Turing, ciphers and quanta [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Alan Turing has certainly contributed to a widespread belief that the quest for a perfect, unbreakable, cipher is a futile pursuit. The ancient art of concealing information has, in the past, been matched by the ingenuity of code-breakers, but no longer!

Survey sabotage: Insights into reducing the risk of fraudulent responses in online surveys

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Validity is a key element of many forms of research—particularly surveys, which are often used in health professions education research. A survey must accurately measure what it is intended to measure to be considered valid. This is becoming increasingly difficult in the age of artificial intelligence (AI), where “bots” (short for robots) are ...

Epithelial disruption drives mesendoderm differentiation in human pluripotent stem cells by enabling TGF-β protein sensing

open access: yesNature Communications, 2023
Fate specification in the mammalian epiblast rely on complex interactions between morphogens and tissue organization. Here, the authors highlight epithelial integrity as a key determinant of TGF-β activity and a mechanism guiding morphogen sensing and ...

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

open access: yesApplied 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.

Knowledge acquisition in science and the blurred boundary between perception and cognition

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper provides a critical and detailed study of what researchers in the fields of contemporary cognition and neuroscience have revealed about the blurred boundary between perception and cognition. We set out the arguments with a view to what researchers and teachers should now consider regarding the subtleties of their interrelationship ...

Zigzags in Turing Machines [PDF]

open access: yes, 2010
We study one-head machines through symbolic and topological dynamics. In particular, a subshift is associated to the subshift, and we are interested in its complexity in terms of realtime recognition. We emphasize the class of one-head machines whose subshift can be recognized by a deterministic pushdown automaton.

Widening participation in outward student mobility: Successes, challenges and opportunities

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This article utilises data obtained through evaluation processes at Northumbria University to contribute to the emerging discourse on widening participation and outward student mobility. The rationale behind the study stems from the significant financial and non‐financial benefits associated with higher education and the UK's ongoing efforts ...

Evaluation of the standard battery of in vitro genotoxicity tests to predict in vivo genotoxicity through mathematical modeling: A report from the 8th International Workshop on Genotoxicity Testing

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract In human health risk assessment of chemicals and pharmaceuticals, identification of genotoxicity hazard usually starts with a standard battery of in vitro genotoxicity tests, which is needed to cover all genotoxicity endpoints. The individual tests included in the battery are not designed to pick up all endpoints.

Development and assessment of a machine learning tool for predicting emergency admission in Scotland

open access: yesnpj Digital Medicine
Emergency admissions (EA), where a patient requires urgent in-hospital care, are a major challenge for healthcare systems. The development of risk prediction models can partly alleviate this problem by supporting primary care interventions and public ...

Convective Turing patterns

open access: yesPhysical Review Letters, 1993
Turing patterns involve regions of different chemical compositions which lead to density gradients that, in liquids, are potentially unstable hydrodynamically. Nonlinear hydrodynamics coupled with a model of Turing pattern formation show that convection modifies and coexists with some Turing patterns and excludes others, and thereby plays a significant
