Sediment transport is a complex, multi-dimensional process. With the advancement in computing power and sophistication of computer applications over recent decades, it has become possible to conduct detailed analysis and simulations of soil erosion and sediment transport. The primary objective of this study was to examine and predict the potential influence of human activities on sediment transport.

The research presented here aims to determine the influence of innate lateral spatial biases when driving. Data from the Strategic Highway Research Program Naturalistic Driving Study (SHRP 2 NDS) and a driving simulation were used to address our research questions.

Designers may use computational saliency models to predict how a viewer's attention will be guided by a specific effect; however, although saliency models provide a foundational understanding of emphasis perception, they only cover specific visual effects in abstract conditions. To address these limitations, we carried out crowdsourced studies that evaluate emphasis perception in a wider range of conditions than previously studied.

Similar to many crops, , an internationally important oilseed crop, suffers from low genetic diversity, and will require exploitation of diverse genetic resources to develop locally adapted, high yielding and stress resistant cultivars. A pilot study was completed to assess the feasibility of using indoor high-throughput phenotyping (HTP), semi-automated image processing, and machine learning to capture the phenotypic diversity of agronomically important traits in a diverse breeding population, SKBnNAM, introduced here for the first time.

This is largely owing to the size and complexity of the wheat genome, and the lack of genome-assembly data for multiple wheat lines.

However, individuals with a native reading direction other than left-to-right (LTR) show an attenuation of the leftward bias. The current study used procedurally similar tasks to examine spatial ability and aesthetic preferences in LTR and right-to-left (RTL) groups.

Diabetes can be stressful as parents seek optimal outcomes for their adolescent with type 1 diabetes. This study examined parents' interest and perspectives related to online diabetes resources. Based on a qualitative description approach, 14 qualitative group interviews were conducted with (i) parents of adolescents with diabetes (n = 29), and (ii) pediatric health care providers (n = 31).

The left bias appears to be stronger in the lower visual field during free-viewing, which could result from preferential dorsal stream processing. The current experiments used modified greyscales tasks, incorporating motion and isoluminant color, to explore whether targeting dorsal or ventral stream processing influenced the strength of the left bias.
View Article and Find Full Text PDFNeurologically normal people tend to collide with objects on the right side more frequently than with objects located on the left side of space. This phenomenon could be attributable to pseudoneglect wherein individuals selectively attend to the left field. The current study investigated this effect using a virtual route-following task that was presented centrally, in the lower field, and in the upper field.

This makes communication and information sharing difficult, and workers are often unable to account for others' activities when planning their own treatments. To address this issue, we developed and evaluated a clinical information system for home care that supports current paperwork practices and stores documents in a central repository that is accessible by all workers that treat a patient.

However, these tasks are confounded with proximity to the body, as fine motor tasks are performed proximally and aiming tasks are directed at distal targets. As such, it is not known whether the male advantage on tasks requiring aiming accuracy is because men have better aim or is better in the proximal domain in which the task is usually presented.

In home care, workers from different disciplines treat patients in their homes. However, workers who treat a shared patient are mobile and rarely see each other face-to-face, so it is difficult for them to maintain awareness of others' activities. In this paper, we discuss one aspect of these information limitations by considering how limited awareness of others' schedules influences work patterns in home care.

This study used a computerized adaptation of the game Concentration to test object location memory in both a static and dynamic array of 24 pairs of line drawings.
