Investigation of applicability of alanine pellets and films for dosimetry of proton clinical beams
2015
Laser-driven proton has recently gained a great interest as an alternative to conventional and more expensive acceleration techniques. These ion beams have desirable qualities such as small source size, high luminosity and small emittance to be used in different physics fields. This is very promising specially for the future perspective of a new concept of hadrontherapy based on laser-based devices could be developed, replacing traditional accelerating machines. ELIMED (Medical Applications at Extreme Light Infrastructure) is a task-force originally born by an idea of ELI-Beams (Prague) and INFN-LNS (Italian Institute for Nuclear Physics of Catania) researchers. ELIMED main goal is to perfo…
How Idioms Are Recognized when Individuals Are “Thrown Off the Track”, “Off the Rack” or “Off the Path”: A Decision Time Experiment in Healthy Volunt…
2021
Figurative elements in language have their own particularities, including words that deviate from their generally accepted definition to amplify our language or to paraphrase an issue. It is still unclear how individuals process idioms that are figurative or ambiguous, especially when they additionally become distracted by modified idioms that are similar in appearance. In our study, 47 healthy adults (mean age of 27.3 years, SD = 2.9) participated in a decision time experiment to determine how participants recognize well-formed, genuine German idioms alongside certain idiom modifications. All participants were initially exposed to a prime on a screen. Then, they had to detect the target id…
The magnetohydrodynamic force experienced by spherical iron particles in liquid metal
2016
Abstract The paper contains a theoretical investigation of magnetohydrodynamic force experienced by iron particles (well-conducting and ferromagnetic) in well-conducting liquid. The investigation is performed by extending the Leenov and Kolin's theory to take into account the second-order effect. Therefore, the limits of the parent model are taken over to the present results. It is found that the effective conductivity of iron particles in liquid metal, which is important for practical application of the theoretically obtained force, is approximately equal to 1.5·106 S/m. The last result is obtained using a quasi-empirical approach – a comparison of experimental results with the results of …
The Death of the Subject in David Lynch's Lost Highway and Mulholland Drive
2003
International audience; Quel est le sujet de ces deux films qui ont suscité de nombreuses interrogations auprès du public lors de leur sortie, questions portant notamment sur la signification de la diégèse ? Nous avançons que ce n'est pas à ce niveau-là que l'on doit chercher le sens des films de Lynch. En fait, la mort du personnage comme sujet va de pair avec l'absence d'une histoire ; l'évolution du cinéma de Lynch montre que, si sujet il y a, c'est du côté du spectateur qui tient désormais le rôle de l'enquêteur que tenait les personnages dans les œuvres antérieures (Blue Velvet et la série Twin Peaks). Le sujet lynchien apparaît alors un véritable objet dans une composition qui se refl…
Major results from the first plasma campaign of the Wendelstein 7-X stellarator
2017
After completing the main construction phase of Wendelstein 7-X (W7-X) and successfully commissioning the device, first plasma operation started at the end of 2015. Integral commissioning of plasma start-up and operation using electron cyclotron resonance heating (ECRH) and an extensive set of plasma diagnostics have been completed, allowing initial physics studies during the first operational campaign. Both in helium and hydrogen, plasma breakdown was easily achieved. Gaining experience with plasma vessel conditioning, discharge lengths could be extended gradually. Eventually, discharges lasted up to 6 s, reaching an injected energy of 4 MJ, which is twice the limit originally agreed for t…
In Situ Generation of Transverse Magnetohydrodynamic Waves from Colliding Flows in the Solar Corona
2018
This research has received funding from the UK Science and Technology Facilities Council (Consolidated Grant ST/K000950/1) and the European Union Horizon 2020 Research and Innovation Programme (grant agreement No. 647214). V.M.N. acknowledges the support of the BK21 plus program through the National Research Foundation funded by the Ministry of Education of Korea. Transverse magnetohydrodynamic (MHD) waves permeate the solar atmosphere and are a candidate for coronal heating. However, the origin of these waves is still unclear. In this Letter, we analyze coordinated observations from Hinode/Solar Optical Telescope (SOT) and Interface Region Imaging Spectrograph (IRIS) of a prominence/corona…
Guided flows in coronal magnetic flux tubes
2018
There is evidence for coronal plasma flows to break down into fragments and to be laminar. We investigate this effect by modeling flows confined along magnetic channels. We consider a full MHD model of a solar atmosphere box with a dipole magnetic field. We compare the propagation of a cylindrical flow perfectly aligned to the field to that of another one with a slight misalignment. We assume a flow speed of 200 km/s, and an ambient magnetic field of 30 G. We find that while the aligned flow maintains its cylindrical symmetry while it travels along the magnetic tube, the misaligned one is rapidly squashed on one side, becoming laminar and eventually fragmented because of the interaction and…
MHD simulations of the in situ generation of kink and sausage waves in the solar corona by collision of dense plasma clumps
2019
Funding: This research has received funding from the UK Science and Technology Facilities Council (Consolidated Grant ST/K000950/1) and the European Union Horizon 2020 research and innovation programme (grant agreement No. 647214). P.A. acknowledges funding from his STFC Ernest Rutherford Fellowship (No. ST/R004285/1). This research was supported by the Research Council of Norway through its Centres of Excellence scheme, project number 262622. Context. Magnetohydrodynamic (MHD) waves are ubiquitous in the solar corona where the highly structured magnetic fields provide efficient wave guides for their propagation. While MHD waves have been observed originating from lower layers of the solar …
A happiness degree predictor using the conceptual data structure for deep learning architectures
2017
Abstract Background and Objective: Happiness is a universal fundamental human goal. Since the emergence of Positive Psychology, a major focus in psychological research has been to study the role of certain factors in the prediction of happiness. The conventional methodologies are based on linear relationships, such as the commonly used Multivariate Linear Regression (MLR), which may suffer from the lack of representative capacity to the varied psychological features. Using Deep Neural Networks (DNN), we define a Happiness Degree Predictor (H-DP) based on the answers to five psychometric standardized questionnaires. Methods: A Data-Structure driven architecture for DNNs (D-SDNN) is proposed …
Project driven orders managing practices in Polish construction industry
2014
Contemporary enterprises, focused on external business environment, define their strategic targets, with regard to the context of market and customer requirements. Their internal organization form should aim towards transformations, driven by global economic, political and social processes. This further involves rejecting of existing stereotypes, distribution of tasks and functions performance, as well as a possibility to adapt in response to environment variations, being well exemplified by project driven organizations. Management of individual single orders in enterprises with functional structures can be treated as “project driven orders” management. The orders may have manufacturing or …
