AB  - The 12-lead electrocardiogram (ECG) is a first-line diagnostic tool for patients with cardiac symptoms. As observed during the COVID-19 pandemic, the ECG is essential to the initial patient evaluation. The novel KardioPal three-lead-based ECG reconstructive technology provides a potential alternative to a standard ECG, reducing the response time and cost of treatment and improving patient comfort. Our study aimed to evaluate the diagnostic accuracy of a reconstructed 12-lead ECG obtained by the KardioPal technology, comparing it with the standard 12-lead ECG, and to assess the feasibility and time required to obtain a reconstructed ECG in a real-life scenario. A prospective, nonrandomized, single-center, adjudicator-blinded trial was conducted on 102 patients during the COVID-19 pandemic at the Dedinje Cardiovascular Institute in Belgrade. The KardioPal system demonstrated a high feasibility rate (99%), with high specificity (96.3%), sensitivity (95.8%), and diagnostic accuracy (96.1%) for obtaining clinically relevant matching of reconstructed 12-lead compared to the standard 12-lead ECG recording. This novel technology provided a significant reduction in ECG acquisition time and the need for personnel and space for obtaining ECG recordings, thereby reducing the risk of viral transmission and the burden on an already overwhelmed healthcare system such as the one experienced during the COVID-19 pandemic.

AB  - The controlled and patterned reduction of graphene oxide offers a promising method to tune the electronic and optical properties of the material through a wide range. Using ab initio calculations in which the exact exchange energy from Hartree-Fock theory is combined with the exchange-correlation energy obtained from density functional theory (DFT), we studied the electronic, optical, and radiative recombination properties of reduced graphene oxide (rGO). Our model of rGO is based on epoxy functionalised graphene, within which small regions of pristine graphene are formed by reduction. We predict that the gap can be tuned from similar to 6.85 eV to similar to 0.25 eV in this manner and that the polarization selective absorption properties can be controlled by manipulating the symmetry of these graphene quantum dots. The optically active can therefore be tuned to ranges suitable for use either as the active medium or a transparent conducting oxide (TCO) in photovoltaic solar cells (PVSCs).

AB  - Our current understanding of the symmetries of multiband envelope function Hamiltonians for semiconductor quantum dots and their signatures in the energy level structure and wave function shapes is reviewed. We show how sym- metry can be used to block-diagonalize the Hamiltonian matrix and consequently strongly reduce the computational effort. A detailed analysis of symmetries of several different model Hamiltonians reveals that the true symmetry of square- based pyramidal quantum dots is captured if either the interface effects are taken into account or additional higher energy bands are included in the multiband Hamiltonian. This indicates that multiband envelope function methods are fully capable of capturing the true atomistic symmetry of quantum dots in contrast to some widespread beliefs. In addition, we show that translational symmetry can be artificially introduced by the numerical method used, such as the plane wave method. Plane wave method introduces artificial quantum dot replica whose charges interact with charges in the real quantum dot and create an additional strain field in the real dot. This issue can be circumvented by the introduction of proper corrections in the procedure for calculation of Coulomb integrals and strain.

AB  - Vertically or laterally coupled semiconductor quantum dot (QD) arrays emerged recently as promising structures for the next generation of high-efficiency intermediate band solar cell (IBSC), due to their ability to facilitate the formation of mini-bands. The quantum coupling effect, that exists between states in QDs of an array, influences the electronic and optical properties of such structures. We present here a method based on multi-band k ⋅ p Hamiltonian combined with periodic boundary conditions, applied to predict the electronic and optical properties of InAs/GaAs QDs based vertical and lateral QD arrays. Formation of the intermediate band (IB) in all cases was achieved via delocalisation of the electron ground state (e0). By changing the geometry of the QD arrangement in arrays we have identified conditions for the IB to be separated by a pure zero density of states from the rest of states in the conduction band (CB). Due to symmetry of the QD array lattice and QD states itself, which are C 2v for the zinc blende QDs, the electronic and absorption structure needs to be obtained via sampling throughout the reciprocal space in the first Brillouin zone of QD arrays.

AB  - We present a theoretical model for design and analysis of semiconductor quantum dot (QD) array-based intermediate band solar cell (IBSC). The plane wave method with periodic boundary conditions is used in expansion of the k⋅p Hamiltonian for calculation of the electronic and optical structure of InAs/GaAs QD array. Taking into account realistic QD shape, QD periodicity in the array, as well as effects like band mixing between states in the conduction and valence band, strain and piezoelectric field, the model reveals the origin of the intermediate band formation inside forbidden energy gap of the barrier material. Having established the interrelation between QD periodicity and the electronic structure across the QD array Brillouin zone, conditions are identified for the appearance of pure zero density of states regions that separate intermediate band from the rest of the conduction band. For one realistic QD array, we have estimated all important absorption spectra in IBSC, and most important, radiative and nonradiative scattering times. Under radiative limit approximation, we have estimated efficiency of such IBSC to be 39%.

AB  - The Band Anti-Crossing (BAC) model describes the strong band gap bowing at low N composition x in Ga(In)NxAs1-x in terms of an interaction between the conduction band edge (CBE) and a higher lying band of localised nitrogen resonant states. We use an sp3s* tight-binding (TB) Hamiltonian here to investigate the BAC model and its application. We demonstrate that the alloy CBE (the so-called E- level) can be described very accurately by the BAC model, in which we treat the nitrogen levels explicitly using a linear combination of isolated nitrogen resonant states (LCINS). We also use the LCINS results to identify a higher lying resonance (the E1 level) in the full tight-binding calculations, showing that at low N composition E+ forms a sharp resonance in the conduction band Γ-related density of states, which broadens rapidly at higher N composition when the E+ level rises in energy to become degenerate with the larger L-related density of states. We then present an analytical technique through which it is possible to calculate both the electron confined state energies and conduction band dispersion in Ga(In)NAs square quantum well (QW) structures. This analytical model provides a consistent fit of the ground and excited state transition energies measured across a wide range of samples. Turning to the conduction band dispersion, we show that the two-level BAC model must be modified to give a quantitative understanding of measured electron effective mass values. We demonstrate that the unexpectedly large mass values observed in some GaNAs samples are due to hybridisation between the CBE and nitrogen states close to the band edge. Finally we show that there is a fundamental connection between the strong composition dependence of the CBE energy and the n-type carrier scattering cross-section in Ga(In)NxAs1-x alloys, imposing general limits on the carrier mobility, comparable to the highest measured mobility in such alloys.

AB  - A procedure for the design of quantum well structures optimized as regards intersubband double-resonant second-harmonic generation is proposed. It relies on the inverse spectral theory, allowing one to start from an arbitrary potential and shift its levels to the positions required for a particular application, in this case such that they become equispaced. The free parameters that appear, and determine the shape of the modified potential, are then varied in order to find the optimal potential shape that maximizes the nonlinearity, while level energies are automatically fixed throughout this variation. Furthermore, the procedure is adapted to handle cases of variable effective mass, unlike the conventional inverse spectral theory. The use of this procedure is demonstrated by the designing of a graded AlGaAs ternary alloy quantum well optimized for second-order nonlinearity at 10.6 mu m. Starting with a truncated parabolic potential, the final optimized quantum well potential is obtained, with nonlinearity exceeding values previously obtained in the literature.

AB  - A systematic procedure is proposed for optimized design of semiconductor quantum well structures that provide maximal values of the resonant optical rectification coefficient. It relies on employing supersymmetric quantum mechanics to vary the starting potential in the isospectral manner, via the variation of a single scalar parameter, in search of the largest available value of the appropriate product of matrix elements (difference of permanent moments times the transition dipole moment squared, in this instance). An example design of the structure matched for the optical rectification of 10.6 mu m (CO2 laser) radiation is presented. It starts from the truncated parabolic potential and delivers a rectification coefficient in excess of the best value reported in the literature. The possibility of realization of optimized structures is also discussed. (C) 1997 Elsevier Science B.V.
