An update on post-translational modifications of hydroxyproline-rich glycoproteins: toward a model highlighting their contribution to plant cell wall architecture

Plant cell walls are composite structures mainly composed of polysaccharides, also containing a large set of proteins involved in diverse functions such as growth, environmental sensing, signaling, and defense. Research on cell wall proteins (CWPs) is a challenging field since present knowledge of their role into the structure and function of cell walls is very incomplete. Among CWPs, hydroxyproline (Hyp)-rich O-glycoproteins (HRGPs) were classified into three categories: (i) moderately glycosylated extensins (EXTs) able to form covalent scaffolds; (ii) hyperglycosylated arabinogalactan proteins (AGPs); and (iii) Hyp/proline (Pro)-Rich proteins (H/PRPs) that may be non-, weakly- or highly-glycosylated. In this review, we provide a description of the main features of their post-translational modifications (PTMs), biosynthesis, structure, and function. We propose a new model integrating HRGPs and their partners in cell walls. Altogether, they could form a continuous glyco-network with non-cellulosic polysaccharides via covalent bonds or non-covalent interactions, thus strongly contributing to cell wall architecture.
Low source current-ripple high gain boost converter

This paper presents analysis and design of low source current ripple high-gain boost converter. The proposed converter exhibits higher voltage gain, almost double, in comparison to the well-established conventional boost converter. A steady-state analysis is made, and then converter elements design expressions are established. These design expressions are then used to design a 24 to 100 V, 50 W prototype. Steady-state performance proposed converter is compared with other high-gain dc-dc converters. Simulation and experimental results are presented to validate the proposed design. Experimental measurements are in close correlation to simulation results.
Towards a meaningful formal definition of real-time computations

There are few formal de nitions of real{time problems, and the currently available de nitions do not capture all the relevant aspects of such computations. We propose a new de nition, and we believe that it allows a uni ed treatment of all practically meaningful variants of real{time computations. In order to support our thesis, we also present some important features of real{time algorithms, namely the presence of deadlines and the continuous arrival of input data, together with their corresponding models in our formalism. We believe that this is a rst step towards a uni ed and realistic complexity theory for real{time computation.
A human-robot interaction interface for mobile and stationary robots based on real-time 3D human body and hand-finger pose estimation

This paper presents a real-time gesture-based human-robot interaction (HRI) interface for mobile and stationary robots. A human detection approach is used to estimate the entire 3D point cloud of a human being inside the field of view of a moving camera. Afterwards, the pose of the human body is estimated using an efficient self-organizing map approach. Furthermore, a hand-finger pose estimation approach based on a self-scaling kinematic hand skeleton is presented and evaluated. A trained support vector machine is used to classify 29 hand-finger gestures based on the angles of the finger joints. The HRI interface is integrated into the ROS framework and qualitatively evaluated in a first test scenario on a mobile robot equipped with an RGB-D camera for gesture interaction. Since the hand-finger pose, the hand-finger gesture, as well as the whole body pose are estimated, the interface allows a flexible implementation of various applications.
3D paint

This paper advances a means by which the conventions and methods of digital "painting" and image manipulation programs can be extended into the third dimension, providing sculpting tools that are natural and appropriate for a restricted but very useful class of models. Attempts to approximate "drawing" in 3D do not necessarily involve computer graphics [Gregory71]. Efforts in this area are a subject of continuing graphics research [Schmandt82], [Sachs89]. The key to the approach undertaken in the work described here is the use of an unusual hardware technique for displaying video rasters as surfaces. With such a display, existing software for 2D graphics and image processing can be used, without modification, for creating and modifying three-dimensional surfaces. The resulting raster data can then be converted into conventional 3D databases for further processing and display. The aim of this research is to create consistent, unified methods for computer-assisted drawing, painting, modeling, and animation.
Estimation of confidence intervals for Multinomial proportions of sparse contingency tables using Bayesian methods

Multinomial distribution, widely used in applications with discrete data, witnessed varieties of competing intervals from frequentist to Bayesian methods, still prove to be interesting in the case of zero counts or sparse contingency tables. The methods commonly recommended in both approaches are considered based on its influence of zero counts, polarizing cell counts, and aberrations. The inference based on comparative study shows that Bayesian approach, with an appropriate prior could be a good choice in dealing with a sparse data set without any imputation for zero values.
A hybrid agent based virtual organization for studying knowledge evolution in social systems

Social modeling applies computational methods and techniques to the analysis of social processes and human behavior.Cultural algorithms (CA’s) are evolutionary systems which utilize agent technology and which supports any evolutionarystrategy like genetic algorithm, evolutionary algorithm or swarm intelligence or ant algorithms. CA’s have been used formodeling the evolution of complex social systems, for re-engineering rule based systems, for data mining, and for solvingoptimization problems. In the current study a cultural algorithm framework is used to model an Agent Based VirtualOrganization (ABVO) for studying the dynamics of a social system at micro as well as macro level. Research gap exists indefining a concrete and systematic method for evaluating and validating Agent Based Social Systems (ABSS). Also theknowledge evolution process at micro and macro levels of an organization needs further exploration. The proposed CA isapplied to the problem of multi-objective optimization (MOO) of classification rules. The evolutionary knowledgeproduced by the agents in creating the rules is accepted into the belief space of the CA and macro evolution takes place.The belief space in turn influences the agents in successive generations. The rules created by the individuals and theknowledge sources created during evolution provide a concrete method to evaluate both the individuals as well as thewhole social system. The feasibility of the system has been tested on bench mark data sets and the results are encouraging.
Un Modèle De Collaboration Pour La Diffusion De Contenus Basé Sur L’utilisation De La Blockchain

Contexte Le marche de la video a la demande est en pleine mutation. La place occupee historiquement par les fournisseurs d'acces (FAI) est de plus en plus fragilisee par la montee en puissance des fournisseurs de contenus en streaming (FC) utilisant les reseaux tiers (CDN) pour ameliorer la qualite de diffusion. Cette mutation entraine des effets pervers. D'une part il est impossible de garantir une qualite de service sans collaboration entre les FAI, les CDN et les fournisseurs de contenus. D'autre part les entreprises controlant a la fois le contenu et la diffusion se concentrent verticalement, ce qui est nefaste pour la perenite du reseau (manque d'investissement, oligopoles)[2]. Nos recherches precedentes [5] portent sur la definition d'un modele de collaboration en vue de reduire les couts de diffusion et d'assurer une qualite de service. Nos nouveaux axes de recherche [4] portent sur l'utilisation de facilitateurs techniques comme la blockchain et les smart contracts pour parvenir a implementer cette collaboration sous forme de contrats de diffusion de contenus. A l'image du mouvement democratie by design [3] qui nourrit la reflexion sur les structures du cyberespace, il est possible de voir dans ces technologies une garantie du maintien d'une libre concurrence [6].
The Design and Implement of Time Synchronization Between Base Station and Sensor Node in Wireless Sensor Networks

Time synchronization may play a key role in wireless sensor networks to meet real-time and energy-saving requirements and improve data-fusion and multiplexing efficiency. In this paper, we introduce a clock synchronization algorithm between the base station and sensor node used in wireless check meter system. The algorithm can not only been extended more conveniently, but also less affected by environment. The algorithm is implemented in the platform of s3c2410 solidified OS of Windows CE.Net. So the most important interrupt delay contributor, ISR and IST, can not be ignored, A result for the maximum clock skew of the hardware-based synchronization is presented, which can fulfill the need of wireless sensor networks built for wireless check meter system.
Metrics for performance evaluation of elliptic extended object tracking methods

The objective of extended object tracking is to simultaneously track a target object and estimate its shape. As a consequence, it becomes necessary to incorporate both location and shape errors in the performance assessment of extended object tracking methods. In this work, we highlight the difficulties of selecting a proper metric for this purpose and discuss currently used metrics from literature. Furthermore, we suggest the Gaussian Wasserstein metric for comparing elliptic shapes and illustrate its advantages.
A Web-Based Application Development Course for the Computing Curricula 2001/NC3 Track

With the growing use of Web technologies in various critical applications, it is important for a Computer Science student, whether undergraduate or graduate, to gain experience in developing multi-tier Web-based applications. These applications provide access to data and service from a remote server, which may in turn access databases distributed across the enterprise network or the Internet. The fact that the Web is becoming the next-generation computing platform makes the introduction of Web-based application development into the Computer Science curriculum an important task. In the new Computing Curricula 2001 report [6], net-centric computing is one of the components in the Computer Science Body of Knowledge, as recommended by the joint ACM/IEEE Task Force on Computing Curricula. In this paper, we first analyze the current practice of teaching Webbased Development, including our own experience, and then propose an integrated design of a Web-based Development course to be adopted as an NC3 course (Building Web Applications ) as categorized in Computing Curricula 2001.
Tidal Interaction in High Mass X-ray Binaries and Symbiotic Stars

This paper summarizes our recent results on tidal interaction in high mass X-ray binaries and symbiotic stars. We demonstrate that the giant in symbiotic stars with orbital periods <1200 d are co-rotating (synchronized). The symbiotics MWC 560 and CD-4314304 probably have high orbital eccentricity. The giants in symbiotic binaries rotate faster than the field giants, likely their rotation is accelerated by the tidal force of the white dwarf. The giant/supergiant High mass X-ray binaries with orbital periods <40 d are synchronized. However the Be/X-ray binaries are not synchronized. In the Be/X-ray binaries the circumstellar disks are denser and smaller than those in isolated Be stars, probably truncated by the orbiting neutron star.
The Effects of Communicative Language Teaching of Student-Centered Approach on Students’ Speaking Ability at XI Grade of SMAN 1 Lubuk Sikaping

This study aimed to find out the effects of communicative language teaching on students’ speaking skill using video. The participants of this study involved 60 students class XI of SMAN I Lubuk Sikaping in the academic year of 2017/2018. The participants of this study were divided into two classes (experimental and control class): class XI IPA 2 as the control group and class XI IPA 1 as the experimental group. This study used quantitative method and the data analyzed by using statistical analysis. The data obtained from the result of pre-test and post-test that was given to the participants during the process of the research. The result of this study was found that the mean of control pre-test class was 63.68 and post-test of control class was 80.0, while the mean of experimental pre-test was 64.28 and post-test of experimental class was 85.69. However, the mean value on the speaking skill test of the experimental group is higher than that of the control group. The increase of the scores in experimental class showed that the communicative language teaching was effective to use in teaching speaking in class XI of SMAN Lubuk Sikaping. Moreover, the result of the t-test was 0.011< 0.05, it indicated that there is a significant differences between students’ speaking ability who are taught using communicative language teaching and students’ speaking ability who are taught without using communicative language teaching.
Author ' s personal copy Utilizing RxNorm to support practical computing applications : Capturing medication history in live electronic health records

RxNorm was utilized as the basis for direct-capture of medication history data in a live EHR system deployed in a large, multi-state outpatient behavioral healthcare provider in the United States serving over 75,000 distinct patients each year across 130 clinical locations. This tool incorporated auto-complete search functionality for medications and proper dosage identification assistance. The overarching goal was to understand if and how standardized terminologies like RxNorm can be used to support practical computing applications in live EHR systems. We describe the stages of implementation, approaches used to adapt RxNorm’s data structure for the intended EHR application, and the challenges faced. We evaluate the implementation using a four-factor framework addressing flexibility, speed, data integrity, and medication coverage. RxNorm proved to be functional for the intended application, given appropriate adaptations to address high-speed input/output (I/O) requirements of a live EHR and the flexibility required for data entry in multiple potential clinical scenarios. Future research around search optimization for medication entry, user profiling, and linking RxNorm to drug classification schemes holds great potential for improving the user experience and utility of medication data in EHRs. 2012 Elsevier Inc.

World Alzheimer Report 2009

Cover image This participant in the ARDSI day care centre in Cochin, India, was diagnosed with dementia at age 68 and was initially taken care of at home by family and domestic servants. Her aggressive behaviour became problematic, and she was enrolled in the daycare centre. At the centre she chats, tells stories and benefits from trained staff members and volunteers, such as Geetha, who are understanding and kind. 2009 2 Demographic ageing is a worldwide process that shows the successes of improved healthcare over the last century. Many are now living longer and healthier lives and so the world population has a greater proportion of older people. We all agree that ageing brings some challenges as well. Many international meetings have touched on this issue and adopted statements, for instance the Madrid International Plan of Action on Ageing from 2002. A clearly negative effect of ageing is the significant increase in the number of people with Alzheimer's disease and related dementias. Alzheimer's Disease International (ADI) has commissioned this report in order to support Alzheimer associations around the world in working with their governments on strategies to improve the lives of people with dementia and their carers, and to increase research efforts. To encourage the development of those national strategies, it is very important that the World Health Organization makes dementia a global health priority. If a country is in the business of supporting or spurring medical research, its portfolio ought to include funding Alzheimer's disease research in a proportion that matches its burden to the country. To make clear why this is important and why it is urgent, we wanted to put together updated information on the prevalence and impact of the disease and offer a framework for solutions. Some recent experiences have been very encouraging. In 2004, Australia was the first country to make dementia a national health priority, and national dementia strategies have been launched in France, South Korea, England, Norway and the Netherlands. We also want to highlight a very recent initiative from the European Commission as the first international action plan on dementia. This report gives an overview and analysis of the situation, based on the currently available research data. The 2009 World Alzheimer Report confirms that there are many millions of people living with Alzheimer's or another dementia. This report and all earlier studies indicate that the current number of people living with dementia …
Stabilization of the strongly damping inertia wheel pendulum by a nested saturation functions

The stabilization of the strongly damping inertia wheel pendulum around its unstable equilibrium point is presented in this paper. The fact that this system can be rewritten approximately as a chain of integrators with and nonlinear perturbation suggests the use of a nested saturation based controller for making all state variables converge to zero. The proposed control strategy makes the closed-loop system globally asymptotically and locally exponentially stable around the unstable inverted vertical position, even when the physical damping is presented in the model.
A qualitative analysis of migrant social workers’ work experiences and perceived prejudice from an empowering acculturative integration approach

ABSTRACT An increasing number of migrant social workers are employed in the UK social work sector. This article explores the acculturative integration experiences of a small group of migrant social workers. We critically observe that research on migrant professionals’ trajectories should adopt theories that emphasise people’s empowerment and potential for agency. We use a framework drawing on liberation psychology for analysing the autobiographical narratives of a sample of migrant social workers employed in England. Findings indicate that the participants perceived prejudice on a number of occasions and circumstances. Even though in their narrative of survival they talked about activating several psychosocial resources, they were skeptical about their professional development and dissatisfied at work. The paper discusses the emerging findings while highlighting the framework’s relevance for understanding these experiences from an empowering acculturation perspective and suggesting ways of improving migrant social workers’ acculturative integration by addressing systemic barriers.
Agent-based evolutionary multiobjective optimisation

This work presents a new evolutionary approach to searching for a global solution (in the Pareto sense) to a multiobjective optimisation problem. The novelty of the method proposed consists in the application of an evolutionary multi-agent system (EMAS) instead of classical evolutionary algorithms. Decentralisation of the evolution process in EMAS allows for intensive exploration of the search space, and the introduced mechanism of crowd allows for effective approximation of the whole Pareto frontier. In the paper the technique is described as well as preliminary experimental results are reported.
Design patterns and change proneness: an examination of five evolving systems

Design patterns are recognized, named solutions to common design problems. The use of the most commonly referenced design patterns should promote adaptable and reusable program code. When a system evolves, changes to code involving a design pattern should, in theory, consist of creating new concrete classes that are extensions or subclasses of previously existing classes. Changes should not, in theory, involve direct modifications to the classes in prior versions that play roles in a design patterns. We studied five systems, three proprietary systems and two open source systems, to identify the observable effects of the use of design patterns in early versions on changes that occur as the systems evolve. In four of the five systems, pattern classes are more rather than less change prone. Pattern classes in one of the systems were less change prone. These results held up after normalizing for the effect of class size - larger classes are more change prone in two of the five systems. These results provide insight into how design patterns are actually used, and should help us to learn to develop software designs that are more easily adapted.
Right-handed sector leptogenesis

Instead of creating the observed baryon asymmetry of the universe by the decay of right-handed (RH) neutrinos to left-handed leptons, we propose to generate it dominantly by the decay of the RH neutrinos to RH leptons. This mechanism turns out to be successful in large regions of parameter space. It may work, in particular, at a scale as low as ∼TeV, with no need to invoke quasi-degenerate RH neutrino masses to resonantly enhance the asymmetry. Such a possibility can be probed experimentally by the observation at colliders of a singlet charged Higgs particle and of RH neutrinos. Other mechanisms which may lead to successful leptogenesis from the RH lepton sector interactions are also briefly presented. The incorporation of these scenarios in left–right symmetric and unified models is discussed.
IBuILD: Incremental bag of Binary words for appearance based loop closure detection

In robotics applications such as SLAM (Simultaneous Localization and Mapping), loop closure detection is an integral component required to build a consistent topological or metric map. This paper presents an appearance based loop closure detection mechanism titled `IBuILD' (Incremental bag of BInary words for Appearance based Loop closure Detection). The presented approach focuses on an online, incremental formulation of binary vocabulary generation for loop closure detection. The proposed approach does not require a prior vocabulary learning phase and relies purely on the appearance of the scene for loop closure detection without the need of odometry or GPS estimates. The vocabulary generation process is based on feature tracking between consecutive images to incorporate pose invariance. In addition, this process is coupled with a simple likelihood function to generate the most suitable loop closure candidate and a temporal consistency constraint to filter out inconsistent loop closures. Evaluation on different publicly available outdoor urban and indoor datasets shows that the presented approach is capable of generating higher recall at 100% precision in comparison to the state of the art.
