Breaking News Detection and Tracking in Twitter (2010)

Twitter has been used as one of the communication channels for spreading breaking news. We propose a method to collect, group, rank and track breaking news in Twitter. Since short length messages make similarity comparison difficult, we boost scores on proper nouns to improve the grouping results. Each group is ranked based on popularity and reliability factors. Current detection method is limited to facts part of messages. We developed an application called “Hotstream” based on the proposed method. Users can discover breaking news from the Twitter timeline. Each story is provided with the information of message originator, story development and activity chart. This provides a convenient way for people to follow breaking news and stay informed with real-time updates.
B-Type Natriuretic Peptides Help in Cardioembolic Stroke Diagnosis (2015)

Natriuretic peptides are strongly increased in cardioembolic strokes. Future multicentre prospective studies comparing BNP and NT-proBNP might aid in finding the optimal biomarker, the best time point, and the optimal cutoff points for cardioembolic stroke identification.

Threshold Voltage Fluctuation by Random Telegraph Noise in Floating Gate nand Flash Memory String (2010)

Read current fluctuation (ΔI <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">read</sub> ) due to random telegraph noise was measured from a cell in a NAND flash memory cell string, and its effect on threshold voltage fluctuation (ΔV <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sub> ) was analyzed. Sixteen-level fluctuation (four traps) was observed in a 60-nm cell of a cell string (ΔI <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">read</sub> /I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">read</sub> of ~0.4).

A novel near-field robotic scanner for surface, RF and thermal characterization of millimeter-wave active phased array antenna (2016)

This work describes the concept and current development of a novel automated system to characterize active phased array antennas. The proposed system, called an RF Scanner, has been conceptualized and developed by the Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU). This system enables the full characterization of electromagnetic, surface, and thermal properties of an active phased array antenna. An industrial 6-axis articulated robot is used to move a sensor suite to perform near-field measurements as well as surface and thermal inspection of the antenna under test (AUT). The sensor suite consists of a mechanical fixture supporting an infrared camera, a high-precision laser, a high-definition camera, and an antenna array probe. The AUT, the robotic manipulator, and the sensor suite are located inside of an environmental chamber. This environmental chamber enables characterization of the AUT under controlled temperature and humidity. The combination of the high precision robot, sensor suite, environmental chamber, and vector network analyzer (VNA), along with a software interface, allows fully automated characterization of an active phased array antenna from 1 GHz to 18 GHz, up to 60 GHz if the VNA is upgraded, over a temperature range of 0° C to 50 ° C.
Improved parallel algorithm for transient stability simulation and analysis of its speedup (2006)

An improved parallel - in - space algorithm based on factorization path tree partitioning is proposed for transient stability simulation. To make the distribution of computing load among processors more reasonable,a new performance index for assessing the partitioning scheme and a post - adjusting strategy are adopted for the task assignment in this algorithm. A formula,which can be used to estimate the speedup under the ideal circumstance for this new algorithm is given,and the factors which influence the efficiency of the parallel simulation is analyzed. A method to evaluate the quantity of processors needed to achieve the maximum speedup is presented and is applied to a 3 872 - bus power system for test. The simulation results obtained on the Cluster 1 350 for the test power system validates that the improved algorithm has higher efficiency than the conventional one. This project is supported by National Natural Science Fund of China(50595412).
New Morphological Features for Grading Pancreatic Ductal Adenocarcinomas (2013)

Pathological diagnosis is influenced by subjective factors such as the individual experience and knowledge of doctors. Therefore, it may be interpreted in different ways for the same symptoms. The appearance of digital pathology has created good foundation for objective diagnoses based on quantitative feature analysis. Recently, numerous studies are being done to develop automated diagnosis based on the digital pathology. But there are as of yet no general automated methods for pathological diagnosis due to its specific nature. Therefore, specific methods according to a type of disease and a lesion could be designed. This study proposes quantitative features that are designed to diagnose pancreatic ductal adenocarcinomas. In the diagnosis of pancreatic ductal adenocarcinomas, the region of interest is a duct that consists of lumen and epithelium. Therefore, we first segment the lumen and epithelial nuclei from a tissue image. Then, we extract the specific features to diagnose the pancreatic ductal adenocarcinoma from the segmented objects. The experiment evaluated the classification performance of the SVM learned by the proposed features. The results showed an accuracy of 94.38% in the experiment distinguishing between pancreatic ductal adenocarcinomas and normal tissue and a classification accuracy of 77.03% distinguishing between the stages of pancreatic ductal adenocarcinomas.
Nurses' attitudes and beliefs about medication errors in a UK hospital (2000)

Abstract Objective To investigate nurses' attitudes and beliefs about medication administration and medication system errors, and to determine the impact of these attitudes and beliefs at ward level. Method Semi-structured interviews with a purposive sample of nurses who had been selected initially by ward specialty and then by grade. Setting A teaching hospital in London, United Kingdom. Key findings Seventeen nurses were interviewed and their attitudes and beliefs about types of medication errors, causes of medication errors, reporting of medication errors and the responsibility for medication errors were explored. The types of errors mentioned by the nurses were consistent with those cited in the literature. Nurses believed both doctors and pharmacy staff to be sources of errors but by far the most common source of error was said to be the nurses themselves. Few of the nurses interviewed believed all errors were reported and almost all believed they were responsible for any errors which occurred when they were administering drugs. As well as blaming themselves, some also blamed the pharmacist and the doctor, if they had been involved. The nurses thought the fear of disciplinary action and having to admit to making a “silly” mistake stopped a nurse from reporting an error if it had no ill effects on the patient. They hoped anything that could harm the patient would be reported, as would any errors involving intravenous drugs, Controlled Drugs and drugs with serious side effects. They believed errors should be reported to the nurse in charge of the ward, the doctor and sometimes the ward manager, if necessary. Generally the nurses felt the patient should be informed if they might suffer any ill effects due to the error; if the error was not going to harm the patient, the nurses were divided as to whether the patient should even be told an error had occurred. Conclusion It was felt that medication errors should be a learning experience which could allow the nurse to reflect on her own practice. The emphasis of errors should be shifted from the nurse to the situation in which it occurred as blaming the nurse was not considered to be very constructive.
Relationship between circulating tumor cells and peripheral T-cells in patients with primary breast cancer. (2013)

Absence of T-cell help at the time of priming may result in a loss of long-term antigen-activation of CD8 lymphocytes and could lead to an ineffective anti-tumor cell response. This might contribute to systemic immunosuppression and open the door for tumor cell dormancy.
Zwitteration As an Alternative to PEGylation (2011)

A direct, head-to-head comparison of the efficacy of a zwitterionic versus a poly(ethylene glycol), PEG, coating in preventing protein adsorption to silica and aggregation of silica nanoparticles is presented. The same siloxane coupling chemistry was employed to yield surfaces with similar coverages of both types of ligand. Nanoparticle and planar surfaces were challenged with salt, serum, lysozyme, and serum albumin at 25 and 37 °C. While both types of surface modification are highly effective in preventing protein adsorption and nanoparticle aggregation, the zwitterion provided monolayer-type coverage with minimal thickness, whereas the PEG appeared to yield a more three-dimensional coating. The mechanism for adsorption resistance is thought to be based on preventing ion pairing between protein and surface charges, which releases counterions and water molecules, an entropic driving force enough to overcome a disfavored enthalpy of adsorption.
Accuracy analysis for TDOA localization in sensor networks (2011)

In this paper, passive emitter localization using Time Difference of Arrival (TDOA) measurements within a sensor network is investigated. Contrary to the case of a moving sensor pair the fact of correlated measurements in a single time step arises dependent on the choice of the measurement set. In tracking simulations, the Cramér Rao Lower Bound (CRLB) and simulation results are often computed assuming constant standard deviations of the incoming measurements. Though, the measurement error is parameter dependent, it depends for example on the emitter-sensors-geometry. In Monte Carlo simulations, a comparison is performed between the localization in a static sensor network with three sensors and the localization using a moving sensor pair. Measurements are generated assuming additive white Gaussian noise with constant and parameter dependent variance. Results confirm the attainable localization accuracy and show the superior performance of an additional sensor compared t o additional motion.
Luces y sombras del procedimiento para el cierre de páginas web: a propósito del desarrollo reglamentario de la «Ley Sinde» (2012)

Internet es hoy en dia el «agora publica» de la sociedad del siglo XXI y se presenta como un espacio proclive al ejercicio de las libertades publicas y muy especialmente del intercambio de todo tipo de contenidos, si bien algunos de los cuales son obras protegidas por la normativa de propiedad intelectual que no cuentan con la correspondiente autorizacion de sus titulares o representantes. El presente estudio analiza y cuestiona la respuesta penal y administrativa que, segun la legislacion espanola, merece este fenomeno. Particularmente es objeto de examen el procedimiento para el cierre de paginas web que tiene su causa en la Disposicion final num. 43.4 de la Ley 2/2011, de 4 de marzo, de Economia Sostenible (popularmente denominada «Ley Sinde») y desarrolla el RD 1889/2011, de 30 de diciembre, por el que se regula el funcionamiento de la Comision de Propiedad Intelectual.
Approaches to maintaining provenance throughout the additive manufacturing process (2013)

The development of 3D printers has resulted in significant Intellectual Property Right issues. This work presents a model for signing printable 3D objects. The paper initially reviews the security principles of signing of objects in both digital or physical form, and the metrics for assessing signatures. 3D designs are not just a file, but actual physical objects and should be treated identically, to digital documents that have associated intellectual property rights and copyright protection. In this paper we propose a signing methodology intended to resolve issues with the adaptation of rapid prototyping and 3D printing by users both in engineering and the humanities. The proposed digital signing methodology is based on physical signing principles that follow archival principles to maintain accurate records. The new model allows the transition of provenance between digital and physical form.
Intergeneric Coaggregation among Drinking Water Bacteria: Evidence of a Role for <i>Acinetobacter calcoaceticus</i> as a Bridging Bacterium (2007)

Intergeneric coaggregation of drinking water bacteria was tested. Acinetobacter calcoaceticus was found not only to autoaggregate but also to coaggregate with four of the five other isolates (Burkholderia cepacia, Methylobacterium sp., Mycobacterium mucogenicum, Sphingomonas capsulata, and Staphylococcus sp.). In its absence, no coaggregation was found. Interactions were lectin-saccharide mediated. The putative bridging function of A. calcoaceticus was evidenced by multispecies biofilm studies, through a strain exclusion process.
<title>Chemo- and biosensor microsystems for clinical applications</title> (1998)

A miniaturized microanalytical device for the simultaneous monitoring of different metabolites was realized by assembling of a biosensor array produced by thin film technology with a flow-through cell produced by printed circuit board technology. The biosensor array comprises four working electrodes which can be individually configured. Glucose and lactate devices were made for whole blood monitoring. Ex vivo experiments, performed on animals, where the device was continuously operated in an extracorporeal undiluted heparinized blood stream without loss in sensitivity for 48 hours, gave close tracing to routinely used clinical analyzers by using one point in vitro calibration.

The temperature dependence of the magnetic-exchange behavior between the EuS and the Co phase in the macroscopic ferrimagnet ${\mathrm{Co}}_{1\ensuremath{-}x}(\mathrm{EuS}{)}_{x}$ has been studied over a wide composition range, $0.1<~x<~0.6,$ using magnetooptic spectroscopy. We find a strong exchange-induced enhancement of the Curie temperature of the EuS phase for EuS concentrations $x>~0.2$ reaching a maximum of 160 K in ${\mathrm{Co}}_{0.6}{(\mathrm{EuS})}_{0.4}.$ This is an order of magnitude higher than in bulk EuS. The maximum enhancement takes place at the concentration where a percolation from metallic to a semiconducting behavior occurs. The results are explained by the nanometer size of the EuS crystallites, which leads to a large surface-to-volume ratio. This yields a strong exchange interaction to the Co matrix while the crystallinity of the EuS ensures a high-spin ${\mathrm{Eu}}^{2+}$ state.
Effects of Combination of Calcium and Aspirin on Azoxymethane-Induced Aberrant Crypt Foci Formation in the Colons of Mice and Rats (2008)

Human intervention studies have suggested an exciting synergistic action between calcium supplementation and aspirin intake in reducing the risk of colorectal cancer. The aim of this study was to determine whether such a synergy can be demonstrated on azoxymethane (AOM)-induced colon aberrant crypt foci (ACF) formation in mice and rats. Female CF-1 mice and male F344 rats were injected subcutaneously with AOM and then received diet treatments for 8 wk. The basal control diet contained high fat (20% mixed lipids by weight) and low calcium (1.4 mg/g diet) to mimic the average Western diet. The treatment diets contained enriched calcium (5.2 mg calcium/g diet), aspirin (0.2 mg aspirin/g diet), or calcium plus aspirin (5.2 mg calcium plus 0.2 mg aspirin/g diet). Treatment with calcium, aspirin, or their combination significantly decreased the number of total ACF and aberrant crypt per mouse (by 43-59%) or rat (by 23-38%), but statistically significant differences among the 3 groups were not observed. A hint of additivity between calcium and aspirin was observed in mice but not in rats. These results indicate that the combination of calcium and aspirin did not produce a synergistic effect on the ACF formation in AOM-treated mice and rats.
Collaborative Behavior for Vehicle Replacement in AUV Formations (2005)

The Navy would like to use platoons of cooperating Autonomous Underwater Vehicles (AUVs) for large area underwater mine countermeasures (MCM). Collaborative behavior requires a common language, control structure, and logic so the AUVs can coordinate their action through communication. The loss of an AUV (can no longer perform assigned tasks) is a problem the formation is likely to face. The formation must compensate for lost AUVs, or time would be wasted in researching the area. In order to replace a lost AUV, the formation must determine when a vehicle is lost and what to do if a vehicle returns after being declared lost. To address these problems, fuzzy logic was used to determine when an AUV should be replaced, and a logic structure was developed to insert returning AUVs. Computer simulations showed that the logics increased the defined performance index by about 70% over the baseline case.
Spatiotemporal Regulation of a Legionella pneumophila T4SS Substrate by the Metaeffector SidJ (2015)

Modulation of host cell function is vital for intracellular pathogens to survive and replicate within host cells. Most commonly, these pathogens utilize specialized secretion systems to inject substrates (also called effector proteins) that function as toxins within host cells. Since it would be detrimental for an intracellular pathogen to immediately kill its host cell, it is essential that secreted toxins be inactivated or degraded after they have served their purpose. The pathogen Legionella pneumophila represents an ideal system to study interactions between toxins as it survives within host cells for approximately a day and its Dot/Icm type IVB secretion system (T4SS) injects a vast number of toxins. Previously we reported that the Dot/Icm substrates SidE, SdeA, SdeB, and SdeC (known as the SidE family of effectors) are secreted into host cells, where they localize to the cytoplasmic face of the Legionella containing vacuole (LCV) in the early stages of infection. SidJ, another effector that is unrelated to the SidE family, is also encoded in the sdeC-sdeA locus. Interestingly, while over-expression of SidE family proteins in a wild type Legionella strain has no effect, we found that their over-expression in a ∆sidJ mutant completely inhibits intracellular growth of the strain. In addition, we found expression of SidE proteins is toxic in both yeast and mammalian HEK293 cells, but this toxicity can be suppressed by co-expression of SidJ, suggesting that SidJ may modulate the function of SidE family proteins. Finally, we were able to demonstrate both in vivo and in vitro that SidJ acts on SidE proteins to mediate their disappearance from the LCV, thereby preventing lethal intoxication of host cells. Based on these findings, we propose that SidJ acts as a metaeffector to control the activity of other Legionella effectors.
Combining mapping and citation analysis for evaluative bibliometric purposes: A bibliometric study (1999)

The general aim of the article is to demonstrate how the results both of a structural analysis, and of a research performance assessment of a research field, can be enriched by combining elements of both into one integrated analysis. In addition, a procedure is discussed to select and analyse candidate benchmark institutes to assess the position of a particular research institute, in terms of both its cognitive orientation and its scientific production and impact at the international research front. The combined method is applied in an evaluation of the research scope and performance of the Inter-university Centre for Micro-Electronics (IMEC) in Leuven, Belgium. On the basis of the comments of an international panel of experts in micro-electronics, the method was discussed in detail. We concluded that the method provides a detailed and useful picture of the position of the institute from an international perspective. Moreover, we found that the results of each of the two parts are an added value to the other.
