From “Mirror Flower, Water Moon” to Multi‐Task Visual Prospective Representation Learning for Unmanned Aerial Vehicles Indoor Mapless Navigation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Vision‐based deep learning models have been widely adopted in autonomous agents, such as unmanned aerial vehicles (UAVs), particularly in reactive control policies that serve as a key component of navigation systems. These policies enable agents to respond instantaneously to dynamic environments without relying on pre‐existing maps.

Eigenfeature‐enhanced deep learning: advancing tree species classification in mixed conifer forests with lidar

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Workflow for tree species classification using lidar data. Steps include preprocessing (normalization, noise removal, CHM creation), tree segmentation, eigenfeature extraction, and 2D CNN training/validation. Blue, yellow, and red indicate training, validation, and testing image sets, respectively.

Photoprotective Effects of Two New Morin-Schiff Base Derivatives on UVB-Irradiated HaCaT Cells

open access: yesAntioxidants
Ultraviolet (UV) radiation harms the skin, causing oxidative damage, inflammation, and disruption of the skin’s barrier function. There is considerable interest in identifying new natural ingredients with antioxidant and anti-inflammatory properties to ...

Tourist sightings improve the precision of camera trap‐derived density estimates using spatial capture‐recapture models

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we combine tourist‐contributed images with camera trap‐based monitoring data to estimate leopard (Panthera pardus) population densities using multi‐session spatial capture–recapture models. We show that incorporating tourist observations improves precision and yields an overall density estimate of 7.02 leopards per 100 km2, while ...

Protective Potential of Morin in Ifosfamide-Induced Lung Toxicity: Modulation of Oxidative Stress, Inflammation and Apoptosis Parameters

open access: yesVeterinary Sciences and Practices
In this study, the protective effect of morin against lung toxicity induced by ifosfamide (IFO), a widely used drug in cancer treatment, was investigated. Thirty-five male Sprague Dawley rats were divided into five groups: Control, Morin (200 mg/kg), IFO

The Weil-\'etale fundamental group of a number field II

open access: yes, 2010
We define the fundamental group underlying to Lichtenbaum's Weil-\'etale cohomology for number rings. To this aim, we define the Weil-\'etale topos as a refinement of the Weil-\'etale sites introduced in \cite{Lichtenbaum}. We show that the (small) Weil-\

Gender Differences in Sitting Positions of College Students and an Explanation of These Differences [PDF]

open access: yes, 2010
This article explores the differences in the sitting positions of college men and women. After conducting unobtrusive observations of 83 students at the University of New Hampshire, we analyzed our data and found that there are differences in the way men
