On improved processor allocation in 2D mesh-based multicomputers: controlled splitting of parallel requests

Fragmentation can significantly limit the performance of mesh-based multicomputer systems. The adaptive non-contiguous allocation (ANCA) strategy solves the problem of fragmentation by allowing parallel jobs to be allocated non-contiguously. This is done by splitting the frame requested by the parallel job in hand into two subframes of equal sizes at the longest dimension of the request. This may result in having internal fragmentation problem. To remedy this problem, the ANCA strategy uses bookkeeping to keep tracking idle nodes. In this paper, the ANCA strategy is revisited with a new implementation and with more exhaustive simulation-based evaluation. Further, the idea of preventing over-splitting or over-partitioning of parallel requests is studied with the ANCA algorithm. In the proposed implementation, over-partitioning is avoided by placing a limit to maximum number of non-contiguous blocks that can be assigned to any parallel job. This maximum number is referred to as the partitioning-bound. Our experimental results show that having this partitioning-bound parameter can make the ANCA allocation strategy flexible and tunable as it allows the allocator module to choose an optimal partitioning-bound value while allowing parallel jobs to be allocated early without having them over-partitioned. Our experimental results also showed that the ANCA allocation strategy could sustain higher system and communication loads compared to other non-contiguous allocation strategies, namely; the MBS and Paging allocation strategies.
Mapping Complicated Surfaces onto a Sphere

A method for mapping a closed, triangulated surface of genus 0 onto the unit sphere was developed using a parameterization based on spherical coordinates analogous to latitude and longitude combined with Mercator scaling. The algorithm was tested on 77 protein and DNA surfaces and produce correct (bijective) mappings. The mappings produce relatively uniform distortion, as judged by angular criteria, and by distribution of octant areas, thus facilitating the graphical analysis of these surfaces. An application to the analysis and comparison of electrostatic surface potentials in the active sites of three serine proteases is presented.
Maximizing the overlap of two planar convex sets under rigid motions

Given two compact convex sets P and Q in the plane, we compute an image of P under a rigid motion that approximately maximizes the overlap with Q. More precisely, for any ε > 0, we compute a rigid motion such that the area of overlap is at least 1 - ε times the maximum possible overlap. Our algorithm uses O(1/ε) extreme point and line intersection queries on P and Q, plus O((1/ε2) log(1/ε)) running time. If only translations are allowed, the extra running time reduces to O((1/ε) log(1/ε)). If P and Q are convex polygons with n vertices in total, the total running time is O((1/ε) log n + (1/ε2) log(1/ε)) for rigid motions and O((1/ε) log n + (1/ε) log(1/ε)) for translations.
On the Muchnik degrees of 2-dimensional subshifts of finite type

We apply some concepts and results from mathematical logic in order to obtain an apparently new counterexample in symbolic dynamics. Two sets are said to be Muchnik equivalent if any point of either set can be used as a Turing oracle to compute a point of the other set. The Muchnik degree of a set is its Muchnik equivalence class. There is an extensive recursion-theoretic literature on the lattice Pw of Muchnik degrees of nonempty, recursively closed subsets of the Cantor space. It is known that Pw contains many specific, interesting, Muchnik degrees related to various topics in the foundations of mathematics and the foundations of computer science. Moreover, the lattice-theoretical structure of Pw is fairly well understood. We prove that Pw consists precisely of the Muchnik degrees of 2-dimensional subshifts of finite type. We use this result to obtain an infinite collection of 2-dimensional subshifts of finite type which are, in a certain sense, mutually incompatible.
The long Galactic bar as seen by UKIDSS Galactic plane survey

Context. Over the past decade there have been a series of results supporting the hypothesis of the existence of a long thin bar in the Milky Way with a half-length of 4.5 kpc and a position angle of around 45°. This is apparently a very different structure from the triaxial bulge of the Galaxy, which is thicker and shorter and dominates the star counts at $|l| Aims. In this paper, we analyse the stellar distribution in the inner Galaxy to see if there is clear evidence for two triaxial or bar-like structures in the Milky Way. Methods. By using the red-clump population as a tracer of Galactic structure, we determine the apparent morphology of the inner Galaxy. Deeper and higher spatial-resolution near infrared photometry from the UKIDSS Galactic plane survey allows us to use in-plane data even at the innermost Galactic longitudes, a region where the source confusion is a dominant effect that makes it impossible to use other databases, such as 2MASS or TCS-CAIN. Results. We show that results previously obtained with the red-clump giants are confirmed with the in-plane data from UKIDSS GPS. There are two different structures coexisting in the inner Galactic plane: one with a position angle of $23\fdg 60 \pm 2\fdg 19$ that can be traced from the Galactic centre up to ~10° (the Galactic bulge), and other with a larger position angle of $42 \fdg 44 \pm 2\fdg 14$, that ends around $l=28^\circ$ (the long Galactic bar).
Informational friend recommendation in social media

It is well recognized that users rely on social media (e.g. Twitter or Digg) to fulfill two common needs (i.e. social need and informational need) that is to keep in touch with their friends in the real world and to have access to information they are interested in. Traditional friend recommendation methods in social media mainly focus on a user's social need, but seldom address their informational need (i.e. suggesting friends that can provide information one may be interested in but have not been able to obtain so far). In this paper, we propose to recommend friends according to the informational utility, which stands for the degree to which a friend satisfies the target user's unfulfilled informational need, called informational friend recommendation. In order to capture users' informational need, we view a post in social media as an item and utilize collaborative filtering techniques to predict the rating for each post. The candidate friends are then ranked according to their informational utility for recommendation. In addition, we also show how to further consider diversity in such recommendations. Experiments on benchmark datasets demonstrate that our approach can significantly outperform the traditional friend recommendation methods under informational evaluation measures.
Data mining method of evaluating classifier prediction accuracy in retinal data

The research in recent years emphasizes the application of computational techniques in the field of ophthalmology. Diabetic Retinopathy, a retinal disease is the major cause of blindness. Early detection can help in treatment but regular screening for early detection has been a highly labor — and resource-intensive task. Hence automatic detection of the diseases through computational techniques would be a great social cause. In this paper, the classifiers used for the automatic detection of the disease are evaluated using the data mining methods. The prediction accuracy of all the classifiers, evaluated using various evaluation methods is presented. Our results show that a training accuracy of 100% can be achieved by a few classifiers and a prediction accuracy of 76.67%.
The Relation Between Topological Ordering and Adjacency Matrix in Digraphs

In this paper the properties of node-node adjacency matrix in acyclic digraphs are considered. It is shown that topological ordering and node-node adjacency matrix are closely related. In fact, rst the one to one correspondence between upper triangularity of node-node adjacency matrix and existence of directed cycles in digraphs is proved and then with this correspondence other properties of adjacency matrix in acyclic digraphs are presented.
''Blastocyst MHC'' Isoforms of the Proposed HLA-G Homolog, Ib MHC Includes Alternatively Spliced The Murine Family of Gut-Restricted Class

The gastrointestinal tract is populated by a multitude of specialized immune cells endowed with receptors for classical (class Ia) and nonclassical (class Ib) MHC proteins. To identify class I products that engage these receptors and impact immunity/tolerance, we studied gut-transcribed class Ib loci and their polymorphism in inbred, outbred, and wild-derived mice. Intestinal tissues enriched in epithelial cells contained abundant transcripts of ubiquitously expressed and preferentially gut-restricted Q and T class I loci. The latter category included the “blastocyst Mhc ” gene, H2-Bl , and its putative paralog, Tw5 . Expression of H2-Bl was previously detected only at the maternal/fetal interface, where it was proposed to induce immune tolerance via interactions with CD94/NKG2A receptors. Analysis of coding region polymorphism performed here revealed two major alleles of H2-Bl with conserved residues at positions critical for class I protein folding and peptide binding. Both divergent alleles are maintained in outbred and wild mice under selection for fecundity and pathogen resistance. Surprisingly, we found that alternative splicing of H2-Bl mRNA in gut tissues is prevalent and allele-speciﬁc. It leads to strain-dependent expression of diverse repertoires of canonical and noncanonical transcripts that may give rise to distinct ligands for intestinal NK cell, T cell, and/or intraepithelial lymphocyte receptors.

Lysosomal abnormalities in hereditary spastic paraplegia types SPG15 and SPG11

Hereditary spastic paraplegias (HSPs) are among the most genetically diverse inherited neurological disorders, with over 70 disease loci identified (SPG1‐71) to date. SPG15 and SPG11 are clinically similar, autosomal recessive disorders characterized by progressive spastic paraplegia along with thin corpus callosum, white matter abnormalities, cognitive impairment, and ophthalmologic abnormalities. Furthermore, both have been linked to early‐onset parkinsonism.
A battery-less, wireless mote for scavenging wireless power at UHF (470–570 MHz) frequencies

In this paper, a novel power scavenging mote to harness wireless power in the UHF frequencies between 470 and 570 MHz is presented. A broadband monopole antenna prototype inkjet printed on a paper based substrate is used transduce the incident wireless power from its Electromagnetic wave form to a RF AC signal. A conjugately matched voltage multiplier and RF transformer are used to rectify and store the RF input power in a low leakage capacitor for powering on a microcontroller unit and wireless transceiver end-device thereby making the entire operation of this mote battery-less.
Fluoropyrimidine sensitivity of human MCF-7 breast cancer cells stably transfected with human uridinehosphorylase

The relationship between uridine phosphorylase (UP) expression level in cancer cells and the tumour sensitivity to fluoropyrimidines is unclear. In this study, we found that UP overexpression by gene transfer, and the subsequent efficient metabolic activation of 5-fluorouracil (5-FU) by the ribonucleotide pathway, does not increase the fluoropyrimidine sensitivity of MCF-7 human cancer cells. © 2001 Cancer Research Campaign http://www.bjcancer. com
Making connections: A process model of organizational identification

Organizational identification is conventionally defined as a sense of oneness. Yet this is static and inhibits a process view of identification, in which organizational identity is continuously adjusted. Most studies of organizational identification are of members and not stakeholders, despite evidence that suggests that stakeholders have a significant role and that organizational identity and image are reciprocally connected. We ask the question: how is organizational identification discursively constructed? We suggest that stakeholders play a key role in organizational identification processes. The forward movement of the process, from Performative to Instrumental to Interactional to Reciprocal, is one of reinforcement in which soft power enrols a virtuous circle of willing support. The backward movement of the process, from Reciprocal to Interactional to Instrumental to Performative, is one of functional justification involving hard power as coercion by communicating the organization’s expectations to the individual.
Singing synthesis with an evolved physical model

A two-dimensional physical model of the human vocal tract is described. Such a system promises increased realism and control in the synthesis of both speech and singing. However, the parameters describing the shape of the vocal tract while in use are not easily obtained, even using medical imaging techniques, so instead a genetic algorithm (GA) is applied to the model to find an appropriate configuration. Realistic sounds are produced by this method. Analysis of these, and the reliability of the technique (convergence properties) is provided
The Professional Mind-Set of City Managers: Implications for Public Administration

We develop a theoretical model of city manager professionalism addressing professional guidance and commitment, and four public service values: ethical solutions, neutral competence, political responsiveness, and political solutions. We tested these professionalism values on a national survey sample of city managers in the United States. Using structural equation modeling, we found evidence that professionalism acted directly on reported ethical behavior, and ethical behavior indirectly explained political responsiveness positively and political solutions negatively through neutral competence. Our analysis supports arguments that public service professionalization is possible and clarifies the pathways toward this important goal. Our study focuses on understanding how involvement in professional associations and activities relates to city manager perceptions of their own values and competence.
Clumpy tori around active galactic nuclei

We discuss the question whether the matter in dusty tori around active galactic nuclei has a smooth or a clumpy structure. Nenkova et al. (2002, ApJ, 570, L9) have argued that the lack of emission feature in the SEDs of type 1 AGN galaxies combined with a clear absorption feature in type 2 AGN can be explained if the circumnuclear dust is distributed in discrete clumps. Our aim is to verify this. We use multi-dimensional radiative transfer models of smooth and clumpy tori, and compare the SEDs of equivalent smooth and clumpy models. We find that the 10 µm emission feature of the clumpy models, when seen almost face-on, is not appreciably reduced compared to the equivalent smooth models. Some of the clumpy models have a weak or even absent 10 µm feature, but so do some of the smooth models. On the whole the SEDs of clumpy and smooth tori are similar, but some details are different. The absorption feature seen at edge-on inclinations appears to be less deep in the clumpy models than in the smooth models, and the average flux in the near-infrared regime is stronger in the clumpy models. Moreover, at these inclinations the clumpy models have a slightly wider SED. Whether these differences are unique enough to be used as a diagnostic for clumpiness of AGN tori is not yet clear.
Tolerable Deviance and How it Applies to Cyberbullying

ABSTRACT As a result of the modern youth culture’s reliance on technology and instant communications, mainly through social media platforms, bullying has transitioned to the online domain where cyberbullying has emerged. Among youth, cyberbullying can be viewed as a type of tolerable deviancy where youth often do not question the deviant nature of their online behaviors. This research explores the creation of the scale of deviancy as developed through a qualitative popular film analysis where low-, moderate-, and high-level deviancy characterize various cyberbullying behaviors and captures the essence of the escalation of harm faced by cyber victim(s).
The relevant factors in the Teaching-Learning Process of Design of Experiments

Experimentation in engineering is an active experience full of excitements in order to pursuit new findings or to find new answers to certain hypothes is previously stated. The same spirit should exist in the Teaching Learning Process of Design of Experiments (DOE): active, enthusiastic, dynamic and systemic. This paper resumes the findings of an experiment aimed to discover the relevant factors in making efficient t he Teaching Learning Process in a course of Design of Experiments in a bachelor curriculum. Using the statistical design of experiment methodol ogy, a 2k-1 experiment was conducted (a half fraction of f our factors, each with two levels and a IV resolution) in a course of 40 students arranged in 8 sub-groups. The project was developed using a six steps methodology : a) defining the problem, b) selecting the proper varia bles, c) designing the experiment, d) running the experiment, e) analyzing the results and f) making conclusions and recommendations. The results was a mathematical model that expresses the desired output variable Y as a function of the next relevant factors in a Teaching-Learning process: 1 ) Use active didactic strategies (Problem Based Learning) , 2) Deliver relatively high homework, and 3) Give opportune feed back to the individual student work performance. Controlling these elements the learning process can be successfully performed.
6DOF pose estimation of objects for robotic manipulation. A review of different options

6DOF pose estimation of objects in robotics is nowadays an active field of research under different approaches. The solution of this problem depends directly on many aspects, such as the geometry of the object to be located, the flexibility of the solution needed, or the 3D sensors used. Reaching a robust and reliable solution to this problem is essential, being this the first step in present research in industrial robotics, where advanced manipulation and identification of complex objects is fundamental. This paper presents different results obtained solving the 6DOF pose estimation problem, using different software libraries and the Microsoft Kinect as 3D acquisition system to capture the scene.
Evaluation of Model Comparison for Delta-Compression in Model Persistence

Model-based software engineering is applied to more and more complex software systems. As a result, larger and larger models with longer and longer histories have to be maintained and persisted. Already, a lot of research eﬀorts went into model versioning, comparison, and repositories. Existing strategies either record and persist changes (change-based repositories, e.g. EMF-Store) or relay on existing text-based version control systems to persist whole model revisions (state-based repositories). Both approaches have advantages and disadvantages. We suggest a hybrid approach that infers changes via comparison to persist delta-compressed model states. Our hypothesis is that delta-compression requires a trade-oﬀ between comparison quality and execution time. Existing model comparison frameworks are tailored for comparison quality and not necessarily execution time performance. Therefore, we evaluate and compare traditional line-based comparison, an existing model comparison framework (EMF-Compare), and our own framework (EMF-Compress). We reverse engineered the Eclipse code-base and it’s history with MoDisco to create a large corpus of evolving example models for our experiments.
Deficiency in p53 is required for doxorubicin induced transcriptional activation of NF-κB target genes in human breast cancer

NF-κB has been linked to doxorubicin resistance in breast cancer patients. NF-κB nuclear translocation and DNA binding in doxorubicin treated-breast cancer cells have been extensively examined; however its functional relevance at transcriptional level on NF-κB -dependent genes and the biological consequences are unclear. We studied NF-κB -dependent gene expression induced by doxorubicin in breast cancer cells and fresh human cancer specimens with different genetic backgrounds focusing on their p53 status. NF-κB -dependent signature of doxorubicin was identified by gene expression microarrays in breast cancer cells treated with doxorubicin and the IKKβ-inhibitor MLN120B, and confirmed ex vivo in human cancer samples. The association with p53 was functionally validated. Finally, NF-κB activation and p53 status was determined in a cohort of breast cancer patients treated with adjuvant doxorubicin-based chemotherapy. Doxorubicin treatment in the p53-mutated MDA-MB-231 cells resulted in NF NF-κB driven-gene transcription signature. Modulation of genes related with invasion, metastasis and chemoresistance (ICAM-1, CXCL1, TNFAIP3, IL8) were confirmed in additional doxorubicin-treated cell lines and fresh primary human breast tumors. In both systems, p53-defcient background correlated with the activation of the NF-κB -dependent signature. Furthermore, restoration of p53WT in the mutant p53 MDA-MB-231 cells impaired NF-κB driven transcription induced by doxorubicin. Moreover, a p53 deficient background and nuclear NF-κB /p65 in breast cancer patients correlated with reduced disease free-survival. This study supports that p53 deficiency is necessary for a doxorubicin driven NF-κB -response that limits doxorubicin cytotoxicity in breast cancer and is linked to an aggressive clinical behavior.
