A New Algorithm for Local Background Suppression in Hyperspectral Target Detection

, 2010
This paper deals with target detection in hyperspectral images based on local background suppression. Global approaches to background subspace estimation and suppression may be ineffective for target detection purposes. In fact, they tend to overestimate

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

An Effective Method for Small Targets Detection in Synthetic Aperture Radar Images Under Complex Background

IEEE Access, 2022
Synthetic Aperture Radar (SAR) is a useful tool in marine surveillance. Small targets detection in SAR images especially in nearshore area is a difficult issue. Due to the complex background, there exist a lot of false targets.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Transverse energy dependence of J/[psi] suppression on heavy ion collisions [PDF]

, 1988
Karsch F, Petronzio R. Transverse energy dependence of J/[psi] suppression on heavy ion collisions. Physics Letters, B. 1988;212(2):255-258.We discuss the transverse energy and the nuclear size dependence of J/[psi] suppression in heavy ion collisions ...

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Boosting background suppression in the NEXT experiment through Richardson-Lucy deconvolution

Journal of High Energy Physics, 2021
Next-generation neutrinoless double beta decay experiments aim for half-life sensitivities of ∼ 1027 yr, requiring suppressing backgrounds to < 1 count/tonne/yr.

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer

Molecular Oncology, EarlyView.
New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.
