Morita homotopy theory for $(\infty, 1)$-categories and $\infty$-operads
We prove the existence of Morita model structures on the categories of small simplicial categories, simplicial sets, simplicial operads and dendroidal sets, modelling the Morita homotopy theory of $(\infty, 1)$-categories ...
Machine Learning Based Surrogate Model for Press Hardening Process of 22MnB5 Sheet Steel Simulation in Industry 4.0
The digitalization of manufacturing processes offers great potential in quality control, traceability, and the planning and setup of production. In this regard, process simulation is a well-known technology and a key step ...
High-resolution synthesis of high-density breast mammograms: Application to improved fairness in deep learning based mass detection
Computer-aided detection systems based on deep learning have shown goodperformance in breast cancer detection. However, high-density breasts showpoorer detection performance since dense tissues can mask or even simulatemasses. ...
Stable solutions to semilinear elliptic equations are smooth up to dimension 9
In this paper we prove the following long-standing conjecture: stable solutions to semi-linear elliptic equations are bounded (and thus smooth) in dimension $n \leqslant 9$. This result, that was only known to be true for ...
WCE polyp detection with triplet based embeddings
Wireless capsule endoscopy is a medical procedure used to visualize the entire gastrointestinal tractand to diagnose intestinal conditions, such as polyps or bleeding. Current analyses are performedby manually inspecting ...
Bilinear forms on weighted Besov spaces
We compute the norm of some bilinear forms on products of weighted Besov spaces in terms of the norm of their symbol in a space of pointwise multipliers related to a space of Carleson measures.
Systems of stochastic Poisson equations: Hitting probabilities
We consider a -dimensional random field that solves a system of elliptic stochastic equations on a bounded domain , with additive white noise and spatial dimension . Properties of and its probability law are proved. For ...
La proyección plana genérica de una curva alabeada
Sea y una rama de curva algebraica con origen en un punto p del espacio proyectivo complejo de dimensión tres, P3. A principios del presente siglo se admitía como resultado establecido la coincidencia de la composición de ...
New mechanisms for lack of equipartition of energy
We describe several mechanisms that prevent equipartition of energy in mechanical systems. In certain regimes, we present a quantitative prediction of the relative abundance of orbits exhibiting these mechanisms. This ...
On global solutions to semilinear elliptic equations related to the one-phase free boundary problem
Motivated by its relation to models of flame propagation, we study globally Lipschitz solutions of $\Delta u=f(u)$ in $\mathbb{R}^n$, where $f$ is smooth, nonnegative, with support in the interval $[0,1]$. In such setting, ...
On the bicanonical map of irregular varieties
From the point of view of uniform bounds for the birationality of pluricanonical maps, irregular varieties of general type and maximal Albanese dimension behave similarly to curves. In fact Chen-Hacon showed that, at least ...
From Gambling to Random Modelling
Among mathematical fields, probability stands out because of its short history and peculiar origins. Startingwith the analysis of games of chance, probability developed as the mathematical theory of uncertainty, andnowadays ...
Chasing spammers: Using the Internet protocol address fordetection
The proliferation of reviews evaluating different services on social networks andonline platforms and their importance in consumer decision‐making has led someunscrupulous individuals to take advantage of the anonymity ...
MISMIS: Misinformation and Miscommunication in social media: aggregating information and analysing language
The general objectives of the project are to address and monitor misinformation (biased and fake news) and miscommunication (aggressive language and hate speech) in social media, as well as to establish a high quality ...
Minimising multi-centre radiomics variability through image normalisation: A pilot study
Radiomics is an emerging technique for the quantification of imaging data that has recently shown great promise for deeper phenotyping of cardiovascular disease. Thus far, the technique has been mostly applied in single-centre ...
Modeling river flow for flood forecasting: A case study on the Ter river
Floods affect chronically many communities around the world. Their socioeconomic impact increases year-by-year, boosted by global warming and climate change. Combined with long-term preemptive measures, preparatory actions ...
Assessment Of Intra-coronary Stent Location And Extension In Intravascular Ultrasound Sequences.
Purpose An intraluminal coronary stent is a metal scaffold deployed in a stenotic artery during percutaneous coronary intervention (PCI). In order to have an effective deployment, a stent should be optimally placed with ...
Topological features of multivariate distributions: Dependency on the covariance matrix
Topological data analysis provides a new perspective on many problems in the domain of complex systems. Here, we establish the dependency of mean values of functional $p$ norms of 'persistence landscapes' on a uniform ...
Gaussian Process for Radiance Functions on the $\mathbb{s}^2$ Sphere
Efficient approximation of incident radiance functions from a set of samples is still an open problem in physically based rendering. Indeed, most of the computing power required to synthesize a photo-realistic image is ...
Intelligent Agricultural Machinery Using Deep Learning
Artificial intelligence, deep learning, big data, self-driving cars, these are words that have become familiar to most people and have captured the imagination of the public and have brought hopes as well as fears. We have ...
