A Competence Management Supported by Recommendation Mechanism

The constant changes in social, economic and political scenario have required tightly response time from organizations and ability to reconfigure its resources to remain competitive. In this context, this article aims at presenting a recommendation mechanism for a competence model to improve the competence gaps analysis and identify the better Development Plan for Employees (DPE), which consist of training and development for knowledge development through the use of a corporate competence management system. Besides, this article presents a case study that shows the gain of use the recommendation mechanism in a corporate environment which has a competence management system.
The ReAl Computer Architecture

This proposal describes a hardware-software interface which can put into effect a practically unlimited number of processing resources and which allows for completely describing and exploiting the inherent parallelism of the application problems. Appropriate hardware consists of processing resources, platform resources, and storage means. The particular processing resource is not a complete processor but some kind of a comparatively simple operation unit. The proposed architectural principles may lead to: (i) Instruction set architectures which can cope with a trans- finite number of hardware resources. (ii) Processing circuits containing resources of intermediate granularity and appropriately optimized interconnects.
The Dominance, Prestige, and Leadership Account of Social Power Motives

The power motive predicts influential social behaviour; however, its heterogeneous conceptualisations have produced inconsistent results. To overcome this problem, we developed and validated a unitary taxonomy of social power motives based on established delineations of social hierarchies: the dominance, prestige, and leadership account. While we could measure these motives both reliably and distinctively (study 1), we also showed they strongly related to a common power desire (study 2). Assessing their nomological networks (studies 3 and 4), we demonstrated distinct associations between the dominance motive (D: wanting to coerce others into adhering to one's will) and anger and verbal aggression; the prestige motive (P: wanting to obtain admiration and respect) and the fear of losing reputation and claiming to have higher moral concerns; the leadership motive (L: wanting to take responsibility in and for one's group) and emotional stability and helping behaviour. Furthermore, while D uniquely predicted agonistic/retaliatory behaviour in dictator games (study 5), L uniquely predicted the attainment of higher employment ranks in various professions (study 7). Finally, at least to some degree, P and L related positively, and D negatively to prosocial donating behaviour (study 6). This taxonomy represents a novel and powerful approach to predicting influential social behaviour. © 2018 European Association of Personality Psychology
Merit functions and descent algorithms for a class of variational inequality problems

We consider a variational inequality problem, where the cost mapping is the sum of a single-valued mapping and the subdifferential mapping of a convex function. For this problem we introduce a new class of equivalent optimi7ation formulations; based on them, we also provide the first convergence analysis of descent algorithms for the problem. The optimization formulations constitute generalizations of those presented by Auchmuty [Auc89]. and the descent algorithms are likewise generalizations of those of Fukushima [Fuk92], Larsson and Patriksson [LaP94] and several others, for variational inequality problems with single-valued cost mappings
Time-varying Burg method for speech analysis

The Burg method determines the reflection coefficients of the lattice filter under the assumption of a stationary process. In this contribution, a time-varying Burg method based on least squares estimation is proposed estimating reflection coefficients which are time-varying within the analyzed frames. For that purpose, the trajectory of the reflection coefficients is parameterized by piecewise linear basis function. To yield estimation results of adjacent frames which are continuously connected in terms of the reflection coefficients, the coefficients of the current frame are constrained in a way that the trajectory starts from the final coefficient vector of the last frame. This leads to a block-based estimation procedure which can be performed in an adaptive way since the estimation of a frame depends only on the current frame and on the last frames.
Treatment of Strip Perforation Using Root MTA: A Case Report

Root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, and adversely affect the prognosis of the treatment. Recently, Iranian mineral trioxide aggregate [Root MTA] has been introduced as an ideal material for perforation repair. In this article a successful repair of strip root perforation of mandibular molar using Root MTA is presented with 15-month follow-up. This case suggests that Root MTA may be a substitute material for the treatment of strip perforation; however, more clinical studies with larger sample size and longer follow-ups are needed.
The HOM problem is decidable

We provide an algorithm that, given a tree homomorphism H and a regular tree language L represented by a tree automaton, determines whether H(L) is regular. This settles a question that has been open for a long time. Along the way, we develop new constructions and techniques which are interesting by themselves, and provide several significant intermediate results. For example, we prove that the universality problem is decidable for languages represented by tree automata with equality constraints, and that the equivalence and inclusion problems are decidable for images of regular tree languages through tree homomorphisms. Our algorithms are based on the following constructions. We describe a simple transformation for converting a tree automaton with equality constraints into a tree automaton with inequality constraints recognizing the complementary language. We also define a new class of automata with arbitrary inequality constraints and a particular kind of equality constraints. An automaton of this new class essentially recognizes the intersection of a tree automaton with inequality constraints and the image of a regular tree language through a tree homomorphism. We prove decidability of emptiness and finiteness for this class by a pumping mechanism.
Gene Clusters, Molecular Evolution and Disease: A Speculation

Traditionally eukaryotic genes are considered independently expressed under the control of their promoters and cis-regulatory domains. However, recent studies in worms, flies, mice and humans have shown that genes co-habiting a chromatin domain or “genomic neighborhood” are frequently co-expressed. Often these co-expressed genes neither constitute part of an operon nor function within the same biological pathway. The mechanisms underlying the partitioning of the genome into transcriptional genomic neighborhoods are poorly defined. However, cross-species analyses find that the linkage among the co-expressed genes of these clusters is significantly conserved and that the expression patterns of genes within clusters have coevolved with the clusters. Such selection could be mediated by chromatin interactions with the nuclear matrix and long-range remodeling of chromatin structure. In the context of human disease, we propose that dysregulation of gene expression across genomic neighborhoods will cause highly pleiotropic diseases. Candidate genomic neighborhood diseases include the nuclear laminopathies, chromosomal translocations and genomic instability disorders, imprinting disorders of errant insulator function, syndromes from impaired cohesin complex assembly, as well as diseases of global covalent histone modifications and DNA methylation. The alteration of transcriptional genomic neighborhoods provides an exciting and novel model for studying epigenetic alterations as quantitative traits in complex common human diseases.
Retrieval of semitransparent ice cloud optical thickness from atmospheric infrared sounder (AIRS) measurements

An approach is developed to infer the optical thickness of semitransparent ice clouds (when optical thickness is less than 5) from Atmospheric Infrared Sounder (AIRS) high spectral resolution radiances. A fast cloud radiance model is developed and coupled with an AIRS clear-sky radiative transfer model for simulating AIRS radiances when ice clouds are present. Compared with more accurate calculations based on the discrete ordinates radiative transfer model, the accuracy of the fast cloud radiance model is within 0.5 K (root mean square) in terms of brightness temperature (BT) and runs three orders of magnitude faster. We investigate the sensitivity of AIRS spectral BTs and brightness temperature difference (BTD) values between pairs of wavenumbers to the cloud optical thickness. The spectral BTs for the atmospheric window channels within the region 1070-1135 cm/sup -1/ are sensitive to the ice cloud optical thickness, as is the BTD between 900.562 cm/sup -1/ (located in an atmospheric window) and 1558.692 cm/sup -1/ (located in a strong water vapor absorption band). Similarly, the BTD between a moderate absorption channel (1587.495 cm/sup -1/) and the strong water absorption channel (1558.692 cm/sup -1/) is sensitive to ice cloud optical thickness. Neither of the aforementioned BTDs is sensitive to the effective particle size. Thus, the optical thickness of semitransparent ice clouds can be retrieved reliably. We have developed a spectrum-based approach and a BTD-based method to retrieve the optical thickness of semitransparent ice clouds. The present retrieval methods are applied to a granule of AIRS data. The ice cloud optical thicknesses derived from the AIRS measurements are compared with those retrieved from the Moderate Resolution Imaging Spectroradiometer (MODIS) 1.38and 0.645-/spl mu/m bands. The optical thicknesses inferred from the MODIS measurements are collocated and degraded to the AIRS spatial resolution. Results from the MODIS and AIRS retrievals are in reasonable agreement over a wide range of optical thicknesses.
Fast Modeling with a Single-Point Laser Range Finder

This paper presents methodology for integrating a small, singlepoint laser range finder into a wearable augmented reality system. We introduce a method using the laser range finder to incrementally build 3D panoramas from a fixed observer’s location. To build a 3D panorama semi-automatically, we track the system’s orientation and use the sparse range data acquired as the user looks around in conjunction with real-time image processing to construct geometry around the user’s position. Using full 3D panoramic geometry, it is possible for new virtual objects to be placed in the scene with proper lighting and occlusion by real world objects, which increases the expressivity of the AR experience.
Proteinases of common pathogenic bacteria degrade and inactivate the antibacterial peptide LL‐37

Effectors of the innate immune system, the anti‐bacterial peptides, have pivotal roles in preventing infection at epithelial surfaces. Here we show that proteinases of the significant human pathogens Pseudomonas aeruginosa, Enterococcus faecalis, Proteus mirabilis and Streptococcus pyogenes, degrade the antibacterial peptide LL‐37. Analysis by mass spectrometry of fragments generated by P. aeruginosa elastase in vitro revealed that the initial cleavages occurred at Asn‐Leu and Asp‐Phe, followed by two breaks at Arg‐Ile, thus inactivating the peptide. Proteinases of the other pathogens also degraded LL‐37 as determined by SDS‐PAGE. Ex vivo, P. aeruginosa elastase induced LL‐37 degradation in human wound fluid, leading to enhanced bacterial survival. The degradation was blocked by the metalloproteinase inhibitors GM6001 and 1, 10‐phenantroline (both of which inhibited P. aeruginosa elastase, P. mirabilis proteinase, and E. faecalis gelatinase), or the inhibitor E64 (which inhibited S. pyogenes cysteine proteinase). Additional experiments demonstrated that dermatan sulphate and disaccharides of the structure [ΔUA(2S)‐GalNAc(4,6S)], or sucroseoctasulphate, in‐hibited the degradation of LL‐37. The results indicate that proteolytic degradation of LL‐37 is a common virulence mechanism and that molecules which block this degradation could have therapeutic potential.
A Systematic Analysis of Eluted Fraction of Plasma Post Immunoaffinity Depletion: Implications in Biomarker Discovery

Plasma is the most easily accessible source for biomarker discovery in clinical proteomics. However, identifying potential biomarkers from plasma is a challenge given the large dynamic range of proteins. The potential biomarkers in plasma are generally present at very low abundance levels and hence identification of these low abundance proteins necessitates the depletion of highly abundant proteins. Sample pre-fractionation using immuno-depletion of high abundance proteins using multi-affinity removal system (MARS) has been a popular method to deplete multiple high abundance proteins. However, depletion of these abundant proteins can result in concomitant removal of low abundant proteins. Although there are some reports suggesting the removal of non-targeted proteins, the predominant view is that number of such proteins is small. In this study, we identified proteins that are removed along with the targeted high abundant proteins. Three plasma samples were depleted using each of the three MARS (Hu-6, Hu-14 and Proteoprep 20) cartridges. The affinity bound fractions were subjected to gelC-MS using an LTQ-Orbitrap instrument. Using four database search algorithms including MassWiz (developed in house), we selected the peptides identified at <1% FDR. Peptides identified by at least two algorithms were selected for protein identification. After this rigorous bioinformatics analysis, we identified 101 proteins with high confidence. Thus, we believe that for biomarker discovery and proper quantitation of proteins, it might be better to study both bound and depleted fractions from any MARS depleted plasma sample.
Efficacy and safety of testosterone replacement therapy in men with hypogonadism: A meta-analysis study of placebo-controlled trials

The purpose of the present meta-analysis was to evaluate the efficacy and safety of testosterone replacement therapy in men with hypogonadism. A search was conducted for appropriate randomized controlled trials and the data from 16 trials were pooled. The intended primary outcome of the present study was to determine the efficacy and safety of testosterone replacement therapy. The current data demonstrated that scores for Aging Male Symptoms (AMS) were significantly reduced following testosterone replacement therapy, with a mean decrease in AMS score of 1.52 [95% confidence interval (CI), 0.72 to 2.32; P=0.0002]. Testosterone replacement therapy increased lean body mass [mean difference (MD), 1.22; 95% CI, 0.33 to 2.11; P=0.007], reduced fat mass in a non-significantly manner (MD, −0.85; 95% CI, −1.74 to 0.04; P=0.06) and significantly reduced total cholesterol (MD, −0.16; 95% CI, −0.29 to −0.03; P=0.01). No significant differences were identified in body weight (MD, 0.09; 95% CI, −1.13 to 1.31; P=0.89), body mass index (MD, 0.10; 95% CI, −0.62 to 0.82; P=0.78) or bone mineral density (MD, −0.01; 95% CI, −0.03 to 0.02; P=0.60). Average prostate volume increased (MD, 1.58; 95% CI, 0.6 to 2.56; P=0.002) following testosterone replacement therapy, but the levels of prostate-specific antigen (PSA) (MD, 0.10; 95% CI, −0.03 to 0.22; P=0.14) and the International Prostate Symptom Scores (MD, 0.01; 95% CI, −0.37 to 0.39; P=0.96) did not change. In conclusion, testosterone replacement therapy improves quality of life, increases lean body mass, significantly decreases total cholesterol, and is well-tolerated and safe for men with hypogonadism who are exhibiting PSA levels of <4 ng/ml.
An Approach to UNIX Security Logging

Off-line intrusion detection systems rely on logged data. However, the logging mechanism may be complicated and time-consuming and the amount of logged data tends to be very large. To counter these problems we suggest a very simple and cheap logging method, lig t-weight logging. It can be easily implemented on a Unix system, particularly on the Solaris operating system from Sun. It is based on logging every invocation of the exec(2) system call together with its arguments. We use data from realistic intrusion experiments to show the benefits of the proposed logging and in particular that this logging method consumes as little system resources as comparable methods, while still being more effective.
Chinese university students’ loneliness and generalized pathological Internet use: A longitudinal cross-lagged analysis

We examined the reciprocal relationship between loneliness and generalized pathological Internet use (GPIU) with a sample of 361 (141 men and 220 women, M age = 18.47 years) university freshmen in China. A fully cross-lagged panel design was used, in which loneliness and GPIU were assessed at 3 time points. The results were as follows: (a) GPIU had a higher level of stability than did loneliness, and (b) the relationship between loneliness and GPIU was dynamic and bidirectional. Specifically, loneliness positively predicted GPIU across time, GPIU at Time 2 (3 months after initial measurement) positively predicted loneliness at Time 3 (6 months after initial measurement), and the link between baseline loneliness and Time 3 loneliness was mediated by increased GPIU at Time 2. Our findings have implications for the treatment and prevention of GPIU in university freshmen.
Growth models, random matrices and Painlevé transcendents

The Hammersley process relates to the statistical properties of the maximum length of all up/right paths connecting random points of a given density in the unit square from (0, 0) to (1, 1). This process can also be interpreted in terms of the height of the polynuclear growth model, or the length of the longest increasing subsequence in a random permutation. The cumulative distribution of the longest path length can be written in terms of an average over the unitary group. Versions of the Hammersley process in which the points are constrained to have certain symmetries of the square allow similar formulae. The derivation of these formulae is reviewed. Generalizing the original model to have point sources along two boundaries of the square, and appropriately scaling the parameters gives a model in the Kardar–Parisi–Zhang universality class. Following works of Baik and Rains, and Prahofer and Spohn, we review the calculation of the scaled cumulative distribution, in which a particular Painleve II transcendent plays a prominent role.

Robust Tracking Control of a Three-DOF Planar Under-actuated Manipulator

A manipulator with free joints is a class of under-actuated mechanisms. Control of such systems is one of major topics in robotics and control engineering. In this paper, we develop a nonlinear feedback controller to force a three-dof planar under-actuated manipulator affected by smooth, bounded uncertainties to globally asymptotically track a reference trajectory. This under-actuated manipulator moving in a horizontal plane has two prismatic actuated joints and one revolute free joint. The control development is based on some coordinate transformations, Lyapunov's direct method and popular integrator backstepping technique. Numerical simulations are presented that demonstrate the effectiveness of the controller.
Improved Sport Activity Recognition using Spatio-temporal Context

Activity recognition in sport is an attractive field for computer vision research. Game, player and team analysis are of great interest and research topics within this field emerge with the goal of automated analysis. As the execution of same activities differs between players and activities cannot be modeled by local description alone, additional information is needed. Inspired by the concept of group context ([Choi11], [Lan12], [Zhu13]), we employ contextual information to support activity recognition. Compared to other sport activity recognition systems e.g. proposed by [Bialkowski13], we focus on single player activities rather than on general team activities.
Are Hubble Deep Field Galaxy Counts Whole Numbers?

The Hubble Deep Field (HDF) offers the best view to date of the optical sky at faint magnitudes and small angular scales. Early reports suggested that faint source counts continue to rise to the completeness limit of the data, which implies a very large number of galaxies. In this Letter, we use the two-point angular correlation function and number-magnitude relation of sources within the HDF in order to assess their nature. We find that the correlation peaks between 0. ″25 and 0. ″4 with amplitude of 2 or greater and is much higher for the smallest objects. This angular scale corresponds to physical scales of order 1 kpc for redshifts z ≳ 1. The correlation must therefore derive from objects with subgalactic separations. At faint magnitudes, the counts satisfy the relation number ∝1/flux, which is expected for images that are subdivisions of larger ones. Several explanations for these observed correlations are possible, but a conservative explanation can suffice to produce our results. Since high-redshift space (z ≳ 0.5) dominates the volume of the sample, observational redshift effects are important. Rest-frame ultraviolet radiation appears in the HDF's visible and near-UV bands, and surface brightness dimming enhances the relative brightness of unresolved objects versus resolved objects. Both work to increase the prominence of compact star-forming regions over diffuse stellar populations. Thus, a “normal” gas-rich galaxy at high redshift can appear clumpy and asymmetric in the visible bands. For sufficiently faint and distant objects, the compact star-forming regions in such galaxies peak above undetectable diffuse stellar backgrounds. Our results do not exclude asymmetric formation or fragmentation scenarios.
