A deep ATCA 20 cm radio survey of the AKARI Deep Field South near the South Ecliptic Pole

The results of a deep radio survey at 20 cm wavelength are reported for a region containing the AKARI Deep Field South (ADF-S) near the South Ecliptic Pole (SEP), using the Australia Telescope Compact Array (ATCA). The survey (hereafter referred to as the ATCA-ADFS survey) has 1σ detection limits ranging from 18.7 to 50 μJy beam−1 over an area of ∼1.1 deg2, and ∼2.5 deg2 to lower sensitivity. The observations, data reduction and source count analysis are presented along with a description of the overall scientific objectives, and a catalogue containing 530 radio sources detected with a resolution of 6.2 × 4.9 arcsec. The derived differential source counts show a pronounced excess of sources fainter than ∼1 mJy, consistent with an emerging population of star-forming galaxies. Cross-correlating the radio with AKARI sources and archival data we find 95 cross-matches, with most galaxies having optical R-magnitudes in the range 18–24 mag, similar to that found in other optical deep field identifications, and 52 components lying within 1 arcsec of a radio position in at least one further catalogue (either IR or optical). We have reported redshifts for a sub-sample of our catalogue finding that they vary between galaxies in the local Universe and those having redshifts of up to 0.825. Associating the radio sources with the Spitzer catalogue at 24 μm, we find 173 matches within one Spitzer pixel, of which a small sample of the identifications are clearly radio loud compared to the bulk of the galaxies. The radio luminosity plot and a colour–colour analysis suggest that the majority of the radio sources are in fact luminous star-forming galaxies rather than radio-loud active galactic nuclei (AGN). There are additionally five cross-matches between the Atacama Submillimetre Telescope Experiment (ASTE) or the Balloon-borne Large Aperture Submillimetre Telescope (BLAST) galaxies and radio sources from this survey, two of which are also detected at 90 μm, and 41 cross-matches with submillimetre sources detected in the Herschel Multi-tiered Extragalactic Survey (HerMES) Public Data release.
A component-based open hypermedia approach to integrating structure services

Abstract In this paper, we consider the issue of integrating different structure services within a component-based open hypermedia system. We do so by considering the task of collaborative editing, which calls for a variety of different structures traditionally supplied by different structure services. We discuss the nature of collaborative editing and how it can be supported by a combination of spatial and navigational hypermedia services. We then present a component-based open hypermedia system architecture and describe various methods of integrating different structure services provided within such an architecture. We show the advantages of integration within a component-based framework over other means of integration, highlighting some of the main advantages of the component-based approach to open hypermedia system design and implementation.
Visualizing document authorship using n-grams and latent semantic indexing

An approach to visualizing authorship and writing style of free-form text documents is described. This approach uses n-grams and latent semantic indexing (LSI) to cluster documents according to usage patterns of related n-gram “terms”. Latent semantic indexing distributes documents nnd terms into a relatively low-dimensional space, which can be viwcd graphically using various visualization techniques.

Addressing Gifted Identification Equity through Alternatives: Assessing Creativity using an Authentic Performance Task

A great disparity exists between White and minority gifted student identification in states such as Georgia (McBee, 2010). To address equity issues in gifted creativity identification, Georgia teachers need a readily available, easy-to-use, and cost-effective creativity assessment alternative that conforms to the 2012 Georgia Department of Education (GADoE) gifted identification rule. The GADoE encouraged Georgia school districts in 2012 to include the use of products and/or performance tasks as part of the multiple criteria gifted screening process for creativity (Georgia Department of Education, 2014), but little guidance and no financial support was provided. The purpose of this participatory mixed methods action research study (PMARS) was to determine the effectiveness of a newly developed creativity performance task assessment in the gifted screening process compared to the traditional structured creativity assessment titled Profiles of Creative Abilities (PCA). The researcher used subjectivism as the research epistemology and a critical inquiry theoretical perspective to frame the research study. The researcher used a criterion purposive sample of 20 elementary students who were recommended for gifted screening and reflected the school district demographics. The students from one small urban school district completed a new authentic creativity performance task, which the researcher and another gifted specialist developed. The researcher trained gifted teachers from five elementary schools to implement the AW but neither result was significant. All the teachers who participated in the interview held a positive perception of the A&W Buttons Creativity Performance Task.

Top-down mass spectrometry of a 29-kDa protein for characterization of any posttranslational modification to within one residue

A mass difference between the measured molecular weight of a protein and that of its DNA-predicted sequence indicates sequence errors and/or posttranslational modifications. In the top-down mass spectrometry approach, the measured molecular ion is dissociated, and these fragment masses are matched against those predicted from the protein sequence to restrict the locations of the errors/modifications. The proportion of the ion's interresidue bonds that are cleaved determines the specificity of such locations; previously, ubiquitin (76 residues) was the largest for which all such bonds were dissociated. Now, cleavages are achieved for carbonic anhydrase at 250 of the 258 interresidue locations. Cleavages of three spectra would define posttranslational modifications at 235 residues to within one residue. For 24 of the 34 possible phosphorylation sites, the cleavages of one spectrum would delineate exactly all −PO3H substitutions. This result has been achieved with electron-capture dissociation by minimizing the further cleavage of primary product ions and by denaturing the tertiary noncovalent bonding of the molecular ions under a variety of conditions.
Outside-In , Inside-Out : Two Methods of Generating Spatial Certainty Maps

Problems with standard Boolean maps produced through subjective interpretation of a phenomenon (i.e., forest or soils maps) are discussed and two alternatives based on spatial certainty are presented and discussed. One requires multiple interpretations of the phenomenon in order to construct a library of spatial uncertainties; such an Uncertainty Library can be used subsequently to estimate error across cartographic boundaries. The other requires interpreters/cartographers to identify only those map elements which are “100% certain. ” A spatial interpolation algorithm is subsequently applied to this information to “fill in the gaps” with certainty information for each map type. Both methods have advantages and disadvantages relative to standard Boolean maps and also to each other. These are discussed in general terms and also through the presentation of specific examples. It is concluded that though uncertainty-based cartographic representations provide more flexibility than do conventional Boolean maps, the construction of the former is not without its prob-
Stress-related peptides in suicide attempters

A suicide attempt is the best known predictor of completed suicide. It has long been assumed that most suicide attempts are the results of stress. The aim of this thesis was to examine some stress related peptides and their relations to the hypothalamic pituitary adrenal (HPA) axis, diagnoses and temperament in a heterogeneous group of suicide attempters shortly after a suicide attempt and at follow up. As compared with healthy controls, the suicide attempters had increased pre- and postdexamethasone cortisol levels. They also had increased plasma delta sleep-inducing peptide (DSIP) and decreased plasma neuropeptide Y (NPY) and corticotrophin releasing hormone (CRH) in plasma. The most deviant DSIP levels were seen in major depressive disorder (MDD) patients and in patients who had attempted suicide previously (repeaters). Repeaters also showed the lowest plasma NPY levels. Furthermore, the results suggested an association between plasma NPY on the one hand and psychasthenia and irritability on the other. CRH concentrations in cerebrospinal fluid (CSF) were continuously low in the patients, whereas CSF somatostatin increased along with clinical improvement. These findings are in contrast with the low DSIP, high NPY and CRH in plasma previously noted in MDD patients by others. They are also in contrast with high CSF CRH levels which normally decrease with recovery from MDD. Our conclusion is that the stress experienced by patients with a recent suicide attempt have alterations in the stress system, which may be somewhat different from the stress system reactions seen in, e.g. general MDD patients.
Development of a semi self-contained wall climbing robot with scanning type suction cups

A semi self-contained wall climbing robot with scanning type suction cups is developed and rested. This robot has two vacuum pumps on it. The robot is connected to the equipment on the ground only through the electric power cables and information cables. From the experimental results, the robot can walk around on walls, clear steps, and stick on cracks and gaps. The walking speed attains 138 cm/min, which is 59% faster than the wall climbing robot I with tubes connected to the external vacuum pump on the ground. These experimental results show higher possibility towards the development of a complete self-contained wall climbing robot by putting a battery and a CPU on the robot.
Efficient High-Dimensional, Edge-Aware Filtering

Traditional computer graphics filters are agnostic to the concept of objects and the transition between objects (edges), but image filters need to take edges into account in order to produce high-quality, artifact-free, beautifully formed images. Eduardo S.L. Gastal's dissertation focuses on efficient algorithms for performing edge-aware image and video filtering. The techniques he describes here leverage the known relationship between edge-aware filtering and high-dimensional spaces and are capable of achieving real-time performance in high-resolution data.
Optical fiber system for real-time Fourier transformation of nanosecond-long broadband microwave waveforms

We experimentally achieve microwave dispersions approaching 24ns/GHz (equivalent to the dispersion of ∼185,000-km of standard single-mode fiber) using a fiber-optic incoherent processing setup. The scheme is used for real-time Fourier transformation of nanosecond-long microwave waveforms with bandwidths over 20 GHz.
catena-Poly[[[pyridinecopper(II)]-(μ-2-oxidonaphthalene-1-carbaldehyde picolinoylhydrazonato)-[pyridinecopper(II)]-μ-sulfato] diethyl ether hemisolvate]

The title compound, {[Cu2(C17H11N3O)(SO4)(C5H5N)2]·0.5C4H10O}n, was synthesized by the reaction of 2-hydroxy-1-naphthylaldehyde-2-pyridinecarboxylhydrazone with copper sulfonate. A one-dimensional polymer was obtained via self-assembly. Each Cu ion is located in a distorted square-pyramidal coordination environment, with one Cu ion coordinated by two N and three O atoms, while the other links to two O and three N atoms. In the crystal, weak intermolecular C—H⋯O interactions connect the chains into a two-dimensional network.
Modeling Behaviors of Interactive Objects for Real-Time Virtual Environments

Real-time 3D graphics are being extensively used to build interactive virtual environments for a number of different applications. In many situations, virtual objects are required to exhibit complex behaviors and the use of a versatile behavioral programming methodology is required. This paper presents a feature modeling approach to define behavioral information of virtual objects, giving special attention to their capabilities of interaction with virtual human actors. The proposed method is based on a complete definition and representation of interactive objects, which are called smart objects. This representation is based on the description of interaction features: parts, movements, graspable sites, functionalities, purposes, etc., including a behavioral automata based on scripts and graphical state machines.
Recognition of handprinted digits using optimal bounded error matching

A system for recognizing handprinted digits using optimal bounded error matching is described. Bounded error matching is already in common use in general-purpose 2D and 3D visual object recognition and can cope with clutter, occlusions, and noise, important issues also in OCR. The results presented demonstrate that the same techniques achieve high recognition rates (up to 99.2%) on a real-world handprinted digit recognition task (the NIST database of hand-printed census forms and the CEDAR database of digits extracted from US mail ZIP codes). As part of the system, a post-processing step for k-nearest neighbor classifiers based on decision trees is described that can be used (in place of the usual heuristic methods) for setting thresholds and that improves recognition rates significantly. <<ETX>>
Improved Detection of Differentially Expressed Genes Through Incorporation of Gene Locations

Summary In determining differential expression in cDNA microarray experiments, the expression level of an individual gene is usually assumed to be independent of the expression levels of other genes, but many recent studies have shown that a gene's expression level tends to be similar to that of its neighbors on a chromosome, and differentially expressed (DE) genes are likely to form clusters of similar transcriptional activity along the chromosome. When modeled as a one‐dimensional spatial series, the expression level of genes on the same chromosome frequently exhibit significant spatial correlation, reflecting spatial patterns in transcription. By modeling these spatial correlations, we can obtain improved estimates of transcript levels. Here, we demonstrate the existence of spatial correlations in transcriptional activity in the Escherichia coli (E. coli) chromosome across more than 50 experimental conditions. Based on this finding, we propose a hierarchical Bayesian model that borrows information from neighboring genes to improve the estimation of the expression level of a given gene and hence the detection of DE genes. Furthermore, we extend the model to account for the circular structure of E. coli chromosome and the intergenetic distance between gene neighbors. The simulation studies and analysis of real data examples in E. coli and yeast Saccharomyces cerevisiae show that the proposed method outperforms the commonly used significant analysis of microarray (SAM) t‐statistic in detecting DE genes.
Statistically enhanced localization schemes for randomly deployed wireless sensor networks

We address the localization problem for semi-static, randomly deployed, wireless sensor networks. The influence of the underlying random topology is discussed, and based on it we derive a distance estimations function of the number of hops two nodes are separated by, and characterize the precision of these estimations. The results are applied to two well-known localization schemes (DVHop and DVDistance) and improvements in the positioning error of roughly 26% for the first algorithm and 20% for the second algorithm are obtained. The introduced overhead is kept at a minimum as the resulting protocols are simpler than the original ones and only density information needs to be broadcast to the nodes.
Prospective cohort study of lifetime physical activity and breast cancer survival

Few studies have examined the association between physical activity and disease outcomes in breast cancer survivors. Here, we report the association between lifetime total physical activity performed prior to diagnosis and disease outcomes in a population‐based sample of breast cancer survivors. A cohort of 1,231 women diagnosed with breast cancer between 1995 and 1997 was followed for a minimum of 8.3 years for any cancer progressions, recurrences and new primaries; and a minimum of 10.3 years for deaths. All treatment and follow‐up care received was abstracted from medical records. Data on physical activity including type (occupational, household, recreational) and dose (frequency, intensity and duration) performed during the entire lifetime until diagnosis were examined in Cox proportional hazards models as well as with cumulative incidence curves. An average of 126 MET‐hr/week were reported for total physical activity (of which 13.9, 46.9 and 65.3 MET‐hr/week were, respectively, for recreational, occupational and household activity). A decreased risk of breast cancer death and all deaths was observed among women in the highest versus the lowest quartiles of recreational activity (MET‐hr/week/year) (HR = 0.54, 95% CI = 0.36–0.79). Both moderate (0.56, 95% CI = 0.38–0.82) and vigorous intensity recreational activity (0.74, 95% CI = 0.56–0.98) decreased the risk of breast cancer death. Moderate intensity recreational activity decreased the risk of a recurrence, progression or new primary cancer (0.66, 95% CI = 0.48–0.91). No other association with breast cancer survival was observed for other types of physical activity. Prediagnosis recreational activity conferred a benefit for survival after breast cancer. Moderate intensity recreational activity was particularly protective. © 2008 Wiley‐Liss, Inc.
Correcting fallacies about educational and psychological testing

Standardized testing is used for diagnosis, selection, and achievement measurement by individuals in many fields, including psychology, education, employment, and professional credentialing. Its benefits are numerous, substantial, and scientifically proven. However, these benefits are not well articulated or well publicized.In their technical communications, measurement specialists are generally positive about the worth of standardized testing. Meanwhile, those who engage public debate, such as journalists and certain special interest groups, tend to be less scientifically informed and more negative about the value of testing. The contributors to this volume contend that most criticisms ignore readily accessible scientific evidence and have the unfortunate effect of discrediting the entire testing enterprise.Standardized testing bears the twin burden of controversy and complexity and is difficult for many to understand either dispassionately or technically. In response to this reality, Richard P. Phelps and a team of well-noted measurement specialists present this book as a platform where they: describe the current state of public debate about testing across fields; explain and refute the primary criticisms of testing; acknowledge the limitations and undesirable consequences of testing; provide suggestions for improving testing practices; and, present a vigorous defense of testing and practical vision for its promise and future.Those who are charged with translating the science of testing into public information and policy - including administrators, social scientists, test publishers, professors, and journalists who specialize in education and psychology - should find a wealth of usable information here with which to balance the debate.
CCL3 Enhances Antitumor Immune Priming in the Lymph Node via IFNγ with Dependency on Natural Killer Cells

Lymph node (LN) plays a critical role in tumor cell survival outside of the primary tumor sites and dictates overall clinical response in many tumor types (1, 2). Previously, we and others have demonstrated that CCL3 plays an essential role in orchestrating T cell—antigen-presenting cell (APC) encounters in the draining LN following vaccination, and such interactions enhance the magnitude of the memory T cell pool (3–5). In the current study, we investigate the cellular responses in the tumor-draining lymph nodes (TDLNs) of a CCL3-secreting CT26 colon tumor (L3TU) as compared to wild-type tumor (WTTU) during the priming phase of an antitumor response (≤10 days). In comparison to WTTU, inoculation of L3TU resulted in suppressed tumor growth, a phenomenon that is accompanied by altered in vivo inflammatory responses on several fronts. Autologous tumor-derived CCL3 (aCCL3) secretion by L3TU bolstered the recruitment of T- and B-lymphocytes, tissue-migratory CD103+ dendritic cells (DCs), and CD49b+ natural killer (NK) cells, resulting in significant increases in the differentiation and activation of multiple Interferon-gamma (IFNγ)-producing leukocytes in the TDLN. During this early phase of immune priming, NK cells constitute the major producers of IFNγ in the TDLN. CCL3 also enhances CD8+ T cell proliferation and differentiation by augmenting DC capacity to drive T cell activation in the TDLN. Our results revealed that CCL3-dependent IFNγ production and CCL3-induced DC maturation drive the priming of effective antitumor immunity in the TDLN.
Modeling and steering of a novel actuated-tip needle through a soft-tissue simulant using Fiber Bragg Grating sensors

Needle insertions are common during surgical procedures. Accurately delivering the needle at a specific location in the human body is of importance for the clinical outcome of the procedure. Studies have already shown that robotically inserting traditional needles with a bevel tip can improve targeting accuracy. However, steering of such needles requires spinning the needle, which may lead to additional tissue damage. Therefore, we propose a novel design consisting of a flexible needle with a tendon-driven actuated-tip. Changing the orientation of the actuated-tip allows to control the steering direction of the needle and the amount of deflection. We derive the kinematic model which describes the needle path given the actuated-tip orientation based on nonholonomic kinematics. We present a method for steering the needle towards a target location in soft tissue. This method incorporates online parameter estimation in order to adapt for changes in tissue stiffness. Needle insertion experiments are performed in soft-tissue simulants, made from porcine gelatin. Needle tip pose is measured during insertion using Fiber Bragg Grating (FBG) based shape reconstruction. Results show that the needle can be steered towards targets located at 20 mm from the initial insertion axis, at a depth of 100 mm with a mean targeting error of 2.02 mm.
