The hallmarks of leukocyte adhesion deficiency (LAD) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. These molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. Over las...

Introduction: The restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. The aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. Methods: E...

There have been few studies to date describing fatigue-crack propagation thresholds under mixed-mode loading conditions in the presence of cracks, that are small as compared to the characteristic microstructural dimensions. To address this need, the variation in mixed-mode, high-cycle fatigue-crack growth thresholds with crack size is reported for a Ti-6Al-4V turbine blade alloy with a fine-gra...

We study the molecular-level properties of single-crystal ice Ih surface using interface-specific sum frequency generation spectroscopy. probe water vibrational bend region around 1650 cm–1 basal plane hexagonal to understand interfacial structure from properties. As opposed stretch mode ice, bending response depends very weakly on temperature. The large line width response, relative water, is ...

Velocity fields and density fluctuations of edge turbulence are studied in I-mode [F. Ryter et al., Plasma Phys. Controlled Fusion 40, 725 (1998)] plasmas of the Alcator C-Mod [I. H. Hutchinson et al., Phys. Plasmas 1, 1511 (1994)] tokamak, which are characterized by a strong thermal transport barrier in the edge while providing little or no barrier to the transport of both bulk and impurity pa...

The search for primordial gravitational waves through the $B$-mode polarization pattern in CMB is one of major goals current and future experiments. Besides foregrounds, a potential hurdle this anisotropic secondary generated by scattering photons off free electrons produced during patchy cosmological reionization. Robust predictions these anisotropies are challenging because uncertainties reio...

Abstract We present a theory of turbulence elasticity, which follows from delayed response of drift waves (DWs) to zonal flow (ZF) shears. It is shown that when |hV iZF |/ !k > 1, with |hV iZF | the ZF shearing rate and !k the local turbulence decorrelation rate, the ZF evolution equation is converted from a di↵usion equation to a telegraph equation. This insight provides a natural framework fo...

in this paper we consider the non-preemptive variant of a multi-mode resource constrained project scheduling problem (mrcpsp) with mode identity, in which a set of project activities is partitioned into disjoint subsets while all activities forming one subset have to be processed in the same mode. we present a depth-first branch and bound algorithm for the resource constrained project schedulin...
