Thermal Error Modeling and Compensation for a Motorized Spindle of a Large CNC Gear Profile Grinding Machine Tool

IEEE Access
To address thermally induced errors in a motorized spindle during the grinding process of a large computer numerical control (CNC) gear profile grinding machine tool, a thermal error modeling method based on the partial least squares (PLS) method was ...

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

Journal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

How Mental Concepts Shape Sleep: Introducing the Mental Concept Reactivation Hypothesis of Sleep

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep problems affect a substantial proportion of individuals, and negative thoughts, rumination, and worry are considered key factors underlying persistence and severity. While extensive research has examined how these states disrupt sleep before falling asleep, much less is known about how mental concepts, including thoughts, expectations ...

A Double‐Blind Randomised Controlled Crossover Trial of the Effect of Blue‐Enriched Ambient Light on Sleep in Older Adults With Sleep Disturbance: The CleverLights Study

Journal of Sleep Research, EarlyView.
ABSTRACT Light interventions have been investigated for treating sleep disturbances in older adults; however, findings are mixed. This proof‐of‐concept trial investigated the effect of blue‐enriched ambient light on electroencephalographic (EEG) sleep in older adults with self‐reported poor sleep.

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Hypoxia and the cytoskeleton

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.
