This paper presents a methodological defense of The Silver Edge as a central component of a unified creative and scholarly research program. Although fiction is often treated as separate from academic inquiry, the novella is used here as a deliberate extension of the symbolic and comparative frameworks established in earlier studies. Drawing on comparative poetics, symbolic anthropology, hermeneutic interpretation, and narrative theory, the paper argues that creative practice can generate forms of knowledge that complement analytical scholarship. The Silver Edge provides a narrative environment in which twilight cosmology, spiritual reciprocity, and moral agency can be examined with precision. Through critical reading, cultural contextualization, and theoretical integration, the paper illustrates that the novella represents more than an optional creative component to the project, being an indispensable element of the intellectual structure underpinning the work. It explores the impact of critical narration and creative inquiry on symbolic structures, an area that could be abstract in critical writing, and the merits of creative work toward being an attuned, rigorous inquiry mode for the humanities.

Dominant magnetic properties have been shown in Heusler alloys and local magnetic moment have been strongly associated with the Mn and Co based half and full-Heusler based materials. These alloys have exhibited the highest magnetic moment so for in comparison to other alloys, compound and composite materials. Magnetic moments are found to be localized around the atoms subsequently depends on the chemical surrounding of atoms. Limited swapping of atoms lead to significantly reduces the magnetic moment in these alloys. Therefore, it is necessary to evaluate the extent of swapping of atoms between the alloys. In order to evaluate the effect of replacement of p group element in Ni 2 MnSb, we have used the vesta software and calculated the ratio of super reflection peaks. Moreover, we have also introduced the spontaneous swapping of atoms due to their equivalent electronegativity and atomic size. Spontaneous swapping gives rise to the enhancement/reduction of magnetic moments because magnetic moments are mainly governed by the total valence electron count (VEC) of the substituted elements.

Abstract Novel compounds having the formulae (AuxCu1‒x)Sr2CaCu2Oy ((Au,Cu)‐1(Sr)212) and Sr2Ca2(Au,Cu)3Oy (0(Sr)223) and exhibiting superstructures were synthesized at 5.5 GPa and 1100°C‒1150°C. The structures of these materials were assessed using X‐ray diffraction and field emission transmission electron microscopy. The sub‐structures of the resulting (Au,Cu)‐1(Sr)212 and 0(Sr)223 phases were found to have the lattice parameters a ≈ 3.86 Å and c ≈ 10.98 Å and a ≈ 3.88 Å and c ≈ 27.21 Å, respectively. Analyses by X‐ray photoelectron spectroscopy indicated that the Au in these compounds was primarily in the Au3+ state. (Au,Cu)‐1(Sr)212 specimens with Au/Cu ratios ≥0.3 and 0(Sr)223 specimens with Au/Cu ratios ≥0.25 exhibited superstructures. The ordered arrangements of Au and Cu in the charge reservoir layers and the CuO2 planes likely generated these superstructures.

Abstract Micropillar compression (microcompression) is a promising technology for studying the intrinsic strength and plasticity of macroscopically brittle ceramics. However, their ductility limits at microscopic scale have rarely been investigated. This study digests the orientation dependence of the strength and ductility of various oxide single crystals with cubic structures (9.8‐mol% Y 2 O 3 ‐stabilized ZrO 2 , Y 2 O 3 , MgAl 2 O 4 , and SrTiO 3 ) using room‐temperature microcompression, electron microscopy observation, and crystal plasticity finite element method simulation. The strength and ductility of these oxides exhibited remarkable orientation dependence. Specifically, the ZrO 2 [111] and SrTiO 3 [001] pillars demonstrated substantial ductility with no visible cracks, even at nominal strains of approximately 40%. The ductility may be attributed to mechanisms suppressing slip localization without causing dislocation interlocking. Multiple‐slip activation was preferred across several slip modes of ZrO 2 , Y 2 O 3 , and MgAl 2 O 4 , which was attributed to the forest‐cutting interactions among dislocations of different slip systems. In contrast, the ductility of SrTiO 3 required the activation of a single slip, where slip localization was suppressed by the strain transfer associated with the formation of Lüders band. The relationship between ductility and slip activation may be influenced by the competition between the Peierls mechanism and dislocation–impurity interactions.

In the last decades, many publicly available large fundus image datasets have been collected for diabetic retinopathy, glaucoma, and age-related macular degeneration, and a few other frequent pathologies. These publicly available datasets were used to develop a computer-aided disease diagnosis system by training deep learning models to detect these frequent pathologies. One challenge limiting the adoption of a such system by the ophthalmologist is, computer-aided disease diagnosis system ignores sight-threatening rare pathologies such as central retinal artery occlusion or anterior ischemic optic neuropathy and others that ophthalmologists currently detect. Aiming to advance the state-of-the-art in automatic ocular disease classification of frequent diseases along with the rare pathologies, a grand challenge on “Retinal Image Analysis for multi-Disease Detection” was organized in conjunction with the IEEE International Symposium on Biomedical Imaging (ISBI - 2021). This paper, reports the challenge organization, dataset, top-performing participants solutions, evaluation measures, and results based on a new “Retinal Fundus Multi-disease Image Dataset” (RFMiD). There were two principal sub-challenges: disease screening (i.e. presence versus absence of pathology — a binary classification problem) and disease/pathology classification (a 28-class multi-label classification problem). It received a positive response from the scientific community with 74 submissions by individuals/teams that effectively entered in this challenge. The top-performing methodologies utilized a blend of data-preprocessing, data augmentation, pre-trained model, and model ensembling. This multi-disease (frequent and rare pathologies) detection will enable the development of generalizable models for screening the retina, unlike the previous efforts that focused on the detection of specific diseases.

In order to confirm the effect of the difference in module sizes of micro-cross-helical-gears on the load-carrying-capacity, we compare the failure modes of module 0.1 mm and module 0.2 mm. We carried out acceleration endurance test on a micro-cross-helical-gear under the lubricant dropping condition only at the start of the experiment. As a result, in case of module 0.2 mm, extremely minute wear powder was spread thinly over the entire tooth surface, which was quite different from the tendency of wear powder in modules 0.1 mm. Micro-crossed-helical-gear of module 0.2 mm had failed tooth tips due to progressive wear, module 0.1 mm showed progressive wear, but did not experience failures at the tooth tips. This is most likely due to the influence of the micro-crossed-helical gear specifications, especially the same tooth width. A comparison was also made in terms of the area of the contact ellipse, and it was found that the increase in contact area per step was larger for the module 0.2 mm. This means that the maximum Hertzian pressures increase per step is also larger, and the magnitude of the load applied to the tooth surface during a single test is also different for each module. Therefore, differences in modules may affect the area of the contact ellipse and the associated maximum Hertzian pressure, which may also have an effect on lifetime.

Recently, Micro Air Vehicle (MAV) has been actively developed. It’s used in various situations, such as exploration of Mars, intelligence gathering at the scene of a terrorist attack. In these situations, MAV needs to be able to keep flying in strong crosswinds and turbulence. These conditions can be seen during flight of flying animals such as birds and insects. Their flight has the characteristics of high maneuverability and robustness for disturbances such as high winds and gusts. The purpose of this study is to research the aerodynamic characteristics of bird’s flapping wing and to develop a small bird-like flying robot depending on a biomimetic approach. We mainly focused on the structure of primary feathers. In the upstroke period, small gap is created between each of primary feathers. This structure allows the birds to reduce drag and get thrust. We designed and manufactured bird-type wings that mimic this structure and compared them with an elliptical wing by aerodynamic force measurement. As a result, the bird-type wings showed good aerodynamic characteristics such as reduced drag and more lift-drag ratio effectively. In addition, we tried to develop a small bird-like flying robot using the birds’ wing structure that can wireless control. Currently, we carry out flight experiments using the robot and develop automatic stable flight control system using barometric pressure sensor and 9-axis sensor.
