Confidence intervals for extinction risk: Validating population viability analysis with limited data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract The assessment of extinction risk remains a key component of IUCN and CITES evaluations. However, it has been argued that, under realistic data limitations, confidence intervals (CIs) for extinction probability often span the entire 0–1 range, rendering such assessments meaningless.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

open access: yesComputer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

Computation of hydromagnetic tangent hyperbolic non-Newtonian flow from a rotating non-isothermal cone to a non-Darcy porous medium with thermal radiative flux

open access: yesPhysics Open
A theoretical and numerical study is conducted on nonlinear, steady-state thermal convection boundary layer flow of a magnetized incompressible Tangent Hyperbolic non-Newtonian fluid from a rotating cone to a non-Darcy porous medium.

The Legacy of Policy Inaction in Climate‐Growth Models

open access: yesInternational Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

The Cost of Convenience: A Hedonic Approach to Travel Time Valuation and Cost‐Benefit Analysis

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT This paper presents a novel revealed‐preference approach to estimating the value of travel time (VTT) and calculating consumer surplus for the economic evaluation of transport infrastructure. Departing from traditional stated‐preference models, we derive time valuations by linking residential rental transactions in Greater Sydney to employment

PERISTALTIC PUMPING OF A HYPERBOLIC TANGENT FLUID THROUGH A PERMEABLE CHANNEL WITH SUCTION/INJECTION

open access: yes, 2019
The flow of peristaltic hyperbolic tangential fluid past porous walls with suction/injection is investigated. The regular perturbation method has been implemented to establish the appropriate expressions for velocity and pressure rise per wavelength by means of the assumptions of long wavelength and low valued Renolds number.
