Twin Steiner triple systems

open access: yesDiscrete Mathematics, 1997
A set of blocks of the form \(\{a,x,y\}, \{a,z,w\}, \{b,x,w\}, \{b,z,y\}\) in a Steiner triple system STS\((v)\) is called a Pasch configuration. Replacing these blocks by \(\{b,x,y\}, \{b,z,w\}, \{a,x,w\}, \{a,z,y\}\) produces a new STS\((v)\), which may or may not be isomorphic to the original design. This paper contributes to an investigation of the

M. E. Grant Duff, Philosophic Liberalism and the Global Liberal Cause

open access: yesHistory, EarlyView.
Abstract Historians disagree about how best to conceptualize nineteenth‐century British Liberalism in relation to its international contexts. This article argues that we can better understand the patterns involved by interrogating individuals who bridged the worlds of partisan politics and elaborated thought.

Some derived steiner triple systems

open access: yesDiscrete Mathematics, 1976
In this paper certain properties of Steiner triple systems are shown to be sufficient to ensure that it is a derived triple system. In particular it is shown that whenever a Steiner triple system (S, t) of order 2v+1 contains a partial subsystem (V, k) of order v that can be embedded in a derived triple system (V,) where ||=βk|+1, then the Steiner ...

Does Financial Statement Comparability Reduce Differences in Sentiment‐induced Investor Trading Behaviour?

open access: yesAbacus, EarlyView.
This study examines whether comparable financial information can mitigate differences between individual and institutional investors’ trading behaviour, particularly behaviour that is shaped by investor sentiment. The results indicate that the higher the comparability, the smaller the gap in trading behaviour driven by investor sentiment between ...

Beyond affirmation: Lessons from Tavistock —A psychoanalytic critique of identity certainty and institutional defence

open access: yesBritish Journal of Psychotherapy, EarlyView.
Abstract This paper offers a psychoanalytic critique of the affirmation model in gender identity care, drawing on clinical experience from the Tavistock Gender Identity Development Service (GIDS). It argues that institutional and therapeutic responses to gender distress in young people are increasingly shaped by pressures to affirm rather than to ...

Rotational Steiner triple systems

open access: yesDiscrete Mathematics, 1982
AbstractA Steiner triple system S(v) of order v is said to be k-rotational if it admits an automorphism consisting of a single fixed element and exactly k (v−1)k-cycles.In this paper we obtain the necessary and sufficient condition for the existence of 3· and 4-rotational Steiner triple systems.

Opioids in breast cancer: Between analgesia and modulation of tumour progression

open access: yesBritish Journal of Pharmacology, EarlyView.
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.

Complete Arcs in Steiner Triple Systems

open access: yesJournal of Combinatorial Theory, Series A, 1997
A complete arc in a Steiner triple system of order \(v\), \(\text{STS}(v)\), is a set of \(s\) points met by any block in at most two points and such that the 2-secant blocks cover all points outside the arc. The authors determine the spectrum of sizes of complete arcs in Steiner triple systems; namely, they prove the following theorem: If \(v\equiv 1,

Targeting protein–protein interactions with reversible covalent modalities: Non‐cysteine chemistries

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Protein–protein interactions (PPIs) are central to diverse cellular functions, and represent a rapidly expanding class of therapeutic targets. Advancements in covalent drug design have enabled small‐molecule drugs to overcome challenges associated with engaging these targets, such as limited durations of action and difficult‐to‐drug (expansive,

Entrepreneurial State as a Creative Destroyer: Comparison of Hong Kong and Singapore's Creative Industries

open access: yesCreativity and Innovation Management, EarlyView.
ABSTRACT This paper explores the limits of mission‐directed entrepreneurial states by drawing on the theory of recombinant innovation and F.A. Hayek's insights on the spontaneous growth of knowledge in society. First, the use of discretionary policymaking curtails the range of knowledge generated in the process of social interaction, limiting the scope
