摘要:
The present invention provides a porous hollow silica micro- or nanoparticle with a polymer grafted thereon, wherein the polymer is selected from poly(methacrylic acid) and copolymers thereof. The polymer may be covalently linked to the silica particle via a bridging group. Provided is also a method of covalently coupling a poly(methacrylic acid) to a silica surface of a hollow silica particle. The method comprises contacting a silica surface of a hollow silica particle that carries amino functional or halogen functional groups with a poly(methacrylic acid) or a copolymer or a respective monomer thereof. The method further comprises allowing the carboxyl group of the monomer or the poly(methacrylic acid) and an amino functional group or a halogen functional group on the silica surface to undergo a coupling reaction, thereby covalently coupling the polymer to the silica surface.
摘要:
Described are a system and method for performing an automated quality assessment on a software program under test. A test automation system executes a test on a software program Data related to the test is automatically collected. The data includes first information determined by the test automation system in response to executing the test. The data further includes second information related to the test and received from a source other than the test automation system. The first information is analyzed. A quality assessment of the software program is generated from the analyzed first information and from the second information.

In a process for forming a hydrogel, a precursor crosslinkable through disulfide bonds for forming the hydrogel is provided in a solution. The precursor comprises a branched molecular structure, which comprises a plurality of branches. At least three of the branches each comprises a disulfide bond. The pH in the solution is adjusted to initiate thiol-disulfide exchange in the precursor, thus crosslinking the precursor through disulfide bonds formed by thiol-disulfide exchange. After the precursor is sufficiently crosslinked to form a hydrogel, the pH in the solution is adjusted to inhibit further thiol-disulfide exchange in the hydrogel. Further, a hydrogel matrix may comprise a polymer substantially crosslinked through disulfide bonds. The polymer may comprise a hydrophobic poly(amido amine) core and an amino-functionalized hydrophilic shell.

摘要:
In described embodiments, a transceiver includes an eye monitor, clock and data recovery, and adaptation modules. Data sampling clock phase and error clock phase determined from a data eye are decoupled in the transceiver during a sampling phase correction process. Decoupling these clock phases during the sampling phase correction process allows relative optimization of system equalization parameters without degradation of various adaptation algorithms. Such adaptation algorithms might be employed for received signal gain and equalization such as, for example, Decision Feedback Equalizer (DFE) adaptation. Deriving the data sampling clock and error clock phases from the same clock generation source and with independent clock control enables an iterative sampling phase correction process that allows for accelerated clock and data recovery (CDR) without disturbing the data eye shape.
摘要:
A portable communication device includes a housing body and a display. The housing body includes a hinge portion at one side. A block is formed at each side of the hinge portion. A display forms two knuckles at the other end. Each knuckle forms a plurality of teeth portions, and the hinge portion rotatably connects to the two knuckles. The blocks engage with the teeth portions allowing the display to hold any of a variety of selectable positions relative to the housing body.
