Poisson Arrivals See Time Averages The PASTA property refers to the expected state of a queueing system as seen by an arrival from a Poison process. An arrival from a Poisson process observes the system as if it was arriving at a random moment in time. Therefore, the expected value of any parameter of the queue at the instant of a Poisson arrival is simply the long-run average value of that par...

S. M. Ulam’s contributions to biology are surveyed. The survey covers cellular automata theory, population biology, Fermi-Pasta-Ulam results, pattern recognition, and sequence similarity.

Considering the high interest in using pulses production of staple foods, including pasta, this study aimed at investigating effect pre-gelatinisation on overall quality pasta from red lentils. Pre-gelatinized flours showed a lower gelatinisation temperature (up to about 57 °C vs. 65 °C) and higher retrogradation tendency than native flour. Such changes resulted water absorption capacity 1.23 0...

Abstract. Alpine ecosystems are experiencing rapid change as a result of warming temperatures and changes in the quantity, timing phase precipitation. This turn impacts patterns processes ecohydrologic connectivity, vegetation productivity water provision to downstream regions. The fine-scale heterogeneous nature these environments makes them challenging areas measure with traditional instrumen...

BACKGROUND The metabolic syndrome markedly increases the risk of type 2 diabetes and cardiovascular disease, but the influence of dietary modification on insulin and glucose metabolism independent of weight loss is still poorly understood. OBJECTIVE Our aim was to test whether carbohydrate dietary modifications improve insulin sensitivity and secretion and glucose tolerance in overweight or o...

Despite their astrophysical relevance, nuclear pasta phases are relatively unstudied at high temperatures. We present molecular dynamics simulations of symmetric matter with several topologies `lasagna' a range temperatures to study the pasta-uniform transition. Using Minkowski functionals we quantify trends in occupied volume, surface area, mean breadth, and Euler characteristic. The amplitude...

Previous characterizations of rodent eating behavior have revealed that they use coordinated forepaw movements to manipulate food pieces. We have extended upon this work to develop a simple quantitative measure of forepaw dexterity that is sensitive to lateralized impairments and age-dependent changes. Rodents learn skillful forepaw and digit movements to manage thin pasta pieces, which they ea...

This study investigated and modeled the behavior of Listeria monocytogenes in egg salad and pasta salad as affected by mayonnaise pH (3.8, 4.2, 4.6, and 5.0) and storage temperature (4, 8, and 12 degrees C). At each storage temperature, L. monocytogenes was able to grow in both salads regardless of the mayonnaise pH. The lag-phase durations (LPD) of L. monocytogenes in egg salad ranged from 33 ...

Loss of function in the hands occurs with many brain disorders, but there are few measures of skillful forepaw use in rats available to model these impairments that are both sensitive and simple to administer. Whishaw and Coles previously described the dexterous manner in which rats manipulate food items with their paws, including thin pieces of pasta [Whishaw IQ, Coles BL. Varieties of paw and...
