TWIST-SPUN KNOTS OF TWIST-SPUN KNOTS OF CLASSICAL KNOTS

Dalat University Journal of Science
A k-twist-spun knot is an (n+1)-dimensional knot in the (n+3)-dimensional sphere that is obtained from an n-dimensional knot in the (n+2)-dimensional sphere by applying an operation called a k-twist-spinning. This construction was introduced by Zeeman (1965). In this paper, we show that the m2-twist-spinning of the m1-twist-spinning of a classical knot

Structural Basis of Lymphangiogenic Receptor VEGFR‐3 Activation Mediated by Distinctive Clustering of the Ligand–Receptor Complex

Advanced Science, EarlyView.
VEGF‐C and its receptor VEGFR‐3 are critical for lymphangiogenesis. Cryo‐EM structures of the VEGFR‐3/VEGF‐C ectodomain complex reveal a canonical 2:2 ligand–receptor hetero‐tetramer that further assembles into higher‐order clusters beyond simple receptor dimerization.

5. On Knots [PDF]

Proceedings of the Royal Society of Edinburgh, 1878
At the last meeting of the Society I stated that I had just procured a remarkable essay by Listing, part of which bears on the subject of knots, and that I had found in it an example of a change of form not producible by the modes of deformation I had employed.It had for some time struck me as very singular that, thoug I could easily prove that (when ...

Preoperative FIB‐4 Index as a Potential Factor Associated With Severe Postoperative Complications and Endogenous Organ Failure After Hepatectomy for Hepatocellular Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
This study demonstrates that a preoperative FIB‐4 index ≥ 5.0 independently predicts severe complications and endogenous organ failure (EOF) following hepatectomy for hepatocellular carcinoma. By capturing structural liver fragility and systemic vulnerability, the FIB‐4 index enhances surgical risk stratification beyond traditional functional markers ...

Ileosigmoid knotting: a case report

, 2008
Background: Resection of gangrenous/non-viable bowel followed by primary anastomoses is known to be a viable option for treatment of ileosigmoid knotting. We here report a case of ileosigmoid knot and examined the options for treatment.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

American Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...
