3D Reconstruction with Uncalibrated Cameras Using the Six-Line Conic Variety

open access: yes, 2008
We present new algorithms for the recovery of the Euclidean structure from a projective calibration of a set of cameras with square pixels but otherwise arbitrarily varying intrinsic and extrinsic parameters.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

open access: yesMolecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Robust 3D-Mapping with Time-of-Flight Cameras

open access: yes, 2009
Time-of-Flight cameras constitute a smart and fast technology for 3D perception but lack in measurement precision and robustness. We present a comprehensive approach for 3D environment mapping based on this technology.

Secured Perimeter with Electromagnetic Detection and Tracking with Drone Embedded and Static Cameras

open access: yesSensors, 2021
Perimeter detection systems detect intruders penetrating protected areas, but modern solutions require the combination of smart detectors, information networks and controlling software to reduce false alarms and extend detection range.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

open access: yesMolecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Upper-Secondary Students’ Use of Infrared Cameras in the Study of Animals’ Temperature

open access: yes, 2022
The aim of this study was to provide insight into how students may use infrared cameras in inquiry-based investigation of animals’ temperature. Upper-secondary students at the vocational Natural Resource Use programme in Sweden were given the open-ended ...

An Indoor Positioning Approach Based on Fusion of Cameras and Infrared Sensors

open access: yesSensors, 2019
A method for infrared and cameras sensor fusion, applied to indoor positioning in intelligent spaces, is proposed in this work. The fused position is obtained with a maximum likelihood estimator from infrared and camera independent observations. Specific

MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Cameras

open access: yes, 2023
This chapter takes up the literary reverberations of two types of photography – still and moving – in the nineteenth and twentieth centuries. The invention and popularization of still photography in the nineteenth century posed a challenge to all ...
