Climate warming has significantly advanced plant spring phenology in temperate and boreal biomes in the northern hemisphere. However, the response of subtropical forest phenology to climate change remains largely unclear. This study aimed to determine the spatiotemporal patterns of spring photosynthetic phenology in subtropical forests in China over the period 2002-2017 and explore its underlying

Submerged aquatic vegetation (SAV) is one of the main producers in inland lakes. Tracking the temporal and spatial changes in SAV is crucial for the identification of state changes in lacustrine ecosystems, such as changes in light, nutrients, and temperature. However, the available SAV classification algorithms based on remote sensing are highly dependent on field survey data and/or human interve

This thesis is devoted to the understanding, application, and extension of coherent lensless imaging methods for microscopy purposes. Particular attention is given to the Fourier transform holography and coherent diffractive imaging methods.These two methods share several properties such as the ability for singleshot imaging and their experimental geometries, but differ greatly in their reconstruc

In recent years, the traditional gender gap in educational attainment in favor of men has been reversed in many countries. This development may have far-reaching consequences for the family, challenging traditional patterns of union formation and potentially affecting marriage and fertility outcomes. I study the implications of the female advantage in education on family formation through changes

Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued signal from measurements of its amplitude. We describe a generalization of this method for multi-wavelength data acquired in a coherent diffractive imaging experiment. It exploits the wavelength-dependent scaling of the support domain to recover separate reconstructions for each wavelength, providing new possi

Poly(butylene adipate-co-terephthalate) (PBAT) is an important commercial biodegradable flexible copolyester, which is dependent on the fossil-based terephthalates for production. In the present work, two series of PBAT-mimicking copolyesters are synthesized using lignin-sourced aromatic monomers, i.e., methyl 4-(2-hydroxyethoxy) vanillate and methyl 4-(2-hydroxyethoxy) benzoate, aliphatic dimethy

Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. Although previous studies provide insight into the cognitive underpinnings of semantic representations, they have suffered from small sample sizes and a lack of linguistic and cultural diversity. In this Registered Report, we measured the size and the variability of the seman

Over the past fifteen years, Rwanda has made significant progress in formalizing mining rights and the production processes of 3Ts minerals in its artisanal and small-scale mining (ASM) sector. However, labour relations remain largely unregulated. This study analyses ASM activities through the production process observations, document reviews, and interviews with key informants involved in the sec

Darknet constitutes a part of the internet with a reputation for allowing deviance and criminality. In short, it is often understood as a place where anything goes. Current research on Darknet tends to focus on illicit cryptomarkets, however in this ongoing doctoral research project, I explore how user posts and behaviors are informally and formally controlled and shaped on Darknet forums. Moreove

Global clothing consumption is increasing, with many garments having unnecessarily short lifetimes due to low quality materials and manufacturing, often linked to price pressures. Current European Union strategies focus on improving technical durability, product maintenance, and waste collection, but fail to address the role of the consumer for durable garments. A better understanding of drivers a

Regular, vigorous physical activity can have a significant impact on cardiac function, leading to cardiac morphological alterations that may be challenging to distinguish from pathological changes. Therefore, new screening methods are needed to accurately differentiate between adaptive changes and pathological alterations in athletes. Vortex formation time (VFT) is an emerging method that shows po

Objectives: The aim of the present study was to assess if vortex formation time (VFT) as a measurement of left ventricular (LV) diastolic function is affected by food intake and related to age and sex. Methods: Healthy participants were divided into two age groups: younger (median age: 25 years) and older (median age: 68 years). Transthoracic echocardiography (TTE) examinations were performed duri

Mot bakgrund av tilltagande ekologiska kriser, växande socioekonomiska ojämlikheter och ett klimat i förändring har behovet av att omvandla jordbrukssystem mot hållbarhet och rättvisa blivit alltmer akut. En sådan omvandling hindras emellertid ofta av djuprotade strukturer och institutionella arrangemang som gynnar snävt definierade föreställningar om produktivitet och marknadseffektivitet. DärigeAmid escalating ecological crises, widening socio-economic inequalities, and intensifying climate change, the imperative to transform agricultural systems towards sustainability and equity has become increasingly urgent. Yet suchtransformation is often hindered by entrenched institutional and structural arrangements that privilege narrowly defined notions of productivity and market efficiency, the
