A novel neural network-based approach to derive a geomagnetic baseline for robust characterization of geomagnetic indices at mid-latitude

Autor: Kieokaew, Rungployphan, Haberle, Veronika, Marchaudon, Aurélie, Blelly, Pierre-Louis, Chambodut, Aude

Geomagnetic indices derived from ground magnetic measurements characterize the intensity of solar-terrestrial interaction. The \textit{Kp} index derived from multiple magnetic observatories at mid-latitude has commonly been used for space weather ope

Weak Diffusive Stability of Roll Solutions at the Zigzag Boundary

Autor: Chowdhary, Abhijit, Haberle, Mason, Ofori-atta, William, Wu, Qiliang

Roll solutions at the zigzag boundary, typically selected by patterns and defects in numerical simulations, are shown to be nonlinearly stable. This result also serves as an example that linear decay weaker than the classical diffusive decay, togethe

The Indo–Pacific Pollen Database – a Neotoma constituent database

Autor: A. V. Herbert, S. G. Haberle, S. G. A. Flantua, O. Mottl, J. L. Blois, J. W. Williams, A. George, G. S. Hope

Publikováno v: Climate of the Past, Vol 20, Pp 2473-2485 (2024)

The Indo–Pacific Pollen Database (IPPD) is the brainchild of the late professor Geoffrey Hope, who gathered pollen records from across the region to ensure their preservation for future generations of palaeoecologists. This noble aim is now being f

Temperature dependence of nitrate uptake kinetics in Triticum aestivum L. and Triticum dicoccon Schrank cultivars

Autor: Ivana Raimanová, Jana Wollnerová, Jan Haberle, Svoboda Pavel

Publikováno v: Czech Journal of Genetics and Plant Breeding, Vol 60, Iss 4, Pp 212-222 (2024)

Temperature is a key parameter that influences the uptake and subsequent utilization of nitrogen by plants. Both suboptimal and supraoptimal temperatures can impair nutrient uptake. The close relatives of bread wheat provide a possible source for bre

Diurnal and Seasonal Mapping of Martian Ices With EMIRS

Autor: Stcherbinine, Aurélien, Edwards, Christopher S., Smith, Michael D., Wolff, Michael J., Haberle, Christopher, Tunaiji, Eman Al, Smith, Nathan M., Saboi, Kezman, Anwar, Saadat, Lange, Lucas, Christensen, Philip R.

Publikováno v: Geophysical Research Letters, 50, e2023GL103629

Condensation and sublimation of ices at the surface of the planet is a key part of both the Martian H$_2$O and CO$_2$ cycles, either from a seasonal or diurnal aspect. While most of the ice is located within the polar caps, surface frost is known to

Communication Bounds for Convolutional Neural Networks

Autor: Chen, Anthony, Demmel, James, Dinh, Grace, Haberle, Mason, Holtz, Olga

Publikováno v: PASC '22: Proceedings of the Platform for Advanced Scientific Computing Conference June 2022 Article No. 1 Pages 1-10

Convolutional neural networks (CNNs) are important in a wide variety of machine learning tasks and applications, so optimizing their performance is essential. Moving words of data between levels of a memory hierarchy or between processors on a networ
