Multiple Video Frame Interpolation via Enhanced Deformable Separable Convolution.

IEEE Trans Pattern Anal Mach Intell 2021 Jul 29;PP. Epub 2021 Jul 29.

Generating non-existing frames from a consecutive video sequence has been an interesting and challenging problem. Recent kernel-based interpolation methods predict pixels with a single convolution process that convolves source frames with spatially adaptive local kernels. However, when scene motion is larger than the pre-defined kernel size, these methods are prone to yield less plausible results and they cannot directly generate a frame at an arbitrary temporal position because the learned kernels are tied to the midpoint in time between the input frames.

Magnetic Field Mapping and Correction for Moving OP-MEG.

IEEE Trans Biomed Eng 2021 Jul 29;PP. Epub 2021 Jul 29.

Background: Optically pumped magnetometers (OPMs) have made moving, wearable magnetoencephalography (MEG) possible. The OPMs typically used for MEG require a low background magnetic field to operate, which is achieved using both passive and active magnetic shielding. However, the background magnetic field is never truly zero Tesla, and so the field at each of the OPMs changes as the participant moves. Read More

Learning embedding features based on multi-sense-scaled attention architecture to improve the predictive performance of anticancer peptides.

Bioinformatics 2021 Jul 29. Epub 2021 Jul 29.

School of Software, Shandong University, Jinan, China.

Motivation: Anticancer peptides (ACPs) have recently emerged as effective anticancer drugs in cancer therapy. Machine-learning-based predictors have been developed to identify ACPs and achieve satisfactory performance. However, existing methods suffer from experience-based feature engineering, which not only restricts the representation ability of the models to a certain extent but also lacks adaptivity for different data, limiting the further improvement of the predictive performance and impacting the robustness of the predictive models.

Visualizing Trace Pollutants in Solids at Nanoscale via Electron Tomography.

Environ Sci Technol 2021 Jul 29. Epub 2021 Jul 29.

State Key Laboratory for Pollution Control and Resource Reuse, College of Environmental Science and Engineering, Tongji University, Shanghai Institute of Pollution Control and Ecological Security, Shanghai 200092, China.

Visualizing trace pollutants such as toxic metals and viruses in environmental solids such as soils, sediments, aerosols, and suspended particles in water has long been the holy grail for scientists and engineers. In this Perspective, progress on the state-of-the-art electron tomography is highlighted as an increasingly indispensable tool for visualizing contaminant distribution and transformation in three-dimension (3D), including environmental pollutants at the water-minerals interfaces, toxicology assessment, environmental behavior of viruses in heterogeneous environmental media, etc. Adding a third dimension to the pollutant characterization will surely enrich our understanding on the complex and emerging environmental issues facing the global society, and provide vital support to the ongoing research and development of life-saving mitigation technologies from air filtration, to drinking water purification, to virus disinfection.

Automated segmentation of deep brain nuclei using convolutional neural networks and susceptibility weighted imaging.

Hum Brain Mapp 2021 Jul 29. Epub 2021 Jul 29.

Department of Neurology, Medical University of Innsbruck, Innsbruck, Austria.

The advent of susceptibility-sensitive MRI techniques, such as susceptibility weighted imaging (SWI), has enabled accurate in vivo visualization and quantification of iron deposition within the human brain. Although previous approaches have been introduced to segment iron-rich brain regions, such as the substantia nigra, subthalamic nucleus, red nucleus, and dentate nucleus, these methods are largely unavailable and manual annotation remains the most used approach to label these regions. Furthermore, given their recent success in outperforming other segmentation approaches, convolutional neural networks (CNN) promise better performances. Read More

The prevalence of SARS-CoV-2 antibodies in triage-negative patients and staff of a fertility setting from lockdown release throughout 2020.

Hum Reprod Open 2021 27;2021(3):hoab028. Epub 2021 Jul 27.

Department of Obstetrics and Gynecology, 'Carol Davila' University of Medicine and Pharmacy, Bucharest, Romania.

Study Question: What is the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in triage-negative patients undergoing ART and fertility care providers after lockdown release and throughout 2020?

Summary Answer: Out of the triage-negative patients whose blood samples were assessed for SARS-CoV-2 antibodies over 6 months, 5.2% yielded positive results with a significantly higher rate in health care workers (HCWs) and a significant month-by-month increase in those with evidence of antibodies.

What Is Known Already: Patients of reproductive age are more prone to asymptomatic or minimal forms of coronavirus disease 2019 (COVID-19) as compared to older age groups, and the identification of those with active infection and those already exposed (and probably immunized) is important for safety and cost-effective use of testing resources in the fertility setting.
