This paper provides theoretical bounds for empirical game theoretical analysis of complex multi-agent interactions. We provide insights in the empirical meta game showing that a Nash equilibrium of the meta-game is an approximate Nash equilibrium of the true underlying game. We investigate and show how many data samples are required to obtain a close enough approximation of the underlying game....

In this paper, we present a semantic role labeler (or chunker) that groups syntactic chunks (i.e. base phrases) into the arguments of a predicate. This is accomplished by casting the semantic labeling as the classification of syntactic chunks (e.g. NP-chunk, PP-chunk) into one of several classes such as the beginning of an argument (B-ARG), inside an argument (I-ARG) and outside an argument (O)...

This paper utilizes Yamcha, a SVM tool designed by Taku Kudo, to train an NP-chunking model for Chinese. In addition to IOB and two words surrounding the focused word, we experimented on new features and exploited unlabeled data from web pages to enhance the previous model. Our experiments with supervised learning indicate that our chosen feature sets outperform those reported in previous studi...

We present an efficient framework to estimate the rule probabilities for a hierarchical phrasebased statistical machine translation system from parallel data. In previous work, this was done with bilingual parsing. We use a more efficient approach splitting the bilingual parsing into two stages, which allows us to train a hierarchical translation model on larger tasks. Furthermore, we apply lea...

treatment of a tuberculous aneurysm of the descending thoracic aorta in a young patient. A 28-year old male patient was diagnosed with a mycotic aortic tuberculous aneurysm (Fig. 1A) and a thoracic endoprosthesis was implanted. An additional 6-month course of tuberculostatic drugs was completed. After 24 months of follow-up, the patient remains asymptomatic with no evidence of infection recurre...

We present a mechanism able to show intrinsic bistable behaviour involving single Y b ions embedded into bromide lattices, in which intrinsic optical bistability (IOB) has been observed. The mechanism is based on the experimentally found coupling between the Y b ion and the totally symmetric local mode of vibration of the [Y bBr6] 3− coordination unit. The model reproduces the IOB observed in C...

Endovascular technologies are rapidly evolving, often requiring coordination and cooperation between clinicians and technicians from diverse specialties. These multidisciplinary interactions lead to challenges that are reflected in the high rate of errors occurring during endovascular procedures. Endovascular virtual reality (VR) simulation has evolved from simple benchtop devices to full physi...

Carotid-cavernous fistulas (CCFs) pose an anatomically and physiologically challenging problem for clinicians. The most common method of treatment for these lesions is transvenous endovascular embolization via the inferior petrosal sinus or the facial vein. When transvenous access is not possible, an alternate approach must be devised. We describe a case example with bilateral Barrow Type B CCF...

In this paper we study the splitting of separatrices phenomenon which arises when one considers a Hamiltonian System of one degree of freedom with a fast periodic or quasiperiodic and meromorphic in the state variables perturbation. The obtained results are different from the previous ones in the literature, which mainly assume algebraic or trigonometric polynomial dependence on the state varia...

the aim of this paper is to study orders over a valuation ring v with arbitrary rank in acentral simple f-algebra q. the relation between all of the orders is explained with a diagram. it is thenshown that inside bezout order, extremal v-orders are precisely semi-hereditary. in the last section, theeffect of henselization on maximal and semi-hereditary orders is examined.
