  • Publication number: 20220315951
    Abstract: The invention relates to an infectious arenavirus particle that is engineered to contain a genome with the ability to amplify and express its genetic information in infected cells but unable to produce further infectious progeny particles in normal, not genetically engineered cells. One or more of the four arenavirus open reading frames glycoprotein (GP), nucleoprotein (NP), matrix protein Z and RNA-dependent RNA polymerase L are removed or mutated to prevent replication in normal cells but still allowing gene expression in arenavirus vector-infected cells, and foreign genes coding for an antigen or other protein of interest or nucleic acids modulating host gene expression are expressed under control of the arenavirus promoters, internal ribosome entry sites or under control of regulatory elements that can be read by the viral RNA-dependent RNA polymerase, cellular RNA polymerase I, RNA polymerase II or RNA polymerase III.

  • Publication number: 20220275432
    Abstract: The present invention relates to a method for distinguishing a first nucleic acid sequence from a second nucleic acid sequence by electrophoresis. The first nucleic acid comprises a first common sequence tract, a variable sequence tract and a second common sequence tract and the second nucleic acid comprises a first common sequence tract, optionally an variable sequence tract and a second common sequence tract. The first and the second nucleic acid sequence is contacted with a probe sequence that is reverse complementary to the first and second common sequence tract under conditions allowing the hybridization of the probe sequence to the first and second nucleic acid sequence, thereby forming a first probe hybrid and a second probe hybrid. Subsequently, the first and second probe hybrids are submitted to electrophoresis to detect the electrophoretic mobility of the first and second probe hybrid.

  • Patent number: 11395090
    Abstract: An illustrative method for estimating a direct-to-reverberant ratio of a sound signal is described, wherein the direct-to-reverberant ratio is indicative of a ratio between direct sound received from a sound source and reverberated sound received from reflections in an environment of the sound source. The method includes determining a first energy value of a sound signal for a first time frame; assigning to an onset value of the first time frame a positive value, if the difference of the first energy value of the first time frame and a second energy value of a preceding second time frame is greater than a threshold, and a zero value otherwise; and determining the direct-to-reverberant ratio by providing an onset signal comprising the onset value to a machine learning algorithm, which has been trained to determine the direct-to-reverberant ratio based on the onset signal.

  • Publication number: 20220107256
    Abstract: A model-order reduction system and methods are described for providing a fast fluid flow simulation model of fluid flow in a conduit such as a blood vessel with stenosis. A first method is described for generating a reduced generic numerical model (20) for predicting fluid flow characteristics of fluid flowing through a subject conduit (7?). In steps 11, 12 and 13, geometric and fluid-flow parameter data are derived from CT image scans for each sampled conduit (7) in a reference set. A 3D model is generated (13) for each sampled conduit (7). The geometric parameter data, the 3D model and the fluid flow parameter data are used to generate solutions to fluid dynamics (such as the Navier-Stokes) equations for each sampled conduit (7), and a full order model is created comprising the geometric parameters data, the fluid flow parameter data and the Navier Stokes solutions.

  • Publication number: 20220092401
    Abstract: Circuits for generating random weights, such as for neuromorphic processors, include a first voltage node (VDD) for providing a supply voltage for the circuit and a second voltage node (VG) at a given electric potential. A first circuit element (Ma1) has a first electric current carrier concentration for outputting a first circuit element output signal. A second circuit element (Mb1) has a second electric current carrier concentration for outputting a second circuit element output signal. The first and second circuit elements are located between the first and second voltage nodes, which have a given voltage difference therebetween. The first and second circuit element output signals are different due to the first and second electric carrier concentrations being mismatched. The circuit further includes a subtraction unit configured to generate a respective random weight, which is represented by a difference between the first and second circuit element output signals.

  • Patent number: 11246517
    Abstract: A spectrophotometric apparatus for determining optical parameters in a scattering medium based on the measurement of attenuation of light propagating through said medium by diffusion. To eliminate the detrimental effect of light being guided in an intermediate optical layer between a surface of the medium and a contact surface of the apparatus, either a multitude of optical barriers may be formed in the contact surface or the angular range over which light is emitted or received by the apparatus may be limited by appropriate means. With both of these alternative approaches, light propagation in the intermediate layer can be suppressed, leading to increased measurement accuracy. This is particularly beneficial for building an oximeter with improved precision. Further aspects include features for improving the applicability of the apparatus on curved surfaces such as the strongly curved skulls of neonates.
