A rare case of campomelic dysplasia: a case report

We report an uncommon case of campomelic dysplasia in a24-year-old patient nuliparva, pregnantin 38g.w. with breech presentation, admitted at the Specialized Obstetrics and Gynecology Hospital. The ultrasound Examination visualized Intrauterine Growth Retardation (IUGR) as well as severe angulation and rhizomelic Short ening of the femur and tibia. Those ultrasonography features suggested the presence of campomelic dysplasia. After aplanned Cesarian section, a female baby was delivered, weighing 2250 gr. Thepostnata lX ray was managed and the diagnosis was confirmed without other abnormallites. The genetic testing established normal karyo types of the parents and we suggested the new SOX9 mutation of the baby. No individual Feature is pathognomonic of this condition, however the most typical characteristic sign of campomelic Dysplasiais the marked anterior bowing of the long bones, particularly of the femur and tibia.Scripta Scientifica Medica 2011;43(2):73-7

Unusual case of an enormous dermoid cyst in a 16-year-old gir

We present the case of a 16-year old girl with alarged ermoid cyst from right ovary. Ultrasound examination and MRI were performed, which visualized a huge multilocular ovarian tumour formation, situated in pelvic and whole abdominal cavity. We performed anex ploratory laparotomy, oophorocystectomy and, in our case, the organ preserving operation was completely sufficient. The histological examinations reported mature cystic teratomas (Dermoids) without morphological data for malignant transformation.Scripta Scientifica Medica 2011;43(2):77-7

Semileptonic form factors - a model-independent approach

We demonstrate that the B->D(*) l nu form factors can be accurately predicted given the slope parameter rho^2 of the Isgur-Wise function. Only weak assumptions, consistent with lattice results, on the wavefunction for the light degrees of freedom are required to establish this result. We observe that the QCD and 1/m_Q corrections can be systematically represented by an effective Isgur-Wise function of shifted slope. This greatly simplifies the analysis of semileptonic B decay. We also investigate what the available semileptonic data can tell us about lattice QCD and Heavy Quark Effective Theory. A rigorous identity relating the form factor slope difference rho_D^2-rho_A1^2 to a combination of form factor intercepts is found. The identity provides a means of checking theoretically evaluated intercepts with experiment.Comment: 18 pages, Revtex, 4 postscript figures, uses epsfig.st

Flux Tubes in Effective Field Theory

Quark-antiquark bound states are examined in the long-range strong-coupling limit with the minimal area law of lattice gauge theory assumed as input. Matrix element relations are established which in the effective theory obtain dynamical equations equivalent to a formulation of the flux-tube model.Comment: Latex, 11 page

Direct experimental test of scalar confinement

The concept of Lorentz scalar quark confinement has a long history and is still widely used despite its well-known theoretical faults. We point out here that the predictions of scalar confinement also conflict directly with experiment. We investigate the dependence of heavy-light meson mass differences on the mass of the light quark. In particular, we examine the strange and non-strange D mesons. We find that the predictions of scalar confinement are in considerable conflict with measured values.Comment: REVTeX4, 7 pages, 4 EPS figure

The EPICS Software Framework Moves from Controls to Physics

The Experimental Physics and Industrial Control System (EPICS), is an open-source software framework for high-performance distributed control, and is at the heart of many of the world’s large accelerators and telescopes. Recently, EPICS has undergone a major revision, with the aim of better computing supporting for the next generation of machines and analytical tools. Many new data types, such as matrices, tables, images, and statistical descriptions, plus users’ own data types, now supplement the simple scalar and waveform types of the former EPICS. New computational architectures for scientific computing have been added for high-performance data processing services and pipelining. Python and Java bindings have enabled powerful new user interfaces. The result has been that controls are now being integrated with modelling and simulation, machine learning, enterprise databases, and experiment DAQs. We introduce this new EPICS (version 7) from the perspective of accelerator physics and review early adoption cases in accelerators around the world

The anomalous threshold, confinement, and an essential singularity in the heavy-light form factor

The analytic behavior of the heavy-light meson form factor is investigated using several relativistic examples including unconfined, weakly confined, and strongly confined mesons. It is observed that confinement erases the anomalous threshold singularity and also induces an essential singularity at the normal annihilation threshold. In the weak confinement limit, the "would be" anomalous threshold contribution is identical to that of the real singularity on its space-like side.Comment: Latex 2.09 with epsf.sty. 24 pages of text and 8 postscript figures.
