Reconciliando Dados de Cunho Acadêmico

Academic data from the researchers' curricula are valuable data for several management activities, and several institution publishes data that can be seen as part of those curricula, including the Lattes Curricula System from CNPq, the Digital Bibliography & Library Project, ISI Web of Knowledge and the Portal Brasileiro de Informacao Cientifica from CAPES. However, integrating data from those sources can lead to inconsistency and/or incompleteness, as they can describe the same academic object in distinct ways. In this paper, we describe a tool aimed at improving the process of reconciling the description of academic objects obtained from distinct sources, called the Academic Data Reconciler. It performs similarity searches over two sets of academic objects from the same category, and aligns the pairs of more similar objects, allowing the user to transfer data from one object to the other. It allows, for example, to transfer data from the curriculum of a given researcher to others to whom they share academic activities or to transfer data from publishing houses, enforcing a more correct and consistent description of the reconciled data.
N-bromoacetyl-peptide substrate affinity labeling of vitamin K dependent carboxylase.

Vitamin K dependent carboxylase (carboxylase) is a membrane-associated endoplasmic reticular enzyme that catalyzes the conversion of certain glutamate residues of essential blood coagulation proteins to gamma-carboxyglutamyl (Gla) residues. A series of N-bromoacetyl-peptide substrate affinity labels based on the Gla domain of these blood-clotting proteins was synthesized, and the substrate and inactivator kinetic parameters were assessed. The most promising of these affinity peptides, N-bromoacetyl-FLEELY, was both substrate for carboxylase and an irreversible time-dependent inactivator of the enzyme, inactivating 80% of carboxylase under pseudo-first-order conditions. Addition of saturating amounts of a competing peptide substrate completely abolished the inhibitory properties of N-bromoacetyl-FLEELY, consistent with inactivation occurring at the active site. The partition ratio of inactivation/carboxylation was 1/30. The 94-kDa carboxylase was purified to 15-50% purity by a modification of a recent protocol [Wu, S. -M. , Morris, D. P., & Stafford, D. W. (1991) Proc. Natl. Acad. Sci. U.S.A. 88, 2236-2240] and covalently labeled with N-bromoacetyl-FLEEL[125I]Y. On silver-stained 10% sodium dodecyl sulfate-polyacrylamide gels, the predominant radiolabeled band was the 94,000 molecular weight species. This result independently validates that the 94-kDa protein is a carboxylase.
Marital quality, marital disruption, and immune function.

&NA; Marital disruption is associated with significant increases in a variety of psychologic and physical disorders. In order to examine psychologic and physiologic mediators, self‐report data and blood samples were obtained from 38 married women and 38 separated/divorced women. Among married subjects, poorer marital quality was associated with greater depression and a poorer response on three qualitative measures of immune function. Women who had been separated 1 year or less had significantly poorer qualitative and quantitative immune function than their sociodemographically matched married counterparts. Among the separated/divorced cohort, shorter separation periods and greater attachment to the (ex)husband were associated with poorer immune function and greater depression. These data are consistent with epidemiologic evidence linking marital disruption with increased morbidity and mortality.
Adaptive classification model based on artificial immune system for breast cancer detection

Early stage asymmetric signs in breast that can be captured by the screening-digital mammography can be used for a precocious diagnosis of breast cancer. Conventional mammography screening fails to detect subtle anomalies, so computer-aided methods are studied in order to improve the accuracy of image analysis. To classify the images into asymmetric and normal cases, in this paper we investigated the performance of an Adaptive Artificial Immune System (A2INET) classifier. To test the efficiency of the algorithm, two public datasets have been considered: 32 pairs of mammographic images including MLO projection retrieved from Digital Database for Screening mammographic (DDSM) and 30 ones from Mammographic Image Analysis Society (mini-MIAS) databases. Results show that A2INET yields best results with respect to the other more conventional classifiers.
Estimation of the angle of humeral torsion from digital images of dry humeri of South Indian origin

Objectives:The present study was undertaken to measure the angle of humeral torsion (AHT) on digital images. The aimsof the present study were to estimate the: i) angle of humeral torsion, ii) difference in the AHT between right and left humeri,and iii) reliability of the method. Methods: A total of 185 unpaired humeri (101 right and 84 left) from South India of unknown age and sex available at thedepartment of anatomy were studied. Reference points for the long axis of the upper end of the humerus were marked. Anend-on digital photograph of the articular surface of the head was taken. Using appropriate software, lines were drawn todefine the AHT. Printouts of the above images were taken and the AHT measured with a protractor. The mean and standard deviation of the AHT were calculated for all the humeri and separately for each side. The unpaired t-test was used todetermine the significance of the side differences. Inter- and intra-observer reliability was estimated using the technical errorof measurement (TEM), relative technical error of measurement (rTEM) and coefficient of reliability (R). Results: The mean AHT considering all the humeri was 59.65°±10.97. The corresponding values on the right and left sidewere 57.85°±9.80 and 61.83°±11.93 respectively, with a significantly greater (p=0.02) mean AHT on the left side.Acceptable rTEM values of 4.27% and 7.62% for intra-observer and inter-observer repeat measurements were obtained. Conclusion:The mean values of the AHT lie within the range previously described, with significantly greater values on theleft side. The method described showed acceptable inter- and intra-observer reliability
Simultaneous measurements of particulate and gas‐phase water‐soluble organic carbon concentrations at remote and urban‐influenced locations

The sources, sinks, and overall importance of water‐soluble organic carbon (WSOC) in the atmosphere are not well understood. Although the primary historical focus has been on particulate WSOC (WSOCP), here we also present results obtained using a newly developed technique that additionally measures gas‐phase water‐soluble organic carbon (WSOCG). These first‐of‐their‐kind measurements show that WSOCG can often be more than ten times larger than WSOCP at both urban and remote locations. The average fraction of WSOC residing in the gas phase (fg = WSOCG/(WSOCG + WSOCP)) at five various field sites ranged from 0.64 to 0.93, implying significant differences in WSOC phase partitioning between locations. At Houston, TX, and Summit, Greenland, a repeatable diurnal pattern was observed, with minimum values for fg occurring at night. These trends likely are due, at least in part, to temperature and/or relative humidity related gas‐to‐particle partitioning. These coincident measurements of WSOC in both the gas and particle phases indicate that a relatively large reservoir of water‐soluble organic mass is not taken into account by measurements focused only on WSOCP. In addition, a significant amount of WSOCG is available to form WSOCP or enter cloud droplets depending on the chemical and physical properties of the droplets and/or aerosols present.
Stress‐induced activation of the immediate early gene Arc (activity‐regulated cytoskeleton‐associated protein) is restricted to telencephalic areas in the rat brain: relationship to c‐fos mRNA

Arc is an effector immediate early gene whose expression is induced in situations of increased neuronal activity. However, there is no report on the influence of stress on Arc expression. Here, we compared the induction of both c‐fos and Arc mRNAs in the brain of rats exposed to one of three different stressful situations: novel environment, forced swimming and immobilization. An absent or weak c‐fos mRNA signal was observed in control rats, whereas those exposed to one of three stressors showed enhanced c‐fos expression in a wide range of brain areas. Constitutive Arc expression was observed in some areas such as cortex, striatum, hippocampus, reticular thalamic nucleus and cerebellar cortex. In response to stressors, a strong induction of Arc was observed, but the pattern was different from that of c‐fos. For instance, activation of Arc but not c‐fos was observed in the nucleus accumbens after immobilization and in the hippocampus after novel environment. No Arc induction was observed in diencephalic and brainstem areas. The present data show that Arc has a neuroanatomically restricted pattern of induction in the brain after emotional stress. Telencephalic activation suggests that a more intense induction of synaptic plasticity is occurring in this area after exposure to emotional stressors.
Collaborative filtering motivated automatic photo tagging

Personal photographs shared in social network websites show a wide range of variations in illumination, pose and expression. As a result, conventional face recognition methods show poor performance in such uncontrolled setting. To resolve this problem, we explore incorporating associated social network context into visual face recognition system. Motivated by collaborative filtering technique, a new method for photo tagging task is proposed in this paper. Meanwhile, a large-scale social network image dataset (SNRR-collection) is collected in this work. Experiments evaluated on SNRR-collection dataset demonstrate the effectiveness of our proposed model.
Single-Anchor Indoor Localization Using ESPAR Antenna

In this letter, a new single-anchor indoor localization concept employing electronically steerable parasitic array radiator (ESPAR) antenna has been proposed. The new concept uses a simple fingerprinting algorithm adopted to work with directional main beam and narrow minimum radiation patterns of ESPAR antenna that scans 360 ° area around the base station, while the signal strength received from a mobile terminal is being recorded for each configuration. The letter describes the antenna design and necessary fingerprinting algorithm expansion and shows measurements of the proof-of-concept prototype performed within the experimental setup. Localization results obtained from indoor measurements indicate that the proposed concept can provide better results than the similar approach based on a switched-beam antenna introduced by Giorgetti (IEEE Commun. Lett., vol. 13, no. 1, pp. 58-60, Jan. 2009).
Birth Weight and Social Trust in Adulthood

Social trust forms the fundamental basis for social interaction within societies. Understanding the cognitive architecture of trust and the roots of individual differences in trust is of key importance. We predicted that one of the factors calibrating individual levels of trust is the intrauterine flow of nutrients from mother to child as indexed by birth weight. Birth weight forecasts both the future external environment and the internal condition of the individual in multiple ways relevant for social cognition. Specifically, we predicted that low birth weight is utilized as a forecast of a harsh environment, vulnerable condition, or both and, consequently, reduces social trust. The results of the study reported here are consistent with this prediction. Controlling for many confounds through sibling and panel designs, we found that lower birth weight reduced social trust in adulthood. Furthermore, we obtained tentative evidence that this effect is mitigated if adult environments do not induce stress.
Can Linguistic Predictors Detect Fraudulent Financial Filings

ABSTRACT: Extensive research has been done on the analytical and empirical examination of financial data in annual reports to detect fraud; however, there is scant research on the analysis of text in annual reports to detect fraud. The basic premise of this research is that there are clues hidden in the text that can be detected to determine the likelihood of fraud. In this research, we examine both the verbal content and the presentation style of the qualitative portion of the annual reports using natural language processing tools and explore linguistic features that distinguish fraudulent annual reports from nonfraudulent annual reports. Our results indicate that employment of linguistic features is an effective means for detecting fraud. We were able to improve the prediction accuracy of our fraud detection model from initial baseline results of 56.75 percent accuracy, using a “bag of words” approach, to 89.51 percent accuracy when we incorporated linguistically motivated features inspired by our infor.
Results from Polish Spondyloarthritis Initiative registry (PolSPI) – methodology and data from – the first year of observation

Objectives Report on one-year results from the Polish Spondyloarthritis Initiative registry (PolSPI), containing the cross-sectional analysis of clinical and imaging data as well as database methodology. Material and methods The PolSPI registry includes patients with axial (axSpA) and peripheral (perSpA) spondyloarthritis according to ASAS classification criteria, and/or patients with ankylosing spondylitis according to modified New York criteria, psoriatic arthritis according to CASPAR criteria, arthropathy in inflammatory bowel disease, reactive arthritis, juvenile spondyloarthritis or undifferentiated spondyloarthritis. Epidemiologic data and history of signs, symptoms and treatment of spondyloarthritis are collected and assessment of disease activity is performed. Radiographic images of sacroiliac joint, cervical and lumbar spine, and results of bone densitometry are collected. Every 6 months blood samples for inflammatory markers, and for long-term storage are taken. Results During a one-year period from September 2015 to August 2016, 63 patients were registered on an electronic database; 44 (69.8%) of patients were classified as axial spondyloarthritis (axSpA) and 19 (30.2%) as peripheral spondyloarthritis (perSpA) according to ASAS criteria. Statistically significant differences between axSpA and perSpA were discovered in the percentage of HLA-B27 antigen occurrence (92.6% and 50%, respectively), BASDAI (2.8% and 4.1%, respectively), DAS 28 (2.66% and 4.03%, respectively), percentage of peripheral arthritis (20% and 88.8%, respectively), enthesitis (26.7% and 70.6%, respectively), dactylitis (6.7% and 88.9%, respectively), as well as extra-articular symptoms: acute anterior uveitis (26.7% and 5.6%, respectively) and psoriasis (6.9% and 55.6%, respectively). Patients with axSpA had significantly higher mean grade of sacroiliac involvement according to New York criteria, higher mSASSS score, and lower T-score in femoral neck in bone densitometry. Conclusions At the early stage of the disease patients with axSpA compared to those with perSpA, have more advanced structural damage of sacroiliac joints and spine, and lower bone mineral density in the femoral neck. In the upcoming years the PolSPI registry will prospectively follow-up patients with SpA, recording response to treatment and carrying out research on interaction of inflammation and bone remodelling.
Aspects of Append-Based Database Storage Management on Flash Memories

New storage technologies, such as Flash and Non- Volatile Memories, with fundamentally different properties are appearing. Leveraging their performance and endurance requires a redesign of existing architecture and algorithms in modern high performance databases. Multi-Version Con- currency Control (MVCC) approaches in database systems, maintain multiple timestamped versions of a tuple. Once a transaction reads a tuple the database system tracks and returns the respective version eliminating lock-requests. Hence under MVCC reads are never blocked, which leverages well the excellent read performance (high throughput, low latency) of new storage technologies. Upon tuple updates, however, established implementations of MVCC approaches (such as Snapshot Isolation) lead to multiple random writes - caused by (i) creation of the new and (ii) in-place invalidation of the old version - thus generating suboptimal access patterns for the new storage media. The combination of an append based storage manager operating with tuple granularity and snapshot isolation addresses asymmetry and in-place updates. In this paper, we highlight novel aspects of log-based storage, in multi-version database systems on new storage media. We claim that multi-versioning and append-based storage can be used to effectively address asymmetry and endurance. We identify multi-versioning as the approach to address data- placement in complex memory hierarchies. We focus on: version handling, (physical) version placement, compression and collocation of tuple versions on Flash storage and in complex memory hierarchies. We identify possible read- and cache- related optimizations.
Analysis and modeling of thick-metal spiral inductors on silicon

In this paper, the analysis and modeling of thick-metal spiral inductors are addressed. The actual improvements of metal thickening in terms of quality factor are evaluated and related to skin and proximity effects. The inductance decrease due to metal thickening is also investigated and modeled using a modified current-sheet expression. The proposed formula achieves higher accuracy compared to the original one revealing errors below 5% even for thickness-to-width ratio up to 2.5.
Fluorescence studies of the conformation of pyrene-labeled tropomyosin: effects of F-actin and myosin subfragment 1.

The fluorescence of pyrene-TM [rabbit skeletal tropomyosin (TM) labeled at Cys with N-(1-pyrenyl)maleimide] consists of monomer and excimer bands [Betcher-Lange, S. , & Lehrer, S.S. (1978) J. Biol. Chem. 253, 3757-3760]; an increase in excimer fluorescence with temperature is due to a shift in equilibrium from a chain-closed state (N) to a chain-open state (X) associated with a helix pretransition [Graceffa, P., & Lehrer, S.S. (1980) J. Biol. Chem. 255, 11296-11300]. In this study, we show that the presence of appreciable excimer fluorescence at temperatures below the N----X pretransition (initial excimer) is due to perturbation of the TM chain-chain interaction by the pyrenes at Cys-190. Fluorescence and ATPase titrations indicated that the label caused a decrease in TM binding to F-actin primarily due to reduced end to end TM interactions on the actin filament. Under conditions where pyrene-TM was bound to F-actin, however, the excimer fluorescence did not increase with temperature, indicating that F-actin stabilizes tropomyosin by inhibiting the N----X transition. The binding of myosin subfragment 1 (S1) to pyrene-TM-F-actin at low ratios to actin caused time-dependent changes in fluorescence. After equilibrium was reached, the initial excimer fluorescence was markedly reduced and remained constant over the pretransition temperature range. Further stabilization of tropomyosin conformation on F-actin is therefore associated with S1 binding. Effects of the binding of S1 to the F-actin-tropomyosin thin filament on the state of tropomyosin were studied by monitoring the monomer fluorescence of pyrene-TM. (ABSTRACT TRUNCATED AT 250 WORDS)
Vitamin B12 Assay in Body Fluids using Euglena gracilis

The methods of assay of vitamin B12 most generally used depend on the fact that some lactobacilli require this vitamin as an essential growth factor and that growth is proportional to the amount available over a certain range of concentration. Some desoxynucleotides (Shive, Sibley, and Rogers, 1951), desoxyribonucleosides and thymidine particularly, and many other substances too, have, however, been found to replace vitamin B12, although in relatively large amounts only. Assays with lactobacilli then are not entirely specific and this fact, combined with rather low sensitivity, makes these methods unsatisfactory for detecting the low concentrations of vitamin B12 found in some body fluids. The results of lactobacillus assays of whole blood of a number of animal species (Couch, Olcese, Witten, and Colby, 1950), of milk of a number of animal species (Collins, Harper, Schreiber, and Elvehjem, 1951), of urine of subjects receiving vitamin B12 therapy (Chow, Lang, Davis, Conley, and Ellicott, 1950), and of human urine (Girdwood, 1951) have, however, been reported. Plate assays with a Bact. coli mutant requiring vitamin B12 as a growth factor (Bessell, Harrison, and Lees, 1950) are also lacking in sensitivity, but, because of the simplicity of the method and rapidity of growth, are useful for the assay of large concentrations such as are found in urine after injection of vitamin B12 (Chesterman, Cuthbertson, and Pegler, 1951). Chemical methods of assay are being developed (Boxer and Rickards, 1951; Fantes, Ireland, and Green, 1950), but are still insufficiently sensitive to detect concentrations normally found in body fluids. The use of an alga, Euglena gracilis var. bacillaris, for the assay of vitamin B12, crystalline and in liver extract, was described by Hutner, Provasoli, Stokstad, Hoffmann, Belt, Franklin, and Jukes (1949). Assays with the Euglena by both the tube and plate method of a variety of material
Adaptive–Robust Control of Euler–Lagrange Systems With Linearly Parametrizable Uncertainty Bound

This brief proposes a new adaptive–robust control (ARC) architecture for a class of uncertain Euler–Lagrange (EL) systems where the upper bound of the uncertainty satisfies linear in the parameters structure. Conventional ARC strategies either require structural knowledge of the system or presume that the overall uncertainties or its time derivative are norm bounded by a constant. Due to the unmodeled dynamics and modeling imperfection, true structural knowledge of the system is not always available. Furthermore, for the class of systems under consideration, prior assumption, regarding the uncertainties (or its time derivative) being upper bounded by a constant, puts a restriction on the states beforehand. Conventional ARC laws invite overestimation–underestimation problem of switching gain. Toward this front, adaptive switching-gain-based robust control (ASRC) is proposed, which alleviates the overestimation–underestimation problem of switching gain. Moreover, ASRC avoids any presumption of constant upper bound on the overall uncertainties and can negotiate uncertainties regardless of being linear or nonlinear in parameters. Experimental results of ASRC using a wheeled mobile robot note improved control performance in comparison with the adaptive sliding mode control.
Treatment of Femoral Fractures in Children by Pediatric Orthopedists: Results of a 1998 Survey

This study aimed to determine treatment preference of various femoral fracture patterns in children by pediatric orthopedists and whether it is practice dependent. In September 1998, members of the Pediatric Orthopedic Society of North America were surveyed to determine their current preferences in treating each of four middle one-third femoral fracture patterns in four age groups. Forty-four percent (286/656) of those surveyed responded. For each fracture pattern, operative treatment was increasingly preferred over nonoperative as patient age increased, and the preferred treatments within the operative and nonoperative categories changed significantly as patient age increased. Fourteen specific cases of femoral head avascular necrosis were noted after rigid reamed and unreamed rodding. There is a statistically significant trend by pediatric orthopedists to treat older children's femur fractures operatively and younger children's nonoperatively. The consensus treatment is age dependent. The numerous cases of avascular necrosis after rigid rodding are a concern.
