1,8-diiodooctane (DIO) additive is an important method for optimizing the morphology and device performance of polythieno[3,4-b]-thiophene-co-benzodithiophene (PTB7)-based polymer solar cells. However, the effect of DIO additive on charge photogeneration dynamics of PTB7-based polymer solar cells is still poorly understood. In this work, the effect of DIO additive on the carrier photogeneration dy

We have studied the accuracy of 16 different density functional theory methods to reproduce experimental data for bond lengths, angles, vibrational frequencies, as well as enthalpies and entropies for the binding of N2, H2, CO and hydride ions to various transition-metal complexes (with Fe, Ni, Cr, Mo andW) with relation to nitrogenase.We show that generalized gradient approximation functionals gi

The presence of charged Higgs bosons is a generic prediction of multiplet extensions of the Standard Model (SM) Higgs sector. Focusing on the Two-Higgs-Doublet-Model (2HDM) with type I and lepton-specific Yukawa sectors, we discuss the charged Higgs boson collider phenomenology in the theoretically and experimentally viable parameter space. While almost all existing experimental searches at the LH

We provide a statistically significant observation of the elusive Odderon exchange, based on novel and model-independent analysis of the scaling properties of the differential cross sections of elastic pp and pp scattering in the TeV energy range. We report the statistical significance of the observed Odderon signal at the level of 6.26 σ.

Background Molecular DNA sequence data allow unprecedented advances in biodiversity assessments, monitoring schemes and taxonomic works, particularly in poorly-explored areas. They allow, for instance, the sorting of material rapidly into operational taxonomic units (such as BINs - Barcode Index Numbers), sequences can be subject to diverse analyses and, with linked metadata and physical vouchers,

Aim: Ongoing climate warming has been widely reported to delay autumn phenology, which in turn impacts carbon, water, energy and nutrient balances at regional and global scales. However, the underlying mechanisms of autumn phenology responses to climate change have not been fully elucidated. The aims of this study were to determine whether brightening that was defined as the increase of surface so

The dynamics of blue and green water partitioning under vegetation and climate change, as well as their different interactions during wet and dry periods, are poorly understood in the literature. We analyzed the impact of vegetation changes on blue water generation in a central Spanish Pyrenees basin undergoing intense afforestation. We found that vegetation change is a key driver of large decreas

Acute lymphoblastic leukemia (ALL) is a highly aggressive pediatric cancer that can affect both B cells and T cells. The advent of new therapies has increased the cure rates for both B-ALL and T-ALL patients. However, some patients still experience relapse with a variable response to the treatment and display poor survival. Thus,identification of novel predictive biomarkers that can predict therap

There is currently an emerging drive towards computational materials design and fabrication of predicted novel materials. One of the keys to developing appropriate fabrication methods is determination of the composition and phase. Here we explore the FeGe system and establish reference Raman signatures for the distinction between FeGe hexagonal and cubic structures, as well as FeGe2and Fe2Ge3phase

While social movement scholars have long recognized the importance of collective memory and shared pasts in the construction of collective identities, less attention has focused on the role of imagined futures. Based on a long-term ethnographic study of radical left-libertarian groups in Sweden, this paper explores the role of utopia in structuring, influencing, and evaluating actions and practice

The aim of this chapter is to show how insights from semiotics cancontribute to psychotherapy, notably the one inspired by Emmanuel Levinas’sethics of the other. Important to this undertaking are Augusto Ponzio’ssemiotic analyses of the ethics of Levinas. Moreover, a study of the Peirceannotion of abduction has proved to be fruitful in the further understanding ofhow psychotherapy can benefit from

The preschool years presents an important opportunity to support children’s social and emotional development. Social and emotional learning (SEL) programs in early childhood education and care (ECEC) have gained an increased interest due to its potential to improve child health and educational outcomes. We aimed to identify existing systematic reviews on universal, curriculum-based SEL interventio

Background Premature ventricular complexes (PVCs) are generally quantified using a 24h ECG recording, but the diagnostic accuracy is unknown. We aimed to determine the day-to-day variability and optimal monitoring duration for PVC measurements among patients with frequent PVCs. Methods We included all patients who underwent a clinical ambulatory ECG recording lasting 25-30 days, using the PocketEC

We have used angle-dependent soft x-ray absorption spectroscopy (XAS) at the O K edge and first-principles calculations to investigate the electronic structures of iridate-based superlattices (SrIrO3)m/(SrTiO3) (m=1, 2, 3, and ∞). We focus on the pre-edge Ir 5d t2g-O 2p orbital hybridization feature in the XAS spectra. By varying the measurement geometry relative to the incident photon polarizatio

Vi välkomnar repliken från Carbon Capture Companys vd. Vi, EU, Sveriges regering och Christoffer Bonde delar målet att främja ett starkt och lönsamt skogsbruk som bidrar till klimat­arbetet både genom upptag av växthus­gaser och minskade utsläpp. Vad vi ställer oss kritiska till är den klimat­kompensation som just nu lanseras av företag som Carbon Capture Company, eftersom vi anser att den är dyr,

The molecular mechanism behind affinity maturation is the introduction of point mutations in immunoglobulin (Ig) V genes, followed by the selective proliferation of B cells expressing mutants with increased affinity for antigen. An in vitro culture system was developed in which somatic hypermutation of Ig V genes was sustained in primed B cells. Cognate T cell help and cross-linking of the surface

Priming mice with a chicken gamma globulin (CGG) carrier protein significantly accelerated the onset of somatic mutation in the V chi Ox1 gene when the mice were subsequently immunized with 2-phenyl-5-oxazolone (phOx) coupled to CGG. The first mutations were already detected 7 days after immunization, while in the true primary response, they are not apparent until day 10. It was also found that co

Resting mouse B lymphocytes were stimulated in vitro with lipopolysaccharide, Sepharose-coupled anti-kappa antibodies or a combination of the two. B lymphocytes stimulated with anti-kappa entered the cell-cycle with more rapid kinetics and at a higher frequency than did the corresponding cell population stimulated with lipopolysaccharide. Using cell cycle analysis after DNA staining combined with
