A signal transmitted by a trusted transmitter is sampled, and a machine-learning algorithm is trained using these samples to learn to distinguish the signal characteristics of the trusted transmitter from the signal characteristics of other transmitters. The machine-learning parameters learned to distinguish the trusted transmitter's signals can then be exported allowing other devices to authenticate signals from the trusted transmitter. Since the signal characteristics of the trusted transmitter is based on manufacturing variations, the transmitters of unauthorized users should be unable to replicate the signal characteristics of the trusted transmitter. Thus, the transmitters of unauthorized users should not be usable to spoof a device that uses the exported parameters to authenticate messages from the trusted transmitter.

An augmented reality (AR) chemistry training system is disclosed, featuring a video see-through AR (VST-AR) device that captures a real-world scene and overlays interactive virtual content. A physical laboratory vessel analog (corporal entity) is equipped with capacitive tactile sensors on its exterior to detect user touch and grasp. A unique identification marker on the vessel allows the system's at least one processor to recognize the vessel type and retrieve corresponding parameters (such as virtual liquid properties) from a data store. In real-time, the processor generates visual augmentations inside the vessel, representing virtual chemicals that respond to the user's touch and motions. This tactile-responsive AR system safely simulates hands-on chemistry experiences—such as mixing liquids—by providing realistic visual reactions coupled with touch-based feedback, thereby enhancing user immersion and skill development.

An augmented reality chemistry system is presented that combines visual and thermal feedback to create immersive laboratory simulations. A video see-through AR headset or device captures the user's real environment and overlays virtual chemical reactions inside a physical analog vessel. The physical vessel analog is instrumented with a thermal diode embedded in its structure, capable of safely heating or cooling its surface to simulate exothermic or endothermic reactions. A unique marker on the vessel is tracked by the AR device, enabling a processor to anchor virtual liquid visuals to the vessel and retrieve predetermined reaction parameters from a database. As virtual reactions occur (e.g. mixing chemicals), the system dynamically adjusts the vessel's temperature via the thermal diode in sync with the visual augmentation, so the user can feel temperature changes corresponding to the reaction. This AR apparatus enriches remote chemistry training by providing realistic heat feedback and interactive visualizations without real hazardous materials.

A class of nanowires that possess enzyme-like catalytic activities, which are termed as “enzyme mimics”. The morphologies of such enzyme mimics are nanoscale wires (i.e., nanowires) of various lengths, diameters, and degrees of branching and bending. The composition of such enzyme mimics may contain various elements, but at least one is a platinum-group metal [including platinum (Pt), iridium (Ir), rhodium (Rh), palladium (Pd), and/or ruthenium (Ru)]. The nanowires as enzyme mimics can efficiently catalyze multiple chemical reactions that are typically catalyzed by natural enzymes (such as peroxidase, catalase, oxidase, and superoxide dismutase). For example, the nanowires can act as peroxidase mimics and catalyze the oxidation of chromogenic substrates by oxidizing agents (e.g., hydrogen peroxide), yielding colored products. In addition, disclosed here include the applications of such enzyme mimics in biosensing systems, wherein the enzyme mimics arc conjugated to bioreceptors (e.g., antibodies) and are used as labels or reporters.

Described herein relates to a method that may be used for synthesizing a bifunctional electrocatalyst for electrochemical water splitting. The method may involve anodically converting an electrodeposited iron-nickel alloy film into an iron-nickel-oxygen nanofilm, followed by sequential phosphorization and/or selenylation treatments via chemical vapor deposition to form a quaternary iron-nickel phosphoselenide nanoporous film. This self-supported catalyst can facilitate both hydrogen evolution and oxygen evolution reactions, improving electrolysis efficiency. The inclusion of selenium may enhance electrical conductivity and stabilize catalytic performance, while the nanoporous structure can optimize mass transport. The film may be used as both anode and cathode in a two-electrode electrolyzer, enabling hydrogen production from pure water or seawater. Notably, the catalyst can demonstrate high turnover frequency and low overpotential, potentially surpassing conventional noble-metal-based catalysts. The system's stability under prolonged operation may underscore its potential for scalable hydrogen generation, reducing reliance on fossil fuels and advancing renewable energy applications.

The invention provides a method for adapting a text-to-image (T2I) diffusion model for video editing by using spectral decomposition to achieve controlled spectral shifts in the model's weights. This adaptation involves maintaining constant singular vectors while selectively adjusting singular values in response to a text prompt. A spectral shift regularizer constrains adjustments, particularly limiting changes to larger singular values to ensure minimal deviation from the original model's structure. This approach allows efficient, prompt-driven video editing by modifying specific elements according to the prompt while preserving the original video context. By focusing on selective spectral adjustments, the method reduces adaptation time and computational demands, making it suitable for real-time and resource-sensitive applications, such as dynamic video editing for streaming services.

Hybridization probes have been used in the detection of specific nucleic acids for the last 50 years. Despite the extensive efforts and the great significance, the challenges of the commonly used probes include (1) low selectivity in detecting single nucleotide variations (SNV) at low (e.g., room or 37° C.) temperatures; (2) low affinity in binding folded nucleic acids, and (3) the cost of fluorescent probes. To address all three issues, a multicomponent hybridization probe, called OWL2 sensor, is introduced. OWL2 sensor uses two analyte binding arms to tightly bind and unwind folded nucleic acid analytes, and two sequence-specific strands that bind both the analyte and a universal molecular beacon (UMB) probe to form fluorescent ‘OWL’ structure. OWL2 sensor can differentiate single base variations in folded analytes in a temperature range of 5-38° C. The design is cost-efficient since the same optimized fluorescently labeled UMB probe can be used for the detection of any analyte sequence.

Abrégé

Efficient lung cancer treatment is challenging due to the lack of therapeutic targets. The succinate dehydrogenase (SDH) enzyme plays a critical metabolic role as an intermediate between the citric acid cycle and the electron transport chain associated with the cancer disease state. Although several existing compounds have been applied to target metabolic diseases in vitro, modulating SDH for lung cancer treatment has been elusive. By integrating the AtomNet® technology for compound identification with mitochondria- and cell-based enzyme activity assays, this disclosure demonstrates identification of four new small molecules that bind directly to SDH subunits in lung cancer cells. Mechanistically, treatment with these small molecules increased reactive oxygen species and DNA damage in lung cancer cell lines. Functionally, these small molecules reduced short-term and long-term malignant growth of lung cancer cell lines in vitro. This study provides a new therapeutic approach for targeting lung and other types of cancers through modulation of SDH.

Disclosed is a method to amplified nucleic acids by polymerase chain reaction (PCR) without isolation or purification from the biological samples. All the reactions associated with reverse transcriptase qPCR or real-time qPCR are completed on a filter paper chamber using a handheld Real-time PCR device. The process requires a very small amount of sample since there is no loss of materials associated with isolation and purification steps. The amplification process is faster than a normal tube-based PCR reaction because the thin chamber makes heating and cooling process fast. This technique is applicable in the rapid detection of pathogenic viruses from body fluids, such as COVID-19 detection in saliva. The technology is valuable for quantitative detection of nucleic acids that are established markers of diseases. Novel use of a piece of filter paper to perform sample collection, storage, and conduct direct PCR amplification without any extraction of the sample will allow us to test infections and the diseases anywhere by anybody without the requirement of technical knowledge or skills.

Numerous fields of basic research, medicine, and technology require an understanding of the biological composition and diversity in water samples. A common approach to acquiring such information is to collect samples ‘in the field’ and to subsequently extract nucleic acids in a laboratory for sequence analyses. A challenge to this pipeline is the preservation of the abundance and quality of the nucleic acids present in and around the organisms because, once a sample is harvested, it is no longer connected to the environment that established it. Many organisms, particularly microbes, rapidly adapt to such environmental changes and the relative abundance and quality of nucleic acids within them can change in a manner of minutes. A common methodology intended to address this problem is to filter the water to collect microorganisms on site and then to store the filters in a frozen state until they are processed. This technique creates several problems: the filter systems are expensive, require a vacuum, and are cumbersome to operate; the microbes change their metabolisms as they are filtered; freezing the samples requires substantial infrastructure at the collection site and during transport; and freezing and thawing many organisms causes their cells to break open, which releases their nucleic acids. The disclosed invention circumvents these problems by allowing microorganisms and their nucleic acids to be rapidly preserved on site using simple collection vessels, without the need for refrigeration or freezing. The methodology allows for the subsequent recovery and processing of nucleic acids for downstream molecular analyses. Although the current embodiment was developed for sea water collection, it can be also be applied to other aqueous samples

Abrégé

CNN-based methods for cross-view image geo-localization rely on polar transform and fail to model global correlation. A pure transformer-based approach (TransGeo) is described to address these limitations from a different perspective. TransGeo takes full advantage of the strengths of the transformer related to global information modeling and explicit position information encoding. The claimed invention further leverages transformer input's flexibility and discloses an attention-guided non-uniform cropping method so that uninformative image patches are removed with a negligible drop in performance to reduce computation cost. The saved computation can be reallocated to increase resolution only for informative patches, resulting in performance improvement with no additional computation cost. This “attend and zoom-in” strategy is highly similar to human behavior when observing images. Remarkably, TransGeo achieves state-of-the-art results on both urban and rural datasets, with significantly less computation cost than CNN-based methods. It does not rely on polar transform and provides faster methods.
