The return to the Iberian Peninsula: first Quaternary record of Muscardinus and a palaeogeographical overview of the genus in Europe
(Elsevier, 2015-05-18)
Although the earliest record of the genus Muscardinus dates from the Middle Miocene in Spain, no mention has been reported since the Lower Pliocene in the Iberian Peninsula. In this paper, Quaternary fossil remains of a ...
Bending rigidity, sound propagation and ripples in flat graphene
(Springer Nature, 2024-05-16)
Many of the applications of graphene rely on its uneven stiffness and high thermal conductivity, but the mechanical properties of graphene—and, in general, of all two-dimensional materials—are still not fully understood. ...
Cohomology of p-groups of nilpotency class smaller than p
(De Gruyter, 2018-01-17)
Let p be a prime number, let d be an integer and let G be a d-generated finite p-group of nilpotency class smaller than p. Then the number of possible isomorphism types for the mod p cohomology algebra H^∗(G;F_p) is bounded ...
Genetic turnovers and northern survival during the last glacial maximum in European brown bears
(John Wiley & Sons, 2019-05-29)
The current phylogeographic pattern of European brown bears (Ursus arctos) has
commonly been explained by postglacial recolonization out of geographically distinct
refugia in southern Europe, a pattern well in accordance ...
Isothermal oxidation kinetics of nitrided Ti-6Al-4V studied by infrared emissivity
(Elsevier, 2020-08-15)
The oxidation kinetics of Ti-6Al-4V samples nitrided in forming gas (N2+5%H2) between 520 and 805 °C is investigated using infrared emissivity measurements. Several kinetic exponents have been observed depending on temperature ...
Application of parabolic cracks in determining handedness in archaeological remains. The case study of the Axlor site (Bizkaia, Iberian Peninsula)
(Elsevier, 2022-06)
[EN] Lithic artefacts are a potential source of information for the study of handedness in different human species. In flint flakes, a system of fractures is developed (parabolic cracks) around the point of percussion in ...
Quartzite procurement in conglomerates and deposits:Geoarchaeological characterization of potential catchmentareas in the central part of the Cantabrian Region, Spain
(Wiley, 2021-05)
Raw material characterization in Paleolithic archaeology has widened our knowledge of Middle Paleolithic societies. Procurement of raw material, specifically flint, has allowed the tracing of the mobility of both stones ...
Using Mg/Ca Ratios from the Limpet Patella depressa Pennant, 1777 Measured by Laser-Induced Breakdown Spectroscopy (LIBS) to Reconstruct Paleoclimate
(MDPI, 2021-03-25)
Measurement of the elemental composition of shells is increasingly emerging as an avenue for obtaining high-resolution insights into paleoclimate and past seasonality. Several studies have shown significant correlations ...
Spatial interpretation of high-resolution environmental proxy data of the Middle Pleistocene Palaeolithic faunal kill site Schöningen 13 II-4, Germany 13 II-4, Germany
(Wiley, 2023-06-07)
To spatially characterize the palaeolakeshore environment at the archaeological kill site Sch€oningen 13 II-4 of the
Middle Pleistocene Reinsdorf sequence, in-depth palynological, geochemical, aquatic microfossil and ...
Middle Pleistocene protein sequences from the rhinoceros genus Stephanorhinus and the phylogeny of extant and extinct Middle/Late Pleistocene Rhinocerotidae
(PeerJ Inc., 2017-03-14)
Ancient protein sequences are increasingly used to elucidate the
phylogenetic relationships between extinct and extant mammalian taxa. Here, we
apply these recent developments to Middle Pleistocene bone specimens of ...
