Multi-camera matching under illumination change over time (2008)

Abstract. Illumination differences between disjoint cameras can have a dramatic effect on the appearance of objects, thus increasing the difficulty of multi-camera object association. Although methods to model these inter-camera illumination conditions exist, they often rely on static illumination conditions and are unable to copewith unpredictable illumination changes over time. In this paper we propose a novel method for multi-camera object association based on adapting a learned intercamera illumination mapping function to new illumination conditions over time without the need for a manual training stage using new foreground objects. Comparative experiments are carried out using challenging data taken from a disjoint camera network. The results demonstrate that the proposed method outperforms a number of existing methods given changing illumination conditions. 1
A Frequency Domain Approach for Tuning Control Parameters of CNC Servomotors to Enhance its Circular Contouring Accuracy (2017)

The machining of a cone frustum as specified in National Aerospace Standard NAS-979 is a widely accepted test to evaluate the performance of five-axis machining centers. By measuring the cross-sectional circularity or roundness of the cone, the contouring accuracy of five-axis computer numerical control (CNC) can be evaluated. Thus, reduction of circularity is directly related to improvement of the contouring accuracy in circular motions. Most CNC actuators are AC servo motors that are precisely controlled via two closed loops—one each for position and velocity. The circular contouring accuracy of a five-axis CNC can be improved by adjusting the loop gains and the time constant of velocity loop integration. Although higher gains enable the servomotors to reach the desired positions faster, the resulting contouring accuracy may not be satisfactory. Furthermore, excessively high gains may cause vibrations. This paper proposes a frequency domain approach for tuning the control parameters for each axis so that their frequency responses are very similar, thus reducing the circularity value of the cross sections of a manufactured cone frustum. The paper also describes a method to obtain the frequency response of each axis by using properly engineered input chirp sine signals. Simulated results showing the effect of tuning the control loop parameters based on the frequency response of each axis are presented. Moreover, a case study was conducted to show the variation in the circularity value when the control parameters of each axis were tuned to obtain similar frequency responses of the linear and rotary axes within a frequency range.
Serologic studies of bovine respiratory syncytial virus in Minnesota cattle (1985)

Serum antibody titers to bovine respiratory syncytial virus were determined for 559 cattle. Serum samples were obtained through the Minnesota State-Federal Brucellosis Laboratory and were collected over a 1-year period. Results of this study revealed an antibody prevalence of 65.5% to bovine respiratory syncytial virus. The distribution of antibody titers is presented, as well as analysis of titers based on breed, sex, and age of the cattle.
An efficient minimum spanning tree based clustering algorithm (2009)

Clustering analysis has been an emerging research issue in data mining due its variety of applications. In the recent years, it has become an essential tool for gene expression analysis. Many clustering algorithms have been proposed so far. However, each algorithm has its own merits and demerits and can not work for all real situations. In this paper, we present a clustering algorithm that is inspired by minimum spanning tree. To automate and evaluate our algorithm, we incorporate the concept of ratio between the intra-cluster distance (measuring compactness) and the inter-cluster distance (measuring isolation). Experimental results on some complex as well as real world data sets reveal that the proposed algorithm is efficient and competitive with the existing clustering algorithms.

Predictable Peptide Conjugation Ratios by Activation of Proteins with Succinimidyl Iodoacetate (SIA) (2017)

The small heterobifunctional linker succinimidyl iodoacetate (SIA) was examined for the preparation of peptide-protein bioconjugates with predicable conjugation ratios. For many conjugation protocols, the protein is either treated with a reductant to cleave disulfide bonds or is reacted with thiolation chemicals, such as Traut's reagent. Both approaches are difficult to control, need individual optimization and often lead to unsatisfactory results. In another popular approach, a heterobifunctional linker with a <i>N</i>-hydroxysuccinimide (NHS) and a maleimide functionality is applied to the protein. After the activation of some lysine ε-amino groups with the NHS ester functionality, a cysteine-containing peptide is attached to the activated carrier protein via maleimide. Particularly, the maleimide reaction leads to some unwanted byproducts or even cleavage of the linker. Many protocols end up with conjugates with unpredictable and irreproducible conjugation ratios. In addition, the maleimide-thiol addition product should be assumed immunogenic <i>in vivo</i>. To avoid these and other disadvantages of the maleimide approach, we examined the known linker succinimidyl iodoacetate (SIA) in more detail and developed two protocols, which lead to peptide-protein conjugates with predefined average conjugation ratios. This holds potential to eliminate tedious and expensive optimization steps for the synthesis of a bioconjugate of optimal composition.
A new method for positioning of mobile users by comparing a time series of measured reception power levels with predictions (2004)

Many modern applications for mobile phones are based on information about the exact position of the user. There are several methods, which fulfill this task. Some require extensions of the network or the terminals; others do not, but provide little accuracy. The method presented here uses exclusively standard measurements, network parameters, and data from the network planning process. The power level measurements of the mobile reports to the network for handover and other radio resource management tasks are compared with the field strength values predicted by network planning tools. Using a single report is a well-known positioning method, which is not very accurate, because it is very sensitive to fading and other random variations of the signal levels. In the new method, a series of several reports is used. This series corresponds to a path, on which the user moves. An efficient algorithm calculates the probability of the most probable path leading to each point in the search area. The estimated position is the weighted average of all these points. Since searching the whole area of a network is not feasible in practice, the calculation effort is drastically reduced by a preprocessing step, which allows the preselection of the search area based on information about the current service cell of the user. Extensive field trials in existing GSM networks have shown that the method works well and gives substantial improvement compared to other positioning methods, such as CI/TA. An average accuracy of 130m was observed in an urban environment and about 300m in rural areas. An UTRAN provides some measurements, which are very similar to those of GSM, it is possible to apply this method in UMTS networks as well.
Prospects and Challenges of Implementing Enterprise Mobility Management Case of a Large Telecom Service Provider in United Arab Emirates (2013)

Over the last few years, there has been an exponential rise in the trend to use mobile devices within enterprises. Organizations and employees are using their smart phones and tablets to aid in work. Several organizations has introduced the concept of â€œbring your own deviceâ€ (BYOD), in order to achieve more efficiency and improved productivity. This increase in use of mobile devices, although providing benefits to the organizations, is also resulting in more effort for the information technology (IT) staff to provide support and manage these devices within the enterprise. Several organizations around the globe are implementing mobile device management (MDM) / enterprise mobility management (EMM) solutions to manage mobile devices within the organization. This study identifies the prospects and challenges in implementing EMM using a case of a large telecom service provider in United Arab Emirates (UAE).

System Accuracy Evaluation of 27 Blood Glucose Monitoring Systems According to DIN EN ISO 15197 (2010)

More than 40% of the evaluated BG monitoring systems did not fulfill the minimum accuracy requirements of DIN EN ISO 15197:2003. As inaccurate BG monitoring systems bear the risk of false treatment decisions by the diabetes patient and subsequent possible severe health injury, manufacturers should regularly and effectively check the quality of BG meters and BG test strips.
FAKEDETECTOR: Effective Fake News Detection with Deep Diffusive Neural Network (2018)

In recent years, due to the booming development of online social networks, fake news for various commercial and political purposes has been appearing in large numbers and widespread in the online world. With deceptive words, online social network users can get infected by these online fake news easily, which has brought about tremendous effects on the offline society already. An important goal in improving the trustworthiness of information in online social networks is to identify the fake news timely. This paper aims at investigating the principles, methodologies and algorithms for detecting fake news articles, creators and subjects from online social networks and evaluating the corresponding performance. This paper addresses the challenges introduced by the unknown characteristics of fake news and diverse connections among news articles, creators and subjects. This paper introduces a novel automatic fake news credibility inference model, namely FAKEDETECTOR. Based on a set of explicit and latent features extracted from the textual information, FAKEDETECTOR builds a deep diffusive network model to learn the representations of news articles, creators and subjects simultaneously. Extensive experiments have been done on a real-world fake news dataset to compare FAKEDETECTOR with several state-of-the-art models, and the experimental results have demonstrated the effectiveness of the proposed model.
Young people’s expressed needs for Comprehensive Sexuality Education in Ecuadorian schools (2017)

Este estudio analiza las necesidades de educación sexual expresadas de los jóvenes de Azuay, una región de Ecuador caracterizada por una gran proporción de jóvenes cuyos padres han emigrado al extranjero, un grupo a menudo considerado en riesgo de desarrollar problemas de salud sexual. El muestreo por conglomerados estratificado en múltiples etapas se utilizó para reclutar jóvenes de 11 y 19 años para el estudio. Se analizaron las necesidades expresadas de los participantes en relación con el género, el estado migratorio de los padres, la edad y la ubicación geográfica. Los resultados de la encuesta revelaron que los jóvenes expresaron altas necesidades con respecto a los diferentes componentes de la Educación Integral en Sexualidad: roles de género, salud sexual y reproductiva, ciudadanía sexual, placer, violencia, diversidad y relaciones. Los análisis de regresión ordinales revelaron pocas diferencias significativas en relación con las variables sociodemográficas, lo cual fue sorprendente, en particular, con respecto al grupo de jóvenes con padres migrantes. Dados los altos niveles de necesidades expresadas, los resultados tienen implicaciones importantes para el diseño e implementación de futuros programas de educación sexual.
Fever caused by hydroxyurea (1981)

• Hydroxyurea has been rarely implicated as a cause of drug fever. In this report, we describe a patient who was highly febrile while receiving hydroxyurea for psoriasis. The fever disappeared after discontinuation of therapy with this drug; however, the fever recurred when the patient received hydroxyurea again. (<i>Arch Intern Med</i>141:260-261, 1981)

Geophysical exploration with audiofrequency natural magnetic fields (1985)

Abstract Experience with the AFMAG method has demonstrated that an electromagnetic exploration system using the Earth's natural audiofrequency magnetic fields as an energy source is capable of mapping subsurface electrical structure in the upper kilometer of the Earth's crust. We resolved the limitations of this method by adapting the tensor analysis and remote reference noise bias removal techniques from the geomagnetic induction and magnetotelluric methods to computation of the tippers.After a thorough spectral study of the natural magnetic fields, we designed lightweight magnetic field sensors capable of measuring the magnetic field throughout the year. We also built a digital acquisition and processing system with the ability to provide audiofrequency tipper results in the field.This new instrumentation was used in a study of the Mariposa, California site previously mapped with AFMAG. This study once again demonstrates the usefulness of natural magnetic field data in mapping an electrically conductive body. Reoccupation of one of the sites in several different seasons proves the high level of repeatability of these data. As well as being repeatable, the tensor data provide additional information on the geometry of the conductive body. Different electrical conductivity features can be distinguished using a broad band of frequencies.
Judicial Choice and Disparities between Measures of Economic Values (2000)

This book presents the definitive exposition of 'prospect theory', a compelling alternative to the classical utility theory of choice. Building on the 1982 volume, Judgement Under Uncertainty, this book brings together seminal papers on prospect theory from economists, decision theorists, and psychologists, including the work of the late Amos Tversky, whose contributions are collected here for the first time. While remaining within a rational choice framework, prospect theory delivers more accurate, empirically verified predictions in key test cases, as well as helping to explain many complex, real-world puzzles. In this volume, it is brought to bear on phenomena as diverse as the principles of legal compensation, the equity premium puzzle in financial markets, and the number of hours that New York cab drivers choose to drive on rainy days. Theoretically elegant and empirically robust, this volume shows how prospect theory has matured into a new science of decision making.
Distribution system state estimation (1995)

A three-phase distribution system state estimation algorithm is proposed in this paper. The normal equation method is used to compute the real-time states of distribution systems modeled by their actual a-b-c phases. A current based formulation is introduced and compared with other formulations. Observability analysis for the proposed distribution system state estimation is discussed. Test results indicate that the normal equation method is applicable to the distribution system state estimation and the current based rectangular form formulation is suitable for this application.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nanocarriers with Gentamicin to Treat Intracellular Pathogens (2006)

Brucellosis is a worldwide zoonosis caused by different species of the genus Brucella. The intracellular localisation of this pathogen, particularly in macrophages, renders treatment difficult since most antibiotics known to be efficient in vitro do not actively pass through cellular membranes. As alternative to current treatment, polymeric drug delivery systems containing gentamicin have been developed. These particulate carriers target the drug into the mononuclear-phagocytic system, where the pathogen resides that will allow intracellular accumulation of the antibiotic after particle degradation. Besides, particle uptake may induce macrophage activation, increasing the production of reactive oxygen intermediates, involved in host defense against the intracellular pathogen. The aim of the present work was to study the suitability of polymeric nanoparticles for gentamicin entrapment in view to treat brucellosis. Different poly(lactide-co-glycolide) PLGA polymers were used to formulate the nanoparticles containing gentamicin by a water-oil-water solvent evaporation method. Furthermore, in vitro macrophage activation upon nanoparticles phagocytosis and in vivo distribution of the nanocarriers in the target organs for Brucella (liver and spleen) were also studied. The nanoparticle sizes were below 350 nm, the gentamicin encapsulation efficiency depended on the polymer type used for their preparation and the in vitro release of the antibiotic exhibited a continuos pattern (PLGA 502H). PLGA 502H nanoparticles were the most suitable due to the highest entrapment and the most sustained release. The nanoparticles were successfully phagocyted by a J774 murine monocytes cell line and biodistribution studies in mice after intravenous administration of the delivery systems revealed that the particles reached the target organs of Brucella (liver and spleen). All together, these results indicate that the nanocarriers described in this work may be suitable as gentamicin delivery system to control brucellosis.
Iron Complexes and Their Reactivity in the Bleomycin Assay for Radical-Promoting Loosely-Bound Iron (1986)

The sensitivity of the bleomycin assay for loosely-bound iron depends on the concentration of bleomycin and ascorbic acid and the pH of the reaction. The non-haem-iron proteins transferrin, conalbumin and ferritin release iron at an acid pH value, whereas the haem-iron proteins release iron more readily at an alkaline pH. In addition, haem proteins are liable to release iron when peroxides are present. Organic peroxides and hydrogen peroxide can be produced during the bleomycin reaction leading to iron release from haem proteins. However, this can be prevented from reacting with bleomycin by adding zinc ions to the reaction following addition of the sample. Iron already bound to bleomycin is not displaced by zinc whereas zinc bound to bleomycin is not displaced by iron allowing 'free' and 'released' iron to be discriminated.
Adaptive Multiple Importance Sampling (2012)

Abstract. The Adaptive Multiple Importance Sampling algorithm is aimed at an optimal recycling of past simulations in an iterated importance sampling (IS) scheme. The difference with earlier adaptive IS implementations like Population Monte Carlo is that the importance weights of all simulated values, past as well as present, are recomputed at each iteration, following the technique of the deterministic multiple mixture estimator of Owen & Zhou ( J. Amer. Statist. Assoc. , 95, 2000, 135). Although the convergence properties of the algorithm cannot be investigated, we demonstrate through a challenging banana shape target distribution and a population genetics example that the improvement brought by this technique is substantial.
Apoptosis. Its nature and implications for dermatopathology. (1979)

Apoptosis is a distinctive mode of cell death with characteristic morphologic features which serves as a balance to mitosis in regulating the size of animal tissues. In contrast to coagulative necrosis, the cytologic features of apoptosis suggest active self-destructive rather than progressive disintegration. It typically affects scattered individual cells which condense and bud to produce many membrane-bounded fragments in which organelles appear intact when viewed by the electron microscope. These apoptotic bodies are then phagocytosed and digested by cells resident in the tissue. Apoptosis, unlike coagulative necrosis, does not itself evoke an inflammatory response. Apoptosis is a feature of such diverse processes as deletion of phylogenetic vestiges during normal embryonic development, involution of endocrine-dependent organs after withdrawal of trophic hormones, cell-mediated immune attack on tissues, and therapeutically induced regression of neoplasms. Apoptosis has received scant attention in dermatopathology. However, it is now known to be an important feature of lichen planus, certain drug eruptions, the skin lesions of graft-versus-host reactions, the regression of plane warts, and the effects of ultraviolet damage. It is also involved in the kinetics of cutaneous neoplasms. In some of these situations, apoptotic bodies have, in the past, been given names such as Civatte bodies, colloid bodies, single-cell necrobiosis, sunburn cells, and dyskeratotic cells without their basic nature having been recognized.
