Recent work has shown that a young, rapidly rotating neutron star loses angular momentum to gravitational waves generated by unstable r-mode oscillations. We study the spin evolution of a young, magnetic neutron star including both the effects of gravitational radiation and magnetic braking (modeled as magnetic dipole radiation). Our phenomenological description of nonlinear r-modes is similar ...

We studied the evolution of isolated strange stars (SSs) synthetically, considering the influence of r-mode instability. Our results show that the cooling of SSs with nonultrastrong magnetic fields is delayed by heating due to r-mode damping for millions of years, while the spin-down of the stars is dominated by gravitational radiation (GR). Especially for the SSs in a possible existing colour-...

BACKGROUND AND STUDY AIMS Recently, tissue harmonic echo (THE) imaging has advanced with the development of a new endoscopic ultrasound (EUS) monitor/processing unit. With this new technology, penetration (THE-P) and resolution (THE-R) images can be obtained. The aim of this study was to investigate the performance of this novel THE imaging using a new processing unit for pancreatic diseases. ...

In this paper, we report observations of reduced low-k core electron temperature and intermediate-k density fluctuations in H-mode and quiescent (QH)-mode. L-mode electron temperature fluctuation levels (0.5% ̃ T e /Te 2% for k s 0.5 as measured by correlation ECE (CECE) radiometry) are observed to decrease by at least a factor of four in H and QH-mode regimes in the DIII-D tokamak (r/a = 0.7)....

This position paper explores the role of whole-brain thinking in the context of systems architecting. Brain research indicates that the brain is dual and that each of its hemispheres interprets the world differently; the concept is commonly referred to as right-brain and left-brain thinking, or sometimes R-mode and L-mode for short. L-mode denotes step-by-step linear thinking. R-mode is integra...

We develop a quantitative theory of the ratio R of radiative to non-radiative de-excitation based on the Dexter-Klick-Russell criterion for the occurrence of luminescence. The model invokes three essential elements: a promoting mode, an accepting mode, and a set of lattice modes which ultimately absorb the vibrational energy. The ratio R is determined by the relative population of the relaxed e...

We establish that in Quantum Chromodynamics (QCD) at zero temperature, SUL+R(NF ) exhibits the vector mode conjectured by Georgi and SUL−R(NF ) is realized in either the Nambu-Goldstone mode or else Q5 is also screened from view at infinity. The Wigner-Weyl mode is ruled out unless the beta function in QCD develops an infrared stable zero. PACS numbers: 11.3 Qc., 11.30.Rd., 12.38.Aw Typeset usi...

In a coalescing neutron star-neutron star or neutron star-black hole binary, oscillation modes of the neutron star can be resonantly excited by the companion during the final minutes of the binary inspiral, when the orbital frequency sweeps up from a few Hertz to a few thousand Hertz. The resulting resonant energy transfer between the orbit and the neutron star speeds up or slows down the inspi...
