Sponsored Search Auctions (SSAs) are one of the most successful applications of microeconomic mechanisms, with a revenue of about $72 billion in the US alone in 2016. However, the problem of designing the best economic mechanism for sponsored search auctions is far from being solved, and, given the amount at stake, it is no surprise that it has received growing attention over the past few years...

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...

Trans-species polymorphism, meaning the presence of alleles in different species that are more similar to each other than they are to alleles in the same species, has been found at loci associated with vegetative incompatibility in filamentous fungi. If individuals differ at one or more of these loci (termed het for heterokaryon), they cannot form stable heterokaryons after vegetative fusion. A...

We introduce anytime mechanisms for distributed optimization with self-interested agents. Anytime mechanisms retain good incentive properties even when interrupted before the optimal solution is computed, and provide better quality solutions when given additional time. Anytime mechanisms can solve easy instances of a hard problem quickly and optimally, while providing approximate solutions on v...

Video surveillance systems are critical infrastructures and that growing in size complexity. Storage space is the prime resource such but current setups centralized limited resources due to security cost constraints. Allocating correct amount of storage each camera considering their large differences characteristics video content challenging. In this paper we propose a game theoretic approach a...

Autonomic nervous system activity is essential for regulation of ventricular repolarization (VR) and plays an important role in several arrhythmogenic conditions. This study in 31 healthy adult subjects (16 men, 15 women) evaluated the VR response to pharmacologically modulated autonomic nervous system activity applying vectorcardiography (VCG) analysis. During continuous VCG recording, 0.01-0....

As Internet of Things technologies are increasingly being deployed, situations frequently arise where multiple stakeholders must reconcile preferences to control a shared resource. We perform five-month long experiment dubbed “smartSDH” (carried out in 27 employees’ office space) users report their for the brightness overhead lighting. smartSDH implements modified Vickrey–Clarke–Groves (VCG) me...

A boycott is a protest or a demand for change based on consumers following a simple rule: do not purchase service or goods from specific producers. In any network, and especially in the Internet, such grass-roots protest is close to impossible. The big networks do not connect directly to consumers and routing is based on locally choosing the shortest, cheapest, or most profitable paths. In this...
