Temperature-Dependent Crystallization Mechanisms of Methylammonium Lead Iodide Perovskite From Different Solvents
Hybrid perovskites are a novel type of semiconductors that show great potential for solution-processed optoelectronic devices. For all applications, the device performance is determined by the quality of the solution-processed perovskite thin films. During solution processing, the interaction of solvent with precursor molecules often leads to the formation of solvate intermediate phases that may d
Racemic Ketamine as an Alternative to Electroconvulsive Therapy for Unipolar Depression: : A Randomized, Open-Label, Non-Inferiority Trial (KetECT)
BackgroundKetamine has emerged as a fast-acting and powerful antidepressant, but no head to head trial has been performed, Here, ketamine is compared with electroconvulsive therapy (ECT), the most effective therapy for depression.MethodsHospitalized patients with unipolar depression were randomized (1:1) to thrice-weekly racemic ketamine (0.5 mg/kg) infusions or ECT in a parallel, open-label, non-
New remains of scandiavis Mikkelseni inform avian phylogenetic relationships and brain evolution
Although an increasing number of studies are combining skeletal and neural morphology data in a phylogenetic context, most studies do not include extinct taxa due to the rarity of preserved endocasts. The early Eocene avifauna of the Fur Formation of Denmark presents an excellent opportunity for further study of extinct osteological and endocranial morphology as fossils are often exceptionally pre
Grand unified origin of gauge interactions and families replication in the standard model
The tremendous phenomenological success of the Standard Model (SM) suggests that its flavor structure and gauge interactions may not be arbitrary but should have a fundamental first-principle explanation. In this work, we explore how the basic distinctive properties of the SM dynamically emerge from a unified New Physics framework tying together both flavor physics and Grand Unified Theory (GUT) c

Understanding election violence in the Philippines : Beware the unknown assassins of may
Despite election violence being a commonly agreed upon phenomena in the Philippines, there has been a dearth in academic research on the topic in recent years, largely due to a lack of reliable information. To address this, our article adapts recognized methods from studies such as Lindsay Shorr Newman’s 2013 paper, together with Stephen McGrath and Paul Gill’s 2014 research on terrorism and elect
Teologi i tiden, avsnitt 24: Kallelse och erkännande - berättelser från de första prästvigda kvinnorna i Svenska kyrkan
Frida Mannerfelt och Alexander Maurits berättar utifrån boken ”Kallelse och erkännande – berättelser från de första prästvigda kvinnorna i Svenska kyrkan” (Makadam förlag) om det unika källmaterial med 34 av de första prästvigda kvinnorna som de har fått tillgång till och som har lett fram till den här boken. I breven framkommer berättelser om vägen fram till prästvigning och de första åren i förs

The Community Inversion Framework v1.0 : A unified system for atmospheric inversion studies
Atmospheric inversion approaches are expected to play a critical role in future observation-based monitoring systems for surface fluxes of greenhouse gases (GHGs), pollutants and other trace gases. In the past decade, the research community has developed various inversion software, mainly using variational or ensemble Bayesian optimization methods, with various assumptions on uncertainty structure
Evaluating GIS based water budget components applicability and availability for the Lagan River catchment
Med hjälp av öppna datakällor från svenska myndigheter om vatten och mark vilka sammanställdes i ett QGIS-program var det möjligt att presentera och åskådliggöra vattenbudgeten i Lagans avrinningsområden. Den sammanlagda vattenmängden i avrinningsområdet kunde uppskattas till 9,36 km3 varav 75,9 % (7,10 km3) är grundvatten och 24,1% (2,26 km3) finns i sjöarna i området. Studien pekar på att GISbasUsing open-access data sets on water and soil from Swedish authorities and compiling them in a QGIS-programme made it possible to present and visualise the water budget of the Lagan River Catchment. Based on the estimations of the water volume in groundwater reservoirs and lakes the total maximum available volume in the Lagan River Catchment area was determined to be 9.36 km3. Of this 75.9% (7.10
The role of coarse aerosol particles as a sink of HNO3 in wintertime pollution events in the Salt Lake Valley
Wintertime ammonium nitrate (NH4NO3) pollution events burden urban mountain basins around the globe. In the Salt Lake Valley of Utah in the United States, such pollution events are often driven by the formation of persistent cold-air pools (PCAPs) that trap emissions near the surface for several consecutive days. As a result, secondary pollutants including fine particulate matter less than 2.5 um
Sweden, Japan, and the Long Second World War : 1931-1945
Lottaz and Ottosson explore the intricate relationship between neutral Sweden and Imperial Japan during the latter's 15 years of warfare in Asia and in the Pacific. While Sweden's relationship with European Axis powers took place under the premise of existential security concerns, the case of Japan was altogether different. Japan never was a threat to Sweden, militarily or economically. Neverthele
Contested numbers: Census controversies and the press in 1960s Nigeria
This article reconstructs the controversies following the release of the figures from Nigeria's 1963 population census. As the basis for the allocation of seats in the federal parliament and for the distribution of resources, the census is a valuable entry point into postcolonial Nigeria's political culture. After presenting an overview of how the Africanist literature has conceptualized the polit
Associations of Red Cell Distribution Width With Coronary Artery Calcium in the General Population
Red cell distribution width (RDW) is a measure of the variability of erythrocyte volumes. RDW has been associated with incidence of cardiovascular diseases. However, the underlying mechanisms for the increased cardiovascular risk are still unclear. This study aimed to examine associations of RDW and coronary atherosclerosis in the general population. Computed tomography was performed and RDW was m
Att vara filosof i en tvärvetenskaplig miljö
Inom den moderna universitetsvärlden är filosofi inte en brett utforskande intellektuell verksamhet utan ett “ämne”, en “disciplin”, med interna normer och traditioner för vad man gör, hur man gör det och vad som är ett filosofiskt problem. Hur filosofi som akademisk disciplin förhåller sig till andra discipliner är en stor fråga, men delvis kan den illustreras av hur det är att som filosof verka
Framtagning av märkning för brandvarnare – Med EURO-NCAP som förebild
The number of traffic-related fatalities has dropped significantly in the last few decades, but the trend in fire safety, albeit positive, show a less rapid improvement. One reason could be the introduction of the Euro-NCAP-system in traffic safety which has been instrumental in promoting innovation in the field. In this report, a first version of a similar system for smoke alarms, arguably a most
Considering the dilemma of societal alignment: A response
The publication of our article “Introducing the dilemma of societal alignment for inclusive and responsible research and innovation” (Ribeiro et al., 2018) was accompanied by three commentaries (Guston, 2018; Nordmann, 2018; and Kuzma and Roberts, 2018). In the original article, we invoked Collingridge’s dilemma of the social control of technology to introduce a complementary dilemma of “societal
A Transition towards Digital Home Visits in Social Care and Home Health Care during the Corona Pandemic
Background: Physical meetings are favoured in social care and home health service in Sweden, both when it comes to internal meetings or home visits at citizens residence. During the pandemic, physical meetings were supposed to decrease as much as possible to avoid the virus to spread. One solution was to digitize as many meetings as possible. Transforming meetings from physical to digital is not w
