The 2dFGRS Percolation-Inferred Galaxy Group (2PIGG) catalogue of ∼ 29000 objects is used to study the luminous content of galaxy systems of various sizes. Mock galaxy catalogues constructed from cosmological simulations are used to gauge the accuracy with which intrinsic group properties can be recovered. It is found that a Schechter function is a reasonable fit to the galaxy luminosity functi...

We consider n independent, identically distributed one-dimensional Brownian motions, Bj(t), where Bj(0) has a rapidly decreasing, smooth density function f . The empirical quantiles, or pointwise order statistics, are denoted by Bj:n(t), and we are interested in a sequence of quantiles Qn(t) = Bj(n):n(t), where j(n)/n → α ∈ (0, 1). This sequence converges in probability in C[0,∞) to q(t), the α...

This study examined the intelligibility of native and Mandarin-accented English speech for native English and native Mandarin listeners. In the latter group, it also examined the role of the language environment and English proficiency. Three groups of listeners were tested: native English listeners (NE), Mandarin-speaking Chinese listeners in the US (M-US) and Mandarin listeners in Beijing, Ch...

INTRODUCTION Statins are considered potential candidate agents for melanoma chemoprevention. Statin-induced mevalonate pathway inhibition leads to reduction of cholesterol synthesis and also to decreased cellular levels of non-steroidal isoprenoids, geranylgeranyl pyrophosphate and farnesyl pyrophosphate. This results in the impairment of protein prenylation which affects carcinogenesis. AIM ...

Time series analysis plays a crucial role in understanding and predicting the path future prospects of industries, including popular music industry. This paper constructed an Box-Jenkins ARIMA (BJ-ARIMA) methodology to analyze time data industry, with focus on relationship between business culture. By employing approach, BJ-ARIMA forecast trends make informed predictions about development Ident...

A series of Pictet-Spengler condensation derivatives (tetrahydro-β-carbolines) was designed, synthesized and evaluated for lethality against a panel of seven cancer cell lines. Seven compounds (2a, 13, 20, 21, 27, 29 and 34) showed lethality in at least five cell lines. Among these, compound 27 showed a unique selectivity towards oncogenic-RAS expressing BJ-TERT/LT/ST/RAS(V12) tumor cells, comp...
