Pattern Classiication with the Bcm Neural Network

Synaptic weights of the model neurons in our selforganizing artiicial neural network (ANN) modify according to the Bienenstock, Cooper and Munro (BCM) unsupervised learning algorithm. What makes the BCM rules diierent from any other learning procedure is the dynamic synaptic mod-iication threshold M , which determines whether a neuron's activity at any moment will lead to strengthening or weakening of its synaptic weights. We design , perform and discuss several pilot experiments with the 2D alphanumeric pattern classiication in order to investigate the computational properties of the BCM neural network with the so called feedforward inhibition.
Chirp signal-based aerial acoustic communication for smart devices

Smart devices such as smartphones and tablet/wearable PCs are equipped with voice user interface, i.e., speaker and microphone. Accordingly, various aerial acoustic communication techniques have been introduced to utilize the voice user interface as a communication interface. In this paper, we propose an aerial acoustic communication system using inaudible audio signal for low-rate communication in indoor environments. By adopting chirp signal, which is widely used for radar applications due to its capability of resolving multi-path propagation, the proposed acoustic modem supports long-range communication independent of device characteristics over severely frequency-selective acoustic channel. We also design a backend server architecture to compensate for the low data rate of chirp signal-based acoustic modem. Via extensive experiments, we evaluate various characteristics of the proposed modem including multi-path resolution and multiple chirp signal detection. We also verify that the proposed chirp signal can deliver data at 16 bps in typical indoor environments, where its maximum transmission range is drastically extended up to 25 m compared to the few meters of the previous research.
Semiclassical and quantum field theoretic bounds for traversable Lorentzian stringy wormholes

A lower bound on the size of a Lorentzian wormhole can be obtained by semiclassically introducing the Planck cutoff on the magnitude of tidal forces (Horowitz-Ross constraint). Also, an upper bound is provided by the quantum field theoretic constraint in the form of the Ford-Roman Quantum Inequality for massless minimally coupled scalar fields. To date, however, exact static solutions belonging to this scalar field theory have not been worked out to verify these bounds. To fill this gap, we examine the wormhole features of two examples from the Einstein frame description of the vacuum low energy string theory in four dimensions which is the same as the minimally coupled scalar field theory. Analyses in this paper support the conclusion of Ford and Roman that wormholes in this theory can have sizes that are indeed only a few order of magnitudes larger than the Planck scale. It is shown that the two types of bounds are also compatible. In the process, we point out a "wormhole" analog of naked black holes.
Effects of some diseases on the quality of culinary soybean seed

It has been estimated that diseases reduce the world’s annual soybean production by 11% per year (≈ 15 million t). The most serious diseases are considered to be, in order of importance, soybean cyst nematode caused by Heterodera glycines, stem canker (Diaporthe phaseolorum), brown spot (Septoria glycines), charcoal rot (Macrophomina phaseolina), purple stain (Cercospora kikuchii) and sclerotinia blight (Sclerotinia sclerotiorum) (Sinclair and Hartman, 1999a). Australia is free from soybean cyst nematode and brown spot.
Quantitative Stochastic Analysis of Magnetic Resonance Images of the Brain

The aim of our work is to perform an automated tool for brain MRI tissues quantification. The method we develop is based on MRI intensity stochastic analysis. By the use of the Gaussian mixture model for these intensities, we estimate MRI tissues parameters with a combination of the expectation-maximization algorithm and the Markov random field model witch provide contextual constraints that improve the classification of image pixels into three classes of tissue: white matter, grey matter and cerebro-spinal fluid. The automated model based algorithm is also extended to take in account an important MRI artefact: the bias field caused by electromagnetic field inhomogeneities. The resulting automated MRI analysis method simultaneously corrects from MR field inhomogeneities, estimates tissue classes distribution parameters, classifies the image and detects multiple sclerosis lesions when treated images present this pathology. We validate our method on simulated data then on real MRI scans
A multi-resolution scheme ICP algorithm for fast shape registration

The iterative closest point (ICP) algorithm is widely used for the registration of geometric data. One of its main drawbacks is its quadratic time complexity O(N/sup 2/) with the shape number of points N, which implies long processing time, especially when using high resolution data. This paper proposes to accelerate the process by a coarse to fine multiresolution approach in which a solution at a coarse level is successively improved at a finer level of representation. Specifically, it investigates this multiresolution ICP approach when coupled with the tree search or the neighbor search closest point algorithms. A theoretical and practical analysis and a comparison of the considered algorithms are presented. Confirming the success of the multiresolution scheme, the results also show that this combination permits us to create a very fast ICP algorithm, gaining speed up to a factor of 27 over a standard fast ICP algorithm.
on the Ward BRDF

The anisotropic BRDF introduced in [Ward 1992] has become widely used in computer graphics, but some important implementation details are less widely known. We discuss how to efficiently evaluate the Ward BRDF. Then we derive the probability density function for its associated Monte Carlo sampling scheme and the correct weights to use with the generated samples. Finally for the isotropic version, we describe how to bound the maximum possible BRDF value over a region of (direction) space.
Drug-induced hypercalcemia / hypercalciuria causes polyuria and reduces AQP 2 expression in rats

Trafficking of water channel aquaporin-2 (AQP2) to the apical membrane is critical to water reabsorption in renal collecting ducts and its regulation maintains body water homeostasis. However, exact molecular mechanisms which recruit AQP2 are unknown. Recent studies highlighted a key role for spatial and temporal regulation of actin dynamics in AQP2 trafficking. We have recently identified AQP2-binding proteins which directly regulate this trafficking: SPA-1, a GTPase-activating protein (GAP) for Rap1, and cytoskeletal protein actin. In addition, a multiprotein “force generator” complex which directly binds to AQP2 has been discovered. This review summarizes recent advances related to the mechanism for AQP2 trafficking. © 2006 Elsevier B.V. All rights reserved.
Progress on the relativistic klystron two-beam accelerator prototype

The technical challenge for making two-beam accelerators into realizable power sources lies in the creation of the drive beam and in its propagation over long distances through multiple extraction sections. This year we have been constructing a 1.2-kA, 1-MeV, electron induction prototype injector as a collaborative effort between LBL and LLNL. The electron source will be a 3.5″-diameter, thermionic, flat-surface cathode with a maximum shroud field stress of approximately 165 kV/cm. Additional design parameters for the injector include a pulse length of over 120-ns flat top (1% energy variation), and a normalized edge emittance of less than 200 π-mm-mr. Planned diagnostics include an isolated cathode with resistive divider for direct measurement of current emission, resistive-wall and magnetic probe current monitors for measuring beam current and centroid position, capacitive probes for measuring A-K gap voltage, an energy spectrometer, and a pepper-pot emittance diagnostic. Details of the injector, beam l.
FORMULATION OF MULTIPLE FLOATING DRUG DELIVERY

Dept. of Pharm. Sciences. , M.D. Uniersity Rohtak Page 180 6. FORMULATION OF MULTIPLE FLOATING DRUG DELIVERY SYSTEM Floating systems are low-density systems that have sufficient buoyancy to float over the gastric contents and remain in the stomach for a prolonged period. While the system floats over the gastric contents, the drug is released slowly at the desired rate which results in increased GRT and reduces fluctuation in plasma drug concentration (Chawala et al., 2003). After release of drug, the residual system is emptied from the stomach (Mayavanshi & Gajjar, 2008).
A Note on Mean-variance Analysis of the Newsvendor Model with Stockout Cost

We apply the mean-variance approach to analyze the risk-averse newsvendor problem with stockout cost. We ﬁrst derive an explicit form and some new properties of the variance of the proﬁt function. Then, under the assumption that demand follows the power distribution, and its special case the uniform distribution, we obtain the set of optimal ordering quantities. We also give a counterexample to one result presented in the literature. Contrary to the traditional result in the literature that the risk-averse newsvendor always orders less than the risk-neutral newsvendor, our ﬁndings show that this may not be the case when stockout cost is considered because the newsvendor may order more than the risk-neutral newsvendor order quantity under a stockout situation with mean-variance tradeoﬀ.
Unraveling the Intersecting Meanings of Interpersonal Violence: The Embodiment of Gender and Race in Attributions and Characterizations of Violence

ABSTRACT We examine the meaning of interpersonal violence using labeling and embodiment perspectives. We systematically explore the process of marginalization from the vantage point of college students. Using one-on-one interviews, we report on the characterizations and origin of labels used to describe those perceived to engage in violent behavior. Grounded theory is employed to inductively develop hypotheses. Three themes emerged: The Embodiment of Violence; The Deviance of (White) Women’s Violence; and The Enduring Stereotype of (Black) Male Violence. We discuss the process used to impugn gendered and raced meanings upon violence. We delineate how assumptions about gender, race/ethnicity and the body influence e marginalization process. Knowledge-sources used to base judgments about behavior and group membership are identified. We add to labeling and embodiment perspectives while broadening the understanding of labels associated with violent offenders and their origin.
Notch Is a Critical Component of the Mouse Somitogenesis Oscillator and Is Essential for the Formation of the Somites

Segmentation of the vertebrate body axis is initiated through somitogenesis, whereby epithelial somites bud off in pairs periodically from the rostral end of the unsegmented presomitic mesoderm (PSM). The periodicity of somitogenesis is governed by a molecular oscillator that drives periodic waves of clock gene expression caudo-rostrally through the PSM with a periodicity that matches somite formation. To date the clock genes comprise components of the Notch, Wnt, and FGF pathways. The literature contains controversial reports as to the absolute role(s) of Notch signalling during the process of somite formation. Recent data in the zebrafish have suggested that the only role of Notch signalling is to synchronise clock gene oscillations across the PSM and that somite formation can continue in the absence of Notch activity. However, it is not clear in the mouse if an FGF/Wnt-based oscillator is sufficient to generate segmented structures, such as the somites, in the absence of all Notch activity. We have investigated the requirement for Notch signalling in the mouse somitogenesis clock by analysing embryos carrying a mutation in different components of the Notch pathway, such as Lunatic fringe (Lfng), Hes7, Rbpj, and presenilin1/presenilin2 (Psen1/Psen2), and by pharmacological blocking of the Notch pathway. In contrast to the fish studies, we show that mouse embryos lacking all Notch activity do not show oscillatory activity, as evidenced by the absence of waves of clock gene expression across the PSM, and they do not develop somites. We propose that, at least in the mouse embryo, Notch activity is absolutely essential for the formation of a segmented body axis.
THE POTENTIALS OF URBAN FARMING TECHNOLOGY IN MALAYSIA: POLICY INTERVENTIONSThe Potential of Urban Farming Technology in Malaysia: Policy Intervention

Urban fFarming is a cultivation practice where food is produced in the cities and areas around existing town areas (Bailkey and Nasr, 2000). Generally, urban farming is not a new concept in Malaysia. The similar concept of farming activities adopted by urban folks surrounding residential areashome started a long time ago. This type of cultivation has been widely named with various contextual contexts of urban farming, or urban agriculture or home gardening are in place. This home garden is practiced as a hobby, source of fruits and vegetables for the households and in some instances become anearn extra income for them.household members. A typical Malaysian cultural trait is sharing the harvest with neighbors and community. Nowadays, urban farming has been used to replace home gardening hobby, and this activity has changed its role in relation to the socio-demographic changes and needs. This is due to the agriculture agricultural land issue, urbanization, urban poverty and business opportunity opportunities that emerged from the socio-economic needs. The uUrban farming is getting in-placemore and more popular in many regions across the world. New York, London and Tokyo are the leading cities from the developed countries which emphasis emphasize on the various practices of urban farming. This is followed by the developing countries such as Singapore from which the urban farming contributes almost 25% of its food supply. All countries engaged with the urban farming are now had to deal with input constraints for instancelike spaces, water, managing and maintaining the farming system in the high density populated areas. Therefore, there is a need to investigate the awareness and the understanding of the urban population toward urban farming technology. Furthermore, it is important to identify which technology is preferred by the urban population, especially the organizations that have the intention to implement the urban farming at their premise.

A thermal oscillation under a restorative forcing

The authors report an interdecadal oscillation in a wind‐ and thermally‐driven ocean general circulation model (OGCM). The oscillation is tantalizing in that it occurs under a relatively strong thermal damping (26.3 W m−2 K−1). Examinations involving a two‐dimensional OGCM, a simple thermal ‘flip–flop’ model, and a three‐dimensional OGCM with and without the nonlinear effect of temperature in the state equation of sea water demonstrate that the oscillation is not driven by mechanisms such as the so‐called convective oscillator, or the advective overshooting oscillator. Instead, the oscillation is associated with the propagation of modelled long Rossby‐waves with westward phase velocity. It is found that the north–south basin extent of the OGCM is an important factor; a larger north–south basin extent is conducive to the generation of thermal wind flows crucial for initiating the propagation of disturbances. The geophysical relevance of these results is discussed.
Microsatellite Instability and Colorectal Cancer Prognosis

Purpose: Many studies have evaluated the role of high levels of microsatellite instability (MSI) as a prognostic marker and predictor of the response to chemotherapy in colorectal cancer (CRC); however, the results are not conclusive. The aim of this study was to analyze the prognostic significance of high levels of MSI (MSI-H) in CRC patients in relation to fluorouracil-based chemotherapy. Experimental Design: In three different institutions, 1,263 patients with CRC were tested for the presence of MSI, and CRC-specific survival was then analyzed in relation to MSI status, chemotherapy, and other clinical and pathologic variables. Results: Two hundred and fifty-six tumors were MSI-H (20.3%): these were more frequently at a less advanced stage, right-sided, poorly differentiated, with mucinous phenotype, and expansive growth pattern than microsatellite stable carcinomas. Univariate and multivariate analyses of 5-year–specific survival revealed stage, tumor location, grade of differentiation, MSI, gender, and age as significant prognostic factors. The prognostic advantage of MSI tumors was particularly evident in stages II and III in which chemotherapy did not significantly affect the survival of MSI-H patients. Finally, we analyzed survival in MSI-H patients in relation to the presence of mismatch repair gene mutations. MSI-H patients with hereditary non–polyposis colorectal cancer showed a better prognosis as compared with sporadic MSI-H; however, in multivariate analysis, this difference disappeared. Conclusions: The type of genomic instability could influence the prognosis of CRC, in particular in stages II and III. Fluorouracil-based chemotherapy does not seem to improve survival among MSI-H patients. The survival benefit for patients with hereditary non–polyposis colorectal cancer is mainly determined by younger age and less advanced stage as compared with sporadic MSI-H counterpart.
Performance of setaria in the northern North Island

Setaria sphacelata is a perennial C, grass that has high potential summer yield, but its persistence and cool-season production are poor. An experiment investigated whether a winter oats cover crop could negate these poor traits. While oversowing oats into established setaria increased total winter-spring herbage production, the use of a cover crop reduced setaria persistence despite minimum soil temperatures being 1.5”C higher. Starch and soluble sugar levels in three different leaf and stem fractions of setaria were low and showed little seasonal variation. S. sphacelata and S. neglecta plants that had survived previous evaluations were transplanted into a field nursery and screened for a further 3 years. From this nursery, blocks of four phenotypically different lines were then established and their performance (herbage production and quality) was assessed for 2 years. Mean annual yields of the more productive blocks were 12.5 t /ha, 60% of this occurring during January-March. Herbage quality was assessed as being low-medium, leaf in vitro digestibilities and crude protein being 70% and 12% respectively. Within this “persistent” population, soluble sugars in the basal fractions of the plant appear important in assisting cool-season persistence. The place of a perennial C, grass such as setaria in farm systems was investigated using the computer model Stockpol. A smsll specialist block of setaria may have merit for feeding breeding stock where there is a need to miriimise the risk of drought in northern zones of New Zealand.
The neural correlates of blushing : Piloting an elicitation protocol

Blushing is a physiological response to emotional stimuli, caused by the vasodilation of cutaneous blood vessels. This response is typically associated with the social, self-conscious emotion of embarrassment and is often a primary complaint of patients diagnosed with social anxiety disorder. Although previous studies have investigated blushing in relation to social anxiety, no study has yet explored the neural correlates of blushing. This research was a pilot study aimed at developing an elicitation protocol for blushing that is both reliable and transferable to an MRI scanner environment. Participants were 25 females between the ages of ages of 18 and 25 years. They were assessed using the MINI neuropsychiatric interview, Modigliani’s Embarrassability Scale, the Liebowitz Social Anxiety Scale, Blushing Propensity Scale (BPS), and the Blushing, Trembling, and Sweating Questionnaire (BTS-Q). Blushing was elicited by video recording the participants singing and then playing their performance back to them. The protocol followed an AB block design, using the performance of a professional singer as a baseline. Blushing elicitation was confirmed with 2 physiological measures: heart rate (HR) and galvanic skin response (GSR), both measured by an ambulatory psychophysiological monitoring system. Visual analogue scales (VAS) were used to obtain subjective measures on participants’ rating of embarrassment and perception of their blush response, and the researcher’s visual confirmation of the blush response. The protocol successfully elicited blushing, as measured by HR and GSR and the self-report and researcher VAS. Based on correlations with the physiological and subjective confirmations of blushing, the BPS and BTS-Q were identified as pre-screening measures to eliminate individuals that may not blush readily. This successful protocol can be transferred to a scanner environment for a pioneering fMRI study to determine the neural correlates of blushing.
THIXOTROPY-ENHANCING AGENT – A KEY COMPONENT TO REDUCE FORMWORK PRESSURE OF SCC

A comprehensive research program was undertaken to evaluate the effect of concentration and type of thickening agents on the variations in lateral pressure that can be developed by self-consolidating concrete (SCC). Three conventional viscosityenhancing agents (VEA), including a liquid polysaccharide, a powder polysaccharide, and a cellulose-based VEA as well a thixotropy-enhancing agent (TEA) were tested. All mixtures had similar initial slump flow of 650 ± 15 mm. The concrete was cast in an experimental column measuring 2800 mm in height to monitor variations in lateral pressure using a series of pressure sensors. Irrespective of the thickener in use, the incorporation of VEA or TEA at low concentration is shown to increase the rate of pressure drop with time compared to reference mixtures made without any thickener. Further increase in the concentration of conventional VEA can lead to reduced rate of pressure drop given the increase demand in high-range water-reducing admixture (HRWRA), which enhances fluidity retention. Unlike conventional VEA, the increase in TEA content decreases the initial maximum pressure as well as the rate of pressure drop. Combination of powder polysaccharide or cellulose-based VEA with TEA at low concentration was found to reduce the maximum lateral pressure and increase the rate of pressure drop compared to mixtures SCC containing VEA only at similar concentration. The incorporation of VEA/TEA combination resulted also in better fluidity retention.
