It Takes Two : Instrumenting the Interaction between In-Memory Databases and Solid-State Drives

Lerner, Alberto ; Kwak, Jaewook ; Lee, Sangjin ; Park, Kibin ; Song, Yong Ho ; Cudré-Mauroux, Philippe

In: CIDR 2020, 10th Conference on Innovative Data Systems Research, Amsterdam, The Netherlands, January 12-15, 2020, Online Proceedings, 2020, p. 1-8

In-memory databases rely on non-volatile storage devices for services such as durability and recovery. SSDs can provide the high-performance these services require. When performance problems occur, however, SSDs offer no mechanism to help analyze them. The only alternative is to instrument the database side of the problem and conjecture about what might be the cause of performance...

Neuroanatomy of the spinosaurid Irritator challengeri (Dinosauria: Theropoda) indicates potential adaptations for piscivory

Schade, Marco ; Rauhut, Oliver W. M. ; Evers, Serjoscha W.

In: Scientific Reports, 2020, vol. 10, no. 1, p. 9259

Spinosauridae, a theropod group characterized by elongated snouts, conical teeth, enlarged forelimbs, and often elongated neural spines, show evidence for semiaquatic adaptations and piscivory. It is currently debated if these animals represent terrestrial carnivores with adaptations for a piscivorous diet, or if they largely lived and foraged in aquatic habitats. The holotype of Irritator...

A new species of baenid turtle from the Early Cretaceous Lakota Formation of South Dakota

Joyce, Walter G. ; Rollot, Yann ; Cifelli, Richard L.

In: Fossil Record, 2020, vol. 23, no. 1, p. 1–13

Baenidae is a clade of paracryptodiran turtles known from the late Early Cretaceous to Eocene of North America. The proposed sister-group relationship of Baenidae to Pleurosternidae, a group of turtles known from sediments dated as early as the Late Jurassic, suggests a ghost lineage that crosses the early Early Cretaceous. We here document a new species of paracryptodiran turtle, Lakotemys...

A new trackway possibly made by a trotting theropod at the Las Hoyas fossil site (Early Cretaceous, Cuenca Province, Spain): Identification, bio-dynamics and palaeoenvironmental implications

Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs

Foth, Christian ; Rauhut, Oliver W. M.

In: BMC Evolutionary Biology, 2017, vol. 17, p. 236

Archaeopteryx is an iconic fossil that has long been pivotal for our understanding of the origin of birds. Remains of this important taxon have only been found in the Late Jurassic lithographic limestones of Bavaria, Germany. Twelve skeletal specimens are reported so far. Archaeopteryx was long the only pre-Cretaceous paravian theropod known, but recent discoveries from the Tiaojishan...

Recherches et réflexions inhérentes à la conception d'un support pour des prélèvements de couches géologiques : en vue de leur étude et de leur exposition

Miserez, Claudine

Mémoire de bachelor : Haute Ecole Arc Conservation-Restauration, 2012.

During excavations on the construction site of the A16 motorway which crosses the county of Jura (Switzerland), many paleontological sites have been unearthed by the Section d’Archéologie et Paléontologie (SAP) of the County Office for Culture (Office Cantonal de la Culture). Six of these sites have yielded tracks of dinosaurs, embedded into the soil 152 million years ago by various sauropods...
