Does long-term memory affect refreshing in verbal working memory?

Camos, Valerie ; Mora, Gérôme ; Oftinger, Anne-Laure ; Mariz Elsig, Stéphanie ; Schneider, Philippe ; Vergauwe, Evie

In: Journal of Experimental Psychology: Learning, Memory and Cognition, 2019, vol. 45, no. 9, p. 1664-1682

Attentional refreshing allows the maintenance of information in working memory and has received growing interest in recent years. However, it is still ill-defined and several proposals have been put forward to account for its functioning. Among them, some proposals suggest that refreshing relies on the retrieval of knowledge from semantic long-term memory. To examine such a proposal, the present...

Partitioning the uncertainty of ensemble projections of global glacier mass change

Marzeion, Ben ; Hock, Regine ; Anderson, Brian ; Bliss, Andrew ; Champollion, Nicolas ; Fujita, Koji ; Huss, Matthias ; Immerzeel, Walter W. ; Kraaijenbrink, Philip ; Malles, Jan‐Hendrik ; Maussion, Fabien ; Radić, Valentina ; Rounce, David R. ; Sakai, Akiko ; Shannon, Sarah ; Wal, Roderik ; Zekollari, Harry

Glacier mass loss is recognized as a major contributor to current sea level rise. However, large uncertainties remain in projections of glacier mass loss on global and regional scales. We present an ensemble of 288 glacier mass and area change projections for the 21st century based on 11 glacier models using up to 10 general circulation models and four Representative Concentration Pathways...

A revision of Ophidiaster davidsoni de Loriol and Pellat 1874 from the Tithonian of Boulogne (France) and its transfer from the Valvatacea to the new forcipulatacean genus Psammaster gen. nov.

Fau, Marine ; Villier, Loïc ; Ewin, Timothy A. M. ; Gale, Andrew S.

In: Fossil Record, 2020, vol. 23, no. 2, p. 141–149

Forcipulatacea is one of the three major groups of extant sea stars (Asteroidea: Echinodermata), composed of 400 extant species, but only known from fewer than 25 fossil species. Despite unequivocal members being recognized in the early Jurassic, the evolutionary history of this group is still the subject of debate. Thus, the identification of any new fossil representatives is significant. We...

New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of early Rhinocerotidae (Perissodactyla)

Tissier, Jérémy ; Antoine, Pierre-Olivier ; Becker, Damien

In: Royal Society Open Science, 2020, vol. 7, no. 7, p. 200633

Reduction of the anterior dentition (i.e. incisors and canines) is a major adaptative trait of the Rhinocerotidae among Perissodactyla. However, the corresponding evolutionary sequence was lacking a robust phylogenetic frame to support it thus far. Here, we describe a new Oligocene species of Rhinocerotinae, Mesaceratherium sp. nov. from the Swiss locality of Bumbach (MP25 reference level)....

Electronic structure beyond the generalized gradient approximation for ${\mathrm{Ni}}_{2}\mathrm{MnGa}$

Baigutlin, D. R. ; Sokolovskiy, V. V. ; Miroshkina, O. N. ; Zagrebin, M. A. ; Nokelainen, J. ; Pulkkinen, Aki ; Barbiellini, B. ; Pussi, K. ; Lähderanta, E. ; Buchelnikov, V. D. ; Zayak, A. T.

In: Physical Review B, 2020, vol. 102, no. 4, p. 045127

The stability of the nonmodulated martensitic phase, the austenitic Fermi surface, and the phonon dispersion relations for ferromagnetic Ni2MnGa are studied using density functional theory. Exchange-correlation effects are considered with various degrees of precision, starting from the simplest local spin density approximation (LSDA), then adding corrections within the generalized gradient...

Ab initio description of the ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+{\delta}}$ electronic structure

Nokelainen, Johannes ; Lane, Christopher ; Markiewicz, Robert S. ; Barbiellini, Bernardo ; Pulkkinen, Aki ; Singh, Bahadur ; Sun, Jianwei ; Pussi, Katariina ; Bansil, Arun

In: Physical Review B, 2020, vol. 101, no. 21, p. 214523

Bi-based cuprate superconductors are important materials for both fundamental research and applications. As in other cuprates, the superconducting phase in the Bi compounds lies close to an antiferromagnetic phase. Our density functional theory calculations based on the strongly-constrained-and- appropriately-normed exchange correlation functional in ...

Overcommuting pairs in groups and 3-manifolds bounding them

Liechti, Livio ; Marché, Julien

In: Journal of the London Mathematical Society, 2020, p. -

We introduce the notions of overcommutation and overcommutation length in groups, and show that these concepts are closely related to representations of the fundamental groups of 3-manifolds and their Heegaard genus. We give many examples including translations in the affine group of the line and provide upper bounds for the overcommutation length in SL2, related to the Steinberg relation.

Fish, amphibian and reptilian assemblage from the middle Miocene locality Gračanica—Bugojno palaeolake, Bosnia and Herzegovina

Vasilyan, Davit

In: Palaeobiodiversity and Palaeoenvironments, 2020, vol. 100, no. 2, p. 437–455

This paper presents the first fossil fish, amphibian and reptilian fauna from Bosnia and Herzegovina Dinarides. The fauna of ectothermic vertebrates of the Bugojno palaeolake, dated to 15.2–14.0 Ma, composes of killifishes (Cyprinodontiformes indet.), a barb (Barbini indet. (aff. Barbus), a crocodile newt (Chelotriton sp.), a painted frog (Latonia sp.) and a crocodile (Alligatoroidea indet....
