Disclosed are a multicast data forwarding method and device supporting a virtual terminal. The method includes: a bridge forwarding module receiving multicast data sent by an end station and determining output ports; when a certain output port is the same with the input port of the multicast data and the input port has enabled reflective relay function, not carrying Ingress extended channel identifier (Ingress_E-CID) in the forwarded message information or the value of the Ingress_E-CID being zero. By modifying the source port filtering mechanism, the present invention enables a Port Extender (PE) supporting the virtual terminal technology to transmit and receive data normally while multicasting.

Embodiments of the invention provide a photoacoustic microscopy (PAM) system for observing an object. The PAM system includes an optical pickup head, an ultrasonic transducer, and an image generation unit. The optical pickup head emits a laser beam to the object, generates a servo signal based on a reflective light beam received from the object, and positions a focus of the laser beam onto the object based on the servo signal. The ultrasonic transducer detects laser-induced ultrasonic waves leaving the object to generate a PAM imaging signal. The image generation unit generates a PAM image of the object based on the PAM imaging signal.

A process useful for treating biologically derived oils in the production of biofuels is described. A biologically derived oil feed is deoxygenated by contacting the feed with a metal titanate catalyst comprising a metal titanate having an MTiO3 perovskite structure wherein M is a metal having a valence of 2+. The process does not require the addition of hydrogen.

The present invention presents an effective Cycle-count Accurate Transaction level (CCA-TLM) full bus modeling and simulation technique. Using the two-phase arbiter and master-slave models, an FSM-based Composite Master-Slave-pair and Arbiter Transaction (CMSAT) model is proposed for efficient and accurate dynamic simulations. This approach is particularly effective for bus architecture exploration and contention analysis of complex Multi-Processor System-on-Chip (MPSoC) designs.
