Deep NIR-I Emissive Iridium(III) Complex Bearing D-A Ligand: Synthesis, Photophysical Properties and DFT/TDDFT Calculation

Crystals, 2021
Near-infrared (NIR) phosphorescent iridium(III) complexes have been demonstrated to possess photophysical properties superior to those of traditional NIR dyes. However, the NIR emission wavelength is restricted in the range of 700–800 nm.

Lifetime of kaonium [PDF]

Physical Review D, 2004
The kaon--antikaon system is studied in both the atomic and the strongly interacting sector. We discuss the influence of the structures of the $f_0(980)$ and the $a_0(980)$ mesons on the lifetime of kaonium. The strong interactions are generated by vector meson exchange within the framework of the standard $SU(3)_V\times SU(3)_A$ invariant effective ...

Measurement of the Ds Lifetime [PDF]

, 1998
We report the results of a precise measurement of the Ds meson lifetime based on 1662 +/- 56 fully reconstructed Ds -> phi pi decays, from the charm hadroproduction experiment E791 at Fermilab.

Measuring lifetime poverty [PDF]

Journal of Economic Theory, 2011
The paper provides an axiomatic framework necessary to investigate the lifetime poverty for an individual as well as for the society, and to identify the appropriate axioms for their measurement. It further suggests that consumption rather than income is a more accurate measurement of the standard of living over time, especially in the context of ...

Development of Precise Lunar Orbit Propagator and Lunar Polar Orbiter’s Lifetime Analysis [PDF]

Journal of Astronomy and Space Sciences, 2010
To prepare for a Korean lunar orbiter mission, a precise lunar orbit propagator; Yonsei precise lunar orbit propagator (YSPLOP) is developed. In the propagator, accelerations due to the Moon’s non-spherical gravity, the point masses of the Earth, Moon,

Emission Modes in Electrospray Thrusters Operating with High Conductivity Ionic Liquids

Aerospace, 2020
Electrospray thruster life and mission performance are strongly influenced by grid impingement, the extent of which can be correlated with emission modes that occur at steady-state extraction voltages, and thruster command transients.

Estimating mean lifetime [PDF]

Proceedings of the National Academy of Sciences, 2003
The life expectancy implied by current age-specific mortality rates is calculated with life table methods that are among the oldest and most fundamental tools of demography. We demonstrate that these conventional estimates of period life expectancy are affected by an undesirable “tempo effect.” The tempo effect is positive when the mean age at death is

On Uncertain Lifetimes [PDF]

Journal of Political Economy, 1977
This paper contrasts consumer choice under uncertain lifetimes with the behavior that would arise if each individual's lifetime were announced at birth. In a model that includes life insurance and excludes investments in human capital, the expected utility under uncertain lifetimes exceeds that under known lifetimes when the latter expectation is based
