Many protocols have been proposed to improve persistency and data availability in Collaborative Virtual Environments (CVEs). Two approaches have been proposed in the literature. Structured peer-to-peer network such as a distributed hash table (DHT) while the other approach uses an unstructured peer-to-peer network. With the rapidly increasing use of personal mobile devices, we are facing new op...

This paper proposes an information management system providing distribution and persistency. By separating context from virtual address space, our system has a uni ed approach for both distribution and persistency. The former is achieved by moving contexts between sites and the latter by moving contexts between virtual address space and persistent storage. Contexts include any information inclu...

The changes in egg production, in broodiness index and in plasma concentrations of LH, prolactin, oestradiol and progesterone were monitored throughout the first period of laying in turkey hens. The hens were subsequently classified according to their ability to express broodiness (33%) and their laying persistency; 25% were out-of-lay by the end of the experiment. A high percentage (67%) of th...

Given a discrete optimization problem Z(c̃) = max{c̃′x : x ∈ X}, with objective coefficients c̃ chosen randomly from a distribution θ, we would like to evaluate the expected value Eθ(Z(c̃)) and the probability Pθ(xi (c̃) = k) where x ∗(c̃) is an optimal solution to Z(c̃). We call this the persistency problem for a discrete optimization problem under uncertain objective, and Pθ(xi (c̃) = k), the persist...

We first sought to clarify the effects of discounted rate, survival rate, and lactation persistency as a component trait of the selection index on net merit, defined as the first five lactation milks and herd life (HL) weighted by 1 and 0.389 (currently used in Japan), respectively, in units of genetic standard deviation. Survival rate increased the relative economic importance of later lactati...

We use a superb five-hour sequence of 900 solar images taken at La Palma to study long-duration persistence in the solar granulation, in the context of the long-lived “intergranular holes” discovered by Roudier et al. (1997) and the contention that these mark sites of convective downflow plumes. We develop a procedure to locate “persistency regions” that contain granular brightness maxima or mi...

Objective: Persistent infection with carcinogenic human papillomavirus (HPV) causes cervical intraepithelial neoplasia (CIN) which, is commonly treated using the loop electrical excision procedure (LEEP). We investigated the factors that associate with the persistency of HPV after LEEP in patients with CIN. Methods: We retrospectively analyzed 860 CIN patients who underwent LEEP. All patients h...

The development of data centric applications should be performed in a high-level and transparent way. In particular, aspects concerning the persistency and distribution of business objects should not influence or restrict the application design. Furthermore applications should be platform independent and should be able to exchange data independently of their programming language origin. There a...

The paper presents the generalized persistency of excitation conditions. They are not only valid for much broader range of applications than their classical counterparts but also elegantly prove the validity of the latter. The novelty and the significance of the approach presented in this publication is due to employing the time averaging technique.

The C1 interior of the set of all diffeomorphisms satisfying Lewowicz’s persistency is characterized as the set of all diffeomorphisms satisfying Axiom A and the strong transversality condition. In [5], Lewowicz introduced a notion of persistency for a homeomorphism of a compact metric space X , and it is remarked that persistence is a weaker property than topological stability when X is a mani...
