The recent rise in a number of calamities and terrorist acts has brought much attention to the vulnerabilities of supply chains. Having passed through many hands that span continents and entities, the reliability and timeliness of freight delivery become increasingly difficult to be assessed. Particularly, at seaports which is an indispensible node in global supply chains and where complex sea ...

In the spirit of collaborative research, Glicken and Ford embarked on the problem of identifying the source of volcanic ash used as temper in prehistoric Maya ceramics. Verification of the presence of glass shards and associated volcanic mineralogy in thin sections of Maya ceramics was straightforward and pointed to the Guatemala Highland volcanic chain. Considering seasonal wind rose patterns,...

Patients with keratotic lesions distributed in a unilateral, linear, zosteriform or localized pattern and revealing histopathologic features of dyskeratotic acantholysis have been reported previously. There is some controversy in the appropriate nosologic classification of this entity. Some authors consider it as a localized form of Darier’s disease while others place it as a variant of e...

In this paper, we present an algebraic construction of tail-biting trellises. The proposed method is based on the state space expressions, i.e., the state space is the image of the set of information sequences under the associated state matrix. Then combining with the homomorphism theorem, an algebraic trellis construction is obtained. We show that a tailbiting trellis constructed based on the ...

Causal reasoning involves evaluation and integration of the observed evidence, the quality of which is influenced by the external factors such as uncertainty and the internal factors such as one’s cognitive ability. The current experimental study investigated the relationship between working memory (WM), causal reasoning and impacts of ambiguous observations. Results revealed that WM assessed b...

Human beings gesture everyday while speaking: they move their hands, their heads, their arms; their whole body is involved in communication. But how does it work? How do we produce gestures and in what purpose? How are gestures connected to speech? When do we begin producing gestures and how do they evolve throughout the life span? These are questions gesture researchers have been trying to ans...

We built an artificial market model and compared effects of price variation limits, short selling regulations and up-tick rules. In the case without the regulations, the price fell to below a fundamental value when an economic crush occurred. On the other hand, in the case with the regulations, this overshooting did not occur. However, the short selling regulation and the up-tick rule caused th...

This issue presents a snapshot of Musical Research at Ircam between 2008 and 2011, following the very first issue of this journal in 1984 on Musical Thought at IRCAM (Tod Machover, Editor). Within this time span, whereas the role of Ircam as an institution dedicated to scientific research for artistic creativity has remained unchanged, the context of such innovative endeavors, the role of the i...
