Protein Folding

Protein Folding

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Molecular Chaperones and Protein Folding

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

Moment of Inertia about an Arbitrary Axis

Moment of Inertia about an Arbitrary Axis

The moment of inertia is typically associated with principal axes, but it can also be computed for any random axis. When an arbitrary axis is under consideration, the moment of inertia is determined by integrating the mass distribution of the object along that specific axis. It is crucial in applications like the design of machinery, where components rotate about various axes, and balance and stability are essential.
In this scenario, the perpendicular distance between the chosen arbitrary axis...

Angular Momentum about an Arbitrary Axis

Angular Momentum about an Arbitrary Axis

Imagine a rigid body with a mass denoted as 'm', which has its center of mass at point G and is rotating around an inertial reference frame. The angular momentum at an arbitrary point P can be calculated by taking the cross product of the position vector and linear momentum vector for each individual mass element.
The velocity of a mass element comprises its translational velocity and the relative velocity instigated by the body's rotation. Substituting the velocity equation into...

Background:

Traditional invisibility cloaks are limited to enclosing objects directly.
A need exists for cloaking devices that can operate remotely, independent of direct object contact.

Purpose of the Study:

To introduce a novel method for designing a remote cloaking device.
To demonstrate the capability of making arbitrary objects invisible at a distance.
To extend the concept to remote illusion optics.

Main Methods:

Utilizing multi-folded transformation optics to create a remote cloaking effect.
Generating a hidden region that prevents field penetration.
Ensuring no disturbance to the far-field scattering electromagnetic field.

Main Results:

Successfully designed a remote cloaking device capable of rendering distant objects invisible.
Demonstrated that objects within the hidden region remain undetected and can move freely.
Extended the methodology to achieve remote illusion optics, transforming objects without prior knowledge of their details.

Conclusions:

The proposed multi-folded transformation optics offers a new paradigm for remote cloaking and illusion.
This technology has significant potential for applications requiring remote invisibility or object transformation.
The method's independence from object-specific details broadens its applicability in diverse scientific and technological contexts.
