A Deep Double Ritz Method (D2RM) for solving Partial Differential Equations using Neural Networks
(Elsevier, 202302)Residual minimization is a widely used technique for solving Partial Differential Equations in variational form. It minimizes the dual norm of the residual, which naturally yields a saddlepoint (min–max) problem over the ... 
A Fair and Scalable Mechanism for Resource Allocation: The Multilevel QPQ Approach
(IEEE, 20201229)In this paper the problem of distributing resources among a collection of users (or players) is explored. These players have independent preferences to get these resources and can be dishonest about their preferences in ... 
A family of finite pgroups satisfying Carlson's depth conjecture
(Wiley, 202206)Let p > 3 be a prime number and let r be an integer with 1 < r < p  1. For each r, let moreover G(r) denote the unique quotient of the maximal class prop group of size p(r+1).We show that the modp cohomology ring of ... 
A Finite Element based Deep Learning solver for parametric PDEs
(Elsevier, 202203)We introduce a dynamic Deep Learning (DL) architecture based on the Finite Element Method (FEM) to solve linear parametric Partial Differential Equations (PDEs). The connections between neurons in the architecture mimic ... 
A general insertion theorem for uniform locales
(Elsevier, 202307)A general insertion theorem due to Preiss and Vilimovský is extended to the category of locales. More precisely, given a preuniform structure on a locale we provide necessary and sufficient conditions for a pair f ≥ g ... 
A geometric and physical study of Riemann's nondiferentiable function.
(20200708)Riemann's nondifferentiable function is a classic example of a continuous but almost nowheredifferentiable function, whose analytic regularity has been widely studied since it was proposedin the second half of the 19th ... 
A Machine Learning Model for the Prognosis of Pulseless Electrical Activity during OutofHospital Cardiac Arrest
(MDPI, 20210630)Pulseless electrical activity (PEA) is characterized by the disassociation of the mechanical and electrical activity of the heart and appears as the initial rhythm in 20–30% of outofhospital cardiac arrest (OHCA) cases. ... 
A mathematical analysis of EDAs with distancebased exponential models
(Springer, 2022)Estimation of Distribution Algorithms have been successfully used to solve permutationbased Combinatorial Optimization Problems. In this case, the algorithms use probabilistic models specifically designed for codifying ... 
A prop group with full normal Hausdorff spectra
(Wiley, 202201)[EN] For each odd prime p, we produce a 2generated prop group G whose normal Hausdorff spectra hspec((sic))(S)(G) = {hdim(G)(S) (H) vertical bar (sic)(c) G} with respect to five standard filtration series S, namely ... 
A revisited branchandcut algorithm for largescale orienteering problems
(Elsevier, 202402)The orienteering problem is a route optimization problem which consists of finding a simple cycle that maximizes the total collected profit subject to a maximum distance limitation. In the last few decades, the occurrence ... 
A stochastic programming model for ambulance (re)location–allocation under equitable coverage and multiinterval response time
(Elsevier, 20240325)Emergency Medical Services are essential for health systems as their effective management can improve patient prognosis. Nevertheless, designing an optimized distribution of resources is a difficult task due to the ... 
A theory of quantaleenriched dcpos and their topologization
(Elsevier, 202209)There have been developed several approaches to a quantalevalued quantitative domain theory. If the quantale Q is integral and commutative, then Qvalued domains are Qenriched, and every Qenriched domain is sober in ... 
A Universal AntigenRanking Method to Design Personalized Vaccines Targeting Neoantigens against Melanoma
(MDPI, 20230105)Background: The main purpose of this article is to introduce a universal mathematicsaided vaccine design method against malignant melanoma based on neoantigens. The universal method can be adapted to the mutanome of each ... 
Advanced mathematical modelling of pancreatic Bcells
(20191210)[EN*Insulinsecreting pancreatic ßcells are responsible for maintaining the whole body glucosehomeostasis. Dysfunction or loss of ßcell mass results in impaired insulin secretion and, in somecases, diabetes. In this ...

Age of Information in a Decentralized Network of Parallel Queues with Routing and Packets Losses
(Korean Institute of Communications and Information Sciences, 202202)The paper deals with age of information (AoI) in a network of multiple sources and parallel queues with buffering capabilities, preemption in service and losses in served packets. The queues do not communicate between each ... 
Age of Information of a Server with Energy Requirements
(PeerJ, 20210301)We investigate a system with Poisson arrivals to two queues. One queue stores the status updates of the process of interest (or data packets) and the other handles the energy that is required to deliver the updates to the ... 
Age of Information of Parallel Server Systems with Energy Harvesting
(MDPI, 20211121)Motivated by current communication networks in which users can choose different transmission channels to operate and also by the recent growth of renewable energy sources, we study the average Age of Information of a status ... 
Age or lifestyleinduced accumulation of genotoxicity is associated with a lengthdependent decrease in gene expression
(Elsevier, 202304)DNA damage has long been advocated as a molecular driver of aging. DNA damage occurs in a stochastic manner, and is therefore more likely to accumulate in longer genes. The lengthdependent accumulation of transcriptionblocking ...
