Abstract: The present subject matter is directed to a system and method for producing carbon and syngas from carbon dioxide (CO2). The system includes a first reactor (7) for producing solid carbon (15) from a feed including CO2 and a volatile organic compound such as methane (1), and a second reactor (20) for producing syngas. Reactions in the first reactor (7) are conducted in a limited oxygen atmosphere. The second reactor (20) can use dry reforming, steam reforming, and/or partial oxidation reforming to produce the syngas (22).

Abstract: A method to regenerate and reactivate catalysts used for a carbon and syngas production reaction including a DRM or CARGEN reaction is developed. Carbon dioxide (CO2) is used as the regeneration and activation media. This method of a single step regeneration and activation using CO2 is more effective than the existing conventional two-step process that includes separate reduction and oxidation steps. This method produces pure carbon monoxide (CO) as a byproduct from the regeneration process by utilizing CO2 and carbon.

Abstract: The main objective of Certificate Transparency (CT) is to detect mis-issued certificates or rouge certificate authorities. It has been observed that phishing sites have been increasingly acquiring certificates to look more legitimate and reach more victims, thus providing an opportunity to predict phishing domains early. The present disclosure provides systems and methods for early detection of phishing and benign domain traces in CT logs. The provided system may predict phishing domains early even before content is available via time-, issuer-, and certificate-based characteristics that are used to identify sets of CT-based inexpensive and novel features. The CT-features are augmented with other features including passive DNS (pDNS) and domain-based lexical features.

Abstract: A shape-memory alloy actuated switch (SMAAS) is provided that enables the stable switching of two separate circuits. The presently disclosed SMAAS includes a substrate, one or more electrical contacts attached to the substrate for connecting to load circuits, and one or more electrically conductive elements for selectively connecting the one or more electrical contacts. The disclosed SMAAS also includes one or more shape-memory alloy actuators attached to the substrate. The one or more shape-memory alloy actuators are configured to move the one or more electrically conductive elements. The shape-memory alloy actuators are self-heated by passing current through the shape-memory alloy material. The disclosed SMAAS may also include electrical contacts to connect an external control current to the shape-memory alloy material. In some examples, the provided SMAAS includes one or more retention mechanisms to prevent movement of the electrically conductive elements after actuation.

Abstract: A transrectal probe manipulator system includes a probe comprising a biopsy needle and a manipulator. The manipulator includes a base including first and second base support shafts on a base body, a main frame, and a mounting plate. A lower end of the main frame is rotatably connected to the base through a first shaft to define a first degree of freedom. The mounting plate includes first and second mounting plate support shafts and a probe receiver, and is rotatably connected to the main frame through a second shaft to define a second degree of freedom. The probe receiver is rotatable about a central axis to define a third degree of freedom, and linearly moveable along the central axis to define a fourth degree of freedom. The probe is secured to the probe receiver. The manipulator is driven by cables which are attached to the shafts in an actuation assembly.

Abstract: A smart diaper system and methods for making the same. The system includes a diaper, an embedded sensor array, fixed to the diaper, including at least one sensor configured to detect a stimuli and a wireless transmission module operably connected to the embedded sensor array, configured to transmit a signal to a peripheral device. Additionally, in response to detecting a stimuli, the embedded sensor array communicates with the wireless transmission module to transmit a signal to the peripheral device corresponding to the detected stimuli. The method for manufacturing a smart diaper system includes providing a diaper, providing an embedded sensor array, including at least one sensor configured to detect a stimuli. Additionally, the embedded sensor array consists of screen printed sensors printed directly on a thermal transfer substrate and the thermal transfer substrate featuring the embedded sensor array becomes a fixed integral part of the diaper.
