Abstract

The invention relates to an amorphous calcium phosphate/bioactive glass composite material (ACP/BG). This composite material possesses both the short-time ion release capability of ACP as well as the long-time ion release of BG and thus (i) efficiently remineralizes damaged enamel, and (ii) induces the formation of a new HA layer onto enamel and dentin surface. The ACP/BG composite material is obtained by embedding BG particles in a matrix of ACP nanoparticles in order to maximize homogenization between the two components and to produce a composite with high uniformity from the macro- to the nano-scale. This has been achieved with a process that includes a step of precipitating ACP onto BG particles. The BG particles can be nano-, micro-, or macro-particles. The particles can also be porous or mesoporous The invention relates also to the use of the composite material of the invention for use in the prevention of dental demineralization and to boost remineralization. In other words, the composite material here disclosed is used as remineralizing agent thanks to its ability to restore the structure and preserve the mechanical properties of dental hard tissues by releasing Ca2+and PO4 3− ions, thereby mimicking the spontaneous remineralization process induced by saliva. The composite material can also be used for bone regeneration.

Abstract

To monitor infection by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and successful vaccination against coronavirus disease 2019 (COVID-19), the kinetics of neutralizing or blocking anti-SARS-CoV-2 antibody titers need to be assessed. Here, we report the development of a quick and inexpensive surrogate SARS-CoV-2 blocking assay (SUBA) using immobilized recombinant human ACE-2 (hACE-2, ACE-2) and human cells expressing the native form of surface SARS-CoV-2 spike protein. Spike protein-expressing cells bound to hACE-2 in the absence or presence of blocking antibodies were quantified by measuring the optical density of cell-associated crystal violet in a spectrophotometer. The advantages are that SUBA is a fast and inexpensive assay which does not require biosafety level 2- or 3- approved laboratories. Most importantly, SUBA detects blocking antibodies against the native trimeric cell-bound SARS-CoV-2 spike protein and can quickly be adjusted to quickly pre- screen already approved therapeutic antibodies or sera from vaccinated individuals for their ACE-2 blocking activities against any emerging SARS-CoV-2 variants.

Abstract

A more efficient rendering of audio objects, which allows 3D panning, is achieved by performing the panning into two stages, namely at least one horizontal in-layer panning leading to a first virtual (speaker) position and a second virtual or real (speaker) position, which is vertically offset, and another panning vertically between the two positions. Although acting in such a manner seems to increase the computational complexity, this staged processing increases, in fact, the stability of the rendering and the location of the intended virtual position. Moreover, the staged processing, enables to perform, according to an embodiment, the panning by use of amplitude panning gains only, i.e. phase processing is not necessary, thereby rendering the computational complexity low. Even further, the rendering is flexible with respect to applicability to a variety of loudspeaker setups.

Abstract

The present disclosure relates to an apparatus and a method for providing a plurality of motion vectors related to an image coded in a bitstream, comprising obtaining a set of sample positions within the image, obtaining respective motion vectors associated with the set of sample positions, deriving an additional motion vector based on information coded in the bitstream, determining an additional sample position located within a triangle, which is formed by three sample positions of the set of sample positions, based on the respective motion vectors associated with the three sample positions, the triangle not including any other sample position of the set, adding the additional sample position to the set of sample positions, and associating the derived additional motion vector with the additional sample position. Such method and apparatus provide for an efficient motion flow compression and reconstruction enabling to recover some sample positions without signaling them in the bitstream.

Abstract

The invention relates to an electrode structure for guiding and, for example, splitting a charged particle beam, for example an electron beam, along a longitudinal path, having multipolar electrode assemblies which are mutually spaced along the longitudinal path and which comprise DC voltage electrodes. The electrode assemblies are designed to generate static multipolar fields which are centered about the path on transversal planes oriented perpendicularly to the longitudinal path, wherein the field strength of each of the static multipolar fields on the transversal planes has a local minimum at the location of the path, and the field strength increases as the distance to the location of the path increases. Field directions of the static multipolar fields vary periodically along the path with a period length such that the particles propagating along the path are exposed to a non-homogenous electric alternating field on the basis of the inherent movement of the particles and are subjected to a transversal restoring force in the direction of the longitudinal path, averaged over time.

Abstract

A method for the additive manufacture of a circuit carrier is described. Firstly, a ceramic substrate (16) and a metallic powder (17) are provided. Then, a conductor structure (15) connected to the ceramic substrate (16) in an integrally bonded manner is generated by applying a powder layer (P1) of the metallic powder (17) to the ceramic substrate (16) and selectively melting said powder layer in order to produce a first metallisation layer (M1), and by applying at least one further powder layer (P2, P3) of the metallic powder (17) and selectively melting said further powder layer in order to produce at least one further metallisation layer (M2, M3). A circuit carrier is additionally described.
