Abstract: A method for halogenation of an organic compound with a halogen from a waste source comprising a halogen containing polymer includes admixing waste source with the organic compound, a solvent, and an electrolyte, wherein the solvent swells and/or dissolves the halogen containing polymer in the waste source; and exposing the admixture to a negative voltage in an electrochemical cell comprising a cathode and an oppositely disposed anode. The halogen containing polymer is dehalogenated by the cathode to generate a halogen anion. The halogen anode is formed into a reactive halogen species by the anode.

Abstract: The disclosure provides, e.g., compositions, systems, and methods for targeting, editing, modifying, or manipulating a host cell's genome at one or more locations in a DNA sequence in a cell, tissue, or subject. Gene modifying systems for treating sickle cell disease (SCD) are described.

Abstract: A missile for a hydraulic fracturing system can include a high-pressure (HP) manifold, a low-pressure (LP) manifold, and a main manifold in between. The missile is configured to simultaneously fracture three or more wells. The HP manifold has multiple input channels, an output channel, and a main channel disposed in between. The LP manifold includes a LP input channel, multiple LP output channels, and a LP manifold in between.

Abstract: Provided is a portable X-ray system is equipped with an X-ray tube mounted on one end portion of the photography stand with a structure extending to a predetermined height and changing a photographing direction and a photographing angle in a portable body moved by an operator to change an installation location, the portable X-ray system including a body mounted on one end portion of the photography stand and configured to change the photographing angle and form an exterior of the X-ray tube, a collimator mounted on one side surface of the body and configured to adjust an X-ray photographing area and an X-ray photographing direction, and a rotating connection part mounted between the body and the collimator and configured to couple the collimator to be rotated based on one side surface of the body and transmit power and an electrical signal transmitted from the body to the collimator.

Abstract: Described herein are a secure system for sharing private data and related systems and methods for incentivizing and validating private data sharing. In some embodiments, private data providers may register to selectively share private data under controlled sharing conditions. The private data may be cryptographically secured using encryption information corresponding to one or more secure execution environments. To demonstrate to the private data providers that the secure execution environment is secure and trustworthy, attestations demonstrating the security of the secure execution environment may be stored in a distributed ledger (e.g., a public blockchain). Private data users that want access to shared private data may publish applications for operating on the private data to a secure execution environment and publish, in a distributed ledger, an indication that the application is available to receive private data.

Abstract: Various examples are directed to computer-implemented systems and methods for next generation financial account assistance. The method includes receiving a request from a primary account holder to provide a first limited permission for a secondary member to access an account of the primary account holder, and receiving a request from the primary account holder to provide a second limited permission for the secondary member to access the account of the primary account holder, where the second limited permission is activated based on one or more conditions selected by the primary account holder. In various embodiments, the method includes using the first limited permission to provide access to the secondary member to the account of the primary account holder for a first time period, and using the second limited permission to provide access to the secondary member to the account of the primary account holder for a second time period.

Abstract: The efficient and intuitive presentation, navigation, and selection of available AV information in a graphical user interface (GUI) that is displayed on a display apparatus of an AV system and controlled through user manipulation of a scrolling mechanism of a navigation and selection device of the AV system. Related AV information is organized as items within lists that correspond to various navigable fields of a status bar of the GUI during the GUI interactive mode. A highlighted navigable field of the status bar displays its list of related AV information and the items of the list are scrolled through the navigable field by a user causing the scrolling mechanism to move in a scroll. A different field of the status bar may be selected by the user moving the scrolling mechanism in a lateral movement.

Abstract: An adapter block apparatus for enabling conventional toy building blocks such as LEGO®, DUPLO®, Megablock® or other building blocks to form racetrack and train track structures for accommodating toy vehicles such as MatchBox® cars and Thomas The Tank Engine® trains. Adapter track blocks are configured to interconnect on the bottom thereof atop conventional building blocks. The top surface of each adapter track block is configured with either straight or curved surface contours, and with either a flat, horizontal path or a sloped path, to provide a longitudinal, medial path for accommodating travel of toy racing cars and trains.

Abstract: A method and apparatus for adjusting font size in an electronic program guide display are provided. A multiple channel broadcasting system generates an electronic program guide identifying channels and corresponding programs in a broadcasting system. The broadcast system determines a number of characters to be displayed in an area of an electronic program guide. The broadcast system determines a number of display pixels available for display of the characters. The broadcast system adjusts the font size of the characters to display the number of characters within the number of pixels available.
