摘要:
The present invention relates to compositions and a process in the field of self-cleaning system using digestive proteins. One composition includes a substrate, a digestive protein capable of decomposing a stain molecule, and a link moiety bound to both said digestive protein and said substrate. An alternative composition includes a digestive protein capable of decomposing a stain molecule and a coating substrate wherein said digestive protein may be dispersed in said coating substrate. The process claim includes binding a substrate to a surface and forming a linker moiety between a digestive protein and said substrate.
摘要:
Disclosed herein are systems and methods that are directed to alleviating the hidden node problem occurring in wireless systems by using the simultaneous transmission and reception (STR) capability without increasing the medium access layer (MAC) overhead. Accordingly, a receiving device receiving a data packet from a transmitting device can simultaneously transmit a data packet, called a STR Clear to Send (CTS). This STR-CTS can create a guard zone around the receiving device to avoid collisions from unwanted transmissions from secondary devices, e.g., neighboring STAs and/or APs. In various embodiments, the STR-CTS packet transmitted by the receiving device can be decodable by legacy devices, e.g. legacy STAs and APs, as well as next generation devices, for example, those employing unlicensed technologies such as LAA.

The invention provides high enzyme loading nanofibers and processes utilized in their fabrication, the nanofibers suitable for use as a new class of highly sensitive and stable biosensors capable of monitoring glucose at low levels. The biosensors, comprising nanofiber enzyme materials fabricated from organic solvent-based polymer-enzyme systems, can be used effectively in non-invasive transdermal biosensing applications.

Disclosed are a polymer solar cell and a preparation method thereof. The preparation method comprises: successively preparing on a clean glass substrate (1), a cathode (2), an electronic buffer layer (3) and an active layer (4) by the steps of dissolving poly(3,4-ethylenedioxythiophene) and polymerized p-styrene sulphonic acid, dissolving zinc oxide into acetic acid to obtain a zinc oxide solution, mixing the zinc oxide solution with the solution of poly(3,4-ethylenedioxythiophene) and polymerized p-styrene sulphonic acid to obtain a mixed solution, spin-coating the mixed solution on the active layer (4) and then by drying to obtain the anode (5), and finally obtain the polymer solar cell.
摘要:
A computer-implemented method of sorting electronic messages can include identifying at least one recipient of an electronic message and retrieving a classification scheme of the recipient. An identifier can be included within the electronic message. The identifier can specify a tag selected from the classification scheme of the recipient. The electronic message, including the identifier specifying the selected tag, can be sent.
摘要:
A mobile gateway device collects identities of a first set of radio nodes which are within one hop of the mobile gateway; and checks at least the collected identities against a first table and a second table. The first table lists node identities and corresponding data validity timers. The second table lists node identities and no corresponding data validity timers. From the checking the device selects a group of radio nodes to activate for collecting and reporting data. The device determines parent child relations among the radio nodes, which are sensor nodes of a wireless sensing network in an embodiment, and uses the list to activate only those nodes for which it does not have valid data to sense new data and transmit their sensing results.
