摘要:
Disclosed herein are magic size nanoclusters comprising lead and one or more chalcogens. The disclosed magic size nanoclusters have both spectrally narrow fluorescence and ultra-high quantum efficiencies. Further disclosed herein is a method for preparing PbS, PbSe, and PbTe magic size nanoclusters. The yield of magic size nanoclusters can be increased by using anion sources enriched for secondary phosphines. The use of enriched secondary phosphine anion sources also increases the yield of quantum nanostructures.

Current data archiving and storage solutions seek to store data in the most accessible manner possible, often foregoing security for sake of user convenience. The technology, system, and methods proposed in this document seek to protect data in a highly resilient, secure manner, suitable for extremely long-term periods of time without loss of data integrity. The proposed solution includes methods for storing digital data, validating the integrity of the data on both sides of the transmission, encryption with keys that only the user has access to, splitting files into obfuscated slices for increased security, and determining the most effective storage location according to a novel cost metric.

An assembly for use with a syringe having a barrel and a needle includes a sealing element surrounding and positioned over at least a portion of the distal end of the syringe. An adapter at least partially surrounds the sealing element and is positioned over the distal end of the syringe. The adapter has a first skin contacting surface positioned at a distal end thereof. At least a portion of the first skin contacting surface extends generally parallel to at least a terminal end of the needle. The adapter also has a second skin contacting surface positioned proximally relative to the terminal end of the needle and at an angle to the first skin contacting surface. A needle shield at least partially surrounds and is removably positioned over at least one of the adapter, the sealing element and the syringe barrel.

A computer implemented process encompasses the following steps: Identify the user's current media content library/ies; Analyze the content of those libraries, deriving a “taste signature” for the user from that analysis; Match the derived “taste signature” to other media content and to other users; and provide the user with recommendations based on that automatic matching process.

An intradermal injection adapter includes a body having a longitudinal axis and a central portion located distally relative to the body along the longitudinal axis. The central portion has a cannula channel therethrough extending generally parallel to the longitudinal axis. A cannula within the cannula channel has a sharpened tip for injection into a patient and a sharpened opposite proximal end for injection into a pen injector. A distal protrusion has a first skin contacting surface extending generally parallel to the longitudinal axis. The first skin contacting surface is spaced from the cannula such that a distal portion of the cannula extends generally parallel to the first skin contacting surface.

A system (100) for connecting a fuel cell stack to an A.C. grid to provide power thereto is disclosed in which a voltage regulated D.C. bus (110) is provided to be coupled to the fuel cell stack, a bidirectional inverter (120) is coupled to the D.C. bus (110), and is to be coupled between the D.C. bus (110) and the A.C. grid. At least one D.C. auxiliary load (130) of the fuel cell stack is provided coupled to the D.C. bus (110). A D.C. to D.C. converter (140) is provided between the fuel cell stack and the D.C. bus (110)
摘要:
A query generator for generating a query for retrieving a desired set of data from a relational database is disclosed. The query generator is adapted to: a) receive an input query adapted to retrieve a superset of the desired set of data from the database; b) analyse a default filters table comprising one or more filter application criteria, each associated with a default filter condition that refers to data contained in the superset of data; and c) for each filter application criterion that is satisfied, modify the input query in accordance with the associated default filter condition to produce an output query adapted to retrieve the desired set of data only.
摘要:
Methods for creating computer-readable image files having annotation data, e.g., one or more audio annotations, embedded therein are provided. The method may include receiving an image file having image data therein, receiving annotation data, e.g., one or more audio annotations, relating to the image data, and embedding the annotation data into the image file to create a modified image file. Computer-readable media having stored thereon a data structure which includes a first portion containing data representing an image and a second portion containing data representing annotation information relating to the image, wherein the first portion is embedded in the second portion, are also provided. Still further, a computer-readable image file having image data and annotation data relating to the image data is also provided.
