Abstract Intense magnetic storms pose a systemic threat to the electric power grid. In this study we examined solar/interplanetary causes of such storms, their peak theoretical and observed intensities, occurrence frequency. Using coronal mass ejection (CME) solar wind data, selected 18 intense from 1996 2021 with disturbance storm time (Dst) index less than – 200 nT analyzed events conditions ...

nevoid basal cell carcinoma syndrome (bcns) is an autosomal dominant inherited disorder. multiple organ systems may be affected in this syndrome including abnormalities of the skin, skeletal system, genitourinary system and central nevus system. in this report, we present a case of nevoid basal cell carcinoma syndrome in a 26-year-old male patient. the patient had multiple odontogenic keratocys...

Most of the statistical social network analysis methods rely on a fixed network structure. Earlier methods of dyadic statistical analysis manage to provide quantification on degrees of mutuality between actors and triadic analysis does a step forward allowing validation of theories of balance and transitivity about specific components of a network. Each of these constitutes a subset of a more g...

The prior quote is from a recent issue of Science with a special section on the topic of developmental timing. The temporal events that guide development are key parts of the puzzle of contemporary molecular genetics. Genes are known to turn on at certain times in development; microRNAs show temporaland tissuespecific patterns of gene expression (cf. Carrington & Ambros, 2003); and genes activa...

This chapter treats statistical methods for network evolution. It is argued that it is most fruitful to consider models where network evolution is represented as the result of many (usually non-observed) small changes occurring between the consecutively observed networks. Accordingly, the focus is on models where a continuous-time network evolution is assumed although the observations are made ...

A shocklike transition at 2003.37 from quasi-periodic flows to increasingly fast flows was observed by Voyager 2 (V2) near 70 AU. The transition was related to the appearance of coronal holes near the solar equatorial plane on Carrington rotation (CR) 1994. Several important features (two cycles of quasi-periodic variations in V and B, a shock, a merged interaction region (MIR) with strong magn...

Using the observations from Michelson Doppler Imager (MDI) onboard Solar and Heliospheric Observatory (SOHO), we develop a computational algorithm to automatically identify the bipolar magnetic regions (BMRs) in the active regions, and then study their statistical properties. The individual magnetic (positive or negative) pole of the BMR is determined from the region with an absolute strength a...

We have investigated the relationship between magnetic activity and coronal structures using soft X-ray data from the Yohkoh soft X-ray telescope and magnetic field data from the Kitt Peak Solar Observatory for the period of 1991–2001 and EUV data from the Solar and Heliospheric Observatory EUV Imaging Telescope for 1996–2001. The data are reduced to Carrington synoptic maps, which reveal two t...

COMMUNICATIONSTO THE EDITOR 615 misdiagnosed as diffuse alveolar damage or fibrosing alveolitis. Dr. Carrington has re-reviewed the slides and agrees that this is an example of eosinophilic pneumonia with an unusual degree of bronchiolitis obliterans. The patient has also been included in another report4 as an example of acute fibrosing alveolitis. It is recognized that patients with rheumatoid...
