A Selective Advantage for Conservative Viruses [PDF]

open access: yes, 2004
In this letter we study the full semi-conservative treatment of a model for the co-evolution of a virus and an adaptive immune system. Regions of viability are calculated for both conservatively and semi-conservatively replicating viruses interacting with a realistic semi-conservatively replicating immune system. The conservative virus is found to have

Non-conservation and conservation for different formulations of moist potential vorticity [PDF]

open access: yesarXiv, 2023
Potential vorticity (PV) is one of the most important quantities in atmospheric science. The PV of each fluid parcel is known to be conserved in the case of a dry atmosphere. However, a parcel's PV is not conserved if clouds or phase changes of water occur.

The archaeological laboratory as an interdisciplinary meeting point: the experience of the Facoltà di Conservazione dei Beni Culturali

open access: yesConservation Science in Cultural Heritage, 2002
The opening of archaeological laboratory in the “Dipartimento di Storie e Metodi per la Conservazione dei Beni Culturali“ means an important stage in the way of Phoenician and Punic studies.

Non-conservation of Carter in black hole spacetimes [PDF]

open access: yes, 2015
Freely falling point particles in the vicinity of Kerr black holes are subject to a conservation law, that of their Carter constant. We consider the conjecture that this conservation law is a special case of a more general conservation law, valid for arbitrary processes obeying local energy momentum conservation.

Area-based conservation in the twenty-first century

open access: yesNature, 2020
Humanity will soon define a new era for nature—one that seeks to transform decades of underwhelming responses to the global biodiversity crisis.

Nuclear techniques for the analysis and dating of cultural heritage with the tandetron accelerator at the CEDAD

open access: yesConservation Science in Cultural Heritage, 2014
The Accelerator Mass Spectrometry technique for measuring carbon isotopes and dating artifacts, together with nuclear techniques of ion beam analysis are widely used in the field of cultural heritage owing to the great advantage of their being non ...

Symmetries and scaling in generalised coupled conserved Kardar-Parisi-Zhang equations [PDF]

open access: yes, 2017
We study the noisy nonequilibrium dynamics of a conserved density that is driven by a fluctuating surface governed by the conserved Kardar-Parisi-Zhang equation. We uncover the universal scaling properties of the conserved density. We consider two separate minimal models where the surface fluctuations couple (i) with the spatial variation of the ...

Effects of chronic browsing on life‐history traits of an irruptive large herbivore population

open access: yesPopulation Ecology, EarlyView.
This study aimed to determine the relationship between diet quality, body mass, and size (hind foot length), and female reproduction and sought to identify the mechanism by which high density under severe food limitations is maintained. Our results demonstrated that sika deer introduced to Nakanoshima Island have maintained high densities through high ...

Tursi: the Rabatana

open access: yesConservation Science in Cultural Heritage, 2004
There are many important factors which make the town of Tursi an exceptional case in the pattern of human settlements in Basilicata: to begin with, it was the Capital of Leukanía, the third Byzantine thema of the Catepanate of Italy; then, it acquired a ...
