Characterization of Emerging Non-Volatile Cryogenic Memories

In this thesis, two emerging non-volatile memories, being the resistive random access memory and a ferroelectric capacitor were characterized at cryogenic temperatures. This was carried out due to the demand for non-volatile CMOS compatible cryogenic memories for quantum computing applications. Both devices exhibit good switching characteristics, endurance >10^7 cycles and multilevel capability. M

Design of a Cloaked Dipole Antenna for a Multifunctional Aperture for 5G

With the advent of 5G technology, there is a growing need for advanced antennas that can support multifunctional apertures efficiently and with minimal interference, especially at millimeter-wave (mmWave) frequencies. The thesis addresses this challenge by designing, simulating, and evaluating a cloaked dipole antenna designed for 5G applications. The main concept of this work is a cloaking mechan

In situ Characterization of Deformation Mechanisms in Harmonic Structure Nickel

There is an ever-increasing demand for structural metals with higher strength. Metals can be strengthened by reducing grain size in their microstructure, but ductility is also concomitantly reduced. High strength and ductility are a desirable combination of properties for most structural engineering materials. By arranging fine grains in a continuous network that surrounds islands of coarse grains

Packet-Type Aware Scheduling of Moldable Streaming Tasks on Multicore Systems with DVFS

We introduce a novel approach for energy-efficient scheduling of data-dependent stream programs with packet types on multicore architectures with voltage and frequency scaling. To have the given application meet specific throughput demands while minimizing energy consumption, we enhance the existing crown scheduling by packet-type dependent parameters. Formulation as an integer linear program gene

Policy implications of challenges and opportunities for district heating – The case for a Nordic heating system

District heating (DH) is an efficient urban heating solution. Numerous external factors (energy efficiency, fuel-price increases, heat -pump competition and policy changes) are challenging. It is relevant to explore long-term cost-competitiveness of DH. A model has been developed testing three, future DH pathways: (i) phase out of biomass (aligned to the cascading principle of the EU Taxonomy), (i

A clarification of the conditions under which Large language Models could be conscious

With incredible speed Large Language Models (LLMs) are reshaping many aspects of society. This has been met with unease by the public, and public discourse is rife with questions about whether LLMs are or might be conscious. Because there is widespread disagreement about consciousness among scientists, any concrete answers that could be offered the public would be contentious. This paper offers th

Natural Course of Electrocardiographic Features in Arrhythmogenic Right Ventricular Cardiomyopathy and Their Relation to Ventricular Arrhythmic Events

BACKGROUND: Electrocardiographic abnormalities are common in arrhythmogenic right ventricular cardiomyopathy and are included in the 2010 Task Force Criteria. Their time course, however, remains uncertain. In this retrospective observational study, we aimed to assess the long-term evolution of electrocardiographic characteristics and their relation to ventricular arrhythmias. METHODS AND RESULTS:

Origin of the anisotropic Beer-Lambert law from dichroism and birefringence in β-Ga2O3

The anisotropic optical absorption edge of β-Ga2O3 follows a modified Beer-Lambert law having two effective absorption coefficients. The absorption coefficient of linearly polarized light reduces to the least absorbing direction beyond a critical penetration depth, which itself depends on polarization and wavelength. To understand this behavior, a Stokes vector analysis is performed to track the p

Comparative proteomic analyses of potato leaves from field-grown plants grown under extremely long days

There are limited molecular data and few biomarkers available for studies of field-grown plants, especially for plants grown during extremely long days. In this study we present quantitative proteomics data from 3 years of field trials on potato, conducted in northern and southern Sweden and analyze over 3000 proteins per year of the study and complement the proteomic analysis with metabolomic and

Engagement of stakeholders in action-oriented education for sustainability: a study of motivations and benefits and development of a process model

PurposeEngagement of non-academic stakeholders is an important element of education for sustainability, but is rarely mentioned in contemporary agricultural education literature. This article investigates the process of engagement of non-academic stakeholders into higher education programs on agriculture. Non-academic stakeholders refer to private firms that are focused on the acquisition of knowl

Threats to Validity in Software Engineering – hypocritical paper section or essential analysis?

Background: In recent years, a discourse on how to systematically consider and report threats to validity started to gain momentum within the empirical software engineering community. Aims: With this study, we aim to systematically underpin the current state of threats to validity practices in software engineering research. Method: We conduct a literature review comprising 91 papers awarded with t

Phonological influence in bilectal speakers of Brazilian and European Portuguese

Aims and objectives:This article investigates naturalistic acquisition of a second dialect (D2), comparing the global accent of speakers of Brazilian Portuguese (BP) exposed to European Portuguese (EP), either as children or as adults (early vs late bilectals). The focus is on the predicted advantage of an early age of onset of the D2, as well as possible crosslinguistic influence from the D2 onto

Assessment of DNA quality for whole genome library preparation

In recent years, more sophisticated DNA technologies for genotyping have enabled considerable progress in various fields such as clinical genetics, archaeogenetics and forensic genetics. DNA samples previously rejected as too challenging to analyze due to low amounts of degraded DNA can now provide useful information. To increase the chances of success with the new methodologies, it is crucial to

Hydrogen reduction of iron ore pellets : A surface study using ambient pressure X-ray photoelectron spectroscopy

Using Ambient Pressure X-ray Photoelectron Spectroscopy (APXPS), this study investigates the reduction behavior of iron oxides in direct reduction (DRI) and blast furnace (BF) pellets. H2, CO, and a H2–CO mixture are used as reducing agents at 650 °C. The investigation aimed to elucidate variations in the rate of reduction over time and under different conditions. Additionally, contour plots are g

Chiral Bell-State Transfer via Dissipative Liouvillian Dynamics

Chiral state transfer along closed loops in the vicinity of an exceptional point is one of the many counterintuitive observations in non-Hermitian physics. The application of this property beyond proof-of-principle in quantum physics, is an open question. In this work, we demonstrate chiral state conversion between singlet and triplet Bell states through fully quantum Liouvillian dynamics. Crucial

Resensitization to colistin results in rapid and stable recovery of adherence, serum resistance and ompW in Acinetobacter baumannii

BACKGROUND: Colistin resistance in Acinetobacter baumannii is an emerging problem that limits antimicrobial therapy options.MATERIALS & METHODS: We isolated two pairs of colistin susceptible and colistin-resistant A. baumannii (K1007/K1006 and K408/K409) from two patients diagnosed with carbapenem-resistant A. baumannii infection. Colistin susceptible isolates were exposed to in vitro colistin
