Abstract In this paper, the concept of generalized saddle point(GSP) is employed to discuss the optimization problems of a set of convex functions on a normed linear space X , which presents an equivalence under a special condition between GSP and its optimum solution. A study on integrated convex optimization problem by using Gâteaux and Fréchet differentiability respectivly, and the equivalen...

Geographical Social Production (GSP) is a recent phenomenon created by the confluence of geographical and the open content philosophies. In this position paper, we report a few lessons we learned through our experience and research with one such GSP system, Cyclopath, a route-finding geowiki for bicyclists. We believe these lessons would help drive critical thinking about how to make GSP system...

Recently, we have proposed an energy saving Gossip-based Sleep Protocol (GSP) [1] for energy conservation in mobile ad hoc networks. A gossiping node employs a random variable (p) to decide whether or not to enter a sleep mode. Our observation is that in a well connected ad hoc network there are usually many paths existing between a source and a destination, so a percentage (p) of the nodes may...

We introduce a bidding language for expressing negative value externalities in position auctions for online advertising. The unit-bidder constraints (UBC) language allows a bidder to condition a bid on its allocated slot and on the slots allocated to other bidders. We introduce a natural extension of the Generalized Second Price (GSP) auction, the expressive GSP (eGSP) auction, that induces tru...

Prostate cancer (PCA) is the second most frequently diagnosed and leading cause of cancer-related deaths in men in the USA. The recognition that matrix metalloproteinases (MMPs) facilitate tumor cell invasion and metastasis of PCA has led to the development of MMP inhibitors as cancer therapeutic agents. As part of our efforts to develop newer and effective chemopreventive agents for PCA, we ev...

We propose a hybrid auction mechanism for sponsored search, where bidders can be truthful or not, and are accordingly treated differently. Our class of hybrid mechanisms give incentives for non-truthful bidders to bid truthfully, while behaving as a non-truthful auction if no bidders are truthful. Our motivation is that the Generalized Second Price (GSP) auction (the current mechanism of choice...

A family of proteins designated BSP-A1, BSP-A2, BSP-A3 and BSP-30 kDa (collectively called BSP proteins for Bovine Seminal Plasma proteins) constitute the major protein fraction in the bull seminal plasma. These proteins interact with choline phospholipids on the sperm surface and play a role in the membrane stabilization (decapacitation) and destabilization (capacitation) process. Homologous p...

This paper investigates whether the 2011 expiration of the most comprehensive trade preference program (Generalized System of Preferences or GSP) offered by the US had a detrimental impact on the exports from developing countries. The impact of GSP expiration is examined with a triple difference-in-differences estimation that controls for both countryand product-level export changes. Even thoug...

School Neighbourhood Nutrition Environments (SNNEs) can facilitate or impede healthy eating. This study describes the SNNEs surrounding 6 Good Start Program (GSP) schools in 5 suburbs in Logan, Queensland. Relative density of healthy and unhealthy food outlets was calculated for SNNEs surrounding GSP (6) and non-GSP (10) schools within the 5 suburbs. Relative accessibility of minimally processe...

We introduce a measure for the level of stability against coalitional deviations, called stability scores, which generalizes widely used notions of stability in non-cooperative games. We use the proposed measure to compare various Nash equilibria in congestion games, and to quantify the effect of game parameters on coalitional stability. For our main results, we apply stability scores to analyz...
