Effect of HIT Components on the Development of Breast Cancer Cells

open access: yesLife, 2021
Cancer cells circulating in blood vessels activate platelets, forming a cancer cell encircling platelet cloak which facilitates cancer metastasis. Heparin (H) is frequently used as an anticoagulant in cancer patients but up to 5% of patients have a side ...

Reconstructing Geometrical Models of Indoor Environments Based on Point Clouds

open access: yesRemote Sensing, 2023
In this paper, we present a workflow that combines supervised and unsupervised methods for the reconstruction of geometric models with architectural information from unordered 3D data. Our method uses a downsampling strategy to enrich features to provide

Investigation of Gasochromic Rhodium Complexes Regarding Their Reactivity towards CO

open access: yesProceedings, 2017
The detection of the toxic gas carbon monoxide (CO) in the low ppm range is required in different applications. We present a study of the reactivity of different gasochromic rhodium complexes towards the toxic gas carbon monoxide (CO).

On-Chip Temperature Compensation for Thermal Impedance Sensors

open access: yesProceedings, 2018
Electrical impedance spectroscopy is a widespread characterization method for solids or fluids in industrial applications. We here report on its thermal equivalent, the “thermal impedance spectroscopy”, improved by using a temperature compensation method
