An Improved Optimized Selection Algorithm of Chaotic Spread Spectrum Sequence [PDF]
Jisuanji gongcheng, 2016 Because of the high initial value sensitivity,complexity and strong correlation,the chaotic sequence is suitable to be used as spread spectrum sequence.But in practice,the chaotic sequences should be optimized selection.In order to achieve more chaotic ...

The Simulation Study of the Spread-Spectrum System [PDF]
Proceedings of the 2015 4th International Conference on Computer, Mechatronics, Control and Electronic Engineering, 2015 Spread-spectrum technology produces a transmitted spectrum much wider than the minimum bandwidth required and links as a means of overcoming intentional jamming. In this paper, we provide a brief outline of the theory of the spread-spectrum technique. Then we apply this technique to FSK system and give simulation results.

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Comparative analysis between chaotic sequence and PN sequence in spread spectrum system
Journal of Measurement Science and Instrumentation, 2016 This paper introduces two kinds of sequences used in spread spectrum communication system:pseudo-noise（PN）sequence generated by linear feedback shift register（LFSR）,such as m-sequence and Gold sequence,and the chaotic sequence generated by the ...

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Chirp Spread Spectrum Transceiver Design and Implementation for Real Time Locating System
International Journal of Distributed Sensor Networks, 2015 A chirp spread spectrum (CSS) transceiver architecture for IEEE 802.15.4a is proposed and implemented. In the transmitter, the size of the read-only memory that stores CSS signal samples for the chirp modulator is reduced by removing duplicate samples ...

Novel UWB and Spread Spectrum System Using Time Compression and Overlap-Add Techniques
IEEE Access, 2014 We present a UWB and spread spectrum communications method based on the idea of time compression where a sampled message signal is transmitted at a higher sampling rate.

Molecular Oncology, EarlyView.In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...
