NASA tests too hasty?

Hypercoagulability: too many tests, too much conflicting data.

It is now possible to identify hereditary and acquired risk factors in a substantial percentage of patients presenting with a venous thrombotic event. The clinician is faced with an ever-growing number of laboratory tests that can be ordered in such patients, and there is considerable uncertainty as to how this information should be utilized in patient management. Some have argued that widespre...

Hasty Congregational Gradient Descent

Stepwise Gradient Descent (SGD) algorithms for online optimization converge to local minima of the relevant cost function. In this paper a globally convergent modification of SGD is proposed, in which several solutions of SGD are run in parallel, together with online estimates of the cost function and its gradient. As each SGD estimate reaches a local minimum of the cost, the fitness of the mem...

Martin-ll of Tests Can Help Too

We argue that Martin-LL of tests provide useful techniques in proofs involving Kolmogorov complexity. Our examples cover more areas: (1) logical deenability; we prove an analogue of the 0-1 Law for various logics in terms of structures with high Kolmogorov complexity, (2) probabilistic computation: we display a relation between the Kolmogorov complexity of the random strings on which a probabil...

Hasty conclusion about acupuncture for hypertension?

Hasty Conclusion About Acupuncture for Hypertension? To the Editor: In his editorial commentary, “Acupuncture for Hypertension,” Kaplan1 unequivocally concludes that, “acupuncture is of no value for the treatment of hypertension.” In their clinical trial, Macklin et al2 randomly assigned hypertensive subjects to 1 of 3 interventions using “individualized,” “standardized,” or “sham” acupuncture....
