Preferred embodiments of the present invention are directed to systems for phase measurement which address the problem of phase noise using combinations of a number of strategies including, but not limited to, common-path interferometry, phase referencing, active stabilization and differential measurement. Embodiment are directed to optical devices for imaging small biological objects with light. These embodiments can be applied to the fields of, for example, cellular physiology and neuroscience. These preferred embodiments are based on principles of phase measurements and imaging technologies. The scientific motivation for using phase measurements and imaging technologies is derived from, for example, cellular biology at the sub-micron level which can include, without limitation, imaging origins of dysplasia, cellular communication, neuronal transmission and implementation of the genetic code. The structure and dynamics of sub-cellular constituents cannot be currently studied in their native state using the existing methods and technologies including, for example, x-ray and neutron scattering. In contrast, light based techniques with nanometer resolution enable the cellular machinery to be studied in its native state. Thus, preferred embodiments of the present invention include systems based on principles of interferometry and/or phase measurements and are used to study cellular physiology. These systems include principles of low coherence interferometry (LCI) using optical interferometers to measure phase, or light scattering spectroscopy (LSS) wherein interference within the cellular components themselves is used, or in the alternative the principles of LCI and LSS can be combined to result in systems of the present invention.

The present invention relates to method and computer systems that provide a personal genome indexer. The present invention provides an output that allows individuals to access publically available scientific resources through the “prism” of their unique genetic code. Individual genetic information is indexed with information from public databases (e.g., PubMed database) that contain genetic information about the condition and the risk allele, and public databases (e.g., MedLinePlus database) that provide information about the condition. In an aspect, the present invention provides an output display that correlates an individual's specific risk alleles with genetic information and associated phenotypic condition based on one or more references from a publically accessible database, and/or a link to consumer health information about the phenotypic condition.

The mechanism kinematic link isomorphism identification method includes the steps of (1) forming a topological graph corresponding to a mechanism kinematic link according to the structural mode of the mechanism kinematic link, (2) setting a genetic code of an adjacent matrix according to the topological graph, (3) taking adjacent matrixes, to be determined, of the two topological graphs, determining an objective function, (4) generating the initial antibody population at random, calculating adaptability of each individual, sequencing the individuals according to the adaptability, (5) taking the optimal saving strategy on the initial antibody population, (6) calculating the concentration of each individual, enabling the each individual concentration to be equal to a value obtained by dividing the total individual number in a population by the adjacent individual sum, (7) taking the optimal interaction strategy on the antibody population obtained in the step (5), (8) conducting the mutation operation, adopting the inverse operator to achieve the mutation operation, (9) combining the local search operator and the genetic algorithm, (10) forming the immunity genetic hybrid algorithm, and conducting the isomorphism identification operation on the mechanism kinematic link. The mechanism kinematic link isomorphism identification method overcomes the shortcoming that the immunity genetic hybrid algorithm can be easily restrained to local optimum.

A lentiviral vector system is described. The system comprises a lentiviral transfer vector and a packaging construct. The transfer vector comprises (a) a 5′ LTR; (b) a 3′ LTR comprising a polyadenylation signal; (c) a minimal packaging signal, (d) (i) at least one heterologous upstream enhancer (UE) sequences, and/or (ii) at least one additional copy of endogenous UE sequences operatively associated with said polyadenylation signal; and (e) a PRE. The packaging construct comprises a nucleic acid encoding and expressing a lentiviral Gag nucleic acid (preferably Gag and Pol). Preferably the lentiviral Gag nucleic acid is a mutated Gag nucleic acid containing one or more substitution mutations, wherein said mutated Gag nucleic acid encodes the same amino acid sequence as the corresponding unmutated Gag nucleic acid, but differs from the nucleic acid sequence of said corresponding unmutated Gag nucleic acid sequence due to the degeneracy of the genetic code. Preferably the packaging construct further comprises a heterologous nucleic acid encoding and expressing an adenovirus VA RNA. The transfer vector and packaging construct can be used together in a producer cell to produce viral particles.

This invention deals with an integrated morphological system, herein called a morphological genome (morph genome), for design applications. This is the genome that encodes all form and is similar in intent to the biological genome that encodes all living things by its genetic code. The morph genome comprises a finite set of morphological genes, each gene specifies a distinct group of morphological transformations, each group of transformations is defined by a group of independent topological, geometric or other parameters. The morph genes and their parameters are mapped within an integrated higher-dimensional framework, with each parameter being represented along a vector in higher-dimensional Euclidean space. Each distinct number associated with a parameter or a group of parameters is represented by a distinct point in this space and is referenced by the higher-dimensional Cartesian co-ordinates of that point. This space uses a combination of discrete and continuous values for these parameters. The specific co-ordinates of any point in the space represent a genetic code for the specific form being mapped at that point. The entire space is a map of the morph genome and encodes all possible morphologies. The morph genome can be used as a design tool to generate known and new forms for applications in all fields of design including architecture, product design, environments and spaces, building or engineering structures, graphics, art, sculpture, technological devices, etc. The underlying method for the model for the morph genome applies to other fields of knowledge for systematically organizing and creating new concepts, structures, designs, information and taxonomies. The morph genome can also provide a basis for an integrated, interactive modeling environment for computers. It is a pedagogical tool for discovery and invention as well. Other applications include a graphic code for encryption as an alternative to numeric codes, and a system for representing numbers as integers, rational numbers and real numbers.
