Transient Low-mass X-ray Binary Populations in Elliptical Galaxies NGC 3379 and NGC 4278
(2009-09-01)
We propose a physically motivated and self-consistent prescription for the modeling of transient neutron star low-mass X-ray binary (LMXB) properties, such as duty cycle (DC), outburst duration, and recurrence time. We ...
A Fingerprint Matching Model using Unsupervised Learning Approach
(2009-09-01)
The increase in the number of interconnected information systems and networks to the Internet has led to an increase in different security threats and violations such as unauthorised remote access. The existing network ...
6Li/7Li estimates for metal-poor stars
(2009-09)
Context. The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-Galactic cosmic ray fusion and ...
HPV infection and immunochemical detection of cell-cycle markers in verrucous carcinoma of the penis
(2009-09-01)
Penile verrucous carcinoma is a rare disease and little is known of its aetiology or pathogenesis. In this study we examined cell-cycle proteins expression and correlation with human papillomavirus infection in a series ...
Bright Lyα emitters at z ~ 9 : Constraints on the LF from HizELS
(2009-09-01)
New results are presented, as part of the Hi-z Emission Line Survey (HizELS), from the largest area survey to date (1.4 deg ) for Lyα emitters (LAEs) at z ~ 9. The survey, which is primarily targeting Hα emitters at z <3, ...
Comparing GC and Field LMXBs in elliptical galaxies with Deep Chandra and Hubble Data
(2009-09-01)
We present a statistical study of the low-mass X-ray binary (LMXB) populations of three nearby, old elliptical galaxies: NGC 3379, NGC 4278, and NGC 4697. With a cumulative ~1 Ms Chandra ACIS observing time, we detect ...
Silicate evolution in brown dwarf disks
(2009-08-10)
We present a compositional analysis of the 10 mu m silicate spectra for brown dwarf disks in the Taurus and Upper Scorpius (UppSco) star-forming regions, using archival Spitzer/Infrared Spectrograph observations. A variety ...
An investigation of stability of a control surface with structural nonlinearities in supersonic flow using Zubov's method
(2009-08-07)
It is well known that the presence of nonlinearities may significantly affect the aeroelastic response of an aerospace vehicle structure. In this paper, the aeroelastic behaviour at high Mach numbers of an all-moving control ...
Signal Transduction Mechanisms for Stem Cell Differentation Into Cardiomyocytes
(2009-08-05)
Cardiovascular diseases are among the leading causes of death worldwide and
particularly in the developed World. The search for new therapeutic approaches for
improving the functions of the damaged heart is therefore a ...
TouchStory: Interactive Software Designed to Assist Children with Autism to Understand Narrative
(2009-08-05)
The work described in this thesis falls under the umbrella of the Aurora project (Aurora 2000). Aurora is a long-term research project which, through diverse studies, investigates the potential enhancement of the everyday ...
