Charm Lifetime
A review of the charmed meson and baryon lifetimes is presented. Our knowledge of charmed particle lifetimes has greatly improved over the past two years, a crucial rôle having been played by the E687 experiment at Fermilab, which has almost quadrupled the samples of D mesons. The lifetime ratios τ (D +)/τ (D 0) and τ (D + s)/τ (D 0) are now known with an accuracy of 1.7% and 3.7% respectively....
متن کاملCustomer Lifetime Value Models: A literature Survey
Abstract Customer Lifetime Value (CLV) is known as an important concept in marketing and management of organizations to increase the captured profitability. Total value that a customer produces during his/her lifetime is named customer lifetime value. The generated value can be calculated through different methods. Each method considers different parameters. Due to the industry, firm, business...
متن کاملLogic for a Lifetime Logic for a Lifetime
There has been an explosion of formal work in commonsense reasoning in the past fteen years, but almost no signiicant connection with work in building commonsense reasoning systems (cognitive or otherwise). We explore the reasons, and especially the ideal formal assumption of omniscience, reviewing and extending arguments that this is irreparably out of line with the needs of any real reasoning...
متن کاملMulticomponent lifetime-based pH sensors utilizing constant-lifetime probes.
A multicomponent luminescent sensor system is described that uses probe species with constant lifetimes to generate an analyte-dependent change in the apparent sensor lifetime. This new sensing scheme not only allows for lifetime-based measurement techniques to be applied to sensors that employ static quenching interactions but also provides the ability to vary the sensitivity of the sensor sys...
متن کاملImproving Lifetime of Strategic Information Network in Oil Supply Chain
Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...
