Abstract

We present highly sampled photometry of the supernova (SN) 2023ixf, a Type II SN in M101, beginning 2 days before its first known detection. To gather these data, we enlisted the global Unistellar Network of citizen scientists. These 252 observations from 115 telescopes show the SN's rising brightness associated with shock emergence followed by gradual decay. We measure a peak $M_{V}$ = -18.18 $\pm$ 0.09 mag at 2023-05-25 21:37 UTC in agreement with previously published analyses., Comment: 4 pages, 1 figure

Abstract

The autoencoder is one of machine learning algorithms used for feature extraction by dimension reduction of input data, denoising of images, and prior learning of neural networks. At the same time, autoencoders using quantum computers are also being developed. However, current quantum computers have a limited number of qubits, which makes it difficult to calculate big data. In this paper, as a solution to this problem, we propose a computation method that applies a convolution filter, which is one of the methods used in machine learning, to quantum computation. As a result of applying this method to a quantum autoencoder, we succeeded in denoising image data of several hundred qubits or more using only a few qubits under the autoencoding accuracy of 98%, and the effectiveness of this method was obtained. Meanwhile, we have verified the feature extraction function of the proposed autoencoder by dimensionality reduction. By projecting the MNIST data to two-dimension, we found the proposed method showed superior classification accuracy to the vanilla principle component analysis (PCA). We also verified the proposed method using IBM Q Melbourne and the actual machine failed to provide accurate results implying high error rate prevailing in the current NISQ quantum computer., Comment: 8 pages, 7 figures

Abstract

Micron-scale single-crystal nanowires of metallic TaSe3, a material that forms -Ta-Se3-Ta-Se3- stacks separated from one another by a tubular van der Waals (vdW) gap, have been synthesized using chemical vapor deposition (CVD) on a SiO2/Si substrate, in a process compatible with semiconductor industry requirements. Their electrical resistivity was found unaffected by downscaling from the bulk to as little as 7 nm in width and height, in striking contrast to the resistivity of copper for the same dimensions. While the bulk resistivity of TaSe3 is substantially higher than that of bulk copper, at the nanometer scale the TaSe3 wires become competitive to similar-sized copper ones. Moreover, we find that the vdW TaSe3 nanowires sustain current densities in excess of 108 A/cm2 and feature an electromigration energy barrier twice that of copper. The results highlight the promise of quasi-one-dimensional transition metal trichalcogenides for electronic interconnect applications and the potential of van der Waals materials for downscaled electronics.

Abstract

InAs nanowires (NWs) were grown on SiOx pinholes formed on Si(111) substrates by molecular beam epitaxy. Influences of electron-beam (EB) irradiation on the SiOx layer on the pinhole formation and the subsequent InAs NW growth were studied. As the EB irradiation dose increased, the pinhole density in the SiOx layer decreased. From atomic force microscopy, transmission electron microscopy, and x-ray photoelectron spectroscopy results, it was found that the pinhole etching of the SiOx layer by Ga droplets was suppressed by carbon adsorption due to the EB irradiation. By forming high-density pinholes on the SiOx layer without the EB irradiation, high-density InAs NWs with 1–2 × 1010 cm−2 were grown successfully, and the uniformity in the NW diameter improved. The standard deviation of the NW diameter was 1.8 nm (8.8%) for high-density NWs. In addition, the NW diameter decreased with decreasing EB dose, and the NW diameter was controlled by adjusting the diameter of Ga droplets forming the pinholes. As the NW diameter decreased, photoluminescence spectra of the NWs shifted to higher energies than the bandgap energy of the wurtzite InAs bulk. From these results, we successfully fabricated high-density and high-uniformity InAs NWs with quantum size effects on EB-unirradiated SiOx/Si(111). [ABSTRACT FROM AUTHOR]

Abstract

The hot carrier dynamics and its effect on the device performance of GaAs solar cell and InAs/GaAs quantum dot solar cell (QDSC) was investigated. At first, the fundamental operation feature of conventional hot carrier solar cell was simulated based on the detailed balance thermodynamic model. Then we investigated the hot carrier dynamics in the normal junction based solar cell using hydrodynamic/energy Boltzmann transportation model (HETM) where the two temperature (carrier temperature and lattice temperature are treated separately. For the first time, we report an inherent quasi-equivalence between the detailed balance model and HETM model. The inter-link revealed here addresses the energy conservation law used in the detailed balance model from different angle and it paves a way toward an alternative approach to curtail the selective contact constraints used in the conventional hot carrier solar cell. In simulation, a specially designed InAs/GaAs quantum dot solar cell was used in the simulation. By varying the hot carrier energy relaxation time , an increase in the open circuit voltage was clearly found with the increase of . Detailed analysis was presented regarding the spatial distribution of hot carrier temperature and its interplay with electric field and three hot carrier recombination processes (Auger, SRH and radiative), Comment: There are major issues in the contents

Abstract

Objective: Anti–histidyl‐transfer RNA synthetase (Jo‐1) antibodies are associated with myositis as well as different extramuscular organ complications comprising the anti‐synthetase syndrome. This study aimed to clarify the relationship between anti–Jo‐1 epitope recognition patterns and specific clinical features of this syndrome. Methods: B cell epitope mapping was performed via enzyme‐linked immunosorbent assay in 180 patients who were anti–Jo‐1 antibody‐positive using overlapping peptides/protein fragments spanning the amino‐terminal 151 amino acids of Jo‐1 as substrate antigens. Statistical associations with clinical features were assessed through rank‐sum, correlation, and cluster analyses. Results: The level of reactivity against subfragments spanning amino acids 1–151 of Jo‐1 paralleled that of full‐length Jo‐1, confirming the immunodominance of this amino‐terminal region. The corresponding frequencies of reactivity to peptides 1 (amino acids [aa] 1–21), 3 (aa 27–47), 4 (aa 40–60), 10 (aa 118–138), and 11 (aa 131–151) were 6.1%, 42.5%, 6.8%, 6.7%, and 20.3%. While anti–full‐length Jo‐1 antibodies were significantly associated with Raynaud phenomenon, anti‐fragment A2 (aa 1–60) and A3 (aa 1–90) antibodies were associated with proximal muscle weakness, Raynaud phenomenon, arthritis, and sicca syndrome. Anti‐fragment A4 (aa 1–120) and A5 (aa 1–151) antibodies were also associated with sicca syndrome. Peptide 1 (aa 1–21) antibodies were associated with Raynaud phenomenon and dysphagia. Whereas anti‐peptide 3 (aa 27–47) antibodies were also linked to Raynaud phenomenon, anti‐peptide 9 (aa 105–125) antibodies were associated with mechanic's hands. Conclusion: Autoantibodies targeting different amino‐terminal subfragments and/or peptides of Jo‐1 were associated with specific clinical features of the anti‐synthetase syndrome, demonstrating the biomarker potential of B cell epitope profiling in this disorder.

Abstract

Objectives Anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive (MDA5+) dermatomyositis patients exhibit a variety of clinical features. We therefore investigated whether patterns of B-cell epitope recognition are linked to the clinical course of MDA5+ dermatomyositis. Methods Our cross-sectional study used ELISA-based methods to determine the relationship between antibody recognition of overlapping 155 amino acid MDA5 subfragments and clinical features of 24 MDA5+ myositis patients. Correlations between clinical features and standardized anti-MDA5 subfragment antibody titres were assessed via Spearman's rank correlation coefficients. Results Twenty-four MDA5+ patients submitted serum samples within a median of 0 (interquartile range, 0–74) days from the initial clinic visit. In addition to typical dermatomyositis rashes, these patients exhibited muscle symptoms (n  = 11), vascular dysfunction (n  = 9) and interstitial lung disease (ILD) (n  = 16). Female patients exhibited higher titres of antibodies recognizing fragment H (aa 905–1026) compared with male patients. Muscle involvement was associated with higher levels of anti-fragment F (aa 646–801) antibody. Conversely, patients with vascular abnormalities had higher anti-fragment B (aa 130–284) and E (aa 517–671) antibody titres than those without vascular dysfunction. Four patients died due to ILD progression and showed higher anti-fragment A (aa 1–155) antibody titres than the other 20 patients. Differences in the ratio of anti-fragment to anti-full-length MDA5 antibody titres were found for sex (H: anti-MDA5) and vascular dysfunction (anti-fragment B, E: anti-MDA5). Conclusions Various clinical features of MDA5+ dermatomyositis correlated with levels of antibodies targeting selected subfragments of this autoantigen, providing a link between fragment-specific immune responses and disease course.

Abstract

BACKGROUND: Pre-discharge home assessment visits for elderly hospitalized patients are conducted by the hospital staff to ensure a smooth transition to home care and are effective in preventing falls and reducing the rehospitalization rates. However, the effect of an application that enables the viewing of videos of the patient’s home activities during the pre-discharge visit on the multidisciplinary professionals who provide services to the patient has not yet been fully clarified. METHODS: Multidisciplinary professionals at 23 facilities located in western Tottori Prefecture who used a video-sharing application (Patto-Mie Net) were invited to be interview participants. Those who agreed were interviewed about the usefulness of the application in their work and its effect on multidisciplinary collaboration. A verbatim transcript was made, and thematic analysis was conducted using the qualitative analysis software NVivo. RESULTS: Twenty-eight people participated in the interviews, including nurses, care managers, rehabilitation specialists, care workers, and other social care professions. Fourteen themes and five categories were generated from the analysis: comprehensive information visualization and transferability, identification of changes over time and prognostic prediction, promoting multidisciplinary collaboration, patient and family reality, and disadvantages and concerns. CONCLUSION: The use of an application that allows video-sharing of a patient’s home movement status during a pre-discharge visit has revealed a variety of benefits for multiple professionals in hospitals and other facilities. In particular, the results were characterized by the psychological closeness between multiple professionals, promotion of interprofessional communication, and sharing of reality, including the psychosocial background of the patient and family.

34. A Study of the Catalysis of MoS2 using Optical Photoluminescence

Abstract

Monolayer molybdenum disulfide (MoS2) has many unique characteristics, one of which is a strong photoluminescence (PL) excitation due to its direct band gap property. Because of this characteristic, the surface morphologies can be inferred by studying the photoluminescence peak frequency and intensity. Regions where the surface is disrupted by changes in structural phase and defect density will be indicated by the PL fluctuations. We have investigated the hydro-desulfurization (HDS) catalysis using this MoS2 response by widefield PL imaging. This wide field PL imaging technique has the advantage of shorting each acquisition time of a large sample area to 1-2 minutes instead of hours required for mapping scans. Within this time frame, surface morphology changes from temperature under a hydrogen environment and dosing a sulfur containing organic compound, benzenethiol, studied in real time. We have also studied the reaction efficiency using gas chromatography (GC) with a mass spectrometer for the same condition as in the PL widefield imaging experiments. We have found PL image activities in pre-HDS temperatures around 200°C to 300°C. Although PL intensity gets small, there are some PL activities in HDS temperatures between 300°C to 400°C and little over this temperature. We have observed HDS conversion in this temperature regime as well as hydrogen sulfide (H2S) on our GC system. It was not only edges but also the basal region which had PL intensity fluctuation. This activity may imply the HDS in both the edges and the basal plane, unlike previous belief that edges are the sole active catalytic sites.
