1 2 Understanding the habitat requirements of a species for breeding is essential for its 3 conservation, particularly if the availability of suitable habitat is a limiting factor for 4 population growth. This is postulated to be the case for grey seals, one of the more 5 abundant marine apex predators in northern European waters. In common with similar 6 studies that have investigated the habi...

OBJECTIVE Prevalence of acute malnutrition is classically estimated by the proportion of children meeting a case definition in a representative population sample. In 1995 the WHO proposed the PROBIT method, based on converting parameters of a normally distributed variable to cumulative probability, as an alternative method requiring a smaller sample size. The present study compares classical an...

This paper addresses two concerns with the state of the art in network revenue management with dependent demands. The first concern is that the basic attraction model (BAM), of which the multinomial model (MNL) is a special case, tends to be too optimistic in estimating demand spill. The second concern is that the choice based deterministic linear program (CBLP) currently in use to derive heuri...

The paper presents a Generalized Aggregation Multilevel (GAM) solver, which automatically constructs nearly optimal auxiliary coarse models based on the information available in the source grid only. GAM solver is a hybrid solution scheme where approximation space of each aggregate (group of neighboring elements) is adaptively and automatically selected depending on the spectral characteristics...

This paper addresses two concerns with the state of the art in network revenue management with dependent demands. The first concern is that the basic attraction model (BAM), of which the multinomial model (MNL) is a special case, may overestimate recapture in certain cases. The second concern is that the choice based deterministic linear program (CBLP), currently in use to derive heuristics for...

The genus Agathodesmus Silvestri, 1910 is speciose and widespread in high-rainfall parts of eastern Australia. In addition to the type species Agathodesmus steeli Silvestri, 1910 and Agathodesmus johnsi Mesibov, 2009 from New South Wales and Agathodesmus bucculentus (Jeekel, 1986) from Queensland, the following 18 new species are recognised: Agathodesmus adelphus sp. n., Agathodesmus aenigmatic...

Background A novel approach for improving community case-detection of acute malnutrition involves mothers/caregivers screening their children for acute malnutrition using a mid-upper arm circumference (MUAC) insertion tape. The objective of this study was to test three simple MUAC classification devices to determine whether they improved the sensitivity of mothers/caregivers at detecting acute ...

Drift wave turbulence is known to self-organize to form axisymmetric macroscopic flows. The basic mechanism for macroscopic flow generation is called inverse energy cascade. Essentially, it is an energy transfer from the short wavelengths to the long wavelengths in the turbulent spectrum due to nonlinear interactions. A class of macroscopic flows, the poloidally symmetric zonal flows, is widely...

We report purification of an 18-kDa heparin-binding growth factor secreted from human cancer cells which is homologous to a developmentally regulated, neurotrophic factor, heparin-binding growth-associated molecule/pleiotrophin (HB-GAM/PTN; Merenmies, J., and Rauvala, H.
