Optimizing LUT-based inversion of leaf chlorophyll from hyperspectral lidar data : Role of cost functions and regulation strategies

Hyperspectral lidar (HSL) is a novel remote sensing technology that provides spectral information in addition to spatial features. This unprecedented data source leads to new possibilities for monitoring leaf biochemistry. Inversion of physically based radiative transfer models (RTMs) is a popular method for deriving leaf physiological traits due to its robustness and generalization capability. Ho

Secondary ice production during the break-up of freezing water drops on impact with ice particles

We provide the first dedicated laboratory study of collisions of supercooled water drops with ice particles as a secondary ice production mechanism. We experimentally investigated collisions of supercooled water drops (∼5 mm in diameter) with ice particles of a similar size (∼6 mm in diameter) placed on a glass slide at temperatures >-12 °C. Our results showed that secondary drops were generated d

Forest biodiversity and ecosystem services from spruce-birch mixtures : The potential importance of tree spatial arrangement

There is increasing empirical support for the biodiversity and ecosystem service (ES) benefits of mixed-species production forests. However, few studies control for the spatial arrangement of the trees within mixtures to determine the influence that clustering the tree species (patch scale mixtures), versus evenly dispersing them (intimate scale mixtures), may have for biodiversity and ES outcomes

Effects of red blood cell transfusions given to non-septic critically ill patients : a propensity score matched study

Background: Previous studies have demonstrated that low-grade red blood cell transfusions (RBC) given to septic patients are harmful. The objectives of the present study were to compare mortality and morbidity in non-septic critically ill patients who were given low-grade RBC transfusions at haemoglobin level > 70 g L–1 with patients without RBC-transfusions any of the first 5 days in intensive ca

The power of maps in shaping visions about the Arctic

Maps have the ability to make abstract information visible and real to their audiences. They provide humans a way to conceptualize and understand places and issues that otherwise might seem both distant and abstract. This article argues that maps influence what issues are visible and knowable and what issues are silenced and disregarded, often giving prominence to dominant understandings. As such,

Characterization on the impact of different clarifiers on the white wine colloids using Asymmetrical Flow Field-Flow Fractionation

Clarifiers are substances used during the winemaking process to enhance clarity and stability in the wines. The different clarifiers may alter removal capacities differently. In this study, the removal efficiency of seven common fining agents, divided into three groups (mineral clarifiers, synthetic polymeric clarifiers, and vegetable protein clarifiers), was analyzed with Asymmetrical Flow Field-

Inferring causal pathways between metabolic processes and liver fat accumulation: an IMI DIRECT study

Type 2 diabetes (T2D) and non-alcoholic fatty liver disease (NAFLD) often co-occur. Defining causal pathways underlying this relationship may help optimize the prevention and treatment of both diseases. Thus, we assessed the strength and magnitude of the putative causal pathways linking dysglycemia and fatty liver, using a combination of causal inference methods.Measures of glycemia, insulin dynam

Strategies for aggregating risk information in a societal safety context

Risk assessment is a useful tool in ensuring the continuous operation of critical societal functions. It can be used on many levels of an organization or society. One way to conduct risk assessments on higher system levels is to aggregate risk information from lower-level assessments. However, the process of aggregating risk information can be complex and different strategies for such aggregation Risk assessment is a useful tool to inform decision-making when it comes to ensuring the continuous operation of critical societal functions. It can be used on many levels within an organization or on multiple societal levels. One way to conduct risk assessments on a higher system level, such as on national level, is to aggregate risk information from lower-level assessments, e.g. from the regiona

Site Characteristics Mediate the Relationship Between Forest Productivity and Satellite Measured Solar Induced Fluorescence

Solar-Induced Chlorophyll Fluorescence (SIF) can provide key information about the state of photosynthesis and offers the prospect of defining remote sensing-based estimation of Gross Primary Production (GPP). There is strong theoretical support for the link between SIF and GPP and this relationship has been empirically demonstrated using ground-based, airborne, and satellite-based SIF observation

A risk perspective on common operational pictures : A case study of the Swedish Counties’ Coordination Office for the Covid-19 respons

The Covid-19 crisis has led to widespread impacts on society, not only in terms of high death tolls, but also in terms of cascading effects for essentially all societal sectors; especially due to all measures taken to reduce the spread of the disease. A range of actors have become involved in the response to the pandemic and to ensure appropriate actions being taken, these actors need good situatiThe Covid-19 crisis has led to widespread impacts on society, not only in terms of high death tolls, but also in terms of cascading effects for essentially all societal sectors; especially due to all measures taken to reduce the spread of the disease.

Nitrogen restricts future sub-Arctic treeline advance in an individual-based dynamic vegetation model

Arctic environmental change induces shifts in high-latitude plant community composition and stature with implications for Arctic carbon cycling and energy exchange. Two major components of change in high-latitude ecosystems are the advancement of trees into tundra and the increased abundance and size of shrubs. How future changes in key climatic and environmental drivers will affect distributions

A method for combined risk and continuity management in a municipal context

This paper presents a method for municipal Risk and Vulnerability Analysis which has been developed in an action research process together with a Swedish. The method combines aspects of both conti-nuity and risk management in order to exploit their strengths and avoid their limitations. It is developed to be applicable by municipal departments, i.e. a sub-part of the municipal organisations which

Readout of Quantum Screening Effects Using a Time-Dependent Probe

In voltage- and temperature-biased coherent conductors quantum screening effects occur if the conductor's transmission is energy dependent. Here, we show that an additional ac-driven terminal can act as a probe for a direct readout of such effects, hitherto unexplored. We find that screening of charges induced by the static biases impacts already their standard linear thermoelectric response coeff

More on the weak gravity conjecture via convexity of charged operators

The Weak Gravity Conjecture has recently been re-formulated in terms of a particle with non-negative self-binding energy. Because of the dual conformal field theory (CFT) formulation in the anti-de Sitter space, the conformal dimension ∆(Q) of the lowest-dimension operator with charge Q under some global U(1) symmetry must be a convex function of Q. This property has been conjectured to hold for a

The archaeological excavation carried out in 1988 by the University of Málaga’s Area of Prehistory in the surrounding area of the Viera dolmen identified significant evidence of settlement and funerary practices in Antiquity. In the framework of the Research Project “Societies, Territories and Landscapes in the Prehistory of the Lands of Antequera (Málaga)” (2013-2018) a systematic study of the ma

Practicing civic professionalism through inter-professional collaboration : Reconnecting quality with equality in the Nordic music school system

This chapter argues that encouraging teachers to strive towards civic professionalism is the key to equipping music schools with the tools to align with societal changes. All of the case descriptions highlight the practical use of inter-professional collaboration across sectors in problem-solving, this being one possible element in realising civic professionalism in practice. Social innovations ca

Kvalitet +rätt skötsel = en mångfald av urbana pollinatörer

TEMA: URBAN BIODIVERSITET Stadsmiljöns värde för pollinatörer beror av både utformningen av staden och kvaliteten på de gröna miljöerna. I bästa fall kan städer vara ett viktigt komplement till naturen runt om för den regionala mångfalden av bin, särskilt genom villaträdgårdarna. Vi har undersökt bin, blomflugor och fjärilar och hur de trivs i staden jämfört med i den omkringliggande landsbygden.
