Combinatorial Legendrian knot invariants : representation numbers
, 2019 The study of Legendrian knots lies within the larger elds of contact geometry and knot theory. The requirements for Legendrian invariance is strictly stronger than its topological analog, as there are Legendrian knots that are not Legendrian isotopic,

Early stages of tooth development in the harbor porpoise Phocoena phocoena
The Anatomical Record, EarlyView.Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

Wilson loop invariants from WN conformal blocks
Nuclear Physics B, 2015 Knot and link polynomials are topological invariants calculated from the expectation value of loop operators in topological field theories. In 3D Chern–Simons theory, these invariants can be found from crossing and braiding matrices of four-point ...

, 2017 At Right Angles met up with author Ramya to discuss her article on Knot Theory. Over coffee at Starbucks, Ramya adeptly made sense of a tangled bunch of wool which I had carried with me to try and see if Knot Theory could help me untangle the ...

Higher-dimensional knot groups and decision problems
, 2020 An $n$-knot is a locally flat PL $n$-sphere in $S^{n+2}$. We show that many decision problems about $n$-knot groups, $n \ge 3$, and groups of closed orientable surfaces in $S^4$, are unsolvable.

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.

Arthroscopy, EarlyView.Purpose To evaluate midterm outcomes of endoscopic proximal hamstring repair in a previously established cohort. Methods A retrospective study design was used for a midterm (minimum 6 years) follow‐up time. Patients completed the questionnaires over the phone or electronically on REDCap after consent. The questionnaires included the modified Harris Hip

, 2020 In this work we study knot theories with a parity property for crossings: every crossing is declared to be even or odd according to a certain preassigned rule.

Topology of the We: Ur-Ich, Pre-Subjectivity, and Knot Structures
Open PhilosophyThe concept of the collective “we” has recently gained renewed attention through philosophy’s we-turn, as proposed by Yasuo Deguchi, raising new questions about the nature of intersubjectivity and shared experience. This article revisits Edmund Husserl’s

Knot invariants and indefinite causal order [PDF]
QuantumWe explore indefinite causal order between events in the context of quasiclassical spacetimes in superposition. We introduce several new quantifiers to measure the degree of indefiniteness of the causal order for an arbitrary finite number of events and ...
