Survey and evaluation of classical guitar soundboard design methods with finite element analysis.

Designing the soundboards of guitars based on an acoustical and structural approach would ideally allow for the realization of instruments with reproducible acoustical properties and structural stability. This task is challenging because wood, the most common material used for this purpose, is a natural material with variable properties and building instruments using strict geometrical tolerances alone does not ensure reproducible results. Several approaches have been developed so far, some based on tradition and, more recently, on measurement of material properties and computer optimization.

Factors associated with the presence and abundance of Aedes albopictus and Aedes aegypti (Diptera: Culicidae): Perspectives from larval habitat-scale and neighbourhood-scale analyses in the Argentine subtropics.

Aedes albopictus (Skuse) and Aedes aegypti L. (Diptera: Culicidae) are invasive species known for their notable expansion capacity, which makes them relevant in the context of public health due to their role as vectors. In Argentina, these species coexist in a limited subtropical area in Northeastern part of the country.

The Hunga Tonga-Hunga Ha'apai volcanic barometric pressure pulse and meteotsunami travel recorded in several Antarctic stations.

The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered a meteotsunami and barometric pressure pulse that rippled through the atmosphere and oceans all around the world. The nature of the volcanic event and its global impacts on the oceans, atmosphere, lithosphere and the cryosphere are a matter of debate. Here we present a first overview of the time travel of the sound atmospheric pressure wave through the Antarctic continent based on in situ measurements, which represented a unique event observed through the polar ice sheet during the instrumental meteorological era.

The Re-Emergence of Neuroinvasive Flaviviruses in Croatia During the 2022 Transmission Season.

(Re-)emerging arboviruses, such as tick-borne encephalitis virus (TBEV), West Nile virus (WNV), and Usutu virus (USUV), are continuously increasing in incidence. We analyzed the epidemiological characteristics of flavivirus infections in humans, sentinel animals, and mosquitoes detected in the 2022 transmission season in Croatia. From April to November 2022, 110 hospitalized patients with neuroinvasive diseases (NID) were tested for the presence of arboviruses.

Less invasive surfactant administration versus intubation-surfactant-extubation in preterm infants: a retrospective study.

Aim: To compare the need for intubation and mechanical ventilation after surfactant delivery between less invasive surfactant administration (LISA)-treated and intubation-surfactant-extubation (IN-SURE)-treated premature infants with respiratory distress syndrome (RDS).

Methods: Retrospective registry-based cohort study enrolled 36 newborns admitted to the Neonatal Intensive Care Unit of the "Santa Maria" Hospital of Terni between 2016 and 2023. As a primary outcome, the need for intubation and mechanical ventilation within 72 hours of life was followed, and major neonatal morbidities and death before discharge as the secondary outcome.
