An expression for the radiation force from a cw-laser on a fluidfluid interface is derived that is able to model the giant deformations observed in modern experiments when the fluid system is close to the critical point implying that the surface tension is very small. The core of our argument is that the system is modelled as a step-index optical fiber. Then, observing that the dominant HE11 mo...

BACKGROUND From a health services perspective, peer-based resources merit special attention. Participation in self-help fellowships, like the Twelve Step Groups (TSGs), have been shown to improve outcomes of patients with substance use disorder (SUD) and they represent a valuable adjunct to the SUD treatment system. This study investigated the relationship between patient perceptions of TSGs an...

Aircraft noise is characterized by intermittent noise events which vary in number and level from day to day, from one season to another, and usually show a gradual increase of the number of flights and a gradual decrease of the LAeq from year to year. Since a real or expected step change in aircraft noise often causes strong change reactions in residential areas, which cannot be predicted by st...

Step change often occurs when worlds that do not normally interact begin to communicate with each other in ways in which collaboration replaces competition. An example of this, driven by U.S. national interests in maintaining predominance in semiconductor manufacturing, is a company called SEMATECH (SEmiconductor MAnufacturing TECHnology). SEMATECH may also be an example of how the public and p...

This article describes the collaborative innovation practices used by outsourcing clients and their suppliers, based on insights gained from 26 organizations with a mature sourcing capability drawn from Europe, the U.S., and Asia/Pacific. We present a collaborative innovation framework comprising the four practices (Leading, Contracting, Organizing, and Performing) that these client organizatio...

For a contravariant 4-metric which changes signature from Lorentzian to Riemannian across a spatial hypersurface, the mixed Einstein tensor is manifestly nonsingular. In Gaussian normal coordinates, the metric contains a step function and the Einstein tensor contains the Dirac delta function with support at the junction. The coefficient of the Dirac function is a linear combination of the secon...

Chemical Regulation and the means by which data is generated for the purposes of risk assessment is undergoing a tremendous shift. There is a strong impetus in Europe, in particular, to move towards non-animal approaches to address data gaps for specific endpoints either in lieu of testing or as part of weight of evidence approaches within integrated testing strategies (ITS). An Exposure assess...

'Health inequalities' are differences in health between different subgroups of a population 1 , for example women/men, people with/without disabilities, and urban/rural dwellers. Many of us have insufficient information to understand the nature and extent of the inequalities that exist, and whether our services are effective. This lack of information restricts our ability to plan appropriate st...
