Boulder of orbicular rapakivi in Taivassalo, southwestern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1983
A boulder of an orbicular rapakivi was found in Taivassalo, close to the southern contact of the Vehmaa rapakivi area in southwestern Finland. Many features, e.g.

A computational tool (H-MAGMA) for improved prediction of brain disorder risk genes by incorporating brain chromatin interaction profiles

open access: yesNature Neuroscience, 2020
Most risk variants for brain disorders identified by genome-wide association studies reside in the noncoding genome, which makes deciphering biological mechanisms difficult.

Aging in magma rheology

open access: yesScientific Reports, 2022
AbstractAging, change in property depending on the elapsed time from preparation, is known to affect the rheological behavior of various materials. Therefore, whether magma ages must be examined to characterize potentially widespread volcanic phenomena related to the transition from rest to flow.

Magma Fracking Beneath Active Volcanoes Based on Seismic Data and Hydrothermal Activity Observations

open access: yesGeosciences, 2020
Active volcanoes are associated with microearthquake (MEQ) hypocenters that form plane-oriented cluster distributions. These are faults delineating a magma injection system of dykes and sills.

The Magma Algebra System I: The User Language

open access: yesJournal of symbolic computation, 1997
In the first of two papers on MAGMA , a new system for computational algebra, we present the MAGMA language, outline the design principles and theoretical background, and indicate its scope and use.

MAGMA: Generalized Gene-Set Analysis of GWAS Data

open access: yesPLoS Comput. Biol., 2015
By aggregating data for complex traits in a biologically meaningful way, gene and gene-set analysis constitute a valuable addition to single-marker analysis. However, although various methods for gene and gene-set analysis currently exist, they generally

Image-based modelling of lateral magma flow: the Basement Sill, Antarctica [PDF]

open access: yesRoyal Society Open Science, 2017
The McMurdo Dry Valleys magmatic system, Antarctica, provides a world-class example of pervasive lateral magma flow on a continental scale. The lowermost intrusion (Basement Sill) offers detailed sections through the now frozen particle microstructure of

Eruptible magma [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
For those who remember the classic disaster-docudrama Supervolcano (BBC-Discovery Channel 2005), the adjective “eruptible” is likely to ring a bell. Set in the near future and generally quite scientifically literate, the movie envisions volcanologists trying desperately to evaluate the near-term threat posed by the giant Yellowstone magmatic system.

Metal Injection Molding (MIM) of NdFeB Magnets

open access: yesEPJ Web of Conferences, 2014
Due to the increased and unstable prices for Rare Earth elements there are activities to develop alternative hard magnetic materials. Reducing the amount of material necessary to produce complex sintered NdFeB magnets can also help to reduce some of the ...
