AI Article Synopsis

  • Researchers have explored parametric instabilities as a limiting factor in high-power gravitational wave detectors for a long time.
  • This study reports the first observation of these instabilities in a large-scale (kilometer-scale) interferometer.
  • The authors detail how they identified this issue and successfully mitigated it, allowing for further advancements in gravitational wave detection.

Article Abstract

Parametric instabilities have long been studied as a potentially limiting effect in high-power interferometric gravitational wave detectors. Until now, however, these instabilities have never been observed in a kilometer-scale interferometer. In this Letter, we describe the first observation of parametric instability in a gravitational wave detector, and the means by which it has been removed as a barrier to progress.

Background: This study aims to report and analyze disease-specific patient-reported outcome measure (PROM) effect size (ES) variations, in patients undergoing major arthroplasty surgery.

Material And Methods: All institution-based data of primary knee, hip, or shoulder arthroplasty patients at Turku University hospital (Finland) between January 2020 -December 2022 were collected, and treatment outcome assessed as a PROM difference between baseline and one-year follow-up. PROM ES were calculated for each patient and patient group separately, and patients with ES >0.

Anterior Cruciate Ligament Reconstruction with Internal Brace Augmentation Results in Fewer Reruptures Compared to Reconstruction without Augmentation.

Rev Bras Ortop (Sao Paulo)

December 2024

Departamento de Ortopedia e Traumatologia, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brasil.

 To compare the clinical outcomes of anterior cruciate ligament (ACL) reconstruction using autografts with and without internal brace augmentation.  Data from patients who underwent ACL reconstruction with hamstring and quadriceps tendon autografts, with a minimum follow-up of one year, with or without internal brace augmentation were collected prospectively analyzed retrospectively. The Lysholm and Tegner functional scores were collected before and after surgery, as well as data on postoperative complications.

Purpose: Although 18 F-FDG-PET/CT is helpful in defining many types of cancer, localized prostate cancer should not be treated with this technique. This study describes the use of multi-parametric MRI (mpMRI) to characterize incidental 18 F-FDG uptake in the prostate.

Methods And Materials: While 18 F-FDG-PET/CT is useful for characterizing a variety of cancers, it is not advised for prostate cancer that is localized.

TransformerLSR: Attentive joint model of longitudinal data, survival, and recurrent events with concurrent latent structure.

Artif Intell Med

December 2024

Department of Applied Mathematics and Statistics, Johns Hopkins University, 3100 Wyman Park Dr, Baltimore, 21211, MD, USA; Division of Biostatistics and Bioinformatics, School of Medicine, Johns Hopkins University, 733 N Broadway, Baltimore, 21205, MD, USA. Electronic address:

In applications such as biomedical studies, epidemiology, and social sciences, recurrent events often co-occur with longitudinal measurements and a terminal event, such as death. Therefore, jointly modeling longitudinal measurements, recurrent events, and survival data while accounting for their dependencies is critical. While joint models for the three components exist in statistical literature, many of these approaches are limited by heavy parametric assumptions and scalability issues.

Article Synopsis
  • A study was conducted to evaluate the effects of malaria infection during the first trimester of pregnancy on adverse outcomes for mothers and babies in Kenya, Zambia, and the Democratic Republic of the Congo.
  • Using rigorous testing methods, researchers found specific risks such as higher rates of preterm birth and anemia later in pregnancy among affected women.
  • The findings suggest that first-trimester malaria is linked to increased prevalence of anemia and highlight the need for more research on its impact on other pregnancy complications like preterm birth and low birth weight.
