Chooc Ly Tan is a multi-disciplinary artist, DJ and voyager who works across moving image, DJ sets, radio podcasts and club nights.Chooc Ly's practice sets out to create new visions of reality by subverting or repurposing systems and tools we use to understand the world around us – such as concepts and methodologies from physics, politics and music.
Talks she’s given include the Sonic Culture programme at CalArts (California Institute of the Arts), and Signals: Experiments in Sound at the Tate Modern, London. She is a Lecturer in Fine Art, currently teaching at The Royal College of Art, London and The Ruskin School of Art, Oxford, both in the UK

Shear Strength Measurements in LY-12 Aluminium Alloy During Shock Loading
No full textLateral stress of LY-12 alummium alloy under plate impact shock loading was measured. Based on the measured data, the Hugoniot relation and shear strength were obtained. The result has demonstrated that the shear strenath of the tested material increases remarkably with the increasing longitudinal stress. This means that the assumption of constant shear strength usually adopted in shock stress calculation is not suitable for the present material

No full textL(j, k)-labelling and maximum ordering-degrees for trees
No full text[[abstract]]Let G be a graph. For two vertices u and v in G, we denote d(u, v) the distance between u and v. Let j, k be positive integers with j >= k. An L(j, k)-labelling for G is a function f : V(G) -> {0, 1, 2, ...} such that for any two vertices u and v, vertical bar f(u) - f(v)vertical bar is at least j if d(u, v) = 1; and is at least k if d(u, v) = 2. The span of f is the difference between the largest and the smallest numbers in f (V). The lambda(j,k)-number for G, denoted by lambda(j,k)(G), is the minimum span over all L(j, k)-labellings of G. We introduce a new parameter for a tree T, namely, the maximum ordering-degree, denoted by M(T). Combining this new parameter and the special family of infinite trees introduced by Chang and Lu (2003) [3], we present upper and lower bounds for lambda(j,k)(T) in terms of j, k, M(T), and Delta(T) (the maximum degree of T). For a special case when j >= Delta(T)k, the upper and the lower bounds are k apart. Moreover, we completely determine lambda(j,k)(T) for trees T with j >= M(T)k. (C) 2009 Elsevier B.V.

ZEN2: a narrow J-band search for z similar to 9 Ly alpha emitting galaxies directed towards three lensing clusters
No full textWe present the results of a continuing survey to detect Ly alpha emitting galaxies at redshifts z similar to 9: the z equals nine' (ZEN) survey. We have obtained deep VLT Infrared Spectrometer and Array Camera observations in the narrow J-band filter NB119 directed towards three massive lensing clusters: Abell clusters 1689, 1835 and 114. The foreground clusters provide a magnified view of the distant Universe and permit a sensitive test for the presence of very high redshift galaxies. We search for z similar to 9 Ly alpha emitting galaxies displaying a significant narrow-band excess relative to accompanying J-band observations that remain undetected in Hubble Space Telescope (HST)/Advanced Camera for Surveys (ACS) optical images of each field. No sources consistent with this criterion are detected above the unlensed 90 per cent point-source flux limit of the narrow-band image, F-NB = 3.7 x 10(-18) erg s(-1) cm(-2). To date, the total coverage of the ZEN survey has sampled a volume at z similar to 9 of approximately 1700 comoving Mpc(3) to a Lya emission luminosity of 10(43) erg s(-1). We conclude by considering the prospects for detecting z similar to 9 Ly alpha emitting galaxies in light of both observed galaxy properties at z 7.LASTRONational Licence

Multiple glycosylphosphatidylinositol-anchored Ly-6 molecules and transmembrane Ly-6E mediate inhibition of IL-2 production
No full textCross-linking of Ly-6 molecules on T lymphocytes leads to IL-2 production, whereas costimulation of T cells via Ly-6A/E and the TCR inhibits IL-2 secretion. This study was initiated to determine whether there are unique structural requirements at the level of the Ly-6 molecule for its capacity to activate or block IL-2 production. Functional studies in which transfected EL-4J cells that expressed various Ly-6 proteins or chimeric Ly-6 molecules were used have demonstrated that direct activation of IL-2 secretion or inhibition of anti-CD3-induced IL-2 production occurred after mAb binding to Ly-6A/E, Ly-6C, and Ly-6G and was independent of whether the mAbs bound to amino- or carboxyl-terminal epitopes of Ly-6. The blockade of IL-2 production by costimulation with anti-CD3 and anti-Ly-6 was detected even when the addition of either mAb was temporally delayed for up to 17 h in a reciprocal fashion. Stimulation of mouse Ly-6 proteins expressed in Jurkat cells antagonized PMA/OKT3-induced IL-2 production, thus revealing that the Ly-6 inhibitory pathway is operative in human cells. EL-4J cells were also transfected with a chimeric construct in which the glycosylphosphatidylinositol anchor of Ly-6E was replaced by the transmembrane and a portion of the intracytoplasmic tail of H-2Db. Anti-Ly-6A/E also blocked anti-CD3-induced IL-2 production for these cells, although anti-Ly-6A/E failed to directly induce IL-2 secretion. Thus, anti-Ly-6A/E blockade of IL-2 production is independent of the glycosylphosphatidylinositol anchor of Ly-6E. This finding suggests that there may be aspects of signaling via Ly-6 that are solely dependent on the extracellular amino acid sequence of this protein
