Real Time RT-PCR02:57

Real Time RT-PCR

65.3K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Dense Connective Tissue

12.3K
Dense connective tissue contains more collagen fibers than loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue— regular and irregular.
Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...

pH Scale

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Scaling01:26

Scaling

597
In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Real Number System

1.2K
The real number system includes all numbers used for counting, measuring, and comparing quantities. Natural numbers are the basic counting numbers: 1, 2, 3, and so on. Integers expand this set by including zero and negative whole numbers: ..., –3, –2, –1, 0, 1, 2, .... Rational numbers are those that can be expressed as the ratio of two integers m/n, where n≠0. This includes fractions like 1/2​, integers such as 46, and decimals that terminate, such as 0.17, or...

Microtubule Associated Proteins (MAPs)01:42

Microtubule Associated Proteins (MAPs)

6.0K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

Area of Science:

  • Computer Vision
  • Robotics
  • 3D Reconstruction

Background:

  • Real-time dense mapping systems using RGB-D cameras are crucial for applications like robotics and augmented reality.
  • Existing systems using truncated signed distance function (TSDF) or surfel models face limitations in handling large scenes and loop closures due to tracking drift and map size.
  • The efficiency of surfel-based systems degrades as the number of map points increases, hindering real-time performance.

Purpose of the Study:

  • To develop a novel dense mapping system that overcomes the limitations of existing methods in terms of scale and efficiency.
  • To improve the accuracy and robustness of dense surface reconstruction, especially around loop closures and in the presence of large surface deformations.
  • To maintain high frame rates even when reconstructing very large scenes.

Main Methods:

  • A dual-map approach is proposed, integrating RGB-D images into a local surfel map while transferring older, distant surfels to a global map.
  • Loop closure detection and pose graph optimization are employed to mitigate system tracking drift.
  • An embedded deformation graph corrects surfel positions and normals based on updated poses, and a new constraint construction method addresses large-scale surface deformations.

Main Results:

  • The proposed system demonstrates the ability to reconstruct very large scenes while maintaining a high frame rate.
  • The system effectively handles and stabilizes large-scale surface deformations.
  • Experimental results indicate superior performance compared to state-of-the-art dense mapping systems.

Conclusions:

  • The novel two-map dense mapping system offers significant improvements in scalability, efficiency, and accuracy over existing methods.
  • The system's ability to handle large deformations and maintain real-time performance makes it suitable for complex real-world applications.
  • This work advances the field of real-time dense mapping, providing a more robust solution for large-scale 3D reconstruction.
