Wildlife protection through UAV surveillance with thermal infrared imaging and deep learning

Raja Vavekanand, Abdullah Ayub Khan — Fri, 06 Feb 2026 00:00:00 -0600

The purpose of this study is to develop a real-time UAV-based wildlife surveillance system capable of detecting camouflaged and nocturnal animals using thermal infrared imaging. The study addresses the limitations of RGB and night-vision cameras, which perform poorly in low-light and vegetation-dense environments, by introducing a unified deep learning approach tailored for TIR data. The methodology uses the BIRDSAI aerial thermal dataset and adapts the YOLOR architecture through multi-channel TIR augmentation and adaptive thresholding. The model was evaluated against YOLOv5 and CenterNet2 under identical configurations, with performance assessed through mAP, inference speed, and precision-recall analysis. Experiments were performed on both synthetic and real TIR sequences with extensive augmentation to enhance robustness. The findings show that the proposed YOLOR-based framework achieves a mAP of 38.2% and real-time processing at 73.6 FPS, outperforming YOLOv5 and CenterNet2 in detecting small, low-contrast, and camouflaged animals. Adaptive thresholding improved precision by 4%, particularly for species with overlapping heat signatures. Class-merging and multi-channel enhancement further improved detection stability under limited data conditions. The practical implications indicate that UAV-mounted TIR imaging combined with unified deep learning models offers an efficient solution for nocturnal wildlife protection, anti-poaching operations, and remote habitat monitoring. The system’s real-time capability supports large-scale conservation applications in environments where traditional visual-spectrum methods fail.

Emotional burnout in psychology students and its correction using cognitive-behavioral therapy

Tue, 10 Feb 2026 00:00:00 -0600

Emotional burnout among psychology students has specific characteristics. 1) Background: This condition results from the nature of the profession, which involves constant interaction with people, requiring sociability, empathy, and a strong professional identity. There are also particular features of emotional burnout in junior and senior psychology students. The differences in burnout between students at various academic levels have not been sufficiently studied. Additionally, methods for preventing mental health issues in students using cognitive-behavioral therapy have not been extensively researched. This study aims to examine the specific aspects of emotional burnout in junior and senior students and to correct their mental state through cognitive-behavioral therapy. 2) Methods: The research employed a pedagogical experiment, Spearman correlation analysis, Holland’s Vocational Interest Test, cognitive-behavioral therapy, Rational Emotive Behavioral Therapy (REBT), Cognitive Behavioral Art Therapy (CBAT), and cognitive therapy, which focuses on the connection between thoughts, feelings, and behaviors. 3) Results: The study found that emotional burnout in junior students is primarily associated with academic reasons, whereas in senior students, it relates to professional identity and competence in psychological practice. 4) Conclusion: The novelty of this research lies in the comparative analysis of the phases of emotional burnout among psychology students, identifying the causes of their mental states, and applying the latest cognitive-behavioral therapy methods.

Policies and strategies for the prevention and control of anemia and malnutrition in children and pregnant women: A systematic review

Tue, 10 Feb 2026 00:00:00 -0600

Malnutrition and anemia among children and pregnant women remain significant global public health challenges, particularly in low- and middle-income countries. These conditions hinder physical growth and cognitive development in children and compromise maternal health, thereby reinforcing cycles of poverty, disease, and premature mortality. Addressing these issues requires effective, sustainable, and context-sensitive responses. This study aims to systematically organize and examine policies and intervention strategies designed to prevent and control anemia and malnutrition in children under five and pregnant women. A systematic review was conducted using databases such as Scopus, EBSCO, Web of Science, and Taylor & Francis, covering publications from 2000 to 2023. The review adhered to PRISMA guidelines and applied the Joanna Briggs Institute quality appraisal standards. From an initial pool of 554 records, 28 studies met the inclusion criteria and were analyzed. Most of the included studies employed quantitative research designs, while fewer utilized qualitative or mixed-method approaches. Common interventions identified include iron and folic acid supplementation, deworming, food fortification, nutrition education, dietary diversification, and behavior change communication. Iron and folic acid supplementation consistently demonstrated effectiveness, especially when combined with educational components. However, several challenges persist, including low adherence to supplementation, socioeconomic and cultural barriers, limited resources, weaknesses in implementation, and regional differences in intervention effectiveness.

Development of ZE41 Mg–Nano-CDHA composites for biodegradable implant applications

Tue, 10 Feb 2026 00:00:00 -0600

In this current work, nanocrystalline calcium-deficient hydroxyapatite (CDHA) was synthetically produced using calcium hydroxide and diammonium phosphate through a wet chemical synthesis route. X-ray diffraction (XRD) analysis and electron microscopy demonstrated the nano-level (~47 nm) of the produced CDHA. Then, the nano-CDHA was reinforced into ZE41 Mg alloy by friction stir processing (FSP) aimed at manufacturing degradable bone implants. Microstructures clearly demonstrated the development of a fine-grained structure (7.4 ± 6.9 µm) in addition to incorporating nano-CDHA into ZE41 Mg alloy. FSP resulted in decreased intermetallic phases, which suggests increased solubility of zinc into magnesium due to FSP. XRD analysis of the composite confirms the development of a basal-dominated texture in the composite. From the potentiodynamic polarization studies, corrosion performance was assessed using simulated body fluid (SBF). The composite exhibited noble behavior by demonstrating a lower corrosion current density (-1.23 ± 0.8 × 10^-4 A/cm²) compared with ZE41 alloy (-4.75 ± 1.1 × 10^-4 A/cm²). Lower weight loss was observed for the composite after 72 hours of immersion in SBF, indicating improved degradation resistance due to the incorporated nano-CDAH and grain refinement. The lower corrosion rate measured for the composite (11.4 ± 2.1 mm/year) is 40% lower compared with ZE41 alloy (19.3 ± 1.8 mm/year) based on weight loss data. The results demonstrate the feasibility of FSP to develop ZE41-nano-CDHA composite with better corrosion control.
