Summary: Protein glycosylation is a crucial process that enhances protein diversity and adaptability. Accurate quantification of glycosylation is essential to observe changes and impacts during biological processes. Researchers need to focus on the distribution of glycosylation sites and analyze them using appropriate bioinformatics algorithms.

Summary: This paper presents a framework for robust extraction of the charge radii of protons and deuterons from PRad data, discussing methods for finding the best fitter candidates and testing the extraction procedure based on elastic electron-deuteron scattering data. The proposed method for extracting the deuteron charge radius in the low-Q(2) DRad experiment at Jefferson Lab can be further improved with more data.

Summary: Cryogenic electron tomography (cryoET) is a powerful method for studying the 3D structure of biological samples, but it requires a large number of tilt series with high maintenance costs. Recent implementations improve the efficiency of grid screening and large-scale tilt series data collection significantly.

Summary: The paper introduces an efficient approach for high quality GPU-based rendering of line data with ambient occlusion and transparency effects. By utilizing GPU-based raycasting of rounded cones and efficient voxel cone tracing approach, the method achieves high-quality rendering of complex line data. A new fragment visibility sorting strategy and hierarchical opacity maps are proposed to improve performance.

Summary: This study reports the results of a Monte Carlo global QCD analysis, utilizing constraints from the MARATHON experiment at Jefferson Lab for the first time. The analysis revealed indications of an isovector nuclear EMC effect in light nuclei in the simultaneous study of nucleon PDFs and nuclear effects in A = 2 and A = 3 nuclei. The MARATHON data provided relatively weak constraints on certain structure function ratios and PDF ratios, but raised questions about assumptions commonly made in nuclear PDF analyses by suggesting an enhanced nuclear effect on the d-quark PDF in the bound proton.

Summary: This study developed a tracing method for a scanning electron microscope based on a heterodyne interferometer, which traces the measured values to the laser wavelength and then to the internationally defined meter length reference, proving it as an absolute measurement method. Experimental results showed that this method effectively obtains the performance parameters of the feature size intuitively and significantly improves the measurement accuracy.

Summary: Single atom electrocatalysts (SAEs) show great promise for promoting important reactions, but direct probing of individual metal atom sites at the atomic scale is necessary to accelerate design and synthesis of improved SAEs. In this study, multiple individual SAE metal sites were mapped using direct electron detection electron energy-loss spectroscopy (EELS), and an automated method for identification and simultaneous acquisition of EELS and energy dispersive X-ray spectroscopic (EDS) signals was demonstrated. These techniques provide enhanced access to the local elemental and chemical environment of SAE metal site structures, improving our understanding of these electrocatalysts and accelerating their development.

Summary: The ultrastructure of spermatozoa of Javaen barb fish (S. orphoides) was studied using transmission and scanning electron microscopy. The spermatozoa of S. orphoides are relatively simple cells composed of a spherical head, a short midpiece, and a flagellum. The ultrastructure analysis showed the absence of acrosome, the total length of spermatozoa, and the specific organelles present. This study provides important information for understanding the reproductive biology and conservation of S. orphoides.
