A neural-network-based method for generating synthetic 1.6 µm near-infrared satellite images
Authors: Baur Florian , Scheck Leonhard , Stumpf Christina , Köpken-Watts Christina , Potthast Roland 
Published: November 2023

Abstract. In combination with observations from visible satellite channels, near-infrared channels can provide valuable additional cloud information, e.g. on cloud phase and particle sizes, which is also complementary to the information content of thermal infrared channels. Exploiting near-infrared channels for operational data assimilation and model evaluation requires a sufficiently fast and accurate forward operator. This study presents an extension to the method for fast satellite image synthesis (MFASIS) that allows for simulating reflectances of the 1.6 µm near-infrared channel based on a computationally efficient neural network with the same accuracy that has already been achieved for visible channels. For this purpose, it is important to better represent vertical variations in effective cloud particle radii, as well as mixed-phase clouds and molecular absorption in the idealized profiles used to train the neural network. A new approach employing a two-layer model of water, ice and mixed-phase clouds is described, and the relative importance of the different input parameters characterizing the idealized profiles is analysed. A comprehensive data set sampled from Integrated Forecasting System (IFS) forecasts together with different parameterizations of the effective water and ice particle radii is used for the development and evaluation of the method. Further evaluation uses a month of ICOsahedral Non-hydrostatic development based on version 2.6.1 (ICON-D2) hindcasts with effective radii directly determined by the two-moment microphysics scheme of the model. In all cases, the mean absolute reflectance error achieved is about 0.01 or smaller, which is an order of magnitude smaller than typical differences between reflectance observations and corresponding model values. The errors related to the imperfect training of the neural networks present only a small contribution to the total error, and evaluating the networks takes less than a microsecond per column on standard CPUs. The method is also applicable for many other visible and near-infrared channels with weak water vapour sensitivity.

Abstract. The present work proposes a prediction model of significant wave height (SWH) and average wave period (APD) based on variational mode decomposition (VMD), temporal convolutional networks (TCNs), and long short-term memory (LSTM) networks. The wave sequence features were obtained using VMD technology based on the wave data from the National Data Buoy Center. Then the SWH and APD prediction models were established using TCNs, LSTM, and Bayesian hyperparameter optimization. The VMD–TCN–LSTM model was compared with the VMD–LSTM (without TCN cells) and LSTM (without VMD and TCN cells) models. The VMD–TCN–LSTM model has significant superiority and shows robustness and generality in different buoy prediction experiments. In the 3 h wave forecasts, VMD primarily improved the model performance, while the TCN had less of an influence. In the 12, 24, and 48 h wave forecasts, both VMD and TCNs improved the model performance. The contribution of the TCN to the improvement of the prediction result determination coefficient gradually increased as the forecasting length increased. In the 48 h SWH forecasts, the VMD and TCN improved the determination coefficient by 132.5 % and 36.8 %, respectively. In the 48 h APD forecasts, the VMD and TCN improved the determination coefficient by 119.7 % and 40.9 %, respectively.

Are Placer Platinum Nuggets Formed During Lateritization? The Verdict from the Owendale Alaskan-Uralian Complex in Australia Is an Emphatic No!
Authors: Ma Bocheng , Keays Reid R. 
Published: November 2023

Abstract
The thick laterite developed over platinum group element (PGE)-bearing ultramafic rocks of the Owendale Alaskan-Uralian Complex in New South Wales, Australia, provides an ideal environment in which to address the question of whether Pt-Fe nuggets are formed during lateritization. This is an important issue to settle because Pt-Fe nuggets in alluvial placers and eluvial deposits associated with the Alaskan-Uralian complexes were the world’s major source of Pt prior to the commencement of Pt production from the Bushveld Complex and continue to produce a significant amount of Pt. Some of the Owendale laterites have high Pt but low Cu contents, while others have both high Pt and high Cu contents. Heavy mineral concentrates were prepared from about 1 kg of drill chips from both types of laterites. Only five of the 61 samples processed contained any platinum group minerals (PGMs) greater than 5 μm in size, even though many of the samples contained more than 1 g/t Pt. The largest PGM found was about 100 μm long, and the majority were &lt;20 μm. The bulk of the PGMs recovered were zoned PGMs consisting of a core of isoferroplatinum mantled by tetraferroplatinum with an outer rim of tulameenite; many of these zoned PGMs are encased in hematite grains that often have high Pt contents and appear to be pseudomorphs after the PGMs. The textural evidence indicates that at least half of the primary PGMs in the ultramafic protoliths to the laterites were destroyed during weathering and that the liberated PGEs could have been available for the formation of PGM nuggets. However, despite the large amount of PGEs liberated during the destruction of the primary PGMs, no evidence was found for the neogenic growth of PGE nuggets. Rather, the Pt liberated during the destruction of the PGMs appears to have only traveled distances of micrometers to tens of centimeters to form Pt nanoparticles or Pt oxides or to be absorbed/adsorbed by the Fe oxide hosts.
“The Heart Has Its Reasons”
Authors: Fair John D. 
Published: November 2023

Abstract
At age thirty-eight, Colorado professor Conrad Cotter, who led a sedentary lifestyle, suffered two heart attacks. Despite his family history of heart disease, he recuperated by quitting smoking, reducing his weight, relocating to a sea-level city, and exercising regularly. Curiously, he adopted powerlifting, an activity suspected of unduly straining the heart, for rehabilitation. After participating in it for a decade, he was not only stronger and breaking numerous age-group records but seemingly healthier. Cotter's fortunes changed when he retired from competition in the early 1980s, assumed stressful administrative responsibilities, and returned to a sedentary lifestyle. Confronted with multiple major crises stemming from his role as president of the United States Powerlifting Federation, including its break-up into several federations, a ruinous lawsuit, and finally loss of his livelihood, Cotter seemed ill-prepared to cope with them. It was mainly stress that led to his demise from a heart attack in 1990 at sixty-two.

Published: November 2023

Abstract
CIPHER: Hip Hop Interpellation is a global hip hop knowledge mapping project using ethnographic, digital, and arts practice research methods to better understand the emergences and flows of the culture's deeply local yet immanently global intertextualities. In this collaborative article, we network and develop ideas from six of CIPHER's global hip hop researchers, elaborating the project in method as well as theory. In so doing, we model our community-engaged CIPHER method of tracking thematic, conceptual, and archetypal relationships, presenting preliminary findings in four interrelated case studies: examples of hip hop knowledge transfer that evidence hip hop's generative glocal dialogue.
“The New Superstition, the New Tyranny”: The Ethics and Contexts of John Cowper Powys's Antivivisection
Authors: Taylor Felix 
Published: November 2023

Abstract
This article examines the antivivisectionist writings of British novelist and philosopher John Cowper Powys (1872–1963) during the 1930s and 1940s. Powys's opposition to the widespread practice of animal experimentation, both in his fiction and his contributions to activist newspapers, has been noted by critics to have prefigured the modern animal rights movement. On the surface, his writings on the subject display an unnuanced and impassioned outrage, yet on closer inspection, they form a logical piece of Powys's idiosyncratic worldview and to some extent reflect the arguments of “new age” antivivisection campaigns of his time.
