Serverless–edge computing with mobile document agents

Exchange of documents as email attachments in collaborative work lacks support for keeping track of
threads of performed activities, what often leads to email overload and strain. Proactive document email
attachments linking the passive content and active services could build reproducibility in collaborative
processes, even if workers may tend to exchange emails indiscriminately. The key role in achieving that
play workflow patterns identified in the real-world organizations. A small and well defined set of doc-
ument coordination patterns based on them is proposed in the paper. It provides building blocks for the
migration path embedded in the document code, which interpreted by the specially designed smart email
client (SEC) can support document steering. Owing to that an email system can provide a platform for
document centric processing and can introduce self-organization in the dynamically set virtual organiza-
tion using it. Proactive documents exchanged as standard MIME attachments enable any type of working
content with reduced workload and improved work performance, without any substantial investment in
the job resources already available in the workplace. Moreover, they enable smooth incorporation of the
email based collaboration in solutions that push further the boundaries of building overall intelligence and
enhanced cognition across the cloud-edge continuum.

Hydrogen and exotic atoms in rotationally-invariant space with noncommutativity of coordinates and noncommutativity of momenta

The effect of the noncommutativity of coordinates and noncommutativity of momenta on the spectrum of the hydrogen atom is studied. Corrections to the energy levels of the atom up to the second order in the parameter of noncommutativity are found. Based on the obtained results and the experimental data for the 1S-2S transition frequency, the upper bound for the minimal length is obtained. Also, a two-particle system with Coulomb interaction is examined and hydrogen-like exotic atoms are studied in rotationally-invariant noncommutative phase space.

An overview of numerical methods for modeling x-ray propagation through a multi-lens system

This article offers a comprehensive examination of the field of X-ray optics and the methods employed to simulate X-ray propagation through multi-lens systems. The publication presents three distinct approaches to address X-ray optics problems, including the utilization of oriented Gaussian beams, the fast Fourier transform, and the second-order Runge-Kutta method. It also provides an in-depth analysis of the paraxial wave equation used in X-ray optics and how the paraxial approximation can be employed to reduce computational complexity. Finally, the article provides a detailed mathematical description of the concave lens used in X-ray focusing.

Furthermore, the article offers a comparative analysis of each method's advantages, disadvantages, and limitations. It also highlights the differences in computation speed, required data points, and precision of each approach.
