A method to efficiently encode inter-view vectors in conditional replenishment algorithm

Conditional replenishment algorithm (CRA) was proposed to improve the quality of a hybrid 3DTV system with mixed resolution. Since CRA generates additional information which includes inter-view vectors, it is needed to efficiently encode the information. This paper proposes a method to apply differential pulse code modulation (DPCM) to the inter-view vectors so as to improve the coding efficiency of CRA.

Then, based on NI software-defined radio (SDR) platform, the RFID air interface protocol was realized through the communication between the reader emulator and tag emulator. This also lays a foundation for the conformance test of the RFID air interface protocol.
WOX11 and 12 Are Involved in the First-Step Cell Fate Transition during de Novo Root Organogenesis in Arabidopsis[W]

Adventitious roots and shoots can be regenerated from wounded or detached plant organs via de novo organogenesis. This study reveals the cellular and molecular framework of de novo root organogenesis from leaf explants of Arabidopsis thaliana and shows that auxin-induced WOX11 expression marks the first-step cell fate transition in this process. De novo organogenesis is a process through which wounded or detached plant tissues or organs regenerate adventitious roots and shoots. Plant hormones play key roles in de novo organogenesis, whereas the mechanism by which hormonal actions result in the first-step cell fate transition in the whole process is unknown. Using leaf explants of Arabidopsis thaliana, we show that the homeobox genes WUSCHEL RELATED HOMEOBOX11 (WOX11) and WOX12 are involved in de novo root organogenesis. WOX11 directly responds to a wounding-induced auxin maximum in and surrounding the procambium and acts redundantly with its homolog WOX12 to upregulate LATERAL ORGAN BOUNDARIES DOMAIN16 (LBD16) and LBD29, resulting in the first-step cell fate transition from a leaf procambium or its nearby parenchyma cell to a root founder cell. In addition, our results suggest that de novo root organogenesis and callus formation share a similar mechanism at initiation.
Polymorphisms in Base Excision Repair Genes Are Associated With Endometrial Cancer Risk Among Postmenopausal Japanese Women

Objectives Polymorphisms in base excision repair (BER) genes are associated with risk for several types of cancers but have not been studied with respect to endometrial cancer among Japanese women. Therefore, we conducted a case-control study to explore the association between polymorphisms in BER genes and the risk for endometrial cancer. Methods/Materials This study included a total of 91 postmenopausal subjects with endometrial cancer and 261 controls without cancer who visited the Aichi Cancer Center between 2001 and 2005. We focused on single nucleotide polymorphisms within coding regions of 5 BER genes (OGG1, MUTYH, XRCC1, APEX1, and PARP1). To assess lifestyle in the etiology of endometrial cancer, we used a self-administered questionnaire. Associations were evaluated using multivariate unconditional logistic regression models. We also assessed whether there were intergenic associations or an interaction with obesity. Results We observed a significant association between endometrial cancer risk and XRCC1 rs1799782 (C > T, Arg194Trp) and XRCC1 rs25487 (G > A, Arg399Gln). We uncovered a significant association between obesity (body mass index, ≥25) and rs25487. The XRCC1 polymorphisms were in complete linkage disequilibrium, and the XRCC1 haplotype TG associated significantly with endometrial cancer risk. The interaction between the CA haplotype and body mass index was marginally significant, whereas interaction between haplotype in XRCC1 and rs1136410 (PARP1) was not significant. Conclusions We found a significant association between endometrial cancer risk and XRCC1 polymorphisms and haplotype TG in postmenopausal Japanese women.
Blind source separation using multinode sparse representation

The blind source separation problem is concerned with extraction of the underlying source signals from a set of their linear mixtures, where the mixing matrix is unknown. It was discovered recently, that exploiting the sparsity of sources in their representation according to some signal dictionary, dramatically improves the quality of separation. It is especially useful in image processing problems, wherein signals possess strong spatial sparsity. We use multiscale transforms, such as wavelet or wavelet packets, to decompose signals into sets of local features with various degrees of sparsity. We use this intrinsic property for selecting the best (most sparse) subsets of features for further separation. Experiments with 1D signals and images demonstrate significant improvement of separation quality.
Development of highly roughened porous Au electrode with Pt nano-particle for electrochemical sensor applications

Highly roughened coral-like porous Au electrode with electroplated Pt nano-particles was newly developed and characterized. The porosity and window-pore size of the fabricated porous Au electrode were approximately 50 % and 100–300nm, respectively. The electroplated Pt nano-particle size was approximately 5–10nm. For miniaturized electrochemical and biochemical sensor applications, the fabricated Au-Pt nano-electrode was characterized in sulfuric acid and H2O2 solutions. It showed extremely large sensitivity of 0.166 mA/mM·cm2, excellent linearity of 0.989, and surface roughness factor of 488, which were the highest values in the previously reported ones.
Synapsin‐like Molecules in Aplysia punctata and Helix pomatia: Identification and Distribution in the Nervous System and During the Formation of Synaptic Contacts In Vitro

The distribution and biochemical features of the synapsin‐like peptides recognized in Aplysia and Helix by various antibodies directed against mammalian synapsins were studied. The peptides can be extracted at low pH and are digested by collagenase; further, they can be phosphorylated by both protein kinase A and Ca2+/calmodulin‐dependent protein kinase II. In the ganglia of both snails, they are associated with the soma of most neurons and with the neuropil; punctate immunostaining is present along the neurites. Using cocultures of a Helix serotoninergic neuron and of its target cell, we analysed the redistribution of the synapsin‐like peptides during the formation of active synaptic contacts. When the presynaptic neuron is plated in isolation, both synapsin and serotonin immunoreactivities are restricted to the distal axonal segments and to the growth cones; in the presence of the target, the formation of a chemical connection is accompanied by redistribution of the synapsin and serotonin immunoreactivities that concentrate in highly fluorescent round spots scattered along the newly grown neurites located close to the target cell. Almost every spot that is stained for serotonin is also positive for synapsin. In the presynaptic cell plated alone, the number of these varicosity‐like structures is substantially stable throughout the whole period; by contrast, when the presynaptic cell synapses the target, their number increases progressively parallel to the increase in the mean amplitude of cumulative excitatory postsynaptic potentials recorded at the same times. The data indicate that mollusc synapsin‐like peptides to some extent resemble their mammalian homologues, although they are not exclusively localized in nerve terminals and their expression strongly correlates with the formation of active synaptic contacts.
B-cell epitopes of African horse sickness virus serotype 4 recognised by immune horse sera

Identifying antigenic proteins and mapping their epitopes is important for the development of diagnostic reagents and recombinant vaccines. B-cell epitopes of African horse sickness virus (AHSV) have previously been mapped on VP2, VP5, VP7 and NS1, using mouse, rabbit and chicken monoclonal antibodies. A comprehensive study of the humoral immune response of five vaccinated horses to AHSV-4 antigenic peptides was undertaken. A fragmented-genome phage display library expressing a repertoire of AHSV-4 peptides spanning the entire genome was constructed. The library was affinity selected for binders on immobilised polyclonal immunoglobulin G (IgG) isolated from horse sera collected pre- and post-immunisation with an attenuated AHSV-4 monovalent vaccine. The DNA inserts of binding phages were sequenced with Illumina high-throughput sequencing. The data were normalised using pre-immune IgG-selected sequences. More sequences mapped to the genes coding for NS3, VP6 and VP5 than to the other genes. However, VP2 and VP5 each had more antigenic regions than each of the other proteins. This study identified a number of epitopes to which the horse’s humoral immune system responds during immunisation with AHSV-4.
Planning of Frequency Reuse and Relay Station's Location for Cellular Relaying Networks

This paper investigates an amplify and forward (AF) relaying scheme compatible with a legacy wireless system in cellular environments. In the proposed scheme, terminals and relay stations use different frequency bands for signal transmission. The two frequency bands for terminals and for relay stations are used by individual frequency reuse factors in cellular environments. We study frequency planning and a relay station's location for high spectral efficiency. The numerical results show that the spectral efficiency of a relaying scheme is enhanced by deploying a relay station close to the base station (BS) and using frequency reuse factor 1 for a relay station to BS link. I. INTRODUCTION Future wireless systems envisaged to support high data rate communications create transmit power problems since high data rate transmission requires large transmit power at a terminal of limited power capability. A relaying scheme, which can extend coverage area saving the transmit power, has been considered as an attractive solution (1)-(3) to this problem. When a relaying scheme is newly introduced into a legacy wireless system, a smooth migration from the legacy wireless system to an advanced wireless system with relaying has been envisaged. For smooth migration, it is essential to maintain compatibility between the legacy and advanced systems. For instance, in 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE)-advanced system with relay functions is expected to support LTE terminals which follow control procedure of LTE specifications ((4) etc.). It is also important for the advanced system to achieve high spectral efficiency. In this paper, we investigate an amplify and forward (AF) relaying scheme compatible with a legacy wireless system in an uplink of orthogonal frequency division multiple access (OFDMA) system. In the presented scheme, a relay station (RS) retransmits the received signal after changing a subband of the received signal. Thus, terminals and RSs use differ- ent frequency bands for signal transmission. The proposed relaying scheme can be applied to a legacy system by adding extra bandwidth for relaying. The proposed relaying scheme is compatible with legacy terminals, because it does not change any frame format of the legacy system. In the presented system, terminals can transmit signals without being aware of relaying transmission. We further study planning of frequency reuse factor (FRF) and appropriate location of a RS in cellular environments. In the presented scheme, frequency band for Fig. 1. A relay transmission model. terminals and that for RSs are used by individual frequency reuse factors. We analyze spectral efficiency under various FRFs and RS's locations to find a good FRF and RS's location. Although this paper assumes an OFDMA system on uplink, the proposed scheme can be straightforwardly applied to SC- FDMA scheme (4) by adding DFT processor at a terminal's transmitter part.
Capstones 12-1-2012 Shock Attenuation in Landing

Shock Attenuation in Landing by Bryon Christopher Applequist Dr. John Mercer, Examination Committee Chair Associate Professor of Kinesiology University of Nevada, Las Vegas Shock attenuation (SA) has been well studied in activities such as walking and running (Chu, et al. 2004; Derrick, et al. 2004; Mercer, et al. 2003); however, there is a lack of research regarding SA during landing. Furthermore, there is lack of information regarding which structures attenuate shock. The purpose of this study was to examine SA among the leg-hip, hip-head, and leg-head segments during landing. Each subject (n=10, Age 26.3 ± 2.71 years, Height 1.68 ± 0.08 m, Mass 70.49 ± 16.03 kg) was instrumented with accelerometers at the leg, hip and forehead. Subjects then performed landings from three heights: 30cm, 60cm, and 90cm. For each height, subjects completed 5 landing trials. Rest was provided between each trial. Order of conditions was randomized to account for fatigue and learning. During each landing, accelerations were recorded at 1000 Hz for the leg, hip, and head respectively using light-weight accelerometers. Data
ScienceDirect Information Technology and Quantitative Management , ITQM 2013 Sentiment Classification Based on AS-LDA Model

We address the task of sentiment classification identification of the polarity of the subjective document in this paper. We introduces a sentiment classification method called AS LDA. In this model, we assume that words in subjective documents consists of two parts: sentiment element words and auxiliary words which are sampled accordingly from sentiment topics and auxiliary topics. Sentiment element words include targets of the opinions, polarity words and modifiers of polarity words. Experimental results demonstrate that our approach outperforms Latent Dirichlet Allocation (LDA). c © 2014 The Authors. Published by Elsevier B.V.

Ground-based dual-frequency radiometry of bare soil at high temporal resolution

We report on an experiment linking microwave brightness temperatures and emissivities to the dynamics of in situ measured water content. The bare plot of 14/spl times/20 m was instrumented with two ground-based radiometers (1.4 and 11.4 GHz, respectively) and in situ time domain reflectometer (TDR) and temperature probes installed at five depths in three soil profiles. All data were recorded every 30 min from May to July 2002. The measured brightness temperature dynamics is a superposition of three patterns. The largest variations were caused by the changes in water content due to precipitation and the subsequent drying process. During dry periods, we observed daily oscillations of brightness temperature. Calculating effective soil temperatures based on the in situ measured temperature profiles revealed that these oscillations were partially due to changes in water content in the very topsoil. This effect was especially pronounced for the 11.4-GHz measurements, indicating that the very surface experienced the strongest changes in water content. At 1.4 GHz and horizontal polarization, the brightness temperature measurements turned out to be very sensitive to sun reflection at the ground. This reflection was visible through exceptionally high brightness temperature values at distinct times of the day. We observed pronounced hysteresis loops when comparing the emissivities of the two radiometers or the radiometric signals with the water content measured in situ at 2-cm depth. Such loops could be seen for the daily wetting and drying cycles as well as in the longer term drying and wetting behavior. This demonstrates that the gradient of the water content in the topsoil is a dynamic property depending on various time scales. These gradients affected the measurements of radiometers and TDR probes to different degrees and at different times. Despite an almost smooth surface, slight changes in the surface structure during the experiment caused a substantial variability with respect to the relationships between water content and emissivity for both radiometers. This is an indication that surface structures smaller than the wavelength may exert important effects on the emissivity of a bare soil.
On Inductive Abilities of Latent Factor Models for Relational Learning

Latent factor models are increasingly popular for modeling multi-relational knowledge graphs. By their vectorial nature, it is not only hard to interpret why this class of models works so well, but also to understand where they fail and how they might be improved. We conduct an experimental survey of state-of-the-art models, not towards a purely comparative end, but as a means to get insight about their inductive abilities. To assess the strengths and weaknesses of each model, we create simple tasks that exhibit first, atomic properties of binary relations, and then, common inter-relational inference through synthetic genealogies. Based on these experimental results, we propose new research directions to improve on existing models.
Tilted- and axial-beam formation by a single-arm rectangular spiral antenna with compact dielectric substrate and conducting plane

A single-arm rectangular spiral antenna is analyzed using the finite-difference time-domain method. The spiral is printed on a finite-size dielectric substrate backed by a finite-size conducting plane. Both the substrate and conducting planes are square with a side length L of less than 0.6/spl lambda//sub 0/ (/spl lambda//sub 0/: wavelength in free space). The radiation pattern is dependent on the outermost arm peripheral length C. The spiral whose peripheral length is within 2/spl lambda//sub g/<C<3/spl lambda//sub g/ (/spl lambda//sub g/: the guided wavelength of the current) radiates a tilted beam of circular polarization. When the peripheral length is decreased to /spl lambda//sub g/<C<2/spl lambda//sub g/, the spiral radiates an axial beam. The axial beam has a wide half-power beam width of approximately 102/spl deg/ (for L/spl ap/0.369/spl lambda//sub 0/) with a gain of approximately 6.7 dB. The axial beam shows a 15% frequency bandwidth for a 3 dB axial ratio criterion. Over this bandwidth, the voltage standing-wave ratio (VSWR) is less than two, as desired. The experimental results for the radiation pattern, gain, axial ratio, and VSWR are also presented.
Some observations on the morphology and developmental stages of Trypanosoma avium bakeri ssp.nov. from the red-whiskered bulbul (Otocompsa jocosa Linn.)

Trypanosoma avium bakeri ssp.nov. has been recorded from naturally infected red-whiskered bulbuls (Otocompsa jocosa Linn.). This trypanosome resembles T. avium Danilewsky, 1885 in general morphological features but it is larger in every respect. The parasite can also infect chicks, black-breasted quails and pigeons. The division stages of the parasite are also very interesting. Considering the different morphological criteria, division stages and loose host specificity, the parasite is designated as subspecies of T. avium. For the first time division stages of an avian trypanosome have been studied in detail in the peripheral circulation and bone marrow of the bird. The parasite multiplied by longitudinal binary fission and two types of plasmotomy. Our thanks are due to Dr S. Mookerjee, Professor and Head of the Department of Zoology, Presidency College, Calcutta for providing the necessary laboratory facilities and constant encouragement and for going through the manuscript and to Dr J. R. Baker, Department of Medical Protozoology, London School of Hygiene and Tropical Medicine, for his valuable suggestions in the preparation of this article.

SSVEP-Based Brain–Computer Interfaces Using FSK-Modulated Visual Stimuli

A brain-computer interface (BCI) based on steady-state visual-evoked potentials (SSVEP) has two difficulties: limitation of the number of commands and uneven probabilities of command execution. To address these problems, the present paper proposes a paradigm of BCI using frequency-modulated visual stimuli. The commands are translated into code words consisting of binary digits, to which visual stimuli with distinct frequencies are assigned. Frequencies of SSVEP are recognized to detect bits, and a command to be executed is determined from the sequence of detected bits. Experimental results show that the proposed paradigm achieves a reliable BCI with higher accuracies and balanced command executing probabilities.
On the Capacity Region of the Intensity-Modulation Direct-Detection Optical Broadcast Channel

The capacity of the intensity-modulation direct-detection free-space optical broadcast channel (OBC) is investigated. The Gaussian model with input-independent Gaussian noise is used, with both average and peak intensity constraints. An outer bound on the capacity region is derived by adapting Bergmans’ approach to the OBC. Inner bounds are derived by using superposition coding with either truncated-Gaussian distributions or discrete distributions. While the discrete input distribution achieves higher rates than the truncated-Gaussian distribution, the latter allows expressing the achievable rate region in a closed form. At high signal-to-noise ratio (SNR), it is shown that the truncated-Gaussian distribution is nearly optimal. It achieves the symmetriccapacity within a constant gap (independent of SNR), which approaches half a bit as the number of users grows large. It also achieves the capacity region within a constant gap, which depends on the number of users. At low SNR, it is shown that on-off keying with time-division multiple-access (TDMA) is optimal, as it achieves any point on the boundary of the developed outer bound. This is interesting in practice since both OOK and TDMA have low complexity. At moderate SNR (typically [0, 8] dB), a discrete distribution with a small alphabet size achieves a fairly good performance in terms of symmetric rate.
An Electrospray Ionization Mass Spectrometric Study of Iron Binding to Amyloid-β Peptides

Iron and other metal ions appear to play an important role in protein aggregation and are, therefore, likely to provide a link between protein aggregation and oxidative damage. This work reports on iron binding to the amyloid-β peptide (Aβ1–40), which affords a very specific electrospray ionization mass spectrometric (MS) spectrum. Both MS and tandem MS studies confirmed that the amyloid β-peptide displays a high affinity toward iron(III) ions, producing multi-charged molecular ions and peptide aggregates. Finally, the circular dichroism spectra indicate an unexpected modification of Aβ1–40 peptide conformation upon iron binding.
