Strongly Coupled Coherent Phonons in Single-Layer MoS 2
2019
We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution ($\sim$20fs) which is ideally suited to trigger and detect vibrational coherences in different classes of materials. We generate and detect coherent phonons (CPs) in single layer (1L) MoS$_2$, as a representative semiconducting 1L-transition metal dichalcogenide (TMD), where the confined dynamical interaction between excitons and phonons is unexplored. The coherent oscillatory motion of the out-of-plane $A'_{1}$ phonons, triggered by the ultrashort laser pulses, dynamically modulates the excitonic resonances on a timescale of few tens fs. We observe an enhancement by…

Adaptation to fluctuations in temperature by nine species of bacteria.
2017
Abstract Rapid environmental fluctuations are ubiquitous in the wild, yet majority of experimental studies mostly consider effects of slow fluctuations on organism. To test the evolutionary consequences of fast fluctuations, we conducted nine independent experimental evolution experiments with bacteria. Experimental conditions were same for all species, and we allowed them to evolve either in fluctuating temperature alternating rapidly between 20°C and 40°C or at constant 30°C temperature. After experimental evolution, we tested the performance of the clones in both rapid fluctuation and in constant environments (20°C, 30°C and 40°C). Results from experiments on these nine species were comb…

El redreçament nacionalista valencià des del setmanari valencianista - El Camí - (1932 - 1934)
2022
La Tesi doctoral: “El redreçament nacionalista valencià des del setmanari valencianista El Camí (1932-1934).” L’objectiu de la Tesi és la importància del setmanari valencianista en la història cultural contemporània del País Valencià, dins dels periòdics nacionalistes valencians del primer terç del segle XX. La Tesi s’articula en cinc capítols. En el primer capítol, s’analitzen les persones –col•laboradors- que escriuen en el setmanari, una mena de Dramatis Personae, per mostrar quins temes aborden, quin és el propòsit del setmanari i quins són els objectius dels seus editors, arran de la pluralitat d’opinions vessades en la revista En el primer capítol de la Tesi s’ha volgut analitzar quin…
TISSBERT: A benchmark for the validation and comparison of NDVI time series reconstruction methods
2018
[EN] This paper introduces the Time Series Simulation for Benchmarking of Reconstruction Techniques (TISSBERT) dataset, intended to provide a benchmark for the validation and comparison of time series reconstruction methods. Such methods are routinely used to estimate vegetation characteristics from optical remotely sensed data, where the presence of clouds decreases the usefulness of the data. As for their validation, these methods have been compared with previously published ones, although with different approaches, which sometimes lead to contradictory results. We designed the TISSBERT dataset to be generic so that it could simulate realistic reference and cloud-contaminated time series …
Regolazione e concorrenza
2014
lo studio esamina i rapporti fra Regolazione e concorrenza evidenziando che il grande tema che si pone, è quello della dimensione della regolazione. Se la tutela della concorrenza ha una sicura dimensione europea – con le Autorità antitrust nazionali che operano all’interno di un network europeo, dialogando costantemente con la Commissione e applicano direttamente il diritto europeo – la frammentazione della regolazione secondo linee nazionali costituisce un grosso ostacolo allo sviluppo di quel mercato unico che, se pienamente realizzato, potrebbe essere uno dei principali modi per riprendere il sentiero della crescita economica.
Cautionary note on the two-step transformation to normality
2020
Templeton and Burney (2017) proposed a two-step normality transformation as a remedy for non-normally distributed data, which are commonly found in AIS research. We argue that, rather than transforming the data toward normality, researchers should first seek to analyze and understand the sources of non-normality. Using simulated datasets, we demonstrate three sources of non-normality and their consequences for regression estimation. We then demonstrate that the two-step transformation cannot solve any of these problems and that each source of non-normality can be handled with alternative, existing techniques. We further present two empirical examples to demonstrate these issues with real da…
Four-dimensional representation of scattering amplitudes and physical observables through the application of the Loop-Tree Duality theorem
2019
Las últimas dos décadas han sido testigo de un tremendo progreso en la física teórica de alta precisión. Muchos avances han sido hechos, en particular, en la evaluación de diagramas multi-loop, pero el principal desafío yace en el tratamiento de las divergencias IR a través de eficientes esquemas de substracción. Con la complejidad del procedimiento incrementándose exponencialmente con el número de escalas, se ha hecho necesario tratar la cuestión desde un ángulo diferente, invocando así al desarrollo de nuevas técnicas. La Dualidad Lazo-Árbol (LTD, por sus siglas en inglés) provee de un nuevo marco para el cómputo de amplitudes con loops. A través de la modificación de la prescripción está…
