Reentrant condensation transition in a two species driven diffusive system [PDF]

open access: yesPhysica A 477, 1-8 (2017), 2016
We study an interacting box-particle system on a one-dimensional periodic ring involving two species of particles $A$ and $B$. In this model, from a randomly chosen site, a particle of species $A$ can hop to its right neighbor with a rate that depends on the number of particles of the species $B$ at that site. On the other hand, particles of species $B$

Genome size variation and polyploidy prevalence in the genus Eragrostis are associated with the global dispersal in arid area

open access: yesFrontiers in Plant Science, 2023
BackgroundBiologists have long debated the drivers of the genome size evolution and variation ever since Darwin. Assumptions for the adaptive or maladaptive consequences of the associations between genome sizes and environmental factors have been ...

From terra incognita to hotspot: the largest South Pacific green turtle nesting population in the forgotten reefs of New Caledonia

open access: yesOryx, 2023
The green turtle Chelonia mydas is a large marine turtle present in tropical and subtropical seas of the Atlantic, Pacific and Indian Oceans. It is categorized as Endangered on the IUCN Red List based on the trend of nesting populations at 32 sites, of ...

Birds of a Feather: Capturing Avian Shape Models from Images [PDF]

open access: yesarXiv, 2021
Animals are diverse in shape, but building a deformable shape model for a new species is not always possible due to the lack of 3D data. We present a method to capture new species using an articulated template and images of that species. In this work, we focus mainly on birds.

The Role of Vessel Biofouling in the Translocation of Marine Pathogens: Management Considerations and Challenges

open access: yesFrontiers in Marine Science, 2021
Vessel biofouling is a major pathway for the introduction, establishment, and subsequent spread of marine non-indigenous macro-organisms. As a result, national and international regulations and guidelines have been implemented to manage the risks ...

Asymmetric Fermion Superfluid with Inter- and Intra-Species Pairings [PDF]

open access: yesNew J. Phys.9 (2007) 375, 2006
We investigate the phase structure of an asymmetric fermion superfluid with inter- and intra-species pairings. The introduction of the intra-species pairing mechanism in canonical ensemble changes significantly the phase diagram and brings in a new state with coexisting inter- and intra-species pairings.

NEW SPECIES OF CYNIPIDAE [PDF]

open access: yesThe Canadian Entomologist, 1881
Cynips (Q. Californica, n. sp.Galls: Polythalamous, sessile on the branches of the Californian White Oak (Quercus Hindsii ?) Sub-globular, but varying much in form and size. A common form is what may be termed balloon-shaped, the upper part perfectly globular, the lower tapering more or less to the sessile base.
