Abstract: A mobile device performs authentication with blinded tokens and swaps its international mobile subscriber identity (IMSI) value. For authentication with blinded tokens, the mobile device generates a blinded token and provides it to a server to encrypt. To redeem the token, the mobile device unblinds the encrypted blinded token and provides it to the server along with a public key. To complete authentication, the mobile device receives, from the server, a nonce encrypted with the public key and decrypts the nonce with a private key. For swapping its IMSI value, the mobile device retrieves two eSIM profiles with corresponding IMSI values and configures the first of the two profiles as active. In response to a trigger, the mobile device changes the active profile from the first to the second, swaps the first IMSI value with a new IMSI value, and changes the active profile back to the first profile.

Abstract: This invention relates to a burner (1) for burning a suspension of solid fuel in oxygen containing gas. A portion of the suspension is passed through a first conduit (10) which contains a bluff body (12) and helical vanes to impart turbulence and swirl to the suspension. A further portion of the suspension is passed through a second conduit (40) which is coaxial with the first conduit. Means for varying the relative sizes of each portion are provided. The arrangement allows improved fuel/air mixing, flame shape, heat transfer and control of NOx emissions.

Abstract: The present invention provides a novel and unique device, method and system that detects thiocyanate in seawater with the halide ions present that can be provided in a hand-portable device that offers detection limits to 1-2 ppb which at least twice as sensitive as the nearest known device in the current state of the art. The sensor is also sensitive to nitrate ions (NO3?) in seawater at similar ppb concentrations as thiocyanate.

Abstract: Ursodeoxycholic acid (UDCA) is a bile acid with demonstrated anti-apoptotic activity in both in vitro and in vivo models. Water-soluble prodrugs of UDCA for use in indications where intravenous administration of UDCA may be preferable, such as reducing damage from stroke or acute kidney injury, are disclosed. The disclosed prodrugs showed significant anti-apoptotic activity in a series of in vitro assays.

Abstract: An apparatus for holding radioactive objects includes a base and a central pillar extending upwardly between a bottom end coupled to the base and a top end above the base. A plurality of inner segments are spaced around the central pillar, and a plurality of outer segments are spaced around the inner segments to form pairs. The inner segments, the outer segments and the central pillar may be coupled together to permit limited radial movement of at least one of the segments of each pair. Each pair may define a generally vertical, object-receiving channel arranged between the inner and outer segment of the pair. The segments of each pair may be adapted to bear against an object in the channel of the pair to laterally restrain the object and facilitate heat transfer from the object.

The apparatus (100) includes a side blow device (110) having a blow pin assembly (112) and an inner support assembly (114). The blow pin assembly (112) includes a blow pin driver (116) formed as a cylinder (118). The blow pin assembly (112) also includes a blow pin (122) connected to a shuttle system (124) which, in turn, is connected to the cylinder (118). The shuttle system (124) operates so as to move the blow pin (122) in a linear manner. The inner support assembly (114) includes an inner support driver (138) connected to an extender (144). The inner support driver (138) extends and retracts the extender (144) for raising and lowering the inner support (142). The blow pin (122) is positioned on the shuttle system (124) so that the pin (122) can be shuttled in and out of a parison during the blow molding process.

Abstract: A dental shaping strip includes a base portion and a shaping portion. The base portion has a first base surface and a second base surface facing in an opposite direction from the first base surface. The first and second base surfaces have prescribed longitudinal lengths and prescribed widths transverse to the prescribed longitudinal lengths. The shaping portion is connected to a longitudinal edge of the base portion. The shaping portion has a first shaping surface connected to the first base surface, with at least part of the first shaping surface being abrasive. The first and second base surfaces are at least partially non-abrasive. Preferably, the first shaping surface and the first base surface diverge from each other as they approach longitudinal free edges of the dental shaping strip. Preferably, the first and second base surfaces are non-abrasive along their prescribed longitudinal lengths.

Abstract: An air intake for a supersonic air-breathing flight vehicle introduces or injects fluid in order to create predetermined regions of separated flow and an attendant fluid shear layer. This shear layer forms an aerodynamic boundary for the capture flow with a profile determined and optimised by appropriate injection of fluid. The aerodynamic boundary so generated replaces mechanically moveable solid surfaces used to vary the geometry of prior-art intakes. Use of an introduced or injected fluid can provide an advantage of a variable geometry, but with reduced weight and reduced mechanical complexity. In some embodiments, the injection of fluid has the effect of re-energizing any ingested boundary layer, thus obviating the conventional requirement for a bleed system to provide boundary layer control.
