Extensive urbanization has greatly raised the demand for cleaner coal- and petroleum-derived fuels. Mainly composed of methane, natural gas represents a promising alternative for this purpose, making its storage a significant topic. In the present research, deposition of methane molecules in C60 fullerene was investigated through a combined approach wherein density functional based tight bindin...

Peripheral nerve injury requires a long recovery period, and recovery, once attained, usually is incomplete. Inflammatory procedures may inhibit functional recovery after nerve injury and produce cell death in both the central nervous system and the peripheral nervous system. Since the glycyrrhiza glabra extract has anti-inflammatory effects, it could reduce the severity of injury. The aim of t...

0. Proposal. A central debate in the study of phrase structure concerns the nature of functional projections which dominate lexical ones. At one extreme is the position, advocated by Cinque (1999, 2002), that grammars employ a universal set of functional categories and that their number and relative order is the same across languages, regardless of properties of the lexical head. At the other e...

Cortico-cortical projections for visual processing that originate from the striate cortex are organized into two streams. The dorsal stream projects to the parietal region and the ventral stream to the inferior temporal region. One hypothesis is that the dorsal stream processes visual spatial information, and the ventral stream processes visual object information. Although recognition of human ...

Covariance operators of random functions are crucial tools to study the way random elements concentrate over their support. The principal component analysis of a random function X is well-known from a theoretical viewpoint and extensively used in practical situations. In this work we focus on local covariance operators. They provide some pieces of information about the distribution of X around ...

Pulmonary bullae usually occur as isolated abnormalities in otherwise normal lung tissue or, more frequently, in the presence of emphysema. Pulmonary bullae tend to progressively increase in their size, and spontaneous regressions have very rarely been reported. In this paper, we report the case of an older woman experiencing the spontaneous resolution of a giant pulmonary bulla. Interestingly,...

We show how Wadler and Hughes's use of Scott projections to describe properties of functions (\Projections for Strictness Analysis", FPCA 1987) can be generalised by the use of partial equivalence relations. We describe an analysis (in the form of an abstract interpretation) for identifying such properties for functions deened in the simply typed-calculus. Our analysis has a very simple proof o...

It has been noticed long ago that many results on sections and projections are dual to each other, though methods used in the proofs are quite different and don't use the duality of underlying structures directly. In the paper [KRZ], the authors attempted to start a unified approach connecting sections and projections, which may eventually explain these mysterious connections. The idea is to us...

This paper examines the link between multinational enterprises and plant exit in Chile. We investigate three main questions: are affiliates of foreign multinationals more likely to exit than domestic firms? Does the exit probability of multinationals depend on its export orientation?, and Does the presence of multinationals affect the survival of other firms in the economy? Our results show tha...
