Electrochemical performance of cobalt-doped NiO thin films synthesized by spray pyrolysis

ABSTRACT In this work, various cobalt-doped NiO thin films have been synthesized via the spray pyrolysis. The cobalt-doped NiO thin films show a cubic phase with preferred orientation along the (111) plane. The scanning electron microscopy images of the cobalt-doped NiO thin films show interconnected flakes with small agglomerated particles. The optical bandgap decreases from 3.30 eV for the undoped NiO thin film to 2.90 eV for 20 mol% cobalt doping, with an increase in cobalt doping concentration in NiO. The electrochemical activities have been tested in 2M KOH electrolyte with cyclic voltammetry, galvanostatic charge–discharge and electrochemical impedance spectroscopy. The highest specific capacitance observed for the 10 mol% cobalt-doped NiO thin film electrode is 760 Fg−1 at a scan rate of 5 mVs−1. The 10 mol% cobalt-doped NiO thin film electrode shows 92% retention in capacitance after 1000 cycles and a low charge transfer resistance of 10 Ωcm2.

Visual Communication Method of Multi-Frame Film and Television Special Effects Images Based on Deep Learning

In the view of art form change, there is a perspective problem in the detail part of multi-frame film and television special effects (TSEs) images in the special effects rendering module, which leads to the greater ambiguity of multi-frame film and TSEs images. In order to advance the talent of identifying the detail structures and characteristics of multi-frame film and TSEs images, a visual communication technology of multi-frame film and TSEs images in the view of art form change grounded on deep learning is suggested. The transmission relation model of detail characteristics of multi-frame film and TSEs images in the field of artistic form change is constructed, and the attenuation treatment of detail action special effects of multi-frame film and TSEs images in the field of artistic form change is carried out with the assistance of deep learning approaches. The detailed information and color of multi-frame film and TSEs images are obtained by using prior map knowledge instead of rendering basic color. Over the technique of filtering and preserving, the multi-frame film and TSEs images are directed to screen the detailed feature quantity of the input film and TSEs images in the field of artistic form change. In addition, the Sobel operator is practiced to perceive the scrawny edge information of multi-frame film and TSEs images, and block fitting interpolation and depth filtering analysis are used in the edge area to realize the visual communication and color feature parameter identification and amplification of multi-frame film and TSEs images in the field of artistic form change, so as to improve the fuzzy enhancement of multi-frame film and TSEs images. The test results and results indicate that the average Peak signal-to-noise ratio (PSNR) of the proposed method is about 37.7166[Formula: see text]dB, which is 49.08% and 52.08% higher than the PSNRs of the Harris method and SUFR method, respectively. It has been confirmed that this scheme can successfully solve the edge blurring and distortion problems of multi-frame movies and image images in the field of art form change.

Drawn to the light: Cinematic and Performative Ecologies in Stan Brakhage's Mothlight (1963) and Eiko Otake's Night with Moths (2019)

The purpose of this essay is to explore the evocative use of moths within cinematic and performative contexts. To do so, two moving image works were chosen, each framed within in a comparative context to the other: the first, the historic and iconic masterwork of avant-garde cinema by the legendary filmmaker Stan Brakhage titled Mothlight (1963), and the second, a contemporary performance video titled Night with Moths (2019) by the interdisciplinary movement-based artist, Eiko Otake. With their attraction to light, along with their fluttering, nocturnal flights, moths seem to have a strong kinship with not only the moving images of cinema, but also with the movement focus of dance and performance. Indeed, the very presence of moths in both moving image works, invites us to witness compelling cinematic and performative collaborations that move across species and ecologies.

Reporting a Rare HLA Allele with Sequence Analysis Prevents Potentially Lethal Allopurinol Hypersensitivity Reaction

Abstract Introduction/Objective In addition to their essential role in histocompatibility testing, human leukocyte antigen (HLA) alleles have informative pharmacogenomic and disease associations. For example, HLA-B*58:01 carriers have 100- fold greater risk of allopurinol hypersensitivity syndrome (AHS), a lethal T-cell mediated Type IV reaction with a 20- 25% mortality rate. To prevent AHS, patients are tested for carrier status before treatment. Methods/Case Report Patient presented for workup of intermittently flaring right knee pain and uricemia. Uric acid is elevated, plain film imaging is ordered, arthrocentesis is planned, and HLA testing is performed to inform uricemia treatment. Next generation sequencing (NGS) typing reveals the patient carries HLA-B*58:11. Sequence analysis demonstrates the allele’s open reading frame differs from HLA-B*58:01 by a single I194V substitution. Amino acid sequences of peptide binding regions (PBR) encoded by these alleles are identical. Presentation of allopurinol/oxypurinol peptides to T-cells by B*58:01 is the putative mechanism underlying AHS pathogenesis. Identical protein sequence in the PBR of B*58:11 favors similar function. Findings are reported and treatment with allopurinol foregone. Results (if a Case Study enter NA) NA Conclusion High resolution HLA testing is essential to appropriately interpret and report results for disease risk and pharmacogenomics assessments. However, NGS detects rare alleles that have yet to be associated with a disease process. When pathogenesis is thought to be linked to the PBR, rare HLA alleles with identical or similar PBR to disease associated alleles may confer similar risk. In this case, NGS identified PBR similarity between the patient’s allele and an established AHS risk allele. Although B*58:11 has not been shown to be associated with AHS, likely due to low prevalence, the risk was deemed sufficient to select an alternative therapy and potentially prevent a lethal drug reaction.

Cronenberg Adapts (Us to) McLuhan: Watching "Videodrome", Reading "Understanding Media"

This article argues that Videodrome and the film’s novelization can both be said to adapt McLuhan’s account of television in Understanding Media. Cronenberg’s film adopts McLuhan’s style of thought by rendering figurative language as visceral cinematic image; Martin’s novelization, in turn, uses the literary device of ekphrasis to depict the protagonist’s TV-possessed inner world. Videodrome the film and Videodrome the novel express, respectively, the cinematic imaging and the synesthetic verbal description of media as «the extensions of man». The essay concludes that attending to the ways in which both the film and the novel adapt McLuhan’s writing not only attests to the intermedial nature of the interpretive act, but helps delineate the contours of the contemporary media landscape.

Voicing the Border: On Some Spectral Essay Films

Giving prominence to the auditory nature of the border, this article argues for the importance of voice to the epistemological practices of border essay films. By engaging with three relevant case studies—Appunti del passaggio by Maria Iorio and Raphaël Cuomo (2014–2016), Spectres Are Haunting Europe by Maria Kourkouta and Niki Giannari (Fantasmata planiountai pano apo tin Evropi, 2016), and An Asian Ghost Story by Bo Wang (九龍東往事, 2022)—it carries out an acoustemology of spectral border essay films that, to cite Jacques Derrida, speak of the ghost to speak of justice. In so doing, it shows that, through an experimental use of voice, these films perform the border by making it audible. Their experimental approach to make the border “heard” subverts the standard relationship between sound and image in documentary cinema. Simultaneously, it de-forms and re-forms the essay film via postcolonial and feminist appropriations and spectral modifications of the essayist’s translocal, border-crossing voiceover.

Cultural Characteristics of Female Hero Images in Intangible Cultural Heritage Films

In Chinese films with intangible cultural heritage themes, female images are an indispensable presence. Particularly, several renowned female hero figures derived from folklore literature, such as Liu Sanjie, Ashima, and Hua Mulan, stand out as symbols of both traditional Chinese heroines and the cultural zeitgeist. This paper utilizes Roland Barthes' semiotic theory to analyze the characteristics of these three representative intangible cultural heritage-themed folk literature films. By employing text analysis methods, it examines the elements of costume, dialogue, setting, and plot in these films. These symbolic elements elucidate the development of female characters and cultural transformations, revealing how traditional culture is represented and transmitted in modern media. The paper also explores the crucial role and value of women in the preservation and inheritance of intangible cultural heritage, offering suggestions for better shaping the images of female heroes in intangible cultural heritage-themed films.

Eschatology of the Singularity: “Deus ex machina” in the Construction of Film Images of the Future

The mixed assessment by critics and theorists of the deus ex machina artistic device common in popular cinema requires a more thorough study of its dramatic and narrative functions in science fiction films. It is in the construction of film images of the future that this technique is combined with a fantastic assumption, expressing the narrator’s attitude towards artistic narration and becoming an argument in dialogue with the viewer. The study reveals, based on the analysis of empirical material, the multifunctionality of deus ex machina using the example of the development of the theme of technological singularity in cinema. The analysis of films significant for the development of the science fiction (Sci-Fi) genre and the most popular television series among science fiction fans today demonstrates the evolution of the deus ex machina technique. In addition to the trivial function of arbitrary resolution of peripeteia, it acquires various dramatic functions (accelerating or slowing down the rhythm of action, connecting parts of the plot in a large form), obtains the properties of scaling and fragmentation, synchrony and asynchrony with a fantastic assumption, adding complex narrative functions to the toolkit of expressive means, through which the narrator reveals or, on the contrary, conceals his attitude to artistic reality, involving the viewer into the game of probable meanings. The authors of the article come to the conclusion that the theme of technological singularity has been penetrating cinema since its appearance in the work of L. Lumiere and determines, depending on the narrator’s attitude to the topic, the vector of techno-skepticism or techno-optimism in the eschatological dilemma that characterizes the cosmogony of traditional religions. The article is of interest to researchers and film lovers and contributes to the study of artistic and scientific communication.

A three-stage framework for accurate detection of high-speed train body paint film defects

Detecting paint film defects on high-speed train (HST) body is a crucial step towards zero-defect manufacturing (ZDM). The effectiveness of defect detection in industrial environments, however, is significantly impacted by factors such as high reflection noise, weak defect features, small defect size, and various defect scales, resulting in unsatisfactory detection accuracy. To address these challenges, this paper proposes a technical framework for the accurate detection of paint film defects on HST body, encompassing three stages. A reflection detection removal method that takes into account the reflection transition region as well as the preservation of defect features is at first used to reduce reflection noise interference. Then a lightness-weighted adaptive image enhancement algorithm based on the fractional order differentiation is utilized to enhance the features of paint film defects while avoiding the introduction of reflection noise. Finally, an improved YOLOv5 algorithm, incorporating attention mechanism feature extraction and multi-scale feature fusion, is employed to detect and classify paint film defects. Experimental results demonstrate that the proposed framework effectively reduces the reflection in paint film images, and enhances the contrast between paint film defects and the background, with a mean average precision (mAP) for defect detection reaching up to 90.13%. This work serves as a valuable reference for the automated detection of defects arising in the painting process of HST body.

Poetics and Aesthetics, Analog and Digital

This article is the result of a case study based on the methodological procedures of a focus group carried out with Cinema students, in São Paulo, in May 2024. The study selected a sample of six Cinema students, young people with more than half of the course degree already completed, therefore with some knowledge and practice of film production and with some repertoire of appreciation of cinematographic techniques and discourses. The primary purpose of the Study was to investigate whether these students would aesthetically perceive the language resources used in the poetic construction of director of photography Mike Gioulakis in the film Night Shyamalan’s Old. There were two language resources: the use of analogue cameras and celluloid film to capture the film's images. Based on the premise that the majority of students would watch the film on digital devices, there was a possibility that the language resources would not be completely grasped. As the premise turned out to be true, the Study resulted in important findings and even more important questions.

Polarization-insensitive terahertz third-harmonic generation from degenerate pairs of mirror-coupled super-BICs

Resonant nanostructures have emerged as versatile photonic platforms for boosting optical nonlinear responses on a subwavelength scale for their ability to confine intense electromagnetic fields while relaxing the phase-matching requirements. Recent significant advances in this field are associated with the utilization of non-radiative eigenmodes above the light cone, termed bound states in the continuum (BICs), which provide a unique mechanism for light trapping to realize excitation of ultrahigh quality (Q) factor resonances. Nevertheless, the current studies on BICs predominantly focus on symmetry-protected BICs (SP-BICs), whose excitation requires symmetry breaking, and Q factors are limited by fabrication imperfections. Here, we demonstrate a simple and feasible scheme for creating degenerate pairs of mirror-coupled super-BICs by harnessing magnetic dipole resonances coupled to their mirror images in adjacent metal films. Unlike trivial SP-BICs, mirror-coupled BICs showcases the huge enhancement of Q factors and are resilient against fabrication imperfections. By combining mirror-coupled resonance with the engineered radiative loss, we obtain a perfect absorber with near-unity absorption and ultra-narrow bandwidth at a critical coupling condition. Finally, we numerically demonstrate the terahertz (THz) regime, polarization-insensitive highly efficient third-harmonic generation benefiting from the maximum field enhancement localized within the perfect absorber. Our work not only paves the way toward unlocking the full potential of BIC resonance but also promise valuable insights for developing efficient THz optoelectronic devices and metadevices across a wide range of fields.

SPR humidity dynamic monitoring method via PVA sensing membrane thickness variation and image processing techniques

Humidity monitoring is paramount in diverse applications, industrial, and medical applications. Surface Plasmon Resonance (SPR) is an optical detection technique capable of sensing various environmental parameters through changes in reflected optical spectra and has garnered significant attention. Typically, SPR sensing employs a single-point detection strategy with the sample at a fixed concentration to achieve optimal sensitivity, limiting its application in dynamic environmental testing. This study proposes an image-based SPR humidity monitoring method, integrating SPR with image processing, enabling dynamic parameter reconstruction, and achieving high responsiveness. Au-PVA is used as a sensing film. To attain the best sensing film thickness, sensing film thicknesses ranging from 94.0 nm to 243.3 nm were tested. Through optimizing film thickness and image data processing, high precision and dynamic responsiveness were achieved. Experimental results demonstrate a response time of 84 ms and an average relative prediction error of 1.57 % for the sensor. Our research holds significant promise for dynamic and accurate humidity detection.

Thermal-induced bandgap broadening phenomenon in copolymer organic semiconductors

This study elucidates the thermal-induced bandgap broadening (TBB) phenomenon in copolymer organic semiconductors (OSCs). From the perspective of device physics, the diketopyrrolopyrrole-based copolymer was employed as the semiconductor layer to fabricate a back-to-back Schottky junction structure. Characterization through the analysis of I–V curves enables the qualitative exploration of the correlation between bandgap and temperature in copolymer OSCs. Then, technology computer-aided design was utilized to explore the influence of thermal-induced bandgap broadening on the back-to-back Schottky I–V curves. Subsequently, the variable temperature UV-VIS-NIR absorption spectra of the copolymer OSCs were analyzed, providing quantitative evidence of the thermal-induced bandgap broadening phenomenon and confirming its recoverability. Through the research of the Schottky junction and absorption spectra, we verified the consistency of the TBB phenomenon in both the electrical and optical bandgaps. From the scanning electron microscope images of the copolymer OSC films, it is found that the thermal-induced bandgap broadening phenomenon is mainly caused by thermal expansion and increased disorder of copolymer molecules. This study highlights a physical phenomenon of copolymer OSCs that is different from most inorganic semiconductors, and such insight offers a theoretical perspective for the application and thermal stability investigation of copolymer devices under high temperature conditions.

A Comparison of Women's Image in Women's Films in Chinese and Western Cultures from a Female Perspective --Carol and Woman-Demon-Human

In the different cultural backgrounds of China and the West, the trend of feminism and related films is different. The image of women is an important part of Chinese and Western culture and a special product of the times, which is extremely important for the understanding of female subjects and social development. Based on the films Woman-Demon-Human and Carol, this paper aims to explore the survival status of women and the manifestation of feminist awakening in different times from the aspects of feminism, self-consciousness, and gender differences, to show the dilemmas and struggles faced by women in modern China and the West, as well as the impact of gender manifestation on women. Women who can break through the inherent pattern, get rid of the fate of the male gaze, and have independent subjective consciousness are particularly valuable. The American movie Carol, with Carol and Therese as the main characters, tells the story of women with different personalities who have found themselves in life and have the courage to resist the pressure of the world and the oppression of patriarchal society. Woman-Demon-Human, directed by Huang Shuqin, tells the story of Qiuyun, who is obsessed with the art of opera, plays a male role, and dedicates her life to the stage. These two films portray the image of a true woman who can be autonomous and self-controlled, and deserve to be compared and analyzed in detail in terms of feminist awakening.

Finite element analysis of the impact of bone mass and volume of low-density area under tibial plateau on lower limb alignment

To investigate the impact of the bone mass and volume of the low-density area under the tibial plateau on the lower limb force line by finite element analysis, offering mechanical evidence for preventing internal displacement of the lower limb force line in conjunction with knee varus in patients with knee osteoarthritis (KOA) and reducing bone mass under the tibial plateau. A healthy adult was selected as the study subject, and X-ray film and CT imaging data were acquired. Mimics 21.0 software was utilized to reconstruct the complete knee joint model and three models representing low-density areas under the tibial plateau with equal volume but varying shapes. These models were then imported into Solidworks 2023 software for assembly and verification. Five KOA finite element models with 22%, 33%, 44%, 55%, and 66% bone mass reduction in the low-density area under tibial plateau and 5 KOA finite element models with 81%, 90%, 100%, 110%, and 121% times of the low-density area model with 66% bone mass loss were constructed, respectively. Under physiological loading conditions of the human lower limb, the distal ends of the tibia and fibula were fully immobilized. An axial compressive load of 1 860 N, following the lower limb force line, was applied to the primary load-bearing area on the femoral head surface. The maximum stress within the tibial plateau, as well as the maximum displacements of the tibial cortical bone and tibial subchondral bone, were calculated and analyzed using the finite element analysis software Abaqus 2022. Subsequently, predictions regarding the alteration of the lower limb force line were made based on the analysis results. The constructed KOA model accorded with the normal anatomical structure of lower limbs. Under the same boundary conditions and the same load, the maximum stress of the medial tibial plateau, the maximum displacement of the tibial cortical bone and the maximum displacement of the cancellous bone increased along with the gradual decrease of bone mass in the low-density area under the tibial plateau and the gradual increase in the volume of the low-density area under tibial plateau, with significant differences ( P<0.05). The existence of a low-density area under tibial plateau suggests a heightened likelihood of knee varus and inward movement of the lower limb force line. Both the volume and reduction in bone mass of the low-density area serve as critical initiating factors. This information can provide valuable guidance to clinicians in proactively preventing knee varus and averting its occurrence.
