Human Eye Visualization With an Attention Mechanism: Enhancing Flower Detection and Classification With Visual Attention and Photometric Principles Inspired by Human Vision

Engineering Reports, Volume 8, Issue 3, March 2026.
The graphical abstract illustrates a flower classification model relying on the human visual system. The model captures images, simulates visual attention and photometric perception, extracts features of shape and color, and classifies flowers by using an optimized neural network that enhances recognition accuracy by mimicking the human eye's focusing ...

Beyond the Highlands: Climate Drives Evolutionary Connections Between Ancient Neotropical Mountains and Lowland Biomes

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim The assembly of montane plant communities through time is underlain by historical and abiotic factors. However, the extent of evolutionary connectivity between ancient highland ecosystems and surrounding lowlands remains unclear. Here, we investigate the evolutionary connections between the campos rupestres, a hyperdiverse and fragmented ...

The Effects of Sevoflurane Versus Total Intravenous Anesthesia on Emergence Agitation After Interventional Neuroradiology: A Prospective Randomized Controlled Trial

Anesthesiology Research and Practice, Volume 2026, Issue 1, 2026.
Background Interventional neuroradiology (INR) is a minimally invasive procedure that is often performed under general anesthesia. A potential complication, emergence agitation (EA), can hinder immediate and accurate postoperative neurological assessments. Sevoflurane and propofol are common anesthetics used for these procedures.

Comparison of Scalp Block and Intravenous Esmolol for Hemodynamic Responses During Skull Pin Application in Elective Supratentorial Craniotomy

Anesthesiology Research and Practice, Volume 2026, Issue 1, 2026.
Background Skull pin application during craniotomy often causes significant hemodynamic responses that can be detrimental to patients with intracranial pathology. Both scalp block and intravenous esmolol are established methods for attenuating these responses, but their comparative efficacy remains unclear.
