Sulfur isotopic composition of surface snow along a latitudinal transect in East Antarctica
Authors: Uemura Ryu , Masaka Kosuke , Fukui Kotaro , Iizuka Yoshinori , Hirabayashi Motohiro , Motoyama Hideaki
Published: May 2016

The sulfur stable isotopic values (δ34S) of sulfate aerosols can be used to assess oxidation pathways and contributions from various sources, such as marine biogenic sulfur, volcanoes, and sea salt. However, because of a lack of observations, the spatial distribution of δ34S values in Antarctic sulfate aerosols remains unclear. Here we present the first sulfur isotopic values from surface snow samples along a latitudinal transect in eastern Dronning Maud Land, East Antarctica. The δ34S values of sulfate showed remarkably uniform values, in the range of 14.8–16.9‰, and no significant decrease toward the inland part of the transect was noted. These results suggest that net isotopic fractionation during long‐range transport is insignificant. Thus, the δ34S values can be used to infer source contributions. The δ34S values suggest that marine biogenic sulfur is the dominant source of sulfate aerosols, with a fractional contribution of 84 ± 16%.
Bottom pressure torque and the vorticity balance from observations in Drake Passage
Authors: Firing Yvonne L. , Chereskin Teresa K. , Watts D. Randolph , Mazloff Matthew R.
Published: May 2016

The vorticity balance of the Antarctic Circumpolar Current in Drake Passage is examined using 4 years of observations from current‐ and pressure‐recording inverted echo sounders. The time‐varying vorticity, planetary and relative vorticity advection, and bottom pressure torque are calculated in a two‐dimensional array in the eddy‐rich Polar Frontal Zone (PFZ). Bottom pressure torque is also estimated at sites across Drake Passage. Mean and eddy nonlinear relative vorticity advection terms dominate over linear advection in the local (50‐km scale) vorticity budget in the PFZ, and are balanced to first order by the divergence of horizontal velocity. Most of this divergence comes from the ageostrophic gradient flow, which also provides a second‐order adjustment to the geostrophic relative vorticity advection. Bottom pressure torque is approximately one‐third the size of the local depth‐integrated divergence. Although the cDrake velocity fields exhibit significant turning with depth throughout Drake Passage even in the mean, surface vorticity advection provides a reasonable representation of the depth‐integrated vorticity balance. Observed near‐bottom currents are strongly topographically steered, and bottom pressure torques grow large where strong near‐bottom flows cross steep topography at small angles. Upslope flow over the northern continental slope dominates the bottom pressure torque in cDrake, and the mean across this Drake Passage transect, 3 to
m s−2, exceeds the mean wind stress curl by a factor of 15–20.
Scale dependence of the hydraulic properties of a fractured aquifer estimated using transfer functions
Authors: Pedretti D. , Russian A. , Sanchez‐Vila X. , Dentz M.
Published: May 2016

We present an investigation of the scale dependence of hydraulic parameters in fractured media based on the concept of transfer functions (TF). TF methods provide an inexpensive way to perform aquifer parameter estimation, as they relate the fluctuations of an observation time series (hydraulic head fluctuations) to an input function (aquifer recharge) in frequency domain. Fractured media are specially sensitive to this approach as hydraulic parameters are strongly scale‐dependent, involving nonstationary statistical distributions. Our study is based on an extensive data set, involving up to 130 measurement points with periodic head measurements that in some cases extend for more than 30 years. For each point, we use a single‐porosity and dual‐continuum TF formulation to obtain a distribution of transmissivities and storativities in both mobile and immobile domains. Single‐porosity TF estimates are compared with data obtained from the interpretation of over 60 hydraulic tests (slug and pumping tests). Results show that the TF is able to estimate the scale dependence of the hydraulic parameters, and it is consistent with the behavior of estimates from traditional hydraulic tests. In addition, the TF approach seems to provide an estimation of the system variance and the extension of the ergodic behavior of the aquifer (estimated in approximately 500 m in the analyzed aquifer). The scale dependence of transmissivity seems to be independent from the adopted formulation (single or dual‐continuum), while storativity is more sensitive to the presence of multiple continua.
A Bamboo‐Like GaN Microwire‐Based Piezotronic Memristor
Authors: Liu Haitao , Hua Qilin , Yu Ruomeng , Yang Yuchao , Zhang Taiping , Zhang Yingjiu , Pan Caofeng
Published: May 2016

Bamboo‐like gallium nitride (GaN) microwires are synthesized via chemical vapor deposition (CVD) to fabricate piezotronic memristors. Defect boundary areas (DBAs) near the bamboo knots produce apparent switching between high and low resistance states upon sweeping of the magnitudes of the biased voltages across the GaN microwire‐based devices at room temperature. Furthermore, by coupling the piezoelectric and semiconducting properties in the GaN microwire, the piezotronic effect is introduced to effectively modulate the SET voltages via strain‐induced piezoelectric polarizations created at the DBA interface upon mechanical deformation. The experimental results indicate that the device remembered the most recent resistance states when the power is turned off, and the waveform is tunable because of the delayed switching effect. This work provides an alternative approach to the design and modification of memristors based on nanostructured piezoelectric semiconductors using the piezotronic effect.
Quantifying the Complex Pore Architecture of Hierarchical Faujasite Zeolites and the Impact on Diffusion

Published: May 2016

An exact knowledge of the architecture of complex pore networks and the impact on transport processes is critical to understand and optimize their integration in many functional solids. Here, a robust and versatile approach is demonstrated to quantitatively map pore constrictions within hierarchical faujasite‐type (Y and USY) zeolites, the most widely applied zeolitic materials in industry. Differential hysteresis scanning measurements by high‐resolution argon sorption coupled with an advanced modeling framework enable the derivation of the amount and size of pyramidal, constricted, and occluded mesopores. This yields unprecedented insight into the impact of widely practiced demetallation treatments on the porosity evolution and clearly highlights the interplay between the geometry of mesopores developed by a given treatment and those introduced by previously applied postsynthetic modifications. Based on the findings, the dynamic assessment by positron annihilation spectroscopy confirms the effectiveness of each mesopore type at enhancing the diffusion of ortho‐positronium within the crystal. The quantitative descriptors attained by these complementary techniques can revolutionize the design of porous materials for a wide range of applications.
In Vivo Probe of Lipid II‐Interacting Proteins
Authors: Sarkar Sourav , Libby Elizabeth A. , Pidgeon Sean E. , Dworkin Jonathan , Pires Marcos M.
Published: May 2016

β‐Lactams represent one of the most important classes of antibiotics discovered to date. These agents block Lipid II processing and cell wall biosynthesis through inactivation of penicillin‐binding proteins (PBPs). PBPs enzymatically load cell wall building blocks from Lipid II carrier molecules onto the growing cell wall scaffold during growth and division. Lipid II, a bottleneck in cell wall biosynthesis, is the target of some of the most potent antibiotics in clinical use. Despite the immense therapeutic value of this biosynthetic pathway, the PBP–Lipid II association has not been established in live cells. To determine this key interaction, we designed an unnatural d‐amino acid dipeptide that is metabolically incorporated into Lipid II molecules. By hijacking the peptidoglycan biosynthetic machinery, photoaffinity probes were installed in combination with click partners within Lipid II, thereby allowing, for the first time, demonstration of PBP interactions in vivo with Lipid II.
An Efficient Numerical Solution of Fractional Optimal Control Problems by using the Ritz Method and Bernstein Operational Matrix
Authors: Nemati Ali , Yousefi Sohrabali , Soltanian Fahimeh , Ardabili J.Saffar
Published: May 2016

This paper deals with the Ritz spectral method to solve a class of fractional optimal control problems (FOCPs). The developed numerical procedure is based on the function approximation by the Bernstein polynomials along with fractional operational matrix usage. The approximation method is computationally consistent and moreover, has a good flexibility in the sense of satisfying the initial and boundary conditions of the optimal control problems. We construct a new fractional operational matrix applicable in the Ritz method to estimate the fractional and integer order derivatives of the basis. As a result, we achieve an unconstrained optimization problem. Next, by applying the necessary conditions of optimality, a system of algebraic equations is obtained. The resultant problem is solved via Newton's iterative method. Finally, the convergence of the proposed method is investigated and several illustrative examples are added to demonstrate the effectiveness of the new methodology.

In this paper, we discuss the recursive stochastic H2/H∞ control problem of delay systems with random coefficients involving both continuous and impulse controls. By virtue of a new type of forward backward stochastic differential equations, a necessary and sufficient condition for the existence of a unique solution to the control problem under consideration is derived. The existence and uniqueness of the forward backward stochastic differential equations are also be proved.

Published: May 2016

Cutaneous blood flow provides nourishment that plays an essential role in maintaining skin health. We examined the effects of pulsed electromagnetic fields (PEMFs) on cutaneous circulation of dorsal feet. Twenty‐two patients with diabetes mellitus (DM) and 21 healthy control subjects were randomly allocated to receive either PEMFs or sham PEMFs (0.5 mT, 12 Hz, 30 min). Blood flow velocity and diameter of the small vein were examined by using ultrasound biomicroscopy; also, microcirculation at skin over the base of the 1st metatarsal bone (Flux1) and distal 1st phalange (Flux2) was measured by laser Doppler flowmetry before and after intervention. Results indicated that PEMFs produced significantly greater changes in blood flow velocity of the smallest observable vein than did sham PEMFs (both P < 0.05) in both types of subjects. However, no significant difference was found in changes of vein diameter, nor in Flux1 and Flux2, between PEMFs and sham PEMFs groups in subjects with or without DM. We hypothesized that PEMFs would increase blood flow velocity of the smallest observable vein in people with or without DM. Bioelectromagnetics. 37:290–297, 2016. © 2016 Wiley Periodicals, Inc.

The major components, 1‐hydroxy‐2,3,5‐trimethoxy‐xanthone (HM‐1) and 1,5‐dihydroxy‐2,3‐dimethoxy‐xanthone (HM‐5) isolated from Halenia elliptica D. Don (Gentianaceae), could cause vasodilatation in rat coronary artery with different mechanisms. In this work, high‐performance liquid chromatography coupled to ion trap time‐of‐flight mass spectrometry (LCMS‐IT‐TOF) was used to clarify the metabolic pathways, and CYP450 isoform involvement of HM‐1 and HM‐5 were also studied in rat. At the same time, in vivo inhibition effects of HM‐1 and ethyl acetate extracts from origin herb were studied. Three metabolites of HM‐5 were found in rat liver microsomes (RLMs); demethylation and hydroxylation were the major phase I metabolic reactions for HM‐5. Multiple CYP450s were involved in metabolism of HM‐1 and HM‐5. The inhibition study showed that HM‐5 inhibited Cyp1a2, 2c6 and 2d2 in RLMs. HM‐1 inhibited activities of Cyp1a2, Cyp2c6 and Cyp3a2. In vivo experiment demonstrated that both HM‐1 and ethyl acetate extracts could inhibit Cyp3a2 in rats. In conclusion, the metabolism of xanthones from the origin herb involved multiple CYP450 isoforms; in vitro, metabolism of HM‐5 was similar to that of its parent drug HM‐1, but their inhibition effects upon CYP450s were different; in vivo, Cyp3a2 could be inhibited by HM‐1 and ethyl acetate extracts.

The MDM2 protein plays an important role in the regulation of cell proliferation and apoptosis via ubiquitination and proteasome‐mediated degradation of p53. The genetic polymorphism rs2279744 (c.309T>G) of the MDM2 gene is reportedly associated with susceptibility and/or prognosis in various cancers. In this study, we investigated the risk factors for worse survival in patients with lung adenocarcinoma (AC). We examined the association between c.309T>G and the prognosis of lung cancer by retrospectively reviewing 453 lung cancer patients. We studied both, clinicopathological and genetic characteristics, including the c.309T>G, p53 Arg72Pro, EGFR, KRAS, and p53 mutations. Associations between these factors and survival outcome were analyzed using Cox proportional hazards models. The frequencies of MDM2 polymorphisms were T/T, 20.8%; T/G, 48.6%, and G/G, 30.7%. The overall survival (OS) of AC patients with pathological stage I disease and the MDM2 T/T genotype was significantly shorter than that of those with the T/G or G/G genotypes (P = 0.02). Multivariate analysis revealed that the MDM2 T/T genotype was an independent, significant prognostic factor (hazard ratio [HR] = 2.23; 95% confidence interval [CI]: 1.07–4.65; P = 0.03). The MDM2 T/T genotype was predictive of poorer survival in a Japanese population. Genotyping for this polymorphism might predict the clinical outcomes of stage I AC patients.
Determining personality traits of racing game players using the open racing car simulator: toward believable virtual drivers
Authors: Possani‐Espinosa Andre , Gutierrez‐Garcia J. Octavio , Vargas Gordillo Isaac
Published: May 2016

Believable artificial opponents, for example, believable virtual drivers, are fundamental to engage players and make (car racing) video games more entertaining. This paper lays the foundations for the design of believable virtual drivers by proposing a methodology for profiling players using the open racing car simulator. Data collected from 125 players about their driving behaviors and personality traits give insights into how personality traits should model the behavior of believable virtual drivers. The data analysis was conducted using a correlation analysis and the J48 decision tree algorithm. Empirical evidence shows that goal‐oriented driving behaviors can be used to determine personality traits of players. In addition, this work also (i) gives preliminary insights into the relationship between the driving behavior and personality of racing game players and actual car drivers; and (ii) presents evidence of the relevance of gender as a predictor of personality traits of racing game players.

Supramolecular Gels by Design: Towards the Development of Topical Gels for Self‐Delivery Application
Authors: Parveen Rumana , Dastidar Parthasarathi
Published: May 2016

Following a supramolecular synthon approach, simple salt formation has been employed to gain access to a series of supramolecular gelators derived from the well‐known non‐steroidal anti‐inflammatory drug (NSAID) ibuprofen. A well‐studied gel‐inducing supramolecular synthon, namely primary ammonium monocarboxylate (PAM), has been exploited to generate a series of PAM salts by reacting ibuprofen with various primary amines. Remarkably, all of the salts (S1–S7) thus synthesized proved to be good to moderate gelators of various polar and nonpolar solvents. Single‐crystal and powder X‐ray diffraction studies established the existence of the PAM synthons in the gel network, confirming the efficacy of the supramolecular synthon approach employed. Most importantly, the majority of the salts (S2, S3, S6, and S7) were capable of gelling methyl salicylate (MS), an important ingredient found in many commercial topical gels. In vitro experiments (MTT and PGE2 assays) revealed that all of the salts (except S3 and S7) were biocompatible (up to 0.5 mm concentration), and the most suited one, S6, displayed anti‐inflammatory ability as good as that of the parent drug ibuprofen. A topical gel of S6 with methyl salicylate and menthol was found to be suitable for delivering the gelator drug in a self‐delivery fashion in treating skin inflammation in mice. Histological studies, including immunohistology, were performed to further probe the role of the gelator drug S6 in treating inflammation. Cell imaging studies supported cellular uptake of the gelator drug in such biomedical application.
