The Sun's magnetic (Hale) cycle and 27 day recurrences in the $aa$ geomagnetic index

no code implementations7 Jan 2021 S. C. Chapman, S. W. McIntosh, R. J. Leamon, N. W. Watkins

We re-engineer the Sargent(1985, 2021) R27 index and combine it with our epoch analysis to obtain a high time resolution parameter for 27 day recurrence in aa, <acv(27)>.

Global Wheat Head Detection (GWHD) dataset: a large and diverse dataset of high resolution RGB labelled images to develop and benchmark wheat head detection methods

4 code implementations25 Apr 2020 E. David, S. Madec, P. Sadeghi-Tehran, H. Aasen, B. Zheng, S. Liu, N. Kirchgessner, G. Ishikawa, K. Nagasawa, M. A. Badhon, C. Pozniak, B. de Solan, A. Hund, S. C. Chapman, F. Baret, I. Stavness, W. Guo

Detection of wheat heads is an important task allowing to estimate pertinent traits including head population density and head characteristics such as sanitary state, size, maturity stage and the presence of awns.

We identify multi-wavelength counterparts to 1, 147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio$+$machine-learning method trained on a large sample of ALMA-identified submillimeter galaxies (SMGs), including 260 SMGs identified in the AS2COSMOS pilot survey.
