Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**
Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Berichte zur Wissenschaftsgeschichte, EarlyView.Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Space Weather Effects on Heart Rate Variations: Sex Dependence
AtmosphereThe effects of solar activity and the accompanying space weather events on human pathological conditions, physiological parameters and other psycho-physiological disturbances have been analyzed in numerous recent investigations.

Surveys in Geophysics, 2007 Among the most puzzling questions in climate change is that of solar-climate variability, which has attracted the attention of scientists for more than two centuries. Until recently, even the existence of solar-climate variability has been controversial - perhaps because the observations had largely involved temporary correlations between climate and ...

Heart Rate Variations During Two Historic Geomagnetic Storms: October and November 2003
AtmosphereThe investigation of the two phenomena of Space Weather, i.e., Forbush decreases in the cosmic ray intensity and geomagnetic storms, is a highly developing field of modern scientific research, since these two phenomena can affect not only technological ...

The Vlasov Equation Cannot Fully Account for Collisionless Shocks
Contributions to Plasma Physics, EarlyView.ABSTRACT It is argued that the Vlasov equation cannot fully account for collisionless shocks since it conserves entropy, while a shock does not. A rigorous mathematical theory of collisionless shocks could require working at the Klimontovich level.

Journal of Biophotonics, EarlyView.An innovative method for noninvasive melanoma diagnosis using the attenuation coefficient from OCT scans and machine learning has been proposed, supporting small sample sizes. When combined with Raman spectroscopy, it can further enhance accuracy. ABSTRACT A multimodal method comprising optical imaging using OCT and molecular detection using Raman ...

Journal of Quaternary Science, EarlyView.ABSTRACT Chronologic and geomorphic evidence of past glaciations is largely recorded in areas at relatively low elevation and/or landscapes defined by high glacial erosion. As a result, data from areas that did not experience significant glacial erosion and the highest elevation locations are lacking from reconstructions of past ice masses.
