Facilitating content generation via participant interactions

Abstract: Techniques are described that facilitate generating useful content based on user interactions, such as by providing an answer-providing service that facilitates interactions between users who supply questions and users who supply responses to the questions of other users, as well as using the generated content in various ways. In some situations, users are incentivized to participate in interactions with the answer-providing service in various ways, including by assessing and using levels of expertise of the users, such as for one or more categories and in a manner relative to other users. For example, the users with the highest levels of expertise and past participation may be incentivized to continue participating with the system in various ways, including by assigning one or more enhanced incentive levels to at least some such users, and then providing additional benefits of various types to users having such enhanced status.

Hypoxia adaptation in fish of the Amazon: a never-ending task

Abstract: In addition to seasonal long-term changes in dissolved oxygen and carbon dioxide, water bodies of the Amazon present periodic short-term episodes of hypoxia and even anoxia. To preserve gas exchange and acid base balance, fish of the Amazon have developed multiple adaptive solutions which occur at all biological levels. These solutions are thought to represent adaptive convergence rather than phylogenetic relatedness. Fish of the Amazon exposed to different experimental conditions adjust, for example, several parameters to improve oxygen transfer from the gas-exchange site to the tissues. These parameters include morphological changes such as the development of the lower lip in Colossoma, changes in ventilation rates, changes in circulatory parameters, increased circulating red blood cells, decreased levels of intraerythrocytic phosphates, and adjustments of intraerythrocytic pH (pHi). These adjustments that allow fish to survive both short- and long-term hypoxia occur in different degrees in different fi...

Service provider registration by a content broker

Abstract: A system, method, and computer readable medium for managing registration, by a content broker, of one or more resources with one or more service providers are provided. A content broker obtains registration information for registering the one or more resources with a service provider. The registration information may include a request to publish one or more resources to a service provider, an identification of the one or more resources, service provider selection criteria provided by the content provider or otherwise selected, and the like. The content broker transmits a service provider generation request corresponding to the registration information to the service provider. Then, the content broker manages and processes data pursuant to registration of the one or more resources with the service provider.
