Abstract: The subject invention pertains to methods and systems for classifying leukocytes using artificial intelligence called AIRFIHA (artificial-intelligence enabled reagent-free imaging hematology analyzer) that can accurately classify subpopulations of leukocytes in a label-free manner. AIRFIHA can not only subtype lymphocytes into B and T cell but is capable of sorting different types of T cells subtypes. AIRFIHA is realized through training a two-step neural network using label-free images of separated leukocytes acquired from a custom-built quantitative phase microscope. Owing to its easy operation, low cost, and strong discerning capability of complex leukocyte subpopulations, AIRFIHA is clinically translatable and can also be deployed in resource-limited settings.

Abstract: Predictions of current and/or future neurocognitive decline (NCD) can be based on functional neuroimaging data (e.g., fMRI data) and a machine-learning classifier model. Functional neuroimaging data is obtained while the subject performs a naturalistic language-processing task, such as watching a movie clip, and processed to extract a quantitative feature set. A classifier model is trained using machine learning techniques to predict a subject's NCD status based on the quantitative feature set.

Abstract: Size-band analysis is used to determine whether a chromosomal region exhibits a copy number aberration or an epigenetic alteration. Multiple size ranges may be analyzed instead of focusing on specific sizes. By using multiple size ranges instead of specific sizes, methods may analyze more sequence reads and may be able to determine whether a chromosomal region exhibits a copy number aberration even when clinically-relevant DNA may be a low fraction of the biological sample. Using multiple ranges may allow for the use of all sequence reads from a genomic region, rather than a selected subset of reads in the genomic region. The accuracy of analysis may be increased with higher sensitivity at similar or higher specificity. Analysis may include fewer sequencing reads to achieve the same accuracy, resulting in a more efficient process.

Abstract: This invention discloses a pneumatic and cable-driven hybrid artificial muscle, comprising pneumatic actuator, pneumatic pressure regulating assembly, and cable drive assembly. The pneumatic pressure regulating assembly is connected to the pneumatic actuator to regulate air pressure in the pneumatic actuator for controlling the pneumatic actuator to extend or contract. The cable actuation assembly comprises a cable fixedly connected to the pneumatic actuator for controlling the pneumatic actuator to contract. In this invention, the artificial muscle employs a dual pneumatic and cable actuation mechanism. By leveraging the inherent stiffness of the pneumatic actuator, it can provide substantial actuation force for joint movement. Simultaneously, the cable actuation assembly can provide significant pulling force, effectively ensuring safety in human-machine interaction and offering sufficient bidirectional aiding force to individuals with disabilities who use the artificial muscle as an aiding actuation device.

Abstract: The invention develops a novel hole-transporting material (HTM), PTAA-P1 and PTAA-P2 via the backbone engineering strategy to modulate wettability and promote anchoring. The HTM properties can be effectively modified by varying the linkage sites of incorporated pyridine units.

The invention also develops the perovskite solar cell including the novel HTM with remarkable PCE efficiency and stability for small-area and large-area solar cells. The invention also develops the method for fabricating the perovskite solar cell.

Abstract: An automatic system which combines a three-branch sorter with three independently-controlled valves and corresponding collection platforms. The subgroups of droplets are alternatively sorted into three channels followed by being pumped out into PCR tubes on the platforms. Experimentally, this system can realize an accurate collection with a large working range for both pure positive samples and mixed samples with negative ones. This technology effectively dispenses a large number of droplets into small subgroups with quantitative number, which builds the basis for digital droplet microfluidics.

Abstract: Two-dimensional face presentation attacks are one of most notorious and pervasive face spoofing types, causing security issues to facial authentication systems. To tackle these issues, a cost-effective face anti-spoofing (FAS) system based on acoustic modality, named as Echo-FAS, is devised, which employs a crafted acoustic signal to probe the presented face. First, a large-scale, high-diversity, acoustic-based FAS database, named as Echo-Spoof, is built. Based upon Echo-Spoof, we design a two-branch framework combining global and local frequency features of the presented face to distinguish live vs. spoofing faces. Echo-FAS has the following merits: (1) it only needs one speaker and one microphone; (2) it can capture three-dimensional geometrical information of the presented face and achieve a remarkable FAS performance; and (3) it can be handily allied with RGB-based FAS models to mitigate the overfitting problem in the RGB modality and make the FAS model more accurate and robust.
