Lightguide type Maxwellian near-eye display with enlarged horizontal field of view by optical reconfiguration of input image

Journal of Information Display, 2022
We present a novel design of the lightguide type optical see-through Maxwellian near-eye display. The proposed display reconfigures vertically long input images to horizontally long output images for wide horizontal viewing-angle.

Learning Camera Parameters With Weighted Edge Attention From Single-View Images

IEEE Access, 2023
This paper presents a novel Deep Learning (DL) model that estimates camera parameters, including camera rotations, field of view, and distortion parameter, from single-view images.

Anisotropic Field-of-Views in Radial Imaging [PDF]

IEEE Transactions on Medical Imaging, 2008
Radial imaging techniques, such as projection-reconstruction (PR), are used in magnetic resonance imaging (MRI) for dynamic imaging, angiography, and short-imaging. They are robust to flow and motion, have diffuse aliasing patterns, and support short readouts and echo times. One drawback is that standard implementations do not support anisotropic field-

FY-3E Satellite Plasma Analyzer

Atmosphere, 2023
The FY-3E satellite plasma analyzer marks China’s first detection of the characteristics, occurrence, and development of the typical plasma environment in the dawn–dusk orbit space. It provides data source support for operational space weather alerts and

Insights into the long-term (2005–2021) spatiotemporal evolution of summer ozone production sensitivity in the Northern Hemisphere derived with the Ozone Monitoring Instrument (OMI) [PDF]

Atmospheric Chemistry and Physics
Tropospheric ozone (O3) formation depends on the relative abundance of precursor species, nitrogen oxides (NOx), and volatile organic compounds (VOCs). Advancements in satellite retrievals of formaldehyde (HCHO) and nitrogen dioxide (NO2) vertical column

Field‐of‐view limitations in parallel imaging [PDF]

Magnetic Resonance in Medicine, 2004
AbstractParallel imaging is one of the most promising developments in recent years for the acceleration of MR acquisitions. One area of practical importance where different parallel imaging methods perform differently is the manner in which they deal with aliasing in the full‐FOV reconstructed image.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data

Earth and Space Science
Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day.

Theoretical Research on Large Field-of-View Polarization Imaging Based on Dynamic Vision Sensors

Photonics
The combination of dynamic vision sensors (DVSs) and polarization can overcome the limitation of DVSs whereby they can only detect dynamic scenes, and it also has the ability to detect artificial targets and camouflaged targets, and is thus expected to ...

The bifixation field as a function of viewing distance [PDF]

Journal of Vision, 2010
Hering reported that the area over which he could bifixate a target was smaller at near convergence distances than far convergence distances and predicted that in extreme horizontal gaze positions, the temporally directed eye lags behind the nasally directed eye. We tested these predictions using a subjective index of eye position.
