Bootstrap forecasts of multivariate time series

, 2014
En esta tesis se estudia el desempeño de procedimientos que tienen por objetivo la aproximación de densidades de predicción y sus respectivos intervalos y regiones de confianza en series de tiempos multivariantes. En concreto, desarrollamos procedimientos bootstrap para predecir los modelos VAR y DCC, utilizados a menudo en la modelización y predicción

Time‐Delayed Spiking Reservoir Computing Enables Efficient Time Series Prediction

Advanced Intelligent Systems, EarlyView.
This study proposes time‐delayed spiking reservoir computing (TDSRC) for efficient time series prediction. By concatenating time‐lagged states, TDSRC constructs an expanded readout feature vector without altering internal reservoir dynamics. This approach enables highly accurate forecasting with significantly fewer neurons, providing a resource ...

Clinical Predictors of Response in Chronic Graft‐Versus‐Host Disease: Results From the “Predicting the Quality of Response to Specific Treatments (PQRST)” Trial

American Journal of Hematology, EarlyView.
ABSTRACT Despite significant progress in chronic GVHD therapies, challenges remain in understanding pleomorphic phenotypes and varying responses to treatment. The aim of this study was to identify predictors of treatment response. We conducted a prospective, observational cohort study of patients beginning first‐, second‐, or third‐line systemic ...

A Global Prospective Harmonization Framework for Suicidality, Anhedonia, and Obsessive‐Compulsive Symptoms in Psychiatric Genetic Studies: A Cross‐Continental Study Within the Ancestral Population Network

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT This study aims to prospectively collect harmonized, quantitative, and dimensional psychiatric phenotypes (suicidality, anhedonia, and obsessive‐compulsive symptoms) and information on discrimination, stigma, and unfair treatment in up to 27,500 individuals across diverse ancestries and clinical populations for genetic analysis within the NIMH

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...
