We use our newly-developed quantum dynamics code that allows us to study the dynamics of multiple coupled states under the influence of an arbitrary time-dependent external field, to investigate the femtosecond laser-driven process of association and the forbidden transition in the NaRb dimer. In this process, the dimer is excited from the ground t...

Proper triage of COVID-19 patients is a key factor in effective case management, especially with limited and insufficient resources. In this paper, we propose a machine-aided diagnostic system to predict how badly a patient with COVID-19 will develop disease. The prognosis of this type is based on the parameters of commonly used complete blood coun...

Renal tumor malignancy classification is one of the crucial tasks in urology, being a primary factor included in the decision of whether to perform kidney removal surgery (nephrectomy) or not. Currently, tumor malig-nancy prediction is determined by the radiological diagnosis based on computed tomography (CT) images. However, it is estimated that u...

The purpose of the current study was to examine the cortical correlates of imagery depending on instructional modality (guided vs. self-produced) using various sports-related scripts. According to the expert-performance approach, we took an idiosyncratic perspective analyzing the mental imagery of an experienced two-time Olympic athlete to verify w...
Article
Referring to a recent experiment, we theoretically study the process of a two-channel decay of the diatomic silver anion (Ag2−), namely, the spontaneous electron ejection giving Ag2 + e⁻ and the dissociation leading to Ag⁻ + Ag. The ground state potential energy curves of the silver molecules of diatomic neutral and negative ions were calculated us...

Referring to a recent experiment, we theoretically study the process of a two-channel decay of the diatomic silver anion (Ag$_2^-$), namely the spontaneous electron ejection giving Ag$_2$ + e$^-$ and the dissociation leading to Ag$^-$ + Ag. The ground state potential energy curves of the silver molecules of diatomic neutral and negative ion were ca...

MIDAS (Medical Image Dataset Annotation Service) is a custom-tailored tool for creating and managing datasets either for deep learning, as well as machine learning or any form of statistical research. The aim of the project is to provide one-fit-all platform for creating medical image datasets that could easily blend in hospital's workflow. In our...

Adiabatic potential energy curves of the 3sSigma+, 3tSigma+, 2sPi and 2tPi states correlating for large internuclear distance with the K(4s) + Li(2p) atomic asymptote were calculated. Very good agreement between the calculated and the experimental curve of the 2sPi state allowed for a reliable description of the dissociation process through a small...
Article
Ab initio quantum chemistry calculations are performed for the mixed alkali triatomic system. Global minima of the ground and first excited doublet states of the trimer are found and Born-Oppenheimer potential energy surfaces of the Li atom interacting with the LiCs molecule were calculated for these states. The lithium atom is placed at various di...
Article
We report on extensive calculations of quasi-relativistic potential energy curves and, for the first time, transition dipole moments including spin-orbit and scalar-relativistic effects of the NaRb molecule. The calculated curves of the 0+, 0-, 1, 2 and 3 molecular states correlate for large internuclear separation with the fourteen lowest atomic e...
Article
Adiabatic potential energy curves of the $^1\Sigma^+$ and $^1\Pi$ states of the LiH molecule have been calculated. They correlate asymptotically to atomic states, like 2s+1s, 2p+1s, 3s+1s, 3p+1s, 3d+1s, 4s+1s, 4p+1s and 4d+1s. Very good agreement is found between our calculated spectroscopic parameters and experimental ones. The dynamics of the rot...

We report the quasirelativistic potential energy curves including spin-orbit and scalar-relativistic effects of the NaRb molecule. The calculated curves of the 0$^+$, 0$^-$, 1 and 2 molecular states correlate for large internuclear separation with the five lowest atomic energies covering the first P doublet states of the rubidium and sodium atoms....

Adiabatic potential energy curves and spectroscopic constants have been calculated for the NaRb molecule. The results of ten states of the symmetry Σ+, six states of the symmetry Π, and two states of the symmetry Δ are obtained by the nonrelativistic quantum chemical method used with pseudopotentials describing the interaction of valence electrons...

The 4(1)I (+) pound state of LiCs molecule is observed experimentally for the first time. The inverted perturbation approach (IPA) method is used to derive the potential energy curve of the state from the measured spectra. The experiment is accompanied by theoretical calculations of adiabatic potentials for excited states in LiCs including 4(1)I (+...

We present four promising schemes for photoassociative formation of KLi molecule in its ground electronic state. Analysis is based on newly calculated adiabatic potentials supported by transition dipole moments and Franck-Condon factors.

In addition to knowledge of interatomic adiabatic potential energy curves of diatomic systems, it is essential to know electronic transition dipole moments. They are needed in understanding processes like photodissociation, photoassociation, cooling, and trapping. Here, we present electronic transition dipole moments calculated for 74 allowed trans...

Semi-empirical adiabatic potential energy curves of highly excited states of the KRb molecule are calculated as a function of the internuclear distance R over a wide range from 3 to 150 a 0. The diatomic molecule is treated as an effective two-electron system by using the large core pseudopotentials and core polarization potentials. All calculation...

We report adiabatic potential energy curves of the Li + 2 molecule. Our curves are tabulated according to internuclear distance from 2 a0 to 100 a0. We compare our theoretical results with the ones calculated by other authors and potential energy curves derived from experiments. For the ground state and 17 excited states we calculate spectroscopic...

We report adiabatic potential energy curves of the lithium dimer. Our curves are tabulated according to internuclear distance from 3.2a 0 to 88a 0 . We compare our theoretical results with the ones calculated by other authors and potential energy curves derived from experiments. In our approach we use the configuration interaction method where only...

Adiabatic potential energy curves for twenty six low-lying electronic states of Li2 dimer have been computed in the large range of internuclear distances (3.2 a0 ≤ R ≤ 80 a0). Four singlet states (41Σ+u, 21Πu, 21Πg and 11Δg) and four triplet states (53Σ+u, 23Πu, 23Πg and 13Δu) and are presented for the first time. In the calculations the complete-a...
