Sandpiper optimization with hybrid deep learning model for blockchain-assisted intrusion detection in iot environment

Intrusion detection in the Internet of Things (IoTs) is a vital unit of IoT safety. IoT devices face diverse kinds of attacks, and intrusion detection systems (IDSs) play a significant role in detecting and responding to these threats. A typical IDS solution can be utilized from the IoT networks for monitoring traffic, device behaviour, and system logs for signs of intrusion or abnormal movement. Deep learning (DL) approaches are exposed to promise in enhancing the accuracy and effectiveness of IDS for IoT devices. Blockchain (BC) aided intrusion detection from IoT platforms provides many benefits, including better data integrity, transparency, and resistance to tampering. This paper projects a novel sandpiper optimizer with hybrid deep learning-based intrusion detection (SPOHDL-ID) from the BC-assisted IoT platform. The key contribution of the SPOHDL-ID model is to accomplish security via the intrusion detection and classification process from the IoT platform. In this case, the BC technology can be used for a secure data-sharing process. In the presented SPOHDL-ID technique, the selection of features from the network traffic data takes place using the SPO model. Besides, the SPOHDL-ID technique employs the HDL model for intrusion detection, which involves the design of a convolutional neural network with a stacked autoencoder (CNN-SAE) model. The beetle search optimizer algorithm (BSOA) method is used for the hyperparameter tuning procedure to increase the recognition outcomes of the CNN-SAE technique. An extensive simulation outcome is created to exhibit a better solution to the SPOHDL-ID method. The experimental validation of the SPOHDL-ID method portrayed a superior accuracy value of 99.59 % and 99.54 % over recent techniques under the ToN-IoT and CICIDS-2017 datasets.

Polo-like kinase 2 targeting as novel strategy to sensitize mutant p53-expressing tumor cells to anticancer treatments.

Polo-like kinase 2 (Plk2) belongs to a family of serine/threonine kinases, and it is involved in tumorigenesis of diverse kind of tissues. We previously reported that Plk2 gene was a transcriptional target of the mutant p53/NF-Y oncogenic complex. Plk2 protein can bind to and phosphorylate mutant p53 triggering an oncogenic autoregulatory feedback loop involved in cancer cell proliferation and chemoresistance. In this study, we aimed to assess whether the specific inhibition of Plk2 kinase activity by the selective TC-S 7005 inhibitor could decrease cell proliferation and migration inhibiting mutant p53 phosphorylation, thus disarming its oncogenic potential. We found that the Plk2 inhibitor treatment sensitized the cells to the irradiation and chemotherapy drugs, thereby overcoming the mutant p53-dependent chemoresistance. Taken together, we provided results that Plk2 could be considered a tractable pharmacological target for cancers expressing mutant p53 proteins. The combined treatment with conventional chemotherapeutic drugs and Plk2 inhibitors may represent a new candidate intervention approach, which may be considered for improving tumor cell sensitivity to DNA damaging drugs. KEY MESSAGES : Missense mutations are present in the TP53 gene in about half of all human cancers and correlate with poor patient outcome. Mutant p53 proteins exert gain of function (GOF) activities in tumor cells such as increased proliferation, genomic instability and resistance to therapies. Polo-like kinase 2 (PLK2) binds and phosphorylates mutant p53 protein strengthening its GOF activities. Pharmacologically targeting PLK2 weakens mutant p53 proteins and sensitizes tumor cells to therapeutic treatments.

The research dealt with the topic of (employing technology in the design of digital advertising and its creative representations in the products of art education students). The research contained four chapters. The first chapter dealt with: the methodological framework of the research, represented by the research problem that was revealed in the following question: How has technology contributed to employment in the design of digital advertising? They have no role in enriching the creative process and are represented in their artistic productions. The researcher determined the limits of the research, which were represented by the products of the students of the Department of Art Education - First Stage / College of Fine Arts/ University of Baghdad for the academic year (2020-2021), and then the researcher moved to the second semester, which included two sections. The title of the first section was employing technology artistically for advertising, and the section included the second is the creative process and aesthetic standards in the artistic achievement, and the researcher extracted a number of indicators that resulted from the theoretical framework: 1. The use of digital technical methods in employing shapes by following the technique of assembling and composing photographs, and generating a main rhythm between images and color values, served the functional aspect and the creative process of the advertising poster. 2. The computer showed a kind of diversity and excitement in the use of letters and their formal formulation in the design space. Among the most important conclusions is that the use of digital technology in the field of art education for practical academic subjects has given students the ability to diversify the styles of artistic production and facilitate the procedures used in producing these artistic works.

Laissez-Passer: Papering over the French Revolutionary Past

Abstract In France, the last decade of the eighteenth century saw an explosion in papers of diverse kinds, put to new political uses. However, in the aftermath of the French Revolution, paper was also instrumentalised to articulate histories of revolutionary participation, as well as changing ideas about revolutionary identification. Some of these were coded as virtuous: paper objects found a place at the heart of sentimental accounts of personal sacrifice, such as that of prison warder Joseph Cange. Conversely, paper was central to claims for culpability or reparation—most strikingly, assorted papers were mobilised as defence against recrimination for involvement in regicide, as discussed here in relation to printmaker and politician Antoine-Louis-François Sergent-Marceau. This essay considers how the apparent abundance that characterised the period’s paper ecology, along with new attitudes toward paper’s proliferation, preservation and disposal, bore the imprint of political justification, evasion and historical revisionism—all framed by the need to ‘pass’ as post-revolutionary.

Examining Diversity and Equity in LIS Education: A Syllabus to Reading List Analysis

To determine how effectively the Master of Library and Information Science curriculum at Indiana University - Indianapolis is addressing the new ALA core competency related to social justice, we analyzed all the course syllabi and are now in the process of analyzing all course readings, using various text analysis methods. We found the initial review of syllabi to lack the level of granularity that would have revealed the different kinds of diversity and equity issues in the curriculum. Additionally, courses we know for certain that covered topics related to social justice, the syllabus alone indicated otherwise. For these reasons, we decided to examine the readings that comprised the entire curriculum. With 68 courses and over 3000 readings to date, gathering the data for analysis has taken several months of time. Metadata and PDFs of course readings were stored in Zotero and extracted from there for analysis. Terminology, as identified from the study that examined all ALA-accredited LIS program course descriptions, will be used to frame the textual analysis (Dill, Grote, & Hardin, 2023). We will present the topics and trends identified through bibliometric analysis, topic modeling, and visual analysis of the citation data. This analysis will shed light on areas of strength and for improvement within curriculum with the goal of preparing students to effectively work in socially just library environments.

Review on chemical mechanical polishing for atomic surfaces using advanced rare earth abrasives

Abstract During the past decades, high-performance devices and setups have been widely used in the fields of precision optics, semiconductors, microelectronics, biomedicine, optoelectronics and aerospace. It is a challenge to achieve ultralow surface roughness free of damages. Due to the unique physicochemical properties of rare earths, ceria has garnered great progresses for atomic surfaces induced by chemical mechanical polishing. Compared with conventional mechanical removal by alumina and silica, rare earth abrasives achieve selective material removal on surface via their special chemical activity, without introducing microscopic scratches and defects. Nevertheless, polishing performance of rare earth abrasives depends on series of factors, e.g. size of abrasive particles, microscale topological structure, configuration of chemical slurry, auxiliary energy fields etc. As a result, it is significant to conduct a comprehensive review to understand state-of-the-art polishing technologies. This review summarizes the effect of polishing slurries composed of different rare earth abrasives on polishing performance under different conditions. Additionally, various energy-assisted polishing strategies are discussed using diverse kinds of rare earth abrasives for distinct polishing forms. Finally, future directions of polishing on rare earth abrasives are addressed.

Aqueous hydrotropes: An efficient and reusable catalyst for the synthesis of 3-carboxy-coumarin motifs at room temperature

The coumarin moiety plays an important role in the large number of natural products possessing different kinds of biological diversity. Coumarin carboxylic acids show a wide range of biological activities in the pharmaceutical and agricultural fields. Knoevenagel condensation is one of the important reaction pathways for synthesizing coumarin derivatives, and many methodologies have been developed to synthesize this class of compounds. A more environmentally friendly method of synthesizing 3-carboxy coumarins has been successfully carried out using 50% aqueous NaPTS hydrotropes at room temperature, along with various substituted 2-hydroxy benzaldehydes and Meldrum’s acid. This process involves Knoevenagel condensation followed by intramolecular cyclization, providing better product yields (78-95%).

Rhetorical use of Sobolo (Hibiscus drink) as Yesu Mogya (Blood of Jesus) for Holistic Healing in Contemporary Ghanaian Christianity: A Critical Analysis from the Perspective of Biblical Theology and Christian Ethics

This article sought to survey the rhetorical use of Sobolo (hibiscus drink) as Yesu Mogya (the blood of Jesus) for holistic healing in contemporary Ghanaian Christianity. From the perspective of Biblical Theology and Christian Ethics, it argued that the phenomenon of using plant products and symbolic objects for miraculous healing is both explicitly and implicitly rooted in the Bible. Contrary to the dispensationalist perspective with its emphasis on the cessation of miraculous healing in some Western contexts and within scholarship, the continuous relevance of miraculous healing in Ghanaian Christianity is not much debated in the ecclesial context. It is, therefore, maintained that the use of symbols such as Sobolo for healing creates opportunities for the wholistic needs of the members of the church to be met. These needs are claimed to be fulfilled by spiritual means. From a Christian ethical perspective, this paper, however, cautions that sobolo as a miraculous drink in the Ghanaian Christian context should not be used as an exclusive means of physical well-being and development of society. It is further argued that the cyclical use of sobolo as a healing juice for all and diverse kinds of miraculous healings needs to be questioned in the light of biblical theology. Keywords: Wholistic Healing, Worldview, Biblical theology, Christian Ethics, Sobolo

Thermal response of TBC systems subjected to non-uniform thermal shocks and periodic thermal load: Effect of Biot number and interface imperfection

This study analytically examines the temperature variations within thermal barrier coating (TBC) systems under diverse kinds of thermal loadings, such as concentrated/distributed convective thermal shocks and oscillating thermal loads. In this study, the TBC system comprises ceramic top coat (TC) and NiCrAlY alloy bond coat (BC). The transient behavior of the TBC system facing various kinds of non-uniform convective thermal shocks is elaborated via the dual-phase-lag (DPL) heat conduction model. The effect of imperfect bonding of the TC/BC interface on transient responses of the regions in the neighborhood of the TC/BC interface is studied by considering impermeable, partially permeable and completely permeable heat flux flows. Laplace and Fourier integral transforms are employed to derive the exact solutions of time-dependent temperature fields governing equations. The prominent effects of sudden thermal impulse and steady alternating thermal loading on the variations of temperature within the TC, BC and substrate are inspected. The analysis reveals that the kind of thermal load, loading parameters, thermal properties and thickness of ceramic TC directly affect the transient/periodic temperature fields inside the TBC constituents. Meanwhile, the interface imperfection and the Biot number of convective thermal load play an impressive role in the severity of thermal response of the TBC constituents.

Dampak Kepribadian Narsistik terhadap quality of work life dalam Era Hybrid Working

Hybrid working is the work model chosen by many companies. In practice, changing your work style to a hybrid can affect the quality of work life. Quality of work life is an employee's perception which includes aspects of job and career satisfaction, general well-being, distance from homework, stress at work, control at work, working conditions. On the other hand, employee personality is a kind of diversity in the workplace. One of the personalities in the workplace is the personality of narcissism. Narcissism is part of the dark triad personality. Narcissism is demonstrated by behavior of self-admiration, domination, and superiority. The aim of this research is to explain the role of narcissistic personality in the quality of work life of employees who work in a hybrid manner. The participants were 217 hybrid working employees who filled out the Quality of work life and Short Dark Triad Personality scale instruments. The participants consisted of government agency employees, male and female, private employees, government agencies and start-ups, ranging in age from 20 to 55, with D3 to S3 educational backgrounds. Participants were selected using a purposive sampling method. The research results show that narcissistic personality plays a role in the quality of work life (b=0.055; p<0.001). Companies need to manage narcissistic traits through personnel management to improve the quality of work life in a hybrid work environment.

PREDICTIONS AND VERIFICATIONS OF UNIVERSAL COOPERATIVE RELAXATION AND DIFFUSION IN MATERIALS

ABSTRACT Since its inception in 1979, the coupling model has predictions on the dynamic properties of relaxation and diffusion that should be universal in materials with many-body interactions. The verifications of this bold prediction require studies of many different relaxation and diffusion processes in diverse kinds of material. These tasks, performed over the past four decades, have culminated in the overwhelming confirmation of the predictions as reported in my previous extensive review (Prog. Mater. Sci.139, 101130 [2023]). A large variety of relaxation and diffusion processes in widely different classes of materials are shown to have the predicted universal properties. In particular for polymers, the local segmental relaxation responsible for glass transition conforms to the universal properties. However, not known is whether diffusion of the entangled chains in high molecular weight polymers also follows the same properties. Published data of the diffusion of entangled polymer chains from experiments and simulations are reexamined and reevaluated to show indeed that they are in conformity with the universal properties. The same conclusion holds also for diffusion and rheology of entangled cyclic polymers. This paper is written as a tribute to C. Michael Roland for his scientific collaborations and camaraderie with me over many years.

Things to consider affecting secure, avoidant-fearful, and preoccupied attachment among mental health clients

Working alliance (WA) has been demonstrated to be a critical factor affecting treatment effectiveness. The relationship between patients' fundamental perceptions of attachment of WA and the efficacy of treatment as a result is becoming more widely acknowledged. To discover and examine the variables that affects the growth of solid attachment, avoidant-fearful attachment, and preoccupied attachment in psychologically ill patients. The research particularly seeks to investigate the many variables that influence these diverse kinds of attachments in people needing psychological treatment. The main healthcare psychologists enrolled 303 individuals who were scheduled for counseling. Self-report surveys on mental disorders, WA, and attachments were filled out by respondents. Participants who felt safer in their relationship with the psychotherapist displayed considerably higher WA. Increase in result was also connected with initial attachments to the psychotherapist in a subset of patients who finished treatment. According to the research, therapeutic connection is a significant WA prediction. According to the findings, connection to a psychotherapist might be more significant in regards to WA that previous attachments patterns.

Sexual diversity and streaming television: Toward a platform studies approach to analyzing LGBTQ+ TV

This essay argues for the utility of a platform-studies approach alongside textual analysis when studying the politics of sexual representation in contemporary television programming. Using a corpus of four LGBTQ+-themed programs that represent queer and trans sexualities and HIV/AIDS, the paper argues that funding mechanisms play a constitutive role in determining the kinds of sexual diversity that can circulate via streaming technologies. Comparing and contrasting content created for SVODs, BVODs, and video-sharing platforms, the essay considers the impact that the economic diversity of television’s multiplatform ecology has on the sexual diversity of content that circulates there. Purposefully combining an analysis of online TV with social media entertainment, the essay casts ‘streaming television’ as a wide, varied category whose relationship to questions of representational diversity is more complex than existing scholarship on these issues sometimes suggests. Situating its analysis in the literatures of platform studies, media industry studies, and television’s politics of LGBTQ + representation, the essay shifts the purview of ‘diversity’ away from representations of identity and toward diversities of funding mechanisms and diversities of sexual acts and practices. The essay argues for the necessity of textual analysis to properly articulate the relationship between platforms and the politics of sexual representation in the content that they circulate.

Enzymatic Dissociation of DNA-Histone Condensates in an Electrophoretic Setting: Modulating DNA Patterning and Hydrogel Viscoelasticity.

Development of an energy-driven self-assembly process is a matter of interest for understanding and mimicking diverse ranges of biological and environmental patterns in a synthetic system. In this article, first we demonstrate transient and temporally controlled self-assembly of a DNA-histone condensate where trypsin (already present in the system) hydrolyzes histone, resulting in disassembly. Upon performing this dynamic self-assembly process in a gel matrix under an electric field, we observe diverse kinds of DNA patterning across the gel matrix depending on the amount of trypsin, incubation time of the reaction mixture, and gel porosity. Notably, here, the micrometer-sized DNA-histone condensate does not move through the gel and only free DNA can pass; therefore, transport and accumulation of DNA at different zones depend on the release rate of DNA by trypsin. Furthermore, we show that the viscoelasticity of the native gel increases in the presence of DNA and a pattern over gel viscoelasticity at different zones can be achieved by tuning the amount of enzyme, i.e., the dissociation rate of the DNA-histone condensate. We believe enabling spatiotemporally controlled DNA patterning by applying an electric field will be potentially important in designing different kinds of spatiotemporally distinct dynamic materials.

Discovery of Cloud Applications from Logs

Continuous discovery and update of applications or their boundaries running in cloud environments in an automatic way is a highly required function of modern data center operation solutions. Prior attempts to address this problem within various products or projects were/are applying rule-driven approaches or machine learning techniques on specific types of data–network traffic as well as property/configuration data of infrastructure objects, which all have their drawbacks in effectively identifying roles of those resources. The current proposal (ADLog) leverages log data of sources, which contain incomparably richer contextual information, and demonstrates a reliable way of discriminating application objects. Specifically, using native constructs of VMware Aria Operations for Logs in terms of event types and their distributions, we group those entities, which then can be potentially enriched with indicative tags automatically and recommended for further management tasks and policies. Our methods differentiate not only diverse kinds of applications, but also their specific deployments, thus providing hierarchical representation of the applications in time and topology. For several applications under Aria Ops management in our experimental test bed, we discover those in terms of similarity behavior of their components with a high accuracy. The validation of the proposal paves the path for an AI-driven solution in cloud management scenarios.

African forex markets: Modeling their predictability and the asymmetric effects of oil and geopolitical risk

This study investigates the African forex (FX), geopolitical risk (GPR) and oil associations, resorting to the quantile-based causality, parametric quantile regression (QR), and non-parametric quantile-on-quantile regression (QQR) methodologies. We explore 16 major African currency markets. The sample contains daily data and spans from July 2000 through August 2023. Our results zoom on the differences in the FX-GPR-oil interactions at different market conditions of the dependent and independent variables, proxied for each case by 19 quantiles from 0.05 to 0.95. We find that the African FX returns are significantly asymmetrically predicted by both WTI oil and GPR. Our tail-based causality analysis uncovers the directional causal flow from GPR and Oil (WTI) to foreign exchange rates. We also report on salient asymmetries in the responsiveness of country-specific African FX returns to oil and geopolitics-driven shocks. In addition, the results of our QR analysis show a mix of positive and negative GPR and Oil effects, characterized by varying degrees of significance for different currencies. Our QQR analysis also reveals that GPR and WTI oil exert asymmetric effects on African FX returns. The returns of several African forex markets demonstrate negative relationships with GPR, especially at the lower tails of GPR and/or WTI oil, as usually the extreme-tailed conditions are driven by diverse kinds of crises, well covered by the analyzed dataset. Our outcomes cater relevant knowledge for scholars, FX investors, traders and regulatory bodies.

Inverse Adversarial Diversity Learning for Network Ensemble.

Network ensemble aims to obtain better results by aggregating the predictions of multiple weak networks, in which how to keep the diversity of different networks plays a critical role in the training process. Many existing approaches keep this kind of diversity either by simply using different network initializations or data partitions, which often requires repeated attempts to pursue a relatively high performance. In this article, we propose a novel inverse adversarial diversity learning (IADL) method to learn a simple yet effective ensemble regime, which can be easily implemented in the following two steps. First, we take each weak network as a generator and design a discriminator to judge the difference between the features extracted by different weak networks. Second, we present an inverse adversarial diversity constraint to push the discriminator to cheat generators that all the resulting features of the same image are too similar to distinguish each other. As a result, diverse features will be extracted by these weak networks through a min-max optimization. What is more, our method can be applied to a variety of tasks, such as image classification and image retrieval, by applying a multitask learning objective function to train all these weak networks in an end-to-end manner. We conduct extensive experiments on the CIFAR-10, CIFAR-100, CUB200-2011, and CARS196 datasets, in which the results show that our method significantly outperforms most of the state-of-the-art approaches.

Self‐care rhetoric and institutional culpability: Theorizing the academy and intellectual labor

AbstractSelf‐care, a ubiquitous concept commonly touted as the solution to an array of modern‐day problems, implies unapologetic selfishness aimed at preserving mental, emotional, and physical health. The overtly individualistic framing in its most common usage—the centering of oneself for the sake of oneself—obscures power relations and structural/institutional inequalities that create the need for self‐care. To deal with difficult work or family lives, taking up a hobby or some kind of diversion offers an escape that feels good; self‐care serves as a kind of coping mechanism, but not a solution to a social problem. It also lets society, or more specifically, managers and administrators in organizations, off the hook because it places the onus on individuals to deal with challenges on their own rather than situating them as social problems. We critique shortcomings in self‐care rhetoric employed by organizations—and specifically university administrators—to their members, by extending Hochschild's economy of gratitude framework.

Learning from diversity: Public reason and the benefits of pluralism

The New Diversity Theory (NDT) represents a novel approach to public reason liberalism, providing an alternative to the traditional, Rawlsian public reason paradigm. One of the NDT's distinctive features is its emphasis on the potential advantages of a diverse society, with a particularly strong focus on the epistemic benefits of diversity. In this paper, I call into question whether societal diversity has the epistemic benefits that New Diversity theorists claim. I highlight a number of pernicious epistemic phenomena that tend to arise in diverse contexts, ultimately arguing that the only feasible way around these epistemic pitfalls is through widespread convergence on certain intellectual virtues. If these virtues are indeed necessary, then the benefits highlighted by the NDT should only be expected in societies that reflect certain kinds of diversity. More precisely, only the kinds of diversity that can still persist despite homogenization along the lines of certain intellectual virtues are compatible with the NDT's claims. Building upon this insight, I then highlight features of the NDT that require further development in order for it to serve as a compelling alternative to its Rawlsian counterpart.

Going Local: An Agency-Based Approach to Collapse, Resistance, and Resilience in Hittite Anatolia

Abstract Crisis and collapse have long been prominent themes in Hittite studies (much more so than the related topics of resistance and resilience) and most of the extant body of scholarship on these themes have concentrated on the disintegration of the Hittite Empire around 1200 BCE. Though the events, conditions and processes that culminated in the disintegration of the Hittite Empire elude historical reconstruction, recent studies have unanimously rejected monocausal explanations of collapse in favor of the view that it was brought about by a combination of factors – internal, external, acute or chronic. In Hittite scholarship, the study of collapse and its aftermath have typically operated within a markedly state-centered and progressivist framework, focusing primarily on figuring out “what went wrong.” Meanwhile, especially in text-based studies, the agency and resilience of local, small(er)-scale, peripheral, and non-state individuals and communities, as well as their role in the construction, maintenance, and collapse of the Hittite empire, remain largely overlooked. The aim of the present paper is to shift the focus and scale of analysis away from the state, and to draw out from the textual record, the long-term agency, resistance, and resilience of local, small-scale, and often non-state individuals, communities, or socio-political institutions, which have typically been left out of text-based modern narratives. This paper will reassess the prominent view of the Hittite king (and state) as the absolute political, military, judicial, and religious authority, and argue that certain local and non-state communities and socio-political institutions exercised diverse kinds of agency, were remarkably resilient in the long term, and survived the final collapse of the Hittite state. In order to situate the inquiry in its broader scholarly and intellectual context, it will begin with an overview of where things stand in the study of the Hittite collapse. The next step will be to identify individual or collective local actors in the textual record. It will lastly focus on the interactions of diverse local agents with the Hittite state.
