This work presents an alternative wearable tracking system based on a low-power wide area network. A complete GPS receiver was integrated with a textile substrate, and the latitude and longitude coordinates were sent to the cloud by means of the SIM-less SIGFOX network. To send the coordinates over SIGFOX protocol, a specific codification algorithm was used and a customized UHF antenna on jeans...

Explaining large-scale patterns of variation in body size has been considered a central question in ecology and evolutionary biology because several life-history traits are directly linked to body size. For ectothermic organisms, little is known about what processes influence geographic variation in body size. Changes in body size and sexual size dimorphism (SSD) have been associated with envir...

Feeding damage by larval coneworms (Lepidoptera: Pyralidae) on flowers and cones of pines can cause significant economic losses in pine seed orchards in the southern USA (Ebel et al. 1980, USDA Forest Service GTR SE-8, Asheville, NC). The south coastal coneworm, Dioryctria ebeli Mutuura & Monroe, is a common pest in seed orchards of slash pine (Pinus elliottii L.) in the coastal region of south...

Apple scab emerged as an expensive problem in apple orchards throughout the Northeastern United States in 2009. Experienced growers who had managed scab effectively for many years found themselves spray ing throughout summer to control scab that kept appearing on new leaves. Th e effort required to protect fruit from scab during summer increased production costs and represents a “loss” to apple...

BACKGROUND Pediatric Crohn's disease (CD) is a lifelong, debilitating, and costly disease. In previous studies, CD incidence increased with higher geographic latitude in the Northern Hemisphere. This may indicate a role for lower vitamin D status as a risk factor for CD. Analysis of worldwide incidence of pediatric CD has not been previously reported. METHODS We undertook a systematic review ...

INTRODUCTION We estimated the prevalence of multiple sclerosis (MS) in 3 large geographic areas in the southern, middle, and northern United States. METHODS The primary data source was medical records from office visits to private neurologists' practices or to neurology departments in tertiary care facilities during a 3-year period. Additional data sources included patient advocacy groups, nu...

We studied the geographic variation of three morphometric characters in relation to body size in two South American grasshoppers (Acrididae), Dichroplus vittatus Bruner and D. pratensis Bruner to test Allen's rule in these ectotherms. Since both species follow the converse to Bergmann's rule owing to latitudinal and/or altitudinal variation in time available for growth and reproduction, geograp...

Schema: Many applications of knowledge discovery require the knowledge to be consistent with data. Examples include discovering rules for query optimization, database integration, decision support, etc. However, databases usually change over time and make machine-discovered knowledge inconsistent with data. Useful knowledge should be robust against database changes so that it is unlikely to bec...

To effectively prevent heavy metal pollution in water sources tourist attractions, clarify the degree of control sources, and improve accuracy tracing results, a GIS-based remote sensing method attractions is proposed. Using GIS spatial analysis method, DEM elevation data monitored by obtained, watershed geographic information compiled, GPS obtains longitude latitude coordinates to locate sourc...

Abstract Persistent warming and water cycle change due to anthropogenic climate modifies the temperature salinity distribution of ocean over time. This “forced” signal is often masked by background internal variability system. Analyzing in water-mass-based coordinate systems has been proposed as an alternative traditional Eulerian (e.g., fixed-depth, zonally averaged) systems. The impact though...
