Definition and identification of causal ratio effects.

In generalized linear models, the effect of a treatment or intervention is often expressed as a ratio (e.g., risk ratio and odds ratio).

Stimulus-induced rotary saturation imaging of visually evoked response: A pilot study.

Spin-lock (SL) pulses have been proposed to directly detect neuronal activity otherwise inaccessible through standard functional magnetic resonance imaging. However, the practical limits of this technique remain unexplored. Key challenges in SL-based detection include ultra-weak signal variations, sensitivity to magnetic field inhomogeneities, and potential contamination from blood oxygen level-dependent effects, all of which hinder the reliable isolation of neuronal signals.

Defects or no defects? Or how to design 20-25 nm spherical iron oxide nanoparticles to harness both magnetic hyperthermia and photothermia.

Designing iron oxide nanoparticles (IONPs) to effectively combine magnetic hyperthermia (MH) and photothermia (PTT) in one IONP formulation presents a significant challenge to ensure a multimodal therapy allowing the adaptation of the treatment to each patient. Recent research has highlighted the influence of factors such as the size, shape, and amount of defects on both therapeutic approaches. In this study, 20-25 nm spherical IONPs with a spinel composition were synthesized by adapting the protocol of the thermal decomposition method to control the amount of defects.

Interactions between latent variables in count regression models.

In psychology and the social sciences, researchers often model count outcome variables accounting for latent predictors and their interactions. Even though neglecting measurement error in such count regression models (e.g.

Tailoring the pore structure of iron oxide core@stellate mesoporous silica shell nanocomposites: effects on MRI and magnetic hyperthermia properties and applicability to anti-cancer therapies.

Core-shell nanocomposites made of iron oxide core (IO NPs) coated with mesoporous silica (MS) shells are promising theranostic agents. While the core is being used as an efficient heating nanoagent under alternating magnetic field (AMF) and near infra-red (NIR) light and as a suitable contrast agent for magnetic resonance imaging (MRI), the MS shell is particularly relevant to ensure colloidal stability in a biological buffer and to transport a variety of therapeutics. However, a major challenge with such inorganic nanostructures is the design of adjustable silica structures, especially with tunable large pores which would be useful, for instance, for the delivery of large therapeutic biomolecule loading and further sustained release.
