摘要:
Disclosed is a general methodology to create nano fibers of therapeutic molecules that have a dual role, as both the delivery vehicle and the drug itself. It is shown that with proper molecular design, the integration of enzymatic reaction and self-assembly provides a powerful method to create molecular hydrogels of clinically-used therapeutics without compromising their bioactivities. In addition, the results disclosed herein demonstrate enzyme-instructed self-assembly as a facile strategy for generating the supramolecular hydrogels of molecules that inherently have poor solubility in water. For example, by covalently connecting paclitaxel with a motif that is prone to self-assemble, a hydrogel of paclitaxel can be formed without compromising the activity of the paclitaxel.

Web page optimization systems and methods are disclosed herein. In one implementation, a number of master pages and page layouts used to generate the web pages are defined. A number of channels are then defined to be associated with certain ones of the master pages and the page layouts. User device generating the request, a browser used to generate the request, and other suitable components of a user agent string in a web page request is then identified. A web page is rendered in response to the identified components of the user agent string using the master page and the page layout associated with a channel identified by such components of the web page request.

A phase shift keying transmitter circuit that includes: a variable frequency conversion stage adapted to receive a first data signal, wherein the variable frequency conversion stage comprises a plurality of frequency modulating elements, wherein the first data signal controls the number of the plurality of frequency modulating elements that are operated so as to control an operating frequency of the variable frequency conversion stage; and an output stage configured to switch between one of two possible outputs, the signals provided by one of the two possible outputs having an opposite polarity to the other, wherein the output stage is configured to receive a second data signal to control the switching between the two possible outputs, wherein the output stage is coupled to the variable frequency conversion stage and wherein the switching between the two possible outputs changes the phase of a signal from the variable frequency conversion stage by 180°.

Embodiments of the present invention provide techniques for tracking the lifecycles of client-side browser windows in the context of a web application. In one set of embodiments, a server component of a web application can receive a notification that an application page in a first window has been unloaded/destroyed. In response, the server component can associate the first window with an expiration time and add the first window to an “expiration” list of windows that are potentially inactive. If a request is received by the server component from the first window while the first window is in the expiration list, the server component can identify the first window as active and remove it from the list. If a request is received by the server component from a second window after the expiration time associated with the first window, the server component can identify the first window as inactive and free all resources for the first window.
摘要:
A client computer has a master window and at least one slave window. The client computer receives streaming data at the master window. The master window includes a list of slave windows and the data includes an envelope that has a destination window identifier. The master window determines a destination window that corresponds to the window identifier. The master window dispatches the data to a slave window if the destination window is not the master window. Otherwise, the master window streams the data to the destination within the master window.

摘要:
A method for selective regulation of a background surface property of an array by adding a first building block molecule capable of forming a nucleotide or an amino acid bond on the spot and the background surface, adding a first protecting group to protect the first building block molecule on the spot and adding a second protecting group to protect the first building block molecule on the background surface, wherein the first protecting group is different from the second protecting group is disclosed. An array comprising a substrate comprising a substrate surface comprising a branched molecule wherein one end of branched molecule is attached to the substrate surface and the other end has many branches, further comprising a spacer in the branches to spread the branches and fluorophore molecules attached to the branches such that an average spacing between two fluorophore molecules is greater than 10 nm is disclosed.

Fluorinated pentacene derivatives, for example, the novel compounds tetradecafluoropentacene, 5,6,7,12,13,14-hexafluoropentacene, 5,7,12,14-tetrafluoropentacene, and 6,13-difluoropentacene, and intermediates therefor are provided. And a method of producing fluorinated pentacene derivatives and intermediates therefor is also provided. Pentacene derivatives fluorinated at desired positions of the pentacene skeleton are obtained by introducing the oxo group, hydroxyl group, or alkoxyl group into the pentacene skeleton followed by fluorination with sulfur tetrafluoride and partial defluorination using a reducing agent.
