H1N1 hemagglutinin-specific HLA-DQ6-restricted CD4+ T cells can be readily detected in narcolepsy type 1 patients and healthy controls (2019)

Following the 2009 H1N1 influenza pandemic, an increased risk of narcolepsy type 1 was observed. Homology between an H1N1 hemagglutinin and two hypocretin sequences has been reported. T cell reactivity to these peptides was assessed in 81 narcolepsy type 1 patients and 19 HLA-DQ6-matched healthy controls. HLA-DQ6-restricted H1N1 hemagglutinin-specific T cell responses were detected in 28.4% of patients and 15.8% of controls. Despite structural homology between HLA-DQ6-hypocretin and -H1N1 peptide complexes, T cell cross-reactivity was not detected. These results indicate that it is unlikely that cross-reactivity between H1N1 hemagglutinin and hypocretin peptides presented by HLA-DQ6 is involved in the development of narcolepsy.
Improved image registration based on SIFT features (2011)

SIFT (Scale-invariant feature detection) feature has been applied on image registration. However, how to achieve an ideal matching result and reduce the matching time are the most important steps that we study in our work. The original SIFT algorithm is famous for its abundant feature points, but the final keypoints are so excessive that the matching speed is very slow at the next step of searching for homonymy point-pairs. In this paper, we analyze the performance of SIFT and conquer its deficiencies applying RANSAC arithmetic and Least Squares Method in order to reach a perfect robustness and precision. Experiments with real-world scenes demonstrate that the method can reach a better precision and robustness, which outperforms previously proposed schemes. Compared with conventional localization algorithm, this method makes the precision more stable, which reaches 0.01 pixel, and also reduce the time of image registration.

Are sutured faucial pillars really an advantage in tonsillectomy? (1996)

A prospective study was undertaken in 40 patients to determine whether suturing of the faucial pillars has any effect in relieving pain and discomfort associated with tonsillectomy. The first 20 patients (5 adults and 15 children) had tonsillectomy without suturing of the faucial pillars. The next 20 patients (3 adults and 17 children) had the anterior and posterior faucial pillars approximated and sutured with 3.0 chromic catgut. Objective methods of evaluating pain and discomfort were undertaken immediately and 24 hours postoperatively. The pain and discomfort were the same in both groups. Adults experienced more pain than children, in both groups. Complications occurred in 3 patients, all belonging to the sutured group: 2 had palatal haematoma and 1 nasal regurgitation. Approximation of the faucial pillars to cover the raw tonsillar bed after tonsillectomy does not relieve pain. It is disadvantageous in that it produces complications and prolongs the anaesthetic time significantly. Therefore suturing of the faucial pillars is not recommended.
Understanding Graph Sampling Algorithms for Social Network Analysis (2011)

Being able to keep the graph scale small while capturing the properties of the original social graph, graph sampling provides an efficient, yet inexpensive solution for social network analysis. The challenge is how to create a small, but representative sample out of the massive social graph with millions or even billions of nodes. Several sampling algorithms have been proposed in previous studies, but there lacks fair evaluation and comparison among them. In this paper, we analyze the state-of art graph sampling algorithms and evaluate their performance on some widely recognized graph properties on directed graphs using large-scale social network datasets. We evaluate not only the commonly used node degree distribution, but also clustering coefficient, which quantifies how well connected are the neighbors of a node in a graph. Through the comparison we have found that none of the algorithms is able to obtain satisfied sampling results in both of these properties, and the performance of each algorithm differs much in different kinds of datasets.
Laser‐processed high‐efficiency silicon RISE‐EWT solar cells and characterisation (2009)

Abstract The RISE‐EWT ( R ear I ntendigitated S ingle E vaporation E mitter W rap T hrough) solar cell is a silicon wafer‐based solar cell concept that is capable of achieving solar energy conversion efficiencies of over 21%. The fabrication sequence is based exclusively on industrially feasible processing steps and avoids any photolithography and masking steps, nor does it require boron diffusion. For low process complexity, the RISE‐EWT solar cell can be made with only a single phosphorus diffusion and a single evaporation step for metallisation. All structuring of the cell is based on non‐contacting laser processing. Laser technology is the key tool for processing RISE‐EWT solar cells: The cell has laser drilled and phosphorus‐diffused holes to connect the emitter layer on the front side with the emitter and the contacts on the rear side. The emitter and base contact regions are defined by laser ablation of a diffusion barrier and KOH etch prior to phosphorus diffusion. An important feature of RISE‐EWT solar cells are steep surface features (flanks) that are produced by the laser ablation and KOH‐etching. We use these flanks to achieve reliable separation between the contacts to the n ‐type polarity and to the p ‐type polarity of the solar cell. We provide a description of RISE‐EWT manufacturing process and present an analysis of the recombination losses in our cells. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Chromophores for the Delivery of Bioactive Molecules with Two-Photon Excitation (2011)

The localized release of bioactive molecules from “caged compounds” through two-photon excitation (2PE) is an emerging technology for the study of biological processes in cell and tissue culture and whole animals. Several advantages are realized when 2PE drives the activation of the biological effector: (1) excitation is tightly localized to femtoliter-sized volumes; (2) there is less photodamage to biological tissues; and (3) deeper penetration into the sample is achieved. A barrier to widespread use and an expansion of applications for the pinpoint three-dimensional delivery of biological effectors are the small number of available caging groups and phototriggers with sufficient sensitivity to 2PE, appropriate photolysis kinetics, and necessary physiological compatibility. Chromophores based on nitrobenzyl, nitroindoline, coumarin, ortho-hydroxycinnamic acid, quinoline, and other structural motifs have been designed to regulate the action of biologically active compounds with 2PE. Design principles from structure–property relationships elucidated for two-photon absorbing materials can be applied to the design of caging groups and phototriggers for high efficiency 2PE-mediated release of bioeffectors. The conjugation size, symmetry, and the strength of donor and acceptor groups impact the overall sensitivity to 2PE, but these factors must be balanced with the need for biocompatibility and the ability to drive photochemical reactions with rapid kinetics.
[An urease enzyme linked immunosorbent assay for detection of Helicobacter pylori infection]. (1993)

A sensitive and specific serological diagnostic test for Helicobacter pylori infection has been developed and validated in 120 patients with dyspeptic symptoms undergoing endoscopy. This test is to use urease, a protein unique to H. pylori, as the basis for the enzyme linked immunosorbent assay (ELISA) that detects serum H. pylori urease antibodies. The ELISA mean optical density (OD) in H. pylori-positive group is higher than that in H. pylori-negative group (0.57 +/- 0.23 vs 0.24 +/- 0.15, P < 0.001), a cut-off 0.3 OD yields a sensitivity of 95% and a specificity of 93%. Serum absorption test showed that Escherichia coli, Klebsiella pneumonia, Proteus mirabilis, Yersinia enterocolotica, Pseudomonas aeruginosa cell lysate do not influence serum H. pylori urease antibody level, though they all have urease except E. coli. The result implied that H. pylori urease can be a good antigen to detect serum H. pylori antibody and it would be useful for epidemiological survey and routine diagnostic approach. Nearly half of the blood donors showed positive result with H. pylori urease antibody. It is suggested that H. pylori infection is quite common in the asymptomatic population.
Dynamic State Estimation (2005)

A Dynamic state estimator is proposed to give better representation for the time evolution of the state of the system. The Dynamic state estimation utilizes, in addition to the static one, the previous estimate of the state, along with the information on its reliability and the changes that the state is likely to have undergone. This approach consists of predicting the state vector based on past estimation, followed by a filtering process performed when a new set of measurements is available. Dynamic estimator for a Power system is proposed based on exponential smoothing and least squares estimation techniques. For computational purposes a decoupling principle is applied, where active and reactive variables are decoupled. This decoupling principle reduces storage requirements and computational time.
Identification of a Salmonellosis Outbreak by Means of Molecular Sequencing (2011)

The complexity of the modern food supply makes identifying foodborne outbreaks difficult. In this report, FDA investigators identify a 44-state outbreak of Salmonella enterica serotype Montevideo, using molecular sequencing.
Deep & Cross Network for Ad Click Predictions (2017)

Feature engineering has been the key to the success of many prediction models. However, the process is non-trivial and often requires manual feature engineering or exhaustive searching. DNNs are able to automatically learn feature interactions; however, they generate all the interactions implicitly, and are not necessarily efficient in learning all types of cross features. In this paper, we propose the Deep & Cross Network (DCN) which keeps the benefits of a DNN model, and beyond that, it introduces a novel cross network that is more efficient in learning certain bounded-degree feature interactions. In particular, DCN explicitly applies feature crossing at each layer, requires no manual feature engineering, and adds negligible extra complexity to the DNN model. Our experimental results have demonstrated its superiority over the state-of-art algorithms on the CTR prediction dataset and dense classification dataset, in terms of both model accuracy and memory usage.
Enalapril Attenuates Downregulation of Angiotensin-Converting Enzyme 2 in the Late Phase of Ventricular Dysfunction in Myocardial Infarcted Rat (2006)

The early and long-term effects of coronary artery ligation on the plasma and left ventricular angiotensin-converting enzyme (ACE and ACE2) activities, ACE and ACE2 mRNA levels, circulating angiotensin (Ang) levels [Ang I, Ang-(1-7), Ang-(1-9), and Ang II], and cardiac function were evaluated 1 and 8 weeks after experimental myocardial infarction in adult Sprague Dawley rats. Sham-operated rats were used as controls. Coronary artery ligation caused myocardial infarction, hypertrophy, and dysfunction 8 weeks after surgery. At week 1, circulating Ang II and Ang-(1-9) levels as well as left ventricular and plasma ACE and ACE2 activities increased in myocardial-infarcted rats as compared with controls. At 8 weeks post-myocardial infarction, circulating ACE activity, ACE mRNA levels, and Ang II levels remained higher, but plasma and left ventricular ACE2 activities and mRNA levels and circulating levels of Ang-(1-9) were lower than in controls. No changes in plasma Ang-(1-7) levels were observed at any time. Enalapril prevented cardiac hypertrophy and dysfunction as well as the changes in left ventricular ACE, left ventricular and plasmatic ACE2, and circulating levels of Ang II and Ang-(1-9) after 8 weeks postinfarction. Thus, the decrease in ACE2 expression and activity and circulating Ang-(1-9) levels in late ventricular dysfunction post-myocardial infarction were prevented with enalapril. These findings suggest that in this second arm of the renin-angiotensin system, ACE2 may act through Ang-(1-9), rather than Ang-(1-7), as a counterregulator of the first arm, where ACE catalyzes the formation of Ang II.
Prevencion y Seguridad en Entornos Aeroportuarios (2019)

espanolLos aeropuertos son infraestructuras criticas necesitadas de especiales medidas de seguridad. El avance de la tecnologia abre la puerta al uso de novedosos sistemas de seguridad a la par que se producen evoluciones en la tipologia de las fuentes de riesgo o amenazas que encuentran respuesta en la implantacion estas medidas, otras ya operativas y las que de manera progresiva se estan implantando progresivamente como el caso de los escaneres corporales. La utilizacion de sistemas biometricos para la identificacion personal y la entrada en escena de los drones y sus contramedidas son algunas de las novedades en cuanto a sistemas de seguridad se refiere. Los perros detectores son otro segmento de medidas utilizadas en ambitos aeroportuarios. La formacion continua y especializada para el personal de seguridad e incluso la aparicion de conceptos relacionados con la seguridad colaborativa apoyadas en las TIC podran complementar a las medidas tradicionales. EnglishAirports are critical infraestructures which need a special security measures. Technology makes posible to manage new security systems, but at the same time new menaces and risks surround it, making it able to study them to find out the best answers and results to be implemented not only this new measures but also operatives too, as for example, corporal scanners. Use of biometric systems for personal identification, lastest drone operations and its response, are some of the news in security systems. Canine detection units are another kind method used in airport security. A high level of specialized and continue formation for securty personel and new concepts of colaborative security working with software aplications will help traditional security measures to keep on improving.
Using the analytical hierachy process to construct performance indicators for comprehensive high schools in Taiwan (2011)

In recent years numerous position papers (Visscher, 2001; Wang, Shieh, & Wang, 2008) have been written about the need for ensuring the efficient and effective performance of educational institutions and an increasing number of policy makers are advocating that educational institutions be held accountable for their performance. Our purpose in this study was to construct performance indicators (PIs) for comprehensive high schools (CHSs), which provide general and occupational education programs. A literature review was completed, a panel discussion held, and field interviews were conducted. An analytical hierarchy process was used to make decisions on a framework of PIs for CHSs in Taiwan. The 2 main conclusions were that the most important indicator of performance in CHSs is the domain of "student and development" and that the difference between the experts' and practitioners' viewpoints on those schools' performances should be addressed in the near future.
A temporal bipartitioning algorithm for dynamically reconfigurable FPGAs (2001)

This paper will describe a systematic method to map synchronous digital systems into dynamically reconfigurable programmable logic (i.e., programmable logic able to swap in real time the configuration defining the functionality of the system). The method is based on a temporal bipartitioning technique that is able to separate the static implementation of a circuit in two temporal independence hardware contexts. As the experimental results show, the method is capable of improving the functional density of the dynamic implementation with respect to the static one.
Subcellular Fractionation of Tissue Culture Cells (2003)

Cell fractionation techniques include some of the most important and widely used analytical tools in cell and molecular biology, and are essential for the development of cell-free assays that reconstitute complicated cellular processes. In addition to simple gradient systems, this unit discusses the immuno-purification of organelles, in particular endosomes. As antigens, purification can be achieved using endogenous or ectopically expressed proteins, provided that appropriate antibodies are available. Alternatively, tagged proteins can be used, when combined with anti-tag antibodies. Now that sequencing of the genomes of several organisms has been completed, biochemical strategies, and in particular fractionation and in vitro transport assays, are more necessary than ever to study the numerous protein and protein complexes that are being discovered.
Neurocognitive profile in major depressive disorders: relationship to symptom level and subjective memory complaints (2016)

The MCCB was applicable in this study of major depressive disorder, and revealed significant neurocognitive dysfunction in this group. At least one fifth of the patients were impaired on all cognitive domains, with Speed of Processing and Reasoning/Problem Solving being most strongly affected. The objective test scores were significantly related to depression severity, but not to subjective cognitive complaints.
Reliable face anti-spoofing using multispectral SWIR imaging (2016)

Recent studies point out that spoofing attacks using facial masks still are a severe problem for current biometric face recognition (FR) systems. As such systems are becoming more frequently used, for example, for automated border crossing or access control to critical infrastructure, advanced anti-spoofing techniques are necessary to counter these attacks. This work presents a novel, cross-modal approach that enhances existing solutions for face verification and uses multispectral short wave infrared (SWIR) imaging to ensure the authenticity of a face even in the presence of partial disguises and masks. It is evaluated on a dataset containing 137 subjects and a variety of spoofing attacks. Using a commercial FR system, it successfully rejects all attempts to counterfeit a foreign face with a false acceptance rate FAR <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">cf</sub> = 0% and most attempts to disguise the own identity with FAR <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dg</sub> = 1% at a false rejection rate of FRR <; 5% using SWIR images for verification.

Cytokine-induced production of monocyte chemoattractant protein-1 by cultured human mesangial cells (1992)

The infiltration of the glomerulus by monocyte-derived macrophages is an important step in the pathogenesis of glomerular injury. The factors regulating glomerular leukocyte traffic remain unknown. We postulated that the glomerular mesangial cell (MC) may participate in the development of glomerular inflammation through the production of the monocyte-specific chemotactic factor, monocyte chemoattractant protein-1 (MCP-1). Using a cell culture system, we found that human MC produced a basal level of monocyte chemotactic activity, which was significantly increased by the inflammatory cytokines IL-1 beta and TNF-alpha. This increase in bioactivity correlated with the increased expression of MCP-1 mRNA by cytokine-conditioned MC. The total chemotactic activity of MC-conditioned supernatants was reduced by more than 80% after immunoadsorption with a specific anti-MCP-1 antibody. Thus, MC could play a role in inflammatory glomerular conditions through the production of MCP-1.
A phantom study of the quantitative behavior of Bayesian PET reconstruction methods (2002)

The authors examine the behavior of a Bayesian protocol for reconstruction of PET images in terms of the quantitative accuracy of the resulting Region-of-Interest (ROI) statistics. The authors' protocol uses a rapidly converging algorithm to compute a MAP estimate of the 3D PET image and includes novel methods for accurate attenuation and scatter modeling. The image is modeled using a Gibbs prior whose hyperparameters are estimated simultaneously with the PET image so that no critical user specified parameters are required. The authors computed ROI statistics over reconstructions of multiple frames of a computer generated brain phantom and an experimental chest phantom scanned using a Siemens/CTI ECAT931 scanner. Results indicate significant improvements in both bias and variance when compared to a standard filtered backprojection (FBP) based protocol.
Distributed join processing performance evaluation (1994)

Efficient join acceleration methods that combine hybrid hashing, join indices and domain vectors with semi-join techniques to accelerate distributed joins are developed. An analytic performance model which allows for parallel execution of the methods at each join site is developed to compare the total task duration time of the methods. The methods are compared over a wide range of memory sizes, semijoin selectivities and network transmission speeds. The distributed join index method performs well if memory size is large and selectivity is low. The distributed hybrid hash method always has the advantage that it requires no residual data to be stored between runs, however performance is poor at low network transmission rates due to high pre-semijoin transmission requirements. The distributed domain vector hash method performs well in high selectivity conditions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
