Increase in competition level and unclear demand in the market have made organizations to utilize scientific models and techniques for optimizing their management process. Among the main processes effective on organizations performance is to select appropriate providers. The following research tries to present an optimized solution for providers, assessment and selection. The study uses data en...

with the ultimate theory error below percent level [2]. This sets high standards for the determinations of the other two angles, α = arg(−V ∗ tbVtd/V ∗ ubVud) and γ = arg(−V ∗ ubVud/V ∗ cbVcd). In this review we address the theoretical errors for the methods that are used in the determination of α. They represent the ultimate precision at which the angle α can be measured even with unlimited st...

We propose a variant of the heterodyne holography scheme that combines the properties of off-axis and phase-shifting holography. This scheme makes it possible to filter off numerically the zero-order image alias and the technical noise of the reference. It is then possible to record and reconstruct holographic images at an extremely low signal level. We show experimentally that the sensitivity ...

A code called UNÌC is currently under development at Argonne National Laboratory (ANL). The aim of the code is to provide a neutronic solver with the same geometrical flexibility of Monte Carlo codes and without the approximations (homogenization and energy condensation) associated with the common multi-step approach currently used. Moreover, UNÌC will offer the capability of multi-resolution i...

Andy Clark has argued that language is “in many ways the ultimate artifact” (Clark 1997, p.218). Fuelling this conclusion is a view according to which the human brain is essentially no more than a patterncompleting device, while language is an external resource which is adaptively fitted to the human brain in such a way that it enables that brain to exceed its unaided (pattern-completing) cogni...

The performance of metal microelectrodes for stimulating and recording neuronal action potentials depends on precise control of their geometrical, electrical and mechanical properties. We describe a combination of materials whose properties approach fundamental physical limitations on achievable performance and reproducible fabrication techniques that provide probes with very small dimensions. ...

The ultimate regime of thermal convection, the so-called Kraichnan regime [R. H. Kraichnan, Phys. Fluids 5, 1374 (1962)]], hitherto has been elusive. Here numerical evidence for that regime is presented by performing simulations of the bulk of turbulence only, eliminating the thermal and kinetic boundary layers and replacing them with periodic boundary conditions.

Fibrotic disorders account for an increasing burden of disease-associated morbidity and mortality worldwide. Although numerous risk factors have been recognized, the etiologies of many of these clinical syndromes have not been identified, and they are often termed idiopathic or cryptogenic. Here, we provide an evolutionary perspective on fibrosis aimed at elucidating its etiopathogenesis. By as...
