The mechanisms driving the spatial patterns of species richness and composition are essential to the understanding of biodiversity. Numerous studies separately identify the contributions of the environment (niche process) and space (neutral process) to the species richness or composition at different scales, but few studies have investigated the contributions of both types of processes in the t...

We investigate the structure of positions obtained by turning the Skewb. These ‘legal’ positions are singled out among the positions obtained by disassembling and arbitrarily reassembling the Skewb. The set of legal positions is modelled as a group, the ‘Skewb group’, that is characterised as the kernel of a group homomorphism. Also, the Skewb group is shown to be isomorphic to a group of known...

We investigated the diversity and community composition of denitrifying bacteria in surface water from the Yellow River estuary. Our results indicated that the diversity of the denitrifying community in freshwater based on the nirK gene was higher than that in seawater. Furthermore, phylogenetic analysis suggested that the bacteria community could be distributed into eight clusters (Clusters I ...

BACKGROUND The purpose of this study was to classify patterns of instrumental activities of daily living (IADL) among community-dwelling older women, to examine difference in characteristics among the classes, and to explore predictors of class membership. METHODS This study was a secondary analysis of nationwide data from the 2014 Actual Living Condition of the Elderly and Welfare Need Surve...

OBJECTIVE To assess the functional capacity and to determine the difference between the means of functional capacity (basic and instrumental activities of daily living) and the age groups of elderly residents in an outlying area in the hinterland of Bahia/Northeast of Brazil. METHOD Analytical study with cross-sectional design and a sample of 150 elderly individuals enrolled in four Health Un...

[Purpose] The newly developed Functional Independence and Difficulty Scale is a tool for assessing the performance of basic activities of daily living in terms of both independence and difficulty. The aim of this study was to examine the predictive validity of the scale for decline of instrumental activities of daily living ability and multiple falls during a 24-month follow-up period. [Subject...

AIMS AND OBJECTIVES This study aimed to test feasibility of a home-based sensor system that is designed to assess mobility and daily activity patterns among Korean American older adults (KAOAs; n = 6) and explore sensor technology acceptance among participants. BACKGROUND Home-based sensors have the potential to support older adults' desire to remain at home as long as possible. Despite a gro...
