Purpose: The SARS-CoV‑2 pandemic has affected the health and practice of otorhinolaryngologists (ORLs) for over 1 year. Follow-up data of a national survey with German ORLs were evaluated regarding differences between the two waves of the pandemic.
Methods: As in the initial survey, German ORLs were addressed via e‑mail through the German Society of ORL, Head and Neck Surgery and the German ENT Association. All ORLs afflicted with SARS-CoV‑2 were invited to participate in a web-based survey. General data on infections and concomitant parameters were evaluated.
Results: Since the start of the pandemic, 129 ORLs reported testing positive for SARS-CoV‑2 in Germany. The ORLs infected during the first wave had a relative risk (RR) of 4.07 (95% CI: 3.20; 5.19) of contracting SARS-CoV‑2. During the second wave, the RR decreased to 0.35 (95% CI: 0.28; 0.45). The availability of personal protective equipment (PPE) increased from the first to the second wave along with an increased perception of protection in the professional environment. The source of infection shifted from infections via medical staff during the first wave to patients and household exposure during the second wave. Regular medical practice was resumed by clinicians and general practitioners in the second wave. Nevertheless, a proportionally lower infection rate was observed compared with the German population as a whole.
Conclusion: The data reflect a unique long-term survey of ORLs during the pandemic. Differences in the source of infection were seen between the first and second wave, confirming the need for appropriate PPE for medical professionals working in high-risk environments. Further strategies to reduce the risk of infection include consistent testing for SARS-CoV‑2 in healthcare professionals, patients, and the general public as well as vaccination of high-risk medical groups.

We construct a non-chiral conformal field theory (CFT) on the torus that accommodates a second quantization of the elliptic Calogero-Sutherland (eCS) model. We show that the CFT operator that provides this second quantization defines, at the same time, a quantum version of a soliton equation called the non-chiral intermediate long-wave (ncILW) equation. We also show that this CFT operator is a second quantization of a generalized eCS model which can describe arbitrary numbers of four different kinds of particles; we propose that these particles can be identified with solitons of the quantum ncILW equation.

To assess the effectiveness of transcatheter aortic valve replacement (TAVR) on electrocardiographic remodeling in patients with severe aortic stenosis (AS), and identify its influencing factors. A cohort study was conducted on patients with a confirmed diagnosis of severe AS who successfully underwent TAVR at the Second Affiliated Hospital of Dalian Medical University between June 2018 and March 2023. Data, including standard 15-lead electrocardiograms and echocardiograms, were collected before the operation, 1 week after the operation, and 3 months after the operation.

Hanbury-Brown and Twiss (HBT) effect is the foundation for stellar intensity interferometry. However, it is a phase insensitive two-photon interference effect. Here we extend the HBT interferometer by mixing intensity-matched reference fields with the input fields before intensity correlation measurement.

Background: While social support is associated with better cognitive health among cancer-free individuals, this relationship is understudied among cancer survivors. We investigated whether overall social support before and after a cancer diagnosis is related to post-diagnosis memory ageing, overall and by sex/gender.
Methods: Data were from 2044 cancer survivors in the US Health and Retirement Study (HRS; n=1395) and English Longitudinal Study of Ageing (ELSA; n=649) from 2006 to 2018.

This study delves into the feasibility of leveraging quasi-static component (QSC) generation during primary Lamb wave propagation to discern subtle alterations in the interfacial properties of a two-layered plate. Unlike the second-harmonic generation of Lamb waves, QSC generation doesn't necessitate precise phase-velocity matching but rather requires an approximate matching of group velocities to ensure the emergence of cumulative growth effects. This unique characteristic empowers the QSC-based nonlinear ultrasonic method to effectively surmount the limitations associated with inherent dispersion and multimode traits of Lamb wave propagation.
