Methods are provided in which a sterol-depleting agent such as β-cyclodextrin (βCD), is used to modulate signaling by a differentiation signaling protein such as Hedgehog protein or a BMP in vitro. As illustrated herein, the use of βCD in conjunction with Sonic Hedgehog N-terminal peptide (ShhN) causes substantially all of the cells in neural plate explants to differentiate as neurons, such as motor neurons. Also provided are cell therapy methods and screening methods that rely on the modulation of signaling of a differentiation signaling protein such as Hedgehog, by a sterol-depleting agent such as βCD.

A computer program product is tangibly embodied on a computer-readable medium and includes executable code that, when executed, is configured to cause a data processing apparatus to display multiple objects in a three dimensional (3D) representation, where the multiple objects are visual representations of real objects, and display a subset of the objects and associated metadata in a shaped lens that is movable within the 3D representation in all three axes, where the subset of the objects displayed within the shaped lens are sized larger than the objects outside of the shaped lens.

An apparatus in one embodiment handles service requests over a network, wherein the network utilizes a protocol. In this aspect, the apparatus includes: a network subsystem for receiving and transmitting network service requests using the network protocol; and a service subsystem, coupled to the network subsystem, for satisfying the network service requests. At least one of the network subsystem and the service subsystem is hardware-implemented; the other of the network subsystem and the service subsystem may optionally be hardware-accelerated. A variety of related embodiments are also provided, including file servers and web servers.

A file system adapter card that may be plugged into a host computer system for providing hardware-based file system accesses outside the purview of a host operating system running on the host computer system. The file system adapter card includes a hardware-implemented or hardware-accelerated file service subsystem and a computer bus that permits a host computer system to communicate directly with the file service subsystem for providing file service requests and receiving file service responses. The file service subsystem includes dedicated hardware that operates outside the immediate control of a host operating system, including specialized circuitry for performing at least one major subsystem function.

Personalized searching including providing in a search portal a personal search term list; receiving from a user a navigation identification message; and inserting index records in a personalized search index. Inserting index records in a personalized search index typically comprises retrieving a document from a navigation location and indexing the navigation location and keywords from the personal search term list that occur in the retrieved document. A navigation identification message may comprise a search keyword and inserting index records in a personalized search index may include indexing the search keyword with the navigation location in the personalized search index. Embodiments typically include creating and transmitting to users, in dependence upon the personalized search index, search criteria, and user identification, responses to search query messages.
摘要:
A hydraulic clutch actuation system having a hydraulic clutch control device which includes at least one clutch master cylinder that communicates via a pressure-medium line with a clutch slave cylinder used for actuating a clutch device, the pressure prevailing in the pressure-medium line being relievable via at least one emergency release valve device to permit disengagement of the clutch device in an emergency situation. The hydraulic clutch actuation system is distinguished in that the emergency release valve device has a seal-carrier device for a sealing element which is movable in response to an electromagnet out of an open position, in which a pressure-medium inlet is open, into a closed position in which the sealing element seals the pressure-medium inlet.
摘要:
An improved multi-layered integrated RF/IF circuit board has been disclosed. The board is fabricated beginning with a center layer of material. In a first preferred embodiment, the center layer is a rigid core material. In a second preferred embodiment, the center layer is a pliable non-conductive material. For every layer added to the upper surface of the stack-up structure of the board, a corresponding layer of the same material is added to the lower surface of the stack-up structure. Thus, during the lamination process, both the upper and lower surfaces are primarily soft, pliable non-conductive material. These non-conductive layers absorb any stresses introduced during the lamination process. Thus, when cooled, the board has large area flatness. Standard manufacturing processes can be used for each individual step in the fabrication of the board. Therefore, a multi-layered integrated RF/IF circuit board in accordance with the present invention can be fabricated inexpensively.
