Global Exponential Stability of Impulsive Functional Differential Equations via Razumikhin Technique
Shiguo Peng,Liping Yang
Abstract and Applied Analysis , 2010, DOI: 10.1155/2010/987372
Abstract: This paper develops some new Razumikhin-type theorems on global exponentialstability of impulsive functional differential equations. Some applicationsare given to impulsive delay differential equations. Compared withsome existing works, a distinctive feature of this paper is to address exponentialstability problems for any finite delay. It is shown that the functionaldifferential equations can be globally exponentially stabilized by impulseseven if it may be unstable itself. Two examples verify the effectiveness ofthe proposed results.
Strong Convergence Theorems for Countable Lipschitzian Mappings and Its Applications in Equilibrium and Optimization Problems
Yang Liping,Su Yongfu
Fixed Point Theory and Applications , 2009,
Abstract: The purpose of this paper is to propose a modified hybrid method in mathematical programming and to obtain some strong convergence theorems for common fixed points of a countable family of Lipschitzian mappings. Further, we apply our results to solve the equilibrium and optimization problems. The results of this paper improved and extended the results of W. Nilsrakoo and S. Saejung (2008) and some others in some respects.

Electrically-gated near-field radiative thermal transistor
Yue Yang,Liping Wang
Physics , 2015,
Abstract: In this work, we propose a near-field radiative thermal transistor made of two graphene-covered silicon carbide (SiC) plates separated by a nanometer vacuum gap. Thick SiC plates serve as the thermal "source" and "drain", while graphene sheets function as the "gate" to modulate the near-field photon tunneling by tuning chemical potential with applied voltage biases symmetrically or asymmetrically. The radiative heat flux calculated from fluctuational electrodynamics significantly varies with graphene chemical potentials, which can tune the coupling between graphene plasmon across the vacuum gap. Thermal modulation, switching, and amplification, which are the key features required for a thermal transistor, are theoretically realized and analyzed. This work will pave the way to active thermal management, thermal circuits, and thermal computing.
Spectrally enhancing near-field radiative heat transfer by exciting magnetic polariton in SiC gratings
Yue Yang,Liping Wang
Physics , 2015,
Abstract: In the present work, we theoretically demonstrate, for the first time, that near field radiative transport between 1D periodic grating microstructures separated by subwavelength vacuum gaps can be significantly enhanced by exciting magnetic resonance or polariton. Fluctuational electrodynamics that incorporates scattering matrix theory with rigorous coupled wave analysis is employed to exactly calculate the near field radiative heat flux between two SiC gratings. Besides the well known coupled surface phonon polaritons (SPhP), an additional spectral radiative heat flux peak, which is due to magnetic polariton, is found within the phonon absorption band of SiC. The mechanisms, behaviors and interplays between magnetic polariton, coupled SPhP, single interface SPhP, and Wood's anomaly in the near field radiative transport are elucidated in detail. The findings will open up a new way to control near field radiative heat transfer by magnetic resonance with micro or nanostructured metamaterials.
The scaling properties of dynamical fluctuations in temporal networks
Liping Chi,Chunbin Yang
Physics , 2015,
Abstract: The factorial moments analyses are performed to study the scaling properties of the dynamical fluctuations of contacts and nodes in temporal networks based on empirical data sets. The intermittent behaviors are observed in the fluctuations for all orders of the moments. It indicates that the interaction has self-similarity structure in time interval and the fluctuations are not purely random but dynamical and correlated. The scaling exponents for contacts in Prostitution data and nodes in Conference data are very close to that for 2D Ising model undergoing a second-order phase transition.
Spectrally enhancing near-field radiative transfer between gold gratings by exciting magnetic polariton in nanometric vacuum gaps
Yue Yang,Liping Wang
Physics , 2015,
Abstract: In the present work, we theoretically demonstrate that near field radiative transport between one dimensional periodic grating microstructures separated by nanometer vacuum gaps can be spectrally enhanced by exciting magnetic polariton. Fluctuational electrodynamics that incorporates scattering matrix theory with rigorous coupled wave analysis is employed to exactly calculate the near field radiative flux between two gold gratings. Besides the well known coupled surface plasmon polaritons, the radiative flux can be also spectrally enhanced due to magnetic polariton, which is excited in the gap between gold ridges. The mechanisms of magnetic polariton in the near field radiative transport are elucidated in detail, while the unusual enhancement cannot be predicted by either the Derjaguin or effective medium approximations. The effects of vacuum gap distance and grating geometry parameters between the two gratings are investigated. The findings will open up a new way to control near field radiative transfer by magnetic polariton with micro or nanostructured metamaterials.
Effects of ytterbium on outward K+ currents in NIH3T3 cell
LiPing Zhang,Ming Chen,Pin Yang
Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-009-0690-5
Abstract: Using the whole cell patch-clamp technique, we observed the outward K+ currents and studied for the first time the effects of Yb3+ on the currents and kinetics of activation and inactivation in non-excitable NIH3T3 cell. Our results show that the outward K+ currents were promoted with increasing concentration of Ca2+ in pipette solution and saturated at the concentration of 100 μmol/L Ca2+. Yb3+ in bath solution inhibited the currents in a concentration-dependent manner. At the concentration of 1 μmol/L, Yb3+ significantly changed the V h of activation curve and shifted the activation curve to more negative potentials, but with no effect on its slope factor k. Meanwhile, it had no effect on the inactivation curve. Potassium currents inhibition can induce a series of physiological and molecular biological functions, presumably because of its ability to depolarize the plasma membrane and enhance cell excitability resulting in increasing Ca2+ influx and cytoplast Ca2+ concentration. This process may be one of the molecular mechanisms to affect cell division and proliferation of Yb3+ on NIH3T3 cells.

From Cross-cultural Psychology to Cultural Constructionist Psychology: The Evolution of the Cultural Consciousness in Psychology
从跨文化心理学到文化建构主义心理学--心理学中文化意识的衍变

Yang Liping,
杨莉萍

心理科学进展 , 2003,
Abstract: 心理学中的化意识在跨化心理学、化心理学、化建构主义心理学中经历了3次重大衍变。跨化心理学视化为心理规律的干扰因素,认为理论研究应力求“去化”;化心理学认为心理是化的“投射”,寻求理论的“化敏感”;化建构主义心理学则认为心理与化是相互灌注、相互建构的关系,因而更加关注“心理”、“意义”与“现实”的双向建构过程。本详细分析了上述几种不同的化意识形态的主要特点,并结合历史背景对其各自的意义、问题做了简要讨论。
