A current gain β of 23 is demonstrated from a small-area NpN GaAs-based double heterojunction bipolar transistor (HBT) using a low band-gap InGaAsN material (lattice matched to GaAs with an energy band gap EG of 1.2 eV) as the base layer.
Results indicate that all melanoma lesions are correctly classified, using a low number of bands, reaching 100% sensitivity and 72% specificity when considering nine (out of a total of 55) spectral bands.
Using a low-, high-, band-pass, or other filters inserted prior to the receiving detector (i.e. CMOS array sensor, the most common camera used for smartphones) increases selectivity of emitted fluorescent light.
Also, when the MS is close to the BS, the high speed transmission from the MS to the BS can also be achieved without taking any additional licensed frequency band by using a low transmission power.
Using a low grade detergent.
Beat slowly or using a low speed.
The focus of this study is on investigating the feasibility of soil moisture estimation based on GPS L1 band interference signals which can be readily captured using a low-cost off-the-shelf L1-band GPS receiver.
Compared with the architecture using a low-pass sigma-delta modulator, this band-pass solution uses a much lower sampling frequency for the sigma-delta modulator and thus reduces the requirement for frequency response of the detection interface and control electronics.
For the treatment-frequency decomposition, given a relatively narrow frequency band, we used a low pass filter with a steep cut-off frequency to gain the optimal balance between removing ringing artifact and approximating desired frequency response [ 48].
Use a low flocculating yeast strain.
