Abstract

Herein we demonstrate a method of high energy delamination called high pressure homogenization (HPH) that combines high shear, cavitation forces, and impact forces to delaminate MXene without any post-process refinement steps or chemical intercalants. HPH-delaminated MXene can be made at scale with high throughput and yield with virtually no waste. We demonstrate the viability of this process by fabricating free-standing films with the material for use as electrodes for energy storage, and as an effective antimicrobial coating with a two-log reduction in pathogenic microbes.

Abstract

Reconfigurable intelligent surfaces (RISs) are an emerging transmission technology to aid wireless communication. However, the potential of using RIS to mitigate directed energy weapons (DEW) is not widely recognized. Described herein are RIS (based on spiral antenna elements) to aid the mitigation of high-energy radio-frequency (RF) sources applied to a DEW. For example, integrating a broadband circularly-polarized antenna system with RIS technology can successfully mitigate DEW attacks across a wide range of frequencies regardless of how radio waves are polarized. A spiral antenna is simulated that operates between 1.3 GHz and 7 GHz with a 3-dB axial ratio bandwidth (ARBW) covering 2 GHz-7 GHz. Full-wave simulation results show the potential promising application of RIS for the mitigation of DEW attacks.

Abstract

Solid-state circuit breakers (SSCBs) have been witnessing an impressive progress with the aid of wide bandgap (WBG) devices such as silicon carbide (SiC) MOSFETs. Along with obtaining high efficiency as the result of low on-state resistance, response times have been gaining remarkable achievements in microseconds range. Not only that, the reported successes in control and gate drivers design and incorporating fault detection/location techniques in SSCBs are promising. A MOV-resistive capacitive switch (MOV-RCS) snubber for solid state circuit breakers addresses the following: 1) the MOV degradation issue in DCCBs is solved, 2) the maximum allowable DC bus voltage on DCCBs is extended. The solid state circuit breaker and an active clamping snubber includes a first circuit including a fault current bypass based solid state breaker for low voltage direct current systems.

Abstract

In absence of electrical approaches for realization of highly stable RF oscillator, opto-electronic oscillators (OEO) techniques are provided, where self-forced oscillation techniques using long optical delays demonstrate significant short-term and long-term frequency stability. Fully integrated opto-electronic oscillator chip (IOEC) may be the most efficient realization of an RF frequency synthesizer in terms of operation frequency (covering microwave and millimeter wave), size (<10 cm3), ruggedness to environmental effects of temperature (−40 to 80C), vibration (up to 40g), low timing jitter (<5fs for 40 GHz carrier), and wall-plug efficiency (output power >10 dBm from under 1 W power). A free-running III-V (primarily InP) based multi-mode laser (MML) diodes is designed with large mode number (e.g., over 60 modes) and intermodal oscillation frequency compatible with desired RF carrier signal (e.g., 1-40 GHz).

Abstract

Ionic liquid N-methyl-N-propyl-pyrrolidinium bis(fluorosulfonyl)imide (Pyr13FSI) was introduced into a hybrid network to obtain a series of gel polymer electrolytes (GPEs). Mechanical and electrochemical properties of the GPEs were tuned through controlling the network structure and ionic liquid contents, and ionic conductivity higher than 1 mS cm−1 at room temperature was achieved. The newly developed GPEs are flame-retardant and show excellent thermal and electrochemical stability as well as ultra-stability with lithium metal anode. Symmetrical lithium cells with the GPEs exhibit a stable cycling over 6800 h at a current density of 0.1 mA cm−2 and stable lithium stripping-plating at 1 mA cm−2, the highest current density reported for ionic liquid-based GPEs. Moreover, Li/LiFePO4 batteries with the obtained GPEs exhibit desirable cycling stability and rate performance over a wide temperature range from 0° C. to 90° C.

Abstract

A system develops classifiers that can aid medical professionals by diagnosing whether or not a patient has a medical condition like pneumothorax. The system breaks the task into multiple steps, using Y0L0v4 to extract relevant regions of the video and a 3D sparse coding model to represent video features. Given the difficulty in acquiring positive training videos, the inventors trained a small-data classifier with a maximum of 15 positive and 32 negative examples. To counteract this limitation, the inventors leveraged subject matter expert (SME) knowledge to limit the hypothesis space, thus reducing the cost of data collection. The inventors present results using two lung ultrasound datasets and demonstrate that the inventors' model is capable of achieving performance on par with SMEs in pneumothorax identification.

Abstract

A system defends against puppeteering attacks in low bandwidth talking head videoconferencing systems. The defensive system is a software that can be embedded within existing platforms or an operating system and it exploits the fact that the facial expression and pose information sent to the receiver inherently contain biometric information about the driving speaker. The system leverages this information to obtain measurements of the biometric distance between the driving and reconstructed speaker. If the biometric distance becomes large, this indicates that the driving speaker is a different person than the reconstructed speaker. The system then flags the video transmission as a puppeteering attack.

Abstract

Backpropagation enabled neural network optimization, but is still expensive at scale. An efficient alternative for neural networks must reduce scaling costs and provide high-efficiency optimizations. The presented solution for feed-forward layers is extended compositionally, for transformers containing feed-forward and self-attention layers. These train complex models modularized by self-attentive feed-forward units (SAFFUs), defining efficient architectures that generalize over much less data. Results demonstrate outperformance of backpropagation (alone), compared to application of backpropagation after explicit solutions, which uncover better optima from less data. Ablations train a roadmap of 245 transformers to determine specifications for the SAFFU- transformer, showing several architectural variants appear quite performant. The most performant models appear to not be the most parameterized. Summarizing, well-generalized SAFFU models are efficiently reachable, their architectural explorability via explicit solutions is cheaper and more robust than by backpropagation, and their explicit solutions could be useful for low-resource hardware, where Al might be embodied.

Abstract

An integrated portable extremely fast charger (XFC) may be installed for heavy-duty off-road vehicles, such as tractors and combine harvesters. The XFC shortens the charging period of plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) by providing >500 kW in a single charger. The proposed XFC integrates a solar farm and local energy storage system (ESS) such that the local grid only needs to provide the power gap between the vehicle battery and the local ESS during charging events, yielding a low-cost XFC installation and higher renewable energy penetration. Two design approaches for the XFC, conductive and wireless, are based on multiphase interleaved dc-dc converter circuit, permitting flexible access to electricity. Smart fault protection mechanism is also proposed to achieve high safety during charging events. The hexagonal prism charger may be integrated into the power electronic devices with a transformer, yielding a high compactness and power density.

Abstract

Vascularization in nature creates a constituent system that enhances thermal exchange between components and autonomously responds to different environmental stimuli, such as moisture and temperature, to create equilibrium for organisms. Infrastructure designed with traditional design methods often encounters degradation over their lifespan without featuring autonomous responses to chemical/mechanical deterioration imposed by harsh environments. Vascular architectures can be engineered for further application in construction materials to provide necessary mass/heat transport for thermo-regulation in infrastructure. This concept is investigated using a phase change material (PCM) liquid injected into various architected vascular networks. The invention provides vascular networks using sacrificial components at multi-length scales and integrates PCM thermal self-responsive functionality in cementitious composites.

Abstract

A method of detecting the length of an individual telomere is provided. In one embodiment, the method includes contacting genomic DNA with a guide RNA having a portion complementary to a telomere repeat sequence in the genomic DNA and with Cas9 nickase to produce a single-strand break in the genomic DNA at the telomere repeat sequence. The nicked DNA is contacted with a polymerase and fluorescently labeled nucleotide, wherein the fluorescently labeled nucleotide is incorporated into the nicked DNA at the telomere repeat sequence. The genomic DNA is contacted with a second nicking endonuclease which is specific for a sequence motif in the genomic DNA thereby producing a second nick in the genomic DNA at the motif sequence. The nicked DNA is contacted with a polymerase and second fluorescently labeled nucleotide of different color, wherein the second fluorescently labeled nucleotide is incorporated into the nicked DNA at the motif sequence location. The length of the telomere is detected by measuring the fluorescence of first fluorescently labeled nucleotide at the telomere repeat location, wherein the fluorescently labeled motif sequences are used as a barcode to identify the chromosome.

Abstract

A field-programmable analog array (FPAA) fabric includes a 6×6 matrix of configurable analog blocks (CABs). The implementation of programmable CABs eliminates the use of fixed analog subcircuits. A unique routing strategy is developed within the CAB units that supports both differential and single-ended mode circuit configurations. The bandwidth limitation due to the routing switches of each individual CAB unit is compensated for through the use of a switch-less routing network between CABs. Algorithms and methodologies facilitate rapid implementation of analog circuits on the FPAA. The proposed FPAA fabric provides high operating speeds as compared to existing FPAA topologies, while providing greater configuration in the CAB units as compared to switch-less FPAA. The FPAA core includes 498 programming switches and 14 global switchless interconnects, while occupying an area of 0.1 mm2 in a 65 nm CMOS process.

Abstract

A superconducting solid-state circuit breaker (S3CB) may be used in direct current (DC) power system applications. The proposed protective S3CB has two main protective functions. First, it slows down a rising rate of fault currents by using superconductors. A new quench resistor accelerator is proposed to fasten superconductors' response time to solve the low inertia of DC power systems. In addition, a quench protection branch is used to protect the superconductors from localized hotspots during current limiting processes. Second, the proposed S3CB includes an ultrafast solid-state circuit breaker (SSCB) which isolates faulty sections or disconnect loads within microseconds.

Abstract

Manufacturing lightweight aggregate (LWA) by a sintering technique requires a delicate balance among three conditions: forming sufficient amount of molten liquid phase during sintering; reaching an appropriate viscosity for solid-liquid suspension; and emitting sufficient amount of gas that can be entrapped by the liquid phase to form pores. LWAs were made from low-calcium and high-calcium Waste Coal Combustion Ash (W-CCA) including fly ash and bottom ash. A mass fraction of at least 40% liquid phase for fly ash and 50% for bottom ash is required for a successful entrapment of emitted gaseous phases during sintering. Larger pores were observed in the microstructure of LWA samples made using high-calcium W-CCA in comparison to low-calcium W-CCA. This result was mainly attributed to the high-calcium samples forming liquid phases with lower viscosity values and emitting higher amounts of gaseous phase during sintering than did the low-calcium samples. The gaseous phase was generated by hematite reduction and anhydrite decomposition.

Abstract

A simulation-based optimization framework determines the sizing of components of an analog circuit to meet target design specifications while also satisfying the robustness specifications set by the designer. The robustness is guaranteed by setting a limit on the standard deviations of the variations in the performance parameters of a circuit across all process and temperature corners of interest Classifier chains are used that, in addition to modeling the relationship between inputs and outputs, learn the relationships among output labels. Additional design knowledge is inferred from the optimal ordering of the classifier chain.
