Distribution width

The transient current, derivable from equation 1, is given in equations 2 and 3 where T is the transit time and I is the absorbed photon flux. The parameter a can be further derived as equation 4 (4), where Tis the absolute temperature and is the distribution width (in units of kT) of a series of exponential traps. In this context, the carrier mobdity is governed by trapping and detrapping processes at these sites.

The measurements extrapolate to generate a 0 K value of Tcross at a size-distribution width of approximately 3%. The authors argue that these results imply that it may be possible to observe a true metallic conductivity to near 0 K in a 2D nanocluster array, giving a sufficiently narrow size distribution. 

From comparable systems with a particle-size distribution width of 7%, experimental and computational results for temperature-dependent conductivity measurements were reported on by Remade et al. [57]. At low temperatures, the I(U) characteristics have a sigmoid shape and are non-linear (Figure 25). 

Red blood cell distribution width (RDW) Reticulocyte count 11.5-14.5% (0.115-0.145) A higher value means the presence of many different sizes of RBCs the MCV is therefore less reliable. 

Ck-2H and Cf 2H bonds attach to a common motional axis, i.e., the Os Cf bond. The distribution width of /cLAM is estimated to be 1.3 on a log scale. The results for several other temperatures are shown in Fig. 21(c)-(h). The parameters obtained are summarized in Table 1. 

Figure 4.13. Intensity Stem-Vo I met plot for a double Gaussian distribution of lifetimes as a function of distribution width K. The two lifetimes are 5 and 15 with bimolecular quenching rate constants of 0.30 and 0,01, respectively. Theunqucnchcd intensity contribution is 0.5 for each lifetime. The R for each distribution is indicated next to the curve. (Adapted from Ref. 54.)...

Without an appreciation for the possible spread of sizes in real particulate systems the values of a in Fig. 11.6 are merely those of an adjustable parameter. We therefore give distribution widths for some natural and artificial aerosols and hydrosols in Table 11.1 we excluded from this list broad distributions, such as raindrops, to which the notion of a width is not really applicable. 

Fig. 2.14 (a) Ion energy distributions of the doubly charged Ir ions. The distribution width is very narrow without a low energy tail and therefore there is no evidence of post field ionization of field evaporated Ir2+ ions. Evaporation field calculations for low temperatures indicate that Ir will first field evaporate as Ir2+ ions when the field is gradually raised. 

Fuhs et al.m investigated P p0 Aj in multilayers of Synechocystis PCC 6803 oriented on mylar sheets by transient W-band EPR. They could show an enhanced resolution of structural parameters of the RP in this model system. A problem is the uncertainty of the orientation distribution (width 30 10°). Limitations and possibilities of the method are discussed in this work. The technique is interesting for all systems for which no single crystals are available. 

The Na+/proline transporter of E. coli (PutP) is an integral membrane protein that is proposed to contain 13 transmembrane helices.85 Four-pulse DEER measurements found distances of 48,22, and 18 A for three doubly spin-labelled variants.The 48 A distance confirmed that those two labels were on opposite sides of the membrane. The large distance distribution widths that were observed in the pair functions reveal the substantial flexibility of the loop regions to which the spin labels were attached. 

Abstract. A multi-wavelength, multi-sensor Look-Up-Table (LUT) algorithm has been developed to retrieve information about stratospheric aerosols from satellite-based observations of particulate extinction. Specifically, the LUT algorithm combines extinction measurements from SAGE n with similar measurements from the CLAES instrument, and uses the composite spectra in month-latitude-altitude bins to retrieve values and uncertainties of particle effective radius, surface area, volume and size distribution width.
