Intraspecific cooperation and interspecific mutualism often feature a marked asymmetry in the scope for exploitation. Cooperation may nevertheless persist despite one-sided opportunities for cheating, provided that the partner vulnerable to exploitation has sufficient control over the duration of interaction. The effectiveness of the threat of terminating an encounter, however, depends upon the...

Interacting agents of exploiters and users within an information ecosystem may be regarded both as biological beings and as part of an economic system of infohabitants. A protection system can be implementing as a filter governing the access to assets. Typically we will have a chain of attacks and countermeasures concerning this access to the desired assets. We model this process as an arms rac...

This paper deals with the problem of coexistence in the same environment of agents with diierent attitudes towards each other. In previous works of the same authors, agents endowed with diierent help-seeking and help-giving attitudes have been deened and simulated in a multi-agent system, and the effect of their behavior on the global performance of the system has been measured. It has been sho...

The dynamics of resource patches and species that exploit such patches are of interest to ecologists, conservation biologists, modelers, and mathematicians. Here we consider how social interactions can create unique, evolving patterns in space and time. Whereas simple prey taxis (with consumable prey) promotes spatial uniform distributions, here we show that taxis in producer-scrounger groups c...

Interfacial charge transport and mobility have been studied in system-spanning nanodroplet clusters formed in water-in-oil microemulsions stabilized by non-ionic-ionic surfactant mixtures. An unexpectedly large reduction in the counterion mobility was derived from a two-step adsorption process which described the Langmuir-plot-like conductivity isotherm remarkably well. It also conformed very s...

The study aims to give equal time the issue provided by Civil Procedure Code - person’s access one of legal mechanism prerequisites- not review party’s claim without any complaint (appeal, cassation, private complaints). This, therefore, is linked subjects determination appeal court's decision. (Code Procedure, Article 364, 391 first part, second part 414) refers circle persons having right cou...

Abstract The COVID-19 pandemic has posed myriad brain-wracking questions to decision-makers at all levels. Viet Nam managed curb mortality and morbidity praiseworthy levels in the past waves, however, now had its back against wall amidst recent exponential infection cases draining medical resources. For swiftly flattening curve, legislature authorized Government take bolder steps where needed, ...
