The effect of static incubation on the yolk sac vasculature of the Japanese quail (Coturnix c. japonica) [PDF]

open access: yes, 2006
Static incubation affects early embryonic development with, notably, a reduction area vasculosa expansion and diminished sub-embryonic fluid (SEF) volume, effects produced during a ‘critical’ period (3-7 days in the chick) (Baggott et al., 2002).

From the Quantum Approximate Optimization Algorithm to a Quantum Alternating Operator Ansatz

open access: yesAlgorithms, 2019
The next few years will be exciting as prototype universal quantum processors emerge, enabling the implementation of a wider variety of algorithms. Of particular interest are quantum heuristics, which require experimentation on quantum hardware for their

Impact of breed, sex and age on hematological and biochemical parameters of local quail [PDF]

open access: yesIraqi Journal of Veterinary Sciences, 2021
The current work aimed to study the normal values of some hematological and biochemical criteria of local quail and the effect of the breed, sex, and age on them. Two hundred quail (100 birds belong to each of white and light brown feathers local breeds),

Photostimulation of Japanese quail

open access: yesPoultry Science, 2015
To adapt commercial poultry production to a new scenario of energy savings and to develop specific practices for quail production aimed at reducing costs while maintaining or improving productivity, four experiments were conducted. In the first experiment, birds were allocated to four treatments (photoperiod duration): T1: 14 L:10 D; T2: 15 L:9 D; T3 ...

Factors affecting trapping success of northern bobwhites in the rolling plains of Texas

open access: yesWildlife Society Bulletin, 2016
Trapping of northern bobwhites (Colinus virginianus) is commonly conducted for research purposes. We investigated the influence of weather, lunar phase, time of day, and season on bobwhite trapping success in the Rolling Plains ecoregion of Texas, USA ...

Zero-temperature quantum annealing bottlenecks in the spin-glass phase

open access: yesNature Communications, 2016
Quantum annealing can solve hard optimization problems, but it is limited by computational bottlenecks. Here, the author obtains the scaling of spin-glass bottlenecks with the problem size and explains a crossover to exponential complexity for large ...
