Accurate solution-adaptive finite difference schemes for coarse and fine grids
We introduce solution dependent finite difference stencils whose coefficients adapt to the current numerical solution by minimizing the truncation error in the least squares sense. The resulting scheme has the resolution capacity of dispersion relation preserving difference stencils in under-resolved domains, together with the high order convergence rate of conventional central difference methods

Yttrande över remissen: En ny Riksbankslag (SOU 2019:46)
Lunds universitet har uppmanats att ge synpunkter på rubricerad remiss. Universitetet lämnar här följande kommentarer vilka har utarbetats vid Ekonomihögskolan vid Lunds universitet av docent Fredrik N G Andersson och professor emeritus Lars Jonung. Inflationsmålet infördes för över 25 år sedan. Villkoren för att bedriva penningpolitik har förändrats på ett omvälvande sätt under detta kvartssekel.

Identification of the high risk hip fracture patients
Background: Hip fractures are common in older individuals entailing considerable risk of morbidity and mortality. Instruments are needed to enhance risk stratification of hip fracture patients. There is limited knowledge of the role of biomarkers as risk prognosticators for mortality in hip fracture patients.Aims: We assessed how well two well known risk stratification tools performed in a cohort
Six commonly used empirical body surface area formulas disagreed in young children undergoing corrective heart surgery
Aim: Formulas for empirical body surface area (BSA), which is used to estimate body size and standardise physiological parameters, may disagree in children. We compared six commonly used BSA formulas—Du Bois, Boyd, Costeff, Haycock, Meban and Mosteller—in a surgical cohort. Methods: This retrospective single-centre cohort study comprised 68 children who had corrective heart surgery at Skåne Univer

Imagination
Imagination is a human capacity that reproduces and transforms experiences and thoughts. The capacity is manifested in children’s pretend play and is an important part of adults’ ability to process the past, and to plan the future. A first step in the development of imagination is the ability to represent objects and events and to change these representations into alternatives to reality. For adap
Transsynaptic tracing and its emerging use to assess graftreconstructed neural circuits
Fetal neural progenitor grafts have been evaluated in preclinical animal models of spinal cord injury and Parkinson’s disease for decades, but the initial reliance on primary tissue as a cell source limited the scale of their clinical translatability. With the development of robust methods to differentiate human pluripotent stem cells to specific neural subtypes, cell replacement therapy holds ren
Coordination crosslinking of helical substituted oligoamide nanorods with Cu(II)
Substituted oligoamides are short sequences of unnatural amino acids. Oligoamides made entirely of β3 amino acids yield helical monomers that, if N-acylated, assemble into nanorod structures via a supramolecular assembly motif. In this work, coordination crosslinking was used to create complex nanomaterials from oligoamides WKLWEL (KE) and WELWEL (EE) (the letters denote the analogous α-amino acid
Exposure to maternal obesity programs sex differences in pancreatic islets of the offspring in mice
AIMS/HYPOTHESIS: Obesity during pregnancy increases offspring type 2 diabetes risk. Given that nearly half of women of child-bearing age in many populations are currently overweight/obese, it is key that we improve our understanding of the impact of the in utero/early life environment on offspring islet function. Whilst a number of experimental studies have examined the effect of maternal obesity
Physical exercise as a preventive strategy for disorders affecting the brain. The effect on neuroinflammation.
Physical activity is associated with lower risks of developing dementia, Parkinson’s disease (PD) and depression. Furthermore, being physically active prior to brain ischemia appears to help the recovery process. However, previous studies do not differentiate between the two most common forms of dementia, Alzheimer’s disease (AD) and vascular dementia (VaD), when it comes to the association betwee
Hyperparathyroidism and parathyroidectomy in patients on renal replacement therapy
Background. Secondary hyperparathyroidism (sHPT) is characterized by over function of the parathyroid glands and disturbances in mineral metabolism as a result of renal failure. It is common among patients with end-stage renal disease (ESRD) and it often persists after successful renal transplantation. sHPT is associated with osteoporosis and cardiovascular morbidity and mortality. There are two mBackground. Secondary hyperparathyroidism (sHPT) is characterized by over function of the parathyroid glands and disturbances in mineral metabolism as a result of renal failure.

Investigating ultrafast carrier dynamics in perovskite solar cells with an extended π-conjugated polymeric diketopyrrolopyrrole layer for hole transportation
Here, we show a new diketopyrrole based polymeric hole-transport material (PBDTP-DTDPP, (poly[[2,5-bis(2-hexyldecyl)-2,3,5,6-tetrahydro-3,6-dioxopyrrolo[3,4-c]pyrrole-1,4-diyl]-alt-[[2,2′-(4,8-bis(4-ethylhexyl-1-phenyl)-benzo[1,2-b:4,5-b′]dithiophene)bis-thieno[3,2-b]thiophen]-5,5′-diyl]])) for application in perovskite solar cells. The material performance was tested in a solar cell with an optim
Oxidative damage to lipids is rapidly reduced during migratory stopovers
Most migrating birds need to stopover in between flights in order to refuel. Lately, additional purposes of stopover have been suggested, including physiological recovery from metabolically demanding migratory flight. One apparently unavoidable, but harmful physiological effect of migratory flight is increased oxidative damage to lipids and proteins. We here, for the first time, tested whether mig
Unique spectral signature of human cutaneous squamous cell carcinoma by photoacoustic imaging
Cutaneous squamous cell carcinoma (cSCC) is a common skin cancer with metastatic potential. To reduce reoperations due to nonradical excision, there is a need to develop a technique for identification of tumor margins preoperatively. Photoacoustic (PA) imaging is a novel imaging technology that combines the strengths of laser optics and ultrasound. Our aim was to determine the spectral signature o
