Consistent and scalable monitoring of birds and habitats along a coffee production intensity gradient

Remote Sensing in Ecology and Conservation, EarlyView.
Birds are commonly used as indicators of the effect of habitat degradation on biodiversity in the tropics. However, monitoring birds and their habitat in a way that is consistent, reliable and scalable remains an important challenge. Here, we examine whether bioacoustics and remote sensing can be used to efficiently monitor avian biodiversity and ...

Traffic Noise Absorption and Propagation in A Three-Dimensional Spatial Environment

Geoplanning: Journal of Geomatics and Planning
The impact of noise barriers on noise propagation is vital for traffic noise calculations and visualizations. Noise barriers create a major noise reduction. Green belts are the most common type of noise barrier to mitigate road traffic noise.

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

Small, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

A multi‐dimensional index of evaluating systems thinking skills from textual data

Systems Research and Behavioral Science, EarlyView.
Abstract Systems thinking (ST) includes a set of critical skills and approaches for addressing today's complex societal problems. Therefore, it has been introduced into the curricula of many educational programmes around the world. Despite all the attention to ST, there is less consensus when it comes to evaluating and assessing ST skills. Particularly,

ROLLING BEARING FAULT DIAGNOSIS BASED ON ADAPTIVE FEATURE SELECTION k-SUB CONVEX HULL

Jixie qiangdu
Feature selection and classifier design are often studied separately in rolling bearing fault diagnosis, so it is difficult to obtain satisfactory classification accuracy.

Home range and core area characteristics of urban and rural coyotes and red foxes in southern Wisconsin

Wildlife Biology, EarlyView.
Second‐order habitat selection is influenced by a variety of factors, including individual‐ and species‐specific traits and resource requirements, as well as landscape characteristics. By comparing home range characteristics across individuals, species, and landscapes, we can draw conclusions regarding whether and how different factors influence home ...
