In an era of climate change, as the intensity and frequency of droughts are expected to increase, effectiveclimate adaptation strategies become increasingly important for both natural ecosystems and society.Understanding vegetation's responses to drought and monitoring the impacts of drought on terrestrialecosystems are essential for developing reliable decision-support systems. This thesis aimed

The transition from unicellular to multicellular life remains one of evolution’s biggest mysteries. In this study we introduce symbioses with bacteria as a possible player. We use metagenomic analysis to investigate bacterial communities associated with Volvocine green algae, a model system for multicellularity. We compared bacterial communities of 34 algal species (21 unicellular and 13 multicell

Can Your Genes and Lifestyle Together Shape Your Risk of Parkinson’s Disease? Parkinson’s disease (PD) is one of the most common neurodegenerative disorders worldwide, yet its causes remain only partly understood. While some people inherit rare genetic mutations that directly cause PD, for most individuals, the risk is likely influenced by a complex mix of many common genetic variants and environ

This thesis discusses novel results in the area of code-based cryptography, ranging from cryptanalyses on several code-based cryptographic constructions to proposing a code-based authentication scheme based on a novel Syndrome Decoding variant.To address the looming threat of large-scale quantum computers that wouldbreak many widely-used public-key cryptosystems, the National Institute of Stan-dar

Blir du en fest för nästa objudna gäst? Under det varma halvåret är det många av oss som ser fram emot att kunna koppla av i skogen eller trädgården. Detta är något som vi i en snar framtid kan behöva göra med extra försiktighet. Till följd av olika faktorer, förväntas många svenskar bli utsatta för ett ökat antal fästingspridda sjukdomar. En av dessa sjukdomar orsakas av en malarialiknande parasDue to climate changes, a large human population, changed lifestyles and travel possibilities, many vector-borne diseases are now on the uprise. The tick-transmitted parasite, Babesia divergens spread by Ixodes ricinus ticks, is one of the emerging pathogens with possible serious outcomes. Most infected people do not obtain any symptoms, but individuals with a compromised immune system or elderly

Targeting TB: Scope of Anti-Mycobacterial Compounds Tuberculosis (TB) continues to be one of the leading cause of death until today. The disease has persisted since antiquity and remains a concern despite the advancement in its treatment. The main problem arises from antibiotic resistance developed by Mycobacterium tuberculosis and the complex nature of the bacteria which has developed mechanisms

Fiberbanks have recently received attention as potential greenhouse gas (GHG) sources in Sweden. Fiberbanks are anthropogenically caused fibre-rich sediments in aquatic environments formed by unregulated discharge of fibrous wastewater from historical pulp and paper industries. A majority of fiberbanks show signs of gas ebullition, mainly consisting of methane and carbon dioxide, resulting from an

Hur kan antibiotikabehandling vid tuberkulos bidra till lungskada? Varför drabbas många tuberkulospatienter av långvariga lungskador, trots att infektionen är botad? Ny forskning visar att antibiotikan i sig kan spela en oväntad roll. När bakterierna utsätts för stressen som antibiotikan orsakar, börjar de släppa ifrån sig små kapslar, liknande mikroskopiska paket, som kan trigga immunförsvaret oTuberculosis (TB) affects millions of people annually and remains one of the leading causes of infectious diseases-related deaths in the world. Current anti-TB treatment consists of a prolonged regimen of multiple antibiotics, which effectively eliminates the bacteria when it is not antibiotic resistant. However, large proportions of the TB-treated individuals experience persistent pulmonary dysfu

Orala streptokocker – munhålans gynnare och eventuella fiende Streptokocker är associerade med flera infektionssjukdomar i olika delar av kroppen. En grupp streptokocker (orala streptokocker) återfinns främst i människans munhåla i både friska och sjuka individer. Tidigare studier har visat att orala streptokocker etableras i munhålan redan när vi är barn och finns kvar under hela livet. I den frOral streptococci colonize the oral cavity already during early childhood and establish the foundation for colonization by a multispecies oral microbiota. In the oral cavity, Streptococcus spp. contribute to both health and disease, and can also spread to the blood stream causing bacteremia and systemic diseases such as infectious endocarditis (IE) in certain risk groups. Molecular changes in oral

BACKGROUND: Aortic pulse wave velocity (PWV) is an indicator of vascular aging and has proven to be effective in adult cardiovascular risk assessment. To use it in young people to identify those who may be at increased cardiovascular disease risk, reference values need to be determined. The Youth Vascular Consortium is a large, international database which was established to investigate vascular a

Since the conceptualization of early vascular aging (EVA) in 2008, significant efforts have been made to develop and improve its assessment. Initially lead by the investigation of arterial stiffness through pulse wave velocity (PWV), several additional vascular aging biomarkers have gained prominence in recent years. Despite expanding literature addressing methodological concerns associated with t

With an ongoing housing shortage in Swedish cities, challenges such as limited land availability, financing, and the environmental impacts associated with new development prompt us to explore alternative solutions. As architecture is inevitably a form of aesthetics and the idea of transforming and re-adapting our existing structures to deal with these challenges gains traction in the architectur

In the background of intensifying global climate change and rapid urbanisation, the frequent occurrence of extreme hydrological events and the increase in surface pollution pose serious challenges to the environmental quality of water bodies. Moreover, with the significant increase in public awareness of environmental protection, higher demands have been placed on water quality monitoring techniqu

International collaboration has long been regarded as a beneficial endeavour in higher education, fostering shared scientific and educational advancements, as well as cultural understanding. However, in developed economies, such academic partnerships have increasingly become entangled with geopolitical dynamics, competitive interests and national security issues.

The ability to generate and control movement is essential for human interactions and overall well-being. Neuromuscular impairment caused by neurological injuries and diseases, such as stroke or limb amputation, severely limits the ability of affected individuals to interact with the surrounding environment, necessitating advanced strategies for rehabilitation and restoration of motor function. Vol

This work addresses the design of multi-agent coordination through high-order consensus protocols. While first-order consensus strategies are well-studied—with known robustness to uncertainties such as time delays, time-varying weights, and nonlinearities like saturations—the theoretical guarantees for high-order consensus are comparatively limited. We propose a compositional control framework tha

To carry out the search mission, an additional narrow-angle video camera is installed on board the unmanned aerial vehicle (UAV). This video camera can be re-aimed at objects detected in the image frame received from the main (navigation) video camera. The movement of the additional video camera is carried out by two coordinated electric drives using direct current motors or brushless direct curre

The study is devoted to the development of the 2DCAM hardware and software complex for the physical modeling of the two-coordinate positioning system of the additional video camera of the UAV using the Simulink environment. DYNAMIXEL actuator systems were used to create a complex prototype. They combine DC motor, reduction gearhead, controller, driver and network components.The AH-12A actuator is

In collaboration with Spanish and Portuguese musicians, the group has recorded a new album that was released in April 2023. With roots in Nordic folk music, Groupa plays music that reflects both a deep, long-standing connection to tradition and a strong, unyielding desire to constantly move forward. After an intense celebration of Groupa’s 40th anniversary in 2021, the group continues its work of
