Abstract: A document which may be a security document has a thermochromic coating which may be a thermochromic ink on the substrate of the document. The ink may include several thermochromic materials which transition from various different colors to substantially clear in appearance as the ink is warmed to various temperatures. The combination of the colors of the thermochromic materials can give the document a different color at a number of different temperatures, until the coating is warmed to the highest color change point. When at or above the highest color change temperature, the coating becomes substantially transparent and the printed area assumes the color of the underlying substrate. The coating may also include non-reactive materials of yet another color that mixes with the colors of the thermochromic materials.

Abstract: In a computer-implemented method of determining an abstraction of a plurality of differentiated goods available for exchange, data regarding each differentiated good is stored in a computer storage, wherein the data regarding each differentiated good includes an attribute value assigned to at least one attribute of the differentiated good. A processor of a computer determines a first abstraction of the plurality of differentiated goods based on the stored data. The first abstraction includes at least one abstract good. Each abstract good includes one or more differentiated goods. At least one abstract good of the first abstraction includes at least two distinct differentiated goods. The processor determines for each abstract good a specification for the abstract good based on the data regarding one or more differentiated goods forming the abstract good. The processor stores in the computer storage the specification determined for each abstract good.

Abstract: The present disclosure provides among other things immunoassays exhibiting reduced cross-reactivity with analyte metabolites. Additionally, the present disclosure provides diagnostic immunoassays to determine the concentration or level in a test sample of a hydrophobic drug that metabolizes in vivo or in vitro to form cross-reacting metabolites wherein cross-reactivity with such metabolites of the drug analyte is reduced. In particular, the disclosure provides such immunoassays where the hydrophobic drug is an immunosuppressant drug such as cyclosporine A.

Abstract: In a combinatorial exchange, rules can be input for processing bids and a desired exchange objective can be defined. A subset of the rules can be used to determine if an allocation of the bids exists that is optimal for the type of exchange being conducted. If the desired exchange objective is not satisfied, new allocations can be determined using different subsets of rules each time until the desired exchange objective is satisfied. At least one of the bids can include a reference ratio; a discount; a price associated with a quantity Q1 of a first item; a price associated with a quantity Q2 of a second item; and a rule that causes said discount to be applied to an average price of Q1 and an average price of Q2 for each instance of the allocated quantity Q1 over the allocated quantity Q2 that equals the reference ratio.

Abstract: In a combinatorial exchange, a set of rules can be input for processing of bids received in connection with the exchange. At least one bid can be received from each of a plurality of exchange participants and a desired exchange objective can be defined. A determination can be made as a function of a subset of the rules if an allocation of the bids exists that is optimal for the type of exchange being conducted. If the desired exchange objective is not satisfied, the step of determining an allocation is repeated utilizing a different subset of rules each time until the desired exchange objective is satisfied. It can be determined if the exchange is overconstrained and, if so, rules can be relaxed. Also or alternatively, the demand for a quantity of an item can be increased or decreased based on the average cost of the item.

Abstract: In a combinatorial exchange, rules can be input for processing bids and a desired exchange objective can be defined. A subset of the rules can be used to determine if an allocation of the bids exists that is optimal for the type of exchange being conducted. If the desired exchange objective is not satisfied, new allocations can be determined using different subsets of rules each time until the desired exchange objective is satisfied. Trigger bid groups and/or rules associated with trigger values can be used to determine whether to apply modification or discounts to bids. Item and bid groups can be partitioned into groups for the purpose of smoothing requirements. Trigger bid groups, rules associated with trigger values, item groups, and bid groups can be used for adjusting or constraining bids based on triggers, logical connectives, and adjustments.

Abstract: In a live, expressive combinatorial exchange, each of plural bidders can submit a bid. Based on the submitted bids, an allocation of the bids is determined that is optimal for the type of exchange being conducted. At least a portion of each bid of the allocation is displayed to each bidder of a first subset of the bidders that has at least one bid that is not included in the allocation. Each bidder of a subset of the first subset of bidders can then amend one or more of their existing bids or submit a new bid that is considered the next time the allocation is determined. The process of feeding back at least a portion of each bid of the allocation, submitting new bids or amendments to existing bids, and determining a new allocation based on all of the submitted bids continues until a predetermined condition is satisfied.
