#### Numerical solution of nonlinear matrix equations arising from Green's function calculations in nano research

(Elsevier, 2012)

The Green's function approach for treating quantum transport in nano devices requires the solution of nonlinear matrix equations of the form
$X+(C^*+{\rm i} \eta D^*)X^{-1}(C+{\rm i} \eta D)=R+{\rm i}\eta P$, where $R$ ...

#### On Newton's method and Halley's method for the principal $p$th root of a matrix

(Elsevier, 2010)

If $A$ is a matrix with no negative real eigenvalues
and all zero eigenvalues of $A$ are semisimple, the principal
$p$th root of $A$ can be computed by Newton's method or Halley's method,
with a preprocessing procedure ...

#### Convergence rates of some iterative methods for nonsymmetric algebraic Riccati equations arising in transport theory

(Elsevier, 2010)

We determine and compare the convergence rates of various
fixed-point iterations for finding the minimal positive solution of
a class of nonsymmetric algebraic
Riccati equations arising
in transport theory.

#### The principal rank characteristic sequence over various fields

(Elsevier, 2014)

Given an n-by-n matrix, its principal rank characteristic sequence is a sequence of
length n + 1 of 0s and 1s where, for k = 0; 1,..., n, a 1 in the kth position indicates
the existence of a principal submatrix of rank ...

#### Operationalizing Ethics in Food Choice Decisions

(Springer, 2014-06)

There is a large gap between attitude and action when it comes to consumer purchases of ethical food. Amongst the various aspects of this gap, this paper focuses on the difficulty in knowing enough about the various ...

#### Approximation and Visualization of Sets Defined by Iterated Function Systems

(University of Regina, 1991-03)

An iterated function system (IFS) is defined to be a set of contractive affine transformations. When iterated, these transformations define a closed set, called the attractor of an IFS, which has fractal characteristics. ...

#### Home is where you hang your bat: winter roost selection by prairie-living big brown bats

(American Society of Mammalogists, 2017)

Information on the roost requirements of small, temperate-zone hibernating bats, which can spend up to 8 months
in hibernation, is crucial to their conservation. We studied male big brown bats (Eptesicus fuscus) in ...

#### Stressful summers? Torpor expression differs between high- and low-latitude populations of bats

(American Society of Mammalogists, 2017)

Variation in weather and food availability impacts the energy budgets of endotherms, with some species using
torpor as an energy-saving strategy during periods of negative energy balance. We evaluated how latitudinal
differences ...

#### Hung out to dry? Intraspecific variation in water loss in a hibernating bat

(Springer, 2017)

Hibernation is a period of water deficit for some
small mammals, and humidity strongly influences hibernation
patterns. Dry conditions reduce length of torpor bouts,
stimulate arousals, and decrease overwinter survival. ...
