a r t i c l e i n f o Keywords: Markov switching model Optimal number of states S&P 500 returns A stock market is traditionally considered to shift between bull and bear markets, reflecting the states of high mean and low mean in stock returns, respectively. In this paper, we attempt to detect more different states in a stock market by applying a Bayesian Markov switching model, where the optim...
Invasions of non-native brook trout (Salvelinus fontinalis) have the potential for upstream displacement or elimination of bull trout (Salvelinus confluentus) and other native species already threatened by habitat loss. We summarized the distribution and number of bull trout in samples from 12 streams with and without brook trout in central Idaho and used hierarchical regression analysis to con...
Bull fertility and semen quality are of paramount importance to the cattle industry. Fluorescent biomarkers measured by flow cytometry can aid in the detection of sub-fertile bulls as they can identify abnormal spermatozoa that may not be properly identified as inferior with standard methods of subjective semen analysis. This paper introduces the basics of flow cytometry, discusses fluorescent ...

background: control of the medium osmolarity and temperature during long or short time sperm manipulation is essential. objective: the objectives of the present study were to find the effects of different osmolarities of modified tyrode's solution and milk on the bull sperm during incubation at above zero temperatures. materials and methods: semen samples were collected twice from five najdi bu...
Very recently, Thomassé, Trotignon and Vuskovic [WG 2014] have given an FPT algorithm for Weighted Independent Set in bull-free graphs parameterized by the weight of the solution, running in time 2 ) · n. In this article we improve this running time to 2 ) ·n. As a byproduct, we also improve the previous Turing-kernel for this problem from O(k) to O(k). Furthermore, for the subclass of bull-fre...
This study recorded sexual behavior within a captive herd of 8 Asian elephants for approximately 230 hr on 50 days over a period of 10 months. The study observed a single adult and a single juvenile bull mounting cows more than 160 times. When the juvenile bull was between 4 years, 2 months and 4 years, 8 months old, he exhibited mounting behavior only on days when adult mounting occurred. Adul...
The aim of the study was to examine sperm viability of Pinzgau bull insemination doses following longor short-term storage. Insemination doses, provided by Slovak Biological Services Inc. (Lužianky, Slovak Republic), were slow-frozen and stored in containers with liquid nitrogen for 1 18 years. The sperm samples were divided, according to the length of storage, to the short-term ( ≤ 15 years) a...
The surface expression of CD9 (cluster-of-differentiation antigen-9) in sperms of certain mammalian species has been attributed to its fusion with the egg and thereby dictating the fertility of species. In the present study, we investigated the association of CD9 with crossbred bull sperm quality and quantity trait was analyzed using a total of 96 Frieswal (HF × Sahiwal) crossbred. A single nuc...
