Controls on gut phosphatisation : the trilobites from the Weeks Formation Lagerstätte (Cambrian; Utah) [PDF]

, 2012
Despite being internal organs, digestive structures are frequently preserved in Cambrian Lagerstätten. However, the reasons for their fossilisation and their biological implications remain to be thoroughly explored.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Structural Properties of the Cambrian Semilattices -- Consequences of Semidistributivity [PDF]

, 2015
The $\gamma$-Cambrian semilattices $\mathcal{C}_{\gamma}$ defined by Reading and Speyer are a family of meet-semilattices associated with a Coxeter group $W$ and a Coxeter element $\gamma\in W$, and they are lattices if and only if $W$ is finite.

The facial weak order and its lattice quotients [PDF]

, 2016
We investigate a poset structure that extends the weak order on a finite Coxeter group $W$ to the set of all faces of the permutahedron of $W$. We call this order the facial weak order.

Regional Shopping Objectives in British Grocery Retail Transactions Using Segmented Topic Models

Applied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Understanding the customer behaviours behind transactional data has high commercial value in the grocery retail industry. Customers generate millions of transactions every day, choosing and buying products to satisfy specific shopping needs.

Exploring Alexithymia, Uncertainty, Anxious Arousal, and Social Anxiety as Mediators of the Relationship Between Sensory Processing Differences and Restricted and Repetitive Behaviors in Autistic Adults

Autism Research, EarlyView.
ABSTRACT Restricted and repetitive behaviors (RRB) are associated with sensory processing (SP) differences for autistic people, and are thought to be a coping strategy to help manage the sensory environment. Previous work shows that, for autistic people, alexithymia, intolerance of uncertainty (IU), and anxiety mediate the relationship between SP ...

Isotopic evidence for temperate oceans during the Cambrian Explosion

Scientific Reports, 2019
The Cambrian Explosion was a key event in the evolution of life on Earth. This event took place at a time when sea surface temperatures have been proposed to reach about 60 °C. Such high temperatures are clearly above the upper thermal limit of 38 °C for

Welsh Basin [PDF]

, 2011
The Cambrian rocks of Wales mostly lie within the Avalon composite terrane, apart from a small area of Cambrian rocks of the Monian composite terrane that is discussed in Chapter 9.

An analogue of distributivity for ungraded lattices [PDF]

, 2005
In this paper, we define a property, trimness, for lattices. Trimness is a not-necessarily-graded generalization of distributivity; in particular, if a lattice is trim and graded, it is distributive.

“The purpose of activism is to educate”: Young people's climate activism as and for education in the youth strike movement in England

British Educational Research Journal, EarlyView.
Abstract By skipping school for their cause, young climate strikers repeatedly demonstrated their priorities in 2019 and 2020. They regularly chose to sacrifice a day of their formal education in favour of collective action. This study asks what we can learn from the reflections of former youth strikers.
