It is well-known that Pythagoras’ ancient Greek equation for right triangles: a2+ b2= c2 , is older than ancient Greece. We also know that in Khufu’s pyramid the height equals the radius of a circle ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation for modern geometry and physics.

Abstract: We proposed a compact torsion sensor with high sensitivity using angle-offset long period grating (AO-LPG) inscribed in multicore fiber (MCF). AO-LPGs can be conveniently fabricated on the ...

Abstract: The conventional single-angle tilted fiber Bragg grating (TFBG) can only excite a certain range of cladding modes, limiting it for refractive index (RI) measurement in a wide range. In this ...
