Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

The Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

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.

Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

Archaeology in Oceania, EarlyView.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

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

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

Continuous Sewing Machine‐Like Suture Provides Higher Failure and Yield Load Compared to Traditional Techniques for Meniscal Root Repair in a Biomechanical Porcine Model

Arthroscopy, EarlyView.
Purpose To evaluate the biomechanical performance of the sewing machine‐like suture (SMS) technique against three established techniques (two cinch‐loop (TCL), modified Mason‐Allen (MMA), and double Mason‐Allen (DMA)) for transtibial pull‐out repair of posterior medial meniscal root tear (PMMRT) in a porcine model.

All‐Inside Primary Anterior Cruciate Ligament Reconstruction Using a Combined Polyester Synthetic Graft and Gracilis Tendon Autograft: Modified Technique of a Hybrid 4 × 2 Graft Preparation

Arthroscopy Techniques, EarlyView.
Abstract Anterior cruciate ligament reconstruction is a frequently performed procedure in arthroscopic surgery, with rising rates paralleling the incidence of anterior cruciate ligament ruptures worldwide. Synthetic grafts, especially hybrid constructs combining artificial devices with autologous tissue, offer biomechanical advantages and potential ...

Patellar Tendon Repair With Gracilis Autograft Augmentation and Anchor Fixation

Arthroscopy Techniques, EarlyView.
Abstract Patellar tendon rupture is a severe injury that disrupts knee extensor continuity and requires prompt surgical management. Although primary repair remains the standard treatment, isolated suture repair may be insufficient in cases of poor tissue quality or high mechanical demand, making augmentation necessary.

A Single‐Bundle Anterior Cruciate Ligament Reconstruction Technique Using Quadrupled Semitendinosus Tendon With Tibial Double Knotless Anchor Fixation And Femoral Suspensory Fixation

Arthroscopy Techniques, EarlyView.
Abstract Anterior cruciate ligament (ACL) injury is a common sports injury and has a significant effect on knee function. Its injury can seriously affect athletic ability and quality of life and may lead to complications such as secondary osteoarthritis.
