Capturing the style of fake news
Comunicació presentada a la AAAI Conference on Artificial Intelligence (AAAI-20) 2020 , celebrada a New York (USA) del 7 al 12 de febrer de 2020.
Can input statistics over-ride a prior bias in morpheme ordering? a test case with gender and number
In languages which mark both gender and number as distinct morphemes, there is a tendency to place gender closer to the noun stem than number. However, the typological data on this is sparse. Moreover, linguistic theories ...
Formal governance matters: when, how, and why states act on the IMF Executive Board
International financial institutions (IFIs) are central actors shaping global development. Scholarship on these institutions' governance has primarily explored unequal voting rights and informal channels of decision-making. ...
Sensitivity to the sonority sequencing principle in rats (Rattus norvegicus)
Albeit diverse, human languages exhibit universal structures. A salient example is the syllable, an important structure of language acquisition. The structure of syllables is determined by the Sonority Sequencing Principle ...
Multilevel irreversibility reveals higher-order organization of nonequilibrium interactions in human brain dynamics
Information processing in the human brain can be modeled as a complex dynamical system operating out of equilibrium with multiple regions interacting nonlinearly. Yet, despite extensive study of the global level of ...
Neonatal brain dynamic functional connectivity in term and preterm infants and its association with early childhood neurodevelopment
Brain dynamic functional connectivity characterises transient connections between brain regions. Features of brain dynamics have been linked to emotion and cognition in adult individuals, and atypical patterns have been ...
Scale-free behavior of weight distributions of connectomes
To determine the precise link between anatomical structure and function, brain studies primarily concentrate on the anatomical wiring of the brain and its topological properties. In this work, we investigate the weighted ...
Perturbing whole-brain models of brain hierarchy: an application for depression following pharmacological treatment
Determining the scale of neural representations is a central challenge in neuroscience. While localized representations have traditionally dominated, evidence suggests information is also encoded in distributed, hierarchical ...
SAR image compression using adaptive differential evolution and pattern search based k-means vector quantization
A novel Vector Quantization (VQ) technique for encoding the Bi-orthogonal wavelet decomposed image using hybrid Adaptive Differential Evolution (ADE) and a Pattern Search optimization algorithm (hADEPS) is proposed. ADE ...
Dietary intake of Perfluorooctanesulfonic acid (PFOS) and glucose homeostasis parameters in a non-diabetic senior population
Background: Endocrine disruptors (EDs) have emerged as potential contributors to the development of type-2 diabetes. Perfluorooctane sulfonate (PFOS), is one of these EDs linked with chronic diseases and gathered attention ...
Emergence and maintenance of modularity in neural networks with Hebbian and anti-Hebbian inhibitory STDP
The modular and hierarchical organization of the brain is believed to support the coexistence of segregated (specialization) and integrated (binding) information processes. A relevant question is yet to understand how such ...
LSD flattens the hierarchy of directed information flow in fast whole-brain dynamics
Psychedelics are serotonergic drugs that profoundly alter consciousness, yet their neural mechanisms are not fully understood. A popular theory, RElaxed Beliefs Under pSychedelics (REBUS), posits that psychedelics flatten ...
Non-local Schrödinger diffusion model reveals mechanisms of critical brain dynamics
Time-efficient computation is essential for survival. It has been proposed that this is made possible through the principle of criticality amplified by the rare long-range connections found in the brain's unique ...
Shannon and Fuzzy entropy based evolutionary image thresholding for image segmentation
Image segmentation is a very important and pre-processing step in image analysis. The conventional multilevel thresholding methods are efficient for bi-level thresholding because of its simplicity, robustness, less convergence ...
Image compression based on vector quantization using cuckoo search optimization technique
Most common vector quantization (VQ) is Linde Buzo Gray (LBG), that designs a local optimal codebook for image compression. Recently firefly algorithm (FA), particle swarm optimization (PSO) and Honey bee mating optimization ...
Transient destabilization of whole brain dynamics induced by N,N-Dimethyltryptamine (DMT)
The transition towards the brain state induced by psychedelic drugs is frequently neglected in favor of a static description of their acute effects. We use a time-dependent whole-brain model to reproduce large-scale brain ...
Spain: Emergences, strategies and limitations of Spanish transmedia productions
Today's convergent media industries readily produce stories that span multiple media, telling the tales of superheroes across comics, film and television, inviting audiences to participate in the popular universes ...
Bridging sectors and disciplines to gain a critical understanding of the eco-social determinants of health inequities: the ESDHI-EU Conference
The current eco-social crisis is driven by an unsustainable socioeconomic model based on continued economic growth that exceeds planetary limits. Groups experiencing disadvantages are being disproportionately affected, ...
Pasta consumption and cardiometabolic risks in older adults with overweight/obesity: a longitudinal analysis
Objective: Low Glycemic Index (GI) diets improve cardiometabolic risk (CMR) specifically in those with insulin resistance. However, the prospective association between pasta (a low GI staple) consumption and CMR is unclear. ...
