A new approach to covariate shift adaptation

A new approach to covariate shift adaptation

Computer scienceMathematicsRobotics

By BCAM

In probability theory and statistics, a collection of random variables is independent and identically distributed (iid) if each random variable has the same probability distribution as the others and all are mutually independent. Most supervised machine learning methods assume that training and testing or production samples are drawn iid from the same underlying distribution. But […]

Synchrony with chaos

Synchrony with chaos

BiologyMathematics

By Invited Researcher

Imagine an old-growth forest in the fading light of a summer evening. As the last of the sun’s rays disappear beneath the horizon, a tiny flash catches your eye. You turn around, hold your breath; it blinks again, hovering 2 feet above the leaf litter. Across the dusky glade, a fleeting response. Then another one […]

Fine-tuning wine fermentation processes

Fine-tuning wine fermentation processes

Chemical engineeringFood processingMathematics

By BCAM

Fermentation is a form of anaerobic respiration occurring in certain microorganisms, like yeasts. Many processes arising in diverse contexts can be classified as fermentation processes, such as manufacturing of some food products (baking, wine and beer industries are based on them) and of some industrial and pharmaceutical chemicals. Alcoholic fermentation comprises a series of biochemical […]

Modelling the new neuron-glial paradigm

Modelling the new neuron-glial paradigm

MathematicsNeuroscience

By BCAM

Modelling of neuron-glial interactions is an emerging field of Computational Neuroscience. The ubiquity of these interactions and the possibility that they may occur within the time and spatial scales that are usually ascribed to neuronal and synaptic function, calls for a revision of current neuron-based modeling paradigms to include potentially relevant effects mediated by glial […]

HOMA: a space orbit simulator

HOMA: a space orbit simulator

MathematicsPhysics

By BCAM

Quick simulations of space orbits and trajectories are essential in different aspects of space engineering, from the optimization of trajectories and orbit transfers, to the determination of the orbits themselves, altitude control, and gravitational modelling. Although the preliminary analysis of satellite space orbits can be done without extensive simulations, to represent the dynamical states of […]

Multiscale mathematical models for glioma progression

Multiscale mathematical models for glioma progression

BiomedicineMathematicsMedicine

By BCAM

Gliomas are the most prevalent subtype of primary brain tumours originating from mutations of the glia cells in the central nervous system. Gliomas are characterized by fast cell growth, strong invasion capability, and well-developed tumour vasculature. Although research and clinical trials have allowed significant progress in the comprehension and treatment of gliomas, they still have […]

HealthMathematicsMedicine

By BCAM

In March 2020, a multidisciplinary task force (so-called Basque Modelling Task Force, BMTF) was created to assist the Basque health managers and Government during the COVID-19 responses. BMTF works creating a model based on different approaches: stochastic processes, statistical methods and artificial intelligence. The efforts and challenges to develop a flexible modelling framework able to […]

By Pablo Rodríguez Sánchez

Preamble In the period 2015-2019, I was hired as a mathematician by a biology department in order to perform a research that eventually would become my doctoral thesis. This text is adapted from the last chapter of that thesis, “Cycles and interactions: A mathematician among biologists” (full text available here ). The symbiosis between mathematics […]

Major drivers of genetic differentiation in Iberian <i>Arabidopsis thaliana</i>

Major drivers of genetic differentiation in Iberian Arabidopsis thaliana

MathematicsPlant biology

By BCAM

Populations are not static, and the geographic distribution of genetic diversity within and among populations is changing continuously. The drivers of genetic differentiation is one of the cornerstones in evolution, as genetic diversity is paramount for the ability of populations to adapt and persist in changing environments. The spatio-temporal changes in genetic diversity constantly taking […]

Health-related quality of life in chronic obstructive pulmonary disease patients

MathematicsMedicine

By BCAM

Chronic diseases are already having and will continue to have not only profound economic, social and individual consequences but also a major impact on the use of health resources and design of new care processes. Chronic obstructive pulmonary disease (COPD) is a case on point. COPD is airflow limitation caused by an inflammatory response to […]
