We consider a quasistatic quantum Otto cycle using two effectively two-level systems with degeneracy in the excited state. The systems are coupled through isotropic exchange interaction of strength J>0, in the presence of an external magnetic field B which is varied during the cycle. We prove the positive work condition and show that level degeneracy can act as a thermodynamic resource, so that...

Transportation-related injuries are a leading cause of pediatric death, and effective interventions are limited. Otto the Auto is a website offering engaging, interactive activities. We evaluated Otto among a sample of sixty-nine 4- and 5-year-old children, who participated in a randomized parallel group design study. Following baseline evaluation, children engaged with either Otto or a control...

We study the effect of Kerr nonlinearity in quantum thermal machines having a Kerr-nonlinear oscillator as working substance and operating under ideal Otto cycle. first investigate efficiency heat engine show that by varying strength surpasses up to 2.5 times harmonic engine. Moreover, Kerr-nonlinearity makes coefficient performance refrigerator be large 3 refrigerators. These results were obta...

We study a minimal quantum Otto heat engine, where the working medium consists of an interacting few-body system in harmonic trap. This allows us to consider interaction strength as additional tunable parameter during work strokes. calculate figures merit this engine function temperature and show clearly which regimes interactions assist performance. also finite-time dynamics subsequent tradeof...

Otto Mangold [5] was an early-twentieth-century embryologist who specialized in the development of amphibian embryos. A major emphasis of his research was refining the concept of the organizer [6], now referred to as embryonic induction [7]. He was born on 4 November 1891 in Auenstein, Germany, and came from what Viktor Hamburger [8], a colleague and personal acquaintance, described as ?peasant...

To enable knowledge access across languages, ontologies that are often represented only in English, need to be translated into different languages. For this reason, we present OTTO, an OnTology TranslatiOn System, which enhances ontologies with multilingual information. Rather a different task than the classic document translation, ontology label translation faces highly specific vocabulary and...
