We develop convergence acceleration procedures that enable a gradient descent-type iteration method to efficiently simulate Hartree-Fock equations for many particles interacting both with each other and with an external potential. Our development focuses on three aspects: (i) optimization of a parameter in the preconditioning operator; (ii) adoption of a technique that eliminates the slowest-decaying mode to the case of many equations (describing many particles); and (iii) a novel extension of the above technique that allows one to eliminate multiple modes simultaneously. We illustrate performance of the numerical method for the two-dimensional model of the first layer of helium atoms above a graphene sheet.

Article Synopsis
  • Pediatric patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) face risks related to their nutritional status, specifically body mass index (BMI), which affects transplantation success.
  • A study analyzed BMI data from patients treated between 2003 and 2023 and found that underweight patients had significantly lower survival rates and higher complications compared to those with normal or higher BMI.
  • The research emphasizes the need for regular nutritional assessment before and after transplant to improve outcomes, suggesting that BMI should be closely monitored to manage risks effectively.

In the present study, low molecular weight cyclic polyglycidol is used as a macroinitiator for hypergrafting glycidol and producing cyclic graft hyperbranched polyglycerol (cPG-g-hbPG) in the molecular weight range of 10-10 g mol. Linear graft hyperbranched polyglycerol (linPG-g-hbPG) and hyperbranched polyglycerol (hbPG) are prepared as reference samples. This creates a family of hbPG structures with cyclic, linear, and star cores, allowing to evaluate their properties in solution and in bulk.

Article Synopsis
  • Curcumin, found in turmeric, has strong anti-inflammatory, antioxidant, and antimicrobial properties that could help treat conditions like arthritis and cancer, but its effectiveness is hindered by poor bioavailability.
  • Recent research is exploring ways to enhance curcumin delivery using advanced materials like nanoparticles and liposomes, with a focus on laponite, a synthetic nanoclay that improves curcumin's stability and delivery due to its unique properties.
  • This study investigates how curcumin-laponite nanoparticles can effectively deliver curcumin to cell membranes, using various high-tech methods to monitor their interaction, ultimately aiming to develop targeted therapies for diseases such as cardiovascular issues, neurological disorders, and cancer.

Article Synopsis
  • * A method called HPLC-UV was employed to assess the chemical stability, confirming that most storage conditions maintained the medication's concentration within acceptable limits.
  • * The study found that glycopyrrolate remains stable for at least 210 days at room temperature or 4 °C in different types of containers, except for glass at 45 °C, ensuring safety and quality for pediatric use.
