Sensory losses or reductions are frequently attributed to relaxed selection. However, anuran species have lost tympanic middle ears many times, despite anurans' use of acoustic communication and the benefit of middle ears ...

The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on ...

The objective of this study is to analyze the possibility of blending conventional instruction with online instruction via a social networking website, Facebook, in EFL classrooms in order to motivate students and improve ...

This paper focuses on the generalized arc routing problem. This problem is stated on an undirected graph in which some clusters are defined as pairwise- disjoint connected subgraphs, and a route is sought that traverses ...

Most anurans possess a tympanic middle ear (TME) that transmits sound waves to the inner ear; however, numerous species lack some or all TME components. To understand the evolution of these structures, we undertook a ...

We present a 12,6700-yr limnological history of Lake Miski, a high-elevation lake in a wet section of the Peruvian Andes. While many shallow Andean lakes dried up during the mid-Holocene, loss-on-ignition, magnetic ...

Within the framework of density functional theory, a study of approximations to the enhancement factor of the non-interacting kinetic energy functional Ts[ρ] has been presented. For this purpose, the model of Liu and Parr ...

La canción bailable es poco apreciada por el conservacionismo caribeño a pesar de su eficacia comunicativa. Se estudiaron 1200 canciones afro-caribeñas anotando la frecuencia y el contexto en que mencionan elementos ...

This paper analyses the impact of two interventions on women's empowerment in Ecuador using an experimental design. Women's empowerment is operationalized by using two metrics: first, the participation of women in the ...

Species distribution models (SDMs) are widely used in ecology and conservation. Presence-only SDMs such as MaxEnt frequently use natural history collections (NHCs) as occurrence data, given their huge numbers and accessibility. ...
