Get PDF富山市科学博物館では，平成27年7月18日から9月6日まで特別展「地球の結晶～北川隆司鉱物コレクション～」を開催した．本展では，北川隆司氏のコレクションを中心に，色や結晶の美しい鉱物標本約300点と㈲J．C．BAR所有の宝石標本約100点を展示した．本展では，鉱物の色や結晶の形の美しさを伝えるとともに，鉱物の様々な楽しみ方を提案することを狙いとし展示を構成した．展示の構成・デザインには，（１）来場者に展示の意図が伝わること，（２）当館の来館者層（幼児～小学生＋その保護者）にあった内容であること，（３）特に鉱物に興味をもたない来場者でも楽しめる展示であることに注意した．
本展開催期間中，来場者に本展の感想を問うアンケートを実施した．その結果，印象に残った展示として「宝石」を筆頭に，「光る石や色が変わる石」「鉱物の色」「鉱物の形」と回答した方が多く，自由記述においても，「きれいだった」といった感想が多く見られ，本展の狙いは概ね達成したと言える．For exhibits held at museums, curators plan and create exhibits matched to the nature of the exhibit venue and the visitors expected, carefully structuring the exhibit to suit the museum in question. The standard theory of exhibits has been discussed in various literature, but there have been few elucidations of the subtle exhibition techniques employed by curators. From July 18, 2015 through September 6, 2015, the Toyama Science Museum held an exhibit entitled: Crystallization of the Earth: The Ryuji Kitagawa Mineral Collection. This paper explains the exhibitional techniques that the author did in the exhibition. Further, the results of a survey distributed to visitors are used to assess future issues surrounding how exhibition techniques are evaluated by the public.departmental bulletin pape
Mechanical properties of Cu-Ni alloy thick films electrodeposited from aqueous solution containing pyrophosphate as a complexing agent
Get PDFCu-Ni alloy thick films with a thickness of approximately 170 µm were electrodeposited from an aqueous solution containing pyrophosphate as a complexing agent. The electrodeposited Cu-Ni alloy thick films with a dumbbell shape were exfoliated from a metallic titanium cathode to examine the crystal orientation, microhardness and tensile strength. The average crystallite size of electrodeposited Cu-Ni alloy thick films was around 30 nm. The microhardness increased up to 327 HV with increasing the Ni content up to ∼19 % while the maximum tensile strength reached 726 MPa at the Ni content of ∼13 %. The improvement of these mechanical properties can be explained by two strengthening mechanisms of solid solution alloying and crystallite size refining.Journal of Alloys and Compounds, 1026, art. no. 180398; 2025journal articl
Voice Compression and Communications: Principles and Applications for Fixes and Wireless Channels
No full textUp-to-date, expert coverage of topics in wireless voice communications Voice communication is the most important facet of mobile radio service. Even when the predicted surge of wireless data and Internet services becomes a reality, voice will remain the most natural means of human communication. Voice Compression and Communications details issues in wireless voice communications and treats compression, channel coding, and wireless transmission as a joint subject. Part I covers background material, whereas Part II provides detailed information on both proprietary and standardized analysis-by-synthesis codecs, including the speech codecs of virtually all existing wireline-based and wireless systems. Parts III and IV discuss mainly research-based wideband, audio, as well as very low-rate schemes likely to find their way into future standards. Voice Compression and Communications describes fundamental concepts in a non-mathematical way early in the book for those with only a background knowledge of signal processing and communications. More advanced readers will find detailed discussions of theoretical principles, future concepts, and solutions to various specific wireless voice communications problems
Zooplankton diversity analysis through single-gene sequencing of a community sample
Get PDFAbstract Background Oceans cover more than 70% of the earth's surface and are critical for the homeostasis of the environment. Among the components of the ocean ecosystem, zooplankton play vital roles in energy and matter transfer through the system. Despite their importance, understanding of zooplankton biodiversity is limited because of their fragile nature, small body size, and the large number of species from various taxonomic phyla. Here we present the results of single-gene zooplankton community analysis using a method that determines a large number of mitochondrial COI gene sequences from a bulk zooplankton sample. This approach will enable us to estimate the species richness of almost the entire zooplankton community. Results A sample was collected from a depth of 721 m to the surface in the western equatorial Pacific off Pohnpei Island, Micronesia, with a plankton net equipped with a 2-m2 mouth opening. A total of 1,336 mitochondrial COI gene sequences were determined from the cDNA library made from the sample. From the determined sequences, the occurrence of 189 species of zooplankton was estimated. BLASTN search results showed high degrees of similarity (>98%) between the query and database for 10 species, including holozooplankton and merozooplankton. Conclusion In conjunction with the Census of Marine Zooplankton and Barcode of Life projects, single-gene zooplankton community analysis will be a powerful tool for estimating the species richness of zooplankton communities.</p
Anti-ganglionic acetylcholine receptor antibodies in Functional Neurological Symptom Disorder/Conversion Disorderr
No full text博士論文全文, 博士論文要旨, 最終試験結果の要旨, 論文審査の要旨Objective: Autoimmune autonomic ganglionopathy (AAG) is a rare disorder characterized by autonomic failure associated with the presence of anti-ganglionic acetylcholine receptor (gAChR) antibodies; however, several studies have reported that individuals with anti-gAChR antibodies present with central nervous system (CNS) symptoms such as impaired consciousness and seizures. In the present study, we investigated whether the presence of serum anti-gAChR antibodies correlated with autonomic symptoms in patients with functional neurological symptom disorder/conversion disorder (FNSD/CD).
Methods: Clinical data were collected for 59 patients presenting with neurologically unexplained motor and sensory symptoms at the Department of Neurology and Geriatrics between January 2013 and October 2017 and who were ultimately diagnosed with FNSD/CD according to the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. Correlations between serum anti-gAChR antibodies and clinical symptoms and laboratory data were analyzed. Data analysis was conducted in 2021.
Results: Of the 59 patients with FNSD/CD, 52 (88.1%) exhibited autonomic disturbances and 16 (27.1%) were positive for serum anti-gAChR antibodies. Cardiovascular autonomic dysfunction, including orthostatic hypotension, was significantly more prevalent (75.0 vs. 34.9%, P = 0.008), whereas involuntary movements were significantly less prevalent (31.3 vs. 69.8%, P = 0.007), among anti-gAChR antibody-positive compared with -negative patients. Anti-gAChR antibody serostatus did not correlate significantly with the frequency of other autonomic, sensory, or motor symptoms analyzed.
Conclusions: An autoimmune mechanism mediated by anti-gAChR antibodies may be involved in disease etiology in a subgroup of FNSD/CD patients.Ryusei Nagata, Eiji Matsuura, Satoshi Nozuma, Mika Dozono, Yutaka Noguchi, Masahiro Ando, Yu Hiramatsu, Daisuke Kodama, Masakazu Tanaka, Ryuji Kubota, Munekazu Yamakuchi, Yujiro Higuchi, Yusuke Sakiyama, Hitoshi Arata, Keiko Higashi, Teruto Hashiguchi, Shunya Nakane and Hiroshi Takashima

Depth dependence and exponential models of permeability in alluvial-fan gravel deposits
Get PDFTo determine depth dependence of permeability in various geologic deposits, exponential models have often been proposed. However, spatial variability in hydraulic conductivity, K, rarely fits this trend in coarse alluvial aquifers, where complex stratigraphic sequences follow unique trends due to depositional and post-depositional processes. This paper analyzes K of alluvial-fan gravel deposits in several boreholes, and finds exponential decay in K with depth. Relatively undisturbed gravel cores obtained in the Toyohira River alluvial fan, Sapporo, Japan, are categorized by four levels of fine-sediment packing between gravel grains. Grain size is also analyzed in cores from two boreholes in the mid-fan and one in the fan-toe. Profiles of estimated conductivity, , are constructed from profiles of core properties through a well-defined relation between slug-test results and core properties. Errors in are eliminated by a moving-average method, and regression analysis provides the decay exponents of with depth. Moving-average results show a similar decreasing trend in only the mid-fan above 30-m depth, and the decay exponent is estimated as a parts per thousand 0.11 m(-1), which is 10- to 1,000-fold that in consolidated rocks. A longitudinal cross section is also generated by using the profiles to establish hydrogeologic boundaries in the fan
Object-based spatial attention when objects have sufficient depth cues
Get PDFAttention directed to a part of an object tends to obligatorily spread over all of the spatial regions that belong to the object, which may be critical for rapid object-recognition in cluttered visual scenes. Previous studies have generally used simple rectangles as objects and have shown that attention spreading is reflected by amplitude modulation in the posterior N1 component (150-200 ms poststimulus) of event-related potentials, while other interpretations (i.e., rectangular holes) may arise implicitly in early visual processing stages. By using modified Kanizsa-type stimuli that provided less ambiguity of depth ordering, the present study examined early event-related potential spatial-attention effects for connected and separated objects, both of which were perceived in front of (Experiment 1) and in back of (Experiment 2) the surroundings. Typical P1 (100-140 ms) and N1 (150-220 ms) attention effects of ERP in response to unilateral probes were observed in both experiments. Importantly, the P1 attention effect was decreased for connected objects compared to separated objects only in Experiment 1, and the typical object-based modulations of N1 were not observed in either experiment. These results suggest that spatial attention spreads over a figural object at earlier stages of processing than previously indicated, in three-dimensional visual scenes with multiple depth cues
