Precision imaging is a collection of image sensing techniques involving ultra-high sensitivity, time accuracy, and dynamic range, as well as ultra-low noise. In fact, imaging biological processes often requires sub-milli-lux sensitivity to detect tiny leve ...

Recombination dynamics in a variety of InGaN/GaN quantum systems has been studied by time resolved photoluminescence (PL). We have discovered that the time-decay of PL exhibits a scaling law: the nonexponential shape of this decay is preserved for quantum ...
Let u : R3+1 -> H-2 be a Wave Map with smooth compactly supported initial data satisfying the smallness condition parallel to u[0]parallel to ((H) over dot3/2 x (H) over dot1/2) < epsilon for a sufficiently small epsilon > 0. In particular, the Wave Map ex ...
We report measurements of B meson decays to two kaons using 253fb-1 of data collected with the Belle detector at the KEKB energy-asymmetric e+e- collider. We find evidence for signals in B+→K̄0K+ and B0→K0K̄0 with significances of 3.0σ and 3.5σ, respective ...
The ultrafast relaxation of aq. Fe(II)-tris(bipyridine) upon excitation into the singlet metal-to-ligand charge-transfer band (1MLCT) was characterized by femtosecond fluorescence up-conversion and transient absorption (TA) studies. The fluorescence expt. ...
Numerical modelling of subsurface flow constructed wetlands (CWs) gained increasing interest during the last years. The main objective of the modelling work is, on the one hand, to increase the insight in dynamics and functioning of the complex CW system b ...
The anharmonic properties of low-dimensional carbon crystal lattices are reviewed. The energy and crystal momentum conservation rules in two- and one-dimensional crystals lead to a drastic reduction of the phase space available for anharmonic phonon decay. ...
This laser kinetics features of the electron decay of TiO2 in the presence of the Escherichia coli (E. coli) phosphatidyl-ethanolcholine (PE) and lipo-polysaccharides (LPS) cell wall components were are reported in this study. The interaction of the biomol ...
Abstract: Inert and optically active pseudo-octahedral CrIIIN6 and RuIIN6 chromophores have been incorporated by self-assembly into heterobimetallic triple-stranded helicates HHH-[CrLnL3]6+ and HHH-[RuLnL3]5+. The crystal structures of CrLnL36 (L ...
Intraband transitions around 1.5 mum are studied in PbSe quantum dots at room temperature. Femtosecond pump-probe measurements reveal induced absorption by photoexcited carriers up to higher energy levels and its relaxation. A dominant decay component has ...
