Purpose – The paper aims to explore the reasons underlying key assumption in closed-loop supply chain (CLSC) literature that consumers' purchase intention is lower for remanufactured products than new products. It complement predominantly operation-focused CLSC research by examining perception of and behavior relating Design/methodology/approach A theoretical model developed integrating concepts perceived benefits product knowledge with theory planned risk. Then examined through an empirical...
Rock mass may be exposed to high temperature and cooled by water in fire, geothermal resource exploitation deep underground engineering, which affects the safety of these engineering. In this study, cracked straight through Brazilian disc (CSTBD) specimen was used study fracture properties granite treated with different water-cooling time from 25 °C 800 °C. A camera record process specimen, evolution strain at surface obtained using digital image correlation technology, morphological...

Steering ultrafast electron dynamics with well-controlled laser fields is very important for generation of intense supercontinuum radiation. It can be achieved through coherent control the symmetry interaction between strong-field and a metal nanotip. We employ scheme two-color pulses combined weak static field to realize single quantum path generate high harmonic from solid-state nanoemitter. Moreover, smooth ultrabroad in extreme ultraviolet region obtained, which produce attosecond pulse....
An improved quantum trajectory Monte Carlo method including the Stark shift of initial state, Coulomb potential, and multielectron polarization-induced dipole potential is adopted to revisit origin low-energy interference structure in photoelectron momentum distribution xenon atom subjected an intense laser field, resolve different contributions these three effects. We found that plays essential role on structure, which moves ringlike constructive lower region. The formation a result...
By employing the frequency-domain theory, we investigate influence of polarization directions on angle-resolved photoelectron energy spectrum in above-threshold ionization (ATI) process atoms exposed to IR+XUV two-color laser fields, which shows multiplateau structures. When ionized electron is emitted along IR laser’s direction, width each plateau keeps a certain range, and jet structures main lobes are determined by both emission angle relative direction XUV field number photons absorbed...
Abstract Coulomb-corrected strong-field approximation (CCSFA), which integrates Coulomb potential and the interference effects, is a semiclassical method successful in study of atomic ionization. However, it difficult to numerically solve saddle-point equation describing tunnelling CCSFA, especially for complex laser fields such as elliptically or orthogonally polarized two-color fields. In this work, we propose an efficient based on genetic algorithm (CCSFA-GA) overcome difficulty. The...
Tunneling ionization is a crucial process in the interaction between strong laser fields and matter which initiates numerous nonlinear phenomena including high-order harmonic generation, photoelectron holography, etc. Both adiabatic nonadiabatic tunneling are well understood atomic systems. However, dynamics solids, especially tunneling, has not yet been fully understood. Here, we study sub-cycle resolved strong-field solids via complex saddle-point method. We compare instantaneous momentum...
In some practical projects, two neighboring tunnels are often constructed in natural rock bodies that have a significant number of fractures with unpredictable inclination angles and locations. To study dynamic fracture characteristics the surrounding mass twin containing crack different inclinations locations, an experimental model cracked tunnel was designed proposed, analyses were carried out by using traditional split Hopkinson pressure bar (SHPB) device digital image correlation (DIC)...

We study the multiple interference structures in photoelectron momentum distributions (PMDs) of xenon atoms, whose dynamics can be manipulated effectively by a fundamental and weaker third-harmonic two-color laser fields, especially for an oblique pattern. It is found that this structure only attributed to contributions from forward-scattered electrons as Coulomb effect strong-field physics. Further, gross arises electron ionized within quarter-cycle field, fine identified originate...
