Y6 is a new type of non-fullerene acceptor, which has led to power conversion efficiencies of single-junction polymer solar cells over 17% when combined with a careful choice of polymeric donors. However, the excited state characteristics of Y6, which is closely correlated with its opto-electronic applications, are not clear yet. In this work, we studied the excited state properties of the Y6 solu
Documentation is the process of recording, examining, analyzing, and archiving information in order to present it to researchers, interested individuals, students, and decision-makers, which entails taking specific policies, strategies, and plans based on that information later on. The article discusses the importance of the documentation process in defending the minorities in Yemen.
Genom regler formulerade på ett språk och med förklaringar som människor förstår kan automatiserade beslutsgrunder visas och granskas. Det skriver Odd Steen, docent i informatik vid Lunds universitet.
Non-photochemical quenching (NPQ) is an important photoprotective mechanism in plants and algae. Although the process is extensively studied, little is known about its relationship with ultrastructural changes of the thylakoid membranes. In order to better understand this relationship, we studied the effects of illumination on the organization of thylakoid membranes in Monstera deliciosa leaves. T
Smokers are at increased risk for surgical complications. Despite the known benefits of smoking cessation, many perioperative health care providers do not routinely provide smoking cessation interventions. The variation in delivery of perioperative smoking cessation interventions may be due to limited high-level evidence for whether smoking cessation interventions used in the general population ar
Measurement of Z-boson production in p-Pb collisions at sNN = 8.16 TeV and Pb-Pb collisions at sNN = 5.02 TeV is reported. It is performed in the dimuon decay channel, through the detection of muons with pseudorapidity −4 < ημ< −2.5 and transverse momentum pTμ> 20 GeV/c in the laboratory frame. The invariant yield and nuclear modification factor are measured for opposite-sign dimuons with invarian
Inclusive and differential cross-sections for the production of top quarks in association with a photon are measured with proton-proton collision data corresponding to an integrated luminosity of 139 fb−1. The data were collected by the ATLAS detector at the LHC during Run 2 between 2015 and 2018 at a centre-of-mass energy of 13 TeV. The measurements are performed in a fiducial volume defined at p
Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), causing Coronavirus Disease 19 (COVID-19), emerged at the end of 2019 and quickly spread to cause a global pandemic with severe socio-economic consequences. The early sequencing of its RNA genome revealed its high similarity to SARS, likely to have originated from bats. The SARS-CoV-2 non-structural protein 10 (nsp10) displays high sequ
Under de senaste åren har västeuropeiska bedömare uttryckt oro över utvecklingen i Ungern och Polen. En ny spricka mellan Väst- och Östeuropa har tagit form, vilket märktes till exempel i samband med valet till Europaparlamentet förra året. Inte minst uppfattas Ungerns premiärminister Viktor Orbán och Frankrikes president Emmanuel Macron som representanter för ett östligt, bakåtblickande respektiv
The transitions to a low carbon and sustainable society are urgent, but at the current level and pace of action there is a significant risk we will escalate and exceed the goals of the Paris Climate Agreement and fail to achieve the Sustainable Development Goals. By engaging cities, we can build momentum around bottom-up interconnected actions and accelerate societal and technological transitions.
“Garden phlox ‘Alma Jansson’ comes from a smallholding in Roslagen. It has been on the farm at least since 1939 when Stina Jansson moved in. It was her mother-in-law, Alma Jansson, who took care of the plants in the garden. ‘Everything comes from Grandma. She had such beautiful flowers’, said Stina. We do not know where she received or bought this variety, but it was not newly planted in 1939.” Th
To shed light on the interaction between macroprudential and monetary policies, we study the inward transmission of foreign monetary policy in conjunction with domestic macroprudential and monetary policies in Norway and Sweden. Using detailed bank‐level data, we show how Norwegian and Swedish banks’ lending reacts to monetary policy surprises arising abroad, controlling for the domestic macroprud
We report the evolution of metastable precursor structures during hydrogen infusion in the near-surface region of a super duplex stainless steel. Grazing-incidence x-ray diffraction was employed to monitor, operando, the lattice degradation of the austenite and ferrite phases. Electrochemical hydrogen charging resulted in the splitting of the diffraction peaks of the austenite phase, suggesting th
One of the earliest preserved Sanskrit works on Perso-Arabic (Tājika) astrology, the thirteenth-century Karmaprakāśa of Samarasiṃha (also known as the Manuṣyajātaka, Tājikatantrasāra or Gaṇakabhūṣaṇa), is examined with particular attention to subgenre, distinctive content and likely Arabic-language sources. On the basis of a comparison of the extant text of the Karmaprakāśa with excerpts attribute
A close examination of the lists of planetary exaltations given by two of the earliest known Sanskrit authors on horoscopic astrology – Mīnarāja and Sphujidhvaja – solves the confusion surrounding Mīnarāja’s idiosyncratic assignment of degrees and suggests that both authors, and indeed all later Indian astrological literature, depended for this doctrine on a single, Greek-language source.
The Jewel of Annual Astrology is an encyclopaedic treatise on Tājika or Sanskritized Perso-Arabic astrology, dealing particularly with the casting and interpretation of anniversary horoscopes. Authored in 1649 CE by Balabhadra Daivajña, court astrologer to Shāh Shujāʿ – governor of Bengal and second son of the Mughal emperor Shāh Jahān – it casts light on the historical development of the Tājika s
The current threats of climate change are driving attention away from the petrochemical industry towards more sustainable and bio‐based production processes for fuels and speciality chemicals. These processes require suitable low‐cost starting material. One potential material assessed here is the oat hull. Its overall chemical composition has so far not been fully characterized. Furthermore, it is
Gardeners have always used plants of different origins, moving them around to new environments, working hard to make the plants survive and thrive under new conditions. Certain plant varieties have proved to be particularly vital, have a long history as cultivars, and are today understood as heritage plants. Many have spread over centuries and are today regarded as ‘belonging’ and as more or less Gardeners have always used plants of different origins, moving them around to new environments, working hard to make the plants survive and thrive under new conditions.
