The paper presents new geological, geochronological, geochemical, and Nd isotopic data on the late Paleoproterozoic dolerites of the Siberian craton. U-Pb baddeleyite ages of the Doros dolerites (Aldan shield, south-eastern Siberia) and East Anabar dolerites (Anabar shield, northern Siberia) are 1757 ± 4 and 1774 ± 6 Ma, respectively. This new geochronological data together with published 1.76–1.7
Pneumatiska bromssystem i tunga fordon är oeffektiva ur energiperspektiv, artikeln beskriver mätningar som jämför pneumatiska och elektromekaniska bromssystem för en batterielektrisk buss.Electric powertrains increase efficiency in road vehicles and enable zero tailpipe emissions, but introduce practical limitations in on board energy storage capacity, due to the low energy density in battery systems when compared with chemical fuels in tanks. The increased powertrain efficiency and lower on-board energy storage levels place focus on other energy consumers in the vehicle system, su
In 2018, an AI system named by its creator DABUS (Device for the Autonomous Bootstrapping of Unified Sentience) was credited by its creator to have independently invented a neural flame and a fractal container. According to its creator, DABUS is a ‘sentient artificial general intelligence can replicate all aspects of human cognition, including perception, creativity, consciousness, and sentience’
We describe key aspects of hypnosis that distinguish it from other psychotherapeuticapproaches, argue that hypnosis occupies a unique niche among clinical interventions, andclaim that a substantial body of evidence supports its use across a gamut of psychologicalconditions. Hypnotic techniques are ideally suited to present useful suggestions that canalter subjective, behavioral, and physiological
For navigation, animals use a robust internal compass. Compass navigation is crucial for long-distance migrating animals like monarch butterflies, which use the sun to navigate over 4,000 km to their overwintering sites every fall. Sun-compass neurons of the central complex have only been recorded in immobile butterflies, and experimental evidence for encoding the animal's heading in these neurons
The emerging notion of hematopoietic stem and progenitor cells (HSPCs) as a low-primed cloud without sharply demarcated gene expression programs raises the question on how cellular-fate options emerge and at which stem-like stage lineage priming is initiated. Here, we investigate single-cell chromatin accessibility of Lineage-, cKit+, and Sca1+ (LSK) HSPCs spanning the early differentiation landsc
I samband med Hovrätten över Skåne och Blekinges 200-årsjubileum har jag tillsammans med hovrätten tagit fram en utställning som finns både fysiskt i hovrättens lokaler i Malmö och digitalt.
To increase industrial adoption, part qualifcation and certifcation of the additive manufacturing (AM) process are crucial through geometric benchmarking as well as optimising the properties and process parameters. However, an extensive researchgap remains concerning the geometric dimensioning and tolerancing (GD&T) of AM parts. This paper presents a review on the state-of-art GD&T benchma
BACKGROUND: Prospective and detailed investigations of smoking and prostate cancer (PCa) risk and death are lacking.OBJECTIVE: To investigate prediagnosis smoking habit (status, intensity, duration, and cessation) as a risk factor, on its own and combined with body mass index (BMI), for PCa incidence and death.DESIGN, SETTING, AND PARTICIPANTS: We included 351448 men with smoking information from
