Theory and theoretical framework use for engineering education research: A systematic review of undergraduate disability research in the United States

Abstract Background Use of theory is a quality marker in engineering education research. However, it can be challenging to select an appropriate theoretical framework and explicate how that framework was used. Purpose Using undergraduate STEM disability research as an example, th...

Manganese transport, homeostasis, and neurotoxicity

Manganese (Mn) is an essential metal required for many physiological functions, and deficiency or over-exposure is associated with neurological dysfunction and neuropathology. Tight homeostatic control of Mn in the body is required to maintain optimal physiological levels and pro...

Allosterically Controlled Capture of Mutually Repulsive Guests With Positive Cooperativity and Ultrahigh Affinity

ABSTRACT A hexacationic cage incorporating three urea units can encapsulate two mutually repulsive anions in close proximity through a combination of hydrogen bonding and electrostatic interactions. This leads to exceptionally high binding affinities, with a K 1 × K 2 value of ap...

High-Voltage Sodium–MetalBatteries with AsymmetricFluoroalkoxylated Organoborate Anion Chemistry

Abstract The high reactivity of sodium (Na) metal restricts its compatibility to ether-based electrolytes, while the poor oxidative stability of ethers precludes their coupling to high-voltage cathodes, fundamentally limiting the operating voltage and energy density of sodium–met...

Ribosomal protein bL27 protects translating ribosomes from tmRNA-SmpB

Bacterial ribosomal protein bL27 is universally conserved, and its amino terminus is adjacent to the peptidyl transfer center, yet its roles in translation remain unclear. Combining genetics, biochemistry, and molecular dynamics, we show that bL27 has an unexpected role in preven...

Breaking Ghalib, Saving Urdu

Abstract No critic of Ghalib has acquired greater notoriety than Yas Yaganah Changezi, known in Urdu speaking circles as Ġhālib shikan, the “Ghalib breaker”—a title earned through his scathing critiques of Ghalib and everything the dominant Urdu milieu held sacred. For Yaganah, t...

Hydration-dependent exciton-phonon coupling in a metal-organic framework photocatalyst

Abstract Metal-organic frameworks (MOFs) have potential for light-harvesting applications owing to their tunable optoelectronic properties via building block selection. The presence of bound solvent in MOFs is known to impact gas adsorption properties, but little is known about t...

Optimal Operation of Gas Turbine Generator and Energy Storage for Islanded Microgrid AI Data Centers Under Workload Dynamics

The rapid growth of artificial intelligence (AI) data centers introduces highly variable and mission-critical load profiles that challenge conventional power supply strategies. This paper proposes an islanded microgrid gas turbine generator (GTG) and long-duration energy storage...

Effect of time to palliative epilepsy surgery on outcomes

Abstract Objective Epilepsy duration is a modifiable risk factor in the outcome of definitive epilepsy surgery; however, an analogous effect in palliative procedures has not been shown. We reviewed the Pediatric Epilepsy Surgery Database data for an association between epilepsy d...

The Weight of the Number: Perceptions and Practices Surrounding Expected Body Weight Disclosure in Eating Disorder Treatment

ABSTRACT Objective Expected body weight (EBW) determination is common in eating disorder (ED) treatment, yet no evidence‐based guidelines exist for how to discuss EBWs with patients. Clinicians have previously conceptualized these discussions as therapeutic exposures targeting fe...

Plants, soil, and coexistence: an alternative approach to modelling plant-soil feedback

Abstract Background and Aims Plant-soil feedback (PSF) affects plant coexistence and diversity. Although the current paradigm provides a direct experimental method to quantify PSF and explains coexistence with varying levels of success, the emphasis on pairwise interactions hinde...

Ribo-ITP enables identification of translons from limited input samples

In the last decade, an unexpectedly large number of translated regions (translons) have been discovered using ribosome profiling and proteomics. Translons can act as regulatory elements or encode functional micropeptides. However, identification of translons has been limited to c...
