Infant Feeding Practices and Their Possible Relationship to the Etiology of Diabetes Mellitus

1. Insulin-dependent diabetes mellitus develops within a group of individuals who carry specific diabetes susceptibility traits. Because all of the potential diabetes "susceptibility genes" are not known, currently it is not possible to identify all individuals at risk. It appears, however, that a small percentage of such individuals will ever develop clinical diabetes mellitus. 2. The autoimmune destructive process may be triggered by a number of environmental events. 3. Early exposure of infants to cow's milk protein may be an important factor in the initiation of the β cell destructive process in some individuals. It is not known whether the cow's milk protein in commercially available infant formulas is associated with this process. 4. The avoidance of cow's milk protein for the first several months of life may reduce the later development of IDDM or delay its onset in susceptible individuals. 5. Research directed toward further defining the possible relationship between infant feeding practices and the development of IDDM is needed.
Detecção e Aplicação de Dependências de Dados

Dependências de dados são fundamentais em importantes áreas do gerenciamento de dados, tais como qualidade, integração e análise de dados. Esta tese apresenta contribuições relevantes para importantes problemas relacionados à tais dependências. O primeiro é relacionado à detecção de dependências. Estudamos a detecção de restrições de negação, pois elas generalizam outros tipos de dependências, e conseguem expressar complexas regras de qualidade de dados. Apresentamos um algoritmo para a descoberta de restrições de negação e o avaliamos em uma variedade de cenários. Em comparação com soluções do estado da arte, nosso algoritmo melhora significativamente a eficiência da detecção em termos de tempo de execução. O segundo problema diz respeito à aplicação de dependências na melhoria da consistência de dados. Mostramos que é possível extrair evidências de conjuntos de dados para descobrir restrições que se mantêm aproximadamente e que identificam, com boa precisão e recuperação, inconsistências no conjunto de dados de entrada. Apresentamos, ainda, um sistema para detecção de erros baseados em restrições de negação que apresenta execuções até três ordens de magnitude mais rápidas do que as de soluções do estado da arte, especialmente para conjuntos de dados maiores e restrições complexas. Por fim, nossa última contribuição é sobre a aplicação de dependências na otimização de consultas. Apresentamos um sistema para a detecção e seleção automática de dependências funcionais baseado em representações extraídas das cargas de trabalho. Nossos experimentos mostram que a aplicação das dependências selecionadas pode reduzir o tempo de resposta geral de diversas consultas. As contribuições acima foram publicadas em veículos de renome nacional (SBBD) e internacional (PVLDB, CIKM e DEXA), e possibilitaram cooperação nacional com universidades federais (UFPR e UTFPR), bem como internacional com institutos de pesquisa (HPI-Alemanha e SnT-Luxemburgo).

Evaluation of feeder monitoring parameters for incipient fault detection using Laplace trend statistic

This paper focuses on a systematic and cumulative statistical approach for identifying symptom parameters of incipient faults in distribution feeders. The proposed method aims to provide a tool for evaluating and identifying the best and highly correlated parameters to the faults so that they could be used for incipient fault detection and feeder condition monitoring. Laplace test statistic is adopted for trend analysis of the event log of candidate parameters and applied to actual feeder event data for on-line detection and monitoring purpose.
Combination of Symptom Profile, Endoscopic Findings, and Esophageal Mucosal Histopathology Helps to Differentiate Achalasia from Refractory Gastroesophageal Reflux Disease

Achalasia, a rare primary esophageal motility disorder, is often misdiagnosed as refractory gastroesophageal reflux disease (GERD). This study is aimed to identify the clinical and histopathologic features that may help to differentiate these two entities. Patients with untreated achalasia and those with refractory reflux symptoms despite ≥8 weeks of proton-pump inhibitor treatment were enrolled prospectively. All patients underwent validated symptom questionnaires, esophagogastroduodenoscopy with biopsy, and high-resolution impedance manometry (HRIM). Histopathology of esophageal mucosa was compared based on four pre-determined histological criteria: basal cell hyperplasia or papillae elongation, eosinophilic infiltration, petechiae formation, and hypertrophy of the muscularis mucosae (MM). Compared with the GERD patients, patients with achalasia had similar reflux symptoms, but higher Eckardt scores, fewer erosive esophagitis and hiatal hernia, more esophageal food retention on endoscopy, and higher prevalence of hypertrophy of the MM and petechiae formation on histopathology. Multivariate logistic regression based on Eckardt score ≥4, normal esophagogastric junction morphology or esophageal food retention, and coexistence of petechiae formation and hypertrophy of the MM, established the best prediction model for achalasia. Therefore, combination of routinely accessible variables, including Eckardt score, endoscopic features, and histopathology obtained via esophageal mucosal biopsy, may provide an earlier identification of achalasia.
Detection and self-healing of cluster breakages in mines and tunnels: an empirical investigation

Purpose – The study aims at providing a reliable system of real-time monitoring for underground mine and tunnels which detects any structural change in the network and reconfigures it for resuming the data delivery process. In high stress environments, e.g. underground mines and tunnels, real-time activity monitoring is an emerging issue. Wireless sensor networks (WSNs) play a key role in ensuring the safety of people working in underground mines and tunnels. WSN not only provide real-time monitoring of underground environment but also detects any structural change in the network itself. Design/methodology/approach – In this paper, results of empirical implementation of a re-configurable WSN, capable of self-healing approach, reconfigure the network connectivity upon failure or addition of nodes in the system. An open-source radio-frequency identification standard for WSN, named as DASH7, is used for practical implementation. The proposed system is capable of determining cluster breakage by sudden disrupt.
Thermolab: A Thermodynamics Laboratory for Nonlinear Transport Processes in Open Systems

We developed a numerical thermodynamics laboratory called “Thermolab” to study the effects of the thermodynamic behavior of nonideal solution models on reactive transport processes in open systems. The equations of the state of internally consistent thermodynamic data sets are implemented in MATLAB functions and form the basis for calculating Gibbs energy. A linear algebraic approach is used in Thermolab to compute Gibbs energy of mixing for multicomponent phases to study the impact of the nonideality of solution models on transport processes. The Gibbs energies are benchmarked with experimental data, phase diagrams, and other thermodynamic software. Constrained Gibbs minimization is exemplified with MATLAB codes and iterative refinement of composition of mixtures may be used to increase precision and accuracy. All needed transport variables such as densities, phase compositions, and chemical potentials are obtained from Gibbs energy of the stable phases after the minimization in Thermolab. We demonstrate the use of precomputed local equilibrium data obtained with Thermolab in reactive transport models. In reactive fluid flow the shape and the velocity of the reaction front vary depending on the nonlinearity of the partitioning of a component in fluid and solid. We argue that nonideality of solution models has to be taken into account and further explored in reactive transport models. Thermolab Gibbs energies can be used in Cahn‐Hilliard models for nonlinear diffusion and phase growth. This presents a transient process toward equilibrium and avoids computational problems arising during precomputing of equilibrium data.
Textile UWB Antenna Bending and Wet Performances

The vision and ideas of wearable computing systems describe future electronic systems as an integral part of our everyday clothing that provides the wearer with such intelligent personal assistants. Recently, there has been growing interest in the antenna community to merge between wearable systems technology, ultrawideband (UWB) technology and textile technology. This work aimed to make closer steps towards real wearability by investigating the possibilities of designing wearable UWB antenna where textile materials are used for the substrate as well as the conducting parts of the designed antenna. Two types of conducting materials have been used for conducting parts, while a nonconducting fabric has been used as antenna substrate material. A set of comparative results of the proposed design were presented and discussed. Moreover, effects on the return loss by means of measurements for each fabricated antenna prototype under bent and fully wet conditions were discussed in more details.
Ripening mechanism of astringent persimmon by ethylene under cold storage

ABSTRACT The mechanism of ripening and the expression of ethylene response genes of astringent persimmon (Diospyros kaki L.f.) treated with ethylene at different times during cold storage has been investigated. Freshly harvested fruit was stored at 0°C and 85% relative humidity for up to 2 months, and treated with 100 µL L −1 ethylene at 0, 1, and 2 months. The ethylene treatment was proceeding at 25°C until 4 d. Ethylene production patterns were similar in fruit from the ethylene treatment regardless of the treatment time point, but maximum ethylene production occurred earlier with longer storage periods. Softening of ethylene treated fruit was more rapid after storage than at harvest. Although the reduction of soluble tannin was similar in fruit from all ethylene treatments, it was faster with longer storage periods. Expression of DKEIL, DKERF3, DKERF5, and DKERF8 transcript levels was higher in stored fruit than at harvest. The results of this study suggest that the astringency removal and ripening of cold stored persimmon fruit could be accelerated by 1–2 d compared with ripening at harvest.
Performance enhancement of Salisbury screen absorber using resistively loaded spiral FSS

In this article, we show that the −10 dB reflectivity bandwidth of a Salisbury screen operating at normal incidence is increased by 56% when a lossy spiral shaped frequency selective surface is inserted between the outermost 377 Ω per square resistive sheet and the ground plane. Moreover, this structure exhibits significantly better angular stability and is suitable for suppressing radar backscatter simultaneously in the TE and TM plane. Reflectivity predictions for normal and 40° incidence are shown to be in close agreement with bistatic measured results over the frequency range 5.4–18 GHz. © 2011 Wiley Periodicals, Inc.

Damage Detection from SAR Imagery: Application to the 2003 Algeria and 2007 Peru Earthquakes

This paper is focused on the improvement and further validation of a recently proposed approach for the joint use of radar satellite imagery of an area affected by a major disaster and ancillary data. The study was carried out at different sites on imagery of two different earthquakes occurred one in the Mediterranean coast of Algeria on May 21st, 2003, which severely affected the city of Boumerdes, and one in the Pacific Coast of Peru on August, 15th, 2007. The combination of different radar-extracted features results in very fuzzy classification of the damage patterns, far less detailed than what available using optical imagery. However, focused results using the above-mentioned ancillary data provide enough detail and precision to be comparable with them. In particular, quantized damage level at the block level is achieved at enough detail using ALOS/PALSAR data and thus validates the original idea.
BULK REFRIGERATION OF FRUITS AND VEGETABLES PART I: THEORETICAL CONSIDERATIONS OF HEAT AND MASS TRANSFER

A computer algorithm was developed that estimates the latent and sensible heat loads due to the bulk refrigeration of fruits and vegetables. The algorithm also predicts the commodity moisture loss and temperature distribution which occurs during refrigeration. This algorithm includes the combined phenomena of transpiration, respiration, air flow, and convective heat and mass transfer. The development and performance of the computer algorithm are presented in two parts. This paper, Part I, discusses commodity thermophysical properties and flowfield parameters which govern the heat and mass transfer from fruits and vegetables. Commodity thermophysical properties include transpiration and respiration, while flowfield parameters include psychrometric properties and convective heat and mass transfer coefficients. Part I describes the modeling treatment of these properties and parameters. The second paper, Part II, discusses the heat and mass transfer models, compares algorithm results to experimental data, and.
Stray capacitances of two winding transformers: equivalent circuit, measurements, calculation and lowering

As long as it works linearly, a two winding transformer is, from an electrostatic point of view, a three port system. Its capacitance matrix includes six independent values. Consequently, whatever its shape, introducing six capacitances in the right places of the equivalent circuit allows the user to account for the whole electrostatic behaviour of this component. With such an equivalent circuit, resonance frequencies can be computed and, reversely, the six capacitances are all deducible from measured resonance frequencies. Thus, using this circuit by hand or by software, interwinding currents of real electronic circuits can be forecasted together with parasitic resonances related to the transformer. After this global approach, a microscopic approach is adopted. A closer look at the winding layer shape and then, at the wire shape itself leads to two simple models which allow the six capacitances of the equivalent circuit to be computed by hand. Values found are approximate but, thanks to analytical expressions, two design rules leading to lower capacitance values are inferred. Measurements are presented to establish the reliability of the equivalent circuit and to evaluate the interest of the proposed designing rules. <<ETX>>
The 3He Supply Problem

One of the main uses for 3He is in gas proportional counters for neutron detection. Radiation portal monitors deployed for homeland security and non-proliferation use such detectors. Other uses of 3He are for research detectors, commercial instruments, well logging detectors, dilution refrigerators, for targets or cooling in nuclear research, and for basic research in condensed matter physics. The US supply of 3He comes almost entirely from the decay of tritium used in nuclear weapons by the US and Russia. A few other countries contribute a small amount to the world’s 3He supply. Due to the large increase in use of 3He for homeland security, the supply has dwindled, and can no longer meet the demand. This white paper reviews the problems of supply, utilization, and alternatives.
Optimisation of Thin and Thick Film Technology for Hybrid MicrowaveCircuits

In the last ten to fifteen years the development of microstrip techniques has made a great step forward. After the first theoretical analyses given during the early fifties, 1-a investigations about field distribution, mode conditions and dispersion characteristics were carried out with great success. One could say that the theoretical treatment of microstrip is almost complete. Nearly all components formerly built in waveguideor coaxial-technique, for example, oscillators, mixers, directional couplers, and filters, even entire units like doppler radar modules are now being built, using microstrip technique. There are several different methods of realizing microstrip circuits. Each technology, e.g. thinfilm, thickfilm, has its own advantages and disadvantages for hybrid microwave technology. This can be in costs, reliability, Q-factor or other special requirements. Three special technologies should be compared in regard to their application for microwave circuits: thickfilm, thinfilm, chemical metallisation (CMS). Most of the features that are necessary for lower frequencies, like surface flatness or edge accuracy, apply in the microwave field as well. The most critical additional demand is that of low losses. The origin of losses are the loss tangent of the substrate material, conductor losses, surface roughness and high surface current density of the strip due to the strip manufacturing process as well as adhesion layers with poor electrical performance. Radiation losses must also be regarded. Dielectric losses are determined by the choice of the substrate material. In order to show the importance of this choice for the resulting technical performance of the hybrid device, especially for the frequency range up to 16 GHz, Figure presents a
Vertical N-channel MOSFETs for extremely high density memories: the impact of interface orientation on device performance

We investigate vertical n-channel MOSFETs fabricated at the sidewalls of etched trenches. In general, these sidewalls can be nonplanar and incorporate different crystallographic orientations. Therefore, it is necessary to involve models for a variety of interface orientations in order to describe scaled-down vertical devices. However, the crystallographic orientation of the interface has a strong impact on crucial device parameters such as gate oxide thickness, carrier mobility, and interface trap density. For the first time, in this work a complete set of these parameters is investigated systematically for a wide range of different crystallographic orientations. Based on these parameters, the modeling of vertical MOSFETs featuring a cylindrical geometry is demonstrated and verified by measurements. Furthermore, differences observed between vertical and planar devices of equal parameters are deduced from interface properties related to the orientation of the sidewall.
Automating Emulator Construction for Geophysical Hazard Maps

This paper describes an efficient and systematic process for using geophysical computer model simulations to guide efforts in probabilistic hazard mapping. The framework being proposed requires the simultaneous construction of many ($10^2$--$10^4$) statistical emulators, e.g., cheap model surrogates. This paper describes an automation process for choosing designs for and fitting these emulators. Throughout the description of this process, several useful modifications to standard emulators are explored. Additionally, this approach enables a fast and flexible uncertainty quantification for multiple sources of aleatory variability (natural randomness) and epistemic uncertainty (uncertainty in geophysical and statistical models) in the context of probabilistic hazard mapping. This process is illustrated through an application to granular volcanic flows.
Real-time qualitative analysis of the temporal shapes of (bio) process variables

One of the limitations of today's knowledge-based (KB) systems for diagnostics and supervision is a lack of adequate temporal reasoning mechanisms. Most of these systems are designed primarily to operate with the current values of the process variables and, sometimes, with their derivatives. Such simple capabilities, however, are not always sufficient to identify some complex dynamic phenomena, which in many cases leave their own unique “stamp” on the process behavior, expressed in the form of characteristic temporal shapes of the related variables. To detect and diagnose adequately the events of interest, the KB system should be able to reason about the temporal shapes of the process variables. Although during manual supervision process operators rely heavily on such characteristic shapes as reliable symptoms of underlying phenomena, their exploitation has not been considered seriously by the designers of KB control systems. We propose a generic methodology for qualitative analysis of the temporal shapes of continuous process variables designed to be embedded into a real-time KB environment. It is applicable to bioprocesses, as well as to other complex dynamic systems.

A 7‐inch VGA transmissive‐type active matrix TFT‐LCD display with a‐Si TFT fabricated on colorless polyimide (PI) substrate is demonstrated. The proposed colorless PI substrate has the features of high Tg (∼350 °C) and high light transmittance (∼90%). The electrical and mechanical reliability for a‐Si TFT fabricated at 200 °C have also been studied.
Production of Asphalt-Rubber Binders by High-Cure Conditions

A curing study was undertaken to determine the effect that asphalt composition, rubber content, rubber mesh size, curing time, curing temperature, and rate of mixing have on asphalt-rubber properties. Curing temperatures of 232°C or 260°C (450°F or 500°F) and a high-shear laboratory mixer were used to produce the asphalt-rubber blends. The properties studied were rubber dissolution; rubber settling; molecular weight distribution; and low-, intermediate-, and high-temperature rheological properties. Increasing the curing temperature from 232°C to 260°C (450°F to 500°F) drastically increased the rate of devulcanization and depolymerization of the rubber, whereas increasing the rate of mixing from 4,000 rpm to 8,000 rpm drastically decreased the settling rate of rubber in a binder. Lower-molecular-weight asphalts were better at devulcanizing the rubber; higher-molecular-weight asphalts were better at depolymerizing the rubber. These high-cure binders are homogeneous in appearance and slow to phase separate on standing; they have acceptable compaction viscosities at hot-mix temperatures, higher G*/sinδ at rutting temperatures, and lower stiffness at cold temperatures than does the base asphalt.
