EXPOSURE ASSESSMENT OF PRIORITY PAHS FOR EMPLOYEES OF ENTERPRISES

open access: yesRUDN Journal of Ecology and Life Safety, 2015
Priority PAHs concentrations in the ambient air, working zone air and food products were measured by the mean of mass spectrometry. Data on the content of PAHs including benz(a)pyrene were used for exposure assessment of priority PAHs for employees of ...

Regional governance in unitary states

open access: yesLocal Government Studies, 2005
There is a growing need for regional governance in Western European countries. Unitary states and nations like the Netherlands, France and England do not (yet) have fully fledged, general purpose intermediate governments that can fulfil this need. This article reviews the institutional arrangements for regional governance in the countries mentioned ...

Impact of small‐scale gravity waves on tracer transport

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.

Accreditation Against Limited Adversarial Noise

open access: yesAdvanced Quantum Technologies, EarlyView.
An upgraded accreditation (a variant of quantum verification) scheme is presented, significantly relaxing the assumptions, to allow adversarial noise, while preserving the suitability for near‐term / immediate usage. Abstract An accreditation protocol (a variety of quantum verification) is presented, where error is assumed to be adversarial (in ...

Simulating Quantum State Transfer Between Distributed Devices Using Noisy Interconnects

open access: yesAdvanced Quantum Technologies, EarlyView.
Noisy connections challenge future networked quantum computers. This work presents a practical method to address this by simulating an ideal state transfer over noisy interconnects. The approach reduces the high sampling cost of previous methods, an advantage that improves as interconnect quality gets better.

Blinking Optical Tweezers for Atom Rearrangements

open access: yesAdvanced Quantum Technologies, EarlyView.
The work introduces an energy‐efficient method for holding and rearranging an N ×$\times$ M array of atoms using only N optical tweezers, using just 1M of the optical power per atom. In the proof‐of‐concept experiments, single blinking tweezer holds M = 9 atoms and further facilitates rearrangement M = 4 ∼$\sim$ 5 atoms in various configurations ...
