Generators of anharmonic binary sequences having predetermined harmonics equal to zero. Orders and modes of anharmonicity are defined. Generators are disclosed, permitting to generate sequences anharmonic at successive determined orders according to previously selected modes.

Yeast artificial chromosomes (YACs), nucleotide sequences and polypeptides derived therefrom. Their use in methods for the detection, diagnosis and therapy of Alzheimer's disease. Their use in the preparation of transfected cells and transgenic animals. Diagnostic kits for use in the methods of the invention.

Pseudo-random pulse or number sequences having a specified probability distribution are generated from other electrical signals having some other probability distribution in a way including transforming those signals to produce further signals directly or indirectly representing pulses or numbers in the desired probability distribution. The invention provides a generator for the initial probability distribution that is based on two chain-code generators with outputs taken jointly by exclusive-OR...

The present invention relates to a nucleic acid molecule encoding a human or canine GABA.sub.B receptor, or a conservative variant thereof.

A changer for sequentially exposing a plurality of film cassettes during patient X-ray procedures. A sequencer permits either automatic or semiautomatic operation of the changer. Means are further provided for selective vertical positioning of the changer with respect to an X-ray machine. Radiation detection means are optionally provided for controlling the sequencer.

Novel non-coding sequences isolated upstream of the human IRS-2 gene are disclosed as markers for the prediction and/or diagnosis of IRS-2 related metabolic disorders or diseases, such as diabetes. The sequences also fuction as markers in a method and assay for evaluating the insulin regulating, i.e. insulin sensitizing or inhibiting properties of drug candidate substances, e.g. a method and assay for high throughput screening. The sequences and/or information derived therefrom can also be used ...

A control system is disclosed for the control of sequential flow of functions in teletypewriters and data typewriters. Input signals are presented to the control system which release the carrying out of the functions. The control system produces output signals which correspond to individual steps of the functions to be carried out successively. A plurality of control units are provided in the control system with each of the control units being provided with a respective allocator. The control un...

The present invention relates to Drosophila genes and methods for their use. The invention provides nucleotide sequences of Drosophila genes, amino acid sequences of the encoded proteins, and derivatives (e.g., fragments) and analogs thereof. The invention further relates to fragments (and derivatives and analogs thereof) of proteins which comprise one or more domains of a Drosophila protein. Antibodies to Drosophila proteins, and derivatives and analogs thereof, are also provided. Also provided...

The present invention relates an isolated human Site-1 Protease promoter region. The invention also relates to screening methods for agents decreasing the expression of Site-1 protease and thereby being potentially useful for the treatment of medical conditions related to obesity and/or diabetes.

A method is disclosed for shaping a Fourier transform spectrum of an array of input data. The method may be used to produce a Fourier spectrum in which the moduli of the Fourier coefficients are all equal to one predetermined constant. This makes possible hologram synthesis with phase only transmittance and is an improvement over kinoforms where amplitude information must be discarded. The present method rests on the introduction of an auxiliary parity array of data which is interlaced with the ...
