The use of multithreading can enhance the performance of a software system. However, its excessive use can degrade the performance. For example, a thread-per-job approach might lead to a large amount of threads with increased associated overheads. In this paper we explore the use of the Parallelism Viewpoint to support one possible strategy to reduce the number of threads, namely finding candid...

We study a multilocation newsvendor network when the only information available on joint distribution of demands are values its mean vector and covariance matrix. adopt distributionally robust model to find inventory levels that minimize worst-case expected cost among distributions consistent with this information. This problem is NP-hard. closed-form tight bound there two locations. under fami...

Energy transfer (ET) from excited matrix to fluorescent traps is used to probe the mobility of excitations in the matrix-assisted laser desorption/ionization (MALDI) matrix material 2,5-dihydroxybenzoic acid. The dependence of host and guest fluorescence on excitation density (laser intensity) and trap concentration gives clear evidence for long-range energy transport in this matrix. This concl...

This paper considers the effect of bans on insurance risk classification utilitarian social welfare. We consider two regimes: full classification, where insurers charge actuarially fair premium for each risk, and pooling, is banned institutional or regulatory reasons, do not attempt to separate classes, but a common all risks. For iso-elastic demand, we derive sufficient conditions higher lower...

This paper considers a single-sourcing network design problem for a three-level supply chain. For the first time, a novel mathematical model is presented considering risk-pooling, the inventory existence at distribution centers (DCs) under demand uncertainty, the existence of several alternatives to transport the product between facilities, and routing of vehicles from distribution centers to c...

We examine equilibria in competitive insurance markets when individuals take unobservable labor supply decisions. Precautionary labor motives introduce countervailing incentives in the insurance market, and equilibria with positive profits can occur even in the standard case in which individuals exogenously differ in risk only. We then extend the model to allow for both privately known risks an...
