  • Publication number: 20250148260
    Abstract: Disclosed is a technique for improving the throughput of a neural network, using multiplexing and demultiplexing of information. Specifically, the multiplexing may include receiving a plurality of inputs, generating transformed inputs by performing, via a multiplexing layer, a transformation to each input of the plurality of inputs, and combining the transformed inputs into a single compact representation of the plurality of inputs. The demultiplexing may include receiving an output from a neural network, generating a plurality of values by converting, via a demultiplexing layer, the output back into independent representations, and producing predictions for each input based on the plurality of values. Further improvements may be seen when pretraining of the neural network and/or high-throughput transformers are incorporated.

  • Publication number: 20250146089
    Abstract: Disclosed is a method for quantitative detection of a small, aberrant viral nucleic acid. The method includes combining a detection mixture with a sample, and allowing a reaction with the test mixture to begin. The sample includes an RNA sample. The detection mixture includes a Cas13 enzyme, a reporter, a sequence-specific CRISPR RNA (crRNA), and a buffer. The method includes determining a quantitative value representative of the reporter in the test mixture, where the quantitative value is a measure of an amount of target RNA present in the RNA sample.

  • Publication number: 20250117552
    Abstract: A design methodology and tool called INFORM are provided that use a two-phase approach for sample-efficient constrained multi-objective optimization of real-world nonlinear systems. In the first optional phase, one may modify a genetic algorithm (GA) to make the design process sample-efficient, and may inject candidate solutions into the GA population using inverse design methods. The inverse design techniques may be based on (i) a neural network verifier, (ii) a neural network, and (iii) a Gaussian mixture model. The candidate solutions for the next generation are thus a mix of those generated using crossover/mutation and solutions generated using inverse design. At the end of the first phase, one obtains a set of nondominated solutions. In the second phase, one chooses one or more solution(s) from the non-dominated solutions or another reference solution to further improve the objective function values using inverse design methods.

  • Publication number: 20250115951
    Abstract: Disclosed are techniques for enhanced nucleic acid detection using blocked or partially blocked crRNAs or target RNAs, and a composition of matter (detection reactions consisting of occluded crRNAs or target RNAs). Here, the mechanism of Cas 13 protein activation in response to RNA structure perturbations was systematically probed using a massively multiplexed screen. It was found that there are two distinct sequence-independent modes by which secondary structure affects Cas13 activity: structure in the protospacer region competes with the crRNA and can be disrupted via a strand-displacement mechanism, while structure in the region 3? to the protospacer has an allosteric inhibitory effect. The kinetic nature of the strand displacement process was leveraged to improve Cas13-based RNA detection and enhance mismatch discrimination by up to 50-fold, enabling sequence-agnostic mutation identification at low (<1%) allele frequencies.

  • Patent number: 12236625
    Abstract: The present disclosure relates generally to image processing, and more particularly, toward techniques for structured illumination and reconstruction of three-dimensional (3D) images. Disclosed herein is a method to jointly learn structured illumination and reconstruction, parameterized by a diffractive optical element and a neural network in an end-to-end fashion. The disclosed approach has a differentiable image formation model for active stereo, relying on both wave and geometric optics, and a trinocular reconstruction network. The jointly optimized pattern, dubbed “Polka Lines,” together with the reconstruction network, makes accurate active-stereo depth estimates across imaging conditions. The disclosed method is validated in simulation and used with an experimental prototype, and several variants of the Polka Lines patterns specialized to the illumination conditions are demonstrated.

  • Patent number: 12232158
    Abstract: Use of high frequency waves, such a millimeter waves, in many circumstances is prevented due to their inability to diffract around common obstacles. Disclosed herein is a system and method for transforming an incident high frequency wave. The system includes meta-atom pairs that define a surface. The meta-atom pairs generate an electro-magnetic response by interacting with an incident wave. This electro-magnetic response can be modulated by applying voltage to the meta-atom pairs. The electro-magnetic response transforms the incident wave into an emitted wave based on its controlled properties. The system and method are able to, by changing the voltage applied, steer the emitted wave a full 360 degrees as wells as transmit it through the surface without significant power loss. Embodiments enable the transmission through or around many obstacles that would normally interfere with high frequency waves.
