CP violation in the B0s system

In this paper the most recent Tevatron results concerning CP violation in the B0s system are reviewed. These are the measurement of the direct CP asymmetry in the B0s->K-\pi+ decay performed by CDF and the measurement of \Delta\Gamma_s and \phi_s performed by D0 in the B0s->J/\psi\phi decay.Comment: 8 pages, 11 figures, Proceedings of the "Flavor Physics and CP Violation" Conference (FPCP07), May 12-17 2007, Bled, Sloveni

University Opera with University Symphony Orchestra - Gianni Schicchi and Buoso\u27s Ghost

Gianni Schicchi & Buoso\u27s Ghost Set in medieval Florence, the established Donati family are grieving around the deathbed of their patriarch, Buoso Donati. But when they find out he’s left their inheritance to the church - mourning turns to rage. They rope in a lower class fix-it guy, Gianni Schicchi, to change the will, in exchange for his daughter Lauretta marrying their young Rinuccio. Schicchi finds the perfect solution, executes the plan, and gets the Donati exactly what they deserve. In the sequel to Puccini’s masterpiece, Michael Ching’s Buoso’s Ghost, Schicchi discovers a dark Donati secret. When they come back to haunt him, Schicchi screams for mercy, until he conjures up a new plan, and summons the ghost of Buoso for a little help.https://digitalcommons.montclair.edu/cali-performances-2022-2023/1013/thumbnail.jp

Glassy Dynamics in a Frustrated Spin System: Role of Defects

In an effort to understand the glass transition, the kinetics of a spin model with frustration but no quenched randomness has been analyzed. The phenomenology of the spin model is remarkably similiar to that of structural glasses. Analysis of the model suggests that defects play a major role in dictating the dynamics as the glass transition is approached.Comment: 9 pages, 5 figures, accepted in J.

Dynamical characterization of monolithic MOPAs emitting at 1.5 μ�m

Eye-safety requirements in important applications like LIDAR or Free Space Optical Communications make specifically interesting the generation of high power, short optical pulses at 1.5 um. Moreover, high repetition rates allow reducing the error and/or the measurement time in applications involving pulsed time-of-flight measurements, as range finders, 3D scanners or traffic velocity controls. The Master Oscillator Power Amplifier (MOPA) architecture is an interesting source for these applications since large changes in output power can be obtained at GHz rates with a relatively small modulation of the current in the Master Oscillator (MO). We have recently demonstrated short optical pulses (100 ps) with high peak power (2.7 W) by gain switching the MO of a monolithically integrated 1.5 um MOPA. Although in an integrated MOPA the laser and the amplifier are ideally independent devices, compound cavity effects due to the residual reflectance at the different interfaces are often observed, leading to modal instabilities such as self-pulsations

Agricultural Rehabilitation and Food Insecurity in Post?war Rwanda:

Summaries Early comments on the impact of the conflict on Rwanda's food production capacity claimed that the loss of harvests and seeds was virtually total. Almost instantaneously, it was revealed that a solution existed: the ‘Seeds of Hope’ programme, a long?term international solution proposed by CGIAR through which crop production and biodiversity would be quickly restored. The restoration would prove far less expensive than long?term dependency on food aid. This article critiques the portrayal of Rwanda's agricultural devastation and offers an alternative reading. Based on research carried out on behalf of Save The Children, UK, it presents a more nuanced picture of the food and agricultural situation in the immediate aftermath of the 1994 war and genocide. This alternative reading highlights determinants of food availability overlooked in the popular portrayal of starvation and ecological calamity. Attention is paid to ecological variations within Rwanda, the differential impact caused by war and internal flight, farmer resourcefulness, and the ‘longevity’ of certain field crops not harvested on time. Immediately following the end of war, the international community failed to appreciate the diversity of conditions inside Rwanda's food production sector. Available seed supplies were never investigated, nor was the differential impact the war had had on and within Rwanda's prefectures understood. This lack of a proper needs assessment enabled the international aid world to ‘package’ Rwanda as a country whose devastated agriculture could not recover without the kind of technical, apolitical intervention the West (CGIAR) had in mind. With media assistance, CGIAR persisted with its narrative for several months despite the emergence of clear counter evidence

Differential Rotation and Magnetism in Simulations of Fully Convective Stars

Stars of sufficiently low mass are convective throughout their interiors, and so do not possess an internal boundary layer akin to the solar tachocline. Because that interface figures so prominently in many theories of the solar magnetic dynamo, a widespread expectation had been that fully convective stars would exhibit surface magnetic behavior very different from that realized in more massive stars. Here I describe how recent observations and theoretical models of dynamo action in low-mass stars are partly confirming, and partly confounding, this basic expectation. In particular, I present the results of 3--D MHD simulations of dynamo action by convection in rotating spherical shells that approximate the interiors of 0.3 solar-mass stars at a range of rotation rates. The simulated stars can establish latitudinal differential rotation at their surfaces which is solar-like at ``rapid'' rotation rates (defined within) and anti-solar at slower rotation rates; the differential rotation is greatly reduced by feedback from strong dynamo-generated magnetic fields in some parameter regimes. I argue that this ``flip'' in the sense of differential rotation may be observable in the near future. I also briefly describe how the strength and morphology of the magnetic fields varies with the rotation rate of the simulated star, and show that the maximum magnetic energies attained are compatible with simple scaling arguments.Comment: 9 pages, 2 color figures, to appear in Proc.
