Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Automotive Start-Stop Engine Based on Face Recognition System [PDF]

open access: yesE3S Web of Conferences, 2019
There are so many security devices such as code pin, dual control procedures, and ID card. However, those devices have the potential to be lost, stolen or duplicated by someone. Due to that reason, the authentication for driver by using their face is one

Video tracking of dairy cows for assessing mobility scores [PDF]

open access: yes, 2013
Lameness afflicts a large proportion of dairy herds, but could be considerably reduced by automated monitoring by CCTV. Key to this is reliable, robust detection and tracking of individual cows in crowded video sequences.

Robust Facial Recognition Using Unified Optimised Feature Fusion and Selection of Handcrafted and Deep Learning Features

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
This study presents a robust facial recognition framework based on a unified optimised feature vector that fuses handcrafted descriptors and deep learning embeddings. Using binary grey wolf optimisation for feature selection, the approach reduces redundancy while preserving discriminative power.

Breeding and foraging habitat are important in determining foraging ranges of sympatric generalist species

open access: yesIbis, Volume 168, Issue 1, Page 259-292, January 2026.
How far animals travel to gather food for offspring or themselves is a central component of ecology. Among birds, the ‘foraging range’ (straight‐line distance between a central place and a destination) is used to assess potential interactions with anthropogenic stressors such as wind farms.
