Många system kan representeras som grafer, alltifrån neurala nätverk och transportnätverk till något så vardagligt som våra umgängeskretsar. Om exempelvis Andrea är vän med Jona- than, så kan vi rita ut Andrea och Jonathan som var sin prick på ett paper och låta deras vän- skap representeras av en linje. På samma sätt kan vi enkelt lägga till fler personer (prickar) och rita fler linjer till alla There are many systems which can be represented as graphs, to say the least the networks in which we communicate with each other. Thorough understanding of graph structures enables better predictions of the dynamics in real life networks, such as the spreading of a disease in a community or failure propagation in a system. This thesis investigates information propagation over connected undirected

To increase engagement with science and technology, young people around the world are encouraged to attend activities at science centers. But how effective are these activities? Since women have weaker ability beliefs and interest in technology than men, it is especially important to learn how science center visits affect them. In this study, we tested if programming exercises offered to middle sc

Background Celiac disease has an increasing incidence worldwide and is treated with lifelong adherence to a gluten-free diet. We aimed to describe gluten-free diet adherence rates in children with screening-identified celiac disease, determine adherence-related factors, and compare adherence to food records in a multinational prospective birth cohort study. Methods Children in The Environmental De

Background Intravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from

The incidence of human papillomavirus-positive (HPV+) tonsillar cancer has been sharply rising during the last decades. Myeloid cells represent an appropriate therapeutic target due to their proximity to virus-infected tumor cells, and their ability to orchestrate antigen-specific immunity, within the tonsil. However, the interrelationship of steady-state and inflammatory myeloid cell subsets, and

Background: The vast majority of covid-19 patients experience non-severe disease. Nonetheless, long-term symptoms may be common and the impact on quality of life is uncertain. This study aims to examine these aspects in a prospective, longitudinal cohort. Methods: Non-hospitalised patients with PCR-confirmed covid-19 were prospectively invited to self-report assessments of background data, symptom

The Swedish Society of Uroradiology has revised their computed tomography (CT) guidelines regarding iodine contrast media-induced acute kidney injury (CI-AKI). They are more cautious compared to the European Society of Urogenital Radiology and the American College of Radiology since the actual risk of CI-AKI remains uncertain in patients with moderate to severe kidney damage due to a lack of prosp

Skellefteå is calibrating its position in multiple overlapping maps, sometimes located in the centre and sometimes in the periphery (if those are even relevant). It is a place in between places. A geographical periphery of Europe that becomes one of the centres of production of one of the fastest growing industries in the world. The favourable policies to facilitate multimillionaire investments i

BACKGROUND: Mild hypothermia, 32-35°C, reduces infarct size in experimental studies, potentially mediating reperfusion injuries, but human trials have been ambiguous. To elucidate the cardioprotective mechanisms of mild hypothermia, we analyzed cardiac performance in a porcine model of ischemia/reperfusion, with serial cardiovascular magnetic resonance (CMR) imaging throughout one week using non-i

Madagascar’s unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar’s terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats, ex situ collections and programs, and t

Skillnaderna i förutsättningar och möjligheter mellan olika delar av landet harökat (SOU, 2017:1). Framförallt tycks utvecklingen på landsbygden och stadensinvandrartäta områden gå i fel riktning. För både landsbygden och deinvandrartäta områdena riskerar ett växande kulturellt och ekonomisk gapgentemot majoritetssamhället göda splittring och politisk polariseringen.Polariseringen i Sverige är for

Neuroblastoma is a childhood cancer derived from the sympathetic nervous system. High-risk neuroblastoma patients have a poor overall survival and account for ~15% of childhood cancer deaths. There is thus a need for clinically relevant and authentic models of neuroblastoma that closely resemble the human disease to further interrogate underlying mechanisms and to develop novel therapeutic strateg

Övergivna återvinningscentraler på flera platser i Skåne har under det senaste året varit ett omtalat ämne. I Sverige finns ett hundratal fastigheter som saknar ägare. En fastighet kan bli herrelös genom att en konkursförvaltare väljer att överge fastigheten under pågående konkurs om fastighetens ekonomiska värde är negativt. Förfarandet har kommit att benämnas som abandonering i svensk rätt. Det In recent times, it has been a debated topic with abandoned recycling centers in several places in Skåne. There are about a hundred abandoned properties in Sweden that lack an owner. A way for a property to become abandoned is for a bankruptcy trustee to choose to abandon the property, in bankruptcy if the property has a negative value. The procedure is referred to as abandonment. There are no law

Clinical pain is often linked to poor body mechanics, with individuals sometimes presenting multiple painful disorders. Such disorders may be influenced by behaviors that affect the general resiliency and health of the musculoskeletal system. We aimed to develop a self-reported scale using the Malmö Diet and Cancer Study questions on work-related body mechanical exposures. An expert panel identifi
