Agriculture accounts for a large proportion of global greenhouse gas (GHG) emissions. It is therefore crucial to identify effective and efficient GHG mitigation potentials in agriculture, but also in related upstream sectors. However, previous studies in this area have rarely undertaken a cross-sectoral assessment.

Previous research in the Western world shows that men are in general more likely than women to deny human-induced climate change or certain aspects of it. We hypothesize that threatened masculinity contributes to such gender differences in Sweden. Threatened masculinity refers to the perception that a man's masculinity is being challenged, undermined, or devalued, often due to societal changes that advance women's rights.

N-Methyladenosine (m6A) is the predominant internal RNA modification in eukaryotic messenger RNAs (mRNAs) and plays a crucial role in mRNA stability. Here, using human cells, we reveal that m6A sites in the coding sequence (CDS) trigger CDS-m6A decay (CMD), a pathway that is distinct from previously reported m6A-dependent degradation mechanisms. Importantly, CDS m6A sites act considerably faster and more efficiently than those in the 3' untranslated region, which to date have been considered the main effectors.

The self-assembly of NiCl with a chiral bidentate ligand pair, (1,2)-(+)- and (1,2)-(-)-1-(nicotinamido)-2,3-dihydro-1-inden-2-yl nicotinate (,-L and ,-L) in a mixture of ethanol and dioxane, gives rise to stable crystals consisting of [2Cl@NiCl(,-L)(HO)]·4CHO·EtOH and [2Cl@NiCl(,-L)(HO)]·4CHO·EtOH chiral cages, respectively, with two encapsulated chloride anions in the cavities. The most interesting feature is that the self-assembly of NiCl with the mixture of ,-L and ,-L (1 : 1-1 : 4) produces crystals of thermodynamically stable achiral cages, [2Cl·2HO@NiCl(,-L)(,-L)(HO)]·7CHO, in the molar ratio range. Furthermore, the [2Cl@NiCl(,-L)(HO)]·4CHO·EtOH and [2Cl@NiCl(,-L)(HO)]·4CHO·EtOH chiral crystals can recognize the pairs of L-,D-tryptophan and L-,D-cysteine cyclic voltammetry (CV) signals, in contrast to the [2Cl·2HO@NiCl(,-L)(,-L)(HO)]·7CHO achiral crystal.

Mavacamten is the first cardiac myosin inhibitor approved by the US Food and Drug Administration for the treatment of adults with symptomatic obstructive hypertrophic cardiomyopathy (HCM). The phase III EXPLORER-HCM (NCT03470545) study used a dose-titration scheme based on mavacamten exposure and echocardiographic assessment of Valsalva left ventricular outflow tract gradient (VLVOTg) and left ventricular ejection fraction (LVEF). Using population pharmacokinetic/exposure-response modeling and simulations of virtual patients, this in silico study evaluated alternative dose-titration regimens for mavacamten, including regimens that were guided by echocardiographic measures only.

Climate mitigation constitutes an intergenerational moral dilemma; the decisions we make today will inevitably shape the prospects for generations to come. Yet, we still know little about the relationship between intergenerational altruism (IGA)-our concerns for the well-being of future generations-and support for costly climate mitigation policies. In this study, we present an approach to measuring IGA through an intergenerational dilemma, where participants allocate resources across generations.

We report chemically tunable n-type titanium oxides using ethanolamine as a nitrogen dopant source. As the amount of ethanolamine added to the titanium oxide precursor during synthesis increases, the Fermi level of the resulting titanium oxides (ethanolamine-incorporated titanium oxides) significantly changes from -4.9 eV to -4.

Self-assembly of CuX (X = BF, PF, and SbF) with a pair of chiral bidentate ligands, (12)-(+)- and (12)-(-)-1-(nicotinamido)-2,3-dihydro-1-inden-2-yl-nicotinate (-L or -L), in a mixture solvent including ethanol in a glass vessel gives rise to SiF-encapsulated CuL chiral cage products. The SiF anion from the reaction of X with SiO of the glass-vessel surface acts as a cage template or cage bridge. One of the products, [SiF@Cu(SiF)(-L)]·3CHCl·4EtOH, is one of the most effective heterogeneous catalysts for the oxidation of 3,5-di--butylcatechol.

Dark matter elastic scattering off nuclei can result in the excitation and ionization of the recoiling atom through the so-called Migdal effect. The energy deposition from the ionization electron adds to the energy deposited by the recoiling nuclear system and allows for the detection of interactions of sub-GeV/c^{2} mass dark matter. We present new constraints for sub-GeV/c^{2} dark matter using the dual-phase liquid argon time projection chamber of the DarkSide-50 experiment with an exposure of (12 306±184)  kg d.

One of the most important decisions coalition partners make when forming a government is the division of ministries. Ministerial portfolios provide the party in charge with considerable informational and agenda-setting advantages, which parties can use to shape policies according to their preferences. Oversight mechanisms in parliaments play a central role in mitigating ministerial policy discretion, allowing coalition partners to control each other even though power has been delegated to individual ministers.

The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM).

This article explores how emotions connected to the Government's handling of the Covid-19 outbreak in Sweden relates to behaviors to stop the spread of the virus, and which emotions functions as mediators in this relationship. The Swedish approach to handling the outbreak greatly differed from how many other Western European countries handled the situation and thus makes an important case to study. In a large representative survey (N = 2449), we found that satisfaction with how the Government handled the situation was related to more positive and less negative emotions.

Sample sizes for single-period clinical trials, including pharmacokinetic studies, are statistically determined by within-subject variability (WSV). However, it is difficult to determine WSV without replicate-designed clinical trial data, and statisticians typically estimate optimal sample sizes using total variability, not WSV. We have developed an efficient population-based method to predict WSV accurately with single-period clinical trial data and demonstrate method performance with eperisone.
