Balanced Vertices in Trees and a Simpler Algorithm to Compute the Genomic Distance [PDF]

open access: yes, 2010
This paper provides a short and transparent solution for the covering cost of white-grey trees which play a crucial role in the algorithm of Bergeron {\it et al.}\ to compute the rearrangement distance between two multichromosomal genomes in linear time (

Landscape for children to play and learn: A conceptual framework [PDF]

open access: yes, 2005
Play and movement are at the very center of young children’s lives. Allowing the children to experience the natural and man-made elements in their living environments would generate cognitive, physical and social skills and developments.

What asteroseismology can do for exoplanets

open access: yes, 2015
We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of stellar inclinations; and (3) the determination of orbital eccentricity from ...

Quantum computing of molecular magnet Mn$_{12}$ [PDF]

open access: yes, 2002
Quantum computation in molecular magnets is studied by solving the time-dependent Schr\"{o}dinger equation numerically. Following Leuenberger and Loss (Nature (London) 410, 789(2001)), an external oscillating magnetic field is applied to populate and ...

Experimental Study of the Radiative Decays K+ -> mu+ nu e+e- and K+ -> e+ nu e+e-

open access: yes, 2002
Experiment 865 at the Brookhaven AGS obtained 410 K+ -> e+ nu e+e- and 2679 K+ -> mu+ nu e+e- events including 10% and 19% background. The branching ratios were measured to be (2.48+-0.14(stat.)+-0.14(syst.))x10^-8 (m_ee>150 MeV) and (7.06+-0.16+-0.26 ...

Low-temperature measurement of the fundamental frequency response of a semiconductor laser by active-layer photomixing [PDF]

open access: yes, 1989
We use the active-layer photomixing technique to directly modulate the output of a GaAs semiconductor laser operating at temperatures as low as 4.2 K. The technique produces modulation with nearly perfect immunity to device parasitic effects, revealing ...

Fine structure of the 410-km discontinuity [PDF]

open access: yes, 1998
The April 14, 1995, earthquake in western Texas (M_w 5.7) produced a strong topside reflection off the 410-km discontinuity which was recorded on a multitude of seismic arrays throughout the southwestern United States. Data from 394 vertical short-period
