    Cross, James H., II

    1995-01-01

    The GRASP/Ada project (Graphical Representations of Algorithms, Structures, and Processes for Ada) has successfully created and prototyped a new algorithmic level graphical representation for Ada software, the Control Structure Diagram (CSD). The primary impetus for creation of the CSD was to improve the comprehension efficiency of Ada software and, as a result, improve reliability and reduce costs. The emphasis has been on the automatic generation of the CSD from Ada PDL or source code to support reverse engineering and maintenance. The CSD has the potential to replace traditional prettyprinted Ada Source code. A new Motif compliant graphical user interface has been developed for the GRASP/Ada prototype.

  14. The AdaBoost Flow

    CERN Document Server

    Lykov, A; Vaninsky, K

    2011-01-01

    We introduce a dynamical system which we call the AdaBoost flow. The flow is defined by a system of ODEs with control. We show how by a suitable choice of control AdaBoost algorithm of Schapire and Freund and arc-gv algorithm of Breiman can be embedded in the AdaBoost flow. We also show how previously studied by Schapire and Singer confidence rated prediction can be obtained from our continuous time approach. We introduce a new continuous time algorithm which we call superBoost and describe its properties. The AdaBoost flow equations coincide with the equations of dynamics of the nonperiodic Toda system written in terms of spectral variables. This establishes a connection between two seemingly unrelated fields of boosting algorithms and classical integrable models. Finally we explain similarity of the AdaBoost flow with Perelman's ideas to control Ricci flow.

  4. Paranoia.Ada: A diagnostic program to evaluate Ada floating-point arithmetic

    Science.gov (United States)

    Hjermstad, Chris

    1986-01-01

    Many essential software functions in the mission critical computer resource application domain depend on floating point arithmetic. Numerically intensive functions associated with the Space Station project, such as emphemeris generation or the implementation of Kalman filters, are likely to employ the floating point facilities of Ada. Paranoia.Ada appears to be a valuabe program to insure that Ada environments and their underlying hardware exhibit the precision and correctness required to satisfy mission computational requirements. As a diagnostic tool, Paranoia.Ada reveals many essential characteristics of an Ada floating point implementation. Equipped with such knowledge, programmers need not tremble before the complex task of floating point computation.

  5. A small evaluation suite for Ada compilers

    Wilke, Randy; Roy, Daniel M.

    1986-01-01

    After completing a small Ada pilot project (OCC simulator) for the Multi Satellite Operations Control Center (MSOCC) at Goddard last year, the use of Ada to develop OCCs was recommended. To help MSOCC transition toward Ada, a suite of about 100 evaluation programs was developed which can be used to assess Ada compilers. These programs compare the overall quality of the compilation system, compare the relative efficiencies of the compilers and the environments in which they work, and compare the size and execution speed of generated machine code. Another goal of the benchmark software was to provide MSOCC system developers with rough timing estimates for the purpose of predicting performance of future systems written in Ada.

    1988-01-01

    Software Engineering and Ada Database (SEAD) was developed to provide an information resource to NASA and NASA contractors with respect to Ada-based resources and activities which are available or underway either in NASA or elsewhere in the worldwide Ada community. The sharing of such information will reduce duplication of effort while improving quality in the development of future software systems. SEAD data is organized into five major areas: information regarding education and training resources which are relevant to the life cycle of Ada-based software engineering projects such as those in the Space Station program; research publications relevant to NASA projects such as the Space Station Program and conferences relating to Ada technology; the latest progress reports on Ada projects completed or in progress both within NASA and throughout the free world; Ada compilers and other commercial products that support Ada software development; and reusable Ada components generated both within NASA and from elsewhere in the free world. This classified listing of reusable components shall include descriptions of tools, libraries, and other components of interest to NASA. Sources for the data include technical newletters and periodicals, conference proceedings, the Ada Information Clearinghouse, product vendors, and project sponsors and contractors.

  12. An Embedded Rule-Based Diagnostic Expert System in Ada

    Science.gov (United States)

    Jones, Robert E.; Liberman, Eugene M.

    1992-01-01

    Ada is becoming an increasingly popular programming language for large Government-funded software projects. Ada with it portability, transportability, and maintainability lends itself well to today's complex programming environment. In addition, expert systems have also assumed a growing role in providing human-like reasoning capability expertise for computer systems. The integration is discussed of expert system technology with Ada programming language, especially a rule-based expert system using an ART-Ada (Automated Reasoning Tool for Ada) system shell. NASA Lewis was chosen as a beta test site for ART-Ada. The test was conducted by implementing the existing Autonomous Power EXpert System (APEX), a Lisp-based power expert system, in ART-Ada. Three components, the rule-based expert systems, a graphics user interface, and communications software make up SMART-Ada (Systems fault Management with ART-Ada). The rules were written in the ART-Ada development environment and converted to Ada source code. The graphics interface was developed with the Transportable Application Environment (TAE) Plus, which generates Ada source code to control graphics images. SMART-Ada communicates with a remote host to obtain either simulated or real data. The Ada source code generated with ART-Ada, TAE Plus, and communications code was incorporated into an Ada expert system that reads the data from a power distribution test bed, applies the rule to determine a fault, if one exists, and graphically displays it on the screen. The main objective, to conduct a beta test on the ART-Ada rule-based expert system shell, was achieved. The system is operational. New Ada tools will assist in future successful projects. ART-Ada is one such tool and is a viable alternative to the straight Ada code when an application requires a rule-based or knowledge-based approach.

  13. Transformation of ADA programs into silicon

    Science.gov (United States)

    Organick, E. I.; Lindstrom, G.; Smith, D. K.; Subrahmany; Carter, T.

    1982-03-01

    This report outlines the beginning steps taken in an integrated research effort toward the development of a methodology, and supporting systems, for transforming Ada programs, or program units, (directly) into corresponding VLSI systems. The time seems right to expect good results. The need is evident; special purpose systems should be realistic alternatives where simplicity, speed, reliability, and security ae dominant factors. Success in this research can lead to attractive options for embedded system applications. Ada programs can be regarded as ensembles of machines, one per program unit (module), which in turn may be mapped directly into corresponding VLSI structures on one or more chips with interconnecting (packet switched or other) communication nets. The research reported here is part of a five-year plan, the first year of which focuses on 'proving' the concepts through a realistic demonstration of methodology for a specific example Ada program (a silicon representation of part or all of the DoD Standard Internet Protocol, IP, initially expressed in Ada). Implicit in these objectives is the development of a set of hardware structuring paradigms (rewrite rules) whose application can ensure that transformation steps between levels of abstraction in the design process are well structured in order to preserve the integrity and, where possible, the clarity of the original Ada specification. Some paradigms, but of course not all, lead to highly efficient implementations.

  14. A database management capability for Ada

    1986-01-01

    The data requirements of mission critical defense systems have been increasing dramatically. Command and control, intelligence, logistics, and even weapons systems are being required to integrate, process, and share ever increasing volumes of information. To meet this need, systems are now being specified that incorporate data base management subsystems for handling storage and retrieval of information. It is expected that a large number of the next generation of mission critical systems will contain embedded data base management systems. Since the use of Ada has been mandated for most of these systems, it is important to address the issues of providing data base management capabilities that can be closely coupled with Ada. A comprehensive distributed data base management project has been investigated. The key deliverables of this project are three closely related prototype systems implemented in Ada. These three systems are discussed.

  8. Object-oriented programming with mixins in Ada

    Science.gov (United States)

    Seidewitz, ED

    1992-01-01

    Recently, I wrote a paper discussing the lack of 'true' object-oriented programming language features in Ada 83, why one might desire them in Ada, and how they might be added in Ada 9X. The approach I took in this paper was to build the new object-oriented features of Ada 9X as much as possible on the basic constructs and philosophy of Ada 83. The object-oriented features proposed for Ada 9X, while different in detail, are based on the same kind of approach. Further consideration of this approach led me on a long reflection on the nature of object-oriented programming and its application to Ada. The results of this reflection, presented in this paper, show how a fairly natural object-oriented style can indeed be developed even in Ada 83. The exercise of developing this style is useful for at least three reasons: (1) it provides a useful style for programming object-oriented applications in Ada 83 until new features become available with Ada 9X; (2) it demystifies many of the mechanisms that seem to be 'magic' in most object-oriented programming languages by making them explicit; and (3) it points out areas that are and are not in need of change in Ada 83 to make object-oriented programming more natural in Ada 9X. In the next four sections I will address in turn the issues of object-oriented classes, mixins, self-reference and supertyping. The presentation is through a sequence of examples. This results in some overlap with that paper, but all the examples in the present paper are written entirely in Ada 83. I will return to considerations for Ada 9X in the last section of the paper.

    Adenosine deaminase-1 (ADA1) regulates the concentration of adenosine as the main modulator of oocyte maturation. There is compelling evidence for the association of ADA1 gene polymorphisms with many diseases but the importance of ADA1 polymorphisms in polycystic ovary syndrome (PCOS) has not been studied before. This study investigates serum total ADA activity (tADA), ADA1 and ADA2 isoenzyme activities, and genotype and allele frequencies of G22A and A4223C polymorphisms in healthy and PCOS women. In this case-control study 200 PCOS patients and 200 healthy women were enrolled. Genomic DNA was extracted from whole blood and the PCR-RFLP technique was used to determine the G22A and A4223C variants. The genotype frequencies were calculated and the association between polymorphic genotypes and enzyme activities were determined. tADA activity was significantly lower in the PCOS group compared with the control group (27.76±6.0 vs. 39.63±7.48, respectively). PCOS patients also showed reduced activity of ADA1 and ADA2. PCOS was not associated with G22A polymorphism whereas AA, AC, and CC genotypes of A4223C polymorphism were found distributed differently between the control and the PCOS women where the C allele showed a strong protective role for PCOS (odds ratio=1.876, p=0.033). The present study for the first time showed that lower ADA activity may be involved in pathogenesis of PCOS by maintaining a higher concentration of adenosine affecting follicular growth. As a novel finding, we also showed great differences in genotype distribution and allele frequencies of A4223C polymorphism between groups indicating a protective role for C allele against PCOS.

    The use of the Ada language and design methodologies that encourage full use of its capabilities have a strong impact on all phases of the software development project life cycle. At the National Aeronautics and Space Administration/Goddard Space Flight Center (NASA/GSFC), the Software Engineering Laboratory (SEL) conducted an experiment in parallel development of two flight dynamics systems in FORTRAN and Ada. The differences observed during the implementation, unit testing, and integration phases of the two projects are described and the lessons learned during the implementation phase of the Ada development are outlined. Included are recommendations for future Ada development projects.

    JPL is under contract, through NASA, with the US Army to develop a state-of-the-art Command Center System for the US European Command (USEUCOM). The Command Center System will receive, process, and integrate force status information from various sources and provide this integrated information to staff officers and decision makers in a format designed to enhance user comprehension and utility. The system is based on distributed workstation class microcomputers, VAX- and SUN-based data servers, and interfaces to existing military mainframe systems and communication networks. JPL is developing the Command Center System utilizing an incremental delivery methodology called the Rapid Development Methodology with adherence to government and industry standards including the UNIX operating system, X Windows, OSF/Motif, and the Ada programming language. Through a combination of software engineering techniques specific to the Ada programming language and the Rapid Development Approach, JPL was able to deliver capability to the military user incrementally, with comparable quality and improved economies of projects developed under more traditional software intensive system implementation methodologies.

    ADAS, the Asiago-DLR Asteroid Survey, is a joint program between the Department of Astronomy and Astronomical Observatory of Padova and the DLR Berlin, dedicated to the search of asteroids. The observations are made with a 67/92 cm Schmidt Telescope on Cima Ekar, near Asiago, in northern Italy. A 2K×2K CCD camera provided by the DLR is in use, mostly in Time Delay Integration mode. The camera has a field of 0.67 square degrees and can reach a limiting magnitude V ~ 21.0 in 3 minutes of exposure time. Specific search programs, in particular for objects permanently inside the orbit of the Earth (IEOs), have been started. A simulation of the performance of the IEO survey based on the model population from Bottke et al. shows that the discovery of a one-digit number of IEOs may be possible with the layout and equipment of the ADAS survey with a couple of years of operation.

  19. Transferring data objects: A focused Ada investigation

    Science.gov (United States)

    Legrand, Sue

    1988-01-01

    The use of the Ada language does not guarantee that data objects will be in the same form or have the same value after they have been stored or transferred to another system. There are too many possible variables in such things as the formats used and other protocol conditions. Differences may occur at many different levels of support. These include program level, object level, application level, and system level. A standard language is only one aspect of making a complex system completely homogeneous. Many components must be standardized and the various standards must be integrated. The principal issues in providing for interaction between systems are of exchanging files and data objects between systems which may not be compatible in terms of their host computer, operating system or other factors. A typical resolution of the problem of invalidating data involves at least a common external form, for data objects and for representing the relationships and attributes of data collections. Some of the issues dealing with the transfer of data are listed and consideration is given on how these issues may be handled in the Ada language.

  1. Fine-Tuning ADAS Algorithm Parameters for Optimizing Traffic ...

    Science.gov (United States)

    With the development of the Connected Vehicle technology that facilitates wirelessly communication among vehicles and road-side infrastructure, the Advanced Driver Assistance Systems (ADAS) can be adopted as an effective tool for accelerating traffic safety and mobility optimization at various highway facilities. To this end, the traffic management centers identify the optimal ADAS algorithm parameter set that enables the maximum improvement of the traffic safety and mobility performance, and broadcast the optimal parameter set wirelessly to individual ADAS-equipped vehicles. After adopting the optimal parameter set, the ADAS-equipped drivers become active agents in the traffic stream that work collectively and consistently to prevent traffic conflicts, lower the intensity of traffic disturbances, and suppress the development of traffic oscillations into heavy traffic jams. Successful implementation of this objective requires the analysis capability of capturing the impact of the ADAS on driving behaviors, and measuring traffic safety and mobility performance under the influence of the ADAS. To address this challenge, this research proposes a synthetic methodology that incorporates the ADAS-affected driving behavior modeling and state-of-the-art microscopic traffic flow modeling into a virtually simulated environment. Building on such an environment, the optimal ADAS algorithm parameter set is identified through an optimization programming framework to enable th

    A service dog is defined as "any dog that is individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability." Some psychiatric patients may depend on a service dog for day-to-day functioning. The Americans with Disabilities Act (ADA) established certain rights and responsibilities for individuals with disabilities and health care providers. Psychiatric hospitalization of a patient with a service dog may pose a problem and involves balancing the requirement to provide safe and appropriate psychiatric care with the rights of individuals with disabilities. This Open Forum examines issues that arise in such circumstances, reviews the literature, and provides a foundation for the development of policies and procedures.

  5. Visualization design and verification of Ada tasking using timing diagrams

    Vidale, R. F.; Szulewski, P. A.; Weiss, J. B.

    1986-01-01

    The use of timing diagrams is recommended in the design and testing of multi-task Ada programs. By displaying the task states vs. time, timing diagrams can portray the simultaneous threads of data flow and control which characterize tasking programs. This description of the system's dynamic behavior from conception to testing is a necessary adjunct to other graphical techniques, such as structure charts, which essentially give a static view of the system. A series of steps is recommended which incorporates timing diagrams into the design process. Finally, a description is provided of a prototype Ada Execution Analyzer (AEA) which automates the production of timing diagrams from VAX/Ada debugger output.

    Brown, David B.

    1990-01-01

    The results of research and development efforts are described for Task one, Phase two of a general project entitled The Development of a Program Analysis Environment for Ada. The scope of this task includes the design and development of a prototype system for testing Ada software modules at the unit level. The system is called Query Utility Environment for Software Testing of Ada (QUEST/Ada). The prototype for condition coverage provides a platform that implements expert system interaction with program testing. The expert system can modify data in the instrument source code in order to achieve coverage goals. Given this initial prototype, it is possible to evaluate the rule base in order to develop improved rules for test case generation. The goals of Phase two are the following: (1) to continue to develop and improve the current user interface to support the other goals of this research effort (i.e., those related to improved testing efficiency and increased code reliable); (2) to develop and empirically evaluate a succession of alternative rule bases for the test case generator such that the expert system achieves coverage in a more efficient manner; and (3) to extend the concepts of the current test environment to address the issues of Ada concurrency.

    The present paper focuses upon those aspects of the Ada language whose purpose is to support the discipline of software engineering. It illustrates the use of Ada features for various forms of abstraction, separate compilation, exception handling and tasking and highlights the importance of separating the definition of a module interface from its implementation. It demonstrates the use of the package concept to realize information hiding, data encapsulation and abstract data types. Some key aspects of Ada numerics are dealt with briefly. The paper continues by providing an overview of the Ada programming environments, their history and their relationship to the CAIS interface. Finally, the special importance of the interactive debugger within such an environment is presented.

    Two important considerations that precede the design of Ada reusable packages (commonality and programming standards) are discuessed. First, the importance of designing packages to yield widespread commonality is expressed. A means of measuring the degree of applicability of packages both within and across applications areas is presented. Design consideration that will improve commonality are also discussed. Second, considerations for the development of programming standards are set forth. These considerations will lead to standards that will improve the reusability of Ada packages.

    Full Text Available Cada vez cobra más fuerza la clasificación de las drogas que las divide en psictrópicos y estupefacientes y en Costa Rica se ha añadido la sustancia inhalable. Se hace una ligera definición sobre lo que es una droga y la diferencia con las sustancias indispensables para el organismo como son el agua, el oxígeno y los alimentos las cuales son necesarias para el mismo. En el mundo cada vez es mayor el número de estas sustancias fiscalizadas, y que es considerada una acción delictiva en determinadas ocasiones. Convenios internacionales que deben ser ratificados por las naciones exige que se especifique previamente el objeto material del Delito. Las Drogas Diseñadas son aquellas que por algún cambio realizado en un laboratorio sobre su molécula, tienen los efectos muchas veces superiores a la droga madre, pero que por no estar en la lista de drogas fiscalizadas en el momento de aparición de la misma, va permitiendo que, mientras se agrega a la lista de las mencionadas drogas fiscalizadas, estos actos queden impunes con gran daño por la Salud Pública y del individuo durante mucho tiempo. Costa Rica no escapa de esta realidad por lo que el "narcotraficante" siempre irá adelante con nuevas drogas diseñadas causando grandes estragos, mientras las mismas poco a poco se van incluyendo en la lista de sustancias fiscalizadas.

    Resurfacing of urban roads with concurrent repairs and replacement of sections of curb and sidewalk may require pedestrian ramps that are compliant with the American Disabilities Act (ADA), and when street drains are in close proximity to the walkway, ADA compliant street grates may also be required. The Minnesota Department of Transportation ADA Operations Unit identified a foundry with an available grate that meets ADA requirements. Argonne National Laboratory’s Transportation Research and Analysis Computing Center used full scale three dimensional computational fluid dynamics to determine the performance of the ADA compliant grate and compared it to that of a standard vane grate. Analysis of a parametric set of cases was carried out, including variation in longitudinal, gutter, and cross street slopes and the water spread from the curb. The performance of the grates was characterized by the fraction of the total volume flow approaching the grate from the upstream that was captured by the grate and diverted into the catch basin. The fraction of the total flow entering over the grate from the side and the fraction of flow directly over a grate diverted into the catch basin were also quantities of interest that aid in understanding the differences in performance of the grates. The ADA compliant grate performance lagged that of the vane grate, increasingly so as upstream Reynolds number increased. The major factor leading to the performance difference between the two grates was the fraction of flow directly over the grates that is captured by the grates.

    The purpose of this study was to estimate and examine ways to improve the reliability of change scores on the Alzheimer's Disease Assessment Scale, Cognitive Subtest (ADAS-Cog). The sample, provided by the Alzheimer's Disease Neuroimaging Initiative, included individuals with Alzheimer's disease (AD) (n = 153) and individuals with mild cognitive impairment (MCI) (n = 352). All participants were administered the ADAS-Cog at baseline and 1 year, and change scores were calculated as the difference in scores over the 1-year period. Three types of change score reliabilities were estimated using multivariate generalizability. Two methods to increase change score reliability were evaluated: reweighting the subtests of the scale and adding more subtests. Reliability of ADAS-Cog change scores over 1 year was low for both the AD sample (ranging from .53 to .64) and the MCI sample (.39 to .61). Reweighting the change scores from the AD sample improved reliability (.68 to .76), but lengthening provided no useful improvement for either sample. The MCI change scores had low reliability, even with reweighting and adding additional subtests. The ADAS-Cog scores had low reliability for measuring change. Researchers using the ADAS-Cog should estimate and report reliability for their use of the change scores. The ADAS-Cog change scores are not recommended for assessment of meaningful clinical change.

    Histone acetylation is an example of covalent modification of chromatin structure that has the potential to regulate gene expression. Gcn5 is a prototypical histone acetyltransferase that associates with the transcriptional coactivator Ada2. In Arabidopsis, two genes encode proteins that resemble yeast ADA2 and share approximately 45% amino acid sequence identity. We previously reported that plants harboring a T-DNA insertion in the ADA2b gene display a dwarf phenotype with developmental defects in several organs. Here we describe T-DNA insertion alleles in the ADA2a gene, which result in no dramatic growth or developmental phenotype. Both ADA2a and ADA2b are expressed in a variety of plant tissues; moreover, expression of ADA2a from a constitutive promoter fails to complement the ada2b-1 mutant phenotype, consistent with the hypothesis that the two proteins have distinct biochemical roles. To further probe the cellular roles of ADA2a and ADA2b, we studied the response of the transcriptional coactivator mutants to abiotic stress. Although ada2b seedlings display hypersensitivity to salt and abscisic acid and altered responses to low temperature stress, the responses of ada2a seedlings to abiotic stress generally parallel those of wildtype plants. Intriguingly, ada2a;ada2b double mutant plants display an intermediate, gcn5-like phenotype, suggesting that ADA2a and ADA2b each work independently with GCN5 to affect genome function in Arabidopsis.

  20. Remolding Diversified Objects in Ada95: Toward A-Object Pattern

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Ada provides full capacities of supporting object-orientation,but the diversified objects patterned in Ada are so intricate that Ada95's aim would be demolished. In order to complement the disfigurement that Ada does lack for a pr istine notion of class, this paper presents a remolded object pattern known as A -object, an Ada-based class description language A-ObjAda aiming at support f or A-object pattern and the related approach for key algorithms and implementation . In consequent, A-ObjAda hereby promotes Ada with highlighted object-orientati on , which not only effectively exploits the capacities in Ada95, but also rational ly hides befuddling concepts from Ada95.

    Full Text Available BACKGROUND: Tuberculosis is an important cause of morbidity and mortality in both adults and children, especially in developing countries. For prevention of childhood tuberculosis, BCG vaccination is advocated. Protection is attained 4 - 6 weeks after BCG vaccination a nd is mainly due to cell mediated immunity. After BCG vaccination almost 12 to 15% of neonates do not develop scar but have positive cell mediated immune response. ADA estimation is simple and inexpensive method to assess the cell mediated immunity. OBJECT IVE: To estimate serum ADA levels in children with and without BCG scar, after receiving BCG vaccination. MATERIAL AND METHODS: This prospective observational study was conducted at a tertiary care hospital for a period of 2 years. Babies in post natal ward and infants up to the age of 12 weeks attending well baby clinic for BCG vaccination were included in the study. Serum ADA lev els were estimated before BCG vaccination and 12 - 14 weeks after the vaccination. ADA levels were estimated by colorimetric method. Presence or absence of BCG scar was noted at 12 - 14 weeks of age. RESULTS: A total of 75 babies followed up, of which only 60 babies noted to have scar and in rest 15 babies there was no scar noticed. Twenty unvaccinated babies at 12 weeks of age were included as controls. The Mean ADA levels are significantly elevated after BCG vaccination (34 . 12 ± 3 . 28 U/L in comparison to le vels before vaccination (12 . 55± 2 . 64 U/L with p value 0. 06. CONCLUSION: After BCG vaccination, there is increase in serum ADA levels indicating adequ ate immunity. Increase in ADA levels in children without scar after BCG vaccination may indicate the probability of adequate immunity.

  3. Analysis of Generalization Ability for Different AdaBoost Variants Based on Classification and Regression Trees

    2015-01-01

    Full Text Available As a machine learning method, AdaBoost is widely applied to data classification and object detection because of its robustness and efficiency. AdaBoost constructs a global and optimal combination of weak classifiers based on a sample reweighting. It is known that this kind of combination improves the classification performance tremendously. As the popularity of AdaBoost increases, many variants have been proposed to improve the performance of AdaBoost. Then, a lot of comparison and review studies for AdaBoost variants have also been published. Some researchers compared different AdaBoost variants by experiments in their own fields, and others reviewed various AdaBoost variants by basically introducing these algorithms. However, there is a lack of mathematical analysis of the generalization abilities for different AdaBoost variants. In this paper, we analyze the generalization abilities of six AdaBoost variants in terms of classification margins. The six compared variants are Real AdaBoost, Gentle AdaBoost, Modest AdaBoost, Parameterized AdaBoost, Margin-pruning Boost, and Penalized AdaBoost. Finally, we use experiments to verify our analyses.

  4. An automated quality assessor for Ada object-oriented designs

    Science.gov (United States)

    Bailin, Sidney C.

    1988-01-01

    A tool for evaluating object-oriented designs (OODs) for Ada software is described. The tool assumes a design expressed as a hierarchy of object diagrams. A design of this type identifies the objects of a system, an interface to each object, and the usage relationships between objects. When such a design is implemented in Ada, objects become packages, interfaces become package specifications, and usage relationships become Ada `with' clauses and package references. An automated quality assessor has been developed that is based on flagging undesirable design constructs. For convenience, distinctions are made among three levels of severity: questionable, undesirable, and hazardous. A questionable construct is one that may well be appropriate. An undesirable construct is one that should be changed because it is potentially harmful to the reliability, maintainability, or reusability of the software. A hazardous construct is one that is undesirable and that introduces a high level of risk.

    2011-01-01

    The AdaBoost algorithm was designed to combine many "weak" hypotheses that perform slightly better than random guessing into a "strong" hypothesis that has very low error. We study the rate at which AdaBoost iteratively converges to the minimum of the "exponential loss." Unlike previous work, our proofs do not require a weak-learning assumption, nor do they require that minimizers of the exponential loss are finite. Our first result shows that at iteration $t$, the exponential loss of AdaBoost's computed parameter vector will be at most $\\epsilon$ more than that of any parameter vector of $\\ell_1$-norm bounded by $B$ in a number of rounds that is at most a polynomial in $B$ and $1/\\epsilon$. We also provide lower bounds showing that a polynomial dependence on these parameters is necessary. Our second result is that within $C/\\epsilon$ iterations, AdaBoost achieves a value of the exponential loss that is at most $\\epsilon$ more than the best possible value, where $C$ depends on the dataset. We show that this d...

    1994-01-01

    One area of research of the Information Sciences Division at NASA Ames Research Center is devoted to the analysis and enhancement of processors and advanced computer architectures, specifically in support of automation and robotic systems. To compare systems' abilities to efficiently process Lisp and Ada, scientists at Ames Research Center have developed a suite of non-parallel benchmarks called ELAPSE. The benchmark suite was designed to test a single computer's efficiency as well as alternate machine comparisons on Lisp, and/or Ada languages. ELAPSE tests the efficiency with which a machine can execute the various routines in each environment. The sample routines are based on numeric and symbolic manipulations and include two-dimensional fast Fourier transformations, Cholesky decomposition and substitution, Gaussian elimination, high-level data processing, and symbol-list references. Also included is a routine based on a Bayesian classification program sorting data into optimized groups. The ELAPSE benchmarks are available for any computer with a validated Ada compiler and/or Common Lisp system. Of the 18 routines that comprise ELAPSE, provided within this package are 14 developed or translated at Ames. The others are readily available through literature. The benchmark that requires the most memory is CHOLESKY.ADA. Under VAX/VMS, CHOLESKY.ADA requires 760K of main memory. ELAPSE is available on either two 5.25 inch 360K MS-DOS format diskettes (standard distribution) or a 9-track 1600 BPI ASCII CARD IMAGE format magnetic tape. The contents of the diskettes are compressed using the PKWARE archiving tools. The utility to unarchive the files, PKUNZIP.EXE, is included. The ELAPSE benchmarks were written in 1990. VAX and VMS are trademarks of Digital Equipment Corporation. MS-DOS is a registered trademark of Microsoft Corporation.

    Klumpp, A. R.

    1994-01-01

    This package extends the Ada programming language to include linear algebra capabilities similar to those of the HAL/S programming language. The package is designed for avionics applications such as Space Station flight software. In addition to the HAL/S built-in functions, the package incorporates the quaternion functions used in the Shuttle and Galileo projects, and routines from LINPAK that solve systems of equations involving general square matrices. Language conventions in this package follow those of HAL/S to the maximum extent practical and minimize the effort required for writing new avionics software and translating existent software into Ada. Valid numeric types in this package include scalar, vector, matrix, and quaternion declarations. (Quaternions are fourcomponent vectors used in representing motion between two coordinate frames). Single precision and double precision floating point arithmetic is available in addition to the standard double precision integer manipulation. Infix operators are used instead of function calls to define dot products, cross products, quaternion products, and mixed scalar-vector, scalar-matrix, and vector-matrix products. The package contains two generic programs: one for floating point, and one for integer. The actual component type is passed as a formal parameter to the generic linear algebra package. The procedures for solving systems of linear equations defined by general matrices include GEFA, GECO, GESL, and GIDI. The HAL/S functions include ABVAL, UNIT, TRACE, DET, INVERSE, TRANSPOSE, GET, PUT, FETCH, PLACE, and IDENTITY. This package is written in Ada (Version 1.2) for batch execution and is machine independent. The linear algebra software depends on nothing outside the Ada language except for a call to a square root function for floating point scalars (such as SQRT in the DEC VAX MATHLIB library). This program was developed in 1989, and is a copyrighted work with all copyright vested in NASA.

  2. Overfitting Reduction of Text Classification Based on AdaBELM

    2017-07-01

    Full Text Available Overfitting is an important problem in machine learning. Several algorithms, such as the extreme learning machine (ELM, suffer from this issue when facing high-dimensional sparse data, e.g., in text classification. One common issue is that the extent of overfitting is not well quantified. In this paper, we propose a quantitative measure of overfitting referred to as the rate of overfitting (RO and a novel model, named AdaBELM, to reduce the overfitting. With RO, the overfitting problem can be quantitatively measured and identified. The newly proposed model can achieve high performance on multi-class text classification. To evaluate the generalizability of the new model, we designed experiments based on three datasets, i.e., the 20 Newsgroups, Reuters-21578, and BioMed corpora, which represent balanced, unbalanced, and real application data, respectively. Experiment results demonstrate that AdaBELM can reduce overfitting and outperform classical ELM, decision tree, random forests, and AdaBoost on all three text-classification datasets; for example, it can achieve 62.2% higher accuracy than ELM. Therefore, the proposed model has a good generalizability.

  3. Software tools to aid Pascal and Ada program design

    Energy Technology Data Exchange (ETDEWEB)

    Jankowitz, H.T.

    1987-01-01

    This thesis describes a software tool which analyses the style and structure of Pascal and Ada programs by ensuring that some minimum design requirements are fulfilled. The tool is used in much the same way as a compiler is used to teach students the syntax of a language, only in this case issues related to the design and structure of the program are of paramount importance. The tool operates by analyzing the design and structure of a syntactically correct program, automatically generating a report detailing changes that need to be made in order to ensure that the program is structurally sound. The author discusses how the model gradually evolved from a plagiarism detection system which extracted several measurable characteristics in a program to a model that analyzed the style of Pascal programs. In order to incorporate more-sophistical concepts like data abstraction, information hiding and data protection, this model was then extended to analyze the composition of Ada programs. The Ada model takes full advantage of facilities offered in the language and by using this tool the standard and quality of written programs is raised whilst the fundamental principles of program design are grasped through a process of self-tuition.

    2007-01-01

    Transmission Control Protocol (TCP) performance degrades in broadband geostationary satellite networks due to long propagation delays and high bit error rates. In this thesis, we propose TCP with algorithm modifications for adaptive delay and loss response (TCP-ADaLR) to improve TCP performance. TCP-ADaLR incorporates delayed acknowledgement mechanism recommended for Internet hosts. We evaluate and compare the performance of TCP-ADaLR, TCP SACK, and TCP NewReno, with and without delayed ackno...

    Gene therapy is a promising treatment option for monogenic diseases, but success has been seen in only a handful of studies thus far. We now document successful reconstitution of immune function in a child with the adenosine deaminase (ADA)-deficient form of severe combined immunodeficiency (SCID) following hematopoietic stem cell (HSC) gene therapy. An ADA-SCID child who showed a poor response to PEG-ADA enzyme replacement was enrolled into the clinical study. Following cessation of enzyme replacement therapy, autologous CD34(+) HSCs were transduced with an ADA-expressing gammaretroviral vector. Gene-modified cells were reinfused following one dose of preconditioning chemotherapy. Two years after the procedure, immunological and biochemical correction has been maintained with progressive increase in lymphocyte numbers, reinitiation of thymopoiesis, and systemic detoxification of ADA metabolites. Sustained vector marking with detection of polyclonal vector integration sites in multiple cell lineages and detection of ADA activity in red blood cells suggests transduction of early hematopoietic progenitors. No serious side effects were seen either as a result of the conditioning procedure or due to retroviral insertion. Gene therapy is an effective treatment option for the treatment of ADA-SCID.

    We have established the critical role of ADA3 as a coactivator of estrogen receptor (ER), as well as its role in cell cycle progression. Furthermore, we showed that ADA3 is predominantly nuclear in mammary epithelium, and in ER+, but is cytoplasmic in ER- breast cancers, the latter correlating with poor survival. However, the role of nuclear ADA3 in human mammary epithelial cells (hMECs), and in ER+ breast cancer cells, as well as the importance of ADA3 expression in relation to patient prognosis and survival in ER+ breast cancer have remained uncharacterized. We overexpressed ADA3 in hMECs or in ER+ breast cancer cells and assessed the effect on cell proliferation. The expression of ADA3 was analyzed then correlated with the expression of various prognostic markers, as well as survival of breast cancer patients. Overexpression of ADA3 in ER- hMECs as well as in ER+ breast cancer cell lines enhanced cell proliferation. These cells showed increased cyclin B and c-MYC, decreased p27 and increased SKP2 levels. This was accompanied by increased mRNA levels of early response genes c-FOS, EGR1, and c-MYC. Analysis of breast cancer tissue specimens showed a significant correlation of ADA3 nuclear expression with c-MYC expression. Furthermore, nuclear ADA3 and c-MYC expression together showed significant correlation with tumor grade, mitosis, pleomorphism, NPI, ER/PR status, Ki67 and p27 expression. Importantly, within ER+ cases, expression of nuclear ADA3 and c-MYC also significantly correlated with Ki67 and p27 expression. Univariate Kaplan Meier analysis of four groups in the whole, as well as the ER+ patients showed that c-MYC and ADA3 combinatorial phenotypes showed significantly different breast cancer specific survival with c-MYC-high and ADA3-Low subgroup had the worst outcome. Using multivariate analyses within the whole cohort and the ER+ subgroups, the significant association of ADA3 and c-MYC expression with patients' outcome was independent of tumor grade

    Full Text Available Plotino é conhecido pela doutrina das três hipóstases: o Uno, a Inteligência e a Alma. Enquanto neoplatônico, sua doutrina é pensada a partir da visão platônica do mundo. Todavia, na terceira Enéada o filósofo se põe a discutir longamente a concepção antiga do tempo, fortemente devedora da doutrina aristotélica. Plotino, ao seu modo, consegue reinterpretar e adequar a noção aristotélica do tempo à concepção de mundo platônica. O tempo, para Plotino, por um lado, permanece referido ao movimento, concordando com Aristóteles, e por outro, é imagem de uma outra forma mais perfeira, a eternidade, concordando com a divisão do mundo em sensivel e supra-sensível de Platão. Por conseguir compreender o tempo a partir desses dois registros, o platônico e o aristotélico, Plotino figura como um ponto importante para se compreender as teorias do tempo que vieram depois dele, principalmente a de Santo Agostinho. Nosso ensaio pretende discutir a noção de tempo em Plotino, a partir da terceira Enéada, a fim de fornecer instrumentos para tal compreensão.

  15. Autoimmune dysregulation and purine metabolism in adenosine deaminase (ADA-deficiency

    2012-08-01

    Full Text Available Genetic defects in the adenosine deaminase (ADA gene are among the most common causes for severe combined immunodeficiency (SCID. ADA-SCID patients suffer from lymphopenia, severely impaired cellular and humoral immunity, failure to thrive and recurrent infections. Currently available therapeutic options for this otherwise fatal disorder include bone marrow transplantation (BMT, enzyme replacement therapy with bovine ADA (PEG-ADA or hematopoietic stem cell gene therapy (HSC-GT. Although varying degrees of immune reconstitution can be achieved by these treatments, breakdown of tolerance is a major concern in ADA-SCID. Immune dysregulation such as autoimmune hypothyroidism, diabetes mellitus, hemolytic anemia, and immune thrombocytopenia are frequently observed in milder forms of the disease. However, several reports document similar complications also in patients on long-term PEG-ADA and after BMT or GT treatment.A skewed repertoire and decreased immune functions have been implicated in autoimmunity observed in certain B-cell and/or T-cell immunodeficiencies, but it remains unclear to what extent specific mechanisms of tolerance are affected in ADA deficiency. Herein we provide an overview about ADA-SCID and the autoimmune manifestations reported in these patients before and after treatment. We also assess the value of the ADA-deficient mouse model as a useful tool to study both immune and metabolic disease mechanisms. With focus on regulatory T and B cells we discuss the lymphocyte subpopulations particularly prone to contribute to the loss of self-tolerance and onset of autoimmunity in ADA deficiency. Moreover we address which aspects of immune dysregulation are specifically related to alterations in purine metabolism caused by the lack of ADA and the subsequent accumulation of metabolites with immunomodulatory properties.

    Adenosin deaminase (ADA) deficiency is the cause for Severe Combined Immunodeficiency (SCID) in about 15% of patients with SCID, often presenting as T (-)B (-)NK (-)SCID. Treatment options for ADA-SCID are enzyme replacement, bone marrow transplantation or gene therapy. We here describe the first patient with ADA-SCID and fatal hepatic failure despite bone marrow transplantation from a 10/10 HLA identical related donor. As patients with ADA-SCID may be at yet underestimated increased risk for rapid hepatic failure we speculate whether hepatitis in ADA-SCID should lead to the immediate treatment with enzyme replacement by pegylated ADA.

    Adenosine deaminase deficiency fosters a rare, devastating pediatric immune deficiency with concomitant opportunistic infections, metabolic anomalies and multiple organ system pathology. The standard of care for adenosine deaminase deficient severe combined immune deficiency (ADA-SCID) includes enzyme replacement therapy or bone marrow transplantation. Gene therapies for ADA-SCID over nearly two decades have exclusively involved retroviral vectors targeted to lymphocytes and hematopoetic progenitors. These groundbreaking gene therapies represent a revolution in clinical medicine, but come with several challenges, including the risk of insertional mutagenesis. An alternative gene therapy for ADA-SCID may utilize recombinant adeno-associated virus vectors in vivo, with numerous target tissues, to foster ectopic expression and secretion of adenosine deaminase. This review endeavors to describe ADA-SCID, the traditional treatments, previous retroviral gene therapies, and primarily, alternative recombinant adeno-associated virus-based strategies to remedy this potentially fatal genetic disease.

    2007-05-01

    Inherited adenosine deaminase (ADA) deficiency is a rare metabolic disorder that causes immunodeficiency, varying from severe combined immunodeficiency (SCID) in the majority of cases to a less severe form in a small minority of patients. Five patients of Somali origin from four unrelated families, with severe ADA-SCID, were registered in the Greater London area. Patients and their parents were investigated for the nonsense mutation Q3X (ADA c7C>T), two missense mutations K80R (ADA c239A>G) and R142Q (ADA c425G>A), and a TAAA repeat located at the 3' end of an Alu element (AluVpA) positioned 1.1 kb upstream of the ADA transcription start site. All patients were homozygous for the haplotype ADA-7T/ADA-239G/ADA-425G/AluVpA7. Among 207 Somali immigrants to Denmark, the frequency of ADA c7C>T and the maximum likelihood estimate of the frequency of the haplotype ADA-7T/ADA-239G/ADA-425G/AluVpA7 were both 0.012 (carrier frequency 2.4%). Based on the analysis of AluVpA alleles, the ADA c7C/T mutation was estimated to be approximately 7,100 years old. Approximately 1 out of 5 - 10000 Somali children will be born with ADA deficiency due to an ADA c7C/T mutation, although within certain clans the frequency may be significantly higher. ADA-SCID may be a frequent immunodeficiency disorder in Somalia, but will be underdiagnosed due to the prevailing socioeconomic and nutritional deprivation.

    Construction of the National Ignition Facility laser at Lawrence Livermore National Laboratory features a distributed control system that uses object-oriented software engineering techniques. Control of 60,000 devices is effected using a network of some 500 computers. The software is being written in Ada and communicates through CORBA. Software controls are implemented in two layers: individual device controllers and a supervisory layer. The software architecture provides services in the form of frameworks that address issues common to event-driven control systems. Those services are allocated to levels that strictly prescribe their interdependency so the levels are separately reusable. The project has completed its final design review. The delivery of the first increment takes place in October 1998. Keywords Distributed control system, object-oriented development, CORBA, application frameworks, levels of abstraction

    Reynolds, P. F.; Knight, J. C.; Urquhart, J. I. A.

    1983-01-01

    The issues involved in the use of the programming language Ada on distributed systems are discussed. The effects of Ada programs on hardware failures such as loss of a processor are emphasized. It is shown that many Ada language elements are not well suited to this environment. Processor failure can easily lead to difficulties on those processors which remain. As an example, the calling task in a rendezvous may be suspended forever if the processor executing the serving task fails. A mechanism for detecting failure is proposed and changes to the Ada run time support system are suggested which avoid most of the difficulties. Ada program structures are defined which allow programs to reconfigure and continue to provide service following processor failure.

    2016-01-01

    Adenosine is an important regulator of the immune response and adenosine deaminase (ADA) inhibits this regulatory effect by converting adenosine into functionally inactive molecules. Studies have shown that adenosine receptor (AR) agonists can be either anti- or pro-inflammatory. Clarification of the mechanisms that cause these opposing effects should provide a better guide for therapeutic intervention. In this study, we investigated the effect of ADA on the development of experimental autoimmune uveitis (EAU) induced by immunizing EAU-prone mice with a known uveitogenic peptide, IRBP1–20. Our results showed that the effective time to administer a single dose of ADA to suppress induction of EAU was 8–14 days post-immunization, shortly before EAU expression, but ADA treatment at other time points exacerbated disease. ADA preferentially inhibited Th17 responses and this effect was γδ T cell-dependent. Our results demonstrated that the existing immune status strongly influences the anti- or proinflammatory effects of ADA. Our observations should help improve the design of ADA- and AR-targeted therapies. PMID:26856700

Compared with Gabor wavelet features,QWT features are superior both in accuracy and computation complexity.

    The use of the Ada language and design methodologies that utilize its features has a strong impact on all phases of the software development project lifecycle. At the National Aeronautics and Space Administration/Goddard Space Flight Center (NASA/GSFC), the Software Engineering Laboratory (SEL) conducted an experiment in parallel development of two flight dynamics systems in FORTRAN and Ada. The teams found some qualitative differences between the system test phases of the two projects. Although planning for system testing and conducting of tests were not generally affected by the use of Ada, the solving of problems found in system testing was generally facilitated by Ada constructs and design methodology. Most problems found in system testing were not due to difficulty with the language or methodology but to lack of experience with the application.

    Adenosine is an important regulator of the immune response and adenosine deaminase (ADA) inhibits this regulatory effect by converting adenosine into functionally inactive molecules. Studies have shown that adenosine receptor (AR) agonists can be either anti- or pro-inflammatory. Clarification of the mechanisms that cause these opposing effects should provide a better guide for therapeutic intervention. In this study, we investigated the effect of ADA on the development of experimental autoim...

    Despite the availability of several large-scale proteomics studies aiming to identify protein interactions on a global scale, little is known about how proteins interact and are organized within macromolecular complexes. Here, we describe a technique that consists of a combination of biochemistry approaches, quantitative proteomics and computational methods using wild-type and deletion strains to investigate the organization of proteins within macromolecular protein complexes. We applied this technique to determine the organization of two well-studied complexes, Spt-Ada-Gcn5 histone acetyltransferase (SAGA) and ADA, for which no comprehensive high-resolution structures exist. This approach revealed that SAGA/ADA is composed of five distinct functional modules, which can persist separately. Furthermore, we identified a novel subunit of the ADA complex, termed Ahc2, and characterized Sgf29 as an ADA family protein present in all Gcn5 histone acetyltransferase complexes. Finally, we propose a model for the architecture of the SAGA and ADA complexes, which predicts novel functional associations within the SAGA complex and provides mechanistic insights into phenotypical observations in SAGA mutants.

  11. Constructing a working taxonomy of functional Ada software components for real-time embedded system applications

    A major impediment to a systematic attack on Ada software reusability is the lack of an effective taxonomy for software component functions. The scope of all possible applications of Ada software is considered too great to allow the practical development of a working taxonomy. Instead, for the purposes herein, the scope of Ada software application is limited to device and subsystem control in real-time embedded systems. A functional approach is taken in constructing the taxonomy tree for identified Ada domain. The use of modular software functions as a starting point fits well with the object oriented programming philosophy of Ada. Examples of the types of functions represented within the working taxonomy are real time kernels, interrupt service routines, synchronization and message passing, data conversion, digital filtering and signal conditioning, and device control. The constructed taxonomy is proposed as a framework from which a need analysis can be performed to reveal voids in current Ada real-time embedded programming efforts for Space Station.

    Platelet aggregation and adenosine deaminase (ADA) activity were evaluated in pregnant women living with some disease conditions including hypertension, diabetes mellitus and human immunodeficiency virus infection. The subject population is consisted of 15 non-pregnant healthy women [control group (CG)], 15 women with normal pregnancy (NP), 7 women with hypertensive pregnancy (HP), 10 women with gestational diabetes mellitus (GDM) and 12 women with human immunodeficiency virus-infected pregnancy (HIP) groups. The aggregation of platelets was checked using an optical aggregometer, and serum ADA activity was determined using the colorimetric method. After the addition of 5 µM of agonist adenosine diphosphate, the percentage of platelet aggregation was significantly (p < 0·05) increased in NP, HP, GDM and HIP groups when compared with the CG, while the addition of 10 µM of the same agonist caused significant (p < 0·05) elevations in HP, GDM and HIP groups when compared with CG. Furthermore, ADA activity was significantly (p < 0·05) enhanced in NP, HP, GDM and HIP groups when compared with CG. In this study, the increased platelet aggregation and ADA activity in pregnancy and pregnancy-associated diseases suggest that platelet aggregation and ADA activity could serve as peripheral markers for the development of effective therapy in the maintenance of homeostasis and some inflammatory process in these pathophysiological conditions.

    Adult human subcutaneous adipose tissue contains cells with intriguing multilineage developmental plasticity, much like marrow-derived mesenchymal stem cells. Putative stem or progenitor cells from fat have been given many different names in the literature, reflecting an early and evolving consensus regarding their phenotypic characterization. The study reported here used microarrays to evaluate over 170 genes relating to angiogenesis and extracellular matrix in undifferentiated, early-passage human adipose-derived adherent stromal (hADAS) cells isolated from three separate donors. The hADAS populations unanimously transcribed 66% of the screened genes, and 83% were transcribed by at least two of the three populations. The most highly transcribed genes relate to functional groupings such as cell adhesion, matrix proteins, growth factors and receptors, and proteases. The transcriptome of hADAS cells demonstrated by this work reveals many similarities to published profiles of bone marrow mesenchymal stem cells (MSCs). In addition, flow analysis of over 24 hADAS cell surface proteins (n = 7 donors) both confirms and expands on the existing literature and reveals strong intergroup correlation, despite an inconsistent nomenclature and the lack of standardized protocols for cell isolation and culture. Finally, based on flow analysis and reverse transcription polymerase chain reaction studies, our results suggest that hADAS cells do not express several proteins that are implicated as markers of "stemness" in other stem cell populations, including telomerase, CD133, and the membrane transporter ABCG2.

    Severe combined immunodeficiency due to adenosine-deaminase defect (ADA-SCID) is usually deadly in childhood because of severe recurrent infections. When clinical diagnosis is done, permanent damages due to infections or metabolite accumulation are often present. Gene therapy, bone marrow transplantation or enzyme replacement therapy may be effective if started early. The aim of this study was to set-up a robust method suitable for screening with a minimized preparation process and with inexpensive running costs, for diagnosing ADA-SCID by tandem mass spectrometry. ADA-SCID satisfies all the criteria for inclusion in a newborn screening program. We describe a protocol revised to incorporate adenosine and 2-deoxyadenosine testing into an expanded newborn screening program. We assessed the effectiveness of this approach testing dried blood spots from 4 genetically confirmed early-onset and 5 delayed-onset ADA-SCID patients. Reference values were established on 50,000 healthy newborns (deoxyadenosine <0.09μmol/L, adenosine <1.61μmol/L). We also developed a second tier test to distinguish true positives from false positives and improve the positive predictive value of an initial abnormal result. In the first 18 months, the pilot project has identified a newborn with a genetically confirmed defect in adenosine deaminase (ADA) gene. The results show that the method having great simplicity, low cost and low process preparations can be fully applicable to a mass screening program.

A lack of the enzyme ADA allows accumulation of toxic metabolites causing defects of both cell mediated and humoral immunity leading to ADA severe combined immune deficiency (SCID, a condition that can be fatal in early infancy if left untreated. Hematopoietic stem cell transplant is curative but is dependent on a good donor match. Other therapeutic options include enzyme replacement therapy (ERT with pegademase bovine (PEG-ADA and more recently gene therapy. PEG-ADA has been used in over 150 patients worldwide and has allowed stabilization of patients awaiting more definitive treatment with hematopoietic stem cell transplant. It affords both metabolic detoxification and protective immune function with patients remaining clinically well, but immune reconstitution is often suboptimal and may not be long lived. We discuss the pharmacokinetics, immune reconstitution, effects on systemic disease and side effects of treatment with PEG-ADA. We also review the long-term outcome of patients receiving ERT and discuss the role of PEG-ADA in the management of infants and children with ADA-SCID, alongside other therapeutic options.Keywords: adenosine deaminase deficiency, PEG-ADA, enzyme replacement therapy, severe combined immune deficiency (SCID

    针对AdaBoost集成时难分样本权重扩张导致训练样本在更新时分布失衡的问题,提出一种基于正负类样本损失函数(LF)的权重更新策略.权重的调整不仅与训练误差有关,还考虑到基分类器对不同类别样本的正确分类能力,从而避免训练样本过度集中于某一类的异常现象.实验结果表明,基于LF的AdaBoost能在提高收敛性能的情况下,提高算法精度,克服样本分布失衡问题.偏差方差分析的结果显示,该算法在改善偏差的情况下,能有效地减小错误率中的方差成分,提高集成的泛化能力.%As to the issue that the weight expansion for hardest samples can cause imbalance when updating the training sample in AdaBoost algorithm, an improved approach based on the Loss Function (LF) of the different patterns, namely, LF-AdaBoost, was proposed. The weight tuning was affected not only by the training error, but the performance of base classifiers for different classes, thus avoiding the excessive concentration phenomenon. The results based on UCI data sets and different base classifiers have shown that the approach can improve the speed of convergence and overcome the imbalance,as well as promote the generalization ability of ensemble classifier.

    Plant growth and crop production can be greatly affected by common environmental stresses such as drought, high salinity and low temperatures. Gene expression is affected by several abiotic stresses. Stress-inducible genes are regulated by transcription factors and epigenetic mechanisms such as histone modifications. In this Mini-Review, we have explored the role of transcriptional adaptor ADA2b in Arabidopsis responses to abiotic stress. ADA2b is required for the expression of genes involved in abiotic stress either by controlling H3 and H4 acetylation in the case of salt stress or affecting nucleosome occupancy in low temperatures response.

    To conduct a psychometric analysis to determine the adequacy of instruments that measure cognition in Alzheimer's disease trials. Both the Alzheimer's Disease Assessment Scale - Cognition (ADAS-Cog) and the Neuropsychological Test Battery (NTB) are validated outcome measures for clinical trials in Alzheimer's disease and are approved also for regulatory purposes. However, it is not clear how comparable they are in measuring cognitive function. In fact, many recent trials in Alzheimer's disease patients have failed and it has been questioned if ADAS-Cog still is a sensitive measure. The present paper examines the psychometric properties of ADAS-Cog and NTB, based on a post hoc analysis of data from a clinical trial (NCT01024660), which was conducted by AstraZeneca, in mild-to-moderate Alzheimer's disease (AD) patients, with a Mini Mental State Examination (MMSE) Total score 16-24. Acceptability, reliability, different types of validity and ability to detect change were assessed using relevant statistical methods. Total scores of both tests, as well as separate domains of both tests, including the Wechsler Memory Scale (WMS), Rey Auditory Verbal Learning Test (RAVLT) and Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency Condition, were analyzed. Overall, NTB performed well, with acceptable reliability and ability to detect change, while ADAS-Cog had insufficient psychometric properties, including ceiling effects in 8 out of a total of 11 ADAS-Cog items in mild AD patients, as well as low test-retest reliability in some of the items. Based on a direct comparison on the same patient sample, we see advantages of the NTB compared with the ADAS-Cog for the evaluation of cognitive function in the population of mild-to-moderate AD patients. The results suggest that not all of ADAS-Cog items are relevant for both mild and moderate AD population. This validation study demonstrates satisfactory psychometric properties of the NTB, while ADAS-Cog was found to be

    Adenosine Deaminase (ADA) deficiency is an autosomal recessive variant of severe combined immunodeficiency (SCID) caused by systemic accumulation of ADA substrates. Neurological and behavioral abnormalities observed in ADA-SCID patients surviving after stem cell transplantation or gene therapy represent an unresolved enigma in the field. We found significant neurological and cognitive alterations in untreated ADA-SCID patients as well as in two groups of patients after short- and long-term enzyme replacement therapy with PEG-ADA. These included motor dysfunction, EEG alterations, sensorineural hypoacusia, white matter and ventricular alterations in MRI as well as a low mental development index or IQ. Ada-deficient mice were significantly less active and showed anxiety-like behavior. Molecular and metabolic analyses showed that this phenotype coincides with metabolic alterations and aberrant adenosine receptor signaling. PEG-ADA treatment corrected metabolic adenosine-based alterations, but not cellular and signaling defects, indicating an intrinsic nature of the neurological and behavioral phenotype in ADA deficiency.

    2017-02-14

    Adenosine deaminase-deficient severe combined immune deficiency (ADA SCID) accounts for 10-15% of cases of human SCID. From what was once a uniformly fatal disease, the prognosis for infants with ADA SCID has improved greatly based on the development of multiple therapeutic options, coupled with more frequent early diagnosis due to implementation of newborn screening for SCID. We review the various treatment approaches for ADA SCID including allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen-matched sibling or family member or from a matched unrelated donor or a haplo-identical donor, autologous HSCT with gene correction of the hematopoietic stem cells (gene therapy-GT), and enzyme replacement therapy (ERT) with polyethylene glycol-conjugated adenosine deaminase. Based on growing evidence of safety and efficacy from GT, we propose a treatment algorithm for patients with ADA SCID that recommends HSCT from a matched family donor, when available, as a first choice, followed by GT as the next option, with allogeneic HSCT from an unrelated or haplo-identical donor or long-term ERT as other options.

  17. Homozygosity for a novel adenosine deaminase (ADA) nonsense mutation (Q3>X) in a child with severe combined immunodeficiency (SCID)

    1994-09-01

    A Somali girl was diagnosed with ADA-deficient SCID at 7 mo; she responded well to PEG-ADA replacement and is now 3.3 yr old. ADA mRNA was undetectable (Northern) in her cultured T cells, but was present in T cells of her parents and two sibs. All PCR-amplified exon 1 genomic clones from the patient had a C>T transition at bp 7 relative to the start of translation, replacing Gln at codon 3 (AGA) with a termination codon (TGA, Q3>X). Patient cDNA (prepared by RT-PCR with a 5{prime} primer that covered codons 1-7) had a previously described polymorphism, K80>R, but was otherwise normal, indicating that no other coding mutations were present. A predicted new genomic BfaI restriction site was used to establish her homozygosity for Q3>X and to analyze genotypes of family members. We also analyzed the segregation of a variable Alu polyA-associated TAAA repeat (AluVpA) situated 5{prime} of the ADA gene. Three different AluVpA alleles were found, one of which was only present in the father and was not associated with his Q3>X allele. Because the father`s RBCs had only {approximately}15% of normal ADA activity, we analyzed his ADA cDNA. We found a G>A transition at bp 425 that substitutes Gln for Arg142, a solvent-accessible residue, and eliminates a BsmAI site in exon 5. ADA activity of the R142>Q in vitro translation product was 20-25% of wild type ADA translation product, suggesting that R142>Q is a new {open_quote}partial{close_quote} ADA deficiency mutation. As expected, Q3>X mRNA did not yield a detectable in vitro translation product. We conclude that the patient`s father is a compound heterozygote carrying the ADA Q3>X/R142>Q genotype. {open_quote}Partial{close_quote} ADA deficiency unassociated with immunodeficiency is relatively common in individuals of African descent. The present findings and previous observations suggest that {open_quote}partial{close_quote} ADA deficiency may have had an evolutionary advantage.

    The kinetic parameters of adenosine deaminase such as Km and Ki were determined in the absence and presence of adenine derivatives (R1-R24) in sodium phosphate buffer (50 mM; pH 7.5) solution at 27 degrees C. These kinetic parameters were used for QSAR analysis. As such, we found some theoretical descriptors to which the binding affinity of adenosine deaminase (ADA) towards several adenine nucleosides as inhibitors is correlated. QSAR analysis has revealed that binding affinity of the adenine nucleosides upon interaction with ADA depends on the molecular volume, dipole moment of the molecule, electric charge around the N1 atom, and the highest of positive charge for the related molecules.

  1. Discrimination of Breast Tumors in Ultrasonic Images by Classifier Ensemble Trained with AdaBoost

    Takemura, Atsushi; Shimizu, Akinobu; Hamamoto, Kazuhiko

    In this paper, we propose a novel method for acurate automated discrimination of breast tumors (carcinoma, fibroadenoma, and cyst). We defined 199 features related to diagnositic observations noticed when a doctor judges breast tumors, such as internal echo, shape, and boundary echo. These features included novel features based on a parameter of log-compressed K distribution, which reflect physical characteristics of ultrasonic B-mode imaging. Furthermore, we propose a discrimination method of breast tumors by using an ensemble classifier based on the multi-class AdaBoost algorithm with effective features selection. Verification by analyzing 200 carcinomas, 30 fibroadenomas and 30 cycts showed the usefulness of the newly defined features and the effectiveness of the discrimination by using an ensemble classifier trained by AdaBoost.

  3. Translating an AI application from Lisp to Ada: A case study

    Davis, Gloria J.

    1991-01-01

    A set of benchmarks was developed to test the performance of a newly designed computer executing both Lisp and Ada. Among these was AutoClassII -- a large Artificial Intelligence (AI) application written in Common Lisp. The extraction of a representative subset of this complex application was aided by a Lisp Code Analyzer (LCA). The LCA enabled rapid analysis of the code, putting it in a concise and functionally readable form. An equivalent benchmark was created in Ada through manual translation of the Lisp version. A comparison of the execution results of both programs across a variety of compiler-machine combinations indicate that line-by-line translation coupled with analysis of the initial code can produce relatively efficient and reusable target code.

  4. Languages for artificial intelligence: Implementing a scheduler in LISP and in Ada

    Hays, Dan

    1988-01-01

    A prototype scheduler for space experiments originally programmed in a dialect of LISP using some of the more traditional techniques of that language, was recast using an object-oriented LISP, Common LISP with Flavors on the Symbolics. This object-structured version was in turn partially implemented in Ada. The Flavors version showed a decided improvement in both speed of execution and readability of code. The recasting into Ada involved various practical problems of implementation as well as certain challenges of reconceptualization in going from one language to the other. Advantages were realized, however, in greater clarity of the code, especially where more standard flow of control was used. This exercise raised issues about the influence of programming language on the design of flexible and sensitive programs such as schedule planners, and called attention to the importance of factors external to the languages themselves such as system embeddedness, hardware context, and programmer practice.

  10. Reinforced AdaBoost learning for object detection with local pattern representations.

    Science.gov (United States)

    Lee, Younghyun; Han, David K; Ko, Hanseok

    2013-01-01

    A reinforced AdaBoost learning algorithm is proposed for object detection with local pattern representations. In implementing AdaBoost learning, the proposed algorithm employs an exponential criterion as a cost function and Newton's method for its optimization. In particular, we introduce an optimal selection of weak classifiers minimizing the cost function and derive the reinforced predictions based on a judicial confidence estimate to determine the classification results. The weak classifier of the proposed method produces real-valued predictions while that of the conventional AdaBoost method produces integer valued predictions of +1 or -1. Hence, in the conventional learning algorithms, the entire sample weights are updated by the same rate. On the contrary, the proposed learning algorithm allows the sample weights to be updated individually depending on the confidence level of each weak classifier prediction, thereby reducing the number of weak classifier iterations for convergence. Experimental classification performance on human face and license plate images confirm that the proposed method requires smaller number of weak classifiers than the conventional learning algorithm, resulting in higher learning and faster classification rates. An object detector implemented based on the proposed learning algorithm yields better performance in field tests in terms of higher detection rate with lower false positives than that of the conventional learning algorithm.

  11. Software engineering and Ada (Trademark) training: An implementation model for NASA

    Science.gov (United States)

    Legrand, Sue; Freedman, Glenn

    1988-01-01

    The choice of Ada for software engineering for projects such as the Space Station has resulted in government and industrial groups considering training programs that help workers become familiar with both a software culture and the intricacies of a new computer language. The questions of how much time it takes to learn software engineering with Ada, how much an organization should invest in such training, and how the training should be structured are considered. Software engineering is an emerging, dynamic discipline. It is defined by the author as the establishment and application of sound engineering environments, tools, methods, models, principles, and concepts combined with appropriate standards, guidelines, and practices to support computing which is correct, modifiable, reliable and safe, efficient, and understandable throughout the life cycle of the application. Neither the training programs needed, nor the content of such programs, have been well established. This study addresses the requirements for training for NASA personnel and recommends an implementation plan. A curriculum and a means of delivery are recommended. It is further suggested that a knowledgeable programmer may be able to learn Ada in 5 days, but that it takes 6 to 9 months to evolve into a software engineer who uses the language correctly and effectively. The curriculum and implementation plan can be adapted for each NASA Center according to the needs dictated by each project.

  12. Using Ada to implement the operations management system in a community of experts

    Frank, M. S.

    1986-01-01

    An architecture is described for the Space Station Operations Management System (OMS), consisting of a distributed expert system framework implemented in Ada. The motivation for such a scheme is based on the desire to integrate the very diverse elements of the OMS while taking maximum advantage of knowledge based systems technology. Part of the foundation of an Ada based distributed expert system was accomplished in the form of a proof of concept prototype for the KNOMES project (Knowledge-based Maintenance Expert System). This prototype successfully used concurrently active experts to accomplish monitoring and diagnosis for the Remote Manipulator System. The basic concept of this software architecture is named ACTORS for Ada Cognitive Task ORganization Scheme. It is when one considers the overall problem of integrating all of the OMS elements into a cooperative system that the AI solution stands out. By utilizing a distributed knowledge based system as the framework for OMS, it is possible to integrate those components which need to share information in an intelligent manner.

    Full Text Available Objective. This study aimed to investigate the presence and activity of the ecto adenosine deaminase (E-ADA enzyme in tachyzoites of Neospora caninum (Nc-1 strain, as well as to assess the activity of a well-known E-ADA inhibitor, the deoxycoformycin. Materials and methods. The parasites were grown in cell culture, being subsequently separated in a pellet of tachyzoites, on which the E-ADA activity was tested using the concentrations 0 (control, 0.2, 0.4 and 0.8 mg mL-1. Results. The E-ADA showed high activity, progressively increasing its activity according to the enhancement of the protein concentration. The test was carried out with different concentrations of deoxycoformycin, showing that it was able to inhibit the E-ADA present on the free form of the parasite. Conclusions. Based on these results we conclude that the E-ADA is present on tachyzoites of N. caninum, and deoxycoformycin is able to inhibit this enzyme. In this sense, knowing the negative impact of N. caninum on reproductive issue in cattle (mainly abortion, might it is an alternative in order to deal with this parasitic infection.

    The plant seed is a leading platform amongst plant-based storage systems for the production of recombinant proteins. In this study, we compared the activity of human adenosine deaminase (hADA) expressed in transgenic seeds of three different plant species: pea (Pisum sativum L.), Nicotiana benthamiana L. and tarwi (Lupinus mutabilis Sweet). All three species were transformed with the same expression vector containing the hADA gene driven by the seed-specific promoter LegA2 with an apoplast targeting pinII signal peptide. During the study, several independent transgenic lines were generated and screened from each plant species and only lines with a single copy of the gene of interest were used for hADA expression analysis. A stable transgenic canola line expressing the ADA protein, under the control of 35S constitutive promoter was used as both as a positive control and for comparative study with the seed specific promoter. Significant differences were detected in the expression of hADA. The highest activity of the hADA enzyme (Units/g seed) was reported in tarwi (4.26 U/g) followed by pea (3.23 U/g) and Nicotiana benthamiana (1.69 U/g). The expression of mouse ADA in canola was very low in both seed and leaf tissue compared to other host plants, confirming higher activity of seed specific promoter. Altogether, these results suggest that tarwi could be an excellent candidate for the production of valuable recombinant proteins.

    2015-01-01

    An advanced driver assistance system (ADAS) provided information about speed limits, speed, speeding, and following distance. Information was presented to the participants by means of a head-up display. Effects of the information on speed and headway control were studied in a longer-term driving simulator study including 12 repeated measures spread out over 4 weeks. Nine healthy older drivers between the ages of 65 and 82 years and 9 drivers between the ages of 68 and 82 years diagnosed with Parkinson's disease (PD) participated in the study. Within the 4 weeks, groups completed 12 consecutive sessions (10 with ADAS and 2 without ADAS) in a driving simulator. Results indicate an effect of ADAS use on performance. Removing ADAS after short-term exposure led to deterioration of performance in all speed measures in the group of drivers diagnosed with PD. These results suggest that provision of traffic information was utilized by drivers diagnosed with PD in order to control their speed.

  8. Characterization of yeast histone H3-specific type B histone acetyltransferases identifies an ADA2-independent Gcn5p activity

    Directory of Open Access Journals (Sweden)

    Parthun Mark R

    2004-07-01

    Full Text Available Abstract Background The acetylation of the core histone NH2-terminal tails is catalyzed by histone acetyltransferases. Histone acetyltransferases can be classified into two distinct groups (type A and B on the basis of cellular localization and substrate specificity. Type B histone acetyltransferases, originally defined as cytoplasmic enzymes that acetylate free histones, have been proposed to play a role in the assembly of chromatin through the acetylation of newly synthesized histones H3 and H4. To date, the only type B histone acetyltransferase activities identified are specific for histone H4. Results To better understand the role of histone acetylation in the assembly of chromatin structure, we have identified additional type B histone acetyltransferase activities specific for histone H3. One such activity, termed HatB3.1, acetylated histone H3 with a strong preference for free histones relative to chromatin substrates. Deletion of the GCN5 and ADA3 genes resulted in the loss of HatB3.1 activity while deletion of ADA2 had no effect. In addition, Gcn5p and Ada3p co-fractionated with partially purified HatB3.1 activity while Ada2p did not. Conclusions Yeast extracts contain several histone acetyltransferase activities that show a strong preference for free histone H3. One such activity, termed HatB3.1, appears to be a novel Gcn5p-containing complex which does not depend on the presence of Ada2p.

Core samples from the boreholes drilled for the construction of the bridge revealed a relatively complex subsurface geological structure. An Upper Cretaceous-Paleogene flysch formation and Middle Miocene Sarmatian sediments were found near the surface on the right bank of the Sava River. However, at the tip of Ada Ciganlija, the Upper Cretaceous-Palaeogene flysch strata were found below several different Miocene and Quaternary units. In the deepest borehole DB-6, the flysch deposits were found at a depth of 80 meters. On the left bank of the Sava River in New Belgrade, only Upper Miocene Pannonian marls and Pleistocene and Holocene alluvial deposits were drilled. Based on a comparative analysis of the borehole sections and structural characteristics of the rocks, it could be concluded that the Pre-Quaternary units cascade subsided along sub-parallel faults towards N-NW.

    The results of efforts to apply powerful Ada constructs to the formatted message handling process are described. The goal of these efforts was to extend the state-of-technology in message handling while at the same time producing production-quality, reusable code. The first effort was initiated in September, 1984 and delivered in April, 1985. That product, the Generic Message Handling Facility, met initial goals, was reused, and is available in the Ada Repository on ARPANET. However, it became apparent during its development that the initial approach to building a message handler template was not optimal. As a result of this initial effort, several alternate approaches were identified, and research is now on-going to identify an improved product. The ultimate goal is to be able to instantly build a message handling system for any message format given a specification of that message format. The problem lies in how to specify the message format, and one that is done, how to use that information to build the message handler. Message handling systems and message types are described. The initial efforts, its results and its shortcomings are detailed. The approach now being taken to build a system which will be significantly easier to implement, and once implemented, easier to use, is described. Finally, conclusions are offered.

    Full Text Available The Americans with Disabilities Act (ADA, 1990 is the cornerstone of civil rights policy for people with disabilities. Although enforced through the justice system, the legacy of the ADA transcends well beyond its legal ramifications. The policy’s framework and the rhetoric of Disability Rights suggest both an embrace of the spirit and the letter of the law, or promulgating both legislative and cultural change to ensure that the rights of people with disabilities are met.  In attempting to understand how and if such change has happened, researchers have gathered extensive evidence since 1990.  Much of this research evidence, however, remains fragmented, under-utilized, and at times inconclusive.  This article presents the results of a rapid evidence review of a sample of such research that is crucial to understand the ADA’s progress.  The study examines evidence about the ADA’s influence on knowledge, attitudes and perceptions about employment of people with disabilities. The research illustrates the importance of moving beyond the law to incorporate changes in knowledge about the law, perceptions of employability, and workplace culture.

  14. Integrating automated structured analysis and design with Ada programming support environments

    Hecht, Alan; Simmons, Andy

    1986-01-01

    Ada Programming Support Environments (APSE) include many powerful tools that address the implementation of Ada code. These tools do not address the entire software development process. Structured analysis is a methodology that addresses the creation of complete and accurate system specifications. Structured design takes a specification and derives a plan to decompose the system subcomponents, and provides heuristics to optimize the software design to minimize errors and maintenance. It can also produce the creation of useable modules. Studies have shown that most software errors result from poor system specifications, and that these errors also become more expensive to fix as the development process continues. Structured analysis and design help to uncover error in the early stages of development. The APSE tools help to insure that the code produced is correct, and aid in finding obscure coding errors. However, they do not have the capability to detect errors in specifications or to detect poor designs. An automated system for structured analysis and design TEAMWORK, which can be integrated with an APSE to support software systems development from specification through implementation is described. These tools completement each other to help developers improve quality and productivity, as well as to reduce development and maintenance costs. Complete system documentation and reusable code also resultss from the use of these tools. Integrating an APSE with automated tools for structured analysis and design provide capabilities and advantages beyond those realized with any of these systems used by themselves.

  16. A Robust AdaBoost.RT Based Ensemble Extreme Learning Machine

    2015-01-01

    Full Text Available Extreme learning machine (ELM has been well recognized as an effective learning algorithm with extremely fast learning speed and high generalization performance. However, to deal with the regression applications involving big data, the stability and accuracy of ELM shall be further enhanced. In this paper, a new hybrid machine learning method called robust AdaBoost.RT based ensemble ELM (RAE-ELM for regression problems is proposed, which combined ELM with the novel robust AdaBoost.RT algorithm to achieve better approximation accuracy than using only single ELM network. The robust threshold for each weak learner will be adaptive according to the weak learner’s performance on the corresponding problem dataset. Therefore, RAE-ELM could output the final hypotheses in optimally weighted ensemble of weak learners. On the other hand, ELM is a quick learner with high regression performance, which makes it a good candidate of “weak” learners. We prove that the empirical error of the RAE-ELM is within a significantly superior bound. The experimental verification has shown that the proposed RAE-ELM outperforms other state-of-the-art algorithms on many real-world regression problems.

    An increase in the mitochondrial (mt) rho^- mutagenesis is a well-known respose of yeast cells to mutations in the numerous nuclear genes as well as to various kinds of stress. Notwithstanding the extensive studies during several decades the biological significance of this response is not yet fully understood. The genetic approach to solution of this subject includes the study of genes that are required for the high incidence of spontaneous rho^- mutants. Previously we found that mutations in certain nuclear genes including CDC28, the central cell-cycle regulation gene, may decrease the spontaneous rho^- mutability and simultaneously affect maintenance of the yeast chromosomes and plasmids. The present work provides data on identification of two more genes, resembling CDC28 in this respect. These genes NET1 and ADA1 mediate important regulatory protein-protein interactions in the yeast cell. The effects of net1 and ada1 mutations on the maintenance of yeast mt genome, chromosomes and plasmids as well as on ce...

    2017-01-01

    Full Text Available In this work is presented a novel approach for passive safety in vehicles by Advanced Driver Assistance Systems (ADAS alert emission in 360° around driver to notify about hazards nearby the vehicle depending on the actions taken by driver per the context. This proposal would create a more robust system compared to current passive ADAS systems since the feedback to driver is in the same direction that hazard is detected (Punctual Sound Source Alert, compared with most assistance systems that emits sounds from the monitor or from the dashboard provoking distractions when emits alerts unnecessarily. The increase of security by this method will allow the driver to be aware of their surroundings even in a very quiet cabin or in a noisy environment. Also, it would detect the steering wheel angle, speed of movement and the activation of turning lights among other alerts, which would allow us to define a critical action during driving; apart from using sensors and cameras aimed at the driver to detect patterns of movement during these critical actions and have a prediction of a possible turn or manoeuvre when driving, refer to Figure 1. It will be necessary a reconfiguration of the alert in frequency, time of action depending upon the level of risk to prevent an accident or to reduce the consequences in an imminent accident.

  1. The neuro-glial properties of adipose-derived adult stromal (ADAS cells are not regulated by Notch 1 and are not derived from neural crest lineage.

    Directory of Open Access Journals (Sweden)

    Philip C Wrage

    Full Text Available We investigated whether adipose-derived adult stromal (ADAS are of neural crest origin and the extent to which Notch 1 regulates their growth and differentiation. Mouse ADAS cells cultured in media formulated for neural stem cells (NSC displayed limited capacity for self-renewal, clonogenicity, and neurosphere formation compared to NSC from the subventricular zone in the hippocampus. Although ADAS cells expressed Nestin, GFAP, NSE and Tuj1 in vitro, exposure to NSC differentiation supplements did not induce mature neuronal marker expression. In contrast, in mesenchymal stem cell (MSC media, ADAS cells retained their ability to proliferate and differentiate beyond 20 passages and expressed high levels of Nestin. In neuritizing cocktails, ADAS cells extended processes, downregulated Nestin expression, and displayed depolarization-induced Ca(2+ transients but no spontaneous or evoked neural network activity on Multi-Electrode Arrays. Deletion of Notch 1 in ADAS cell cultures grown in NSC proliferation medium did not significantly alter their proliferative potential in vitro or the differentiation-induced downregulation of Nestin. Co-culture of ADAS cells with fibroblasts that stably expressed the Notch ligand Jagged 1 or overexpression of the Notch intracellular domain (NICD did not alter ADAS cell growth, morphology, or cellular marker expression. ADAS cells did not display robust expression of neural crest transcription factors or genes (Sox, CRABP2, and TH; and lineage tracing analyses using Wnt1-Cre;Rosa26R-lacZ or -EYFP reporter mice confirmed that fewer than 2% of the ADAS cell population derived from a Wnt1-positive population during development. In summary, although media formulations optimized for MSCs or NSCs enable expansion of mouse ADAS cells in vitro, we find no evidence that these cells are of neural crest origin, that they can undergo robust terminal differentiation into functionally mature neurons, and that Notch 1 is likely to be

    Adkins, Candice B.; Bartolino, James R.

    2010-01-01

    Residents of northern Ada County, Idaho, depend on groundwater for domestic and agricultural uses. The population of this area is growing rapidly and groundwater resources must be understood for future water-resource management. The U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, used a suite of isotopic and environmental tracers to gain a better understanding of groundwater ages, recharge sources, and flowpaths in northern Ada County. Thirteen wells were sampled between September and October 2009 for field parameters, major anions and cations, nutrients, oxygen and hydrogen isotopes, tritium, radiocarbon, chlorofluorocarbons, and dissolved gasses. Well depths ranged from 30 to 580 feet below land surface. Wells were grouped together based on their depth and geographic location into the following four categories: shallow aquifer, intermediate/deep aquifer, Willow Creek aquifer, and Dry Creek aquifer. Major cations and anions indicated calcium-bicarbonate and sodium-bicarbonate water types in the study area. Oxygen and hydrogen isotopes carried an oxygen-18 excess signature, possibly indicating recharge from evaporated sources or water-rock interactions in the subsurface. Chlorofluorocarbons detected modern (post-1940s) recharge in every well sampled; tritium data indicated modern water (post-1951) in seven, predominantly shallow wells. Nutrient concentrations tended to be greater in wells signaling recent recharge based on groundwater age dating, thus confirming the presence of recent recharge in these wells. Corrected radiocarbon results generated estimated residence times from modern to 5,100 years before present. Residence time tended to increase with depth, as confirmed by all three age-tracers. The disagreement among residence times indicates that samples were well-mixed and that the sampled aquifers contain a mixture of young and old recharge. Due to a lack of data, no conclusions about sources of recharge could be drawn

  10. Modeling of functional trunk muscle performance: interfacing ergonomics and spine rehabilitation in response to the ADA.

    1997-10-01

    The combination of increasing costs of musculoskeletal injuries and the implementation of the Americans with Disabilities Act (ADA) has created the need for a more objective functional understanding of dynamic trunk performance. In this study, trunk extensor and flexor strengths were measured as a function of angular position and velocity for 20 subjects performing maximum isometric and isokinetic exertions. Results indicate that trunk strength is significantly influenced by trunk angular position, trunk angular velocity, gender, and direction, as well as by the interaction between trunk angular position and velocity. Three-dimensional surfaces of trunk strength in response to trunk angular position and velocity were constructed for each subject per direction. Such data presentation is more accurate and gives better insight about the strength profile of an individual than does the traditional use of a single strength value. The joint strength capacity profiles may be combined with joint torque requirements from a manual material handling task, such as a lifting task, to compute the dynamic utilization ratio for the trunk muscles. This ratio can be used as a unified measure of both task demand and functional capacity to guide job assignment, return to work, and prognosis during the rehabilitation processes. Furthermore, the strength regressions developed in this study would provide dynamic strength limits that can be used as functional constraints in the computer simulation of physical activities, such as lifting. In light of the ADA, this would be of great value in predicting the consequences of task modifications and/or workstation alterations without subjecting an injured worker or an individual with a disability to unnecessary testing.

    To determine whether there exists an additional pathway of E6 that is independent of direct P53 degradation and whether hADA3, a transcriptional coactivator, is involved in this process. We investigated the association between E6 and hADA3, as well as E6-associated protein (E6AP) and hADA3, in SiHa cells via RNA interference technique. Our results showed that the expression of hADA3 protein was significantly increased, cellular proliferation was decreased and apoptotic rate was increased in SiHa cells treated by E6 siRNA and E6AP siRNA respectively. Our results suggested that oncoprotein E6 inhibits hADA3 in cervical cancer cells and this process is E6AP-dependent.

    Full Text Available The human error has been reported as a major root cause in road accidents in today’s world. The human as a driver in road vehicles composed of human, mechanical and electrical components is constantly exposed to changing surroundings (e.g., road conditions, environmentwhich deteriorate the driver’s capacities leading to a potential accident. The auto industries and transportation authorities have realized that similar to other complex and safety sensitive transportation systems, the road vehicles need to rely on both advanced technologies (i.e., Advanced Driver Assistance Systems (ADAS and Passive Safety Systems (PSS (e.g.,, seatbelts, airbags in order to mitigate the risk of accidents and casualties. In this study, the advantages and disadvantages of ADAS as active safety systems as well as passive safety systems in road vehicles have been discussed. Also, this study proposes models that analyze the interactions between human as a driver and ADAS Warning and Crash Avoidance Systems and PSS in the design of vehicles. Thereafter, the mathematical models have been developed to make reliability prediction at any given time on the road transportation for vehicles equipped with ADAS and PSS. Finally, the implications of this study in the improvement of vehicle designs and prevention of casualties are discussed.

    Geomorphosites and geoturism studies are increasing for the high scientific, societal, cultural, and aesthetic values of the relief. Volcanic areas are exciting targets for such studies for their geodiversity. The aim of these study is an inventory of volcanic geomorphosites and its relationship to geotourism. Las Cañadas del Teide National Park (LCTNP) is a volcanic complex area located in the central part of Tenerife island (Canary Islands, Spain). This area is a volcanic paradise rich in spectacular landforms: stratovolcanoes, calderas, cinder cones, craters, pahoehoe, aa, block and balls lavas, gullies, etc. The national park is registered in the world heritage list (UNESCO) in 2007 as a natural site. The LCTNP receives more than 2,5 million tourists per year and it has 21 main pahts and 14 secondary ones. For the selection of the geomophosites the LCTNP was divided into four geomorphological units (Teide-Pico Viejo stratovolcanoes, Las Cañadas Caldera wall, the bottom of Las Cañadas and the basaltic volcanic field) and each one of them is selected the most representative geomorphosites by its geodiversity, because of its geomorphological heritage, its landscapes and its tourist potential with the paths. All selected geomorphosites are within areas where public use is allowed in the park. The inventory classifies the 23 geomorphosites in two main categories: (a) direct volcanic with 17 geomorphosites (stratovolcanoes, domes, cinder cones, pahoehoe, aa and bloc lava flows, etc.) and (b) eroded volcanic landforms with 6 (wall of Las Cañadas caldera, talusees, foodplains, etc.). The Teide-Pico Viejo unit is which has more geomorphosites with 8 and the Las Cañadas wall unit possessing less with 5. The assessment evaluates the scientific, cultural/historical, and use values and helps to define priorities in site management. These geomorphosites demonstrate the volcanic history and processes of the LCTNP.

    Full Text Available This paper presents a non-intrusive approach for monitoring driver drowsiness using the fusion of several optimized indicators based on driver physical and driving performance measures, obtained from ADAS (Advanced Driver Assistant Systems in simulated conditions. The paper is focused on real-time drowsiness detection technology rather than on long-term sleep/awake regulation prediction technology. We have developed our own vision system in order to obtain robust and optimized driver indicators able to be used in simulators and future real environments. These indicators are principally based on driver physical and driving performance skills. The fusion of several indicators, proposed in the literature, is evaluated using a neural network and a stochastic optimization method to obtain the best combination. We propose a new method for ground-truth generation based on a supervised Karolinska Sleepiness Scale (KSS. An extensive evaluation of indicators, derived from trials over a third generation simulator with several test subjects during different driving sessions, was performed. The main conclusions about the performance of single indicators and the best combinations of them are included, as well as the future works derived from this study.

    MicroRNAs play important roles in most biological processes, including cell proliferation, tissue differentiation, and embryonic development, among others. They originate from precursor transcripts (pre-miRNAs), which contain phylogenetically conserved stem-loop structures. An important bioinformatics problem is to distinguish the pre-miRNAs from pseudo pre-miRNAs that have similar stem-loop structures. We present here a novel method for tackling this bioinformatics problem. Our method, named MirID, accepts an RNA sequence as input, and classifies the RNA sequence either as positive (i.e., a real pre-miRNA) or as negative (i.e., a pseudo pre-miRNA). MirID employs a feature mining algorithm for finding combinations of features suitable for building pre-miRNA classification models. These models are implemented using support vector machines, which are combined to construct a classifier ensemble. The accuracy of the classifier ensemble is further enhanced by the utilization of an AdaBoost algorithm. When compared with two closely related tools on twelve species analyzed with these tools, MirID outperforms the existing tools on the majority of the twelve species. MirID was also tested on nine additional species, and the results showed high accuracies on the nine species. The MirID web server is fully operational and freely accessible at http://bioinformatics.njit.edu/MirID/ . Potential applications of this software in genomics and medicine are also discussed.

    2015-01-01

    Full Text Available Background & objectives: Pleural effusion is a common occurrence in patients with late-stage chronic kidney disease (CKD. In developing countries, many effusions remain undiagnosed after pleural fluid analysis (PFA and patients are empirically treated with antitubercular therapy. The aim of this study was to evaluate the role of adenosine deaminase (ADA, nucleic acid amplification tests (NAAT and medical thoracoscopy in distinguishing tubercular and non-tubercular aetiologies in exudative pleural effusions complicating CKD. Methods: Consecutive stage 4 and 5 CKD patients with pleural effusions underwent PFA including ADA and PCR [65 kDa gene; multiplex (IS6110, protein antigen b, MPB64]. Patients with exudative pleural effusion undiagnosed after PFA underwent medical thoracoscopy. Results: All 107 patients underwent thoracocentesis with 45 and 62 patients diagnosed as transudative and exudative pleural effusions, respectively. Twenty six of the 62 patients underwent medical thoracoscopy. Tuberculous pleurisy was diagnosed in six while uraemic pleuritis was diagnosed in 20 subjects. The sensitivity and specificity of pleural fluid ADA, 65 kDa gene PCR, and multiplex PCR were 66.7 and 90 per cent, 100 and 50 per cent, and 100 and 100 per cent, respectively. Thoracoscopy was associated with five complications in three patients. Interpretation & conclusions: Uraemia remains the most common cause of pleural effusion in CKD even in high TB prevalence country. Multiplex PCR and thoracoscopy are useful investigations in the diagnostic work-up of pleural effusions complicating CKD while the sensitivity and/or specificity of ADA and 65 kDa gene PCR is poor.

    The aim of this study was to evaluate the effect of zinc supplementation on the ecto-adenosine deaminase activity (E-ADA), zinc seric levels and cytokines (TNF-α, IL-1, IL-6, and IL -10) on rats experimentally infected by Trypanosoma evansi. Four groups with 10 rats each were used as negative controls (groups A and B), while the animals from the groups C and D were infected intraperitoneally with 0.1 mL of cryopreserved blood containing 1.4 × 10(4) of trypanosomes. Animals of groups B and D received two doses of Zinc (Zn) at 5 mg kg(-1), subcutaneously, on the 2nd and 7th day post-infection (PI). Blood samples were collected on days 5 (n = 5) and 15 PI (n = 5). Zn supplementation was able to increase the rat's longevity and to reduce their parasitemia. It was observed that seric Zn levels were increased on infected animals under Zn supplementation. Animals that were infected and supplemented with Zn showed changes in E-ADA activity and in cytokine levels (P < 0.05). Zn supplementation of healthy animals (Group B), increased the E-ADA activity, as well as reduced the concentration of cytokines. Infected animals from groups C and D showed increased levels of cytokines. Finally, we observed that Zn supplementation led to a modulation on cytokine's level in rats infected by T. evansi, as well as in E-ADA activity.

An AdaBoost face detection algorithm is proposed based on wavelet recon-struction and feature extraction, and it is applied in identity verification. By using the wavelet reconstruction method, the re-construction of useful face information features is obtained, denoising processing is used to improve the accuracy of face recognition. The facial feature relevance method is used, and the different features of face are classified in different sets. The feature extraction algorithm is used to improve the AdaBoost face detection algorithm. Simulation results show that,the new method can detect the non frontal face image features within a certain range, and the detection precision and accurate recognition rate are improved.

  15. Flow and linear coefficient of thermal expansion of four types of Base Plate waxes compared with ADA standard

    Full Text Available Waxes have a lot of applications in dentistry. Such materials are of thermoplastic type that undergoes deformation in different temperatures. Two important properties of base plate waxes are flow and their coefficient of linear thermal expansion. Recently, different institutions, inside the country, produce dentistry waxes, while they have not been standardized. Consequently, consumers' dissatisfaction are observed. In this research, the two above- mentioned factors were compared between three kinds of Iranian waxes with Cavex that is foreign production, based on test number 24 of ADA. To measure the flow rate in the temperatures of 23, 37 and 45°c, Wilcoxon statistical analysis was used. The results showed that in 23°c, the flow rate of Cavex and Azardent waxes met ADA standards; however, it was not true for two others types. In 37°c, the flow of none of the waxes was standardized and in 45°c their flow was acceptable, moreover, thermal expansion coefficient, for Cavex and Azardent types, was based on ADA standard.

  16. An improved gravity compensation method for high-precision free-INS based on MEC-BP-AdaBoost

    2016-12-01

    In recent years, with the rapid improvement of inertial sensors (accelerometers and gyroscopes), gravity compensation has become more important for improving navigation accuracy in inertial navigation systems (INS), especially for high-precision INS. This paper proposes a mind evolutionary computation (MEC) back propagation (BP) AdaBoost algorithm neural-network-based gravity compensation method that estimates the gravity disturbance on the track based on measured gravity data. A MEC-BP-AdaBoost network-based gravity compensation algorithm used in the training process to establish the prediction model takes the carrier position (longitude and latitude) provided by INS as the input data and the gravity disturbance as the output data, and then compensates the obtained gravity disturbance into the INS’s error equations to restrain the position error propagation. The MEC-BP-AdaBoost algorithm can not only effectively avoid BP neural networks being trapped in local extrema, but also perfectly solve the nonlinearity between the input and output data that cannot be solved by traditional interpolation methods, such as least-square collocation (LSC) interpolation. The accuracy and feasibility of the proposed interpolation method are verified through numerical tests. A comparison of several other compensation methods applied in field experiments, including LSC interpolation and traditional BP interpolation, highlights the superior performance of the proposed method. The field experiment results show that the maximum value of the position error can reduce by 28% with the proposed gravity compensation method.

    A patient with adenosine deaminase-deficient severe combined immune deficiency (ADA-SCID) was enrolled in a study of retroviral-mediated ADA gene transfer to bone marrow hematopoietic stem cells. After the discontinuation of ADA enzyme replacement, busulfan (75 mg/m2) was administered for bone marrow cytoreduction, followed by infusion of autologous, gene-modified CD34+ cells. The expected myelosuppression developed after busulfan but then persisted, necessitating the administration of untransduced autologous bone marrow back-up at day 40. Because of sustained pancytopenia and negligible gene marking, diagnostic bone marrow biopsy and aspirate were performed at day 88. Analyses revealed hypocellular marrow and, unexpectedly, evidence of trisomy 8 in 21.6% of cells. Trisomy 8 mosaicism (T8M) was subsequently diagnosed by retrospective analysis of a pretreatment marrow sample that might have caused the lack of hematopoietic reconstitution. The confounding effects of this preexisting marrow cytogenetic abnormality on the response to gene transfer highlights another challenge of gene therapy with the use of autologous hematopoietic stem cells.

    Fabrications of a single layer organic light emitting diodes (OLEDs) based on two conjugated acceptor-donor-acceptor (ADA) isatin Schiff bases are described. The electroluminescent spectra of these materials range from 630 to 700 nm and their band gaps were measured between 1.97 and 1.77 eV. The measured maximum external quantum efficiencies (EQE) for fabricated OLEDs are 0.0515% and 0.054% for two acceptor-donor-acceptor chromophores. The Commission International De L'Eclairage (CIE) (1931) coordinates of these two compounds were attained and found to be (0.4077, 0.4128) and (0.4411, 0.4126) for two used acceptor-donor-acceptor chromophores. The measured I-V curves demonstrated the apparent diode behavior of two ADA chromophores. The turn-on voltages in these OLEDs are directly dependent on the thickness. These results have demonstrated that ADA isatin Schiff bases could be considered as promising electroluminescence-emitting materials for fabrication of OLEDs.

    2016-06-01

    The present study is aimed at characterizing the subsurface geological and tectonic structure in Deir El-Adas area, by using Vertical Electrical Sounding survey (VES) and hydrogeological investigations, in order to determine the causes of the failure for the majority of the wells drilled in the area. The survey data was treated in three different approaches including direct VES inversion, pseudo-2D method and horizontal profiling, in order to maximize the reliability of the data interpretation. The results revealed the presence of a local faulted anticline structure at the top of the Paleogene formation, underneath the basaltic outcrops where Deir El-Adas village is situated. The appearance of this subsurface anticline structure has complicated the local hydro-geological situation, and most likely led to limitation of the groundwater recharge in the area. Moreover, the performed piezometric and discharge maps indicated the presence of a notable groundwater watershed, in addition to feeble water productivity of the wells drilled adjacent to Deir El-Adas, mostly related to the subsurface geological and tectonic settings in the area.

    1989-03-01

    The success of the Strategic Defense Initiative depends directly on significant advances in both computer hardware and software development technologies. Parallel architectures and the Ada programming language have advantages that make them candidates for use in SDI command and control computer systems. This thesis examines those advantages in the context of an SDI-type application: implementation of a Kalman-filter tracking system. This research consists of three parts.

    Electron-accepting molecules play an important role in developing organic solar cells. A new type of A-D-A molecule, 3,6-di([7-(5-bromothiophen-2-yl)-1,5,2,4,6,8-dithiotetrazocin-3-yl]thiophen-2-yl)-9-(2-ethylhexyl)carbazole, was synthesized. The lowest unoccupied molecular orbital (LUMO) and highest occupied molecular orbital (HOMO) energy levels are -3.55 and -5.85 eV, respectively. Therefore, the A-D-A type of compound could be used as electron acceptor for fabricating organic solar cell with a high open circuit voltage. Gibbs free energy (-49.2 kJ/mol) reveals that the process of A-D-A acceptor accepting an electron from poly(3-hexylthiophene) at excited state is spontaneous. The value of entropy (118 J/mol) in the process of an electron transferring from P3HT to the A-D-A acceptor at organic interface suggests that electrons generated from separation of electron-hole pairs at donor/acceptor interface would be delocalized efficiently. Therefore, the A-D-A molecule would be a potential acceptor for efficient organic BHJ solar cells.

Com base na perspectiva histórico-cultural sobre aprendizagem, argumentamos contra a competitividade e a favor da colaboração nos processos educativos. A partir de análises da desigualdade escolar balizadas pela sociologia da educação, colocamo-nos contra a competição injusta entre estudantes já pré-selecionados por seu capital cultural. Defendemos que a interação, a colaboração e a democracia são valores defensáveis tanto do ponto de vista cognitivo ou educativo quanto do ponto de vista da formação humana.

  16. DELTA: A Distal Enhancer Locating Tool Based on AdaBoost Algorithm and Shape Features of Chromatin Modifications.

    Yiming Lu

    Full Text Available Accurate identification of DNA regulatory elements becomes an urgent need in the post-genomic era. Recent genome-wide chromatin states mapping efforts revealed that DNA elements are associated with characteristic chromatin modification signatures, based on which several approaches have been developed to predict transcriptional enhancers. However, their practical application is limited by incomplete extraction of chromatin features and model inconsistency for predicting enhancers across different cell types. To address these issues, we define a set of non-redundant shape features of histone modifications, which shows high consistency across cell types and can greatly reduce the dimensionality of feature vectors. Integrating shape features with a machine-learning algorithm AdaBoost, we developed an enhancer predicting method, DELTA (Distal Enhancer Locating Tool based on AdaBoost. We show that DELTA significantly outperforms current enhancer prediction methods in prediction accuracy on different datasets and can predict enhancers in one cell type using models trained in other cell types without loss of accuracy. Overall, our study presents a novel framework for accurately identifying enhancers from epigenetic data across multiple cell types.

    Full Text Available License plate (LP detection is the most imperative part of the automatic LP recognition system. In previous years, different methods, techniques, and algorithms have been developed for LP detection (LPD systems. This paper proposes to automatical detection of car LPs via image processing techniques based on classifier or machine learning algorithms. In this paper, we propose a real-time and robust method for LPD systems using the two-stage adaptive boosting (AdaBoost algorithm combined with different image preprocessing techniques. Haar-like features are used to compute and select features from LP images. The AdaBoost algorithm is used to classify parts of an image within a search window by a trained strong classifier as either LP or non-LP. Adaptive thresholding is used for the image preprocessing method applied to those images that are of insufficient quality for LPD. This method is of a faster speed and higher accuracy than most of the existing methods used in LPD. Experimental results demonstrate that the average LPD rate is 98.38% and the computational time is approximately 49 ms.

    Sickle cell anemia (SCA) is a hemoglobinopathy characterized by hemolysis and vaso-occlusions caused by rigidly distorted red blood cells. Sickle cell crisis is associated with extracellular release of nucleotides and platelets, which are critical mediators of hemostasis participating actively in purinergic thromboregulatory enzymes system.This study aimed to investigate the activities of purinergic system ecto-enzymes present on the platelet surface as well as CD39 and CD73 expressions on platelets of SCA treated patients. Fifteen SCA treated patients and 30 health subjects (control group) were selected. Ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase), ecto-5'-nucleotidase (E-5'-NT) and ecto-adenosine deaminase (E-ADA) activities were measured in platelets isolated from these individuals. Results demonstrated an increase of 41 % in the E-NTPDase for ATP hydrolysis, 52% for ADP hydrolysis and 60 % in the E-ADA activity in SCA patients (P<0.05); however, a two folds decrease in the CD39 expression in platelets was observed in the same group (P<0.01). The increased E-NTPDase activity could be a compensatory mechanism associated with the low expression of CD39 in platelets. Besides, alteration of these enzymes activities suggests that the purinergic system could be involved in the thromboregulatory process in SCA patients.

    Automatic recognition of epilepsy electroencephalography (EEG) signal has become a research focus because of its high efficiency, and many algorithms have been put forward to achieve it. As one of the classic algorithms of boosting algorithm, AdaBoost algorithm has been widely used in face detection and target tracking fields, but the algorithm also has a disadvantage that is its degradation. In order to solve this problem, this paper puts forward three measures to optimize the algorithm by filtering the weak classifiers whose recognition rates are low, introducing the smoothing factor and a weighted correction function. In order to verify the robustness of optimized algorithm, we choose three main parameters, i.e., the number of weak classifier, which is denoted by T;the base of logarithmic function, which is denoted byα;the threshold of weight, which is denoted byβ. The experimental results of optimized AdaBoost show that it has good robustness and high recognition rate. In this paper, we divide the whole process into three steps. The first step is to use the Butterworth digital low-pass filter in which the cutoff frequency of pass band is 40 Hz to filter noise whose frequency is above 40 Hz. The second step is to do feature extraction with the help of wavelet packet decomposition. The third step is to compute the sum of absolute value which are the wavelet packet coefficients of fourth layer, the wavelet package entropy and the sum of signal amplitude square and combine them together to form the feature vector of each EEG. Because the wavelet package entropy is far less than the sum of absolute value and the sum of signal amplitude square, in order to make sure that the entropy reacts in the third step, we use one thousandth of the sum of absolute wavelet packet coefficients, one hundredth of the sum of signal amplitude square and the wavelet package entropy as the weighted feature vector. Finally, we succeed in distinguishing EEGs between epilepsy and normal

    Herein we report astronomical observations made with the NASA Advanced Data Acquisition System (ADAS). The NASA ADAS antenna, located at NASA Goddard Spaceflight Center's Wallops Flight Facility, Virginia, is an 18-meter X-band antenna system that has been primarily used for satellite tracking and served as the telecommunication station for the NASA IUE satellite until ca. 1997. A joint NASA-Morehead State University (MSU)-Kentucky NSF EPSCoR venture has been initiated to upgrade and relocate the antenna system to MSU's Astrophysics Laboratory where it will provide a research instrument and active laboratory for undergraduate students as well as be engaged in satellite tracking missions. As part of the relocation efforts, many systems will be upgraded including replacement of a hydrostatic azimuth bearing with a high-precision electromechanical bearing, a new servo system, and Ku-capable reflector surface. It is widely believed that there are still contributions that small aperture centimeter-wave instruments can make utilizing three primary observing strategies: 1.) longitudinal studies of RF variations in cosmic phenomena, 2.) surveys of large areas of sky, and 3.) fast reactions to transient phenomena. MSU faculty and staff along with NASA engineers re-outfitted the ADAS system with RF systems and upgraded servo controllers during the spring and summer of 2001. Empirical measurements of primary system performance characteristics were made including G/T (at S- and L bands), noise figures, pointing and tracking accuracies, and drive speeds and accelerations. Baseline astronomical observations were made with the MSU L-band receiver using a 6 MHz bandwidth centered at 1420 MHz (21-cm) and observing over a range of frequencies (up to 2.5 MHz, tunable over the 6 MHz window) with a 2048-channel back-end spectrometer, providing up to 1 KHz frequency resolution. Baseline observations of radio sources herein reported include Cygnus A, 3C 157, 3C 48 and the Andromeda

    Locating multi-view faces in images with a complex background remains a challenging problem. In this paper, an integrated method for real-time multi-view face detection and pose estimation is presented. A simple-to-complex and coarse-to-fine view-based detector architecture has been designed to detect multi-view faces and estimate their poses efficiently. Both the pose estimators and the view-based face/nonface detectors are trained by a cost-sensitive AdaBoost algorithm to improve the generalization ability. Experimental results show that the proposed multi-view face detector, which can be constructed easily, gives more robust face detection and pose estimation and has a faster real-time detection speed compared with other conventional methods.

    Full Text Available The automatic fruit detection and precision picking in unstructured environments was always a difficult and frontline problem in the harvesting robots field. To realize the accurate identification of grape clusters in a vineyard, an approach for the automatic detection of ripe grape by combining the AdaBoost framework and multiple color components was developed by using a simple vision sensor. This approach mainly included three steps: (1 the dataset of classifier training samples was obtained by capturing the images from grape planting scenes using a color digital camera, extracting the effective color components for grape clusters, and then constructing the corresponding linear classification models using the threshold method; (2 based on these linear models and the dataset, a strong classifier was constructed by using the AdaBoost framework; and (3 all the pixels of the captured images were classified by the strong classifier, the noise was eliminated by the region threshold method and morphological filtering, and the grape clusters were finally marked using the enclosing rectangle method. Nine hundred testing samples were used to verify the constructed strong classifier, and the classification accuracy reached up to 96.56%, higher than other linear classification models. Moreover, 200 images captured under three different illuminations in the vineyard were selected as the testing images on which the proposed approach was applied, and the average detection rate was as high as 93.74%. The experimental results show that the approach can partly restrain the influence of the complex background such as the weather condition, leaves and changing illumination.

    To improve maintenance and gene transfer of human lymphoid progenitors for clinical use in gene therapy of adenosine deaminase (ADA)-deficient SCID we investigated several gene transfer protocols using various stem cell-enriched sources. The lymphoid differentiation potential was measured by an in vitro clonal assay for B/NK cells and in the in vivo SCID-hu mouse model. Ex vivo culture with the cytokines TPO, FLT3-ligand, and SCF (T/F/S) plus IL-3 or IL-7 substantially increased the yield of transduced bone marrow (BM) CD34(+) cells purified from ADA-SCID patients or healthy donors, compared to T/F/S alone. Moreover, the use of IL-3 or IL-7 significantly improved the maintenance of in vitro B cell progenitors from ADA-SCID BM cells and allowed the efficient transduction of B and NK cell progenitors. Under these optimized conditions transduced CD34(+) cells were efficiently engrafted into SCID-hu mice and gave rise to B and T cell progeny, demonstrating the maintenance of in vivo lymphoid reconstitution capacity. The protocol based on the T/F/S + IL-3 combination was included in a gene therapy clinical trial for ADA-SCID, resulting in long-term engraftment of stem/progenitor cells. Remarkably, gene-corrected BM CD34(+) cells obtained from one patient 4 and 11 months after gene therapy were capable of repopulating the lymphoid compartment of SCID-hu hosts.

    Sickle cell anemia (SCA) is characterized by hemoglobin polymerization that results in sickle-shaped red blood cells. The vascular obstruction by sickle erythrocytes is often inflammatory, and purinergic system ecto-enzymes play an important role in modulating the inflammatory and immune response. This study aimed to evaluate the E-NTPDase and E-ADA activities in lymphocytes of SCA treated patients, as well as verify the cytokine profile in this population. Fifteen SCA treated patients and 30 health subjects (control group) were selected. The peripheral lymphocytes were isolated and E-NTPDase and E-ADA activities were determined. Serum was separated from clot formation for the cytokines quantification. E-NTPDase (ATP and ADP as substrate) and E-ADA (adenosine as substrate) activities were increased in lymphocytes from SCA patients (P<0.001). The TNF-α and IL-6 serum cytokines showed decreased on SCA patients comparing to control (P<0.001). The regulation of extracellular nucleotides released in response to hypoxia and inflammation through E-NTPDase and E-ADA enzymes represent an important control of purine-mediated in the SCA disease, avoiding elevated adenosine levels in the extracellular medium and consequent organ injuries in these patients. The pro-inflammatory cytokines decreased levels by use of hydroxyurea occur in attempt to reduce the pro-inflammatory response and prevent vaso-oclusive crisis.

    Fusarium verticillioides is an important plant pathogenic fungus causing maize ear and stalk rots. In addition, the fungus is directly associated with fumonisin contamination of food and feeds. Here, we report the functional characterization of Ada1, a putative Cys2-His2 zinc finger transcription factor with a high level of similarity to Aspergillus nidulans FlbC, which is required for the activation of the key regulator of conidiation brlA. ADA1 is predicted to encode a protein with two DNA binding motifs at the C terminus and a putative activator domain at the N terminus region. Deletion of the flbC gene in A. nidulans results in "fluffy" cotton-like colonies, with a defect in transition from vegetative growth to asexual development. In this study we show that Ada1 plays a key role in asexual development in F. verticillioides. Conidia production was significantly reduced in the knockout mutant (Δada1), in which aberrant conidia and conidiophores were also observed. We identified genes that are predicted to be downstream of ADA1, based on A. nidulans conidiation signaling pathway. Among them, the deletion of stuA homologue, FvSTUA, resulted in near absence of conidia production. To further investigate the functional conservation of this transcription factor, we complemented the Δada1 strain with A. nidulans flbC, F. verticillioides ADA1, and chimeric constructs. A. nidulans flbC failed to restore conidia production similar to the wild-type level. However, the Ada1N-terminal domain, which contains a putative activator, fused to A. nidulans FlbC C-terminal motif successfully complemented the Δada1 mutant. Taken together, Ada1 is an important transcriptional regulator of asexual development in F. verticillioides and that the N-terminus domain is critical for proper function of this transcription factor.

    首先给出了通过矩形块与三角像素特征块相结合所构造的八种用于眼睛检测的扩展三角特征原型块.考虑扫描块在人脸背景中遍历时眼睛样本图像块数量远少于非眼睛样本块数的实际,提出了一种结合Haar特征和三角特征的AdaBoost快速眼睛检测算法.通过级联分类器的前几层强分类器完成排除大部分非眼睛样本;然后,通过后续强分类器进行判断大部分的眼睛图像块和少量非眼睛图像块.检测时间消耗有所下降,这样可以保证整体的检测速度.实验结果进一步表明该算法具有更好的检测性能,与仅使用Haar特征相比正检率有一定程度提高.%Eight extended feature prototypes were presented by combining rectangular feature blocks and triangular feature blocks. In consideration of the fact that the amount of eye image blocks is far less than that of non-eye image blocks during a scanning block passing through face images, a fast eye location detection scheme based on AdaBoost algorithm combining rectangular feature blocks and triangular feature blocks was proposed. After most of non-eye blocks are excluded through the foregoing strong classifiers, most eye image blocks and a few of non-eye image blocks are detected through the rear parts of the cascade classifier, which can reduce the detection time and boost the detection speed. The experiments further show that the scheme has better detection performance and positive detection rate compared to the case only employed Haar features.

    Climate change (CC) scenarios for the Mediterranean region include an increase in the frequency and intensity of extreme weather events such as drought periods. higher average temperatures and evapotranspiration, combined with the decrease of annual precipitation may strongly affect the sustainability of water resources. In face of these risks, improving water management actions? by anticipating necessary operational measures is required to insure water quantity and quality according to the needs of the populations and irrigation in agriculture. This is clearly the case of the Alentejo region, southern Portugal, where present climatic conditions already pose significant challenges to water resources stakeholders, mainly from the agricultural and the urban supply sectors. With this in mind, the GestAqua.AdaPT project is underway during 2015 and 2016, aiming at analyzing CC impacts until 2100 and develop operational procedures to ensure water needs are adequately satisfied in the Monte Novo and Vigia reservoirs, which supply water for the city of Évora and nearby irrigation systems. Specific project objectives include: a) defining management and operational adaptation strategies aiming to ensure resource sustainability, both quantitatively and qualitatively; b) evaluate future potential costs and available alternatives to the regional water transfer infrastructure linked with the large Alqueva reservoir implemented in 2011; c) defining CC adaptation strategies to reduce irrigation water needs and d) identification of CC adaptation strategies which can be suitable also to other similar water supply systems. The methodology is centered on the implementation of a cascade of modeling tools, allowing the integrated simulation of the multiple variables under analysis. The project is based on CC scenarios resulting from the CORDEX project for 10 combinations of Global and regional climate models (GCMs and RCMs). The study follows by using two of these combinations

  17. Aquifer Recharge Estimation through Atmospheric Chloride Mass Balance at Las Cañadas Caldera, Tenerife, Canary Islands, Spain

    Rayco Marrero-Diaz

    2015-05-01

    Full Text Available The atmospheric chloride mass balance (CMB method was used to estimate net aquifer recharge in Las Cañadas Caldera, an endorheic summit aquifer area about 2000 m a.s.l. with negligible surface runoff, which hosts the largest freshwater reserve in Tenerife Island, Canary Islands, Spain. The wet hydrological year 2005–2006 was selected to compare yearly atmospheric chloride bulk deposition and average chloride content in recharge water just above the water table, both deduced from periodical sampling. The potential contribution of chloride to groundwater from endogenous HCl gas may invalidate the CMB method. The chloride-to-bromide molar ratio was an efficient tracer used to select recharge water samples having atmospheric origin of chloride. Yearly net aquifer recharge was 631 mm year−1, i.e., 69% of yearly precipitation. This result is in agreement with potential aquifer recharge estimated through an independent lumped-parameter rainfall-runoff model operated by the Insular Water Council of Tenerife. This paper illustrates basic procedures and routines to use the CMB method for aquifer recharge in active volcanic oceanic islands having sparse-data coverage and groundwater receiving contribution of endogenous halides.

    1995-01-01

    This document describes the software designed to provide communication between control computers in the NASA Lewis Research Center Electrical Power System Testbed using MIL-STD-1553B. The software drivers are coded in the Ada programming language and were developed on a MSDOS-based computer workstation. The Electrical Power System (EPS) Testbed is a reduced-scale prototype space station electrical power system. The power system manages and distributes electrical power from the sources (batteries or photovoltaic arrays) to the end-user loads. The electrical system primary operates at 120 volts DC, and the secondary system operates at 28 volts DC. The devices which direct the flow of electrical power are controlled by a network of six control computers. Data and control messages are passed between the computers using the MIL-STD-1553B network. One of the computers, the Power Management Controller (PMC), controls the primary power distribution and another, the Load Management Controller (LMC), controls the secondary power distribution. Each of these computers communicates with two other computers which act as subsidiary controllers. These subsidiary controllers are, in turn, connected to the devices which directly control the flow of electrical power.

    The current computer-aided detection (CAD) methods are not sufficiently accurate in detecting masses, especially in dense breasts and/or small masses (typically at their early stages). A small mass may not be perceived when it is small and/or homogeneous with surrounding tissues. Possible reasons for the limited performance of existing CAD methods are lack of multiscale analysis and unification of variant masses. The speed of CAD analysis is important for field applications. We propose a new CAD model for mass detection, which extracts simple Haar-like features for fast detection, uses AdaBoost approach for feature selection and classifier training, applies cascading classifiers for reduction of false positives, and utilizes multiscale detection for variant sizes of masses. In addition to Haar features, local binary pattern (LBP) and histograms of oriented gradient (HOG) are extracted and applied to mass detection. The performance of a CAD system can be measured with true positive rate (TPR) and false positives per image (FPI). We are collecting our own digital mammograms for the proposed research. The proposed CAD model will be initially demonstrated with mass detection including architecture distortion.

  1. The covariant description of electric and magnetic field lines of null fields: application to Hopf-Rañada solutions

    van Enk, S. J.

    2013-05-01

    The concept of electric and magnetic field lines is intrinsically non-relativistic. Nonetheless, for certain types of fields satisfying certain geometric properties, field lines can be defined covariantly. More precisely, two Lorentz-invariant 2D surfaces in spacetime can be defined such that magnetic and electric field lines are determined, for any observer, by the intersection of those surfaces with spacelike hyperplanes. An instance of this type of field is constituted by the so-called Hopf-Rañada solutions of the source-free Maxwell equations, which have been studied because of their interesting topological properties, namely, linkage of their field lines. In order to describe both geometric and topological properties in a succinct manner, we employ the tools of geometric algebra (aka Clifford algebra) and use the Clebsch representation for the vector potential as well as the Euler representation for both magnetic and electric fields. This description is easily made covariant, thus allowing us to define electric and magnetic field lines covariantly in a compact geometric language. The definitions of field lines can be phrased in terms of 2D surfaces in space. We display those surfaces in different reference frames, showing how those surfaces change under Lorentz transformations while keeping their topological properties. As a byproduct we also obtain relations between optical helicity, optical chirality and generalizations thereof, and their conservation laws.

  2. Depth and Intensity Gabor Features Based 3D Face Recognition Using Symbolic LDA and AdaBoost

    Directory of Open Access Journals (Sweden)

    2013-11-01

    Full Text Available In this paper, the objective is to investigate what contributions depth and intensity information make to the solution of face recognition problem when expression and pose variations are taken into account, and a novel system is proposed for combining depth and intensity information in order to improve face recognition performance. In the proposed approach, local features based on Gabor wavelets are extracted from depth and intensity images, which are obtained from 3D data after fine alignment. Then a novel hierarchical selecting scheme embedded in symbolic linear discriminant analysis (Symbolic LDA with AdaBoost learning is proposed to select the most effective and robust features and to construct a strong classifier. Experiments are performed on the three datasets, namely, Texas 3D face database, Bhosphorus 3D face database and CASIA 3D face database, which contain face images with complex variations, including expressions, poses and longtime lapses between two scans. The experimental results demonstrate the enhanced effectiveness in the performance of the proposed method. Since most of the design processes are performed automatically, the proposed approach leads to a potential prototype design of an automatic face recognition system based on the combination of the depth and intensity information in face images.

    1989-10-01

    Sewage-contaminated natural seawater was analysed for the presence of motile Aeromonas by two membrane filtration procedures. Incubation of membranes on two modified media (mADA (0/129) and mSA (0/129) were compared. The specificity of the two media was high, 95.8% on mADA (0/129) and 94.8% on mSA (0129). The most frequent species identified were A. caviae, followed by A. hydrophila and A. sobria. Motile Aeromonas counts were high in both media (greater than 10(4)/100 ml) and no significant differences were observed between them. The two membrane filtration procedures allowed rapid quantitative recovery of motile Aeromonas from seawater in the presence of very large numbers of competing microflora.

    2010-01-01

    The ADA and the EASD recently published a consensus statement for the medical management of hyperglycaemia in patients with type 2 diabetes. The authors advocate initial treatment with metformin monotherapy and lifestyle modification, followed by addition of basal insulin or a sulfonylurea if glycaemic goals are not met (tier 1 recommendations). All other glucose-lowering therapies are relegated to a secondary (tier 2) status and only recommended for selected clinical settings. In our view, this algorithm does not offer physicians and patients the appropriate selection of options to individualise and optimise care with a view to sustained control of blood glucose and reduction both of diabetes complications and cardiovascular risk. This paper critically assesses the basis of the ADA/EASD algorithm and the resulting tiers of treatment options. PMID:20352408

  12. A non-sense mutation in the putative anti-mutator gene ada/alkA of Mycobacterium tuberculosis and M. bovis isolates suggests convergent evolution

    Directory of Open Access Journals (Sweden)

    Gicquel Brigitte

    2007-05-01

    Full Text Available Abstract Background Previous studies have suggested that variations in DNA repair genes of W-Beijing strains may have led to transient mutator phenotypes which in turn may have contributed to host adaptation of this strain family. Single nucleotide polymorphism (SNP in the DNA repair gene mutT1 was identified in MDR-prone strains from the Central African Republic. A Mycobacteriumtuberculosis H37Rv mutant inactivated in two DNA repair genes, namely ada/alkA and ogt, was shown to display a hypermutator phenotype. We then looked for polymorphisms in these genes in Central African Republic strains (CAR. Results In this study, 55 MDR and 194 non-MDR strains were analyzed. Variations in DNA repair genes ada/alkA and ogt were identified. Among them, by comparison to M. tuberculosis published sequences, we found a non-sense variation in ada/alkA gene which was also observed in M. bovis AF2122 strain. SNPs that are present in the adjacent regions to the amber variation are different in M. bovis and in M. tuberculosis strain. Conclusion An Amber codon was found in the ada/alkA locus of clustered M. tuberculosis isolates and in M. bovis strain AF2122. This is likely due to convergent evolution because SNP differences between strains are incompatible with horizontal transfer of an entire gene. This suggests that such a variation may confer a selective advantage and be implicated in hypermutator phenotype expression, which in turn contributes to adaptation to environmental changes.

    Full Text Available Facial expressions are widely used in the behavioral interpretation of emotions, cognitive science, and social interactions. In this paper, we present a novel method for fully automatic facial expression recognition in facial image sequences. As the facial expression evolves over time facial landmarks are automatically tracked in consecutive video frames, using displacements based on elastic bunch graph matching displacement estimation. Feature vectors from individual landmarks, as well as pairs of landmarks tracking results are extracted, and normalized, with respect to the first frame in the sequence. The prototypical expression sequence for each class of facial expression is formed, by taking the median of the landmark tracking results from the training facial expression sequences. Multi-class AdaBoost with dynamic time warping similarity distance between the feature vector of input facial expression and prototypical facial expression, is used as a weak classifier to select the subset of discriminative feature vectors. Finally, two methods for facial expression recognition are presented, either by using multi-class AdaBoost with dynamic time warping, or by using support vector machine on the boosted feature vectors. The results on the Cohn-Kanade (CK+ facial expression database show a recognition accuracy of 95.17% and 97.35% using multi-class AdaBoost and support vector machines, respectively.

    We describe a new genus of grylline cricket, Zebragryllus Desutter-Grandcolas & Cadena-Casteñada n. gen., from the Neotropical Region, using characters of morphology and male genitalia; genitalic characters clearly show that Zebragryllus n. gen. is closely related to Anurogryllus Saussure, 1878. Six species are described as new to science, originating from western (Peru, Colombia) and eastern (French Guiana) Amazonia: Zebragryllus fuscus Desutter-Grandcolas, n. sp., Z. guianensis Desutter-Grandcolas, n. sp., Z. intermedius Desutter-Grandcolas, n. sp., Zebragryllus nauta Desutter-Grandcolas, n. sp., Zebragryllus nouragui Desutter-Grandcolas, n. sp., and Zebragryllus wittoto Desutter-Grandcolas and Cadena-Casteñada, n. sp., type species of the genus. They are characterized by their size, coloration (shining black, most often with white patterns of coloration, hence the genus name), and male and female genitalia. The calling songs of Z. guianensis Desutter-Grandcolas, n. sp., Z. intermedius Desutter-Grandcolas, n. sp., Z. nouragui Desutter-Grandcolas, n. sp., and Z. wittoto Desutter-Grandcolas and Cadena-Casteñada, n. sp. are described. An identification key is proposed for both males and females.

    Knowledge of the structural class of a given protein is important for understanding its folding patterns. Although a lot of efforts have been made, it still remains a challenging problem for prediction of protein structural class solely from protein sequences. The feature extraction and classification of proteins are the main problems in prediction. In this research, we extended our earlier work regarding these two aspects. In protein feature extraction, we proposed a scheme by calculating the word frequency and word position from sequences of amino acid, reduced amino acid, and secondary structure. For an accurate classification of the structural class of protein, we developed a novel Multi-Agent Ada-Boost (MA-Ada) method by integrating the features of Multi-Agent system into Ada-Boost algorithm. Extensive experiments were taken to test and compare the proposed method using four benchmark datasets in low homology. The results showed classification accuracies of 88.5%, 96.0%, 88.4%, and 85.5%, respectively, which are much better compared with the existing methods. The source code and dataset are available on request.

    This study reviews and analyzes the content of dental school oaths taken by students in the United States, Canada, and Puerto Rico in 2006. Each oath was qualitatively reviewed to determine its consistency with each of the five principles set forth in the American Dental Association (ADA)'s Principles of Ethics and Code of Professional Conduct. Fifty-eight oaths were received from sixty-one of sixty-six schools in response to information requests regarding use of oaths and manner of administration. Of these, thirty-nine employ one oath, administered at either graduation or ceremonies marking transition to clinical training; twelve employ an oath at both occasions, with five repeating the same oath; and ten have no formal oaths. Eighteen oaths follow the wording of "The Dentist's Pledge," nine follow the "Oath to the Profession/Professional Pledge," three follow the Modern Hippocratic Oath, and twenty-eight are idiosyncratic. All five of the ADA principles (autonomy, nonmaleficence, beneficence, justice, and veracity) are addressed in thirteen oaths, four principles in nine oaths, and three or fewer principles in thirty-six oaths. Eleven make reference to care for the underserved. As oath-taking is an opportunity to instill and reinforce to students dentistry's most important ethical obligations, recommendations are offered to make the content more meaningful and comprehensive.

    血管炎性病变临床表现多样,病因复杂。新近研究发现,部分血管炎性病变可能与猫眼综合征染色体候选基因1(cat eye syndrome chromosome region,candidate 1,CECR1)突变导致CECR1基因编码的腺苷脱氨酶2(adenosine deaminase 2,ADA2)功能缺陷相关。多项研究在结节性多动脉炎和不能明确诊断的血管炎性疾病患者中发现了相同的突变位点,并证实了存在ADA2蛋白功能缺陷。作为腺嘌呤核苷代谢过程中的腺苷脱氨酶(adenosine deaminase,ADA)亚型之一的ADA2不论在早期胚胎发育,还是在特异性免疫系统中都发挥了作用,但目前对于ADA2的功能研究较少。推测ADA2缺陷可能通过增加腺苷水平和破坏血管内皮的完整性从而导致血管炎症的发生,机制尚待进一步研究。总之, ADA2缺陷可能揭示了ADA在人类疾病中的作用,为血管炎性疾病提供了诊断和治疗策略,现对其与血管炎的相关性研究做一综述,以期从遗传学角度探讨血管炎的病因。%The manifestations of vasculitis and vasculopathy are highly varied and have complicated etiology. Recent studies found that part of patients with vasculitis and vasculopathy may be associated with carrying recessively inherited gene mutation inCECR1 (cat eye syndrome chromosome region, candidate 1), encoding adenosine deaminase 2 (ADA2), which resulted in loss of function. The same mutations inCECR1 were found in patients with polyarteritis and vasculitis without being speciifcally deifned in different research, and deifciency of ADA2 was conifrmed. As one of adenosine deaminases (ADA), ADA2 functions in adenosine metabolism, and plays an important role both in early embryonic development and in immune system, but at present there is little study in function of ADA2. It is speculated that ADA2 deifciency induces vasculitis through adenosine increase and destruction of vascular endothelial integrity. The

    AdaBoost算法利用每个特征构造一个简单分类器,然后将简单分类器进行训练组合成一个强分类器.算法能够充分利用每个分类器的优势并避免其劣势,得到一个最佳判别,达到提高分类精度的目的.本文利用TM影像,将影像各波段灰度、水体指数和谱间关系特征相结合,构成提取水体的强分类器,实现水体提取.实验结果表明,算法能够非常有效地、高精度地提取水体信息.%For water body extraction from RS image, previous algorithms have devoted to found a sophisticated classifier based on single feature, which can not make full use of image information and are very difficult to train complex classifier. Adaboost algorithm constructs a simple classifier using each feature, the " strong classifier" is formed after training these simple classifiers. The algorithm can make use of the advantages of the various classifiers and avoid their weaknesses, so it can get a prefer judgment and improve the classification accuracy. In this paper, the strong classifier of extracting body information was constructed after combining spectral information of each band, water index and relationship between spectrums. Using TM imagery as study data, the results of experiment showed that the algorithm could extract water body information effectively and accurately.

    Full Text Available BACKGROUND: Copy number alterations (CNAs in genomic DNA have been associated with complex human diseases, including cancer. One of the most common techniques to detect CNAs is array-based comparative genomic hybridization (aCGH. The availability of aCGH platforms and the need for identification of CNAs has resulted in a wealth of methodological studies. METHODOLOGY/PRINCIPAL FINDINGS: ADaCGH is an R package and a web-based application for the analysis of aCGH data. It implements eight methods for detection of CNAs, gains and losses of genomic DNA, including all of the best performing ones from two recent reviews (CBS, GLAD, CGHseg, HMM. For improved speed, we use parallel computing (via MPI. Additional information (GO terms, PubMed citations, KEGG and Reactome pathways is available for individual genes, and for sets of genes with altered copy numbers. CONCLUSIONS/SIGNIFICANCE: ADACGH represents a qualitative increase in the standards of these types of applications: a all of the best performing algorithms are included, not just one or two; b we do not limit ourselves to providing a thin layer of CGI on top of existing BioConductor packages, but instead carefully use parallelization, examining different schemes, and are able to achieve significant decreases in user waiting time (factors up to 45x; c we have added functionality not currently available in some methods, to adapt to recent recommendations (e.g., merging of segmentation results in wavelet-based and CGHseg algorithms; d we incorporate redundancy, fault-tolerance and checkpointing, which are unique among web-based, parallelized applications; e all of the code is available under open source licenses, allowing to build upon, copy, and adapt our code for other software projects.

    The recruitment of RNA polymerase II on a promoter is assisted by the assembly of basal transcriptional machinery in eukaryotes. The Spt-Ada-Gcn5-Acetyltransferase (SAGA) complex plays an important role in transcription regulation in eukaryotes. However, even in the advent of genome sequencing of various plants, SAGA complex has been poorly defined for their components and roles in plant development and physiological functions. Computational analysis of Arabidopsis thaliana and Oryza sativa genomes for SAGA complex resulted in the identification of 17 to 18 potential candidates for SAGA subunits. We have further classified the SAGA complex based on the conserved domains. Phylogenetic analysis revealed that the SAGA complex proteins are evolutionary conserved between plants, yeast and mammals. Functional annotation showed that they participate not only in chromatin remodeling and gene regulation, but also in different biological processes, which could be indirect and possibly mediated via the regulation of gene expression. The in silico expression analysis of the SAGA components in Arabidopsis and O. sativa clearly indicates that its components have a distinct expression profile at different developmental stages. The co-expression analysis of the SAGA components suggests that many of these subunits co-express at different developmental stages, during hormonal interaction and in response to stress conditions. Quantitative real-time PCR analysis of SAGA component genes further confirmed their expression in different plant tissues and stresses. The expression of representative salt, heat and light inducible genes were affected in mutant lines of SAGA subunits in Arabidopsis. Altogether, the present study reveals expedient evidences of involvement of the SAGA complex in plant gene regulation and stress responses. PMID:26263547

    Patients with adenosine deaminase (ADA) deficiency exhibit spontaneous and partial clinical remission associated with somatic reversion of inherited mutations. We report a child with severe combined immunodeficiency (T-B- SCID) due to ADA deficiency diagnosed at the age of 1 month, whose lymphocyte counts including CD4+ and CD8+ T and NK cells began to improve after several months with normalization of ADA activity in Peripheral blood lymphocytes (PBL), as a result of somatic mosaicism caused by monoallelic reversion of the causative mutation in the ADA gene. He was not eligible for haematopoietic stem cell transplantation (HSCT) or gene therapy (GT); therefore he was placed on enzyme replacement therapy (ERT) with bovine PEG-ADA. The follow-up of metabolic and immunologic responses to ERT included gradual improvement in ADA activity in erythrocytes and transient expansion of most lymphocyte subsets, followed by gradual stabilization of CD4+ and CD8+ T (with naïve phenotype) and NK cells, and sustained expansion of TCRγδ+ T cells. This was accompanied by the disappearance of the revertant T cells as shown by DNA sequencing from PBL. Although the patient's clinical condition improved marginally, he later developed a germinal cell tumour and eventually died at the age of 67 months from sepsis. This case adds to our current knowledge of spontaneous reversion of mutations in ADA deficiency and shows that the effects of the ERT may vary among these patients, suggesting that it could depend on the cell and type in which the somatic mosaicism is established upon reversion.

    Gene transfer into hematopoietic stem cells by gamma-retroviral vectors (RVs) is an effective treatment for inherited blood disorders, although potentially limited by the risk of insertional mutagenesis. We evaluated the genomic impact of RV integration in T lymphocytes from adenosine deaminase-deficient severe combined immunodeficiency (ADA-SCID) patients 10 to 30 months after infusion of autologous, genetically corrected CD34(+) cells. Expression profiling on ex vivo T-cell bulk population revealed no difference with respect to healthy controls. To assess the effect of vector integration on gene expression at the single-cell level, primary T-cell clones were isolated from 2 patients. T-cell clones harbored either 1 (89.8%) or 2 (10.2%) vector copies per cell and displayed partial to full correction of ADA expression, purine metabolism, and T-cell receptor-driven functions. Analysis of RV integration sites indicated a high diversity in T-cell origin, consistently with the polyclonal T-cell receptor-Vbeta repertoire. Quantitative transcript analysis of 120 genes within a 200-kb window around RV integration sites showed modest (2.8- to 5.2-fold) dysregulation of 5.8% genes in 18.6% of the T-cell clones compared with controls. Nonetheless, affected clones maintained a stable phenotype and normal in vitro functions. These results confirm that RV-mediated gene transfer for ADA-SCID is safe, and provide crucial information for the development of future gene therapy protocols. The trials described herein have been registered at http://www.clinicaltrials.gov as #NCT00598481 and #NCT00599781.

  12. Neogene basin development around Söke-Kuşadası (western Anatolia) and its bearing on tectonic development of the Aegean region

    There is a N-S lying narrow strip of Neogene outcrop between the towns of Kuşadası and Söke in western Anatolia. It contains remnants of successive Neogene graben basins. The first graben began to form under the control of a N40-70°E-trending oblique fault system during the Early Miocene. At the initial phase of the opening coarse clastic rocks were deposited in front of the fault-elevated blocks as scree deposits and fanglomerates. Later the graben advanced into a large lake basin. Towards the end of the Middle Miocene the lacustrine sediments of the Early-Middle Miocene age underwent an approximately N-S compressional deformation and elevated above the lake level, and were partly eroded. During the Late Miocene a new graben basin began to form as a consequence of the development of E-W-trending normal faults, formed under the N-S extensional regime. This graben also turned later into a lake environment. The lake extended far beyond the limits of the fault zones, and covered the entire regions stretching from the south of Bafa Lake in the south to Kuşadası and beyond in the north. Micritic clayey limestones were predominantly deposited in the lake. A severe erosional phase followed the termination of the lake basin. This corresponds to the cessation of the N-S extension. When the N-S extension regenerated during the Pliocene(?)-Pleistocene, the Büyük Menderes graben system began to form. In the western part of the graben, a conjugated pair of oblique faults, the Priene-Sazlı fault and the Kuşadası fault, have formed. The faults having important strike-slip components, bounded a tectonic wedge, which began to move westward into the Aegean Sea region. Major morphological features of the region were formed under the effective control of these fault zones.

    2008-07-01

    Full Text Available Abstract Background Recent clinical trials reported conflicting results on the reduction of new-onset diabetes using RAS blocking agents. Therefore the role of these agents in preventing diabetes is still not well defined. Ramipril is an ACE inhibitor (ACEi, that has been shown to reduce cardiovascular events in high risk patients and post-hoc analyses of the HOPE trial have provided evidence for its beneficial action in the prevention of diabetes. Methods The ADaPT investigation ("ACE inhibitor-based versus diuretic-based antihypertensive primary treatment in patients with pre-diabetes" is a 4-year open, prospective, parallel group phase IV study. It compares an antihypertensive treatment regimen based on ramipril versus a treatment based on diuretics or betablockers. The primary evaluation criterion is the first manifestation of type 2 diabetes. The study is conducted in primary care to allow the broadest possible application of its results. The present article provides an outline of the rationale, the design and baseline characteristics of AdaPT and compares these to previous studies including ASCOT-BLPA, VALUE and DREAM. Results Until March 2006 a total of 2,015 patients in 150 general practices (general physicians and internists throughout Germany were enrolled. The average age of patients enrolled was 67.1 ± 10.3 years, with 47% being male and a BMI of 29.9 ± 5.0 kg/m2. Dyslipidemia was present in 56.5%. 37.8% reported a family history of diabetes, 57.8% were previously diagnosed with hypertension (usually long standing. The HbA1c value at baseline was 5.6 %. Compared to the DREAM study patients were older, had more frequently hypertension and patients with cardiovascular disease were not excluded. Conclusion Comparing the ADaPT design and baseline data to previous randomized controlled trial it can be acknowledged that AdaPT included patients with a high risk for diabetes development. Results are expected to be available in 2010. Data

Métodos: comparamos 494 gestantes com mais de 40 anos, com 988 gestantes com idade entre 20 e 29 anos, pareando-as por paridade. Após controlar possíveis variáveis confundidoras pela análise multivariada, a idade materna avançada manteve associação com a maior prevalência de hipertensão arterial, apresentação anômala, parto por cesária, hemorragia puerperal, índice de Apgar baixo, morte perinatal, natimortalidade e sofrimento fetal intraparto. Resultados: a idade materna avançada esteve isoladamente associada à hipertensão arterial, apresentação anômala, diagnóstico de sofrimento fetal intraparto, parto por cesária e hemorragia puerperal. Com relação aos resultados neonatais, a idade materna avançada estava associada independentemente apenas ao baixo índice de Apgar, morte perinatal e óbito fetal. Conclusões: esses achados mostram a necessidade de assistência obstétrica adequada com atenção especial a esses fatores para procurar melhorar os resultados maternos e perinatais das gestantes com idade avançada.Most authors agree on the negative impact of pregnancy in women with advanced maternal age on maternal and perinatal outcome. However, it is not usual to evaluate if some considered risk factors are only confounders because they are present in women over forty years. In order to identify the isolated effect of age on maternal and perinatal outcome of pregnancies in women over forty, 494 pregnancies from this age group were compared to 988 pregnancies among women aged 20 to 29 years, matched by parity. After controlling possible confounding variables through multivariate analysis, advanced maternal age maintained its association with a higher prevalence of hypertension, malpresentation, cesarean section, postpartum hemorrhage, low Apgar score, perinatal death, late fetal

    The authors describe the Ada language software developed to perform the electrical power system monitoring functions for the NASA Lewis Research Center's Power Management and Distribution (PMAD) DC testbed. The results of the effort to implement this monitor are presented. The PMAD DC testbed is a reduced-scale prototype of the electric power system to be used in Space Station Freedom. The power is controlled by smart switches known as power control components (or switchgear). The power control components are currently coordinated by five Compaq 386/20e computers connected through an 802.4 local area network. The power system monitor algorithm comprises several functions, including periodic data acquisition, data smoothing, system performance analysis, and status reporting. Data are collected from the switchgear sensors every 100 ms, then passed through a 2-Hz digital filter. System performance analysis includes power interruption and overcurrent detection. The system monitor required a hardware timer interrupt to activate the data acquisition function. The execution time of the code was optimized by using an assembly language routine. The routine allows direct vectoring of the processor to Ada language procedures that perform periodic control activities.

    Full Text Available OBJECTIVE: Adenosine may play a role in the pathophysiology of schizophrenia, since it modulates the release of several neurotransmitters such as glutamate, dopamine, serotonin and acetylcholine, decreases neuronal activity by pos-synaptic hyperpolarization and inhibits dopaminergic activity. Adenosine deaminase participates in purine metabolism by converting adenosine into inosine. The most frequent functional polymorphism of adenosine deaminase (22G→A (ADA1*2 exhibits 20-30% lower enzymatic activity in individuals with the G/A genotype than individuals with the G/G genotype. The aim of this study was to evaluate the ADA polymorphism 22G→A (ADA1*2 in schizophrenic patients and healthy controls. METHOD: The genotypes of the ADA 22G→A were identified with allele-specific PCR strategy in 152 schizophrenic patients and 111 healthy individuals. RESULTS: A significant decrease in the frequency of the G/A genotype was seen in schizophrenic patients (7/152 - 4.6% relative to controls (13/111 - 11.7%, p = 0.032, OR = 2.6. CONCLUSION: These results suggest that the G/A genotype associated with low adenosine deaminase activity and, supposingly, with higher adenosine levels is less frequent among schizophrenic patients.OBJETIVO: A adenosina pode ter um papel importante na fisiopatologia da esquizofrenia, uma vez que modula a liberação de vários neurotransmissores, tais como glutamato, dopamina, serotonina e acetilcolina, diminui a atividade neuronal por hiperpolarização pós-sináptica e inibe a atividade dopaminérgica. A adenosina desaminase participa do metabolismo das purinas pela conversão de adenosina em inosina. O mais frequente polimorfismo funcional da adenosina desaminase (22G →A (ADA1*2 exibe uma diminuição de 20-30% da atividade funcional em indivíduos com genótipo G/A quando comparados com indivíduos com o genótipo G/G. O objetivo deste estudo foi avaliar o polimorfismo 22G→A (ADA1*2 em pacientes esquizofrênicos e em

    A Olimpíada Brasileira de Astronomia (OBA) contou, em sua quinta edição, com a participação de mais de 60 mil alunos dos ensinos fundamental e médio de praticamente todo o território nacional. Uma das formas de controle que a sua coordenação nacional possui sobre a correção, levada a cabo pelos professores que as aplicaram, é a do envio, por parte destes professores, das 10 melhores provas de cada um dos três níveis nos quais a Olimpíada é realizada. Assim, e dado ao caráter discursivo das provas da Olimpíada, a sua coordenação nacional dispõe de um vasto acervo sobre as concepções, certas ou erradas, dos alunos que dela participaram. Este conjunto de dados jamais fora explorado até o presente trabalho que pretende ser, neste sentido, inaugural. Nas provas dos níveis I e II da V OBA, que abrangem todo o conjunto do ensino fundamental, uma das questões versava sobre a noção que os alunos tinham sobre como os habitantes da Terra situam-se sobre sua superfície. Fizemos um estudo sistemático das respostas a esta questão. Primeiramente, todas as modalidades de erros foram levantadas; em seguida, realizamos uma distribuição por idade tanto do índice de acerto como da ocorrência e da distribuição de cada erro. Como resultado, obtivemos que, em ambos os níveis: 1) as concepções errôneas não se apresentam distribuídas aleatoriamente; 2) há uma concentração no tipo de erro apresentado; 3) há uma tendência de progressivo acerto com relação à idade quando os dados são considerados em termos nacionais; 4) esta tendência nacional é fraca ou mesmo não é verificada em alguns dos estados com maior patamar de acerto.

    Full Text Available Emplazada en la zona de transición sur del segmento de flat-slab pampeano y directamente vinculada a la horizontalización de la placa de Nazca, la faja volcánica terciaria de San Luis delata la migración que experimentó el arco magmático andino a la latitud de los 33º S en tiempos mio-pliocenos. Esta faja volcánica comprende una serie de distritos metalogenéticos de gran importancia en las Sierras Pampeanas de San Luis. Las rocas volcánicas y mineralizaciones de la faja volcánica terciaria se encuentran representadas en los campos volcánicos La Carolina, Cañada Honda - Cerros Largos, Cerros del Rosario y El Morro, dispuestos saltuariamente según una dirección ONO-NO. Las edades K-Ar disponibles indican que el volcanismo se habría iniciado más tempranamente en el sector occidental de esta faja, y que habría finalizado ~ 10 Ma más tarde en la región oriental. El distrito Cañada Honda, el más antiguo y longevo de esta faja volcánica, registra eventos volcánicos e hidrotermales cuyas edades varían entre 12-13 Ma y 7,3 Ma, abarcando facies lávico-hipabisales y volcaniclásticas. Los resultados del análisis estructural demuestran el importante control que, directa o indirectamente, habrían ejercido las estructuras previas en el emplazamiento de las rocas volcánicas y mineralizaciones. Análisis de fábrica deformacional y cinemático han permitido reconocer dos asociaciones volcano-tectónicas diferentes. una de estas asociaciones se vincularía a la reactivación dextral de estructuras paralelas a la foliación del basamento. La asociación principal estaría vinculada con el desarrollo de dos depresiones volcano-tectónicas alineadas en dirección ONO-NO. Sus estructuras principales, de orientación ONO-NO, revelan componentes de desplazamiento senestral y normal tanto a escala del distrito Cañada Honda como de la faja volcánica terciaria.

    Full Text Available Neste trabalho, apresenta-se e se discute um estudo experimental sobre o comportamento estrutural de vigas de concreto reforçadas com bambu. Ensaiaram-se dez vigas de concreto armado, sendo oito vigas armadas longitudinalmente com varas de bambu Dendrocalamus giganteus e duas vigas de referência, armadas com barras de aço. Duas variáveis foram estudadas: a taxa de armadura longitudinal (1,6 e 3,2% e a relação área/perímetro das varas de bambu (0,25 e 0,33 cm. Para cada combinação de variáveis foram confeccionadas duas vigas. Curvas força vs. deslocamento e força vs. deformação dos materiais são apresentadas e discutidas. Constatou-se que o comportamento estrutural das vigas de concreto reforçadas com bambu segue a teoria de flexão de Bernoulli-Kirchoff, sendo possível a aplicação dos procedimentos usuais de dimensionamento do concreto armado no projeto desses elementos. Observou-se, também, que a capacidade de carga dessas vigas se assemelha à das vigas de aço; contudo, estas são mais rígidas que aquelas.In this paper, an experimental study about bamboo reinforced concrete beams is presented and discussed. Ten reinforced concrete beams were tested, where eight of them were reinforced with Dendrocalamus giganteus bamboo-splint and two reference beams were reinforced with steel bars. Two factors were studied: the longitudinal reinforcement ratio (1.6 and 3.2% and the area/perimeter ratio of the bamboo-splint (0.25 and 0.33 cm. For each factor combination, two beams were cast. Force vs. displacement and force vs. strain curves are presented and discussed. It was found out that the structural behaviour of bamboo-concrete beams follow the Bernoulli-Kirchoff bending theory. Therefore, the usual design procedures of reinforced concrete can be used to design the bamboo-concrete beams. The load capacity of the bamboo-concrete beams is almost the same as that of reinforced with steel; nevertheless, are more stiffer than those

    Most areas planted with sugarcane are located in southern China. However, remote sensing of sugarcane has been limited because useable remote sensing data are limited due to the cloudy climate of this region during the growing season and severe spectral mixing with other crops. In this study, we developed a methodology for automatically mapping sugarcane over large areas using time-series middle-resolution remote sensing data. For this purpose, two major techniques were used, the object-oriented method (OOM) and data mining (DM). In addition, time-series Chinese HJ-1 CCD images were obtained during the sugarcane growing period. Image objects were generated using a multi-resolution segmentation algorithm, and DM was implemented using the AdaBoost algorithm, which generated the prediction model. The prediction model was applied to the HJ-1 CCD time-series image objects, and then a map of the sugarcane planting area was produced. The classification accuracy was evaluated using independent field survey sampling points. The confusion matrix analysis showed that the overall classification accuracy reached 93.6% and that the Kappa coefficient was 0.85. Thus, the results showed that this method is feasible, efficient, and applicable for extrapolating the classification of other crops in large areas where the application of high-resolution remote sensing data is impractical due to financial considerations or because qualified images are limited.

    Full Text Available O presente artigo tem por objetivo apresentar alguns dos aspectos mitológicos que fundamentam a realização das olimpíadas desde a antiguidade grega, particularmente a “corrida de tochas acessas” que atualmente inaugura a abertura dos jogos. Para tanto, buscamos apresentar alguns relatos que narram a realização dos jogos olímpicos como uma espécie memória aos mitos fundadores da cultura grega. Nesse registro, consideramos alguns aspectos das narrativas de Hesíodo sobre o mito de Prometeu, bem como algumas observações de filósofos modernos como Francis Bacon e Thomas Hobbes sobre como essa fábula narra a interpretação de uma condição humana fundada em uma competição análoga à uma interminável luta de titãs. Condição humana essa oriunda da desobediência às vontades dos deuses do Olimpo, cristalizada na expressão de uma cultura da competição que visa não apenas agradar a esses deuses, detentores do poder no Olimpo, mas também igualar certos homens a eles.

    The Upper Jurassic Tordillo Formation at Cañada Ancha area, northern Neuquén Basin, Argentina, comprises a multi-stage suit of predominantly alluvial sediments that is heterolithic in nature. In that suit, several lithofacies, architectural elements, and bounding surfaces of different order have been identified and their lateral and vertical distribution characterized. This analysis allowed the differentiation of 3 main units (lower, middle and upper), 20 subunits (C-1 to C-20), and the characterization of their alluvial styles. The lower unit (which comprises subunits C-1 to C-4) is mainly formed by fine- to medium-grained sandstones, which become medium- to coarse-grained towards the top. These sandstones characterize settings ranging from floodplains with isolated, unconfined flows, to more complex, vertically stacked, multi-storey sheet sandstones of braided fluvial systems. The middle unit (C-5 to C-10) is dominated by pale brown-grey fine-to coarse-grained sands and medium size subangular to angular conglomerates, which reflect amalgamated complexes of sandstone sheets and downstream accretion macroforms. Remarkably, this alluvial sedimentation was episodically punctuated by volcaniclastic flows. The upper unit (C-11 to C-20) consists of finer sediments, mainly pink to white fine-to medium grained sandstones and red to green siltstones. Towards the top, bioturbation becomes important, and also the presence of volcanosedimentary flows is noticeable. Fluvial settings include braided sheet sandstones with waning flood deposits evolving to isolated high-sinuosity fluvial systems, with flash flood deposits. At the top of this unit, facies may suggest marine influence. Vertical changes in the fluvial style result from both climatic and tectonic controls. A semiarid to arid climate and the active tectonism linked to the eastward migration of the Andean volcanic arc determined major bounding surfaces, fluvial style evolution and the presence of the volcano

    Full Text Available A geração dos produtos de glicação avançada é um dos principais mecanismos desencadeadores das doenças associadas ao diabetes mellitus, que incluem cardiopatia, retinopatia, neuropatia e nefropatia. Esta revisão tem como objetivo analisar o papel dos produtos de glicação avançada presentes na alimentação como mediadores das complicações diabéticas e apresentar estratégias de redução de sua ingestão. Para tanto, foram realizados levantamentos em bancos de dados de publicações da área, dos últimos 15 anos, considerando-se artigos de revisão, estudos clínicos e experimentais. Os produtos de glicação avançada são um grupo heterogêneo de moléculas formadas a partir de reações não enzimáticas entre grupamentos amino e carbonilo, sendo a carboximetilisina e a pentosidina exemplos de produtos de glicação avançada identificados em alimentos e in vivo. Os produtos de glicação avançada ingeridos são absorvidos, somando-se aos endógenos no surgimento e na progressão das diversas complicações do diabetes, existindo uma correlação direta entre o consumo e a concentração sanguínea. Sua restrição na alimentação se correlaciona à supressão dos níveis séricos de marcadores de doença vascular e de mediadores inflamatórios diretamente envolvidos no desenvolvimento das degenerações diabéticas. As atuais orientações dietéticas centram-se na proporção em nutrientes e na restrição energética, sem considerar o risco da ingestão de produtos de glicação avançada formados durante o processamento dos alimentos. Recomendações simples, como a utilização de temperaturas baixas por períodos mais curtos, em presença de água, no preparo de alimentos, exercem efeitos importantes na prevenção das complicações do diabetes. O estudo dos mecanismos envolvidos na geração de produtos de glicação avançada e das propriedades anti-glicação de compostos presentes nos alimentos podem contribuir com

    Full Text Available Roofing provides the main protection against direct solar radiation in animal housing. Appropriate thermal properties of roofing materials tend to improve the thermal comfort in the inner ambient. Nonasbestos fiber-cement roofing components reinforced with cellulose pulp from sisal (Agave sisalana were produced by slurry and dewatering techniques, with an optional addition of polypropylene fibers. Nonasbestos tiles were evaluated and compared with commercially available asbestos-cement sheets and ceramic tiles (frequently chosen as roofing materials for animal housing. Thermal conductivity and thermal diffusivity of tiles were determined by the parallel hot-wire method, along with the evaluation of the downside surface temperature. Cement-based components reinforced with sisal pulp presented better thermal performance at room temperature (25ºC, while those reinforced with sisal pulp added by polypropylene fibers presented better thermal performance at 60ºC. Non-asbestos cement tiles provided more efficient protection against radiation than asbestos corrugated sheets.O telhado fornece a principal proteção contra a radiação solar direta em galpões para animais.

    A path to new synthons for application in crystal engineering is the replacement of a strong hydrogen-bond acceptor, like a C=O group, with a weaker acceptor, like a C=S group, in doubly or triply hydrogen-bonded synthons. For instance, if the C=O group at the 2-position of barbituric acid is changed into a C=S group, 2-thiobarbituric acid is obtained. Each of the compounds comprises two ADA hydrogen-bonding sites (D = donor and A = acceptor). We report the results of cocrystallization experiments of barbituric acid and 2-thiobarbituric acid, respectively, with 2,4-diaminopyrimidine, which contains a complementary DAD hydrogen-bonding site and is therefore capable of forming an ADA/DAD synthon with barbituric acid and 2-thiobarbituric acid. In addition, pure 2,4-diaminopyrimidine was crystallized in order to study its preferred hydrogen-bonding motifs. The experiments yielded one ansolvate of 2,4-diaminopyrimidine (pyrimidine-2,4-diamine, DAPY), C4H6N4, (I), three solvates of DAPY, namely 2,4-diaminopyrimidine-1,4-dioxane (2/1), 2C4H6N4·C4H8O2, (II), 2,4-diaminopyrimidine-N,N-dimethylacetamide (1/1), C4H6N4·C4H9NO, (III), and 2,4-diaminopyrimidine-1-methylpyrrolidin-2-one (1/1), C4H6N4·C5H9NO, (IV), one salt of barbituric acid, viz. 2,4-diaminopyrimidinium barbiturate (barbiturate is 2,4,6-trioxopyrimidin-5-ide), C4H7N4(+)·C4H3N2O3(-), (V), and two solvated salts of 2-thiobarbituric acid, viz. 2,4-diaminopyrimidinium 2-thiobarbiturate-N,N-dimethylformamide (1/2) (2-thiobarbiturate is 4,6-dioxo-2-sulfanylidenepyrimidin-5-ide), C4H7N4(+)·C4H3N2O2S(-)·2C3H7NO, (VI), and 2,4-diaminopyrimidinium 2-thiobarbiturate-N,N-dimethylacetamide (1/2), C4H7N4(+)·C4H3N2O2S(-)·2C4H9NO, (VII).

    Full Text Available A deficiência transversa da maxila é um fator agravante e complicador do tratamento ortodôntico em adultos. Sua correção ainda gera dúvidas e controvérsias entre clínicos e pesquisadores. O objetivo deste trabalho foi analisar e discutir fatores determinantes para o planejamento da expansão maxilar em adultos e adolescentes com maturação esquelética avançada. Ausências dentárias múltiplas, grandes inclinações dentoalveolares para vestibular, recessão gengival, perda óssea alveolar e mobilidade dos dentes posterossuperiores contraindicam a realização de expansão rápida da maxila em indivíduos adultos ou com maturação esquelética avançada. No entanto, esses fatores não devem ser considerados isoladamente para a escolha do método de expansão palatal nesses pacientes. Nessas situações, a Expansão Rápida da Maxila Assistida Cirurgicamente (ERMAC pode ser uma opção, entretanto, a escolha por essa técnica deve basear-se principalmente na idade do paciente, no grau de maturação esquelética, na localização da deficiência transversa da maxila e nas estruturas anatômicas que oferecem maior resistência à expansão maxilar. O Hyrax é o aparelho mais indicado para indivíduos que vão se submeter à ERMAC.The transverse maxillary deficiency is a complication factor in adults' orthodontic treatment. Its correction still generates doubts and controversies between clinicians and researchers. The aim of this paper is to discuss the determinative factors in planning maxillary expansion in adults and adolescents with advanced skeletal maturation. Multiple dental absences, several dentoalveolar buccal inclination, gingival recession, alveolar bone loss and mobility of posterosuperior teeth contraindicate the rapid maxillary expansion in adults or patients with advanced skeletal maturation. However, these factors should not be considered separately when choosing the method for palatal expansion in adults. In these

MÉTODOS: Equações e limites de referência foram derivados em 270 homens e 373 mulheres, habitantes de oito cidades brasileiras, por espirômetro. A idade variou de 20 a 85 anos nas mulheres e 26 a 86 anos nos homens. Os exames seguiram as normas recomendadas pela Sociedade Brasileira de Pneumologia e Tisiologia. Os limites inferiores foram derivados pela análise do 5º percentil dos resíduos. RESULTADOS: Os valores previstos para capacidade vital forçada (CVF, volume expiratório forçado no primeiro segundo (VEF1 e para as relações VEF1/CVF e VEF1/volume expiratório forçado nos primeiros seis segundos (VEF6 se ajustaram melhor em regressões lineares. Os fluxos ajustaram-se melhor em equações logarítmicas. Em ambos os sexos, maiores estaturas resultaram em menores valores para as relações VEF1/CVF, VEF1/VEF6 e fluxos/CVF. Os valores de referência do VEF1 e da CVF, no presente estudo, foram maiores do que aqueles derivados para adultos brasileiros em 1992. CONCLUSÃO: Novos valores previstos para a espirometria forçada foram obtidos em uma amostra da população brasileira de raça branca.

Superando el uso metafórico del concepto de red social, se adopta en esta investigación la metodología del Análisis de Redes Sociales (ARS para estudiar las redes personales tejidas durante las dos últimas décadas del siglo XVIII por los agentes sociales detentores de mayor capital social en la parroquia eclesiástica Inmaculada Concepción de La Cañada, provincia de Maracaibo de la antigua Capitanía General de Venezuela, me-diante vínculos de parentesco consanguíneo y vínculos derivados de las instituciones eclesiásticas del matrimonio y el bautismo. La utilización de la metodología del ARS permitió ilustrar un enfoque todavía muy poco utilizado en la investigación histórica, y profundizar en aspectos de interés relativos a la creación de vínculos personales, la distribución del capital social y las estrategias de reproducción social puestas en práctica por los habitantes de una comunidad rural de la América Hispana.

It compares information content of PP 24/2005’s cash toward accrual and PP 71/2010’s accrual-based toshow the urgency of accrual-based financial reporting requirements. The analysis borrows Abeysekara’s accounting imperialism. Discussion also involves empirical evidence and evaluation of accrual-based implementation probability in Sumenep Regency. Findings show that accrual-based information is not an urgent need and tends to be difficult to be implemented. Reflecting the evidence in Sumenep, local governments are faced with the need of human resources, the question of the use-fulness of accrual information, and technical difficulties on implementation.

No presenta aún desarrollo de condromas pulmonares visibles por tomografía axial computada. En nuestra paciente el paraganglioma no resultó funcionante. Resaltamos que la presencia de tumores gástricos múltiples en un adulto joven debe sugerir la posibilidad de tumores estromales (GIST, cuyo diagnóstico por biopsia endoscópica es difícil debido a su localización profunda, situada en las capas musculares de la pared gástrica. Asimismo queremos remarcar la importancia de las técnicas de marcación descriptas para el diagnóstico preciso. El seguimiento debe ser constante dado el pronóstico incierto de estos tumores. Los condromas pulmonares pueden aparecer años después de la resección del GIST y ser confundidos con metástasis del GIST.The case of young woman with arterial hypertension diagnosed two years before, is here presented; she had a ferropenic anemia caused by digestive loss of blood. Multiple gastric tumors and pararenal non functioning paraganglioma were found. No chondromas were detected. An incomplete Carney’s Triad was diagnosed. We remark that multiple gastric tumors in a young adult suggest the possibility of gastrointestinal stromal tumors (GIST Endoscopic biopsy frequently is not effective because these tumors are deep placed in the muscular gastric layers. The importance of specific techniques for a positive diagnosis are emphasized. Continuous follow up is needed because these tumors have uncertain prognosis. Lung chondromas may appear years later after the GIST was removed and might be confused with GIST metastases.

    Full Text Available A busca por materiais alternativos que possam substituir as fibras de amianto, compondo o fibrocimento, tem-se tornado objeto de estudos recorrentes. As fibras vegetais surgem como opção econômica, salubre e ecologicamente adequada. O objetivo desse trabalho foi estudar o comportamento da adição da fibra de curauá em compósitos cimentícios, visando a substituir o amianto. Essa fibra mineral é bastante conhecida pelos danos que provoca à saúde humana, já tendo sido banida em muitos países industrializados. Desde 1979, o Grupo de Pesquisas em Materiais não Convencionais da PUC-Rio tem desenvolvido trabalhos sobre a aplicação das fibras vegetais, disponíveis em abundância no Brasil, na fabricação de componentes para a construção civil, visando, principalmente, à produção de habitação popular. A fibra de curauá é de uso popular, na região conhecida como Baixo-Amazonas, oeste do Estado do Pará, na manufatura de cordas, cestas e tapetes, já existindo os primeiros plantios em escala comercial. Pouco conhecida nas demais regiões do país, a fibra de curauá ainda carece de estudos específicos sobre suas propriedades físicas, químicas e mecânicas, que possibilitem sua aplicação segura em compósitos para a construção civil. Nesse artigo, foi estudado o comportamento em compressão de argamassas reforçadas com fibras de curauá. Buscou-se comparar o desempenho das fibras de curauá e de seus compósitos, com as fibras e compósitos de amianto e de outras fibras vegetais, tais como sisal e juta. Para os compósitos cimentícios com reforços de juta e de sisal, foram obtidos dados através de ensaios realizados no escopo desse trabalho. Os resultados mostraram que a fibra de curauá possui características físicas e mecânicas que a habilitam à aplicação como reforço de matrizes cimentícias, principalmente quando for almejada uma maior ductilidade e uma maior capacidade de resistência após a fissuração da

    , considerando la realidad político económica actual y el sistema de servicios de salud en Portugal.OBJETIVO: este artigo foca o contexto político da implementação de competências avançadas em enfermagem, com ênfase no caso português. O setor da saúde em Portugal, assim como em outros países, usa mão de obra intensa, e a prática de enfermeiros com competências avançadas está atualmente em debate. MÉTODOS: abordagem de métodos mistos com análise de dados internacionais sobre a mão de obra em enfermagem, documentos e notícias na mídia, entrevistas com informantes-chave, questionário online e um workshop técnico com informantes-chave. CONCLUSÕES: existe base de evidência limitada sobre enfermeiros com funções avançadas em Portugal, o que é um entrave ao progresso, mas não uma desculpa para a inércia. Mais estudos conduzidos em Portugal, abordando funções inovadoras para profissionais da saúde, ajudariam a informar e direcionar políticas na área. É necessário avançar para informar, de forma plena, o diálogo político, levando em consideração a realidade atual em termos políticos, econômicos e do sistema de saúde em Portugal.

O caso aqui apresentado é uma abordagem interdisciplinar entre ortodontia e periodontia, em que uma paciente com doença periodontal avançada foi tratada pela técnica de erupção ortodôntica forçada e teve, ao final do tratamento, sua reabilitação conseguida com crescimento ósseo e gengival num primeiro instante e colocação de implantes e próteses dentárias numa abordagem também inovadora de carregamento protético imediato, ou seja, implantes e dentes colocados com 48 horas de diferença. O resultado alcançado aponta que nossos estudos devem prosseguir, visto que o crescimento ósseo foi conseguido sem a necessidade de enxerto, o tempo do tratamento não superou os 120 dias e que no futuro devemos obter resultados que colaborem para a superação de doenças periodontais graves sem varias etapas cirúrgicas, diminuindo o tempo de tratamento, morbidade e custos para o paciente.In this case report we discuss the importance of panoramic x-ray as an auxiliary tool for the diagnosis, initial treatment and follow-up of patients with periodontal disease. The case presented involved an interdisciplinary approach between orthodontics and periodontics. A female patient with advanced periodontal disease was treated with the forced orthodontical eruption technique that resulted in bone and gingival growth at the end of the treatment. Placement of the implants and dental prostheses was also performed in an innovative approach of immediate prosthetic loading, i.e. implants and teeth placed within a 48 hours interval. These results indicate that our studies should continue since bone growth was obtained without a bone graft, the time of the treatment did not exceed 120 days, and that we may in future obtain further results that will contribute to

Para validá-lo, aplicou-se o escore num grupo de 95 pacientes com idade inferior a 65 anos, sem evidências de doenças consumptivas e analisou-se se esse escore manteria correlação com os dados clínicos da IC e permitiria estratificar o prognóstico. RESULTADOS: A situação nutricional esteve alterada nos pacientes e escore elevado sugerindo desnutrição moderada ou intensa foi observado em 31/95 (32,6% dos casos. Não houve correlação entre os valores do escore nutricional, duração dos sintomas e grau de disfunção ventricular. Os pacientes com escore nutricional elevado apresentaram tendência de maior mortalidade (p=0,0606. CONCLUSÕES: Os dados sugerem que a desnutrição atinge cerca de 1/3 dos pacientes com IC avançada. Um escore que englobou cinco parâmetros de avaliação nutricional teve boa correlação com a avaliação clínica e permitiu avaliar globalmente a desnutrição de portadores de IC.

Geralmente esta lesão estava associada a sinais de hipertensão porta (esplenomegalia e varizes do esôfago, constitutindo-se na forma hépato-esplênica mas em 12 casos estes sinais não existiam (a forma hepática avançada. Ao passar para a fase descompensada da esquistossomose hépato-esplênica, o fígado geralmente exibia uma acentuação da fibrose ao lado de sinais de inflamação crônica ativa, mas não mostrava uma evolução para a cirrose difusa. A esplenomegalia se acompanhou de lesões congestivas crônicas e de evidências de hiperplasia celular, especialmente no setor fagocítico mononucelar. Excepecionalmente se superajuntou a tais lesões um linfoma tipo nodular, o qual tende a ocorrer em mulheres após os 45 anos de idade. O envolvimento intestinal foi muito menor do que se poderia esperar. As lesões mais salientes foram a fibrose peri-intestinal, qua não parece ter maior repercussão clínica, e, raramente, as lesões pseudoneoplásicas e os polipos. Uma complicação freqüente foi o cor pulmonale secundário às elsões de arterite pulmonar esquistossomótica, que apareceu em 44 casos (18,9%. O aparecimento de doença renal associada se deu em 15% dos casos e foi geralmente representada por glomerulonefrite crônica, o que se presume seja devido a um processo mediado por complexos imunes na esquistossomose. Muitos dos casos exibiam infecções intercorrentes, com algumas delas, como a salmonelose e a hepatite viral, tendendo a ter um curso mais prolongado. Assim a esquistossomose avançada se apresentou um processo que atinge fundamentalmente of fígado, mas que repercute em vários outros órgãos através uma patogenia variada, complexa, ainda não bem

    Full Text Available In this article, the writer discusses the prevalence of politics in organisations from the perspective of human resource management. There are some reasons as to why political issues always present in organisational matters: unclear formulation of objectives, resources scarcity, changes in technology and environment, un-programmed decisions, and organisational development. Hence, political behaviours would have significant impacts on the practice of human resources development. It is identified that political behaviours would influence performance assessment and evaluation, remuneration and compensation, and career or promotions. To create a more effective organisation and ascertain that it would attain its goals, there is a need for specific managerial approach which would able to overcome negative aspects of political behaviours.

    Full Text Available Desde la arquitectura no solo se construyen lugares con acero, madera, hormigón o cristal, sino también con la acción y la mirada. A través de derivas realizadas en distintas ciudades se establecen diferentes maneras de percibir la realidad urbana, maneras que a menudo quedan sepultadas bajo las representaciones dominantes de la ciudad. Construir documentos que muestren la ciudad desde ópticas tangenciales, relacionadas con visiones subjetivas y vivencias concretas, va más allá de un mero ejercicio de representación. Los mapas de derivas urbanas expuestos en este artículo ponen de manifiesto relaciones intensas con la ciudad a través de la acción que resultan en nuevas visiones urbanas. Nuevas maneras de percibir la ciudad abren caminos a nuevos modos de entender la rica realidad urbana, que a su vez inauguran nuevos modos de transformarla desde el proyecto arquitectónico. El sentido último de las derivas presentadas es la de abrirse a la riqueza de la ciudad para descubrir en ella múltiples niveles de sentido que sugieren nuevas maneras de transformar la ciudad

    2002-07-01

    Full Text Available Dental amalgam is one of the oldest restorative materials, used in dentistry, which has undergone a lot of quality changes since its advent. Copper is one of the major elements in dental amalgam. Dental amalgam is classified as low and high cooper group based on the percentage of this element. Cinaluy is an Iranian product, a product of Shahid Faghihi's factory and its particles are spherical with high copper and it does not contain any zinc and gama II phase. The goal of this study was to identify the type and percentage of its ingredients and to analyze this dental amalgam by muclear reactor. The products of the factory, at two different times, were compared with each other and also with the percentages presented by the factory, regarding their ingredients. They were also compared with two standardized amalgams called: Sybralloy and Tytin. Three typical Cinalux amalgam capsules, produced on different dates, were selected. The contents of capsules were enveloped in plastic bags and then sealed and placed in a miniature reactor to undergo nuclear radiation for 10 days. After this period, the elements in amalgam became activated and converted into radioisotopes of the same elements, and began to radiate. Then gama spectrometer system accumulated these radiations and transferred them to Span software. This software, aided by reference standards, shows the intensity and the wave length of the received radiation, and consequently identifies the type and percentage of the elements in amalgam. The results demonstrated that the Cinalux amalgam samples, regarding the type and percentage of their elements, were identical and also met the factory standards. The differences were not significant. There was also no significant difference between Cinalux amalgam and the standardized amalgam Sybralloy, regarding the percentage of their elements, but comparing this amalgam with the standardized amalgam Tytin, a significant difference was not observed.

    Full Text Available Requerendo apenas cooperação passiva e fornecendo novos parâmetros para análise da mecânica ventilatória, a técnica de oscilações forçadas (TOF apresenta características complementares aos métodos clássicos de avaliação pulmonar. Neste trabalho, inicialmente é apresentada uma revisão dos princípios da técnica juntamente com uma discussão sobre suas vantagens e atuais limitações. A performance da técnica é comparada com a dos métodos clássicos na detecção de afecções respiratórias. As principais aplicações clínicas reportadas anteriormente na literatura, incluindo a avaliação da mecânica ventilatória infantil, estudos em neonatos, monitorização de pacientes sob ventilação mecânica, medicina ocupacional e avaliação de distúrbios no sono, são revisadas e discutidas. Com base na revisão efetuada e nos resultados obtidos em estudos efetuados em laboratório, os autores concluem que a TOF pode contribuir para um exame mais detalhado, assim como para facilitar a realização de testes de função pulmonar em condições nas quais as técnicas tradicionais não são adequadas.Requesting passive cooperation from the patient and supplying new parameters for the analysis of the ventilatory mechanics, the forced oscillations technique (FOT has complementary characteristics to the classical methods of lung evaluation.

    Full Text Available O objetivo do presente estudo foi avaliar o comportamento de variáveis fisiológicas durante uma sessão de treino de nado sincronizado realizada na fase de preparação para as Olimpíadas de Atenas 2004. MATERIAIS E MÉTODOS: A amostra utilizada foi constituída pelo dueto (24 ± 0 anos representante do Brasil em Atenas 2004. A coleta de dados foi realizada durante uma sessão de treinamento com duração de 198 minutos. O treino se iniciou com a parte física, seguida da parte técnica. Para a determinação da glicemia e da concentração de beta-hidroxibutirato foi utilizado o monitor Optium® com suas respectivas tiras. As concentrações de cortisol e das enzimas lactato desidrogenase (LDH e creatina quinase (CK foram determinadas por radioimunoensaio (DPC© e kits comerciais (CELM®, respectivamente. O acompanhamento da freqüência cardíaca (FC foi realizado com o freqüêncimetro Advantage Polar®. RESULTADOS: Foi observada redução (~2% do peso corporal. A glicemia também apresentou queda (~30% em comparação ao valor obtido no início do treino. Em contrapartida, foi observada elevação na concentração de cortisol (salivar 22% e plasmática 29% e de beta-hidroxibutirato (~340%. Não foi observada alteração significativa na concentração plasmática de CK e de LDH. O acompanhamento da FC demonstrou que dos 198 minutos que constituíram a sessão de treino, 36,5 ± 0,7 minutos foram realizados em intensidade leve; 103,5 ± 0,7 minutos em intensidade moderada, 54,0 ± 2,1 minutos em intensidade alta e 4,0 ± 0,0 minutos em intensidade muito alta. CONCLUSÕES: A perda de peso indica que a reposição hídrica não foi adequada. A redução na glicemia e o aumento na concentração de corpos cetônicos e de cortisol reforçam a importância da suplementação de carboidrato durante o treino de longa duração. O comportamento da FC demonstra que a sessão de treinamento foi realizada em uma intensidade moderada, porém com

    Full Text Available Para garantir a qualidade das informações disponibilizadas pelas empresas brasileiras, o legislador e os órgãos de regulamentação têm empreendido esforços no sentido de definir as informações que devem ser apresentadas nas demonstrações contábeis. Entretanto, nem todas as orientações têm caráter de obrigatoriedade, tornando-se mais uma questão de ética e responsabilidade corporativa. O presente estudo procura responder à seguinte questão de pesquisa: Qual o grau de observância às orientações sobre evidenciação contábil praticado pelas sociedades anônimas brasileiras no tocante à prestação de informações não contempladas nas demonstrações contábeis tradicionais, consideradas de natureza avançada e não obrigatória? O estudo analisou as demonstrações contábeis de 95 empresas, relativas ao exercício social encerrado em 31/12/2002, com a utilização do método de "análise de conteúdo". Utilizou-se o software Statistical Package for Social Sciences - SPSS para apoio na tabulação e análise dos dados. De um total de 21 itens de evidenciação investigados, apenas seis apresentaram um índice de observância superior a 50%, o que demonstra que as organizações ainda têm um longo caminho a percorrer na busca da transparência e qualidade na divulgação das informações contábeis.In order to ensure the quality of information issued by Brazilian enterprises, legislators and regulatory agencies are making efforts to determine the set of information that should appear in the financial statements. However, not all of their recommendations are obligatory, turning this into a matter of company ethics and corporate responsibility. In this paper, the authors attempt to answer the following question: To what extent do Brazilian corporations follow the recommendations on advanced and non-obligatory information disclosure, which is not considered in traditional financial statements.

    Full Text Available Objetivou-se com este trabalho avaliar o efeito de diferentes teores de fibra em detergente neutro oriunda da forragem com maturidade avançada sobre o consumo, a digestibilidade da matéria seca e de nutrientes, o balanço de nitrogênio, a produção de leite, a eficiência de utilização da energia metabolizável e o comportamento ingestivo de cabras em lactação. Foram distribuídas cinco cabras em delineamento em quadrado latino 5 × 5 utilizando-se teores crescentes de fibra em detergente neutro oriunda da forragem como variável independente. As concentrações de fibra em detergente neutro oriunda da foragem utilizadas foram 20, 28, 35, 43 e 49%. Os consumos de matéria seca, de nutrientes e de energia líquida reduziram com o aumento de fibra na ração. No entanto, o consumo de fibra em detergente foi crescente, indicando capacidade de acomodação desse componente nutritivo pelos animais. O teor de fibra influenciou os coeficientes de digestibilidade da matéria seca, matéria orgânica, proteína bruta e dos carboidratos não-fibrosos, contudo, a digestibilidade da fibra em detergente neutro não foi influenciada pelas dietas. O nível de fibra em detergente neutro oriunda da forragem não influenciou os constituintes do leite (gordura, proteína e lactose. O teor de fibra oriunda da forragem teve efeito quadrático sobre a produção de leite (corrigida e não corrigida para 4% de gordura, em kg/dia, com maiores produções obtidas com o teor de 28% de fibra. A eficiência de utilização da energia metabolizável não foi influenciada pelas variações nas dietas. O teor de fibra em detergente neutro oriunda da forragem influencia o comportamento ingestivo de cabras em lactação, aumentando os tempos de ruminação e mastigação e diminuindo o tempo em ócio dos animais.The objective of this study was to evaluate the different contents of neutral detergent fiber from forage at advanced maturity on intake, digestibility of the

MÉTODOS: noventa e três mulheres com diagnóstico de infertilidade, com ciclo menstrual normal, não submetidas a qualquer tratamento hormonal e cirúrgico durante o último ano, índice de massa corporal igual a 20-25, portadoras de ovários sem a presença de cistos ou tumores participaram deste estudo e foram divididas em dois grupos: tubário (TUB, 39 mulheres com ligadura tubária, e endometriose (EDT, 54 mulheres com EDT-III e EDT-IV, submetidas a indução ovulatória com FSH-r e ICSI. Os dados clínicos e laboratoriais foram comparados. Testes chi2, Fisher, t pareado, t de Student e Mann-Whitney foram empregados. RESULTADOS: níveis mais baixos de estradiol (2243,1 vs 1666,3; p=0,001 e número menor de folículos por paciente (16,9 vs 13,9; p=0,001 foram recuperados no grupo EDT, apesar da utilização de maior número de unidades de FSH-r (1775,6 vs 1998,6; p=0,007, para TUB e EDT, respectivamente. Não houve diferença quanto à taxa de recuperação ovocitária (69 vs 73,5%; p=0,071 assim como nas taxas de fertilização normal (83,7 vs 81,7%; p=0,563 respectivamente para TUB e EDT. No entanto, menor número de pré-embriões ótimos foi obtido no grupo EDT (36,4 vs 24,8%, respectivamente para TUB e EDT; p=0,005. As taxas de gestação total (41,0 vs 42,6%; p=0,950 e de implantação (13,9% x 14,5%; p=0,905 não foram significativamente diferentes quando TUB e EDT foram comparados. CONCLUSÕES: os ovários das mulheres do grupo EDT parecem ser menos responsivos à indução da ovulação com FSH-r.

    Full Text Available The objective of this study was to evaluate the tensile (sigmat and shear bond strength (sigmas of a glass-infiltrated alumina-based zirconia-reinforced ceramic (IZ - Vita In-Ceram Zirconia to a composite resin, testing the hypothesis that silica coating (SC - Cojet, 3M-Espe produces higher bond strength values than other ceramic surface treatments. Specimens were fabricated and tested according to the manufacturers' instructions, and to ISO6872 and ISO11405 specifications. Sixty IZ disk specimens were polished through 1 µm and divided into 3 groups (n = 20 according to the following surface treatments: HF - 9.5% hydrofluoric acid (Ultradent for 1 min; SB - sandblasting with 25-µm aluminum oxide particles for 10 s; SC - silica coating for 10 s. Silane (3M-Espe, adhesive (Single Bond, 3M-Espe and a composite resin cylinder (Z100, 3M-Espe were applied and polymerized to the treated bonding area (3.5 mm in diameter. Ten specimens from each group (n = 10 were tested for sigmat and ten specimens were tested for sigmas, using a universal testing machine (EMIC DL 2000 at a crosshead speed of 1 mm/min. The data were statistically analyzed by ANOVA and Tukey tests (alpha = 0.05. The mean and standard deviation values (MPa and statistical groupings for sigmat were: HF - 3.5 ± 1.0a; SB - 7.6 ± 1.2b; and SC - 10.4 ± 1.8c. For sigmas, the values were: HF - 10.4 ± 3.1A; SB - 13.9 ± 3.1B; and SC - 21.6 ± 1.7C (p O objetivo deste estudo foi avaliar a resistência adesiva à tração (sigmat e ao cisalhamento (sigmas de uma cerâmica à base de alumina infiltrada por vidro e reforçada com zircônia (IZ- Vita In-Ceram Zircônia à resina composta, testando a hipótese de que o sistema de silicatização (SC- Cojet, 3M-ESPE produz valores maiores de resistência adesiva do que demais tratamentos de superfície utilizados.

    Full Text Available Foram realizados três experimentos com 336 poedeiras no segundo ciclo de produção e 24 meses de idade, alojadas em condições de criação comercial (550 cm²/ave. O objetivo foi avaliar o alho (5 kg/t, probiótico (300 g/t e a virginiamicina (20 g/t como aditivos de rações antes, durante e após o estresse induzido pela muda forçada (MF. O delineamento experimental foi o inteiramente ao acaso e os tratamentos usados foram: dieta controle (DC; DC+alho (A; DC+probiótico (P; DC+virginiamicina (V; DC+A+V; DC+A +P; DC+P+V; DC+A+P+V, constituídos por sete repetições de seis aves. O período pré-experimental foi de 15 dias e o fotoperíodo, de 17 horas de luz/dia. O ensaio 1 foi realizado em quatro semanas antes da MF, com as aves recebendo 110 g de ração contendo os aditivos. O ensaio 2 foi realizado durante os doze dias de MF, com as aves recebendo 10 g de milho moído, usado como veículo para diluir a dose dos aditivos consumida em 110 g de ração. O ensaio 3 foi realizado em seis semanas, durante o terceiro ciclo de produção, com as aves recebendo 110 g de ração, sem os aditivos, e as coletas tiveram início após as aves terem atingido 50% de postura. Antes da MF, o alho reduziu a massa de ovos em relação ao probiótico (48,2 vs. 39,8 g e, durante a MF, a virginiamicina e a mistura P+V reduziram a porcentagem de intestinos em relação ao alho (7,51 e 7,72 vs. 9,43, mas o peso e a porcentagem de baço não foram alterados. Após a MF, as variáveis não foram afetadas pelos tratamentos. Nas condições do experimento, os antimicrobianos usados não melhoram o desempenho de poedeiras antes, durante e após o estresse induzido pela MF em relação à ração sem aditivos.Three trials were carried out with 336 laying hens, aging 24 weeks and after second forced molt, caged in commercial conditions (550 cm²/bird to evaluate the use of bulb garlic (5 kg/t, probiotic (300 g/t and virginiamycin (20 g/t as additives in laying hens

    Full Text Available Os objetivos desse estudo foram: a determinar o limiar anaeróbio (LAn em jogadores de futebol com paralisia cerebral e nadadores participantes da Paraolimpíada de Sidney 2000 e; b analisar o comportamento do LAn em função das classes dos paratletas. Participaram do estudo, 28 atletas portadores de deficiência, sendo 11 jogadores de futebol com paralisia cerebral (classes: F36, F37 e F38 e 17 nadadores (14 homens e três mulheres (classes: S1 a S10 e B1. Nos jogadores de futebol, o LAn foi determinado em um protocolo progressivo e intermitente na esteira rolante. O LAn foi identificado como sendo a velocidade correspondente a 3,5mM de lactato sanguíneo. Na natação o LAn foi determinado por um protocolo incremental e intermitente de 3 x 200m. Após cada tiro houve coleta de sangue e por interpolação linear, foi calculada a velocidade correspondente a 4mM (LAn. A velocidade aeróbia máxima (Vamax e a correspondente ao LAn apresentaram uma tendência de melhora com o aumento da classe do jogador de futebol com paralisia cerebral. Entretanto, a proporção entre a velocidade do LAn e a Vamax (aproximadamente 80% foi bastante semelhante entre as classes. Na natação, a velocidade correspondente a 4mM aumentou em função do aumento das classes, indicando a limitação da capacidade funcional das classes mais baixas. Por outro lado, as concentrações de lactato em cada percentual da velocidade máxima de 200m foram muito semelhantes entre as classes, e também às obtidas em nadadores não portadores de deficiência. Com base nos resultados obtidos, podemos concluir que a classe (e portanto o nível de deficiência interfere na capacidade funcional aeróbia dos paratletas. Entretanto, a resposta de lactato ao exercício submáximo é semelhante entre as classes e também aos atletas não portadores de deficiência, sugerindo a validade do LAn para a avaliação aeróbia dos nadadores e dos jogadores de futebol com paralisia cerebral

    Full Text Available OBJETIVO: Comparar os novos valores previstos brasileiros de capacidade vital forçada e volume expiratório forçado no primeiro segundo para a espirometria obtidos em 2006 com os obtidos por outras equações de referência e validar os achados por meio da comparação com uma nova amostra de brasileiros normais. MÉTODOS: Realizou-se espirometria forçada, de acordo com as normas da Sociedade Brasileira de Pneumologia e Tisiologia, em 643 adultos brancos não-fumantes. Os valores previstos obtidos por pesquisadores brasileiros em 1992 e os obtidos por quatro grupos de pesquisadores estrangeiros foram comparados com os novos valores previstos brasileiros obtidos em 2006. Em uma segunda fase, os valores médios obtidos em 65 mulheres e 79 homens adultos foram comparados aos valores previstos obtidos pelas diversas equações de referência. RESULTADOS: O teste t para amostras pareadas revelou diferenças significativas entre os valores previstos obtidos pelas seis equações e os obtidos pela equação brasileira de 2006. Na segunda fase, observou-se que os valores previstos obtidos por Crapo et al. e os obtidos por Hankinson et al. para os méxico-americanos mostraram valores médios semelhantes aos observados na nova amostra. Porém, quando os valores previstos obtidos na nova amostra foram comparados com os obtidos por esses autores, discrepâncias foram observadas, com valores previstos altos e baixos. Os valores obtidos pela equação brasileira de 2006 mostraram as menores diferenças em comparação com os valores médios obtidos na nova amostra. CONCLUSÕES: Estes resultados sublinham a importância de se usar equações de predição para espirometria que sejam apropriadas para nossa população.OBJECTIVE: To compare the most recent (2006 predicted values of forced vital capacity and forced expiratory volume in one second for spirometry in Brazilians with those obtained using other reference equations and to validate the findings

    The quantitative analysis of Ex+|Em|=0.74〈1, which indicates that 1900-1937 Japanese macro economy shows that the formula can not meet M-L condition, and meanwhile, Japanese terms of trade are a weak positive correlation to trade balance, which means that without the involvement of government, the improvement of trade balance depends on the price of import and export rather than the amount of import and export cargo. Therefore, the quantitative analysis supports the logic conclusion that Japanese ADAS economic situation belongs to supply-restraint style. It argues that the theory based on the supposition of demand-restraint, especially Keynesian theory, should not be adapted when analyzing the operation of Japanese macro economy during the period of ex-WWII.%对日本1900~1937年宏观经济的数量分析表明,Ex+|Em|=0.74〈1,即不能满足马歇尔一勒纳条件;同时,日本的贸易条件与贸易收支为弱正相关,即如无政府干预,贸易收支的改善则依赖进出口物价而不是进出口物量。因此,数量分析支持日本的总供求态势属“供给约束型”的逻辑结论。笔者认为,分析战前日本宏观经济运行时,不应使用以“需求约束型经济”为上位前提的理论框架,特别是凯恩斯经济学的理论。
