Evidence of a massive planet candidate orbiting the young active K5V star BD+20 1790
(2010)
Context. BD+20 1790 is a young active, metal-rich, late-type K5Ve star. We have undertaken a study of stellar activity and kinematics for this star over the past few years. Previous results show a high level of stellar ...
X-ray groups and clusters of galaxies in the Subaru–XMM Deep Field
(2010)
We present the results of a search for galaxy clusters in the Subaru–XMM Deep Field (SXDF). We reach a depth for a total cluster flux in the 0.5–2 keV band of 2 × 10−15 erg cm−2 s−1 over one of the widest XMM–Newton ...
Information, possible worlds and the cooptation of scepticism
(2010)
The article investigates the sceptical challenge from an information-theoretic perspective. Its main goal is to articulate and defend the view that either informational scepticism is radical, but then it is epistemologically ...
MIMO-OFDM with pilot-aided channel estimation for WiMax systems
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
This paper describes a channel estimation scheme for Multiple Input Multiple Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM) systems based on training sequence. We first develop an approach to channel ...
Offering substance misuse services to Accession Eight migrants in London: Findings from a qualitative study
(2010)
This article reports findings from a study undertaken in two parts between November 2006 and May 2008, investigating the drug treatment needs of new migrants to the UK. The study explored the eligibility and treatment needs ...
Two Agents Acting as One
(MIT Press, 2010)
We consider two agents, each equipped with a controller. When they achieve a joint goal configuration, their coordination can be measured informationally. We show that the amount of coordination that two agents need to ...
Instruction cache tuning for embedded multitasking applications
(2010)
With the advent of mobile and handheld devices, power consumption in embedded systems has become a key design issue. Recently, it has been shown that cache requirements of the applications vary widely and a significant ...
Context integration in visual processing : a computational model of center-surround suppression in the visual system
(2010)
[Poster presentation]. A dysfunction of GABAergic neurotransmission is hypothesized to be an important factor in the pathophysiology of schizophrenia [1], depression and anxiety disorders. Findings of decreased center-surround ...
Whose street is it anyway? : Visual ethnography and self-reflection
(2010)
Purpose: The purpose of this paper is to apply a self-reflexive interpretive method of writing as a method of analysis of findings from a critical research based on videography documenting the relationship between ethnicity, ...
GAS in Protoplanetary Systems (GASPS) I. First results
(2010)
Context. Circumstellar discs are ubiquitous around young stars, but rapidly dissipate their gas and dust on timescales of a few Myr. The Herschel Space Observatory allows for the study of the warm disc atmosphere, using ...
