Anti-Müllerian hormone (AMH) is secreted from the preantral and small antral follicles. It regulates follicle development and inhibits follicular atresia. This study examined how age, parity, and time after parturition affect plasma AMH concentrations in Japanese Black cows. We measured plasma AMH concentrations in primiparous, secundiparous, and multiparous (third parity or higher) cows at fou...
Incidence of bacterial infection in 9784 lactations of 7763 cows in 31 herds, SCC in 32,448 lactations of 19,764 cows from 54 herds, and incidence of first parity mastitis recorded in the first lactations of 148,143 cows in 828 herds were analyzed. Bacterial infection was analyzed dichotomously by both threshold and linear models. The effects of parity, season, stage of lactation, and parity by...
In this paper, a set-membership parity space approach for linear uncertain dynamic systems is proposed. First, a set of parity relations derived from the parity space approach is obtained by means of a transformation derived from the system characteristic polynomial. As a result of this transformation, parity relations can be expressed in regressor form. On the one hand, this facilitates the pa...
In this paper, the authors review use of parity as a detection observable in quantum metrology and introduce some original findings with regard to measurement resolution Ramsey spectroscopy nondemolition measures atomic parity. Parity was first introduced context an alternative state detection. It later adapted for optical interferometry where it has been shown be optimal saturating Cramér–Rao ...
First-parity 305-d milk yield and intervals between first and second kiddings from 1975 through 2005 were analyzed to estimate genetic and environmental parameters for United States Alpine, LaMancha, Nubian, Saanen, and Toggenburg dairy goats. The data set included 43,612 does with first-parity milk yield and 25,863 does with first kidding interval. Parameters were estimated by REML using bivar...
This work presents the first self-checking Booth-3 multiplier and a new self-checking Booth-2 multiplier using parity prediction. We propose a method which combines error-detection of Booth-3 (or Booth-2) decoder cells and parity prediction. Additionally, code disjointness is ensured by reusing logic for partial product generation. Parity prediction is applied to a carry-save-adder with the sta...
objective: to determine the status of serum zinc in pregnant women in different gestational ages and correlation with socio-demographic and anthropometric factors in iranian women referring to prenatal care public health clinics . materials and methods: we analyzed the zinc concentrations in plasma samples obtained at different gestational ages from 961 women and recorded bmi at the first trime...
Objective-To assess the effect of lameness on culling of dairy cows in Tehran province. Design- Historical cohort study. Study population and procedures- 7067 first- and second-parity Holstein dairy cows that calved from March, 21 2007 to March, 20 2008 were until next calving or culling. Logistic regression was conducted data. Results-The overall lactational culling rate for eligible cows i...
The negative-parity ground state of the Λ baryon lies surprisingly low in mass. At 1405.1MeV, it lies lower than the negative-parity ground state nucleon, even though it has a valence strange quark. Using the PACS-CS (2+ 1)-flavour full-QCD ensembles available through the ILDG, we employ a variational analysis using source and sink smearing to investigate the low-energy, odd-parity spectrum of ...
