About the helix structure of the Lund string

The helix structure of the Lund string, first derived from studies devoted to the emission of soft gluons at the end of the parton cascade, may be at the origin of a part of the 'correlations' observed in multidimensional analyses of the Bose-Einstein effect. It is found that a helix structure of the string corresponding to an emission of soft gluons from a regularly spinning source is supported by the data, more precisely by the inclusive single-particle spectra measured in the hadronic decay of Z$^0$

Helix string fragmentation and charged particle correlations with ATLAS

Correlations between charged particles provide important insight about the hadronization process. The analysis of the momentum difference between charged hadrons in $pp$, $p$-lead, and lead-lead collisions at LHC is performed by the ATLAS Collaboration in order to study the dynamics of hadron formation. The spectra of correlated hadron chains are explored and compared to the predictions based on the quantized fragmentation of a three dimensional QCD helix string. This provides an alternative view of the two-particle correlation phenomenon typically attributed to the Bose-Einstein interference.Comment: 5 pages, 3 figures. Proceedings ISMD202

Comparative assessment of prognosis of the stop stimulus and trapezoidal rotation programs

For prognosis of the diagnostic possibilities of the stop stimulus and trapezoidal rotation programs with respect to the nystagmus response, 24 healthy young persons with normal auditory and vestibular analysers were studied experimentally. The trapezoidal program more accurately reflects the function and tone balance of the vestibular system than the stop stimulus program and causes the subject no unpleasant sensations during the study. Some optimum couples, acceleration and armchair rotation rate, necessary for effective deviation of the cupuloendolymphatic system were determined. The maximum angular velocity of the slow nystagmus component was more informative than nystagmus duration. The trapezoidal program is recommended for otoneurological practice and the maximum angular velocity of the slow nystagmus component as the basic index

Socialist/Postsocialist Studies and the Global Left: A Critical Commentary

This commentary addresses the marginal presense of authors, subjects, and issues focused on former socialist countries in Eastern and Central Europe, the Balkans and the former Soviet Union in "socialist studies" produced in Western English-language based academic journals, as well as the so-called "global political Left" these publications support. The commentary suggests that the gap is epistemological, emotional, and serving to protect conversations about "socialsim" from the deep critique and interogation of socialist theories, utopias, and practices generated in the emerging field of "postsocialist studies" originating in former socialist states and societies assocaited with a geopolitical "East.

Dusty but Mighty: Using Radio in the Critical Media Literacy Classroom

In a culture dominated by images, what is the capacity of radio-making to enact the ideals and meet the objectives of critical medial literacy education that empowers learners and expands democracy? This article conceptualizes a radio-based critical media literacy approach drawing upon a course project called “Borderless Radio,” where fifty-two students in a large urban Canadian university produced short radio programs narrating how they view and experience “multiculturalism.” Radio making in the classroom is soundscaping that politicizes intimacy, disrupts hegemonic discourses, and allows for teaching and learning to transgress; yet it also illuminates the ways in which self-positionality poses limitations to media literacy education that seeks to link local classrooms to a global world

The ATLAS Tracking Geometry Description

Track reconstruction requires a detector geometry description for the usage in track extrapolation processes and material effects integration during track finding and track fitting. Since, in general, the more realistic detector description used in full detector simulation causes an unacceptable increase of CPU time consumption when being used in track reconstruction, the reconstruction geometry is realised as a simplified description of the actual detector layout. This documents presents the data classes of the newly developed ATLAS reconstruction geometry and describes its building process for the ATLAS CSC detector layouts. Additionally a comparison of the material budget described by the reconstruction geometry with one used in full detector simulation will be presented for the Inner Detector and the Calorimeter

Asymptotic stability and blow up for a semilinear damped wave equation with dynamic boundary conditions

In this paper we consider a multi-dimensional wave equation with dynamic boundary conditions, related to the Kelvin-Voigt damping. Global existence and asymptotic stability of solutions starting in a stable set are proved. Blow up for solutions of the problem with linear dynamic boundary conditions with initial data in the unstable set is also obtained
