Here, we measured 147 immune-related proteins during acute COVID-19 to investigate these questions. Methods We measured circulating protein abundances using the SOMAscan nucleic acid aptamer panel in two large independent hospital-based COVID-19 cohorts in Canada...

Mid-infrared Nb₄N₃-based superconducting nanowire single photon detectors for wavelengths up to 10 μm

Yiming Pan, Hui Zhou, XINGYU ZHANG, Huiqin Yu, Lu Zhang, Mengting Si, Hao Li, Lixing YOU & Zhen Wang
Mid-infrared (MIR) single-photon detection is emerging as an important technology for various applications. Superconducting nanowire single photon detectors (SNSPDs) fabricated with superconducting films with energy gaps of a few meV are natural broadband single-photon detectors. Recently, extending SNSPDs’ operation wavelengths into the MIR region is highly attractive. γ-Nb₄N₃ has a reduced N content and lower energy gap than the commonly used δ-NbN, making SNSPDs based on γ-Nb₄N₃ film more sensitive to low energy photons. We...

Educating physicians on strong opioids by descriptive versus simulated-experience formats: a randomized controlled trial

Odette Wegwarth, Claudia Spies, Wolf-Dieter Ludwig, Norbert Donner-Banzhoff, Günther Jonitz & Ralph Hertwig
Abstract Background Long-term prescriptions of strong opioids for chronic noncancer pain—which are not supported by scientific evidence—suggest miscalibrated risk perceptions among those who prescribe, dispense, and take opioids. Because risk perceptions and behaviors can differ depending on whether people learn about risks through description or experience, we investigated the effects of descriptive versus simulated-experience educative formats on physicians’ risk perceptions of strong opioids and their prescription behavior for managing chronic noncancer pain. Methods Three hundred...

Unambiguous spectral characterization on triplet energy transfer from quantum dots mediated by hole transfer competing with other carrier dynamics

Lei Wang, Gaoyuan Yang, Boyu Zhang, Xin Zhang, Dezheng Liu, Ying Liang & Guijie Liang
Triplet generation by QDs-sensitized molecules emerges great potential in many applications. However, the mechanism of triplet energy transfer (TET) is still fuzzy especially due to complicated energy level alignment of QDs and molecules or trap states in QDs. Here, CdSe QDs and 5-tetracene carboxylic acid (TCA) molecules are selected as the triplet donor and acceptor, respectively, to form a TET system. By tuning the band gap of CdSe, the CdSe-TCA complex is exactly designed to...

MEDICC2: whole-genome doubling aware copy-number phylogenies for cancer evolution

Tom L. Kaufmann, Marina Petkovic, Thomas B. K. Watkins, Emma C. Colliver, Sofya Laskina, Nisha Thapa, Darlan C. Minussi, Nicholas Navin, Charles Swanton, Peter Van Loo, Kerstin Haase, Maxime Tarabichi & Roland F. Schwarz
Abstract Aneuploidy, chromosomal instability, somatic copy-number alterations, and whole-genome doubling (WGD) play key roles in cancer evolution and provide information for the complex task of phylogenetic inference. We present MEDICC2, a method for inferring evolutionary trees and WGD using haplotype-specific somatic copy-number alterations from single-cell or bulk data. MEDICC2 eschews simplifications such as the infinite sites assumption, allowing multiple mutations and parallel evolution, and does not treat adjacent loci as independent, allowing overlapping copy-number events....
