Predicting individual performance in student project teams (2011)

Due to the critical role of communication in project teams, capturing and analyzing developer design notes and conversations for use as performance predictors is becoming increasing important as software development processes become more asynchronous. Current prediction methods require human Subject Matter Experts (SME) to laboriously examine and rank user content along various categories such as participation and the information they express. SEREBRO is an integrated courseware tool that captures social and development artifacts automatically and provides real time rewards, in the form of badges and titles, indicating a user's progress towards predefined goals using a variety of automated assessment measures. The tool allows for instructor visualization, involvement, and feedback in the ongoing projects and provides avenues for the instructor to adapt or adjust project scope or individual role assignments based on past or current individual performance levels. This paper evaluates and compares the use of two automated SEREBRO measures with SME content-based analysis and work product grades as predictors of individual performance. Data is collected from undergraduate software engineering teams using SEREBRO, whose automated measures of content and contribution perform as well as SME ratings and grades to suggest individual performance can be predicted in real-time.
Heat Transfer in Microchannels—2012 Status and Research Needs (2013)

Abstract Heat transfer and fluid flow in microchannels have been topics of intense research in the past decade. A critical review of the current state of research is presented with a focus on the future research needs. After providing a brief introduction, the paper addresses six topics related to transport phenomena in microchannels: single-phase gas flow, enhancement in single-phase liquid flow and flow boiling, flow boiling instability, condensation, electronics cooling, and microscale heat exchangers. After reviewing the current status, future research directions are suggested. Concerning gas phase convective heat transfer in microchannels, the antagonist role played by the slip velocity and the temperature jump that appear at the wall are now clearly understood and quantified. It has also been demonstrated that the shear work due to the slipping fluid increases the effect of viscous heating on heat transfer. On the other hand, very few experiments support the theoretical models and a significant effort should be made in this direction, especially for measurement of temperature fields within the gas in microchannels, implementing promising recent techniques such as molecular tagging thermometry (MTT). The single-phase liquid flow in microchannels has been established to behave similar to the macroscale flows. The current need is in the area of further enhancing the performance. Progress on implementation of flow boiling in microchannels is facing challenges due to its lower heat transfer coefficients and critical heat flux (CHF) limits. An immediate need for breakthrough research related to these two areas is identified. Discussion about passive and active methods to suppress flow boiling instabilities is presented. Future research focus on instability research is suggested on developing active closed loop feedback control methods, extending current models to better predict and enable superior control of flow instabilities. Innovative high-speed visualization and measurement techniques have led to microchannel condensation now being studied as a unique process with its own governing influences. Further work is required to develop widely applicable flow regime maps that can address many fluid types and geometries. With this, condensation heat transfer models can progress from primarily annular flow based models with some adjustments using dimensionless parameters to those that can directly account for transport in intermittent and other flows, and the varying influences of tube shape, surface tension and fluid property differences over much larger ranges than currently possible. Electronics cooling continues to be the main driver for improving thermal transport processes in microchannels, while efforts are warranted to develop high performance heat exchangers with microscale passages. Specific areas related to enhancement, novel configurations, nanostructures and practical implementation are expected to be the research focus in the coming years.
Perturbed Identity Matrices Have High Rank: Proof and Applications (2008)

We describe a lower bound for the rank of any real matrix in which all diagonal entries are significantly larger in absolute value than all other entries, and discuss several applications of this result to the study of problems in Geometry, Coding Theory, Extremal Finite Set Theory and Probability. This is partly a survey, containing a unified approach for proving various known results, but it contains several new results as well.
Analysis of Gingival Crevicular Fluid as Applied to the Diagnosis of Oral and Systemic Diseases (2007)

Gingival crevicular fluid (GCF), a serum transudate or inflammatory exudate, can be collected from the gingival crevice surrounding the teeth. As such, the fluid reflects the constituents of serum, the cellular response in the periodontium, and contributions from the gingival crevice. The study of GCF has focused on defining the pathophysiology of periodontal disease, and identification of a potential diagnostic test for active periodontitis. The majority of markers that have been identified as potential candidates for such a test are measures of inflammation (i.e., prostaglandin E2 (PGE2), neutrophil elastase, and the lysosomal enzyme beta-glucuronidase). Further, analysis of inflammatory markers in GCF may assist in defining how certain systemic disorders (e.g., diabetes mellitus) can modify periodontal disease, and how periodontal disease/periodontal inflammation can influence certain systemic disorders (i.e., cardiovascular/cerebrovascular diseases). Methodological concerns related to the collection and analysis of GCF are important factors that need to be considered when studying GCF. Practical concerns argue against the widespread clinical application of GCF as an adjunct to periodontal diagnosis. Rather, analysis of GCF-derived mediators in saliva may serve as a means of rapid screening for periodontal disease.
FUMS/spl trade/ fusion for improved aircraft MAAAP (2005)

Smiths has worked closely with the UK Ministry of Defence (MOD) to evolve a single fusion and decision support platform for helicopters, aeroplanes and engines that can address a number of military needs: a need for an advanced diagnostics, prognostics, lifing and intelligent management platform; a need for generating concise prognostic information; a need for a fusion, mining and automatic trending platform; a need for an expandable verification platform open for 3rd party tools; a need for a platform providing diverse applications to a wide range of users; and a need for a flexible platform providing military applications/benefits during evolution. This paper reports on a number of fusion and decision support tools developed by Smiths and MOD and embedded within the Smiths flight and usage management system (FUMStrade) to address these needs. The paper also presents the results obtained from applying the FUMStrade tools on MOD aircraft data
Extracting multi-thread with data localities for vector computers (2002)

In this paper, we propose a source-to-source compilation strategy to partition vectorized loop programs into multithread execution form. Each partitioned thread consists of instances of statements with localities in vector registers. The multi-threading scheme gives a novel combination of loop unrolling, statement instances reordering, index shifting, vector register reuse exploiting, and multi-threading. Experimental results show that our multithreading scheme assists vector compiler of Convex C38 series to reduce the number of memory accesses and the number of synchronizations among CPUs and usually obtains a better performance.
Identification of Low Molecular Weight Peptides in Gouda‐type Cheese and Evidence for the Formation of These Peptides from 23 N‐terminal Residues of αsl‐casein by Proteinases of <i>Streptococcus cremoris H61</i> (1986)

ABSTRACT Water‐soluble extracts from Gouda‐type cheese in a 0.05M sodium citrate buffer at pH 4.0 were fractionated by high‐pressure liquid chromatography (HPLC) before and after ripening for 1, 2, and 3 months. Three major peptides were isolated from each sample of extract, but size of the peaks increased with ripening period. The amino acid compositions of these peptides were similar to fragments of αsl‐casein, i.e., αsl‐CN(fl‐9), αsl‐CN(fl‐13) and αsl‐CN(fl‐14). αsl‐CN(fl‐23) was hydrolyzed by cellular proteases of Streptococcus cremoris H61; seven main peptides including αsl‐CN(fl‐9), αsl‐CN(fl‐13) and αsl‐CN(fl‐14) were isolated and characterized by HPLC. This suggests that hydrolysis of αsl‐CN(fl‐23) by lactic acid bacterial proteinase is one of the main pathways of αsl‐casein degradation during Gouda‐type cheese ripening.
Neural stem cells from protein tyrosine phosphatase sigma knockout mice generate an altered neuronal phenotype in culture (2006)

Our results imply a specific role for PTPsigma in the neuronal lineage, particularly in the form of inhibitory influences on neurite outgrowth, and demonstrate a role for tyrosine phosphatases in neuronal stem cell differentiation.
Including Biological Literature Improves Homology Search (2000)

Annotating the tremendous amount of sequence information being generated requires accurate automated methods for recognizing homology. Although sequence similarity is only one of many indicators of evolutionary homology, it is often the only one used. Here we find that supplementing sequence similarity with information from biomedical literature is successful in increasing the accuracy of homology search results. We modified the PSI-BLAST algorithm to use literature similarity in each iteration of its database search. The modified algorithm is evaluated and compared to standard PSI-BLAST in searching for homologous proteins. The performance of the modified algorithm achieved 32% recall with 95% precision, while the original one achieved 33% recall with 84% precision; the literature similarity requirement preserved the sensitive characteristic of the PSI-BLAST algorithm while improving the precision.
A Review of Production Scheduling (1981)

Production scheduling can be defined as the allocation of available production resources over time to best satisfy some set of criteria. Typically, the scheduling problem involves a set of tasks to be performed, and the criteria may involve both tradeoffs between early and late completion of a task, and between holding inventory for the task and frequent production changeovers. The intent of this paper is to present a broad classification for various scheduling problems, to review important theoretical developments for these problem classes, and to contrast the currently available theory with the practice of production scheduling. This paper will highlight problem areas for which there is both a significant discrepancy between practice and theory, and for which the practice corresponds closely to the theory.
Anti-allergic activity of 7-acetyl-5-oxo-5H-[1]benzopyrano[2, 3-b]pyridine(Y-9000) (1978)

The IgE mediated reactions such as 48 hr homologous passive cutaneous anaphylaxis (PCA) and active anaphylactic bronchoconstriction in rats were inhibited in a dose dependent manner by treatment with 7-acetyl-5-oxo-5H-[1]benzopyranol[2,3-b] pyridine (Y-9000) and disodium cromoglycate (DSCG) given intraperitoneally. The inhibitory activity of Y-9000 was to the same extent as that seen with DSCG. The IgE mediated reactions were also inhibited by oral treatment with Y-9000 but not with DSCG. In addition, the treatment with Y-9000 resulted in inhibition of IgG mediated reaction such as anaphylactic asthma in the passively sensitized guinea pigs and 4 hr heterologous PCA in rats. However, DSCG failed to prevent these reactions. Y-9000 also inhibited the active systemic anaphylaxis of the mouse and non-immunological reactions in rats such as histamine release after an intraperitoneal injection of dextran, anaphylactoid reaction and paw edema induced by the dextran, egg white or carrageenin. This agent had a stimulating effect on the adrenals, and showed glucocorticoid like activity, but bronchodilator and antagonistic activities on chemical mediators were nil. These results suggest that the anti-allergic activities of Y-9000 are elicited by inhibiting the release of allergic mediators in a manner similar to DSCG, and are partially mediated by stressor activity.
Synthese, Kristallstruktur und Eigenschaften eines neuen Sialons - SrSiAl2O3N2 (1998)

Das Sialon SrSiAl2O3N2 wurde durch Umsetzung von Siliciumdiimid, Aluminiumnitrid und Strontiumcarbonat unter N2-Atmosphäre im Hochfrequenzofen bei 1650 °C in grobkristalliner Form erhalten. Nach der Röntgenstrukturanalyse an Einkristallen ist die Titelverbindung isotyp mit LnSi3N5 (Ln = La, Ce, Pr, Nd). SrSiAl2O3N2 (P212121, a = 491,98(6), b = 789,73(7), c = 1134,94(18) pm, Z = 4, R1 = 0,0439, wR2 = 0,0939). Im Festkörper liegt eine Raumnetzstruktur allseitig eckenverknüpfter SiON3-, AlO3N- und AlO2N2-Tetraeder vor. Gitterenergetische Rechnungen mit dem MAPLE-Konzept bestätigen die eindeutige kristallographische Differenzierbarkeit zwischen N- und O- bzw. Al- und Si-Atomen (Al–O: 167,4(5)–170,6(6); Al–N: 175,4(6)–179,4(6); Si–O: 171,2(6); SiN: 176,7(6)–179,6(6) pm). Die Sr2+-Ionen sind in den Hohlräumen des (SiAl2O3N2)2–-Gerüstes positioniert (Sr–O: 250,4(6)–304,2(6); Sr–N: 287,4(6)–318,2(6) pm). Synthesis, Crystal Structure, and Properties of a New Sialon – SrSiAl2O3N2 The sialon SrSiAl2O3N2 was obtained as a coarsly crystalline solid by reaction of silicon diimide, aluminum nitride, and strontium carbonate under N2 atmosphere in a high-frequency furnace at 1650 °C. According to the single-crystal structure determination the title compound is isotypic with LnSi3N5 (Ln = La, Ce, Nd, Pr). SrSiAl2O3N2 (P212121, a = 491.98(6), b = 789.73(7), c = 1134.94(18) pm, Z = 4, R1 = 0.0439, wR2 = 0.0939). In the solid a three-dimensional network structure of corner sharing SiON3, AlO3N, and AlO2N2 tetrahedra occurs. Lattice energetic calculations using the MAPLE concept confirm an unequivocally correct crystallographic differentiation between N and O as well as Al and Si atoms, respectively (Al–O: 167.4(5)–170.6(6); Al–N: 175.4(6)–179.4(6); Si–O: 171.2(6); SiN: 176.7(6)–179.6(6) pm). The Sr2+ ions are located in the voids of the (SiAl2O3N2)2– framework (Sr–O: 250.4(6)–304.2(6); Sr–N: 287.4(6) 318.2(6) pm).
Dynamics of ligand-induced, Rac1-dependent anchoring of cadherins to the actin cytoskeleton (2002)

Cadherin receptors are key morphoregulatory molecules during development. To dissect their mode of action, we developed an approach based on the use of myogenic C2 cells and beads coated with an Ncad-Fc ligand, allowing us to mimic cadherin-mediated adhesion. We used optical tweezers and video microscopy to investigate the dynamics of N-cadherin anchoring within the very first seconds of bead-cell contact. The analysis of the bead movement by single-particle tracking indicated that N-cadherin molecules were freely diffusive in the first few seconds after bead binding. The beads rapidly became diffusion-restricted and underwent an oriented rearward movement as a result of N-cadherin anchoring to the actin cytoskeleton. The kinetics of anchoring were dependent on ligand density, suggesting that it was an inducible process triggered by active cadherin recruitment. This anchoring was inhibited by the dominant negative form of Rac1, but not that of Cdc42. The Rac1 mutant had no effect on cell contact formation or cadherin-catenin complex recruitment, but did inhibit actin recruitment. Our results suggest that cadherin anchoring to the actin cytoskeleton is an adhesion-triggered, Rac1-regulated process enabling the transduction of mechanical forces across the cell membrane; they uncover novel aspects of the action of cadherins in cell sorting, cell migration, and growth cone navigation.

Electronic laboratory utilization systems can effectively reduce unnecessary laboratory testing without compromising patient care.
Magnetic resonance imaging of rabbit brain after intracarotid injection of large multivesicular liposomes containing paramagnetic metals and DTPA (1988)

A procedure has been developed for the preparation of large (10- to 80-microns-diameter) multivesicular liposomes that contain magnetic resonance contrast agent (DTPA and either manganese or gadolinium). Blue dextran was observed to induce the formation of the large liposomes with dioleoylphosphatidylcholine and cholesterol (1:1 molar ratio) and with dipalmitoylphosphatidylcholine and cholesterol (1:1 molar ratio). The formation of the large liposomes is dependent upon mixing the blue dextran with the lipid films at temperatures above the transition point of the lipids. Tracer amounts of 153Gd were added to the aqueous phase to permit quantitation of the recovery of encapsulated materials. Liposomes that were prepared using equimolar ratios of phospholipid and cholesterol were stable in serum for more than 12 h. The ultrastructure of the large multivesicular liposomes reveals the existence of individual vesicles (greater than 2 micron diameter) bound together by a multilamellar coating. When injected into the internal carotid artery of the rabbit, the large liposomes became entrapped in the vascular bed primarily in the frontal and occipital regions of brain. The resulting emboli may provide a means to deliver drugs to a specific site in brain, such as a tumor, if the vascular bed of the site can be cannulated precisely.
Dissimilarity representation on functional spectral data for classification (2011)

Abstract In chemometrics, spectral data are typically represented by vectors of features in spite of the fact that they are usually plotted as functions of e.g. wavelengths and concentrations. In the representation, this functional information is thereby not reflected. Consequently, some characteristics of the data that can be essential for discrimination between samples of different classes or any other analysis are ignored. Examples are the continuity between measured points and the shape of curves. In the Functional Data Analysis (FDA) approach, the functional characteristics of spectra are taken into account by approximating the data by real valued functions, e.g. splines. Another solution is the Dissimilarity Representation (DR), in which classifiers are trained in a space built by dissimilarities with training examples or prototypes of each class. Functional information may be incorporated in the definition of the dissimilarity measure. In this paper we compare the feature‐based representation of chemical spectral data with three other representations: FDA, DR defined on raw data and DR defined on FDA descriptions. We analyze the classification results of these four representations for five data sets of different types, by using different classifiers. We demonstrate the importance of reflecting the functional characteristics of chemical spectral data in their representation, and we show when the presented approaches are more suitable.

Mucormycosis and Cutaneous Histoplasmosis in a Renal Transplant Recipient (1982)

Mucormycosis of the palate developed in a 31-year-old man while he was undergoing immunosuppression with prednisone and azathioprine after renal transplantation. The infection was excised and did not recur. Ten years later, while still receiving immunosuppressive therapy, cutaneous histoplasmosis of the fingers developed, which was treated successfully with intravenous amphotericin B. The occurrence of mucormycosis and histoplasmosis in this man emphasizes the need to suspect uncommon infections when unusual skin lesions occur in an immunosuppressed patient.
High expression of 90K (Mac‐2 BP) is associated with poor survival in node‐negative breast cancer patients not receiving adjuvant systemic therapies (2008)

90K (Mac-2 BP) expression was evaluated by immunohistochemistry in paraffin-embedded tissue from a consecutive series of lymph-node negative breast cancer patients who did not receive adjuvant systemic treatment. An independent series of patients served as validation set. The association of 90K expression with risk of recurrence and death was examined in survival analyses together with known prognostic factors. High levels of 90K expression (IHC score>8) were observed in 43 (25.3%) of 170 tumors examined. We found elevated risks of distant recurrence and overall mortality in patients with high 90K expression compared with patients with low 90K expression in their tumors. This increase persisted after adjusting for other prognostic factors in multivariate analysis (hazard ratio=4.084; p<0.001 for recurrence; hazard ratio=4.298; p<0.001 for death). These findings were confirmed in the validation set. Therefore, evaluation of 90K expression may be beneficial to identify lymph-node negative breast cancer patients at lower risk of disease recurrence and death.
<title>Inverse moire</title> (1997)

The usual moire method consists in projecting a grid, that is made of parallel straight lines, onto an object. Then a moire picture is obtained, which is made of cured fringes. In the inverse moire method, we compute a specific grid that is made of straight fringes. The object must be known, but small deformations from a known mean shape can be analyzed with very simple fringe processing. We show some examples of reconstruction by inverse moire.
Periodicity of redshift distribution in a T-3 universe (1990)

With the integrated Modem, SCART, and SCSI-2 interfaces, the d-box offers two Service Classes: Video/Audio Services, and Data Services. This paper discusses important technical consumer and commercial aspects of providing Multi-Media Services over satellite and cable involving both a TV and a PC connected to a Multi-Media Terminal (d-box).
Quadratic Optimization of Motion Coordination and Control (1990)

This paper presents algorithms for continuous-time quadratic optimization of motion control. Explicit solutions to the Hamilton-Jacobi equation for optimal control of rigid-body motion are found by solving an algebraic matrix equation. The system stability is investigated according to Lyapunov function theory, and it is shown that global asymptotic stability holds. It is also shown how optimal control and adaptive control may act in concert in the case of unknown or uncertain system parameters. The solution results in natural design parameters in the form of square weighting matrices as known from linear quadratic optimal control The proposed optimal control is useful both for motion control, trajectory planning, and motion analysis.
