Title A two-port antenna for wireless-powered UWB-RFID tags

This paper presents a two-port antenna including a receiving port and a transmitting one in the same volume. These two antennas are physically integrated and electrically isolated. The receiving antenna is a linearly polarized narrowband slot for energy harvesting, whereas the transmitting one is a circularly- polarized ultrawideband (UWB) quasi-spiral for signal radiation. The measurement results show that, the slot resonates at 5.8GHz, and the quasi-spiral has a 10-dB return loss bandwidth of 2.85{5.16GHz and a 3-dB axial-ratio bandwidth of 3.05{4.43GHz. The electrical isolation between these two antennas is more than 20 dB covering 1{8GHz. This two-port antenna is a good candidate for wireless powered UWB-RFID tags.
An efficient computer-aided design procedure for interpolating filter dimensions using least squares methods

This paper proposes a very efficient algorithm based on least squares (LSQ) methods to provide final dimensions of microwave filters. This algorithm just needs to start from very few accurate designs of practical filters, in order to provide the dimensions of any similar filter (same order and return loss values) with different center frequency f0 and bandwidth BW. Variations in f0 and BW have been studied to give models for the filter physical dimensions. Finally, both variables are included in a bivariate model allowing to directly obtain the filter dimensions for any combination of f0 and BW of the filter.
An Enhanced Graph-Based Infrastructure for Software Search Engines

The first generation of software search engines such as Merobase, Sourcerer etc. Showed that it is possible to support reasonably sophisticated searches over large bodies of software components using indices based on full-text search engines (most commonly Lucene). However, the "tricks" these engines use to map code structure to flat text are not only inflexible, they do not scale well to components composed of multiple program modules (e.g. Interfaces, classes etc.) As a result, beyond plain string matching, they are only able to support a limited and a priori fixed set of query types, and are rarely, if ever able, to find components composed of more than one code module. In this paper we present an index representation approach which is able to support the key information bound up in source code in a more accurate, flexible way, and thus efficiently support a much wider range of searches on components composed of multiple program modules.

Minimizing function-free recursive inference rules

Recursive inference rules arise in recursive definitions in logic programming systems and in database systems with recursive query languages. Let <italic>D</italic> be a recursive definition of a relation <italic>t</italic>. <italic>D</italic> is considered <italic>minimal</italic> if for any predicate <italic>p</italic> in a recursive rule in <italic>D</italic>, <italic>p</italic> must appear in a recursive rule in any definition of <italic>t</italic>. It is shown that testing for minimality is, in general, undecidable. However, an efficient algorithm for a useful class of recursive rules is presented, and it is used to transform a recursive definition to a minimal recursive definition. Evaluating the minimized definition avoids redundant computation without the overhead of caching intermediate results and run-time checking for duplicate goals.
Subunit Composition, Kinetic, and Permeation Properties of AMPA Receptors in Single Neocortical Nonpyramidal Cells

Native AMPA receptors (AMPARs) were investigated in neocortical fast-spiking (FS) and regular-spiking nonpyramidal (RSNP) cells. The onset of and recovery from desensitization as well as current rectification and single-channel conductance were studied by using fast glutamate application to outside-out patches. The GluR1–4 subunit, flip/flop splicing, and R/G editing expression patterns of functionally characterized cells were determined by single-cell reverse transcription-PCR to correlate the subunit composition of native AMPARs with their functional properties. Our sample, mostly constituted by RSNP neurons, predominantly expressed GluR3 flip and GluR2 flop. In individual cells, flip/flop splicing of each subunit appeared to be regulated independently, whereas for R/G editing all subunits were either almost fully edited or unedited. We confirmed that the relative GluR2 expression controls the permeation properties of native AMPARs, whereas none of the single molecular parameters considered appeared to be a key determinant of the kinetics. FS neurons displayed AMPARs with relatively homogeneous functional properties characterized by fast desensitization, slow recovery from desensitization, marked inward rectification, and large single-channel conductance. In contrast, these parameters varied over a wide range in RSNP neurons, and their combination resulted in various AMPAR functional patterns. Indeed, in different cells, fast or slow desensitization was found to be associated with either slow or fast recovery from desensitization. Similarly, fast or slow kinetics was associated with either strong or weak rectification. Our results suggest that kinetic and permeation properties of native AMPARs can be regulated independently in cortical neurons and probably do not have the same molecular determinants.
Multi-contact bilateral telemanipulation using wearable haptics

Bilateral telemanipulation refers to frameworks in which a human operator manipulates a master robotic interface and a slave robotic device emulates the behavior of the master, while haptic feedback is provided to the operator. For multi-contact bilateral teleoperation we intend master and slave systems that can establish multiple contact points with the user and with the environment. A paradigmatic example can be a multi-lingered robotic hand teleoperated by the human hand. Two of the most critical issues in this context are: (i) how to provide haptic feedback on multiple points of the human hand; (ii) how to solve the correspondence problem between the human hand and the robotic slave device. In this work, we propose finger-worn devices able to apply a three dimensional vector of force at a specific contact point to solve the multicontact feedback problem. For the correspondence problem, we propose an object-based mapping procedure. The approach is based on two virtual objects, defined both at the master and slave sides, to capture the human hand motion and to compute the related force feedback. The proposed approach has been tested in a telemanipulation framework where the master side was composed of a Leap Motion sensor used to track the hand plus three wearable haptic devices, while a robotic hand/arm system performed a manipulation task as slave.
An FPGA-Based Experiment Platform for Multi-Core System

The undergoing radical change of microprocessor architecture, from single-core design to multi-core design on a chip, has posed great challenge to computer system education. In this paper, we introduce an educational experiment platform for multi-core system design with commercial off-the-shelf FPGA chips and free open IP cores. From this simple platform, student can learn some common design patterns and techniques in multi-core system which can be a good start for real application design.
The flourishing of care in a multidisciplinary Faculty Learning Community

ABSTRACT In a multidisciplinary Faculty Learning Community focussed on exploring threshold concepts and bottlenecks in learning, care emerged as an unanticipated dimension to our work, transforming the ways we view teaching, learning, our disciplines, and educational development. In this piece, we reflect on the types of care that emerged and consider implications for educational development.
Persistent changes within the intrinsic kidney-associated NPY system and tubular function by litter size reduction.

BACKGROUND Intrauterine growth restriction (IUGR) is associated with an increased risk of renal diseases in adulthood. However, while low-birth-weight-infants often undergo accelerated postnatal growth, the impact of postnatal environmental factors such as nutrition and early postnatal stressors on renal development and function remains unclear. In this context, Neuropeptide Y (NPY) may act as a critical factor. NPY is a sympathetic coneurotransmitter involved in blood pressure regulation and tubular function. Yet, little is known about the expression and function of endogenous NPY in the kidney and the functional relevance for the transmission of persistent postnatal-induced effects. METHODS (1) IUGR was induced in Wistar rats by isocaloric protein restriction in pregnant dams. (2) Litter size was reduced to 6 (LSR6) or 10 (LSR10) male neonates. To differentiate the effect of postnatal nutrition and stressors, we additionally included home-cage-control animals without any postnatal manipulation. Animals were sacrificed at Day 70. RESULTS Litter size reduction (LSR) to 6 but not IUGR increased messenger RNA expression of endogenous NPY and down-regulated the NPY-receptors Y1 and Y2. Furthermore, dipeptidylpeptidase IV (DPPIV)--an enzyme that cleaves NPY--was decreased after LSR. Expression and the phosphorylation of mitogen-activated protein kinase 42/44 (intracellular signalling pathway of the receptor Y1) were altered. An impaired renal function with pronounced kaliuresis and natriuresis was observed at Day 70 after LSR. CONCLUSIONS Postnatal nutrition and stressors such as LSR lead to dysregulated signalling of NPY. These data demonstrate that factors in the early postnatal environment exert important changes in the tubular function, which may predispose to corresponding pathology.

In addition, modifiable walking pattern generation method is introduced and tested using the developed simulator. In the simulator, 3D design data of humanoid designed using CAD program are used. Example walking pattern is also demonstrated.
Form fostering: A novel design approach for interacting with parametric models in the embodied virtuality

This paper investigates the assimilation of embodied virtuality with parametric modelling to inform various stages of architectural design. Embodied virtuality is a term introduced by Mark Weiser in 1991 to describe the era of ubiquitous computing. Traditionally, the data used as input to a parametric model needs to co-exist in the digital world, stored in an archive or file system of our computer. However, with the proliferation of sensor and mobile devices, data can now be found everywhere in the physical world and the boundaries between the physical and the digital has become blurred. There is a need to integrate the real world and the digital information space for designing parametric models. The assimilation of digital data from the physical world with the existing CAD tools will create a synergy between form finding and form making. This paper introduces the notion of form fostering, which stands in between physical form making and digital form finding. Form fostering takes various inputs from the physical world to inform a parametric model or to actuate a physical model in the built environment. We present early experiments of Form Fostering, which include the use of a Wii Remote, an Arduino processing board, servo actuators and a camera as haptic input and interaction devices. The potential benefits of designing in embodied virtuality are significant since designers can get real-time input from both the physical context and from interaction with the parametric model.
Anion transport in heart.

Anion transport proteins in mammalian cells participate in a wide variety of cell and intracellular organelle functions, including regulation of electrical activity, pH, volume, and the transport of osmolites and metabolites, and may even play a role in the control of immunological responses, cell migration, cell proliferation, and differentiation. Although significant progress over the past decade has been achieved in understanding electrogenic and electroneutral anion transport proteins in sarcolemmal and intracellular membranes, information on the molecular nature and physiological significance of many of these proteins, especially in the heart, is incomplete. Functional and molecular studies presently suggest that four primary types of sarcolemmal anion channels are expressed in cardiac cells: channels regulated by protein kinase A (PKA), protein kinase C, and purinergic receptors (I(Cl.PKA)); channels regulated by changes in cell volume (I(Cl.vol)); channels activated by intracellular Ca(2+) (I(Cl.Ca)); and inwardly rectifying anion channels (I(Cl.ir)). In most animal species, I(Cl.PKA) is due to expression of a cardiac isoform of the epithelial cystic fibrosis transmembrane conductance regulator Cl(-) channel. New molecular candidates responsible for I(Cl.vol), I(Cl.Ca), and I(Cl.ir) (ClC-3, CLCA1, and ClC-2, respectively) have recently been identified and are presently being evaluated. Two isoforms of the band 3 anion exchange protein, originally characterized in erythrocytes, are responsible for Cl(-)/HCO(3)(-) exchange, and at least two members of a large vertebrate family of electroneutral cotransporters (ENCC1 and ENCC3) are responsible for Na(+)-dependent Cl(-) cotransport in heart. A 223-amino acid protein in the outer mitochondrial membrane of most eukaryotic cells comprises a voltage-dependent anion channel. The molecular entities responsible for other types of electroneutral anion exchange or Cl(-) conductances in intracellular membranes of the sarcoplasmic reticulum or nucleus are unknown. Evidence of cardiac expression of up to five additional members of the ClC gene family suggest a rich new variety of molecular candidates that may underlie existing or novel Cl(-) channel subtypes in sarcolemmal and intracellular membranes. The application of modern molecular biological and genetic approaches to the study of anion transport proteins during the next decade holds exciting promise for eventually revealing the actual physiological, pathophysiological, and clinical significance of these unique transport processes in cardiac and other mammalian cells.
Retrieval of Images Based on Texture and Color Features

Content-based image retrieval (CBIR) is a new but widely espoused method for finding images from enormous image databases. The need of content based image retrieval technique is in different domains such as medical imaging, crime prevention, weather forecasting, surveillance, historical research and remote sensing. This paper presents the content based image retrieval, using texture and color features. The different features are extracted and the effectiveness of content based image retrieval can be increased. The proposed system has confirmed a faster retrieval method on a COREL image data base and CASIA image database containing 1000 color images and medical images respectively. The performance of this proposed method is evaluated using color image and medical image database and measured using average precision, average recall. The experimental result shows this proposed method has accomplished the highest retrieval rate.
Highly sensitive myosin phosphorylation analysis in the renal afferent arteriole

The regulation of smooth muscle contraction and relaxation involves phosphorylation and dephosphorylation of regulatory proteins, particularly myosin. To elucidate the regulatory mechanisms, analyzing the phosphorylation signal transduction is crucial. Although a pharmacological approach with selective inhibitors is sensitive and a useful technique, it leads to speculation regarding a signaling pathway but does not provide direct evidence of changes at a molecular level. We developed a highly sensitive biochemical technique to analyze phosphorylation by adapting Phos-tag SDS-PAGE. With this technique, we successfully analyzed myosin light chain (LC20) phosphorylation in tiny renal afferent arterioles. In the rat afferent arterioles, endothelin-1 (ET-1) induced diphosphorylation of LC20 at Ser19 and Thr18 as well as monophosphorylation at Ser19 via ETB receptor activation. Considering that LC20 diphosphorylation can decrease the rate of dephosphorylation and thus relaxation, we concluded that LC20 diphosphorylation contributes, at least in part, to the prolonged contraction induced by ET-1 in the renal afferent arteriole.
From Co-Ops to Community Land Trusts: Tracing the Historical Evolution and Policy Mobilities of Collaborative Housing Movements

ABSTRACT This article explores the historical development of two different collaborative housing models: Liverpool’s housing co-operative movement of the 1970s, when public tenants successfully struggled for collective dweller control in designing, developing and managing their own housing; and, today, Liverpool’s nascent urban community land trust (CLT) movement. The genesis and institutionalization of each is analysed through mobile urbanism, policy mobilities and planning histories perspectives. Both Liverpool’s co-ops and CLTs are shown to have been mobilized through ideas adapted from elsewhere, mutating upon exposure to contextual factors embedded in place. Contemporary CLT campaigns can be traced back to various sources: CLT experiments by professional or arms-length state agencies; and previous periods of collaborative housing activism, notably the 1970s co-ops. The article situates these movements within a collaborative housing conceptual framework and draws out the implications of these genealogical findings for the further development of collaborative housing.
Determining effective colour components for skin detection using a clustered neural network

Object detection problems-skin detection here can be considered as object recognition problems with two classes. In this paper, each given class is clustered using the Kmeans algorithm into multiple subclasses and a Multilayer perceptron (MLP) neural network (NN) is trained for each clusters separately. In the testing phase, each point is compared with centers of clusters and the network related to closest center is selected for each new cluster. Besides the system performance improvement, it also can significantly reduce the testing time. Then the Utans algorithm as a trained NNs-based feature selection method is applied to 44 color components of 15 different color spaces. The obtained results show that the presented algorithm compare to other algorithms has higher performance and less execution time as well.
TASS 2014 - The Challenge of Aspect-based Sentiment Analysis

Currently, reputation and sentiment analysis are trendy tasks. However, the interest on these two tasks is growing by the need of knowing the polarity of the opinions published on the Internet. TASS is a workshop whose goal is to boost the research on sentiment analysis in Spanish. Hereinafter the third issue of TASS is described, in which four tasks have been proposed. Two of the proposed tasks are known by former participants and the other two ones are new. These new tasks are related to sentiment analysis at entity level, and they are circumscribed on the Social TV phenomenon.
Me, my selfie, and I: The relations between selfie behaviors, body image, self-objectification, and self-esteem in young women.

Due to the enormous popularity of social networking sites (SNSs), online and offline social lives seem inextricably linked, which raises concerns for how SNS use relates to psychological health. Similarly, the omnipresence of selfies on SNSs—a form of appearance-related exposure—raises concerns regarding psychological health. This study aimed to investigate the relationships between body image, self-objectification, self-esteem, and various selfie behaviors among young women (N = 179). We hypothesized that a worsened body image (i.e., higher body dissatisfaction or lower body appreciation), higher levels of self-objectification, and lower self-esteem would precede greater engagement in selfie behaviors. Structural equation modeling showed that body appreciation is associated with greater engagement in selfie selection and deliberate posting, and that self-objectification is related to greater engagement in all selfie behaviors assessed. In support of our proposed model, a reversed model was also tested that showed poorer results. These findings suggest that body image may serve not only as an outcome of SNS use but also as a motive preceding selfie behaviors.
Interdependence of chronic hydraulic dysfunction and canopy processes can improve integrated models of tree response to drought

Hydraulic systems of plants have evolved in the context of carbon allocation and fitness trade‐offs of maximizing carbon gain and water transport in the face of short and long‐term fluctuations in environmental conditions. The resulting diversity of traits include a continuum of isohydry‐anisohydry or high to low relative stomatal closure during drought, shedding of canopy foliage or disconnecting roots from soil to survive drought, and adjusting root areas to efficiently manage canopy water costs associated with photosynthesis. These traits are examined within TREES, an integrated model that explicitly couples photosynthesis and carbon allocation to soil‐plant hydraulics and canopy processes. Key advances of the model are its ability to account for differences in soil and xylem cavitation, transience of hydraulic impairment associated with delayed or no refilling of xylem, and carbon allocation to plant structures based on photosynthetic uptake of carbon and hydraulic limitations to water transport. The model was used to examine hydraulic traits of cooccurring isohydric (piñon pine) and anisohydric (one‐seed juniper) trees from a field‐based experimental drought. Model predictions of both transpiration and leaf water potential were improved when there was no refilling of xylem over simulations where xylem was able refill in response to soil water recharge. Model experiments with alternative root‐to‐leaf area ratios (RR/L) showed the RR/L that supports maximum cumulative water use is not beneficial for supporting maximum carbon gain during extended drought, illustrating how a process model reveals trade‐offs in plant traits.
