The DET curve in assessment of detection task performance.

AF Martin, GR Doddington, T Kamm, M Ordowski… - Eurospeech, 1997 - apps.dtic.mil
We introduce the DET Curve as a means of representing performance on detection tasks that
involve a tradeoff of error types. We discuss why we prefer it to the traditional ROC Curve …

SHEEP, GOATS, LAMBS and WOLVES: a statistical analysis of speaker performance in the NIST 1998 speaker recognition evaluation.

GR Doddington, W Liggett, AF Martin, MA Przybocki… - ICSLP, 1998 - apps.dtic.mil
Performance variability in speech and speaker recognition systems can be attributed to many
factors. One major factor, which is often acknowledged but seldom analyzed, is inherent …

Phosphorylation of troponin I by protein kinase A accelerates relaxation and crossbridge cycle kinetics in mouse ventricular muscle

…, J Layland, S Palmer, JM Leiden, AF Martin… - Circulation …, 2001 - Am Heart Assoc
Phosphorylation of cardiac myofibrils by cAMP-dependent protein kinase (PKA) can increase
the intrinsic rate of myofibrillar relaxation, which may contribute to the shortening of the …

Impaired cardiomyocyte relaxation and diastolic function in transgenic mice expressing slow skeletal troponin I in the heart

…, BM Wolska, MO Stojanovic, AF Martin… - The Journal of …, 1999 - Wiley Online Library
1 To assess the specific functions of the cardiac isoform of troponin I (cTnI), we produced
transgenic mice that expressed slow skeletal troponin I (ssTnI) specifically in cardiomyocytes. …

Vibration and buckling of rectangular composite plates with variable fiber spacing

AW Leissa, AF Martin - Composite structures, 1990 - Elsevier
This is a summary of the first known work which analyzes the structural behavior of composite
plates having nonuniformly spaced fibers. The present investigation is limited to single …

[HTML][HTML] Turnover of cardiac troponin subunits. Kinetic evidence for a precursor pool of troponin-I.

AF Martin - Journal of Biological Chemistry, 1981 - Elsevier
The turnover of troponin-T, troponin-I, and troponin-C, under conditions closely
approximating a steady state, has been determined from the rate of incorporation of L-[4,5-3H]leucine …
