Suppression of co-channel interference in NGSO constellation system with interference alignment

open access: yesTongxin xuebao, 2021
Aiming at the problem that in the current space, non-geostationary satellite orbit (NGSO) constellation systems were increasing day by day, there are more and more satellite networks nearby orbiting using the same frequency band, and the problem of co ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Narrowband Suppressive Interference Suppression for UAV-Borne SAR Based on TSA-ISN

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In complex electromagnetic environments, uncrewed aerial vehicle (UAV)-borne synthetic aperture radar systems are highly susceptible to suppressive interference, which severely degrades imaging quality by obscuring target echoes.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Suppression and Interference Control in Memory Retrieval [PDF]

open access: yes, 2019
Resolving interference from competing information is a critical factor in memory retrieval. This thesis investigated suppression as the inhibitory mechanism required to select target information among competitors, by examining the effect of aging and the

Review of Synthetic Aperture Radar Interference Suppression

open access: yesLeida xuebao, 2020
Synthetic Aperture Radar (SAR) has attracted much attention in the recent decades owing to its allweather and high-resolution working mode. As an active radar system, the high-resolution imaging process of SAR systems is affected by different types of ...

Successive DF relaying: MS-DIS aided interference suppression and three-stage concatenated architecture design

open access: yes, 2012
Conventional single-relay aided two-phase cooperative networks employing coherent detection algorithms incur a significant 50% throughput loss. Furthermore, it is unrealistic to expect that in addition to the task of relaying, the relay-station would ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular 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.
