Summary: This paper explores the use of single-particle tracking and trajectory analysis to provide intracellular context for diamond magnetometry measurements. The findings show that this method accurately describes the movement of FNDs in different environments and deduces their intracellular localization in live cells.

Summary: This paper proposes a learning-based system and a hidden Markov model to assess hazardous places of a contagious disease and predict the probability of individuals' infection. By tracking the trajectories of individuals in an environment, the system accurately assesses hazardous places and determines the infection possibility with high probability, as demonstrated by simulation results. The proposed approaches can be applied to contagious diseases by tailoring them to the influential features of the disease.

Summary: This study describes the use of solid magnetic core phospholipidic structures (SMLs) as an MRI-trackable surrogate to aid in the clinical development of nano-liposomal formulations for cancer chemotherapy delivery. SMLs exhibited similar tumor deposition to nano-liposomal counterparts and superior capabilities compared to other clinically-approved iron oxide nano-formulations. The findings suggest that SMLs have high clinical translational potential for predicting and optimizing tumor deposition of nanoparticulate chemotherapy carriers.

Summary: A wearable intra-oral jaw position registration method is proposed, which addresses the two main issues of the method. The method compensates for background magnetic fields using two adjacent magnetometers, and includes jaw rotational angles in position calculations using trigonometric equations. Validation experiments showed a 37% decrease in error for the method.

Summary: Passive magnetic localization is a method that determines the position and orientation of objects with embedded magnets using an optimization algorithm. By detecting the magnetic field around the object and minimizing the difference between measured and calculated magnetic fields, the method aims to accurately locate objects.

Summary: The typical problem in small Unmanned Aerial Systems (sUAS) magnetic surveys is heading error caused by undesired aircraft magnetic signals, which can be addressed by suspending magnetometers on long tethers or fixing them on the aircraft and using magnetic compensation from calibration flights in low-magnetic-gradient areas. The open-source software presented in this study processes data and computes compensations for scalar and vector magnetometer systems, with the highest accuracy achieved by fixing the magnetometer below the sUAS onto a self-built carbon-fiber frame.

Summary: The dynamics model of the UUV system is complex and nonlinear. To improve its trajectory tracking control, a method based on nonlinear model predictive control and improved gray wolf optimization is proposed. Through simulation, the effectiveness and reliability of the proposed method are demonstrated. It outperforms traditional optimization algorithms in UUV trajectory tracking control.

Summary: Cell therapy has been widely used in treating diseases, but the migration, differentiation, and proliferation of living cells must be strictly controlled. Magnetic resonance imaging is used to monitor cell distribution in the human body, and using artificial magnetic labels such as nanoparticles to track cells may affect cellular metabolism and viability. Through a new genetically encoded label, iron-containing nanoparticles can be synthesized in stem cells without compromising cell viability, enhancing the contrast properties of mesenchymal stem cells in MRI.

Summary: The correlation between crystal structure and magnetic properties is studied in the (1-x)BiFeO3 - (x)BaTiO3 system across the morphotropic phase boundary. As dopant content increases, there is a structural transition from rhombohedral to cubic phase, leading to changes in magnetic structure. The presence of non-zero remanent magnetization is determined by oxygen octahedra tilting rather than structural distortion.

Summary: This study used the differential static magnetic localization method to track permanent magnets on capsule endoscopes and found that the tracking accuracy was high when the magnet length was at least 5 mm. This research fills the gap in current capsule endoscope systems regarding the available information on traveled distance and orientation, providing physicians with more useful information.
