Fingerprint Enhancement Algorithm Based on Surface Transformation Under Fourier Frequency Domain [PDF]
The previous works enhance fingerprint images in Fourier domain based on block.But there are some shortcomings in these works,they are not robust enough to non-smooth areas,and the size of the window is not easy to determine.A curved- regions-based ...

Entangled Light in Moving Frames
We calculate the entanglement between a pair of polarization-entangled photon beams as a function of the reference frame, in a fully relativistic framework.

ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Photon polarization and Wigner's little group
To discuss one-photon polarization states we find an explicit form of the Wigner's little group element in the massless case for arbitrary Lorentz transformation. As is well known, when analyzing the transformation properties of the physical states, only

ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Covariant Response Theory and the Boost Transform of the Dielectric Tensor
After a short critique of the Minkowski formulae for the electromagnetic constitutive laws in moving media, we argue that in actual fact the problem of Lorentz-covariant electromagnetic response theory is automatically solved within the framework of ...
