Faculty of Environmental Sciences and Natural Resource Management, Norwegian University of Life Sciences (NMBU), 1433 Ås, Norway; Norwegian Geotechnical Institute (NGI), 0484 Oslo, Norway. Electronic address:

Article Synopsis
  • A study was conducted to investigate how well different types of biochar can absorb perfluorooctanoic acid (PFOA), a harmful PFAS compound, comparing 23 diverse biochars made from materials like sewage sludge and wood waste.
  • The research assessed the biochars' properties such as surface area, pore size, and chemical composition, revealing that sludge-based biochars were significantly more effective at capturing PFOA than wood-based ones.
  • Statistical analysis indicated that the ability to adsorb PFOA was largely determined by the biochars' pore volume and the presence of hydrophobic interactions due to their aromatic carbon content.

Article Synopsis
  • Children with ADHD often face sleep issues, which are linked to higher rates of internalizing problems like depression and anxiety.
  • In a study of 188 children with ADHD, 59% reported sleep problems, and those with these issues were less physically active and experienced higher internalizing symptoms.
  • The findings suggest that improving sleep and physical activity could be vital for reducing depression and anxiety in children with ADHD, highlighting the need for future research on these relationships.

Article Synopsis
  • A study called PEERLESS compared two catheter methods, large-bore mechanical thrombectomy (LBMT) and catheter-directed thrombolysis (CDT), for treating intermediate-risk pulmonary embolism (PE) in 550 patients, focusing on various health outcomes.
  • The results showed that LBMT led to fewer complications and less need for intensive care compared to CDT, including lower rates of clinical deterioration and ICU admissions.
  • Although LBMT had better short-term outcomes, there were no significant differences in mortality or major bleeding between the two treatment methods after 30 days.

Objective:  This study aimed to externally validate the Preeclampsia Integrated Estimate of Risk (fullPIERS) risk prediction model in a cohort of pregnant individuals with preeclampsia in the United States.

Study Design:  This was a retrospective study of individuals with preeclampsia who delivered at 22 weeks or greater from January 1, 2010, to December 31, 2020. The primary outcome was a composite of maternal mortality or other serious complications of preeclampsia occurring within 48 hours of admission.

Context: Chronic ankle instability (CAI) is associated with motor-behavioral and sensory-perceptual impairments, including reduced balance performance, hip strength, and ankle function, and increased disablement, and injury-related fear. Progressive balance training (BAL) and hip strengthening (HIP) can both improve balance and function, but their comparative effects are unknown. Our objective was to compare the effects of progressive BAL and HIP on balance, hip strength, and patient-reported outcomes in those with CAI.

The purpose of this study is to investigate the effect of task constraints on the neurobiological systems while maintaining postural control under various sensory feedback manipulations in individuals with and without Chronic Ankle Instability (CAI). Forty-two physically active individuals, with and without CAI, were enrolled in a case-control study conducted at a biomechanics research laboratory. All participants underwent the Sensory Organization Test (SOT), which assesses individuals' ability to integrate somatosensory, visual, and vestibular feedback to maintain postural control in double-, uninjured-, and injured-limb stances under six different conditions in which variations in the sway-referenced support surface (platform) and visual surroundings, with and without vision, are manipulated to affect somatosensory and visual feedback.

Predictions of Lattice Parameters in NiTi High-Entropy Shape-Memory Alloys Using Different Machine Learning Models.

Materials (Basel)

September 2024

Department of Materials Science and Engineering, National Yang Ming Chiao Tung University, 1001 University Road, Hsinchu 30010, Taiwan.

This work applied three machine learning (ML) models-linear regression (LR), random forest (RF), and support vector regression (SVR)-to predict the lattice parameters of the monoclinic B19' phase in two distinct training datasets: previously published ZrO-based shape-memory ceramics (SMCs) and NiTi-based high-entropy shape-memory alloys (HESMAs). Our findings showed that LR provided the most accurate predictions for a, a, b, and c in NiTi-based HESMAs, while RF excelled in computing β for both datasets. SVR disclosed the largest deviation between the predicted and actual values of lattice parameters for both training datasets.
