Conference paper (peer-reviewed)abstract
- The Visual Object Tracking challenge VOT2021 is the ninth annual tracker benchmarking activity organized by the VOT initiative. Results of 71 trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in recent years. The VOT2021 challenge was composed of four sub-challenges focusing on different tracking domains: (i) VOT-ST2021 challenge focused on short-term tracking in RGB, (ii) VOT-RT2021 challenge focused on "real-time" short-term tracking in RGB, (iii) VOT-LT2021 focused on long-term tracking, namely coping with target disappearance and reappearance and (iv) VOT-RGBD2021 challenge focused on long-term tracking in RGB and depth imagery. The VOT-ST2021 dataset was refreshed, while VOT-RGBD2021 introduces a training dataset and sequestered dataset for winner identification. The source code for most of the trackers, the datasets, the evaluation kit and the results along with the source code for most trackers are publicly available at the challenge website(1).

Robust estimation of bacterial cell count from optical density

Journal article (peer-reviewed)abstract
- Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data.

Mo-O-Bi Bonds as interfacial electron transport bridges to fuel CO2 photoreduction via in-situ reconstruction of black Bi2MoO6/ BiO2-x heterojunction
- 2022

Journal article (peer-reviewed)abstract
- High photogenerated carrier separation efficiency plays a crucial role in determining the rate of photocatalytic CO2 reduction, but the directional transfer of carrier remains challenging. Here, improved CO2 photoreduction rate and enhanced stability were realized by in-situ construction of BiO2-x nanoparticles on Bi2MoO6 nanoflowers using H2/Ar low temperature plasma. As evidenced by DFT calculations and photocurrent measurements, the Mo-O-Bi bonds between the Bi2MoO6 and BiO2-x interfaces act as a charge transport bridge, facilitating the directional transport of electrons and thus enhancing the rate of photocatalytic reduction reactions involving multiple electrons. Compared with pristine Bi2MoO6, Bi2MoO6/BiO2-x heterojunction has excellent photostability (12 h) and efficient photocatalytic activity (approximate to 3.0 times). This indicates that the charge transfer bridge can effectively inhibit the charge recombination and deactivation of pristine Bi2MoO6. This interatomic charge transfer bridges mode can not only solve the stability problem of bismuth-based materials, but also help to design more photocatalytic systems for efficient reduction of CO2.
