recently, it has been realized that fingerprints carry more information about individuals than just their identity, for example, they may identify potential addicts and terrorists carrying explosives. Therefore, the development of imaging moieties capable of both fingerprint staining and drug/explosive visualization is of significant importance for forensic chemistry. Here we developed a nanohybrid comprising green- and red-emitting QDs for simultaneous fingerprint imaging and TNT visualization in fingerprints. The red-emitting Cu-doped ZnCdS (Cu-ZnCdS) QDs were embedded into silica nanoparticles and the green-emitting ZnCdS QDs were anchored onto the surface of the silica nanoparticles and further functionalized with polyallylamine (PAA). Both components of the nanohybrid, <i>i.e.</i>, the PAA-functionalized green QDs and red QD-doped silica nanoparticles, could be explored for fingerprint imaging. Due to the formation of a Meisenheimer complex between TNT and PAA, the green-emitting QDs could be quenched by TNT, meanwhile the red-emitting QDs were inert. Therefore, the nanohybrid exhibited a traffic light-type fluorescence color change (green-yellow-red) to TNT concentration in the range of 40-400 μM. This method is promising for potential applications in security-screening needs in public areas such as airports and train stations.
The variation in isometric tension with sarcomere length in vertebrate muscle fibres (1966)

1. The variation of isometric tetanus tension with sarcomere length in single fibres from frog striated muscle has been re-investigated with special precautions to ensure uniformity of sarcomere length within the part of the fibre being studied.2. In most respects the results of Ramsey & Street (1940) were confirmed, but (a) the peak of the curve was found to consist of a plateau between sarcomere lengths of 2.05 and 2.2 mu, (b) the decline of tension above this plateau is steeper than found by Ramsey & Street, and (c) the decline of tension below the plateau becomes suddenly steeper at a sarcomere length of about 1.67 mu.3. Many features of this length-tension relation are simply explained on the sliding-filament theory.4. It is concluded that, in the plateau and at greater lengths, the tension on each thin filament is made up of equal contributions from each bridge which it overlaps on adjacent thick filaments.5. Internal resistance to shortening is negligible in this range but becomes progressively more important with shortening below the plateau.
Modifying Randles Circuit for Analysis of Polyoxometalate Layer-by-Layer Films (2010)

Multilayer films with anionic phosphomolybidic acid (PMo(12)) clusters have been fabricated via the electrostatic layer-by-layer (LbL) method. The charged mass transport phenomena of these thin films have been studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) with [Fe(CN)(6)](3-/4-) and [Ru(NH(3))(6)](3+/2+) as the redox probes. By adding a film resistance and a film capacitance to the conventional Randles equivalent circuit, we can calculate the diffusion coefficient values that help understand the microscopic nature of the thin films. When the negatively charged probe [Fe(CN)(6)](3-/4-) was used, lower diffusion coefficients were obtained for multilayers deposited from higher ionic strength solutions. This relationship was less obvious when the positively charged probe [Ru(NH(3))(6)](3+/2+) was used, in which the electrostatic attraction between PMo(12) clusters and the probe ions complicates the mass-transfer process. It is believed that the addition of salt to dipping solutions increases the tortuosity of the films so the mass transport takes longer paths, inducing lower diffusion coefficients. Higher PMo(12) loading causes lower diffusion coefficients due to the polyoxometalate clusters blocking the paths for charged probe ions.
Cellular interactions in tissue factor expression by blood monocytes. (1995)

Tissue factor (TF) is the cellular receptor for factor VIIa. In complex with TF, factor VIIa initiates coagulation by activation of factor IX and factor X. TF is normally not in contact with blood, but is expressed on extravascular cells which forms a haemostatic envelope ready to activate coagulation when vascular integrity is disrupted. However, under pathological conditions monocytes, but probably not endothelial cells, are stimulated to express TF activity on the surface of the cells and may thereby trigger activation of blood coagulation. For several years we have observed some individuals (high responders) with a very high response to lipopolysaccharide (LPS) as judged by induction of TF activity in their monocytes in whole blood. This phenomenon has been shown to be mediated by a P-selectin dependent interaction between granulocytes, platelets and monocytes where the release of platelet factor 4 (PF4) plays an important role. It is concluded that cellular interactions play a central role in the expression of TF activity in circulating monocytes.

Illustrated by the case of Mitsubish IPM(Intelligent Power Module) PS21767,the paper establishes a relatively complete Simplified thermal model and then carried out the research of its working temperature field in the method of finite element analysis with the thermal analysis software ——Pro / Mechanica.According to the situation above,the article comes up with an optimization program about IPM thermal performance ——using needle-shaped radiators to achieve the rapid dissemination of its exterior heat.This essay also proposes a new package style,which is to encapsulate with mixed plastic resin and aluminum alloy.The thermal analysis shows that this kind of package style has a significant positive effect on IPM chip heat dissemination.
Clinical evaluation of scanning laser polarimetry: I Intraoperator reproducibility and design of a blood vessel removal algorithm (1998)

The intraoperator reproducibility of retardation values obtained with the scanning laser polarimeter is satisfactory for its use as a clinical tool. The use of a blood vessel removal algorithm improves the reproducibility of the measurements and also assists the clinician in the interpretation of the polar profiles. Furthermore, it allows the construction of normal database polar profiles, thereby enabling the identification, location and quantification of retinal nerve fibre layer damage in an "at risk" individual's polar profile.
Synthesis and processing of the three major envelope glycoproteins of Epstein-Barr virus (1983)

In pulse-chase experiments, the three major Epstein-Barr virus envelope glycoproteins, gp350/300, gp250/200, and gp85, were shown to be synthesized from separate precursors of 190,000, 160,000, and 83,000 daltons, respectively. These three pulse-labeled species were chased into the mature forms of the glycoproteins between 1 and 3 h after transfer to nonradioactive medium. Digestion of precursor forms with endo-beta-N-acetylglucosaminidase H (endo H) yielded polypeptides of 160,000, 120,000, and 75,000 daltons. Comparison of these results with those from experiments with tunicamycin, which specifically blocks N-linked glycosylation, indicated that some other post-translational modification(s), probably O-linked glycosylation, contributes about 100,000 and 60,000 daltons of apparent molecular mass to gp350/300 and gp250/200, respectively. Experiments with endo H showed that mature gp350/300 and gp250/200 contain complex-type (endo H-resistant) N-linked glycosyl chains, whereas gp85 contains both high-mannose (endo H-sensitive)- and complex-type oligosaccharides. In contrast to the results obtained with the three envelope glycoproteins, no precursor forms of the two unglycosylated protein, p160 (the major Epstein-Barr virus capsid antigen) and p140 (an envelope protein), were detected. The partial proteolytic maps of gp350/300 and gp250/200 were quite similar, suggesting that polypeptide sequence homology could account for at least part of the observed serological cross-reactivity of the two proteins. Taken together, these results demonstrate that the polypeptide portions of gp350/300 and gp250/200 are closely related but not derived from a common precursor. Furthermore, the polypeptide portions comprise half or less of the apparent molecular weight of the mature glycoproteins on sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
Natural Language Processing for Automated Evaluation of Student Writing (2004)

There is an increased use of educational applications based on natural language processing for both largescale assessment and classroom instruction. This has occurred for two primary reasons. First, there has been a significant increase in the availability of computers in schools. Second, there has been notable development in computer-based educational applications that incorporate advanced methods in natural language processing that can be used to evaluate students’ work. Applications that automate the evaluation of essays use text-based NLP techniques that employ feature extraction and statistical machine learning. Such applications are commercially available, and are being used internationally by thousands of students. We will discuss these writing evaluation capabilities in the context of a deployed application, Criterion SM Online Essay Evaluation Service. Criterion has two complementary applications. The first, e-rater, is an automated essay scoring system. The second, Critique Writing Analysis Tools, is a suite of programs that detect errors in grammar, usage, and mechanics, The two applications identify discourse elements in the essay and recognize elements of undesirable style.
Identification of Wiener-Hammerstein models using linear interpolation in the frequency domain (LIFRED) (2002)

A new method to identify the linear subsystems of a Wiener-Hammerstein model through the measurement of the second-order Volterra kernel is proposed. This technique makes use of the symmetry properties of the Volterra kernel and assumes that the frequency response gain and phase between estimated points can be reasonably well approximated by a straight line. The signal applied for the identification is a multisine with properties of no interharmonic distortion. Several advantages of the proposed method over existing ones are discussed, and two simulation examples are presented to illustrate the applicability of the technique. The method is also shown to be robust to noise and distortion in the input signal.
abaA controls phialide differentiation in Aspergillus nidulans. (1990)

Aspergillus nidulans is an ascomycetous fungus that reproduces asexually by forming multicellular conidiophores and uninucleate spores called conidia. Loss of function mutations in the abacus A (abaA) regulatory locus result in formation of aberrant conidiophores that fail to produce conidia. Wild-type conidiophores form two tiers of sterigmata. The first tier, metulae, divide to produce the second tier, phialides. Phialides are sporogenous cells that produce conidia through a specialized apical budding process. We have examined conidiophore development in an abaA- strain at the ultrastructural level. The results showed that in the mutant metulae produce supernumerary tiers of cells with metula-like, rather than phialide-like, properties. Temperature shift experiments with an abaA14ts strain demonstrated that abaA+ function induced phialide formation by the aberrant abacus cells and was continuously required for maintenance of phialide function. In the absence of abaA+ activity, metulae simply proliferated and later developmental steps never occurred. We conclude that abaA+ directs the differentiation of phialides and is continuously required for maintenance of their function.
Restriction Endonuclease Analysis of the Genome of Campylobacter pylori with a Rapid Extraction Method: Evidence for Considerable Genomic Variation (1988)

We developed a rapid extraction method to analyze the chromosomal DNA of 84 isolates of Campylobacter pylori (formerly Campylobacter pyloridis) from 70 individuals. Only three of the nine endonucleases tested gave satisfactory digestions: HindIII, EcoRI, and SacI. The latter two produced mostly larger bands, whereas HindIII produced smaller bands, which allowed clearer comparisons between isolates. The isolates from 69 Australian subjects and one from England each had a unique profile. Isolates from a husband and wife were different, as were those from a brother and sister. In pairs of isolates from 11 individuals, the second isolate was markedly different in six subjects. The profile changes were not associated with changes in antibiotic susceptibility or with loss of catalase or urease activity, which can occur during storage of C. pylori. These restriction endonuclease profiles suggest considerable subspecies variation in C. pylori. Plasmid bands were found in undigested DNA from 40 of the 84 C. pylori isolates.
Linear relationship of damping ratios in resonance‐type fatigue testing of a wind turbine blade (2013)

ABSTRACT Damping ratios during resonance‐type fatigue testing of a 44 m wind turbine blade were found with respect to six different test setups. Based on a suggested parameter, six different lines of damping ratios at different test setups were linearized into a single line. Using the line, damping ratios at other plausible test setups can be predicted. Copyright © 2013 John Wiley & Sons, Ltd.

Algorithmic Labor and Information Asymmetries: A Case Study of Uber’s Drivers (2016)

Uber manages a large, disaggregated workforce through its ridehail platform, one that delivers a relatively standardized experience to passengers while simultaneously promoting its drivers as entrepreneurs whose work is characterized by freedom, flexibility, and independence. Through a nine-month empirical study of Uber driver experiences, we found that Uber does leverage significant indirect control over how drivers do their jobs. Our conclusions are twofold: First, the information and power asymmetries produced by the Uber application are fundamental to its ability to structure control over its workers; second, the rhetorical invocations of digital technology and algorithms are used to structure asymmetric corporate relationships to labor, which favor the former. Our study of the Uber driver experience points to the need for greater attention to the role of platform disintermediation in shaping power relations and communications between employers and workers.
Hybrid power generation system for aircraft electrical emergency network (2011)

A whole structure and two management strategies are proposed here for hybridisation of a Ram air turbine (RAT) by means of supercapacitors. Such hybrid structure is dedicated to an aircraft emergency network. The structure consists in coupling, through a 270 V DC bus, a controlled source (RAT) with a storage device interfaced through a bidirectional DC–DC converter. Both the energy-management strategies are described and analysed: the first one is to assign the ‘high-frequency harmonics’ of the load power to the storage which is current controlled, whereas the RAT controls the bus voltage and then only feeds the average power, losses and low-frequency harmonics of the load. The second one proposes an energy optimised operation of the system: the RAT, being current controlled, is able to maximise the supplied power (maximum power point tracking), as for classical wind turbines. For such a strategy, the bus voltage is regulated from the storage device. The RAT sizing and its mass can then be strongly reduced by means of this hybrid structure controlled with optimised management strategies. Experiments on a lab test-bench confirm analyses presented.
Credibility Evidence for Computational Patient Models Used in the Development of Physiological Closed-Loop Controlled Devices for Critical Care Medicine (2019)

Physiological closed-loop controlled medical devices automatically adjust therapy delivered to a patient to adjust a measured physiological variable. In critical care scenarios, these types of devices could automate, for example, fluid resuscitation, drug delivery, mechanical ventilation, and/or anesthesia and sedation. Evidence from simulations using computational models of physiological systems can play a crucial role in the development of physiological closed-loop controlled devices; but the utility of this evidence will depend on the credibility of the computational model used. Computational models of physiological systems can be complex with numerous non-linearities, time-varying properties, and unknown parameters, which leads to challenges in model assessment. Given the wide range of potential uses of computational patient models in the design and evaluation of physiological closed-loop controlled systems, and the varying risks associated with the diverse uses, the specific model as well as the necessary evidence to make a model credible for a use case may vary. In this review, we examine the various uses of computational patient models in the design and evaluation of critical care physiological closed-loop controlled systems (e.g., hemodynamic stability, mechanical ventilation, anesthetic delivery) as well as the types of evidence (e.g., verification, validation, and uncertainty quantification activities) presented to support the model for that use. We then examine and discuss how a credibility assessment framework (American Society of Mechanical Engineers Verification and Validation Subcommittee, V&V 40 Verification and Validation in Computational Modeling of Medical Devices) for medical devices can be applied to computational patient models used to test physiological closed-loop controlled systems.

Multiple Dipole Modeling and Localization from (1992)

An array of biomagnetometers may be used to measure the spatio-temporal neuromagnetic field or magne- toencephalogram (MEG) produced by neural activity in the brain. A popular model for the neural activity produced in re- sponse to a given sensory stimulus is a set of current dipoles, where each dipole represents the primary current associated with the combined activation of a large numer of neurons lo- cated in a small volume of the brain. An important problem in the interpretation of MEG data from evoked response experi- ments is the localization of these neural current dipoles. We present here a linear algebraic framework for three common spatio-temporal dipole models: i) unconstrained dipoles, ii) di- poles with a fixed location, and iii) dipoles with a fixed orien- tation and location. In all cases, we assume that the location, orientation, and magnitude of the dipoles are unknown. With a common model, we show how the parameter estimation prob- lem may be decomposed into the estimation of the time invari- ant parameters using nonlinear least-squares minimization, followed by linear estimation of the associated time varying pa- rameters. A subspace formulation is presented and used to de- rive a suboptimal least-squares subspace scanning method. The resulting algorithm is a special case of the well-known Multiple SIgnal Classification (MUSIC) method, in which the solution (multiple dipole locations) is found by scanning potential loca- tions using a simple one dipole model. Principal components analysis (PCA) dipole fitting has also been used to individually fit single dipoles in a multiple dipole problem. Analysis is pre- sented here to show why PCA dipole fitting will fail in general, whereas the subspace method presented here will generally suc- ceed. Numerically efficient means of calculating the cost func- tions are presented, and problems of model order selection and missing moments are discussed. Results from a simulation and a somatosensory experiment are presented.
Studies of an Inhibitor of the Two Antibody Immunoassay System (1964)

A heat labile plasma inhibitor of the two antibody insulin immunoassay system has been investigated by means of paper electrophoresis, ultracentrifugation, and DEAE cellulose anion exchange resin. These studies indicate that the inhibitor does not interfere with the binding of insulin to its specific antibody (first antibody reaction); but that the inhibitor interferes with the reaction of anti-guinea pig serum (rabbit source) with the insulin-anti-insulin soluble complex (second antibody reaction). When plasma samples are appropriately diluted the effect of the inhibitor is minimized.
Lysine: arginine ratio of a protein influences cholesterol metabolism. Part 1--Studies on sesame protein having low lysine: arginine ratio. (1997)

The effect of globulin fraction with a lysine: arginine (lys:arg) ratio 0.67, isolated from sesame (Sesamum Indicum) seeds on cholesterol metabolism was studied in rats fed cholesterol free and cholesterol containing diet and compared with casein (lys:arg ratio-2.0). Rats fed sesame seed globulin showed significantly lower concentrations of cholesterol in the serum and aorta. The decrease in serum was manifested in both HDL and LDL + VLDL fractions. There was increased cholesterogenesis in the liver as was evident from increased incorporation of labeled acetate into cholesterol and increased activity of 3-Hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase. Increased hepatic diversion of cholesterol to bile acid synthesis and increased fecal excretion of bile acids and sterols were also observed in rats fed sesame seed globulins. Rats fed sesame globulins also showed significantly higher activity of lipoprotein lipase in the heart and adipose tissue and that of plasma Lecithin: cholesterol acyltransferase (LCAT). These studies suggest that low lysine: arginine ratios of a protein exert hypocholesterolemic effects.
Multiple Description Video Coding Algorithm Based on Scalar Quantization (2011)

The principles of multiple description coding are introduced in this paper,and multiple description video coding algorithm based on scalar quantization(MDVSQ) is presented.In this method,two rough-quantitative versions of source video stream,which are not totally different,are yielded and transmitted after encoding respectively.Joint decoding is performed by taking advantage of the redundant information of the two versions.The simulation results show that the PSNR of reconstructed image in MDVSQ is obviously higher than traditional video coding at high packet loss rate.
