Intramolecular variations in chain molecular fluid structure
Fluid Phase Equilibria, 1993Abstract Molecular Dynamics simulations have been performed for 5-site chains mixed with single site spheres. Two separate simulations were performed at each set of conditions first with a repulsive Weeks-Chandler-Anderson (WGA) potential (Weeks et al. 1971) and then a full Lennard-Jones potential.

A variational inequality model for supply chain
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011Various types of supply chain model mainly concerns the profit of manufacturers, suppliers and customers. The manufacturers as well as the distributors are assumed to be multicriteria decision-makers and concerned not only with profit maximization but also with risk minimization.

Variational Policy Chaining for Lifelong Reinforcement Learning
2019 IEEE 31st International Conference on Tools with Artificial Intelligence (ICTAI), 2019With increasing applications of reinforcement learning in real life problems, it is becoming essential that agents are able to update their knowledge continually. Lifelong learning approaches aim to enable agents to retain the knowledge they learn and to selectively transfer knowledge to new tasks.

Stochastic Variational Inequality for Supply Chain Network
INTERNATIONAL JOURNAL ON Advances in Information Sciences and Service Sciences, 2012Abstract In this paper, we propose a stochastic variational inequality approach for a supply chain network, in which the cost functions (including both the production function and the transaction function) and the pricing cost function are contaminated by stochastic parameters.

Cytochrome P450 systems—biological variations of electron transport chains
Biochimica et Biophysica Acta (BBA) - General Subjects, 2007Cytochromes P450 (P450) are hemoproteins encoded by a superfamily of genes nearly ubiquitously distributed in different organisms from all biological kingdoms. The reactions carried out by P450s are extremely diverse and contribute to the biotransformation of drugs, the bioconversion of xenobiotics, the bioactivation of chemical carcinogens, the ...

Proximate structural mechanisms for variation in food-chain length
Oikos, 2007Food‐chain length is a central characteristic of ecological communities because of its strong influence on community structure and ecosystem function. While recent studies have started to better clarify the relationship between food‐chain length and environmental gradients such as resource availability and ecosystem size, much less progress has been ...

Intraspecific trait variation and its effects on food chains
Mathematical Biosciences, 2013Traits such as skill at foraging and investment in anti-predator defense may vary among individuals within a species population. This intraspecific variation has implications for community dynamics. The implications of intraspecific variation of a consumer in the intermediate level of a tritrophic food chain are explored for the case in which two ...
