摘要

We use Renewal Theory for the estimation and interpretation of the flare rate from the Geostationary Operational Environmental Satellite (GOES) soft X-ray flare catalogue. It is found that, in addition to the flare rate variability with the solar cycles, a much faster variation occurs. The fast variation on time scales of days and hours down to minute scale appears to be comparable with time intervals between two successive flares (waiting times). The detected fast non-stationarity of the flaring rate is discussed in the framework of the previously published stochastic models of the waiting time dynamics.

A novel interpretable model of bathtub hazard rate based on system hierarchy

Yi-Mu Du, C. P. Sun

Summary: This study proposes a model based on hierarchy-structure systems to infer the appearance of bathtub hazard rate (BHR) and provides a theoretical support for BHR in reliability engineering. The model is interpretable and offers applications in predicting HRF shape, inferring structure with lifetime data, and fusing information from different levels.

The Poissonian Origin of Power Laws in Solar Flare Waiting Time Distributions

Markus J. Aschwanden, Jay R. Johnson, Yosia Nurhan

Summary: Numerical simulations in the nonlinear regime predict power-law slopes in the range of 2.0 <= alpha <= 2.5, and observations of solar flares and coronal mass ejections fall within the range of alpha (obs) approximate to 2.1-2.4. Deviations from strict power-law functions are expected due to the variability of the flare event rate lambda(t), and deviations from theoretically predicted slope values alpha occur due to the Poissonian weighting bias of power-law fits.

Diagnosing a Solar Flaring Core with Bidirectional Quasi-periodic Fast Propagating Magnetoacoustic Waves

Yuhu Miao, Dong Li, Ding Yuan, Chaowei Jiang, Abouazza Elmhamdi, Mingyu Zhao, Sergey Anfinogentov

Summary: This study investigated two Quasi-periodic fast propagating (QFP) waves excited by a solar flare, finding that these waves may be periodically excited by the flaring core and exhibit features consistent with the magnetic tuning fork model. The magnetic field inferred with magnetohydrodynamic seismology was consistent with that obtained in the magnetic extrapolation model, indicating that QFP waves are an effective tool for diagnosing both the flaring core and the magnetic waveguide.

Revisiting discrete time age replacement policy for phase-type lifetime distributions

Serkan Eryilmaz

Summary: This paper revisits the discrete time age replacement policy when the system's lifetime is modeled by a discrete phase-type distribution, obtaining necessary conditions for the unique and finite replacement cycle that minimizes the expected cost per unit of time. The results are based on the behavior of the hazard rate and are illustrated for some special discrete phase-type lifetime distributions. Computational results are also presented for the optimal replacement cycle under specific real life setups.

The Decreasing Hazard Rate Phenomenon: A Review of Different Models, with a Discussion of the Rationale behind Their Choice

Elio Chiodo, Giovanni Mazzanti

Summary: The Exponential reliability model is widely adopted in electronic components reliability studies and applications due to its simplicity and memory-less property. The Weibull model is also commonly used, especially when the shape parameter is greater than unity. However, in some cases, a decreasing hazard rate function may be more suitable for describing the true model behind a given failure mechanism. The consequences of mistaken model identification in terms of the hazard rate function behavior are discussed using graphical and numerical case-studies.

A new extension of the modified Weibull distribution with applications for engineering data

M. G. M. Ghazal

Summary: In this study, a novel extension of the modified Weibull distribution called NMW3 distribution is proposed, which exhibits increasing or bathtub-shaped hazard rates, making it beneficial for reliability. The statistical characteristics, including the change points of hazard rate and mean residual lifetime functions, sensitivities of parameters, and the flatness of the bathtub curve, are examined. Through analysis of real data sets, the practical importance of NMW3 distribution is highlighted, showing its superiority over existing extensions of modified Weibull distributions.

Summary: Observations by Metis of a CME reveal that most features seen in visible-light images are also visible in Ly-alpha images, although the latter appear more structured. The estimated expansion velocity of the event is below 140 km/s, suggesting Doppler dimming effects do not significantly reduce Ly-alpha emission from the CME.

Summary: The study aims to predict the galactic cosmic-ray flux for the Solar Orbiter mission in order to evaluate the performance of the Metis coronagraph. By comparing observations with Monte Carlo simulations, it was found that cosmic rays only interact with a fraction of the pixel sample and the overall efficiency for cosmic-ray identification is linked to certain GCR particles. This analysis will continue throughout the Solar Orbiter mission for diagnostic purposes and potential long-term monitoring of the GCR proton flux.

Summary: This letter discusses the first Solar Orbiter (SO)-Parker Solar Probe (PSP) quadrature on January 18, 2021 to investigate the evolution of solar wind from the extended corona to the inner heliosphere. By tracking the same plasma volume observed in the corona with Metis coronagraph on Solar Orbiter to PSP, it allows for the linking of local properties of the solar wind to its coronal source region. The close approach of PSP to the Sun and simultaneous Metis observation of the solar corona provide unprecedented accuracy in inferring the flow-aligned magnetic field and bulk kinetic energy flux density along the coronal current sheet.

Summary: This study explores the solar wind measured by Parker Solar Probe and the coronal source region observed by METIS coronagraph aboard Solar Orbiter. The results indicate that the solar wind properties differ in regions with different magnetic field intensity, with stronger magnetic field regions showing lower bulk flux density and well-developed Alfvenic turbulence, while weaker magnetic field regions exhibit highly intermittent and poorly developed turbulent behavior, possibly due to large magnetic deflections associated with interchange reconnection.
