We study biased Maker-Breaker positional games between two players, one of whom is playing randomly against an opponent with an optimal strategy. In this paper we consider the scenario when Maker plays randomly and Breaker is “clever”, and determine the sharp threshold bias of classical graph games, such as connectivity, Hamiltonicity, and minimum degree-k. We treat the other case, that is when...

To evaluate the ripening-dependent changes in phytonutrients, seven commercial cultivars (two general and five cherry) of tomatoes were cultivated under greenhouse conditions. Fruits were harvested at breaker, turning, pink, light red, and red stages of each cultivar, and antioxidant contents, color attributes, and antioxidant activities were measured. During ripening process, lycopene content ...

We have developed a simple and reproducible rat model of chronic colonic inflammation by the intraluminal instillation of a solution containing a “barrier breaker” and a hapten. Administration of the hapten 2,4,6-trinitrobenzenesulfonic acid (5-30 mg) in 0.25 ml of 50% ethanol as the “barrier breaker” produced dose-dependent colonic ulceration and inflammation. At a dose of 30 mg, trinitrobenze...

A numerical model for orthogonal cutting using the material point method was applied to woodcutting using a bench plane. The cutting process was modelled by accounting for surface energy associated with wood fracture toughness for crack growth parallel to the grain. By using damping to deal with dynamic crack propagation and modelling all contact between wood and the plane, simulations could in...

AIM To measure excessive electrical stimulus time during pulp testing via electromyography (EMG) in the anterior belly of the digastric muscle, voice and finger movement, and to determine whether excessive stimulus time could be attenuated by a specially designed automatic circuit breaker on the basis of the EMG signal. METHODOLOGY The signals from three human responses (EMG, finger and voice...

BACKGROUND Claims-based algorithms based on administrative claims data are frequently used to identify an individual's primary care physician (PCP). The validity of these algorithms in the US Medicare population has not been assessed. OBJECTIVE To determine the agreement of the PCP identified by claims algorithms with the PCP of record in electronic health record data. DATA Electronic healt...

Voltage Source Converter-High Voltage Direct Current (VSC-HVDC) is the most efficient and reliable method for electrical power transmission over long distances. The greatest challenge with VSC-HVDC system is that short-circuit faults damages the converter valves and the transmission network. The fault clearing time for the available DC breakers are not fast enough and reliable to provide adequa...

The continuity in the electric supply of the electric installations is becoming one of the main requirements of the electric supply network (generation, transmission, and distribution of the electric energy). The achievement of this requirement depends from one side on the structure of the electric network and on the other side on the avaibility of the reserve source provided to maintain the su...
