Lantern Demonstration of the Filtration Angle

Conduction Defects in the Heart (with Lantern Demonstration.)

whether the method, in addition to its undoubted scientific interest, yields any information having a direct bearing upon the problems of diagnosis, prognosis, and treatment. It must be admitted that in many cases no further knowledge is obtained by its use than can be derived from ordinary methods of examination. At the same time it may fairly be claimed for it that in some cases no other meth...

Applications of the Lantern Identity

The purpose of this note is to unify the role of the lantern identity in the proof of several finiteness theorems. In particular, we show that for every nonnegative integer m, the vector space (over the rationals) of type m (resp. T -type m) invariants of integral homology 3-spheres are finite dimensional. These results have already been obtained by [Oh] and [GL2] respectively; our derivation h...

Physiology Lab Demonstration: Glomerular Filtration Rate in a Rat.

Measurements of glomerular filtration rate (GFR), and the fractional excretion of sodium (Na) and potassium (K) are critical in assessing renal function in health and disease. GFR is measured as the steady state renal clearance of inulin which is filtered at the glomerulus, but not secreted or reabsorbed along the nephron. The fractional excretion of Na and K can be determined from the concentr...

A lantern lemma

We show that in the mapping class group of a surface any relation between Dehn twists of the form T j xT k y = M (M a multitwist) is the lantern relation, and any relation of the form (TxTy) k = M (where Tx commutes with M ) is the 2-chain relation. AMS Classification 57M07; 20F38, 57N05
