Signal amplification in molecular sensing by imprinted polymers

In the field of sensing, the development of sensors with high sensitivity, accuracy, selectivity, sustainability, simplicity, and low cost remains a key focus. Over the past decades, optical and electrochemical sensors based on molecular imprinting techniques have garnered significant attention due to the above advantages. Molecular imprinting technology utilizes molecularly imprinted polymers (MI

Development of Optically Communicating Nanowire-based III-V Devices : Optical broadcasting for artificial neural networks

Denna avhandling presenterar utvecklingen och studiet av en flexibel och kiselchip-kompatibel integration av III–V nanotrådsbaserade (NW) optoelektroniska komponenter i nätverkskretsar, där kommunikation sker genom utsändning av ljussignaler. Detta innefattar en undersökning av hur neurala bearbetningsbeteenden kan efterliknas med hjälp av fotoniska kretsar på chip. Både experimentella resultat soThis thesis presents the development and study of a flexible and Silicon-chip compatible integration of III–V nanowire (NW) optoelectronic components in network circuits, where communication is done via the broadcasting of light signals. This includes an investigation into how neural processing behaviours can be emulated using on-chip photonic circuits. Both experimental works that demonstrate the

Long-term pain and health economic outcomes in adults receiving multidisciplinary CBT for chronic pain : the role of psychological inflexibility

BACKGROUND: Little is known about whether the recommended, non-pharmacological treatments for chronic pain yield reductions in healthcare utilization, social costs and increased productivity in actual practice.METHODS: The primary aim of this study ( n = 232) was to conduct secondary analyses of health economic outcomes using data from national registries combined with clinical outcome data from a

RIP #almedalen: The rise and fall of the hashtag of a Swedish democracy festival

Democracy festivals are events that aim to strengthen democracy by engaging citizens, politicians and organisations in dialogue and provide a more equal access to the agenda. In recent years, social media have become important arenas for agenda building, supposedly equalising the access to such processes. This article uncovers patterns of activity and visibility in agenda building through an actor

Responsibilization and Gender Inequality : Navigating Structural Barriers in the Swedish Digital Games Industry

The Swedish digital games industry portrays itself as inclusive and egalitarian, yet structural inequalities persist, particularly for women. Despite progress in gender equality in Sweden, the industry remains male-dominated, with women comprising only 24% of the workforce in 2023. Female game developers often face exclusion, sexism, and limited career opportunities, being relegated to less presti

Ptychographic reconstructions performed in real time and offline have equivalent quality

Ptychography is a burgeoning imaging technique that enables high-resolution, lensless reconstruction of complex samples by analysing overlapping diffraction patterns, making it invaluable in fields like materials science, biology, and nanotechnology. Real-time ptychographic reconstructions are gaining interest in the scientific community as they provide immediate feedback. Yet their potential to r

Zero waste for all? : Sustainable practices in a small-scale zero waste community from a universal design perspective

Since 2003, Kamikatsu in Japan has established a sustainable zero-waste practice that has achieved a recycling rate exceeding 80%. By exploring how the community has shaped itself around the zero-waste concept, this paper aims to enhance our understanding of zero waste in practice from a universal design perspective. Interviews and photo documentation were used to gather data.

Social Preferences and Environmental Externalities

Standard economic theory assumes that consumers ignore the externalities they create, such as emissions from burning fossil fuels and generating waste. In an incentivized study (N = 3, 718), we find that most people forgo substantial gains to avoid imposing negative externalities on others. Using administrative data on household waste, we show a clear link between such prosociality and waste behav

Imprecision plateaus in quantum steering

We study tests of quantum steering in which the trusted party does not have perfect control of their measurements. We report on steering inequalities that remain unaffected when introducing up to a threshold magnitude of measurement imprecision. This phenomenon, which we call an imprecision plateau, thus permits a departure from the standard assumption of idealized measurements without incurring a

Semidefinite Relaxations for High-Dimensional Entanglement in the Steering Scenario

We introduce semidefinite programming hierarchies for benchmarking relevant entanglement properties in the high-dimensional steering scenario. Firstly, we provide a general method for detecting the entanglement dimensionality through certification of the Schmidt number. Its key feature is that the computational cost is independent of the Schmidt number under consideration. Secondly, we provide a m

Machine-learning-based device-independent certification of quantum networks

Witnessing nonclassical behavior is a crucial ingredient in quantum information processing. For that, one has to optimize the quantum features a given physical setup can give rise to, which is a hard computational task currently tackled with semidefinite programming, a method limited to linear objective functions and that becomes prohibitive as the complexity of the system grows. Here, we propose

'Missing Girls' and Reproductive Justice @Beijing+30

This piece considers how we can think critically around prenatal sex selection and the problem of ‘missing girls’ and devise strategies to address this phenomenon without risk of harming the rights and interests of girls and women. To address the problem of ‘missing girls’ our research findings suggest there is a need to move beyond a rights-based approach towards gender and reproductive justice,

Landscape composition can influence reproductive success of plants in semi-natural grasslands depending on their pollinator dependence

In a world where insect pollinator declines are a reality, understanding their effects on the reproduction and persistence of wild plant species is vital to contribute to decisions for appropriate conservation strategies. This is especially true in areas which host a high species diversity, like European semi-natural grasslands. In fragmented habitats in particular, pollinator availability can be

Sex artiklar om skönlitterär prosa : Med förslag till vidare läsning

I denna bok återpublicerar jag sex artiklar om den moderna skönlitterära svenska prosan. Två av artiklarna ger fördjupade analyser av Kerstin Ekmans romaninledningar i Urminnes tecken (2000) respektive Skraplotter (2003). En handlar om kvantitativ metod som redskap vid stilanalys. Övriga artiklar behandlar den skönlitterära prosan som språkligt material och tar upp tempusbruk, interpunktion och or

In the Mood for Likes : A Longitudinal Study of Civil Society Organizations’ Emotional Communication on Social Media

Emotional communication, especially through social media platforms, has become a contemporary populist threat. While this phenomenon has been studied in for example news media and social movements, we know less about its influence on civil society organizations, despite their pluralism being a centerpiece in a vibrant democracy. More specifically, we do not know if social media make civil society

Assessing the transaction costs of residential solar photovoltaic acquisition

Generating electricity from solar photovoltaics (PVs) has massive potential, but realising this potential will require a genuine understanding of transaction costs associated with the adopters' acquisition of the technology. The objective of this study is thus to empirically assess the transaction costs that solar PV adopters carry when proceeding with an acquisition process. Data on transaction c
