Generative Bayesian Computation for Maximum Expected Utility.

Generative Bayesian Computation (GBC) methods are developed to provide an efficient computational solution for maximum expected utility (MEU). We propose a density-free generative method based on quantiles that naturally calculates expected utility as a marginal of posterior quantiles. Our approach uses a deep quantile neural estimator to directly simulate distributional utilities.

Repairing the Nasal Valve in Revision Surgery.

Nasal airway obstruction is a frequent complaint in an otolaryngology clinic and is often multifactorial. Anatomic contributors may include a nasal septal deviation, inferior turbinate hypertrophy, and nasal valve compromise. Septoplasty and inferior turbinate reduction are one of the most common procedures performed by an otolaryngologist.

Comparing quantity of marine debris to California horn shark sightings and egg appearances in Redondo Beach, California, USA.

Towards the automatic detection of activities of daily living using eye-movement and accelerometer data with neural networks.

Early diagnosis of neurodegenerative diseases, such as Alzheimer's disease, improves treatment and care outcomes for patients. Early signs of cognitive decline can be detected using functional scales, which are written records completed by a clinician or carer, detailing a patient's capability to perform routine activities of daily living. For example, tasks requiring planning, such as meal preparation, are some of the earliest affected by early mild cognitive impairment.

Targeted exonic sequencing identifies novel variants in a cerebral small vessel disease cohort.

Background And Aims: Cerebral small vessel diseases (CSVDs) are a set of conditions that affect the small blood vessels in the brain and can cause severe neurological pathologies such as stroke and vascular dementia. The most common monogenic CSVD is cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) which is caused by mutations in NOTCH3. However, only 15-20% of CADASIL cases referred for genetic testing have pathogenic mutations in NOTCH3.

Genomic identification, evolutionary analysis, and transcript profiling of protein phosphatase 2C in Solanum lycopersicum.

Protein phosphatases (PPs) are a class of enzymes that play a critical role in cellular regulation by catalyzing the removal of phosphate groups from proteins. This dephosphorylation process is essential for controlling and modulating various cellular functions, including signal transduction, cell cycle progression, metabolic regulation, and stress responses. This study focuses on the comprehensive genomic identification, evolutionary analysis, and transcript profiling of the PP2C gene family within Solanum lycopersicum, an economically significant crop with substantial agricultural and nutritional importance.

Data was collected from two prospective cohorts between 2005 and 2020 in Vancouver, Canada. Among 13,596 visits contributed by 1445 participants receiving OAT, we employed repeated measures latent class analysis using seven indicators and identified four longitudinal substance use classes.

How Can One Metal Power Nucleic Acid Phosphodiester Bond Cleavage by a Nuclease? Multiscale Computational Studies Highlight a Diverse Mechanistic Landscape.

Despite the remarkable resistance of the nucleic acid phosphodiester backbone to degradation affording genetic stability, the P-O bond must be broken during DNA repair and RNA metabolism, among many other critical cellular processes. Nucleases are powerful enzymes that can enhance the uncatalyzed rate of phosphodiester bond cleavage by up to ∼10-fold. Despite the most well accepted hydrolysis mechanism involving two metals (M to activate a water nucleophile and M to stabilize the leaving group), experimental evidence suggests that some nucleases can use a single metal to facilitate the chemical step, a controversial concept in the literature.
