From Expansion to Erosion: The Global Trajectory of Judicial Independence, 1960–2018

open access: yesSociological Forum, EarlyView.
ABSTRACT Judicial independence expanded globally throughout the twentieth century, but this trajectory has recently come under pressure. In recent years, governments around the world have increasingly challenged judicial autonomy. This study unpacks this global reversal by analyzing data from 156 states between 1960 and 2018.

Who Holds the Power? Gendered Experiences of Involuntary Singlehood in the Age of Online Dating*

open access: yesSociological Inquiry, EarlyView.
Although singlehood is a desired lifestyle for an increasing number of heterosexual women and men, many are involuntarily single, struggling to find a partner. Meanwhile, popular debates about dating are sharply polarized along gendered lines. While “incels” see themselves as victims on a dating market ruled by women, relatively mainstreamed feminist ...

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

open access: yesExperimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

open access: yesExperimental Physiology, EarlyView.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

Hemigrammopetersius barnardi (Teleostei: Characiformes: Alestidae): a study of skeletal ontogeny and identification of homology for phylogenetic analysis

open access: yesVertebrate Anatomy, Morphology, Palaeontology
Members of Alestidae, a family of characiforms found in sub–Saharan Africa, have a wide range of adult body sizes. Because of this range of adult size, phylogenetic characters for the group may be difficult to distinguish from ontogenetic features ...

Modeling the Intermediate Flow Regime in Flow‐Compensated Intravoxel Incoherent Motion MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3476-3487, June 2026.
ABSTRACT Purpose The intravoxel incoherent motion (IVIM) model is commonly used to separate the effects of motion related to diffusion and blood microcirculation (perfusion) on the MR signal. Depending on the encoding time (T), it is possible to probe the different temporal regimes of blood motion, which resemble a ballistic flow at short T and a ...

Assessment of Optimal T1/T2‐Weighted Combinations for Myelin Sensitivity: Effects of Echo Time and Exponents

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3176-3186, June 2026.
ABSTRACT Purpose The aim of this study is to improve the traditional T1‐weighted (T1w) over T2‐weighted (T2w) ratio as a proxy for myelin by investigating the optimal T2w TE and combination of exponent‐weighted T1w and T2w images (T1wx1/T2wx2). Methods T1w and T2w Gradient And Spin Echo (GRASE) data were acquired from 14 volunteers, 6 of whom had a ...

FMRI Approaches to Mapping Cerebrovascular Reactivity: Comparison of Gradient Echo BOLD and Spin Echo BOLD With Arterial Spin Labeling

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3309-3321, June 2026.
ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...
