VISUO-SPATIAL MENTAL PROCESSES AS REVEALED BY SPONTANEOUS EYE MOVEMENTS

Figure 2. Examples of eye movements in individual trials. The gaze is initially in the centre position. The two lines encompass the angular sector supposed to be spanned mentally clockwise. In the mental rotation task, the eye movements typology included single-saccades, as well as sequences of up to seven eight saccades describing an almost circular trajectory. In o nefourth of the trials there were more than three saccades. In the motion imagery task, the eye movement pattern was more regular, consisting mostly of a sequence of small, regularly spaced saccades.

Position based visual servoing: keeping the object in the field of vision

Visual servoing requires an object in the field of view of the camera, in order to control the robot evolution. Otherwise, the virtual link is broken and the control loop cannot continue to be closed. In this paper, a novel approach is presented in order to guarantee that the object remains in the field of view of the camera during the whole robot motion. It consists in tracking an iteratively computed trajectory. A position based modeling adapted to a moving target object is established, and is used to control the trajectory. A nonlinear decoupling approach is then used to control the robot. Experiments, demonstrating the capabilities of this approach, have been conducted on a Cartesian robot connected to a real time vision system, with a CCD camera mounted on the end effector of the robot.

An efficient pilot pattern design for channel estimation in OFDM systems

In this paper, channel estimation methods based on pilot patterns are investigated. LS and MMSE techniques are used for estimating channel at pilot subcarriers in block type and comb type methods. Channel estimation at data subcarriers is done using interpolation methods like linear interpolation, spline interpolation, low-pass interpolation, time domain interpolation. Window based channel estimation using Hann window is also studied. A new pilot pattern is proposed for channel estimation at pilot based on comb-type. The performances of all schemes are compared with QPSK as modulation technique with Rayleigh fading channel in presence of additive white Gaussian noise. Simulations show that proposed pattern shows better improvement in terms of BER comparisons and MSE plots.
Entity matching for semistructured data in the Cloud

The rapid expansion of available information, on the Web or inside companies, is increasing. With Cloud infrastructure maturing (including tools for parallel data processing, text analytics, clustering, etc.), there is more interest in integrating data to produce higher-value content. New challenges, notably include entity matching over large volumes of heterogeneous data. In this paper, we describe an approach for entity matching over large amounts of semistructured data in the Cloud. The approach combines ChuQL[4], a recently proposed extension of XQuery with MapReduce, and a blocking technique for entity matching which can be efficiently executed on top of MapReduce. We illustrate the proposed approach by applying it to extract automatically and enrich references in Wikipedia and report on an experimental evaluation of the approach.
Valuing Managerial Flexibility: An Application of Real-Option Theory to Mining Investments

Abstract The value of managerial flexibility is assessed using data on prices, costs, grades, reserves, ore extraction, and metal output for a panel of Canadian copper mines. A real-option model is estimated and solved for project and option values. Most empirical researchers (i) consider the initial-investment decision but neglect flexible operation thereafter, (ii) assume that price is stochastic but ignore cost and reserve uncertainty, and (iii) model price as a nonstationary stochastic process. The evolution of three state variables, price, cost, and reserves, is assessed here. Differences in assumptions compared to others are found to lead to large differences in estimated project and option values.
Some Algorithmic Results on Restrained Domination in Graphs

A set $D\subseteq V$ of a graph $G=(V,E)$ is called a restrained dominating set of $G$ if every vertex not in $D$ is adjacent to a vertex in $D$ and to a vertex in $V \setminus D$. The \textsc{Minimum Restrained Domination} problem is to find a restrained dominating set of minimum cardinality. Given a graph $G$, and a positive integer $k$, the \textsc{Restrained Domination Decision} problem is to decide whether $G$ has a restrained dominating set of cardinality a most $k$. The \textsc{Restrained Domination Decision} problem is known to be NP-complete for chordal graphs. In this paper, we strengthen this NP-completeness result by showing that the \textsc{Restrained Domination Decision} problem remains NP-complete for doubly chordal graphs, a subclass of chordal graphs. We also propose a polynomial time algorithm to solve the \textsc{Minimum Restrained Domination} problem in block graphs, a subclass of doubly chordal graphs. The \textsc{Restrained Domination Decision} problem is also known to be NP-complete for split graphs. We propose a polynomial time algorithm to compute a minimum restrained dominating set of threshold graphs, a subclass of split graphs. In addition, we also propose polynomial time algorithms to solve the \textsc{Minimum Restrained Domination} problem in cographs and chain graphs. Finally, we give a new improved upper bound on the restrained domination number, cardinality of a minimum restrained dominating set in terms of number of vertices and minimum degree of graph. We also give a randomized algorithm to find a restrained dominating set whose cardinality satisfy our upper bound with a positive probability.
I/Q Imbalance Aware Widely-Linear Receiver for Uplink Multi-Cell Massive MIMO Systems: Design and Sum Rate Analysis

In-phase/quadrature-phase imbalance (IQI) is one of the most important hardware impairments in communication systems. It arises in the analogue parts of direct conversion transceivers and can cause severe performance losses. In this paper, IQI aware widely-linear (WL) channel estimation and data detection schemes for uplink multicell massive multiple-input multiple-output (MIMO) systems are proposed. The resulting receiver is a WL extension of the minimum mean-square-error (MMSE) receiver and jointly mitigates multiuser interference and IQI by processing the real and the imaginary parts of the received signal separately. Thereby, the IQI arising at both the base station and the user terminals is taken into account. The considered channel state information acquisition model includes the effect of pilot contamination, which is caused by the reuse of the same training sequences in neighbouring cells. We apply results from random matrix theory to derive analytical expressions for the asymptotic achievable sum rates of the proposed IQI aware and conventional IQI unaware (IQU) receivers in the large system limit. Our simulation and analytical results show that the performance of the proposed IQI aware WLMMSE (IQA-WLMMSE) receiver in a system with IQI is close to that of the MMSE receiver in an ideal system without IQI.
On the representation of band-limited signals using finitely many bits

In this paper, we consider the question of representing an entire function of finite order and type in terms of finitely many bits, and reconstructing the function from these. Instead of making any further assumptions about the function, we measure the error in reconstruction in a suitably weighted Lp norm. The optimal number of bits in order to obtain a given accuracy is given by the Kolmogorov entropy. We determine this entropy in the case of certain compact subsets of these weighted Lp spaces, and obtain constructive algorithms to determine the asymptotically optimal bit representation from finitely many samples of the function. Our theory includes both equidistant and non-uniform sampling. The reconstructions are polynomials, having several other optimality properties.
The extraordinarily bright optical afterglow of GRB 991208 and its host galaxy

Broad-band optical observations of the extraordi- narily bright optical afterglow of the intense gamma-ray burst GRB 991208 started � 2.1 days after the event and continued until 4 Apr 2000. The flux decay constant of the optical after- glow in the R-band is 2.30 ± 0.07 up to � 5 days, which
Human T-lymphotropic virus type I infection and idiopathic thrombocytopnic purpura

Abstract Human T-lymphotropic virus type I (HTLV-I) is the causative agent in adult T-cell leukemia and HTLV-I associated myelopathy. Some other diseases such as uveitis, chronic thyroiditis, Sjögren syndrome, arthritis, acute myeloid leukemia and myelodysplastic syndrome may be also associated with HTLV-I. Several case reports have suggested the possible combination of idiopathic thrombocytopenic purpura (ITP) and HTLV-I infection. In these studies and from our current report, we found 17 patients (22.1%) with HTLV-I infection among 77 ITP patients. The prevalence of HTLV-I infection among ITP patients was higher than that of healthy volunteers (5? ~? 10%). The ITP patients with HTLV-I infection were older than the patients without HTLV-I infection, and the ITP patients with HTLV-I infection had poor response to prednisolone therapy. Among 17 ITP patients with HTLV-I infection, 9 patients received prednisolone therapy. Although most patients had transient increase of platelet counts, only two of them had partial responses (PR) at the last observation date. Five patients underwent splenectomy, and four of them had complete responses (CR) and the remaining patient had a (PR). Four patients received eradication of Helicobactor pylori ( H. pylori ) infection, and all patients had CRs. Therefore, the ITP patients with HTLV-I infection should receive eradication therapy in the case of H. pylori infection as the first step of therapy and the splenectomy should be considered, if there is no response to conventional therapy. Human immunodeficiency virus (HIV) causes thrombocytopenia in 10% of patients with active HIV disease. The etiologies of HIV thrombocytopenia are considered as follows, the escalated destruction of platelets by the immune system, damage to megakaryocytes by HIV infection and the inhibition of thrombopoiesis by some anti-viral drugs. In the case of ITP patients with HTLV-I infection, the main etiology may be the increased destruction of platelets by immune system. The proviral load and the integration pattern of HTLV-I should be examined to clarify the stage of HTLV-I infection. The possibility of infection of the megakaryocytes by HTLV-I should be also examined for etiological approach.
Frontiers in Synaptic Neuroscience Synaptic Neuroscience

lates of learning and memory in the mammalian brain has focused on neurons that are specifically active during learning. Eyeblink conditioning in the cat or the rabbit is well documented in this respect since neurons from active circuits during the conditioning exhibit in vitro an excitability that is significantly elevated In several cases, the after-hyperpolarization (AHP) current was found to be depressed. Other forms of learning such as spatial or olfactory learning involve the regulation of neuronal excitability (Saar et al., 1998; Oh et al., 2003). These observations therefore suggest that the memory trace could not only be supported by selective changes in synaptic strength but that modifications in neuronal excitability might also contribute to the cellular substrate of the memory trace in the brain. This conclusion must be however qualified since in hippocampal and cortical neurons, increased neuronal excitability is no longer detectable 8 days after eyeblink conditioning, although learning is still established (Moyer et al., 1996). These in vivo studies, therefore suggest that synaptic or propagated activity during the induction phase may determine the induction of intrinsic plasticity. However, several key questions regarding the induction and expression mechanisms of intrinsic plasticity cannot be satisfactorily addressed at a cellular and molecular scale in the in vivo preparation and the use of in vitro assays must be envisaged to accurately control synaptic activity, membrane potential as well as pharmacologically isolated membrane currents. In central cortical neurons, excitatory postsynaptic potentials (EPSPs) measured at the axon hillock result from a tight interplay between synaptic and intrinsic voltage-gated conductances that either amplify or attenuate excitatory synaptic potentials (review in Spruston, 2008). Any modifications in this fragile equilibrium may in turn facilitate or diminish the probability that a given
An Axiomatic Approach for Persuasion Dialogs

Several systems were developed for supporting public persuasion dialogs where two agents with conflicting opinions try to convince an audience. For computing the outcomes of dialogs, these systems use (abstract or structured) argumentation systems that were initially developed for nonmonotonic reasoning. Despite the increasing number of such systems, there are almost no work on high level properties they should satisfy. This paper is a first attempt for defining postulates that guide the well-definition of dialog systems and that allow their comparison. We propose six basic postulates (including e.g. the finiteness of generated dialogs). We then show that this set of postulates is incompatible with those proposed for argumentation systems devoted for nonmonotonic reasoning. This incompatibility confirms the differences between persuading and reasoning. It also suggests that reasoning systems are not suitable for computing the outcomes of dialogs.
Patient cloth with motion recognition sensors based on flexible piezoelectric materials

In this paper, we introduce a patient cloth for position monitoring using motion recognition sensors based on flexible piezoelectric materials. The motion recognition sensors are embedded in three parts, which are the knee, hip and back, in the patient cloth. We use polyvinylidene fluoride (PVDF) as the flexible piezoelectric material for the sensors. By using the piezoelectric effect of the PVDF, we detect electrical signals when the cloth is bent or extended. We analyze the sensing values for our human motions by processing the sensor outputs in a custom-made program. Specifically, we focus on the transitions between standing and sitting, and sitting knee extension and supine position, which are important motions for patient monitoring.
LEVERAGING THE POWER OF BIG DATA FOR ROBUST PROCESS OPERATIONS UNDER UNCERTAINTY

We propose a data-driven outlier-insensitive adaptive robust optimization framework that leverages big data in industries. A Bayesian nonparametric model – the Dirichlet process mixture model – is adopted to extract the information embedded within uncertainty data via a variational inference algorithm. We then devise data-driven uncertainty sets for adaptive robust optimization. This Bayesian nonparametric model is seamlessly integrated with adaptive optimization approach through a novel four-level robust optimization framework. This framework explicitly considers the correlation, asymmetry and multimode of uncertainty data, and as a result generates less conservative solutions. Additionally, this framework is robust not only to parameter variations, but also to data outliers. An efficient tailored column-andconstraint generation algorithm is proposed for the resulting problem that cannot be solved directly by any off-the-shelf optimization solvers. The effectiveness and advantages of the modeling framework and solution algorithm are demonstrated through industrial applications.
INFLUENCE OF REACTION MEDIUM ON CO 2 PHOTOCATALYTIC REDUCTION YIELDS OVER ZnS-MMT

The reduction of CO2 by photocatalysts is one of the most promising methods since CO2 can be reduced to useful compounds by irradiating it with UV light at room temperature and ambient pressure. The aim of this work was to assess the effect of a reaction media on CO2 photocatalytic reduction yields over ZnS nanoparticles deposited on montmorillonite (ZnS-MMT). Four different reaction media, such as NaOH, NaOH+Na2SO3 (1:1), NH4OH, NH4OH+Na2SO3 (1:1), were tested. The pure sodium hydroxide was better than ammonium hydroxide for the yields of the both gas phase (CH4 and CO) and liquid phase (CH3OH). The addition of Na2SO3 improved methanol yields due to the oxidation prevention of incipient methanol to carbon dioxide. The gas phase yields were decreased by the Na2SO3 addition. The best tested reaction medium for the photocatalytic reduction of CO2 was the solution of sodium hydroxide. Abstrakt Redukce CO2 pomocí fotokatalyzátorů je jedna z nejslibnějších metod, jelikož CO2 může být redukován na užitečné sloučeniny ozařováním UV zářením při pokojové teplotě a tlaku.

CpG‐oligodeoxynucleotides induce mobilization of hematopoietic progenitor cells into peripheral blood in association with mouse KC (IL‐8) production

The immune system of vertebrates detects bacterial DNA as a “danger signal” based on the presence of unmethylated CpG motifs. We examined whether oligodeoxynucleotides (ODNs) with CpG motifs (CpG‐ODNs) also induce mobilization of hematopoietic progenitor cells (HPCs). Mice challenged with CpG‐ODNs showed an increase in peripheral blood colony‐forming units (CFU) with a peak at day 4 after treatment, associated with an increase, starting 30 min after CpG treatment, in serum levels of mouse keratinocyte‐derived chemokine (mKC), a functional homolog of human interleukin (IL) 8; production of granulocyte‐colony‐stimulating factor (CSF) was also detected. Mobilization and mKC induction were sequence‐specific and dose‐dependent occurring even with low doses of CpG‐ODNs. Interestingly, intestinal cells were involved in mKC production. HPC mobilization by CpG‐ODNs was dependent on peripheral blood mononuclear cells since mobilization was reduced in neutrophil‐depleted mice. Moreover, CpG‐ODN treatment significantly increased G‐CSF mobilizing capacity. Finally, pretreatment with an anti‐mKC neutralizing antibody significantly reduced CpG‐induced mobilization, further supporting a role for mKC. Thus, bacterial DNA is a “danger signal” not only for immune cells but also for hematopoietic cells, communicating the need for increased hematopoiesis during infections and for the renewal of the immune system. The HPC mobilization activity of CpG‐ODNs will need to be considered in the design of treatment regimens for cancer clinical trials using CpG‐ODNs in association with chemotherapy. © 2005 Wiley‐Liss, Inc.
A Mutation in Arabidopsis SEEDLING PLASTID DEVELOPMENT1 Affects Plastid Differentiation in Embryo-Derived Tissues during Seedling Growth1[W][OA]

Oilseed plants like Arabidopsis (Arabidopsis thaliana) develop green photosynthetically active embryos. Upon seed maturation, the embryonic chloroplasts degenerate into a highly reduced plastid type called the eoplast. Upon germination, eoplasts redifferentiate into chloroplasts and other plastid types. Here, we describe seedling plastid development1 (spd1), an Arabidopsis seedling albino mutant capable of producing normal green vegetative tissues. Mutant seedlings also display defects in etioplast and amyloplast development. Precocious germination of spd1 embryos showed that the albino seedling phenotype of spd1 was dependent on the passage of developing embryos through the degreening and dehydration stages of seed maturation, suggesting that SPD1 is critical during eoplast development or early stages of eoplast redifferentiation. The SPD1 gene was found to encode a protein containing a putative chloroplast-targeting sequence in its amino terminus and also domains common to P-loop ATPases. Chloroplast localization of the SPD1 protein was confirmed by targeting assays in vivo and in vitro. Although the exact function of SPD1 remains to be defined, our findings reveal aspects of plastid development unique to embryo-derived cells.
The emergency observation and assessment ward

A recent development to reduce ED crowding and increase urgent patient admissions is the opening of an Emergency Observation and Assessment Ward (EOA Ward). At these wards urgent patients are temporarily hospitalized until they can be transferred to an inpatient bed. In this paper we present an overflow model to evaluate the effect of employing an EOA Ward on elective and urgent patient admissions.
