Segmentation of Coronal Holes Using Active Contours Without Edges [PDF]
, 2016 An application of active contours without edges is presented as an efficient and effective means of extracting and characterizing coronal holes. Coronal holes are regions of low-density plasma on the Sun with open magnetic field lines. As the source of the fast solar wind, the detection and characterization of these regions is important for both ...

Coronal Dynamic Activities in the Declining Phase of a Solar Cycle [PDF]
, 2016 It has been known that some solar activity indicators show a double-peak feature in their evolution through a solar cycle, which is not conspicuous in sunspot number. In this letter, we investigate the high solar dynamic activity in the declining phase of the sunspot cycle by examining the evolution of polar and low latitude coronal hole areas and the ...

Addiction, EarlyView.Abstract Aims This study aimed to quantify the population‐level impact of a large‐scale opioid agonist treatment (OAT) program on suicide‐related mortality among people with opioid use disorder (OUD) in New South Wales (NSW), Australia. Design This is the first study to use dynamic mathematical modeling to explore the population‐level impact of OAT on ...

Addiction, EarlyView.Abstract Background and Aims The use of new synthetic opioids, such as the highly potent 2‐benzylbenzimidazoles (i.e. nitazene) drugs, is a global health concern because of their increased risk of fatal overdose. In the early 2020s, nitazene analogues were linked to significant numbers of overdoses in the United States.

Relation of coronal rain originating from coronal condensations to interchange magnetic reconnection [PDF]
, 2020 Using extreme-ultraviolet images, we recently proposed a new and alternative formation mechanism for coronal rain along magnetically open field lines due to interchange magnetic reconnection. In this paper we report coronal rain at chromospheric and transition region temperatures originating from the coronal condensations facilitated by reconnection ...

The Politics of Revenge: Revanchist Populism in San Francisco and the United States
Antipode, EarlyView.Abstract This article offers a conjunctural analysis of revanchism in San Francisco across scale. Over the past decade, conservative politicians, media, oligarchs, and organisations have emphasised immigration, homelessness, bureaucratic inefficiency, the opioid epidemic, diversity initiatives, and criminal justice reform to frame San Francisco as a ...
