Master curves for FENE-P fluids in steady shear flow by Yamani, Sami, McKinley, Gareth H.

“…The model contains three independent material parameters, which expressed in dimensionless form correspond to a Weissenberg number (Wi), i.e., the ratio of the dumbbell relaxation time scale to a characteristic flow time scale, a finite extensibility parameter (L), corresponding to the ratio of the fully extended dumbbell length to the root mean square end-to-end separation of the polymer chain under equilibrium conditions, and a solvent viscosity ratio, commonly denoted β. …”

Theoretical investigations and simulations of femtosecond stimulated Raman spectroscopy and coherent anti-stokes Raman spectroscopy by Li, Xiuting

“…Femtosecond stimulated Raman spectroscopy (FSRS) and coherent anti-Stokes Raman spectroscopy (CARS) as the novel techniques are widely employed to study the molecular structure and chemical reaction dynamics of physical and biological processes that occur on the ultrafast femtosecond time scale. Especially, FSRS possesses many advantages: simultaneous high temporal and spectral resolutions, free of fluorescence background, high signal-to-noise ratio, wide vibrational spectrum range and rapid data acquisition. …”

Input-to-state stability and sliding mode control of the nonlinear singularly perturbed systems via trajectory-based small-gain theorem by Jin, Zhenghong, Li, Jiawen, Wang, Zhanxiu

“…Firstly, a novel idea is proposed to analyze the stability of the nonlinear singularly perturbed system, which is regarded as an interconnected system by using two-time-scale decomposition. Secondly, the trajectory-based approach is applied to establish ISS and IOS small-gain theorem for singularly perturbed systems and the FTISS and FTIOS properties are proposed. …”

Single-Shot Quantitative Polarization Imaging of Complex Birefringent Structure Dynamics by Ge, Baoliang, Zhang, Qing, Zhang, Rui, Lin, Jing-Tang, Tseng, Po-Hang, Chang, Che-Wei, Dong, Chen-Yuan, Zhou, Renjie, Yaqoob, Zahid, Bischofberger, Irmgard, So, Peter T. C.

“…While a number of polarization microscopy techniques are available to access steady-state properties of birefringent samples, quantitative measurements of the molecular orientation dynamics on the millisecond time scale have remained a challenge. We propose polarized shearing interference microscopy (PSIM), a single-shot quantitative polarization imaging method, for extracting the retardance and orientation angle of the laser beam transmitting through optically anisotropic specimens with complex structures. …”
