Reciprocal Benefits of Mass-Univariate and Multivariate Modeling in Brain Mapping: Applications to Event-Related Functional MRI, H215O-, and FDG-PET

International Journal of Biomedical Imaging, 2006
In brain mapping studies of sensory, cognitive, and motor operations, specific waveforms of dynamic neural activity are predicted based on theoretical models of human information processing. For example in event-related functional MRI (fMRI), the general

GLM-based w_AV and Bayesian modelling analysis overview.

, 2019
(A) The GLM-based wAV and Bayesian modelling analysis were performed on auditory (‘A’) and visual (‘V’) spatial estimates that were indicated by participants as behavioural localisation responses (left, ‘Behaviour’) or decoded from participants’ EEG ...

Harnessing the Potential of LLMs in Hospital Management: Insights Into Medical Data Inquiry

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Background Considering the rapid expansion of hospital operations and the increasing digitisation of medical data, there is a pressing need for efficient and intelligent methods to process and analyse large‐scale medical data. Methods We integrated the QLoRA algorithm with ChatGLM2‐6b, Llama2‐7b, and Llama2‐13b models, fine‐tuning them on a ...

Definition of a linear equivalent model for a non-linear system with impacts [PDF]

, 2012
Modal characteristics of non-linear system are typically studied through response to harmonic excitation and using various definitions of non-linear modes. However, few results are available for systems under broadband excitation.

A Two‐Step Procedure for Generating Domestic and Asymmetric Trade Costs When Data Are Scarce

International Journal of Finance &Economics, EarlyView.
ABSTRACT The practice of domestic trade cost measurement faces several challenges related to data quality, methodology and theory; but the major issue is that of data scarcity. Due to these facts, both domestic and asymmetric trade costs have been ignored despite being a feature of modern trade models.

Decoding Mental States in Social Cognition: Insights from Explainable Artificial Intelligence on HCP fMRI Data

Machine Learning and Knowledge Extraction
Artificial neural networks (ANNs) have been used for classification tasks involving functional magnetic resonance imaging (fMRI), though typically focusing only on fractions of the brain in the analysis. Recent work combined shallow neural networks (SNNs)

How do Generalized Linear Models (glms) Explain the Variation in Species Richness in Freshwater Ecosystems?

Revista de Gestão Social e Ambiental
Objective: Assessing, through ecological modeling, which environmental variables explain the species richness of fish in streams in southern Maranhão.   Theoretical framework: Ecological modeling techniques that correlate species abundance or richness as response variables with environmental predictors are used to predict the probability of species ...

Temperature and heat‐load exposure effects on preterm births: Insights from a population‐based study using distributed lag non‐linear models

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Preterm birth presents a substantial health, psychological, and economic burden worldwide. Environmental factors, including temperature fluctuations, are known to influence the risk of preterm birth. This study aimed to investigate the association between high temperatures and heat load and preterm births. Methods Using a time‐series

Genome‐wide association study and BSR‐seq identify nitrate reductase–related genes in rice landraces (Oryza sativa L.)

The Plant Genome
Nitrogen (N) is an essential nutrient for rice (Oryza sativa L.) growth and development. However, the lower nitrogen use efficiency (NUE) results in an N fertilizer surplus, which causes many environmental problems. In this study, genome‐wide association
