We introduce a new operation on skew diagrams called composition of transpositions, and use it and a Jacobi-Trudi style formula to derive equalities on skew Schur Q-functions whose indexing shifted skew diagram is an ordinary skew diagram. When this skew diagram is a ribbon, we conjecture necessary and sufficient conditions for equality of ribbon Schur Q-functions. Moreover, we determine all re...

In this paper, we develop a supply chain game theory framework consisting of retailers and consumers who engage in electronic transactions via the Internet and, hence, may be susceptible to cyberattacks. The retailers compete noncooperatively in order to maximize their expected profits by determining their optimal product transactions as well as cybersecurity investments in the presence of netw...

Market equilibrium theory assumes that agents are truthful, and are generally unaware of the total supply of goods in the market. In this paper, we study linear exchange markets with each of these assumptions dropped separately, and show a surprising connection between their solutions. We define the exchange market game as where agents strategize on their utility functions, and we derive a comp...

This paper proposes and evaluates a model of supply chains as networks of auctions. In this model, companies are represented according to the first level of the Supply Chain Council’s SCOR model and the trading strategy of the agents is adapted from a model proposed by Steiglitz and colleagues. Specifically, the highest level of SCOR treats a company as comprising three functions, namely Source...

Major functions of portal-drained viscera (PDV) and liver of cattle include absorption of digestion products and modification of the body's supply of intermediary metabolites. The disproportionately high metabolic rate of PDV and liver (7-13% of body tissues) is exemplified by their oxygen uptake (40-50% of whole body). Extensive metabolism of glucose, volatile fatty acids and amino acids by PD...

Automation and optimisation of supply-chain activities are made possible by radio frequency identification (RFID) technology. RFID supply chain performance can be enhanced by integrating RFID functions into the web service paradigm. However, the use of RFID involves growing privacy and security concerns, in part because the lack of RFID tag capacity places the whole supply-chain loop at risk of...
