MIMO antenna configuration for Femtocell application

Recent advances in the development of mobile applications have led to a need for mobile broadband platforms which support the capacity that these applications require. An investigation of possible antenna configurations that would be compatible with MIMO systems suitable for Femtocell applications is presented. A MIMO configuration of up to 6×2 antenna elements is modelled with the use of HFSS. Its performance is measured by means of the ideal-channel capacity increase it provides compared to a SISO architecture. The performance of the same MIMO configuration is then successfully modelled in Epsilon™ (Roke's own channel modelling tool) with the use of a non-ideal indoor model. The simulations show that with the proposed configuration, it is possible to achieve a two-fold capacity increase compared to a SISO architecture in both channel conditions.
Di erential Geometry of Autoregressive Fractionally Integrated Moving Average Models

The di erential geometry of autoregressive fractionally integrated moving average processes is developed. Properties of Toeplitz forms associated with the spectral density functions of these long memory processes are used to compute the geometric quantities. The role of these geometric quantities on the asymptotic bias of the maximum likelihood estimates of the model parameters and on the Bartlett corrections to the likelihood ratio test statistics for the fractional di erence parameter is discussed.
Climate discourse: eluding literacy, justice & inclusion, by evading causation, privilege & diversity

ABSTRACT This paper examines climate change discourse in Southeast Florida through the lenses of intersectionality and environmental and climate justice. Specifically, we highlight two less pronounced justice principles, education and socioecological interdependency, in combination with a relational approach to intersectionality, to study how climate change is presented in a particular time (pre-2015) and place (Southeast Florida). We analyze media, event, visual, and resident-researcher data and find three paired narratives and omissions put forth primarily by middle-aged, middle-class professionals. First, we identify a rise of climate educators who promote climate reality and impacts, while neglecting the anthropogenic causes of climate change. Second, geophysical lessons are advanced, amid confounding coastal development. Third, professional interests are voiced, while population diversity, including migration histories and generational futures, go unrecognized as potential resources or concerns to broaden climate interest and action within and beyond the region. At a time when the region was discovering the early impacts of climate change, we find both progress and avoidance toward raising awareness and supporting action, whether intentionally, unintentionally, or consequentially.
Intravenously Injected Human Apolipoprotein A‐I Rapidly Enters the Central Nervous System via the Choroid Plexus

Background Brain lipoprotein metabolism is dependent on lipoprotein particles that resemble plasma high‐density lipoproteins but that contain apolipoprotein (apo) E rather than apoA‐I as their primary protein component. Astrocytes and microglia secrete apoE but not apoA‐I; however, apoA‐I is detectable in both cerebrospinal fluid and brain tissue lysates. The route by which plasma apoA‐I enters the central nervous system is unknown. Methods and Results Steady‐state levels of murine apoA‐I in cerebrospinal fluid and interstitial fluid are 0.664 and 0.120 μg/mL, respectively, whereas brain tissue apoA‐I is ≈10% to 15% of its levels in liver. Recombinant, fluorescently tagged human apoA‐I injected intravenously into mice localizes to the choroid plexus within 30 minutes and accumulates in a saturable, dose‐dependent manner in the brain. Recombinant, fluorescently tagged human apoA‐I accumulates in the brain for 2 hours, after which it is eliminated with a half‐life of 10.3 hours. In vitro, human apoA‐I is specifically bound, internalized, and transported across confluent monolayers of primary human choroid plexus epithelial cells and brain microvascular endothelial cells. Conclusions Following intravenous injection, recombinant human apoA‐I rapidly localizes predominantly to the choroid plexus. Because apoA‐I mRNA is undetectable in murine brain, our results suggest that plasma apoA‐I, which is secreted from the liver and intestine, gains access to the central nervous system primarily by crossing the blood–cerebrospinal fluid barrier via specific cellular mediated transport, although transport across the blood–brain barrier may also contribute to a lesser extent.
Does Science Make a Difference? Investment, Finance and Corporate Governance in German Industries

This paper examines the impact of industry knowledge conditions and corporate governance structures on tangible investment and its financing. Based on a large panel data set of German firms we investigate whether liquidity constraints vary systematically across firms engaged in activities reflecting very different knowledge conditions. In particular, we compare the extent of liquidity constraints in science-based firms with non science-based firms. This distinction is important because science-based firms generally fit the characteristics of market failure identified by Kenneth Arrow. Science-based economic activity is subject to high uncertainty, asymmetric knowledge and non-exclusiveness so liquidity constraints might be severe. Surprisingly, science seems to make a difference in that firms in science-based industries are less liquidity constrained than are their non science-based counterparts. In fact, the larger science-based firms do not seem to face liquidity constraints at all. However, governance structures play an important role. After accounting for the mode of corporate governance, we observe that the owner-controlled but not the manager-controlled firms are significantly liquidity constrained.
Impact analysis and post-impact motion control issues of a free-floating Space robot subject to a force impulse

This article presents impact dynamic analysis of a free-floating space robot, subject to a force impulse at the hand. We study the joint and the base reactions in terms of finite velocity changes and clarify their role for the post-impact motion behavior of the robot. The analysis makes use of a joint-space orthogonal decomposition procedure involving the so called reaction null space. The article focuses on the specific case of a nonredundant arm and a reaction null space in terms of base angular motion. We further show that with proper post-impact control it is possible to transfer the whole angular momentum from the base toward the manipulator, and in the same time to reduce the joint velocity.
Discontinuous Galerkin Method for Total Variation Minimization on Inpainting Problem

This paper is concerned with the numerical minimization of energy functionals in BV (Ω) (the space of bounded variation functions) involving total variation for gray-scale 1-dimensional inpainting problem. Applications are shown by finite element method and discontinuous Galerkin method for total variation minimization. We include the numerical examples which show the different recovery image by these two methods. Keywords—finite element method, discontinuous Galerkin method, total variation minimization, inpainting
Characteristics of Human Turbinate-Derived Mesenchymal Stem Cells Are Not Affected by Allergic Condition of Donor

The characteristics of mesenchymal stem cells (MSCs) derived from human turbinates (hTMSCs) have not been investigated in allergic rhinitis. We evaluated the influence of allergic state of the donor on the characteristics, proliferation, and differentiation potential of hTMSCs, compared with hTMSCs derived from non-allergic patients. hTMSCs were isolated from five non-allergic and five allergic patients. The expression of toll-like receptors (TLRs) in hTMSCs was measured by FACS, and cell proliferation was measured using a cell counting kit. Cytokine secretion was analyzed using multiplex immunoassays. The osteogenic, chondrogenic, and adipogenic differentiation potentials of hTMSCs were evaluated by histology and gene expression analysis. In allergic patients, FACS analysis showed that TLR3 and TLR4 were more highly expressed on the surface of hTMSCs than TLR2 and TLR5. The proliferation of hTMSCs was not influenced by the presence of TLR priming. The expression of IL-6, IL-8, IL-12, IP-10, and RANTES was upregulated after the TLR4 priming. The differentiation potential of hTMSCs was not influenced by TLR priming. These characteristics of hTMSCs were similar to those of hTMSCs from non-allergic patients. We conclude that the allergic condition of the donor does not influence TLR expression, proliferation, or immunomodulatory potential of hTMSCs.
Stability of Allelic Frequencies and Distributions of Candida albicans Microsatellite Loci from U.S. Population-Based Surveillance Isolates

ABSTRACT Allelic distributions and frequencies of five Candida albicans microsatellite loci have been determined for strains isolated from the bloodstream and obtained through active population-based surveillance in two U.S. metropolitan areas between 1998 and 2000. These data were compared to data for isolates obtained from two other U.S. regions in 1992 to 1993. In a majority of pairwise combinations between sites, no evidence was seen for shifts in microsatellite allelic frequencies. One to three alleles were highly predominant and correlated with major genotypes. These data both support the concepts of allelic stability and genetic equilibria and suggest that, in the United States, strains of C. albicans isolated from the bloodstream may form a defined, genetically homogeneous population across geographical distance and time.
Step-size control for width adaptation in radial basis function networks for nonlinear channel equalization

A method of width adaptation in the radial basis function network (RBFN) using stochastic gradient (SG) algorithm is introduced. Using Taylor's expansion of error signal and differentiating the error with respect to the step-size, the optimal time-varying step-size of the width in RBFN is derived. The proposed approach to adjusting widths in RBFN achieves superior learning speed and the steady-state mean square error (MSE) performance in nonlinear channel environment. The proposed method has shown enhanced steady-state MSE performance by more than 3 dB in both nonlinear channel environments. The results confirm that controlling over step-size of the width in RBFN by the proposed algorithm can be an effective approach to enhancement of convergence speed and the steady-state value of MSE.
Release kinetics of copeptin in patients undergoing transcoronary ablation of septal hypertrophy.

BACKGROUND The release kinetics of copeptin in patients with acute myocardial infarction (AMI) have been difficult to establish. METHODS We analyzed the release kinetics of copeptin in patients with hypertrophic obstructive cardiomyopathy undergoing transcoronary ablation of septal hypertrophy (TASH) as a model of AMI. We included 21 consecutive patients who underwent TASH. Blood samples were collected before and at 15, 30, 45, 60, 75, 90, and 105 min, and at 2, 4, 8, and 24 h after TASH. Serum copeptin was quantified by a sandwich immunoluminometric assay. RESULTS All patients had copeptin concentrations below the 99th percentile at baseline. The median copeptin concentration was significantly increased at 30 min [16.0 pmol/L; interquartile range (IQR), 13.4-20.2 pmol/L], compared with the median baseline concentration (6.6 pmol/L; IQR, 5.3-8.3 pmol/L; P = 0.002). The copeptin concentration peaked 90 min after induction of myocardial infarction and returned to baseline concentrations (median, 8.2 pmol/L; IQR, 6.3-10.1) after 24 h, compared with the above baseline values (P = 0.06). Serum creatine kinase (CK) activities were significantly increased above baseline values by 1 day after TASH [median maximal postprocedural CK activity, 935.0 U/L (IQR, 545.5-1115.0 U/L); median baseline CK activity, 80.0 U/L (IQR, 63.5-109.0 U/L); P < 0.001]. CONCLUSIONS Our results provide additional evidence that early rule-out of suspected AMI is possible by using the copeptin concentration in combination with cardiac troponin T.
CPPNs Effectively Encode Fracture : A Response to Critical Factors in the Performance of HyperNEAT

This paper demonstrates that compositional pattern producing networks (CPPNs) can produce phenotypic patterns that exhibit fracture(i.e. discontinuities in patterns) and that when neural networks are evolved with CPPNs, as in the Hypercube-based NeuroEvolution of Augmenting Topologies (HyperNEAT) approach, the algorithm effectively incorporates hidden nodes to improve performance. These findings contradict those of a recent paper by van den Berg and Whiteson [51], to which this paper is in part a response. In particular, while van den Berg and Whiteson [51] report difficulty for HyperNEAT in several experimental domains, this paper provides counter-evidence suggesting that HyperNEAT in fact performs well in these domains. It also examines the reasons for the discrepancy, which is largely a result of implementation details. Building on this foundation of counter-evidence in the domains from van den Berg and Whiteson [51], the paper then shifts to refuting their central hypothesis, which is that patterns with fracture are problematic for CPPNs. This hypothesis is contradicted through the presentation of a wide variety of detailed examples of fracture 1 in CPPNs, suggesting that fracture in CPPNs may be the norm rather than the exception. In this way, this paper goes beyond examining particular experimental domains by highlighting the largely unexplored opportunity to study fracture in CPPN-based patterns, which can potentially initiate exciting future research into representation.

Prépublications Du Laboratoire a Version of the G-conditional Bipolar Theorem in L

Motivated by applications in financial mathematics, [3] showed that, although L(R+; Ω,F ,P) fails to be locally convex, an analogue to the classical bipolar theorem can be obtained for subsets of L(R+; Ω,F ,P) : if we place this space in polarity with itself, the bipolar of a set of non-negative random variables is equal to its closed (in probability), solid, convex hull. This result was extended by [1] in the multidimensional case, replacing R+ by a closed convex cone K of [0,∞)d, and by [12], who provided a conditional version in the unidimensional case. In this paper, we show that the conditional bipolar theorem of [12] can be extended to the multidimensional case. Using a decomposition result obtained in [3] and [1], we also remove the boundedness assumption of [12] in the one dimensional case and provide less restrictive assumptions in the multidimensional case. These assumptions are completely removed in the case of polyhedral cones K.
Optimization of the hop-byte metric for effective topology aware mapping

Suitable mapping of processes to the nodes of a massively parallel machine can substantially improve communication performance by reducing network congestion. The hop-byte metric has been used as a measure of the quality of such a mapping by several recent works. Optimizing this metric is NP hard, and thus heuristics are applied. However, the heuristics proposed so far do not directly try to optimize this metric. Rather, they use some intuitive methods for reducing congestion and use the metric just to evaluate the quality of the mapping. In fact, heuristics intending to optimize other metrics too don't directly optimize for them, but, rather, use the metric to evaluate the results of the heuristic. In contrast, we pose the mapping problem with the hop-byte metric as a quadratic assignment problem and use a heuristic to directly optimize for this metric. We evaluate our approach on realistic node allocations obtained on the Kraken system at NICS. Our approach yields values for the metric that are up to 75% lower than the default mapping and 66 % lower than existing heuristics. However, the time taken to produce the mapping can be substantially more, which makes this suitable for somewhat static, though possibly irregular, communication patterns. We introduce new heuristics that reduce the time taken to be comparable to that of existing fast heuristics, while still producing mappings of higher quality than existing ones. We also use theoretical lower bounds to suggest that our mapping may be close to optimal, at least for medium sized problems. Consequently, our work can also provide insight into the tradeoff between mapping quality and time taken by other mapping heuristics.
Recombinant FSH in alternative doses or versus urinary gonadotrophins for ovulation induction in subfertility associated with polycystic ovary syndrome: a systematic review based on a Cochrane review.

This paper is based on a Cochrane review published in The Cochrane Library, issue 2, 2001 (see www.CochraneLibrary. net for information) with permission from The Cochrane Collaboration and Update Software. Cochrane reviews are regularly updated as new evidence emerges and in response to comments and criticisms, and The Cochrane Library should be consulted for the most recent version of the review. This systematic review was performed to study the efficacy and safety of recombinant FSH (rFSH) versus urinary FSH (uFSH) and to compare different dose regimens of rFSH for ovulation induction in women with clomiphene-resistant polycystic ovary syndrome (PCOS). Six randomized controlled trials were included in the review, according to the principles of the Cochrane Menstrual Disorders and Subfertility Group. Three trials compared rFSH with uFSH and three trials compared two different treatment regimens of rFSH. Participants were women with clomiphene citrate-resistant PCOS. Main outcome measures were ovulation, clinical pregnancy, miscarriage, multiple pregnancy, ovarian stimulation syndrome (OSS), total gonadotrophin dose used and total duration of stimulation. Summary statistics were expressed as odds ratios. Data from the trials comparing rFSH and uFSH could be pooled. There was no evidence of a difference between rFSH and uFSH in any of the outcomes. Data from the trials comparing different dose regimens of rFSH could not be combined, and for each comparison there was insufficient evidence of a difference. More randomized clinical trials with sufficient power are necessary to estimate the difference, if one exists, between rFSH and uFSH and between different dose regimens of rFSH.
An Approach to Extracting Unexpected Patterns from Massive Attributes : Understanding of Condominium Purchasers ' Behavior through Data Mining May , 2002

Marketing analysis is an indispensable step to establish strategies for the condominium supply for developers. In this context, it is crucial to grasp the potential buyers’ behavioral characteristics as “rule” or “pattern” extracted from historical transaction data. The question that is often asked by developers is what kind of condominium customers are pursuing and who they are. So far, strategies in housing supply side rely mainly on the experience or intuition of the marketers/developers, and not from the comprehensive data analysis. In this paper, a new approach is demonstrated to extract informative and unexpected rules/patterns from a database with relatively small contract records but massive attributes. This approach can summarize information targeted to unexpected patterns in data structure using data mining methodology. For the validity of the proposed method, real data of about 800 condominium purchasers in Tokyo metropolitan area is analyzed. Our approach may contribute to develop the decision support systems that can provide managers with more innovative ideas from collected data in generating marketing strategies.
The Choice of Parameters in Arc Length Algorithm

To improve the efficiency of the arc length (AL) algorithm, the paper presents a quantitative method to choose the parameters of AL. The paper analyzes the condition to guarantee the correctness of AL, and gives the approaches to set the parameters. Moreover, the latency of AL under the new method is discussed in detail. The analysis and simulation shows that the latency of AL with the parameters chosen under the new method remains constant, while is not increasing as the size of network grows.
Painting on Moving Charts

In this paper we propose a system for painting on surfaces. This system is based on moving charts. At each moment, a local patch is selected on the surface. The patch is formed such that it covers an area on which an artist can easily paint. This patch can be subjected to move in either direction according to the artist’s request. For each patch, an optimized 2-D chart is generated and displayed to the user. The user can then paint on this chart. Texture, which is stored in a global atlas is updated due to the user modification. For our application, charts must have as little distortion as possible and chart boundaries should be as smooth and convex as possible. Therefore, we charfity local patches using a low-distortion parameterization while preserving the boundary convexity and smoothness.
Genetic Analysis of Genes Related to Tight Junction Function in the Korean Population with Non-Syndromic Hearing Loss

Tight junctions (TJs) are essential components of eukaryotic cells, and serve as paracellular barriers and zippers between adjacent tissues. TJs are critical for normal functioning of the organ of Corti, a part of the inner ear that causes loss of sensorineural hearing when damaged. To investigate the relation between genes involved in TJ function and hereditary loss of sensorineural hearing in the Korean population, we selected the TJP2 and CLDN14 genes as candidates for gene screening of 135 Korean individuals. The TJP2 gene, mutation of which causes autosomal dominant non-syndromic hearing loss (ADNSHL), lies at the DFNA51 locus on chromosome 9. The CLDN14 gene, mutation of which causes autosomal recessive non-syndromic hearing loss (ARNSHL), lies at the DFNB29 locus on chromosome 21. In the present study, we conducted genetic analyses of the TJP2 and CLDN14 genes in 87 unrelated patients with ADNSHL and 48 unrelated patients with either ARNSHL or potentially sporadic hearing loss. We identified two pathogenic variations, c.334G>A (p.A112T) and c.3562A>G (p.T1188A), and ten single nucleotide polymorphisms (SNPs) in the TJP2 gene. We found eight non-pathogenic variations in the CLDN14 gene. These findings indicate that, whereas mutation of the TJP2 gene might cause ADNSHL, CLDN14 is not a major causative gene for ARNSHL in the Korean population studied. Our findings may improve the understanding of the genetic cause of non-syndromic hearing loss in the Korean population.
PCA Based Generalized Interpolation for Image Super-Resolution

In this paper we propose an eigenimage based superresolution reconstruction technique. Eigenimages of a database of several similar low resolution images are obtained and the given low resolution image is projected on to the eigenimages to compute the eigenimage coefficients. The eigenimages are then interpolated using any conventional interpolation method and approximated to the nearest orthonormal bases. The high resolution image is reconstructed using these bases and the same coefficients determined as above. This method is applicable to images of a particular class and results are demonstrated for both face and fingerprint images. The algorithm offers significant advantage when the input image is blurred and noisy.
