Droplet activation, separation, and compositional analysis: laboratory studies and atmospheric measurements [PDF]

, 2011
Droplets produced in a cloud condensation nuclei chamber (CCNC) as a function of supersaturation have been separated from unactivated aerosol particles using counterflow virtual impaction.

Deep evolutionary conservation of an intramolecular protein kinase activation mechanism [PDF]

, 2012
DYRK-family kinases employ an intramolecular mechanism to autophosphorylate a critical tyrosine residue in the activation loop. Once phosphorylated, DYRKs lose tyrosine kinase activity and function as serine/threonine kinases.

Archaeometry and Archaeology: preliminary studies of the ceramics from archaeological sites of the upper Madeira river/Rondônia - Brazil.

Brazilian Journal of Radiation Sciences, 2021
In southwest Amazonia, in the region of the Upper Madeira River, Rondônia, archaeological research has shown that communities with diverse cultures co-existed in the pre-colonial past (ca. 1,000 BP). Archaeological sites from this period located on river

Iodine determination in edible algae species using epithermal neutron activation analysis methodology

Brazilian Journal of Radiation Sciences, 2021
Iodine is one of the essential trace elements of much interest in nutritional research being responsible for the production of the thyroid hormones, which has great importance for human metabolism. Edible algae species accumulate iodine from seawater and

Minimax Analysis of Active Learning

J. Mach. Learn. Res., 2014
This work establishes distribution-free upper and lower bounds on the minimax label complexity of active learning with general hypothesis classes, under various noise models. The results reveal a number of surprising facts. In particular, under the noise model of Tsybakov (2004), the minimax label complexity of active learning with a VC class is always
