Topological surface wave metamaterials for robust vibration attenuation and energy harvesting
2021
International audience; We propose topological metamaterials working in Hertz frequency range, constituted of concrete pillars on the soil ground in a honeycomb lattice. Based on the analog of the quantum valley Hall effect, a non-trivial bandgap is formed by breaking the inversion symmetry of the unit cell. A topological interface is created between two different crystal phases whose robustness against various defects and disorders is quantitatively analyzed. Finally, we take advantage of the robust and compact topological edge state for designing a harvesting energy device. The results demonstrate the functionality of the proposed structure for both robust surface vibration reduction and …
The Large Hadron–Electron Collider at the HL-LHC
2021
The Large Hadron-Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron-proton and proton-proton operations. This report represents an update to the LHeC's conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LH…

Nowa polityka. Wprowadzenie do ewolucyjności
2017
This article introduces a vision of the new politics that emerges from my recent book Tractatus Politico‑Philosophicus. The Tractatus discusses a number of topics. To name just a few, these are: politics, human nature, the state, freedom, solidarity, democracy, civilization, family and marriage, power, international relations, war and peace. Also, it introduces new words, such as sophocracy, ennobled democracy; nativeculturalism (an alternative to multiculturalism); or parentsexuality, a privileged form of sexuality. It addresses many issues that concern today’s political thinkers. The main objective of my work is to demonstrate the necessity of, and provide a guide for, the redirection of …
Un mondo senza confini, un potere senza limiti. Temi e retoriche identitarie dell’«eccezionalismo» ateniese
2022
Partendo dalla categoria politica di “eccezionalismo”, che è stata utilizzata per descrivere la politica estera degli Stati Uniti, soprattutto nel XX secolo, questo paper propone una analisi comparata con la politica ateniese di V secolo, soprattutto durante il suo impero marittimo: in tale contesto la nozione di “eccezionalismo” sembra adatta per comprendere alcuni aspetti della sua politica e i rapporti tra “eccezionalismo” e democrazia. Starting with the political category of 'exceptionalism', which has been used to describe US foreign policy, especially in the 20th century, this paper proposes a comparative analysis with 5th century Athenian policy, especially during its maritime empire…
Effects of Hippocampal State-Contingent Trial Presentation on Hippocampus-Dependent Nonspatial Classical Conditioning and Extinction
2014
Hippocampal local field potentials are characterized by two mutually exclusive states: one characterized by regular θ oscillations (∼4–8 Hz) and the other by irregular sharp-wave ripples. Presenting stimuli during dominant θ oscillations leads to expedited learning, suggesting that θ indexes a state in which encoding is most effective. However, ripple-contingent training also expedites learning, suggesting that any discrete brain state, much like the external context, can affect learning. We trained adult rabbits in trace eyeblink conditioning, a hippocampus-dependent nonspatial task, followed by extinction. Trials were delivered either in the presence or absence of θ or regardless of hippo…
Why are there no comprehensively digital scholarly editions of classical texts?
2018
Currently, no 'canonical' classical text with a multi-testimonial tradition has a digital scholarly edition based on a complete digital transcription of all primary sources, and on the automated collation of those transcriptions. Most classicists simply do not feel that they need such editions. I argue that this is ultimately due to the 'canonization' of the corpus of classical texts. Classicists are more focussed on the 'Text' than on the documents (manuscripts) and their texts: they tend not to consider the textual variance in the manuscripts as culturally meaningful in itself, but merely instrumental in view of the constitutio textus. I suspect that we will not have 'comprehensively digi…
Equilibrium fluid-crystal interfacial free energy of bcc-crystallizing aqueous suspensions of polydisperse charged spheres
2015
The interfacial free energy is a central quantity in crystallization from the meta-stable melt. In suspensions of charged colloidal spheres, nucleation and growth kinetics can be accurately measured from optical experiments. In previous work, from this data effective non-equilibrium values for the interfacial free energy between the emerging bcc-nuclei and the adjacent melt in dependence on the chemical potential difference between melt phase and crystal phase were derived using classical nucleation theory. A strictly linear increase of the interfacial free energy was observed as a function of increased meta-stability. Here, we further analyze this data for five aqueous suspensions of charg…
Fractional Maximal Functions in Metric Measure Spaces
2013
Abstract We study the mapping properties of fractional maximal operators in Sobolev and Campanato spaces in metric measure spaces. We show that, under certain restrictions on the underlying metric measure space, fractional maximal operators improve the Sobolev regularity of functions and map functions in Campanato spaces to Hölder continuous functions. We also give an example of a space where fractional maximal function of a Lipschitz function fails to be continuous.
