AI Article Synopsis
- Multi-sensor imaging systems that combine GNSS and DMC are crucial for accurate geo-referencing in long-range surveillance applications.
- Specific calibration and compensation techniques for DMC are necessary to ensure precise heading accuracy, which varies based on the operating environment.
- The study demonstrates that the swinging procedure is an effective method for DMC compensation, and experimental results confirm that integrating the DMC enhances the geo-referencing capabilities in surveillance systems.
Article Abstract
Multi-sensor imaging systems using the global navigation satellite system (GNSS) and digital magnetic compass (DMC) for geo-referencing have an important role and wide application in long-range surveillance systems. To achieve the required system heading accuracy, the specific magnetic compass calibration and compensation procedures, which highly depend on the application conditions, should be applied. The DMC compensation technique suitable for the operation environment is described and different technical solutions are studied. The application of the swinging procedure was shown as a good solution for DMC compensation in a given application. The selected DMC was built into a system to be experimentally evaluated, both under laboratory and field conditions. The implementation of the compensation procedure and magnetic sensor integration in systems is described. The heading accuracy measurement results show that DMC could be successfully integrated and used in long-range surveillance systems providing required geo-referencing data.

Context: Understanding the structural characteristics of coal at the molecular level is fundamental for its effective utilization. To explore the molecular structure characteristic, the long-flame coal from Daliuta (DLT), coking coal from Yaoqiao (YQ), and anthracite from Taixi (TX) were investigated using various techniques such as elemental analysis, Fourier transform infrared spectroscopy, solid-state C nuclear magnetic resonance spectroscopy, and X-ray photoelectron spectroscopy. Based on the structural parameters, the coal molecular model was constructed and optimized.

Objective: To assess the carbon footprint, accessibility, and diagnostic performance of an expedited 'One-Stop' prostate cancer (PCa) diagnostic pathway.
Materials And Methods: A total of 1083 consecutive patients undergoing magnetic resonance imaging (MRI) followed by transrectal ultrasound fusion-guided prostate biopsy (PBx) were identified from a prospective database. The patients were divided according to the diagnostic pathway: One-Stop, with MRI and same-day PBx (3 hours apart), or Standard, with MRI followed by a second visit for PBx.
Objectives: The objective of this study is to evaluate the diagnostic performance of perineal access cannulas tethered to a biplanar ultrasound probe in cognitive transperineal prostate biopsies of targets identified by multiparametric magnetic resonance imaging (mpMRI) by comparing the results of the PrecisionPoint (PP) Transperineal Access System with the double-freehand (DFH) technique.
Patients And Methods: All patients who underwent cognitive transperineal prostate biopsy of mpMRI targets using the PP or DFH technique between November 2020 and September 2023 were enrolled. All data related to mpMRI target biopsies were stratified by technique, visibility in transrectal ultrasound and analysed by comparing PP versus DFH.

Objective: The aim of this study was to assess the precision and safety of targeted microwave ablation (TMA) using organ-based tracking (OBT) fusion, in patients with intermediate risk prostate cancer.
Patients And Method: We conducted a prospective, multicentric trial. Eligible patients had a prostate-specific antigen (PSA) < 20 ng/mL, a magnetic resonance imaging (MRI)-visible index tumour of Gleason score 3 + 4, with largest axis ≤15 mm and distant of at least 5 mm from the rectum and apex.

Article Synopsis
- The study focused on evaluating the safety and effectiveness of psilocybin for patients with severe treatment-resistant depression (TRD), who had not benefited from at least five previous treatments.
- Conducted over 12 weeks at Sheppard Pratt Hospital, patients received a single 25 mg dose of synthetic psilocybin and underwent therapy sessions before and after dosing, assessing their depression levels mainly with the Montgomery-Åsberg Depression Rating Scale (MADRS).
- Results showed significant reductions in depressive symptoms at both 3 weeks and 12 weeks post-treatment, indicating psilocybin’s potential as a viable option for individuals with severe TRD, although those with comorbid PTSD experienced less improvement.
