Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

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.

GraphDuo: A Dual-Model Graph Processing Framework

IEEE Access, 2018
Algorithms for large-scale natural graph processing can be categorized into two types based on their value propagation behaviors: the unidirectional value propagation algorithms and the bidirectional value propagation algorithms. The graph computation in

Parallel Algorithms for Geometric Graph Problems [PDF]

, 2014
We give algorithms for geometric graph problems in the modern parallel models inspired by MapReduce. For example, for the Minimum Spanning Tree (MST) problem over a set of points in the two-dimensional space, our algorithm computes a $(1+\epsilon ...

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

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 ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

A geospatial skeleton framework for unveiling the 3D structure and dynamics of marine heatwaves from earth observation data

Geo-spatial Information Science
Understanding the multi-dimensional structure and evolution of geospatial phenomena is a fundamental challenge in Earth system science. Marine heatwaves (MHWs), as critical 4D spatio-temporal events in the ocean, exhibit complex vertical heterogeneity ...

Time and Frequency Resource Allocation Using Graph Theory in OFDMA Wireless Mesh Networks [PDF]

Journal of Systemics, Cybernetics and Informatics, 2014
A wireless network with a mesh topology works reliably and offers redundancy. In modern broadband wireless mesh networks that use MIMO and OFDMA techniques, the problems of time, frequency, and space resource allocations are different from a cellular ...

Non-Local Probes Do Not Help with Graph Problems

, 2015
This work bridges the gap between distributed and centralised models of computing in the context of sublinear-time graph algorithms. A priori, typical centralised models of computing (e.g., parallel decision trees or centralised local algorithms) seem to
