Molecular Oncology, EarlyView.Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Non-linear viscoelastic characterization of perfluroelastomer raw rubber
Hecheng xiangjiao gongyeLarge-amplitude oscillatory shear (LAOS) tests were carried out on 1055 B and 2160 B perfluroelastomer raw rubber. The structural differences were explored by analyzing their rheological behavior.

Noise Reduction by Barriers [PDF]
The Journal of the Acoustical Society of America, 1973 A literature review is prepared to summarize the present state of knowledge concerning the field performance of barriers, with particular reference to screen-type barriers on finite impedance ground, to barriers of finite thickness, to right-angle wedges, to multiple barriers, and to effects of wind.

Molecular Oncology, EarlyView.This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
