Chromospheric Upflow Events Associated with Transition Region Explosive Events
Transition region explosive events are considered to be a manifestation of small scale magnetic reconnection ubiquitously occurring | even in the quiet Sun. In this paper, we report a close association between transition region explosive events and chromo-spheric uppow events seen in H. From a comparison of the Big Bear Solar Observatory (BBSO) H spectrograph data and the Solar and Heliospheric...
متن کاملModelling explosive events in the solar atmosphere
High–resolution ultraviolet (UV) spectra of the outer solar atmosphere show transient brightenings often referred to as explosive events. These are localized regions of small spatial extent that show sudden enhancements in the intensities of lines formed between 20,000 and 200,000 K, accompanied by strong non-gaussian profiles. The present work is an attempt to extract observational consequence...
متن کاملExplosive events in the solar atmosphere
Two examples of explosive events observed with SUMER in transition region spectral lines are reported here; one detected in C iv 1548 Å, in a region within the northern polar coronal hole, and the other in O vi 1032 Å, in an active region. The event measured in C iv lasted ∼ 3 min and extended approximately a region of 8 arc sec along the slit (N-S) and 8 arc sec in the E-W direction. Velocitie...
متن کاملDynamic Frailty and Change Point Models for Recurrent Events Data
Abstract. We present a Bayesian analysis for recurrent events data using a nonhomogeneous mixed Poisson point process with a dynamic subject-specific frailty function and a dynamic baseline intensity func- tion. The dynamic subject-specific frailty employs a dynamic piecewise constant function with a known pre-specified grid and the baseline in- tensity uses an unknown grid for the piecewise ...
متن کاملTime to Recurrent Relapses Analysis in Schizophrenic Patients by Using Recurrent Events Model
Objective: Schizophrenia is to be emphasized due to its high prevalence, severity of symptoms and frequent recurrences. In this study the hazard of recurrence of Schizophrenia was analyzed by using recurrent events models. Materials & Methods: This study was an observational prospective study. Data was gathered from 159 registered schizophrenia patients at Razi Psychiatric Center. The type I...
