Abstract Circular photocurrents (CPC), namely circular photogalvanic (CPGE) and photon drag effects, have recently been reported both in monolayer multilayer transition metal dichalcogenide (TMD) phototransistors. However, the underlying physics for emergence of these effects are not yet fully understood. In particular, CPGE is compatible with D 3h crystal symmetry two-dimensional TMDs, should ...

Tunnel Broker model, as defined in RFC3053, is a solution to the automation of IPv6 address assignment and IPv6 over IPv4 tunnel management. Tunnel server selection and fault tolerance are two big problems for a Tunnel Broker system. Anycast makes it possible to solve the tunnel server selection problem and improve the system’s fault tolerance. This paper proposes an architecture of the Tunnel ...

Numerical simulations of the unsteady flow over a low-aspect-ratio, low Reynolds number semi-circular planform wing are performed using Lattice Boltzmann method. The simulations exactly match the flow conditions and the detailed geometry from previous wind-tunnel experiments, including the flow actuators installed internally along the leading edge of the wing. To reproduce the pulsed-blowing ac...

The present work is devoted to develop a numerical wind tunnel to study the local turbulent flow fields over complex topography by using large eddy simulation. Firstly, the mean and turbulence flow over flat terrain and that over a steep 3-dimensional circular hill were simulated and the accuracy of these computations was assessed by comparing the results with those from the experiment. Then th...

Axial flow fan has been used for large amount of flow rate in air handling units of industrial application fields. The fan involves a shrouding duct as flow guidance for uniform flows. Pressure difference between before and ahead of rotating blades causes the flows movements. The case where the flow resistance such as a heat exchanger is located prior to the rotors is typical in-field model for...

Vortex shedding from cylinders has been extensively studied due to its occurrence in many engineering fields. Many experimental studies reported in the literature focus on the aerodynamics of the vortex shedding process but the literature about the radiated noise is more scarce. The aim of the work presented here is to extend the available noise data. Aero-acoustic wind tunnel tests were carrie...

Nano-scale patterned techniques, DCpulsed-current-driven magnetization switching and spin-dependent transport properties of magnetic tunnel junctions (MTJs) are presented in this paper. The experiments show that the spin transfer torque (STT) plays a main switching role in the magnetization current switching and the current-induced circular magnetic field plays an assisted-switching role in the...

The treatment of patients with achalasia is complex due to a considerably high recurrence rate and risk of treatment-related complications. The per-oral endoscopic myotomy (POEM) is a new endoscopic technique that combines the benefits of a minimally invasive endoscopic procedure with the efficacy of a surgical myotomy. Implementation of the POEM technique may lead to fewer complications, a low...
