[en] Simple, semiphenomenological theory of the abrupt change of valence in SmS is presented. The phase transition and the softening of the phonon mode can be considered as being due to the partial decoupling of phonons from the electronic system. (author)

[en] The National Ignition Facility (NIF) Integrated Computer Control System (ICCS) is a large (1.5 MSLOC), hierarchical, distributed system that controls all aspects of the NIF laser [1]. The ICCS team delivers software updates to the NIF facility throughout the year to support shot operations and commissioning activities. In 2006, there were 48 releases of ICCS: 29 full releases, 19 patches. To ensure the quality of each delivery, thousands of manual and automated tests are performed using the ICCS Test Controller test infrastructure. The TestController system provides test inventory management, test planning, automated test execution and manual test logging, release testing summaries and test results search, all through a web browser interface. Automated tests include command line based frameworks server tests and Graphical User Interface (GUI) based Java tests. Manual tests are presented as a checklist-style web form to be completed by the tester. The results of all tests, automated and manual, are kept in a common repository that provides data to dynamic status reports. As part of the 3-stage ICCS release testing strategy, the TestController system helps plan, evaluate and track the readiness of each release to the NIF facility

[en] The efficacity of irradiation therapy, as a unique method, was evaluated in 50 women with diagnosed uterine corpus cancer in 1/1 stage of clinical development. These patients refused other forms of therapy (surgery). The results were compared with those observed in 232 women treated by complex technique (surgery and irradiation). The percent of 5 years survival rate in the subjects treated by irradiation only made 54%, while in the complex therapy group it made 81.1%. The difference was found significant. The complications resulting from the irradiation therapy were present in 13 women (26%), while in the complex therapy group these were met in 25 women (10.8%) which difference was also significant. These facts strongly advocate the superiority of complex treatment in recent cases of uterine corpus cancer. (author)

[en] The authors discuss the impact of the strong electron phonon interactions on the physical properties of correlated electrons in the two-dimensional Hubbard model. An easy access to the physical properties of the superconducting state is obtained by solving the Eliashberg equations with explicit momentum-dependent kernels. In order to facilitate the numerical procedure to solve these equations, correlations are treated within the Gutzwiller approximation (i.e., mean-field-slave boson approximation). The authors results strongly support the view that d-wave symmetry is the most important feature of the superconducting state in the copper oxides. A possible extension beyond the mean field approximation is also presented

[en] In 58 women with diagnosed stage 1 uterine cervix cancer radium (27 women) or cesium (31 women) were applied into the vagina or in the uterine cavity, then after about 7 weeks they were submitted to surgical treatment - radical hysterectomy with adnexectomy and excision of the obturatory and iliac lymphnodes (Wertheim Meigs operation). In 16 of these women, considering the marked dimensions of the neoplasm teletherapy in a decreased dose preceded the brachytherapy. Total destruction of the neoplasmatic outgrowth as a result of preoperative radiotherapy was met in 44 women (76%). In 8 women the excised tissues revealed neoplasmatic cells persisting in the uterine cervix and in 6 - in the lymphnodes. These women underwent subsequent post-operative teletherapy. The complications of the adapted technique were analysed and found to fall close within limits of those, accepted in cases of classic primary surgical treatment. No exits and no fistulas were met in the material. The value of brachytherapy applied before surgery is evident as it permitted to evade the post-operative teletherapy in 55% of women and to reduce the external irradiation dose in further 21% of women.

[en] We discuss normal-state properties and the phase diagram of high-T_c copper oxide superconductors on the basis of a five-states model (one d state and two bonding and two nonbonding p states per unit cell) for interacting electrons in a single CuO₂ layer. In particular, quasiparticle bands and densities of states have been derived by applying a generalized Hubbard-I scheme to the five-states model and to the reduced three-states model. We find that in both cases and for realistic values of model parameters the insulating gap opens between an antibonding band of almost pure p character and the antibonding band of mainly d character. The insulating state is thus of the charge-transfer type and introducing holes into the p-like antibonding band metallizes the system. This would mean that in the presence of an attractive interaction at least a part of the Cooper pairs are formed out of only weakly correlated p-type quasiparticles. Insight of the normal-state behavior can be gained from a discussion of the spectral distribution of strongly correlated and more localized d electrons among mobile p electrons or holes. The work is supplemented by a brief discussion of the residual interactions among quasiparticles and by a comparison of our model with more strong-coupling models like the t-J model. Finally, we present formal solutions for the Green's functions by using a more refined decoupling scheme. The influence of the resulting lifetime effects and Kondo-type features on the quasiparticle spectra is briefly discussed
