The aim of the present study was to evaluate empirically confusion matrices in device validation. We compared the confusion matrix method to linear regression and error indices in the validation of a device measuring feeding behaviour of dairy cattle. In addition, we studied how to extract additional information on classification errors with confusion probabilities. The data consisted of 12 h behaviour measurements from five dairy cows; feeding and other behaviour were detected simultaneously with a device and from video recordings...

Video review and scoring was used to evaluate the behaviors of nurses wearing N95 filtering face piece respirators while providing isolation care in a simulated patient care environment. This study yielded a detailed description of behaviors related to N95 respirator use in a health care setting. Developing a more robust and systematic behavior analysis tool for use in demonstration, simulation, and clinical care would allow for improved respiratory protection of health care workers.

For many reaction processes, such as catalysis, phase transformations, nanomaterial synthesis etc., nanoscale observations at high spatial (sub-nanometer) and temporal (millisecond) resolution are required to characterize and comprehend the underlying factors that favor one reaction over another. The combination of such spatial and temporal resolution (up to 600 µs), while rich in information, produces a large number of snapshots, each of which must be analyzed to obtain the structural (and thereby chemical) information...

BACKGROUND: Chronic rhinosinusitis (CRS) may be initiated by innately impaired host defense mechanisms that predispose the upper airways to infection. Recent evidence suggests tethering of submucosal gland mucus strands represents an inciting event within cystic fibrosis (CF) airways, occurring prior to onset of chronic infection. Submucosal gland hypertrophy and defective mucociliary clearance (MCC) are present in actively inflamed sinuses, but mucus strand velocity may also be affected as a secondary event, further contributing to chronic disease...

Pediatric hydrocephalus is characterized by an abnormal accumulation of cerebrospinal fluid (CSF) and is one of the most common congenital brain abnormalities. However, little is known about the molecular and cellular mechanisms regulating CSF flow in the developing brain. Through whole-genome sequencing analysis, we report that a homozygous splice site mutation in coiled-coil domain containing 39 (Ccdc39) is responsible for early postnatal hydrocephalus in the progressive hydrocephalus (prh) mouse mutant. Ccdc39 is selectively expressed in embryonic choroid plexus and ependymal cells on the medial wall of the forebrain ventricle, and the protein is localized to the axoneme of motile cilia...

OBJECTIVE: Epileptic spasms (ES) often become drug-resistant. To reveal the electrophysiological difference between children with ES (ES+) and without ES (ES-), we compared the occurrence rate (OR) of high-frequency oscillations (HFOs) and the modulation index (MI) of coupling between slow and fast oscillations. In ES+, we hypothesized that (1) pathological HFOs are more widely distributed and (2) slow oscillations show stronger coupling with pathological HFOs than in ES-. METHODS: We retrospectively reviewed 24 children with drug-resistant multilobar onset epilepsy, who underwent intracranial video electroencephalography prior to multilobar resections...

BACKGROUND: Patent ductus arteriosus (PDA) occurs more frequently in premature infants. Depending on the degree of prematurity, these children often have other serious comorbidities that could significantly impact on surgical outcome. AIM: This study aimed to evaluate clinical results of the surgical ligation of PDA in extremely low body weight preterm infants with birth weight below 750 grams and to identify risk factors of mortality. METHODS: A total of 31 preterm infants with birth weight below 750 grams and significant PDA were operated between 2006 and 2016 through posterolateral thoracotomy (n=16) or with the use of video-assisted thoracoscopic (VATS) method (n = 15)...
