The objectives of our study were to propose a new definition for persistency of egg production and to develop a mathematical model to describe the egg production curve, one that includes a new measure for persistency, based on the proposed definition, for use as a selection criterion to improve total egg production. Persistency of egg production is an important determining factor for total egg ...

Cows with high persistency tend to produce less milk than expected at the beginning of lactation and more than expected at the end. Best prediction of persistency was calculated as a function of a trait-specific standard lactation curve and a linear regression of test-day deviations on days in milk. Regression coefficients were deviations from a balance point to make yield and persistency pheno...

Contact Information: Andrew Shim, PharmD, JD, MAM; email: [email protected] Among insured patients, out-of-pocket costs for biologics may be high. Previous research suggests higher cost-sharing for biologics is associated with higher rates of abandonment (failure to pick up a filled prescription at the pharmacy). Higher out-of-pocket costs also may affect medication persistency (continuat...

BACKGROUND Availability of oral disease-modifying therapy (DMT) for relapsing-remitting multiple sclerosis (RRMS) may affect injectable DMT (iDMT) treatment patterns. OBJECTIVE The objective of this paper is to evaluate iDMT persistency, reasons for persistency lapses, and outcomes among newly diagnosed RRMS patients. METHODS Medical records of 300 RRMS patients initiated on iDMT between 20...

Flexible and performant Persistency Service is a necessary component of any HEP Software Framework. The building of a modular, non-intrusive and performant persistency component have been shown to be very difficult task. In the past, it was very often necessary to sacrifice modularity to achieve acceptable performance. This resulted in the strong dependency of the overall Frameworks on their Pe...

Persistency of lactation is the ability of a cow to continue producing milk at a high level after the peak of her lactation. Differences in persistency, if not properly accounted for, reduce accuracy of genetic evaluation when incomplete records are used. Persistency has also direct economic value. Reduction of feed, health and reproductive costs are the major factors which favour more persiste...

Cows with high lactation persistency tend to produce less milk than expected at the beginning of lactation and more than expected at the end. Best prediction of lactation persistency is calculated as a function of trait-specific standard lactation curves and linear regressions of test-day deviations on days in milk. Because regression coefficients are deviations from a tipping point selected to...

The classical notion of persistency, originated in 60s, has been extensively studied up to now. An action of a processing system is said to be persistent if, whenever it becomes enabled, it remains enabled until executed. And a system is said to be persistent if each of its actions is persistent. This notion, introduced by Karp/Miller, is one of the most frequently discussed issues in the Petri...

Persistency is one of the notions widely investigated due to its application in concurrent systems. The classical notion refers to nets with a standard sequential semantics. We will present two approaches to the issue (nonviolence and persistency). The classes of different types of nonviolence and persistency will be defined for nets with step semantics. We will prove that decision problem conc...
