Unlocking and sharing data in astronomy
Authors: Henneken Edwin 
Published: May 2015

EDITOR'S SUMMARYThe astronomy community has been a leader in efforts to preserve and share research data to facilitate ongoing discoveries. Since some efforts have led to isolated and abandoned websites, the need to deposit data in specifically designed and maintained repositories is now recognized. These repositories may apply persistent data identifiers to data products including large and small datasets, software and raw data throughout the research cycle. Researchers should be encouraged to deposit and share data, but guidelines and practices are inconsistent and publishers' policies vary. Agreement among stakeholders must be found on clearly defined standards for data citation and linking through publications. Establishing and complying with citation standards for all related data products will promote data discovery and reuse.

Published: May 2015

AbstractAlthough activity‐based protein profiling (ABPP) has been used to study a variety of enzyme classes, its application to intramembrane proteases is still in its infancy. Intramembrane proteolysis is an important biochemical mechanism for activating proteins residing within the membrane in a dormant state. Rhomboid proteases (intramembrane serine proteases) are embedded in the lipid bilayers of membranes and occur in all phylogenetic domains. The study of purified rhomboid proteases has mainly been performed in detergent micelle environments. Here we report on the reconstitution of rhomboids in liposomes. Using ABPP, we have been able to detect active rhomboids in large and giant unilamellar vesicles. We have found that the inhibitor profiles of rhomboids in micelles and liposomes are similar, thus validating previous inhibitor screenings. Moreover, fluorescence microscopy experiments on the liposomes constitute the first steps towards activity‐based imaging of rhomboid proteases in membrane environments.

Published: May 2015

AbstractA fast and sensitive colorimetric assay (FRED, fast and reliable ene‐reductases detection) that allows the estimation of levels of conversion of ene‐reductase (ER)‐catalysed reactions has been developed. The activated olefin is reduced by ER at the expense of NAD(P)H cofactor, whose regeneration is carried out in situ by the glucose/glucose dehydrogenase system. Subsequently, the consumption of the co‐substrate glucose is determined colorimetrically by a multienzymatic system. The FRED assay offers a wide range of possible applications, from enzyme fingerprinting and kinetic analysis, to primary screening of enzyme libraries and optimisation of ERs' performances under different reaction conditions.

AbstractGrafting material for vaginal reconstruction commonly includes the bowel, peritoneum, skin, and amniotic membrane. Bone marrow mesenchymal stem cells (MSCs) have the potential of multilineage differentiation into a variety of cells and have been widely explored in tissue engineering. In the current study, we examined whether MSCs could be differentiated to vaginal epithelial cells (VECs) upon co‐culturing with VECs. We also examined whether Wnt/β‐catenin signaling pathway is implicated in such differentiation. Co‐culture of MSCs with VECs using a transwell insert system (with no direct contact) induced the expression of VECs marker AE1/AE3 in MSCs. MSCs combined with small intestinal submucosa (SIS) scaffold were implanted in place of the native vagina in rats to observe the implications for vaginal reconstruction in vivo. Anatomic repair of neovagina was assessed by histological staining for H/E and Masson's Trichrome. GSK‐3β and β‐catenin, main members of Wnt/β‐catenin signaling pathway, in MSCs were increased upon co‐culturing with VECs. Exposure of co‐cultured MSCs to a Wnt/β‐catenin signaling activator, lithium chloride (LiCl, 20 µM) increased phosphorylated GSK‐3β and β‐catenin and enhanced expression of AE1/AE3. In vivo‐grafted cells displayed significant matrix infiltration and expressed epithelial markers in neovagina. These findings suggest that MSCs could acquire the phenotype of VECs when co‐cultured with VECs, possibly via activation of Wnt/β‐catenin signaling. MSCs provide an alternative cell source for potential use in vaginal tissue engineering.

Published: May 2015

SummaryIn this paper, we demonstrate some speedup opportunity regarding Monte Carlo simulation on graphic processing unit architecture, with financial application. We leverage on the possibility of reducing the volume of actually generated random numbers, by replacing the generation phase with some shuffling using Compute Unified Device Architecture's built‐in shuffle instructions. We will study various shuffling patterns and duration, elect the best among them with regard to induced correlation, using Granger causality test. We will then study the accuracy and variance of results actually achieved by our general‐purpose computing on graphic processing unit shuffled Monte‐Carlo, exhibiting a computational time reduced by half while error remains marginal.

Published: May 2015

AbstractThermal annealing of nanodiamonds with diameters of a few nanometers (in an inert atmosphere and at temperatures in the range: 1500–1800 °C) leads to the formation of carbon nano‐onions (CNOs) with diameters between 5 and 6 nm, which correspond to nanostructures with six to eight graphitic layers. The resulting spherical CNO structures were thermally modified under different atmospheres and characterized by SEM, TEM, thermogravimetric analysis and spectroscopic (Raman and diffuse reflectance infrared Fourier transform/FTIR) spectroscopy. The electrochemical properties of the CNOs prepared under different conditions were determined and compared. The results reveal that the CNOs show different structures with predominant spherical “small” carbon nano‐onions. The aim of this article is to investigate the impact of the CNO′s synthesis conditions on the resulting structures and study the effect of further thermal modifications on the sizes, shapes and homogeneity of these carbon nanostructures.
Kinetic Modeling of Vacuum Residue Thermal Cracking in the Visbreaking Process Using Multiobjective Optimization
Authors: Taghipour Alireza , Naderifar Abbas 
Published: May 2015

AbstractA discrete six‐lump kinetic model for the thermal cracking of vacuum residue in the visbreaking process has been developed, and the time‐dependent behavior of each individual lump has been determined. A combination of the heuristic method and gradient‐based method (hybrid method) has been taken into account to optimize the parameters of the model. A new concept of objective functions has been presented and applied for optimization, so more acceptable results have been obtained. Such an approach has not been presented before. A number of 60 parameters was considered primarily, which has been reduced to 36 with the aim of flash calculation information, and optimized. The obtained results are in good agreement with experimental data. The analysis of the estimated rate constants showed that the cracking of vacuum residue to lighter products was the more dominant reaction pathway during the visbreaking process over the temperature range of 400–430 °C.

Published: May 2015

AbstractMethane is important in future energy schemes. The main strategies for storing and transporting methane are compression, liquefaction, and physical adsorption in synthetic porous materials. Here, we show that methane can be stored in a hydrated form using natural amino acids such as leucines as effective promoters to form methane hydrate with a high formation rate and a high capacity. In addition, the methane hydrate formed from the L‐leucine solution dissociates without foaming phenomenon. We also showed that the heavier hydrocarbons in natural gas can enhance the promoting effect of L‐leucine.
Can Households Cope with Health Shocks in Vietnam?
Authors: Mitra Sophie , Palmer Michael , Mont Daniel , Groce Nora 
Published: May 2015

AbstractThis paper investigates the economic impact of health shocks on working‐age adults in Vietnam during 2004–2008, using a fixed effects specification. Health shocks cover disability and morbidity and are measured by ‘days unable to carry out regular activity’, ‘days in bed due to illness/injury’, and ‘hospitalization’. Overall, Vietnamese households are able to smooth total non‐health expenditures in the short run in the face of a significant rise in out‐of‐pocket health expenditures. However, this is accomplished through vulnerability‐enhancing mechanisms, especially in rural areas, including increased loans and asset sales and decreased education expenditures. Female‐headed and rural households are found to be the least able to protect consumption. Results highlight the need to extend and deepen social protection and universal health coverage. © 2015 The Authors.Health Economicspublished by John Wiley & Sons Ltd.

Published: May 2015

Objectives/HypothesisTo determine the pediatric age groups viable for nasoseptal flap (NSF) reconstruction of endoscopic endonasal approaches (EEA) to intracranial pathology of suprasella neoplasms.Study DesignRetrospective cohort study.MethodsRetrospective review of 16 pediatric patients who underwent EEA with NSF reconstruction for a suprasellar defect from 2012 to 2014. Radioanatomic analysis was utilized to assess feasibility of NSF reconstruction of suprasellar neoplasms approached via EEA. Computed tomography (CT) measurements for defect size and potential flap coverage were measured by preoperative maxillofacial CT. Radiographic measurements and surgical outcomes were compared to determine if flap size would be sufficient to cover said defects in two pediatric age groups: those >10 years of age (mean age 14 years) and those <10 years (mean age 6 years).ResultsOf all patients encountered in this cohort, one postoperative cerebrospinal fluid leak was identified in the >10 years of age population, and this was not due to insufficient flap coverage. Average potential flap length and width are sufficient to cover average suprasellar defect length and width in both age groups (P < .05 in all age groups).ConclusionsPatient selection is critical for successful pediatric EEA. Preoperative radiographic assessment of NSF feasibility is a critical to ensure adequate flap coverage for suprasellar defects. NSF appears to provide a sufficient and reliable coverage option in reconstruction of suprasellar defects in pediatric patients.Level of Evidence4. Laryngoscope, 125:2451–2456, 2015

Published: May 2015

ABSTRACTThis article proposes a design of the 2.45‐GHz radio frequency identification tag antenna with a small size of 30 × 7.3 × 0.5 mm3. The proposed antenna consists of two radiating elements: one is a combination of the first‐order Hilbert fractal structure and the folded dipole; the other is the bent dipole. The interaction between two radiating parts makes the proposed antenna a 150 MHz broad bandwidth covering 2.37–2.52 GHz and a 2‐dB gain across the operating frequency band. Simulated and measured results validate the good performance of the proposed tag antenna. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1905–1908, 2015
