Title: Protein and peptide nanoarrays
Inventor: MIRKIN CHAD A
IPC: C07K1/04
Filed: 2002-10-02
Granted: 2012-07-03
Abstract: Ultrahigh resolution patterning, preferably carried out by dip-pen nanolithographic printing, can be used to construct peptide and protein nanoarrays with nanometer-level dimensions. The peptide and protein nanoarrays, for example, exhibit almost no detectable nonspecific binding of proteins to their passivated portions. This work demonstrates how dip pen nanolithographic printing can be used in a method to generate high density protein and peptide patterns, which exhibit bioactivity and virtually no non-specific adsorption. It also shows that one can use AFM-based screening procedures to study the reactivity of the features that comprise such nanoarrays. The method encompasses a wide range of protein and peptide structures including, for example, enzymes and antibodies. Features at or below 300 nm can be achieved.

Abstract: A finned tube water heater has a pair of flow manifolds each having a water inlet and a water outlet and a series of connecting openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. A burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle.

Abstract: Un système de capteur distribué d'analyse optique dans le domaine temporel de Brillouin (BOTDA) et de la méthode d'utiliser une onde continue (oc) de Stokes interrompue par une impulsion sombre pour une meilleure résolution spatiale. L'onde continue de Stokes entraîne un épuisement continu de l'onde de pompage. L'impulsion sombre entraîne l'arrêt pour la durée de l'impulsion. Les interactions de Brillouin sont mesurées lors de l'impulsion sombre. Des impulsions sombres très étroites peuvent être utilisées, car suffisamment d'énergie d'onde de Stokes est maintenue. Le système produit un signal plus fort dans le domaine temporel et un spectre de Brillouin de largeur de ligne plus étroite que les techniques conventionnelles en utilisant une impulsion lumineuse de Stokes. Des impulsions de mesure plus étroites peuvent être utilisées permettant d'améliorer la résolution spatiale. Une onde de Stokes quasi continue peut être utilisée pour réduire l'effet de diffusion de Brillouin stimulée (SBS) dans les fibres de mesure longues. Le système peut être utilisé pour des mesures de contrainte ou de température distribuées.

Abstract: One embodiment of the present invention provides a system that facilitates encryption of data within a column of a database. The system operates by first receiving a command to perform a database operation. Next, the system parses the command to create a parse tree. The system then examines the parse tree to determine if a column referenced in the parse tree is an encrypted column. If a column referenced in the parse tree is an encrypted column, the system automatically transforms the command to include one or more cryptographic commands to facilitate accessing the encrypted column while performing the database operation.
