COMMON MECHANISMS OF SPECIFIC HUMORAL IMMUNE RESPONSE’ SHAPING AND SUSTAINING BY THE EXAMPLE OF IMMUNE RESPONSE TO MEASLES AND RUBELLA VIRUSES

Инфекция и иммунитет, 2014
. T follicular helper cells (Tfh) are a CD4+ Th cell subset promoted the cognate control of antigen-specific B cell immunity. Upon first contact with antigen-primed B cells, Tfh can support either extrafollicularly differentiation into short-lived plasma

Improvement of point cloud feature extraction and alignment algorithms and lidar slam in coal mine underground

Meitan kexue jishu
LiDAR SLAM faces challenges in the narrow and confined unstructured environment of underground coal mines, where inaccurate point cloud pose estimation due to few or complex features can result in distortion or even map construction failure.

SNI-SLAM: Semantic Neural Implicit SLAM

2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
We propose SNI-SLAM, a semantic SLAM system utilizing neural implicit representation, that simultaneously performs accurate semantic mapping, high-quality surface reconstruction, and robust camera tracking. In this system, we introduce hierarchical semantic representation to allow multi-level semantic comprehension for top-down structured semantic ...

Universal Entanglement and an Information‐Complete Quantum Theory

Advanced Physics Research, EarlyView.
This Perspective summarize an informationcomplete quantum theory which describes a fully quantum world without any classical systems and concepts. Here spacetime/gravity, having to be a physical quantum system, universally entangles matter (matter fermions and their gauge fields) as an indivisible trinity, and encodes information‐complete physical ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

ANK1 and EPB41 Variants and The Risk of Steroid‐Induced Osteonecrosis

Arthritis &Rheumatology, Accepted Article.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Direct-ORB-SLAM: Direct Monocular ORB-SLAM

Journal of Physics: Conference Series, 2019
Abstract Simultaneous Localization and Mapping (SLAM) plays an important role in the computer vision and robotics field. The well-known ORB-SLAM extracts ORB features and uses feature matching to estimate the camera pose and construct a sparse map.

Decreased BOLD Signal Variability in Middle‐Aged and Older Adults on the Autism Spectrum

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder. Preliminary evidence suggests an increased risk for early‐onset cognitive and neurological decline in ASD. While brain development in children, adolescents, and young adults with ASD diverges from neurotypical (NT) peers, it remains unclear in older adults with ASD ...

‘The best year’/‘I struggled with everything’: Widening participation experiences of pandemic online learning

British Educational Research Journal, EarlyView.
Abstract Improving retention and graduate outcomes for students from a widening participation (WP) background is key to achieving more equitable outcomes. However, evidence suggests WP students experienced different challenges than their peers during the COVID‐19 pandemic.
