Distributed Radiation Monitoring System for Linear Accelerators based on CAN Bus
Abstract—Gamma and neutron radiation is produced during the normal operation of linear accelerators like Free-Electron Laser in Hamburg (FLASH) or X-ray Free Electron Laser (X-FEL). Gamma radiation cause general degeneration of electronics devices and neutron fluence can be a reason of soft error in memories and microcontrollers. X-FEL accelerator will be built only in one tunnel, therefore most of electronic control systems will be placed in radiation environment. Exposing control systems to radiation may lead to many errors and unexpected failure of the whole accelerator system. Thus, the radiation monitoring system able to monitor radiation doses produced near controlling systems is crucial. Knowledge of produced radiation doses allows to detect errors caused by radiation, make plans of essential exchange of control systems and prevent accelerator from serious damages. The paper presents the project of radiation monitoring system able to monitor radiation environment in real time
Towards a comprehensive open source platform for management and analysis of High Content Screening data
As High Content Screening (HCS) has moved into the main stream for biological and pharmaceutical investigations, a lag of well integrated pipelines for automated acquisition, management and analysis of HCS results turns out to be a bottleneck for fully leveraging the wealth of information contained in a screen and moving to higher throughput. For many applications, monolithic pipelines can not deliver the flexibility and versatility needed. Laboratories and scientific service providers instead usually look into integrating components from both, the open source world and the commercial software world into best-of-breed data pipelines. In this article, we will present two open source components that can be used as flexible and powerful building blocks for such a pipeline
Reliability of an integrated ultrasound and stereophotogrammetric system for lower limb anatomical characterisation
Background. Lower extremity analysis for preoperative total knee and hip arthroplasty routines can increase surgery success rate
and hence reduce associated costs. Current tools are limited by being invasive, limited to supine analysis, or too expensive. This
study aimed to propose and validate a device, OrthoPilot®, based on the combined use of a stereophotogrammetric and
ultrasound system which can in vivo and noninvasively measure varus/valgus, flexion/extension, femur and tibia torsion, and
femur and tibia lengths. Methods. A phantom was measured by four operators to determine the resolution of the system.
Interoperator variability was measured on three operators who measured the above six variables on both legs of three subjects in
standing and supine positions. Intraoperator variability was assessed on data from three repeats from 9 subjects (18 legs).
Results. All 6 variables were reliably detected on a phantom, with a resolution of 1 mm and 0.5°
. Inter- and intraoperator
consistency was observed for varus/valgus, flexion/extension, and length measurements on the healthy subjects in standing and
supine positions (all ICC > 0.93). For torsion measurements, there was a considerable variation. Conclusion. The proposed
system, when used on healthy subjects, allowed reliable measurements of key parameters for preoperative procedures in both
supine and standing positions. Accuracy testing and further validation on patient populations will be the next step toward its
clinical adoption
Facilitated leaky scanning and atypical ribosome shunting direct downstream translation initiation on the tricistronic S1 mRNA of avian reovirus
The S1 mRNA of avian reovirus is functionally tricistronic, encoding three unrelated proteins, p10, p17 and σC, from three sequential, partially overlapping open reading frames (ORFs). The mechanism of translation initiation at the 3′-proximal σC ORF is currently unknown. Transient RNA transfections using Renilla luciferase reporter constructs revealed only a modest reduction in reporter expression upon optimization of either the p10 or p17 start sites. Insertion of multiple upstream AUG (uAUG) codons in a preferred start codon sequence context resulted in a substantial retention of downstream translation initiation on the S1 mRNA, but not on a heterologous mRNA. The S1 mRNA therefore facilitates leaky scanning to promote ribosome access to the σC start codon. Evidence also indicates that σC translation is mediated by a second scanning-independent mechanism capable of bypassing upstream ORFs. This alternate mechanism is cap-dependent and requires a sequence-dependent translation enhancer element that is complementary to 18S rRNA. Downstream translation initiation of the tricistronic S1 mRNA is therefore made possible by two alternate mechanisms, facilitated leaky scanning and an atypical form of ribosome shunting. This dual mechanism of downstream translation initiation ensures sufficient expression of the σC cell attachment protein that is essential for infectious progeny virus production
