Determination of the focus point for measurements of the modulation transfer function MTF [PDF]

EPJ Web of Conferences
At PTB, a multi camera MTF measurement setup is developed for the traceable determination of the modulation transfer function (MTF) of objectives. In recent works the MTF of a reference objective is determined within the image field in an angular range ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

Zoom Auxiliary Imaging Lens Design for a Modulation Transfer Function Test System

Photonics
In this paper, we propose a zoom auxiliary imaging lens based on the four-component mechanical zoom method for a modulation transfer function (MTF) test system. The auxiliary imaging lenses of the current MTF test system typically use fixed-focus optical

Thermal Modulation Transfer Function (TMTF)

Proceedings of the 2000 International Conference on Quantitative InfraRed Thermography, 2000
The TMTF is a tool for thermal NDE (pulsed thermography). It gives a synthetic view of the thermal contrast degradation that is inherent with a reduction of the defect size. It was built, like the MTF in visual or IR imaging, by using a target with a periodic pattern. The TMTF was numerically simulated with a model having a cluster of parallel slots on

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

Molecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...
