Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Using Extreme Value Theory for Determining the Probability of Carrington‐Like Solar Flares [PDF]

, 2016
By their very nature, extreme space weather events occur rarely, and therefore, statistical methods are required to determine the probability of their occurrence.

Impact of particulate matter exposure on melanoma risk: A multicentre case–control study

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Long‐term exposure to higher levels of PM10 and PM2.5 may have a protective effect against melanoma, potentially due to the reduction in ultraviolet radiation. Abstract Background The relationship between particulate matter (PM) exposure and melanoma risk remains largely unexplored.

Spatio-temporal Dynamics of Sources of Hard X-Ray Pulsations in Solar Flares [PDF]

, 2016
We present a systematic analysis of the spatio-temporal evolution of sources of hard X-ray (HXR) pulsations in solar flares. We concentrate on disk flares whose impulsive phases are accompanied by a series of more than three successive peaks (pulsations)

On the Optimal Prediction of Extreme Events in Heavy‐Tailed Time Series With Applications to Solar Flare Forecasting

Journal of Time Series Analysis, EarlyView.
ABSTRACT The prediction of extreme events in time series is a fundamental problem arising in many financial, scientific, engineering, and other applications. We begin by establishing a general Neyman–Pearson‐type characterization of optimal extreme event predictors in terms of density ratios.

Solar Flare X‐Ray Impacts on Long Subionospheric VLF Paths

Space Weather, 2021
Solar flares increase the electron number concentration in the daytime ionosphere, potentially affecting radiowave propagation over several frequency ranges.

Konus-Wind and Helicon-Coronas-F Observations of Solar Flares

, 2014
Results of solar flare observations obtained in the Konus-Wind experiment from November, 1994 to December, 2013 and in the Helicon Coronas-F experiment during its operation from 2001 to 2005, are presented.

A primitive asteroid that lived fast and died young sampled by a xenolith in the Cold Bokkeveld CM2 carbonaceous chondrite

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 464-483, March 2025.
Abstract Xenoliths in carbonaceous chondrites include lithologies that are unrepresented in the meteorite record and so are a rich source of information on asteroid diversity. Cold Bokkeveld is a CM2 regolith breccia that contains both hydrous and anhydrous lithic clasts. Here, we describe a hydrous clast with a fine‐grained rim.

Solar Flares: The Gradual Phase [PDF]

Solar Physics, 1989
AbstractOne has to distinguish between two kinds of the gradual phase of flares: (1) a gradual phase during which no energy is released so that we see only cooling after the impulsive phase (a confined flare), and (2) a gradual phase during which energy release continues (a dynamic flare).The simplest case of (1) is a single-loop flare which might ...

The Association Between Urbanisation and Household Food Security in Nigeria

Maternal &Child Nutrition, EarlyView.
This paper focuses on the nexus between urbanisation and household food security in the context of Nigeria. The study uses night‐time light intensity as a proxy for urbanisation to capture the variation in urbanisation to estimate its relationship to household food security.
