Spectroscopy of short-lived radioactive molecules
2020
Molecular spectroscopy offers opportunities for the exploration of the fundamental laws of nature and the search for new particle physics beyond the standard model1–4. Radioactive molecules—in which one or more of the atoms possesses a radioactive nucleus—can contain heavy and deformed nuclei, offering high sensitivity for investigating parity- and time-reversal-violation effects5,6. Radium monofluoride, RaF, is of particular interest because it is predicted to have an electronic structure appropriate for laser cooling6, thus paving the way for its use in high-precision spectroscopic studies. Furthermore, the effects of symmetry-violating nuclear moments are strongly enhanced5,7–9 in molecu…
Ultrafast Coherent THz Lattice Dynamics Coupled to Spins in the van der Waals Antiferromagnet FePS3
2022
Coherent THz optical lattice and hybridized phonon–magnon modes are triggered by femtosecond laser pulses in the antiferromagnetic van der Waals semiconductor FePS3. The laser-driven lattice and spin dynamics are investigated in a bulk crystal as well as in a 380 nm-thick exfoliated flake as a function of the excitation photon energy, sample temperature and applied magnetic field. The pump-probe magneto-optical measurements reveal that the amplitude of a coherent phonon mode oscillating at 3.2 THz decreases as the sample is heated up to the Néel temperature. This signal eventually vanishes as the phase transition to the paramagnetic phase occurs, thus revealing its connection to the long-ra…
An Examination of Tourist Arrivals Dynamics Using Short-Term Time Series Data: A Space—Time Cluster Approach
2013
The purpose of this study is to examine the development of Italian tourist areas ( circoscrizioni turistiche) through a cluster analysis of short time series. The technique is an adaptation of the functional data analysis approach developed by Abraham et al (2003), which combines spline interpolation with k-means clustering. The findings indicate the presence of two patterns (increasing and stable) averagely characterizing groups of territories. Moreover, tests of spatial contiguity suggest the presence of ‘space–time clusters’; that is, areas in the same ‘time cluster’ are also spatially contiguous. These findings appear to be more robust in particular for those series characterized by an…
Approximation of measurements results of „EMERGENCY” signal reception probability
2017
W artykule przedstawiono wyniki aproksymacji przykładowych danych pomiaru prawdopodobieństwa odbioru sygnału NIEBEZPIECZEŃSTWO. Prawdopodobieństwo to rozpatruje się jako funkcję odległości pomiędzy statkiem powietrznym a systemem naziemnym w ustalonych warunkach pomiaru. Aproksymację danych pomiarowych zrealizowano korzystając z własności funkcji logistycznej. Prawdopodobieństwo jako funkcja odległości pozwala na określenie zasięgu sygnału NIEBEZPIECZEŃSTWO dla zadanego poziomu ufności.

The Spatial Overlap of Police Calls Reporting Street-Level and Behind-Closed-Doors Crime: A Bayesian Modeling Approach
2021
Traditionally, intimate-partner violence has been considered a special type of crime that occurs behind closed doors, with different characteristics from street-level crime. The aim of this study is to analyze the spatial overlap of police calls reporting street-level and behind-closed-doors crime. We analyzed geocoded police calls in the 552 census-block groups of the city of Valencia, Spain, related to street-level crime (N = 26,624) and to intimate-partner violence against women (N = 11,673). A Bayesian joint model was run to analyze the spatial overlap. In addition, two Bayesian hierarchical models controlled for different neighborhood characteristics to analyze the relative risks. Resu…
Memoria Autobiográfica y Atención. Perspectiva Cognitiva y Experimental.
2017
RESUMEN TESIS Título: Memoria Autobiográfica y Atención. Una perspectiva cognitiva y experimental. Doctoranda: Ana Isabel Agustí López Director de tesis: Juan Carlos Meléndez Moral Este trabajo plantea dos cuestiones u objetivos generales, en primer lugar se pretende comprobar si al estudiar la memoria autobiográfica (MA) existen diferencias entre jóvenes y adultos mayores no solamente en relación al tipo de memoria (episódica y semántica) sino también en relación al componente emocional asociado a los recuerdos y la distribución temporal del recuerdo (infancia/ adolescencia, bump de reminiscencia y recuerdos recientes). En segundo lugar, se pretende estudiar la atención mediante tareas de …
Coping with Uncertainty in an Agile Systems Development Course
2018
Uncertain and ambiguous environments are commonplace in information systems development (ISD) projects, and while different Agile frameworks welcome changes in organizational, technical, and business environments, the incurred uncertainty is known to negatively affect the development process and the quality of the final product. The effects of uncertainty on ISD projects have been studied in the past in real organizational contexts, but the effects of uncertainty on students in Agile systems development have received less attention from scholars. In this study, we measured the effects of experienced uncertainty on students’ performance in an Agile systems development course and how uncertai…
A Sub-Supersolution Approach for Robin Boundary Value Problems with Full Gradient Dependence
2020
The paper investigates a nonlinear elliptic problem with a Robin boundary condition, which exhibits a convection term with full dependence on the solution and its gradient. A sub- supersolution approach is developed for this type of problems. The main result establishes the existence of a solution enclosed in the ordered interval formed by a sub-supersolution. The result is applied to find positive solutions.
On the Sub-Supersolution Approach for Dirichlet Problems driven by a (p(x), q(x))-Laplacian Operator with Convection Term
2021
The method of sub and super-solution is applied to obtain existence and location of solutions to a quasilinear elliptic problem with variable exponent and Dirichlet boundary conditions involving a nonlinear term f depending on solution and on its gradient. Under a suitable growth condition on the convection term f, the existence of at least one solution satisfying a priori estimate is obtained.
