Simulation Research on Star Map in Celestial Attitude Determination [PDF]

open access: yesJisuanji gongcheng, 2016
A new method of star map simulation is proposed to test and evaluate the performance of star sensors.To start with,a star position calculation model based on the spacecraft is established,and stars are drawed in the celestial sphere according to the star

RJA-Star Algorithm for UAV Path Planning Based on Improved R5DOS Model

open access: yesApplied Sciences, 2023
To improve the obstacle avoidance ability of agricultural unmanned aerial vehicles (UAV) in farmland settings, a three-dimensional space path planning model based on the R5DOS model is proposed in this paper. The direction layer of the R5DOS intersection

A progeroid syndrome caused by a deep intronic variant in TAPT1 is revealed by RNA/SI‐NET sequencing

open access: yesEMBO Molecular Medicine, 2023
Exome sequencing has introduced a paradigm shift for the identification of germline variations responsible for Mendelian diseases. However, non‐coding regions, which make up 98% of the genome, cannot be captured.

Hadron Star Models [PDF]

open access: yesSymposium - International Astronomical Union, 1974
The properties of fully relativistic rotating hadron star models are discussed using models based on recently developed equations of state. All of these stable neutron star models are bound with binding energies as high as ∼ 25%. During hadron star formation, much of this energy will be released.

STAR-MATRIX MODELS [PDF]

open access: yesModern Physics Letters A, 1995
The star-matrix models are difficult to solve due to the multiple powers of the Vandermonde determinants in the partition function. We apply to these models a modified Q-matrix aprpoach and we get results consistent with those obtained by other methods.

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly

open access: yesThe Astrophysical Journal, 2023
Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

A High-Accuracy Star Centroid Extraction Method Based on Kalman Filter for Multi-Exposure Imaging Star Sensors

open access: yesSensors, 2023
A multi-exposure imaging approach proposed in earlier studies is used to increase star sensors’ attitude update rate by N times. Unfortunately, serious noises are also introduced in the star image due to multiple exposures.

Star-forming Filament Models [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract New models of star-forming filamentary clouds are presented in order to quantify their properties and to predict their evolution. These 2D axisymmetric models describe filaments that have no core, one low-mass core, and one cluster-forming core.

The NLRP3 Inflammasome May Contribute to Pathologic Neovascularization in the Advanced Stages of Diabetic Retinopathy

open access: yesScientific Reports, 2018
Diabetic retinopathy (DR) is a retinal microvascular disease characterized by inflammatory and angiogenic pathways. In this study, we evaluated NLRP3 inflammasome in a double transgenic mouse model, Akimba (Ins2 Akita xVEGF +/−), which demonstrates ...
