let $s$ be an ordered semigroup. a fuzzy subset of $s$ is anarbitrary mapping   from $s$ into $[0,1]$, where $[0,1]$ is theusual interval of real numbers. in this paper,  the concept of fuzzygeneralized bi-ideals of an ordered semigroup $s$ is introduced.regular ordered semigroups are characterized by means of fuzzy leftideals, fuzzy right ideals and fuzzy (generalized) bi-ideals.finally, two m...

Chain restaurants will soon need to disclose calorie information on menus, but research on the impact of calorie labels on food choices is mixed. This study tested whether calorie information presented in different formats influenced calories ordered and perceived restaurant healthfulness. Participants in an online survey were randomly assigned to a menu with either (1) no calorie labels (No Ca...

In this short note we want to characterize the groups isomorphic to full automorphism groups of ordered abelian groups. The result will follow from classical theorems on ordered groups adding an argument from proofs used to realize rings as endomorphism rings of abelian groups, see [2]. Recall that H is a right ordered group (RO-group) if (H, ·) is a group and (H,<) is a linear order satisfying...

Archimedean classes and convex subgroups play important roles in the study of ordered groups. In this paper, we show that ACA0 is equivalent to the existence of a set of representatives for the Archimedean classes of an ordered abelian group. Hahn’s Theorem is the strongest known tool for classifying orders on abelian groups. It states that every ordered abelian group can be embedded into produ...

BACKGROUND The utilization of respiratory therapist (RT) driven protocols for single interventions, such as oxygen titration and bronchopulmonary hygiene, and protocols consisting of multiple interventions have been associated with improvements in resource utilization. Based on this, we started a quality improvement project to transition the delivery of respiratory care services from physician-...

In distributed applications, group communication among multiple objects is required. Group communication protocols provide a group of multiple objects with reliable data transmission service, i.e. messages are delivered to all the destination objects in the group in a well-de ned order. In the distributed applications, there are two kinds of messages, i.e. requests and responses. Many group com...
