Background: Seasonality in suicide has been investigated from the early 19th century to explore the productive environmental variables. Seasonality studies can provide information on prevention and interventions in suicide. In this study, we examined seasonality in suicide and aimed to explore the differences in seasonality between rural and urban areas, mental disorders, and genders. Method...

Many applications in wireless sensor networks (WSNs) benefit significantly from organizing nodes into groups, called clusters, because data aggregation and data filtering applied in each cluster can greatly help to reduce traffic. The size of a cluster is measured by the hop distance from the farthest node to the cluster head. Rather than 1-hop clustering, K-hop clustering is preferred by many ...

A secure scheme for heterogeneous wireless sensor networks is presented. The wireless sensor networks have some sensor nodes and heterogeneous sensor nodes that have greater power and transmission capability than other nodes have. All kinds of sensor nodes are evenly distributed respectively in entire sensing area that is divided into a number of same cells and logical groups evenly. The pairwi...

Decreases in the glutathione peroxidase activity and in the selenium content were found in the plasma of pregnant women as compared with a control group. In the erythrocytes, both parameters remained unchanged. In both groups a fraction of about 0.90 of the glutathione peroxidase in the blood, was contained in the erythrocytes, whereas the selenium was nearly evenly distributed between plasma a...

A new type of pre-Descemet's corneal dystrophy is described. The opacities are punctiform, polychromatic, of uniform size, and evenly distributed over the whole cornea. The diagnosis is made only by slit lamp because there is no visual impairment. The disease is hereditary and follows the autosomal mode of inheritance with a high percentage of penetrance, expressivity, and specificity in 4 succ...

We describe a new pose estimation approach for a 3D object capture system. This 3D pose estimation approach offers several advantages: increased visibility, robustness to lighting conditions, and improved reliability with evenly distributed errors. The calibration pattern is built using 3D conic features. We use simplex search to find the camera position and orientations that minimizes the erro...

Despite continued growth of the primary care workforce, profound maldistribution persists among providers available for the care of children. Family physicians (FPs) spend, on average, approximately 10% of their total practice time caring for children; however, given that, among physician specialties, FPs are geographically distributed most evenly across the US population, the self-reported dec...

We study the problem of evaluating conjunctive queries composed of triple patterns over RDF data stored in distributed hash tables. Our goal is to develop algorithms that scale to large amounts of RDF data, distribute the query processing load evenly and incur little network traffic. We present and evaluate two novel query processing algorithms with these possibly conflicting goals in mind. We ...

In this paper, distributed control policies for spacecraft formations that draw inspiration from the simple idea of cyclic pursuit are studied. First studied are cyclic-pursuit control laws for both singleand double-integrator models in three dimensions. In particular, control laws are developed that only require relative measurements of position and velocity with respect to the two leading nei...
