1,2,3,5-Tetramethyl-1H-pyrazol-2-ium triiodide

IUCrData, 2016
The title salt, C7H13N2+·I3−, was obtained unintentionally by methylation of 3,6-bis(3,5-dimethylpyrazol-1-yl)-1,2,4,5-tetrazine and subsequent fragmentation. The pyrazolium ring is almost planar (r.m.s.

An experimental method for the in-situ observation of eutectic growth patterns in bulk samples of transparent alloys

, 2007
We present an experimental method for the in-situ observation of directional-solidification fronts in bulk samples of transparent eutectic alloys. The growth front is observed obliquely in dark field through the liquid and a glass wall of the container ...

New Rotation Sets in a Family of Torus Homeomorphisms [PDF]

, 2015
We construct a family $\{\Phi_t\}_{t\in[0,1]}$ of homeomorphisms of the two-torus isotopic to the identity, for which all of the rotation sets $\rho(\Phi_t)$ can be described explicitly.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Statistical Deviations in Shoreline Detection Obtained with Direct and Remote Observations [PDF]

Journal of Marine Science and Engineering, 2019
Remote video imagery is widely used for shoreline detection, which plays a fundamental role in geomorphological studies and in risk assessment, but, up to now, few measurements of accuracy have been undertaken. In this paper, the comparison of video-based and GPS-derived shoreline measurements was performed on a sandy micro-tidal beach located in Italy

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

Molecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

Directional element based on the magnitude of positive-sequence superimposed impedance for active distribution networks

International Journal of Electrical Power & Energy Systems
The complex phase characteristics of inverter-interfaced distributed generators (IIDGs) during faults limit the effectiveness of traditional fault-component-based directional elements. In distribution networks with high-penetration, multi-point-connected

Direction-of-Arrival Estimation of Bottom-Mounted Horizontal Linear Array Based on the Weighted Phase Velocity

Journal of Marine Science and Engineering, 2023
The direction-of-arrival (DOA) estimation of an underwater bottom-mounted horizontal linear array (HLA) based on weighted phase velocity has been proposed in this paper.

BRDFs acquired by directional radiative measurements during EAGLE and AGRISAR [PDF]

, 2008
Radiation is the driving force for all processes and interactions between earth surface and atmosphere. The amount of measured radiation reflected by vegetation depends on its structure, the viewing angle and the solar angle. This angular dependence is

Stochastic transition model for pedestrian dynamics

, 2012
The proposed stochastic model for pedestrian dynamics is based on existing approaches using cellular automata, combined with substantial extensions, to compensate the deficiencies resulting of the discrete grid structure.
