By combining ultrashort laser pulses with PEEM, time-resolved photoemission electron microscopy (TRPEEM) provides a powerful approach for investigating ultrafast charge carrier dynamics with simultaneous femtosecond temporal resolution and nanometer spatial precision. It has evolved into a versatile methodto study a wide range of phenomena, including charge carrier dynamics, surface plasmons, scat
Har du som lärare funderat på vad motivationen betyder för elevernas språkinlärning? Har du funderat på om olika aktiviteter i klassrummet kan skapa eller öka elevernas motivation för att lära sig språk? Detta är ett område som inte beforskats så mycket som man kanske tror, trots att skolämnet moderna språk brottas med avhopp och bristande motivation. Vi beskriver här ett forskningsprojekt som und
Migratory songbirds have an internal circannual genetic programme that controls the timing and extent of migratory flight activity, as demonstrated by experiments with birds held in cages. We used multisensor data loggers to record the timing and duration of all migratory flights during the annual cycle of 15 free-living individuals of red-backed shrikes Lanius collurio. Annual actograms unexpecte
BACKGROUND: Cluster headache (CH) is a rare primary headache disorder characterized by recurrent episodes of strictly unilateral excruciating pain accompanied by trigemino-autonomic signs, which significantly impacts the quality of life, social interactions, and occupational functioning of those who are affected. To promote a better understanding of this disabling condition and to foster research
Under 2022 och 2023 ökade livsmedelspriserna kraftigt. Även energipriserna steg kraftigt under 2022. För att motverka den stigande inflationen höjde Riksbanken styrräntan. Sammantaget medförde det betydande kostnadsökningar för de svenska hushållen. I detta projekt har vi studerat hur prisökningarna har påverkat livsmedelsförsäljningen inom detaljhandeln och kostintaget på befolkningsnivå. Analyse
Tumor associated neutrophils (TANs) exert dual and opposing functions in tumors, acting pro-tumorigenic and anti-tumorigenic, depending on tumor progression, polarization state and subtype. Consequently, the prognostic impact of TANs in breast cancer is also contradictory. Since neutrophils are critically needed to fight infections in cancer patients, the mediators leading to tumor progression nee
Oxy-fuel combustion is regarded as an underpinning technology for carbon capture and utilization. Ethane (C2H6) is the primary non-methane component in natural gas and a fundamental C2 fuel. In this work, laminar burning velocities (LBV) of C2H6/O2/CO2 mixtures were measured using the heat flux method at atmospheric pressure, spanning initial temperatures of 308–348 K, equivalence ratios of 0.6–1.
Background: Knee replacement (KR) is the most common osteoarthritis (OA) related surgery. Studies suggest that there are major international and national disparities in pre-operative information, support and access to rehabilitation which have a substantial impact on patients’ perceived outcomes of the KR. The aim of this qualitative study was to explore experiences and perceptions of the care pat
Background: Tumor immune cell infiltration is a favorable prognostic factor in triple-negative breast cancer. Most triple-negative tumors belong to the aggressive basal-like subtype. We hypothesized that immune gene expression may identify low-risk patients for whom adjuvant chemotherapy can be de-escalated. Methods: The expression of 753 immune-related genes was analyzed in tumor biopsies from 45
Background: Microscopic colitis (MC) is characterized by non-bloody, watery diarrhea predominantly in elderly women. Known risk factors are smoking, medication with NSAIDs, PPIs or SSRIs, while data on hormonal factors is sparse. The aim of the present study was to investigate whether hormonal factors that disrupt the sex hormonal balance could have an impact on the disease course in MC. Methods:
Background: The aim of this study was to develop a method for personalized training of Deep Neural Networks by means of an MRI simulator to improve MOLLI native T1 estimates relative to conventional fitting methods. Methods: The proposed Personalized Training Neural Network (PTNN) for T1 mapping was based on a neural network which was trained with simulated MOLLI signals generated for each individ
Animal research show that a novel exploration task performed shortly before a learning episode can strengthen hippocampal memory consolidation through behavioural tagging mechanisms. The aim of the present study was to conceptually translate behavioural tagging results to humans using a novel exploration task in virtual reality. Mimicking conditions for animal research, sixty participants underwen
Frameshifts can be caused by specific combinations of tRNA and mRNA. The wildtype AGC-decoding E. coli tRNASer3GCU has been shown to induce −1 ribosomal frameshifting on GCA alanine codons, and proposed to read a two-base codon instead of a canonical triplet. However, it has remained unclear whether this type of non-cognate decoding can be accommodated by the ribosome. Here, we perform single-part
Background: The routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening. Methods: This was a post hoc analysis of the TTM2-trial,
