A refined propensity account for GRW theory

Lorenzetti, Lorenzo

In: Foundations of Physics, 2021, vol. 51, no. 2, p. 20

Spontaneous collapse theories of quantum mechanics turn the usual Schrödinger equation into a stochastic dynamical law. In particular, in this paper I will focus on the GRW theory. Two philosophical issues that can be raised about GRW concern (a) the ontology of the theory, in particular the nature of the wave function and its role within the theory, and (b) the interpretation of the objective...

Liquidity analysis in the LNG market, illustrating the stakes to become a mature commodity market

Millet, Ludovic ; Piller, Robert (Dir.)

Mémoire de bachelor : Haute école de gestion de Genève, 2020 ; TDIBM 89.

With the environmental considerations being at the heart of the decade, and the energy industry being regarded as a negative contributor, more environmentally friendly ways to power generation are being studied. However, fossil energies are still a major contributor to power generation, and greener substitutes face a hard time to be commercialised at big scale. Natural gas, a fossil energy...

Dental anomaly in a middle Miocene fossil of the genus Spermophilinus (Rodentia, Sciuridae) from southern Germany

Prieto, Jérôme ; Rummel, Michael ; Peláez-Campomanes, Pablo ; Vasilyan, Davit

In: Fossil Imprint, 2020, vol. 76, no. 1, p. 174-180

The maxillary presented in this work has been excavated in the middle Miocene karst filling Petersbuch 136 (Germany, Bavaria) and shows the oldest evidence of dental anomaly in a sciurid. The aberrant morphology, probably hyperdontia or no replacement of roots of deciduous teeth, affects the area of the P3, a tooth that is generally not well documented in the Spermophilinus record.

First fossil frog from Antarctica: implications for Eocene high latitude climate conditions and Gondwanan cosmopolitanism of Australobatrachia

Mörs, Thomas ; Reguero, Marcelo ; Vasilyan, Davit

In: Scientific Reports, 2020, vol. 10, p. 5051

Cenozoic ectothermic continental tetrapods (amphibians and reptiles) have not been documented previously from Antarctica, in contrast to all other continents. Here we report a fossil ilium and an ornamented skull bone that can be attributed to the Recent, South American, anuran family Calyptocephalellidae or helmeted frogs, representing the first modern amphibian found in Antarctica. The two bone...

The fossil record of the genus Varanus from the Southern Caucasus (Armenia, Georgia)

Vasilyan, Davit ; Bukhsianidze, Maia

In: PeerJ, 2020, p. e8322

The Southern Caucasus, with its special geographic position and complex topography, is a well-known biodiversity hotspot. However, the formation of this hotspot remains largely unstudied. To reveal this, a thorough study of the fossil record of the region is necessary. In the present paper, we describe for the first time fossil monitor lizards (Varanus sp.) from two late Miocene localities from...

Understanding of object rotation between two and three years of age

Pedrett, Salome ; Kaspar, Lea ; Frick, Andrea

In: Developmental Psychology, 2020, vol. 56, p. 261-274

Toddlers’ understanding of object rotation was investigated using a multi-method approach. Participants were 44 toddlers between 22 and 38 months of age. In an eye-tracking task, they observed a shape that rotated and disappeared briefly behind an occluder. In an object-fitting task, they rotated wooden blocks and fit them through apertures. Results of the eye-tracking task showed that with...
