Energy level offsets determine the interplay between charge and energy transfer in all-small-molecule organic solar cells

All-small-molecule organic solar cells (ASM OSCs) hold great promise in OSCs owing to their defined structures, simple purification, and good reproducibility, but are challenging for further improved efficiency. The energy level strategy has been broadly applied to obtain a better performance; however, a comprehensive understanding of the effects of energy level offset on photoexcitation dynamics

Proenkephalin as a biomarker correlates with acute kidney injury: a systematic review with meta-analysis and trial sequential analysis

BackgroundProenkephalin A 119-159 (PENK) is freely filtered in the glomerulus with plasma levels correlating with glomerular filtration rate. Therefore, PENK has been proposed as an early indicator of acute kidney injury (AKI) although its performance is dependent on the clinical setting. This meta-analysis aimed to investigate the correlation between PENK levels and the development of AKI.Methods

Step edge structures on the anatase TiO2 (001) surface studied by atomic-resolution TEM and STM

Low-coordinate surface sites, such as those present on high-index step edges, often exhibit chemical reactivity that markedly differs from more close-packed facets. To understand the site-specific reactivity, insight into the three-dimensional atomic arrangement of step edges is needed. Here, we employ atomic-resolution transmission electron microscopy (TEM) of nanoparticles in combination with sc

Visualizing atomic-scale redox dynamics in vanadium oxide-based catalysts

Surface redox processes involving oxygen atom exchange are fundamental in catalytic reactions mediated by metal oxides. These processes are often difficult to uncover due to changes in the surface stoichiometry and atomic arrangement. Here we employ high-resolution transmission electron microscopy to study vanadium oxide supported on titanium dioxide, which is of relevance as a catalyst in, e.g.,

On the role of the gas environment, electron-dose-rate, and sample on the image resolution in transmission electron microscopy

The introduction of gaseous atmospheres in transmission electron microscopy offers the possibility of studying materials in situ under chemically relevant environments. The presence of a gas environment can degrade the resolution. Surprisingly, this phenomenon has been shown to depend on the electron-dose-rate. In this article, we demonstrate that both the total and areal electron-dose-rates work

Coherence Estimation Tracks Auditory Attention in Listeners with Hearing Impairment

Coherence estimation between speech envelope and electroencephalography (EEG) is a proven method in neural speech tracking. This paper proposes an improved coherence estimation algorithm which utilises phase sensitive multitaper cross-spectral estimation. Estimated EEG coherence differences between attended and ignored speech envelopes for a hearing impaired (HI) population are evaluated and compa

Effect of uncertainty of material parameters on stress triaxiality and Lode angle in finite elasto-plasticity—A variance-based global sensitivity analysis

This work establishes a computational framework for the quantification of the effect of uncertainty of material model parameters on extremal stress triaxiality and Lode angle values in plastically deformed devices, whereby stress triaxiality and Lode angle are accepted as key indicators for damage initiation in metal forming processes. Attention is paid to components, the material response of whic

Impact of velocity- and acceleration-compensated encodings on signal dropout and black-blood state in diffusion-weighted magnetic resonance liver imaging at clinical TEs

Purpose The study aims to develop easy-to-implement concomitant field-compensated gradient waveforms with varying velocity-weighting (M1) and acceleration-weighting (M2) levels and to evaluate their efficacy in correcting signal dropouts and preserving the black-blood state in liver diffusion-weighted imaging. Additionally, we seek to determine an optimal degree of compensation that minimizes sign

Automatic time-frequency analysis of echolocation signals using the matched Gaussian multitaper spectrogram

High-resolution time-frequency (TF) images of multi-component signals are of great interest for visualization, feature extraction and estimation. The matched Gaussian multitaper spectrogram has been proposed to optimally resolve multi-component transient functions of Gaussian shape. Hermite functions are used as multitapers and the weights of the different spectrogram functions are optimized. For

The role of T cells and myeloid-derived suppressor cells in refractory immune thrombocytopenia

Immune thrombocytopenia (ITP) is characterized by a dysregulated immune response against platelets, affecting both their destruction and production. A role for an abnormal T-cell compartment has been established in ITP pathogenesis and treatments that increase platelet counts in patients with ITP have shown improvements in T-cell profiles. On the other hand, patients who were refractory to treatme

Discordance Between Creatinine-Based and Cystatin C–Based Estimated GFR : Interpretation According to Performance Compared to Measured GFR

Rationale & Objective: Use of cystatin C in addition to creatinine to estimate glomerular filtration rate (estimated glomerular filtration rate based on cystatin C [eGFRcys] and estimated glomerular filtration rate based on creatinine [eGFRcr], respectively) is increasing. When eGFRcr and eGFRcys are discordant, it is not known which is more accurate, leading to uncertainty in clinical decisio

Research bricolage on far-right metapolitics: Superordinate intersectionality perspectives on digital identities

This article is a reaction to previous appeals to widen the conceptual remit of Critical Discourse Studies (CDS). It proposes research bricolage as means for critical engagement with conceptual constructs originating from adjacent social science disciplines. Borrowing such concepts as far-right metapolitics from political science, superordinate intersectionality from gender studies, and Web 2.0 so

"Överraskningsattacker: Sexdagarskriget - Jom Kippurkriget en jämförelse"

Abstract The Six-Day War of 1967 and the Yom Kippur War of 1973 are two of the most important military altercations of the Arab-Israeli conflict. Both wars were started by surprise attacks by either side. In 1967 Israel surprised the arab nations and in 1973 the arab nations surprised Israel. This essay is going to, both, analyse the deception and surprise performed in the wars separately and then

IMPLAUSIBLE DENIABILITY SOM INFORMATIONSSTRATEGI

I ett nytt och mer pluralistiskt medielandskap, med plattare strukturer, har en ny typ av informationsanvändning växt fram. Denna verkar genom att skapa osäkerhet och därigenom möjlighet till implausible deniability snarare än den plausible deniability som tidigare varit vanlig och intimt förknippad med covert action. På detta område har den ryska staten ansetts vara en föregångare men mindre är k

“I’m the guy they used to call Deep Throat” - En kvalitativ studie av medierapporteringen av visselblåsare i en amerikansk kontext

Den här studien undersöker huruvida medierapporteringen av visselblåsare påverkar vilket fokus media väljer att lägga i sin rapportering: på visselblåsaren eller den information som har läckts. Analysen genomfördes med en narrativ textanalys där totalt sex stycken artiklar om Mark Felt, personen bakom Watergate-visselblåsaren Deep Throat, och Chelsea Manning. Resultatet visar att det finns en skil

Performance Evaluation of Ground Heating and Cooling Systems - Long-term performance measurements of two case buildings

Geothermal energy is one of the oldest and most sustainable energy sources and has been used for thousands of years. The temperature of the ground at shallow depth is fairly constant, above the air temperature in winter and lower than the ambient temperature in summer. Shallow geothermal energy systems can thus be used to provide heating and cooling with or without heat pumps. This study aims to

Protecting positions of power and privileges : The Racial Glass Ceiling in the UK Civil Society Sector

As institutional racism and the underrepresentation of BAME have become world-wide central issues, the question of equal opportunities for upward mobility in the labour market and social mobility for this particular community are at the forefront, including the UK context. Evidence suggests that BAME have unequal access to opportunities for career progression in the workplace and that upward mobil
