Analyzing a large sample of Italian firms we find that the probability of default increases with size. This contrasts with the common observation, based on measures of exit from business registry data, that firms’ death rate is inversely related to the scale of their operation and suggests a rethinking of the economic role of larger companies. We gratefully acknowledge financial support from MI...

Jonathan M. Borwein1, Xianfu Wang August 13, 1999 ABSTRACT. We prove a \typi al" subdi erentiability prin iple and apply it to a variety of omplete metri spa es of ontinuous fun tions on separable Bana h spa es; so as to obtain existen e of fun tions with maximal subdi erentials when ordered by in lusion. The relationship between ontinuous fun tions with maximal subdi erentials and nowhere mono...

Gold(I)-catalyzed allene-vinylcyclopropane cycloisomerization leads to the tricyclic framework of the protoilludanes in a single step by a reaction that involves a cyclopropane ring expansion and a Prins cyclization.

Prins cyclization between a homoallylic alcohol and an aldehyde, promoted by trimethylsilyl halide, afforded 4-halo-tetrahydropyrans with good to excellent yields. Thanks to the absence of the solvent and metal, the THP thus obtained have been implicated without purification in several other reactions, in a sequential way, affording in particular new indole derivatives.

E- and Z-9-Methyldeca-3,8-dien-1-ols undergo smooth cyclization with aldehydes in the presence of 20 mol% AgSbF6 under extremely mild conditions to generate the corresponding oxa-bicycles in good yields with excellent selectivity. In fact, E-olefin affords the trans-product exclusively, whereas the Z-olefin gives the cis-product predominantly. In the case of E- or Z-8-methylnona-3,8-dien-1-ol, ...

In the paper, the possibility of joining Wireless Sensor Node and Cognitive Radio paradigms to obtain a new kind of Cognitive devices calledWireless Cognitive Sensor Nodes (WCSNs) will be considered. The paper will be focused on the design process of a sub-component of the WCSN: the Cognitive Antenna System. The architecture of WCSN together with the design process and antenna characteristics f...

A stereoselective approach to the 8b-azaacenaphthylene ring system is described. This new route features a dichloroketene-enol ether [2 + 2] cycloaddition, a vinylogous Mannich reaction, and an aza-Prins cyclization as key stereoselective transformations.

The iodine-catalyzed Prins cyclization of homoallylic alcohols and aldehydes was investigated under metal-free conditions and without additives. Anhydrous conditions and inert atmosphere are not required. The reaction of 2-(3,4-dihydronaphthalen-1-yl)propan-1-ol and 21 aldehydes (aliphatic and aromatic) in CH₂Cl₂ in the presence of 5 mol % of iodine gave 1,4,5,6-tetrahydro-2H-benzo[f]isochromen...
