Real Scalar Field Scattering with Polynomial Approximation around Schwarzschild-de Sitter Black-hole

, 2008
As one of the fitting methods, the polynomial approximation is effective to process sophisticated problem. In this paper, we employ this approach to handle the scattering of scalar field around the Schwarzschild-de Sitter black-hole.

Population genomics through time provides insights into the consequences of decline and rapid demographic recovery through head‐starting in a Galapagos giant tortoise

Evolutionary Applications, 2018
Population genetic theory related to the consequences of rapid population decline is well‐developed, but there are very few empirical studies where sampling was conducted before and after a known bottleneck event.

Giant Tortoise Coordinate [PDF]

, 2018
We propose a new null shell collapse scenario based on an asymptotically drifting moving mirror. The resulting black hole is described in a generalization of the usual tortoise coordinate system, which we refer to as the “giant tortoise coordinate”.

Social information about others' affective states in a human‐altered world

Journal of Animal Ecology, EarlyView.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Genomic and Functional Characterization of CTX-M-15-Producing Klebsiella pneumoniae ST307 Isolated from Imported Leopard Tortoises in Germany

Applied Microbiology
The Klebsiella pneumoniae ST307 clone, identified in the mid-1990s, has emerged as a global antimicrobial-resistant (AMR) high-risk clone, significantly contributing to the global health challenge also posed by other AMR K. pneumoniae lineages.

The illegal pet trade is driving Madagascar's ploughshare tortoise to extinction

Oryx, 2018
The illegal wildlife trade is driving declines in populations of a number of large, charismatic animal species but also many lesser known and restricted-range species, some of which are now facing extinction as a result.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Multiple Organ Dysfunction Syndrome (MODS) induced by Candida krusei in an Aldabra giant tortoise (Aldabrachelys gigantea) and confirmed by electron microscopy analysis

Medical Mycology Case Reports, 2018
A young female Aldabra giant tortoise (Adabrachelys gigantea) was presented with anorexia, ataxia, severe constipation and bloating. Analysis revealed liver disease and collected biopsy diagnosed Candida krusei infection.

Hawking Radiation of Dirac Particles in a Variable-mass Kerr Space-time [PDF]

, 2001
Hawking effect of Dirac particles in a variable-mass Kerr space-time is investigated by using a method called as the generalized tortoise coordinate transformation.
