Controlling Data Streams of IoT Devices in Smart Homes from a User Perspective
(2024-04-16)Increasingly, humans are surrounded by intelligent devices, such as smart devices, in the Internet of Things (IoT) context. These smart devices are used in various environments, such as smart environments as well as homes. ... -
Development of experimental and numerical models to predict the behavior of Kinetic Interface Sensitive (KIS) tracers for multiphase flow in porous media systems - A novel reactive tracer to measure fluid-fluid interfacial area in both static and dynamic conditions
(2024-04-12)An important aspect of understanding the behavior of a two-phase flow system is detecting and measuring the Fluid-Fluid Interfacial Area (FIFA). For example, in underground Gas/Oil/CO2 storage where two phases can co-exist, ... -
Femtosecond spectroscopy of charge-transfer dynamics in self-assembled Pd(II) based donor-acceptor/host-guest cages and heterobinuclear alkyne-bridged W(II)-Ru(II) and W(II)-Ir(III) complexes
(2024-04-11)Using femtosecond UV/vis-pump-UV/vis-probe and -midIR-probe absorption spectroscopy the charge-transfer dynamics of self-assembling donor-acceptor Pd(II) coordination cages and heterobinuclear alkyne-bridged W(II)-Ru(II) ... -
Theoretical studies of metal-metal cooperativity in pyrazolate-bridged complexes
(2024-04-11)Transition metal complexes can play a variety of important roles in regard to catalysis, materials synthesis, photochemistry, and biological systems through use of their unique electronic structure, and the resulting ... -
Generalizations of Quandles to Multi-Linkoids
(2024-04-10)In this thesis, we define the fundamental quandle of knotoids and linkoids and prove that it is invariant under the under forbidden-move and hence encodes only the information of the underclosure of the knotoid. We ... -
Fundamental data and conceptual framework for the exploration of geothermal resources in the Himalaya-Karakoram Orogenic belt, northern Pakistan
(2024-04-08)Northern Pakistan lies within the collision zone of the Indian and Asian plates comprising Himalaya, Kohistan, and Karakoram, with numerous hot springs associated with the Himalayan Geothermal Belt, extending 3000 km along ... -
Effects of managed forest stand composition on small mammal demography and reciprocal effects on seed predation patterns in Northern Germany
(2024-04-08)In an effort to ameliorate the impacts of climate change, forest managers in Central Europe increasingly turn to conifer species that produce higher yields and are better adapted to projected future climatic conditions. ... -
Evaluating a Collection of Agronomic Traits to Better Understand the Importance of Epistasis and Epistasis by Environment Interaction in Maize.
(2024-04-05)Maize, a key cereal crop, stands alongside wheat and rice in global importance. Its domestication from teosinte in southern Mexico 10,000 years ago marked a turning point in human agriculture. Over the centuries, maize has ... -
Auswirkung von Bodenbearbeitungen auf den Nährstoffhaushalt von Waldböden sowie den Erfolg von Eichenkulturen
(2024-04-05)Site preparation in forests has received criticism for potentially reducing site produc-tivity due to soil compaction and nutrient losses. Nontheless, from a practical perspec-tive, site preparation is an essential factor ... -
Vergleich von stillgelegten und bewirtschafteten Wäldern anhand von zwei Fallbeispielen in Brandenburg
(2024-04-02)Forests can provide a wide range of ecosystem services. However, not all ecosystem services can be maximized at the same time, which can lead to conflicting objectives. For example, objectives range from maximizing the ... -
Exploiting the Disulfide/Thiol Switch for Photoinduced Proton-Coupled Multielectron Transfer Reactivity
(2024-03-27)Energy storage and efficient release has become a pivotal issue for our society relying progressively on renewable energy sources. The dichotomy between harvesting the sun’s energy in daylight hours, and requiring it the ... -
Changes in Microbial Resources and Trophic Niches of Microarthropods in Forest Ecosystems with Elevation
(2024-03-27)Mountain forests play a major role for biodiversity conservation, carbon storage and hydrological cycling. Therefore, understanding different components of mountain forest ecosystems is essential to predict potential ... -
Holocene vegetation and environmental changes with a focus on peat ecosystems in southwestern and northeastern Amazonia
(2024-03-27)Amazon rainforests are well-known for playing a significant role in the climate, hydrological cycle, and biodiversity on earth. Recent investigations found that Amazonia may contain the largest peat carbon (C) stock in the ... -
Characterization of testosterone and androgen receptor action in human and rhesus macaque heart muscle cells
(2024-03-26)Androgens are sex steroid hormones that influence various processes in reproductive tissues and peripheral organs. Their lipophilic nature enables free diffusion through the plasma membrane. In the cytoplasm, testosterone ... -
A novel rRNA quality control function for Npl3 in Saccharomyces cerevisiae
(2024-03-25)In all domains of life, ribosomes are essential complexes that are the sole source for protein synthesis. Ribosome biosynthesis, the most energy-consuming process in a cell, has to be tightly regulated. Misregulation ... -
