摘要:
A method for reversibly, or irreversibly, altering the permeability of cells, tissues or other biological barriers, to molecules to be transported into or through these materials, through the application of acoustic energy, is provided. The acoustic energy is applied indirectly to the cells or tissue whose permeability is to be altered, at a frequency and intensity appropriate to alter the permeability to achieve the desired effect, such as the transport of endogenous or exogenous molecules and/or fluid, for drug delivery, measurement of analyte, removal of fluid, alteration of cell or tissue viability or alteration of structure of materials. In the preferred embodiment, the method includes applying the ultrasound in combination with devices for monitoring and/or implementing feedback controls.

The present invention proposes a method for scheduling resource in a packet network and a network element for exchanging signaling with user equipments, wherein user equipments communicate therebetween using the resource allocated by network elements, said communication comprises talk-spurt periods during which data packets are transmitted and silent periods during which silence descriptor packets are transmitted, said method for scheduling resource comprising: said network element allocates resource for said user equipments for communication; both said user equipment and said network element detect the presence of said silence descriptor packet, and said network element determines the optimized number of resource unit(s) to be allocated to said user equipment during the interval for transmitting said data packet, based on the coding rate of said user equipment, the selected modulation coding scheme and the valid transmission times; the network element starts timing and the user equipment stops using the allocated resource if a silence descriptor packet is detected; when the timing finishes or a request for allocating resource is received from the user equipment before the end of said timing, said network element allocates the determined optimized number of resource unit(s) to said user equipment, and said user equipment begins to use said determined optimized number of resource unit(s); said network element determines the end of the interval for transmitting said data packet by detecting the silence descriptor packet; and when both said user equipment and said network element detect a silence descriptor packet, said user equipment stops using said determined optimized number of resource unit(s), while said network element releases said determined optimized number of resource unit(s).

This invention relates to virally-immortalized hepatocyte cell lines, which are derived from a normal primary human liver cell, have the ability to proliferate in a serum-free media, are nontumorigenic, and produce proteins. These cell lines can be used for toxicity testing of potential therapeutic drugs and chemical entities. The cell lines may also be used for the production of therapeutic plasma proteins.
摘要:
Assessing open circuit and short circuit defect levels in circuits implemented in state of the art ICs is difficult when using conventional test circuits, which are designed to assess continuity and isolation performance of simple structures based on individual design rules. Including circuit blocks from ICs in test circuits provides a more accurate assessment of defect levels expected in ICs using the circuit blocks. Open circuit defect levels may be assessed using continuity chains formed by serially linking continuity paths in the circuit blocks. Short circuit defect levels may be assessed by using parallel isolation test structures formed by linking isolated conductive elements in parallel to buses. Forming isolation connections on a high metal level enables location of shorted elements using voltage contrast on partially deprocessed or partially fabricated test circuits.

An equalizer consistent with certain embodiments has a differential analog tapped delay line made of a plurality of N series connected analog delay cells. Each cell has a pair of differential inputs and a pair of differential outputs. The delay line receives an input signal to be equalized. The differential input pair of the nth cell is connected to the differential output pair of the (n−1)th cell such that current is mirrored from the output pair to the input pair to form N−1 differential taps. Each one of N−1 differential input multiplying digital to analog converters (MDAC) is connected at its differential input at each differential tap, with each MDAC multiplying an analog signal at its input by a digital weighting factor to produce an output at a differential output. A differential slicer receives a sum of the differential outputs from each of the MDACs and produces an equalized output. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

A read activity detector circuit for use in a random access memory array includes a plurality of synchronizer circuits operative to receive a plurality of respective reference clock signals having a frequency that is substantially the same as a core reference clock and having different phases relative to one another. Each of the synchronizer circuits, in response to a first control signal presented thereto, generates an output signal having a rising edge or a falling edge which is substantially aligned to a rising edge or a falling edge of the reference clock signal corresponding thereto. The activity detector circuit further includes a controller operative to receive the respective output signals from the plurality of synchronizer circuits and to generate an output signal as a function thereof which is indicative of data to be read from the random access memory array.
