A new classiication theorem for links by the authors and Roger Fenn leads to computable link invariants. As an illustration we distinguish the left and right trefoils and recover the result of Carter et al that the 2-twist-spun trefoil is not isotopic to its orientation reverse. We sketch the proof the classiication theorem. Full details will appear elsewhere

Trefoil factors (TFF) are secretory products of mucin producing cells. They play a key role in the maintenance of the surface integrity of oral mucosa and enhance healing of the gastrointestinal mucosa by a process called restitution. TFF comprises the gastric peptides (TFF1), spasmolytic peptide (TFF2), and the intestinal trefoil factor (TFF3). They have an important and necessary role in epit...

south asians (sas), originating from the Indian subcontinent, are the largest ethnic minority in several European nations. Compared to Caucasian populations, sas have a higher incidence and severity of cardiovascular disease (CVD) and its complications at a younger age and have a 40-60% higher risk of disease-related mortality1-8. This has prompted the suggestion that sa CVD should be viewed as...
