Giant dimeric acceptors (GDAs), a sub-type of acceptor materials for organic solar cells (OSCs), have garnered much attention due to the synergistic advantages of their monomeric and polymeric acceptors, forming a well-defined molecular structure with a giant molecular weight for high efficiency and stability. In this study, for the first time, two new GDAs, DYF-V and DY2F-V are designed and synthesized for OSC operation, by connecting one vinylene linker with the mono-/di-fluorinated end group on two Y-series monomers, respectively. After fluorination, both DYF-V and DY2F-V exhibit bathochromic absorption and denser packing modes due to the stronger intramolecular charge transfer effect and torsion-free backbones.

Methods: This retrospective cohort study analyzed the Nationwide Readmission Database from 2018 to 2020 to evaluate hospitalizations within 30 days preceding the current hospitalization for STEMI in order to determine how often this occurs and what are the causes and factors associated with the recent admission.
Results: There were 1,355,765 hospital admissions with a diagnosis of STEMI and 54,545 (4.
Background: There are no studies investigating missed opportunities for earlier diagnosis in newly/recently detected Type 2 Diabetes Mellitus and Non-alcoholic Fatty Liver Disease in the region of Bihar, India.
Methods: This study is a single-center cross-sectional study undertaken at the Research Centre for Diabetes Hypertension and Obesity, Samastipur, Bihar, India. The study collected data from newly/recently diagnosed persons with T2DM.
Background: We aimed to identify the central lifestyle, the most impactful among lifestyle factor clusters; the central health outcome, the most impactful among health outcome clusters; and the bridge lifestyle, the most strongly connected to health outcome clusters, across 29 countries to optimise resource allocation for local holistic health improvements.
Methods: From July 2020 to August 2021, we surveyed 16 461 adults across 29 countries who self-reported changes in 18 lifestyle factors and 13 health outcomes due to the pandemic. Three networks were generated by network analysis for each country: lifestyle, health outcome, and bridge networks.
