We present systematic and large-scale calculations for the fine-structure energy splitting and transition rate between the 3d9D3/2,5/22 levels of Co-like ions with 28≤Z≤100. Two different fully relativistic approaches are used, based on the multiconfiguration Dirac-Hartree-Fock (MCDHF) theory and the relativistic many-body-perturbation theory (RMBPT). Especially the former gives results of similar accuracy as experiments for a large range of ions. Our calculations are therefore accurate enough to probe Breit and quantum-electro-dynamic effects. To obtain spectroscopic accuracy, we show that it is important to include deep core-valence correlation, down to and including the n=2 shell. We estimate that the uncertainties of our wavelengths are within the uncertainty of experiments, i.e., 0.02%. We also show that the frequently used flexible atomic code has an inaccurate treatment of the self-energy (SE) contribution and of the M1-transition properties for lower-Z ions. After correcting for the SE calculation, the resulting RMBPT transition energies are in good agreement with the MCDHF ones, especially for the high-Z end of the Co-like sequence.

The aim of this work was to apply mathematical-computational modeling to study the interactions of haloperidol (HLP) and biperiden (BPD) with human (HSA) and bovine (BSA) serum albumin in order to verify the competition of these drugs for binding sites in HSA, using intrinsic tryptophan fluorescence quenching data. The association constants estimated for HPD-HSA was 2.17(±0.05) × 107 M−1, BPD-HSA was 2.01(±0.03) × 108 M−1 at 37 °C. Results have shown that drugs do not compete for the same binding sites in albumin.

Multithreshold decoder (MTD) is the simplest type of majority decoder that decodes self-orthogonal codes. Low computational complexity and simple decoding hardware implementation of multithreshold decoders allow using them in high speed communication systems and data storage systems that require decoding information at speeds above 1 Gbit/s. A high-speed software binary multithreshold decoder using a modern computing power of the graphics processing unit (GPU) is considered. Such software implementation of MTD helps to decode several hundred blocks received from the channel completely parallel and independent from each other. It is shown that the speed of software MTD based on GPU GTX 970 can reach 350 Mbit/s.

Classifying structural variability in noisy projections of biological macromolecules is a central problem in Cryo-EM. In this work, we build on a previous method for estimating the covariance matrix of the three-dimensional structure present in the molecules being imaged. Our proposed method allows for incorporation of contrast transfer function and non-uniform distribution of viewing angles, making it more suitable for real-world data. We evaluate its performance on a synthetic dataset and an experimental dataset obtained by imaging a 70S ribosome complex.
