    1. The cost of child poverty is not just borne by the poor. When the expenses related tolost productivity, crime, and poor health are added up, it is estimated that child povertycosts the nation between $800 billion and $1.1 trillion per year. This is vastly higherthan the estimated $90 to $111 billion per year it would take to implement a programpackage that would lift half of children out of poverty.

      The savings indicated here is almost a factor of 10! How can we not be doing this?

      Compare with statistics and descriptions from Why Fewer American Children Are Living in Poverty (New York Times, The Daily, 2022-09-26)

    1. Notably absent from the debris was plastic from nations with lots of plastic pollution in their rivers. This was surprising, says Egger, because rivers are thought to be the source of most ocean plastic. Instead, most of the garbage-patch plastic seemed to have been dumped into the ocean directly by passing ships.This suggests that “plastic emitted from land tends to accumulate along coastal areas, while plastic lost at sea has a high chance of accumulating in ocean garbage patches”, Egger says. The combination of the new results and the finding that fishing nets make up a large proportion of the debris indicates that fishing — spearheaded by the five countries and territories identified in the study — is the main source of plastic in the North Pacific garbage patch.

    1. NETs are also associated with thrombotic events in COVID-19, consisting of platelets, complement (C3) and tissue factor in blood

      Monocyte and neutrophil aggregates with platelets have been identified in COVID-19 patients and correlate with disease severity https://doi.org/10.1055/s-0040-1718732

      Von Willebrand’s factor and ADAMTS13 are also implicated in NET-associated immunothrombosis https://doi.org/10.3389/fimmu.2020.610696 , https://doi.org/10.1002/ctm2.268

      Additionally, NETs have been shown to accumulate and persist in the lungs of severe COVID-19 patients https://doi.org/10.1093/infdis/jiab053 and recruits coagulation Factor XII to promote clotting https://doi.org/10.1101/2020.12.29.424644 .

      This persistence is attributed to poor DNase clearance of NETs https://doi.org/10.1111/all.14746

    1. Effect of step size. The gradient tells us the direction in which the function has the steepest rate of increase, but it does not tell us how far along this direction we should step.

      That's the reason why step size is an important factor in optimization algorithm. Too small step can cause the algorithm longer to converge. Too large step can cause that we change the parameters too much thus overstepped the optima.
