Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Assessment of detection methods for the endangered Amargosa vole

California Fish and Wildlife Journal
Understanding which detection methods to use is important to endangered species research and management and often requires a balance between costs and benefits. We investigated the efficiency and costs of camera-trapping, live-trapping, and sign surveys (

Economical crowdsourcing for camera trap image classification [PDF]

Remote Sensing in Ecology and Conservation, 2018
AbstractCamera trapping is widely used to monitor mammalian wildlife but creates large image datasets that must be classified. In response, there is a trend towards crowdsourcing image classification. For high‐profile studies of charismatic faunas, many classifications can be obtained per image, enabling consensus assessments of the image contents. For

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response

Advanced Functional Materials, EarlyView.
This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...

Particle tracking stereomicroscopy in optical tweezers: control of trap shape [PDF]

, 2010
We present an optical system capable of generating stereoscopic images to track trapped particles in three dimensions. Two-dimensional particle tracking on each image yields three dimensional position information.

Using camera traps to study the elusive European Wildcat Felis silvestris silvestris Schreber, 1777 (Carnivora: Felidae) in central Germany: what makes a good camera trapping site?

Journal of Threatened Taxa, 2019
Camera traping is a widely used method to study the abundance and population density of elusive terrestrial animals.  To make full use of this method, it is necessary to obtain high photographic capture rates of the target species.

A comparison of density estimation methods for monitoring marked and unmarked animal populations

Ecosphere, 2022
Effective monitoring of wildlife populations forms the foundation of modern‐day conservation biology. Without reliable estimates of population size, it is not possible to determine population trends, a key requirement in determining species status under ...
