Face recognition is one of the most ubiquitous examples of pattern recognition in machine learning, with numerous applications in security, access control, and law enforcement, among many others. Pattern recognition with classical algorithms requires significant computational resources, especially when dealing with high-resolution images in an extensive database. Quantum algorithms have been shown to improve the efficiency and speed of many computational tasks, and as such, they could also potentially improve the complexity of the face recognition process.

- - Spontaneous parametric downconversion is used to create entangled photons for experiments in quantum photonics, with correlations observed in various properties, including spatial modes.
- - Past research mostly focused on polar coordinates and a few radial states, but this study examines full-mode correlations using a Laguerre-Gauss basis in photon pairs from a type-I crystal.
- - The research also investigates how different spatial modes of a structured pump beam impact bi-photon spatial correlation and utilizes arbitrary spatial mode projections for comprehensive quantum tomography in a 16-dimensional subspace.
Protonated azobenzene (AB), H(CHNCH), has been studied using threshold collision-induced dissociation in a guided ion beam tandem mass spectrometer. Product channels observed are CHN + CH and CH + N + CH. The experimental kinetic energy-dependent cross sections were analyzed using a statistical model that accounts for internal and kinetic energy distributions of the reactants, multiple collisions, and kinetic shifts.

The trans 2,2',6,6'-tetrafluoroazobenzene anion was prepared by atmospheric pressure chemical ionization for the collision induced dissociation (CID) experiment and through thermal electron attachment in the photodetachment-photoelectron spectroscopy experiments. The adiabatic electron affinity of trans 2,2',6,6'-tetrafluoroazobenzene was measured to be 1.

Objectives: This study is designed to compare the S. aureus super antigens level in sera of psoriatic patients with normal cases (nevus).
