The First Lactate Threshold Is a Limit for Heavy Occupational Work

in the Heavy Quark Limit

We study B → φK and B → φXs decays in the heavy quark limit using perturbative QCD. The next leading order corrections introduce substantial modifications to the naive factorization results (more than 50%). The branching ratio Br(B → φK) is predicted to be in the range (FB→K 1 (mφ)/0.33)(3.5 ∼ 4.2)× 10−6 which is within the one σ allowed region from the central value of 6.2×10−6 measured by CLE...

Heavy-traffic Limit Theorems for the Heavy-tailed Gi/g/1 Queue Heavy-traac Limit Theorems for the Heavy-tailed Gi/g/1 Queue

The classic GI=G=1 queueing model of which the tail of the service time and/or the interarrival time distribution behaves as t ?v S(t) for t ! 1, 1 < v < 2 and S(t) a slowly varying function at innnity, is investigated for the case that the traac load a approaches one. Heavy-traac limit theorems are derived for the case that these tails have a similar behaviour at innnity as well as for the cas...

A Poisson Limit for the Un nished Work of SuperposedPoint

A non-parametric framework for estimating threshold limit values

BACKGROUND To estimate a threshold limit value for a compound known to have harmful health effects, an 'elbow' threshold model is usually applied. We are interested on non-parametric flexible alternatives. METHODS We describe how a step function model fitted by isotonic regression can be used to estimate threshold limit values. This method returns a set of candidate locations, and we discuss ...

Occupational Work Assessment

Static and dynamic work involving the arms and the legs was performed by 40 men seven weeks after myocardial infarction. Leg ergometry produced a significantly higher peak work load, systolic blood pressure (BPs), heart rate (HR), and HR X BPs X 10-2 product (DP) than did arm ergometry: 842 ± 178 vs 546 ± 135 kg-m/min, 176 ± 24 vs 154 ± 19 mm Hg and 256 ± 54 vs 219 ± 48 (SD). Peak heart rates w...
