Deciding what mix of engine and battery power to use is critical to hybrid vehicles' fuel efficiency. Current solutions consider several factors such as the charge of the battery and how efficient the engine operates at a given speed. Previous research has shown that by taking into account the future power requirements of the vehicle, a more efficient(More)
Grice characterized communication in terms of the cooperative principle, which enjoins speakers to make only contributions that serve the evolving conversational goals. We show that the cooperative principle and the associated maxims of relevance, quality, and quantity emerge from multi-agent decision theory. We utilize the Decentralized Partially(More)
Conversational implicatures involve reasoning about multiply nested belief structures. This complexity poses significant challenges for computational models of conversation and cognition. We show that agents in the multi-agent Decentralized-POMDP reach implicature-rich interpretations simply as a by-product of the way they reason about each other to(More)
BACKGROUND Vascular anomalies are vascular tumors and congenital malformations that rarely involve the pancreas. Diagnosis and management of these lesions is complex. METHODS An institutional review board-approved retrospective database and record review from 1994 through 2004 at a quaternary referral center for vascular anomalies was conducted. RESULTS(More)
Online marketplaces increasingly act as intermediaries in labor, housing, dating, and other markets where traders match with each other. These marketplaces use novel data generated by users' activities on the website to design algorithms and products that influence the search and matching process. I use internal data from Airbnb, a prominent online(More)
Recursive Bayesian models of linguistic communication capture a variety of intricate kinds of pragmatic enrichment, but they tend to depend on the unrealistic assumption that agents are invariably optimal reasoners. We present a discrimina-tive model that seeks to capitalize on the insights of such approaches while addressing these concerns about(More)
Cutis marmorata telangiectatica congenita (CMTC) is a rare congenital disorder. We describe an 8-year-old boy with CMTC who presented with symptomatic claudication and diminished distal pulses. Imaging showed severe stenosis of the right common iliac artery, and the child underwent uncomplicated ilio-iliac bypass using prosthetic graft. This is the first(More)
BACKGROUND/PURPOSE Sclerotherapy for vascular malformations is often limited by luminal recanalization. This study examined whether an injectable tissue-engineered construct could prevent this complication in a rabbit model of venous sclerotherapy. METHODS Ethanol sclerotherapy of a temporarily occluded jugular vein segment was performed in 46 rabbits,(More)
