    Opis:
    Kompatybilność „wyższego kontrastu” oraz „pełnej wizualizacji struktury anatomicznej” jest trudna do osiągnięcia w konwencjonalnym przetwarzaniu. Dynamic Visualization II (DV II) jest nową metodą przetwarzania obrazu i pozwala na rozwiązanie tego problemu. Metoda ta oparta jest na nowej technologii, która szacuje grubość i strukturę na podstawie informacji z obrazu RTG, gdzie promienie X penetrują ciało pacjenta. Przedstawiona w tym artykule technika przetwarzania może poprawić wizualizację całej części ciała i może zminimalizować potrzebę dodatkowej korekty gęstości i kontrastu obrazu RTG.
    The compatibility of “higher contrast” and “whole anatomic structure visualization” is difficult to achieve in conventional processing. Dynamic Visualization II, which is a new image-processing method, solves this problem. This processing method is based on a new technology that estimates a patient’s thickness and structure from X-ray image information, which penetrates through the patient’s body. This processing method can improve the visualization of an entire body part and can minimize the need for additional adjustments in the X-ray image’s density and contrast.

    Opis:
    In multi-unit auctions for a single item, the Vickrey–Clarke–Groves mechanism (VCG) attains allocative efficiency but suffers from its computational complexity. Takahashi and Shigeno thus proposed a greedy based approximation algorithm (GBA). In a subject experiment there was truly a difference in efficiency rate but no significant difference in seller’s revenue between GBA and VCG. It is not clear in theory whether each bidder will submit his or her true unit valuations in GBA. We show, however, that in a subject experiment there was no significant difference in the number of bids that obey “almost” truth-telling between GBA and VCG. As for individual bidding behavior, GBA and VCG show a sharp contrast when a human bidder competes against machine bidders; underbidding was observed in GBA, while overbidding was observed in VCG. Some results in a numerical experiment are also provided prior to reporting those observations.

    Opis:
    The single-hole one-electron superexcited states and doubly-excited states of H2, D2, N2 and O2 have been investigated by means of the coincident electron-energy-loss spectroscopy that we developed. In this method the electron-energy-loss spectra tagged with the vacuum ultraviolet fluorescences emitted by the neutral fragments produced from superexcited molecules are measured by means of electron-photon coincidence technique. The contribution from ionization in this sort of electronenergy- loss spectra is suppressed to a large extent, and thus the structures attributed to the superexcited states of molecules become highlighted. The comparison with the photoexcitation experiments by means of the oscillator strengths give us clear discrimination between allowed and forbidden superexcited-states. As to H2, D2, and N2, the doubly-excited states including those found in the present experiment have been investigated in terms of both their energies and dynamical behavior. A new possibility of the coincident electron-energy-loss spectroscopy has been established in investigating the single-hole one-electron superexcited states of O2: the time-resolved coincident electron-energy-loss spectrum has been measured to distinguish between the direct process producing excited oxygen atoms and indirect one due to cascade transition. It has turned out that the coincident electron-energy-loss spectroscopy is a key tool for investigating superexcited molecules.

    Opis:
    Purpose: We examined the reliability of measurements using a newly developed perioral muscle pressure measuring device with a lip piece in healthy adults. Methods: Subjects were 40 healthy men (25.8 years) with normal stomatognathic function. Perioral muscle pressure measuring device with a lip piece was used to measure upper lip, lower lip and tongue pressure, and a balloon-based measurement device was used to measure tongue and cheek pressure. Each measurement was taken twice with a 1-min interval between the two measurements. We determined intra-rater reliability by using the intra-class correlation coefficient as a test of relative reliability. As a test of absolute reliability, Bland–Altman analysis was used to assess systematic bias and the 95% confidence interval of the minimal detectable change was calculated. Additionally, the coefficient of variation was calculated. The Spearman–Brown formula was calculated the number of measurements needed to achieve a confidence coefficient ≥0.9. Each set of measurements was followed by a second set that were taken 1 week later. Results: All measurements showed high values of intra-class correlation coefficient. Upper lip, tongue, and cheek pressure can be determined based on a single measurement, while lower lip pressure requires averaging twice. No systematic bias was observed. The coefficients of variation of measurements were almost the same between the two devices. Conclusion: Measurements were highly reliable regardless of the type of perioral muscles. Our findings suggest that the method described in this study is useful as a quantitative chair side method for examining perioral muscle pressure.

    Opis:
    Erythritol helps both prevent and improve periodontal disease and is therefore widely used for dental care in humans. However, only a few studies have investigated the effects of erythritol on periodontal disease in animals. We hypothesized that erythritol could be used to prevent and improve periodontal disease also in canines and investigated the effects of erythritol on canine periodontal disease–related pathogenic bacteria using both in vitro and in vivo methods. The effect of erythritol on the proliferation of Porphyromonas gulae, which is reportedly associated with canine periodontal disease, was investigated in vitro. In addition, a 4-week intervention trial using an external gel preparation containing 5% erythritol was performed in canines with mild periodontal disease; changes in the microbiota around periodontal lesions were investigated using next-generation sequencing and bioinformatics analysis. The growth of P. gulae was significantly suppressed by erythritol in vitro. In the intervention study, the Shannon index, an indicator of the species distribution α-diversity, and the occupancy of several canine periodontal disease – related bacteria ( P. gulae, P. cangingivalis) were significantly decreased in periodontal lesions. Based on the results of in vitro and in vivo studies, we conclude that, as in humans, erythritol has bacteriostatic effects against periodontal disease – related bacteria in canines.

    Opis:
    Novel nanometer scale structures have been produced by thermal heating or laser irradiation on the surface of single- and multi-layers of C$\text{}_{60}$ and C$\text{}_{84}$ on Si. These structures were examined by combined measurements of scanning tunneling spectroscopy and high resolution electron energy loss spectroscopy. The results show specific chemical reactions of substrate with carbon clusters having single- and double-bonded network. Covalent bonds are formed in some of these chemical reactions.

    Opis:
    We have carried out a powder X-ray diffraction investigation on antiferromagnetic Kondo semiconductors CeRu₂Al₁₀ and CeOs₂Al₁₀ at low temperatures and under high pressures as well as the structural investigation on single crystal of these compounds. The results of powder X-ray studies of CeRu₂Al₁₀ and CeOs₂Al₁₀ indicate that these compounds do not have structural transition at its antiferromagnetic ordering temperature. The results of single crystal structural refinement indicate that the b-axis of this crystal structure is insensitive not only to pressure but also to temperature and that the effect of cooling to Ce-Ce distance for CeRu₂Al₁₀ is the same as that for CeOs₂Al₁₀.
