    Abstract Virtual testing and validation are building blocks in the development of autonomous systems, in particular autonomous driving. Perception sensor models gained more attention to cover the entire tool chain of the sense-plan-act cycle, in a realistic test setup. In the literature or state-of-the-art software tools various kinds of lidar sensor models are available. We present a point cloud lidar sensor model, based on ray tracing, developed for a modular software architecture, which can be used stand-alone. The model is highly parametrizable and designed as a toolbox to simulate different kinds of lidar sensors. It is linked to an infrared material database to incorporate physical sensor effects introduced by the ray-surface interaction. The maximum detectable range depends on the material reflectivity, which can be covered with this approach. The angular dependence and maximum range for different Lambertian target materials are studied. Point clouds from a scene in an urban street environment are compared for different sensor parameters.

    Abstract The main objective of this article is to provide angle-dependent spectral reflectance measurements of various materials in the near infrared spectrum. In contrast to already existing reflectance libraries, e.g., NASA ECOSTRESS and Aster reflectance libraries, which consider only perpendicular reflectance measurements, the presented dataset includes angular resolution of the material reflectance. To conduct the angle-dependent spectral reflectance material measurements, a new measurement device based on a 945 nm time-of-flight camera is used, which was calibrated using Lambertian targets with defined reflectance values at 10, 50, and 95%. The spectral reflectance material measurements are taken for an angle range of 0° to 80° with 10° incremental steps and stored in table format. The developed dataset is categorized with a novel material classification, divided into four different levels of detail considering material properties and distinguishing predominantly between mutually exclusive material classes (level 1) and material types (level 2). The dataset is published open access on the open repository Zenodo with record number 7467552 and version 1.0.1 [1]. Currently, the dataset contains 283 measurements and is continuously extended in new versions on Zenodo.

    Abstract This presentation dealt with the contributions of German virologists in the rapid development of virology following the Loeffler-Frosch era. Thereby, only research was included which was undertaken within German institutions, even though guest scientists from other countries or international cooperative efforts have in some cases contributed to the work. Contributions to the field of veterinary virology were not considered here, since this topic was treated separately during this centennial symposium. The overview includes contributions of the very early period when interest was focussed mainly on the determination of the physicochemical properties of the fast growing number of newly detected viruses, and of the pioneering period when fundamental discoveries of the nature of viruses were made. The concepts that derived from those studies made the development of modern virology possible. Some highlights of the present period were presented describing the findings of selected virus families. This part was followed by a description of the results which were relevant to problems of how viruses become pathogens, and the role of the immune response to virus infections. Finally, attention was drawn to the contributions of molecular studies which became important not only for the field of virology but also for life sciences in general.

    Title translation Influenza, a special form of zoonosis.
    Abstract Findings based on molecular genetics and phylogeny indicate that avian species represent an important reservoir for influenza viruses and that virus strains of man and different mammals originated from avian influenza virus ancestors. In contrast to infectious agents causing classical zoonoses, influenza viruses have to alter their genetic make up in order to change their host range. The special, segmented structure of the viral RNA allows an exchange of gene(s) between two different influenza viruses (reassortment) resulting in viruses with different combinations of genome segments and thereby creating new biological properties. Under the selective pressure of the new host the most adapted virus variants will succeed which arose from a genetically heterogeneous virus population with additional mutations. In particular mutations of the genes encoding the polymerase complex (mutator mutations) would be advantageous for rapid adaptation in a hostile environment. The generation of influenza viruses capable of overcoming the species barrier is a rare event since only virus variants will succeed which are genetically stable and transmissible and which replicate efficiently in the new host. It is considered likely that pigs act as intermediate hosts for adaptation of avian viruses to man.

    Abstract Actinomycin D (5 γ/ml) inhibits the synthesis of fowl plague virus RNA, S-antigen, hemagglutinin, neuraminidase and infectious particles. Even high concentrations (40 γ/ml) of the antibiotic do not inhibit the synthesis of the corresponding components of NDV. Although purified suspensions of these viruses can be inactivated by actinomycin in the presence of light, this photoeffect does not play an important role in the inhibition of fowl plague virus synthesis. If in the case of fowl plague virus actinomycin is added to tissue cultures at a time after infection when viral RNA synthesis has already started (1½—2 hours p. i.) further synthesis of viral RNA is stopped, while the S-antigen titer continues to rise.

    Abstract Influenza viruses, like other viruses, must exhibit a genome constellation, which permits optimal virus reproduction in a given host. Besides this prerequisite the influenza virus haemagglutinin glycoprotein (HA) has been shown to be an essential determinant for pathogenicity. HA, which is synthesized as a precursor molecule, is activated by posttranslational cleavage by host proteases to obtain its full biological properties. Proteolytic activation is therefore indispensable for effective virus spread in the infected host and thus for pathogenicity. HA of the highly pathogenic avian influenza viruses inducing a systemic infection in birds is cleaved in a broad range of different host cells. On the other hand, HA of all mammalian viruses and the nonpathogenic avian strains, which cause local infection, exhibit a restricted cleavability. The prime determinant for these differences has been found to be the structure of the cleavage site. This concept was corroborated on virus mutants adapted in vitro to a new host.

    Abstract Treatment of host cells with Concanavalin A prevents the assembly or release of fowl plague virus from chick fibroblasts and inhibits fusion of BHK cells by the paramyxovirus SV5. Metabolic events of the host cells are not greatly impaired during the early phase of infection. There is evidence that the carbohydrate moiety of the Con A receptor of fowl plague virus is associated with the viral neuraminidase.
