Stability in Nonautonomous Dynamics: A Survey of Recent Results

We discuss recent results in the stability theory of nonautonomousdifferential equations under sufficiently small perturbations.We mostly concentrate on the description of our own work, with emphasison the Lyapunov stability of solutions, the existence and smoothnessof invariant manifolds, and the construction and regularity of topologicalconjugacies, among other topics. The main novelty is that we alwaysconsider a nonuniform exponential behavior of the linear variationalequations, given either by the existence of a nonuniform exponentialcontraction or a nonuniform exponential dichotomy.
Attributing and denying humanness to others

We review a programme of research on the attribution of humanness to people, and the ways in which lesser humanness is attributed to some compared to others. We first present evidence that humanness has two distinct senses, one representing properties that are unique to our species, and the other—human nature—those properties that are essential or fundamental to the human category. An integrative model of dehumanisation is then laid out, in which distinct forms of dehumanisation correspond to the denial of the two senses of humanness, and the likening of people to particular kinds of nonhuman entities (animals and machines). Studies demonstrating that human nature attributes are ascribed more to the self than to others are reviewed, along with evidence of the phenomenon's cognitive and motivational basis. Research also indicates that both kinds of humanness are commonly denied to social groups, both explicitly and implicitly, and that they may cast a new light on the study of stereotype content. Our approach to the study of dehumanisation complements the tradition of research on infrahumanisation, and indicates new directions for exploring the importance of humanness as a dimension of social perception.
Thermal Tracking of Sports Players

We present here a real-time tracking algorithm for thermal video from a sports game. Robust detection of people includes routines for handling occlusions and noise before tracking each detected person with a Kalman filter. This online tracking algorithm is compared with a state-of-the-art offline multi-target tracking algorithm. Experiments are performed on a manually annotated 2-minutes video sequence of a real soccer game. The Kalman filter shows a very promising result on this rather challenging sequence with a tracking accuracy above 70% and is superior compared with the offline tracking approach. Furthermore, the combined detection and tracking algorithm runs in real time at 33 fps, even with large image sizes of 1920 × 480 pixels.
So what do managers say about classroom management?

The context of this article was that, after researching issues of classroom management for a number of years, I was asked by managers at different institutions to speak to their staff about strategies for helping to counteract the problems tutors faced in many classes on a day-to-day basis. The question that emerged was how might managers in the lifelong learning sector support tutors in dealing with these stressful situations. The methodology of this inquiry was to offer qualitative practitioner research which would suggest some recommendations to improve practice on how managers might support teachers in these circumstances. The research methods would aim to determine managers’ perspectives, using a survey to identify a sample of their views. This would lead to two focus groups with managers, opening up a more exploratory discussion, followed by an in-depth interview with an experienced, particularly supportive manager, working with challenging classes. The purpose of this interview was to review a range of strategies that might be used to help managers support staff and students create more effective learning environments. The next stage was to subject managers’ suggestions to the views of teachers. The findings from this research showed there were widespread problems in many classes where this research took place. Managers offered a range of localised and wider strategies for supporting teachers in these challenging situations. Offering whole institution approaches, training on interventions and opening spaces for tutors and managers to explore these issues in a blame-free environment were some of the recommendations. The tutors surveyed welcomed these suggestions.
Particle location based on Circular Hough Transform and Quadrant Radius Histogram

This paper presents a method for particle location based on Circular Hough Transform and Quadrant Radius Histogram in Particle Image Velocimetry. Different from the existing approaches, 2D Gaussian function is not used to describe the particle intensity profile because of defocusing. In proposed method, Circular Hough Transform was employed to detect the particle and calculate the initial particle center coordinate, and then the Quadrant Radius Histogram was applied to modify the initial particle center coordinate more accurately. Experiments on real particle images have demonstrated the feasibility of the proposed method for focused and defocused particle location, and the mean MAE of the distance between the estimated particle center and the real particle center for all experimental particle images is about 0.624 pixels.

Anesthesia management for MitraClip device implantation.

AIMS AND OBJECTIVES Percutaneous MitraClip implantation has been demonstrated as an alternative procedure in high-risk patients with symptomatic severe mitral regurgitation (MR) who are not suitable (or) denied mitral valve repair/replacement due to excessive co morbidity. The MitraClip implantation was performed under general anesthesia and with 3-dimensional transesophageal echocardiography (TEE) and fluoroscopic guidance. MATERIALS AND METHODS Peri-operative patient data were extracted from the electronic and paper medical records of 21 patients who underwent MitraClip implantations. RESULTS Four MitraClip implantation were performed in the catheterization laboratory; remaining 17 were performed in the hybrid operating theatre. In 2 patients, procedure was aborted, in one due to migration of the Chiari network into the left atrium and in second one, the leaflets and chords of the mitral valve torn during clipping resulting in consideration for open surgery. In the remaining 19 patients, MitraClip was implanted and the patients showed acute reduction of severe MR to mild-moderate MR. All the patients had invasive blood pressure monitoring and the initial six patients had central venous catheterization prior to the procedure. Intravenous heparin was administered after the guiding catheter was introduced through the inter-atrial septum and activated clotting time was maintained beyond 250 s throughout the procedure. Protamine was administered at the end of the procedure. All the patients were monitored in the intensive care unit after the procedure. CONCLUSIONS Percutaneous MitraClip implantation is a feasible alternative in high-risk patients with symptomatic severe MR. Anesthesia management requirements are similar to open surgical mitral valve repair or replacement. TEE plays a vital role during the MitraClip implantation.
NO modulates fetoplacental blood flow distribution and whole body oxygen extraction in fetal sheep

Smolich, Joseph J. NO modulates fetoplacental blood flow distribution and whole body oxygen extraction in fetal sheep. Am. J. Physiol. 274 (Regulatory Integrative Comp. Physiol. 43): R1331–R1337, 1998. —It is unknown if nitric oxide (NO) influences the relative level of the left (LV) and right ventricular (RV) outputs, the blood flow distribution between the body and placenta, or whole body O2 extraction and O2 consumption in the fetus. To address these questions eight fetal lambs were chronically instrumented at 128–134 days gestation (term 147 days), and blood flows were measured with radioactive microspheres 3–4 days later at baseline and after inhibition of NO synthesis with Nv-nitro-Larginine (L-NNA, 10 and 25 mg/kg iv). L-NNA progressively reduced the combined ventricular output (P , 0.005) but did not alter the relative levels of the LV and RV outputs. Fetal body blood flow fell by 31% after 10 mg/kg L-NNA (P , 0.005), but a reduction in placental blood flow (P , 0.005) was smaller (20%) and not observed until 25 mg/kg L-NNA. Whole body O2 extraction increased by 71% after 10 mg/kg L-NNA (P , 0.005) and did change further at 25 mg/kg L-NNA, whereas whole body O2 consumption rose by 15% at 10 mg/kg L-NNA (P , 0.05) and returned to baseline at 25 mg/kg L-NNA. These results suggest that, as well as reducing the combined ventricular output, inhibition of fetal NO synthesis redistributes systemic blood flow toward the placenta and increases fetal body O2 extraction. The latter initially increases whole body O2 consumption and then maintains it at near baseline levels after a fall in placental perfusion.
Role of Aquaporin-4 in Airspace-to-Capillary Water Permeability in Intact Mouse Lung Measured by a Novel Gravimetric Method

The mammalian peripheral lung contains at least three aquaporin (AQP) water channels: AQP1 in microvascular endothelia, AQP4 in airway epithelia, and AQP5 in alveolar epithelia. In this study, we determined the role of AQP4 in airspace-to-capillary water transport by comparing water permeability in wild-type mice and transgenic null mice lacking AQP1, AQP4, or AQP1/AQP4 together. An apparatus was constructed to measure lung weight continuously during pulmonary artery perfusion of isolated mouse lungs. Osmotically induced water flux (Jv) between the airspace and capillary compartments was measured from the kinetics of lung weight change in saline-filled lungs in response to changes in perfusate osmolality. Jv in wild-type mice varied linearly with osmotic gradient size (4.4 × 10−5 cm3 s−1 mOsm−1) and was symmetric, independent of perfusate osmolyte size, weakly temperature dependent, and decreased 11-fold by AQP1 deletion. Transcapillary osmotic water permeability was greatly reduced by AQP1 deletion, as measured by the same method except that the airspace saline was replaced by an inert perfluorocarbon. Hydrostatically induced lung edema was characterized by lung weight changes in response to changes in pulmonary arterial inflow or pulmonary venous outflow pressure. At 5 cm H2O outflow pressure, the filtration coefficient was 4.7 cm3 s−1 mOsm−1 and reduced 1.4-fold by AQP1 deletion. To study the role of AQP4 in lung water transport, AQP1/AQP4 double knockout mice were generated by crossbreeding of AQP1 and AQP4 null mice. Jv were (cm3 s−1 mOsm−1 × 10−5, SEM, n = 7–12 mice): 3.8 ± 0.4 (wild type), 0.35 ± 0.02 (AQP1 null), 3.7 ± 0.4 (AQP4 null), and 0.25 ± 0.01 (AQP1/AQP4 null). The significant reduction in P f in AQP1 vs. AQP1/AQP4 null mice was confirmed by an independent pleural surface fluorescence method showing a 1.6 ± 0.2-fold (SEM, five mice) reduced P f in the AQP1/AQP4 double knockout mice vs. AQP1 null mice. These results establish a simple gravimetric method to quantify osmosis and filtration in intact mouse lung and provide direct evidence for a contribution of the distal airways to airspace-to-capillary water transport.
A Family of Distributed Space-Time Trellis Codes AchievingFull Diversity for Asynchronous Cooperative Communications

In current cooperative communication schemes, to achieve cooperative diversity, synchronization between t erminals is usually assumed, which may not be practical since each terminal has its own local oscillator. In this paper, we firstpresent a necessary and sufficient condition for the space-time trel lis codes based on the stack construction proposed by Hammons an d El Gamal to possess the full cooperative diversity order wit hout the synchronization assumption. The condition is that the binary generator metrices of the trellis codes are shift full rank (SFR) matrices, i.e., have full row rank no matter the shifts of their row vectors, where a row corresponds to a terminal (or transmit antenna) and the length of a row vector is the memory size of the corresponding trellis code on the corresponding terminal. We then present a simple construction of SFR for any number of rows, whose number of columns, however, grows exponentiall y with the number of rows. We finally present some systematic SFR matrix constructions including shortest, i.e., square , SFR matrices.
A Framework for GPU 3D Model Reconstruction Using Structure-from-Motion

Title of Thesis: A Framework for GPU 3D Model Reconstruction Using Structure-from-Motion Yu Wang, Master of Science, 2011 Thesis directed by: Marc Olano, Associate Professor Department of Computer Science and Electrical Engineering A framework for three-dimensional (3D) model reconstruction is described in this thesis. The primary application is scanning forest canopies and assisting scientific applications such as fire hazard evaluation and vegetation biomass estimation, using photos taken from a radio-controlled helicopter, although the methods apply to any series of photographs taken along a path. The approach is based on the fact that the photos are taken in a continuous path, thus taking advantage of the adjacency between images. The major contributions of this project are 1) introduce a linear time complexity algorithm that reduces number of image pairs to match for datasets obtained in a continuous path 2) present an optimized high performance framework for GPU 3D reconstruction using structure-from-motion.

Indications of Selenium Protection against Cadmium and Lead Toxicity in Oilseed Rape (Brassica napus L.)

The present study investigated the beneficial role of selenium (Se) in protecting oilseed rape (Brassica napus L.) plants from cadmium (Cd+2) and lead (Pb+2) toxicity. Exogenous Se markedly reduced Cd and Pb concentration in both roots and shoots. Supplementation of the medium with Se (5, 10, and 15 mg kg-1) alleviated the negative effect of Cd and Pb on growth and led to a decrease in oxidative damages caused by Cd and Pb. Furthermore, Se-enhanced superoxide free radicals (O2•¯), hydrogen peroxide (H2O2), and lipid peroxidation, as indicated by malondialdehyde accumulation, but decreased superoxide dismutase and glutathione peroxidase activities. Meanwhile, the presence of Cd and Pb in the medium affected Se speciation in shoots. The results suggest that Se could alleviate Cd and Pb toxicity by preventing oxidative stress in oilseed rape plant.
Time-frequency decomposition for analysis and retrieval of 1-D signals

The time-frequency decomposition of wavelets is used to characterize 1D signals: the goal is to associate to each discrete signal a set of descriptors for fast retrieval in large database and/or recognition in noisy environment. Experiments are shown for an heterogeneous set of one dimensional signals, both synthetic and natural (audio signals). The efficacy of the method is tested against corruption by (white and colored) noise and/or attenuation, in order to simulate the transmission on noisy channels and LANs. Also the extension of the algorithm to 2D signals shows satisfactory results and it has been applied in a content based retrieval engine for image databases.
Reliable Relay Node Placement in Large Scale Dense and Non-uniform Wireless Sensor Network

A Wireless sensor network(WSN) is composed of a large number of sensor nodes, which are densely deployed either inside the phenomenon or very close to it. Unlike traditional networks, a WSN has its own design and resource constraints. As sensor nodes operate on limited battery power, energy usage is a very important concern in a WSN; and there has been significant research focus that revolves around harvesting and minimizing energy. In the proposed work , assuming the WSN to be large scale and non uniform an algorithm is proposed which includes- selection of cluster head from dominating set node,creation of clusters with one and only one cluster head and Relay node deployment in clusters and between cluster heads. In this algorithm, approach of clustering and relay node placement are combined for efficient utilization of energy, thus maximizing network lifetime.
Lase: Locating and applying systematic edits by learning from examples

Adding features and fixing bugs often require systematic edits that make similar, but not identical, changes to many code locations. Finding all the relevant locations and making the correct edits is a tedious and error-prone process for developers. This paper addresses both problems using edit scripts learned from multiple examples. We design and implement a tool called LASE that (1) creates a context-aware edit script from two or more examples, and uses the script to (2) automatically identify edit locations and to (3) transform the code. We evaluate LASE on an oracle test suite of systematic edits from Eclipse JDT and SWT. LASE finds edit locations with 99% precision and 89% recall, and transforms them with 91% accuracy. We also evaluate LASE on 37 example systematic edits from other open source programs and find LASE is accurate and effective. Furthermore, we confirmed with developers that LASE found edit locations which they missed. Our novel algorithm that learns from multiple examples is critical to achieving high precision and recall; edit scripts created from only one example produce too many false positives, false negatives, or both. Our results indicate that LASE should help developers in automating systematic editing. Whereas most prior work either suggests edit locations or performs simple edits, LASE is the first to do both for nontrivial program edits.
Relative leader-member exchange and employee voice Mediating role of affective commitment and moderating role of Chinese traditionality

Purpose – This study aims to examine the effect of relative leader-member exchange (RLMX) on employee voice by developing a moderated mediation model. The model focuses on the mediating role of affective commitment underpinning the relationship between RLMX and employee voice, and the moderating role of Chinese traditionality in influencing the mediation. Design/methodology/approach – We tested the model with data from 358 supervisor-subordinate dyads in a large Chinese company. Employees and their immediate supervisors provided data on separate questionnaires and on different occasions. And then, we used an identification number to match each employee questionnaire with the response of his/her immediate supervisor. Findings – Results indicated that affective commitment fully mediated the positive relationship between RLMX and employee voice, even after controlling for personal leader-member exchange (LMX) quality. We also found that Chinese traditionality moderated the mediated relationship between RLMX .
Energy Requirements of Pregnancy

The energy requirements of pregnancy is a topic of considerable uncertainty because the apparent energy costs—to supply the energy required for the changes in maternal and fetal tissues and to cover the increase in basal metabolic rate (BMR), amounting to the equivalent of an extra 250–300 kcal/day—are rarely paralleled by actual findings. However, few studies have investigated this problem in a controlled longitudinal and statistically acceptable fashion. In this study, measurements of energy intake, BMR, body weight and fatness, physical activity, and mechanical efficiency of movement were made on 162 women in Scotland at 2- to 4-wk intervals throughout pregnancy, and data from 98 of these women were also obtained in the prepregnant state. Data from a parallel study in the Netherlands are also given. The gains in body weight, fatness, the fetal and placental weights, and the increase in BMR were all at the normal expected values. However, increases in energy intake were on the order of only 100 kcal/day during the second and third trimesters. Comparatively small reductions in physical activity, which would be difficult to measure precisely, are described that could account for the difference between actual energy intake and the energy costs of pregnancy.

Social Learning and Voluntary Cooperation Among Like-Minded People

Many people contribute to public goods but stop doing so once they experience free riding. We test the hypothesis that groups whose members know that they are composed only of "like minded" cooperators are able to maintain a higher cooperation level than the most cooperative, randomly composed groups. Our experiments confirm this hypothesis. We also predict that groups of "like-minded" free riders do not cooperate. Yet, we find a high level of strategic cooperation that eventually collapses. Our results underscore the importance of group composition and social learning by heterogeneously motivated agents to understand the dynamics of cooperation and free riding.

Identifying the targets of aminoacyl-tRNA synthetase inhibitors by primer extension inhibition

Aminoacyl-transfer RNA (tRNA) synthetases (RS) are essential components of the cellular translation machinery and can be exploited for antibiotic discovery. Because cells have many different RS, usually one for each amino acid, identification of the specific enzyme targeted by a new natural or synthetic inhibitor can be cumbersome. We describe the use of the primer extension technique in conjunction with specifically designed synthetic genes to identify the RS targeted by an inhibitor. Suppression of a synthetase activity reduces the amount of the cognate aminoacyl-tRNA in a cell-free translation system resulting in arrest of translation when the corresponding codon enters the decoding center of the ribosome. The utility of the technique is demonstrated by identifying a switch in target specificity of some synthetic inhibitors of threonyl-tRNA synthetase.
A review of change point detection methods

In this work, methods to detect one or several change points in multivariate time series are reviewed. They include retrospective (off-line) procedure such as maximum likelihood estimation, regression, kernel methods, etc. In this large area of research, applications are numerous and diverse; many different models and operational constraints (on precision, complexity,.) exist. A formal framework for change point detection is introduced to give sens to this significant body of work. Precisely, all methods are described as a collection of three elements: a cost function, a search method and a constraint on the number of changes to detect. For a given method, we detail the assumed signal model, the associated algorithm, theoretical guarantees (if any) and the application domain. This approach is intended to facilitate prototyping of change point detection methods: for a given segmentation task, one can appropriately choose among the described elements to design an algorithm.
