PURPOSE To evaluate the effectiveness of internal fixation versus cone hemiarthroplasty for the treatment of unstable intertrochanteric fractures in elderly patients. METHODS The choice of treatment was based on the year of admission: between 2001 and 2003, 42 patients (mean age, 73 years) underwent cone hemiarthroplasty using a cementless press fit(More)
We draw a parallel between hashtag time series and neuron spike trains. In each case, the process presents complex dynamic patterns including temporal correlations, burstiness, and all other types of nonstationarity. We propose the adoption of the so-called local variation in order to uncover salient dynamical properties, while properly detrending for the(More)
Citation: Sanli C and Lambiotte R (2015) Temporal pattern of online communication spike trains in spreading a scientific rumor: how often, who interacts with whom? Front. Phys. 3:79. We study complex time series (spike trains) of online user communication while spreading messages about the discovery of the Higgs boson in Twitter. We focus on online social(More)
In this paper, we propose a methodology quantifying temporal patterns of nonlinear hashtag time series. Our approach is based on an analogy between neuron spikes and hashtag diffusion. We adopt the local variation, originally developed to analyze local time delays in neuron spike trains. We show that the local variation successfully characterizes nonlinear(More)
