Abstract: The present invention regards recombinant HVT (rHVT) constructs, useful as multivalent vector vaccine for poultry. The rHVT comprise 4 heterologous genes from poultry pathogens: the VP2 gene from IBDV, the F gene from NDV, and the gD and gI genes from ILTV. The VP2 and F genes are inserted in the Us genome region of the rHVT. The gD-gI genes are inserted in the UL genome region, either between UL44 and UL45, or between UL45 and UL46. The rHVTs proved to be genetically stable in vitro and in vivo, and expressed all inserted genes well enough to induce protective immunity in vaccinated poultry against IBDV, NDV, and ILTV.

Abstract: The present invention relates to vaccines against influenza virus infection or disease for targets with pre-existing antibodies against influenza virus HA head domain. The invention regards a recombinant vector expressing a HA stem polypeptide, a vaccine comprising the vector or a host cell with said vector, uses of the vector, the host cell, or the vaccine, and methods for reducing influenza virus infection or disease. The recombinant vector can be a nucleic acid such as a eukaryotic expression plasmid or an RNA, a virus, or a replicon particle (RP). This vaccination allows for the induction of an early- and effective immune-response against Influenza virus induced infection or disease, not hindered by pre-existing anti-HA head domain antibodies.

Abstract: The present invention provides recombinant vectors encoding a chimeric coronavirus spike protein. The present invention further provides new immunogenic compositions and vaccines comprising these recombinant vectors. Methods of administering these immunogenic compositions and vaccines to animal subjects, including humans, felines, and avians, to protect them against coronaviruses also are included. Methods of making the immunogenic compositions and vaccines alone or in combinations with other protective agents are provided too.

Abstract: The present invention describes a recombinant herpesvirus of turkeys (rHVT) that can be used as a vector vaccine for poultry against infection and disease from multiple poultry pathogens. Specifically the rHVT expresses an infectious bursal disease virus (IBDV) viral protein 2 (VP2) gene and a Newcastle disease virus (NDV) fusion (F) protein gene from a first and a second expression cassette inserted in the unique small (Us) region, and expresses an avian influenza vims (AIV) haemagglutinin (HA) gene from a third expression cassette inserted in the unique long (UL) region of the genome of said rHVT either between the UL40 and UL41 genes, or between the UL44 and UL45 genes. This rHVT can be used to vaccinate poultry against MDV, IBDV, NDV and AIV.

Abstract: Methods, apparatus and computer programs for controlling the output of a transmission point. A method for controlling the output of a transmission point for a wireless communications network. The method comprises: determining an average output power of the transmission point over a period of time; comparing the average output power to an output power reference value; and allocating data, to be transmitted by the transmission point to one or more wireless devices, to a pool of radio resources. The pool of radio resources is adjusted as a function of the comparison between the average output power and the output power reference value.

Abstract: Embodiments include methods of operating a user equipment (UE) in a serving cell provided by a base station in a cellular communications network. These embodiments include establishing a Radio Resource Control (RRC) connection with the base station, such that the UE is operating in an RRC Connected state according to a first value of a parameter (e.g., a time alignment timer value) affecting the UE's uplink synchronization with the serving cell. These embodiments also include initiating a reconfiguration of the RRC connection towards the base station and, in response to initiating the reconfiguration, receiving from the base station a second value of the parameter affecting the UE's uplink synchronization with the serving cell. These embodiments also include operating in an RRC Connected state according to the second value of the parameter. Other embodiments include UEs configured to perform operations corresponding to these methods.

Abstract: Systems and methods for selectively enabling Robust Header Compression (RoHC) for Voice over Internet Protocol (VoIP) calls in a cellular communications network are disclosed. In one embodiment, a data radio bearer for a VoIP call is established between a base station and a mobile terminal. During the VoIP call, a radio frequency parameter for the data radio bearer is monitored. When the radio frequency parameter for the data radio bearer satisfies a predefined coverage-based condition, the base station enables RoHC for the VoIP call. In one preferred embodiment, the radio frequency parameter is a Signal-to-Interference-plus-Noise Ratio (SINR) for the data radio bearer for the VoIP call, and the predefined coverage-based condition is a predefined SINR threshold below which the base station enables RoHC. By enabling RoHC in this manner, RoHC resources are selectively made available for those VoIP calls that will benefit most from increased cell coverage provided by RoHC.

Abstract: It is presented a method for releasing semi-persistent scheduling, SPS, for a wireless device. The method is performed in a network node and comprising the steps of: transmitting an SPS release message to the wireless device to release uplink SPS; starting a timer; when a first condition is true, transmitting a grant for uplink transmission to the wireless device, the first condition being true when the timer expires and/or a scheduling request has been received from the wireless device; receiving a data type indication from the wireless device; and determining that an SPS release message has been correctly received by the wireless device when a scheduling request has been received from the wireless device, the grant has been transmitted and the data type indication indicates only voice over internet protocol, VoIP, data from the wireless device.
