Search for magnetic monopoles in polar volcanic rocks [PDF]

Phys. Rev. Lett. 110, 121803 (2013), 2013
For a broad range of values of magnetic monopole mass and charge, the abundance of monopoles trapped inside the Earth would be expected to be enhanced in the mantle beneath the geomagnetic poles. A search for magnetic monopoles was conducted using the signature of an induced persistent current following the passage of igneous rock samples through a ...

Geoarchaeological characterisation of a Younger Dryas site in the Alpine uplands: Cornafessa rock shelter (Italy)

Geoarchaeology, Volume 38, Issue 1, Page 35-56, January/February 2023., 2023
Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

The analysis of volcanic activity influences at the lower and middle part of Sentolo Formation, Kulon Progo using petrographic method

MATEC Web of Conferences, 2018
The research area is a part of South Serayu Mountain zone, specifically Bregada Kulon Progo. The Bregada Kulon Progo is a product of volcanic activity in the past, which can be seen by the volcanic rock called Old Andesite Formation.

Rhyolitic Ash Promoting Organic Matter Enrichment in a Shallow Carbonate Platform: A Case Study of the Maokou Formation in Eastern Sichuan Basin

Frontiers in Earth Science, 2022
Volcanic ash improves the amount of nutritive elements in the lake and ocean, but it is not fully understood how volcanic ash influences the total organic matter content (TOC) and bio-precursor, and the scope.

Direct numerical simulation of “fountain filling box” flow with a confined weak laminar plane fountain

Heat Transfer, Volume 52, Issue 1, Page 193-215, January 2023., 2023
Abstract A “fountain filling box” flow produced by discharging a weak laminar plane fountain in a confined open channel is studied numerically. Two‐dimensional direct numerical simulations were performed for weak plane fountains. The development of the fountain flow experiences five stages; the initial upflow and the subsequent downflow after the ...

Reservoir characteristics in the Cretaceous volcanic rocks of Songliao Basin, China: A case of dynamics and evolution of the volcano-porosity and diagenesis

Energy Exploration & Exploitation, 2019
To explain the strong spatial heterogeneity of volcanic reservoirs porosity in the Songliao Basin and provide new ideas for predicting good volcanic reservoirs in other similar basins, the relationship between the pore evolution process and lithology of ...

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Geochemical discrimination and characteristics of magmatic tectonic settings; a machine learning-based approach [PDF]

, 2017
Geochemically discriminating between magmatism in different tectonic settings remains a fundamental part of understanding the processes of magma generation within the Earth's mantle. Here, we present an approach where machine-learning (ML) methods are used for quantitative tectonic discrimination and feature selection using global geochemical datasets ...

Prebiotic Interconversion of Pyruvate and Lactate over Zeolite‐Supported Ni Catalyst

Angewandte Chemie, EarlyView.
Synthetic zeolite Y‐supported Ni mineral can catalyze the interconversion of metabolically crucial pyruvate and lactate under hydrothermal vent conditions, which could pave the way for the modern biological process by lactate dehydrogenase and nicotinamide adenine dinucleotide.
