Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats
The Anatomical Record, EarlyView.Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

ESG Controversies in Global Firms: A Black Mark?
Business Strategy and the Environment, EarlyView.ABSTRACT Despite increasing attention paid by companies to sustainability, there is still evidence of environmental, social and governance (commonly referred to as ESG) scandals. As research on this topic is scant, this paper aims to analyse the impact of ESG controversies on firms' sustainability practices, that is, ESG policies, as well as ...

, 2015 In this work, we focus on class of timelike rotational surfaces in Minkowski space E_1^4 with 2-dimensional axis. There are three types of rotational surfaces with 2-dimensional axis, called rotational surfaces of elliptic, hyperbolic and parabolic type.

Gauss map of minimal surfaces with ramification [PDF]
Transactions of the American Mathematical Society, 1993 We prove that for any complete minimal surface M M immersed in R n {R^n} , if in C P n − 1 C{P^{n - 1}} there are q > n

The Canadian Journal of Chemical Engineering, EarlyView.Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

Experimental methods in chemical engineering: Magnetometry
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

On the Gauss map of a class of hypersurfaces in ℍ4
AIP Conference Proceedings, 2018 We consider hypersurfaces of Riemannian space forms in terms of the type of their Gauss map, spherical Gauss mapor hyperbolic Gauss map. We give a brief summary of results on submanifolds withLkfinite type Gauss map fork>0. We alsoobtain some classification results.

Nonlinear permuted Granger causality
Canadian Journal of Statistics, EarlyView.Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

Convex Combinations of Minimal Graphs
International Journal of Mathematics and Mathematical Sciences, 2012 Given a collection of minimal graphs, 𝑀1,𝑀2,…,𝑀𝑛, with isothermal parametrizations in terms of the Gauss map and height differential, we give sufficient conditions on 𝑀1,𝑀2,…,𝑀𝑛 so that a convex combination of them will be a minimal graph.
