Question: which character did Jacob Brent play who is also sometimes called Quaxo?

Context paragraphs:
Laplace distribution: In probability theory and statistics, the Laplace distribution is a continuous probability distribution named after Pierre-Simon Laplace.  It is also sometimes called the "double exponential distribution", because it can be thought of as two exponential distributions (with an additional location parameter) spliced together back-to-back, although the term 'double exponential distribution' is also sometimes used to refer to the Gumbel distribution.  The difference between two independent identically distributed exponential random variables is governed by a Laplace distribution, as is a Brownian motion evaluated at an exponentially distributed random time.  Increments of Laplace motion or a variance gamma process evaluated over the time scale also have a Laplace distribution.

Mr. Mistoffelees: Mr. Mistoffelees is a character in T. S. Eliot's poetry book "Old Possum's Book of Practical Cats" and its stage adaptation, Andrew Lloyd Webber's popular musical "Cats".  He is an important primary character, and one of the most popular of the show.  He is also sometimes named Quaxo.

Peristimulus time histogram: In neurophysiology, peristimulus time histogram and poststimulus time histogram, both abbreviated PSTH or PST histogram, are histograms of the times at which neurons fire.  It is also sometimes called pre event time histogram or PETH.  These histograms are used to visualize the rate and timing of neuronal spike discharges in relation to an external stimulus or event.  The peristimulus time histogram is sometimes called perievent time histogram, and "post-stimulus" and "peri-stimulus" are often hyphenated.

Ring-tailed cat: The ringtail ("Bassariscus astutus") is a mammal of the raccoon family, native to arid regions of North America.  It is also known as the ringtail cat, ring-tailed cat, miner's cat or bassarisk, and is also sometimes called a "civet cat" (after similar, though unrelated, cat-like omnivores of Asia and Africa).  The ringtail is sometimes called a cacomistle, though this term seems to be more often used to refer to "Bassariscus sumichrasti".

Coracoid tubercle: The coracoid tubercle is an anatomical feature of the pectoral skeleton in archosaurs, including maniraptoran dinosaurs.  It is sometimes called the biceps tubercle.  It is also sometimes called the coracoid tuber or biceps tuber.

Jacob Brent: Jacob 'Jazzy' Brent (born August 14, 1973) is an American stage actor who is most famous for his role as the Magical Mr. Mistoffelees in the video production of CATS which was filmed in 1998.  He graduated from the North Carolina School of the Arts in 1991.  Jacob also worked with the ALICE workshop, a musical based on Alice in Wonderland as well as his own showcase at the Sadlers Wells Theatre.  In 2002, he worked with choreography during the Elan Awards and the Dance with Dancers Millennium Gala for the New York City Ballet.  Jacob now donates his time and talent to San Jose Children's Musical Theatre, where he is directing their 2008 production of "Peter Pan" as well as their 2009 Spring Production of Leonard Bernstein's "Candide".  He holds a Masters of Fine Arts from San Diego State University.  In 2016, Brent was appointed Assistant Professor of Dance at Shenandoah University.  There, he instructs students in the art of becoming "Jazz Warriors".

R-factor (crystallography): In crystallography, the R-factor (sometimes called residual factor or reliability factor or the R-value or R) is a measure of the agreement between the crystallographic model and the experimental X-ray diffraction data.  In other words, it is a measure of how well the refined structure predicts the observed data.  The value is also sometimes called the discrepancy index, as it mathematically describes the difference between the experimental observations and the ideal calculated values.  It is defined by the following equation:

Ideal triangle: In hyperbolic geometry an ideal triangle is a hyperbolic triangle whose three vertices all are ideal points. Ideal triangles are also sometimes called "triply asymptotic triangles" or "trebly asymptotic triangles".  The vertices are sometimes called ideal vertices.  All ideal triangles are congruent.

Jacques Lefèvre d'Étaples: Jacques Lefèvre d'Étaples or Jacobus Faber Stapulensis (c. 1455 – 1536) was a French theologian and humanist.  He was a precursor of the Protestant movement in France.  The "d'Étaples" was not part of his name as such, but used to distinguish him from Jacques Lefèvre of Deventer, a less significant contemporary, a friend and correspondent of Erasmus.  Both are also sometimes called by the German version of their name, Jacob/Jakob Faber.  He himself had a sometimes tense relationship with Erasmus, whose work on Biblical translation and in theology closely paralleled his own.

Chateau Bay: Chateau Bay (sometimes called Chateaux Bay) is a settlement and bay in Labrador, Canada.  Historically it is also sometimes called York Harbour, a name given by James Webb in 1760 when he claimed the harbour for the English.  It was surveyed by James Cook in 1763, during his survey of the Strait of Belle Isle aboard HMS "Grenville".  In August 1766 Joseph Banks arrived in Chateau Bay as a part of a partially scientific journey to study and collect the plants and animals.  One of the specimens collected there was the now extinct great auk.
