Study provides deeper insight into artificial intelligence object detection and segmentation

In many engineering fields of data processing , such as deep space object detection and tracking .In this study , the detection is not carried out completely after optimization on the reconstructed data , but rather recovers edge informa...In many engineering fields of data processing, such as deep space object detection and tracking, people need to detect features, such as edge and shape information of the asteroid targets and celestial surfaces, from incomplete measureme...

The measurement of the magnetic field in the eclipse medium of a spider pulsar PSR J2051-0827

Spider pulsars are a subclass of millisecond pulsar binary systems with low mass companions in short-period orbits. In spider pulsars, the pulsar wind and electromagnetic emission ablate and may destroy the companion. The study of spider...Spider pulsars are a subclass of millisecond pulsar binary systems with low mass companions in short-period orbits.

Researchers found correlations between multiband light curves of PKS 1510-089

Currently , very high-energy γ - rays have been detected in 67 BL Lac objects .These include observations in the gamma-ray band conducted by the space-based Fermi Large Area Telescope , optical and near-infrared bands observation by the...Currently, very high-energy γ-rays have been detected in 67 BL Lac objects; very high-energy γ-rays have only been detected in only 9 flat-spectrum radio quasars (FSRQs). This is because there is less absorbing medium at the TeV energ...

Researchers Discovered Annular Distribution of SiC2 towards carbon-rich AGB stars by ALMA Observations

The circumstellar envelopes ( CSE ) of asymptotic giant branch ( AGB ) stars contain a large number of molecules ( 105 have been detected ) , which account for about one-third of all molecules discovered in interstellar space ( over.Chin...The circumstellar envelopes (CSE) of asymptotic giant branch (AGB) stars contain a large number of molecules (105 have been detected), which account for about one-third of all molecules discovered in interstellar space (over 300).

Researchers discover the gravitational collapse and accretion flows in hub filament system G323.46-0.08

Hub-filament systems are ubiquitous in molecular clouds. Most dense clumps and cores are formed in filaments and play a key role in the star formation process. Therefore, investigating the hub-filament system is one of the best ways to u...Hub-filament systems are ubiquitous in molecular clouds.
