A microscopically assisted limited colectomy mouse model of early colon cancer
Animal Models and Experimental Medicine, EarlyView.Establishment, surgery, and evaluation process of a microscope‐assisted limited colon resection mouse model for early‐stage colon cancer. Abstract Background Currently, there is a lack of an adequate rodent model for investigating surgical techniques and comprehensive treatment options for patients with colorectal cancer (CRC).

How SU(2)$_4$ Anyons are Z$_3$ Parafermions
SciPost Physics, 2017 We consider the braid group representation which describes the non-abelian braiding statistics of the spin $1/2$ particle world lines of an SU(2)$_4$ Chern-Simons theory.

Journal of Knot Theory and Its RamificationsIn this paper, we study some subgroups and their decompositions in semi-direct product of the twisted virtual braid group [Formula: see text]. In particular, the twisted virtual pure braid group [Formula: see text] is the kernel of an epimorphism of [Formula: see text] onto the symmetric group [Formula: see text].

Metasurfaces and Metadevices for Topological Electromagnetic Waves
Advanced Physics Research, EarlyView.Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Machine learning of knot topology in non-Hermitian band braids
Communications PhysicsThe 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

The Anatomical Record, EarlyView.Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

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.

Quantized braided groups [PDF]
Journal of Mathematical Physics, 1994 Algebras that represent a generalization of both quantum groups, quantum supergroups, and braided groups are defined. They are given by a pair of solutions of the Yang–Baxter equation that satisfy some additional conditions. Several examples are presented.

The Anatomical Record, EarlyView.Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...
