The science and management of infectious disease are entering a new stage. Increasingly public policy to manage epidemics focuses on motivating people, through social distancing policies, alter their behavior reduce contacts risk. Person-to-person drive human dynamics. People value such willing accept some risk gain contact-related benefits. cost–benefit trade-offs that shape contact behavior, hence the course epidemics, often only implicitly incorporated in epidemiological models. This...
We present a new, updated version of the EuclidEmulator (called EuclidEmulator2), fast and accurate predictor for nonlinear correction matter power spectrum. Percent-level emulation is now supported in eight-dimensional parameter space $w_0w_a$CDM$+\sum m_\nu$models between redshift $z=0$ $z=3$ spatial scales within range 0.01 $h$/Mpc $\leq k \leq$ 10 $h$/Mpc. In order to achieve this level accuracy, we have had improve quality underlying N-body simulations used as training data: (1) use...
Mathematical epidemiology, one of the oldest and richest areas in mathematical biology, has significantly enhanced our understanding how pathogens emerge, evolve, spread. Classical epidemiological models, standard for predicting managing spread infectious disease, assume that contacts between susceptible individuals depend on their relative frequency population. The behavioral factors underpin contact rates are not generally addressed. There is, however, an emerging a class models addresses...
Abstract The metamaterial paradigm has allowed an unprecedented space-time control of various physical fields, including elastic and acoustic waves. Despite the wide variety configurations proposed so far, most existing solutions display a frequency response that cannot be tuned, once structures are fabricated. Few exceptions include systems controlled by electric or magnetic temperature, radio waves mechanical stimuli, which may often unpractical for real-world implementations. To overcome...
The dynamics, control, and evolution of communicable vector-borne diseases are intimately connected to the joint dynamics epidemiological, behavioral, mobility processes that operate across multiple spatial, temporal, organizational scales. identification a theoretical explanatory framework accounts for pattern regularity exhibited by large number host-parasite systems, including those sustained host-vector epidemiological is but one challenges facing coevolving fields computational,...
We present a tomographic weak lensing analysis of the Kilo Degree Survey Data Release 4 (KiDS-1000), using new pseudo angular power spectrum estimator (pseudo- C ℓ ) under development for ESA Euclid mission. Over 21 million galaxies with shape information are divided into five redshift bins, ranging from 0.1 to 1.2 in photometric redshift. measured pseudo- eight bands multipole range 76 < 1500 auto- and cross-power spectra between bins. A series tests were carried out check systematic...
We aimed to test the hypothesized role of shared body size norms in social contagion and obesity.
The susceptible-infected-recovered (SIR) model has greatly evidenced epidemiology despite its apparent simplicity. Most applications of the SIR framework use a form nonlinear incidence to describe number new cases per instant. We adapt theorems analyze stability models with generalized structure. These are then applied case standard and resulting from adaptive behavioral response based on epidemiological-economic theory. When behavior is included in multiple equilibria oscillatory...
In this paper we present the framework for measuring angular power spectra in Euclid mission. The observables galaxy surveys, such as clustering and cosmic shear, are not continuous fields, but discrete sets of data, obtained only at positions galaxies. We show how to compute data sets, without treating observations maps an underlying field that is overlaid with a noise component. This formalism allows us exact theoretical expectations our measured spectra, under number assumptions track...
We present a machine learning framework to simulate realistic galaxies for the Euclid Survey. The proposed method combines control on galaxy shape parameters offered by analytic models with surface brightness distributions learned from real Hubble Space Telescope observations deep generative models. field of $0.4\,\rm{deg}^2$ as it will be seen visible imager VIS and show that structural are recovered similar accuracy pure S\'ersic profiles.

Upcoming surveys will map the growth of large-scale structure with unprecented precision, improving our understanding dark sector Universe. Unfortunately, much cosmological information is encoded by small scales, where clustering matter and effects astrophysical feedback processes are not fully understood. This can bias estimates parameters, which we study here for a joint analysis mock Euclid cosmic shear Planck microwave background data. We use different implementations modelling signal on...
