BrainCast: A spatio-temporal forecasting model for whole-brain fMRI time series prediction

Yunlong Gao · Jinbo Yang · Li Xiao · Haiye Huo · y 4 más

Functional magnetic resonance imaging (fMRI) enables noninvasive investigation of brain function, while short clinical scan durations, arising from human and non-human factors, usually lead to reduced data quality and limited statistical power for neuroimaging research. In this paper, we propose BrainCast, a novel spat...

Long time behavior of a class of non-homogeneous anisotropic fully nonlinear curvature flows

Weimin Sheng · Jiazhuo Yang

In this paper, we study a class of non-homogeneous anisotropic fully nonlinear curvature flows in $\mathbb{R}^{n+1}$. More precisely, we consider a hypersurface $M$ in $\mathbb{R}^{n+1}$ deformed by a flow along its unit normal with its speed $f(r)σ_k^α$ where $σ_k$ is the $k$-th elementary symmetric polynomial of $M$'...

Measurement of orientational correlated disorder resulting from in-plane rotations of fluorinated buckybowls

Quentin GUEROULT · Daniel CHANEY · Nimrod BENSHALOM · Florence ELLARY · y 1 más

We propose to study the orientational correlations in four molecular fluorinated variations of sumanene. Diffuse scattering (DS) will be used to elucidate the correlations in the disordered dipoles associated with the position of the substituted fluorine. We will study the temperature and field dependence of these corr...

From transient shocks to unexpected outcomes: Disruptive drivers in scenario pathways

Ross, Andrew

Scenario pathways (e.g. for the energy transition) often use a single trajectory or a band. That is not sufficient when one needs to understand why outcomes differ and under what stress or uncertainty they arise. Doing so requires tracking disequilibrium along pathways, comparing runs across "worlds" or storylines, and...

Functional reorganization after traumatic brain injury: A group ICA-based resting-state fMRI study in a porcine model

Ishfaque, Ahmed · Morgan H, LaBalle · Moira F, Taber · Sydney E, Sneed · y 3 más

Traumatic brain injury (TBI) is a serious health concern in the United States and worldwide. Understanding the mechanisms underlying resting-state functional activity can play an important role in profiling induced disruptions, potentially enabling accurate and timely interventions. Due to its homology to the human bra...

Cryo-XRF study of platinum-based O2 nanosensors internalized within microalgal cells

Karim BENZERARA · Murielle SALOME · Hélène MERCERON · Francois GUYOT · y 1 más

Assessing intracellular O2 resolved spatially and temporally in the fundamentally and biotechnologically important microalgae Chlamydomonas reinharditii is crucial for understanding their physiology. We developed a luminescent sensor for O2 made of a platinum complex-labelled polymeric nanoparticle which is successfull...

A MANOVA statistic for increasing number of samples

Ahmad, M. Rauf · Ahmed, Ejaz

A statistic to test MANOVA hypothesis is proposed for increasing number of independent samples. The statistic, defined as linear combination of U-statistics, is robust to normality and homoscedasticity assumptions, and can be used for balanced or unbalanced models. Whereas the focus is on the number of samples to be la...

Nursing students' critical engagement with generative AI in evidence-based practice education: A qualitative descriptive study

Ashlyn, Sahay · Adeniyi, Adeleye · Katrina, Lane-Krebs

The rapid integration of generative artificial intelligence (GenAI) into nursing education presents both opportunities and challenges, yet empirical evidence on students' critical engagement with AI-generated content within assessment contexts remains limited.To examine undergraduate nursing students' reflections when...

Information avoidance and overvaluation in sequential decision making under epistemic constraints

Shuo Li · Matteo Pozzi

Decision makers involved in the management of civil assets and systems usually take actions under constraints imposed by societal regulations. Some of these constraints are related to epistemic quantities, as the probability of failure events and the corresponding risks. Sensors and inspectors can provide useful inform...
