Arthroscopic Technique for Posterior Labral Repair in the Beach‐Chair Position

Arthroscopy Techniques, EarlyView.
Abstract Posterior labral repair is commonly performed in the lateral decubitus position; however, comparable outcomes have been reported using the beach‐chair position. Limited visualization of the posterior‐inferior glenoid remains a perceived disadvantage of the beach‐chair setup.

Machine learning of knot topology in non-Hermitian band braids

Communications Physics
The deep connection among braids, knots and topological physics has provided valuable insights into studying topological states in various physical systems. However, identifying distinct braid groups and knot topology embedded in non-Hermitian systems is

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Teichmüller Theory of Bordered Surfaces

Symmetry, Integrability and Geometry: Methods and Applications, 2007
We propose the graph description of Teichmüller theory of surfaces with marked points on boundary components (bordered surfaces). Introducing new parameters, we formulate this theory in terms of hyperbolic geometry.

Subgroup separability of surface braid groups and virtual braid groups

International Journal of Algebra and Computation
In this paper, we give a complete characterization of subgroup separability (also known as LERF property) for surface braid groups and virtual (singular) braid groups. More specifically, for a given surface S let [Formula: see text] be the n-string pure braid group of S. We prove that if S is large then [Formula: see text] is not LERF for [Formula: see

Empowering Circular Startups: Unveiling the Blueprint for Circular Business Models

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular startups are increasingly recognized as key drivers in the transition toward a circular economy. Yet the business models (BMs) through which these startups operationalize circularity remain poorly understood, limiting the ability of entrepreneurial ecosystem actors to offer effective support.

Intersection of parabolic subgroups in Euclidean braid groups: a short proof

Comptes Rendus. Mathématique
We give a short proof for the fact, already proven by Thomas Haettel, that the arbitrary intersection of parabolic subgroups in Euclidean Braid groups $A[\tilde{A}_n]$ is again a parabolic subgroup. To that end, we use that the spherical-type Artin group

Hurwitz components of groups with socle PSL(3, q)

Extracta Mathematicae, 2021
For a finite group G, the Hurwitz space Hinr,g(G) is the space of genus g covers of the Riemann sphere P1 with r branch points and the monodromy group G. In this paper, we give a complete list of some almost simple groups of Lie rank two.
