Digital Divide
The digital divide refers to the gap between individuals, communities, or countries that have access to and effectively use digital technologies, such as the internet and computers, and those who do not. It is a significant socio-economic and technological disparity that can have far-reaching consequences on education, economic opportunities, social inclusion, and overall development. Here…

Algorithmic Bias and Fairness
Algorithmic bias and fairness are critical ethical considerations in the development and deployment of artificial intelligence (AI) systems and algorithms. Algorithmic bias refers to the presence of unfair or discriminatory outcomes that result from biased data or the design of the algorithm itself. Here’s a closer look at these issues: Types of Bias: Data Bias:…

Microscopic description of fission in nobelium isotopes with the Gogny-D1M energy density functional
R. Rodriguez-Guzman, L.M. Robledo Constrained mean-field calculations, based on the Gogny-D1M energy density functional, have been carried out to describe fission in the isotopes 250−260No. The even-even isotopes have been considered within the standard Hartree-Fock-Bogoliobov (HFB) framework while for the odd-mass ones the Equal Filling Approximation (HFB-EFA) has been employed. Ground state quantum numbers and deformations,…

Actinide chemistry using singlet-paired coupled cluster and its combinations with density functionals
Alejandro J. Garza, Ana G. Sousa Alencar, Gustavo E. Scuseria Singlet-paired coupled cluster doubles (CCD0) is a simplification of CCD that relinquishes a fraction of dynamic correlation in order to be able to describe static correlation. Combinations of CCD0 with density functionals that recover specifically the dynamic correlation missing in the former have also been…

γ-vibrational states in superheavy nuclei
Yang Sun, Gui-Lu Long, Falih Al-Khudair, and Javid A. Sheikh Recent experimental advances have made it possible to study excited structure in superheavy nuclei. The observed states have often been interpreted as quasiparticle excitations. We show that in superheavy nuclei collective vibrations systematically appear as low-energy excitation modes. By using the microscopic Triaxial Projected Shell…

Rotational properties of nuclei around 254No investigated using a spectroscopic-quality Skyrme energy density functional
Yue Shi, J. Dobaczewski, P.T. Greenlees Nuclei in the Z≈100 mass region represent the heaviest systems where detailed spectroscopic information is experimentally available. Although microscopic-macroscopic and self-consistent models have achieved great success in describing the data in this mass region, a fully satisfying precise theoretical description is still missing. By using fine-tuned parametrizations of the energy density…
