This study examines the potential profit of bull flag technical trading rules using a template matching technique based on pattern recognition for the Nasdaq Composite Index (NASDAQ) and Taiwan Weighted Index (TWI). To minimize measurement error due to data snooping, this study performed a series of experiments to test the effectiveness of the proposed method. The empirical results indicated th...

Bull sperm that had been extracted with 0.2% Triton X-100 could be reactivated with ATP, and their movement closely resembled the motion of intact live sperm. Their motility required the presence of ATP, magnesium, and a medium of suitable salt concentration and pH. When Triton-extracted bull sperm were digested breifly with trypsin at pH 9.0, they appeared to reatin most of their normal struct...

Semen may be collected from the vagina of the recently bred cow with the hand, by aspiration, or with a sponge. Semen from the vagina is satisfactory for determining whether the bull has ejaculated normal active spermatozoa during the mating, but it is unsatisfactory for use in physiological studies of spermatozoa because it is mixed with the secretions of the cow. Furthermore, collecting semen...

Traditional methods used to partition the market index into bull and bear regimes often sort returns ex post based on a deterministic rule. We model the entire return distribution; two states govern the bull regime and two govern the bear regime, allowing for rich and heterogeneous intra-regime dynamics. Our model can capture bear market rallies and bull market corrections. A Bayesian estimatio...

The recently announced Strong Perfect Graph Theorem states that the class of perfect graphs coincides with the class of graphs containing no induced odd cycle of length at least 5 or the complement of such a cycle. A graph in this second class is called Berge. A bull is a graph with five vertices x, a, b, c, d and five edges xa, xb, ab, ad, bc. A graph is bull-reducible if no vertex is in two b...

Background Although artificial insemination (AI) technique is an established biotechnology for bovine reproduction, the results of AI (conception rates) have a tendency to decline gradually. To our annoyance, moreover, AI-subfertile bulls have been occasionally found in the AI centers. To resolve these serious problems, it is necessary to control the sperm quality more strictly by the examinati...

Using the threshold structural VAR model, this paper examines the multiheterogeneity impacts of international oil price shocks on Chinese stock market in the background of financialization. The research finds: (1) the effects of oil price shocks on stock returns are different across sectors and the responses of stock returns are larger in bear markets. The nonlinear effects of oil supply shocks...

A between participants design was employed to test for the effects of Red Bull on cognitive abilities in a placebo controlled experiment outside of a laboratory setting. A total of 49 volunteer participants took part and were randomly allocated to either the Red Bull (250ml’s) (N=15), placebo beverage (250ml’s) (N=20) or control group (no drink) (N=14). An online computerised experiment tested ...

There are numerous factors which need to be considered when selecting a bull to mate over heifers. In many cases, the primary aim of the beef producer is to produce a live calf which is born unassisted, with other economic traits (e.g. growth) of secondary importance. Traditionally this has been done by selecting a ‘heifer bull’ to mate over the heifers; that is, a bull with a low birth weight ...

We apply a logistic smooth transition market model (LSTM) to a sample of returns on Australian industry portfolios to investigate whether bull and bear market betas differ. Unlike other studies, our LSTM model allows for smooth transition between bull and bear states and allows the data to determine the threshold value. The estimated value of the smoothness parameter was very large for all indu...
