Observation of Significant Photosynthesis in Garden Cress and Cyanobacteria under Simulated Illumination from a K Dwarf Star
Iva Vilović, Dirk Schulze-Makuch, René Heller
Stars with about 45 to 80% the mass of the Sun, so-called K dwarf stars, have previously been proposed as optimal host stars in the search for habitable extrasolar worlds. These st…
Variations in climate habitability parameters and their effect on Earth's biosphere during the Phanerozoic Eon
Iva Vilović, Dirk Schulze-Makuch, René Heller
Essential insights on the characterization and quality of a detectable biosphere are gained by analyzing the effects of its environmental parameters. We compiled environmental and…
Mapping the brightness and color of urban to rural skyglow with all-sky photometry
Andreas Jechow, Christopher C. M. Kyba, Franz Hölker
Artificial skyglow is a form of light pollution with wide ranging implications on the environment. The extent, intensity and color of skyglow depends on the artificial light source…
Habitability Models for Astrobiology
Abel Méndez, Edgard E. Rivera-Valentín, Dirk Schulze-Makuch +31
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
Evolution of default genetic control mechanisms
William Bains, Enrico Borriello, Dirk Schulze-Makuch
We present a model of the evolution of control systems in a genome under environmental constraints. The model conceptually follows the Jacob and Monod model of gene control. Genes…
Recovering the city street lighting fraction from skyglow measurements in a large-scale municipal dimming experiment
John C. Barentine, František Kundracik, Miroslav Kocifaj +7
Anthropogenic skyglow dominates views of the natural night sky in most urban settings, and the associated emission of artificial light at night (ALAN) into the environment of citie…
The nature of the diffuse light near cities detected in nighttime satellite imagery
Alejandro Sánchez de Miguel, Christopher C. M. Kyba, Jaime Zamorano +2
Diffuse glow has been observed around brightly lit cities in nighttime satellite imagery since at least the first publication of large scale maps in the late 1990s. In the literatu…
The role of artificial intelligence in achieving the Sustainable Development Goals
Ricardo Vinuesa, Hossein Azizpour, Iolanda Leite +7
The emergence of artificial intelligence (AI) and its progressively wider impact on many sectors across the society requires an assessment of its effect on sustainable development.…
Effects of publication bias on conservation planning
Raffael Hickisch, Timothy Hodgetts, Paul J. Johnson +3
Conservation planning needs reliable information on spatial patterns of biodiversity. However, existing data sets are skewed: some habitats, taxa, and locations are under-represent…
Tracking the dynamics of skyglow with differential photometry using a digital camera with fisheye lens
Andreas Jechow, Salvador J. Ribas, Ramon Canal-Domingo +3
Artificial skyglow is dynamic due to changing atmospheric conditions and the switching on and off of artificial lights throughout the night. Street lights as well as the ornamental…
Using all-sky differential photometry to investigate how nocturnal clouds darken the night sky in rural areas
Andreas Jechow, Franz Hölker, Christopher C. M. Kyba
Artificial light at night has affected most of the natural nocturnal landscapes worldwide and the subsequent light pollution has diverse effects on flora, fauna and human well-bein…
BioTracker: An Open-Source Computer Vision Framework for Visual Animal Tracking
Hauke Jürgen Mönck, Andreas Jörg, Tobias von Falkenhausen +7
The study of animal behavior increasingly relies on (semi-) automatic methods for the extraction of relevant behavioral features from video or picture data. To date, several specia…
Early warning signal for interior crises in excitable systems
Rajat Karnatak, Holger Kantz, Stephan Bialonski
The ability to reliably predict critical transitions in dynamical systems is a long-standing goal of diverse scientific communities. Previous work focused on early warning signals…
Measuring night sky brightness: methods and challenges
Andreas Hänel, Thomas Posch, Salvador J. Ribas +10
Measuring the brightness of the night sky has become an increasingly important topic in recent years, as artificial lights and their scattering by the Earths atmosphere continue sp…
Second-order coherence properties of amplified spontaneous emission from a high-power tapered superluminescent diode
Jan Kiethe, Axel Heuer, Andreas Jechow
We study the degree of second-order coherence of the emission of a high-power multi-quantum well superluminescent diode with a lateral tapered amplifier section with and without fe…
Imaging and mapping the impact of clouds on skyglow with all-sky photometry
Andreas Jechow, Zoltán Kolláth, Salvador J. Ribas +3
Artificial skyglow is constantly growing on a global scale, with potential ecological consequences ranging up to affecting biodiversity. To understand these consequences, worldwide…
Frequency doubling of temporally incoherent light from a superluminescent diode in a periodically poled lithium niobate waveguide crystal
Henning Kurzke, Jan Kiethe, Axel Heuer +1
The amplified spontaneous emission from a superluminescent diode was frequency doubled in a periodically poled lithium niobate waveguide crystal. The temporally incoherent radiatio…
The new world atlas of artificial night sky brightness
Fabio Falchi, Pierantonio Cinzano, Dan Duriscoe +6
Artificial lights raise night sky luminance, creating the most visible effect of light pollution-artificial skyglow. Despite the increasing interest among scientists in fields such…
Proto-Cooperation: group hunting sailfish improve hunting success by alternating attacks on grouping prey
James E Herbert-Read, Pawel Romanczuk, Stefan Krause +8
We present evidence of a novel form of group hunting. Individual sailfish (Istiophorus platypterus) alternate attacks with other group members on their schooling prey (Sardinella a…
Evaluating the summer night sky brightness at a research field site on Lake Stechlin in northeastern Germany
Andreas Jechow, Franz Hölker, Zoltán Kolláth +2
We report on luminance measurements of the summer night sky at a field site on a freshwater lake in northeastern Germany (Lake Stechlin) to evaluate the amount of artificial skyglo…
Fast Computation on Semirings Isomorphic to on
Oliver Serang
Important problems across multiple disciplines involve computations on the semiring (or its equivalents, the negated version ), the log-transformed…
A Bounded -norm Approximation of Max-Convolution for Sub-Quadratic Bayesian Inference on Additive Factors
Julianus Pfeuffer, Oliver Serang
Max-convolution is an important problem closely resembling standard convolution; as such, max-convolution occurs frequently across many fields. Here we extend the method with faste…
A fast numerical method for max-convolution and the application to efficient max-product inference in Bayesian networks
Oliver Serang
Observations depending on sums of random variables are common throughout many fields; however, no efficient solution is currently known for performing max-product inference on thes…
