Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

System for analyzing data from camera traps based on a two-stage neural network approach for operational remote monitoring [PDF]

open access: yesITM Web of Conferences
Camera traps are a widely used tool for monitoring wildlife with minimal human intervention. Their number can amount to several hundred, and the accumulated volume can reach several terabytes.

Density Estimation of Unmarked Populations Using Camera Traps in Heterogeneous Space

open access: yesWildlife Society Bulletin, 2020
Camera traps are commonly used to monitor animal populations, but statistical estimators of density from camera‐trap data for species that cannot be individually identified are still in development, and few models take space use into account.

The experience of low-resource fauna research by using camera traps

open access: yesTheriologia Ukrainica, 2021
The tasks of managing animal populations (conservation, exploitation, and control) require reliable initial information for their implementation. This information includes a number of parameters: spatial distribution, annual and daily cycles of activity,

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Precision preparation of strings of trapped neutral atoms [PDF]

open access: yes, 2006
We have recently demonstrated the creation of regular strings of neutral caesium atoms in a standing wave optical dipole trap using optical tweezers [Y. Miroshnychenko et al., Nature, in press (2006)].

Economical crowdsourcing for camera trap image classification [PDF]

open access: yesRemote 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

A Surface‐engineered Microfluidic Device for Antibody‐Mediated Negative Selection of High‐Quality Sperm for Assisted Reproduction

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a microfluidic device with a functionalized surface utilizing a polyoxazoline coating and covalently immobilized gold nanoparticles and anti‐phosphatidylserine antibody. The device efficiently eliminates pre‐apoptotic and apoptotic spermatozoa and yields sperm with substantially improved quality and low DNA damage, offering a simple ...

Automating the Surveillance of Mosquito Vectors from Trapped Specimens Using Computer Vision Techniques

open access: yes, 2020
Among all animals, mosquitoes are responsible for the most deaths worldwide. Interestingly, not all types of mosquitoes spread diseases, but rather, a select few alone are competent enough to do so. In the case of any disease outbreak, an important first
