Abstract: A device for passive collection of atmospheric carbon dioxide is disclosed. The device includes a release chamber having an opening and a sorbent regeneration system. The device also includes a capture structure coupled to the release chamber, having at least one collapsible support and a plurality of tiles spaced along the collapsible support. Each tile has a sorbent material. The capture structure is movable between a collection configuration and a release configuration. The collection configuration includes the capture structure extending upward from the release chamber to expose the capture structure to an airflow and allow the sorbent material to capture atmospheric carbon dioxide. The release configuration includes the collapsible support being collapsed and the plurality of tiles being sufficiently enclosed inside the release chamber that the sorbent regeneration system may operate on the plurality of tiles to release captured carbon dioxide from the sorbent material and form an enriched gas.

Abstract: Described herein are systems, methods, and apparatuses for actively and continually fine-tuning convolutional neural networks to reduce annotation requirements, in which the trained networks are then utilized in the context of medical imaging. The success of convolutional neural networks (CNNs) in computer vision is largely attributable to the availability of massive annotated datasets, such as ImageNet and Places. However, it is tedious, laborious, and time consuming to create large annotated datasets, and demands costly, specialty-oriented skills. A novel method to naturally integrate active learning and transfer learning (fine-tuning) into a single framework is presented to dramatically reduce annotation cost, starting with a pre-trained CNN to seek “worthy” samples for annotation and gradually enhances the (fine-tuned) CNN via continual fine-tuning. The described method was evaluated using three distinct medical imaging applications, demonstrating that it can reduce annotation efforts by at least half compared with random selection.

Abstract: Provided herein are methods of differentiating cell types in a cell population. The methods include removing at least some non-Chimeric Antigen Receptor (CAR)-T cells from a fluidic sample obtained from a subject without centrifuging the fluidic sample to produce a purified fluidic sample. The fluidic sample comprises CAR-T cells and the non-CAR-T cells. The methods also include capturing cells in the purified fluidic sample on a surface that comprises binding moieties that bind at least to the CAR-T cells to produce a captured cell population. In addition, the methods also include distinguishing the CAR-T cells from the non-CAR-T cells in the captured cell population using a trained machine learning model to produce a captured CAR-T cell population data set. Additional methods as well as related devices and systems are also provided.

Abstract: Systems & methods for sorting single-walled carbon nanotubes (SWNTs) using an iDEP-based sorting device. The device includes an inlet channel with a constriction and the inlet channel splits into multiple different channels after the constriction—the multiple channels includes a center channel and at least one side channel. A sample is introduced into the iDEP sorting device containing a plurality of SWNTs of different lengths suspended in a fluid. An electrical field is applied to the sample between a first electrode in the center channel and a second electrodes at a proximal end of the inlet channel. The applied electrical field causes longer SWNTs to move towards the side channels while the shorter SWNTs move towards the center channel. Accordingly, a first plurality of shorter SWNTs is then collected from the center channel and a second plurality of longer SWNTs is collected from the at least one side channel.

Abstract: A stepwise incremental pre-training for integrating discriminative, restorative, and adversarial learning in an AI model. Exemplary systems include means for receiving a training dataset for training a unified AI model. The unified AI model applies each of discriminative, restorative, and adversarial learning operations through three transferable components: a discriminative encoder, a restorative decoder, and an adversarial encoder. Stepwise incremental pre-training operations train the unified AI model, including pre-training the discriminative encoder via discriminative learning and attaching the trained discriminative encoder with the restorative decoder to form a skip-connected encoder-decoder, pre-training the skip-connected encoder-decoder via joint discriminative and restorative learning, and associating the pre-trained skip-connected encoder-decoder with the adversarial encoder. Training of the AI model is finalized by performing full discriminative, restorative, and adversarial learning on the training dataset using the unified AI model.

Abstract: A fast-tracking phase-locked-loop (PLL) with an analog mixer for phase detection and correction is provided. A frequency lock loop architecture as described herein is used for a PLL that can lock the phase of a local oscillator to an input reference signal of arbitrarily high frequency, even if the local oscillator and the input reference signal frequencies are originally very far apart. To accommodate arbitrarily high frequency input reference signals, embodiments use an analog mixer for the phase detector, rather than a phase-frequency detector (PFD). The analog mixer can be designed to operate on input signals with frequencies of 10's of GHz, whereas the PFD is limited to input frequencies of less than 1 GHz. Embodiments use a new architecture utilizing the concept of Hartley Image Rejection receiver architecture in a frequency lock loop, which enables the PLL to adjust the local oscillator frequency to be brought within the frequency locking range of the analog mixer.
