The local and intermediate structure of stoichiometric LaMnO3 has been studied in the pseudocubic and rhombohedral phases at high temperatures (300-1150 K). Neutron powder diffraction data were collected and a combined Rietveld and high real space resolution atomic pair distribution function analysis was carried out. The nature of the Jahn-Teller (JT) transition around 750 K is confirmed to be ...
Gamow-Teller (GT) transitions in atomic nuclei are sensitive to both nuclear shell structure and effective residual interactions. The nuclear GT excitations were studied for the mass number A = 42, 46, 50, and 54 "f-shell" nuclei in ((3)He, t) charge-exchange reactions. In the (42)Ca → (42)Sc reaction, most of the GT strength is concentrated in the lowest excited state at 0.6 MeV, suggesting th...
We study the thermal phase transition of the fourfold degenerate phases (the plaquette and single-stripe states) in the two-dimensional frustrated Ising model on the Shastry-Sutherland lattice using Monte Carlo simulations. The critical Ashkin-Teller-like behavior is identified both in the plaquette phase region and the single-stripe phase region. The four-state Potts critical end points differ...
High pressure x-ray diffraction measurements on perovskite RMnO3 (R = Dy, Ho and Lu) reveal that varying structural changes occur for different R ions. Large lattice changes (orthorhombic strain) occur in DyMnO3 and HoMnO3 while the Jahn-Teller (JT) distortion remains stable. Conversely, in the small R-ion system LuMnO3, Mn-O bond distortions are observed between 4 and 8 GPa with a broad mini...
مهمترین سندرمهای کرانیوفاسیال دیسوستوزیس (craniofacial dysostosis)، عبارتند از سندرمهای crozoun و apert و pfeiffer و carpenter و saether-chotzen که یافته مشترک آنها بسته شدن زودرس درزهای جمجمه می باشد. این اتفاق سبب بروز علائم متعددی در بیماران می گردد که ناهنجاریهای جمجمه و صورت از جمله آن می باشد. شناسایی دقیق و ارزیابی صحیح از عوامل مهم در انجام جراحیهای بازسازی برای این بیماران به شمار می آ...
Crouzon syndrome and Pfeiffer syndrome are both autosomal dominant craniosynostotic disorders that can be caused by mutations in the fibroblast growth factor receptor 2 (FGFR2) gene. To determine the parental origin of these FGFR2 mutations, the amplification refractory mutation system (ARMS) was used. ARMS PCR primers were developed to recognize polymorphisms that could distinguish maternal an...

The following tabulation was assembled over the years (and is still occasionally updated) to facilitate the preparation of experiments. It was mainly intented as a usefull tool and not as a comparitive study of different model descriptions. Such an effort has recently been undertaken by Pfeiffer, Kratz and Möller [1]. Remark: These files are regarded as dynamical documents. They will be updated...
