[Electron microscopic demonstration of viruses in feces of dogs with diarrhea]. (1995)

4044 stool samples of dogs with diarrhoea were examined by electron microscopy. The samples were sent for routine diagnostics in the years 1988-1993. Over the examination period virus was detected in 32% of the samples. Parvovirus was diagnosed in 17.2% and coronavirus in 12.4% of the cases. The number of parvovirus-positive samples was lower than in former years, whereas the number of coronavirus-positive samples was higher. Other virus particles (paramyxo-, picorna-, calici- and astrovirus or morphologically similar particles as well as rota- and adenovirus) were altogether detected in 2.5% of the samples. This detection rate corresponded to the results of former years. The majority of parvovirus-positive samples (80.7%) was found in animals aged between six weeks and six months. Of the coronavirus-positive samples 56.5% were detected in dogs older than six months of age and 42.5% in animals between six weeks and six months. In puppies up to six weeks viruses were only detected infrequently (parvovirus 4.7%, coronavirus 0.9%).
Force Ripple Compensation in Linear Motors Based on Closed-Loop Position-Dependent Identification (2009)

Permanent-magnet linear synchronous motors can serve as direct-drive actuators for machine tools and production machines, whenever high dynamic performance are required. Since compliance in transmission elements is eliminated, higher control bandwidths can be achieved, when compared to traditional solutions based on conversion from rotational to linear motion. Like their rotational counterparts, these motors are, however, affected by a ripple, in the form of parasitic and undesired force pulsations. In this paper, a compensation scheme of force ripple is proposed, based on a simple and compact model of the disturbance. The compensation requires a preliminary identification stage that simply consists of a couple of controlled motions at constant and very low velocity. The compensation term is then applied in parallel to the position/velocity controller, as a function of the linear position of the motor. A robustness analysis is performed based on a convenient formulation of the closed-loop system, as well as on a Lyapunov argument. Experiments that demonstrate the effectiveness of the method are reported, even when compared to a traditional force disturbance observer.
Feasibility of Reflectometry for Nondestructive Evaluation of Prestressed Concrete Anchors (2009)

Concrete dams and other large civil structures utilize steel cable anchors to improve strength and stability. Reflectometry methods that have been used for location of faults in electrical systems are examined as a possible method for location and quantization of possible deterioration on concrete anchors. This paper explores the feasibility of using electrical reflectometry methods for fault location on concrete anchors. Anchors must be electrically isolated from the surrounding structure, and the best results are obtained when tests can be made <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">in situ</i> over the lifespan of the anchor. Tests on 200 foot long anchors buried in wet sand confirm the possibility of using spectral time-domain reflectometry for location of full or perhaps partial anchor damage.
Affinity Biosensing Based on Surface Plasmon Resonance Detection (2003)

Interaction between molecules is the basis for life in cells and higher organisms. Detailed investigations of the intimate relationship between the structural properties of interacting molecules and then biological function, and the biological consequences of their interactions are therefore central research topics in modern molecular biology. The molecular interactions referred to here can be of many types; for example, antibody—antigen, receptor—ligand, and DNA-protein. The above issues must generally be addressed on different levels of molecular complexity, including organisms, cells, proteins, and peptides, as well as low-mol-wt species like hormones, vitamins, ammo acids, sugars, and so forth, by employing a broad range of biochemically and biologically oriented methods and assays. Development of new technology with improved sensitivity, specificity, and speed is therefore exceedingly important in order to be able to meet the increasing demands from the molecular biologists.
An improved telemedicine system for remote titration and optimization of Home Mechanical Ventilation (2010)

Home Mechanical Ventilation is applied to patients with different chronic respiratory diseases and, in order to be effective, it requires accurate individual titration. Nowadays this can be obtained only in the hospital during day or night visits, and this is associated with long waiting lists and high costs. The aim of this work was to realize and test a simple system that allows a remote titration of the ventilator at the patient's home by a physician at the hospital. The system is derived from the one we developed in a previous study. It is based on a simple and low cost embedded device with a mobile phone GPRS data network modem and a short-range wireless module, used to provide wireless connection with a pulse oxymeter. The device is connected to a mechanical ventilator and to an infrared webcam through USB ports. When the ventilator is in operation, the system acquires and stores data from it and from the pulse oxymeter. It also connects to Internet and waits for remote connections. The physician can connect and look at the patient's ventilator tracings, oxygen saturation and heart rate and, if needed, he can also ask for snapshots of the patient through the webcam. Based on this information, the physician can also change ventilator settings to titrate the ventilator parameters depending on the patient conditions. The system was tested during a titration procedure performed at the hospital with the ventilator controlled remotely by a physician. The results of this pilot trial showed that with this system it was possible to titrate accurately patient ventilation. Given its simplicity and low-cost, this system could provide an effective way to remotely titrate home mechanical ventilation and to periodically verify its appropriateness for the actual conditions of the patients.
Nonmetabolizable Glucose Compounds Impart Cryotolerance to Primary Rat Hepatocytes (2006)

We herein report a novel method for the cryopreservation of hepatocytes using a non-metabolizable glucose derivative in an attempt to mimic the natural cryoprotective adaptations observed in freeze-tolerant frogs. Primary rat hepatocytes were loaded with 3-O-methyl glucose (3OMG) through endogenous glucose transporters without evident toxicity. The 3OMG-loaded hepatocytes were then frozen in a controlled rate freezer down to -80 degrees C and stored in liquid nitrogen at -196 degrees C. Hepatocytes cryopreserved with a relatively small amount of intracellular 3OMG (<0.2 M) showed high post-thaw viability and maintained long-term hepatospecific functions, including synthesis, metabolism, and detoxification. Metabolite uptake and secretion rates were also largely preserved in the cryopreserved hepatocytes. This is the first study to demonstrate the use of the non-metabolizable glucose derivative 3OMG in hepatocyte cryopreservation.
Perfect Recovery Conditions for Non-negative Sparse Modeling (2016)

Sparse modeling has been widely and successfully used in many applications, such as computer vision, machine learning, and pattern recognition. Accompanied with those applications, significant research has studied the theoretical limits and algorithm design for convex relaxations in sparse modeling. However, theoretical analyses on non-negative versions of sparse modeling are limited in the literature either to a noiseless setting or a scenario with a specific statistical noise model, such as Gaussian noise. This paper studies the performance of non-negative sparse modeling in a more general scenario where the observed signals have an unknown arbitrary distortion, especially focusing on non-negativity constrained and L1-penalized least squares, and gives an exact bound for which this problem can recover the correct signal elements. We pose two conditions to guarantee the correct signal recovery: minimum coefficient condition and nonlinearity versus subset coherence condition. The former defines the minimum weight for each of the correct atoms present in the signal and the latter defines the tolerable deviation from the linear model relative to the positive subset coherence, a novel type of “coherence” metric. We provide rigorous performance guarantees based on these conditions and experimentally verify their precise predictive power in a hyperspectral data unmixing application.
A Role of Chondroitin Sulfate Glycosaminoglycan Binding Site in α4β1 Integrin-mediated Melanoma Cell Adhesion (1998)

We have previously reported that alpha4beta1 (but not alpha5beta1) integrin-mediated melanoma cell adhesion is inhibited by removal of cell surface chondroitin sulfate glycosaminoglycan (CSGAG), suggesting that melanoma chondroitin sulfate proteoglycan plays a role in modulating the adhesive function of alpha4beta1 integrin. In the current study, we demonstrated that alpha4beta1 integrin binds to CSGAG. We have identified a peptide from within alpha4 integrin termed SG1 (KKEKDIMKKTI) that binds to cell surface melanoma chondroitin sulfate proteoglycan, indicating that SG1 represents a CSGAG binding site within the alpha4 integrin subunit. Soluble SG1 inhibits alpha4beta1 integrin-mediated human melanoma cell adhesion to CS1. Polyclonal antibody generated against the peptide inhibits melanoma cell adhesion to CS1, and the inhibition is reversed by Mn2+ and an activating monoclonal antibody anti-beta1 (8A2). Additionally, pretreatment of cells with anti-SG1 IgG inhibits the expression of the monoclonal antibody 15/7 epitope in the presence of soluble CS1 peptide, suggesting that anti-SG1 IgG prevents ligand binding by alpha4beta1 integrin. These results demonstrate that alpha4beta1 integrin interacts directly with CSGAG through SG1 site, and that this site can affect the ligand binding properties of the integrin.

A Novel Backup Distance Protection Scheme for Series-Compensated Transmission Lines (2013)

Conventional distance protection applies the positive-sequence impedance to protect a line against short-circuit faults. Series-compensated lines may considerably change the positive-sequence impedance of the fault path and cause the distance relays to maloperate. To overcome this problem, the mutual impedance between phases of a transmission line is used for the design of a new distance protection scheme. The voltages and currents of both ends of the line are applied to compute the mutual impedance between the relay and the fault point. The proposed scheme has a reliable performance in protection against single-phase and double-phase-to-ground faults and, therefore, it can be used as a backup protection. Simulation results approve the efficiency of the proposed method in protection of series-compensated transmission lines.
Next place prediction by understanding mobility patterns (2015)

As technology to connect people across the world is advancing, there should be corresponding advancement in taking advantage of data that is generated out of such connection. To that end, next place prediction is an important problem for mobility data. In this paper we propose several models using dynamic Bayesian network (DBN). Idea behind development of these models come from typical daily mobility patterns a user have. Three features (location, day of the week (DoW), and time of the day (ToD)) and their combinations are used to develop these models. Knowing that not all models work well for all situations, we developed three combined models using least entropy, highest probability and ensemble. Extensive performance study is conducted to compare these models over two different mobility data sets: a CDR data and Nokia mobile data which is based on GPS. Results show that least entropy and highest probability DBNs perform the best.
Detecting linkage for genetically heterogeneous diseases and detecting heterogeneity with linkage data. (1986)

Interest in searching for genetic linkage between diseases and marker loci has been greatly increased by the recent introduction of DNA polymorphisms. However, even for the most well-behaved Mendelian disorders, those with clear-cut mode of inheritance, complete penetrance, and no phenocopies, genetic heterogeneity may exist; that is, in the population there may be more than one locus that can determine the disease, and these loci may not be linked. In such cases, two questions arise: (1) What sample size is necessary to detect linkage for a genetically heterogeneous disease? (2) What sample size is necessary to detect heterogeneity given linkage between a disease and a marker locus? We have answered these questions for the most important types of matings under specified conditions: linkage phase known or unknown, number of alleles involved in the cross at the marker locus, and different numbers of affected and unaffected children. In general, the presence of heterogeneity increases the recombination value at which lod scores peak, by an amount that increases with the degree of heterogeneity. There is a corresponding increase in the number of families necessary to establish linkage. For the specific case of backcrosses between disease and marker loci with two alleles, linkage can be detected at recombination fractions up to 20% with reasonable numbers of families, even if only half the families carry the disease locus linked to the marker. The task is easier if more than two informative children are available or if phase is known. For recessive diseases, highly polymorphic markers with four different alleles in the parents greatly reduce the number of families required.
The NADase-Negative Variant of the Streptococcus pyogenes Toxin NAD + Glycohydrolase Induces JNK1-Mediated Programmed Cellular Necrosis (2016)

Many bacterial pathogens produce toxins that alter how infected host cells interact with the immune system. For Streptococcus pyogenes, two toxins, a NAD(+) glycohydrolase (SPN) and streptolysin O (SLO), act in combination to cause infected cells to die. However, there are two natural forms of SPN, and these variants cause dying cells to produce different types of signaling molecules. The NADase(+) form of SPN kills cells by depleting reserves of NAD(+) and cellular energy. The other form of SPN lacks this activity (NADase(-)); thus, the mechanism by which this variant induces toxicity was unknown. Here, we show that infected cells recognize NADase(-) SPN through a specific signaling molecule called JNK, which causes these cells to undergo a form of cellular suicide known as programmed necrosis. This helps us to understand how different forms of toxins alter host cell signaling to help S. pyogenes cause different types of diseases.
Computer vision signal processing on graphics processing units (2004)

This paper shows speedups attained by using computer graphics hardware for implementation of computer vision algorithms by efficiently mapping mathematical operations of computer vision onto modem computer graphics architecture. As an example computer vision algorithm, we implement a real-time projective camera motion tracking routine on modern, GeForce FX class GPUs (graphics processing units). Algorithms are implemented using OpenGL and the nVIDIA Cg fragment shaders. Trade-offs between computer vision requirements and GPU resources are discussed. Algorithm implementation is examined closely, and hardware bottlenecks are addressed to examine the performance of GPU architecture for computer vision. It is shown that significant speedups can be achieved, while leaving the CPU free for other signal processing tasks. Applications of our work include wearable, computer mediated reality systems that use both computer vision and computer graphics, and require realtime processing with low-latency and high throughput provided by modem GPUs.

Expansins in Deepwater Rice Internodes (1997)

Cell walls of deepwater rice (Oryza sativa L.) internodes undergo long-term extension (creep) when placed under tension in acidic buffers. This is indicative of the action of the cell wall-loosening protein expansin. Wall extension had a pH optimum of around 4.0 and was abolished by boiling. Acid-induced extension of boiled cell walls could be reconstituted by addition of salt-extracted rice or cucumber cell wall proteins. Cucumber expansin antibody recognized a single protein band of 24.5-kD apparent molecular mass on immunoblots of rice cell wall proteins. Expansins were partially purified by concanavalin A affinity chromatography and sulfopropyl (SP) cation-exchange chromatography. The latter yielded two peaks with extension activity (SP20 and SP29), and immunoblot analysis showed that both of these active fractions contained expansin of 24.5-kD molecular mass. The N-terminal amino acid sequence of SP20 expansin is identical to that deduced from the rice expansin cDNA Os-EXP1. The N-terminal amino acid sequence of SP29 expansin matches that deduced from the rice expansin cDNA Os-EXP2 in six of eight amino acids. Our results show that two expansins occur in the cell walls of rice internodes and that they may mediate acid-induced wall extension.
SdrX, a Serine-Aspartate Repeat Protein Expressed by Staphylococcus capitis with Collagen VI Binding Activity (2004)

Staphylococcus capitis (S. capitis) has been implicated in a large proportion of coagulase-negative staphylococcal infections in very-low-birth-weight infants. To identify potential therapeutic targets, the S. capitis genome was probed for the presence of genes encoding microbial surface components recognizing adhesive matrix molecules (MSCRAMM). By using Southern blot analysis, an S. capitis gene, designated sdrX, that contained sequence motifs consistent with the Sdr family of MSCRAMM proteins was identified. By using monospecific antisera in Western blot and flow cytometry, SdrX was demonstrated to be expressed on the surface of S. capitis. Human collagen type VI was found to bind both the recombinant A domain of SdrX and viable S. capitis expressing SdrX. SdrX is the first collagen-binding Sdr protein described and is the first MSCRAMM protein identified in S. capitis.

Recognizing Multitasked Activities from Video using Stochastic Context-Free Grammar (2001)

In this paper, we present techniques for recognizing complex, multitasked activities from video. Visual information like image features and motion appearances, combined with domain-specific information, like object context is used initially to label events. Each action event is represented with a unique symbol, allowing for a sequence of interactions to be described as an ordered symbolic string. Then, a model of stochastic context-free grammar (SCFG), which is developed using underlying rules of an activity, is used to provide the structure for recognizing semantically meaningful behavior over extended periods. Symbolic strings are parsed using the Earley-Stolcke algorithm to determine the most likely semantic derivation for recognition. Parsing substrings allows us to recognize patterns that describe high-level, complex events taking place over segments of the video sequence.
A Framework for QoS-based Routing in the Internet (1998)

QoS-based routing has been recognized as a missing piece in the evolution of QoS-based service offerings in the Internet. This document describes some of the QoS-based routing issues and requirements, and proposes a framework for QoS-based routing in the Internet. This framework is based on extending the current Internet routing model of intra and interdomain routing to support QoS.
