Enhanced Electrochemical Performance of PEO-Based Composite Polymer Electrolyte with Single-Ion Conducting Polymer Grafted SiO2 Nanoparticles

In order to enhance the electrochemical performance and mechanical properties of poly(ethylene oxide) (PEO)-based solid polymer electrolytes, composite solid electrolytes (CSE) composed of single-ion conducting polymer-modified SiO2, PEO and lithium salt were prepared and used in lithium-ion batteries in this work. The pyridyl disulfide terminated polymer (py-ss-PLiSSPSI) is synthesized through RAFT polymerization, then grafted onto SiO2 via thiol-disulfide exchange reaction between SiO2-SH and py-ss-PLiSSPSI. The chemical structure, surface morphology and elemental distribution of the as-prepared polymer and the PLiSSPSI-g-SiO2 nanoparticles have been investigated. Moreover, CSEs containing 2, 6, and 10 wt% PLiSSPSI-g-SiO2 nanoparticles (PLi-g-SiCSEs) are fabricated and characterized. The compatibility of the PLiSSPSI-g-SiO2 nanoparticles and the PEO can be effectively improved owing to the excellent dispersibility of the functionalized nanoparticles in the polymer matrix, which promotes the comprehensive performances of PLi-g-SiCSEs. The PLi-g-SiCSE-6 exhibits the highest ionic conductivity (0.22 mS·cm−1) at 60 °C, a large tLi+ of 0.77, a wider electrochemical window of 5.6 V and a rather good lithium plating/stripping performance at 60 °C, as well as superior mechanical properties. Hence, the CSEs containing single-ion conducting polymer modified nanoparticles are promising candidates for all-solid-state lithium-ion batteries.

HIF1α/CCL7/KIAA1199 axis mediates hypoxia-induced gastric cancer aggravation and glycolysis alteration

Gastric cancer is a common digestion tumor with high malignant severity and prevalence. Emerging studies reported C-C motif chemokine ligand 7 (CCL7) as a regulator of various tumor diseases. Our research explored the function and underlying mechanism of CCL7 during gastric cancer development. RT-qPCR, Western blot and other datasets were employed to evaluate CCL7 expression in tissues and cells. Kaplan–Meier and Cox regression analyses were recruited to evaluate the correlations between CCL7 expression and patients’ survival or clinical features. A loss-of-function assay was performed to evaluate the function of CCL7 in gastric cancer. 1% O2 was utilized to mimic hypoxic condition. KIAA1199 and HIF1α were included in the regulatory mechanism. The results showed that CCL7 was up-regulated and its high expression was correlated with poor survival of gastric cancer patients. Depressing CCL7 attenuated proliferation, migration, invasion, and induced apoptosis of gastric cancer cells. Meanwhile, CCL7 inhibition weakened hypoxia-induced gastric cancer aggravation. Besides, KIAA1199 and HIF1α were involved in the mechanism of CCL7-mediated gastric cancer aggravation under hypoxia. Our research identified CCL7 as a novel tumor-activator in gastric cancer pathogenesis and hypoxia-induced tumor aggravation was regulated by HIF1α/CCL7/KIAA1199 axis. The evidence may provide a novel target for gastric cancer treatment.
Observations of motional Stark features in the Balmer spectrum of deuterium in the JET plasma

Observations are reported of resolved components of deuterium Balmer emission in neutral beam heated JET plasmas. The features are interpreted as Doppler-shifted emission from deuterium in the neutral beams spectrally resolved into components by the nu *B motional Stark electric field. The mechanisms of excitation of the deuterium are elucidated and the emission modelled. Attention is drawn to the diagnostic potential of the observations for measurement of local magnetic fields, deuteron density and effective plasma ion charge.
Vector-Indistinguishability: Location Dependency Based Privacy Protection for Successive Location Data

With the wide use of GPS enabled devices and Location-Based Services, location privacy has become an increasingly worrying challenge to our community. Existing approaches provide solid bases for addressing this challenge. However, they mainly focus on independent location perturbation or whole trajectory perturbation with little attention to location dependency based perturbation between two successive locations. This may result in that perturbed successive locations lose mutual distance and direction dependency, which in turn can lead to significant data utility loss. To address this problem, we propose a new location dependency based privacy notion named as vector-indistinguishability (vector-ind). Vector-ind defines a vector to represent the dependency relationship between two successive locations. Correspondingly, it consists of distance-indistinguishability for distance dependency and direction-indistinguishability for direction dependency. Noise generation for applying Differential Privacy is based on the distance and direction, hence can reflect the location dependency to ensure data utility after perturbation. We also present four mechanisms to achieve vector-ind notion. Finally, we evaluate the empirical privacy and utility of vector-ind in real-world GPS data to demonstrate how our proposed mechanisms for vector-ind can protect location privacy with high data utility in successive location data.
WISHE‐Moisture Mode in an Aquaplanet Simulation

This study aims to understand the nature of the tropical intraseasonal oscillations (ISOs) in an aquaplanet simulation performed using Geophysical Fluid Dynamics Laboratory's AM2.1 with a uniform sea surface temperature within the deep tropics. The simulated ISO resembles the observed Madden‐Julian Oscillation in that the spectral peak in precipitation appears at zonal wave number 1 and a period of ~60 days. Vertically integrated moist static energy budget of the simulated ISO shows that enhanced latent heat flux to the east of anomalously active convection causes eastward propagation of the ISO mode, which is weakly opposed by horizontal moisture advection. A series of mechanism denial experiments are conducted either by homogenizing select variables—surface wind stress, longwave radiative heating, and surface evaporation—with their zonal means from the control simulation or by suppressing free‐tropospheric moisture variation. Results of the mechanism denial experiments show that the simulated ISO disappears when the interactive surface evaporation is disabled, suggesting that the wind‐induced surface heat exchange (WISHE) mechanism is essential to the simulated ISO. Longwave cloud‐radiation feedbacks and moisture‐convection feedbacks affect horizontal scale and phase speed of the simulated ISO, respectively. Our results strongly suggest that the simulated ISO is the linear WISHE‐moisture mode of Fuchs and Raymond under horizontally uniform boundary conditions.
Thermal Atomic Layer Etching of MoS2 Using MoF6 and H2O

Two-dimensional (2D) layered materials offer unique properties that make them attractive for continued scaling in electronic and optoelectronic device applications. Successful integration of 2D materials into semiconductor manufacturing requires high-volume and high-precision processes for deposition and etching. Several promising large-scale deposition approaches have been reported for a range of 2D materials, but fewer studies have reported removal processes. Thermal atomic layer etching (ALE) is a scalable processing technique that offers precise control over isotropic material removal. In this work, we report a thermal ALE process for molybdenum disulfide (MoS2). We show that MoF6 can be used as a fluorination source, which, when combined with alternating exposures of H2O, etches both amorphous and crystalline MoS2 films deposited by atomic layer deposition. To characterize the ALE process and understand the etching reaction mechanism, in situ quartz crystal microbalance (QCM), Fourier transform infrared (FTIR), and quadrupole mass spectrometry (QMS) experiments were performed. From temperature-dependent in situ QCM experiments, the mass change per cycle was −5.7 ng/cm2 at 150 °C and reached −270.6 ng/cm2 at 300 °C, nearly 50× greater. The temperature dependence followed Arrhenius behavior with an activation energy of 13 ± 1 kcal/mol. At 200 °C, QCM revealed a mass gain following exposure to MoF6 and a net mass loss after exposure to H2O. FTIR revealed the consumption of Mo–O species and formation of Mo–F and MoFx=O species following exposures of MoF6 and the reverse behavior following H2O exposures. QMS measurements, combined with thermodynamic calculations, supported the removal of Mo and S through the formation of volatile MoF2O2 and H2S byproducts. The proposed etching mechanism involves a two-stage oxidation of Mo through the ALE half-reactions. Etch rates of 0.5 Å/cycle for amorphous films and 0.2 Å/cycle for annealed films were measured by ex situ ellipsometry, X-ray reflectivity, and transmission electron microscopy. Precisely etching amorphous films and subsequently annealing them yielded crystalline, few-layer MoS2 thin films. This thermal MoS2 ALE process provides a new mechanism for fluorination-based ALE and offers a low-temperature approach for integrating amorphous and crystalline 2D MoS2 films into high-volume device manufacturing with tight thermal budgets.
Epsilon Approximate Solutions for Multiobjective Programming Problems

Abstract In this paper, approximate solutions for multiobjective programming problems up to ϵ(>0) are investigated. The concepts of approximate solutions were introduced by White and Loridan. The connections with these concepts are studied. Also, the sufficient and necessary conditions to obtain the elements of the smallest approximate solution set are verified.
Selenium Exerts an Intriguing Alteration of Primary and Secondary Plant Metabolites: Advances, Challenges, and Prospects

Abstract Selenium (Se) is not yet conclusively classified as an essential nutrient required for plant growth. However, much attention has been devoted to its important role in human health since Se enrichment affects the production of primary and secondary metabolites. A strong link between low levels of Se and cancer and cardiac diseases has been proven. Thus, Se enrichment of crops has been established as a pioneering strategy to enhance Se intake by animals and humans. It has been proven that Se biofortification through a foliar application or in the growth medium has increased Se levels in plant tissues without loss of productivity or qualitative properties. However, to achieve the desirable level of Se and promote human health, Se accumulation in plants should be quantified and balanced because Se enrichment may affect their nutrient balance. This timely review provides a broad overview of the metabolic changes induced in plants by Se enrichment. Additionally, it highlights the contrasting effects of Se biofortification on the up-and-down-regulation of several secondary metabolites including phenolics, flavonoids, and their derivatives, as well as glucosinolates.
On the Stone-Čech bicompactification of a bispace

Abstract In this paper we study the Stone-Čech bicompactification () of the bispace (X, P, Q). We show that the ring of all continuous real-valued functions on () may be identified with the uniform closure of a suitable subring of C(). Using this result, we give a characterization of the Wallman-Sanin compactifications of the pairwise Tychonoff bitopological spaces.
D’Alembert’s Paradox

Since classical inviscid theory leads to the patently absurd conclusion that the resistance experienced by a rigid body moving through a fluid with uniform velocity is zero, great efforts have been made during the last hundred or so years to propose alternate theories and to explain how a vanishingly small frictional force in the fluid can nevertheless have a significant effect on the flow properties. The methods used are a combination of experimental observation, computation often on a very large scale, and analysis of the structure of the asymptotic form of the solution as the friction tends to zero. This three-pronged attack has achieved considerable success, especially during the last ten years, so that now the paradox may be regarded as largely resolved. The lecture will review these achievements in subsonic and supersonic flow, for bluff bodies, for trailing-edge flows and for internal flows. Most of the work has been on steady two-dimensional problems but the special difficulties in unsteady and th.
Geometrical Effects on the Near-Field Flow Structure of Coaxial Jets

This study focuses on the effects of the geometry of the coaxial injectors on the near-field flow structure. The dependence of the flow structure on the annular gap e = (D 2 - D 1 )/2 is considered. The effect of the exit velocity profile is discussed. The consequences of a retraction of the inner tube on the coaxial jet flow dynamics is investigated too
Electronic and lattice contributions to the thermal conductivity of graphite intercalation compounds

The stage and temperature dependences of the in-plane thermal conductivity of graphite-FeCl/sub 3/ acceptor intercalation compounds are reported and analyzed, as well as the temperature dependence of a stage-5 potassium donor compound. The measured thermal conductivity is tentatively separated into an electronic contribution, which is dominant at low temperatures, and a lattice contribution, which is dominant around room temperature. Quantitative information is provided about lattice defects which are introduced by intercalation and scatter both electrons and phonons. Below room temperature in the in-plane lattice thermal conductivity is reduced by about an order of magnitude relative to pristine graphite due to an equivalent decrease in boundary scattering length and, to a lesser extent, to point defect scattering. Electron and phonon scattering is only weakly stage dependent. Data for the /b c/-axis thermal conductivity of a stage-2 FeCl/sub 3/ and a stage-5 potassium compound are also presented and discussed.
Wigner distribution function of DBR tapered diode lasers

In this paper, we utilize the concept of the Wigner distribution function (WDF) on distributed-Bragg-reflector taper lasers (DBR-TPL). The WDF allows the derivation of the phase and the intensity distribution just as well as the spatial coherence properties of the laser beam. For a given single-mode fiber the coupling efficiency for a given beam and optical system can be obtained by means of a simple overlap integral. Simultaneously, this approach delivers the corresponding beam forming requirements to meet the optimum coupling condition. We found a good agreement between the measured coupling efficiencies of the DBR-TPL into a single-mode fiber under varying coupling conditions and the corresponding efficiencies derived from the measured WDF by simulating the same coupling conditions.
The Effect of Kosher Determinants of Beef on Its Color, Texture Profile and Sensory Evaluation

Traditional ritual slaughter is an underlying practice in religious Jewish communities and it translates into eating in accordance with core beliefs. This paper aims to comprehensively analyze factors determining the kosher status of beef (sex, slaughter method, and muscle type) and assess their impact on selected quality properties, such as color or texture profile. Sensory evaluation was also performed. The muscles were obtained from 80 carcasses (50% of heifers and 50% of young bulls). The experimental results indicate that each studied kosherness determinant influenced beef quality properties. The process of koshering caused the darkening of beef and lowered the share of color parameters red (a*) and yellow (b*). The influence of the type of slaughter on the values of adhesiveness, gumminess, and chewiness of beef was confirmed; higher values were mostly obtained in the muscles of cattle from kosher slaughter. As to sensory evaluation, the study showed that in the case of muscle type, the sex and slaughter method positively influenced only some of the properties.
Complex three‐dimensional microstructural permeability prediction of porous fibrous media with and without compaction

Much of the work in permeability prediction has so far been done with respect to the in‐plane properties. Guided by Darcy's law, the in‐plane permeabilities (i.e. Kxx and Kyy) have been well characterized by researchers both experimentally and, to some extent, analytically and numerically. Work on transverse or through thickness permeability, however, has been sparse. Owing to the fact that the limited length scale in the through thickness direction of most fibre preforms makes transverse permeability a difficult value to measure experimentally, the objective of the present development is to study the feasibility of applying the methodology proposed by the authors in a previous work for in‐plane permeability prediction to the estimation of transverse, as well as the in‐plane, permeability of a typical 3D woven fibre preform. The additional objective of this work is to present a preliminary study on the effects of fibre mat compression on the fibre preform permeability. Copyright © 2004 John Wiley & Sons, Ltd.
Nondestructive thickness measurement of biological layers at the nanoscale by simultaneous topography and capacitance imaging

Nanoscale capacitance images of purple membrane layers are obtained simultaneously to topography in a nondestructive manner by operating alternating current sensing atomic force microscopy in jumping mode. Capacitance images show excellent agreement with theoretical modeling and prove to be a noninvasive method for measuring the thickness of purple membrane layers beyond the single monolayer limit with nanoscale lateral spatial resolution. With the ability of spatially resolving the capacitance while preserving the sample from damaging, this technique can be applied for nanoscale thickness measurement of other biological layers and soft materials in general.
Negative differential mobility in GaAs at ultrahigh fields: Comparison between an experiment and simulations

Direct measurement of the electron velocity vn at an extreme electric field E is problematic due to impact ionization. The dependence vn(E) obtained by a Monte Carlo method can be verified, however, by comparing simulated and experimental data on superfast switching in a GaAs bipolar transistor structure, in which the switching transient is very sensitive to this dependence at high electric fields (up to 0.6MV∕cm). Such a comparison allows the conclusion to be made that the change from negative to positive differential mobility predicted earlier at E∼0.3MV∕cm should not happen until the electric field exceeds 0.6MV∕cm.
Chronotype, Time of Day, and Performance on Intelligence Tests in the School Setting

Research suggests the existence of an association between chronotype and intellectual performance, but the nature of this link remains unclear. Studies conducted in a laboratory setting point to the synchrony effect (better performance at a person’s preferred time of day) for fluid intelligence, but not for crystallized intelligence, whereas studies that have analyzed students’ grades suggest that the effect exists for both. In the present study, we aimed to verify the synchrony effect by applying direct measures of crystallized intelligence, fluid intelligence, and subjective sleepiness–alertness in a sample of high school students during their morning or afternoon class. The results revealed a synchrony effect for crystallized, but not for fluid intelligence. During morning class, students with a morning chronotype performed better than evening chronotypes on a test of crystallized intelligence, whereas during afternoon class there was no difference between chronotypes. The association resulted from decreased performance during morning class in evening chronotypes that improved during afternoon class and constant performance in morning chronotypes. These effects were independent of sleepiness–alertness levels. The results suggest that individual differences between chronotypes may be important for tasks performed during morning classes, but not during afternoon ones, and that performance across school days may depend on time of day in evening chronotypes.
End-of-Life Health-Care Cost of Patients With Lung Cancer: A Retrospective Study

Introduction: Lung cancer exerts a significant societal and health-care–related economic burden and chemotherapy drugs constitute a major factor of total direct cost. The aim of the present study was to assess the direct health-care cost of lung cancer in Greece by conducting a retrospective analysis on the last 6 months of life. Methods: The present study was based on both the medical data and costs of treatment of deceased adult patients who suffered from terminal stage IIIB/IV lung cancer (non-small cell lung cancer and small cell lung cancer) during the last 6 months of their life. The study’s protocol was approved by the Hospital’s Research Ethics Committee. Costs included outpatient (outpatient services) and inpatient (inpatient services) costs. Descriptive statistics were mainly used for statistical analysis. Results: The files of 144 patients were analyzed. The total cost of health-care services for the study population during the last 6 months of life was attributed by 57% to inpatient services, whereas chemotherapy costs (74%) comprised the largest proportion of the total inpatient cost. The highest expenditure for outpatient services was attributed to concomitant medication (59%), followed by the cost of tests (21%) and radiotherapy (20%). Conclusions: The results of our study indicate that both inpatient and outpatient costs were substantial. The main inpatient and outpatient cost drivers were chemotherapy and concomitant medication, respectively. A more comprehensive nationwide study would be useful to validate our results and to include also indirect costs of cancer care in Greece.
MOBILE SINK PATH FORMATION TO EXTEND THE NETWORK LIFETIME IN WSN

: Wireless Sensor Network (WSN) is a group of sensor nodes that is utilized to observe and record the several physical, environmental, and significant real time data.Data traffic obtained through the Base Station (BS) in WSN minimizes the energy of close sensor nodes as equated to other sensor nodes. This issue is called as hot spot issue in the WSN. But, the Mobile Sink (MS) is proposed for solving this hot spot issue in the WSN. MS is used to gather the modified information from the Cluster Head (CH) and it forward to the BS. This approach presents a Mobile Sink Path Estimation (MSPE) to extend the network lifetime in WSN. The major objective of this article is to designing a MS route to minimizing the energy utilization and delay. In this approach each CH has a threshold level of the load ahead of that if there is an inflow of data, then the node routinely forwards an Mobile Sink Route Request (MS_REQ) for assist from the MS. Depend on the requests received from all CH nodes; the MS evaluates the most appropriate region to move other position. We examine the function of MSPE approach by applying Network simulator. Simulation results demonstrate that the introduced MSPE approach has enhanced the residual energy and minimized the network delay.
Asymptotic behavior of the covariation and the codifference for arma models with stable innovations

In this paper two measures of dependence - the covariation, CV, and the codifference, CD. - are considered. They extend the covariance function and are defined for ARMA processes with symmetric α-stable innovations. The asymptotic behavior of both measures is investigated for 1 < α < 2 in order to determine the cases when the codifference and the covariation are asymptotically proportional with the coefficient of proportionality equal to α.
