1. The positive abundance-occupancy and abundance-variance relationships are two of the most widely documented patterns in population and community ecology. 2. Recently, a general model has been proposed linking the mean abundance, the spatial variance in abundance, and the occupancy of species. A striking feature of this model is that it consists explicitly of the three variables abundance, va...

Positron emission tomography and selective radioligands were used to determine D1 and D2 dopamine receptor occupancy induced by neuroleptics in the basal ganglia of drug-treated schizophrenic patients. In 22 patients treated with conventional dosages of classical neuroleptics, the D2 occupancy was 70% to 89%. Patients with acute extrapyramidal syndromes had a higher D2 occupancy than those with...

This paper aims to increase the memory system utilization of embedded applications. An approach is presented that inserts compression and decompression calls in the application code to reduce maximum and average memory space consumption. Memory space occupancy indicates the memory space occupied by application data at each point during the course of execution. There are two metrics associated w...

INTRODUCTION In intensive care, occupancy is a commonly used measure. There is inconsistency however in its measurement and optimal occupancy targets need to be defined. The objectives of this literature review were to explore how occupancy is measured, reported, and interpreted and investigate optimal occupancy levels for ICUs. METHOD A literature search was performed using the Medline, Emba...

Risperidone was compared with antipsychotics hitherto used for in vitro receptor binding using animal brain or cloned (human) receptors and in vivo receptor occupancy in rat and guinea pig brain following acute treatment. Both in vitro and in vivo, risperidone, 9-OH-risperidone, SM-9018, clozapine and clocapramine showed higher affinity for 5-HT2A- than for D2-receptors, whereas mosapramine, ha...

BACKGROUND A possible downstream effect of high in-hospital bed occupancy is that patients in the emergency department (ED) who would benefit from in-hospital care are denied admission. The present study aimed at evaluating this hypothesis through investigating associations between in-hospital bed occupancy at the time of presentation in the ED and the probability for unplanned 72-hour (72-h) r...

One of the more valuable and flexible forms of knowledge acquisition is based upon the use of repertory grids. A useful extension of repertory grids can be created by providing a method of semantically linking associated constructs and repertory grids. This network of grids is a semantic network with nodes consisting of individual repertory grids and links acting as ‘tracks.’ A track is a gener...

We study how the underlying graph of dependencies of one dimensional cellular automaton may be used in order to move and compose areas of computations. This allows us to deene complex cellular automata, relaxing in some way the inherent synchronism of such networks. and asynchronous computations. R esum e Nous etudions comment le graphe sous-jacent de d ependances d'un automate cellulaire de di...

Computer vision provides local environmental information for robotic navigation in crop fields. It is particularly useful robots operating under canopies of tall plants such as corns (Zea Mays) and sorghums (Sorghum bicolor), where GPS signal not always receivable. However, the development under-canopy systems still an open research area. The key contribution our work a vision-based system usin...
