Wie bekommen wir Investitionen in moderne Breitbandnetze?: Podiumsdiskussion mit Roland Berger, René Obermann, Lars-Hendrik Röller und Hans-Werner Sinn / moderiert von Roland Tichy

In der abschließenden Podiumsdiskussion, die sich noch einmal mit dem Themenbereich IKT-Infrastruktur befasst, diskutieren Roland Berger, René Obermann, Lars-Hendrik Röller, Hans-Werner Sinn und Roland Tichy, „wie wir Investitionen in moderne Breitbandnetze bekommen“. Dabei ging es vor allem um die Frage, ob und wie sich eine geänderte Regulierung als Konjunkturprogramm erweisen kann, wenn sie den derzeitigen Investitionsstau in der deutschen IKT-Netzinfrastruktur beheben kann. Vieles deutet darauf hin, dass der Staat durch entsprechende Rahmensetzungen private Zukunftsinvestitionen anregen kann, die seinen eigenen Haushalt schonen. Nach Ansicht der Podiumsteilnehmer erfordert der Ausbau der Breitbandnetze keine großen zusätzlichen Ausgaben durch die Bundesregierung, sondern eine „intelligente Regulierung, die die Investitionsaktivitäten der Telekommunikationsunternehmen stimuliert“. Dadurch könnten bei den Nutzern aus allen Wirtschaftsbereichen, gerade auch aus dem Mittelstand, wichtige Beschäftigungs- und Produktivitätssteigerungseffekte entstehen.Breitbandkommunikation, Investition, Institutionelle Infrastruktur, Deutschland

Error-analysis and comparison to analytical models of numerical waveforms produced by the NRAR Collaboration

The Numerical-Relativity-Analytical-Relativity (NRAR) collaboration is a joint effort between members of the numerical relativity, analytical relativity and gravitational-wave data analysis communities. The goal of the NRAR collaboration is to produce numerical-relativity simulations of compact binaries and use them to develop accurate analytical templates for the LIGO/Virgo Collaboration to use in detecting gravitational-wave signals and extracting astrophysical information from them. We describe the results of the first stage of the NRAR project, which focused on producing an initial set of numerical waveforms from binary black holes with moderate mass ratios and spins, as well as one non-spinning binary configuration which has a mass ratio of 10. All of the numerical waveforms are analysed in a uniform and consistent manner, with numerical errors evaluated using an analysis code created by members of the NRAR collaboration. We compare previously-calibrated, non-precessing analytical waveforms, notably the effective-one-body (EOB) and phenomenological template families, to the newly-produced numerical waveforms. We find that when the binary's total mass is ~100-200 solar masses, current EOB and phenomenological models of spinning, non-precessing binary waveforms have overlaps above 99% (for advanced LIGO) with all of the non-precessing-binary numerical waveforms with mass ratios <= 4, when maximizing over binary parameters. This implies that the loss of event rate due to modelling error is below 3%. Moreover, the non-spinning EOB waveforms previously calibrated to five non-spinning waveforms with mass ratio smaller than 6 have overlaps above 99.7% with the numerical waveform with a mass ratio of 10, without even maximizing on the binary parameters.Comment: 51 pages, 10 figures; published versio

Familial hypercholesterolaemia in children and adolescents from 48 countries: a cross-sectional study

Background: Approximately 450 000 children are born with familial hypercholesterolaemia worldwide every year, yet only 2·1% of adults with familial hypercholesterolaemia were diagnosed before age 18 years via current diagnostic approaches, which are derived from observations in adults. We aimed to characterise children and adolescents with heterozygous familial hypercholesterolaemia (HeFH) and understand current approaches to the identification and management of familial hypercholesterolaemia to inform future public health strategies. Methods: For this cross-sectional study, we assessed children and adolescents younger than 18 years with a clinical or genetic diagnosis of HeFH at the time of entry into the Familial Hypercholesterolaemia Studies Collaboration (FHSC) registry between Oct 1, 2015, and Jan 31, 2021. Data in the registry were collected from 55 regional or national registries in 48 countries. Diagnoses relying on self-reported history of familial hypercholesterolaemia and suspected secondary hypercholesterolaemia were excluded from the registry; people with untreated LDL cholesterol (LDL-C) of at least 13·0 mmol/L were excluded from this study. Data were assessed overall and by WHO region, World Bank country income status, age, diagnostic criteria, and index-case status. The main outcome of this study was to assess current identification and management of children and adolescents with familial hypercholesterolaemia. Findings: Of 63 093 individuals in the FHSC registry, 11 848 (18·8%) were children or adolescents younger than 18 years with HeFH and were included in this study; 5756 (50·2%) of 11 476 included individuals were female and 5720 (49·8%) were male. Sex data were missing for 372 (3·1%) of 11 848 individuals. Median age at registry entry was 9·6 years (IQR 5·8-13·2). 10 099 (89·9%) of 11 235 included individuals had a final genetically confirmed diagnosis of familial hypercholesterolaemia and 1136 (10·1%) had a clinical diagnosis. Genetically confirmed diagnosis data or clinical diagnosis data were missing for 613 (5·2%) of 11 848 individuals. Genetic diagnosis was more common in children and adolescents from high-income countries (9427 [92·4%] of 10 202) than in children and adolescents from non-high-income countries (199 [48·0%] of 415). 3414 (31·6%) of 10 804 children or adolescents were index cases. Familial-hypercholesterolaemia-related physical signs, cardiovascular risk factors, and cardiovascular disease were uncommon, but were more common in non-high-income countries. 7557 (72·4%) of 10 428 included children or adolescents were not taking lipid-lowering medication (LLM) and had a median LDL-C of 5·00 mmol/L (IQR 4·05-6·08). Compared with genetic diagnosis, the use of unadapted clinical criteria intended for use in adults and reliant on more extreme phenotypes could result in 50-75% of children and adolescents with familial hypercholesterolaemia not being identified. Interpretation: Clinical characteristics observed in adults with familial hypercholesterolaemia are uncommon in children and adolescents with familial hypercholesterolaemia, hence detection in this age group relies on measurement of LDL-C and genetic confirmation. Where genetic testing is unavailable, increased availability and use of LDL-C measurements in the first few years of life could help reduce the current gap between prevalence and detection, enabling increased use of combination LLM to reach recommended LDL-C targets early in life

Four-gender systems in Indo-European

A long-established tenet of Indo-European linguistics says that grammatical gender systems all along the history of this language phylum were maximally tripartite and generally tended toward a reduction of gender contrasts. In this article, we shall show that this widely-held idea overlooks the existence of four-gender systems in a substantial part of the Romance language family, a fact that has in turn gone unnoticed so far. We shall provide an analysis of the relevant Romance data, a sketchy comparison with other four-gender systems described in linguistic typological research, and a detailed reconstruction of how the gender systems in question might have developed in the Latin-Romance transition
