Two methods for analyzing graphs such as those occurring in the stock market, geographical profiles and rough surfaces, are investigated. They are based on different scaling laws for the distributions of jumps as a function of the lag. The first is a large deviation analysis, and the second is based on the concept of a self-similar process introduced by Mandelbrot and van Ness. We show that lar...

In this study, we demonstrate how price limits can affect a return series on limit-hitting days. Our identification of two effects – a ceiling effect and a cooling or heating effect (C-H effect) is based on a resampling method suggested by Wei and Chiang (1999). We estimate the C-H effect by assuming that the return series will have a mixture normal density instead of a simple normal density. W...

Over the past two decades a number of Chinese companies have issued shares on both the Hong Kong Stock Exchange and on one of the Chinese stock exchanges. The Hong Kong-listed H-shares of Chinese dual-listed companies have traded at a persistent discount rate relative to the China-listed A-shares. As these shares represent the same ownership rights and cash flows, the shares should theoreticall...

We report an empirical study of the Ibovespa index of the São Paulo Stock Exchange in which we detect the existence of long-range correlations. To analyze our data we introduce a rescaled variant of the usual Detrended Fluctuation Analysis that allows us to obtain the Hurst exponent through a one-parameter fitting. We also compute a time-dependent Hurst exponent H(t) using three-year moving tim...

This study estimated the length-weight relationship, sex ratio and population parameters of mantis shrimp, Harpiosquilla harpax from the coastal waters of Pantai Remis, Perak, Malaysia between February 2012 and October 2012. Total length and weight of 804 specimens of H. harpax were measured and the sex ratio was 1: 0.83 (M: F). Males of H. harpax were dominant over the females throughout the s...

During the last few years, a considerable amount of work has been done on the hydrogen ion concentration of the blood in health and disease, as well as on its influence on the rate of multiplication of bacteria in artificial media. Whilst working in Dr. H. H. Dale's laboratory I noticed whilst testing the action of the cinchona alkaloids on Paramecium caudatum. that this ciliate was easily dest...

Models of stock price prediction have traditionally used technical indicators alone to generate trading signals. In this paper, we build trading strategies by applying machine-learning techniques to both technical analysis indicators and market sentiment data. The resulting prediction models can be employed as an artificial trader used to trade on any given stock exchange. The performance of th...

We report the molecular cloning of two replication-competent osteoma-inducing murine leukemia viruses from the RFB osteoma virus stock (M. P. Finkel, C. A. Reilly, Jr., B. O. Biskis, and I. L. Greco, p. 353-366, in C. H. G. Price and F. G. M. Ross, ed., Bone--Certain Aspects of Neoplasia, 1973). Like the original RFB osteoma virus stock, viruses derived from the molecular RFB clones induced mul...

It has now been 30 years since the implantable cardioverterefibrillator (ICD) was introduced to the cardiovascular ommunity for the prevention of sudden cardiac death 1). Perhaps it is no longer common knowledge that the efibrillator was conceived and initially developed 40 ears ago by Drs. Michel Mirowski and Morton Mower, ot in an eminent medical institution with the robust upport of industry...
