A High-Precision Acquisition Algorithm for DSSS Signals in Low CNR Scenarios Using 2-D Parallel Fuzzy Logic Control

IEEE Access
This paper proposes a fast, high-precision acquisition algorithm based on two-dimensional parallel fuzzy logic (FL) control for direct sequence spread spectrum signals in Lunar-Earth telemetry, tracking, and command (TT&C) scenarios with high ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Immigrant Job Search in the UK [PDF]

Most immigrant groups in the UK experience higher unemployment rates than otherwise similar UK born whites. Empirical research to date has attributed this finding to discrimination, lack of English Language fluency and the (non-) transferability of ...

Quantitative proteomic analysis reveals different characteristics of bladder cancer cells after exposure to bisphenol A

FEBS Open Bio, EarlyView.
Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Best hypotheses search on iso-energy-grid for initial orbit determination and track association

, 2013
Debris populating the geostationary orbit is mainly observed by ground-based optical telescopes. Short measurement arcs, known as tracklets, provide line-of-sight information along with the associated rates of change.

Boosting Performance of SVM in Koi Classification Using Direct Methods-Based Optimization

JOIV: International Journal on Informatics Visualization
Many koi fish enthusiasts keep or buy them just for their attractive colors without knowing what type of koi fish they are. The manual classification of koi fish species is still frequently incorrect.

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.
