Article Abstract
To meet the stringent requirements for sub-nanometer surface roughness and full-spectrum spatial frequency error control in high-precision optical systems, this study systematically investigates the effects of varying Cerium oxide (CeO) abrasive particle sizes and pitch pad hardness on the surface quality of fused silica glass during computer-controlled optical surfacing (CCOS). This study integrates experimental characterization with mathematical modeling to analyze the mechanisms by which abrasive particle size and polishing tool hardness influence material removal rates, contact pressure distribution, and surface roughness. The results indicate that smaller CeO particles effectively reduce high-spatial frequency roughness, making them suitable for precise micro-surface finishing, while larger particles exhibit higher material removal efficiency, making them more suitable for macro-surface machining. Hard pitch pads induce greater indentation depth and concentrated pressure, significantly improving mid-spatial frequency surface errors, while softer pitch pads are more suitable for overall surface smoothing. Experimental findings further validate the feasibility and effectiveness of the proposed optimization strategies in achieving ultra-precision processing at picometer scales across the full spectrum of frequency bands. This study provides a theoretical basis and practical guidance for selecting process parameters in the manufacturing of high-precision optical components.

Background: Current management of pediatric cutaneous abscesses involves either spontaneous healing by secondary intention or suturing through tertiary intention, which are often lengthy processes that cause discomfort and distress among children. As it is noninvasive and simple, a novel zipper device is widely used for the primary wound closure of surgical incisions.
Objective: To describe the effectiveness of novel zipper device use for pediatric cutaneous abscess wound closure in an outpatient context.

Background And Objectives: The US Food and Drug Administration guidance for cold-stored platelets (CSPs) permits storage of apheresis platelets at 1-6°C for ≤14 days. During a pilot programme, CSPs were evaluated in a large US blood centre over a 10-month period (September 2023 to July 2024) to better understand the formation of aggregates under routine use.
Materials And Methods: Platelets collected in 100% plasma were moved into cold storage within 4 h of collection and shipped to local hospitals.

This study presents a renewable electricity-driven microbial electrosynthesis (MES) system integrated with biological nitrogen removal (BNR) to achieve carbon-negative wastewater treatment. The MES system converts CO₂ into acetate, which is directly utilized as an internal carbon source for denitrification. Incorporation of biochar-derived conductive materials enhanced electron transfer, increasing acetate productivity to 1.
