This paper presents the development of a bivalve farmer agent interacting with a realistic ecological simulation system. The purpose of the farmer agent is to determine the best combinations of bivalve seeding areas in a large region, maximizing the production without exceeding the total allowed seeding area.
A system based on simulated annealing, tabu search, genetic algorithms and reinforcement learning, was developed to minimize the number of iterations required to unravel a semi-optimum solution by using customizable tactics. The farmer agent is part of a multi-agent system where several agents, representing human interaction with the coastal ecosystems, communicate with a realistic simulator developed especially for aquatic ecological simulations. The… experiments performed revealed promising results in the field of optimization techniques and multi-agent systems applied to ecological simulations.
The results obtained open many other possible uses of the simulation architecture with applications in industrial and ecological management problems, towards sustainable development.
OBJECTIVE: To report a case of bilateral vocal cord abductor paralysis in the context of primary herpes simplex infection. CASE REPORT: A 63-year-old man was urgently admitted to hospital with laryngeal dyspnoea associated with dysphagia but without dysphonia. Physical examination demonstrated the vocal cords in a paramedian position with paralysis of abduction. The patient reported primary herpes simplex infection two weeks prior to this episode.
HSV serology indicated recent infection and lumbar puncture demonstrated the presence of herpes simplex virus type 1 in the cerebrospinal fluid. Complete resolution of respiratory symptoms was observed after 21 days of treatment with intravenous aciclovir. DISCUSSION AND CONCLUSION: Gerhardt syndrome comprises inspiratory dyspnoea without… dysphonia. It used to be mainly due to syphilis, but is now mostly observed in the setting of neurodegenerative disease.
The authors report a case of Gerhardt syndrome occurring after an episode of primary herpes simplex infection with the presence of herpes simplex virus in the CSF. Treatment by intravenous antiviral drugs allowed rapid resolution of the symptoms. The pathophysiology of Gerhardt syndrome remains unexplained, but the possible role of herpes simplex infection should be considered in cases of laryngeal palsy.
This paper introduces the notion of context-aware mobile hypermedia. Context awareness means to take the users’ context such as location, time, objective, community relations, etc., into account when browsing, searching, annotating, and linking. Attributes constituting the context of the user may be sensed automatically and/or be provided by the user directly.
When mobile, the user may obtain context-aware hypermedia support on a variety of small and medium sized computing platforms such as mobile phones, PDAs, tablet PCs, and laptops. This paper introduces the HyCon (HyperContext) framework with an architecture for context-aware hypermedia. The architecture includes interfaces for a sensor tier encapsulating relevant sensors and represents the hypermedia objects in structures based on… the XLink and RDF standards.
A prototype called the HyConExplorer created with the framework is presented, and it is illustrated how the classical hypermedia features such as browsing, searching, annotating, linking, and collaboration are supported in context-aware hypermedia. Among the features of the HyConExplorer are real-time location-based searches via Google collecting hits within a specified nimbus around the user’s GPS position. Finally, the use of scenarios for and evaluation of the use of the HyConExplorer in public school projects are discussed.
The transforming characteristics of the membrane complex in spermatogenesis of Fenneropenaeus chinensis have been studied by using transmission electron microscopy. Two types of membrane complex have been investigated based on their sources: one originating from nucleus and the other from cytoplasm.
The first one, consisted of annular structures, monolayer membrane blebs, and double or multi-lamellar membrane vesicles, emerges in the primary spermatocyte, then diffuses with the nuclear membrane and finally enters the cytoplasm. This type of membrane complex seems to play an important role in the materials transfusion from nucleus to cytoplasm, and it mainly exists inside the primary spermatocyte with some inside the secondary spermatocyte. The latter, originated from cytoplasm, is formed… during the anaphase of spermiogenesis. It also exists in mature sperm, locating at both sides of the nucleus under the acrosomal cap.
This type of membrane complex mainly comprises rings of convoluted membrane pouches, together with mitochondria, annular lamina bodies, fragments of endoplasmic reticulum, nuclear membrane and some nuclear particles. It releases vesicles and particles into the acrosomal area during the formation of the perforatorium, suggesting a combined function of the endoplasmic reticulum, mitochondria and Golgi’s mechanism.
This thesis argues that the motivations underpinning the mainstream news media have fundamentally changed in the 21st century. As such, the news is no longer best understood as a tool for propaganda or agenda setting; instead it seems that the news is only motivated by the flow of global network capitalism. The author contrasts the work of Noam Chomsky and Edward S. Herman with that of Gilles Deleuze.
Chomsky and Herman’s ‘Propaganda Model’ has been influential within the fields of media studies and popular culture. The ‘propaganda model’ states that the concentration of ownership of the media has allowed the media elite to exert a disproportionate amount of influence over the mass media. Deleuze, on the other hand, regards the mass media as being yet another cog within the… global capitalist mechanism, and is therefore separate from ideology or propaganda. The author proposes that ‘propaganda’ is no longer a sufficient word to describe the function of the news as terms like ‘propaganda’ imply some form of national sovereignty or governmental influence.
To highlight how the news has changed from an instrument of propaganda to an instrument of accumulation, the author compares and contrasts the coverage of the Abu Ghraib Prison Scandal with that of the Haditha Civilian Massacre. Although similar in nature, the author proposes that the Abu Ghraib Prison Scandal received a disproportionate amount of coverage within the mainstream press because of its exciting and sensational nature.
