In this paper, we present the simulation of a simple, yet significantly powerful, sequential model by cellular automata. The simulated model is called oblivious multi-head one-way finite automata and is characterised by having its heads moving only forward, on a trajectory that only depends on the length of the input. While the original finite automaton works in linear time, its corresponding c...

This is an attempt to expose the essence of Samuelson's consumptionloan paradox. It is maintained that the double infinity of traders and dated commodities allows for competitive equilibria that are not Pareto-optimal. While such models are most interesting in the dynamic setting, the fact that generations do not meet is not essential. The chain-letter aspect of the model reminds us that the ap...

One of the main problems faced by university students is to create and manage the semester course plan. In this paper, we present a course enrollment recommender system based on data mining techniques. The system mainly helps with students’ enrollment decisions. More specifically, it provides recommendation of selective and optional courses with respect to students’ skills, knowledge, interests...

A previously unknown coronavirus was isolated from the sputum of a 60-year-old man who presented with acute pneumonia and subsequent renal failure with a fatal outcome in Saudi Arabia. The virus (called HCoV-EMC) replicated readily in cell culture, producing cytopathic effects of rounding, detachment, and syncytium formation. The virus represents a novel betacoronavirus species. The closest kno...

Laboratory Directors assume responsibility for the quality of data that is reported from their laboratories. A recent publication reminds us that the laboratory is likely to see contradictory data when comparing in-house interference data to information reported on the package insert (1). However, the quality of interference testing data provided by the manufacturer is seldom questioned, and, i...

Posterior Reversible Encephalopathy Syndrome (PRES) refers to a disorder of reversible subcortical vasogenic oedema in patients with acute neurological symptoms. Its clinical manifestations include seizures, visual disturbances, headache, confusion, impaired consciousness, ataxia, and other focal neurological signs. It is a complex and multidisciplinary disease with the pathophysiological chang...

The dogmatics of the distribution competences benefits from a theory competences, because latter reminds former complexity and plurality as well relativity contingency competence relations. In this way, encourages to develop concepts arguments that are more viable suitable, but less systematic‐smooth universal. particular, critical sustainably shakes self‐evidence with which essence or natu...

The bar soap is one of the mostly used cleaning agents for centuries. After use soap, there some residues that cause a squeaky feeling which favorable consumers because it reminds cleanliness. However, do not like it. In this study, reasons why occured after using soaps were investigated. Through ex vivo and in tests, was found on skin due to magnesium sodium salts ions hard water. These result...
