We have obtained near-infrared spectra of the four brightest known Centaurs and of Ðve irregular satellites of giant planets. Many of these objects show 1.5 and 2.0 km absorption bands indicative of water ice, including 1997 Pholus, Phoebe (S9), and Nereid (N2). The satellites of JupiterÈElara, 26 Himalia, and Pasaphae (J6, J7, J8)Èappear spectrally featureless, consistent with asteroidal origi...

Chronic hepatitis C virus (HCV) infection is responsible for the development of liver cirrhosis and hepatocellular carcinoma. HCV core protein plays not only a structural role in the virion morphogenesis by encapsidating a virus RNA genome but also a non-structural role in HCV-induced pathogenesis by blocking innate immunity. Especially, it has been shown to regulate JAK-STAT signaling pathway ...

Hepatitis C virus (HCV) infection causes not only intrahepatic diseases but also extrahepatic manifestations, including metabolic disorders. Chronic HCV infection is often associated with type 2 diabetes. However, the precise mechanism underlying this association is still unclear. Glucose is transported into hepatocytes via glucose transporter 2 (GLUT2). Hepatocytes play a crucial role in maint...

Interior models of Jupiter and Saturn are calculated and compared in the framework of the three-layer assumption, which rely on the perception that both planets consist of three globally homogeneous regions: a dense core, a metallic hydrogen envelope, and a molecular hydrogen envelope. Within this framework, constraints on the core mass and abundance of heavy elements (i.e. elements other than ...

Geholaspis (Geholaspis) pennulatus sp. nov. is described from females and males collected from forest leaf litter in Northern Iran. The new species can be easily recognised by its barbed setae j2 and z1, dorsal shield seta j5 located posterior to j6 and z6, a very wide ventri-anal shield, and the shape of the epistome. Geholaspis (G.) comelicensis Lombardini, 1962 is considered as a junior syno...

In recent years a large theoretical and empirical literature has emerged on hysteresis in unemployment. This paper reviews the theoretical part of this literature, including the various insider-outsider models that have been advanced to explain hysteresis. The review finds that while the assumptions required to generate full hysteresis are somewhat extreme, a less severe form of hysteresis, cal...

This paper analyzes the determinants of homeownership in immigrant households over the 1980–2000 period. The study finds that immigrants have lower homeownership rates than natives and that the homeownership gap widened significantly during that period. The differential location decisions of immigrant and native households, as well as the changing national origin mix of the immigrant population...

Housing, Mobility and Unemployment ∗ This paper develops a model that shows why high-skilled workers move more and are therefore unemployed less than low-skilled workers. The model can explain the paradoxical empirical regularity that higher owner-occupation rates are associated with higher levels of unemployment although home-owners tend to be unemployed less. The choice of housing tenure affe...

Why Are European Countries Diverging in Their Unemployment Experience? During the nineties, unemployment has fallen in a number of European countries while it has remained high in others. The paper discusses potential causes for that evolution in light of recent economic research, emphasizing obstacles to reform due to political constraints, the prevalence of ideology, and agency issues within ...

Can Active Labor Market Policy Be Counter-Productive? We study active labor market policies (ALMP) in a matching model. ALMPs are modelled as a subsidy to job search. Workers differ in their productivity, and search takes place along an extensive margin. An additional job seeker affects the quality of unemployed workers. As a result, the Hosios conditions are no longer valid. To replicate the o...
