Bursting of coherent synchrotron radiation has been observed and in fact used to generate THz radiation in many electron storage rings. In order to understand and control the bursting, we return to the study of the microwave instability. In this paper, we will report on the theoretical understanding, including recent developments, of the microwave instability in electron storage rings. The hist...

Suicide bereavement evokes particular emotions that can hamper recovery processes, if neglected. This Interpretative Phenomenological Analysis (IPA) study explored five women’s experiences of following the death by suicide a male relative. One superordinate theme, directing from shadows, and three interrelated subordinate themes: roller coasting, speaking unspeakable, finding meaning living wit...

ABSTRACT The composition of relativistic outflows producing gamma-ray bursts is a long-standing open question. One the main arguments in favour magnetically dominated absence photospheric component their broad-band time-resolved spectra, with such notable example as GRB 080916C. Here, we perform analysis this burst and confirm previous detection an additional spectral component. We show that su...

This paper addresses the physical mechanism of intermittent swimming by considering burst-and-coast regime fish at different speeds. The consists a cycle with two successive phases: phase active undulation powered muscles followed passive gliding phase. Observations real whose gait is forced in water flume from low to high speed regimes are performed, using full description kinematics and mecha...

New exact solutions of Einstein’s gravity coupled to a self-interacting conformal scalar field are derived in this work. Our approach extends a solution-generating technique originally introduced by Bekenstein for massless conformal scalar fields. Solutions are obtained for a FriedmannRobertson-Walker geometry both for the cases of zero and non-zero curvatures, and a variety of interesting feat...

Ir. 1800, James Potts of London produced an artificial leg with an articulated knee and ankle, and the ankle even had a 'toe lift' during the swing phase. The leg acquired fame by being provided for the Marquis of Anglesea, who had an above-knee amputation at the battle of Waterloo in 1815. The limb bears a remarkable resemblance to those produced today. Verduin, in 1696 produced a below-knee l...

Sedimentation equilibrium was achieved with turnip yellow mosaic virus at low speeds (600 rpm) in a magnetic ultracentrifuge. The experiments were carried out in the newly installed constant-speed rotor, equipped with automatic control and an electromagnetic drive. A particle mass of 5.55 x 10(6) daltons was calculated for the virus at vanishing concentrations, in essential agreement with the e...
