Historical and current aerial photographs are only of great value if the geolocation or address of the photographed areas is also available. In Western Europe, especially Austria, Germany and Czech Republic, there is a market for the sale of aerial photographs of one’s own private residential building. Automated geolocation is a feasible way to enable the sales agents to assign the addresses for the sale more quickly. In the course of this research work, a process chain is modeled that allows the assignment of aerial photographs to residential addresses using machine vision. After model-based rectifying the aerial images to compensate for perspective distortions, larger image blocks get assembled using image stitching. The assignment to a 2D reference map, such as satellite imagery via Google Maps, is done by applying a U-Net CNN after extracting durable image features such as roads or buildings. The mapping of aerial imagery to two-dimensional cartography is either automated via registration approaches or based on manually placed corresponding landmarks and homography. Test runs on imagery between the years 1969 and 2020 show that the labor-intensive process of geolocation of aerial imagery can be solved by the proposed process model in a hybrid way. © 2022 The Authors.

Hydrolysis of Zr（BH4）4·8NH3in deionized water can generate high purity hydrogen at room ***, the sluggish hydrolysis kinetics of Zr（BH4）4·8NH3hinders its practical use. To improve its hydrogen generation properties, the effects of magnetic stirring, changing hydrolysis solution and tuning the ammonia coordination number on the hydrolysis properties of Zr（BH4）4·8NH3were investigated. Results show that both changing hydrolysis solution and tuning the ammonia coordination number can enhance the hydrolysis *** hydrolysis kinetics properties of Zr（BH4）4·8NH3were significantly improved in MgCl2and *** Zr（BH4）4·8NH3（x ≤ 8） samples were synthesized by a ball-milling method with different ammonization time（10, 60 and 180 min）. Both the hydrolysis kinetics and hydrogen yield of Zr（BH4）4·8NH3（x ≤ 8） were enhanced as the ammonia coordination number（x） decreased. Thus, tuning ammonia coordination number is an effective way to control the hydrolysis properties of Zr（BH4）4·8NH3（x ≤ 8）.

Dispersion relation and optical transmittance of a hexagonal photonic crystal slab

The dispersion relation and the optical transmittance of a two-dimensional photonic crystal composed of the hexagonal array of cylindrical air holes fabricated in a dielectric slab were analyzed by group theory and the numerical calculation based on the finite-difference time-domain method. The decay rate of the leaky modes that exist above the light line (the dispersion relation in air) in the band diagram was also evaluated, from which the absence of the coupling between certain internal eigenmodes and the external radiation field was shown. This phenomenon was related to symmetry mismatching by the group-theoretical argument. It was also shown that a certain leaky band has a quality factor as large as 3000 over its entire spectral range. These features as well as the opaque frequency regions due to symmetry mismatching were clearly demonstrated by the calculated optical transmission spectra.

In 1907, Lapicque proposed that an electric field passes through the neuronal membrane and transmits a signal. Subsequently, a “snake curve” or spike was used to depict the means by which a linear flat current undergoes a sudden Gaussian or Laplacian peak. This concept has been the accepted scenario for more than 115 years even appearing in textbooks on the subject. It was not noted that the membrane spike should have a cylindrical shape. A nerve spike having a dot shape on membrane surface cannot propagate through a cylindrical surface since it would dissipate instantaneously. A nerve spike should have the appearance of a ring, encompassing the diameter of a cylindrical axon or dendron. However, this subtle change has remarkable implications. Maintaining a circular form of an electric field is not easy, especially at the surface of an organic object. Here, we suggest that neuroscience could redefine itself if we accept that a nerve spike is not a localized 3D Gaussian or Laplacian wave packet, rather it is a 3D ring encompassing the diameter of a neural branch. © 2022 The Author(s).

In this study, we performed systematic search for dopants to stabilize the tetragonal structure of HfO2 and ZrO2 by using first-principles calculations. Whole impurity configurations within the supercell, more than 12,000 systems, are examined and the most stable configurations are assumed to be realized. We reveal the contributions of the dopants to the structural stability of tetragonal phase, and that Si or Ge significantly stabilize the tetragonal phase. © 2022 IEEE.

Two-dimensional（2D） ferromagnetic materials have been discovered with tunable magnetism and orbital-driven nodal-line features. Controlling the 2D magnetism in exfoliated nanoflakes via electric/magnetic fields enables a boosted Curie temperature（TC） or phase transitions. One of the challenges, however, is the realization of high TC2D magnets that are tunable, robust and suitable for large scale fabrication. Here, we report molecular-beam epitaxy growth of wafer-scale Fe3+XGeTe2films with TCabove room temperature. By controlling the Fe composition in Fe3+XGeTe2, a continuously modulated TCin a broad range of 185–320 K has been achieved. This widely tunable TCis attributed to the doped interlayer Fe that provides a 40% enhancement around the optimal composition X = 2. We further fabricated magnetic tunneling junction device arrays that exhibit clear tunneling signals. Our results show an effective and reliable approach, i.e. element doping, to producing robust and tunable ferromagnetism beyond room temperature in a large-scale 2D Fe3+XGeTe2fashion.

Many types of agricultural facilities have been constructed at many places around the world. Although most of the operations are mechanized at these facilities, high noise from mechanical systems often prevents operators from discharging their duties efficiently and results in an unsafe environment. Virtual low-noise space is defined as the space required by operators in order to smoothly communicate in a high-noise environment, i.e., they feel as though they are working in a low-noise environment. The virtual low-noise space has three functions: to reduce the noise around the operators' ears, to communicate by speech without noise, to recreate the audio image on the basis of the operators' mutual positions. In this research, virtual low-noise space was constructed using noise-canceling headphones, microphones, a TV camera, and computers.

This work describes the synthesis of periodic mesoporous organosilica (PMO@Py NPs) nanocarriers that integrate the hydroxyl-pyridyl (HP) ligand and could be used as an efficient drug delivery system in the presence of varying pH stimuli. PMO@Py NPs were produced by adapting the sol-gel co-condensation process. X-ray diffraction (XRD), Fourier-transform infrared (FTIR), N2 adsorption-desorption analysis, particle size analysis, and zeta potential measurements were used to characterize the produced PMO@Py NPs. The developed silica nanocarriers' surface morphology was observed by scanning electron microscopy (SEM) study. The content of integrated organic functional groups in the PMO@Py NPs was determined using elemental analysis and thermogravimetric (TG) analysis. To ascertain the loading and pH-responsive release efficiency of the PMO@Py NPs under various pH (pH 7.4, 6.2, and 4.5) circumstances, respectively, the hydrophilic anticancer agent 5-Fu was utilized as a model drug. Furthermore, in MDA-MB-231 cells, the biocompatibility of the PMO@Py NPs was assessed. Additionally, utilizing samples of red blood cells, produced PMO@Py NPs' hemocompatibility was assessed and compared with that of the positive control, Triton-X. Overall, the results showed that the HP-PMO@Py NPs that have been generated are biocompatible, have a high drug loading capacity (about 85%), and release the drugs that were loaded under different pH stimulation conditions. © 2025 Walter de Gruyter GmbH, Berlin/Boston.

Aerial photographs of buildings are often used as memorabilia sold by trading companies. Such photographs come with an issue regarding the address of the shown buildings, since the recording location of the camera may be known, but shows a spatial distance to the actual subject of the image. In addition to that, also this recording location is often not known in detail but only roughly in the form of the flight route/area. To address this problem, a methodology for reverse geocoding is proposed, allowing to identify the position of buildings that are photographed from aerial vehicles. This is done using a process for extending recording locations and a second process based on the registration of invariant features within aerial shots compared to maps. © 2022 University of West Bohemia.
