Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. Traditionally, such PCs are based on scarce and expensive metals, such as ruthenium or iridium, in combination with polypyridyl ligands. Res
Frontotemporal dementia is the second most common form of early onset dementia (<65 years). Despite this, there are few known disease-modifying factors. The anterior cingulate is a focal point of pathology in behavioural variant frontotemporal dementia. Sulcation of the anterior cingulate is denoted by the presence of a paracingulate sulcus, a tertiary sulcus developing, where present during the t
Prenatal insults or adverse events during the in-utero period may lead to suboptimal function of adult organs because of the impairment of critical organ development and growth, as linked to lower birth weight. This may ultimately predispose the individual to the later onset of some diseases in adulthood, a process known as Developmental Origins of Health and Disease (DOHaD). There is ample eviden
Abstract in PortugueseA adoção, apropriação e uso da linguagem dos direitos humanos em discursos ativistas surgiram na década de 1970, em um momento em que ativistas aumentaram a conscientização global sobre a violência e a repressão durante as ditaduras militares no Brasil, Chile e Argentina (Eckel e Moyn, 2014). A violência dessas ditaduras foi um fator crítico no desenvolvimento do ativismo tra
Sedan oktober 2022 styrs Italien av en regering med Giorgia Meloni som premiärminister. Hon är ledare för partiet Fratelli d’Italia och har en bakgrund i två partier med fascistiska rötter: det neofascistiska Movimento Sociale (MSI) och det postfascistiska Alleanza Nationale (AN). Intresset för den italienska fascismen och dess arvtagare har därmed fått ny näring.
The global burden of neurological disorders is substantial and increasing, especially in low-resource settings. The current increased global interest in brain health and its impact on population wellbeing and economic growth, highlighted in the World Health Organization’s new Intersectoral Global Action Plan on Epilepsy and other Neurological Disorders 2022–2031, presents an opportunity to rethink
När Sverige 1950 beslutade att gå med i Bretton Woods-institutionerna (Internationella valutafonden och Världsbanken) uteblev den offentliga debatten fullständigt. När vi nu står inför ännu ett historiskt vägval – EMU – kan vi likväl lära oss något av historien.
Craniopharyngiomas (CPs) are rare primary brain epithelial tumors arising in the suprasellar region from remnants of Rathke's pouch. About 50% originate at the level of the third ventricle floor, including the hypothalamus (HT). CPs are characterized by a low proliferation rate and symptoms due to mass effect and local infiltration and are managed primarily with surgery and radiotherapy. Gross tot
Vi har mycket att lära från länder som Kanada, där civilsamhället spelar en betydligt mer framträdande roll i integrationsarbetet. Det skriver professor emeritus Benny Carlson samt Oskar Adenfelt och Johanna Hemberg, Fores.
Benny Carlson skriver här om Migrationsverkets långa handläggningstider, som kostar samhället pengar: ”Det finns de – flyktingar, anhöriga, studerande, arbetskraftsinvandrare – som är välutbildade och inget hellre vill än att bli självförsörjande, nyttiga och välintegrerade svenska medborgare men som stöter på patrull vart än de vänder sig.”
This article presents new measurements of the fragmentation properties of jets in both proton–proton (pp) and heavy-ion collisions with the ALICE experiment at the Large Hadron Collider (LHC). We report distributions of the fraction zr of transverse momentum carried by subjets of radius r within jets of radius R. Charged-particle jets are reconstructed at midrapidity using the anti-k T algorithm w
This paper presents a measurement of b-jet production in Pb+Pb and pp collisions at sNN=5.02 TeV with the ATLAS detector at the LHC. The measurement uses 260 pb - 1 of pp collisions collected in 2017 and 1.4 nb - 1 of Pb+Pb collisions collected in 2018. In both collision systems, jets are reconstructed via the anti- kt algorithm. The b-jets are identified from a sample of jets containing muons fro
