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

The atomic structure of catalytic surfaces and its relation to function is important for the understanding and development of industrial catalysts. However, many surface sensitive methods are limited to low-pressure environments, creating a gap between experimental results and reality, and it is not certain that the findings can be applied to the real system. Surface X-ray diffraction is a method

INTRODUCTION: A recent study on patients with acute lower limb ischemia showed that the proportion of inadequate examination of lower extremity circulation was associated with higher rate of amputation and death. The aim of this systematic review was to explore evidence for how practical competence in performing a peripheral vascular status of the lower limb among medical students and junior docto

Non-typeable Haemophilus influenzae (NTHi) is an emerging respiratory pathogen that causes a significant disease burden worldwide, yet an effective vaccine is still lacking. The focus of this thesis is to elucidate the critical molecular interactions governing NTHi pathogenesis and host immunity. We identified Elongation Factor Tu (EF-Tu) as a surface-exposed protein on NTHi, demonstrating its imm

High latitude mires are key ecosystems in the context of climate change since they store large amounts of carbon while constituting an important natural source of methane (CH4). However, while a growing number of studies have investigated methane fluxes (FCH4) at the plot- (~1 m2) and ecosystem-scale (~0.1–0.5 km2) across the boreal biome, variations of FCH4 magnitudes and drivers at the mesoscale

Tropical forests provide essential ecosystem services, playing a critical role in climate regulation, biodiversity conservation, and regional hydrological cycles while also supporting livelihoods. However, they are increasingly threatened by deforestation and land-use change. Accurate land cover (LC) mapping is vital to monitor these changes, but mapping tropical forests is challenging due to comp

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

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

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.

Reliable maritime communication systems are essential for both safety-critical operations and emerging applications such as autonomous shipping, remote pilotage, and drone-assisted search and rescue. These scenarios demand ultra-reliable, low-latency wireless connectivity, where communication outages are unacceptable. Equally important is the need for dependable positioning systems. In situations

Alzheimer’s disease, the most common form of dementia, is characterized by progressive cognitive decline and the accumulation of amyloid-beta (Aβ) and tau neurofibrillary tangle (NFT) pathology. The medial temporal lobe (MTL) is one of the earliest sites of NFT pathology, crucial for memory functioning, and is made up of cytoarchitectonic and functionally different subregions. These subregions are

In a potato starch factory, potato proteins can also be obtained alongside the main product starch. After the denatured proteins have been withdrawn, the remaining potato fruit juice (PFJ) can be further concentrated through evaporation and used as a fertilizer. However, evaporators are highly energy-intensive. Instead, membrane filtration presents a more energy-efficient alternative for this proc

Introduction: Epidemiological studies on elite female ice hockey players are lacking but needed to tailor preventive efforts in this growing group of athletes. Therefore, the aim of this study was to describe the incidence, prevalence, and burden of health problems in elite female ice hockey players. Methods: In this prospective cohort study, we asked all Swedish Women's Hockey League (SWHL) playe
