The tonal webern: a physiognomy of early modernism by Wedler, S

“…Through close study of key works such as the symphonic tone poem <em>Im Sommerwind</em>, the ‘Segantini’ string quartet, and the <em>Passacaglia</em> for large orchestra op. 1 in light of recent developments in the theory and analysis of late nineteenth-century tonal music (sonata deformation theory, extended Schenkerian techniques, and neo-Riemannian transformations), each chapter illuminates a unique aspect of Webern’s early modernist imagination. …”

When do tripdoublet states fluoresce? A theoretical study of copper(II) porphyrin by Xingwen Wang, Chenyu Wu, Zikuan Wang, Zikuan Wang, Wenjian Liu

“…Intriguingly, we showed that the aforementioned tripdoublet state is only slightly above the lowest doublet excited state and lies only slightly higher than the lowest quartet state, which suggests that the tripdoublet of copper(II) porphyrin is long-lived enough to fluoresce due to a lack of efficient non-radiative relaxation pathways; an explanation for this unusual state ordering is given. …”

The Discharge Communication Study: research protocol for a mixed methods study to investigate and triangulate discharge communication experiences of patients, GPs, and hospital pro... by Katharine Weetman, Jeremy Dale, Emma Scott, Stephanie Schnurr

“…Participant viewpoints are collected through interviews, focus groups and surveys and will be “matched” to the discharge letter sample, so forming multiple-perspective “quartet” cases. These “quartets” allow direct comparisons between different discharge experiences within the same communicative event. …”

The effect of catalyst layer design on catalyst utilization in PEMFC studied via stochastic reconstruction method by Congfan Zhao, Shu Yuan, Xiaojing Cheng, Zhifeng Zheng, Jia Liu, Jiewei Yin, Shuiyun Shen, Xiaohui Yan, Junliang Zhang

“…Catalyst utilization is an important determinant of proton exchange membrane fuel cell performance, and increasing the catalyst utilization is one of the most critical approaches to reducing the catalyst loading in PEMFC. 4-phase stochastic reconstruction method based on the variable-resolution Quartet Structure Generation Set (QSGS) algorithm is utilized to elucidate the influence of different parameters of electrode preparation, including the porosity, the dispersion degree of carbon agglomerate, ionomer content, and carbon support size, on the catalyst utilization in the catalyst layer. …”

Ultrafast Jahn‐Teller Photoswitching in Cobalt Single‐Ion Magnets by Sophie E. Canton, Mykola Biednov, Mátyás Pápai, Frederico A. Lima, Tae‐Kyu Choi, Florian Otte, Yifeng Jiang, Paul Frankenberger, Martin Knoll, Peter Zalden, Wojciech Gawelda, Ahibur Rahaman, Klaus B. Møller, Christopher Milne, David J. Gosztola, Kaibo Zheng, Marius Retegan, Dmitry Khakhulin

“…The combined measurements and their analysis supported by density functional theory (DFT), time‐dependent‐DFT (TD‐DFT) and multireference quantum chemistry calculations reveal that the complex undergoes a spin‐state transition from a tetragonally elongated doublet state to a tetragonally compressed quartet state on the femtosecond timescale, i.e., it sustains ultrafast Jahn‐Teller (JT) photoswitching between two different spin multiplicities. …”

NMR detection and conformational dependence of two, three, and four-bond isotope shifts due to deuteration of backbone amides by Alexandrescu, Andrei T., Dregni, Aurelio J., Teschke, Carolyn M.

“…Neither parameter showed significant differences for hydrogen-bonded sites, or changes over a 25° temperature range, suggesting they are not sensitive to hydrogen bonding. Finally, the quartet that arises from the combination of 2∆C’(ND) and 3∆C’(ND) isotope shifts in H(CA)CO spectra was used to measure synchronized hydrogen exchange for the sequence neighbors A315-S316 in the protein CUS-3iD. …”

Spectroscopy and dynamics of metal clusters by Hamilton, S, Suzanne Hamilton

“…The rotational constants and band origins of several known states have been determined, and the observation of a new spin-forbidden transition has been used to connect the energies of the quartet and doublet manifolds of VO. A new 3 ²Π state was also observed and characterised.…”

Capture threshold of bipolar and unipolar pacing of left ventricle via coronary sinus branch: longitudinal study by Jakub Stritecky, Jakub Stritecky, Jan Kremlacek, Josef Hanus, Ludek Haman, Hana Stritecka, Jakub Simka, Petr Parizek

“…IntroductionThe aim of this paper is to first monitor the changes in the capture threshold of endovascularly placed leads for left ventricle pacing, second to compare the pacing configurations, and third to verify the effect of Steroid elution for endovascular leads.Sample and MethodThe study included 202 consecutive single centre patients implanted with the Quartet™ lead (St. Jude Medical). The capture threshold and related lead parameters were tested during implantation, on the day of the patient’s discharge, and 3, 9, and 15 months after implantation. …”

Study on regenerative exothermic process in ash containing DPF structure based on lattice Boltzmann method by Xiangdong Li, Chaofang Xue, Jiawang Geng, Xiaori Liu, Tiechen Zhang, Boxiong Shen

“…However, after a long period of operation, the DPF wall formed dense ash layer, which seriously affected the normal operation of the DPF. In this paper, Quartet Structure Generation Set is used to add the ash layer micro-structure, and the lattice Boltzmann method is used to explore the influence of ash layer in the ash containing DPF structure on its oxidation and regeneration process. …”
