Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se 2 Solar Cells for Tandem Applications

ABSTRACT Tandem solar cells can better harness the energy of the solar spectrum. Chalcopyrite solar cells have drawn attention, being the only highly efficient devices with a bandgap around 1.0 eV, suitable for bottom cells. In the quest for better efficiencies, we conduct a comp...

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

ABSTRACT Pyroelectric materials are attractive for converting heat into electricity, yet the best performance is obtained with lead‐containing ceramics, remaining a major environmental concern. Here, we address this problem by developing lead‐free barium strontium titanate multil...

Integrative Multi‐Omics Analysis Reveals Convergent Epigenome and Transcriptome Changes in Parkinson's Disease

BACKGROUND: The mechanisms that predispose dopaminergic neurons (DAN) to degeneration in Parkinson's disease (PD) are incompletely understood. OBJECTIVE: To perform an integrative multi-omics reanalysis of single-cell transcriptomic and epigenomic data to identify convergent alte...

The Intergenerational Correlation of Subjective Well Being

There are many estimates of the intergenerational transmission of income and education, even though these may be considered as only partial measures of individual welfare. We here analyze long-running UK panel data and directly consider the intergenerational transmission of two w...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...

Theory Choice in Epistemic Networks: Five ways to avoid premature convergence

Abstract In this article, we study difficult theory-choice situations, where division of cognitive labor is needed. Network epistemology models suggest that reducing connectivity is needed to prevent premature convergence on bad theories. We compare how network density, community...

TrajectoryTest: A Trajectory-Specific Test Input Prioritization Technique and Empirical Evaluation

Trajectory prediction models have become increasingly vital in various safety-critical domains, such as healthcare, maritime surveillance, and intelligent transportation systems. These applications utilize machine learning models to predict the operational state of a moving agent...

pyMSscreen: an interactive interface for automated quality control and prescreening in mass spectrometry workflows

Reliable quality control of mass spectrometry data remains a major bottleneck in target, suspect and non-target screening workflows. In non-target analysis, thousands of features can be extracted through automated peak picking, many of which require manual verification to exclude...

Converging pathomechanisms link SARS-CoV-2 infection with major neurodegenerative diseases

Neurological complications are among typical clinical manifestations, both during the acute phase of SARS-CoV-2 infection and long-term post-acute COVID-19 sequelae, i.e., Long COVID. A growing body of evidence connects SARS-CoV-2 infection to systemic inflammation, peripheral im...

SoK: Cryptographic Key Recovery for Cryptoasset Custody and Financial Technologies

This record contains the full version of the paper accepted for publication at the International Conference on Advances in Financial Technologies (AFT 2026). It includes the complete 77-system master matrix and the seven-stage recovery walkthroughs that are not included in the pr...
