River networks are the major pathways for microplastic (MP) transport from terrestrial environments to oceans. It is essential to understand where MPs reside and how they move along river networks because of their potential to negatively impact ecosystems. However, the ability to quantify the water-sediment exchange of MPs, locations of deposition, and the time scales over which burial occurs is limited.

Article Synopsis
  • The study aimed to determine if using a continuous non-invasive pCO monitor in extremely low birth weight (ELBW) infants during their first week of life could reduce rates of severe brain injuries (IVH or PVL) and related mortality.
  • A total of 132 ELBW infants were observed, divided into a study group monitored by the TCpCO and a smaller control group due to monitor availability, showing no significant difference in rates of IVH/PVL or combined outcomes between the two groups.
  • The research highlighted difficulties in conducting controlled trials in fast-evolving medical practices, as changes in standard care complicated the study's findings and limited the ability to make strong conclusions.

Unlabelled: Computational methods have been established as cornerstones in optical imaging and holography in recent years. Every year, the dependence of optical imaging and holography on computational methods is increasing significantly to the extent that optical methods and components are being completely and efficiently replaced with computational methods at low cost. This roadmap reviews the current scenario in four major areas namely incoherent digital holography, quantitative phase imaging, imaging through scattering layers, and super-resolution imaging.

More than half of the world's rivers dry up periodically, but our understanding of the biological communities in dry riverbeds remains limited. Specifically, the roles of dispersal, environmental filtering and biotic interactions in driving biodiversity in dry rivers are poorly understood. Here, we conduct a large-scale coordinated survey of patterns and drivers of biodiversity in dry riverbeds.

  • Extremely low birth weight (ELBW) premature infants are at high risk for both low and high carbon dioxide levels, which can lead to serious health issues.
  • A study was conducted to compare CO levels from non-invasive transcutaneous monitors (TcCO) with traditional blood gas measurements (bgCO) in ELBW infants, finding a moderate correlation and good agreement between the two methods.
  • Results indicate that while TcCO can effectively monitor CO levels in these infants, it should be used alongside blood gas sampling for a comprehensive assessment due to variability in readings.

  • The velocity time integral (VTI) is a Doppler ultrasound measurement used to evaluate blood flow, specifically looking at the middle cerebral artery (MCA) in fetuses affected by maternal alloimmunization.
  • This study analyzed 255 Doppler examinations across different gestational weeks and found that VTI increases as pregnancy progresses, with significant differences in values when comparing fetuses with suspected anemia to those without.
  • The findings suggest that higher VTI in fetuses may indicate increased blood flow to the brain, potentially serving as a new marker for detecting fetal anemia.

Imaging through highly scattering media is a challenging problem with numerous applications in biomedical and remote-sensing fields. Existing methods that use analytical or deep learning tools are limited by simplified forward models or a requirement for prior physical knowledge, resulting in blurry images or a need for large training databases. To address these limitations, we propose a hybrid scheme called Hybrid-DOT that combines analytically derived image estimates with a deep learning network.

Diffuse optical tomography (DOT) is a non-invasive method for detecting breast cancer; however, it struggles to produce high-quality images due to the complexity of scattered light and the limitations of traditional image reconstruction algorithms. These algorithms can be affected by boundary conditions and have a low imaging accuracy, a shallow imaging depth, a long computation time, and a high signal-to-noise ratio. However, machine learning can potentially improve the performance of DOT by being better equipped to solve inverse problems, perform regression, classify medical images, and reconstruct biomedical images.
