Interspecific interactions among species of the same guild play a critical role in shaping their realized niches, and their understanding may disclose mechanisms of coexistence. Investigating interactions among apex predators is of ecological and management interest, especially in human-dominated landscapes where type and intensity of their interspecific competition may be affected by human interference. During 2005-2010, we investigated, by means of GPS-telemetry, interactions between brown bears ( = 19) and wolves ( = 7) in a long-established national park in the central Apennines, Italy, where bears and wolves have always coexisted close to humans.

Article Synopsis
  • - Deep anterior lamellar keratoplasty (DALK) is a surgical technique for treating corneal disorders without affecting the endothelium, which helps prevent rejection and late graft failure compared to traditional penetrating keratoplasty (PK).
  • - The introduction of the big-bubble technique (BBT) improved the efficiency and consistency of DALK by using air to separate corneal layers, resulting in high-quality grafts comparable to PK.
  • - Understanding the anatomy behind BB formation, including the significance of Dua's layer, is essential for successful DALK procedures; ongoing improvements in BBT are increasing its use in corneal transplants with healthy endothelium.

PFASs are a variety of ecologically persistent compounds of anthropogenic origin loosely included in many industrial products. In these, the carbon chain can be fully (perfluoroalkyl substances) or partially (polyfluoroalkyl substances) fluorinated. Their ubiquitous presence in many environmental compartments over the years and their long-lasting nature have given rise to concerns about the possible adverse effects of PFASs on ecosystems and human health.

Since the new guidelines for endometrial cancer risk classification have been published, many reviews have proposed a critical re-evaluation. In this review, we look back to how the molecular classification system was built and its evolution in time to highlight the major flaws, particularly the biases stemming from the inherent limitations of the cohorts involved in the discoveries. A significant drawback in some cohorts is the inclusion criteria, as well as the retrospective nature and the notably sparse numbers, especially in the (nonsynonymous mutation in EDM domain of POLE) risk groups, all of which impact the reliability of outcomes.

This paper demonstrates the design steps of a slot-loaded Vivaldi antenna for biomedical microwave imaging applications, showing the influence of the design parameters on the antenna's dimensions and performances. Several antenna miniaturization techniques were taken into consideration during the design: reduction in the electromagnetic wavelength by using a high-permittivity substrate material (relative permittivity ϵr=10.2), the placement of the antenna inside a coupling medium (ϵr=23), and the elongation of the current path by etching slots on each side of the radiator to reduce the antenna's lowest resonant frequency without increasing its physical dimensions.
