Simulation and Characterization of Micro-Discharge Phenomena Induced by Glitch Micro-Defects on an Insulated Pull Rod Surface

The reliability of GIS (gas-insulated switchgear) circuit breakers significantly depends on the condition of the insulated pull rods, with micro-defects on their surface posing a potential risk for micro-discharges and breakdown incidents. Experimentally investigating these micro-discharges is challenging due to their minute nature. This study introduces a framework to examine the linkage between micro-defects and micro-discharges, coupled with numerical simulations of the micro-discharge process in insulated pull rods afflicted by surface infiltration flaws under operational conditions. Initially, samples containing micro-defects were sectioned via water jet cutting for microstructural analysis through white light interferometry. Subsequently, a two-dimensional axisymmetric model simulating positive corona discharge from a needle to a plate electrode was employed to derive the relationship between charged particle density and the electric field in SF6 and air. Building on these observations, a micro-discharge model specific to micro-defects was developed. Comparative analysis of micro-discharge behaviors in SF6 and air for identical defect types was conducted. This research framework elucidates the discharge dynamics of charged particles in SF6 and air during micro-discharge events, shedding light on the mechanisms underpinning micro-discharges triggered by insulation rod defects.

Exploring the Potential Role of Lactobacillus plantarum in the Reversal of Induced Cognitive Long-term Memory Impairment

Long-term Memory (LTM) is formed by sequential changes in the different brain regions due to synaptic plasticity changes. This synaptic plasticity changes formed in the brain due to the acquittance of unexposed information and its retrieval due to learning and memory formation (LMF). In a normal condition, LMF uses RNA and protein synthesis machinery to form LTM, which lasts till the end of an organism's lifetime. Formed LTM shows sequential changes happening in the presynaptic and postsynaptic neurons. Stated sequential changes are initiated when the released neurotransmitter binds with the postsynaptic neuronal receptors and activates the brain's ERK - CREB neuronal signaling pathway. Based on the previous findings, the present study was designed to study the interrelationship between cognitive impairment and oral/gut dysbiosis with the help of a probiotic strain (Lactobacillus plantarum). Two phases of behavioural analysis (first and second phase) were used to identify the effect of oral microbial infusions on impaired LTM formation and its reversal using restoration of dysbiosed gut/oral microbiota. The first phase of behavioural analysis (FPBA) reported that oral microbial infusion plays a major role in developing oral/gut dysbiosis, which results in impaired cognitive functions. Further, formed oral/gut microbiota dysbiosis was reversed with the help of probiotic strain in the second phase of behavioural analysis (SPBA). Thus, a comparative two-phase behavioural analysis revealed that probiotics may play a significant role in reversing induced cognitive decline. The outcome of the present study also proved that probiotic treatment might play a major role in the reversal of dysbiosed microbiota in the oral cavity and the gut.

Comparative analysis of nonlinear dynamic behaviors of hyperelastic curved structure modelled by different constitutive laws

This work focuses on conducting numerical studies and comparisons on the nonlinear dynamic behaviors of hyperelastic curved structures subjected to external dynamic loadings. A numerical model of the hyperelastic structure is developed using the nonlinear finite element method, which considers both the geometric nonlinearity resulting from large deformations and the material nonlinearity due to hyperelasticity. Four commonly used hyperelastic constitutive laws, namely the Mooney-Rivlin model, the neo-Hookean model, the Yeoh model, and the Ogden model, are employed to describe the nonlinear stress-strain relationship of the hyperelastic material. The convergence performance of the numerical model with respect to grid element and time step is thoroughly examined through several numerical examples. Subsequently, based on the developed numerical model, the nonlinear dynamic behaviors of the hyperelastic curved structures excited by uniform pressure loadings with single and dual frequencies are studied and compared using various constitutive laws. The material constants used in these constitutive laws are estimated based on the well-known Treloar's test data on vulcanized rubber material. Additionally, comprehensive parametric analyses are conducted on the nonlinear dynamic behaviors of the hyperelastic structure simulated by different constitutive laws. The deformation evolution process, resonance curves, time-frequency analysis, bifurcation diagrams, and phase portraits are employed to demonstrate the similarities and differences in the nonlinear dynamic behaviors (i.e., super- and sub-harmonic resonance, internal resonance, chaotic motion and bifurcations) of the hyperelastic structure modeled by different constitutive laws.

Role of Probiotic Strain Lactobacillus acidophilus in the Reversal of Gut Dysbiosis Induced Brain Cognitive Decline

In the central nervous system, bidirectional communication between the brain and gut results in memory formation due to synaptic plasticity changes. During a healthy state, oral balanced microflora plays a pivotal role in memory formation by inhibiting the enterotoxin level produced by infectious pathogens. In disease conditions, beneficial microbial dysbiosis may result in excess enterotoxin production. Further, excess enterotoxin secretion prevents beneficial bacteria's proliferation and impairs neurotransmitter precursor compounds' transport to the brain. Blockade of neurotransmitter precursor compounds may result in the development of memory loss. The present study stated the role of Lactobacillus acidophilus in recovering memory loss. Reversal of cognitive impairment is shown with the help of a three-step behavioural analysis, which consists of one pre-infusive behavioural analysis and two post-infusive behavioural analyses (phase 1 and 2). The pre-infusive analysis showed no cognitive impairment in an assimilated environment without any infusions. After oral microbial infusions, phase 1 of post-infusive behavioural analysis showed the presence of cognitive impairment in the experimental groups who received oral infusions. Formed cognitive impairment is reverted with the help of L. acidophilus oral infusion in phase 2 of post-infusive analysis. Comparative three-step behavioural analysis proved that Pseudomonas aeuroginosa induced cognitive impairment may revert to normal conditions with the help of L. acidophilus. The outcome of the present study proves that cognitive impairment developed due to poor oral hygiene can be treated with the help of probiotic microorganisms.

The results of the study indicated that, according to gender, there is a significant relationship between gender and intention to leave the job in favor of men, the intention to leave a job for men was significantly lower than for women, according to educational status, the devotional work behavior of graduate higher than university. In addition, there is a moderate negative relationship between devotional work behavior and the intention to leave the job.

Comparative analysis of locomotor behavior and head diurnal transcriptome regulation by PERIOD and CRY2 in the diamondback moth.

Earth's rotation shapes a 24-h cycle, governing circadian rhythms in organisms. In mammals, the core clock genes, CLOCK and BMAL1, are regulated by PERIODs (PERs) and CRYPTOCHROMEs (CRYs), but their roles remain unclear in the diamondback moth, Plutella xylostella. To explore this, we studied P.xylostella, which possesses a simplified circadian system compared to mammals. In P.xylostella, we observed rhythmic expressions of the Pxper and Pxcry2 genes in their heads, with differing phases. In vitro experiments revealed that PxCRY2 repressed monarch butterfly CLK:BMAL1 transcriptional activation, while PxPER and other CRY-like proteins did not. However, PxPER showed an inhibitory effect on PxCLK/PxCYCLE. Using CRISPR/Cas9, we individually and in combination knocked out Pxper and Pxcry2, then conducted gene function studies and circadian transcriptome sequencing. Loss of either Pxper or Pxcry2 eliminated the activity peak after lights-off in light-dark cycles, and Pxcry2 loss reduced overall activity. Pxcry2 was crucial for maintaining endogenous rhythms in constant darkness. Under light-dark conditions, 1 098 genes exhibited rhythmic expression in wild-type P.xylostella heads, with 749 relying on Pxper and Pxcry2 for their rhythms. Most core clock genes lost their rhythmicity in Pxper and Pxcry2 mutants, while Pxcry2 sustained rhythmic expression, albeit with reduced amplitude and altered phase. Additionally, rhythmic genes were linked to biological processes like the spliceosome and Toll signaling pathway, with these rhythms depending on Pxper or Pxcry2 function. In summary, our study unveils differences in circadian rhythm regulation by Pxper and Pxcry2 in P.xylostella. This provides a valuable model for understanding circadian clock regulation in nocturnal animals.

Explorando la neofobia alimentaria en ratones: descifrando el comportamiento e implicaciones para la investigación en laboratorio

Food neophobia refers to avoiding foods to which the subject has not been exposed. This phenomenon influences food preference and intake. Other conditions that directly affect food consumption are inflammatory diseases such as neurological and respiratory illnesses. This study made a comparative analysis of exploratory behavior in BALB/c mice under healthy (intact control) and unhealthy conditions (i.p. lipopolysaccharide administration). Additionally, the investigation aimed to examine mice's inclination towards sweet flavors in both healthy and unhealthy states. Lastly, the study evaluated the preference for sweet and salty flavors alongside standard food in healthy mice by measuring behavioral variables such as distance traveled, average speed and frequency. Behavioral tests were performed on the mice, recorded, and analyzed with specialized software. The data were processed and analyzed, the Kolmogorov-Smirnov test and a Tukey post hoc test were performed. The results suggest that flavor perception plays a critical role in the feeding behavior of mice, particularly sweet taste (p<0.0001). It was found that there are anxiety-like behaviors when exposed for the first time to snacks associated with said flavor. The methodology used and the results obtained are beneficial for evaluating the function of taste in rodents since stimulus-response interactions must be considered in behavioral tests.

Comparative Analysis of Tribological Behavior in Aluminum Matrix Composites Incorporating Fe75Si15Zr5B5 Metallic Glass and SiC Particles

In this study, a comparative investigation was conducted to assess the impact of Fe-based metallic glass (FMG) and silicon carbide (SiC) reinforcing particles on the tribological properties of aluminum matrix composites. The composites were synthesized using the powder metallurgy method, and subsequent dry sliding wear tests were performed by a pin-on-disc machine at ambient temperature. Thorough examinations of the microstructure, mechanical properties, and densification behavior were carried out for the developed composites, and these findings were then correlated with their wear performance. To gain insights into the wear mechanisms, comprehensive characterizations of the worn surfaces and debris were conducted utilizing field-emission scanning electron microscopy (FESEM) and energy-dispersive spectroscopy (EDS) analysis. The outcomes of the dry sliding tests revealed that, in contrast to SiC, the addition of FMG reinforcing particles significantly decreased the friction coefficient while concurrently enhancing the wear resistance of the aluminum matrix. The microstructural investigations divulged that the pure aluminum sample experienced severe abrasive and adhesive wear mechanisms, which were effectively mitigated through the incorporation of FMG particles, due to the formation of an oxide tribolayer in the composite during the wear test. Conversely, the SiC-reinforced composites exhibited a dominant wear mechanism characterized by severe delamination, which consequently contributed to their elevated wear rate. These findings shed light on the distinct effects of FMG and SiC particles on the tribological properties of aluminum matrix composites, providing valuable insights for potential applications in engineering and industrial sectors, particularly in scenarios involving metal-to-metal contact.

A Comparative Analysis of Seismic Behavior of Regular and Irregular Shaped Buildings with OMRF and SMRF Structural Systems: A Review

Abstract: These days, modern residential buildings are getting higher and higher. The way these structures perform is significantly impacted by the impact of lateral loads from wind and earthquakes. It is impossible to completely prevent irregularities when building. It is mandatory to investigate how these irregularly shaped structures behave during earthquakes. The behaviour of regular and irregular buildings is represented in this study. As a result of the irregular plan and elevation configurations of various buildings in the current situation, which could be subject to hazadous earthquakes in the future, it is necessary to assess how well the structures are performing in terms of their ability to withstand disasters, primarily earthquakes. This project aims to compare the seismic behaviour of regular-shaped buildings with OMRF and SMRF structural systems versus. The study will make use of STAAD-Pro software, and the buildings' performance will be evaluated according to several criteria. The results of the research will broaden our understanding of earthquake engineering and provide insight into the performance of OMRF and SMRF structural systems in both regularly shaped and irregularly shaped buildings.

Kinematic Solutions and Bifurcation Analysis of Single Vertex Origami Pattern

The bifurcation behavior of deployable structures has received significant attention from different fields. Apart from pin-jointed structures, origami, as a thriving inspiration for valuable and practical deployable structures, develops singular configurations along its kinematic paths. The kinematic behaviors of single vertex origami patterns are studied in this work. General four-crease patterns and symmetric six-crease patterns are thoroughly investigated based on the analytical solutions obtained by constraint equations. Moreover, the corresponding motion paths are described to discuss the bifurcation behavior. A comparative analysis of kinematic behaviors with the different actuating coordinates is performed. Three types of bifurcation are analyzed, concluding that three different motion paths cannot occur at the same time. The research findings of the present work can contribute to the development of novel deployable structures and mechanical systems.

A comparative analysis of depressive-like behavior: Exploring sex-related differences and insights.

Profiling the variability related to the estrous cycle is essential for assessing depressive-like behavior and screening drugs. This study compares circulating plasma corticosterone levels [CORT] and behavioral alterations in mice exposed to sucrose preference, forced swimming, and tail suspension tests (SPT, FST, and TST, respectively). While SPT exposure did not significantly alter [CORT], FST and TST showed notable changes. Mice in the TST exhibited increased movement and decreased immobility time compared to FST, suggesting a lower likelihood of depressive-like behavior in male mice. Notably, during the proestrus phase, female mice displayed the highest tendency for depressive-like behavior and elevated [CORT], but similar response to antidepressants (imipramine and fluoxetine). The inherent stress of the FST and TST tasks appears to influence [CORT] as well as depressant and antidepressant effects. These comparisons provide valuable insights for further behavioral phenotyping, model sensitivity assessment, and deepen our neurobiological understanding of depression in the context of drug screening.

Schumpeter Lecture 2023: Rationality and Zero Risk

Abstract We adopt a definition of “rationality” as robustness to analysis: A mode of behavior is rational for a decision maker if she feels comfortable with it once it has been analyzed and explained to her. With this definition in mind, is it irrational to violate continuity axioms in one’s stated preferences? Specifically, does it make sense to avoid any positive probability of a negative outcome, no matter how small? Or, if a decision maker states such a “zero risk” policy, does she mean what she says? We propose to study this question axiomatically, asking which modes of behavior correspond to such statements. The baseline model evaluates a lottery by its expected utility and an extra additive term that measures the cost of deviating from a “zero risk” choice. A generalized version allows for multiple sets of principles, where the cost of risking a set of principles is added to the expected utility of a lottery. Stronger assumptions imply that the cost of violating a set of principles is additive in the individual costs. We develop a comparative behavioral analysis that allows making interpersonal comparisons about the relative importance of principles.

A comparative scientometric analysis of investor sentiment and trading behaviour research

The purpose of this study is to conduct a comparative analysis of investor sentiment and trading behavior in the field of behavioral finance. This study analyzes and compares the research evolution within these two domains using various scientometric analysis methods. The analysis reveals that the number of publications in the field of investor sentiment has grown exponentially while research activity in trading behavior has slowed down in recent years. Investor sentiment research has attracted more attention and generated more publications despite a relatively late start. The USA and China are the major countries conducting research in these two fields and the research output is primarily derived from economically developed regions. Investor sentiment and trading behavior research shows a convergence trend with common research hotspots including COVID-19, Bitcoin and machine learning. Both fields are concentrated in financial market research and have emerging research frontiers such as financial crises, social media and cryptocurrencies. Highly cited articles indicate a degree of overlap between the two fields wherein the domain of trading behavior is predominantly linked to investor sentiment. This study provides valuable insights into the research progress on investor sentiment and trading behavior.

Comparative analysis of lifestyle behaviors and dietary intake among obese and non-obese individuals following bariatric surgery: a secondary data analysis from 2020 to 2022

ObjectiveThe aim of this research is to perform a comparative examination of lifestyle habits and dietary consumption between obese and non-obese subjects who have undergone bariatric surgery. This is done with the intent of investigating the disparities in obesity outcomes attributable to these elements.MethodThis study involves a secondary analysis of cross-sectional data obtained from the Sharik Diet and Health National Survey (SDHNS). To ensure a representative distribution of participants, the SDHNS employs a proportional quota sampling strategy, with stratification based on age, sex, and geographic location within Saudi Arabia’s 13 administrative regions, utilizing the ZDataCloud® system for this purpose. The data, collected between 2020 and 2022 from over 15,000 participants, were screened to identify the eligible records of individuals who underwent bariatric surgery.ResultsWithin the entire sample, a mere 5.0% (806 individuals) had undertook bariatric surgery, with females comprising 54% of this specific subgroup. The average age within this group was 38.85 years (SD 13.02) and range (18–87). Post-operative results showed that 33% of these individuals remained classified as obese. Utilizing the backward likelihood ratio regression model, it was determined that factors including age, decreased consumption of fresh juices and chicken, as well as current tobacco use, were significantly associated with persistent obesity.ConclusionThe findings of this study suggest an association between the non-obese group and healthier lifestyle choices, including the consumption of high-protein diets and fresh juices, alongside a decreased prevalence of smoking. These observations underscore the significance of maintaining a healthy lifestyle for positive weight loss outcomes following bariatric surgery.

Zebrafish gonad mutant models reveal neuroendocrine mechanisms of brain sexual dimorphism and male mating behaviors of different brain regions

BackgroundSexually dimorphic mating behaviors differ between sexes and involve gonadal hormones and possibly sexually dimorphic gene expression in the brain. However, the associations among the brain, gonad, and sexual behavior in teleosts are still unclear. Here, we utilized germ cells-free tdrd12 knockout (KO) zebrafish, and steroid synthesis enzyme cyp17a1-deficient zebrafish to investigate the differences and interplays in the brain–gonad–behavior axis, and the molecular control of brain dimorphism and male mating behaviors.MethodsTdrd12+/−; cyp17a1+/− double heterozygous parents were crossed to obtain tdrd12−/−; cyp17a1+/+ (tdrd12 KO), tdrd12+/+; cyp17a1−/− (cyp17a1 KO), and tdrd12−/−; cyp17a1−/− (double KO) homozygous progenies. Comparative analysis of mating behaviors were evaluated using Viewpoint zebrafish tracking software and sexual traits were thoroughly characterized based on anatomical and histological experiments in these KOs and wild types. The steroid hormone levels (testosterone, 11-ketotestosterone and 17β-estradiol) in the brains, gonads, and serum were measured using ELISA kits. To achieve a higher resolution view of the differences in region-specific expression patterns of the brain, the brains of these KOs, and control male and female fish were dissected into three regions: the forebrain, midbrain, and hindbrain for transcriptomic analysis.ResultsQualitative analysis of mating behaviors demonstrated that tdrd12−/− fish behaved in the same manner as wild-type males to trigger oviposition behavior, while cyp17a1−/− and double knockout (KO) fish did not exhibit these behaviors. Based on the observation of sex characteristics, mating behaviors and hormone levels in these mutants, we found that the maintenance of secondary sex characteristics and male mating behavior did not depend on the presence of germ cells; rather, they depended mainly on the 11-ketotestosterone and testosterone levels secreted into the brain–gonad regulatory axis. RNA-seq analysis of different brain regions revealed that the brain transcript profile of tdrd12−/− fish was similar to that of wild-type males, especially in the forebrain and midbrain. However, the brain transcript profiles of cyp17a1−/− and double KO fish were distinct from those of wild-type males and were partially biased towards the expression pattern of the female brain. Our results revealed important candidate genes and signaling pathways, such as synaptic signaling/neurotransmission, MAPK signaling, and steroid hormone pathways, that shape brain dimorphism and modulate male mating behavior in zebrafish.ConclusionsOur results provide comprehensive analyses and new insights regarding the endogenous interactions in the brain–gonad–behavior axis. Moreover, this study revealed the crucial candidate genes and neural signaling pathways of different brain regions that are involved in modulating brain dimorphism and male mating behavior in zebrafish, which would significantly light up the understanding the neuroendocrine and molecular mechanisms modulating brain dimorphism and male mating behavior in zebrafish and other teleost fish.Graphical

Comparative analysis of triboelectric behavior of natural waste biomaterials and green energy harvesting

This study examines the triboelectric behavior of fibers that are readily available and were obtained from the bombax ceiba tree (BOM) and the calotropis plant (CALO). A triboelectric nanogenerator (TENG) is fabricated from these fibers as charge-generating layers that produce a charge by contact electrification. The properties of these fibers which include surface morphology and crystallographic nature are examined using different characterization techniques. Scanning electron microscopy images reflect more roughness in CALO as compared to BOM whereas both materials show an almost amorphous nature in X-ray diffraction data. Further, both materials show tribopositive nature when tested against polytetrafluoroethylene (PTFE) and nylon. While examining their electrical performance, the CALO–PTFE pair produced 11.1 V while 10.7 V is generated from the BOM–PTFE pair. These combinations are capable of illuminating multiple light-emitting diodes of the green spectrum and can derive one digital calculator. Lastly, the dependency of TENG performance on the contact area of active layers is analyzed. From the results obtained, it is concluded that these materials can potentially power small electronic gadgets and can contribute to the growth of a sustainable civilization.

Comparative analysis of filterability behavior of B30 and B40 biodiesel blends on various porosity and dimension of fuel filter

This report is focused on comparative analysis of the impact of using biodiesel blends containing more than 30% biodiesel in diesel engine filtration systems. The objective of this study is to support the sustainability of the mandatory biodiesel utilization program by more than 30%. To evaluate filterability behavior of high-percentage biodiesel blends, namely B30 and B40 (30 and 40%-vol biodiesel on diesel fuel), the study employed the ASTM D 2068 Filter Blocking Tendency (FBT). After filter rig test, fuel filter pressure was also evaluated using the JIS 1617 standard method. It is important to note that fuel filter plays an important role in removing contaminants from fuel, and, hence, the effect of the difference in filter porosity needs to be observed with pressure difference across fuel filter monitored at the flow rate (0.03 m3/h and fuel temperature (15 ⁰C and 25 ⁰C). Furthermore, the effect of changes in temperature and surface morphology on the characteristics of filter was observed in this study. Based on FBT analysis, a polynomial regression (R2 > 0.98) was used to describe the relationship between FBT value and the effect of biodiesel blends on filterability. It was concluded that the temperature, monoglyceride content, and FAME concentration in the diesel fuel influenced their FBT. However, the rise in waxy particles at 15oC (near Cloud Point) could result in a more significant average pressure drop than at 25⁰C (ambient temperature). It was also found that a higher biodiesel mixture potentially results in a higher-pressure difference due to the lower fuel temperature and the formation of waxy contaminants that can clog filter.

The Role of Destination Image in Influencing Tourist Behaviors and Experiences: A Comparative Study of the Greek Islands versus Mainland Destinations

This research delved into the significance of destination image in shaping tourist behaviors and experiences, through a comparative study between the Greek Islands and mainland destinations. Previous literature provided substantial groundwork for understanding the concept of destination image and its correlation with tourist behavior. A comprehensive review of numerous scholarly articles, journals, and books was undertaken to identify the core elements contributing to destination image, such as natural resources, cultural heritage, hospitality, and tourist facilities. The study highlighted the crucial role of destination image as a determinant of tourist satisfaction, which, in turn, influenced behavioral intentions like word-of-mouth promotion and revisits. The analysis was bifurcated into two sections, representing the Greek Islands and the mainland, with each section examining distinct aspects of these diverse environments. Findings from the literature revealed a more romantic and adventurous image associated with the Greek Islands, rooted in their unique cultural attributes, beautiful landscapes, and laid-back lifestyle. This image was found to stimulate tourist activities related to relaxation, exploration, and cultural immersion. In contrast, mainland Greece, rich in history, architecture, and tradition, was perceived as more educational and historical. Tourists here were likely to engage in activities like museum visits, city tours, and archaeological explorations. Discrepancies in tourist behaviors and experiences in the two regions underlined the powerful influence of destination image. While both regions attracted tourists, their behaviors and experiences differed based on the respective destination images. This research has filled an academic gap by providing a comparative analysis of tourist behaviors and experiences influenced by the destination image between the Greek Islands and mainland Greece. It also offers practical insights to tourism planners and marketers in these regions, emphasizing the need for destination marketing strategies that accurately reflect and capitalize on their distinct destination images.
