A characterization of the $n$-ary many-sorted closure operators and a many-sorted Tarski irredundant basis theorem

open access: yes, 2017
A theorem of single-sorted algebra states that, for a closure space $(A,J)$ and a natural number $n$, the closure operator $J$ on the set $A$ is $n$-ary if, and only if, there exists a single-sorted signature $\Sigma$ and a $\Sigma$-algebra $\mathbf{A ...

Predictive factors for emergency cesarean section in grand multiparous compared to primiparous and multiparous women

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To identify predictive factors for emergency cesarean section (CS) in grand multiparous women and compare them with primiparous and multiparous women. Methods This was a retrospective cohort study in a single large university‐affiliated tertiary medical center between 2011 and 2018, analyzing all women with singleton pregnancies that

Mapping developmental transitions in mental health from mid‐ to late‐adolescence: Concurrent and longitudinal links to cognition

open access: yesJCPP Advances, EarlyView.
Abstract Background Developmental changes in mental health are mostly mapped between childhood and adolescence or childhood and adulthood. This study maps developmental transitions in mental health profiles from mid‐ to late‐adolescence, exploring how these transitions relate to cognitive function in mid‐adolescence. Method Participants from the IMAGEN

Leader Succession and Strategic Change: The Role of Leader's Subgroups Size

open access: yesStrategic Change, EarlyView.
ABSTRACT Research suggests that new CEO successors drive strategic change through the subgroup of their immediate collaborators. However, it remains unclear how this subgroup is configured. In this research, we address this limitation by introducing a new concept of “CEO's subgroup size” (the number of TMT members in the CEO's subgroup).

Esterification enhances carotenoid retention during bread‐making

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Carotenoids are plant‐derived antioxidants that contribute to human health and represent key quality traits in wheat‐based foods. However, they are highly unstable and prone to degradation during processing. Xanthophyll esterification has been identified as a natural mechanism that enhances carotenoid stability during grain storage.

Mid‐Infrared Quantum Scanning Microscopy via Visible Light Beyond Spatial Correlations

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces a raster‐scanning approach based on quantum imaging with undetected light (QIUL) that probes samples in the mid‐infrared (MIR) spectral range while performing detection in the visible domain. Unlike previous QIUL implementations, this technique operates independently of photon‐pair spatial correlations and relies solely on induced ...

Time‐Division Multiplexing for Parallel Transmission at Ultra‐High Field With Limited RF Channels

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Investigating time‐division multiplexing for parallel transmission in ultra high‐field imaging, striving for homogeneous whole brain excitation with a limited number of RF channels. Methods A fast RF switch was built to alternately route 8 transmit channels to each row of a double‐row 16‐element transmit coil array at a 9.4 T human MRI

Coaxial Dipole Array With Switching Transmit Sensitivities for Ultrahigh Field MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra‐high field MRI. Methods Reconfigurable dipole elements that could produce two distinct electronically switchable B1+$$ {B}_1^{+} $$ field profiles were conceptualized and constructed. Eight such elements were

Physiological barriers to oral intake in survivors of critical illness: A scoping review

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Oral nutrition is the predominant mode of nutrition delivery on the post–Intensive Care Unit (ICU) ward; yet, it is associated with lower intake than via enteral or parenteral nutrition. There are limited data on barriers that influence oral intake in ICU survivors.
