Genome Sequence of Aeribacillus pallidus Strain GS3372, an Endospore-Forming Bacterium Isolated in a Deep Geothermal Reservoir

Filippidou, Sevasti ; Jaussi, Marion ; Junier, Thomas ; Wunderlin, Tina ; Jeanneret, Nicole ; Regenspurg, Simona ; Li, Po-E ; Lo, Chien-Chi ; Johnson, Shannon ; McMurry, Kim ; Gleasner, Cheryl D ; Vuyisich, Momchilo ; Chain, Patrick S ; Junier, Pilar

In: Genome Announcements, 2015, vol. 3, no. 4, p. e00981-15

The genome of strain GS3372 is the first publicly available strain of Aeribacillus pallidus. This endospore-forming thermophilic strain was isolated from a deep geothermal reservoir. The availability of this genome can contribute to the clarification of the taxonomy of the closely related Anoxybacillus, Geobacillus, and Aeribacillus genera.

A review of the fossil record of nonbaenid turtles of the clade Paracryptodira

Joyce, Walter G. ; Anquetin, Jérémy

In: Bulletin of the Peabody Museum of Natural History, 2019, vol. 60, no. 2, p. 129–155

The fossil record of nonbaenid paracryptodires ranges from the Late Jurassic (Kimmeridgian) to the Paleocene of North America and Europe only. Earlier remains may be present as early as the Middle Jurassic (Bathonian). Only a single dispersal event is documented between the two continents after their breakup during the Cretaceous in the form of the appearance of the Compsemys lineage in the ...

Estimating the phylogeny of geoemydid turtles (Cryptodira) from landmark data: an assessment of different methods

Ascarrunz​, Eduardo ; Claude, Julien ; Joyce, Walter G.

In: PeerJ, 2019, vol. 7, p. e7476

Background: In the last 20 years, a general picture of the evolutionary relationships between geoemydid turtles (ca. 70 species distributed over the Northern hemisphere) has emerged from the analysis of molecular data. However, there is a paucity of good traditional morphological characters that correlate with the phylogeny, which are essential for the robust integration of fossil and...

Serial electron microscopic reconstruction of the drosophila larval eye: Photoreceptors with a rudimentary rhabdomere of microvillar-like processes

Hartenstein, Volker ; Yuan, Michaela ; Younossi-Hartenstein, Amelia ; Karandikar, Aanavi ; Bernardo-Garcia, F. Javier ; Sprecher, Simon G. ; Knust, Elisabeth

In: Developmental Biology, 2019, vol. 453, no. 1, p. 56–67

Photoreceptor cells (PRCs) across the animal kingdom are characterized by a stacking of apical membranes to accommodate the high abundance of photopigment. In arthropods and many other invertebrate phyla PRC membrane stacks adopt the shape of densely packed microvilli that form a structure called rhabdomere. PRCs and surrounding accessory cells, including pigment cells and lens-forming cells,...

La forme des interrogatives dans le Corpus suisse de SMS en français : étude multidimensionnelle

Guryev, Alexander ; Béguelin, Marie-José (Dir.) ; Lefeuvre, Florence (Codir.) ; Coveney, Aidan (Codir.) ; Le Goffic, Pierre (Codir.) ; Stark, Elisabeth (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2017.

La présente thèse s’inscrit dans le projet FNS Sinergia 136230 “SMS communication in Switzerland: Facets of Linguistic Variation in a Multilingual Country”. Ella a pour but d’étudier la variabilité formelle des questions dans le Corpus suisse de SMS en français, en montrant comment l’analyse des données en provenance des interactions informelles autres que l’oral spontané –...

Towards the democratization of ontological modeling through a new pervasive means of representation

Baset, Selena ; Stoffel, Kilian (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019 ; 2787.

Despite their proven utility in various areas of knowledge engineering, ontologies are falling short of reaching an equal position as formal domain models in the landscape of enterprise software development. With the ultimate goal of making ontologies more accessible to a wider audience of software development stakeholders, this thesis investigates the reasons that are still standing between...

Under-detection of endospore-forming Firmicutes in metagenomic data

Filippidou, Sevasti ; Junier, Thomas ; Wunderlin, Tina ; Lo, Chien-Chi ; Li, Po-E ; Chain, Patrick S ; Junier, Pilar

In: Computational and Structural Biotechnology Journal, 2015, vol. 13, p. 299-206

Microbial diversity studies based on metagenomic sequencing have greatly enhanced our knowledge of the microbial world. However, one caveat is the fact that not all microorganisms are equally well detected, questioning the universality of this approach. Firmicutes are known to be a dominant bacterial group. Several Firmicutes species are endospore formers and this property makes...

Quench dynamics and Hall response of interacting Chern insulators

Schüler, Michael ; Budich, Jan Carl ; Werner, Philipp

In: Physical Review B, 2019, vol. 100, no. 4, p. 041101

We study the coherent nonequilibrium dynamics of interacting two-dimensional systems after a quench from a trivial to a topological Chern insulator phase. While the many-body wave function is constrained to remain topologically trivial under local unitary evolution, we find that the Hall response of the system can dynamically approach a thermal value of the postquench Hamiltonian, even though...

The C-terminal domain of TPX2 is made of alpha-helical tandem repeats

Sanchez-Pulido, Luis ; Perez, Laurent ; Kuhn, Steffen ; Vernos, Isabelle ; Andrade-Navarro, Miguel A.

In: BMC structural biology, 2016, vol. 16, p. 17

Background: TPX2 (Targeting Protein for Xklp2) is essential for spindle assembly, activation of the mitotic kinase Aurora A and for triggering microtubule nucleation. Homologs of TPX2 in Chordata and plants were previously identified. Currently, proteins of the TPX2 family have little structural information and only small parts are covered by defined protein domains. Methods: We have used ...
