The carbohydrate component of the enterobacterial common antigen (ECA) of Escherichia coli K-12 occurs primarily as a water-soluble cyclic polysaccharide located in the periplasm (ECA(CYC)) and as a phosphoglyceride-linked linear polysaccharide located on the cell surface (ECA(PG)). The polysaccharides of both forms are comprised of the amino sugars N-acetyl-D-glucosamine (GlcNAc), N-acetyl-D-m...

BACKGROUND Embodied conversational agents (ECAs) are computer-generated characters that simulate key properties of human face-to-face conversation, such as verbal and nonverbal behavior. In Internet-based eHealth interventions, ECAs may be used for the delivery of automated human support factors. OBJECTIVE We aim to provide an overview of the technological and clinical possibilities, as well ...

INTRODUCTION Acute toxic ingestion is a common cause of morbidity and mortality. Emergency physicians (EP) caring for overdose (OD) patients are often required to make critical decisions with incomplete information. Point of care ultrasound (POCUS) may have a role in assisting EPs manage OD patients. We evaluated the impact of different liquid adjuncts used for gastric decontamination on examin...

Event-condition-action (ECA) rules can specify decision processes and are widely used in reactive systems and active database systems. Applying formal verification techniques to guarantee properties of the designed ECA rules is essential to help the error-prone procedure of collecting and translating expert knowledge. However, while the nondeterministic and concurrent semantics of ECA rule exec...

Active database management systems(ADBMS) uses Event-Condition-Action rules (ECA rules). Each ECA rule speciies what action to be taken when an event occurs and the speciied condition is satissed. In this paper, we introduce a concurrency control scheme for handling nested cooperative transactions using detached mode ECA rules of an ADBMS. A state transition model has been proposed to specify d...

Event-condition-action (ECA) rules specify a decision making process and are widely used in reactive systems and active database systems. Applying formal verification techniques to guarantee properties of the designed ECA rules is essential to help the error-prone procedure of collecting and translating expert knowledge. The nondeterministic and concurrent semantics of ECA rule execution enhanc...

Passage through the digestive tract exposes Salmonella enterica to high concentrations of bile salts, powerful detergents that disrupt biological membranes. Mutations in the wecD or wecA gene, both of which are involved in the synthesis of enterobacterial common antigen (ECA), render S. enterica serovar Typhimurium sensitive to the bile salt deoxycholate. Competitive infectivity analysis of wec...

Event-Condition-Action (ECA) rules offer a flexible, adaptive, and modular approach to realizing business processes. This article discusses the use of ECA rules for describing business processes in an executable manner. It investigates the benefits one hopes to derive from using ECA rules and presents the challenges in realizing business processes. These constitute a list of requirements for an...

We describe how a functional database programming language can be extended with transactions and ECA-rules. Fundamental requirements of such an extension are that the declarative semantics of the language not be compromised, that the syntax of the language not be disrupted unduly, and that impedance mismatch problems be avoided. We deene what we mean by events, conditions and actions and descri...

The use of expanded clay aggregate (ECA) for developing lightweight concrete results in strength-reduction properties. However, the ECA-based strength properties can be improved by adding steel fibre (SF), glass mesh (GFM) and multi-walled nano-carbon tubes (MWCNT). combined effect MWCNT, GFM, SF its is still unexplored. It worth drawing a logical conclusion concerning impact on incorporating m...
