Database slicing on relational databases
Many software systems today use databases to permanently store their data. Testing, bug finding and migration are complex problems in the case of databases that contain many records. Here, our method can speed up these processes if we can select a smaller piece of the database (called a slice) that contains all of the records belonging to the slicing criterion. The slicing criterion might be, for example, a record which gives rise to a bug in the program. Database slicing seeks to select all the records belonging to a specific slicing criterion. Here, we introduce the concept of database slicing and describe the algorithms and data structures necessary for slicing a given database. We define the Table-based and the Record-based slicing algorithms and we empirically evaluate these methods in two scenarios by applying the slicing to the database of a real-life application and to random generated database content
Pre-Born-Oppenheimer Dirac-Coulomb-Breit computations for two-body systems
The sixteen-component, no-pair Dirac--Coulomb--Breit equation, derived from
the Bethe--Salpeter equation, is solved in a variational procedure using
Gaussian-type basis functions for the example of positronium, muonium, hydrogen
atom, and muonic hydrogen. The fine-structure-constant dependence of
the variational energies, through fitting a function of and
terms, shows excellent agreement with the relevant
energy expressions of the (perturbative) non-relativistic QED framework, and
thereby, establishes a solid reference for the development of a computational
relativistic QED approach
Benchmark potential energy curve for collinear H
A benchmark-quality potential energy curve is reported for the H system
in collinear nuclear configurations. The electronic Schr\"odinger equation is
solved using explicitly correlated Gaussian (ECG) basis functions using an
optimized fragment initialization technique that significantly reduces the
computational cost. As a result, the computed energies improve upon recent
orbital-based and ECG computations. Starting from a well-converged basis set, a
potential energy curve with an estimated sub-parts-per-billion precision is
generated for a series of nuclear configurations using an efficient ECG
rescaling approach
Variational versus perturbative relativistic energies for small and light atomic and molecular systems
Variational and perturbative relativistic energies are computed and compared
for two-electron atoms and molecules with low nuclear charge numbers. In
general, good agreement of the two approaches is observed. Remaining deviations
can be attributed to higher-order relativistic, also called non-radiative
quantum electrodynamics (QED), corrections of the perturbative approach that
are automatically included in the variational solution of the no-pair
DiracCoulombBreit (DCB) equation to all orders of the
fine-structure constant. The analysis of the polynomial dependence of
the DCB energy makes it possible to determine the leading-order relativistic
correction to the non-relativistic energy to high precision without
regularization. Contributions from the BreitPauli Hamiltonian, for which
expectation values converge slowly due the singular terms, are implicitly
included in the variational procedure. The dependence of the no-pair
DCB energy shows that the higher-order () non-radiative
QED correction is 5 % of the leading-order ()
non-radiative QED correction for (He), but it is 40 % already for
(Be), which indicates that resummation provided by the variational
procedure is important already for intermediate nuclear charge numbers
