Communication network security situation analysis based on time series data mining technology
Authors: Jiang Qingjian
Published: May 2024

Communication network security situation analysis prevents unauthorized users from accessing and stealing sensitive information. Network security analysis aims to monitor, discover, and eradicate security flaws by carefully examining the network’s architecture, data, and traffic to ensure safety. In time series data mining analysis by cyber terrorism, specialists must pay attention to cyber security, which involves identifying the elements contributing to long-term trends or systemic patterns via pattern-matching algorithms and other types of inferential processing on large datasets. The challenging characteristics of communication network security situation analysis are data loss, security breaches, hacking, and viruses. Hence, in this research, attention mechanism-based convolutional neural network-enabled practical byzantine fault tolerant (AMBCNN-PBFT) has been designed to improve communication network security situation analysis in time series data mining. AMBCNN-PBFT helps to increase communication network security usage and support the expansion during the evaluation system by optimizing the time series data mining. AMBCNN-PBFT effectively predicts the rise in the communication network, associated with faster times series benefits data mining approach. The study concludes that the AMBCNN-PBFT efficiently indicates and validates the communication network security in time series data mining during the evaluation system. The experimental analysis of AMBCNN-PBFT outperforms the data mining time series in terms of accuracy, efficiency, performance, and prediction.
Assessment of Reliability of Power Systems Under Adverse Weather Condition Using Markov System Dynamic Method
Authors: Eskandari-Kataki Fateme , Owlia Mohammad Saleh , Jafarian-Namin Samrad
Published: May 2024

We aim to extend the Markov System Dynamic method (MSD) to evaluate the reliability of repairable systems in two-state weather (2SW) models. Increasing the number of components in real practices has limited the use of the Markov method, because of increasing the number of equations and the complexity of the problem. There is no such restriction in the MSD method. Thus, it can be applied to complex systems. Theoretically, we indicate that the 2SW model is a type of linear dynamical system. Therefore, we can use MSD to solve it. Through an example, the validity of the proposed method is confirmed in comparison to the Markov method for the 2SW model. Since the MSD method does not use equations, it can be a preferred alternative for calculating the reliability of 2SW models. Accordingly, we apply the MSD method for assessing the reliability of a four-component system.

Published: May 2024

The aim of the study is to investigate foreign language teachers’ perspective on teaching older adults in the context of (glotto-)stereotypes about Polish third-agers. Thirty-seven lecturers, divided into two groups: one with and one without experience in teaching a foreign language to seniors, were examined. The survey study consisted of two stages based on 2 different research tools: online surveys and group interviews. Both individual responses from surveys and opinions expressed during group interviews were analyzed qualitatively with the use of a reflexive thematic analysis (TA) approach. The teachers responded to the questions regarding the following aspects: 1) seniors’ experiences in learning foreign languages; 2) older adults’ motivation, needs and expectations; 3) the role of the teacher; 4) didactic strategies. It turned out that the responses from the two groups did not differ a lot and in general the lecturers declared their willingness to work with late L2 learners. The influence of stereotypical thinking about seniors (based on the opinions of young Poles cited in the literature) on teachers who did not have experience working with this age group, was not as strong as presumed. None of the research groups’ members had had any formal education or training in teaching late L2 learners and, noteworthy, the attitudes and abilities of both teacher groups appeared to differ from the stereotypically held beliefs of Polish seniors. The comments from experienced teachers revealed their deeper awareness of seniors’ psychological needs, such as supporting them or giving positive feedback.

Atopic dermatitis is acknowledged as a vital inflammatory disorder associated with the integumentary system of the body and is characterized by the formation of thick reddish-grey scars and erythema formation on skin, prevalent amidst the populace. Numerous synthetic drugs are available for treatment like antihistamines, immunosuppressants, glucocorticoids etc., but contrarily, essential oil therapy is exclusively lime lighted to favour the purpose. The utilization of available engineered drugs, possess the marked adverse effects owing to prolonged duration of therapy and therefore, essential oils are explored well and proved to exhibit the anti-eczematic, anti-inflammatory and antipruritic properties. Ethereal distillates own the assorted and selective therapeutic properties attributable to presence of bioactive compounds liable to treat this torturous and integumentary disorder, likely lavender oil, patchouli oil, frankincense oil etc., have been found to exert their pharmacological actions by impeding the liberation and action of inflammatory mediators and immunological hyperactivities that are engaged in exacerbating this idiopathic illness. The current attempt provided the update with the aim to bring forth the naturally originated treatment that is pertinent to provide the invulnerable therapy by circumventing the noxious symptoms i.e. erythema formation and inflamed lesions.

Authors: Das Debaditya , Banerjee Mainak , Kar Anish , Bhattacharyya Rana , Chowdhury Subhankar , Mukhopadhyay Satinath
Published: May 2024

Objectives

Primary hyperparathyroidism (PHPT) in paediatric and adolescent age group presents with some unique challenges for clinicians. While the disease in the adult counterparts presents with symptoms which are described quite extensively in literature, children/adolescents have manifestations which are quite different and severe compared to the former. The present case series aimed to highlight the peculiarities of presentation of PHPT in children and adolescents.

Case presentation

In this case series, we present experience of 5 cases of PHPT in children and adolescents from our centre. We compared our data with the data already available in literature. We have also described salient presenting features of PHPT in individuals less than 19 years old previously reported in literature and pointed out the specificities of this disease at this age group.

Conclusions

PHPT in children and adolescents should be considered as a separate entity compared to that in adults, given its unique features, such as rachitic features, and severity of different presenting phenotypes. Persistence of rachitic features despite vitamin D correction, pancreatitis, bilateral nephrolithiasis and otherwise unexplained psychiatric abnormalities of insidious onset require greater clinical vigilance and serum/urine calcium testing to rule out this uncommon yet possible entity.
Exploring the clinical utility of exome sequencing/Mono, Duo, Trio in prenatal testing: a retrospective study in a tertiary care centre in South India

Published: May 2024

Objectives

With the availability of Next Generation Sequencing (NGS) diagnosis of genetic disorders has improved significantly. Its use is also applicable to ascertain diagnosis and management in a perinatal setting. The study aims to detect the genetic aetiology of various congenital structural and functional defects using NGS technology in the reproductive cohort at a tertiary centre. The secondary objective is to address challenges in the interpretation of variants.

Methods

This was a retrospective study of couples who underwent exome sequencing (Mono-testing proband only or Duo-testing parents only or Trio-testing proband and parents) for suspected single gene disorders between years 2020–2022 at a tertiary care perinatal center in the South India. American College of Medical Genetics (ACMG) guidelines were followed to classify the pathogenicity of the variants identified by exome sequencing.

Results

The overall diagnostic yield as defined by pathogenic/likely pathogenic variants obtained was (23/43) 53.4 %. The individual subsets have the following diagnostic yield viz., Mono 5/6 (83 %); Carrier 16/32 (50 %); Trio 2/5 (40 %). Diagnostic yield was significantly higher in consanguineous couples. However, miscarriage history, and organ system involvement did not have a significant effect on the diagnostic yield. Prenatal diagnosis was offered for seven patients based on the exome result. One fetus was confirmed with a compound heterozygous pathogenic variant.

Conclusions

Diagnostic yield of exome sequencing in our cohort was 53 %. The detection of pathogenic variants was maximum in those cases undergoing Mono exome sequencing. In places where there is a high prevalence of consanguinity and endogamy, NGS may be offered as first line test in the context of prenatal diagnosis.
Introducing Bed Word: a new automated speech recognition tool for sociolinguistic interview transcription
Authors: Ma Marcus , Glass Lelia , Stanford James
Published: May 2024

We present Bed Word, a tool leveraging industrial automatic speech recognition (ASR) to transcribe sociophonetic data. While we find lower accuracy for minoritized English varieties, the resulting vowel measurements are overall very close to those derived from human-corrected gold data, so fully automated transcription may be suitable for some research purposes. For purposes requiring greater accuracy, we present a pipeline for human post-editing of automatically generated drafts, which we show is far faster than transcribing from scratch. Thus, we offer two ways to leverage ASR in sociolinguistic research: full automation and human post-editing. Augmenting the DARLA tool developed by Reddy and Stanford (2015b. Toward completely automated vowel extraction: Introducing DARLA. Linguistics Vanguard 1(1). 15–28), we hope that this resource can help speed up transcription for sociophonetic research.
Why Would a Monarchist Vilify the Rich? Marx and Engels on Balzac
Authors: Giladi Tal Meir
Published: May 2024

Engels explained his admiration for Balzac by pointing to an apparent discrepancy between Balzac’s literature and his politics. Despite his sympathies for the French nobility, Balzac’s realism “compelled” him to portray this class in unflattering terms. In this article, I challenge Engels’s reading, arguing that Marx’s scattered remarks on Balzac take us in a different direction. Specifically, I argue that in his remark on Balzac’s The Peasants Marx pinpointed the author’s preoccupation with the spread of bourgeois ideology into the nobility. Building on this remark, I analyze several of Balzac’s works showing that insofar as Balzac lambasted the nobles, his critique was primarily directed towards nobles who had adopted bourgeois ways. In this light, and against Engels’s observation, Balzac’s critique of the nobles appears to stem from his sympathy to aristocratic values rather than conflicting with them. In showing that affinities between Balzac, Marx and Engels did not depend on Balzac expressing anti-noble sentiment, I argue that the admiration the fathers of communism had for the monarchist’s prose exemplifies a partial, yet typical convergence between socialists and conservatives in their critique of modern bourgeois society.
Power in Närke. Elite settlement and animal art AD 150–1125 in a Swedish province
Authors: Rundkvist Martin
Published: May 2024

This survey of archaeological and onomastic evidence, prominently including Style I–III animal art, aims at identifying the most promising locations where elite manorial settlements of the period AD 375–1125 can be expected in the Medieval Swedish province of Närke. One such site of c. AD 600–800 has been partly excavated at Husby in Glanshammar. This parish is one of six that stand out by their unusually rich, numerous and sustained elite indications. A recent campaign of large intensive metal detector investigations has proven both a boon and a bias in terms of new evidence. None of the six most promising parishes would however fall off the elite map even without the new metal detector finds. Of the place names, Tuna appears to be irrelevant to Närke’s elite, while two out of three Husby names correlate with Viking Period elite indicators.

We build the time-varying parameter feature into the (Sims, E., J. C. Wu, and J. Zhang. 2023. “The Four-Equation New Keynesian Model.” The Review of Economics and Statistics 105 (4): 931–47) four-equation Dynamic Stochastic General Equilibrium (DSGE) model in this paper. We find that both parameters and impulse responses of the variables in the four-equation DSGE model exhibit significant variation over time. Allowing model parameters to vary over time also improves the model’s forecasting performance.
Asymmetric Activation of ON and OFF Pathways in the Degenerated Retina
Authors: Carleton Maya , Oesch Nicholas W.
Published: May 2024

Retinal prosthetics are one of the leading therapeutic strategies to restore lost vision in patients with retinitis pigmentosa and age-related macular degeneration. Much work has described patterns of spiking in retinal ganglion cells (RGCs) in response to electrical stimulation, but less work has examined the underlying retinal circuitry that is activated by electrical stimulation to drive these responses. Surprisingly, little is known about the role of inhibition in generating electrical responses or how inhibition might be altered during degeneration. Using whole-cell voltage–clamp recordings during subretinal electrical stimulation in therd10and wild-type (wt) retina, we found electrically evoked synaptic inputs differed between ON and OFF RGC populations, with ON cells receiving mostly excitation and OFF cells receiving mostly inhibition and very little excitation. We found that the inhibition of OFF bipolar cells limits excitation in OFF RGCs, and a majority of both pre- and postsynaptic inhibition in the OFF pathway arises from glycinergic amacrine cells, and the stimulation of the ON pathway contributes to inhibitory inputs to the RGC. We also show that this presynaptic inhibition in the OFF pathway is greater in therd10retina, compared with that in thewtretina.

Published: May 2024

In this study, extraction conditions of proteins from Sargassum vulgare were optimized. The Box-Behnken design (BBD)-based Response Surface Methodology (RSM) was used to investigate and optimize the protein content (PC), total phenolic content (TPC), and antioxidant activity (AOA), which were affected by extraction parameters (ultrasonic probe time: 0.09-2.91 min and enzyme/substrate ratio (E/S): 0.18-1.02). The optimal extraction was achieved while applying an ultrasonic probe for 2.5 min and using an E/S of 0.90. Under this optimum conditions PC and TPC were found to be as 248.30 mg protein/g dry weight (dw) and 38.03 mg gallic acid equiavalent (GAE)/g dw, respectively. Moreover, AOA was determined to be 53.77 mg Trolox equivalent (TE)/g dw by CUPRAC and 19.88 mg TE/g dw by ABTS methods. These findings provide a good basis for future research into the potential of macroalgae protein extracts, which have a high protein content and antioxidant potential for food industry.

Published: May 2024

Producing sustainable concrete and mortar is the idea that have been investigated by many researchers in the world through using waste materials in the mortar or concrete compositions to reduce the thread on the environment. In order to predict the compressive strength of mortar, this article proposes statistical models utilising linear regression (LR), nonlinear regression (NLR), and artificial neural network (ANN) based on experimental data collected from prior research in the field. The pozzolanic material used in mortar is agricultural waste, specifically Palm Oil Fuel Ash (POFA). In order to choose the most efficient model, the proposed models were evaluated using several statistical parameters. When compared to alternative models (Linear regression, nonlinear regression, and ANN), the one developed using ANN proved to be the most efficient in terms of approach, giving lower values for root mean square error (RMSE) and mean absolute error (MAE) which were 5.11, and 4.175 respectively. The suggested ANN model performed well according to the scatter index (SI), and the coefficient of determination value (R2) value was 34% more than the R2 in the LR model and 23% greater in the NLR model.
Shear Strength of Soft Soil Reinforced with Singular Bottom Ash Column
Authors: Zaini Muhammad Syamsul Imran , Hasan Muzamir
Published: May 2024

Structures construct on soft clays are often affected by stability and settlement problems due to high compressibility, low shear strength and low permeability of soft clay which will lead to bearing capacity failure and excessive settlement. The soft clay samples had the dimensions of 50 mm diameter and 100 mm in height. The bottom ash column had two (2) different area replacement ratios which were 4% and 9% (10 mm and 15 mm diameters respectively) with the bottom ash column penetration ratio of 0.3, 0.7 and 1.0. The results of the unconfined compression test show that there is an improvement in shear strength of soft kaolin clay when reinforced with bottom ash column. For samples with area replacement ratio 4%, the results show the increment of 25%, 37.5% and 50% at height penetrating ratio of 0.3, 0.7 and 1.0, respectively in shear strength. Meanwhile, for samples of 9% area replacement ratio, the shear strength of the soft kaolin clay increased about 14.29, 28.57 and 57.14%, respectively. It can be concluded that by reinforcing the soft clay using singular bottom ash column, the shear strength of the soils increases and become more significant as the area replacement ratios and the column penetration ratios increase.

Authors: Apriani Dyah Wahyu , Qusairy Muhammad Ichsan
Published: May 2024

A site study is conducted to comprehend the stratigraphy, soil type, water depth, and soil deformation qualities. Using this data, cost-effective substructure designs, supporting structure research, alternative development plans, and the site's safety are all possible. Site investigations must be planned to obtain maximum information, represent field soil conditions, and be relevant to development. Excessive investigations waste money and time, while insufficient investigations raise the risk of failure of the constructed structures and cause the data not to reflect the area's conditions accurately. Planners can determine where a site investigation should be conducted in each area by mapping possible investigation locations. The Standard Penetration Test and Cone Penetration Test site investigation location data are used in this study to map possible site investigation locations using spatial analysis in GIS, yielding recommended investigation locations. Elevation, slope, and prior site studies are the three parameters combined to create the weighting method, fuzzy overlay gamma, and per-cell statistical maximum employed in the spatial analysis. The inference matrix is used to validate the accuracy of the spatial analysis results. The inference matrix validation results indicate that the weighting approach has a higher accuracy rate of 63,55%. The findings indicated that the southeast, northeast, and west of the research site had significant potential for site studies in limited regions

Abstract.This research paper is to study the decreasing strength of a 22,1 meter long span Prestressed Concrete U Girder due to two strands in a tendon out of six tendon are not being able to be stressed. This matter is a cause of an error in the implementation of the PC-U girder manufacturing resulted in a reduction in the area of the tendon sleeve (duct), two out of seven pieces of the strand cannot be inserted completely. PC-U girder performance will suffer a strength decrease, it needs to be checked and handled.  This paper is an actual project condition and researched to verify how much strength reduction due to such a case.  Analysis is performed to measure and compare the moment capacity of a cross-sectional conditions in accordance with the results of the designed section. Moment capacity analysis is carried out to determine the ability of the cross section to support the working load with a bonded tendon. Research methodology involves calculation of moment capacity Mu using trial and error processes of calculating the depth of neutral axis c using Equilibrium Equation so that with a trial c value, ultimate prestressed strain value εpu and ultimate prestresses stress value σpu are coincided in the Moment-Curvature curve line. Using the overlapped c value, Moment capacity of the girder with full strand can be calculated. A similar procedure is performed with reduced strand number. The difference between the two are the reducing prestressed concrete strength. Evaluating both analyses, it is found that a decrease in the moment capacity of the cross section as much as 530,93 kNm to the designed moment capacity of 18.108,06 kNm or approximately 2,93% of its original designed strength.

Humble AI for 22nd century medicine
Authors: G Brown David , W Samuelson Frank
Published: May 2024

Artificial intelligence (AI) is playing an increasingly important role in medicine. We examine the current trends in the evolution of this role and attempt to understand how it may develop over the next two hundred years, as the very nature of human existence may be altered. We are concerned with weaknesses in the AI development and deployment processes, in particular with lapses in the use of AI evaluation methodology and in the tendency of both humans and AI systems to accept unquestioningly the conclusions reached by such systems. We posit the need for a “humble” AI aware of its own limitations and of the limitations of its ambit. Without serious attention to these aspects of AI, it may come to represent an existential threat to our species. We reference examples from popular culture to illustrate these concerns.

Amorphous alumina coatings, intended as hydrogen barriers, were successfully deposited on Fe-8 wt% Cr substrates by plasma ion-assisted deposition technique. The amorphous structure of the coatings was confirmed by transmission electron microscopy and X-ray diffraction. The interfacial and mechanical properties of the coating-substrate system were evaluated using an in-house custom-designed backside electrochemical hydrogen charging method. In this approach, the substrate side faces the electrolyte (hydrogen entry side) and the mechanical behavior was tested on the coating side (hydrogen exit side). A Kelvin-probe-based measurement was performed to determine the hydrogen diffusivity in these amorphous alumina coatings at room temperature using a similar backside charging approach. Chemical and microstructural characterizations, in combination with scratch and hardness testing, show that interfacial hydrogen accumulation is strongly responsible for drastic changes in the scratch morphology of the coating and its adhesion to the substrate. Scratch testing promises to be a quick and easy technique to fingerprint changes at the coating/substrate interface upon hydrogen exposure.

The object of this study is a clustering algorithm using various technologies.
This paper compares clustering algorithms that are more commonly used to analyze urban road network trajectories, the growth curve model, with the elbow method and the x-means algorithm. Experiments were conducted with various volumes of big data to determine calculation time, accuracy, and ways to increase calculation time. These results can be used to manage traffic jams in congested areas and city streets. Considering the widespread use of clustering algorithms for solving various problems, this study proposes to introduce GCM, SPGK methods for monitoring and analyzing the state of congestion on city roads. The work was carried out in the following steps: research and selection of methods based on efficiency and time, implementation of parallel computing technologies to improve computation speed, demonstration of the selected method based on collected data from a real city with visualization of the results. The growth curve model algorithm has been proven to be almost 5 times more effective than the elbow method and the x-means algorithm. The time allocated for data processing has been calculated. An increase in the volume of processed data showed an almost stable execution time t = 3 s for the GCM algorithm for data with a volume of up to almost 2,000 units. The effectiveness of SPGK-means was shown for different values of the number of points. Models of the Chengdu transport network obtained using a clustering algorithm with maximum grid density of neighborhoods are presented. There are some deviations between the grid and the road network due to the large grid size. This error is explained by an error of up to one between the points and the real grid.
The results obtained clearly show how optimization of congested roads can be influenced. They provide information to obtain data on available routes, which allows you to analyze the road network individually and as a whole
Development of RAMDOE: a new method for rapidly ranking alternatives with supplementary options and considering changes in criteria values
Authors: Trung Do Duc , Dua Tran Van
Published: May 2024

This paper delves into the development and validation of the RAMDOE method, a pioneering approach in multi-criteria decision making (MCDM) that seamlessly integrates the root assessment method (RAM) and design of experiments (DOE) techniques, addressing the inflexibility of traditional MCDM methods in accommodating adjustments in criteria ranges and the addition of new alternatives without necessitating a complete overhaul of the decision framework. Through empirical analysis, the study demonstrates the RAMDOE method's remarkable efficacy in precisely ranking alternatives, as illustrated through a practical case study focused on the selection of a supplier from a pool of seven candidates. One of the most notable aspects of the RAMDOE method lies in its capacity to formulate a regression equation that accurately captures the intricate relationship between alternative scores and criteria values, enabling decision-makers to seamlessly integrate new alternatives into the decision-making process without the cumbersome task of recalibration, thereby distinguishing it from conventional MCDM techniques such as TOPSIS (technique for order of preference by similarity to ideal solution), COPRAS (complex proportional assessment), MOORA (multiobjective optimization on the basis of ratio analysis), EDAS (evaluation based on distance from average solution) and CODAS (combinative distance-based assessment). The practical implications of these findings are profound, offering decision-makers across various domains a more efficient and adaptable framework to navigate complex decision scenarios. Particularly in contexts like supplier selection, where criteria ranges may vary significantly, the RAMDOE method provides decision-makers with a robust toolset to make informed decisions, presenting a promising avenue for addressing the dynamic nature of decision-making environments and enhancing the overall robustness and flexibility of MCDM processes in real-world applications
Reducing the volume of computations when building analogs of neural networks for the first stage of an ensemble classifier with stacking
Authors: Galchonkov Oleg , Baranov Oleksii , Chervonenko Petr , Babilunga Oksana
Published: May 2024

The object of research in this work is ensemble classifiers with stacking, intended for the classification of objects in images with the presence of small sets of labeled data for training. To improve the quality of classification at the first stage of such a classifier, it is necessary to place more primary classifiers that differ in heterogeneous structured processing. However, the number of known neural networks with appropriate characteristics is limited. One approach to solving this problem is to build analogs of known neural networks that make classification errors on other images compared to the base network. The disadvantage of the known methods for constructing such analogs is the need to perform additional floating-point operations. The current paper proposes and investigates a new method to form analogs through random cyclic shifts of rows or columns of input images. This has made it possible to completely eliminate additional floating-point operations. The effectiveness of using this method is explained by the structured processing of input images in basic neural networks. The use of analogs obtained by the proposed method does not impose additional restrictions in practice. This is because the heterogeneity of structured processing in basic neural networks is a typical requirement for them in an ensemble classifier with stacking.
The simulation for the CIFAR-10 data set demonstrated that the proposed technique for constructing analogs allows for a comparative quality of classification by the ensemble classifier. Using MLP-Mixer analogs provided an improvement of 4.6 %, and CCT analogs – 5.9 %

The object of this study is the process of distribution of damaged weapons and military equipment of various types among specialized repair and restoration units.
The problem being solved is the lack of adaptability of the existing scientific and methodical apparatus to the expedient distribution of damaged weapons and military equipment of various types among specialized repair and restoration units.
An algorithm for the expedient distribution of damaged weapons and military equipment among specialized repair and restoration units is proposed, which is based on the method of non-linear programming (the method of two functions). The essence of the developed algorithm is to take into account the non-linearity of objective functions of both the consumer and the resource.
A feature of the developed algorithm of expedient distribution is taking into account the heterogeneity of both damaged weapons and military equipment, as well as the specificity of repair and restoration units.
The scope of practical application of the proposed algorithm is management processes in military hostilities during combat operations.
The procedure for appointing specialized repair and restoration units for the restoration of damaged weapons and military equipment has been improved.
The peculiarity of the proposed procedure is that it is based on the distribution of damaged weapons and military equipment not only on the basis of the capacity of certain repair and restoration units but also taking into account their compliance. The specified procedure makes it possible to select those repair and restoration units that could allow for an increase in the level of restoration of damaged weapons and military equipment by 20 %.
The scope of practical application of the improved procedure is the management processes of the technical support system of troops when planning measures to restore damaged weapons and military equipment
