  • Tandem repeats in Bacillus: Unique features and taxonomic distribution 

    Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2021-05-20)
    Article
    Open Access
    Little is known about DNA tandem repeats across prokaryotes. We have recently described an enigmatic group of tandem repeats in bacterial genomes with a constant repeat size but variable sequence. These findings strongly ...
  • Fast energy-optimal multi-kernel DNN-like application allocation on multi-FPGA platforms

    Article
    Open Access
    Platforms with multiple Field Programmable Gate Arrays (FPGAs), such as Amazon Web Services (AWS) F1 instances, can efficiently accelerate multi-kernel pipelined applications, e.g., Convolutional Neural Networks for machine ...
  • Knowledge-based segmentation to improve accuracy and explainability in non-technical losses detection 

    Calvo Ibáñez, Albert; Coma Puig, Bernat; Carmona Vargas, Josep; Arias Vicente, Marta (2020-10-30)
    Article
    Open Access
    Utility companies have a great interest in identifying energy losses. Here, we focus on Non-Technical Losses (NTL), which refer to losses caused by utility theft or meter errors. Typically, utility companies resort to ...
  • Automatic safe data reuse detection for the WCET analysis of systems with data caches 

    Segarra Flor, Juan; Cortadella, Jordi; Gran Tejero, Rubén; Viñals Yúfera, Victor (Institute of Electrical and Electronics Engineers (IEEE), 2020-10-19)
    Article
    Open Access
    Worst-case execution time (WCET) analysis of systems with data caches is one of the key challenges in real-time systems. Caches exploit the inherent reuse properties of programs, temporarily storing certain memory contents ...
  • Empowering conformance checking using Big Data through horizontal decomposition 

    Valencia Parra, Álvaro; Varela Vaca, Ángel Jesús; Gómez López, María Teresa; Carmona Vargas, Josep; Bergenthum, Robin (Elsevier, 2021-07)
    Article
    Restricted access - publisher's policy
    Conformance checking unleashes the full power of process mining: techniques from this discipline enable the analysis of the quality of a process model through the discovery of event data, the identification of potential ...
  • CNN-on-AWS: Efficient allocation of multikernel applications on Multi-FPGA platforms 

    Shan, Junnan; Lazarescu, Mihai T.; Cortadella, Jordi; Lavagno, Luciano; Casu, Mario R. (2021-02)
    Article
    Open Access
    Multi-FPGA platforms, like Amazon AWS F1, can run in the cloud multikernel pipelined applications, like convolutional neural networks (CNNs), with excellent performance and lower energy consumption than CPUs or GPUs. We ...
  • Uncovering de novo gene birth in yeast using deep transcriptomics 

    Blevins, William R.; Ruiz Orera, Jorge; Messeguer Peypoch, Xavier; Blasco Moreno, Bernat; Villanueva Cañas, José Luis; Espinar Calvo, Lorena; Díez Antón, Juana; Carey, Lucas B.; Albà Soler, M. Mar (2021-01-27)
    Article
    Open Access
    De novo gene origination has been recently established as an important mechanism for the formation of new genes. In organisms with a large genome, intergenic and intronic regions provide plenty of raw material for new ...
  • Alignment of virus-host protein-protein interaction networks by integer linear programming: SARS-CoV-2 

    Llabrés Segura, Mercè; Valiente Feruglio, Gabriel Alejandro (Public Library of Science (PLOS), 2020-12-07)
    Article
    Open Access
    Motivation: Beside socio-economic issues, coronavirus pandemic COVID-19, the infectious disease caused by the newly discovered coronavirus SARS-CoV-2, has caused a deep impact in the scientific community, that has ...
  • Anti-alignments—Measuring the precision of process models and event logs 

    Chatain, Thomas; Boltenhagen, Mathilde; Carmona Vargas, Josep (2021-05-01)
    Article
    Restricted access - publisher's policy
    Processes are a crucial artifact in organizations, since they coordinate the execution of activities so that products and services are provided. The use of models to analyze the underlying processes is a well-known practice. ...
  • Power-optimal mapping of CNN applications to cloud-based Multi-FPGA platforms 

    Shan, Junnan; Lazarescu, Mihai T.; Cortadella, Jordi; Lavagno, Luciano; Casu, Mario R. (2020-12)
    Article
    Open Access
    Multi-FPGA platforms like Amazon Web Services F1 are perfect to accelerate multi-kernel pipelined applications, like Convolutional Neural Networks (CNNs). To reduce energy consumption, we propose to upload at runtime the ...
  • Multi-level dataflow-driven macro placement guided by RTL structure and analytical methods 

    Vidal Obiols, Alexandre; Cortadella, Jordi; Petit Silvestre, Jordi; Galcerán Oms, Marc; Martorell Cid, Ferran (2020-12-28)
    Article
    Open Access
    When RTL designers define the hierarchy of a system, they exploit their knowledge about the conceptual abstractions devised during the design and the functional interactions between the logical components. This valuable ...
  • Unique features of tandem repeats in bacteria 

    Subirana Torrent, Juan A.; Messeguer Peypoch, Xavier (2020-08-24)
    Article
    Restricted access - publisher's policy
    DNA tandem repeats, or satellites, are well described in eukaryotic species, but little is known about their prevalence across prokaryotes. Here, we performed the most complete characterization to date of satellites in ...
