Nighttime lights (NTL) are the procurement of remotely sensed artificial illumination from the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite. NTL provides a unique perspective on anthropogenic activity by characterizing spatial and temporal patterns related to economic trends and human development. In this study, we assess the ability of NTL to characterize trends associated with industrial lumber production in British Columbia, Canada. We establish the presence of a logarithmic relationship between NTL and lumber mill production capacity (R2 = 0.69-0.82). The ability of NTL to temporally identify mill closures is then demonstrated by differentiating pairs of active and closed mills. We also identify Granger causality and co-integration between NTL and monthly lumber production, highlighting the predictive capability of NTL to forecast production. We then utilize this relationship to build linear regression models that utilize NTL data to estimate monthly (R2 = 0.33), quarterly (R2 = 0.58), and annual (R2 = 0.90) lumber production without reported data.

The transition of Negative Pressure Wound Therapy (NPWT) from hospitals to community care is a significant advancement in patient care, driven by increased practitioner competence and technological improvements. Modern, mobile NPWT systems, equipped with smaller pumps, have expanded treatment options and reduced hospital stays. However, discharging patients with NPWT systems introduces some logistical challenges, including staff training, supply management and effective communication between hospital staff and community teams.

Article Synopsis
- - Solid wood is a highly valued material for construction and furniture, but defects like knots and cracks can weaken its properties and make it less suitable for certain uses.
- - The study presents BDCS-YOLO, an AI-based sawing strategy that uses dual-sided imaging to improve timber processing automation, achieving a high detection precision of 0.94 on a dataset of 450 images.
- - This new method not only improves the accuracy of defect detection but also increases the volume yield of sawn timber by 12.3%, enhancing the efficiency of solid wood resource utilization in the lumber industry.

The main concern that this study attempts to address is the reason that the local people sustainably conserve church forests while aggressively exploiting biodiversity in common forests, shrublands, and grasslands. The study assesses the local perspective on the links between flora biodiversity and ecosystem services across a range of management options in the typical watershed of the Northwest highlands of Ethiopia. A mixed study design that included questionnaires, remote sensing, and hermeneutics was used because of the multidisciplinary character of the research.
