Accelerating kernel principal component analysis (KPCA) by utilizing two‐dimensional wavelet compression: applications to spectroscopic imaging
Authors: Luttrell Robert D. , Vogt Frank
Published: June 2008

Principal component analysis (PCA) is a standard tool for analyzing spectroscopic data. However, PCA can at most discriminate a number of spectroscopic signatures that is either equal to the number of variables or to the number of samples, whichever is smaller. Furthermore, linear algorithms are not well adapted to model nonlinear relationships present in the data. In order to overcome the limitations imposed by linear algorithms when applied to nonlinear data, Kernel Principal Component Analysis (KPCA) has been developed. Unlike PCA, KPCA is able to extract a number of principal components (PCs) that exceeds the number of variables, if the number of samples is greater. Because spectroscopic imagers acquire up to tens of thousands of spectra, KPCA computations often require multiple gigabytes of RAM just for holding data. This prohibits the routine application of KPCA to spectroscopic imaging especially if calculations are run on personal computers. In order to avoid such situations, a wavelet compression algorithm is presented that never has to hold all data in memory. The main goal here is to enable the application of KPCA, including mean centering, to large datasets. For this purpose, a mean‐centering technique that is compatible with the compression has also been developed. For assessing this compression method, the figures of merit ‘reduction in memory requirements’, ‘quality of compression‐based models’ and ‘gains in computation speed’ are studied. These analyses are performed at different compression levels. For testing purposes, spectroscopic imaging data acquired from bacterial samples and remote sensing are used. The results demonstrate that the proposed compression‐based KPCA algorithm is (a) feasible on personal computers and (b) derives good approximations of the models determined by the memory‐demanding uncompressed KPCA.

De‐racemization of Enantiomers versus De‐epimerization of Diastereomers—Classification of Dynamic Kinetic Asymmetric Transformations (DYKAT)
Authors: Steinreiber Johannes , Faber Kurt , Griengl Herfried
Published: June 2008

The isolation of single stereoisomers from a racemic (or diastereomeric) mixture by enzymatic or chemical resolution techniques goes in hand with the disposal of 50 % (racemate) or more (diastereomeric mixtures) of the “undesired” substrate isomer(s). In order to circumvent this drawback, dynamic systems have been developed for the de‐racemization of enantiomers and the de‐epimerizations of diastereomers. Key strategies within this area are discussed and are classified according to their underlying kinetics, that is, dynamic kinetic resolution (DKR), dynamic kinetic asymmetric transformations (DYKAT), and hybrids between both of them. Finally, two novel types of DYKAT are defined.
Label‐Free Fluorescent Probing of G‐Quadruplex Formation and Real‐Time Monitoring of DNA Folding by a Quaternized Tetraphenylethene Salt with Aggregation‐Induced Emission Characteristics

Biosensing processes such as molecular beacons require non‐trivial effort to covalently label or mark biomolecules. We report here a label‐free DNA assay system with a simple dye with aggregation‐induced emission (AIE) characteristics as the fluorescent bioprobe. 1,1,2,2‐Tetrakis[4‐(2‐bromoethoxy)phenyl]ethene is nonemissive in solution but becomes highly emissive when aggregated. This AIE effect is caused by restriction of intramolecular rotation, as verified by a large increase in the emission intensity by increasing viscosity and decreasing temperature of the aqueous buffer solution of 1,1,2,2‐tetrakis[4‐(2‐triethylammonioethoxy)phenyl]ethene tetrabromide (TTAPE). When TTAPE is bound to a guanine‐rich DNA strand (G1) via electrostatic attraction, its intramolecular rotation is restricted and its emission is turned on. When a competitive cation is added to the G1 solution, TTAPE is detached and its emission is turned off. TTAPE works as a sensitive poststaining agent for poly(acrylamide) gel electrophoresis (PAGE) visualization of G1. The dye is highly affinitive to a secondary structure of G1 called the G‐quadruplex. The bathochromic shift involved in the G1 folding process allows spectral discrimination of the G‐quadruplex from other DNA structures. The strong affinity of TTAPE dye to the G‐quadruplex structure is associated with a geometric fit aided by the electrostatic attraction. The distinct AIE feature of TTAPE enables real‐time monitoring of folding process of G1 in the absence of any pre‐attached fluorogenic labels on the DNA strand. TTAPE can be used as a K+ ion biosensor because of its specificity to K+‐induced and ‐stabilized quadruplex structure.
Doping of C60 Fullerene Peapods with Lithium Vapor: Raman Spectroscopic and Spectroelectrochemical Studies
Authors: Kalbáč Martin , Kavan Ladislav , Zukalová Markéta , Dunsch Lothar
Published: June 2008

Raman spectroscopy and in situ Raman spectroelectrochemistry have been applied to the study of the lithium vapor doping of C60@SWCNTs (peapods; SWCNT=single‐walled carbon nanotube). A strong degree of doping was proven by the disappearance of the radial breathing mode (RBM) of the SWCNTs and by the attenuation of the tangential (TG) band intensity by two orders of magnitude. The lithium doping causes a downshift of the Ag(2) mode of the intratubular C60 by 27 cm−1 and changes the resonance condition of the encapsulated fullerene. In contrast to potassium vapor doping, the strong downshift of the TG band was not observed for lithium doping. The peapods treated with lithium vapor remained partially doped even when they were exposed to humid air. This was reflected by a reduction in the intensity of the nanotube and the fullerene modes and by the change in the shape of the RBM band compared with that of the undoped sample. The Ag(2) mode of the intratubular fullerene was not resolved after contact of the lithium‐doped sample with water. Lithium insertion into the interior of a peapod and its strong interaction with the intratubular fullerene is suggested to be responsible for the air‐insensitive residual doping. This residual doping was confirmed by in situ spectroelectrochemical measurements. The TG band of the lithium‐doped peapods did not undergo an upshift during the anodic doping, which points to the formation of a stable exohedral metallofullerene peapod.
Full Structure of the Carbohydrate Chain of the Lipopolysaccharide of Providencia rustigianii O34

A lipopolysaccharide isolated from an opportunistic pathogen of the Enterobacteriaceae family Providencia rustigianii O34 was found to be a mixture of R‐, SR‐, and S‐forms consisting of a lipid moiety (lipid A) that bears a core oligosaccharide, a core with one O‐polysaccharide repeating unit attached, and a long‐chain O‐polysaccharide, respectively. The corresponding carbohydrate moieties were released from the lipopolysaccharide by mild acid hydrolysis and studied by sugar and methylation analyses along with one‐ and two‐dimensional NMR spectroscopy and high‐resolution electrospray ionization mass spectrometry. As a result, the structures of the core and the O‐polysaccharide were established, including the structure of the biological repeating unit (an oligosaccharide that is preassembled and polymerized in biosynthesis of the O‐polysaccharide), as well as the mode of the linkage between the O‐polysaccharide and the core. Combining the structure of the carbohydrate moiety thus determined and the known structure of lipid A enabled determination of the full lipopolysaccharide structure of P. rustigianii O34.
Distinct Columnar and Lamellar Liquid Crystalline Phases Formed by New Bolaamphiphiles with Linear and Branched Lateral Hydrocarbon Chains

Published: June 2008

A universal building block for the convergent synthesis of a wide variety of different T‐shaped ternary amphiphiles was developed and used for the synthesis of a series of new liquid‐crystalline materials composed of a rigid biphenyl core with polar glycerol groups at both ends and linear or branched alkyl chains in a lateral position. In addition, compounds with bulky achiral (2,4,6‐trimethylphenoxy, adamantane‐1‐carboxylate, benzoate) or chiral (menthyl or cholesteryl) substituents attached to the end of the lateral alkyl chain were also investigated. In all cases the lateral chains were connected to the aromatic core by an ether linkage. The effect of the ether linking unit on mesophase stability and mesophase type is discussed with respect to conformational effects. The liquid‐crystalline phases were investigated by polarizing microscopy, calorimetry, and X‐ray diffraction of surface aligned samples. Upon enlarging the lateral chains a series of different polygonal cylinder phases was observed, which were replaced by lamellar phases and a non‐cylinder hexagonal columnar phase by further increasing the size of these substituents. Remarkably, only pentagonal, hexagonal, and giant hexagonal cylinder phases could be observed, whereas mesophases composed of cylinders with a smaller number of sides are missing. No distinct chirality effects were observed for the menthyl‐ and cholesteryl‐substituted compounds. However, the rodlike shape of the polycyclic cholesteryl core leads to a unique phase structure combining an organization of the alicyclic cholesteryl cores perpendicular to the layer planes and the aromatic biphenyl cores parallel to the layer planes.
