Influence of core property on multi-electron process in slow collisions of isocharged sequence ions with neon

Influence of core property on multi-electron process in the collisions of q = 6-9 and 11 isocharged sequence ions with Ne is investigated in the keV/u region. The cross-section ratios of double-, triple-, quadruple- and total multielectron processes to the single electron capture process as well as the partial ratios of different reaction channels to the relevant multi-electron process are measured by using position-sensitive and time-of-flight techniques. The experimental data are compared with the theoretical predictions including the extended classical over-barrier model, the molecular Columbic barrier model and the semi-empirical scaling law. Results show a core effect on multi-electron process of isocharge ions colliding with Neon, which is consistent with the results of Helium we obtained previously
Compact and tunable mid-infrared source based on a 2 μm dual-wavelength KTiOPO4 intracavity optical parametric oscillator

Using a double resonant KTiOPO4 (KTP) intracavity optical parametric oscillator operating at degenerated point of 2 μm, we demonstrate a unique mid-infrared source based on difference frequency generation in GaSe crystal. The output tuning range is 8.42-19.52 μm, and a peak power of 834 W for type-I phase matching scheme and 730 W for type-II phase matching scheme are achieved. Experimental results show that this oscillator is a good alternative to the generator of a compact and tabletop mid-infrared radiation with a widely tunable range
Nonlinear analysis of traffic jams in an anisotropic continuum model

This paper presents our study of the nonlinear stability of a new anisotropic continuum traffic flow model in which the dimensionless parameter or anisotropic factor controls the non-isotropic character and diffusive influence. In order to establish traffic flow stability criterion or to know the critical parameters that lead, on one hand, to a stable response to perturbations or disturbances or, on the other hand, to an unstable response and therefore to a possible congestion, a nonlinear stability criterion is derived by using a wavefront expansion technique. The stability criterion is illustrated by numerical results using the finite difference method for two different values of anisotropic parameter. It is also been observed that the newly derived stability results are consistent with previously reported results obtained using approximate linearisation methods. Moreover, the stability criterion derived in this paper can provide more refined information from the perspective of the capability to reproduce nonlinear traffic flow behaviors observed in real traffic than previously established methodologies
Thermal entanglement in molecular spin rings

The thermal entanglement in the triangular molecular spin ring with Dzyaloshinskii-Moriya interaction is studied. The concurrences of arbitrary two spins of the triangular molecular spin ring for various cases are evaluated. The tendency of the concurrence with Dzyaloshinskii-Moriya interaction and temperature is analysed and discussed. We note that the concurrence arrives at its maximum in the regime with the large Dzyaloshinskii-Moriya interaction and low temperature, and gradually decreases to zero with the increase of temperature. The concurrence has different features for the ferromagnetic and antiferromagnetic cases. For completeness, we also numerically calculate the concurrence of spin rings with N > 3 spins and analyse their behaviours
Massive particle radiation from Gibbons-Maeda black hole

This paper investigated the massive particle radiation from Gibbons-Maeda black hole by using a semi-classical method. The calculations showed that, if the self-gravitation of the radiated particle is taken into account, the radiation spectrum deviates from exact black body spectrum and the rate of tunneling equals precisely the exponent of the difference of the black hole entropies before and after emission. The conclusion supports the viewpoint of information conservation
Antiviral Activity of the Effective Monomers from Folium Isatidis Against Influenza Virus in Vivo

In order to evaluate the anti-influenza virus activity of the effective monomer from Folium Isatidis (FI) in vivo, we established mice model with viral pneumonia and divided them into 3 different dose groups, then observed their lung indexes, pulmonary pathological changes, pulmonary virus hemagglitination titers, living time and death rates. The results showed that the monomer could reduce the pulmonary index from 2.64 to 1.93, 1.63 and 1.40 (P<0.01) and decrease the hemagglitination titer from 1.15 to 0.84, 0.70 and 0.59 (P<0.01). In addition, different groups of FI could significantly lessen the mortality rate from 100% to 30%, 25% and 15%, and prolong the living time from 5.Id to 6.5d, 8.4d and 8.9d respectively(P<0.01). The high dose (75 mg/kg'd) has the similar effect with 100 mg/kg/d dose of virazole(P>0.05), and more effective than 200 mg/kg/ddose of antiviral liquor (p<0.05)
Chemical composition and antioxidant activity of certain Morus species

In the present work,the fruits of four Morus species,namely Morus alba(white mulberry),Morus nigra (black mulberry),Morus laevigata(large white fruit),and Morus laevigata(large black fruit),were analyzed for proximate composition,essential minerals,and antioxidant potentials.For this purpose,the ripe fruits were collected from the northern regions of Pakistan.The major nutritional components(moisture,ash,lipids,proteins,fibres,carbohydrates,and total sugar)were found to be in the suitable range along with good computed energy.Total dry weight, pH,and titratable acidity(percent citric acid)were(17.60±1.94)-(21.97±2.34)mg/100 g,(3.20±0.07)-(4.78±0.15),and (0.84±0.40)%-(2.00±0.08)%,respectively.Low riboflavin(vitamin B2)and niacin(vitamin B3)contents were recorded in all the fruits,while ascorbic acid(vitamin C)was in the range from(15.20±1.25)to(17.03±1.71)mg/100 g fresh weight(FW).The mulberry fruits were rich with regard to the total phenol and alkaloid contents,having values of (880±7.20)-(1650±12.25)mg/100 g FW and(390±3.22)-(660±5.25)mg/100 g FW,respectively.Sufficient quantities of essential macro-(K,Ca,Mg,and Na)and micro-(Fe,Zn,and Ni)elements were found in all the fruits.K was the predominant element with concentration ranging from(1270±9.36)to(1731±11.50)mg/100 g,while Ca,Na,and Mg contents were(440±3.21)-(576±7.37),(260±3.86)-(280±3.50),and(240±3.51)-(360±4.20)mg/100 g,respectivly. The decreasing order of micro-minerals was Fe>Zn>Ni.The radical scavenging activity of methanolic extract of fruits was concentration-dependent and showed a correlation with total phenolic constituents of the respective fruits.Based on the results obtained,mulberry fruits were found to serve as a potential source of food diet and natural antioxidants
Case Report: Pure word deafness associated with extrapontine myelinolysis

Extrapontine myelinolysis and pure word deafness are very uncommon disorders.Here,we report a case of a 19-year-old woman who suffered from osmotic demyelination syndrome with coincidence of typical pure word deafness.As a consequence of rapid correction of hyponatremia,the patient demonstrated an initial onset of cortical deafness,and then progressed to generalized auditory agnosia,which eventually developed into confined verbal auditory agnosia(pure word deafness).Bilateral extrapontine myelinolysis was confirmed using brain magnetic resonance imaging.This case suggests that verbal and nonverbal stimuli may involve separate thalamocortical pathways
Mechanical Characteristics of Typical Plant Leaves

Plant leaf is a natural composite biomaterial, and its strength is closely related to the microstructure. In this paper, the mechanical characteristics of eight species of plant leaves were investigated and analyzed. The ultimate strength of leaves and the hardness of leaf surfaces were measured by using universal testing machine and nanoindenter tester, respectively. The tensile strength of the parallel microstructure was investigated based on its cross-sectional mechanical model. The results of tension tests indicate that the ultimate strength of a leaf is related to the material composition and structure. The coriaceous leaves usually exhibit higher tensile strength. For example, the Phyllostachys pubescens leaf can achieve the maximum ultimate strength of 5.9091 N·mm~(-2). It is concluded from the results of hardness tests that material components of leaf surface can influence the surface hardness evidently. The leaf surface composed of more lignin and cellulose materials shows a higher surface hardness than that composed of more carbohydrates materials
Finite Element Analysis of the Contact Mechanics of Ceramic-on-Ceramic Hip Resurfacing Prostheses

Ceramics are good alternative to metal as bearing couple materials because of their better wear resistance. A Finite Element (FE) study was performed to investigate the contact mechanics and stress distribution of Ceramic-on-Ceramic (COC) hip resurfacing prostheses. It was focused in particular on a parametric study to examine the effects of radial clearance, loading, alumina coating on the implants, bone quality, and fixation of cup-bone interface. It was found that a reduction in the radial clearance had the most significant effect on the predicted contact pressure distribution among all of the parameters considered in this study. It was determined that there was a significant influence of non-metallic materials, such as the bone underneath the bearing components, on the predicted contact mechanics. Stress shielding within the bone tissue was found to be a major concern when regarding the use of ceramic as an alternative to metallic resurfacing prostheses. Therefore, using alumina implants with a metal backing was found to be the best design for ceramic resurfacing prostheses in this study. The loading, bone quality, and acetabular cup fixation conditions were found to have only minor effects on the predicted contact pressure distribution along the bearing surfaces
Enhanced Compliant Adhesive Design and Fabrication with Dual-Level Hierarchical Structure

Synthetic dry adhesives inspired by the nano- and micro-scale hairs found on the feet of geckos and some spiders have been developed for almost a decade. Elastomeric single level micro-scale mushroom shaped fibres are currently able to function even better than natural dry adhesives on smooth surfaces under normal loading. However, the adhesion of these single level synthetic dry adhesives on rough surfaces is still not optimal because of the reduced contact surface area. In nature, contact area is maximized by hierarchically structuring different scales of fibres capable of conforming surface roughness. In this paper, we adapt the nature's solution arid propose a novel dual-level hierarchical adhesive design using Polydimethylsiloxane (PDMS), which is tested under peel loading at different orientations. A negative macro-scale mold is manufactured by using a laser cutter to define holes in a Poly(methyl methacrylate) (PMMA) plate. After casting PDMS macro-scale fibres by using the obtained PMMA mold, a previously prepared micro-fibre adhesive is bonded to the macro-scale fibre substrate. Once the bonding polymer is cured, the micro-fibre adhesive is cut to form macro scale mushroom caps. Each macro-fibre of the resulting hierarchical adhesive is able to conform to loads applied in different directions. The dual-level structure enhances the peel strength on smooth surfaces compared to a single-level dry adhesive, but also weakens the shear strength of the adhesive for a given area in contact. The adhesive appears to be very performance sensitive to the specific size of the fibre tips, and experiments indicate that designing hierarchical structures is not as simple as placing multiple scales of fibres on top of one another, but can require significant design optimization to enhance the contact mechanics and adhesion strength
Bichromatic laser frequency stabilization with Doppler effect and polarization spectroscopy

The interaction between polychromatic fields and atoms is an important subject in quantum optics. Frequency locking for small frequency interval multi-field is usually required in some experiments. In this letter, we experimentally demonstrate a holistic scheme for bichromatic laser frequency stabilization. Compared with traditional saturation absorption methods and complicated frequency shift schemes, offset locking for bichromatic fields is simply achieved using polarization spectroscopy and Doppler effect. Frequency locking with a wide-range asymmetry of the detuning is also shown. Our scheme makes laser spectroscopy experiments with polychromatic fields more convenient
Fluorescence molecular tomography system for in vivo tumor imaging in small animals

A fluorescence molecular tomography system for in vivo tumor imaging is developed using a 748-nm continuous wave diode laser as an excitation source. A high sensitivity cooled charge-coupled device (CCD) camera with excitation and emission filters is utilized to obtain the excitation and fluorescence images. The laser beam performs fast raster scanning using a dual-axis galvanometric scanner. The accuracy of the laser spot position at the source window is within ±200 μm. Based on the phantom experimental results, the spatial resolution is less than 1.7 mm, and the relative quantitation error is about 10%. In vivo imaging of a tumor-bearing nude mouse tagged with near-infrared dye demonstrates the feasibility of the system
A New Sequential Systems of Linear Equations Algorithm of Feasible Descent for Inequality Constrained Optimization

Based on a new efficient identification technique of active constraints introduced in this paper, a new sequential systems of linear equations (SSLE) algorithm generating feasible iterates is proposed for solving nonlinear optimization problems with inequality constraints. In this paper, we introduce a new technique for constructing the system of linear equations, which recurs to a perturbation for the gradients of the constraint functions. At each iteration of the new algorithm, a feasible descent direction is obtained by solving only one system of linear equations without doing convex combination. To ensure the global convergence and avoid the Maratos effect, the algorithm needs to solve two additional reduced systems of linear equations with the same coefficient matrix after finite iterations. The proposed algorithm is proved to be globally and superlinearly convergent under some mild conditions. What distinguishes this algorithm from the previous feasible SSLE algorithms is that an improving direction is obtained easily and the computation cost of generating a new iterate is reduced. Finally, a preliminary implementation has been tested
Super d-antimagic Labelings of Disconnected Plane Graphs

This paper deals with the problem of labeling the vertices, edges and faces of a plane graph in such a way that the label of a face and the labels of the vertices and edges surrounding that face add up to a weight of that face, and the weights of all s-sided faces constitute an arithmetic progression of difference d, for each s that appears in the graph. The paper examines the existence of such labelings for disjoint union of plane graphs
THE DATA ENVELOPMENT ANALYSIS MODEL WITH INTERSECTION FORM PRODUCTION POSSIBILITY SET

The data envelopment analysis (DEA) model is used to evaluate the relative economic efficiency of a given set of decision making units (DMUs). In this paper, the DEA production possibility set is transferred from the conventional sum form into the intersection form which is represented by a linear inequality system. Although it is time consuming to obtain the intersection form of the production possibility set, it suggests a new angle to investigate the properties of DMUs and to extend the DEA research further beyond the efficiency measurement. Following the intersection form, the analytical formula of the efficiency indicator and projection is given. Various aspects of technical efficiency, returns to scale and evidence of congestion of the DMUs are studied. The relationship between the weak DEA efficiency and the weak Pareto solution is discussed. Finally, a procedure for DMU grouping is proposed to help the decision makers for better resource reallocation and strategy adjustment

Kinetics and product distribution studies on ruthenium-promoted cobalt/alumina Fischer-Tropsch synthesis catalyst

Hydrocarbon production rates and distributions on ruthenium promoted alumina supported cobalt Fischer-Tropsch synthesis(FTS)catalyst were studied by the concept of two superimposed Anderson-Schulz-Flory(ASF)distributions.The results indicated that the characterizing growth probabilitiesα1 andα2 were strongly dependent on reaction conditions.By increasing the H2/CO partial pressure ratios and reaction temperatures,deviation from normal ASF distribution decreases and the double-α-ASF distribution changes into a straight line.Based on the concept of double-α-ASF distribution,a useful rate equation for the production of hydrocarbons under industrial reaction conditions is obtained
Methane aromatization in the absence of oxygen over extruded and molded MoO3/ZSM-5 catalysts:Influences of binder and molding method

The influences of binder and molding method on the catalytic performance of methane aromatization in the absence of O2 over MoO3/ZSM-5 catalysts were investigated.SEM,NH3-TPD,FT-IR of adsorbed pyridine,N2 adsorption-desorption,cyclohexane adsorption and XPS were employed to characterize the physical and chemical properties of the catalysts.It was found that SiO_2 was a suitable binder for the catalyst due to its appropriate weak acidity.The laminar catalyst comprising of an inert spherical core and a MoO_3/ZSM-5 laminar shell with 0.1-0.2 mm in thickness showed a better catalytic performance than the extruded catalyst.The improved activity of the laminar catalyst could be attributed to the easy carbonization of Mo species and the quick removal of reaction products from the catalyst surface
Oxidation of propane to acrylic acid and acetic acid over alkaline earth-doped Mo-V-Sb-Ox catalysts

Alkaline earth metal(Mg,Ca,Sr and Ba)-doped Mo-V-Sb-Ox catalysts,prepared by a dry-up method,have been investigated for their catalytic performance in the oxidation of propane under different reaction conditions.The catalysts have been characterized by N2 adsorption-desorption, temperature-programmed desorption(TPD)of NH3,SEM and XRD.Influence of water vapor on the catalytic performance,particularly on the selectivities to acetic acid and acrylic acid,has also been studied.The selectivity to acrylic acid was improved significantly by the doping of alkaline earth metals to Mo-V-Sb-Ox catalysts.The surface acidic sites of the catalyst decreased with the doping of the catalyst with alkaline earth metals,which ultimately was found to be beneficial for obtaining high selectivity to acrylic acid.The catalytic activity and product selectivities were found to be influenced by the reaction temperature,C_3H_8/O_2 ratio and space velocity.A significant improvement in the selectivity to acrylic acid has also been observed by the addition of water vapor in the feed of propane and oxygen in the oxidation of propane
Driving Factors for Forest Fire Occurrence in Durango State of Mexico:A Geospatial Perspective

Forest fire is one of the major causes of forest loss and therefore one of the main constraints for sustainable forest management worldwide.Identifying the driving factors and understanding the contribution of each factor are essential for the management of forest fire occurrence.The objective of this study is to identify variables that are spatially related to the occurrence and incidence of the forest fire in the State of Durango,Mexico.For this purpose, data from forest fire records for a five-year period were analyzed.The spatial correlations between forest fire occurrence and intensity of land use,susceptibility of vegetation,temperature,precipitation and slope were tested by Geographically Weighted Regression(GWR)method,under an Ordinary Least Square estimator.Results show that the spatial pattern of the forest fire in the study area is closely correlated with the intensity of land use,and land use change is one of the main explanatory variables.In addition,vegetation type and precipitation are also the main driving factors.The fitting model indicates obvious link between the variables.Forest fire was found to be the consequence of a particular combination of the environmental factors,and when these factors coexist with human activities,there is high probability of forest fire occurrence.Mandatory regulation of human activities is a key strategy for forest fire prevention
Grain-size Characteristics of Sediment in Daniugou Peatland in Changbai Mountains,Northeast China: Implications for Atmospheric Dust Deposition

The grain-size distribution characteristics and grain-size parameters of sediment in two vertical sections of Daniugou peatland in the Changbai Mountains were systematically investigated.A comparative analysis of the sediment granularity using a discriminative function with Hongyuan peat,red clay,loess-paleosol,fluvial deposit as well as lacustrine deposit was also conducted.It turns out that the vertical section of Daniugou peat ash is primarily constituted by clay and silt particles,and the content of sand is relatively small.Grain-size frequency curves generally show a single-peak modality while a bimodal pattern is detected in the upper layer.The grain-size component and peak pattern of grain-size frequency curves also illustrate that peat ash materials were transported to the peatland by long-range aeolian dust during the deposition process,while there existed short-distance dust influence in peat deposition of the upper layer.Comparisons of grain-size parameters and the discriminative Y-value of Daniugou peat ash with those of typical aeolian sediments show close similarities,suggesting the possibility that atmospheric dust transport processes were involved in the accumulation of peat again.Moreover,the variations of grain-size distribution suggest the local environmental deterioration which is just the driving force of local dust elevation.Grain-size analysis of peatland sediment is demonstrated to be one effective method to extract information about regional and global environmental evolution,and more attention should be paid to current local ecological environment and to seeking a balance between economic development and environmental protection in Northeast China
A novel polyaniline/mesoporous carbon nano-composite electrode for asymmetric supercapacitor

A novel nano-composite of polyaniline/mesoporous carbon (PANI/CMK-3) was prepared with mesoporous carbon (CMK-3) serving as the support. Electrochemical asymmetric capacitors have been successfully designed by using PANI/CMK-3 composite and CMK-3 as positive and negative electrode, respectively. The results showed that the discharge capacity of the asymmetric capacitor could reach 87.4 F/g under the current density of 5 mA/cm2 and cell voltage of 1.4 V. The energy density of the asymmetric capacitor was up to 23.8 Wh/kg with a power density of 206 W/kg. Furthermore, PANI/CMK-3-CMK-3 asymmetric capacitor using this PANI/CMK-3 nano-composite could be activated quickly and possess high charge-discharge efficiency
