Semiclassical Analysis of the Wigner $9J$-Symbol with Small and Large Angular Momenta

, 2011
We derive a new asymptotic formula for the Wigner $9j$-symbol, in the limit of one small and eight large angular momenta, using a novel gauge-invariant factorization for the asymptotic solution of a set of coupled wave equations.

Development of a Four‐Language Questionnaire to Investigate Environmental Risk Factors for the Development of Canine Atopic Dermatitis and to Monitor Disease Course and Progression

Veterinary Dermatology, Volume 37, Issue 1, Page 34-44, February 2026.
Background: The chronic and multifactorial character of canine atopic dermatitis (cAD) often leads to poor disease control and treatment dissatisfaction. Environmental factors are likely to contribute to the disease development and may play a more important role than assumed previously.

Effect of a Spray Containing Occlusive Agents, Humectants and Physiological Lipids on Skin Hydration of Healthy Dogs When Applied After Bathing With a Chlorhexidine 2%/Miconazole 2% Shampoo

Veterinary Dermatology, Volume 37, Issue 1, Page 140-147, February 2026.
Background: Normal hydration of the canine epidermis is imperative for cutaneous homeostasis. Xerosis may be encountered in canine atopic dermatitis and may be aggravated by topical antiseptics. Hypothesis and Objectives: To evaluate the hydrating properties and the safety of a spray (Sensiderm spray; MP Labo) when applied after shampooing healthy dogs

Antenatal Corticosteroid Administration and Childhood Respiratory Morbidity: A Regression Discontinuity Study

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 2, Page 263-271, January 2026.
ABSTRACT Objective To determine if routine administration of antenatal corticosteroids affects the risk of infant lower respiratory tract infection and/or childhood asthma. Design Linked population‐based cohort analysed using a regression discontinuity design, which better controls for confounding than standard observational studies.

Quantum groups, Yang-Baxter maps and quasi-determinants

, 2017
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang-Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

Quantum tetrahedra and simplicial spin networks

, 1998
A new link between tetrahedra and the group SU(2) is pointed out: by associating to each face of a tetrahedron an irreducible unitary SU(2) representation and by imposing that the faces close, the concept of quantum tetrahedron is seen to emerge.

Reconstruction of universal Drinfeld twists from representations

, 2004
Universal Drinfeld twists are inner automorphisms which relate the coproduct of a quantum enveloping algebra to the coproduct of the undeformed enveloping algebra.
