CP Violation in Top Physics at the NLC
Top quark is extremely sensitive to non-standard CP violating phases. General
strategies for exposing different types of phases at the NLC are outlined. SUSY
phase(s) cause PRA in . The transverse polarization of the in
the reaction is extremely sensitive to a phase from the charged
Higgs sector. Phase(s) from the neutral Higgs sector cause appreciable dipole
moment effects and lead to sizable asymmetries in and

Pure Leptonic Radiative Decays and the Annihilation Graph
Pure leptonic radiative decays of heavy-light mesons are calculated using a
very simple non-relativistic model. Dominant contribution originates from
photon emission from light initial quark. We find
and . The importance of these reactions to
clarify the dynamics of the annihilation graph is emphasized.Comment: 7 pages, LaTeX, 3 figure
Identifying Parkinson’s Patients: A Functional Gradient Boosting Approach
Parkinson’s, a progressive neural disorder, is difficult to identify due to the hidden nature of the symptoms associated. We present a machine learning approach that uses a definite set of features obtained from the Parkinson’s Progression Markers Initiative (PPMI) study as input and classifies them into one of two classes: PD (Parkinson’s disease) and HC (Healthy Control). As far as we know this is the first work in applying machine learning algorithms for classifying patients with Parkinson’s disease with the involvement of domain expert during the feature selection process. We evaluate our approach on 1194 patients acquired from Parkinson’s Progression Markers Initiative and show that it achieves a state-of-the-art performance with minimal feature engineering
