Authors: Caballero Magdalena , de la Fuente Daniel , Pelegrín José A. S. , Rubio Rafael M.
Published: July 2022

We introduce two different ways to establish the concept of infinitesimal position vector field between “infinitesimally nearby” observers in a Galilean spacetime as well as show their mathematical equivalence. We also use this concept to characterize the family of spatially conformally Leibnizian spacetimes.
Lagrangian and Hamiltonian dynamics for probabilities on the statistical bundle
Authors: Chirco Goffredo , Malagò Luigi , Pistone Giovanni
Published: July 2022

We provide an Information-Geometric formulation of accelerated natural gradient on the Riemannian manifold of probability distributions, which is an affine manifold endowed with a dually-flat connection. In a non-parametric formalism, we consider the full set of positive probability functions on a finite sample space, and we provide a specific expression for the tangent and cotangent spaces over the statistical manifold, in terms of a Hilbert bundle structure that we call the Statistical Bundle. In this setting, we compute velocities and accelerations of a one-dimensional statistical model using the canonical dual pair of parallel transports and define a coherent formalism for Lagrangian and Hamiltonian mechanics on the bundle. We show how our formalism provides a consistent framework for accelerated natural gradient dynamics on the probability simplex, paving the way for direct applications in optimization.
An efficient IISH-2D DCNN-based lung nodule classification using CT scan images
Authors: Pandya Mrudang , Jardosh Sunil , Thakkar Amit
Published: July 2022

Lung cancer has been identified as the world’s leading cause of death. Precise detection and testing of lung nodules at an early stage are essential for the diagnosis of lung cancer, therefore, it is one of the best ways to prevent deaths of lung cancer. An automated nodule detection system provides a second opinion to radiologists during early diagnosis. Much existing research uses Deep Convolutional Networks (DCNNs) for lung nodules classification. However, DCNNs normally need careful tuning of hyperparameters to reveal their excellent performance. Although, with the increasing size of state-of-the-art convolutional neural networks, the evaluation cost of the traditional optimization algorithms has become deplorable in most cases. Also, Lung CT scans data have a data imbalance problem inherently. So, to solve those problems, this paper proposes IISH-2D DCNN for lung nodule classification. The proposed methodology consists of pre-processing and classification phases. In the pre-processing phase, the 3D-CT scan slice is converted into a 2D-slice, and then the nodule boundary is extracted by calculation of ROI. After that, the extracted boundary is given as input to the IISH-2D DCNN that classifies the lung nodules. The performance of the proposed methodology is compared to the existing works based on accuracy, sensitivity, and specificity metrics. Thus, the proposed model outperforms existing lung nodule classification methodologies with higher accuracy, sensitivity, and specificity that are 99.8%, 97%, and 99%, respectively. Also, the proposed methodology has fewer errors than the state-of-the-art methods. Hence, the suggested method attains better performance in lung nodule classification and proves to be more effective.

Published: July 2022

This paper studies the influence of corporate performance and governance on the rating of industry competition degrees from 2012 to 2016. This study uses the ordered logit model and focuses on the non-manufacturing and manufacturing industries from the acquisition perspective and evaluates the rating change of industry competition. The results found that Tobin Q, Earnings Per Share, Management Layer Total Annual Salary, and Number of Board Directors impact the rating changes for industry competition. The manufacturing enterprises can improve the value and income by increasing investment when the market is more concentrated. It can expand the size of the board of directors and reduce compensation to improve the governance ability of the management. The corporate performance and governance of manufacturing industries are more competitive than non-manufacturing industries in the monopolized market. The government offers an efficient manufacturing ecosystem, emphasizes governance policies, and reduces M&A taxes helping localization and industry competition.

Published: July 2022

Micro-learning [1], cognitive training, and even memory training [2] are a few examples of applications that have been made easier-to-use and more available with mobile, wearable, and ubiquitous technologies. Many of them are also presented through conversational interfaces. Current systems for learning and training focus on providing prompts via notifications to start the training sessions at times when we are available. They use timebased or activity-based reminders to prompt us to engage in the notified tasks, be it learning a new word or playing a cognition-enhancing game. A key challenge is that a well-timed prompt may not be effective if the user is not cognitively available to engage in the intervention [3]. Prompto [4] is a mobile system that opportunistically provides prompts when users are cognitively available: during moments of lowered cognitive load and emotional arousal; these are likely during calm and idle moments. At these moments, we are possibly more receptive to learning and remembering.
The Impact of Behavioral Similarity on DSS Advice Acceptance
Authors: Campbell Merle , Keil Mark , Boodraj Maheshwar
Published: July 2022

Despite the many advantages that decision support systems (DSSs) provide to decision makers, acceptance of advice from these systems has remained relatively low. In this study, we leverage theoretical insights from the literature to build a DSS that is behaviorally similar to its user, with the aim of increasing acceptance of DSS advice. To test whether users would be more accepting of advice from a behaviorally-similar DSS, we conducted a field experiment in a complex semi-structured decision context. The results of our experiment provide empirical evidence that a behaviorally-similar DSS can increase acceptance of advice in semi-structured decision-making contexts.

Published: July 2022

For the first time, this research focuses on the inexpensive technique of synthesis of Cu2In2O5 thin films using intermixing of Cu and In layers, deposited using radio frequency (RF) magnetron sputtering technique. Further, structural, morphological, and optical characterization of Cu2In2O5 thin films have been carried out. The layered films were sputtered using Cu and In targets. The layered structure was subjected to post-deposition annealing at temperatures varying from 700 °C to 1000 °C in a constant oxygen ambiance for five hours. Decomposition of the single-phase Cu2In2O5 takes place at 1000 °C, resulting in the appearance of CuO, In2O3, and Cu2O as decomposition products. Descriptive analysis of the formation of the aforementioned products have been included. However, single-phase Cu2In2O5 thin films were obtained at a post-annealing temperature of 900 °C. The oxidation states of In and Cu have been studied through XPS analysis. Full width half maximum (FWHM), peak positions, satellite peak positions, and their respective binding energies have been elucidated through XPS analysis. An increase in the grain size from 36.8 nm to 115.8 nm with an increase in the annealing temperature from 700 °C to 1000 °C, was noticed from the FESEM images. Optical studies were performed on all the annealed films in the 200–2000 nm wavelength range. The bandgap was in the range of 2.88 to 3.46 eV for the films annealed between 700 °C to 900 °C. The refractive index of the single-phase Cu2In2O5 thin film was obtained to be 1.51.

Published: July 2022

The transcription factor Wilms’ tumor 1 (WT1) is involved in development, tissue homeostasis, and disease. However, the exact roles and the mechanisms of WT1 in renal carcinoma are not well understood. Therefore, in this study, we evaluated the ability of WT1 to block proliferation in renal carcinoma cells in vitro. Experimental analysis showed that WT1 overexpression inhibited the proliferation of renal carcinoma A498 cells and promoted arrest at the G2/M checkpoint. RNA‐Seq identified differentially expressed genes, including IL‐24, related to both the cell proliferation and the cell cycle. WT1 overexpression upregulated IL‐24 expression, and IL‐24 overexpression induced G2/M arrest. ChIP‐Seq identified JUN as a direct target of WT1 in A498 cells, in which positive regulation was shown by RT‐qPCR. It has been shown that the transcription factor JUN can regulate IL‐24 expression, and therefore, we hypothesize that WT1 might regulate the IL‐24 through JUN. Furthermore, analysis based on TCGA datasets showed that the expression of WT1‐regulated genes, including TXNIP and GADD45A, was significantly correlated with the stage and histological grade of tumors, with high levels linked to favorable prognoses. Our results demonstrated that the overexpression of WT1 upregulates IL‐24, leading to G2/M checkpoint arrest to reduce proliferation. These results indicate that regulation of IL‐24 by WT1 inhibits proliferation and may represent a potential target for treating renal carcinoma.
The Function of Remote Monitoring System of a Robot Inverter Based on PLC and Cloud Platform
Authors: Yu Mengqi
Published: July 2022

In order to improve the communication efficiency of the CAN bus application layer communication protocol of the inverter network monitoring system, this paper proposes a TTCAN scheduling optimization algorithm for the robot inverter remote monitoring system based on PLC and cloud platform. According to the analysis of the communication requirements of the frequency converter monitoring system, this paper designs the application layer protocol of the nodes in the system and establishes the system scheduling matrix. The time triggered can bus protocol (TTCAN) combines the event triggered mechanism with the time triggered mechanism. The hybrid scheduling strategy is used to optimize the system matrix of TTCAN; that is, the hybrid particle swarm optimization algorithm is used for periodic messages. For nonperiodic messages, uniform scheduling strategy and dynamic scheduling algorithm are adopted. The simulation is carried out by MATLAB tools. The simulation results show that the sum of partial minimum transmission time is 1928 and there are multiple optimal individuals through the hybrid particle swarm optimization algorithm. Compared with the traditional genetic algorithm and single particle swarm optimization algorithm, the hybrid algorithm is better than the traditional genetic algorithm and particle swarm optimization algorithm in terms of iteration times and average fitness value. In conclusion, the optimized TTCAN protocol improves the real-time performance, reliability, and bandwidth utilization of the communication network.

Authors: Alsaeedi Hussein A. , Alhegami Ahmed S.
Published: July 2022

Frequent itemset mining is the most important step of association rule mining. It plays a very important role in incremental data environments. The massive volume of data creates an imminent need to design incremental algorithms for the maximal frequent itemset mining in order to handle incremental data over time. In this study, we propose an incremental maximal frequent itemset mining algorithms that integrate subjective interestingness criterion during the process of mining. The proposed framework is designed to deal with incremental data, which usually come at different times. It extends FP‐Max algorithm, which is based on FP‐Growth method by pushing interesting measures during maximal frequent itemset mining, and performs dynamic and early pruning to leave uninteresting frequent itemsets in order to avoid uninteresting rule generation. The framework was implemented and tested on public databases, and the results found are promising.

Published: July 2022

To analyze the application value of CT-enhanced scanning based on artificial intelligence algorithm in the diagnosis of gastric cancer and gastric lymphoma, the CT images of 80 patients with Borrmann type IV gastric cancer or primary gastric lymphoma diagnosed by endoscopic pathology were retrospectively collected. Meanwhile, a lymph node recognition algorithm based on OTSU threshold segmentation was proposed for CT image processing. The results showed that the missed diagnosis rate of suspected lymph nodes and the missed lymph node detection rate of this algorithm were substantially lower than those of other algorithms (

P

). The probability of gastric wall motility disappearance, perigastric fat infiltration, and type A enhancement pattern in the Borrmann type IV gastric cancer group was higher than that in the gastric lymphoma group, with remarkable differences (

P

). In addition, 5the sensitivity (83.17%), specificity (95.52%), and accuracy (93.08%) of the combined detection of the three CT signs (stomach wall motility, perigastric fat infiltration, and enhancement mode) were substantially improved compared with those of a single sign (

P
<
0.05

). To sum up, the lymph node recognition algorithm based on OTSU threshold segmentation had better performance in detecting gastric lymph nodes than traditional algorithms. The CT image characteristics of gastric wall motility, perigastric fat infiltration, and enhancement pattern based on artificial intelligence algorithms were effective indicators for distinguishing gastric cancer and gastric lymphoma.

Authors: Xu Lanjuan , An Tingting , Li Chengjian , Shi Xin , Yang Bo
Published: July 2022

Objective. To assess the effect of adding coagulation indices to the currently existing prognostic prediction models of traumatic brain injury (TBI) in the prediction of outcome. Methods. A total of 210 TBI patients from 2017 to 2019 and 131 TBI patients in 2020 were selected for development and internal verification of the new model. The primary outcomes include death at 14 days and Glasgow Outcome Score (GOS) at 6 months. The performance of each model is evaluated by means of discrimination (area under the curve (AUC)), calibration (Hosmer-Lemeshow (H-L) goodness-of-fit test), and precision (Brier score). Results. The IMPACT Core model showed better prediction ability than the CRASH Basic model. Adding one coagulation index at a time to the IMPACT Core model, the new combined models IMPACT Core+FIB and IMPACT Core+APTT are optimal for the 6-month unfavorable outcome and 6-month mortality, respectively (AUC, 0.830 and 0.878). The new models were built based on the regression coefficients of the models. Internal verification indicated that for the prediction of 6-month unfavorable outcome and 6-month mortality, both the IMPACT Core+FIB model and the IMPACT Core+APTT model show better discrimination (AUC, 0.823 vs. 0.818 and 0.853 vs. 0.837), better calibration (HL,

) and higher precision (Brier score, 0.148 vs. 0.141 and 0.147 vs. 0.164), respectively, than the original models. Conclusion. Our research shows that the combination of the traumatic brain injury prognostic models and coagulation indices can improve the 6-month outcome prediction of patients with TBI.

Natural colorants have emanated as a significant substitute to highly toxic synthetic dyes. The present study highlights the dyeing efficiency of violet pigment produced from Chromobacterium violaceum PDF23. A halophilic bacterium C. violaceum PDF23 produce violet pigments were isolated from the Great Salt Lake situated in Chennai, India. Based on morphology and 16S rRNA gene sequencing, a halophilic bacterium was identified as C. violaceum PDF23. The violet dye from C. violaceum PDF23 exhibited antimicrobial efficacy against S. aureus, B. subtilis, E. coli, P. aeruginosa, and C. albicans. The violet pigment exhibited radical scavenging potential with IC50 value of 14.40 μg/mL. The dye ability of colorant was evaluated using mordants on two distinct fabrics, i.e., silk satin and cotton, and colorfastness measurements were recorded. The CIE L∗a∗b∗ qualities of the dyed fabrics were assessed, as well as their colorfastness quality. The current research findings suggest that violet pigment has potent antimicrobial and antioxidant activity and it could be used as alternative to synthetic dye in the textile industry.
mTOR Modulates the Endoplasmic Reticulum Stress-Induced CD4+ T Cell Apoptosis Mediated by ROS in Septic Immunosuppression
Authors: Wang Hao , Chen Jianwei , Bai Guangxu , Han Wen , Guo Ran , Cui Na
Published: July 2022

Introduction. When sepsis attacks the body, the excessive reactive oxygen species (ROS) production can result to endoplasmic reticulum stress (ERS) and eventually cause lymphocyte apoptosis. The mammalian target of rapamycin (mTOR) is essential for regulating lymphocyte apoptosis; we hypothesized that it mediates CD4+ T cell apoptosis during ROS-related ERS. Method. We, respectively, used ROS and ERS blockers to intervene septic mice and then detected ERS protein expression levels to verify the relationship between them. Additionally, we constructed T cell-specific mTOR and TSC1 gene knockout mice to determine the role of mTOR in ROS-mediated, ERS-induced CD4+ T cell apoptosis. Results. Blocking ROS significantly suppressed the CD4+ T cell apoptosis associated with the reduction in ERS, as revealed by lower levels of GRP78 and CHOP. ERS rapidly induced mTOR activation, leading to the induction of CD4+ T cell apoptosis. However, mTOR knockout mice displayed reduced expression of apoptotic proteins and less ER vesiculation and expansion than what was observed in the wild-type sepsis controls. Conclusion. By working to alleviate ROS-mediated, ERS-induced CD4+ T cell apoptosis, the mTOR pathway is vital for CD4+ T cell survival in sepsis mouse model.

Published: July 2022

Intervertebral disc degeneration (IDD) is a chronic progressive condition mainly caused by excessive inflammatory cytokines. Berberine (BBR) exerts anti‐inflammatory effect on diseases and protective effect against IDD. However, the mechanism is not uncertain. This study is aimed at investigating the molecular mechanism of BBR on IDD. Nucleus pulposus (NP) cells were treated with BBR at different concentrations. The IDD rat model was established by acupuncture. The effect of BBR on interleukin‐ (IL‐) 1β‐induced cell proliferation was measured by CCK‐8 assay and BrdU staining. The role of BBR in IL‐1β‐induced apoptosis, autophagy repression, and extracellular matrix (ECM) degradation was measured by Annexin/PI staining, immunofluorescence, and immunoblot. The effect of BBR on IDD was investigated in rat. Our findings showed that BBR restored cell growth and attenuated apoptosis in IL‐1β‐induced NP cells. BBR also prevented the IL‐1β‐induced ECM degradation through regulating ECM‐related enzymes and factors. Additionally, BBR significantly activated autophagy repressed by IL‐1β. Autophagy stimulated by BBR was diminished by the inhibition of the AMPK/mTOR/Ulk1 signaling pathway. In vivo study also showed BBR attenuated intervertebral disc degeneration. BBR could attenuate NP cells apoptosis and ECM degradation induced by IL‐1β through autophagy by the AMPK/mTOR/Ulk1 pathway. This study suggests BBR might function as an AMPK activator to alleviate IDD progression.

Aim. To analyze the distribution and characteristics of infraocclusion among Arabian children in primary dentition and its associated dental anomalies. Methods. A radiographic analysis was performed retrospectively using digital panoramic radiographs of children attending the pediatric dental clinic of College of Dentistry, Majmaah University, Saudi Arabia, from January 2019 to May 2021. The panoramic radiographs were analyzed to assess the distribution and characteristics of infraocclusion and its associated dental anomalies. Descriptive statistics were used for comparisons using SPSS version 21.0 (IBM Corp., Armonk, N.Y., USA). The chi‐square test was used to compare percentages. Results. Among the study population (542), only 40 children reported infraocclusion of 65 primary molars. Infraocclusion was common in males (90%) and very frequent in the mandibular arch (n = 48 teeth). In the primary dentition, unilateral infraocclusion (62.5%) was very frequent than bilateral presence (37.5%). Single molars were involved in 50% of the patients, while two, three, and four molars were involved in 42.5%, 2.5%, and 5% of cases. The mandibular second primary molar was frequently affected with infraocclusion, while the maxillary first primary molar was less commonly affected. In the mandibular arch, the second primary molar (28, 58%) was more commonly affected with infraocclusion than the mandibular first primary molars and maxillary primary and secondary molars (p < 0.05). The majority of the infraoccluded molars were mild (75%), followed by moderate (23.5%) and severe (1.5%). Hypodontia (12.5%) is frequently associated with infraocclusion, followed by supernumerary teeth (5%) and radix entomolaris of the first permanent mandibular molars (5%). Infraocclusion was more in the second primary molar mandibular arch, while in the maxillary arch, the first primary molars were commonly affected (p > 0.05). Conclusion. In Arabian children, infraocclusion was commonly observed in mandibular second primary molars. Unilateral infraocclusion is a mild type of infraocclusion frequent in Arabian children. Numerical anomalies such as hypodontia and supernumerary teeth are associated with infraocclusion.

Published: July 2022

This research concentrated on material characteristics such as tensile property (TS) and hardness (HV) for AA‐5083 manufactured using the stir casting (SC) process. The reinforcing elements silicon carbide (SiC‐7.5%) and flyash (FA‐5%) in the form of powders will be added to Al alloy to improve the characteristics of composites. Response surface methodology (RSM) was a scientific technique to make optimizing task at stir casting parameters. As per central composite design (CCD), 20 samples (L1‐L20) were fabricated at a variation of factors such as stirrer speed (A) 350‐550 rpm, stir time (B) 15‐35 min, and stir temperature (C) 750‐950°C. The result presented that best TS and HV exhibited at experiments L5 (A2‐450 rpm, B1‐15min, and C1‐750°C) and L6 (A1‐350 rpm, B1‐15min, and C1‐750°C). Design expert software (DES) is one of the optimization tools that employed to determine analysis of variance (ANOVA) and the best optimal parameter levels of SC. ANOVA helped to check contribution of SC factors on TS and HV, and it was noticed that mechanical properties were improved with increasing stir speed and stir time but it was reduced with rising of temperature.

Simulation results show: The vignetting correction time of the combined building facade panoramic image using the vignetting correction method of surface fitting, compared with the common vignetting correction method, the vignetting correction time of the combined building facade panoramic image is shorter, and it is stable at about 5 seconds. Conclusion: The proposed method can effectively correct the vignetting of the combined building facade panoramic image, and the gray distribution of the corrected image is uniform, which shortens the image vignetting correction time.
Reconstruction of New Media Art Ecology Based on Intelligent Technology Environment
Authors: Xi Mengying
Published: July 2022

With the rapid development of modern multimedia technology and Internet technology, the traditional media in people’s daily life, including newspapers, magazines, radio, and television, are far less timely and extensive than the new media that use the Internet to spread, such as today’s headlines, microblog, TikTok, and NetEase News. In the process of its own development, Internet new media has gradually derived new media art, which is different from traditional art forms, with the mixture of sound, light, and electricity as the form of expression and the Internet as the media. The wide spread of new media art depends very much on the development of the Internet. In the early stage, the audience of new media is not wide, such as Tianya Forum and Sina blog. It is only for information exchange and communication with people who use the computer Internet. At the same time, the content shared is limited to words and pictures. When the computer Internet began to popularize and the mobile network terminal began to develop, new media art immediately sprouted. Starting from instant messaging, Tencent QQ integrates the strengths of all kinds of new media and promotes the further development of new media art. Standing at the juncture of 2022, after more than ten years of continuous innovation and development, the expression terminal has come from the computer to the mobile phone we use every day. The media has quickly entered the 5 g network from 2G and 3G networks, and the communication path and time have been quite flexible. In addition, AI (artificial intelligence) and other intelligent technologies have begun to enter people’s daily life. The combination of intelligent technology and new media art has brought new media art into another period of transformation and sublimation. This paper will discuss that in the current environment where intelligent technology has begun to be popularized in people’s daily life, new media art achieves the result of ecological reconstruction by innovating and deepening its own characteristics in combination with intelligent technology.

Published: July 2022

Nerves are a component of the tumor microenvironment contributing to cancer progression, but the role of cells from nerves in facilitating cancer invasion remains poorly understood. Here we show that Schwann cells (SC) activated by cancer cells collectively function as tumor-activated Schwann cell tracks (TAST) that promote cancer cell migration and invasion. Nonmyelinating SCs form TASTs and have cell gene expression signatures that correlate with diminished survival in patients with pancreatic ductal adenocarcinoma. In TASTs, dynamic SCs form tracks that serve as cancer pathways and apply forces on cancer cells to enhance cancer motility. These SCs are activated by c-Jun, analogous to their reprogramming during nerve repair. This study reveals a mechanism of cancer cell invasion that co-opts a wound repair process and exploits the ability of SCs to collectively organize into tracks. These findings establish a novel paradigm of how cancer cells spread and reveal therapeutic opportunities.

Significance:

How the tumor microenvironment participates in pancreatic cancer progression is not fully understood. Here, we show that SCs are activated by cancer cells and collectively organize into tracks that dynamically enable cancer invasion in a c-Jun–dependent manner.

Impact of Vessel Narrowing and Changes in Blood Flow on the Development of Ischemia in Cervical Arterial Dissection Using Quantitative Magnetic Resonance Angiography
Authors: McGuire Laura Stone , Ryoo James S. , Hanjani Sepideh Amin , Atwal Gursant , Charbel Fady T. , Alaraj Ali
Published: July 2022

Background

Up to 3% of all ischemic strokes are secondary to dissections; however, cerebral hemodynamic patterns in cervical arterial dissection and their association with cerebral ischemia are unknown. This study represents the first to assess blood flow using quantitative magnetic resonance angiography in patients with cervical arterial dissection and their presentation with ischemia.

Methods

Retrospective chart review was completed in patients with cervical arterial dissection between 2009 and 2019. Inclusion criteria were adults with dissection of internal carotid artery or vertebral artery who underwent baseline magnetic resonance imaging (MRI) and quantitative magnetic resonance angiography. Cases were reviewed for presentation, management, and imaging findings. Flow index was calculated using ipsilateral vessel flow divided by contralateral flow.

Results

A total of 37 patients with a mean age of 45.95±11.95 years were included. Of the patients, 19 (51.2%) had internal carotid artery dissections, 17 (45.9%) with vertebral artery dissections, and 1 with both. Patients with ischemia on MRI demonstrated lower flow in the ipsilateral vessel when compared with those patients without ischemia (
P
=0.003). Using the flow index in receiver operating characteristic analysis to predict ischemia on MRI yielded an area under the curve of 0.833 (
P
=0.002); receiver operating characteristic analysis of the percent of total flow for ischemia on MRI found an area under the curve of 0.895 (
P
=0.000), and receiver operating characteristic analysis of percent vessel narrowing calculated an area under the curve of 0.887 (
P
=0.000). Multivariate analysis identified vessel narrowing as significantly associated with ischemia on MRI (
P
=0.03).

Conclusion

This study represents the first to evaluate blood flow in patients with cervical arterial dissection using quantitative magnetic resonance angiography and its relationship with cerebral ischemia. Patients with lower flow as a result of dissection appear to be at higher risk of ischemia on presentation, emphasizing the role of hemodynamics in underlying pathophysiology, and vessel narrowing appears paramount in the association with developing ischemia.

Authors: Sato Maki , McKinney Jonathan
Published: July 2022

Dualisms are pervasive. The divisions between the rational mind, the physical body, and the external natural world have set the stage for the successes and failures of contemporary cognitive science and artificial intelligence.1 Advanced machine learning (ML) and artificial intelligence (AI) systems have been developed to draw art and compose music. Many take these facts as calls for a radical shift in our values and turn to questions about AI ethics, rights, and personhood. While the discussion of agency and rights is not wrong in principle, it is a form of misdirection in the current circumstances. Questions about an artificial agency can only come after a genuine reconciliation of human interactivity, creativity, and embodiment. This kind of challenge has both moral and theoretical force. In this article, the authors intend to contribute to embodied and enactive approaches to AI by exploring the interactive and contingent dimensions of machines through the lens of Japanese philosophy. One important takeaway from this project is that AI/ML systems should be recognized as powerful tools or instruments rather than as agents themselves.
Trans-cultural and Intercultural Humanism As a Response to the “Clash of Civilizations”
Authors: Turki Mohamed
Published: July 2022

In the early 1990s, after the fall of the Berlin Wall and with the easing of East- West tensions, Samuel Huntington presented his theory of a “clash of civilizations.” He announced that conflicts between ideologies had come to an end and were to be replaced by a new kind of confrontation, this time between cultures and religions.

This essay attempts to show how misled Huntington’s thesis can be by referring to forms of humanism from Africa as well as to some ideas developed in Arabian-Islamic philosophy. In the early 1930s, African intellectuals such as Léopold Sédar Senghor or Aimé Césaire already tried to oppose their own conception of humanism to Western individualistic humanism. The distinction can be found in the concept of Ubuntu, or “African humanism,” which incorporates notions of respect for the other, collective responsibility and solidarity. The Arab-Islamic world has also had similar concerns from an early stage. Its heritage from classical Greek philosophy, which placed human being at the centre of its thinking and ethical acting, came indeed under the significant influence of Islamic values, such as equality, fraternity and the community.

Thus the essay offers an alternative to Huntington’s post-modern model of “clash of civilizations” beyond the frontiers set by Western humanism and that is more relevant to our current globalising world – a new trans- and intercultural humanism that favours the ways human beings can relate to each other as persons regardless of race, culture and religion. Human dignity and respect for the “other,” including the environment, are therefore central to this new humanism.
Ambiguity, Diversity and an Ethics of Understanding:
Authors: Kopf Gereon
Published: July 2022

The world in the global age is characterized by a diversity of cultures, philosophies, religious traditions, and by a political landscape that increasingly features a multiplicity of powers or at least sides. Thus, an increasing amount of voices suggests the inevitability of multiculturalism, “intercultural philosophy,” religious dialogue, and political multilateralism. At the same time, however, the step from the fact of diversity to pluralism, that is the belief that diversity is a value, is frequently questioned. What is missing in this debate on pluralism, however, is a genuine philosophy of diversity, that is, a philosophy that takes into account the fact of diversity without succumbing to either particularism or universalism. This essay will try to examine the metaphysical conditions for diversity in order to suggest a philosophical position that takes seriously the diversity of cultures, traditions, and positions, without denying their individual particularities and idiosyncracies, on the one hand, and yet allows the theorist to envision a philosophy that does justice to the postmodern predicament, on the other.
The Sceptic Pilgrim: Seeking Intercultural and Interdisciplinary Patterns In the Philosophy of Creativity
Authors: Ovens Martin
Published: July 2022

This essay considers a potential linkage between skepsis and the engendering of creativity. It explores and contests the possibility of a dialogical evolution of an intercultural scepticism, in particular a mode of skepsis conceived as a viable, productive way of life. It reflects on the conditions that encourage the development of a sceptical sensibility with reference to Sextus Empiricus, and then depicts an intercultural unfolding of the “sceptic ego” via reference to encounters with traditions such as Daoism and Romanticism. The result is a scepticism culminating in a disposition toward creativity and empathetic, interdisciplinary enquiry. Intercultural skepsis emerges as the possibility of manifesting as a “philosophy of creativity” that must demonstrate its usefulness, and justify itself, by producing concrete, communicable, worthwhile results.
Translating Across Cultures:
Authors: Raveh Daniel
Published: July 2022

The paper offers a philosophical reflection upon the film Ghajini which was directed by Ajith Rahul Murugadoss in 2008. The film is an Indian remake/translation/transcreation of Christopher Nolan’s Memento (2000). Through Ghajini, I attempt to explore the reversible migration between spaces such as forgetfulness and memory, moment and sequence, inwardness (or consciousness) and externality (or the world). The paper creates an intercultural dialogue about self-identity and the materials of which it is made, a theme touched upon and developed in both movies, Ghajini and Memento, each in their own way. Special attention is given to the activity of translation, with its possibilities and impossibilities, as the breeding-ground of every dialogic encounter. In my philosophical collage I draw on classical texts such as Patañjali’s Yogasūtra as well as modern interpretations such as Luce Irigaray’s Entre Orient et Occident.
America against China
Authors: Botz-Bornstein Thorsten
Published: July 2022

This essay reflects on Chinese and American hyperrealism and its effect on the self-perceptions and cultural identities of both countries. Hyperreality is a condition whereby it is impossible to distinguish reality from fantasy. Such a condition is common in technologically advanced cultures where virtual reality has made possible the endless reproductions of fundamentally empty appearances. It is however also possible to speak of hyperreality in terms of “culture” or “civilization.” As a first example, China produces a hyperrealist version of its culture in ways that are peculiar to the Confucian treatment of history. As a second example, hyperrealism can be seen in American civilization, which has often been described by some as a materialized utopia excelling in simulations such as Disneyland or Las Vegas and that permeates through large parts of American life like an underlying structure.

The mythical and pseudo-historical past upon which many Chinese philosophical discourses are built has arguably led to a quasi-virtual timelessness whose effects remain significant in China’s contemporary political life. At the same time, American civilization consists – viewed from a certain angle – in an aseptic, dishistoricized culture that authors such as Jean Baudrillard have described in terms of “hyperreality.”
I and Thou
Authors: Biswas Goutam
Published: July 2022

This essay attempts to outline a philosophical anthropology with dialogicality as its key concept. It argues that it is impossible to explicate this concept with any bias toward the ontological primacy of either the subject or the knowable object. The essay develops from the philosophy of Martin Buber who vindicated the need for subject-object binarism to be superseded by a relational ontology of human existence, that is, a space between the dialoguing I and Thou. From this point of view, different sectors of human studies – including those involving politics or socio-political crafting of human states of affairs – must be approached according to their unique dimension. The essay’s envisioning of knowledge of humans by human being beyond any subject-object dichotomy implies a new perspective of self-other relationship whereby the phenomenological notion of intentionality is apprehended in its dialogical mode.
Dialogue with a Devious Divinity: Sovereignty, Kinship, and Kṛṣṇa’s Ethics in the Mahābhārata
Authors: Proferes Theodore
Published: July 2022

The character of Lord Kṛṣṇa has long confounded students of the Sanskrit epic, the Mahābhārata. In addition to the problem of his divinity, many have questioned the nature of Kṛṣṇa’s ethical standpoint, some presenting him as a being who transcends questions of right and wrong, others depicting him as unconcerned with the ethical limitations of human beings. This paper explores these issues through a close examination of Kṛṣṇa’s first significant dialogue with Yudhiṣṭḥira in the epic, in which he seeks to convince Yudhiṣṭhira to slay the autocrat of Magadha, Jarāsaṃdha. It is argued that, through this dialogue, Kṛṣṇa reveals himself to be neither ethically transcendent nor amoral; rather, he is deeply committed to a traditional system of ethics according to which defense of one’s kin group is the highest value and justifies all action.
Freak, not Sage: An Exploration into Freakishness in Modern Jewish Culture
Authors: Hezser Catherine
Published: July 2022

The images of the clown and the freak and representations of the grotesque body are recurrent motifs in modern Jewish literature, film, art, theatre and dance. Kafka’s novella Metamorphosis is an early prototype of the changeling who leaves conventional human appearance behind and is gradually transformed into an insect-like creature. The story served as a prototype for Woody Allen’s film Zelig, in which the main protagonist adopts a variety of different personas, amongst them a Nazi in the Third Reich. The theme of morphing into a freak, clown, or grotesque body reappears in various forms in contemporary Jewish culture and art: The American Jewish writer Philip Roth declared in the 1960s that he was not a Jewish sage but a Jewish freak. Freakishness, clowns, and the circus have a subversive potential: they constitute a digression from what is considered normal appearance and behaviour and play with presumptions, expectations, and social values. A study of this subject reveals the constant dialogue between religion and culture as far as Judaism is concerned.
The Limits of the Dialogical: Thoughts on Muslim Patterns of In- and Exclusion
Authors: Hartung Jan-Peter
Published: July 2022

In a time of heightened demand for inter-religious, or inter-faith dialogue, especially from official political agents, a sound assessment of the possibilities and limitations of such endeavour seems imperative. Consequently, in the present paper serious doubts into the prospect of dialogue based on religious beliefs are raised. This is done, firstly, by criticising the rather optimistic discourse ethical concepts of Karl-Otto Apel and Jürgen Habermas with the intervention of the analytical philosophy of Ludwig Wittgenstein. Secondly, the philosophical improbability of in fact any kind of faith-based dialogue is illustrated by a survey of the Muslim discourse on inclusion into, and exclusion from their idealised discursive community, that is, the Muslim umma. This example shows vividly the difficulties, if not the impossibility, to engage in a rational and, thus, productive, debate on faith premises already within a self-perceived single and unified religious tradition, leaving alone traditions rooted in fundamentally different axiomatic propositions.
