Partial least squares models and their formulations, diagnostics and applications to spectroscopy 

Huerta, Mauricio; Leiva, Víctor; Marchant-Fuentes, Carolina; Rodríguez-Gallardo, Marcelo (2020)
Partial least squares (PLS) models are a multivariate technique developed to solve the problem of multicollinearity and/or high dimensionality related to explanatory variables in multiple linear models. PLS models have ...

Differential involvement of left and right frontoparietal areas in visuospatial planning: An rTMS study 

Basso, Demis; Saracini, Chiara (2020)
The planning process consists of pre-determining an ordered series of actions to accomplish a goal. Previous research showed that the left prefrontal cortex (PFC) is likely to create the strategy for a plan, while the right ...

Finite field metrics applied to M-FSK modulation in VLC systems 

Guajardo-Penroz, Cristobal; Soto, Ismael; San-Juan, Enrique; Adasme, Pablo; Azurdia-Meza, Cesar A.; Zabala-Blanco, David (2020)
This paper provides an alternative to digital filter based frequency detection for multi-frequency shift keying modulation (M-FSK) using field programmable gate array (FPGA) architectures, by providing a hamming space ...

Penicillium spp. mycotoxins found in food and feed and their health effects 

Otero, C.; Arredondo, C.; Echeverría-Vega, Alex; Gordillo-Fuenzalida, Felipe (2020)
Mycotoxins are toxic secondary metabolites produced by fungi. These compounds have different structures and target different organs, acting at different steps of biological processes inside the cell. Around 32 mycotoxins ...

A comparison of stochastic gradient MCMC using multi-core and GPU architectures 

Hernández, Sergio; Valdés, José; Valdenegro, Matias (2020)
Deep learning models are traditionally used in big data scenarios. When there is not enough training data to fit a large model, transfer learning re-purpose the learned features from an existing model and re-train the lower ...

Stand structure, regeneration and seed dispersal patterns of nothofagus glauca (hualo) in central Chile 

Navarro-Cerrillo, Rafael M.; Cabrera-Ariza, Antonio; Avaria, Antonio; Palacios-Rodríguez, Guillermo; Santelices-Moya, Rómulo (2020)
Growing interest in functional silviculture is promoting new approaches to the study of seed dispersal and regeneration, two of the key processes that determine the structure and dynamics of plant populations. Nothofagus ...

Biotransformation of poly(cis-1,4-isoprene) in a multiphase enzymatic reactor for continuous extraction of oligo-isoprenoid molecules 

Andler-Osorio, Rodrigo; Valdés, Cristian; Díaz-Barrera, Álvaro; Steinbüchel, A. (2020)
Biotechnological processes for the partial degradation or transformation of poly(cis-1,4-isoprene) rubber have been investigated during recent decades with promising results. The use of the enzyme ‘latex clearing protein’ ...

State-dependent tms over prefrontal cortex disrupts fear-memory reconsolidation and prevents the return of fear 

Borgomaneri, Sara; Battaglia, Simone; Garofalo, Sara; Tortora, Francesco; Avenanti, Alessio; di Pellegrino, Giuseppe (2020)
Erasing maladaptive memories has been a challenge for years. A way to change fear memories is to target the process of reconsolidation, during which a retrieved memory transiently returns to a labile state, amenable to ...
