Aging towards walkable futures : insights from a multidisciplinary workshop held in Barcelona, Spain

Background: The aging of the world’s population and the increase in sedentary lifestyles are leading to an increase in walking impairments at older ages. Here, we aimed to comprehensively discuss walking in the context of an aging population; and identify and agree on a list of future research priorities and policy actions. Methods: We followed a participatory approach and held a multidisciplinary

Nonlinear forecasting with many predictors using mixed data sampling kernel ridge regression models

Policy institutes such as central banks need accurate forecasts of key measures of economic activity to design stabilization policies that reduce the severity of economic fluctuations. Therefore, this paper develops a kernel ridge regression estimator in a mixed data sampling framework. Kernel ridge regression can handle many predictors with a nonlinear relationship to the target variable. Consequ

Exploring Authenticity in the Dialogical Self : A Conceptual Assemblage

In dialogical self theory (DST) authenticity has not been a central concern. The humanist notion of a static, higher-order, superordinate, ultimate, and “true” self runs counter to the ontology of DST, and the conceptualization of the dialogical self as unconsolidated, multifaceted, dynamic, and sensitive to situational change. In a climate in which the psychology of authenticity is undergoing rev

Coherence of an Electronic Two-Level System under Continuous Charge Sensing by a Quantum Dot Detector

We investigate experimentally the quantum coherence of an electronic two-level system in a double quantum dot under continuous charge detection. The charge state of the two-level system is monitored by a capacitively coupled single quantum dot detector that imposes a backaction effect on the system. The measured backaction is well described by an additional decoherence rate, approximately linearly

Noden i Varvsstaden - en strategi för att gestalta med tid

En stad är aldrig färdig, genom byggda förändringar och omförhandlade relationer. Samtidigt är en stad alltid färdig genom nuet hos dem som bor i den. Detta projekt syftar till att undersöka denna paradox och hur medvetenheten om tid och förändring kan berika design. Det studerade området för projektet är Varvsstaden i Malmö. En plats som en gång i tiden var en del av ett av världens största skeA city is always in the process of becoming, through built changes and renegotiated relationships. At the same time, a city is always finished through the present of those who live in it. This project aims to investigate this paradox and how the awareness of time and change can enrich design. The studied area of the project is Varvsstaden in Malmö. A place which was once a part of one of the lar

Seasonal carbon flux variations in temperate forests in southern Sweden

Forests play a crucial role in mitigating climate change by sequestering 29% of anthropogenic emissions. However, their sink capacity is highly sensitive to climate-induced disturbances, such as weather extremes, which can cause significant interannual variations in Net Ecosystem Exchange (NEE). With environmental stressors likely to become more frequent, understanding the drivers behind carbon ex

Ozonation-Induced Changes of Azathioprine and Flutamide : A Non-Targeted Analysis Using UHPLC-IM-HRMS and NMR

Cytostatika är läkemedel som används för att behandla cancer genom att hämma eller stoppa celldelning. De används även som immunhämmande medel, till exempel vid organtransplantationer och autoimmuna sjukdomar. Eftersom dessa läkemedel påverkar cellers tillväxt kan de vara skadliga även i mycket små mängder om de hamnar i miljön. Cytostatika har upptäckts i ytvatten, grundvatten och dricksvatten i Introduction: Cytostatic pharmaceuticals are increasingly detected in the aquatic environment, raising concerns due to their persistence and toxicity. Background: Conventional wastewater treatment processes do not effectively remove these compounds. Advanced oxidation processes, such as ozonation, are needed to degrade cytostatic pharmaceuticals during wastewater treatment. However, these process

Sara höll på och nös: Progressiv aspekt i svenskan

Syftet med denna uppsats har varit att undersöka om progressiva konstruktioner har blivit vanligare i svenskan. Bakgrunden till frågeställningen var en misstanke om att konstruktionen håller på och + V har blivit vanligare. Den första forskningsfrågan var: Har konstruktionen håller på och + V blivit vanligare på bekostnad av konstruktionen håller på att + V? Den andra forskningsfrågan var: Har kon

Spray-dried powders for inhalation

The pulmonary route has emerged as a promising strategy for delivering protein therapeutics, particularly for patients suffering from respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary infections. This project investigated the effect of operating parameters of a laboratory spray dryer on the characteristics of powders composed of Bovine Serum Albumin

Är systematisk skattebrottslighet lönsam? En analys av rättsliga och ekonomiska utmaningar vid lagföringen av skattebrott under två prisbasbelopp

Digitaliseringen erbjuder nya möjligheter för de kriminella, bland annat att resurseffektivt begå skattebrott med små belopp systematisk och på så vis undanhålla stora summor. Men vid lagföringen begränsas rättssystemet av lagstiftningens utformning och de ekonomiska resurserna. Detta skapar ett nytt problem, klyftan mellan resursen som krävs för att begå respektive lagföra brott blir ännu större.The process from crime to sentencing in case of tax fraud when the withheld sum is less than two price base amounts is a lengthy one. Firstly, the crime must be identified, and only one in ten income tax returns is reviewed by the Swedish Tax Agency. The crime must then be investigated, and the person who provided the incorrect information rarely cooperates during the investigation. The Swedish ta

Optimizing the Temperature Sensitivity of the Isoprene Emission Model MEGAN in Different Ecosystems Using a Metropolis-Hastings Markov Chain Monte Carlo Method

Isoprene is a reactive hydrocarbon emitted to the atmosphere in large quantities by terrestrial vegetation. Annual total isoprene emissions exceed 300 Tg a−1, but emission rates vary widely among plant species and are sensitive to meteorological and environmental conditions including temperature, sunlight, and soil moisture. Due to its high reactivity, isoprene has a large impact on air quality an
