- Deviant as well as changing auditory distractors interfere with short-term memory. According to the duplex model of auditory distraction, the deviation effect is caused by a shift of attention while the changing-state effect is due to obligatory order processing. This theory predicts that foreknowledge should reduce the deviation effect, but should have no effect on the changing-state effect. We compared the effect of foreknowledge on the two phenomena directly within the same experiment. In a pilot study, specific foreknowledge was impotent in reducing either the changing-state effect or the deviation effect, but it reduced disruption by sentential speech, suggesting that the effects of foreknowledge on auditory distraction may increase with the complexity of the stimulus material. Given the unexpected nature of this finding, we tested whether the same finding would be obtained in (a) a direct preregistered replication in Germany and (b) an additional replication with translated stimulus materials in Sweden.

- Therapy with [(90)Y-DOTA(0), Tyr(3)]-octreotide (DOTATOC, where DOTA = tetraazacyclododecane tetraacetic acid and TOC = D-Phe-c(Cys-Tyr-D-Trp-Lys-Thr-Cys)-Thr(ol)) is established for the treatment of metastatic neuroendocrine tumors. Nevertheless, many patients experience disease relapse, and further treatment may cause renal failure. Trials with (177)Lu-labeled somatostatin analogs showed less nephrotoxicity. We initiated a prospective study with (177)Lu-DOTATOC in patients with relapsed neuroendocrine tumors after (90)Y-DOTATOC treatment. METHODS: Twenty-seven patients, pretreated with (90)Y-DOTATOC, were included. The mean time between the last treatment with (90)Y-DOTATOC and (177)Lu-DOTATOC was 15.4 +/- 7.8 mo (SD). All patients were injected with 7,400 MBq of (177)Lu-DOTATOC. Restaging was performed after 8-12 wk. Hematotoxicity or renal toxicity of World Health Organization grade 1 or 2 was not an exclusion criterion. RESULTS: Creatinine levels increased significantly, from 66 +/- 14 micromol/L to 100 +/- 44 micromol/L (P < 0.0001), after (90)Y-DOTATOC therapy. The mean hemoglobin level dropped from 131 +/- 14 to 117 +/- 13 g/L (P < 0.0001) after (90)Y-DOTATOC therapy. (177)Lu-DOTATOC therapy was well tolerated. No serious adverse events occurred. The mean absorbed doses were 413 +/- 159 mGy for the whole body, 3.1 +/- 1.5 Gy for the kidneys, and 61 +/- 5 mGy for the red marrow. After restaging, we found a partial remission in 2 patients, a minor response in 5 patients, stable disease in 12 patients, and progressive disease in 8 patients. Mean hemoglobin and creatinine levels did not change significantly. CONCLUSION: (177)Lu-DOTATOC therapy in patients with relapse after (90)Y-DOTATOC treatment is feasible, safe, and efficacious. No serious adverse events occurred.

- Photovoltaics is amongst the most important technologies for renewable energy sources, and plays a key role in the development of a society with a smaller environmental footprint. Key parameters for solar cells are their energy conversion efficiency, their operating lifetime, and the cost of the energy obtained from a photovoltaic system compared to other sources. The optimization of these aspects involves the exploitation of new materials and development of novel solar cell concepts and designs. Both theoretical modeling and characterization of such devices require a comprehensive view including all scales from the atomic to the macroscopic and industrial scale. The different length scales of the electronic and optical degrees of freedoms specifically lead to an intrinsic need for multiscale simulation, which is accentuated in many advanced photovoltaics concepts including nanostructured regions. Therefore, multiscale modeling has found particular interest in the photovoltaics community, as a tool to advance the field beyond its current limits. In this article, we review the field of multiscale techniques applied to photovoltaics, and we discuss opportunities and remaining challenges.
