Properties of a family of merit functions and a merit function method for the NCP

A family of merit functions are proposed, which are the generalization of several existing merit functions. A number of favorable properties of the proposed merit functions are established. By using these properties, a merit function method for solving nonlinear complementarity problem is investigated, and the global convergence of the proposed algorithm is proved under some standard assumptions. Some preliminary numerical results are given.

Merits and Demerits of Food Additives

Food additive is a double-edged sword. It has merits and demerits. Food additives have such merits as improving sensory properties of foods,preventing deterioration and extending the shelf life,increasing varieties of foods,enhancing convenience of foods,facilitating food processing,and satisfying other demands. However,excessive and illegal use of food additives will exert adverse influence on food security.Therefore,it is required to take proper measures to bring merits of food additives into full play,and get rid of their demerits.

A high figure of merit localized surface plasmon sensor based on a gold nanograting on the top of a gold planar film

We investigate the sensitivity and figure of merit （FOM） of a localized surface plasmon （LSP） sensor with gold nanograting on the top of planar metallic film. The sensitivity of the localized surface plasmon sensor is 317 nm/RIU, and the FOM is predicted to be above 8, which is very high for a localized surface plasmon sensor. By employing the rigorous coupled-wave analysis （RCWA） method, we analyze the distribution of the magnetic field and find that the sensing property of our proposed system is attributed to the interactions between the localized surface plasmon around the gold nanostrips and the surface plasmon polarition on the surface of the gold planar metallic film. These findings are important for developing high FOM localized surface plasmon sensors.

Figure of Merit Analysis of a Hybrid Solar-geothermal Power Plant

Figure of merit analysis is a general methodology used to evaluate whether a hybrid power plant could produce more power than two stand-alone power plants. In this paper, the assessment methodology using figure of merit analysis was re-examined for a hybrid solar-geothermal power plant. A new definition of the figure of merit was introduced specifically for a solar boosted geothermal plant to include both the technical and economic factors. The new definition was then applied in a case study of a hypothetical demonstration hybrid solar-geothermal power plant in Australia. The power plant was considered to have a typical net power output of 2.2 MW with a solar energy fraction of 27%. The analysis was performed to compare the power output and capital cost of the hybrid plant with the state-of-the-art (SoA) and existing stand-alone solar and geothermal plants. Based on the new definition, the hybrid plant was found to generally outperform the two existing stand-alone plants. Moreover, at an ambient temperature of 5 °C, the hybrid plant was found to outperform the SoA stand-alone plants when the geothermal temperature was greater than 150 °C. For geothermal temperature of 180 °C on the other hand, the hybrid plant outperformed the SoA stand-alone plants at ambient temperatures lower than 33 °C.

Merit functions for nonsmooth complementarity problems and related descent algorithm

Under some assumptions, the solution set of a nonlinear complementarity problem coincides with the set of local minima of the corresponding minimization problem. This paper uses a family of new merit functions to deal with nonlinear complementarity problem where the underlying function is assumed to be a continuous but not necessarily locally Lipschitzian map and gives a descent algorithm for solving the nonsmooth continuous complementarity problems. In addition, the global convergence of the derivative free descent algorithm is also proved.

High Thermoelectric Figure of Merit of Ag8SnS6 Component Prepared by Electrodeposition Technique

A new thermoelectric material Ag8SnS6, with ultra-low thermal conductivity in thin film shape, is prepared on indium tin oxide coated g/ass （ITO） substrates using a chemical process via the electrodeposition technique. The structural, thermal and electrical properties are studied and presented in detail, which demonstrate that the material is of semiconductor type, orthorhombic structure, with a band gap in the order of 1.56eV and a free carrier concentration of 1.46 × 10^17 cm-3. The thermal conductivity, thermal diffusivity, thermal conduction mode, Seebeck coefficient and electrical conductivity are determined using the photo-thermal deflection technique combined with the Boltzmann transport theory and Cahill＇s model, showing that the AgsSnS6 material has a low thermal conductivity of 3.8 Wm - 1K- 1, high electrical conductivity of 2.4 × 10^5 Sm- 1, Seebeck coefficient of -180μVK-1 and a power factor of 6.9mWK-2m-1, implying that it is more efficient than those obtained in recently experimental investigations for thermoelectric devices.

Task-based Language Teaching： Merits and Issues

With growing tendency and widespread application, TBLT has attracted considerable attention from educator teachers,theorists and researchers. The paper commences by offering some influential definitions of‘task', varying classifications of differ-ent types of task, and criteria for judging a task. Then, compared with teaching approaches before the emergence of CLT, TBLT isnew and has many distinct merits. Meanwhile, since it is a newly-established approach, some problems and difficulties in comple-menting TBLT are inevitable. A number of genuine issues raised in Asian language teaching classrooms are examined.

Why Merit Pay Fails:Comparison of Public and Private School Practices in Shenzhen,China

Purpose:Accounts for failures of merit pay in educational settings were stagnated by the“political obstruction hypothesis,”which blamed teacher unions for impeding the merit pay schemes from proper function.It required stronger evidence from both public and private schools to refute this hypothesis.Design/Approach/Methods:Accountability typology was conceptualized to uncover the power relations underpinning merit pay schemes,and teachers'motivational status was described from the perspective of Self-Determination Theory(SDT)to analyze the corresponding consequences.One public school and three private schools were purposefully sampled,and data included principal interviews,teacher interviews,school documents,and relevant policy documents.Findings:Our findings suggested an opposite conclusion to the“political obstruction hypothesis”that the more dependent on market,the more intense the conflict between external accountabilities and the nature of teaching.Thus,we supported the“nature of teaching hypothesis”that merit pay was inapplicable in educational settings due to the inherent contradictions between market accountability and professional accountability.Originality/Value:Policymakers and school administrators had been misled by the neoliberal initiative of borrowing merit pay into educational settings to promote the quality of teaching.Our findings provided strong evidence to refute this hypothesis and to restore the appreciation of professional autonomy.

Nonlinear optics on silicon-rich nitride--a high nonlinear figure of merit CMOS platform[Invited]

CMOS platforms with a high nonlinear figure of merit are highly sought after for high photonic quantum efficiencies, enabling functionalities not possible from purely linear effects and ease of integration with CMOS electronics. Silicon-based platforms have been prolific amongst the suite of advanced nonlinear optical signal processes demonstrated to date. These include crystalline silicon, amorphous silicon, Hydex glass, and stoichio- metric silicon nitride. Residing between stoichiometric silicon nitride and amorphous silicon in composition, silicon-rich nitride films of various formulations have emerged recently as promising nonlinear platforms for high nonlinear figure of merit nonlinear optics. Silicon-rich nitride films are compositionally engineered to create bandgaps that are sufficiently large to eliminate two-photon absorption at telecommunications wavelengths while enabling much larger nonlinear waveguide parameters （5x-500x） than those in stoichiometric silicon uitride. This paper reviews recent developments in the field of nonlinear optics using silicon-rich nitride platforms, as well as the outlook and future opportunities in this burgeoning field.

Ultra-low lattice thermal conductivity and promising thermoelectric figure of merit in borophene via chlorination

Monolayer boron-based materials are of current interests due to its polymorphism.Herein,motivated by the recent experimental synthesis of semiconducting hydrogenatedαʹ-borophene and the regulation of the physical properties in layered materials by surface functionalization,we study the thermal and electronic properties ofαʹ-borophene with three different types of gas functional groups(H,F,and Cl)based on first-principles and Boltzmann transport theory.It is found thatαʹ-borophene can be well stabilized by fluorination and chlorination and maintain the semiconductor nature.More interestingly,when hydrogen is replaced with fluorine or chlorine,the lattice thermal conductivity changes from 24.3 to 5.2 or 0.73 W/(m·K)along armchair direction at 300 K,exhibiting a huge reduction by two orders of magnitude.The main reason is the decrease of both phonon group velocities and acoustic phonon relaxation time resulting from the strong phonon mode softening due to the weaken B-B bond strength and heavier atomic mass of fluorine and chlorine.Consequently,the chlorinatedαʹ-borophene exhibits a high thermoelectric figure of merit~2 at 300 K along armchair direction.Our study illustrates the importance of the modulation of transport properties by gas functional groups,which may promote the thermoelectric application of boron-based materials.

Nonlinear optical switching and all-figures of merit in Bi2S3-xSex/PMMA nanocomposite films investigated by Z scan under visible CW laser

Bi2S3-xSex/poly(methyl methacrylate)(PMMA)nanocomposite films were prepared using microwave assisted synthesis with different compositions of x.Crystal structure,surface morphology,and optical properties were investigated to characterize the prepared nanocomposite films.The crystallinity and optical band gap of the prepared Bi2S3-xSex/PMMA were affected by x.The prepared samples showed a blue shift in the absorption edge.The laser power dependent nonlinear refraction and absorption of Bi2S3-xSex/PMMA nanocomposite films were investigated by using the Z-scan technique.The optical nonlinearity of the nanocomposite films exhibited switchover from negative nonlinear refraction to positive nonlinear refraction to negative nonlinear refraction effects,and from saturable absorption to reverse saturable absorption to saturable absorption with an increase and decrease in the composition.An interesting all-optical figure of merit was reported to assess the nanocomposite films for a practical device.It was calculated that the device all-figures of merit were based on the nonlinear response,which is important for the all-optical switching device.The results demonstrate that the optimized all-optical figures of merit can be achieved by adjusting the composition and input laser power,which can be used for the design of different all-photonic devices,and the results of nonlinear switching behavior can open new possibilities for using the nanocomposite films in laser Q-switching and mode-locking.

Calculation of the Figure of Merit of Linearly Chirped Fiber Gratings for Dispersion Compensation

At first, we systematically sum up and deduce the figure of merit of the compensator using linearly chirped fiber gratings. Secondly, we solve the Reccatti differential equation by the Runge Kutta method and calculate the reflectivity and dispersion of the linearly chirped fiber gratings to obtain the figure of merit numericallu.On the other hand, we also discuss the figure of merit under the circumstances of three kinds of coupling coefficients and compare them Finally, we present one kind of perfect design of the compensator using the Gauss coupling function, and simply discuss the method to realize the Gauss coupling function in the fabrication of linearly chirped fiber gratings in this paper.

Fano resonances with a high figure of merit in silver oligomer systems

A silver quadrumer consisting of four parallel aligned rectangular nanobars, with three at the bottom and one at the top, is proposed to provide two Fano resonances. These two resonances can be adjusted either simultaneously or independently simply by tuning the geometrical parameters. Due to the formation of the two resonances in a relatively short wavelength range, one of them can be spectrally squeezed to be very narrow, which induces a very high figure of merit(FoM =45). By decomposing the scattering spectrum into bright modes and dark modes, the double Fano resonances are found to be originated from grouping the unit cells into two different groups. The evolution of the scattering spectrum with the central dimer position along the polarization direction suggests that the symmetry reducing induces the second Fano resonance and improves the Fo M of the first one. By introducing one more nanobar into the quadrumer system, the Fo M can approach the material's limit, although the dip is relatively shallow. The ultrahigh Fo M of the Fano resonance in the proposed quadrumer can provide ultra-sensitive refractive index sensing.Furthermore, the method for providing multiple independently tunable Fano resonances can offer new solutions to designing plasmonic-related nanolasers, photocatalysis, and biochemical sensors, etc.

Here alsodiscussed are the values of the figure of merit of electronegative gases and their mixturesand the relationship of the limiting breakdown strength and the figure of meri?.

Healing,Entertaining,and Accumulating Merit:The Circulation of Medical Recipes from the Late Ming through the Qing

This article examines the circulation of medical recipes through vernacular literature and personal networks from the late Ming through the Qing.During this period,vernacular texts played a leading role in circulating practical instructions for everyday healing techniques,especially in the form of recipes.Recipes became a versatile textual form for recording and transmitting experience in quotidian practice.They moved among different genres of texts,providing information about healing,offering advice for entertainment,and delivering moral lessons.Literati sociability as well as philanthropic and religious comm Aments motivated people of varied social means to distribute vernacular texts bearing healing information to a broad audience.Recipes acquired legitimacy and authority by clearly marking their provenance and thus its relationship to particular social networks and,sometimes,a religious purpose as well.

Enhanced thermoelectric figure of merit at near room temperature in n-type binary silver telluride nanoparticles

In the present study,we have synthesized Ag2Te nanoparticles using the hydrothermal method and showed significant improvement in the thermoelectric properties compared to the bulk Ag2Te sample.Ag2Te nanoparticles showed the highest figure of merit(zT)of 1.37 at 373 K,which is the highest zT reported for this undoped material.This high zT in Ag2Te nanoparticles is mainly due to about~2 times higher electrical conductivity(1967 S/cm)and subsequently~2 times lower thermal conductivity(0.53 W/(m$K))as compared to the bulk Ag2Te sample.The higher electrical conductivity in Ag2Te nanoparticles can be accredited for two reasons(i)better mobility of the charge carrier and(ii)increased carrier concentration.The low thermal conductivity is associated with the enhanced scattering of phonons at the interface of the Ag2Te nanoparticles.
