Abstract: Technologies described in this document can be embodied in a computer-implemented method that includes receiving, via an interface displayed on a computing device, an identifier associated with a publication, and retrieving, by one or more processing devices based on the identifier, a set of attributes associated with the publication. The method also includes receiving, via the interface, one or more rule parameters representing a rule based on the publication, and receiving a set of health-related parameters representing a physical condition. The method further includes determining, based on at least a portion of the health-related parameters and the one or more rule parameters, whether the rule is applicable to the physical condition, and presenting a representation of the rule on an output device as a part of a list of rules in response to determining that the rule applies to the physical condition.

Abstract: Described are methods, systems and apparatus for hypothesizing a biological relationship in a biological system. A database of biological assertions is provided consisting of biological elements, relationships among the biological elements, and relationship descriptors characterizing the properties of the elements and relationships. A biological element may be selected from the database and a logical simulation may be performed within the biological database, from the selected biological element, through relationship descriptors, along a path defined by potentially causative biological elements to discern a biological element hypothetically responsible for the change in the selected biological element.

Abstract: Disclosed are methods, systems and apparatus for constructing assemblies of biological knowledge constituting a biological knowledge base, and for subsetting and transforming life sciences-related data and information into biological models to facilitate computation and electronic reasoning on biological information. A subset of data is extracted from a global knowledge base or repository to reconstruct a more specialized sub-knowledge base or assembly designed specifically for the purpose at hand. Assemblies generated by the invention permit selection and rational organization of seemingly diverse data into a model of any selected biological system, as defined by any desired biological criteria. These assemblies can be mined easily and can be logically reasoned with great productivity and efficiency.

Abstract: Method and system for managing and evaluating life science data. Life Science data is placed in a knowledge base, that may be used for a variety of analysis tasks. Creating a knowledge base from the life science data involves generating two or more nodes indicative of life science data, assigning to one or more pairs of nodes a representation descriptor that corresponds to a relationship between the nodes, and assembling the nodes and the relationship descriptor into a database, such that at least one of the nodes is joined to another node by a representation descriptor. In some embodiments, the representation descriptor includes a case frame that describes the relationships between elements of life science data.

Abstract: A boarding stairway moves relative to fixed structure in front of it between a raised retracted position and a lowered operative position. Rollers at the top of the stairway are guided in a fixed track that is straight and vertical along most of its length from its top but curves into a short downwardly-rearwardly inclined bottom section. The stringers of the stairway rest against a roller rotatable on a fixed horizontal axis that is below and to the rear of the track; hence the bottom of the stairway swings rearward as it moves down. A counterweight that moves vertically is connected with the stairway by a cable that has a vertical front stretch extending up from the counterweight to a cable guide above the stairway and a rear oblique stretch extending down from the guide to a connection on the stairway that is spaced below its top.
