Abstract An R 2 O–B O 3 –SiO (R = Li, Na, K) polarizing glass containing Ag nanorods is prepared by thermal elongation–reduction technology. The transverse and longitudinal plasmon absorption peaks of the embedded are near 460 720 nm, respectively. When polarization laser parallel to long axis nanorods, nonlinear coefficient β 0.82 cm GW –1 refractive index n –1.5 × 10 –4 . light perpendicular 0.12 –7.2 –5 appropriate one‐ two‐photon figures merit (FOM), W 1.6 T 0.16, respectively, obtained,...
The innovation value chain is an effective tool for analysing activities and reflects the process of creation increase in activities. From perspective chains, we divided patent into three stages: knowledge stage, applied research stage commercialization stage. panel data from 64 universities directly managed by Ministry Education 2009 to 2017 were used several conclusions drawn: 1) In initial innovation, fundamental fund plays a crucial promoting role, achievements are mainly published...
Purpose While implementing green innovation-driven strategies when facing growing grim environmental problems and the realistic demands of achieving high-quality development is increasingly urgent, changing abruptly inevitably detrimental to smooth functioning social economic development. Restrained by resources, strategy a huge for an organization shift from traditional technological innovation innovation. Supports implementation in technology investment would necessarily crowd out other...
Sluggish status of green technology development has stimulated research into new incentives and pathways. Beyond the traditional regulatory-push demand-pull approaches, we reposition strength push. Based on innovation diffusion theory, a multidimensional path model knowledge spillover in universities is constructed, impact heterogeneous channels activities local firms discussed. We find that R&D collaboration significant effect firms' quality but not quantity innovation. Contrarily, patent...
ABSTRACTThe relationship between halo effect and cross-regional commercialisation of technology in universities is a very important issue that has not been answered theoretically. Based on signal theory information asymmetry theory, with different reputations have their scope influence competitive advantages, studying the under political border worthwhile. Given panel data directly Ministry Education, reputation non-linear, is, mechanism plays prominent role after breaking province boundary....
This paper is concerned with electric–acoustic/acoustic–electric conversions of thin-wafer piezoelectric transducers polarized in the thickness direction. By introducing two mechanical components frequency-dependent values, i.e., radiation resistance and mass, into equivalent circuit transducer, we established a dynamic mechanic-electric network four terminals for an arbitrary given frequency, enhancement from conventional networks. We derived analytic expressions its electric–acoustic...
We reported photochromism and largely enhanced visible two-photon luminescence (TPL) of Ag-TiO(2) granular composite films by using ps/fs laser at the wavelength 800 nm. Three types spectra were observed when Ag atom fraction are less than, comparable to larger than percolation threshold. The strong surface-plasmon-resonance TPL emissions near Ag(2)O transition band from photoactivated samples also observed. Furthermore, we found that intensity saturatedly increased while absorbance nm...
The complexity of metabolic profiles makes chemometric tools indispensable for extracting the most significant information. Partial least‐squares discriminant analysis (PLS‐DA) acts as one effective strategies data in metabonomics. However, its actual efficacy metabonomics is often weakened by high similarity profiles, which contain excessive variables. To rectify this situation, particle swarm optimization (PSO) was introduced to improve PLS‐DA simultaneously selecting optimal sample and...
In solving piezoelectric equations of motion, we established an electric-acoustic equivalent circuit tangentially polarized thin cylindrical transducers and derived analytical expressions the response from harmonic driving-voltage excitation. To experimentally verify findings, manufactured a parallel transmission network for excited by multifrequency driving signals. We found that achieved much higher conversion efficiency than radially transducers. The impulse consisted direct-current...
The traditional acoustic attenuation coefficient is derived from an analogy of the electromagnetic wave propagating inside a non-ideal medium, featuring only propagation. Nonetheless, particles viscous solids have mass, vibrating energy, viscosity, and inertia motion, they go through transient damping processes. Based on long-wavelength approximation, in this paper, we use energy conservation law to analyze effect viscosity medium attenuation. We derive by combinations dynamical equation...
Currently, the rapid population aging has posed a series of challenges for economic and social development in China.Facing with these problems, Chinese government planned to formulate policies progressive delay retirement age, regarded "positive response aging" as one long-term strategy.But reality, China's per capita life expectancy human capital cycle "double extended", "old before getting rich" makes re-employment elderly become very urgent.Based on current aging, this paper analyzed...
<title>Abstract</title> Particle-reinforced composites (SiCp/Al) are widely used in aerospace and military industries due to their excellent properties. Heating SiCp/Al with a pulsed laser softens the material, which reduces cutting forces, decreases tool wear improves surface quality. During heating-assisted of SiCp/Al, modeling force prediction is complicated by laser's involvement material temperature increase its property changes. Therefore, model was developed considering effect heating...
Agricultural irrigators and industrial water users are two kinds of subjects in the market rights trading.In this paper, evolutionary game method multi-agent simulation were used to analyze non-collaborating coopetitive behavior these agents.The main conclusions study increased benefits brought by collaboration reward punishment will promote development co-operation.The greater values are, more can be promoted.When one party chooses collaborate other non-collaborate, non-collaborative...
This paper takes an electronic information university with obvious industry characteristics as example, and conducts data mining research on the school's 2016-2018 graduate training data. basis of literature reading sorting, select whether to enter world's top 500 work in economically developed area employment quality evaluation indicators, use 12 indicators that may affect for cross-statistical analysis.

Abstract We report acoustic impulse-response and system function of particle vibration inside viscous, dense solids explain the physical mechanism intrinsic-noise generation. With an external disturbance a harmonic force acting on particles viscous solid media, goes through gradual transition from static state to steady vibrational state. Based damped oscillator model, frequency spectrum resembles intrinsic noise generated by vibrating in isotropic solids, which delivers crucial...
