Accurate Light Field Depth Estimation Using Multi-Orientation Partial Angular Coherence

IEEE Access, 2019
Occlusion is a critical issue that affects the accuracy for light field depth estimation. In the presence of occlusions, the photo-consistency property is broken, making ambiguity near occlusion areas.

Shared HLA class I and II alleles and clonally restricted public and private brain-infiltrating alpha beta T cells in a cohort of Rasmussen encephalitis surgery patients

Frontiers in Immunology, 2016
Rasmussen encephalitis (RE) is a rare pediatric neuroinflammatory disease characterized by intractable seizures and unilateral brain atrophy. T cell infiltrates in affected brain tissue, and the presence of circulating autoantibodies in some RE patients ...

Co-Phase Error Detection for Segmented Mirrors Based on Far-Field Information and Transfer Learning

Photonics
The resolution of a telescope is closely related to its aperture size; however, the aperture of a single primary mirror telescope cannot be indefinitely enlarged due to design and manufacturing constraints.

Interactive effects of temperature and phosphorus nutrition on soybean: leaf photosynthesis, chlorophyll fluorescence, and nutrient efficiency

Photosynthetica, 2019
An experiment was conducted to assess interactive effects of temperature (22, 26, 30, and 34°C daily mean T) and phosphorus (P) fertilization (sufficient, 0.5 mM, and deficient, 0.08 mM P) on soybean physiological traits.

Real-Time Controller Based on FPGA and DSP for Solar Ground Layer Adaptive Optics Prototype System at 1-m NVST

IEEE Photonics Journal, 2017
Solar ground layer adaptive optics (GLAO), containing a large field of view (FOV) wavefront sensor (WFS) and one deformable mirror (DM), can be used to reduce and stabilize the seeing effectively over a wide FOV. As the brain of the GLAO system, the real-

Is adaptation. Truly an adaptation? Is adaptation. Truly an adaptation?

Ilha do Desterro, 2008
The article begins by historicizing film adaptation from the arrival of cinema, pointing out the many theoretical approaches under which the process has been seen: from the concept of “the same story told in a different medium” to a comprehensible definition such as “the process through which works can be transformed, forming an intersection of textual
