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
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 , -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
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
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
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
The College Application Essay Mediating Inequality Along the Path to Higher Education
This dissertation examines inequality and access in the college admissions process and, in particular, via the college application essay. With a research design and analysis sampling documents from multiple stakeholders in the college admissions process, this research considers how students with diverse histories of preparation for higher education interact with actors relevant to the admissions process in their college admissions essays. This research project ultimately asks how the college essay process (its importance, the preparation, and ultimate writing) mediates inequality in admission to higher education. Essays were collected from students at one large public university and one small private liberal arts university. These were analyzed alongside university admissions requirements and college preparatory agency information. Analyses showed that all student essays interacted with the institutional expectations and presented an awareness of the need to write for their audience. Students addressed their audience more and less directly, by conveying challenges they overcame and describing the personal growth that came from those challenges. Differences in essays by students across public and private universities emerged in how the students approached challenges and development. For example, first-generation college students and those who did not participate in college preparatory activities devoted more words to describing the challenge itself, whereas their non-first-generation peers and those that were exposed to college preparatory work devoted more attention to exploring the development of their passions. This study sheds light on how students use the college essay process to negotiate their understanding of higher education and their potential place in it, in relation to numerous messages they have received. That said, barriers to higher education access remain. The findings can help researchers consider innovative designs for studying inequality and for considering practices of educators, policy makers, and families to better understand the college process
