A Ho:YLF laser pumped HBr molecular laser was developed that produced up to 2.5 mJ of energy in the 4 micron wavelength region. The Ho:YLF laser was fiber pumped using a commercial Tm:fibre laser. The Ho:YLF laser was operated in a single longitudinal mode via injection seeding with a narrow band diode laser which in turn was locked to one of the HBr transitions. The behavior of the HBr laser w...

Solving consensus in wireless ad hoc networks has started to be addressed in several papers. Most of these papers adopt system models developed for wired networks. These models are focused towards node failures while ignoring link failures, and thus are poorly suited for wireless ad hoc networks. The HO model, which was proposed recently, does not have this drawback. The paper shows that an exi...

BACKGROUND Norwegian government white papers have stated that the Sami population is reluctant to seek help from healthcare services and has traditions of self-help and the use of local networks. OBJECTIVE In this article we explore healthcare professionals' discursive constructions of Sami persons with dementia and their families' reluctance to seek and accept help from healthcare services. ...

The rapid expansion of mobile communications over the last few years allows the users to communicate without geographical coverage limitations of individual communication systems such as WLAN and WiMAX. In order to achieve interworking of Internet with wireless networks and to meet the requirement of seamless HO for real time and multimedia applications, mobility management needs careful attent...

Thirteen consultant neurologists working in ten different towns or cities in the United Kingdom were asked to log all their encounters with patients in 1 week. The median number of encounters was 79 (range 33-144). Forty-one per cent were new patients; 85% of all new patient encounters were with National Health Service patients. In more than four-fifths of all encounters, the neurologist felt t...

Management of insomnia rose significantly by age, from 0.2% of encounters with patients aged <25 years to 2.7% with patients aged 75 years and over. Insomnia was significantly more likely to be managed for female patients (1.4%) than for males (1.1%). Female patients were therefore significantly over represented at insomnia encounters (66.0%) compared with total BEACH encounters (57.1%), as wer...

Complexes of (not) connected graphs, hypergraphs and their ho-mology appear in the construction of knot invariants given by V. Vassiliev V1, V2, V4]. In this paper we study the complexes of not i-connected k-hypergraphs on n vertices. We show that the complex of not 2-connected graphs has the homotopy type of a wedge of (n ? 2)! spheres of dimension 2n ? 5. This answers a question raised by Vas...

BACKGROUND Diarrheal diseases remain a major cause of mortality in Africa and worldwide. While the burden of rotavirus is well described, population-based rates of disease caused by norovirus, sapovirus, and astrovirus are lacking, particularly in developing countries. METHODS Data on diarrhea cases were collected through a population-based surveillance platform including healthcare encounter...
