The understanding, analysis and modelling of the fundamental limit of the sustained random write performance and endurance of Flash solid state drives (SSDs) are critical for Flash SSD vendors and storage system designers and practitioners. This not only helps design high-performance Flash SSDs, but also dictates how Flash can be integrated into today’s memory and storage hierarchy. This paper ...

Resting muscle length affects both maximum force production and force maintenance. The strength and force maintenance characteristics of the genioglossus as a function of resting muscle length have not been described. We hypothesized that genioglossus optimum length (L(o)) could be defined in vivo and that the ability of the genioglossus to sustain a given workload would decrease as resting len...

This study investigated experimentally the fracture properties, i.e., the fatigue strength, the resistance to crack propagation and the fracture toughness, of an acrylic bone cement (Cemex RX). The mean endurance limit was determined following the staircase method. The endurance limit was estimated at 9.2 MPa. The fatigue crack propagation rate was measured according to the ASTM E647 standard. ...

In the past, components under fatigue loading were designed by using an S-N curve and endurance limit according to very high cycle fatigue tests [1-3], fatigue strength to failure at a given life decreases as loading cycles increase. In other words, endurance limit is not observed for most materials, which is true for axle materials for rolling stock. An axle is one of the key components for st...

the purpose of this study was to investigate the interference effect of concurrent strength and endurance training on maximum strength and vo2max in non-athletes. for this purpose, 34 sedentary healthy men (mean age 22±1.18 years, height 173.61±6.48 cm, and weight 56.13±8.50 kg) voluntarily participated in this study. initially, subjects were randomly assigned to one of four training groups: st...

We evaluated the influence of a 14-wk endurance running program on the exercise-induced release of high-sensitivity cardiac troponin T (hs-cTnT) and NH2-terminal pro-brain natriuretic peptide (NT-proBNP). Fifty-eight untrained participants were randomized to supervised endurance exercise (14 wk, 3-4 days/wk, 120-240 min/wk, 65-85% of maximum heart rate) or a control group. At baseline and after...

This article traces the study of interrelationships between power output, work done, velocity maintained or distance covered and the endurance time taken to achieve that objective. During the first half of the twentieth century, scientists examined world running records for distances from < 100 m to > 1000 km. Such examinations were empirical in nature, involving mainly graphical and crude curv...

Purpose. We investigated the relationship between selected variables of anthropometry and training with race performance during a 26.4 km open-water ultra-endurance swim at 23 °C in male master ultra-swimmers. Basic procedures. Fifteen non-professional male open-water ultra-endurance swimmers who were (mean ± SD) 40.0 (8.2) years of age with 83.7 (10.3) kg body mass, 1.80 (0.08) m body height a...

A new type of athlete is appearing in the offices of sports dietitians: formerly obese people who have undergone gastric bypass surgery and now aspire to be marathoners, triathletes, and other types of endurance athletes. The standard nutrition advice offered to bypass patients is contrary to the standard sports advice given to athletes. Bypass athletes need to limit carbohydrates, fluids, and ...
