Abstract
Air Quality Monitoring and Control System is a method of monitoring and controlling air quality in an area or place where air contamination may occur in an activity or work. In this case, the Air Quality Monitoring and Control System is applied to the welding habitat or the welding house in the system pipe welding process. At this time, the welding habitat in the welding pipe pipeline system with the shielding gas process has not been monitored and controlled for air quality during the welding process, this condition causes the welder in the welding habitat to become uncomfortable which can affect the quality of the welding and endanger the welder's health. For this reason, an air quality monitoring and control system is needed that can unite and control the air quality in the welding habitat during the welding process. The purpose of the design of this Air Quality Monitoring and Control System is to make the welding process in the welding habitat of the system pipe welding process more comfortable and safer for the welder's health. So that the welder can concentrate fully on the welding process and produce good and quality welding production. With the application of this system, it can provide a level of weld repair that can reduce welding repair costs incurred by the Company.

Utafiti huu ulinuia kuchanganua usimilishaji wa ishara za isimu katika breili ya Kiswahili. Uchanganuzi huu ulitiwa hamasa na mambo matano muhimu. Kwanza, breili ndio njia ya pekee ya uandishi ambayo watu wasioona hutumia katika mawasiliano na usomi wao. Vilevile, kutokuwepo kwa kipengele muhimu cha matamshi katika kamusi za breili na vitabu vya sarufi hasa vya sekondari. Jambo jingine ni kwamba, wanafunzi wanaotumia breili hupewa maswali mbadala wakati wanapotahiniwa katika maeneo ya fonolojia, mofolojia, na hata katika uchanganuzi wa sentensi. Aidha, kutokuwepo kwa ishara bainifu za isimu katika maandishi ya breili ya Kiswahili. Kichocheo cha mwisho, praima mbili za breili ya Kiswahili: ya 1978 na 1995 zinazotumiwa Afrika Mashariki hazina ishara za kiisimu. Utafiti huu ulikusudia kujibu maswali yafuatayo: changamoto zipi zinazozuia usimilishaji wa ishara za kiisimu katika breili ya Kiswahili? Rasimu za Kiingereza na Kiswahili huathiriana kwa njia zipi? Ukosefu wa ishara za isimu katika breili huathiri ufundishaji wa isimu kwa njia gani? Na mwisho, mikato ya Kiswahili na ya Kiingereza inayotumia nukta zinazofanana huathiri uchapishaji wa vitabu vya isimu kwa njia zipi? Utafiti huu ulilenga kutimiza malengo yafuatayo – kwanza, kubainisha na kutatua changamoto zinazozuia usimilishaji wa ishara za isimu katika breili ya Kiswahili. Pili, Kuchanganua rasimu ya Kiingereza na ya Kiswahili. Aidha, kuchunguza athari ya ukosefu wa ishara hizi katika ufundishaji wa isimu. Mwisho, kutathmini athari ya matumizi ya mikato inayotumia nukta zinazofanana katika uchapishaji wa vitabu vya isimu. Makala haya yameshughulikia vikwazo vya usimilishaji wa ishara za isimu katika breili. Mtafiti alitumia mbinu ya mahojiano katika kukusanya dataUtafiti huu ulichanganua usimilishaji wa ishara hizi kwa kuzingatia nadharia ya usomaji na uandishi wa breili iliyoasisiwa na Kizuka na Fuji (2005).

Age-dependent changes in the anger superiority effect: Evidence from a visual search task
Authors: Ceccarini Francesco , Colpizzi Ilaria , Caudek Corrado 
Published: January 2024

AbstractThe perception of threatening facial expressions is a critical skill necessary for detecting the emotional states of others and responding appropriately. The anger superiority effect hypothesis suggests that individuals are better at processing and identifying angry faces compared with other nonthreatening facial expressions. In adults, the anger superiority effect is present even after controlling for the bottom-up visual saliency, and when ecologically valid stimuli are used. However, it is as yet unclear whether this effect is present in children. To fill this gap, we tested the anger superiority effect in children ages 6–14 years in a visual search task by using emotional dynamic stimuli and equating the visual salience of target and distractors. The results suggest that in childhood, the angry superiority effect consists of improved accuracy in detecting angry faces, while in adolescence, the ability to discriminate angry faces undergoes further development, enabling faster and more accurate threat detection.

Published: January 2024

Abstract
Human beings display the extraordinary ability of grasping and communicating abstract concepts. Yet, no standardized instruments exist to assess this ability. Developing these tools is paramount for understanding abstract representations such as social concepts, with ramifications in educational and clinical settings. Here, we developed an image database depicting abstract social concepts varying in social desirability. We first validated the image database in a sample of neurotypical participants. Then, we applied the database to test different hypotheses regarding how social concepts are represented across samples of adults and children with autism spectrum condition (ASC). Relative to the neurotypicals, we did not observe differences related to ASC in identification performance of the social desirability of the concepts, nor differences in metacognitive ability. However, we observed a preference bias away from prosocial concepts that was linked to individual autistic traits in the neurotypicals, and higher in ASC relative to the neurotypicals both in adults and children. These results indicate that abstract representations such as social concepts are dependent on individual neurodevelopmental traits. The image database thus provides a standardized assessment tool for investigating the representation of abstract social concepts in the fields of psycholinguistics, neuropsychology, neuropsychiatry, and cognitive neuroscience, across different cultures and languages.

Знайдено конструктивні необхідні та достатні умови розв'язності і схему побудови розв'язків неавтономної нелінійної періодичної крайової задачі для рівняння типу Релея, не розв'язаного відносно похідної. Актуальність дослідження неавтономних крайових задач, не розв'язаних відносно похідної, пов'язана з тим, що вивчення традиційних задач, розв'язаних відносно похідної, іноді ускладнюється, наприклад у випадку отримання нелінійностей, не інтегровних в елементарних функціях. У статті розглянуто критичний випадок, коли рівняння для породжуючих амплітуд слабконелінійної періодичної крайової задачі для рівняння типу Релея не перетворюється на тотожність. Для знаходження конструктивних умов розв'язності та збіжних ітераційних схем побудови наближених розв'язків неавтономної нелінійної крайової задачі, не розв'язаної відносно похідної, використано метод найменших квадратів. Як приклад застосування запропонованої ітераційної схеми знайдено наближення до розв'язків періодичних крайових задач, не розв'язаних відносно похідної, у випадку періодичної задачі для рівняння, яке моделює рух супутника на еліптичній орбіті. Знайдено оцінку проміжку значень малого параметра, для якого збіжність ітераційної процедури для побудови розв'язків слабконелінійної періодичної крайової задачі для рівняння типу Релея, не розв'язаного відносно похідної, є збіжною. Для перевірки точності знайдених наближень оцінено нев'язки у рівнянні, яке моделює рух супутника на еліптичній орбіті.
Dynamics of a random Hopfield neural lattice model with adaptive synapses and delayed Hebbian learning
Authors: Han Xiaoying , Kloeden Peter E. 
Published: January 2024

UDC 517.9
A Dong–Hopfield neural lattice model with random external forcing and delayed response to the evolution of interconnection weights is developed and studied. The interconnection weights evolve according to the Hebbian learning rule with a decay term and contribute to changes in the states after a short delay. The lattice system is first reformulated as a coupled functional-ordinary differential equation system on an appropriate product space. Then the solution of the system is shown to exist and be unique. Furthermore it is shown that the system of equations generates a continuous random dynamical system. Finally, the existence of random attractors for the random dynamical system generated by the Dong–Hopfield model is established.

Gnuastro: Measuring Radial Profiles from Images
Authors: Infante-Sainz Raúl , Akhlaghi Mohammad , Eskandarlou Sepideh 
Published: January 2024

Abstract
Radial profiles play a crucial role in the analysis and interpretation of astronomical data, facilitating the extraction of spatial information. However, highly customizable (for different scenarios) measurements over each elliptical annulus can be challenging. In response, we present astscript-radial-profile, which is part of Gnuastro from version 0.15 and has an extensive documentation. A convenient feature of this program is its capability to make the measurements with different operators (mean, median, sigma-clipping, and many more) over ellipses, very quickly and directly on the command-line with minimal dependencies. This research note is reproducible with Maneage, on the Git commit f3ec942.
Titan’s Atmospheric Albedo Asymmetry and Seasonal Variability Observed through the Cassini Imaging Science Subsystem
Authors: Snell C. , Banfield D. 
Published: January 2024

Abstract
Using images from Cassini, we analyzed the north–south albedo asymmetry that has been observed in the atmosphere of Saturn’s moon, Titan. Suitable images from the Cassini Imaging Science Subsystem taken at 889 nm spanned from 2004 to 2017—around half of a Titan year—and revealed seasonal changes in the characteristics and orientation of the north–south asymmetry boundary. Such circumglobal features provide insight into the dynamics and circulation of the atmosphere more broadly. The albedo asymmetry has been observed to reverse for part of the Titan year, inverting the brighter and darker hemispheres; we also observed this inversion, along with the formation of additional banding briefly during the transition (around 2014–2016). A tilt in the rotation axis of Titan’s atmosphere with respect to the solid body rotation has previously been noted. Using robust edge-detection techniques, we likewise identified a tilt offset of a few degrees in the albedo transition boundaries. The azimuth of this tilt axis remained roughly fixed in inertial space, with some smaller possible seasonal fluctuations around the fixed direction noted.
Branching Models in Practice: Tackling Real-Life Challenges Beyond Theoretical Constructs Using Python Programming
Authors: Adeyinka Abdulazeez Sikiru 
Published: January 2024

The mathematical modeling of branching processes finds its origin in attempts to model reproduction patterns in species. For systems with replicating and dying components (like cells or particles), branching process theory provides the mathematical tools for understanding their probabilistic progression.. They are used to describe random systems such as chain reactions, survival of family names, pest eradication, population development and gene propagation. This study showcases clear illustrations of the likelihood of extinction, the duration until extinction, and the probability related to the entire offspring. Observations of past elite families often highlight their eventual decrease, leading to myriad speculations. Through Python-based modeling, it was found that if every person, on average, yields slightly over one offspring, there is no absolute guarantee of family extinction. However, if the mean number of offspring per individual  is one or less, the process is guaranteed to become extinct.

Discontinuous Reception (DRX) Mechanism is the power saving technique employed by the Long Time Evolutional (LTE) Network to reduce the power saving. The scheme has seen numerous improvements and tuning to enhance its performance. The Machine Type Communication (MTC) devices have characters that widely differ from the normal devices (Human Type Devices). Therefore, DRX schemes needs to be adjusted to fully accommodate MTC. In this work, a survey of MTC DRX scheme literatures is adapted depicting challenges and potential.
Assessment of Numerical Performance of Some Runge-Kutta Methods and New Iteration Method on First Order Differential Problems
Authors: Audu Khadeejah James , Taiwo Aliyu Rasheed , Soliu Abdulganiyu Alabi 
Published: January 2024

This research focuses on the assessment of the numerical performance of some Runge-Kutta methods and New Iteration Method “NIM” for solving first-order differential problems. The assessment is conducted through extensive numerical experiments and comparative analyses. Accuracy, efficiency, and stability are among the key factors considered in evaluating the performance of the methods. A range of first-order differential problems with diverse characteristics and complexity levels is employed to thoroughly examine the methods' capabilities and limitations. The numerical investigation that is defined in the study as well as the results that are stated in the Tables, demonstrates that all the approaches produce extremely accurate results. However, the “NIM” was shown to be the most effective of the three methods used in this study. Conclusively, the “NIM” should be employed to solve first-order nonlinear and linear ordinary differential equations in place of Runge-Kutta Fourth order method (RK4M) and Butcher Runge-Kutta Fifth order method (BRK5M). In addition, BRK5M is more applicable and efficient than RK4M when solving first order ordinary differential problems.

Authors: Airen J.O. , Osifo J.O. 
Published: January 2024

An investigation of the groundwater potential of the area for tube well construction has been conducted in Layunrun village in a typical basement complex of Ogun State using electromagnetic and electrical resistivity techniques in geophysical exploration. Six (6) electromagnetic profiles were used, and twenty-eight (28) Vertical Electrical Soundings (VES) were performed along some of the profiles' potential regions. The typical partial curve matching utilized to create the VES curves was examined, and the results were used to create themed maps of the region. Within the study area, between four and six geoelectric layers were found. These layers are Topsoil, weathered layer (clay), weathered layer, fractured basement, and fresh basement. According to the findings, a bigger percentage of the land has an overburden thickness ranging from 9 to 17 m, with a maximum overburden of about 23 m. It also showed how well fractured the research area is, with thicknesses of the fractures varying from about 12 m to more than 30 m. The study area has a good chance of accumulating groundwater and, consequently, developing groundwater through digging boreholes. The outcomes also suggested that a community with similar geological settings may use the electromagnetic method in addition to the electrical resistivity method to identify places with high groundwater potentials.

The study examines the dynamics of population increase on urban governance in Nigeria with particular reference to Enugu State. The study specifically examine the effect of unemployment on urban governance in Enugu state and also ascertain the effect of increase in crime rate on urban governance in Enugu state. The theory used is push pull factor theory. Data for the study was sourced through the use of questionnaire, result of analysis showed that unemployment rate has negative effect on urban governance in Enugu state. It was also observed that over utilization of basic amenities adversely affects urban governance in Enugu state. Increases in crime rate has negative effect on urban governance in Enugu state. Based on the findings, the study recommended that Rural-Urban drift should be addressed more at the local level that is closer to the members of the countryside, by making them understand the environment as well as the economic implication of their migration to urban centres through various public enlightenment programs. The major factor that led to rural-urban drift to a great extent, government at the state level, supported by federal, should embark on various physical development and the provision of basic infrastructural facilities, services and social amenities in rural areas. This will reduce the level ofinequalities between the urban centres and rural areas. Thus, will naturally control the rural-urban drift. To ensure environmental sustainability in cities, planting of trees is imperative. Government should embark on massive tree planting and encourage citizensto plant trees by providing free seedlings for citizens.
