We show that weakly entangled states can improve communication over a qubit channel using only separate, interference-free, measurements of individual photons. We introduce a communication task corresponding to the cryptographic primitive known as secret sharing and show that all steerable two-qubit isotropic states provide a quantum advantage in the success rate using only product measurements. F
Quantum thermal machines can generate steady-state entanglement by harvesting spontaneous interactions with local environments. However, using minimal resources and control, the entanglement is typically weak. Here, we study entanglement generation in a two-qubit quantum thermal machine in the presence of a continuous feedback protocol. Each qubit is measured continuously and the outcomes are used
Background: Telomere length (TL) and mitochondrial function expressed as mitochondrial DNA copy number (mtDNAcn) are biomarkers of aging and oxidative stress and inflammation, respectively. Methylmercury (MeHg), a common pollutant in fish, induces oxidative stress. We hypothesized that elevated oxidative stress from exposure to MeHg decreases mtDNAcn and shortens TL. Methods: Study participants ar
BACKGROUND: Beneficial effects from practising a Paleolithic diet as compared to a diabetes diet on weight, waist circumference, satiety, leptin, HbA1c and glucose control in randomised controlled trial participants with type 2 diabetes could be due to lower leptin resistance. Support for this hypothesis comes from an in vitro experiment that showed that digested wheat gluten, which is excluded fr
Background: Compression of the greater occipital nerve (GON) may contribute to chronic headache, neck pain, and migraine in a subset of patients. We aimed to evaluate whether GON decompression could reduce pain and improve quality of life in patients with occipital neuralgia and chronic headache and neck pain. Methods: In this retrospective cohort study, selected patients with neck pain and headac
An interesting subset of nanoparticles is core-shell nanoparticles: encapsulating a core particle of one material with a shell of another material can be utilized to combine and even extend the properties of the respective material. Strategies to synthesize core-shell nanoparticles in the aerosol phase remain relatively unexplored, despite the benefit of the continuous, ambient pressure nature of
Over the last years, there have been huge research efforts in the synthesis of advanced nanoparticle heterostructures to promote their performance in photocatalysis.[1] Especially, the combination of metals with semiconductors has been identified as a potential approach to enhance the photocatalytic activity via efficient charge carrier separation enabled by plasmon- exciton coupling.[2] The physi
Analysis of the genomic landscape of prostate cancer has identified different molecular subgroups with relevance for novel or existing targeted therapies. The recent approvals of the poly(ADP-ribose) polymerase (PARP) inhibitors olaparib and rucaparib in the metastatic castration-resistant prostate cancer (mCRPC) setting signal the need to embed molecular diagnostics in the clinical pathway of pat
This overview of progress made in preventing post-traumatic osteoarthritis (PTOA) was delivered in a workshop at the Orthopaedics Research Society Annual Conference in 2019. As joint trauma is a major risk factor for OA, defining the molecular changes within the joint at the time of injury may enable the targeting of biological processes to prevent later disease. Animal models have been used to te
BackgroundThe active thyroid hormone triiodothyronine (T3) has been found to have an estrogen-like effect on breast cancer cells. Thyroid hormone receptor alpha-2 (THRα-2) acts as an antagonist for triiodothyronine (T3) signaling, and a low expression has been associated with unfavorable tumor characteristics and a higher mortality in breast cancer. However, the evidence are not conclusive. The pr
Standard quantum measurements are projective. However, the full scope of quantum measurements is represented by positive operator-valued measures (POVMs) and many of these break the limitations of projective measurements as resources in quantum information. It is therefore natural to consider how accurately an experimenter with access only to projective measurements and classical processing can si
Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to

This thesis examines the interactions and role-changings between the LGBTQIA+ community and the creative industries in Guangzhou, China. Following Florida’s (2003) creative capital theory, and Badgett, Waaldijk, and Rodgers’s (2019) study on LGBT inclusion and economic development, involving semi-structured interviews with LGBTQIA+ individuals working or studying in the creative industries. This q
Purpose: The purpose of this thesis is to increase the effectiveness of the case company, Alfa Laval’s, inventory management by finding challenges, opportunities, and gaps within its current inventory management practices. Background: An essential part of an organization’s planning and control is inventory management, which helps manage supply and demand uncertainty as well as mismatches in upst
Mänskliga attityder är fundamentala för att bevara jordens ekosystem. Denna studie undersökte sambandet mellan mänsklig empati och upplevelsen av samhörighet med naturen, mer specifikt, med specifika växter. Undersökningen baserades på enkäter och den statistiska analysen gjordes med rmANOVA. Deltagarna (N = 106, medelålder =32,7 SD =16,0) bedömde sin empati och upplevelse av samhörighet med naturHuman attitudes toward nature are fundamental for preserving earth’s ecosystems. This study investigated the malleability of human empathy and connectedness to specific plants. We randomly assigned participants (N = 106, Mean age = 32.7, SD = 16.0) to one of three different induction conditions, and measured trait general empathy and connectedness to nature, as well as state empathy and connectedn
In this master’s thesis I will investigate how librarians think about how their profession is affected by and relates to the democratic mission and various cultural policy decisions. I will also attempt to make more clear how librarians interpret, relate and deal with external forces of change such as technology, politics and other social forces. This has been done to investigate and survey the tw
In Swedish, adverbials mainly occur in two positions in the clause: postverbally (last in the clause) or medially (before the finite verb in subordinate clauses and after the finite verb but before e.g. infinite verbs in main clauses). VP adverbials are said to have their natural position postverbally, but they can also be placed medially. This thesis examines factors that influence the placement
Strålbehandling är en viktig behandling av cancer och det är avgörande att ge de föreskrivna stråldoserna exakt på rätt plats för att lyckas. Innan en patient behandlas verifieras strålbehandlingen genom kontrollmätningar. Dessa kontrollmätningar utförs med små detektorer som är placerade i ett fantom. Dessa mäter dosen endast i de punkter där de placeras. Stråldosen som ligger mellan dessa punkteBackground & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. Among various dosimetry techniques
