Authors:   “Transilvania” University of Brașov, Romania, ISPĂȘOIU Adrian , MILOSAN Ioan ,   “Transilvania” University of Brașov, Romania
Published: November 2023

In many industrial activities carried out by workers, some parts of the human body or even the body as a whole are overused to a degree that can affect the health of the workers. Established ergonomic risk assessment methods include QEC and RULA, and these methods aim to assess the risk factors that may cause workers to develop WMSDs. The purpose of this study is to evaluate the ergonomic risks related to workers' bodily postures when they work on conveyor belts. By using the QRC and RULA methods comparatively, it is possible to see which of the two tools are more suitable for evaluation in this type of activity and which of the two methods offers a more accurate diagnosis. The ERGOWORK version 2.7B software application was used for data entry and processing, which implements both methods. Based on the results obtained, conclusions and recommendations were drawn regarding the workers' workstations, and these can be materialized in the redesign of the work equipment and/or the replacement of the worker, in the execution of certain operations, by automatic machines.

A note on vertex irregular total labeling of trees
Authors: Susanto Faisal , Simanjuntak Rinovia , Baskoro Edy Tri
Published: November 2023

The total vertex irregularity strength of a graph G=(V,E) is the minimum integer k so that there is a mapping from V ∪ E to the set {1,2,...,k} so that the vertex-weights (i.e., the sum of labels of a vertex together with the edges incident to it) are all distinct. In this note, we present a new sufficient condition for a tree to have total vertex irregularity strength ⌈(n1+1)/2⌉, where n1 is the number of vertices of degree one in the tree.

Published: November 2023

Let G and H be two given graphs. The notation F→(G,H) means that any red-blue coloring on the edges of F will create either a red subgraph G or a blue subgraph H in F. A graph F is a Ramsey (G,H)-minimal graph if F satisfies two conditions: (1) F→(G,H), and (2) (F−e) ⇸ (G,H) for every e ∈ E(F). Denote ℜ(G,H) as the set of all (G,H)-minimal graphs. In this paper we prove that a tree T is not in ℜ(mK2,bPn) if it has a diameter of at least n(b+m−1)−1 for m,n,b≥2, furthermore we show that (b+m−1)Pn ∈ ℜ(mK2,bPn) for every m,n,b≥2. We also prove that for n≥3, a cycle on k vertices is in ℜ(mK2,bPn) if and only if k ∈ [n(b+m−2)+1, n(b+m−1)−1].

Authors: Afifah Khairunnisa N. , Sugeng Kiki A.
Published: November 2023

A rainbow geodesic is a shortest path between two vertices where all edges are colored differently. An edge coloring in which any pair of vertices with distance up to d, where d is a positive integer that can be connected by a rainbow geodesic is called d-local strong rainbow coloring. The d-local strong rainbow connection number, denoted by lsrcd(G), is the least number of colors used in d-local strong rainbow coloring. Suppose that G and H are graphs of order m and n, respectively. The corona product of G and H, G ⊙ H, is defined as a graph obtained by taking a copy of G and m copies of H, then connecting every vertex in the i-th copy of H to the i-th vertex of G. In this paper, we will determine the lsrcd(Cm ⊙ Cn) for d=2 and d=3.

Published: November 2023

Natural compounds with indolizine scaffolds have demonstrated numerous biological activities and have found use in medical research laboratories. Thys, the unique indolizine scaffold became an important system for the development of new drug candidates in medicinal chemistry. [1,2] Several indolizines with excellent anticancer activity and tubulin polymerization inhibitory potency have been reported recently, and our group contributed also to the field. [1,3] The goal of this study was the design, synthesis and anticancer evaluation of several new derivatives with symmetrical or unsymmetrical substituted 7,7’-(ethene-1,2-diyl)bisindolizine structure, and several new 6-, 7- or 8-substituted indolizine derivatives. Mono and bisindolizines were synthesized in good yields via [3+2] dipolar cycloaddition of the in situ generated ylides, from corresponding N-pyridinium salts to ethyl propiolate. Part of the new derivatives were tested for their anticancer activity by screening against NCI’s 60 human tumour cell lines panel and the results are presented herein. In vitro experiments regarding tubulin interaction were performed for the active compounds.

Authors: Danova Natalia Y.
Published: November 2023

Importance. The problems of youth antisocial behavior pedagogical prevention in the educational environment are described. Development issue actualization of a comprehensive, harmonious personality designed to resist destructive ideology is worked out. One of the important issues is the formation of the “right” social environment for young people. The purpose of the process is to bring up an educated individual with a positive civic position who is ready to become an active participant in society.
Research Methods. The methodological basis of the research is philosophical-anthropological, axiological and personality-oriented approaches that determine the spiritual and moral education’s concept’s content guidelines. Within the framework of these approaches, scientific literature theoretical analysis, synthesis and generalization methods, as well as students’ personalized observation are used.
Results and Discussion. The role of socio-pedagogical activity in antisocial behavior prevention context in the youth environment is substantiated. The characteristic of “social criteria” in determining the children and adolescents’ behavior is given. Antisocial behavior demonstration forms in the youth environment are clarified.
Conclusion. The issue actualization shows the need to create a more advanced model of social and educational work on the antisocial behavior prevention among young people. Prevention should begin from early childhood. True upbringing, a positive parents’ example, caring for the child’s material and emotional satisfaction are the key to successful prevention of antisocial behavior. Not only educational institutions, but also federal and regional authorities should direct their efforts to achieve success in antisocial behavior prevention.
On the issue of circular migrations in the city of Kizlyar in the socio-economic policy context of the Russian Empire on cordon sections of the Caucasian Cordon Line Left Wing in the first half of the 19th century
Authors: Gazieva Abidat A.
Published: November 2023

Importance. A number of issues of circular and pendulum migrations in the city of Kizlyar during the Caucasian War as a part of the multi-vector Caucasian policy are developed.
Materials and Methods. The theoretical basis of the research is the concept of frontier, which allows considering the fortresses along the Caucasian Line as zones of economic communication. The system approach allowed considering a set of strategies for the development of fortress towns along the Caucasian Cordon Line as components of Caucasian policy, based on various methods of policy implementation and having feedback.
Results and Discussion. The socio-economic policy of the local administration is analyzed in the context of the Caucasian policy in general and the Caucasian War in particular. The economic frontier contributed to the influx of a large number of highlanders-itinerant-workers, which necessitated the regulation of migration processes and the formation of a trustee body over the highlanders. The development of capitalist relations, which were conditioned by the rapid pace of market development and, as a consequence, the increase in demand for the production sector, required an increase in the number of able-bodied population.
Conclusion. Despite the limited competence, the trustee over the highlanders fulfilled the function of involving the highlanders in the socio-economic space of the empire, as well as taking into account the migration processes in the city, prevented the actions of non-peaceful highlanders, aimed at ruining the city and undermining the economic activity of Kizlyar as a key link in the provision supply of fortifications in the Eastern Caucasus, internal trade of the gavernorates of the empire, as well as prevented the sale of strategically important in the conditions of war goods to the mountains.
Temperature dependence of dielectric nonlinearity of BaTiO3 ceramics
Authors: Fujii Ichiro , Trolier-McKinstry Susan
Published: November 2023

In many commercially utilized ferroelectric materials, the motion of domain walls is an important contributor to the functional dielectric and piezoelectric responses. This paper compares the temperature dependence of domain wall motion for BaTiO3 ceramics with different grain sizes, point defect concentrations, and formulations. The grain boundaries act as significant pinning points for domain wall motion such that fine-grained materials show smaller extrinsic contributions to the properties below the Curie temperature and lower residual ferroelectric contributions immediately above the Curie temperature. Oxygen vacancy point defects make a modest change in the extrinsic contributions of undoped BaTiO3 ceramics. In formulated BaTiO3, extrinsic contributions to the dielectric response were suppressed over a wide temperature range. It is believed this is due to a combination of reduced grain size, the existence of a core-shell microstructure, and a reduction in domain wall continuity over the grain boundaries.
Superhero Media as a Potential Context for Investigating Children’s Understanding of Morally Relevant Events
Authors: Martin Justin
Published: November 2023

Currently, superhero films are one of the more popular film genres, and the genre does not appear to be slowing down anytime soon. In addition, the lives and exploits of superheroes are told through other forms of media such as animated films and television series targeted towards children. However, these narratives are also violent. If older children (i.e., approximately 7–11) engage with superhero media, then it is important to understand the ways they attempt to make sense of this genre. To this end, the essay examines how superhero media may serve as a potential context for older children’s understanding of morally relevant events. This potential—based on three broad areas of scholarship on children’s capacities for understanding others and their morally relevant acts—is explored along two dimensions. The first is through common narrative features of the genre, and the second is through research implications. It is suggested that a research program utilizing the genre’s narrative features as a part of a methodology to investigate older children’s understanding of morally relevant acts affords unique opportunities to build upon existing scholarship on the relationship between media content and children’s moral understanding.

Published: November 2023

The ammonites in spherical carbonate concretions often preserve their original three-dimensional (3-D) shell shapes and detailed fragile structures. However, the formation process of spherical ammonite concretions is not fully understood. Herein, the ammonite concretions identified in the Cretaceous (Campanian) Osoushinai Formation, Yezo Group, Japan, are examined to understand their formation process during soft-tissue decomposition after burial in marine sediments. In the Osoushinai Formation, almost all observed ammonites in concretions preserve their 3-D form without phragmocone deformation. The calcite filling in the remaining body chamber of ammonites (BC1) shows that shells were buried with soft tissues. These occurrences, negative δ13C values, and the near-zero δ18O values of BC1 as well as the concretions indicate that both BC1 and concretions rapidly formed from dissolved inorganic carbon derived from organic matter, including the soft tissue of dead organisms, in the shallow part of the sediments. The increasing Fe concentration in BC1 shows that BC1 formed in the iron-reduction (FeR) zone, where organic matter was decomposed owing to the activity of iron-reducing microorganisms. The similarity of the elemental and isotopic compositions of BC1 and concretions show that they concurrently formed in the FeR zone. In the Osoushinai Formation, an abundant influx of Fe(III) and intense bioturbation during the deposition of the formation promoted organic decomposition in the FeR zone, causing rapid formation of BC1 and concretions. Such rapidly formed calcite fillings and concretions protected fossils from deformation and dissolution during diagenesis to preserve their 3-D form. Overall, the findings of this study provide new insight into the relation between sedimentary environments and the fossil preservation process via rapid concretion formation.
Study of creep and creep crack growth fatigue of aging ASTM A297 / A297M-19 HP steel modified with niobium

Published: November 2023

The HP steel has been commonly used in structural components that work at high temperatures, up to approximately 1150 ºC, with 927 °C being a typical working temperature. In this work, the mechanical properties of ASTM A297 / A297M-19 HP steel modified with niobium were characterized at as-cast microstructural conditions and after aging at 927 ºC for 1000 hours through mechanical tests of hardness, tensile, creep, fatigue, and metallographic analyzes. It was observed that the heat treatment of aging with the time of 1000 hours at 927 ºC provided the precipitation of secondary carbides (Cr23C6) in the austenitic matrix of the alloy and the presence of G-phase. Thus, the heat treatment of aging caused intense precipitation in the interdendritic space, where the chromium carbides coalesced and became coarser. The hardness results showed an increase of hardness by approximately 17% in the aged. In the tensile tests, it was observed that the aging increased the value of the mechanical resistance parameters and decreased the total elongation to approximately 48% when compared to the values obtained in the as-cast condition. The results of the Charpy impact tests on specimens with V-notches, performed at a temperature of 25 ºC, presented values lower than the values obtained at a temperature of 927 ºC in all conditions tested. In the creep tests, for the as-cast material, small variations of the Norton Diagram's stress exponent (n) were observed in the temperature range of 871 to 1066 ºC. It was noted that at the highest temperature of 1093 ºC, the stress exponent showed a sharp decrease due to the transition into dislocation-climb controlled mechanism zone. The fatigue crack propagation tests showed that the crack propagation rate da/dN, for each condition of the material, is higher at 927 ºC than at 25 ºC since the material presented better ductility at high temperatures. In creep crack growth tests, it was observed that the lower initial stress intensity factor (Ki) applied provided a decrease in the crack growth rate in the second stage when compared to the higher Ki value. The experimental results raised in the development of this work provided values of the parameters of monotonic mechanical strengths, nucleation, and crack propagation by fatigue and creep, which are of fundamental importance for the characterization, from the perspective of time-dependent fracture mechanics, the ability of the ASTM A297 / A297M-19 HP modified with niobium to resist nucleation and crack propagation by fatigue and creep mechanisms at elevated temperatures.
Digital-analog quantum computing of fermion-boson models in superconducting circuits

Published: November 2023

We propose a digital-analog quantum algorithm for simulating the Hubbard-Holstein model, describing strongly-correlated fermion-boson interactions, in a suitable architecture with superconducting circuits. It comprises a linear chain of qubits connected by resonators, emulating electron-electron (e-e) and electron-phonon (e-p) interactions, as well as fermion tunneling. Our approach is adequate for a digital-analog quantum computing (DAQC) of fermion-boson models including those described by the Hubbard-Holstein model. We show the reduction in the circuit depth of the DAQC algorithm, a sequence of digital steps and analog blocks, outperforming the purely digital approach. We exemplify the quantum simulation of a half-filling two-site Hubbard-Holstein model. In such example we obtain fidelities larger than 0.98, showing that our proposal is suitable to study the dynamical behavior of solid-state systems. Our proposal opens the door to computing complex systems for chemistry, materials, and high-energy physics.
Failure Analysis of a Martensitic Stainless Steel Steam Turbine Blade
Authors: Ruchert Cassius Olívio Figueiredo Terra , Carvalho Márcio
Published: November 2023

This work investigated the possible causes of premature failure of a steam turbine blade made from X20CrMo13 stainless steel. During their operation in power generation plants, the blades may suffer service failures that occur naturally or accelerated due to metallurgical or mechanical causes. In this work, one investigated the possible causes of the failure of a martensitic stainless steel turbine blade operating in a 25 MW turbine in a quenched and tempered cogeneration plant that fractured during operation. The results showed a martensitic structure with a delta ferrite content above 5%. Beach marks and fatigue striations were observed, arising from fatigue crack propagation. The tensile test showed an area reduction of 15%, probably due to carbide precipitation.

Bioinspired fluidic design for additive manufacturing
Authors: Shaqfeh Eric , Lipkowitz Gabriel , Krishna Navneeth , Coates Ian , DeSimone Joseph
Published: November 2023

While resin 3D printing affords designers unprecedented geometric complexity, currently the technology struggles to find real-world adoption in manufacturing settings due to slow print speeds, poor reliability, and cumbersome support structures. The last of these are not user-friendly in numerous ways; they are materially wasteful, human labor-intensive, time-consuming to remove, damaging to surface finish, and often unreliable in ensuring printability in the first place. These limitations are fundamentally related to adhesion forces and a lack of control of fluid flow during the printing process. Current design for additive manufacturing (DfAM) industry standards do not seek to offset such forces; instead, they empirically call for reducing printing speeds and/or imposing cumbersome supporting structures. Injection continuous liquid interface production (iCLIP) is a recent approach capable of effectively nullifying such forces by injecting resin into the deadzone. The method has been demonstrated to date for the case of a single channel running through an object formed of rigid material. However, the possibility of innervating the growing object with multiple channels -- possible to engineer into the CAD design uniquely for every print by this fabrication approach -- remains unexplored. Inspired by the complex three-dimensional fluidic distribution networks engineered by biological systems across scales, in this work we define and evaluate a qualitatively new bioinspired DfAM approach to accompany iCLIP, optimally innervating the part with channels to infuse resin into the deadzone. We detail our modeling approach for both single and multiple injection sites, and for Newtonian and non-Newtonian resins. After describing our hardware implementation to evaluate our approach, we provide experimental validation for our simulation-driven injection scheme, including using both rigid and elastomeric resins. We demonstrate such a bioinspired design approach can significantly increase print speed and reduce the need for supports in a user’s 3D model. In doing so, our approach promises to enhance the scalability of resin 3D printing to hasten its adoption in real-world manufacturing settings.
Deep Learning-driven Community Resilience Rating based on Intertwined Socio-Technical Systems Features
Authors: Mostafavi Ali , kai Yin
Published: November 2023

Community resilience is a complex and muti-faceted phenomenon that emerges from complex and nonlinear interactions among different socio-technical systems and their resilience properties. However, present studies on community resilience focus primarily on vulnerability assessment and utilize index-based approaches, with limited ability to capture heterogeneous features within community socio-technical systems and their nonlinear interactions in shaping robustness, redundancy, and resourcefulness components of resilience. To address this gap, this paper presents an integrated three-layer deep learning model for community resilience rating (called Resili-Net). Twelve measurable resilience features are specified and computed within community socio-technical systems (i.e., facilities, infrastructures, and society) related to three resilience components of robustness, redundancy, and resourcefulness. Using publicly accessible data from multiple metropolitan statistical areas in the United States, Resili-Netcharacterizes the resilience levels of spatial areas into five distinct levels. The interpretability of the model outcomes enables feature analysis for specifying the determinants of resilience in areas within each resilience level, allowing for the identification of specific resilience enhancement strategies. Changes in community resilience profiles under urban development patterns are further examined by changing the value of related socio-technical systems features. Also, combined resilience-risk levels in each community are analyzed, and several communities are found to suffer from high risk and low resilience, which calls for special attention to resilience enhancement. Departing from the dominantly vulnerability-focused assessments, Resili-Net enables characterizing community resilience as an emergent property arising from nonlinear interactions among heterogeneous community features related to their socio-technical systems. Accordingly, the outcomes provide novel perspectives for community resilience assessment by harnessing machine intelligence and heterogeneous urban big data.
Effectiveness of Initial Sources of Sexual and Reproductive Health Information among Adolescent Girls in Secondary Schools at Morogoro Municipality
Authors: Kishaluli Angel , Mollel Henry A.
Published: November 2023

Background
The initial source of Sexual and Reproductive Health (SRH) information is a fundamental determinant of how adolescent girls practice self-management. Adolescent girls are among the most vulnerable groups in society. Among the challenges they face are early pregnancies, unsafe abortions, school dropouts due to pregnancies, and sexually transmitted infections. Therefore, this study examined the effect of initial sources of SRH information on adolescent girls in Morogoro Municipality
Methods
A mixed-methods approach was applied in which case study design was used to examine the effectiveness of sexual and reproductive health information among adolescent girls in Morogoro Municipality. Data was collected through self-administered questionnaires among 88 adolescent girls and 12 in-depth interviews among 6 heads of schools and 6 female teachers. Descriptive statistics were used to assess sources of sexual and reproductive health information with the facilitation of Statistical Packages for Social science (SPSS). Qualitative data was analyzed through thematic analysis with the aid of computer software ATLAS.ti.
Results
From analysis the findings provided that the dominant initial sources of SRH information are mothers and slightly female teachers, church leaders and television programs. The overall mean behavioral practices score was low at 1.95 ± 2.24. Four behavioral practices were not practiced by the adolescent girls namely using pregnancy prevention techniques 68 (77%), carrying out sexual transmitted diseases testing 70 (79%), seeking and using HIV/AIDS guidance and counseling services them 71(81%) and seeking and using family planning guidance and counseling services 50 (56%). Lastly, the study found that the SRH information provided initially is unreliable 55 (63%), and does not reflect their age 57 (59%), hence ineffective in helping adolescent girls conduct self-management.
Conclusion
The study concludes that adolescent girls primarily rely on mothers for sexual and reproductive health (SRH) information, with some input from female teachers, church leaders, and television programs. However, they tend to overlook available HIV/AIDS guidance services due to unreliable and ineffective initial information. Improving the training of SRH information providers is crucial to enhance adolescent knowledge in this regard.
Cultural Psychology of Aesthetics: Art Viewing and Aesthetic Development in Iranian Culture

Published: November 2023

Why is it that some find art a prickly puzzle, others a yawning expanse, while others dive into its depths with vibrant joy? Some theorists have tried to quantify this diversity of art viewership. Famously, Housen made the case for five stages of aesthetic development: (a) accountive, (b) constructive, (c) classifying, (d) interpretive, and (e) re-creative. Here, we developed and validated a 17-item measure of aesthetic development that captures these stages. In a sample from Iran (N= 917), we showed how people’s scores on these stages correlate with personality traits and other art-related constructs. Specifically, we found that individuals with higher knowledge about art and more training in the arts tend to be at a more advanced stage of aesthetic development. People who score high on openness to experience also scored higher on more advanced aesthetic development stages. These results have implications for the quantitative studies of art and aesthetics in diverse cultures.

Authors: Reddy Somashekhara , N Thrimoorthy , G Kadiravan , M Thurai Pandian
Published: November 2023

Next-generation wireless networks will be designed via all-IP-based network framework that ensures seamless mobility and universal access to Internet via wireless networks. Also over the past few years, wireless network has gained its popularity due to its exorbitant volume and reasonable access cost. Despite its familiarity owing to the constraint in WLAN coverage, handover between nodes may cause elevated amount of handover failures. Seamless mobility is an empirical framework that seizes prevailing circumstances of what user or node is doing, with the objective that the users inclined services are said to be optimized. To develop a smart decision-making mechanism for seamless mobility and reducing energy consumption, deep learning-enabled reconfigurable wireless network solutions are required. In this work, a new method called, Chapman Kolmogorov and Deep Recurrent Network-based (CK-DRN) IoT data transmission in wireless network is introduced to validate handoffs in pragmatic frameworks. First, with the raw data obtained from IoT device network logs, Chapman Kolmogorov Poisson Taylor Optimum Beacon-based Route Discovery algorithm is designed with the objective of ensuring seamless mobility in an energy efficient manner. Second, Deep Recurrent Network-based Data Transmission is proposed that with the aid of concurrent utilization of the numerous paths initiates numerous subflow associations covering disjoint routes and transmits via the subflows, therefore ensuring greater amount of throughput. Simulation of CK-DRN achieves Direction of Arrival (DOA) and ID oriented Socket Layer (IoSL) in terms of delay, energy saving, and throughput.
Protective role of native root-associated bacterial consortium against root-knot nematode infection in susceptible plants

Published: November 2023

Root-knot nematode (RKN) is a global menace to agricultural crop production. The role of root-associated microbes (RAMs) in plant protection against RKN infection remains unclear. Here we observed that cucumber (highly susceptible to Meloidogyne incognita) exhibited a consistently lower susceptibility to M. incognita in the presence of native RAMs in three distinct soils. Nematode infection altered assembly of bacterial RAMs along the life cycle of M. incognita. Particularly, loss of bacterial diversity of RAMs exacerbated plant susceptibility to M. incognita. A diverse range of native bacterial strains isolated from M. incognita-infected roots had nematode-antagonistic activity. Increasing the number of native bacterial strains caused decreasing nematode infection, which was lowest when six or more bacterial strains were present. Multiple simplified synthetic communities consisting of six bacterial strains showed pronounced inhibitory effects on M. incognita infection in plants. These inhibitory effects were underpinned via multiple mechanisms including direct inhibition of infection, secretion of anti-nematode substances, and regulation of plant defense responses. This study highlights the role of native bacterial RAMs in plant resistance against RKNs and provides new insight into the development of a sustainable way to protect susceptible plants.

Published: November 2023

Full play of bolting anchorage performance can effectively improve the bolting effect of roadway surrounding rock and provide a strong guarantee for safety production of high yield and high efficiency mine. In the research, the mining roadway support situation of 8.0m super-high mining face in Bulianta Mine of Shendong Mining area is taken as the engineering background. Based on the theory of thick wall cylinder and laboratory experiment, the condition of anchoring surrounding rock is simulated, and the drawing experiment of anchor rod with three diameter matching and center degree isdone. By testing the parameters of drawing force, shear force and radial stress, the three-diameter matching relation of bolt support in Shendong mining area is determined, and the influence of anchor eccentricity on anchoring effect is revealed. Experimental results show that: the drawing force of anchor rod increases gradually the decrease of the ring thickness of resin anchoring agent,. Considering the site construction conditions, the resin ring thickness of Anchorage rod, drilling hole and anchorage three diameter matching in Shendong mining area should be 4~6mm. The anchoring performance varies obviously when anchor agent changes from 0 to 1, and the anchoring effect is the best when the centrality is 1.
A study on applying artificial intelligence and machine learning for modeling and predicting customer behaviors, churning and conversion
Authors: Kayyali Houssam
Published: November 2023

Digital companies have become an important provider of items, products, and services and they are increasingly replacing traditional markets. The growth of this business has created a heated competition among digital companies to extend their customer base and increase revenue. For this purpose, digital companies are now aware of the importance of gaining new customers and more importantly, maintaining existing customers as acquiring new customers is more expensive than retaining existing customers. That is why e-companies do their best to build strong bonds with their customers and support all efforts to predict possible churners and take proactive actions towards potential churners.
In this paper we will build a framework based on time-series Markov model that performs both potential churn customers prediction and predicts visitors who tend to exit from the e-company without making purchases. Markov model is a statistical model able to observe states in temporal patterns of data. Proposed model will be implemented on public dataset called “RecSys2015” and we will compare its results with other algorithms for benchmarking.
Combine MHD, chemical reaction, Slip effects and endoscopy analysis on couple stress fluid of particle-fluid suspension induced by peristaltic wave

Published: November 2023

This study delves into the intricate dynamics of fluid behavior within a peristaltic flow tube, specifically tailored for endoscopic applications. We examine the multifaceted influence of several critical factors, such as magnetic fields, porous media properties, heat transfer, chemical reaction ,slip conditions, and solid particles, on this fluid's flow. To simplify our analysis, we employ long-wavelength and low Reynolds number approximations to our mathematical models. Our findings are communicated through visual representations, illustrating their effects on key flow characteristics, including axial velocity, pressure gradients, heat transfer profiles, concentration profiles, and streamlines Our research not only deepens our understanding of peristaltic flows but also provides valuable insights to improve fluid transport in medical endoscopy, ultimately enhancing patient care and medical procedures. It is worth mentioning that as the magnetic field strength increases, the fluid velocity decreases. Conversely, when the pressure difference and particle velocity increase, and the couple stress parameters decrease, they boost fluid flow and lower the pressure difference.

Published: November 2023

Spike-timing dependent plasticity (STDP) is widely accepted as a mechanism through which the brain can learn information. Basing synaptic changes on the timing between spikes enhances contributing edges within a network. While STDP rules control the evolution of networks, most research focuses on spiking rates or specific activation paths when evaluating learned information. While imaging studies demonstrate physical changes to synapses due to STDP, these changes have not been interrogated based on their embedding capacity of a stimulus .Here, we show that networks with biological features can embed stimulus information into their synaptic weights. We use a k-nearest neighbor algorithm on the synaptic weights of independent networks to identify their stimulus with high accuracy based on local neighborhoods.While spike rates and timings remain useful, structural embeddings represent a new way to integrate information within a biological network. Our results demonstrate that there may be value in observing these changes directly.Beyond computational applications, this analysis may also inform investigation into neuroscience.Research is underway on the potential of astrocytes to integrate synapses in the brain and communicate that information elsewhere.In addition, observations of these synaptic embeddings may lead to novel therapies for memory disorders, such as transient epileptic amnesia.

Penile prosthesis (PP) in Peyronie’s disease (PD) is considered only when pharmacotherapy has failed in management of erectile dysfunction (ED). Patients with PD who underwent PP (malleable or inflatable) with or without additional maneuvers like manual modeling and grafting from 2012 to 2022 were included in the study. Patient and partner satisfaction were assessed using a 5-point Likert scale. ED was assessed using a validated questionnaire. A total of 168/636 patients underwent PP as first-line surgical management for PD and were included in the study. The mean age was 56.3 years +/- 12.4 and a median BMI of 27.2. Mean follow-up was 56 months (95% CI: 11-21). All 168 patients had undergone additional maneuvers such as manual modeling in 85.7% and grafting in 14.3%. Majority of the patients underwent a 3-piece inflatable PP (86.9%). Thirty-three (19.7%) PD patients without ED had undergone PP. The satisfaction of PD patients with ED and without ED was not statistically different (88.9% vs 87.9%). If surgery is offered in PD, PP may be considered as a first-line surgical treatment regardless of the ED in view of the acceptable complications and high satisfaction rates.
Numerical study of the dynamic behavior of a group of piles in sloping ground

Published: November 2023

In recent years, the use of piles in important structures such as power plant equipment, petrochemical complexes, marine structures, and bridges has significantly expanded. The safe and economical design of these types of piles under lateral dynamic loads is of special importance. Considering the complex interaction between the pile and the soil, along with the effects resulting from seismic forces, the need for the use of numerical methods to investigate and understand this issue is strongly felt. In this study, the behavior of a pile group in sloping ground under dynamic loads has been investigated using Abaqus software. The parameter under study is the slope angle, which, by varying it, the dynamic behavior of the pile group has been examined, and the results are reported in terms of shear force and bending moment along the piles. The results indicate that with an increase in the slope, the amount of shear force and bending moment created in the piles also increases. Additionally, with an increase in the slope angle, the forces generated in the piles exhibit an irregular trend.

Background:
With over half a million new tuberculosis (TB) cases surfacing each year, Pakistan is among the 30 high TB burden countries. Being deeply underfunded in its fight against TB, much of the awareness among the general population comes from the healthcare workers (HCWs) who are at risk of acquiring nosocomial infection. Thus, this research aims to assess TB's knowledge, attitude, and practice (KAP) among HCWs in Karachi, Pakistan.
Methods:
An institution-based cross-sectional survey was conducted in nine hospitals providing TB services in Karachi, Pakistan, using an anonymous, self-administered questionnaire. Three hundred eighty-four responses from HCWs were assessed for their knowledge, attitudes, and practices on TB infection control.
Results:
The knowledge of TB infection control among almost half (45.8%) of HCWs was poor and much poorer among administration and lower-level staff. The knowledge level was significantly associated with educational status and TB training and orientation received. The majority (73.2%) of HCWs were positive about TB infection control. Sixty-five percent of HCWs were found to be concerned about being infected with TB. The use of respirators among the HCWs was limited, and triage of TB suspects was also lacking.
Conclusions:
The results revealed some knowledge gaps and poor practices among healthcare workers regarding TB. Therefore, health professionals must undergo periodic training customized to their needs.

Thyroid storm during pregnancy is a rare but potentially life-threatening condition that poses significant challenges for both maternal and fetal health. We present a case report of a 29-year-old pregnant woman who experienced thyroid storm during the third trimester. The clinical presentation, diagnostic challenges, and management strategies are discussed. This case underscores the importance of vigilance in monitoring thyroid function during pregnancy and prompt intervention to optimize outcomes.
Continuous flow synthesis of meso-substituted porphyrins with inline UV-Vis analysis

Published: November 2023

Porphyrin derivatives have found diverse applications due to their attractive photophysical and catalytic properties, but remain challenging to synthesize, particularly at scale. Porphyrin synthesis thus stands to benefit from the more controlled environment, opportunities for efficient optimization, and potential for scale-up available in flow. Here, we have transferred Lindsey porphyrin synthesis into flow, enabling controlled timing for oxidation and neutralization steps and real time monitoring of the reaction mixture with inline UV-Vis analysis. For tetraphenyl porphyrin (TPP), inline UV-Vis showed the presence of protonated TPP, formed due to residual acid catalyst. Thus, inline monitoring allowed optimization of the neutralization step to improve yield. Three further porphyrin substrates were produced in flow; in two cases, the yield from inline UV was significantly higher than the yield from post-purification, identifying further yield losses that could be recovered by modifying the purification step. The workflow presented here can be adapted to multiple substrates to systematically optimise porphyrin yield, reducing the time needed to develop scalable routes to these valuable compounds.

Published: November 2023

Background: Patient Safety (PS) is a critical healthcare service issue. Sleep disorders not only cause health problems for nursing students but also lead to decreased performance and increased incidence of medication errors, which can endanger patient safety.
Objectives: This study aimed to investigate the predictors of Patient Safety Competency (PSC) based on the sleep quality of nursing students.
Methods: This descriptive-analytical cross-sectional study was conducted on 331 Ardabil School of Nursing and Midwifery students. The participants were selected by stratified random sampling. Data were collected using a demographic information form, the Pittsburgh Sleep Quality Index (PSQI), and the Health Professional Education in Patient Safety Survey (H-PEPSS). The collected data were analyzed using descriptive and inferential statistical methods.
Results: The nurses’ patient safety competency in the classroom and clinical settings was at an average level. Teamwork with other healthcare professionals scored the lowest. Also, sleep quality dimensions were predictors of PSC in nursing students.
Conclusion: Most nursing students typically have an average PSC, and there is a clear positive correlation between sleep quality and PSC. Therefore, it becomes imperative to identify the key factors that directly impact PSC. Armed with this knowledge, the managers of the Nursing and Midwifery School can proactively take measures to enhance both the classroom and clinical environments. Furthermore, organizing informative and engaging sleep quality workshops can significantly improve patient care quality.
