Temperature effects on the nonstationary Karpman–Washimi ponderomotive magnetization in quantum plasmas

The temperature effects on the nonstationary Karpman–Washimi ponderomotive magnetization are investigated in quantum Fermi plasmas. The cyclotron frequency due to the ponderomotive force of the electromagnetic wave has been obtained as a function of the Fermi Debye length and quantum wavelength. It is found that the Karpman–Washimi ponderomotive magnetization decreases with increasing Fermi temperature. The maximum position of the Fermi Debye length is found to be increased with an increase in the frequency in the small Fermi Debye length domain. It is also shown that the Fermi ponderomotive magnetization decreases with increasing frequency in the large Fermi Debye length domain. In addition, it is shown that the frequency dependence on the ponderomotive magnetization diminishes with increasing Fermi temperature.
Dietary Transfer of Zinc Oxide Nanoparticles Induces Locomotive Defects Associated with GABAergic Motor Neuron Damage in Caenorhabditis elegans

The widespread use of zinc oxide nanoparticles (ZnO-NPs) and their release into the environment have raised concerns about the potential toxicity caused by dietary transfer. However, the toxic effects and the mechanisms of dietary transfer of ZnO-NPs have rarely been investigated. We employed the bacteria-feeding nematode Caenorhabditis elegans as the model organism to investigate the neurotoxicity induced by exposure to ZnO-NPs via trophic transfer. Our results showed that ZnO-NPs accumulated in the intestine of C. elegans and also in Escherichia coli OP50 that they ingested. Additionally, impairment of locomotive behaviors, including decreased body bending and head thrashing frequencies, were observed in C. elegans that were fed E. coli pre-treated with ZnO-NPs, which might have occurred because of damage to the D-type GABAergic motor neurons. However, these toxic effects were not apparent in C. elegans that were fed E. coli pre-treated with zinc chloride (ZnCl2). Therefore, ZnO-NPs particulates, rather than released Zn ions, damage the D-type GABAergic motor neurons and adversely affect the locomotive behaviors of C. elegans via dietary transfer.
Repurposing Antidepressants and Phenothiazine Antipsychotics as Efflux Pump Inhibitors in Cancer and Infectious Diseases

Multidrug resistance (MDR) is a major obstacle in the therapy of infectious diseases and cancer. One of the major mechanisms of MDR is the overexpression of efflux pumps (EPs) that are responsible for extruding antimicrobial and anticancer agents. EPs have additional roles of detoxification that may aid the development of bacterial infection and the progression of cancer. Therefore, targeting EPs may be an attractive strategy to treat bacterial infections and cancer. The development and discovery of a new drug require a long timeline and may come with high development costs. A potential alternative to reduce the time and costs of drug development is to repurpose already existing drugs. Antidepressants and antipsychotic agents are widely used in clinical practice in the treatment of psychiatric disorders and some somatic diseases. Antidepressants and antipsychotics have demonstrated various beneficial activities that may be utilized in the treatment of infections and cancer. This review aims to provide a brief overview of antibacterial and anticancer effects of selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs) and phenothiazine antipsychotics, while focusing on EPs. However, it should be noted that the antimicrobial activity of a traditionally non-antibiotic drug may have clinical implications regarding dysbiosis and bacterial MDR.
Novel biodegradable composites and foams of polylactide and chitin

This study details the fabrication and foaming of biodegradable polylactide (PLA) and chitin composites. Three types of chitin were examined; as-received, chitin nano-whiskers and chitin nano-whiskers with a compatibilizing agent. The chitin and chitin composite morphology was characterized with transmission and scanning electron microscopy, respectively. The thermal, rheological and mechanical behavior of the PLA-chitin composites was investigated. It was found that Chitin decreases the thermal and rheological stability of the composites. The stiffness of the composites was found to increase with increasing chitin content while the strength was found to decrease as a result of PLA hydrolysis. Biodegradable foams of PLA-chitin composites were produced and the expansion behavior was correlated with the visco-elastic observations. The statistical significance of chitin type and composition dependence on the mechanical properties and foam morphologies were evaluated.
A Heteroscedastic Generalized Extreme Value Discrete Choice Model

Of the commonly used discrete choice models, the probit class allows flexible covariance structures for disturbances but is computationally burdensome for problems with more than a few alternatives. The generalized extreme value (GEV) class, including the widely used logit and nested logit models, has the advantage of computational ease but suffers in general from the restriction of homoscedastic disturbances. This article generalizes the GEV class to allow heteroscedastic disturbances across decision makers as well as across choice alternatives. The resulting models include the heteroscedastic extreme value model as a special case, which is a generalized logit model with heteroscedasticity across choice alternatives. Particular attention is paid to the heteroscedastic logit and nested logit models because of their widespread use in practice. An empirical application reanalyzing data from the 1980 presidential election tests the hypothesis of information-induced heteroscedasticity across voters and finds support for a heteroscedastic logit model that reveals stronger effects of voter information on the turnout decision than suggested by the original standard logit model in Ordeshook and Zeng.
Detailed Analysis of Composited Digital Radar and Satellite Data

Abstract A technique is developed to digitally composite satellite and radar imagery in a common coordinate reference frame. Results obtained from using Geosynchronous Operational Environmental Satellite (GOES) visible and infrared data, 5 cm radar data, and recording raingage data are presented. The composite displays are created on Colorado State University's All Digital Video Imaging System for Atmospheric Research (ADVISAR), an interactive image processing system that uses modern high fidelity digital video display technology. An efficient methodology based on analytic transforms for remapping dissimilar digital image formats into common map projections is discussed. Applications of multi-sensor composite images are demonstrated with the use of two case studies. The technique is shown to enhance our understanding of a) convective development, b) organization of mesoscale features as they relate to the synoptic scale, c) severe storm development, and d) precipitation mechanisms. Our final comments conc.
Nanovesicles as Vanillin Carriers for Antimicrobial Applications

Vanillin is a natural compound easily extracted from plants. It has neuroprotective, anti-carcinogenic, antioxidant, antimicrobial, and anti-biofilm properties. It also presents high volatility, high hydrophilicity, and low bioavailability. Nanomaterials can be used to improve pharmacodynamics, solubility, and stability and to enhance pharmacokinetics. In this work, non-ionic surfactant vesicles were synthesized as vanillin carriers: neutral niosomes formed by Span60 and cholesterol, positive charged niosomes formulated with cetyltrimethylammonium bromide (CTAB), and negatively charged niosomes formulated with sodium dodecyl sulfate (SDS). Niosomes synthesis was carried out with two commonly used methods: thin film hydration (TFH) and ethanol injection method (EIM). The niosomes synthesized were used to prepare two different materials: (i) a powder containing the lyophilized noisome with vanillin systems and (ii) a gelatin matrix film containing niosomes with vanillin. Lyophilization was carried out using maltodextrin as a cryoprotectant. The lyophilization of colloidal structures allows for storage at room temperature for long periods of time, keeping their organoleptic characteristics invariable. Niosomes were characterized before and after the lyophilization process in terms of morphological characterization, size, polydispersity index (PDI), and zeta potential. Moreover, niosomes cargo was evaluated by calculating the encapsulation efficiency (EE) and loading capacity (LC). Results showed that the use of the TFH method allowed us to obtain niosomes of 255 nm with high EE (up to 40%) and LC values higher than EIM. The lyophilization process decreased the LC of the vesicles prepared, but this decrease was mitigated by up to 20% when ionic surfactants were used on the membrane bilayer. Gelatin films are biodegradable materials suitable for food packing applications. The incorporation of a natural compound with antimicrobial activity would be a clear advantage for such an application. The films prepared were characterized in terms of morphology, water solubility, color, and transparency. Niosomes synthesized by thin film hydration had better chemical and physical properties to load vanillin. Especially in the case of application in films, niosomes with a negative charge, formed by SDS, and vanillin loaded gave better mechanical and chemical characteristics to the film.
Interventions for the Prevention of Oral Mucositis in Patients Receiving Cancer Treatment: Evidence from Randomised Controlled Trials

Oral mucositis is a common and most debilitating complication associated with cancer therapy. Despite the significant clinical and economic impact of this condition, there is little to offer to patients with oral mucositis, and the medications used in its management are generally only palliative. Given that mucositis is ultimately a predictable and, therefore, potentially preventable condition, in this study we appraised the scientific literature to evaluate effective methods of prevention that have been tested in randomised controlled trials (RCTs). Published high-level evidence shows that multiple preventative methods are potentially effective in the prevention of oral mucositis induced by radiotherapy, chemotherapy, or both. Anti-inflammatory medications (including benzydamine), growth factors and cytokines (including palifermin), cryotherapy, laser-and-light therapy, herbal medicines and supplements, and mucoprotective agents (including oral pilocarpine) showed some degree of efficacy in preventing/reducing the severity of mucositis with most anticancer treatments. Allopurinol was potentially effective in the prevention of radiotherapy-induced oral mucositis; antimicrobial mouthwash and erythropoietin mouthwash were associated with a lower risk of development of severe oral mucositis induced by chemotherapy. The results of our review may assist in highlighting the efficacy and testing the effectiveness of low-cost, safe preventative measures for oral mucositis in cancer patients.
Reconfigurable photonic integrated transmitter for metro-access networks

A reconfigurable photonic integrated transmitter, enabling dynamic resource allocation in the metro-access network, is proposed. The device consists of a multicarrier sliceable bandwidth variable transmitter (MC-SBVT) realized in indium phosphide and a silicon-nitride-based optical cross-connect (OXC). The proposed architecture delivers full flexibility in terms of the choice of data format/bandwidth, channel spacing, and wavelength assignment. The functional design of the MC-SBVT and OXC as well as their practical realization are discussed. Preliminary characterization results of the photonic-integrated-circuit-based MC-SBVT, demonstrating the reconfigurability of the device, are also presented.
Estimated performance of an adaptive trailing-edge device aimed at reducing fuel consumption on a medium-size aircraft

This paper deals with the estimation of the performance of a medium-size aircraft (3-hour flight range) equipped with an adaptive trailing edge device (ATED) that runs span-wise from the wing root in the flap zone and extends chord-wise for a limited percentage of the MAC. Computations are calculated referring to the full wing and do not refer to the complete aircraft configuration. Aerodynamic computations, taking into account ideal shapes, have been performed by using both Euler and Navier- Stokes method in order to extract the wing polars for the reference and the optimal wing, implementing an ATED, deflected upwards and downwards. A comparison of the achieved results is discussed. Considering the shape domain, a suitable interpolation procedure has been set up to obtain the wing polar envelop of the adaptive wing, intended as the set of “best” values, picked by each different polar. At the end, the performances of the complete reference and adaptive wing are computed and compared for a symmetric, centered, leveled and steady cruise flight for a medium size aircraft. A significant fuel burn reduction estimate or, alternatively, an increased range capability is demonstrated, with margins of further improvements. The research leading to these results has gratefully received funding from the European Union Seventh Framework Programme (FP7/2007- 2013) under Grant Agreement n° 284562.
Proper scaling of the anomalous Hall effect in the Co/Pt multilayers

In the spin-valve Co(4 A)/Pt(36 A)/[Co(4A)/Pt(6 A)]n multilayers with perpendicular anisotropy, an oscillatory variation of the anomalous Hall resistivity and longitudinal resistivity has been observed with the increase in the repetition number n, and it is almost temperature-independent. The anomalous Hall resistivity is fitted by a new scaling which includes the residual resistivity, i.e., ρAH=a'ρxx0+bρxx2. a′changes nonmonotonically with the repetition number n, while b oscillates as a function of n. These observed oscillatory behaviors of ρxx, b, and ρAH can be mainly attributed to the Co/Pt interface scattering.In the spin-valve Co(4 A)/Pt(36 A)/[Co(4A)/Pt(6 A)]n multilayers with perpendicular anisotropy, an oscillatory variation of the anomalous Hall resistivity and longitudinal resistivity has been observed with the increase in the repetition number n, and it is almost temperature-independent.

Effect of hydrostatic pressure on the photocurrent density of InGaN = GaN multiple quantum well solar cells

: In this paper, a numerical model is used to analyze photovoltaic parameters according to the electronic properties of InGaN/GaN multiple quantum-well solar cells (MQWSC) under hydrostatic pressure. Finite-difference methods are used to acquire energy eigenvalues, and their corresponding eigenfunctions of InGaN/GaN MQWLED and the hole eigenstates are calculated via a 6 (cid:2) 6 k.p method under applied hydrostatic pressure. All symmetry-allowed transitions up to the ﬁfth subband of the quantum wells (multi-subband model) and barrier optical absorption are considered. Further, the linewidth due to the carrier-carrier and carrier-longitudinal optical (LO) phonon scattering is considered. The result of the photoelectric current is compared with the single-subband model. According to the results, a change in pressure up to 10 GPa increases the intraband scattering time up to 38 fs for heavy holes and 40 fs for light holes, raises the height of the Lorentz function, reduces the excitonic binding energy, and decreases the photocurrent density up to 5mA = cm 2 . The multi-subband model positively affects the photocurrent density, increasing it by 4mA = cm 2 , contrary to the pressure function.
Role of IT & analytics on business performance

The growth of big data has activated overwhelming investments in company analytics fixes, but large scale and dependable empirical proof about the company worth of big data and analytics stays limited. This particular paper provides the end result of an econometric analysis which analyzes the guidance, sign, and magnitude of the connection between firm performance and BDA based on independent dimensions of BDA assets. With a distinctive panel data set which includes comprehensive info regarding BDA treatments run by 814 organizations throughout the timeframe from 2008 to 2014, on one hand, and the financial performance of theirs, on the opposite hand, we calculate the connection between BDA assets and firm efficiency and realize that fresh BDA property are connected with an average of three to seven % improvement in solid efficiency. Nevertheless, we additionally discover substantial disparities in earnings from BDA whenever we think about the market where a firm operates: While firms in IT intensive or maybe very competitive industries are obviously in a position to acquire value from BDA assets, we didn't identify measurable efficiency advancement for firms outdoors these business organizations. Taken collectively, our findings offer strong empirical evidence for the company worth of BDA, but additionally highlight crucial boundary problems.

Quasitriangular Hopf Algebras and Yang-Baxter Equations

This is an informal introduction to the theory of quasitriangular Hopf algebras and its connections with physics. Basic properties and applications of Hopf algebras and Yang-Baxter equations are reviewed, with the quantum group Uq(sl2) as a frequent example. The development builds up to the representation theory of quasitriangular Hopf algebras. Much of the abstract representation theory is new, including a formula for the rank of a representation.
A generalization of Levi-Civita’s parallelism and the Frenet formulas

where the coefficients gap are functions of xl, • • •, xn only, and where the notation implies that « and ß are summed from 1 to n. The vector analysis of such a geometry has been rather systematically developed.t Levi-Civita has developed a theory of parallelism^ for the Riemann space, in which a vector £ defined at each point of a curve is said to remain parallel to itself as it moves along the curve if it satisfies the system of equations
Reconstruction formula for the potential function of Sturm–Liouville problem with eigenparameter boundary condition

It is known that the uniqueness of potential function of the Sturm–Liouville problem can be shown from the nodal points. In this article, we solve the inverse nodal problem of the reconstruction of the potential function q from the nodal data by a pointwise limit. We show that this convergence is in the L1. It is mentioned that this method is based on the works of Law and Yang, but we have applied the method for the Sturm–Liouville problem depending on eigenparameter boundary conditions.
Migration and deposition of 13C in the full-tungsten ASDEX Upgrade tokamak

The migration of carbon in low-density, low-confinement plasmas of ASDEX Upgrade was studied by injecting 13C into the main chamber of the torus at the end of the 2007 experimental campaign. A selection of standard tungsten-coated lower-divertor and main-chamber tiles as well as a complete set of lower-divertor tiles with an uncoated poloidal marker stripe were removed from one poloidal cross section and analysed using secondary ion mass spectrometry. The poloidal deposition profiles of 13C on both the tungsten-coated tiles and on the uncoated graphite areas of the marker tiles were measured and compared. For the W-coated lower-divertor tiles, 13C was deposited mainly on the high-field side tiles, while barely detectable amounts of 13C were observed on low-field side samples. In contrast, on the uncoated marker stripes the deposition was equally pronounced in the high-field and low-field side divertor. The marker-tile results are in agreement with those obtained from graphite tiles after the 2003 and 2005 13C experiments in ASDEX Upgrade. In the case of W-coated tiles, the 13C measurements were complemented by determining the total amount of deposited carbon (12C) on the tiles, which also shows strong deposition at the inner parts of the lower divertor. The estimated deposition of 13C on W at the divertor areas was less than 1.5% of the injected amount of 13C atoms. The 13C analyses of the main-chamber tiles and small silicon samples mounted in remote areas revealed significant deposition in the upper divertor, in upper parts of the heat shield, in the limiter region close to the injection valve, and below the roof baffle. Approximately 8% of the injected 13C is estimated to have accumulated in these regions. Possible reasons for the different deposition patterns on W and on graphite in different regions of the torus are discussed.
Void formation and surface energies in Cu(InGa)Se2

The spontaneous formation of voids has been observed in Cu(In,Ga)Se2 films deposited by multistage evaporation processes but was not found commonly in single-stage evaporated material. These voids may be isolated in the grains or may occur at the grain boundaries. The voids exhibit strongly faceted geometries with interior surfaces being close-packed {112} planes of the chalcopyrite structure. A model based on the Kirkendal effect [Trans. AIME 171, 130 (1947)] and the interdiffusion and phase reaction in the bilayer process is proposed to explain the observation. The void shape is analyzed and an approximate Wulff construction [Z. Kristallogr. Mineral. 34, 449 (1901)] is used to estimate the relative surface energies of the predominant facets. Certain dislocation cores are also found to be unstable and convert to nanovoids in the presence of sufficient atomic vacancies moving in the lattice.
Decomposing the Non-Gaussian Surface in Sum of Gaussian Surfaces

The decomposition of the multivariate Non-Gaussian PDF in the sum of a Gaussian PDF instead of the Gram-Charlier series is investigated. Four parameters need to be found by minimizing the integrated square of the difference between Cox-Munk function and its approximation. The backscattering radar cross section (RCS) of the surface is calculated by the Kirchhoff approximation (KA) under different value of k using the formula of decomposition of the Non-Gaussian. The condition of KA satisfying electromagnetic scattering scale from Gaussian and Non-Gaussian surfaces is taken into account by computing the backscattering coefficients in HH and VV polarity.
On the Robustness of Combined Tests for Trends in Proportions

Abstract Several models with monotone trend in proportions are considered for 2 × I × J contingency tables. For one stratum (I = 1) and broad regularity conditions, the C(α) test statistic for testing for trend is shown to be fully efficient for all choices of the model with monotone trend. For several strata, the efficiency of each C(α) test is compared with the efficiency of the C(α) test appropriate when each of the other models holds. These relative efficiencies are used for choosing the most robust tests in a variety of sampling situations.
