Abstract: A computational cytometer operates using magnetically modulated lensless speckle imaging, which introduces oscillatory motion to magnetic bead-conjugated rare cells of interest through a periodic magnetic force and uses lensless time-resolved holographic speckle imaging to rapidly detect the target cells in three-dimensions (3D). Detection specificity is further enhanced through a deep learning-based classifier that is based on a densely connected pseudo-3D convolutional neural network (P3D CNN), which automatically detects rare cells of interest based on their spatio-temporal features under a controlled magnetic force. This compact, cost-effective and high-throughput computational cytometer can be used for rare cell detection and quantification in bodily fluids for a variety of biomedical applications.

Abstract: Described herein are techniques for denoising images of samples produced using polarization microscopy. Polarization images captured by polarization microscopy contain not only signals produced from polarization, but also signals produced from scattering by artifacts (e.g., crystals and/or hemosiderin). These off-target signals reduce the signal-to-noise ratio (SNR) of the birefringent substance of interest, and reduce the utility and accuracy of polarization microscopy for substance quantification. The techniques developed by the inventors and described herein reduce noise resulting from scattering, thus enabling much cleaner, noise-reduced images. The images so produced can be either directly visualized by a medical practitioner or used for downstream machine-learning models. Noise reduction involves i) dividing an image in segments (e.g., pixels or groups of pixels), ii) performing spectral analysis of each segment, and iii) separating each segment on the basis of its spectral profiles.

Abstract: In some aspects, a method, a system, or a non-transitory computer-readable storage medium are described for using a machine learning (ML) model to obtain annotations of a pathology slide image obtained in a first imaging modality, where the ML model is trained based in part on images obtained from a second imaging modality different from the first imaging modality. The first imaging modality is a conventional scanner for whole-slide images (WSI). The second imaging modality may include one or more of multispectral imaging (MSI), polarization imaging, quantitative phase imaging, or a combination thereof. The trained ML model can generate annotations that include more details with higher accuracy in comparison to annotating based on the WSI images alone.

Abstract: A jelly-roll type electrode assembly includes an electrode plate and a separation layer disposed on at least one surface of the electrode plate. A bonding force of the separation layer to a surface of the electrode plate in a first region of the jelly-roll type electrode assembly is greater than a bonding force of the separation layer to the surface of the electrode plate in a second region of the jelly-roll type electrode assembly.

Abstract: A classification model can be trained by using an augmented scene. The augmented scene may be generated by placing augmentation objects into a simulated scene that is a virtual representation of a real-world scene. The augmentation objects are virtual objects representing a category for which a reference classification model has a poor performance. The reference classification model may be a simulated model trained by using a simulated scene or a real-world model trained by using a real-world scene. A training set, which includes simulated sensor data of the augmentation objects and labels of the augmentation objects, can be used to train the augmented model. The augmented model can be used by an AV to classify objects in the surrounding environment of the AV. The augmented model can have a better accuracy in classifying objects in the category than the reference classification model.
