SummaryThis paper addresses the problem of efficient federation formation by the cloud providers (CPs) with an aim to fulfill the dynamic resource demands of users for supporting data‐intensive workloads. Existing works only focus on forming federations based on the highest profit gained by each of the CPs in a federation. Therefore, these approaches often suffer from the risk of selecting unreliable CPs in the federation resulting in additional penalty cost and loss of CPs's reputation due to service level agreement violation between the users and the federation. In contrast, we argue that a trust model is necessary to find the most promising cloud collaborators. Accordingly, we propose a novel cloud federation formation mechanism by utilizing a trust‐based cooperative game theory, which enables the CPs to dynamically form a federation based on profit maximization and penalty cost minimization as a result of selecting the trustworthy CPs. Simulation results show that the cloud federation formed by the proposed mechanism is stable, satisfies the fairness property, and yields higher profit for the participating CPs in the long run without incurring penalty cost as compared with the state‐of‐the‐art approaches.

AbstractAn almost linear (<Mn‐Mn‐Mn=132.25°) trinuclear manganese(II) complex [Mn3(L)(N3)4]⋅2 H2O (1) of a decacoordinating N8O2 donor ligand, H2L, was synthesized and structurally characterized by means of single‐crystal X‐ray crystallography and mass spectrometry. All the MnII centers are in pseudo‐octahedral geometry and wrapped by a single decacoordinating N8O2 donor ligand. The central manganese atom (Mn2) is connected to two terminal manganese (Mn1 and Mn3) atoms by two bridging phenolate O atoms and two bridging azide N atoms. Compound 1 is the first example of a linear trinuclear model to show pronounced epoxidation of olefins by tert‐butylhydroperoxide (TBHP) with a turnover number (TON) greater than 950. Though epoxidation of olefins by m‐chloroperbenzoic acid (m‐CPBA) was found to be complete within 20 minutes of mixing, the conversion was not more than 40 % and corresponding alcohols were found to be major products, whereas with H2O2 as oxidant there was no visible catalytic epoxidation of olefins. Furthermore, the compound was characterized by temperature‐dependent magnetic susceptibility measurements and a total spin ground state of St=15/2 was found.

AbstractSelective oxidation of 1,6‐hexanediol into 6‐hydroxycaproic acid was achieved over hydrotalcite‐supported Au–Pd bimetallic nanoparticles as heterogeneous catalyst using aqueous H2O2. N,N‐dimethyldodecylamine N‐oxide (DDAO) was used as an efficient capping agent. Spectroscopic analyses by UV/Vis, TEM, XPS, and X‐ray absorption spectroscopy suggested that interactions between gold and palladium atoms are responsible for the high activity of the reusable Au40Pd60‐DDAO/HT catalyst.

Published: May 2015

ABSTRACTVangl2 plays a critical role in the establishment of planar cell polarity (PCP). Previously, we detected expression of Vangl2 in the developing retina during late embryogenesis, which led us to investigate the possible role of Vangl2‐mediated PCP signaling in eye development. We have generated a Vangl2BGeo knock‐in mouse allowing us to evaluate Vangl2 mRNA expression during retinal development, and used an isoform‐specific antibody to examine Vangl2 protein expression in cryosections. To investigate the role of Vangl2 in retinal development, we examined eyes taken from embryos homozygous for independent alleles of Looptail (Lp, Lpm1jus) mutant mice. We found that Vangl2 mRNA and protein are dynamically expressed in the developing embryonic and postnatal retina, with Vangl2 expression becoming progressively restricted to the ganglion cell layer and optic nerve as the retina matures. The expression pattern of Vangl2 transcript and protein is most prominent in retinal ganglion cells (RGC), and their axons. Additionally, we show that Vangl2 is required for retinal and optic nerve development as Vangl2 Lp/Lp mutant embryos display a significantly reduced eye size, marked thickening of the retina, and striking abnormalities in the morphology of the optic nerve (significant hypoplasia, and aberrant exit trajectory). Notably, we identified a salient intraretinal axon guidance defect in Vangl2 Lp/Lp mutant embryos through which axon bundles traverse the entire thickness of the retina and become trapped within the subretinal space. Our observations identify a new and essential role for Vangl2‐dependent PCP signaling in the intraretinal path‐finding of RGC axons. © 2015 Wiley Periodicals, Inc. Develop Neurobiol 76: 150–165, 2016
Preparation and evaluation of monodispersed, submicron, non‐porous silica particles functionalized with β‐CD derivatives for chiral‐pressurized capillary electrochromatography
Authors: Yangfang Lu , Hui Wang , Yun Xue , Xue Gu , Yan Wang , Chao Yan 
Published: May 2015

Submicron, non‐porous, chiral silica stationary phase has been prepared by the immobilization of functionalized β‐CD derivatives to isocyanate‐modified silica via chemical reaction and applied to the pressurized capillary electrochromatography (pCEC) enantio‐separation of various chiral compounds. The submicron, non‐porous, cyclodextrin‐based chiral stationary phases (sub_μm‐CSP2) exhibited excellent chiral recognition of a wide range of analytes including clenbuterol hydrochloride, mexiletine hydrochloride, chlorpheniramine maleate, esmolol hydrochloride, and metoprolol tartrate. The synthesized submicron particles were regularly spherical and uniformly non‐porous with an average diameter of around 800 nm and a mean pore size of less than 2 nm. The synthesized chiral stationary phase was packed into 10 cm × 100 μm id capillary columns. The sub_μm‐CSP2 column used in the pCEC system showed better separation of the racemates and at a higher rate compared to those used in the capillary liquid chromatography mode (cLC) system. The sub_μm‐CSP2 possessed high mechanical strength, high stereoselectivity, and long lifespan, demonstrating rapid enantio‐separation and good resolution of samples. The column provided an efficiency of up to 170 000 plates/m for n‐propylbenzene.

Published: May 2015

ABSTRACTBackgroundThe purpose of this study was to present the results of our investigation of malic enzyme (ME) expression and the induction of senescence in head and neck squamous cell carcinoma (HNSCC).MethodsP53, ME1, ME2, and aspects of cellular metabolism, such as reactive oxygen species (ROS) were investigated in HNSCC cell lines.ResultsBoth metformin and ionizing radiation inhibited the expression of ME2, but not ME1, in HNSCC. Knockdown of ME1 or ME2 potentiated therapy‐induced senescence in HNSCC cells regardless of p53 status, and led to increased p21 and generation of ROS. Therapy‐induced senescence in ME‐depleted cells was blocked by the antioxidant N‐acetyl cysteine. Finally, high expression of ME2 was associated with poorer overall survival (OS) in patients with HNSCC.ConclusionDepletion of ME enhances therapy‐induced senescence and seems driven largely by ROS. ME2 expression in HNSCC may be associated with poor outcome, providing a possible link between therapy‐induced senescence and patient outcome, and indicating a potential therapeutic benefit of targeting ME2. © 2015 Wiley Periodicals, Inc.

AbstractBackgroundThe purpose of this study was to examine outcomes, toxicity, and dosimetric characteristics of patients treated with reirradiation for head and neck cancers.MethodsFifty patients underwent ≥2 courses of radiation therapy (RT) postoperatively or definitively with or without chemotherapy. Composite dose volume histograms (DVHs) for selected anatomic structures were correlated with grade ≥3 late toxicity.ResultsMedian initial and retreatment radiation dose was 64 and 60 Gy, respectively. Median overall survival (OS), progression‐free survival (PFS), and 1‐year PFS rates were 18 months, 11 months, and 45%, respectively, with 13 months median follow‐up. Thirty‐four percent of patients experienced grade ≥3 late toxicity with 1 death from carotid blowout. The DVH corresponding to the carotid blowout fell above the third quartile compared with other patients.ConclusionOur analysis is the first to systematically evaluate the dose to the carotid artery using composite dosimetry in head and neck reirradiation patients, and demonstrates a promising technique for evaluating the dose to other normal tissue structures. © 2015 Wiley Periodicals, Inc.

What, Why, and How They Read
Authors: Becnel Kim , Moeller Robin A. 
Published: May 2015

AbstractThe purpose of this study is to better understand the reading patterns and preferences of rural teen readers and the cultures of reading that do or do not exist in the rural communities in which the teens reside. In addition, the researchers sought to discover, by conducting a series of focus groups, whether rural teen readers felt connected to mainstream young adult literary culture and in what ways this connection might manifest itself. The results suggest that rural teens enjoy reading books, followed by magazines and online content; that they obtain their reading materials through borrowing from friends and family and purchasing from retail outlets rather than from local libraries; that they talk to family, friends, and teachers about books and reading; and that they feel strongly connected to the current world of young adult literature, using it as a vehicle through which to explore and develop their evolving identities.

Published: May 2015

AbstractThe antibacterial properties of super‐hydrophobic silver (Ag) on implant surface have not yet to be fully illuminated. In our study, we investigate the protective effects of super‐hydrophobic coating of silver/titanium dioxide (Ag/TiO2) nanotubes against bacterial pathogens, as well as its pattern of Ag release. Ag/TiO2 nanotubes are prepared by a combination of electrochemical anodization and pulse electrodeposition. The super‐hydrophobic coating is prepared by modifying the surface of Ag/TiO2 nanotubes with 1H, 1H, 2H, 2H‐perfluorooctyl‐triethoxysilane (PTES). Surface features and Ag release are examined by SEM, X‐ray photoelectron spectroscopy, contact‐angle measurement, and inductively coupled plasma‐mass spectrometry (ICP‐MS). The antibacterial activity of super‐hydrophobic coating Ag/TiO2 nanotubes is investigated both in vitro and in vivo. Consequently, the super‐hydrophobic coating on Ag/TiO2 nanotubes shows a regularly arranged structure; and nano‐Ag particles (10–30 nm) are evenly distributed on the surface or inside the nanotubes. The contact angles of water on the super‐hydrophobic coating Ag/TiO2 nanotubes are all above 150°. In addition, the super‐hydrophobic character displays a certain conserved effect that contributes to the sustained release of Ag. The super‐hydrophobic Ag/TiO2 nanotubes are also effective in inhibiting bacterial adhesion, killing the adhering bacteria and preventing postoperative infection in rabbits. Therefore, it is expected that the super‐hydrophobic Ag/TiO2 nanotubes which can contain the release of Ag, leading to stable release, may show a consistent surface antibacterial capability. © 2015 Wiley Periodicals, Inc.

Cutaneous siderosis secondary to intramuscular iron dextran treated with 755 nm Q‐switched alexandrite laser: A case report
Authors: Lloyd Amanda A. , Graves Michael S. , Ross Edward V. 
Published: May 2015

BackgroundCutaneous siderosis is accumulation of iron in the dermis and the subcutaneous tissue secondary to extravasation of an intramuscular or intravascular iron injection. It presents as varying shades of brown macules with no distinct contours. The hyperpigmentation is permanent without treatment.ObjectiveQ‐switched lasers have been used effectively to treat lentigines and tattoos however, there is little data on the treatment of cutaneous siderosis with lasers. Our objective was to effectively treat cutaneous siderosis with a Q‐switched alexandrite laser.ResultsA 50‐year‐old female had received nine injections of intramuscular iron dextran, one injection every 2 weeks alternating right buttock and left buttock over the course of 5 months. A couple of weeks after her 9th injection which was on the left, she noted brown hyperpigmentation in the injection area with the left worse than the right. She waited 3 months for the hyperpigmentation to self‐resolve before presenting in our clinic. We utilized the Q‐switched alexandrite laser to treat the patient with a test spot. One week later, there was nice partial clearance from the test spot so we commenced full treatment of the hyperpigmentation. There was significant improvement after the first treatment and she has been treated 4 times with continued improvement over the past 2 months.ConclusionThe Q‐switched alexandrite laser is a useful tool in the treatment of cutaneous siderosis secondary to iron injection.

BDDC for mixed‐hybrid formulation of flow in porous media with combined mesh dimensions
Authors: Šístek Jakub , Březina Jan , Sousedík Bedřich 
Published: May 2015

SummaryWe extend the balancing domain decomposition by constraints (BDDC) method to flows in porous media discretised by mixed‐hybrid finite elements with combined mesh dimensions. Such discretisations appear when major geological fractures are modelled by one‐dimensional or two‐dimensional elements inside three‐dimensional domains. In this set‐up, the global problem and the substructure problems have a symmetric saddle‐point structure, containing a ‘penalty’ block due to the combination of meshes. We show that the problem can be reduced by means of iterative substructuring to an interface problem, which is symmetric and positive definite. The interface problem can thus be solved by conjugate gradients with the BDDC method as a preconditioner. A parallel implementation of this algorithm is incorporated into an existing software package for subsurface flow simulations. We study the performance of the iterative solver on several academic and real‐world problems. Numerical experiments illustrate its efficiency and scalability. Copyright © 2015 John Wiley & Sons, Ltd.
Proper generalized decomposition of a geometrically parametrized heat problem with geophysical applications
Authors: Zlotnik Sergio , Díez Pedro , Modesto David , Huerta Antonio 
Published: May 2015

SummaryThe solution of a steady thermal multiphase problem is assumed to be dependent on a set of parameters describing the geometry of the domain, the internal interfaces and the material properties. These parameters are considered as new independent variables. The problem is therefore stated in a multidimensional setup. The proper generalized decomposition (PGD) provides an approximation scheme especially well suited to preclude dramatically increasing the computational complexity with the number of dimensions. The PGD strategy is reviewed for the standard case dealing only with material parameters. Then, the ideas presented in [Ammar et al., “Parametric solutions involving geometry: A step towards efficient shape optimization.” Comput. Methods Appl. Mech. Eng., 2014; 268:178–193] to deal with parameters describing the domain geometry are adapted to a more general case including parametrization of the location of internal interfaces. Finally, the formulation is extended to combine the two types of parameters. The proposed strategy is used to solve a problem in applied geophysics studying the temperature field in a cross section of the Earth crust subsurface. The resulting problem is in a 10‐dimensional space, but the PGD solution provides a fairly accurate approximation (error ≤1%) using less that 150 terms in the PGD expansion.

Assignment of the Internal Vibrational Modes of C70 by Inelastic Neutron Scattering Spectroscopy and Periodic‐DFT
Authors: Refson Keith , Parker Stewart F. 
Published: May 2015

AbstractThe fullerene C70 may be considered as the shortest possible nanotube capped by a hemisphere of C60 at each end. Vibrational spectroscopy is a key tool in characterising fullerenes, and C70 has been studied several times and spectral assignments proposed. Unfortunately, many of the modes are either forbidden or have very low infrared or Raman intensity, even if allowed. Inelastic neutron scattering (INS) spectroscopy is not subject to selection rules, and all the modes are allowed. We have obtained a new INS spectrum from a large sample recorded at the highest resolution available. An advantage of INS spectroscopy is that it is straightforward to calculate the spectral intensity from a model. We demonstrate that all previous assignments are incorrect in at least some respects and propose a new assignment based on periodic density functional theory (DFT) that successfully reproduces the INS, infrared, and Raman spectra.
Comparing genetic counselor's and patient's perceptions of needs in prenatal chromosomal microarray testing
Authors: Walser Sarah A. , Kellom Katherine S. , Palmer Steven C. , Bernhardt Barbara A. 
Published: May 2015

What's already known about this topic?

Most women desire comprehensive education about prenatal screening and testing for genetic disorders, but little is known about their specific needs pre‐testing and post‐testing. To develop guidelines for return of uncertain and incidental findings from prenatal genomic testing, data are needed on women's preferences for return of various types of results.
What does this study add?

This study adds to the limited knowledge of women's informational and resource needs associated with prenatal chromosomal microarray analysis testing and is one of the only studies to assess attitudes toward return of results among patients who have personal experience with prenatal genomic testing.
Intraclass and interclass correlation coefficient‐based feature selection in NIDS dataset
Authors: Vasudevan Alampallam Ramaswamy , Selvakumar Subramanian 
Published: May 2015

AbstractOffline processing of network intrusion detection system (NIDS) dataset helps to mitigate network attacks. KDD CUP'99 was created using known network attacks in 1999. The changes in networking trend and advent of new attacks have raised the demand for new NIDS datasets. Recent test beds such as UNB‐ISCX, SSENet, and ITD‐UTM help in the evaluation and deployment of new network security algorithms. NIDS dataset generated from these test beds is used by the traditional feature selection methods, which focus on the whole dataset for the reduction of the number of features. Later, instead of whole dataset, selective dataset is used to choose the best feature set for a given attack. In this paper, the application of intraclass correlation coefficient and interclass correlation coefficient is proposed to achieve efficient target class‐specific feature subset. It is envisioned that such a feature subset would help in countering an attack type. Experiments were conducted on classification algorithms to validate on four datasets the effectiveness of the feature subsets on pairwise target class with and without applying our proposed feature selection algorithm. It is found that the detection rate increased and execution time and false alarms decreased considerably after applying the proposed feature selection algorithm.

Authors: Cazorla Mickaël , Gourgeon Sylvain , Marquet Kévin , Minier Marine 
Published: May 2015

AbstractFor security applications in wireless sensor networks (WSNs), choosing best algorithms in terms of energy‐efficiency and of small memory requirements is a real challenge because the sensor networks are composed of low‐power entities. In some previous works, 12 block‐ciphers have been benchmarked on an ATMEL AVR ATtiny45 8‐bit microcontroller and the best candidates to use in the context of small embedded platforms have been deduced. This article proposes to study on the TI 16‐bit microcontroller MSP430 most of the recent lightweight block cipher proposals as well as some conventional block ciphers. First, we describe the design of the chosen block ciphers with a security and an implementation summary and we then present some implementation tests performed on our dedicated platform.
