Abstract:

An automated sequential assignment protocol for proteins is presented using heteronuclear 3D NMR. For the observed amino acid spin systems, the protocol includes an algorithm to determine their amino acid types. For the detected polypeptides, the protocol includes another algorithm to sequentially map them to the primary sequence. The former algorithm measures the similarity between the detected spin systems and the 20 standard amino acid patterns. Both chemical shift and topological likeness are considered. Knowing the amino acid types, the mapping algorithm assigns the detected polypeptides

Abstract:

Spectrally sparse signals arise in many applications of signal processing. A spectrally sparse signal is a mixture of a few undamped or damped complex sinusoids. An important problem from practice is to reconstruct such a signal from partial time domain samples. Previous convex methods have the drawback that the computation and storage costs do not scale well with respect to the signal length. This common drawback restricts their applicabilities to large and high-dimensional signals. The reconstruction of a spectrally sparse signal from partial samples can be formulated as a low-rank Hankel ma

Hypericum Perforatum is one of the medicinal plants that grows in Europe, Western Asia and Northern Africa and is distinguished by its golden yellow flowers. The common name of the plant is St. John&rsquo<br>s wort. From the time of the ancient Greeks down through the middle Ages, the plant was considered to be imbued with magical power

Abstract:

Implanted tissue engineered substitutes constitute dynamic systems, with remodeling mediated by both the implanted cells and the host. Thus, there exists a significant need for methods to monitor the function and morphology of tissue engineered constructs. Noninvasive monitoring using 1H Nuclear Magnetic Resonance (NMR) spectroscopy and imaging can prove to be the solution to this problem. Spectroscopy allows for assessment of cellular function through the monitoring of inherent metabolic markers, such as total-choline, while high resolution imaging enables the evaluation of construct morph

NMR spectroscopy provides a variety of information leading to an understanding of the properties of different materials.

Abstract:

Lanthanides have several specific properties which cannot be found for other elements in the periodic table. Among various applications of lanthanides, complexes of LnIII ions are used in medicine, e.g., as contrast agents in MRI, as luminescent probes or as radiopharmaceuticals, where their specific properties are important. These complexes must be kinetically inert to prevent release of highly toxic "free" LnIII ions. This requirement is fulfilled with pre-organized ligands such as analogues of H4dota (1,4,7,10- tetraazacyclododecane-1,4,7,10-tetraacetic acid). Many of important properties o
