A first analysis of MIMO communication as a basis for low power wireless

A screen grid voltage or a focus voltage for a cathode ray tube is controlled via a digital-to-analog converter. The voltage variation range of the screen grid or focus voltage that can be obtained for the entire variation range of an output signal of the digital-to-analog converter is not significantly larger than that required for the type of cathode ray tube that is utilized.
Development and Psychometric Evaluation of the Paternal Involvement With Infants Scale

A growing body of research reflects the need to focus on fathers’ involvement with their infants. For many years, this was assessed by such domains as cohabitation, financial contributions, and/or asking mothers to rate the quality and quantity of the father’s interactions with their children. Current scholarship has designated father involvement as a multifaceted construct, reflective of changing gender roles of men and fathers in the United States. However, there exists no self-report instrument of father’s involvement with their infants that adequately measures the multifaceted components of the construct. The current project aims to develop a psychometrically sound, theoretically grounded instrument of father involvement. The Paternal Involvement With Infants Scale (PIWIS) is a self-report instrument that assesses a variety of ways in which new fathers are involved with their infant. In Sample 1, fathers of infants (N = 456) completed the PIWIS. Exploratory factor analyses (n = 250) and confirmatory factor analyses (n = 206) supported a 5-factor solution including positive engagement, indirect care, frustration, warmth and attunement, and control and process subscales. Sample 2 (N = 57) participants completed the PIWIS 4 weeks apart in order to provide test–retest reliability scores (r’s > .51). Concurrent evidence of validity was established via significant positive correlations with theoretically related measures of social support, paternal engagement, infant care self-efficacy, parental alliance, parental satisfaction, and overall life satisfaction as well as negative correlations with gender role conflict and depression. Clinical implications and implications for future research are discussed.
Shock capturing and related numerical methods in computational fluid dynamics.

Some developments and efforts in designing and analyzing shock capturing algorithms and related numerical methods in computational fluid dynamics are reviewed. The importance of numerical viscosity in shock capturing algorithms is analyzed; the convergence and stability of some shock capturing algorithms are presented; the role of shock capturing algorithms in a mathematical existence theory is exhibited, especially for the compressible Euler equations for gas dynamics in one dimension and in multi-dimensions with spherical symmetry. Applications of shock capturing ideas to the compressible Navier-Stokes equations are also discussed.
FAM46 proteins are novel eukaryotic non-canonical poly(A) polymerases

FAM46 proteins, encoded in all known animal genomes, belong to the nucleotidyltransferase (NTase) fold superfamily. All four human FAM46 paralogs (FAM46A, FAM46B, FAM46C, FAM46D) are thought to be involved in several diseases, with FAM46C reported as a causal driver of multiple myeloma; however, their exact functions remain unknown. By using a combination of various bioinformatics analyses (e.g. domain architecture, cellular localization) and exhaustive literature and database searches (e.g. expression profiles, protein interactors), we classified FAM46 proteins as active non-canonical poly(A) polymerases, which modify cytosolic and/or nuclear RNA 3′ ends. These proteins may thus regulate gene expression and probably play a critical role during cell differentiation. A detailed analysis of sequence and structure diversity of known NTases possessing PAP/OAS1 SBD domain, combined with state-of-the-art comparative modelling, allowed us to identify potential active site residues responsible for catalysis and substrate binding. We also explored the role of single point mutations found in human cancers and propose that FAM46 genes may be involved in the development of other major malignancies including lung, colorectal, hepatocellular, head and neck, urothelial, endometrial and renal papillary carcinomas and melanoma. Identification of these novel enzymes taking part in RNA metabolism in eukaryotes may guide their further functional studies.
Validity as Research Praxis: A Study of Self-Reflection and Engagement in Qualitative Inquiry

This article continues explorations into the concept of validity by looking closely at the notion of praxis as it might be involved in establishing validity through the doing of qualitative inquiry. Departing from thinking of the qualitative researcher as an instrument to thinking of the engagement of the researcher in the research process as praxis-oriented, new ways of thinking about how validity is established intra-actively are articulated. I report on an in-depth qualitative interview study of nine Christian women talking about their faiths. Instead of focusing on the substantive findings of the article, I analyzed the researcher–participant interactions using the concept of praxis to articulate five distinct ways validity was established through the researching process. These findings challenge correspondence theories of truth as the basis for validity and, instead, engage in a dialogic, complex notion of truth-telling as the point of resonance for validity.

Multi-Hop Vehicular Broadcast (MHVB)

Inter-vehicular communications (IVCs) are now considered as a way to realize active safety, for example, by providing the position information of each other or the potential danger warning by wireless communications. We have worked on a flooding protocol over vehicular ad hoc networks (VANETs) to efficiently disseminate the information for the sake of active safety applications, such as the positions and the velocities of the vehicles. We propose a flooding protocol with (i) congestion detection algorithm which suppresses unnecessary packets due to vehicular congested traffic and (ii) Backfire algorithm which efficiently forwards the packet through the network by selecting the adequate receiver node based on the distance from the original node. In this paper, we show simulation results over NS2 (network simulator 2). They show that the proposed flooding protocol significantly improves the performance of data dissemination over VANETs
Survival of Suillus pungens and Amanita francheti ectomycorrhizal genets was rare or absent after a stand-replacing wildfire.

• We looked for evidence of mycelial survival by Suillus pungens and Amanita francheti following a stand-replacing wildfire. These species were selected because we had previously mapped and genotyped their fruiting bodies in the pre-fire forest. • Mycelial survival was investigated in two ways. First, we sampled seedlings in areas where these species had fruited abundantly before the fire, and second, we collected and genotyped mushrooms of S. pungens . • Neither species was detected on seedlings within the areas sampled, and A. francheti was not detected in any above- or below-ground samples after the fire. Genetic evidence from S. pungens revealed that post-fire genets were small and numerous, and none were found to be identical to the genets sampled prior to the fire. • From these results we conclude that A. francheti was not a common survivor or an early colonist of the post-fire forest, and that spores are the primary means by which S. pungens recolonized. If mycelial survival occurred in either species, it must have been relatively rare.
Energy release model of compaction band propagation

The elastic strain energy released per unit advance of a compaction band in an infinite layer of thickness h is used to identify and assess quantities relevant to propagation of isolated compaction bands observed in outcrop. If the elastic moduli of the band and the surrounding host material are similar and the band is much thinner than the layer, the energy released is simply σ+ξhεp where σ+ is the compressive stress far ahead of the band edge, ξh is the thickness of the band and εp is the uniaxial inelastic compactive strain in the band. Using representative values inferred from field data yields an energy release rate of 40 kJ/m2, which is roughly comparable with compaction energies inferred from axisymmetric compression tests on notched sandstone samples. This suggests that a critical value of the energy release rate may govern propagation, although the particular value is likely to depend on the rock type and details of the compaction process.
Development of affinity-based delivery of NGF from a chondroitin sulfate biomaterial

Chondroitin sulfate is a major component of the extracellular matrix in both the central and peripheral nervous systems. Chondroitin sulfate is upregulated at injury, thus methods to promote neurite extension through chondroitin sulfate-rich matrices and synthetic scaffolds are needed. We describe the use of both chondroitin sulfate and a novel chondroitin sulfate-binding peptide to control the release of nerve growth factor. Interestingly, the novel chondroitin sulfate-binding peptide enhances the controlled release properties of the chondroitin sulfate gels. While introduction of chondroitin sulfate into a scaffold inhibits primary cortical outgrowth, the combination of chondroitin sulfate, chondroitin sulfate-binding peptide and nerve growth factor promotes primary cortical neurite outgrowth in chondroitin sulfate gels.
Heterogeneity and aggregation

This survey covers recent solutions to aggregation problems in three application areas, consumer demand analysis, consumption growth and wealth, and labor participation and wages. Each area involves treatment of heterogeneity and nonlinearity at the individual level. Three types of heterogeneity are highlighted: heterogeneity in individual tastes, heterogeneity in income and wealth risks and heterogeneity in market participation. Work in each area is illustrated using results from empirical data. The overall aim is to show how concerns faced by empirical researchers regarding aggregation can be addressed.
Lateral error recovery for application-level multicast

We consider the delivery of reliable and streaming services using application-level multicast (ALM) by means of UDP, where packet loss has to be recovered via retransmission in a timely manner in order to offer high level of service. Since packets may be lost due to congestion, tree-reconfiguration or node failure, the traditional "vertical" recovery, whereby upstream nodes retransmit the lost packet is no longer effective. We therefore propose and investigate lateral error recovery (LER). In LER, hosts are divided into a number of planes, each of which forms an independent ALM tree. Since the correlation of error among the planes is likely to be low, a node can effectively recover its error "laterally" from nearby nodes in other planes. We employ the technique of global network positioning (GNP) to map the hosts into a coordinate space and identify a set of close neighbors for error recovery by constructing a Voronoi diagram for each plane. We present centralized and distributed algorithm on how to construct the Voronoi diagrams. Using Internet-like topologies, we show via simulations that our system achieves low overheads in terms of relative delay penalty and physical link stress. For reliable service, lateral recovery greatly reduces the average recovery time as compared with vertical recovery schemes. For streaming applications, LER achieves much lower residual loss rate under a certain deadline constraint.

Preschool pedagogy and its impact on preschoolers' attitudes toward learning

KAREN ANNETTE LOUNSBURY. Preschool pedagogy and its impact on preschoolers’ attitudes toward learning. (Under the direction of DR. KELLY M. ANDERSON) This qualitative study examined two preschool pedagogical approaches and the impact each had on students’ attitudes toward learning. One preschool used A Beka curriculum, which is a direct instruction pedagogy. The other preschool used Creative Curriculum, which is structured for children to learn through exploration and teacher scaffolding. A four year old boy and a four year old girl from each preschool were selected to participate. Four sources of data were collected: (a) observation of each participant, (b) a drawing completed by each participant, (c) an interview with each participant, and (d) the Learning Behavior Scale which was completed by both the participant’s parent and teacher. All four students expressed that school was hard, especially drawing and writing. Recommendations are for further research to be conducted on pedagogy and students’ attitudes toward learning in kindergarten as the pressures of a more academic curriculum are imposed upon young children, and the study be done at the beginning of the school year, midyear, and end of the school year.
Electron-impact excitation of neutral oxygen

Aims. Our goal was to calculate transition rates from ground and excited states in neutral oxygen atoms due to electron collisions for non-LTE modelling of oxygen in late-type stellar atmospheres, thus enabling the reliable interpretation of oxygen lines in stellar spectra. Methods. A 38-state R -matrix calculation in LS -coupling has been performed. Basis orbitals from the literature are adopted, and a large set of configurations are included to obtain good representations of the target wave functions. Rate coefficients are calculated by averaging over a Maxwellian velocity distribution. Results. Estimates for the cross sections and rate coefficients are presented for transitions between the seven lowest LS states of neutral oxygen. The cross sections for excitation from the ground state compare well with existing experimental and recent theoretical results.

Weighted reciprocity in human communication networks

In this paper we define a metric for reciprocity appropriate for weighted networks in order to investigate the distribution of reciprocity in a large-scale social network composed of billions of communication attempts across millions of actors. We find that relations in this network are characterized by much larger degrees of non-reciprocity than we would expect if persons kept only those relationships that exhibit balance. We point to two structural features of human communication behavior and relationship formation—the division of contacts into strong and weak ties and the tendency to form relationships with similar others—that either help or hinder the ability of persons to obtain balance in their relationships. We examine the extent to which deviations from reciprocity in the observed network are partially traceable to these characteristics.
Judging Time Intervals Using a Model of Perceptuo-Motor Control

Estimating a time interval and temporally coordinating movements in space are fundamental skills, but the relationships between these different forms of timing, and the neural processes that they incur, are not well understood. While different theories have been proposed to account for time perception, time estimation, and the temporal patterns of coordination, there are no general mechanisms which unify these various timing skills. This study considers whether a model of perceptuo-motor timing, the GUIDE, can also describe how certain judgements of elapsed time are made. To evaluate this, an equation for determining interval estimates was derived from the GUIDE model and tested in a task where participants had to throw a ball and estimate when it would hit the floor. The results showed that in accordance with the model, very accurate judgements could be made without vision (mean timing error 19.24 msec), and the model was a good predictor of skilled participants' estimate timing. It was concluded that since the GUIDE principle provides temporal information in a generic form, it could be a unitary process that links different forms of timing.
Simulating Organizational Change Triggered by a Changing Environment

Organizational modeling gains importance in the development of multi-agent systems, both for modeling and simulation of phenomena in social science and economics, as for developing complex systems to support, e.g., virtual enterprises. This paper contributes to these efforts an analysis and example formalizations and simulation of cause and effect of organizational change. Causes of change are categorized and related to internals within organizations via trees covering different aggregation levels. Furthermore, properties which should be satisfied by organizational change are identified and specified.
Bone Ingrowth to Ti Fibre Knit Block with High Deformability

ABSTRACT Objectives The objective of this study is to develop a Ti fibre knit block without sintering, and to evaluate its deformability and new bone formation in vivo. Material and Methods A Ti fibre with a diameter of 150 μm was knitted to fabricate a Ti mesh tube. The mesh tube was compressed in a metal mould to fabricate porous Ti fibre knit blocks with three different porosities of 88%, 69%, and 50%. The elastic modulus and deformability were evaluated using a compression test. The knit block was implanted into bone defects of a rabbit’s hind limb, and new bone formation was evaluated using micro computed tomography (micro-CT) analysis and histological analysis. Results The knit blocks with 88% porosity showed excellent deformability, indicating potential appropriateness for bone defect filling. Although the porosities of the knit block were different, they indicated similar elastic modulus smaller than 1 GPa. The elastic modulus after deformation increased linearly as the applied compression stress increased. The micro-CT analysis indicated that in the block with 50% porosity new bone filled nearly all of the pore volume four weeks after implantation. In contrast, in the block with 88% porosity, new bone filled less than half of the pore volume even 12 weeks after implantation. The histological analysis also indicated new bone formation in the block. Conclusions The titanium fibre knit block with high porosity is potentially appropriate for bone defect filling, indicating good bone ingrowth after porosity reduction with applied compression.
Some comments on the universal constant in DSR

Deformed Special Relativity is usually presented as a deformation of Special Relativity accommodating a new universal constant, the Planck mass, while respecting the relativity principle. In order to avoid some fundamental problems (e.g. soccer ball problem), we argue that we should switch point of view and consider instead the Newton constant G as the universal constant.
Spike train signatures of retinal ganglion cell types

The mammalian retina deconstructs the visual world using parallel neural channels, embodied in the morphological and physiological types of ganglion cells. We sought distinguishing features of each cell type in the temporal pattern of their spikes. As a first step, conventional physiological properties were used to cluster cells in eight types by a statistical analysis. We then adapted a method of P. Reinagel et al. (1999: J. Neurophysiol., 81, 2558–2569) to define epochs within the spike train of each cell. The spike trains of many cells were found to contain robust patterns that are defined by the (averaged) timing of successive interspike intervals in brief activity epochs. The patterns were robust across four different types of visual stimulus. Although the patterns are conserved in different visual environments, they do not prevent the cell from signaling the strength of its response to a particular stimulus, which is expressed in the number of spikes contained in each coding epoch. Clustering based on the spike train patterns alone showed that the spike train patterns correspond, in most but not all cases, to cell types pre‐defined by traditional criteria. That the congruence is less than perfect suggests that the typing of rabbit ganglion cells may need further refinement. Analysis of the spike train patterns may be useful in this regard and for distinguishing the many unidentified ganglion cell types that exist in other mammalian retinas.
Computer Arithmetic Preserving Hamming Distance of Operands in Operation Result

The traditional approach to fault tolerant computing involves replicating computation units and applying a majority vote operation on individual result bits. This approach, however, has several limitations; the most severe is the resource requirement. This paper presents a new method for fault tolerant computing where for a given error rate, the hamming distance between correct inputs and faulty inputs as well as the hamming distance between a correct result and a faulty result is preserved throughout processing thereby enabling correction of up to transient faults per computation cycle. The new method is compared and contrasted with current protection methods and its cost / performance is analyzed.
