Incorporating ecological information into image-based vegetation mapping remains a challenge. Much attention has been placed on the use of ancillary information layers in image classification (e.g. slope, aspect, elevation) in that they provide indirect links to information that is ecologically relevant to species distributions. The objective of this study was to assess the utility of incorpora...

Experimental results on the connection between meanE×B flows and coherent oscillations at the frequency of the geodesic acoustic mode (GAM) in the H-1 heliac are presented. An increase in the mean local radial electric field, Er , is correlated with the development of several coherent modes. As mean Er increases, spectral energy, which is mostly contained in coherent modes, grows. This is follo...

This paper reviews various global instabilities destabilized by tangential neutral beam injection (NBI) in the Large Helical Device (LHD) plasmas. These global modes are toroidal Alfvén eigenmodes (TAEs), which are also observed in tokamak plasmas, and helicity-induced Alfvén eigenmodes (HAEs) which are observed only in three-dimensional plasmas such as LHD plasmas. Moreover, reversed magnetic ...

Cells dissociated from embryonic chick muscle tissue using trypsin were rotated in the presence of globulin-enriched rabbit antisera against both smooth and striated muscle actomyosins originating from chicken gizzard (GAM) and pectoralis (PAM) muscles respectively. The presence of the rabbit antibodies was demonstrated using peroxidase-labelled sheep antirabbit y-globulins, the enzyme-antibody...

“ It’s an outrage,” commented senior Paul Cromwick. “ Roemer knows so little about student psychology and co llege p re s ­ su res .” • “ This is something that will anger people,” Cromwick warned. Senior Michael Duffy cited an example of alcohol-related abuse at the Georgia Tech game. “ The last game, someone with sloe gin started throwing the liquor around in the stands. He drenched several g...

In 2002, methodological issues around time series analyses of air pollution and health attracted the attention of the scientific community, policy makers, the press, and the diverse stakeholders concerned with air pollution. As the Environmental Protection Agency (EPA) was finalizing its most recent review of epidemiological evidence on particulate matter air pollution (PM), statisticians and e...

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...
