The paper gives an overview of the modeling and analysis of autonomous control strategies for production logistics. A universal shop floor model, built with Vensim DSS, is introduced. AC strategies are discussed and implemented. The particularities of modeling a production logistic scenario are presented. Based on the simulation results the logistics performance as well as the influence on the ...

Global water scarcity is becoming a constraint for human development. Therefore there is a need to enhance water productivity of the irrigated and rainfed agriculture to meet the increasing food demand due to the population growth. This paper describes modeling efforts to assess present and future water needs for food, people and environment. This exercise is being carried out by the Internatio...

Abstract Bacteria persist under constant threat of predation by bacterial viruses (phages). Bacteria-phage conflicts result in evolutionary arms races often driven mobile genetic elements (MGEs). One such MGE, a phage satellite Vibrio cholerae called PLE, provides specific and robust defense against pervasive lytic phage, ICP1. The interplay between PLE ICP1 has revealed strategies for molecula...

Protein losing enteropathy (PLE) refers to excessive intestinal protein loss, resulting in hypoalbuminemia. Underlying pathologies include conditions leading to either reduced intestinal barrier or lymphatic congestion. We describe the case of a patient with long-lasting diffuse abdominal problems and PLE. Repetitive endoscopies were normal with only minimal lymphangiectasia in biopsies. Furthe...

BACKGROUND The purpose was to define the differences between centrilobular (CLE) and panlobular emphysema (PLE) phenotypes in cigarette smokers with COPD by a combined qualitative-quantitative computed tomography (CT) analysis. METHODS Chest CT scans of 116 cigarette smokers were visually scored by 22 chest radiologists and 29 pulmonologists in a single setting for the predominant emphysema p...

Personal learning environments (PLEs) comprise a new kind of learning technology which aims at putting learners into centre stage, i.e. by empowering them to design and use environments for their learning needs and purposes. While a lot of research and development is going on in realizing and providing technical PLE solutions, less effort is spent in examining the ‘fitness’ of PLEs. By fitness ...

Small cell lung cancer (SCLC) is characterized by a relatively high rate of autoimmune phenomena. Paraneoplastic limbic encephalitis (PLE) is an autoimmune syndrome in which a non-neural tumor containing an antigen normally present in the nervous system precipitates an antibody attack on neural tissues. Patients with PLE usually present with rapidly progressive short-term memory deficits, confu...

Papaver libanoticum is an endemic plant to Lebanese region (family Papaveraceae) that has not been investigated before. The present study aimed to explore the analgesic activity of dried ethanolic extract of Papaver libanoticum (PLE) using tail flick, hot plate, and acetic acid induced writhing models in mice. The involvement of opioid receptors in the analgesic mechanism was investigated using...

The enhanced incorporation of 32Pi into two minor acidic phospholipids, phosphatidate and phosphatidylinositol, is a response characteristic of a number of effectors, including neurotransmitters and hormones, with their receptors on the cell membrane. In the nervous system, this is perhaps best documented in the case of acetylcholine action on brain synaptosomes, slices or on sympathetic gangli...

In wireless channels, the path loss exponent (PLE) has a strong impact on the quality of links, and hence, it needs to be accurately estimated for the efficient design and operation of wireless networks. In this paper, we address the problem of PLE estimation in large wireless networks, which is relevant to several important issues in networked communications such as localization, energy-effici...
