Los agujeros negros gigantes en los centros de las galaxias no deberían poder fusionarse, pero lo hacen. Los científicos sugieren que una forma inusual de materia oscura puede ser la solución. Un artículo de Jonathan O’Callaghan. Historia original reimpresa con permiso de Quanta Magazine, una publicación editorialmente independiente respaldada por la Fundación Simons. En esta simulación, se ven corrientes de gas de colores brillantes alrededor de un par de agujeros negros supermasivos en órbita.

1 Introduction Microstructure noise (MN) is the difference between a market price and the efficient price which would be observed if markets had perfect characteristics. MN has many sources, which we separate into the two components noted in the seminal paper by Hansen and Lunde (2006) and amplified by Ait-Sahalia et al. (2011).

The 2023 wildfire season in Canada was unprecedented in its scale and intensity, spanning from mid-April to late October and across much of the forested regions of Canada. Here, we summarize the main causes and impacts of this exceptional season. The record-breaking total area burned (~15 Mha) can be attributed to several environmental factors that converged early in the season: early snowmelt, multiannual drought conditions in western Canada, and the rapid transition to drought in eastern Canada. Anthropogenic climate change enabled sustained extreme fire weather conditions, as the mean May–October temperature over Canada in 2023 was 2.2 °C warmer than the 1991–2020 average. The impacts were profound with more than 200 communities evacuated, millions exposed to hazardous air quality from smoke, and unmatched demands on fire-fighting resources. The 2023 wildfire season in Canada not only set new records, but highlights the increasing challenges posed by wildfires in Canada. The record-breaking 2023 wildfire season in Canada ( ~ 15 Mha burned) was enabled by early snowmelt, drought, and extreme weather. It had profound impacts that included evacuation of >200 communities, millions exposed to hazardous smoke, and a strain on fire-fighting resources.

AbstractSingle cell spatial interrogation of the immune-structural interactions in COVID −19 lungs is challenging, mainly because of the marked cellular infiltrate and architecturally distorted microstructure. To address this, we develop a suite of mathematical tools to search for statistically significant co-locations amongst immune and structural cells identified using 37-plex imaging mass cytometry.

Here’s a business problem: your company has multiple, very large customers, each with hundreds of users that have the potential to submit cases for support. When customer service personnel or management want to review the history of cases for a customer, they will see a very long related list – hundreds, if not thousands, of cases on the account record. Instead, they will want to quickly see cases with different statuses so they can analyze the health of the customer in question.
