Quadratic Quasinormal Mode Dependence on Linear Mode Parity.

Quasinormal modes (QNMs) uniquely describe the dominant piece of the gravitational-wave ringdown of postmerger black holes. While the linear QNM regime has been extensively studied, recent work has highlighted the importance of second-perturbative-order, quadratic QNMs (QQNMs) arising from the nonlinear coupling of linear QNMs. Previous attempts to quantify the magnitude of these QQNMs have shown discrepant results.

Violence and nicotine replacement therapy in a high dependency mental health unit.

Introduction: Nicotine withdrawal is associated with aggression on mental health wards. This study examined whether the introduction of an inhaled form of Nicotine Replacement Therapy (NRT) improved acceptability and reduced observed aggression on a high dependency mental health unit (HDU), at a tertiary level metropolitan hospital.

Method: This retrospective cohort study included tobacco smokers admitted to the HDU over two consecutive years, following a smoking ban at the hospital.

Voiding dysfunction after surgery for colorectal deep infiltrating endometriosis: an updated systematic review and meta-analysis.

To define the risk factors of post-operative voiding dysfunction according to the type of surgical procedure performed. A systematic review through PubMed, the Cochrane Library, and Web of Science databases was performed. The Medical Subject Headings terms aimed for English articles about colorectal endometriosis surgery and voiding dysfunction published until December 26, 2022 were used.

Impact of caesarean scar defects on the success of assisted human reproduction: the NICHE-ART prospective French cohort study protocol.

Background: The global increase in caesarean sections (CS), currently at 21.1% of all deliveries, has led to a rise in uterine scar defects, or 'niches', at the hysterotomy site. These niches, detectable in 13%-84% of cases via transvaginal ultrasound (TVS) and 42%-84% through sonohysterography (SHG), may contribute to gynaecological complications, including abnormal uterine bleeding, chronic pain and secondary infertility.
