A detector prototype based on MAPS (monolithic active pixel sensor) is under development for the upgrade of the BESIII inner tracker. Pixel detector ladders with low material budget and high chip position precision are being developed. Each ladder consists of ten MIMOSA28 chips thinned to 50 μm , a flex cable and a carbon fibre support. In order to...
High voltage CMOS pixel sensors will be or are proposed to be used in several particle physics experiments for particle tracking like Mu3e experiment. ATLASPIX3 is the first full reticle size monolithic HVCMOS sensor for construction of multi-chip modules. The specifications for the use case have been taken from ATLAS pixel upgrade in fifth layer w...

The nose represents the most common site for the presentation of cutaneous cancer, especially in sun-exposed areas: ala, dorsum, and tip. Even the smallest loss of substance can create aesthetic and psychosocial concerns for patients; therefore, surgeons who perform nasal reconstruction should be strictly confident with the pertinent surgical anato...
Autoimmune and multifocal atrophic gastritis (AG) are at risk for gastric neoplastic lesions. European guidelines recommend surveillance with high-quality endoscopy every 3 years. To prospectively investigate the occurrence of gastric neoplastic lesions at the 3-year follow-up in patients with autoimmune and multifocal AG. Longitudinal cohort study...
Experiment ALICE v CERN připravuje inovaci svého vnitřního dráhového detektoru. Tento detektor bude sestávat ze sedmi koncentrických vrstev křemíkových senzorů ALPIDE založených na technologii MAPS. S tímto projektem je spojena celá řada testovacích studií, kdy se sleduje odezva senzorů ALPIDE na částice ionizujícího záření. K testování radiační od...
LF-Monopix1 and TJ-Monopix1 are depleted monolithic active pixel sensors (DMAPS) in 150 nm LFoundry and 180 nm TowerJazz CMOS technologies respectively. They are designed for usage in high-rate and high-radiation environments such as the ATLAS Inner Tracker at the High-Luminosity Large Hadron Collider (HL-LHC). Both chips are read out using a colum...
With the advancement of high-precision radiotherapy and the increasing use of higher intensity beams, the risk to the patient increases should the radiotherapy machine malfunction. Hence more accurate treatment verification is required. In this paper we provide a solution for real-time monitoring of X-ray beams from radiotherapy linear accelerators...
Context: Dust plays an important role in shaping a galaxy’s spectral energy distribution (SED). It absorbs ultraviolet (UV) to near- infrared (NIR) radiation and re-emits this energy in the far-infrared (FIR). The FIR is essential to understand dust in galaxies. However, deep FIR observations require a space mission, none of which are still active ...
To be able to design indoor wayfinding systems that adhere better to the needs of the users, user perception on complexity needs to be examined and linked to user characteristics and decision point characteristics. To identify how these characteristics influence perception, an online survey is executed in which participants had to indicate how comp...
The last couple of years have seen the development of Depleted Monolithic Active Pixel Sensors (DMAPS) fabricated with a process modification to increase the radiation tolerance. Two large scale prototypes, Monopix with a column drain synchronous readout, and MALTA with a novel asynchronous architecture, have been fully tested and characterized bot...
