Abstract: A round superconductor wire and method for fabricating same are disclosed. Embodiments are directed to a round superconductor wire including at least two superconductor tapes wound on a wire former. Each superconductor tape includes: bottom stabilizer and silver layers; substrate disposed above the bottom silver layer; buffer film stack disposed above the substrate; superconductor film disposed above the buffer film stack; top silver layer disposed above the superconductor film; and top stabilizer layer disposed above the top silver layer. At least one of the bottom stabilizer layer, bottom silver layer, substrate, buffer film stack, superconductor film, top silver layer, or top stabilizer layer is of a different width, thickness, or material composition in one of the superconductor tapes than in another of the superconductor tapes. These and other embodiments achieve a round superconductor wire having improved current density in high magnetic field applications when made in small diameters.

Abstract: The systems and methods described herein are for monitoring the tightness of bolts. The systems and methods may be used with a mechanism to apply a percussive tap and with a recording or monitoring device for detecting and recording the acoustic signals that are generated by the percussive tap. The acoustic signals generated by percussive taps applied to bolts in various looseness states are analyzed and a machine learning model is developed that allows for determining bolt looseness based on the acoustic signals.

Abstract: A soleus contraction measurement system includes a sensor configured to measure rotational movement when positioned on a user's foot with an X-axis oriented laterally across the user's foot, a Y-axis oriented parallel to the user's foot, a Z-axis orthogonal to the X-axis and the Y-axis, and a positive X-axis rotational movement corresponding to an increasing ankle angle, and a memory storing computer-executable instructions for controlling a processor to: measure an X-axis rotational movement, identify a positive X-axis rotational movement as a plantarflexion and a negative X-axis rotational movement as an ankle dorsiflexion, deem the plantarflexion a performed soleus contraction when the plantarflexion is immediately followed by the ankle dorsiflexion for two consecutive cycles of plantarflexion and ankle dorsiflexion, and cause performance information regarding the performed soleus contractions to be communicated.

Abstract: Durable antibacterial coatings are prepared by inter-diffusing zwitterionic polyurethane in acrylic polyurethane. Bacterial attachment is substantially eliminated from the surface of the coatings due to the hydrophilicity of the zwitterionic polyurethane. Long-term antibacterial properties were observed for both Gram-negative and Gram-positive bacteria even when the coatings were constantly challenged by mechanical abrasion.

Abstract: Nano-sized zeolites may be prepared using germanium oxide (GeO2) as a component of the overall synthesis composition. This is accomplished by the addition of GeO2 as an inexpensive reagent for the synthesis gel. Most of the Ge is retained in the synthesis mixture and the small amount incorporated in the zeolite solid (Si/Ge>100) does not have an appreciable impact on zeolite acidity or other physicochemical properties. The methods disclosed herein circumvent challenges to prepare nano-sized zeolites having dimensions less than 100 nm.

Abstract: A method and system for quench detection in high temperature superconductors, such as REBCO (rare-earth barium copper oxide), before thermal runaway. A REBCO superconducting tape is excited as a transmission line forming standing waves. A quench may then be detected in response to detecting a disturbance of the standing waves. In this manner, quench in high temperature superconductors, such as REBCO, is rapidly detected before thermal runaway.

Abstract: A method including capturing carbon dioxide (CO2) from air (e.g., atmosphere) in an absorber in which the air contacts a base (e.g., a hydroxide, such as potassium hydroxide KOH and/or sodium hydroxide (NaOH)) to produce a carbonate (e.g., potassium carbonate (K2CO3) and/or sodium carbonate (Na2CO3)); precipitating one or more (e.g., carbonate) salt from an aqueous solution comprising salt (a brine) to provide an aqueous solution comprising a chloride (e.g., potassium chloride (KCl) and/or sodium chloride (NaCl)); using electrochemical regeneration to convert the chloride to electrochemically regenerated product comprising the base (e.g., KOH and/or NaOH); and recycling at least a portion of the electrochemically regenerated product comprising the base to the capturing of the CO2 from the air. A system for carrying out the method is also provided.

Abstract: Embodiments of the present disclosure pertain to methods of treating or preventing a cancer in a subject by administering to the subject an immunogenic peptide and/or a nucleotide sequence that expresses the immunogenic peptide. Thereafter, the administered or expressed immunogenic peptide elicits an immune response against cells associated with the cancer. The immunogenic peptides contain a neoantigenic region and are expressed by chimeric nucleotide sequences derived from cells associated with the cancer. The chimeric nucleotide sequences have a higher prevalence in cancer cells when compared to non-cancer cells. Further embodiments pertain to compositions that include the immunogenic peptides of the present disclosure and/or a nucleotide sequences that express them. Additional embodiments pertain to methods of identifying immunogenic peptides by screening cells associated with a cancer for one or more chimeric nucleotide sequences; identifying peptides expressed by the chimeric nucleotide sequences; and selecting immunogenic peptides from the identified peptides.
