Higher composition

The objective of this project was to develop \(Ti{O_2}\) based multifunctional substrates through silver decoration, while simultaneously enhancing the photocatalytic performance of \(Ti{O_2}\) in the substrate. Employing Ag nanoparticles introduced additional functionality to the system, namely surface-enhanced Raman scattering (SERS), thus enabling the detection of trace amounts of organic molecules prior to their degradation, all with the same substrate.

In this thesis, motivated by the advantages of the generalized minimumnoise subspace (GMNS) method, recently proposed for array processing, we proposedtwo algorithms for principal subspace analysis (PSA) and two algorithms for tensor de-composition using parallel factor analysis (PARAFAC) and higher-order singular valuedecomposition (HOSVD).

Recombinant glycerol dehydratase ofKlebsiella pneumoniae was purified to homogeneity. The subunit composition of the enzyme was most probablya2b2c2 .When(R)- and (S)-propane-1,2-diolswere used independently as substrates, the rate with the (R)-enantiomer was 2.5 times faster than that with the (S)-isomer. In contrast to diol dehydratase,an iso-functional enzyme,the affinity of the enzyme for the (S)-isomer was essentially the same or only slightly higher than that for the (R)-isomer (Km(R) /Km(S) ¼1.5). ...

A new approach of predicting structural classes of protein domain sequences is presented in this paper. Besides the amino acid composition, the composition of several dipeptides, tripeptides, tetrapeptides, pentapeptides and hexapeptides are taken into account based on the step-wise discriminant analysis. The result of jackknife test shows that this new approach can lead to higher pre-dictive sensitivityand specificityfor reduced sequence similaritydatasets.

The composition of the chloroplast-localized protease complex, ClpP, from the green alga Chlamydomonas reinhardtiiwas characterized by nondena-turing electrophoresis, immunoblotting and MS. The detected ClpP complex has a native mass of
540 kDa, which is
200 kDa higher than ClpP complexes in higher plant chloroplasts, mitochondria or bacteria. The 540-kDa ClpP complex contains two nuclear-encoded ClpP proteins (ClpP3 and P5) and five ClpR (R1, R2, R3, R4 and R6) proteins, as well two pro-teins, ClpP1Land ClpP1H, both probably derived from the plastid clpP1 gene. ...

In the first three parts of this series, we considered quadratic, cubic and quartic rings (i.e., rings free of ranks 2, 3, and 4 over Z) respectively, and found that various algebraic structures involving these rings could be completely parametrized by the integer orbits of an appropriate group representation on a vector space. These orbit results are summarized in Table 1.

In the first two articles of this series, we investigated various higher analogues of Gauss composition, and showed how several algebraic objects involving orders in quadratic and cubic fields could be explicitly parametrized. In particular, a central role in the theory was played by the parametrizations of the quadratic and cubic rings themselves. These parametrizations are beautiful and easy to state.

Annals of Mathematics In our first article [2] we developed a new view of Gauss composition of binary quadratic forms which led to several new laws of composition on various other spaces of forms. Moreover, we showed that the groups arising from these composition laws were closely related to the class groups of orders in quadratic number fields, while the spaces underlying those composition laws were closely related to certain exceptional Lie groups.

Two centuries ago, in his celebrated work Disquisitiones Arithmeticae of 1801, Gauss laid down the beautiful law of composition of integral binary quadratic forms which would play such a critical role in number theory in the decades to follow. Even today, two centuries later, this law of composition still remains one of the primary tools for understanding and computing with the class groups of quadratic orders. It is hence only natural to ask whether higher analogues of this composition law exist that could shed light on the structure of other algebraic number rings and fields. ...
