This study investigates the variability in the temporal alignment of turn initiations and its relationship to the entrainment and power structure between the interlocutors. The data come from spontaneous, task-oriented human-human dialogues in Standard American English, and focus on singleword turn-initial utterances. The descriptive and quantitative analysis of the data show that an emergent a...

Experimental turn by turn beam position measurements were performed in order to investigate the non-linear beam dynamics in Super-ACO. The aim of these experiments is to get a better understanding of the aperture limiting effects of non-linearities and to check the model used in tracking studies. The amplitudedependent tune shift measurements allow to highlight a strong octupolar-like component...

amyloid-β (aβ) self-assembly into cross-β amyloidfibrils is implicated in a causative role in alzheimer’s disease pathology.uncertainties persist regarding the mechanisms of amyloid self assembly and the role of metastable prefibrillar aggregates. aβ fibrilsfeature a sheet-turn-sheet motif in the constituent β-strands; as such, turn nucleation has been proposed as a rate-limiting step in the se...

Location based applications have gained much attention in recent years mainly with the advent of mobile devices such as smart-phones, PC-tablets, and netbooks. These devices facilitate the position data collection and allows some applications to make use of this data. For instance, mobile search is taking advantage of the local information to improve the user experience. Among the most common l...

Xiaobiao Huang Beam Diagnosis and Lattice Modeling of the Fermilab Booster A realistic lattice model is a fundamental basis for the operation of a synchrotron. In this study various beam-based measurements, including orbit response matrix (ORM) and BPM turn-by-turn data are used to verify and calibrate the lattice model of the Fermilab Booster. In the ORM study, despite the strong correlation b...

1.1.1 Introduction For linear accelerators, a single bunch instability of a positron bunch due to electrons created by ionization of the residual gas was discussed in Ref. [1], where a coherent oscillation of both electrons and positrons grows from any small initial perturbation of the bunch distribution, e.g. from the statistical fluctuations due to the finite number of beam particles. This in...
