Intravesical catheter knotting: an unusual complication of suprapubic catheterization

open access: yesThe Turkish Journal of Pediatrics, 2016
Suprapubic catheterization is commonly used to drain urine temporarily from the bladder. Although it is a commonly performed procedure, it is not without complications. Many of these complications related to surgical technique.

TORUS KNOTS ARE FOURIER-(1,1,2) KNOTS [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2009
Every torus knot can be represented as a Fourier-(1,1,2) knot which is the simplest possible Fourier representation for such a knot. This answers a question of Kauffman and confirms the conjecture made by Boocher, Daigle, Hoste and Zheng. In particular, the torus knot Tp,q can be parameterized as [Formula: see text]

Knot complexity and the probability of random knotting [PDF]

open access: yesPhysical Review E, 2002
The probability of a random polygon (or a ring polymer) having a knot type $K$ should depend on the complexity of the knot $K$. Through computer simulation using knot invariants, we show that the knotting probability decreases exponentially with respect to knot complexity. Here we assume that some aspects of knot complexity are expressed by the minimal

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

CATEGORICAL GROUPS, KNOTS AND KNOTTED SURFACES [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2007
We define a knot invariant and a 2-knot invariant from any finite categorical group. We calculate an explicit example for the Spun Trefoil.

Thermoresponsive Liquid Crystalline Polymer Coatings Programmed by Field‐Induced Topological Defects for Tunable Optical and Topographical Responses

open access: yesAdvanced Functional Materials, EarlyView.
Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...

Pathogenicity of the root-knot nematode Meloidogyne javanica on potato [PDF]

open access: yes, 2005
Host–parasite relationships and pathogenicity of Meloidogyne javanica on potatoes (newly recorded from Malta) were studied under glasshouse and natural conditions. Potato cvs Cara and Spunta showed a typical susceptible reaction to M. javanica under

Helsinská smlouva - internacionalizace severské spolupráce

open access: yesČasopis pro Právní Vědu a Praxi, 2003
Jestliže se v průběhu první dekády existence Sever­ské rady objevovaly pochybnosti o její mezinárodně­ právní povaze (neexistence mezinárodní smlouvy, ja­kožto obvyklého instrumentu k založení mezinárodní organizace), pak rok 1962 tyto nejasnosti do ...
