We have observed unusual ferromagnetic properties in single-crystalline CoSi nanowire ensemble, in marked contrast to the diamagnetic CoSi in bulk. High-density freestanding CoSi nanowires with B20 crystal structure are synthesized by a vapor-transport-based method. The reaction of cobalt chloride precursor with a Si substrate produces high-aspect-ratio CoSi nanowires. The high-resolution trans...

It is an easy problem to find, by backward induction, the betting system that maximizes E(X20|X0), your expected fortune after the 20 days have passed. It is to bet all you have each day. On the last day, given you have fortune X19, to maximize E(X20|X19) you bet it all, b20 = X19, and your expected final fortune is (2/3)2X19 + (1/3)0 = (4/3)X19. Since E(X20|X18) = E(E(X20|X19)|X18) = (4/3)E(X1...

We studied the effects of water vapor on the efficiencies of resistive plate chambers with glass electrodes, operated in the streamer mode. With moisture in the chamber gas that has freon as a component (water vapor B1000 ppm), a decrease in the efficiency (B20%) has been observed after operating for a period of several weeks to a few months. From our study, the cause of the efficiency decrease...

The most recently replicated portion of the bacterial and T4 phage chromosome, selectively labeled by an extremely short radioactive pulse, can be isolated, after denaturation, as short DNA chains with an average sedimentation coefficient of 7-11S.1-3 This supports an hypothesis of discontinuous DNA chain growth, by which short stretches of DNA are synthesized at the replicating point and subse...

In this study, The model Mazda WL diesel engine,4-cylinder, 4 straight-line cylinder with biodiesel blends ratio of 0%, 15%, 20%, 25%, 30% derived from rubber seed oil and DO has been simulated on ANSYS FLUENT software to analyze fuel consumption characteristics. Experimental engine using (DO) (B15, B20, B25, B30) for a installed 2500 Ford Ranger cars. simulation results show that the average i...

The formation of a single phase is an important requirement for high-entropy ceramics (HECs) because precipitation unwanted phases generally degrades their functional properties. This paper provides useful guideline the single-phase HECs. First, metal elements constituting HECs can be divided into two groups: that have parent as stable and with same stoichiometry but different crystal structure...
