Design and Evaluation of a Novel Low-Power Rectifier for RSSI in IEEE 802.11ax Wi-Fi Receivers

Received Signal Strength Indicator (RSSI) circuits are critical in modern Wi-Fi receivers, playing a key role in power management and protecting the radio frequency (RF) front-end from saturation and potential damage. This thesis presents the design and evaluation of a novel rectifier circuit conceptualized for use in an RSSI system within an industry-standard 22nm CMOS node, specifically targetin

Amphetamine use as a predictor of cardiovascular and cerebrovascular mortality and morbidity : a longitudinal cohort study of criminal justice clients

Introduction: Amphetamine use is an increasing problem, and studies suggest a connection between amphetamine use and cardiovascular and cerebrovascular pathology. However, few long-term studies examine amphetamine users' risk of cardiovascular and cerebrovascular pathology, in comparison to users of other drugs. In addition, in a criminal justice system, illicit drug use and psychiatric comorbidit

Cardiac arrest survivors’ self-reported cognitive function, and its association with self-reported health status, psychological distress, and life satisfaction—a Swedish nationwide registry study

Aim: Self-reported cognitive function has been described as an important complement to performance-based measurements but has seldom been investigated in cardiac arrest (CA) survivors. Therefore, the aim was to describe self-reported cognitive function and its association with health status, psychological distress, and life satisfaction.Methods: This study utilised data from the Swedish Register oAim: Self-reported cognitive function has been described as an important complement to performance-based measurements but has seldom been investigated in cardiac arrest (CA) survivors.

Self-reported executive functioning in adults with congenital cytomegalovirus infection

BACKGROUND: Congenital Cytomegalovirus (cCMV) is the most common prenatal infection and the main infectious cause of neurodevelopmental abnormalities in developed countries. Long-term neuropsychological outcome of cCMV infection is yet not well understood, and follow-up studies on adults screened for CMV at birth are few. The aim of this study was to investigate self-reported executive functioning

Fine-tuning the architecture of microgels by varying the initiator addition time

Poly-N-isopropylacrylamide (PNIPAM) microgels are versatile colloidal-scale polymer networks that exhibit unique responsiveness to external stimuli, such as temperature. While the synthesis of PNIPAM microgels is well-documented, there is limited exploration of how their structural properties can be modified by subtle changes in the polymerization process. In this work, we carefully investigate ho

Proteogenomic Profiling of Treatment-Naïve Metastatic Malignant Melanoma

BACKGROUND: Melanoma is a highly heterogeneous disease, and a deeper molecular classification is essential for improving patient stratification and treatment approaches. Here, we describe the histopathology-driven proteogenomic landscape of 142 treatment-naïve metastatic melanoma samples to uncover molecular subtypes and clinically relevant biomarkers.METHODS: We performed an integrative proteogen

International Organizations and Transnational Corporations at a World Court of Human Rights

This article is based on the author's involvement in preparing a Draft Statute for a future World Court of Human Rights. The proposal seeks to modify the traditional vertical structure of human rights norms by introducing a mechanism for adjudicating claims about human rights violations by actors other than states, including by international organizations (IO) or transnational corporations (TNC).

Time courses for pulmonary oxygen uptake and cardiovascular responses are similar during apnea in resting humans

Introduction: The pulmonary oxygen uptake is reduced during apnea, compared to eupneic baseline, preserving the pulmonary oxygen store. This study elucidates the time course for this reduction, comparing it to the time course for apnea-induced cardiovascular responses. Methods and results: Experiments involved two groups, performing apneas during rest, both without and with cold-water face immersi

In Situ X-Ray Study During Thermal Cycle Treatment Combined with Complementary Ex Situ Investigation of InGaN Quantum Wells

In situ X-ray reciprocal space mapping was performed during the interval heating and cooling of InGaN/GaN quantum wells (QWs) grown via metal–organic vapor phase epitaxy (MOVPE). Our detailed in situ X-ray analysis enabled us to track changes in the peak intensities and radial and angular broadenings of the reflection. By simulating the radial diffraction profiles recorded during the thermal cycle

Investigating SARS-CoV-2 Neutralising Antibody Response in Sheep

SARS-CoV-2 can cause clinical and inapparent disease and mortality in several animals cohabitating with humans, and sheep are susceptible to SARS-CoV-2 due to virus–receptor interactions similar to those in humans. Hence, sheep have the potential to be infected, spread, and develop neutralising antibodies (NAbs) against SARS-CoV-2. The aim of this study was to investigate the prevalence of SARS-Co

Enzymatic conversion of galactosylated glycans by gut bacteria : Structural and functional characterisation of carbohydrate-active enzymes

The human gut microbiome is a highly complex environment, where a myriad of intricate microbiota-microbiota and microbiota-host interactions occur. The human gut microbiota has been associated with both health and disease. The research presented in this thesis focuses on investigating how the butyrate-producing human gut bacterium Roseburia hominis A2-183 (R. hominis) processes β-mannan oligosacch

Growing up : Early-life circumstances and wellbeing throughout life, Sweden 1905–2016

The first years of life are a critical period of development, and circumstances during this period can affect individuals throughout life. But to what extent do disadvantaged circumstances in childhood affect individual wellbeing in later life and for whom? Can interventions in childhood break adversity over the life course? For whom are interventions most effective and why?This thesis aims to invThe first years of life are a critical period of development, and circumstances during this period can affect individuals throughout life.

Islet NO-Synthases, extracellular NO and glucose-stimulated insulin secretion : Possible impact of neuronal NO-Synthase on the pentose phosphate pathway

The impact of islet neuronal nitric oxide synthase (nNOS) on glucose-stimulated insulin secretion (GSIS) is less understood. We investigated this issue by performing simultaneous measurements of the activity of nNOS versus inducible NOS (iNOS) in GSIS using isolated murine islets. Additionally, the significance of extracellular NO on GSIS was studied. Islets incubated at basal glucose showed modes

High-Resolution Transmission Spectroscopy of Gas Giant Atmospheres

The discovery of exoplanets has revealed an intriguing class of planets unlike anything in the Solar System: ultra-hot Jupiters. These gas giants share similarities with Jupiter in size and in their hydrogen- and helium-dominated atmospheres, yet their proximity to their host stars results in vastly different atmospheric conditions. Intense stellar radiation heats them to temperatures exceeding 20

The CuB site in particulate methane monooxygenase may be used to produce hydrogen peroxide

Particulate methane monooxygenase (pMMO) is the most efficient of the two groups of enzymes that can hydroxylate methane. The enzyme is membrane bound and therefore hard to study experimentally. For that reason, there is still no consensus regarding the location and nature of the active site. We have used combined quantum mechanical and molecular mechanical (QM/MM) methods to study the reactivity

Prevalence of mental disorders in young refugees and asylum seekers in European Countries : a systematic review

The European Union member states received about 385,000 asylum applications from children and adolescents below 18 years in 2015, and 398,000 in 2016. The latest political crises and war have led to an upsurge in refugee movements into European countries, giving rise to a re-evaluation of the epidemiology of psychiatric disorders and mental health problems among young refugees and asylum seekers.
