Abstract: The present disclosure discloses a gold/quantum dot nanoprobe for detecting active ricin in a complex matrix and application thereof. The gold/quantum dot nanoprobe is a nanoprobe formed by utilizing gold nanoparticles and quantum dots, which are modified by single strand oligodeoxynucleotides (ssODN), to form double strand oligodeoxynucleotides in a base pairing hybridizing mode and assembling the gold nanoparticles and the quantum dots into a core-satellite structure. According to the present disclosure, the gold/quantum dot nanoprobe is used for detecting the active ricin, has a limit of detection of 7.46 ng/mL, is high in accuracy and good in reliability, and does not require large-scale equipment and complex operations. In order to further eliminate the false positive result, the present disclosure further provides a method for enriching ricin in a complex sample by utilizing magnetic beads.

Abstract: A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties. One example may comprise one or more of creating one or more control commands configured to control one or more smart devices, signing the one or more control commands via a key maintained by an entity creating the control commands, broadcasting the one or more control commands to the one or more smart devices, and storing the one or more control commands in a blockchain.

Abstract: Machine logic (for example, software) for protecting sensitive and confidential user data and sending the protected user data to an authorized third party for predictive analytics purposes. The machine logic rules perform linear transformation operations on the sensitive and confidential user data in order to obscure the underlying data before it is sent to an authorized third party for performing predictive analysis of the underlying data. After performing predictive analysis on the obscured data by the authorized third party, the owner of the sensitive and confidential data takes a consequential action (that is, the owner of the data makes a business-related decision) based on the prediction.

Abstract: A computer-implemented data transmission method and system are provided. A first transformed password (PWD) is acquired from the first node, wherein the first transformed PWD is derived from an original PWD. An encrypted message is acquired from the first node, the encrypted message being encrypted with a public key of the first node. A private key of the first node is recovered according to the first transformed PWD, the private key having been encrypted with the first transformed PWD and stored in the second node in advance. The encrypted message is decrypted with the recovered private key to obtain a decrypted message for processing.

Abstract: A freeform DOE for use in an optical transmitter and a method of designing and manufacturing the DOE are provided. The freeform DOE is capable of achieving the same, or nearly the same, functionality as that of a glass DOE, but has a design that has been transformed to make the surface profile of the DOE compatible with a molding process that can be used to manufacture the DOE with high quality at low costs. The method of designing and manufacturing the DOE includes preselecting a CGH that will obtain a target freeform DOE design, using a preselected smoothing function to smooth the surface profile of the target freeform DOE design to transform the design into a DOE design that is compatible with a molding process, and using a fabrication process to manufacture a freeform DOE that is based on the transformed DOE design.
