MPicker: visualizing and picking membrane proteins for cryo-electron tomography
Published 2025-01-01“…Abstract Advancements in cryo-electron tomography (cryoET) allow the structure of macromolecules to be determined in situ, which is crucial for studying membrane protein structures and their interactions in the cellular environment. However, membranes are often highly curved and have a strong contrast in cryoET tomograms, which masks the signals from membrane proteins. …”

pytom-match-pick: A tophat-transform constraint for automated classification in template matching
Published 2025-06-01“…We benchmarked pytom-match-pick on public datasets, demonstrating improved classification and localization of macromolecules like ribosomal subunits and proteasomes that led to fewer artifacts in subtomogram averages. This tool promises to advance visual proteomics by improving the efficiency and accuracy of macromolecule detection in cellular contexts.…”

Standards: Exposure Limits for Brief High Intensity Pulses of Radiofrequency Energy Between 6 and 300 GHz
Published 2025-01-01“…This Standards paper considers limits of the International Commission on Nonionizing Radiation (ICNIRP) and Institute of Electrical and Electronics Engineers (IEEE C95.1-2019) on “brief exposures” to radiofrequency energy (RF-EMF), that vary significantly within the 6 minute averaging time specified in the limits. This situation arises in two important contexts: exposures from cellular base stations employing Multiple Input Multiple Output (MIMO) antennas with beamforming that sweep beams around the service area, and exposure to pulsed RF-EMF with high peak power but low duty cycle. …”

Exploring Imaging Applications of a Red-Emitting π-Acceptor (π-A) Pyrene-Benzothiazolium Dye
Published 2024-12-01“…The optical properties of BTP are studied in intracellular environments through advanced fluorescence microscopy techniques, with BTP exhibiting a noticeable shift toward blue (λ<sub>em</sub> ≈ 590 nm) emissions in cellular lysosomes. The averaged photon arrival time (AAT)-based studies exhibit two different emissive populations of photons, indicating the probe’s dynamic equilibrium between two distinctively different lysosomal microenvironments. …”

Statistical data analysis methods in Brillouin spectroscopy: Tutorial
Published 2025-06-01“…Since the majority of subcellular and extracellular matrix components are significantly smaller than 1 μm, many cell and tissue components become averaged in a single imaging voxel. This, in turn, presents a challenge for data analysis of Brillouin microscopy measurements collected from heterogeneous samples, especially since the cellular components often have similar and closely positioned spectral features. …”

Analysis of Satellite and In Situ Optical Proxies for PIC and POC During GEOTRACES GP15 and GP17‐OCE Transects From the Subarctic North Pacific to the Southern Ocean
Published 2025-04-01“…South of the APF, both satellite and birefringence sensor greatly overestimated PIC by factors of >25 and 12, respectively, compared to sample PIC which averaged 15 nM. The unanticipated discovery of a non‐carbonate particle birefringence source coupled with a microscopic investigation of pump samples leads us to hypothesize that internal reflection within bubbles and/or cellular structures of heavily silicified colony‐forming diatoms (Fragilariopsis and Pseudo‐nitzschia) is the cause for anomalous birefringence and adds to backscattered satellite radiances.…”
