lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Molecular Shapes

Molecular Shapes

Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.

Dimensional Analysis

Dimensional Analysis

Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Background:

Binary defocusing is key for high-speed 3D shape measurement, overcoming limitations in fringe projection and projector nonlinearity.
Existing methods struggle with multi-frequency phase-shifting due to challenges in generating simultaneous high-quality fringe patterns at different periods under consistent defocusing.

Purpose of the Study:

To propose a high-speed 3D shape measurement technique for dynamic scenes that overcomes the limitations of existing binary defocusing methods.
To enable accurate and robust phase calculation and unwrapping for dynamic 3D measurements.

Main Methods:

A novel technique employing cyclic complementary Gray-code (CCGC) patterns for high-speed 3D shape measurement.
Utilizing phase-shifting sinusoidal fringes with a single frequency to maintain optimal defocusing for binary dithering.
Employing complementary Gray-code (CGC) patterns for robust phase unwrapping and cyclic coding for extended unambiguous measurement range.

Main Results:

Achieved high-quality 3D results for complex dynamic scenes at a frame rate of 357 fps.
Demonstrated improved measurement accuracy and an extended unambiguous phase measurement range compared to traditional Gray-coding.
Successfully captured dynamic events like falling objects, collapsing blocks, and Newton's cradle impacts in 3D.

Conclusions:

The proposed CCGC pattern technique is feasible and valid for high-speed 3D shape measurement of dynamic scenes.
The method effectively addresses the challenges associated with multi-frequency phase-shifting in binary defocusing techniques.
Offers a robust and accurate solution for 3D shape measurement in applications requiring high speed and precision.
