Interim medication-only treatment has been suggested for the initiation of opioid maintenance treatment (OMT) in opioid-dependent subjects, but this rarely has been studied using buprenorphine instead of methadone. Following a pilot trial assessing interim buprenorphine-naloxone treatment in order to facilitate transfer into OMT, we here aimed to study retention, and potential correlates of ret...

This paper describes a channel estimation and tracking scheme for OFDM MIMO systems based on pilot tones. The mean square error of the proposed scheme is derived, and through this we derive optimal training sequences and placement of the pilot tones. It is shown in this paper that minimum mean square (MMSE) channel estimation is obtained with equipowered, equispaced, orthogonal and phase shift ...

We study a multi-cell multi-user MIMO full-duplex network, where each base station (BS) has multiple antennas with full-duplex capability supporting single-antenna users with either full-duplex or half-duplex radios. We characterize the upand downlink ergodic achievable rates for the case of linear precoders and receivers. The rate analysis includes practical constraints such as imperfect selfi...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the Western Atlantic: the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to identify to the species level at sea; therefore, some of the descriptive material below refers to Globicephala sp. and is identified as such. The specie...

STOCK DEFINITION AND GEOGRAPHIC RANGE The short-finned pilot whale is distributed worldwide in tropical to warm temperate waters (Leatherwood and Reeves 1983). There are two species of pilot whales in the western North Atlantic the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to differentiate at sea; the...

In this paper we report on full C-band tunable, 10 Gbit/s capability, directly modulated micro-electromechanical system (MEMS) vertical-cavity surface-emitting laser (VCSEL) for next generation converged mobile fronthaul and backhaul applications, where the MEMS-VCSEL is used at the remote side of a wavelength routed WDM-PON system. To be compliant with the current ITU-T G.metro standardization...

Cosmic shear offers a remarkbly clean way to measure the equation of state of the Universe and its evolution. Resolution over a wide field is paramount, and Antarctica offers unique possibilities in this respect. There is an order of magnitude gain in speed over temperate sites, or a factor three in surface density. This means that PILOT outperforms much larger telescopes elsewhere, and can com...

PILOT, the Pathfinder for an International Large Optical Telescope, is proposed as a 2.4 m diameter optical/infrared telescope to be located at Dome C, Antarctica. The “strawman” optical configuration and instrument suite for PILOT described here is designed to take advantage of the unique atmospheric characteristics found at this site.

BACKGROUND In rural health and other health service development contexts, there is frustration with a reliance on pilot projects as a means of informing policy and service innovation. There is also an emerging recognition that existing research methods do not draw lessons from the failed sustainability that characterises many of these pilots and demonstration projects. DISCUSSION This article...

We describe the implementation of a pilot project to demonstrate the safety and feasibility of providing PrePex circumcision from a mobile clinic. We analyzed available project diary entries and staff meeting minutes to identify challenges encountered. The main challenges identified were (1) daily time constraints because of setting up procedures, (2) transportation logistics for clients when t...
