Abstract: In many embodiments of the invention, a space-based data center includes orbital server modules configured to be deployed in space, each module including a communication subsystem for module-to-module communications to form a data center, tiles arranged in a planar array, where each tile has a layered structure including solar cells forming a layer across a first surface, thermal radiator panels forming a layer across a second surface, electronic components distributed laterally in a layer between the layer of solar cells and the layer of thermal radiator panels, where each electronic component receives power locally from solar cells and rejects heat to the thermal radiator panel beneath it, where a first subset of tiles are compute tiles in which the electronic components include one or more computing processors and memory, and where a second subset of tiles are support tiles in which the electronics components include network switches and energy storage.

Abstract: The disclosure relates to techniques for transferring a pulse pressure waveform signal of a peripheral vascular site to a central vascular site. In some implementations, a method includes: obtaining a time-domain representation of a first pulse pressure waveform signal of a brachial artery of a subject; converting the time-domain representation of the first pulse pressure waveform signal to a frequency-domain representation of the first pulse pressure waveform signal; selecting a first plurality of frequency components of the frequency-domain representation of the first pulse pressure waveform signal; predicting, using a non-linear mapping, based on the first plurality of frequency components, a second plurality of frequency components of a frequency-domain representation of a second pulse pressure waveform signal of an ascending aorta or left ventricle of the subject; and converting the frequency-domain representation of the second pulse pressure waveform signal to a time-domain representation of the second pulse pressure waveform signal.

Abstract: An electrically small electroquasistatic antenna having a structure that reduces radiated magnetic fields and maintains suitable radiated electrical fields. The electroquasistatic antenna is a dipole antenna that is electrically short, which presents as a capacitor for use as an electroquasistatic antenna, with one or multiple counterposed inductive elements to resonate the antenna and provide high efficiency while simultaneously canceling the external magnetic fields. The electroquasistatic antenna may be configured for operation as an electroquasistatic exciter or electroquasistatic detector.

Abstract: Systems and methods for a wearable system that monitors various biomarkers with a 3D-printed wearable electronic skin. Specifically, the wearable system is a 3D-printed epidermal wearable microfluidic electronic skin that may be composed of a combination of multidimensional nanomaterials, polymers, and hydrogels. The epidermal wearable microfluidic electronic skin may be integrated with sensors, electrodes, microfluidics, and a processor to collect and analyze molecular biomarkers of biofluid samples on the user's skin, while simultaneously analyzing the user's physiological biomarkers to conduct a health status assessment or gather health monitoring/surveillance metric.

Abstract: Provided herein are methods and systems and related devices and compositions for electrochemical control of viability of redox active bacteria. The electrochemical control is performed by applying to a working electrode contacting a medium known or suspected to comprise the redox active bacteria, a reducing potential which is lower of the midpoint potential of a redox active compound produced by the redox active bacteria.

Abstract: The present disclosure relates to a method of making core-shell and yolk-shell nanoparticles, and to electrodes comprising the same. The core-shell and yolk-shell nanoparticles and electrodes comprising them are suitable for use in electrochemical cells, such as fluoride shuttle batteries. The shell may protect the metal core from oxidation, including in an electrochemical cell. In some embodiments, an electrochemically active structure includes a dimensionally changeable active material forming a particle that expands or contracts upon reaction with or release of fluoride ions. One or more particles are at least partially surrounded with a fluoride-conducting encapsulant and optionally one or more voids are formed between the active material and the encapsulant using sacrificial layers or selective etching. The fluoride-conducting encapsulant may comprise one or more metals. When the electrochemically active structures are used in secondary batteries, the presence of voids can accommodate dimensional changes of the active material.
