An iALM-ICA-based Anti-Jamming DS-CDMA Receiver for LMS Systems

open access: yes, 2018
We consider a land mobile satellite communication system using spread spectrum techniques where the uplink is exposed to MT jamming attacks, and the downlink is corrupted by multi-path fading channels. We proposes an anti-jamming receiver, which exploits

Multi-Stage Complex Notch Filtering for Interference Detection and Mitigation to Improve the Acquisition Performance of GPS [PDF]

open access: yes, 2018
Continuous Wave Interferences (CWIs) can degrade the accuracy of a Global Positioning System (GPS) receiver and moreover it can completely deteriorate receiver’s normal operation.

The Anti-Jamming Design Based on DSP System [PDF]

open access: yesProceedings of the 2nd International Conference on Computer Science and Electronics Engineering (ICCSEE 2013), 2013
This paper describes the sources of interference in the DSP system and its harm. The designs of both the hardware and the software anti-jamming technology are given respectively, and the purpose of the DSP system anti-jamming is realized.

Modeling and experimental study on drilling rig anti-jamming valve with BP neural network [PDF]

open access: yes, 2016
An effective anti-jamming system is significant in improving the working reliability of hydraulic drilling rigs. An anti-jamming valve is a core component of an anti-jamming system. A back-propagation (BP) neural network model was established for an anti-

Early metastasis is characterized by Gr1+ cell dysregulation and is inhibited by immunomodulatory nanoparticles

open access: yesMolecular Oncology, EarlyView.
Breast cancer metastasis is associated with myeloid cell dysregulation and the lung‐specific accumulation of tumor‐supportive Gr1+ cells. Gr1+ cells support metastasis, in part, through a CHI3L1‐mediated mechanism, which can be targeted and inhibited with cargo‐free, polymeric nanoparticles.

Anti-jamming in a fungal transport network

open access: yes, 2016
Congestion limits the efficiency of transport networks ranging from highways to the internet. Fungal hyphal networks are studied as an examples of optimal biological transport networks, but the scheduling and direction of traffic to avoid congestion has not been examined.
