Turbulent s.i. wake conservation at a long distance is among unsolved problems at present. it is well known that far wakes have a vortical structure and slowly expand with distance. As was obtained by Dubrovin et al., slow expansion of the wake may be related to the distribution of turbulent viscosity in it. in our work we study the effect of helicity in the wake on the behavior of turbulent viscosity. Taking into account the helical nature of the wake, we can clarify the difference between turbulence inside and outside the wake on the one hand and slowing down of its expansion with time on the other hand.

THE ρ（770）

Chinese Physics C 2016年第10期40卷 694-695页

作者： s. eidelman G. Venanzoni Novosibirsk Frascati

The determination of the parameters of the ρ（770） is beset with many difficulties because of its large width. in physical region fits, the line shape does not correspond to a relativis.i. Breit-Wigner function with a P-wave width, but requires some additional shape parameter. This dependence on parameterization was demonstrated long ago [1]. Bose-Einstein correlations are another source of s.i.ts.i. the ρ（770） line shape, particularly in multiparticle final state systems [2].

in our 1988 edition, we replaced the ρ（1600） entry with two new ones, the ρ（1450） and the ρ（1700）, because there was emerging evidence that the 1600-MeV region actually contains two ρ-like resonances. Erkal [1] had pointed out this pos.i.ility with a theoretical analysis on the consistency of 2π and 4π electromagnetic form factors and the ππ scattering length. Donnachie [2],

Developmental dysplasia of the hip(DDH) describes the spectrum of structural abnormalities that involve the growing hip. Early diagnosis and treatment is critical to provide the best pos.i.le functional outcome. Persistence of hip dysplasia into adolescence and adulthood may result in abnormal gait, decreased strength and increased rate of degenerative hip and knee joint disease. Des.i.e efforts to recognize and treat all cases of DDH soon after birth, diagnosis.i. delayed in some children, and outcomes deteriorate with increasing delay of presentation. Different screening programs for DDH were implicated. The sus.i.ion is raised based on a physical examination soon after birth. Radiography and ultrasonography are used to confirm the diagnosis. The role of other imaging modalities, such as magnetic resonance imaging, is s.i.l undetermined; however, extensive research is underway on this subject. Treatment depends on the age of the patient and the reducibility of the hip joint. At an early age and up to 6 mo, the main treatment is an abduction brace like the Pavlik harness. if this fails, closed reduction and s.i.a cas.i.g is usually done. After the age of 18 mo, treatment usually consists of open reduction and hip reconstruction surgery. Various treatment protocols have been proposed. We summarize the current practice for detection and treatment of DDH, emphasizing updates.i. screening and treatment during the last two decades.

A golden age for heavy quarkonium physics dawned at the turn of this century, initiated by the confluence of exciting advances.i. quantum chromodynamics （QCD） and an explosion of related experimental activity. The subsequent broad spectrum of breakthroughs, surprises, and continuing puzzles had not been anticipated. in that period, the BEs.i.program concluded only to give birth to BEs.i.; the B-factories and CLEO-c flourished; quarkonium production and polarization measurements at HERA and the Tevatron matured; and heavyion collisions at RHiC opened a window on the deconfinement regime. Recently also ATLAs, CMs and LHCb started to contribute to the field. For an extensive presentation of the status of heavy quarkonium physics, the reader is referred to several reviews [1-8]. This note focuses on experimental developments.i. heavy quarkonium spectroscopy with very few theoretical comments. some other comments on pos.i.le theoretical interpretations of the states not predicted by the quark model are presented in the mini-review on non qq-states.
