This paper presents and characterizes the Princeton Application Repository for SharedMemory Computers (PARSEC), a benchmark suite for studies of ChipMultiprocessors (CMPs). Previous available benchmarks for multiprocessors have focused on highperformance computing applications and used a limited number of synchronization methods. PARSEC includes emerging applications in recognition, mining and synthesis (RMS) as well as systems applications which mimic largescale multithreaded commercial programs. Our characterization shows that the benchmark suite covers a wide spectrum of working sets, locality, data sharing, synchronization and offchip traffic. The benchmark suite has been made available to the public.

In this paper, we propose an interactive method based on Smoothed Particle Hydrodynamics (SPH) to simulate blood as a fluid with free surfaces. While SPH was originally designed to simulate astronomical objects, we gear the method towards fluid simulation by deriving the force density fields directly from the NavierStokes equation and by adding a term to model surface tension effects. In contrast to Eulerian gridbased approaches, the particlebased approach makes mass conservation equations and convection terms dispensable which reduces the complexity of the simulation.

Simulating natural phenomena like smoke, sand or fluid by physicsbased algorithms is a very complex and important task in the visual effects industry. Animating fluids is timeconsuming and the result is hard to control. There are only a few commercial fluid simulators on the market, which fit the high expectations of the effect artists. Our goal is to develop a physically correct fluid simulation system using a particlebased approach which is very scalable and flexible for special purposes.

We present a full introduction to the recent devised perturbation theory for strong coupling in quantum mechanics. In order to put the theory in a proper historical perspective, the approach devised in quantum field theory is rapidly presented, showing how it implies a kind of duality in perturbation theory, from the start. The approach of renormalization group in perturbation theory is then presented. This method permits to resum secularities in perturbation theory and makes fully algorithmical the resummation, transforming the perturbation calculations in a step by step computational procedure. The general theorem on which is founded a proper application of the strong coupling expansion, based on a result in the quantum adiabatic theory, is then exposed. This theorem gives the leading order of a strong coupling expansion. Then, after the introduction of the principle of duality in perturbation theory that puts in a proper context the quantum field theory method, the resulting theory of the strong coupling expansion and the free picture are presented. An algorithm for the computation of the perturbation series is finally given. This approach has a lot of applications in fields as quantum optics, condensed matter and so on, extending the original expectations of the quantum field theory method. So, we give some examples of application for a class of twolevel systems that, in recent years, proved to be extremely important. One of the most interesting concepts that can be obtained in 1 this way is that of a Quantum Amplifier (QAMP) that permits to obtain an amplification to the classical level of the quantum fluctuations of the ground state of a single radiation mode. 2 1

Abstract—Research and clinical applications, such as microinjection and polarbody biopsy involve 3D rotation of mammalian oocytes/embryos. In these cell manipulation tasks, the polar body of an embryo/oocyte must be made visible and properly oriented under optical microscopy. Cell rotation in conventional manual operation by skilled professionals is based on trial and error, such as through repeated vacuum aspiration and release. The randomness of this manual procedure, its poor reproducibility, and inconsistency across operators entail a systematic technique for automated, noninvasive, 3D rotational control of single cells. This paper reports a system that tracks the polar body of mouse embryos in real time and controls multiple motion control devices to conduct automated 3D rotational control of mouse embryos. Experimental results demonstrated the system’s capability for polarbody orientation with a high success rate of 90%, an accuracy of 1.9◦, and an average speed of 22.8 s/cell (versus averagely 40 s/cell in manual operation). Index Terms—Automation, cell manipulation, cell orientation, cell recognition, cell rotation, cell tracking, embryos, oocytes, polar body, 3D, visual servo. I.

Realistically animated uids can add substantial realism to interactive applications such as virtual surgery simulators or computer games. In this paper we propose an interactive method based on Smoothed Particle Hydrodynamics (SPH) to simulate uids with free surfaces. The method is an extension of the SPHbased technique by Desbrun to animate highly deformable bodies. We gear the method towards uid simulation by deriving the force density elds directly from the NavierStokes equation and by adding a term to model surface tension effects. In contrast to Eulerian gridbased approaches, the particlebased approach makes mass conservation equations and convection terms dispensable which reduces the complexity of the simulation. In addition, the particles can directly be used to render the surface of the uid. We propose methods to track and visualize the free surface using point splatting and marching cubesbased surface reconstruction. Our animation method is fast enough to be used in interactive systems and to allow for user interaction with models consisting of up to 5000 particles.

Strong coupling expansion is computed for the Einstein equations in vacuum in the ArnowittDeserMisner (ADM) formalism. The series is given by the duality principle in perturbation theory as presented in [M.Frasca, Phys. Rev. A 58, 3439 (1998)]. An example of application is also given for a twodimensional model of gravity expressed through the Liouville equation showing that the expansion is not trivial and consistent with the exact solution, in agreement with the general analysis. Application to the Einstein equations in vacuum in the ADM formalism shows that the spacetime near singularities is driven by space homogeneous equations. Keywords: Strong Coupling Expansion; ADM formalism; Homogeneous Solutions. 1.
