Background The purpose of this study is to compare the diagnostic value, imaging quality and apparent diffusion coefficient (ADC) value of reduced field-of-view diffusion-weight imaging (r-FOV DWI) and full field-of-view diffusion-weight imaging (f-FOV ...

The Atacama Desert, the oldest and driest desert on Earth, displays significant rains only once per decade. To investigate how microbial communities take advantage of these sporadic wet events, we carried out a geomicrobiological study a few days after a

Three Dimensional Nonlinear Guidance Law for Exact Impact Time Control
This paper presents a nonlinear guidance law for controlling the impact time of a missile-target engagement in three dimensions. The guidance law is initially formulated for a two-dimensional encounter before being extended to a three-dimensional ...

Gap Affordance Judgments in Mixed Reality: Testing the Role of Display Weight and Field of View
Measures of perceived affordances—judgments of action capabilities—are an objective way to assess whether users perceive mediated environments similarly to the real world.

Risley-prism-based image sensors can expand the imaging field of view through beam control. The larger the top angle of the prism, the higher the magnification of the field of view, but at the same time, it aggravates the problem of imaging aberrations ...

The Maximum Cover with Rotating Field of View
Abstract In this paper, we address the maximum cover problem of a rotating field of view (FOV) with a convex polygon $$\mathcal {P}$$ P with n vertices. The problem is defined as determining the optimal rotation angle

Mapping Burned Areas in Tropical Forests Using a Novel Machine Learning Framework
This paper presents an application of a novel machine-learning framework on MODIS (moderate-resolution imaging spectroradiometer) data to map burned areas over tropical forests of South America and South-east Asia.
