Using DPM on the Way to Tailored Prismatic Spouted Beds
Authors: Salikov Vitalij , Antonyuk Sergiy , Heinrich Stefan
Published: February 2012

Spouted beds are used for miscellaneous applications such as drying, granulation, coating of solids and for chemical reactions. The discrete particle model (DPM) is a powerful tool supporting developers to create tailor‐made spouted beds for specific process requirements. The limitation of DPM for large‐scale simulations, resulting from high computational effort, can be avoided by simulation of rectangular apparatuses of appropriate thickness, since the fluid and particle dynamics are independent in this direction and scale‐up can simply be achieved by extending of the apparatus thickness. In this contribution DPM was used to investigate the influence of the gas flow rate, the particle friction coefficient and the geometry basis angle on the particle dynamics in the spouted bed.
A replicated information system to enable dynamic collaborations in the Grid
Authors: Torres Erik , Moltó Germán , Segrelles Damià , Blanquer Ignacio , Vicente Hernández
Published: February 2012

The main advantage of Grid computing over other distributed computing paradigms is its capability to coordinate the access to data and resources in a virtual multi‐institutional environment. To this end, the information system plays a decisive role in selecting the services that meet the applications' needs. This paper presents an information system for the Grid that provides transparent and scalable group communication services to standard Grid applications, with the objective of supporting dynamic collaborations that could help address problems that involve only some participants of a virtual organization. In particular, it enables more flexible delivery mechanisms, which allows applications to select the appropriate services before sending their data to the information system. This significantly enhances the protection of data from unauthorized access, and avoids the transmission of unnecessary messages over the network. The proposed information system is based on the use of XML technologies and replication. It introduces several new advanced features that are not currently supported as a whole by any Grid middleware, such as: several entry points to the information, persistent capabilities, support for advanced queries based on XQuery, and support for the industrial standard WS‐Policy. The information system has been stress tested under realistic workloads in a Grid infrastructure with 50 sites. Scalability has been evaluated in up to 1000 messages that can be up to 10KB in size each, updated with a frequency of 5min. Copyright © 2012 John Wiley & Sons, Ltd.
Applying a metadata level for concurrency in wireless sensor networks
Authors: del Cid Pedro Javier , Hughes Danny , Michiels Sam , Joosen Wouter
Published: February 2012

Achieving a clean separation of concerns is a well known approach to improving system adaptability and evolution. We propose to apply this principle to run‐time reconfigurable component models for networked embedded systems. By separating configuration properties from runtime component instances, we achieve: (i) improved support for concurrent component use, (ii) optimized resource use, and (iii) reduced effort in runtime configuration management. We demonstrate how this approach can be seamlessly implemented on existing component models for wireless sensor networks without imposing additional constraints and without changes to their API or coordination model. Furthermore, significant memory savings are achieved in concurrent scenarios. Copyright © 2012 John Wiley & Sons, Ltd.

Published: February 2012

Background

Manualized cognitive–behavioural treatment (CBT) is underutilized in the treatment of bulimic symptoms. Internet‐delivered treatment may reduce current barriers.

Objective

This study aimed to assess the efficacy of a new online CBT of bulimic symptoms.

Method

Participants with bulimic symptoms (n = 105) were randomly allocated to online CBT, bibliotherapy or waiting list/delayed treatment condition. Data were gathered at pre‐treatment, post‐treatment and 1‐year follow‐up.

Outcome Measures

The primary outcome measures were the Eating Disorder Examination Questionnaire (EDE‐Q) and the frequency of binge eating and purging episodes. The secondary outcome measure was the Body Attitude Test.

Results

Dropout from Internet treatment was 26%. Intention‐to‐treat ANCOVAs of post‐test data revealed that the EDE‐Q scores and the frequency of binging and purging reduced more in the online CBT group compared with the bibliotherapy and waiting list groups (pooled between‐group effect size: d = 0.9). At 1‐year follow‐up, improvements in the online CBT group had sustained.

Conclusion

This study identifies online CBT as a viable alternative in the treatment of bulimic symptoms. Copyright © 2012 John Wiley & Sons, Ltd.

Key Practitioner Message

In comparison with no treatment and unsupported bibliotherapy, online CBT induces strong reductions in bulimic symptoms.

Internet‐delivered treatment may provide an acceptable treatment alternative for bulimic patients who are reticent about face‐to‐face contact.

Therapist support appears to be a critical determinant of treatment adherence and effectiveness.

Unsupported bibliotherapy may have only small immediate effects but may increase the probability of recovery in the long term by promoting positive attitudes towards treatment.
Energy‐efficient and localized lossy data aggregation in asynchronous sensor networks
Authors: Zhang J. , Shen X. , Zeng H. , Dai G. , Bo C. , Chen F. , Lv C.
Published: February 2012

In wireless sensor networks, most data aggregation scheduling methods let all nodes aggregate data in every time instance. It is not energy efficient and practical because of link unreliability and data redundancy. This paper proposes a lossy data aggregation (LDA) scheme to reduce traffic and save energy. LDA selects partial child nodes to sample data at partial time slots and allows estimated aggregation at parent nodes or a root in a network. We firstly consider that all nodes sample data synchronously and find that the error between the real value of a physical parameter and that measured by LDA is bounded respectively with and without link unreliability. Detailed analysis is given on error bound when a confidence level is previously assigned to the root by a newly designed algorithm. Thus, each parent can determine the minimum number of child nodes needed to achieve its assigned confidence level. We then analyze a probability to bound the error with a confidence level previously assigned to the root when all nodes sample data asynchronously. An algorithm then is designed to implement our data aggregation under asynchronization. Finally, we implement our experiment on the basis of real test‐beds to prove that the scheme can save more energy than an existing algorithm for node selection, Distributive Online Greedy (DOG).

Background: Angiogenesis is implicated in many pathological conditions. The role of the proteins involved remains largely unknown, and few vascular‐specific drug targets have been discovered. Previously, in a screen for angiogenesis regulators, we identified Paladin (mouse: X99384, human: KIAA1274), a protein containing predicted S/T/Y phosphatase domains. Results: We present a mouse knockout allele for Paladin with a β‐galactosidase reporter, which in combination with Paladin antibodies demonstrate that Paladin is expressed in the vasculature. During mouse embryogenesis, Paladin is primarily expressed in capillary and venous endothelial cells. In adult mice Paladin is predominantly expressed in arterial pericytes and vascular smooth muscle cells. Paladin also displays vascular‐restricted expression in human brain, astrocytomas, and glioblastomas. Conclusions: Paladin, a novel putative phosphatase, displays a dynamic expression pattern in the vasculature. During embryonic stages it is broadly expressed in endothelial cells, while in the adult it is selectively expressed in arterial smooth muscle cells.

Influence of Morphology and Texture of CeO2 on YBa2Cu3O7 (YBCO) Growth and BaCeO3 Formation in Solution‐Derived Synthesis
Authors: Van de Velde Nigel , Bruggeman Tom , Stove Lander , Pollefeyt Glenn , Brunkahl Oliver , Van Driessche Isabel
Published: February 2012

When working with chemical solution deposition techniques, one of the main issues for optimal performance of CeO2 buffer layers in coated conductors is the insufficient chemical stability of the CeO2 layer during YBa2Cu3O7 (YBCO) thermal processing. This work focusses on the morphology and nanostructure in thin CeO2 films prepared by means of a novel aqueous synthesis route and incorporated into a Ni–W/La2Zr2O7/CeO2/YBa2Cu3O7‐coated conductor. Optimization of precursor chemistry and thermal processing led to a reduction in barium cerate formation. In a new precursor design, iminodiacetic acid was used as a stabilizing ligand, which resulted in an improved morphology of the buffer layer. A shelf life of more than 6 months was established by using a metal‐to‐ligand ratio of 1 to 5. During thermal processing, a combination of a slow calcination ramp with a high sintering ramp, short sintering dwell time and a low oxygen partial pressure during the synthesis resulted in a root mean square roughness below 3 nm for AFM analysis, a [111] to [002] ratio of 1 to 90 in X‐ray diffraction and well‐defined patterns in reflection high‐energy electron diffraction (RHEED) analysis of the CeO2 surface. Trifluoroacetate‐YBCO was deposited on top of the CeO2 buffer layer. Cross‐section analysis with a focussed ion beam allowed us to correlate the morphology and nanostructure of the CeO2 buffer layer with the formation of BaCeO3 and the appearance of voids and secondary phases throughout the YBa2Cu3O7 layer.
[V15Ge6O42S6(H2O)]12–, a Thiogermanatopolyoxovanadate Cluster Featuring the Spin Topology of the Molecular Magnet [V15As6O42(H2O)]6–

Published: February 2012

The new compound [Co(tren)(trenH2)]2[{Co(tren)}2V15Ge6O42S6(H2O)]·9H2O [1, tren = tris(2‐aminoethyl)amine] has been obtained under solvothermal conditions and features the unique thiogermanatovanadatopolyoxoanion[VIV15GeIV6O42S6(H2O)]12– as the main structural motif. Compound 1 crystallizes in the monoclinic space group P21/c with a = 15.4711(2), b = 26.4031(4), c = 26.7213(4) Å, V = 10874.2(3) Å3, and Z = 4. The [V15Ge6O42S6(H2O)]12– cluster anion displays the spin topology reported for the molecular magnets [VIV15AsIII6O42(H2O)]6– and [VIV15SbIII6O42]6– and therefore represents a new member of the {V15E6} family, which has allowed us to study the magnetic exchange interactions between the vanadyl (d1) groups of the geometrically frustrated central V3 triangle, which is sandwiched between strongly antiferromagnetically coupled V6 hexagons. The cluster shell is expanded by two {Co(tren)}2+‐based complexes through Co–S bonds, which reduce the high negative charge of the anion. The Co2+ ions in the [Co(tren)(trenH2)]4+ countercations are coordinated to one tetradentate tren and a monodentate, doubly protonated tren ligand.
The effects of social exclusion on confirmatory information processing
Authors: Greitemeyer Tobias , Fischer Peter , Kastenmüller Andreas
Published: February 2012

After making a preliminary decision, a balanced search for information that is consistent and inconsistent with one's decision is associated with effective decision making. However, whereas searching for information that is inconsistent with one's preliminary preference arouses the aversive motivational state of cognitive dissonance, evokes negative emotions, and threatens the self, preference‐consistent information reduces dissonance, evokes positive emotions, and has positive implications for the self. Thus, searching for information in a balanced way requires the willingness to face the negative implications of searching for preference‐inconsistent (relative to preference‐consistent) information. Social exclusion has been shown to be associated with impulsive, undercontrolled behavior. Therefore, we expected socially excluded (relative to included or control) participants to be less willing to confront oneself with the unappealing qualities of preference‐inconsistent information and more willing to seek for the appealing qualities of preference‐consistent information. This hypothesis was supported in two studies, with the use of different manipulations of social exclusion. Copyright © 2012 John Wiley & Sons, Ltd.
