Band 3 aggregation in the plane of the red blood cell (RBC) membrane is postulated to be important in the pathophysiology of hemolysis of dense sickle and normal RBCs. We used the fluorescence photobleaching recovery and polarized fluorescence depletion techniques to measure the lateral and rotational mobility of band 3, glycophorins, and phospholipid analogues in membranes of density-separated...

in this paper, a higher order continuum model is presented based on the cosserat continuum theory in 3d numerical simulation of shear band localization. as the classical continuum models suffer from the pathological mesh-dependence in strain softening models, the governing equations are regularized by adding the rotational degrees-of-freedom to conventional degrees-of-freedom. the fundamental r...

High-resolution spectroscopic techniques, such as microwave fluorescence excitation, and double-resonance spectroscopy, have been widely used to measure the rotational constants of neutral molecules and hence to determine their structures. In the case of polyatomic cations, 7] the use of such techniques faces various difficulties, even for cations in ground electronic states. The main difficult...

We report on the detection of a molecular band centered at ∼98 μm (∼102 cm), observed with the Infrared Space Observatory in the young Planetary Nebula NGC 7027. The band structure and intensity can not be reproduced by atomic fine structure lines, recombination lines or by the rotational emission of abundant molecules. We discuss the possible contribution of the low–energy bending modes of pur...

Two spectroscopic instruments, a 1/4 meter Ebert-Fastie spectrometer and a Michelson interferometer, were flown aboard the NCAR Electra during the ALOHA-90 campaign. These instruments were designed to carry out measurements of the brightnesses and rotational temperatures of the 02 Atmospheric (0-1) band and several OH Meinel bands simultaneously with sodium lidar observations. The spectrometer ...

The electroneutral exchange of chloride and bicarbonate across the human erythrocyte membrane is facilitated by Band 3, a 911 amino acid glycoprotein. The 43 kDa amino-terminal cytosolic domain binds the cytoskeleton, haemoglobin and glycolytic enzymes. The 52 kDa carboxyl-terminal membrane domain mediates anion transport. The protein is a functional dimer, in which the two subunits probably in...

In this article, the effects of rotation angle between upper and lower n-fold rotational symmetric nano-structures are studied. Various modes circular dichroism (single wavelength band, dual-wavelength bands, more than two bands) in band from 3.3 to 5 ?m realized. Circular up 0.798 observed. Meanwhile, sensitivity reconfigure strategy for opposite responses has been discussed. Based on Born-Kuh...
