Different from vehicle engines, Diesel Particulate Filter (DPF) inactivation is an unavoidable issue for low-speed marine diesel engines fueled with Heavy Fuel Oil (HFO). This paper introduced a sulfur resisting material in Silicon Carbide (SiC)-DPF to improve DPF performance. The results of bench-scale experiments showed that the Balance Point Temperature of the modified DPF module was 300°C and DPF modules had a good filtration performance, with Particulate Matters (PMs) residual being less than 0.6 g per cycle. In pilot-scale tests, PMs emissions of unit power decreased with engine load going up, filtration efficiency of nucleation mode PMs being only 36% under 100% load, while DPF still had a good performance in accumulation mode PMs control, being 94.2% under the same load. DPF modules showed excellent regeneration durability in the 205h endurance test, with a regeneration period of 1.5-2h under 380°C. There was no obvious degeneration in the DPF module structure, with no cracks or breakage. Besides, the DPF module could also control gaseous emissions, total emissions decreased by 10.53% for NO and 57.19% for CO, respectively. The results suggested that introducing sulfur-resisting material in DPF could greatly improve the DPF performance of low-speed marine diesel engines fueled with HFO.

Article Synopsis
- The development of efficient nanomaterials for the alkaline hydrogen oxidation reaction (HOR) is crucial for improving anion exchange membrane fuel cells (AEMFCs).
- Traditional Pt-based electrocatalysts face challenges like limited activity and CO poisoning due to difficulties in optimizing their surface interactions with hydrogen-related compounds.
- The new Ru/EuO@N-CNFs catalyst demonstrates significantly enhanced electrocatalytic performance for HOR, achieving 156.3 mA cm at 50 mV and stable operation for over 35,000 seconds, providing insights for creating more effective Ru-based materials.

Methodological improvements in cryo-electron microscopy (cryoEM) have made it a useful tool in ligand-bound structure determination for biology and drug design. However, determining the conformation and identity of bound ligands is still challenging at the resolutions typical for cryoEM. Automated methods can aid in ligand conformational modeling, but current ligand identification tools - developed for X-ray crystallography data - perform poorly at resolutions common for cryoEM.

Understanding the early stages of human congenital myopathies is critical for proposing strategies for improving musculoskeletal muscle performance, such as restoring the functional integrity of the cytoskeleton. SH3 and cysteine-rich domain 3 (STAC3) are proteins involved in nutrient regulation and are an essential component of the excitation-contraction (EC) coupling machinery for Ca releasing. A mutation in STAC3 causes debilitating Native American Myopathy (NAM) in humans, while loss of this gene in mice and zebrafish (ZF) results in premature death.

Most teleost fish propel themselves with lateral body waves powered by their axial muscles. These muscles also power suction feeding through rapid expansion of the mouth cavity. They consist of muscle segments (myomeres), separated by connective tissue sheets (myosepts).

Significance: Reference cerebral near-infrared spectroscopy (NIRS) data on the pediatric population are scarce, and in most cases, only cerebral oxygen saturation ( ) measured by continuous wave spatially resolved spectroscopy NIRS is reported. Absolute data for baseline optical and hemodynamic parameters are missing.
Aim: We aimed at collecting baseline cerebral optical parameters [absorption coefficient, ; reduced scattering coefficient, ; differential pathlength factor (DPF)] and hemodynamic parameters [oxy-hemoglobin content ( ), deoxyhemoglobin content (HHb), total hemoglobin content (tHB), ] in a large cohort of pediatric patients.
