A calculational procedure is formulated for extracting differential cross sections in the ejected energy from a time-dependent wave-packet method for the electron ionization of hydrogen. The procedure is applied to an s-wave model for electron-hydrogen scattering. In contrast to recent time-independent methods, the differential cross sections are found to be smooth and symmetric. @S1050-2947~97...

OBJECTIVES This paper aimed to employ subject matter experts (SMEs) to assess the extent to which the Korean version of the short-form of the OHIP (OHIP-14 K) is culturally valid and equivalent in Korean. METHODS We approached 17 bilingual Korean SMEs from which 10 independently rated the clarity, relevance, and cultural equivalence of the OHIP-14 K. SME's varied between 10 and 41 years of cl...

The first health impact assessment (HIA) performed on a high level local government policy in New Zealand was undertaken on the Greater Christchurch Urban Development Strategy in 2005. This report describes its development and implementation and the results from the process evaluation including some recommendations made in the assessment. We concluded that HIA is a useful tool for local governm...

This work describes the application of hydrodynamic (ELCIRC) and transport (VELA and VELApart) models to the Ria Formosa lagoon (Portugal) to study the impact of the relocation of the Ancão Inlet. Located in the south of Portugal, this lagoon is a mesotidal barrier island system that communicates with the sea through 6 inlets. The Old Ancão Inlet was artificially closed and the New Ancão Inlet ...

BACKGROUND In idiopathic adult hydrocephalus syndrome (IAHS), a pathophysiological model of "chronic ischaemia" caused by an arteriosclerotic process in association with a CSF hydrodynamic disturbance has been proposed. OBJECTIVE To investigate whether CSF hydrodynamic manipulation has an impact on biochemical markers related to ischaemia, brain tissue oxygen tension (PtiO(2)), and intracrani...

This work presents the investigation of hydrodynamic filling of beads into flat microfluidic devices. A periodical hexagonal monolayer as aggregation pattern is favorable for parallel optical detection. Several microfluidic devices for bead-based analyses were designed. Each microfluidic device consists of one inlet channel, one flat aggregation chamber for the beads and several outlet channels...

A framework of analogy between wiretap channels (WTCs) and state-dependent point-to-point channels with noncausal encoder channel state information (referred to as Gelfand-Pinker channels (GPCs)) is proposed. A good (reliable and secure) sequence of wiretap codes is shown to induce a good (reliable) sequence of codes for a corresponding GPC. Consequently, the framework enables exploiting existi...

A new approach extracting multi-parametric hydrodynamic reductions for the integrable hydrodynamic chains is presented. The Benney hydrodynamic chain is considered.

Macroalgae use flexibility and reconfiguration, i.e. the alteration of shape, size and orientation as water velocity increases, to reduce the hydrodynamic forces imposed in the wave-swept rocky intertidal zone. Quantifying the effects of flexibility on hydrodynamic performance is difficult, however, because the mechanisms of reconfiguration vary with water velocity and the relationship between ...
