Capabilities of noninvasive dosimeters for radiation monitoring of parameters of X-ray diagnostic apparatuses are considered. It is shown that monitoring of the half-value layer using the Unfors-Xi detector makes it possible to correct the results of radiation contrast measurement taking into account the actual (measured) values of half-value layers. It also simplifies the procedure for half-value layer monitoring in radiation safety measurements.

Background: Intrabdominal pressure (IAP) is an important parameter. Elevated IAP can reduce visceral perfusion, lead to intraabdominal hypertension, and result in life-threatening abdominal compartment syndrome. While ingestible capsular devices have been used for various abdominal diagnoses, their application in continuous IAP monitoring remains unproven.

Noninvasive methods for intracranial pressure (ICP) monitoring have emerged, but none has successfully replaced invasive techniques. This observational study developed and tested a machine learning (ML) model to estimate ICP using waveforms from a cranial extensometer device (brain4care [B4C] System). The model explored multiple waveform parameters to optimize mean ICP estimation.

Remaining useful life (RUL) prediction is a crucial aspect of the prognostics health management of lithium-ion batteries (LIBs). Owing to the influence of resampling technology, particle degradation is often observed in the particle filter-based RUL prediction of LIBs, resulting in a low prediction accuracy and large uncertainty. In this paper, a novel particle flow filter with the grey model method (GM-PFF) is proposed to forecast the RUL and state of health of batteries.

Background: Patients with typical reflux symptoms and normal acid exposure time (AET) are classified as either reflux hypersensitivity (RH) or functional heartburn (FH), some of whom respond to proton pump inhibitors (PPIs). We determined if esophageal psychophysiological parameters predict PPI response in symptomatic RH and FH patients.
Methods: We prospectively recruited adults with heartburn diagnosed with RH or FH on 24-h impedance-pH monitoring off PPI.

Three French harbours connected to different water masses of the English Channel were chosen to investigate the hydrological parameters, chemical contaminants, and biofouling characteristics for 15 months. The biofouling development on two kinds of coatings, an anticorrosion coating (Epoxy) and a foul-release coating (FRC), was studied to compare micro- and macro- biofouling in harbour environments. Biofouling was investigated by considering wet biofouling biomass and composition, microalgae concentration, and bacterial abundance.
