Abstract: Compositions and methods are described for inducing an immune response against an immunogen in humans. The induced immune response is obtained by administering a heterologous prime-boost combination of an in vitro transcribed (IVT) self-replicating RNA (repRNA) and an adenovirus vector. The compositions and methods can be used to provide a protective immunity against a disease, such as a viral infection or a cancer, in humans.

Abstract: A system for non-invasive hematological measurements includes a platform to receive a body portion of a user and an imaging device to acquire a set of images of a capillary bed in the body portion. For each image, a controller detects one or more capillaries in the body portion of the finger to identify a first set of capillaries by estimating one or more attributes of each capillary (e.g., structural attributes, flow attributes, imaging attributes, or combinations thereof), wherein at least one attribute of each capillary meets a predetermined criterion. The controller also identifies a second set of capillaries from the first set of capillaries such that each capillary of the second set of capillaries is visible in a predetermined number of images of the set of images.

Abstract: Meta-lens based ocular imaging, near-eye display, and eye-tracking systems are described. The systems can include a single focusing optic and an integrated circuit that provides illumination light and includes an imaging array. The focusing optic includes meta-atoms formed on a substrate. The systems may have no moving parts and achieve imaging or image-projection fields-of-view approaching or exceeding 180 degrees. Because of their low part count, the systems can be robust and have a very small form factor.

Abstract: Provided herein are genetic circuits and encoded RNA transcripts that produce an output molecule in response to an RNA cleavage event that removes a degradation signal. In some embodiments, the genetic circuits described herein may be used for detecting RNA cleaver activities (e.g., in a cell). Methods of using the genetic circuits described herein in diagnostic or therapeutic applications are also provided.
Abstract: An electrochemical device includes a transition metal oxide cathode, such as LiNi0.8Co0.1Mn0.1O2, and an electrolyte. The electrolyte includes N, N-dimethyltrifluoromethane-sulfonamide (DMTMSA) and lithium bis(fluorosulfonyl)imide (LiFSI). The DMTMSA and LiFSI may be either the primary component of the electrolyte or an additive in the electrolyte. The electrochemical device may also include a graphite anode or a lithium metal anode. With a lithium metal anode, the electrochemical device has an initial specific capacity of at least 231 mAh g?1. Over at least 100 cycles (upper cut-off voltage of 4.7±0.05 V vs. Li/Li+), the electrochemical device maintains an average specific capacity of at least 88% of the initial specific capacity and an average Coulombic efficiency of at least about 99.65%.

Abstract: The present disclosure relates to methods and compositions for enhanced assessment of exogenous polynucleotide and/or polypeptide-mediated transcriptional perturbations at high throughput and single cell/droplet levels of resolution. In embodiments, nucleic acid fusions of exogenous polynucleotide(s) and associated target transcript(s) are produced within individually sequestered or discretely identifiable cells/lysates and analyzed for exogenous polynucleotide mediated perturbations across a vast population of droplets/cells within individual reactions. Kits for performance of the methods are also provided.

Abstract: Methods for controlled segregation of blocks of information encoded in the sequence of a biopolymer, such as nucleic acids and polypeptides, with rapid retrieval based on multiply addressing nanostructured data have been developed. In some embodiments, sequence controlled polymer memory objects include data-encoded biopolymers of any length or form encapsulated by natural or synthetic polymers and including one or more address tags. The sequence address labels are used to associate or select memory objects for sequencing read-out, enabling organization and access of distinct memory objects or subsets of memory objects using Boolean logic. In some embodiments, a memory object is a single-stranded nucleic acid scaffold strand encoding bit stream information that is folded into a nucleic acid nanostructure of arbitrary geometry, including one or more sequence address labels. Methods for controlled degradation of biopolymer-encoded blocks of information in the memory objects are also developed.

Abstract: Thin films of lithium-containing materials and methods for fabricating them are generally described. In some embodiments, the formation of a first vapor is induced from a first target and the formation of a second vapor is induced from a second target, resulting in the formation of a thin film. In some embodiments, at least a portion of the formation of the first vapor and the formation of the second vapor occurs under vacuum conditions. In some embodiments, the thin film has a relatively high ionic conductivity, mixed ionic/electronic conductivity, or other properties beneficial for applications such as active electrode materials or solid-state electrolytes.

Abstract: A decoder includes a feature extraction circuit for calculating one or more feature vectors. An acoustic model circuit is coupled to receive one or more feature vectors from and assign one or more likelihood values to the one or more feature vectors. A memory architecture that utilizes on-chip state lattices and an off-chip memory for storing states of transition of the decoder is used to reduce reading and writing to the off-chip memory. The on-chip state lattice is populated with at least one of the states of transition stored in the off-chip memory. An on-chip word is generated from a snapshot from the on-chip state lattice. The on-chip state lattice and the on-chip word lattice act as an on-chip cache to reduce reading and writing to the off-chip memory.
