Temperature and Tree Size Explain the Mean Time to Fall of Dead Standing Trees across Large Scales

AbstractDead standing trees (DSTs) generally decompose slower than wood in contact with the forest floor. In many regions, DSTs are being created at an increasing rate due to accelerating tree mortality caused by climate change. Therefore, factors determining DST fall are crucial for predicting dead wood turnover time but remain poorly constrained. Here, we conduct a re-analysis of published DST f

Classification of point-of-care ultrasound in breast imaging using deep learning

Early detection of breast cancer is important to reduce morbidity and mortality. Access to breast imaging is limited in low- and middle-income countries compared to high-income countries. This contributes to advance-stage breast cancer presentation with poor survival. Pocket-sized portable ultrasound device, also known as point-of-care ultrasound (POCUS), aided by decision support using deep learn

Effect of magnetic order on longitudinal Tomonaga-Luttinger liquid spin dynamics in weakly coupled spin-1/2 chains

The quantum many-body interactions in one-dimensional spin- 1/2 systems are subject to Tomonaga-Luttinger liquid (TLL) physics, which predict an array of multiparticle excitations that form continua in momentum-energy space. Here we use inelastic neutron spectroscopy to study the TLL spin dynamics in SrCo2V2O8 , a compound which contains weakly coupled spin-1/2 chains of Co atoms, at 0.05 K and in

Windstorm impacts on European forest-related systems: an interdisciplinary perspective

Windstorms are considered the main disturbing abiotic agent in European forests. They affect a multiplicity of forest-related dimensions, such as forest ecology, forest operations, geomorphology, economy, and socio-cultural aspects. Due to the complex dynamics set off by windstorms, the design of post-windstorm forest management should be characterized by an interdisciplinary approach able to addr

Machine Learning

Machine learning, a sub-field of artificial intelligence, is the study of computer algorithms that improve automatically through experience. Although the term was coined in 1959, machine learning builds on questions/methods that were developed earlier in linear algebra, mathematical analysis, optimization, and mathematical statistics. In this chapter we will give a brief overview of machine learni

Analysis of policy frameworks for ‘children in care’ in Sweden

In a joint South African and Swedish research study, policy frameworks for children in care were analysed in regard to children’s rights and accessibility to participate in decisions on care. The research group has during phase one in the study developed a series of questions to analyse the most relevant legislations in regard to children in care. Thus, for the Swedish part of the analysis four le

A tale of two mechanisms : comparing mesostructure formation in cationic and non-ionic surfactant-templated silicas

The formation of surfactant templated silica films at the air-solution interface has been investigated in situ using a number of time-resolved surface-sensitive and bulk sensitive techniques. Results from templating solutions prepared using a non-ionic surfactant (C16EO8) are compared to those obtained when a cationic surfactant (CTAB) is used. In both cases specific solution phase interactions dr

Accessibility of dye molecules embedded in surfactant-silica hybrid materials in both powder and film forms

Two CTABr-silica mesophases have been prepared, one of them as a powder with hexagonal structure containing Congo Red, the other one as a film with cubic structure containing Disperse Red 1. In the former case the dye has been occluded via co-entrapping, whereas in the latter it has been covalently anchored to the silica matrix via a co-condensation route. In both systems, the dye molecules proved

Kvalitet på övergångsställen i olika socioekonomiska områden – finns det några samband?

Denna uppsats syftar till att bedöma kvaliteten på övergångsställen i olika stadsdelar av Helsingborg, baserat på riktlinjerna och föreskrifterna i VGU, HIN och ALM. Fem stadsdelar i Helsingborg - Råå, Planteringen, Söder, Centrum och Tågaborg - valdes ut för att representera en bred socioekonomisk och kulturell bakgrund. Målet var att identifiera eventuella skillnader i kvaliteten mellan stadsdelThis thesis aims to assess the quality of pedestrian crossings in different districts of Helsingborg, based on the guidelines and regulations in VGU, HIN, and ALM. Five districts in Helsingborg - Råå, Planteringen, Söder, Centrum, and Tågaborg - were selected to represent a wide socio-economic and cultural background. The goal was to identify any differences in the quality of the pedestrian crossi

Theorising affordability in co-housing: unravelling the how and when of its affordability potential

Affordability is often cited as a beneficial aspect of co-housing; however, the specific factors that contribute to its affordability and the theoretical understanding of this phenomenon have received limited attention in research. Against the backdrop of the ongoing affordable housing crisis, this study seeks to investigate the circumstances under which co-housing holds the potential for affordab

Market life and the city (of Vienna) - The social infrastructure of attachment to place

In this thesis, the relationship between people and places is investigated through examining how migrants in Vienna create place attachment to food markets in the city. A place attachment is understood as the emotional bond that forms between an individual and a specific space, the theoretical foundation of this thesis lies within emotional geography, a sub-field of human geography which examines

A preliminary choroid plexus volumetric study in individuals with psychosis

The choroid plexus (ChP) is part of the blood-cerebrospinal fluid barrier, regulating brain homeostasis and the brain's response to peripheral events. Its upregulation and enlargement are considered essential in psychosis. However, the timing of the ChP enlargement has not been established. This study introduces a novel magnetic resonance imaging-based segmentation method to examine ChP volumes in

Understanding the spatial non-stationarity in the relationships between malaria incidence and environmental risk factors using Geographically Weighted Random Forest : A case study in Rwanda

As found in the health studies literature, the levels of climate association between epidemiological diseases have been found to vary across regions. Therefore, it seems reasonable to allow for the possibility that relationships might vary spatially within regions. We implemented the geographically weighted random forest (GWRF) machine learning method to analyze ecological disease patterns caused

Comparison of psychedelic therapies versus placebo in the treatment of psychiatric illnesses: a systematic review of randomized trials including placebo controls

Psykedelika har länge erkänts för sina kraftfulla effekter på det mänskliga psyket och psykedelisk-assisterad terapi blir alltmer erkänd som en effektiv terapeutisk intervention. Placebo används i klinisk forskning för att validera effekten av en terapi eller behandling. Forskare är intresserade av att visa att en viss behandling är överlägsen jämfört med placebo. En utvärdering av den metodologisPsychedelics have long been recognized for their powerful effects on the human psyche and psychedelic-assisted therapy is becoming increasingly acknowledged as an effective therapeutic intervention. Placebos are used in clinical research to validate the efficacy of a therapy or treatment. Researchers are interested in showing that a certain treatment is superior compared to the placebo. An evaluat

Om-oss, digital storytelling för B2B företag

Användning av digital storytelling och multimodala tekniker skiljer sig markant för B2C och B2B företag. Effekten av digital storytelling för företags trovärdighet och företagsidentitet i B2B-sammanhang och särskilt för företagens “om-oss” sidor är sedan tidigare relativt outfors-kad. Studien underbyggs av fyra intervjuer med personer från fyra olika branscher och olika anställningsnivå. ResultateThe use of digital storytelling and multimodal techniques significantly differs between B2C and B2B companies. The effect of digital storytelling on corporate credibility and corporate identity in B2B contexts, and particularly for companies' "about us" pages, is relatively under-researched. The study is supported by four interviews with individuals from four different industries and

To dig or not to dig? An integrated post-structuralist analysis of the EU Critical Raw Materials Act and its justice implications for local communities

In its proposed 2023 Critical Raw Materials Act, the European Commission considers access to critical raw materials within its territory as key to both the green transition and to reduce import dependencies. This onshoring of extractivist practices warrants a critical analysis that reflects on the justice implications this may have for local communities. Therefore, I apply an integrated post-struc

Formation of mesostructured thin films at the air/water interface

Mesostructured thin films are known to form at the interface between either air or a solid surface and a dilute acidic solution containing the silica precursor, and surfactant template. These films are transparent, and, when grown at the air/solution interface, self-supporting. We have been studying the formation processes of these films to try to understand and thus control the formation of both

Study of the effects of the operating conditions of a decanter centrifuge on a pilot-scale protein recovery setup from cold-pressed rapeseed press cake

There is significant evidence to suggest that diets that include high levels of meat consumption have negative effects on both the environment and human health. As a result, efforts are being made to identify and characterize more plant-based proteins, such as those found in rapeseed. Rapeseed is the second-largest oilseed crop worldwide and is primarily used to produce edible oils through mechani
