Chitinophaga polysaccharea sp. nov., an exopolysaccharide-producing bacterium isolated from the rhizoplane of Dioscorea japonica.

A novel strain designated MRP-15(T), belonging to the class Sphingobacteriia (phylum Bacteroidetes), was isolated from the rhizoplane of Dioscorea japonica in South Korea and was characterized taxonomically using a polyphasic approach. The strain was found to comprise Gram-stain-negative, aerobic, non-motile, non-spore-forming rods. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Chitinophaga but was clearly separated from established species of the genus Chitinophaga. 16S rRNA gene sequence similarities between strain MRP-15(T) and type strains of established species of the genus Chitinophaga ranged from 90.3 to 97.8 %. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; major fatty acids, iso-C15 : 0 and C16 : 1ω5c) supported the affiliation of strain MRP-15(T) with the genus Chitinophaga. Therefore strain MRP-15(T) represents a novel species of the genus Chitinophaga, for which the name Chitinophaga polysaccharea sp. nov. is proposed. The type strain is MRP-15(T) ( = KACC 17184(T) = NCAIMB 02530(T)).
Rabphilin‐3A is transported with fast anterograde axonal transport and associated with synaptic vesicles

Rab3a has been proposed to be involved in the process of exocytosis. It undergoes a membrane association/dissociation cycle which is dependent upon alteration in its GTP‐GDP state. Rabphilin‐3A is one of the most attractive candidates for a Rab3a effector molecule in synaptic vesicle exocytosis. It binds selectively to the GTP‐bound form of Rab3a as well as of Rab3c. Fast axonal transport was studied by crushing spinal roots and sciatic nerves, resulting in accumulations of transported, organelle‐bound substances. Rabphilin‐3A was transported with fast anterograde transport, but <10% of the proximal accumulation was detected in the recycling vesicle population. The pattern for accumulation of rabphilin‐3A was similar to that of Rab3a accumulation, including the poor recycling. However, synaptophysin and SV2, two transmembrane synaptic vesicle proteins, accumulated in large amounts in many axons distal to the crushes, and the amounts of recycling synaptophysin and SV2, in percentages of anterograde accumulations, were about 70% and 60%, respectively. Double‐labelling showed a high degree of colocalization between Rab3a and rabphilin‐3A in spinal roots and sciatic nerves. The two proteins essentially colocalized in the nerve terminals of the spinal cord and in motor endplates. Immuno‐EM studies demonstrated that rabphilin‐3A was present on clear small synaptic vesicles in the proximal segment, but was absent from vesicles in the distal segment. Rabphilin‐3A also associated with the synaptic vesicles in the presynaptic compartment. Results indicate that rabphilin‐3A is associated with the membrane of synaptic vesicles during anterograde transport. Furthermore, as it colocalized in most, but not all, structures with Rab3a, results support the hypothesis that rabphilin‐3A is interacting with Rab3a. © 1996 Wiley‐Liss, Inc.
Dynamic Buffer Size Allocation in Wireless Mesh Networks for Non-Elastic Traffic

Resumen: Parametros fundamentales del desempeno de las redes de comunicaciones tales como la probabilidad de perdida de paquetes, el retardo de extremo a extremo, la utilizacion de los canales de transmision, etc., se ven altamente influenciados por el tamano de los buffers de los equipos de red. Estos parametros afectan directamente la calidad del servicio percibida por los usuarios finales. Un dimensionamiento dinamico del tamano de los buffers, a mas de favorecer una asignacion optima de memoria, ayuda a prevenir retardos exagerados y otros problemas asociados a buffers excesivamente grandes. Sin embargo, determinar dinamicamente el tamano de buffer adecuado que cumpla con algun requisito especifico de calidad de servicio, como la probabilidad de perdida, requiere el conocimiento exacto de ciertas funciones de distribucion de probabilidad que en la practica rara vez se encuentran disponibles. Una posible alternativa a este problema consiste en hacer que los dispositivos de red midan ciertos parametros disponibles y a partir de ellos inferir la informacion restante mediante la aplicacion del principio de maxima entropia. Por otra parte, los dispositivos inalambricos imponen restricciones adicionales debido al uso de canales compartidos y mas aun el efecto multi-salto en redes inalambricas de malla sin infraestructura. Este articulo se centra en la implementacion y evaluacion de un mecanismo de dimensionamiento dinamico de buffers basado en maxima entropia en redes inalambricas de malla. Los resultados obtenidos verifican el correcto funcionamiento y la mejora de prestaciones en diversos escenarios. Abstract: Fundamental network performance parameters as the packet loss probability, end-to-end delay, utilization of transmission channels, etc., are highly influenced by the buffer size of network devices. These parameters directly affect the quality of service perceived by end users. A dynamic buffer sizing can provide optimal memory allocation, and also helps to prevent exaggerated delays and other problems associated with excessively large buffers. Nevertheless, a dynamic determination of the proper buffer size that meets any specific quality of service requirement, as the packet loss probability, needs the exact knowledge of certain probability distribution functions which in practice are rarely available. A possible alternative to this problem is that network devices measure some available parameters and from them infer the remaining information by applying the maximum entropy principle. On the other hand, wireless devices impose additional restrictions due to the use of shared channels and even more to the multi-hop effect in infrastructure-less wireless mesh networks. This article focuses on the implementation and evaluation of a dynamic buffer sizing mechanism based on maximum entropy when it is applied in wireless mesh networks. Simulation results verify the proper operation and improved performance in different mesh scenarios.
Automatic Color-to-Gray Conversion for Digital Images in Gradient Domain

Color-to-grayscale conversion for digital color images is widely used in many applications. In this paper an automatic gradient domain color-to-gray conversion method is described. By enhancing the luminance gradient with a modulated chromatic difference enhancement in CIELAB space, a gradient field is created to construct the resulting grayscale image using a Poisson equation solver. A sign function for the gradient is defined for isoluminance color images to keep correct color ordering. By introducing a structural similarity index measurement (SSIM), the main parameters of the method are automatically optimized in the sense of human vision. Therefore, this method can automatically produce artifact-free and salience-preserving grayscale images that coincide with human perception for the color difference.
Stochastic Inequality Probabilities for Adaptively Randomized Clinical Trials

We examine stochastic inequality probabilities of the form P (X > Y ) and P (X > max (Y, Z )) where X, Y, and Z are random variables with beta, gamma, or inverse gamma distributions. We discuss the applications of such inequality probabilities to adaptively randomized clinical trials as well as methods for calculating their values. (© 2006 WILEY‐VCH Verlag GmbH & Co.

Multi-modal output composition for human-computer dialogues

The authors discuss the development of a prototype multimodal human-computer interface system, called CUBRICON, which is a research platform for investigating how knowledge-based approaches can best be applied to enhance human-computer interfaces. Four critical features of such an interface are introduced along with CUBRICON's initial approach to achieving them. Several knowledge sources have been defined within CUBRICON. These serve as the basis for CUBRICON's multimedia output planning process. These knowledge sources include: characteristics of the information, a model of the ongoing discourse, a user/task model, and a knowledge base of task domain and related interface information. CUBRICON's output planning process includes selection of appropriate media/modalities, selection of ancillary relevant information, determination of whether display resources are available, modification of resources or information to be expressed (if necessary), modification of selected output media/modalities (if necessary), and composition of the output. Examples are given for the application task domain of military tactical air control. <<ETX>>
Networked‐based stabilization via discontinuous Lyapunov functionals

This paper presents a new stability and L2‐gain analysis of linear Networked Control Systems (NCS). The new method is inspired by discontinuous Lyapunov functions that were introduced by Naghshtabrizitextitet al. (Syst. Control Lett. 2008; 57:378–385; Proceedings 26th American Control Conference, New York, U.S.A., July 2007) in the framework of impulsive system representation. Most of the existing works on the stability of NCS (in the framework of time delay approach) are reduced to some Lyapunov‐based analysis of systems with uncertain and bounded time‐varying delays. This analysis via time‐independent Lyapunov functionals does not take advantage of the sawtooth evolution of the delays induced by sample‐and‐hold. The latter drawback was removed by Fridman (Automatica 2010; 46:421–427), where time‐dependent Lyapunov functionals for sampled‐data systems were introduced. This led to essentially less conservative results. The objective of the present paper is to extend the time‐dependent Lyapunov functional approach to NCS, where variable sampling intervals, data packet dropouts, and variable network‐induced delays are taken into account. The Lyapunov functionals in this paper depend on time and on the upper bound of the network‐induced delay, and these functionals do not grow along the input update times. The new analysis is applied to the state‐feedback and to a novel network‐based static output‐feedback H∞ control problems. Numerical examples show that the novel discontinuous terms in Lyapunov functionals essentially improve the results. Copyright © 2011 John Wiley & Sons, Ltd.
Pulse delay control strategy for improved power control and efficiency in multiple resonant load systems

Nowadays, induction heating cookers are becoming more popular due to their high performance and efficiency. Among the different alternatives available, the total-active-surface concept is leading the technology development. This technology is based on a set of inductors placed in a matrix-like distribution. The main benefit of this technology is the possibility of using as many pots are needed, with any shape, and in any position in the whole appliance surface. In order to obtain an efficient and high-power-density implementation new multiple-output power converters are required. The aim of this paper is to propose a new control strategy for the series resonant multi-inverter topology in order to obtain accurate power control in each inductor while keeping a high efficiency. To achieve this aim, the Pulse Delay Control is proposed. The main analytical and simulation results are presented, and the proposal is validated through a multi-load prototype.
A Mixed Method Approach to Understanding Crowdsourcees' Engagement Behavior

With an increasing amount of arising crowdsourcing initiatives, insights are needed on how to successfully drive initial and sustained platform-activity, as a form of value co-creation between crowdsourcer and crowdsourcees. Therefore, the engagement concept, known as a micro-foundation of value co-creation, serves to holistically understand crowdsourcees’ psychological and behavioral responses along the IT-mediated crowdsourcing journey. Due to the multidimensionality of the concept, a mixed method approach is proposed for exploring qualitatively and quantitatively stimuli’s effect on psychological states and engagement behaviors. Therefore, two measuring approaches, the Sequential Incident Laddering Technique and a Panel Poisson Model, are presented. Preliminary findings suggest that, next to other factors, crowdsourcer-interaction and high-effort tasks serve as dominant drivers, fostering psychological engagement beyond the interaction process, while crowd-interaction rather drives within-process engagement behavior. This research in progress provides IS-researchers and practitioners initial insights into IT-enabled value co-creation processes.
Superradiance in a Two-Dimensional Photonic Bandgap Structure

In this paper, we study the superradiant decay of an ensemble of inverted two-level atoms embedded into a continuous dielectric and a two-dimensional (2-D) photonic crystal with lateral confinement of the radiation. The nonlinear superradiance pulse characteristics are calculated using a Green's-function-based model. Specifically, we predict fast phase synchronization across the ensemble that builds up a distributed feedback structure responsible for the superradiation anisotropic emission and the directional switching. We show that the transfer of the optical excitation takes place along the Bragg planes and is manifested by strong energy localization
Monitoring of taints related to printed solid boards with an electronic nose

The main objectives were to combine knowledge gathered from the electronic nose (EN) with traditional analytical reference methods for measuring volatile compounds, such as sensory and headspace methods. The impacts of different colouring agents on the sensory properties of packaging materials when analysed by EN were determined. The first step in investigations using the EN was optimization of sample treatment and analysis parameters for the samples. The best resolution was achieved at 60 ° C in 20min, and the effect of humidity on the EN sensors was confirmed. A comparison was made of three sensory methods for analysing taints of packaging materials. The study showed that the odour of the packaging itself was often not a reliable indication of the taint perceived in the packed foodstuff and should be regarded only as indicative. Taints caused by pigments of printed solid boards were analysed by EN. Twenty samples were studied, representing unprinted solid board, lacquered solid board, offset printed solid board with 14 different colours and offset printed, lacquered solid board with four colours. The EN succeeded in grouping these materials according to their colouring agents or lacquering, despite slight overlapping of replicates, and the results appeared to reflect at least to some extent the off-flavours perceived in sensory evaluation. The results of this study are only indicative, because the analysis of results from different sources or equipment requires more extensive use of statistical methods.
Functional Magnetic Resonance Adaptation in Visual Neuroscience

Functional magnetic resonance imaging (fMRI) is a powerful non-invasive tool to investigate neuronal processing. In the last ten years a new methodological approach in the field of fMRI has been developed: fMRI adaptation. It has been found that the repetition of a stimulus leads to a decrease of the fMRI signal in the brain region that processes this stimulus. The phenomenon has been related to neuronal adaptation effects found in single-cell recordings. Since the first experiments that observed fMRI-adaptation effects, the method has been applied extensively to study various visual phenomena, such as the perception of motion, shape, objects, and orientation. The great advantage of fMRI adaptation is that it allows assessing the functional response profile of a brain region at a subvoxel level. The purpose of the current review is to evaluate the different experimental approaches used to elicit fMRI-adaptation effects. We discuss papers published in the domain of visual neuroscience that made use of fMRI-adaptation paradigms. In doing so, we focus on methodological considerations concerning experimental design, stimulus presentation and influencing factors such as awareness and attention. In the course of this review, we show that different fMRI-adaptation designs capture heterogeneous neuronal adaptation effects. As the picture of the mechanisms underlying neuronal adaptation changes from simple synaptic fatigue to complex network interactions, the concept of fMRI adaptation has to be redefined.
Ketorolac and Enoxaparin Affect Arterial Thrombosis and Bleeding in the Rabbit

Background Nonsteroidal anti‐inflammatory drugs (NSAIDs) may interfere with hemostasis during the perioperative period, and the combination of NSAID and enoxaparin could increase this effect. The aim of this prospective, blinded experimental study was to assess these effects using a model of arterial thrombosis and bleeding in the rabbit. Methods After anesthesia was induced and monitors placed, the common carotid arteries were exposed, and 60% stenosis of the right common carotid artery was produced. Twenty minutes later, a compression injury of the artery was produced that triggered a series of cyclic episodes of thrombosis and clot lysis. This was manifested as cyclic flow reductions (CFR; measured with an electromagnetic flow meter). After the first flow reduction was noted, the rabbits were immediately and randomly assigned to one of four groups (n = 10 each) that received intravenous infusions: control, ketorolac (2 mg/kg), enoxaparin (0.5 mg/kg), and ketorolac plus enoxaparin (2 mg/kg and 0.5 mg/kg, respectively). The number of CFRs that occurred in the subsequent 20‐min period was used as a measure of treatment effect. The contralateral common carotid artery was exposed, and both stenosis and injury were produced. The ability of the administered drug to prevent thrombosis was assessed as the number of CFRs that occurred during the first 20‐min period after vessel injury. In addition, both before and after group assignment and drug injection, bleeding times were noted and a platelet aggregation test was performed. Laparotomy was followed by a spleen section, and the extent of the wound and the amount of splenic bleeding were measured. Results The treatment effect was indicated by the median number of CFRs, which was 5.5 in the control group, 1 in the ketorolac group, 2 in the enoxaparin group, and 0 in the ketorolac + enoxaparin group. The prevention effect was indicated by the median number of CFRs, which was 4 in the control group, 0 in the ketorolac group, 2 in the enoxaparin group, and 0.5 in the ketorolac + enoxaparin group. Bleeding time was significantly lengthened in the enoxaparin and in the ketorolac + enoxaparin groups. Splenic and wound bleeding was greater in the ketorolac group. Platelet aggregation was completely inhibited in the ketorolac and the ketorolac + enoxaparin groups. Conclusions Ketorolac had an important antithrombotic activity. The association of enoxaparin with ketorolac seemed to lengthen the bleeding time observed with ketorolac.
Vehicle velocities estimation based on mixed EKF

Longitudinal and lateral vehicle velocities are the important information for active vehicle stability control. But for both technical and economical reasons, these vehicle states can not be measured directly in a standard car. In order to provide high precision vehicle velocities information for active stability control system, a mixed EKF is presented to estimate the longitudinal and lateral vehicle velocities, which is suitable for continuous state variables with discrete observation. To offer the necessary tyre-road forces information for estimating vehicle velocities, a random walk model is proposed to model the tyre-road forces. It could avoid the complex tyre-road force model effectively. In order to evaluate the performance of the proposed mixed EKF, the simulation are carried out in the ISO double lane change condition and slalom condition with the parameters of Hongqi vehicle CA7180A3E. Meanwhile, estimation results are compared with the vehicle dynamics software veDYNA. Simulation results show that the introduced mixed EKF method has perfectly high precision and could satisfy the requirement of active vehicle stability control system.
Citrate-condensing enzyme-oxalacetate binary complex. Studies on its physical and chemical properties.

Abstract A binary complex is formed between citrate-condensing enzyme and oxalacetate. Complex formation is accompanied by a change in protein conformation, as judged by changes in ultraviolet absorption, a small change in optical rotatory dispersion, and increased stability to denaturation. The stability of the complex in urea has made it possible to estimate that there is 1 oxalacetate molecule per active site on the enzyme, and that the dissociation constant of this complex is about 6 x 10-7 m. Urea treatment of the enzyme results in the exposure of sulfhydryl groups, changes in the ultraviolet absorption, changes in the optical rotatary dispersion spectrum indicative of unfolding, and changes in the sedimentation behavior. Urea treatment of the complex, however, shows essentially none of these changes. A number of analogues were tested as to their ability to bind to the oxalacetate site. On the basis of these studies it was concluded that oxalacetate was bound through both carboxyl groups, as well as through the carbonyl oxygen. It seems that once the oxalacetate site on the enzyme is occupied, then urea (or other denaturants) cannot react with the enzyme.
The advanced cancer patient experience of undertaking meaning and purpose (MaP) therapy

Abstract Objective: The objective of this study was to describe the experience of undertaking meaning and purpose (MaP) therapy for patients with advanced cancer, with an aim of refining therapeutic processes involved prior to pilot testing. Specifically, we were interested in examining the themes arising from participation in the intervention in relation to our therapeutic goals, and how acceptable both the number of sessions and processes used were. Method: A convenience sample of people living with advanced cancer was recruited to participate in this process, resulting in 24 therapy sessions for analysis. Results: A thematic analysis of each session illustrated that the process of MaP therapy is one that encourages reflection, offers insights, and can be confrontational, but can also allow participants to “shift” their perspective and focus onto meaningful goals. Results illustrate how the therapist creates a therapeutic frame that holds up a poignant portrayal of the meaning of life lived, and mirrors this to the patient, such that they grasp its rich texture. Participants' descriptions showed how they were buoyed forward as a result, with renewed vigor and enthusiasm, despite their illness and any physical restrictions that it imposed. Significance of results: A planned pilot test of this intervention will enable us to determine potential effect sizes of this therapy in reducing distress and increasing meaning prior to a full randomized controlled trial. Understanding the processes involved and the experiences of participation in meaning-based therapies is crucial to the future strength of this area of psychotherapy.
