Abstract: The present disclosure generally relates to viral-based expression systems suitable for the production of molecule of interests in recombinant host cells. The disclosure particularly relates to nucleic acid constructs, such as expression vectors, containing a modified arterivirus genome or replicon RNA in which at least some of its original viral sequence has been deleted. Also included in the disclosure are viral-based expression vectors including one or more expression cassettes encoding heterologous polypeptides. In some embodiments, the expression cassettes are configured and positioned at defined locations on the viral genome so as to enable expression of the heterologous polypeptides in a tunable manner.

Abstract: An access point for facilitating connection of one or more wireless user devices to a first communications channel and operable to allocate resources to said user devices, the access point comprising a user device authenticator for determining whether a user device is in possession of pre-determined user device authentication information for obtaining access to the first communications channel, the access point having first and second modes of operation, wherein in the first mode of operation, the entirety of said resources is available for use by all user devices and in the second mode of operation, a portion of the resources is reserved for user devices that are in possession of the device authentication information; the access point being configured to switch the mode of operation when one or more mode switch criteria are met, wherein one of the mode switch criteria is based on the current demand for resources.

Abstract: A method of localising one or more scattering elements in a 3D environment, comprising (i) receiving, at an array of antennas, a signal sent from a transmitter and scattered towards the array by one or more scattering elements in the environment, (ii) modelling the signal as detected at each one of the antennas as a sum of individual signals scattered by the respective scattering elements, and (iii) collectively analysing the signals detected at each one of the antennas to identify the number and location(s) of the one or more scattering elements in the environment.

Abstract: Implants for the treatment of pelvic support conditions and methods of implementing the same. The implants comprise relatively soft, flexible bodies and relatively strong arms extending in predetermined orientation therefrom. Methods and devices for placing the implants minimize trauma to the pelvic floor and provide well-anchored support to pelvic organs without interfering with sexual or other bodily functions.

Abstract: In an embodiment a wireless device comprises a plurality of power amplifiers operable to generate signals for transmission over different frequency channels of a wireless network; an antenna system coupled to the plurality of power amplifiers configured to transmit the signals generated by the power amplifiers; a battery configured to store energy and to supply electrical energy to the plurality of power amplifiers; an energy harvesting unit configured to harvest energy from the environment surrounding the wireless device and transfer the harvested energy to the battery; a management unit configured to determine spectrum status information of the wireless network, select one or more channels of the wireless network, and determine the output power of the power amplifiers; and a configuration unit configured to control the efficiency and output power of each of the power amplifiers.

Abstract: An amplifier device comprises two modes of operation. In a first mode, the amplifier device operates in a wideband mode, whereas in a second mode the amplifier operates in a narrowband mode. Switching in the amplifier device provides antenna selection, in either mode. Control of mode and antenna selection is carried out with reference to a probability based optimisation, as to whether changing mode and/or antenna selection will improve efficiency. By that, the energy consumption associated with switching can be accommodated in the optimisation, thereby offering an improvement to efficiency.

Abstract: A system comprising a source node (11) and a relay node (15a, 15b 15c). The relay node senses a radio spectrum to provide first sensing data indicating the availability of a signal channel at the relay node. The source node senses the radio spectrum to provide second sensing data indicating the availability of the signal channel at the source node. The source node or relay node generates a channel availability parameter based on the first or second sensing data, respectively. The channel availability parameter comprises fewer bits of information than whichever of the first or second sensing data is used to generate the channel availability parameter. The source node determines whether to send message information to the relay node based on a sensing result obtained by combining the channel availability parameter with whichever one of the first and second sensing data is not used to generate the channel availability parameter.

Abstract: A method (300, 400, 500) of and a message service gateway (204) for controlling delivery of a message service provided by a service provider application (202) as a value-added service to an end user having a device with messaging capability. The method (300, 400, 500) comprises the steps of determining which one of predefined categories the service provider application (202) is, and controlling the delivery of the message service to the end user based on the determined category of the service provider application (202). A system comprising at least the above message service gateway (204), a service provider application (202), one or both of a Short Message Service Center (SMSC) (206) and a Multimedia Message Service Center (MMSC) (208), and an end user having a device with messaging capability is also provided.
