Spin-dependent localized Hartree-Fock density-functional approach for the accurate treatment of inner-shell excitation of close-shell atoms
We present a spin-dependent localized Hartree-Fock (SLHF) density-functional
approach for the treatment of the inner-shell excited-state calculation of
atomic systems. In this approach, the electron spin-orbitals in an electronic
configuration are obtained first by solving Kohn-Sham (KS) equation with SLHF
exchange potential. Then a single-Slater-determinant energy of the electronic
configuration is calculated by using these electron spin-orbitals. Finally, a
multiplet energy of an inner-shell excited state is evaluated from the
single-Slater-determinant energies of the electronic configurations involved in
terms of Slater's diagonal sum rule. This procedure has been used to calculate
the total and excitation energies of inner-shell excited states of close-shell
atomic systems: Be, B^+, Ne, and Mg. The correlation effect is taken into
account by incorporating the correlation potentials and energy functionals of
Perdew and Wang's (PW) or Lee, Yang, and Parr's (LYP) into calculation. The
calculated results with the PW and LYP energy functionals are in overall good
agreement with each other and also with available experimental and other ab
initio theoretical data. In addition, we present some new results for highly
excited inner-shell states.Comment: 8 pages and 9 table
Efficient many-party controlled teleportation of multi-qubit quantum information via entanglement
We present a way to teleport multi-qubit quantum information from a sender to
a distant receiver via the control of many agents in a network. We show that
the original state of each qubit can be restored by the receiver as long as all
the agents collaborate. However, even if one agent does not cooperate, the
receiver can not fully recover the original state of each qubit. The method
operates essentially through entangling quantum information during
teleportation, in such a way that the required auxiliary qubit resources, local
operation, and classical communication are considerably reduced for the present
purpose
An evaluation of subjective experiences, effects and overall satisfaction with clozapine treatment in a UK forensic service
Objectives: Patients prescribed clozapine were surveyed to assess (a) the effects, both positive and adverse, and overall satisfaction with clozapine in comparison to previously prescribed antipsychotics and (b) the relative significance of effects experienced, both positive and adverse, in terms of impact on subjective well-being.
Methods: A total of 56 male patients prescribed clozapine at a forensic psychiatric hospital were surveyed using a 27-item questionnaire. All patients had been prescribed clozapine for a minimum of 3 months. Respondents were asked to rate effects and satisfaction with clozapine treatment in comparison with previously prescribed antipsychotic medication on a five-point scale. Respondents were also asked to rate effects experienced with clozapine treatment in terms of impact on subjective well-being on a five-point scale.
Results: A total of 89% of respondents reported greater satisfaction with clozapine than with previously prescribed antipsychotic medication. A majority of patients reported positive effects in terms of an improvement in their quality of life (68%) and social abilities (52%) with clozapine in comparison with previously prescribed antipsychotics. Nocturnal hypersalivation (84%) and weight gain (57%) were the most common adverse effects. Hedonic responses were assessed for each effect in order to determine the associated subjective experiences. The most positive hedonic responses were for quality of life, mood and alertness. In terms of adverse impact on subjective well-being, nocturnal hypersalivation ranked highest.
Conclusions: Patients in a UK forensic sample are largely satisfied with clozapine treatment. The subjective effects of clozapine treatment should be taken into account by clinicians when assessing response. This may provide an opportunity to highlight the positive changes and prioritize management of the most undesirable adverse effects, which is likely to promote compliance and improve longer term treatment outcomes
