Periodontitis and its association with left ventricular geometry and function: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background This study investigated the cross‐sectional association between periodontal status and left ventricular (LV) geometry and function, an early and prognostically relevant marker of cardiovascular disease. Methods Data were drawn from two population‐based cohorts in the Study of Health in Pomerania (SHIP): SHIP‐START‐2 (N = 2333) and ...

Wheat Sowing Practices in No‐Tillage Systems Modify the Microrelief and Hydrosedimentological Attributes: RPAS‐Based Photogrammetry

Land Degradation &Development, EarlyView.
ABSTRACT The microtopographic characteristics of terrain are modified by soil management and conservation practices, affecting water infiltration, storage, runoff generation, and sediment transport. However, assessing soil microtopography at representative spatial scales remains challenging and time‐consuming.

Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

Wildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

High Voltage, EarlyView.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...
