Metamorphic dynamical quantum phase transition in double-quench processes at finite temperatures [PDF]
Phys. Rev. B 106, 014301 (2022), 2022 By deriving a general framework and analyzing concrete examples, we demonstrate a class of dynamical quantum phase transitions (DQPTs) in one-dimensional two-band systems going through double-quench processes. When this type of DQPT occurs, the Loschmidt amplitude vanishes and the rate function remains singular after the second quench, meaning the ...

Time's arrow, time's cycle: Granulite metamorphism and geodynamics
Mineralogical magazine, 2019 Although the thermal evolution of the mantle before c. 3.0 Ga remains unclear, since c. 3.0 Ga secular cooling has dominated over heat production—this is time's arrow.

Adaptive Metamorphic Testing with Contextual Bandits [PDF]
Journal of Systems and Software (JSS) Vol. 165 (2020) 110574, 2019 Metamorphic Testing is a software testing paradigm which aims at using necessary properties of a system-under-test, called metamorphic relations, to either check its expected outputs, or to generate new test cases. Metamorphic Testing has been successful to test programs for which a full oracle is not available or to test programs for which there are ...

, 2018 We reevaluate the systematics and geologic setting of terrestrial, lunar, Martian, and asteroidal “impactites” resulting from single or multiple impacts. For impactites derived from silicate rocks and sediments, we propose a unified and updated system of

Metamorphism as a covariant transform for the SSR group [PDF]
Bol. Soc. Mat. Mex. 29, 35 (2023), 2023 Metamorphism is a recently introduced integral transform, which is useful in solving partial differential equations. Basic properties of metamorphism can be verified by direct calculations. In this paper we present metamorphism as a sort of covariant transform and derive its most important features in this way.

Towards Automated Metamorphic Test Identification for Ocean System Models [PDF]
arXiv, 2021 Metamorphic testing seeks to verify software in the absence of test oracles. Our application domain is ocean system modeling, where test oracles rarely exist, but where symmetries of the simulated physical systems are known. The input data set is large owing to the requirements of the application domain.

Frontiers in Earth Science, 2021 Intermediate-depth earthquakes (>40 km) have been observed beneath the central Himalayas over decades, with little known about their nature and characteristics.

Automated identification of metamorphic test scenarios for an ocean-modeling application [PDF]
, 2020 Metamorphic testing seeks to validate software in the absence of test oracles. Our application domain is ocean modeling, where test oracles often do not exist, but where symmetries of the simulated physical systems are known. In this short paper we present work in progress for automated generation of metamorphic test scenarios using machine learning ...

ORE GEOLOGY PROBLEMS AND THE HUMAN FACTOR. PART 3. METAMORPHISM AND MESOTHERMAL OREFORMATION
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The relevance of the research. The conditions of the known large mesothermal gold deposits formation into black shales states of different age form the subject of animated discussion which often acquires the signs of substitute and probably therefore the

Earth Sciences Research Journal, 2016 Medium grade metapelites of the Silgará Formation at the Santander Massif (Colombian Andes) have been affected by a medium-pressure/high-temperature Barrovian type of metamorphism, developing a sequence of metamorphic zones (biotite, garnet, staurolite ...
