Dirakův kužel a pseudogapped hustota stavů v topologické polovině Heuslerovy sloučeniny YPtBi

2016

Topologické izolátory (Tis) jsou zajímavé materiály, které vykazují nebývalé vlastnosti. . Zde jsme prozkoumali sloučeniny YPtBi jako příklad ze třídy polovu-Heuslerových materiálů. Topological insulators (TIs) are exciting materials, which exhibit unprecedented properties, such as helical spinmomentum locking, which leads to large torques for magnetic switching and highly efficient spin current detection. Here we explore the compound YPtBi, an example from the class of half-Heusler materials, for which the typical band inversion of topological insulators was predicted. We prepared this material as thin films by conventional cosputtering from elementary targets. By in situ time-of-flight mo…

Anonymization as homeomorphic data space transformation for privacy-preserving deep learning

2021

Industry 4.0 is largely data-driven nowadays. Owners of the data, on the one hand, want to get added value from the data by using remote artificial intelligence tools as services, on the other hand, they concern on privacy of their data within external premises. Ideal solution for this challenge would be such anonymization of the data, which makes the data safe in remote servers and, at the same time, leaves the opportunity for the machine learning algorithms to capture useful patterns from the data. In this paper, we take the problem of supervised machine learning with deep feedforward neural nets and provide an anonymization algorithm (based on the homeomorphic data space transformation),…

Polyphenols Epigallocatechin Gallate and Resveratrol, and Polyphenol-Functionalized Nanoparticles Prevent Enterovirus Infection through Clustering an…

2021

To efficiently lower virus infectivity and combat virus epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) and Resveratrol (RES), and polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited the infectivity of high doses of enteroviruses (107 PFU/mL). Sucrose gradient separation of radiolabeled viruses, dynamic light scattering, transmission electron microscopic imaging and an in-house developed real-time fluorescence assay revealed that polyphenols prevented infection mainly through clustering of…

Humor and Disobedience : Understanding Controversial Humor

2016

In this article, I analyze controversial humor and argue that the concept of disobedience is of central importance when evaluating, for instance, harsh or potentially hurtful jokes. Following social critic Erich Fromm (1900– 1980) I claim that disobedience is a dialectic concept: that is, it includes the possibilities both to affirm and to reject. This observation connects humor to other values, and pivotal is how humor is related to the question of what it means to be a human being. Through this insight, I argue that controversial humor may shock and be offensive, or it can be amusing and even have a cathartic effect. In the end, in evaluating humor it is necessary to analyze the values be…

Les sarcophages mérovingiens en trachyte. Des carrières aux lieux d'enfouissement (Massif central)

2018

A multi-disciplinary team is currently working on trachyte, a volcanic rock from the Chaîne des Puys (French massif central), within a research program supported by the French ministry of Culture. Although it has been known at least since the 19th century that this rock was used for construction and sculpture in antiquity, and in the making of sarcophagi in the middle ages, the systematisation of the research on trachyte, carried out since 2008, has enabled us to make significant advances in the knowledge of its exploitation and dissemination. Geologists have established a detailed identity card of the six volcanoes where massive lava is available, thereby allowing the classification of eac…

Safety evaluation of turbo roundabout with and without internal traffic separations considering autonomous vehicles operation

The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been mixed with conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs compared to roundabouts without curbs. The paper shall also lead to describe the methodological path followed to build VISSIM models of turboroundabout with and without raised curbs, to calibrate the simulation mode…

Estimating traffic operations at multi-lane roundabouts: A case study

2014

This paper addresses traffic modeling issues at urban multi-lane roundabouts where, despite circulating vehicles have priority, negotiation of the right-of-way can occur between antagonist traffic flows, as a result of minor drivers’ failing to obey the nominal operating rule (stop or yield control). Existing models for the estimation of operational performances have the shortcoming of not representing the interdependencies between entering and circulating vehicles at multi-lane roundabouts. An analytical capacity model derived from field observations was developed for this kind of intersections in a previous study. The complexity of the model lies in the difficulty of observing the behavio…

LCA of Different Construction Choices for a Double-Track Railway Line for Sustainability Evaluations

2023

The international commitment to achieve carbon neutrality in the next few decades has oriented human activities towards the preservation of natural and non-renewable resources. In this context, a great research effort has been devoted to the search for sustainable solutions for the infrastructure construction sector, based on a thorough assessment of the environmental impact (EI). In this regards, Life Cycle Assessment (LCA) is considered one of the main components of Environmental Impact Assessment (EIA) and, for a comprehensive analysis, all the costs incurred by stakeholders during the useful life of the infrastructure should also be taken into account, applying the Life Cycle Cost (LCC)…

Modelli per l'interpretazione dei risultati di prove di push-out su travi reticolari miste

2011

Il comportamento sotto carico delle travi prefabbricate reticolari miste prima della pubblicazione delle nuove norme tecniche sulle costruzioni, veniva solitamente interpretato in analogia a quello di travi in c.a o a quello di travi miste acciao-calcestruzzo classicamente intese. L’esplicito riferimento nelle attuali norme a questa tipologia che viene trattata in un capitolo a parte, ha fatto scaturire l’esigenza di chiarezza e come conseguenza la pubblicazione di Linee Guida emanate dal C.S.LL.PP. che classificano le diverse tipologie in tre categorie: a) strutture composte acciaio-calcestruzzo; b) strutture in c.a. o in c.a.p.; c) strutture non riconducibili alle due categorie precedenti…
