Dirac and reduced quantization : A Lagrangian approach and application to coset spaces

A Lagrangian treatment of the quantization of first class Hamiltonian systems with constraints and Hamiltonian linear and quadratic in the momenta, respectively, is performed. The “first reduce and then quantize” and the “first quantize and then reduce” (Dirac’s) methods are compared. A source of ambiguities in this latter approach is pointed out and its relevance on issues concerning self-consistency and equivalence with the “first reduce” method is emphasized. One of the main results is the relation between the propagator obtained ti la Dirac and the propagator in the full space. As an application of the formalism developed, quantization on coset spaces of compact Lie groups is presented. In this case it is shown that a natural selection of a Dirac quantization allows for full self-consistency and equivalence. Finally, the specific case of the propagator on a two-dimensional sphere S2 viewed as the coset space SU(2)IU(l) is worked out.

A 18–40 GHz Substrate Integrated Waveguide H-Plane Horn Antenna

A 18–40 GHz wideband substrate integrated waveguide (SIW) H-plane horn antenna is proposed for applications on both the K- and Ka-bands. By employing a grating transition in front of the horn aperture, the impedance bandwidth (IBW) of the proposed antenna is broadened considerably. A broadband double-ridge waveguide (DRW)-to-SIW transition is also developed as the feeding structure for the proposed SIW H-plane horn antenna. The DRW is adopted to support a wider IBW as compared to that of a rectangular waveguide. A prototype of the proposed antenna is experimentally verified. The measured results show that the IBW for $|S_{11}| \leq -10$ dB ranges from 18 GHz to more than 40 GHz, covering the entire K- and Ka-bands. The measured gain varies from 7.52 to 15.37 dBi with an average gain of 11.58 dBi. In addition, the endfire radiation patterns are observed and maintained within the IBW.
Edinburgh Research Explorer Control of embryonic stem cells self-renewal and differentiation via coordinated splicing and translation of YY2

Translational control of gene expression plays a key role during early phases of embryonic development. Here we describe a novel regulator of mouse embryonic stem cells (mESCs), Yin-Yang 2 (YY2) that is controlled by the translation inhibitors, 4E-BPs. YY2 plays a critical role in regulating mESC functions through transcriptional control of key pluripotency factors, including Oct4 and Esrrb . Importantly, overexpression of YY2 directs the differentiation of mESCs into cardiovascular lineages. We show that the splicing regulator PTBP1 promotes the retention of an intron in the 5´ UTR of Yy2 mRNA, which confers sensitivity to 4E-BP-mediated translational suppression. Thus, we conclude that YY2 is a major regulator of mESC self-renewal and lineage commitment, and document a multilayer regulatory mechanism that controls its expression.
INfLUENCE Of POTASSIUM ON GROWTH, CONTENT Of MINERAL NUTRIENTS AND YIELD fORMATION Of THE SPRING BARLEY (HORDEUM VULGARE L.)

ZEHNaLEK, J., ADAM, V. , KIZEK, R. : Influence of potassium on growth, content of mineral nutri ents and yield formation of the spring barley (Hordeum vulgare L.). Acta univ. agric. et silvic. Mendel. Brun. , 2006, LIV, No. 1, pp. 145–154 In model experiment, an influence of increasing KCl doses on spring barley growth, accumulation of main mineral nutrients (N, P, K, Ca, Mg and Na) in main stalks, offshoots and roots and on yield for mation and its structure was observed. Increase of weight of above-ground parts of plants was inhibited only at the beginning of experiment by increasing KCl doses, particularly, significantly lower growth of offshoots, but on the other hand production of dry weight of roots was negatively influenced during whole cultivation. Accumulation of main mineral nutrients in the plants was mostly influenced at potassium. Uptake of potassium by plant increased up to 37%. Yield of kernels was higher at variants with application of KCl but the correlation between higher K doses and the yield increase has not been statistically proved. Increase in the yield was reached by higher number of offshoots, higher number of kernels and higher weight of kernels in comparison with control. Content of main mineral nutrients in kernel was not influenced by application of KCl, but potassium content in straw was significantly in creased.
Categories, Gender and Online Community

This article presents a sketch for a theory of the rhetorics involved in categorisation and the creation of culture in online communities. Persuasion, or shaping perceptions of the world, is never incidental to social life, but living online necessarily involves persuasion as it is difficult to bring force to bear, although people can be temporarily excluded from different groups to different degrees, and the modality of persuasion may be influenced by the structures of communication in play. Communication almost always involves an attempted act of power aiming to produce a response in another. It is argued that linguistic categories, especially self-identity categories, are to some extent flexible, and that they exist in connection and contrast with other categories. The meaning of categories depends upon the ways they are framed (frames can also be categories), and framing and category content can be the subject of argument. Among the most important ways of framing online by Westerners are by space, public/private, authenticity, gender and community. The rest of the article explores the nature of online communication and power; how gender is used as a category; the kinds of effects that this categorisation has had; and how this category becomes salient within the framework of people making a ‘community’ on the Cybermind mailing list.
iCub: Learning Emotion Expressions using Human Reward

The purpose of the present study is to learn emotion expression representations for artificial agents using reward shaping mechanisms. The approach takes inspiration from the TAMER framework for training a Multilayer Perceptron (MLP) to learn to express different emotions on the iCub robot in a human-robot interaction scenario. The robot uses a combination of a Convolutional Neural Network (CNN) and a Self-Organising Map (SOM) to recognise an emotion and then learns to express the same using the MLP. The objective is to teach a robot to respond adequately to the user's perception of emotions and learn how to express different emotions.

Functional data depth in Monte Carlo tests for spatial marked point processes

Author Henri Seijo Title Functional data depth inMonte Carlo tests for spatial marked point processes Instructor Ph.D. Mari Myllymäki Supervisor Prof. Aki Vehtari Thesis type Master’s thesis Degree programme Communications Engineering Date 2015-11-23 Language English Pages 61 Monte Carlo deviation tests are commonly utilized to test hypotheses concerning spatial point processes. Even though the classic deviation measures suffer from some inherent faults, namely spreading and asymmetry, they are still widely applied for such tests. In this thesis, I explore functional data depth as a novel alternative to classic deviation measures. To enable the use of modified band depth and modified half-region depth, I review the published algorithms, analyse the depth measures carefully and develop new algorithms for the necessary speedups and corrections. I conclude the thesis with two data examples and a discussion of the presented methods and other substitutes for classic deviation measures.
Species and population differences in social recognition between fishes: a role for ecology?

The social organization of animals is reliant on recognition. However, the precision and specificity with which an individual animal recognizes another in a social context, and the sensory mechanisms that it employs, may vary both within and between species. Differences in the ecology and in the mating systems of species may drive the evolution of different recognition abilities, ranging from individual-specific recognition to more general forms of recognition. We examined social recognition in two important model species in behavioral ecology, the guppy (Poecilia reticulata) and the three-spined stickleback (Gasterosteus aculeatus). We found that guppies were capable of individual recognition of conspecifics, as well as being able to differentiate between groups of conspecific based on cues relating to resource use and habitat use. By contrast, sticklebacks showed no ability to recognize individuals in a social context after prior interactions. Nonetheless, two out of three populations of sticklebacks demonstrated general recognition abilities, based on cues relating to resource use. We discuss the potential relationship between social recognition mechanisms and the ecological and life-history parameters of species and populations. Copyright 2009, Oxford University Press.
Performance of Printed Dipoles on Dual Band High-Impedance Surface

This paper investigates the characteristics of a printed dual band cross-dipole mounted on a High-Impedance Surface (HIS) designed for fLow = 2.4 GHz and fHi = 5.4 GHz. The HIS operates as an artificial magnetic conductor for both frequencies by using a rectangular periodic structure at a fixed distance of 1 mm. Thus, the farfield for both frequencies of the cross-dipole radiates with an increased gain in the upper hemisphere compared to free space dipoles, whereas in the back of the antenna geometry electronical components can be placed.
Detecting the Presence of Mixing with Multiscale Maximum Likelihood

A test of homogeneity tries to decide whether observations come from a single distribution or from a mixture of several distributions. A powerful theory has been developed for the case where the component distributions are members of an exponential family. When no parametric assumptions are appropriate, the standard approach is to test for bimodality, which is known not to be very sensitive for detecting heterogeneity. To develop a more sensitive procedure, this article builds on an approach employed in sampling literature and models the component distributions as logarithmically concave densities. It is shown how this leads to a special semiparametric model, in which the homogeneity problem is equivalent to testing whether a parameter c equals zero, versus the alternative that c > 0. This setup leads naturally to a novel multiscale maximum likelihood procedure, where the multiscale character reflects the desirable property of adaptivity to the unknown value of the parameter c under the alternative, to ensure a test with high power. The test can also be extended, in principle, to a multivariate situation. In a univariate setting, the multiscale procedure is well suited to computation with the iterative convex minorant algorithm, a recent innovation in computational nonparametric statistics. The test is applied to simulated data and to the stamp data of Izenman and Sommer.
Bounding Optimality Gap in Stochastic Optimization via Bagging: Statistical Efficiency and Stability

We study a statistical method to estimate the optimal value, and the optimality gap of a given solution for stochastic optimization as an assessment of the solution quality. Our approach is based on bootstrap aggregating, or bagging, resampled sample average approximation (SAA). We show how this approach leads to valid statistical confidence bounds for non-smooth optimization. We also demonstrate its statistical efficiency and stability that are especially desirable in limited-data situations, and compare these properties with some existing methods. We present our theory that views SAA as a kernel in an infinite-order symmetric statistic, which can be approximated via bagging. We substantiate our theoretical findings with numerical results.
Thermal Degradation Kinetics of Polysaccharides in Fibrous Materials during Hot Water Treatment: A Preliminary Study

The current Chinese Standard (GB5889-86 1986) for wet chemistry determination assumes that there is no temperature degradation of sugars during hot water extraction. There is therefore a need to quantify this level of error and propose possible solutions for future revisions. This research was performed to investigate the thermal resistance of polysaccharides in common fibrous materials. A two-factor, two-level experimental design was employed, in which pre-oven drying and water bath temperature were controlled and changes in extractive content were measured. The thermodynamic equations for polysaccharide thermal degradation in ramie and wood were calculated. High-performance liquid chromatography (HPLC) was employed to identify monosaccharide changes during the process. This study found that polysaccharides in fibrous materials have considerable thermal degradation during oven drying at 100 °C and hot water treatment. Lower temperature combinations are recommended during hot water extractive testing when sugar analysis is to be subsequently performed.
Effects of disturbance area on fouling communities from a tropical environment: Guanabara Bay, Rio de Janeiro, Brazil

In marine fouling communities, free space is one of the key limiting resources for settlement of new organisms. In this way, removing biomass through physical disturbances would play an important role in the structure and dynamics of these communities. The disturbance size seems to be a characteristic that influences recolonization patterns, thus affecting species diversity. The aim of this study was to analyze the effects of growing disturbance areas on fouling communities. Fouling panels were allowed to develop for 6 mo. at Guanabara Bay (22°52'S, 043°08'W) prior to a single application of randomly positioned, circular physical disturbances of growing areas (7 levels, from 0 to 75% removed cover, 10 replicates per treatment). Samples were taken fortnightly after the disturbance event, so as to follow the development patterns of the community afterward. At the first sampling the diversity showed maximum indices in communities to which intermediary disturbance levels were applied. However, this profile changed later to a diversity peak in communities with higher disturbance levels. It also showed a continuous increase in richness and diversity through time until the 7th sample (110 days after the disturbance event), with subsequent decrease. Such patterns seem to corroborate the Intermediate Disturbance Hypothesis, despite the drastic profile change with time, revealing that disturbance is indeed an important factor structuring hard bottom communities at Guanabara Bay, and highlighting the importance of longer term studies of disturbance impacts in marine communities.
TITLE : Combined Effects of Primary and Tertiary Blast on Rat Brain : Characterization of a Model of Blast-induced Mild Traumatic Brain Injury

The consequences of a mild traumatic brain injury can be especially severe if it is repeated within the period of increased cerebral vulnerability (ICV) that follows the initial insult. To better understand the molecular mechanisms that contribute to ICV, we exposed rats to mild blast overpressure at a rate of 1 per 30 min (a total of 5 exposures), monitored select physiological parameters, and assessed their behavior. Two days post-injury or sham, we determined changes in protein biomarkers related to various pathologies in behaviorally-relevant brain regions as well as in the plasma. We found that oxygen saturation and heart rate were transiently depressed following mild blast exposure and that injured rats exhibited significantly increased anxietyand depression-related behaviors. Proteomic analyses of the selected brain regions showed evidence of substantial oxidative stress and vascular changes, altered cell adhesion, inflammation, as well as neuronal and glial cell loss/damage predominantly in the prefrontal cortex; similar pathological changes were detected in the plasma of injured rats. Our findings indicate that repeated mild blast exposure induces complex molecular pathomechanisms that can be detected in the peripheral blood. The validation and subsequent use of these markers can help identify at-risk individuals and the period of ICV.
SPONTANEOUS RESOLUTION OF PRIMARY AND RECURRENT CYSTIC HYGROMA FOLLOWING ACUTE INFECTION

Introduction: There are reports of chronic infection leading to spontaneous regression of primary cystic hygromas (CH). To the best of our knowledge there is no report of acute infection in primary and recurrent CH leading to a rapid and spontaneous resolution. We report case series of four patients with primary (three) and recurrent (one) CH, which resolved spontaneously following an episode of acute infection within a short span of 1-2 weeks. Patients and Methods: A retrospective case note review of four cases of CH was done in two tertiary paediatric surgical centres in UK. Results: Four-year-old boy presented with CH in the axilla. It recurred within 3 weeks of surgical excision. He developed acute infection in the recurrent CH while waiting for sclerotherapy. This was treated with oral antibiotics and led to complete resolution of the swelling within a week. Follow up was 3 months. A neonate presented with congenital left sided CH in the neck. On day 9 of life there was an infection in the CH, which was treated with intravenous antibiotics. There was a complete resolution of the neck swelling within 2 week. Follow up was 12 years. A 2-month-old girl presented with right-sided CH in her neck. A decision was made to treat it conservatively. The CH got infected at 6 months of age while on conservative management. It was treated with intravenous antibiotics. There was a complete resolution of the neck mass in 2 weeks. Follow up was 2 years. A neonate presented with congenital right neck CH. Sclerotherapy was planned at 6 months of age. The infant developed an acute infection in CH at 4 weeks, requiring intravenous antibiotics. There was complete resolution of CH within weeks. Follow up was 1 year. Conclusion: This case series raises our awareness of spontaneous resolution of primary as well as recurrent cystic hygromas following acute infection.

AN INVERSE CURVATURE FLOW IN A SPACETIME WITH A FUTURE SINGULARITY

We consider an inverse curvature flow (ICF) (0.1) ẋ = −F−1ν in a Lorentzian manifold N with a certain future singularity, which is still quite general. Here, F denotes a curvature function of class (K∗), which is homogeneous of degree one, e.g. the n-th root of the Gaussian curvature, and ν the past directed normal. We prove longtime existence of the ICF and that the leaves of the ICF provide a foliation of the future of the initial flow hypersurface.
Long Run Returns Predictability and Volatility with Moving Averages

This paper examines how the size of the rolling window, and the frequency used in moving average (MA) trading strategies, affects financial performance when risk is measured. We use the MA rule for market timing, that is, for when to buy stocks and when to shift to the risk-free rate. The important issue regarding the predictability of returns is assessed. It is found that performance improves, on average, when the rolling window is expanded and the data frequency is low. However, when the size of the rolling window reaches three years, the frequency loses its significance and all frequencies considered produce similar financial performance. Therefore, the results support stock returns predictability in the long run. The procedure takes account of the issues of variable persistence as we use only returns in the analysis. Therefore, we use the performance of MA rules as an instrument for testing returns predictability in financial stock markets.
Long Non-Coding RNA in Non-Small Cell Lung Cancers

Non-small cell lung cancer (NSCLC) accounts for nearly 80% of diagnosed lung can- cers. Due to the predominantly late diagnosis of NSCLC and drug resistance in the targeted therapy approaches, the 5-year overall survival rate is still less than 19%. Thus, novel diagnosis and treatment approaches are needed. Many efforts have been made to achieve great progress in understanding the genomic landscape of NSCLC and the molecular mechanisms involved in tumorigenesis. Long non-coding RNAs (lncRNAs) are transcripts longer than 200 nucleotides with little or no protein-coding potential. They are encoded across the genome and are involved in a wide range of cellular and biological processes. Dysregulation of lncRNAs is associated with a number of cancer- related processes, including epigenetic regulation, microRNA silencing, and DNA dam-age. Furthermore, lncRNAs have been reported to have the potential as biomarker for diagnosis and prognosis, as well as the therapy targets. Here in this chapter, we review some well-characterized lncRNAs associated with NSCLCs and the potential of lncRNAs as biomarkers in the diagnosis and prognosis of NSCLCs.
A Bio-inspired Multi-Robot Coordination Approach

In this paper, a bio-inspired stigmergy-based coordination approach is proposed for a distributed multi-robot system. This approach is inspired from the behavior of social insect swarming, where social insect colonies are able to build sophisticated structures and regulate the activities of millions of individuals by endowing each individual with simple rules based on local perception. A virtual pheromone mechanism is proposed as the message passing coordination scheme among the robots. The proposed algorithm has been implemented on embodied robot simulator Player/Stage, and the simulation results show the feasibility, robustness, and scalability of the methods under different dynamic environments with real-world constraints.
Adaptive Fuzzy Control of Nonlinear Systems Based on T-S fuzzy Hyperbolic Model

In this paper, a design scheme is proposed for a class of nonlinear systems, which can be modeled by a T-S fuzzy hyperbolic model of stable fuzzy control. Firstly, the parallel distributed compensation (PDC) method is employed to design the fuzzy controller for the system without considering the error caused by fuzzy modeling, and the sufficient conditions of stability are given by using linear matrix inequalities (LMI). Then the error caused by fuzzy modeling is considered and the method of adaptive control is employed to reduce the effect of the modeling error. Simultaneously, the closed-loop system has better dynamic performance. According to Lyapunov stability theory, the resulting closed-loop system is proved to be asymptotically stable. Finally, an illustrative example is given to verify the effectiveness of the results proposed in this paper.
