Individual probes on micro-arrays are re-scaled and corrected with a set of probe dependent coefficients derived from genomic-DNA hybridization signals. A dynamic range for gDNA binding is determined by measuring a concentration signal curve. Signals for each probe are measured during multiple hybridizations within a linear range. Concentration insensitive probes are then found for two sets of experiments. Probes are discarded based on a threshold compared to their standard deviation divided by their average in each set. The correction coefficients are used to calculate a corrected intensity for each probe. Probes having high uncertainty (0.5 in one embodiment) are discarded. A weighting factor for each probe is determined along with an uncertainty factor. Finally, a call for each gene is made, such as absent, marginal or present.

Receiver based method for de-spreading of spread spectrum signal

A spread spectrum receiver whose de-spreading process based on transformed spreading codes is provided. Instead of de-spreading with original spreading codes, this approach de-spreads received signal with the spreading codes transformed from the original codes in order to eliminate the negative impact of system impairments such as frequency offset to a spread spectrum receiver.

An approach is given to cancel unwanted side effects relating the transformed spreading codes. The approaches are very effective for spread spectrum system based on frequency modulation scheme such as MSK. For this kind of system, the frequency offset translates to DC offset after the transformation and the DC offset can be cancel since the DC property of the transformed spreading code is known in advance.

By providing the baffle structure, the present disclosure can cut off the flow path of the short-circuit flow and the radially centripetal moving gas flow such as the centripetal flow in the particle spiral band area, weaken the short-circuit flow, the inner vortex flow and the precessing vortex core, thus improving separation efficiency of fine particles with particle diameters of 1 μm to 10 μm.

Rf amplifier circuit and method of operating thereof

Shared receiver and transmitter filter

The present invention provides methods and apparatuses for a shared filter transceiving system. A shared filter transceiving system having a capacitor bank to adjust the time constant of the shared filter comprises a first input configured to receive a first signal. The capacitor bank is coupled to the first input having a plurality of selectable capacitors including a reference capacitor. A second input is coupled to the capacitor bank configured to receive a second signal. A configurable switch is coupled to the capacitor bank configured to couple a first selectable capacitor with the reference capacitor when the first input is active and couple a second selectable capacitor with the second reference capacitor when the second input is active. The second selectable capacitor is a predetermined offset value of the first selectable capacitor.

The application provides T cell gene expression signatures that can be used to predict T cell therapy outcomes.

Fractional decimation filter using oversampled data

A decimator is provided that selectively varies the output sampling rate of an integer decimating device, such that the average output sampling rate corresponds to a desired output sampling rate. The output sampling rate varies such that an output sample is provided selectively after N input samples, or after N+1 input samples, to provide an output-to-input sampling ratio that is between N and N+1. This process introduces phase jitter as the sampling frequency varies between 1/N and 1/(N+1), but if the oversampling rate is high, and therefore N is high, as is typical of many applications that employ oversampling, the relative magnitude of the phase jitter is slight. A fractional accumulator is used to control whether the output occurs after N or N+1 input cycles, and is clocked by the input sampling clock, thereby minimizing the complexity of the embodiment.

Continuous vacuum production method for laminated glass

The present disclosure provides a production method for laminated glass. The production method includes the following steps: loading laminated glass into a vacuum inlet chamber, evacuating to a first vacuum pressure, and transferring the glass at a high speed; transferring the glass to a vacuum inlet buffer chamber, and evacuating to a second vacuum pressure; transferring the glass to a vacuum inlet transfer chamber, reducing the transfer speed for low-speed transfer, and evacuating to a third vacuum pressure; transferring the glass to a vacuum heating chamber, maintaining a third vacuum pressure, and heating; transferring the glass to a vacuum cooling chamber, maintaining a third vacuum pressure, and cooling; transferring the glass to a vacuum outlet transfer chamber, maintaining a third vacuum pressure, and increasing the transfer speed for high-speed transfer; transferring the glass to a vacuum outlet buffer chamber, and dropping a vacuum pressure to a second vacuum pressure; transferring the glass to a vacuum outlet chamber, dropping a vacuum pressure to a first vacuum pressure, and outputting finished laminated glass. The laminated glass produced by the present disclosure has a high yield and low energy consumption.
