Renmin University researchers present a comprehensive survey of sampling- and sketch-based algorithms for distinct value estimation in big data, offering insights to accelerate database queries, enhance network security anomaly detection, and reduce cloud analytics costs.

Low carbon fuel policies are intended to reduce greenhouse gas (GHG) emissions from transportation. However, rigid carbon intensity (CI) accounting procedures in current policies may limit CI responsiveness across candidate sites and facilities. This study examines how low carbon fuel programs capture or overlook spatial variability and net electricity production in biofuel carbon intensity, influencing crediting outcomes and fuel selling prices.

A research team from the Wolfson Faculty of Chemical Engineering at the Technion – Israel Institute of Technology has developed biomimetic hydrogel bioadhesives that can seal wounds within seconds—eliminating the need for sutures or staples. Inspired by how mollusks adhere to wet surfaces, these PTLA bioadhesives offer strong, rapid adhesion even under wet or extreme conditions. The innovation, published in Advanced Materials, showed exceptional hemostasis and sealing performance in animal models, with potential applications in emergency medicine, minimally invasive surgery, and battlefield care.

Led by Dr. Shady Farah and Ph.D. student Qi Wu, the team has filed an international patent for the technology, which also demonstrates antimicrobial, antioxidant, and self-gelling properties—paving the way for next-generation wound care materials.
