A century of theories of balancing selection

Traits that affect organismal fitness are often very genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature (after all) “selects” the best genotypes at the expense of those that fall short. Explaining the extensive genetic variation of fitness-related traits is thus a longstanding puzzle in evolutionary biol

A Movable Combined Water Treatment Facility for Rainwater Harvesting

Alarming water shortage and increased water scarcity worldwide has led to increased interests in alternative water sources. Rainwater harvesting is one of them which is getting more and more attention. There is a huge potential for generalization and extension of rainwater harvesting system as an alternative water supply. This is especially important for arid and semi-arid regions where the water

Var tillverkades skånekannan?

This paper revisits the glazed redware Scanian jug, brought to the fore by Kulturen archaeologist Anders W. Mårtensson in 1973. Characterized by its faceted base and distinct handle, the jug stands out from its contemporaries. This brief paper presents new chemical data for the Scanian jug, its most common rim forms and a discussion on its area of production. So far, no medieval ceramic production

The evolution of extreme high and low temperatures in Sweden during 1882-2020

The ongoing climate change has been increasingly reflected in climate observations around the world, both in terms of averages and extremes, and attributed to anthropogenic climate forcing. When it comes to changing extremes, attribution to climate change is now especially well-established for heat-related extremes worldwide. Understanding changes in extremes is important for climate adaptation as

POLLENOMICS: Decoding the Farming History of Europe Using Advanced Statistics to Combine Ancient DNA with Paleo-Pollen Data

This study uniquely combines advanced continental-scale data from two distinct sources: pollen-based past land cover (paleoecology) and ancient DNA (aDNA), developing a novel statistical model for spatiotemporal reconstructions of past land use across Europe. This groundbreaking approach integrates paleo-pollen and aDNA data, providing unprecedented insights into the environmental impacts of Holoc

POLLENOMICS: Decoding the Farming History of Europe Using a Bayesian Approach Combining Compositional Data with a Point Process

This study uniquely combines advanced continental-scale data fromtwo distinct sources: pollen-based land cover (PbLC) and ancient DNA(aDNA), developing a novel statistical model for spatiotemporal reconstructionsof past land use across Europe.The aDNA data serves as a proxy for human habitation, differentiatinganthropogenic and natural land cover from PbLC reconstruction. Thiswill be accomplished

Decision Support System in Hydrological Modeling - A case study in China

Generally speaking, Computer based numerical hydrological models have been playing a very central role during the last decades in dealing with water resources related problems. Various kinds of conceptual, physical and stochastical models have been developed. Perhaps the most important contribution of those models is the ability of simplifying and schematizing a complex problem in the nature and s

Contribution of prioritized urban nature-based solutions allocation to carbon neutrality

Nature-based solutions (NBS) are essential for carbon-neutral cities, yet how to effectively allocate them remains a question. Carbon neutrality requires city-led climate action plans that incorporate both indirect and direct contributions of NBS. Here we assessed the carbon emissions mitigation potential of NBS in European cities, focusing particularly on commonly overlooked indirect pathways, fo

Disinfection and Fresh-Keeping of Rainwater in Small Scale Cisterns

Various disinfectants are examined in a study for disinfection and fresh-keeping of collected rainwater in cisterns in arid areas of China. Among the tested disinfectants (chlorine, ozone, chlorine dioxide, potassium permanganate, chloramines and hydrogen peroxide etc.), chlorine dioxide has proved to be the most feasible and effective oxidant for drinking water storage and disinfection of rainwat

Small-scale rainwater cistern system for rainwater collection in north-western China

Despite the overall rapid economical development during the last decade in China, a number of regions in remote areas are still striving to alleviate poverty. These regions are commonly characterized by low level of industrialization, poorly developed agriculture, which almost entirely relies on climate situations. Water has often been a bottle-neck in the development of the agricultural, industri

Spatial dynamic modelling for urban scenario planning: A case study of Nanjing, China

Although urban scenario planning is widely applied for exploring various directions of urban development, it often has high requirements on the medium of quantitative information analysis and transformation. Thus, this study establishes a method of combining scenario planning with a spatial dynamic planning support system to predict urban growth. Specifically, a scenario-based spatial dynamic mode

Urban spatial dynamic modeling based on urban amenity data to inform smart city planning

An ideal form of smart city planning would focus on the availability of urban amenities that can meet the basic needs of a resident’s material life, civil connections, and humanistic spirit. Previous studies have concentrated on analyzing the spatial distribution of urban services, with less attention on their contribution as local urban amenities. In this study, we propose a spatial dynamic model

Reconstruction of past human land use from pollen data and anthropogenic land cover changes

Accurate maps of past land cover and human land use are necessary for studying the impact of anthropogenic land-cover changes, such as deforestation, on the climate. The maps of past land cover should ideally be separated into naturally occurring vegetation and human-induced changes, thereby enabling the quantification of the effect of human land use on the past climate. A Bayesian hierarchical mo

Addressing the segmentation challenge posed by 3D pore patterns and thickness of foraminiferal tests

Over the past two centuries, coastal regions have experienced various anthropogenic environmental stressors such as ocean acidification, pollution, warming, and deoxygenation that have impacted benthic marine life. Understanding the severity and potential outcomes of such changes is crucial for supporting effective environmental management strategies.Benthic foraminifera, protists with calcite tes

Morphological variations of calcite microfossils synchrotron-based μCT reveal the last 200 years of environmental changes at the Baltic Sea entrance

Human activities in coastal areas have accelerated during the last 200 years. Environmental changes resulting in a combination of three threats, i.e., deoxygenation, warming, and ocean acidification, impact particularly sub-polar regions. To better understand these environmental challenges, we need to develop tools to compare our present situation with previous periods less impacted by anthropogen

Climate variability and anthropogenic impacts through a palaeo-morphological lens: an innovative microCT approach using Baltic Sea benthic foraminifera

Human-induced impacts are increasing pressure on coastal ecosystems, particularly on benthic ecosystems in high-latitude regions. It has become evident that three of the greatest marine environmental challenges related to anthropogenic activity are warming, ocean acidification, and deoxygenation. The effect of these environmental changes on our uncertain future has created a need to understand the

Time-series anonymization of tabular health data using generative adversarial network

Data anonymization has been used as a fundamental tool in various domains, e.g. healthcare, to alter personal data such that individuals can no longer be identified directly or indirectly in a way to enable broader sharing of data. For example, data perturbation techniques add noise to original data allowing individual record confidentiality while maintaining high-quality data for analytical purpo
