In this paper, we combine the direct-forcing fictitious domain （DF/FD） method and the sharp interface method to resolve the problem of particle dielectrophoresis in two dimensions. The flow field and the motion of particles are solved with the DF/FD method, the electric field is solved with the sharp inter- face method, and the electrostatic force on the particles is computed using the Maxwell stress tensor method. The proposed method is validated via three problems： effective conductivity of particle compos- ite between two planar plates, cell trapping in a channel, and motion of particles due to both conventional and traveling wave dielectrophoretic forces.

The elasto-plastic postbuckling of fiber metal laminated beams with delamination and the energy release rate along the delamination front are discussed in this paper. Considering geometrical nonlinearity, thermal environment and geometrical initial imperfection, the incremental nonlinear equilibrium equations of delaminated fiber metal laminated beams are established, which are solved using the differential quadrature method and iterative method. Based on these, according to the J-integral theory, the elasto-plastic energy release rate is studied. The effects of some important parameters on the elasto-plastic postbuckling behavior and energy release rate of the aramid reinforced aluminum laminated beams are discussed in details.

Let G be the complexification of the real Lie algebra so（3） and A = C[t1^±1, t2^±1] be the Lau-ent polynomial algebra with commuting variables. Let L：（t1, t2, 1） = G c .A be the twisted multi-loop Lie algebra. Recently we have studied the universal central extension, derivations and its vertex operator representations. In the present paper we study the automorphism group and bosonic representations ofL（t1, t2, 1）.

We propose a new mechanism, parallel quantum Zeno dynamics, to dissipatively prepare all Bell entangled states of the twoqubit system in the context of cavity quantum electrodynamics. This mechanism can provide two transition channels between ground states and two different dark states simultaneously, which efficiently speeds up the stabilization of the entanglement and suppresses the adverse influence of surrounding environments. In addition, there is no need for the initialization of quantum states and the Clauser-Horne-Shimony-Holt inequality can be violated in a finite temperature bath. The experimental feasibility is also studied by the state-of-the-art technique and a high fidelity about 99% can be achieved.

Cognitive radio is considered as an efficient way to improve the spectrum efficiency. As one of its key technologies,spectrum handoff can guarantee the transmission continuity of secondary users(SUs). In this paper,we address a new and more generalized spectrum handoff problem in cognitive radio networks(CRNs),by considering simultaneously energy efficiency,multiple spectrum handoffs and multiple channels. Furthermore,effects of the primary users'(PUs')arrival and service rate on the target channel sequence selection are also considered. In order to obtain the energy-efficient target channel sequence,we firstly analyze the energy consumption and the number of delivered bits per hertz in the spectrum handoff process,and formulate a ratio-type energy efficiency optimization problem,which can be transformed into a parametric problem by utilizing fractional programming. Then,we propose an algorithm combining dynamic programming with bisection(DPB)algorithm to solve the energy efficiency optimization problem. Our simulation results verify that the designed target channel sequence has better performance than the existing algorithms in terms of energy efficiency.

Flexible and stretchable biosensors that can monitor and quantify the electrical or chemical signals generated by specific microenvironments have attracted a great deal of attention. Wearable biosensors that can be intimately attached to skin or tissue provide a new opportunity for medical diagnostics and therapy. In recent years, there has been enormous progress in device integration and the design of materials and manufacturing processes for flexible and stretchable systems. Here, we describe the most recent developments in nanomaterials employed in flexible and stretchable biosensors. We review successful examples of such biosensors used for the detection of vital physiological and biological markers such as gas released from organisms. Furthermore, we provide a detailed overview of recent achievements regarding integrated platforms that include multifunctional nanomaterials. The issues and challenges related to the effective integration of multifunctional nanomaterials in bio-electronics are also discussed.
