We analyze the results of recent pump−probe experiments on the site-switching dynamics of Ar within cationic phenol-Ar2 clusters. A reaction-path model is employed for the wave packet dynamics. It is ...shown that the mechanism of energy dissipation is to be included to understand the features of the transient signals. Therefore, a simple recipe to include energy relaxation to the quantum dynamics is introduced. It is then possible to reproduce the measured pump−probe signals by adjustment of only two parameters.
Selective laser induced electronic transitions are influenced by fluctuating perturbations originating from collisions.
We investigate the laser induced population transfer between electronic states ...of

molecules which are subject to additional perturbations by an environment. In a former paper S. Gräfe, M. Erdmann, V. Engel, Phys. Rev. A 72 (2005) 013404 it was shown that within the formalism of
Local Control Theory, laser fields can be constructed which are able to selectively transfer population from the electronic ground to a target excited electronic state. Here, we address the question in how far the efficiency of the control process is influenced by additional perturbations. Therefore, we employ a stochastic Schrödinger equation including a fluctuation-term in the Hamiltonian.
A case of diffuse idiopathic skeletal hyperostosis (DISH) presenting with thoracic outlet syndrome and dysphagia is reported. Although extraspinal manifestations have been reported in these patients, ...thoracic outlet syndrome, particularly the anatomical anomaly found at operation, is previously unreported in patients with DISH. In addition to discussing DISH and thoracic outlet syndrome, we readvocate the anterior approach for 1st rib resection that was introduced in 1967 by Gol and associates. The direct visualization offered by this approach allowed us to avoid a potential injury to the brachial plexus that may have occurred had the transaxillary approach been used.

...it is not surprising to find every aspect of the rebirth process under scrutiny, including the juncture between two lifetimes.In non-Buddhist texts, it is the jva or atman that is said to ...transmigrate. Printed in the Netherlands.Rit he both attempts to prove that antar abhava exists and gives details of its features as part of a longer explanation of how sam. s ara proceeds.236 ROBERT KRITZERVasubandhus exposition is very well known and is a major source of a number of important articles on antar abhava, including Waymans The Intermediate State Dispute in Buddhism (1974) and Bareaus Chuu in Hob ogirin (1979). Since Vasubandhu does not disagree with Sarvastivada regarding the existence of antar abhava, his discussion of the subject is generally treated as a reliable summary of the Sarvastivadin position. ...we can get some idea of what Vasubandhu was arguing against in the Abhidharmakosabh as. ya.. ya, the main sources for reasoned. a, two arguments against the existence of antar abhavaare attributed to the Vibhajyavadins.2 According to the first, just as there is no gap between shadow and light, there can be no interval between maran. abhava and upapattibhava.3 Furthermore, just as a caterpillar4 moves along by placing its front foot down and then immediately moving its rear foot, so does a person give up the maran. abhava immediately upon obtaining upapattibhava. ...there is no interruption between maran. abhava and upapattibhava.5An argument similar to the first argument from the Vibh as. a may haveRUPA AND THE ANTAR Prior to the Abhidharmakosabh asarguments against antar abhava in which we can see alternative understandings of the transition between lifetimes are the Vibhas Sariputr abhidharma s astra, the Sam. mityanik aya s astra, and the Tattvasiddhi s astra.1. a,the S am. yukt abhidharmahr. daya, theIn the Vibhasbeen employed by the Sariputr abhidharma s astra, which is generallyconsidered not to accept antar abhava.6 This final consciousness (i.e.maran. abhava) having perished, the initial consciousness (i.e. upapattibhava) is produced in continuation in another destiny: right after the final consciousness perishes, the initial consciousness is produced. ...there is no use for an antar abhava in the process of rebirth.8 TheSam. yukt abhidharmahr. daya also refers to another simile, that of eyeconsciousness and body-consciousness at the sole of the foot.9 Finally,238 ROBERT KRITZERit mentions the simile of the caterpillar, which was explained in the Vibhas. a.10Along similar lines, the S am. mityanik aya s astra, which accepts anantar abhava and contains a long discussion of the subject, with arguments and rejoinders from both sides, presents a contrary argument that is particularly relevant to my discussion: the image is a copy of the object, as when a man is reflected in the surface of a well and his image appears.
The performance characteristics of n-link distributed amplifiers employing GaAs MESFET'S are studied. At first, formulas of tie symmetrical amplifier using lumped circuit elements are developed for ...the case of an idealized FET model. The theoretical analysis is then extended to distributed line elements and later to an S-parameter derived transistor model. In efforts to optimize amplifier performance, the restriction of circuit symmetry is subsequently removed and the performance characteristics of two concepts, that of equal characteristic impedances and that of equal line lengths, are proposed and compared. Based on this analysis and practical considerations, several three-link hybrid amplifiers utilizing the equal line lengths approach have been assembled and test results are reported. A gain of G = 5.5+-0.6 dB was measured over the bandwidth of 2-20 GHz. Across this frequency band a maximum VSWR of 2.2:1 for the input and 2.5:1 for the output terminaf have been reafized, while a minimum output power at the l-dB compression points of 19.3 dBm was achieved from 2-18 GHz. Agreement between measured and computed small-signal gain as well as reverse isolation is excellent.
Aims. We searched for very high energy (VHE) \gamma-ray emission from the supernova remnant Cassiopeia A Methods. The shell-type supernova remnant Cassiopeia A was observed with the 17 m MAGIC ...telescope between July 2006 and January 2007 for a total time of 47 h. Results. The source was detected above an energy of 250 GeV with a significance of 5.2\sigma and a photon flux above 1 TeV of (7.3 \pm 0.7_{\rm stat} \pm 2.2_{\rm sys}) \times 10 super(-13) cm super(-2) s super(-1). The photon spectrum is compatible with a power law d N /d E \propto E-\Gamma} with a photon index \Gamma = 2.3 \pm 0.2_{\rm stat} \pm 0.2_{\rm sys}. The source is point-like within the angular resolution of the telescope.
A STUDY DESCRIBING THE BENEFITS OF USING VIDEOTAPE IN CHANGING GROUP BEHAVIOR. IN ORDER TO ALLOW MEMBERS OF A GROUP TO SEE HOW THEY ARE COMMUNICATING IN WORDS AND ACTS, THE VIDEOTAPE WAS REPLAYED TO ...THE GROUP - AN IMMEDIATE SELF- IMAGE IS AVAILABLE. THE STUDY CONCLUDED-THE IMMEDIATE FEEDBACK OF THE VIDEOTAPE IS A POWERFUL TOOL FOR ASSISTING A PARTICIPANT TOWARDS BEHAVIORAL CHANGE THROUGH SELF-PERCEPTION. TO EFFECT CHANGE IN ANY GROUP, THE INDIVIDUALS WITHIN THE GROUP MUST IN MANY INSTANCES MODIFY THEIR BEHAVIOR. ATTITUDES MUST BE CAREFULLY CONSIDERED TO ACHIEVE CLOSURE ON ANY PROBLEM. GOALS AND OBJECTIVES MAY BE REACHED ONLY THROUGH COOPERATION. THROUGH THIS METHOD THE INDIVIDUAL IS ABLE TO SEE HIMSELF IMMEDIATELY AND EXACTLY AS OTHERS SEE HIM. THIS FEEDBACK IS A POWERFUL AID TO HELP PEOPLE HELP THEMSELVES TO COMMUNICATE WITH OTHERS. REFERENCES.
