Melanie Taylor and colleagues discuss progress towards eliminating vertical transmission of HIV and syphilis.

A method is developed to quantify systematic errors in two types of sea surface temperature (SST) observations: bucket and engine-intake measurements. A simple linear model is proposed where the SST measured using a bucket is cooled or warmed by a fraction of the air–sea temperature difference and the SST measured using an engine intake has a constant bias. The model is applied to collocated ni...

Field observations of the incurred damages to the buildings and bridges due to earthquakes in near field show there are various failure modes which are in relation to the forces caused by vertical component. While vertical component of earthquake for ordinary buildings in most seismic regulations and standards is not considered. Therefore, in the current study the effects of vertical and horizo...

Marine dinoflagellate diel vertical migrations are often conceptually explained by a species' geotactic and phototactic preferences, but actual simultaneous measurements are rare. Newly collected simultaneous measurements on Heterocapsa (Cachonina) illdefina (Herman and Sweeney) and Gymnodinium breve (Davis) are combined with similar literature information on Amphidinium carterae (Hulbert), Per...

Let S = {l1, l2, l3, . . . , ln} be a set of n vertical line segments in the plane. Though not essential, to simplify proofs we assume that no two li’s are on the same vertical line. A convex polygon weakly intersects S if it contains a point of each line segment on its boundary or interior. In this paper, we propose an O(n log n) algorithm for the problem of finding a minimum area convex polyg...

This investigation demonstrated that the treatment protocol, "Cueing Verbs: A Treatment Strategy for Aphasic Adults" (hereafter referred to as CVT), was an effective rehabilitation technique. Specifically, this CVT was shown to be beneficial with marked/moderate to mild fluent aphasic adults. Additionally, the study addressed such issues as optimal treatment frequencies, treatment initiation an...

In two-dimensional Euclidean space, we examine behaviour of an arc when it crosses a vertical line. There are three types when an arc enters into a line, which are: “Left-In”, “Right-In” and “Oscillating-In”. Also, there are three types when an arc goes out from a line, which are: “Left-Out”, “Right-Out” and “Oscillating-Out”. If an arc is a special polygonal arc, there are only two types for e...

Pursuing new display techniques based on insights into human visual perception can reveal new possibilities for visual information devices. Here, we propose a novel information presentation technique that exploits the perceptional features during rapid eye movements called saccades by using a fast remote eye-measuring method. When light sources are fixed on a vertical line, and the flashing pat...

Abstract Fiber optic sensing has gained importance for wellbore monitoring and reservoir characterization in geothermal fields as it allows continuous, spatially highly resolved measurements. Distributed acoustic (DAS) distributed temperature (DTS) technologies, among others, enable of flow regimes heat transport inside the to describe dynamical behavior reservoir. The technically challenging i...
