Quantitative paleoclimate reconstructions in the European region based on multiple proxies
(2023-03-31)The Earth’s climate system is highly dimensional and has to be described with the help of probabilities. Such probability descriptions can be estimated from measured data. Relatively large-scale instrumental records, ... -
Plant mitochondrial RNA editing factors can perform targeted C-to-U editing of nuclear transcripts in human cells
(2022-09-15)RNA editing processes are strikingly different in animals and plants. Up to thousands of specific cytidines are converted into uridines in plant chloroplasts and mitochondria whereas up to millions of adenosines are converted ... -
German Geographical Research on North America: A Bibliography with Comments and Annotations
(1992)The 27th International Geographical Congress in Washington, D.C., 1992 is the first geographical congress to take place in the United States for 40 years. This event and the 40th anniversaiy of the readmittance of Germany ... -
Die Vegetationskarte des Gebietes von El Bolsón, Prov. Río Negro, und ihre Anwendung in der Landnutzungsplanung
(1979)Ziel der vorliegenden Studie ist es, an Hand eines Kartenausschnittes einen Überblick über die Vegetationszonierung zu geben, die durch das Klimagefälle am östlichen Andenrand und durch die Höhenstufen bedingt ist. Zugleich ... -
Spectroscopic Gas Sensor Based on a Fiber Fabry-Perot Cavity
(2022-10-17)Optical spectroscopic sensors are powerful tools for analyzing gas mixtures in industrial and scientific applications. Whilst highly sensitive spectrometers tend to have a large footprint, miniaturized optical devices ... -
The application of dendrometers to alpine dwarf shrubs – a case study to investigate stem growth responses to environmental conditions
(2022-04-05)Considering the recent widespread greening and browning trends associated with shrubs in arctic–alpine ecosystems, further understanding of how these shrubs respond in a rapidly changing environment is of crucial ... -
Fluctuation-Dissipation Relation for a Bose-Einstein Condensate of Photons
(2023-01-20)For equilibrium systems, the magnitude of thermal fluctuations is closely linked to the dissipative response to external perturbations. This fluctuation-dissipation relation has been described for material particles in a ... -
Forschungen in Chile
(1956)Die drei Forschungen haben enge Berührungspunkte und ergänzen sich zu einem wichtigen Beitrag zur Biogeographie, Klimatologie, Pflanzenökologie und Landwirtschaft von Chile. <em> J. Schmithüsen</em> analysiert die Verbreitung ... -
Expanding the understanding of peptidoglycan turnover in Chlamydiae: biosynthesis, degradation and recycling
(2023-03-29)The obligate intracellular chlamydiae evolved mechanisms to persist inside their host and to evade the host immune system, making them intriguing and highly successful pathogens. This work aimed to asses how these strategies ... -
Identification of Pharmacogenomic and Functional Biomarkers for Antidepressant Treatment Outcome in Patients-Derived Lymphoblastoid Cell Lines
(2023-03-29)Major depression is the most prevalent mental disorder worldwide. Pharmacological management of the disease is considered a cornerstone in treatment guidelines adopted by many industrialized countries. However, response ... -
Multi-taxic palaeohistological analyses of vertebrates originating from the Upper Triassic at Krasiejów (SW Poland) and an assessment of growth patterns in comparative taxa
(2023-03-29)Palaeohistology is a good source of information about the biology of extinct animals as it provides insight into skeletochronology, metabolic rate or mode of life. The Polish Krasiejów locality recovers a unique Upper ... -
The Effects of Maternal Obesity on the Innate Immune System: Developmental Programming of Kupffer Cells
(2023-03-29)The global epidemic of obesity has led to an increasing number of obese women in childbearing age. It is now understood that maternal obesity has harmful consequences on fetal and adult health. The underlying mechanism of ... -
Aneignung und Beheimatung von Grundschulkindern in Bonner Stadtquartieren
(2023-03-27)„Heimat“ verbinden viele Erwachsene mit dem Ort, an dem sie als Kind gelebt haben und aufgewachsen sind (IFD ALLENSBACH 2018, S. 12), und die Kindheit gilt als die Phase im Leben, in der räumliche und soziale Stabilität ... -
Temporal Knowledge Graph Embedding and Reasoning
(2023-03-27)Knowledge Graphs (KGs) have emerged as an efficient way to organize and represent knowledge by storing the underlying relations between entities. Recently, a large amount of research works have been devoted to KG embeddings, ... -
Density split statistic in cosmic shear surveys: Generalisations and its application to the Kilo Degree Survey
(2023-03-24)Understanding the formation and evolution of the Universe’s large-scale structure are fundamental in modern cosmology. Currently, the most accurate model to describe the LSS and other observations like the cosmic microwave ... -
Extracting Hadamard Coefficients from Green's Operators
(2023-03-20)We develop a formula for the diagonal values of the Hadamard coefficients associated to a normally hyperbolic operator on a globally hyperbolic spacetime in terms of the advanced and retarded Green's operators. We develop ... -
Modifikationen von Anwendungen, Konformationen und Selektivitäten von Titanocenen
(2023-03-16)Diese Arbeit beschäftigt sich mit drei verschiedenen Aspekten, die die Modifikation von Anwendungen, stereochemischen Aspekten und Selektivitätseigenschaften von Titanocenen behandeln. Im ersten Teil der ... -
The CAS protein and Ca2+ signaling in the chloroplast of Arabidopsis thaliana
(2023-03-16)There has been evidence that CAS forms a complex in the chloroplast of Chlamydomonas with PSI, CYTb6/f, and other proteins like PGRL1 and ANR1. However, in A. thaliana, such a CAS complex has not been shown yet. Therefore, ...
