ON TOPOLOGY OF CENTROSYMMETRIC MATRICES WITH APPLICATIONS
Authors: Koyuncu S. , Ozel C. , Albaity M.
Published: November 2023

In this work, we investigate the algebraic and geometric properties of centrosymmetric matrices over the positive reals. We show that the set of centrosymmetric matrices, denoted as $\mathcal{C}_n$, forms a Lie algebra under the Hadamard product with the Lie bracket defined as $[A, B] = A \circ B - B \circ A$. Furthermore, we prove that the set $\mathcal{C}_n$ of centrosymmetric matrices over $\mathbb{R}^+$ is an open connected differentiable manifold with dimension $\lceil \frac{n^2}{2}\rceil$. This result is achieved by establishing a diffeomorphism between $\mathcal{C}_n$ and a Euclidean space $\mathbb{R}^{\lceil \frac{n^2}{2}\rceil}$, and by demonstrating that the set is both open and path-connected. This work provides insight into the algebraic and topological properties of centrosymmetric matrices, paving the way for potential applications in various mathematical and engineering fields.
ON THE SELECTION AND CHRONOLOGY OF ULYANIVKA TYPE KNIVES
Authors: Lytvynenko R. O.
Published: November 2023

In the collection of metal artifacts of the Late Bronze Age of the Northern Pontic region a series of bronze knives (7 objects) is distinguished, which are characterized by a notable morphological and technological feature: they have double-edged blade and a forged waist with thickening and )(-like layering of the metal at the point of transition of the blade to the handle. Among these finds, four items come from the barrow burials of Berezhnivka-Mayivka Zrubna Culture (BMZC): Basan’, Babakova Moghila 3/5 (kurgan/burial), Ivanivka 1/1, Mynkivka 6/1, Novomykolaivka, Smolovs’ka Mohyla 1/5. One knife was part of the Ulyanivka hoard of bronze objects, Mykolaiv region. Two more knives are the accidental finds from the Sumy region and Glukhiv of the same region.

All mentioned burials with knives according to their burial features and grave goods, as well as according to the data of stratigraphy, represent the late period of the BMZC. Researchers attribute the Ulyanivka treasure either to the early period of the Sabatynivka culture, or to the late stage of the Babyne culture. Contrary to this, it seems to be more reasonable that the Ulyanivka hoard belongs to the early Sabatynivka culture and probably may be synchronized with the late BMZC. This conclusion is confirmed by the materials of the Loboykivka hoard (Dnipropetrovsk region), which includes several knives with smoothed (leveled) traces of end forging. The Loboykivka hoard belongs to the BMZC and is traditionally synchronized with the Ulyanivka hoard.

The territorial distribution of knives with forged waist and )(-like layering of the metal shows that almost all of them within the Zrubna Culture (BMZC) area were found. This fact is decisive for the cultural attribution of such knives. Only the Ulyanivka hoard was found in the area of the Sabatynivka culture, which hints at its corresponding affiliation. However, the composition of the objects of the Ulyanivka hoard itself (sickles, adze and knife) mostly corresponds to the Zrubna culture.

The discussed evidence allows us to distinguish the knives with forged waist and )(-like layering of the metal into a separate classification taxon and we can name them the Ulyanivka type knives.
THE «HOUSEHOLD OF CERAMIST 2» COMPLEX ON THE TRIPOLIAN GIANT-SETTLEMENT TALIANKI
Authors: Korvin-Piotrovs’kyy O. H. , Ovchynnykov E. D. , Chernovol D. K. , Zhelaha D. I. , Radomskyi I. S.
Published: November 2023

The Tripolian archaeological expedition of the Institute of Archaeology of the National Academy of Sciences of Ukraine during 2018—2019, 2021—2022 explored a separate planographic unit of the settlement-giant Talianki which was named «Household of ceramist 2». The complex consists of five ground dwellings, one pottery kiln (G) and a place from a possible kiln, two large objects («pit-paddocks») and other objects of various purposes (small depressions, workplaces).

Dwellings 54—56 consisted of two parts — a smaller entrance and a large residential one. The interior of the residential part is standard; the entrance framed with decor. Building 53 is characterized by its larger dimensions with an additional third room. The southernmost building 57 was much smaller, interior details almost not survived. At the lower floor of the building floor greases or pavements (buildings 53, 57), and depressions are found.

The kiln «G» was located outside the residential area of the settlement near the northwestern part of pit 3. The kiln shape is close to rectangular with rounded corners. Kiln is two-chamber with vertically connected joints. The combustion chamber is separated from the burning compartment by a grid and coupled to warm air vents. This kiln is built of stones, clay and a significant number of pottery fragments. The geomagnetic anomaly corresponding to the characteristics of the kiln was located near the western side of pit 4. No visible remains of the kiln found at this location.

Large pits 3, 4 were located on the line of deepened

objects, which runs parallel to the line of ground buildings already outside the residential zone of the settlement. Each of the pits consisted of two depressions. Several stages of use recorded: selection of local clay for construction («toloka» / pit-paddock), use as dugout, repeated disposal of waste (debris of furnace vaults, defective products, ash and utility waste).

A large number of ceramic fragments, bone and stone tools, anthropomorphic and zoomorphic figurines, fragments of models of houses, sledges, etc. are found inside and around the sites. The mass finding of ceramic items in pit 4 deserves special attention. These are 494 whole and fragmented clay items. In addition to the impressive amount of these items in one object, special attention is drawn to unfinished or damaged figurines, as well as prepared individual parts of future products and flattened lumps of clay. Given the large amount of this kind of «production waste», this complex may be considered as a workshop for the production of clay-plastics, and perhaps as a place of study.

The discovered complex ought to be reconstructed as a place of residence for a large family group consisting of 4 small families, or a separate polygamous family. This social group specialized in the production of ceramic wares, serving a much larger social group.
THE HISTORY OF THE STUDY OF STEPPE ENEOLITHIC IN SOUTHERN UKRAINE (based on the materials of saving expeditions 1950s―1990s)
Authors: Tarasenko I. H.
Published: November 2023

The article is devoted to the activities of the saving expeditions of the Institute of Archaeology of the Academy of Sciences of the Ukrainian SSR between the Southern Bug and Molochna rivers, where in the the significant melioration facilities have been constructed. The expeditions have discovered important material from the Eneolithic era, which significantly expanded the source base for its study.

During the long period of 1950―1990s, 178 Eneolithic burial mounds, three settlements and several sites were discovered. In the mid-1950s and 1960s, in particular, on the basis of saving expeditions’ materials the attempts to find out the cultural and chronological affiliation of the steppe Eneolithic sites have been made (researches by O. F. Lagodovska, V. M. Danylenko, O. H. Shaposhnykova, D. Ya. Telegin, etc.). Since the 1970s the first cultural and chronological models appeared, which also involved the Eneolithic material from excavations of the saving expeditions (the works of D. Ya. Telegin, V. M. Danylenko, O. H. Shaposhnykova). The Eneolithic material of the late 1960s―1990s came from barrow burials which significantly expanded the possibilities of researchers constructing the cultural-chronological models. From the late 1970s to the 1990s, the main discussions related to the steppe Eneolithic were initiated in the archaeological scientific community, most of which are actual up today. The basis for this was, in particular, materials obtained by saving expeditions of the South of Ukraine.

Based on Yu. Ya. Rassamakin’s cultural and chronological model of the steppe Eneolithic we can state that the Eneolithic material, discovered by the saving expeditions, shows all cultural varieties of this era beginning from the early period to the late one. The Skelyanska culture is represented by only three burials of the Novodanylivka type, concentrated in the north of the steppe region. The next was the Stohivska culture, represented in the region by settlements/sites and burials. The number of Middle and Late Eneolithic sites indicates a more active settlement of the region at that time. These periods are represented by burials of the Kvityanska culture and the post-Stohivska group of sites; settlements and burials of the Lower Mykhailivka culture, burials of the Zhyotilovo-Vovchansk type. The material obtained by the saving expeditions also shows the syncretic characteristic in the Late Eneolithic burials.
PIDHIRTSI GROUP OF SITES OF THE KYIV DNIPRO REGION OF SCYTHIAN AGE
Authors: Rzhevuska S. S.
Published: November 2023

The paper reveals the issue of population switch in the Kyiv Dnipro region which occurred gradually from the end of the 7th to the 5th centuries BCE. It is related to the origin of the Pidhirtsi group of sites. In historiography since 1950—1960s two hypotheses on this topic have been developed: the integration version based on the diffusion of forest-steppe and Mylograd cultural elements and autochthonous one. Nowadays, after the discovery of new archaeological sites and revision of the chronology, the more progressive research direction is processual migration archeology. The design of the approach is multidisciplinary. The population switch phenomenon is connected to the climate caused migrations of the forest population of Mylograd culture to the Upper and Middle Dnipro regions. In such circumstances with a range of cross-cultural contacts, the Pidhirtsi group of sites was formed.

The settlement structure reconstructed on the basis of the material culture changes in correlation with geo informational analysis of the sites for two chronological periods. The impulses of the Mylograd population were caused by the economic crisis and paleoclimatic situation, in fact cooling and increasing humidity. The first diffusion occurred at the end of 7th century BCE and traced after burial complexes. The peak of population switch took place in the end of 6th — beginning 5th centuries BCE. As an example of material culture change were revised the materials of Bortnychi settlement explored in the 1950s. In the area of the Mylograd culture was observed decreasing of the anthropogenic activity. The forest steppe population inhabited the Left Bank Dnipro — Don region.

Reconstruction of the cultural and historical context on the forest and forest-steppe frontier is a necessary approach for understanding the regional settlement system. Long-range interdisciplinary paleoclimatic studies of the Kyiv Dnipro region are a prospective direction for future research.
RECONSTRUCTING THE CLOTHES OF BOSPORAN WOMAN.
Authors: Klochko L. S. , Vasina Z. O.
Published: November 2023

The study of clothes of people who lived in Ukrainian territories during Scythia times has large bibliography. The sources for reconstruction of different types of clothes, shoes, headwear and jewelry are archaeological art materials, most of which come from the burials. The burials located in Crimea provide a peculiar information regarding clothes of Bosporan Kingdom’s citizens. Near Tobechiv lake the kurgans which are called Three Brothers were excavated. One of them (N 1 Elder Brother) had the burial of the middle-aged woman with accompanying individual. The burial rite, the objects and mainly — the jewelry on the clothes, indicate the high status of this woman. While recreating her clothes, the central image on the burial stele which marks the burial 1 has high importance. We are talking about the image of the woman wearing the headwear — the kalafa — on top of the stlenhida with, probably, pendants. The buried woman had similar headwear. It is indicated by golden arc-shaped with relievo ornament. The main part depicts the fight between crouching panther (on the left) and lion (on the right). Above them is the ornament of palmette and lotus flower.

The thin golden plate is the applique which preserved the outline of the headwear of kalafa type — the crown which resembles the basked or cut cone, turned up with its wider side. The lover part of the plate, in the forehead part, has pendants with several particles: beads, plates with double spirals and bean-shaped pendants.

The woman had another headwear — forehead ribbon. It had small golden plates with the image of goddess Nika and palmettes. While women of Bosporus combined kalafa and stlenhida, Scythian women combined their headwears with forehead ribbons decorated with golden stripes or plates. The decoration of headwear had protective functions as well as religions sense — animal and plant images depict gods of nature.

The earrings were hanged to ribbons, as well as to stlenhidas. In this case it is the beautiful creations of Greek masters — sculptural creations depicting the sphinx. They created the composition along with the headwear decoration. The demonstration of earrings in this way fully represented their art and sense characteristics. The costume is also represented by the bracelets and rings. The rich costume, which decoration represents the symbols of gods of nature, might indicate the spiritual functions of the woman.
Selectivity control towards CO versus H2 for photo-driven CO2 reduction with a novel Co(II) catalyst
Authors: Gracia Lisa-Lou , Henkel Philip , Fuhr Olaf , Bizzarri Claudia
Published: November 2023

Developing efficient catalysts for reducing carbon dioxide, a highly stable combustion waste product, is a relevant task to lower the atmospheric concentration of this greenhouse gas by upcycling. Selectivity towards CO2-reduction products is highly desirable, although it can be challenging to achieve since the metal-hydrides formation is sometimes favored and leads to H2 evolution. In this work, we designed a cobalt-based catalyst, and we present herein its physicochemical properties. Moreover, we tailored a fully earth-abundant photocatalytic system to achieve specifically CO2 reduction, optimizing efficiency and selectivity. By changing the conditions, we enhanced the turnover number (TON) of CO production from only 0.5 to more than 60 and the selectivity from 6% to 97% after four hours of irradiation at 420 nm. Further efficiency enhancement was achieved by adding 1,1,1,3,3,3-hexafluoropropan-2-ol, producing CO with a TON up to 230, although at the expense of selectivity (54%).

Published: November 2023

Gas lift optimization is very challenging even in the mist of availability of gas assets as this involves modeling reservoirs accurately. Non availability of good software hinders best results such as obtaining critical gas lift design parameters like appropriate absolute open flow (AOF), skin factor, formation productivity index and the skin factor or even the reservoir pressure. The aim of this work is to design a model to gas lift an oil well in the Niger Delta for improved oil optimization. In other to achieve this aim the following objectives are considered; determine the maximum production rate achievable using gas lift, determine the optimum lift gas injection rate and depth and design the operating and unloading valves. Integrated Production Management (IPM) software was used with data from an oil well in the Niger Delta. Results show that the AOF gave 18026.3STB/day, formation PI gave 10.56STB/day/psi while the skin factor gave a positive value of 2. Pipe correlation used is Beggs and Brill. The maximum and minimum gases available are both 15mmscf/day. Water cut is 80%. The use of gas lift is very appropriate when the gas cap is a major source of reservoir energy
Two-headed parthenogenetic lizard embryo from southern Georgia

Published: November 2023

Abstract

Visual inspection of several embryos of the parthenogenetic lizard Darevskia armeniaca revealed the presence of an embryo with axial bifurcation (“two-headed”) on the stage of pigmented eyes and plate-like limb buds with a distinct border at the edges. This is the third recorded case of axial bifurcation in D. armeniaca, although two previous cases were mentioned without further discussion. Here the bicephalic embryo is described in detail and the potential reasons are discussed. The analysis of the literature on axial bifurcation in lacertids suggests that this type of developmental disorder may be particularly common in this parthenogenetic form. Hybridization may cause multiple developmental disorders, including incomplete separation of twin embryos; all parthenogenetic Darevskia have a hybrid origin, and this may cause the disorders rather than parthenogenetic reproduction by itself. The hypothesis needs further study with more representative samples of parthenogenetic and sexually reproducing Darevskia.
Creativity Without Agency: Evolutionary Flair & Aesthetic Engagement
Authors: Currie Adrian , Turner Derek
Published: November 2023

Common philosophical accounts of creativity align creative products and processes with a particular kind of agency: namely, that deserving of praise or blame. Considering evolutionary examples, we explore two ways of denying that creativity requires forms of agency. First, we argue that decoupling creativity from praiseworthiness comes at little cost: accepting that evolutionary processes are non-agential, they nonetheless exhibit many of the same characteristics and value associated with creativity. Second, we develop a ‘product-first’ account of creativity by which a process is creative just in case it gives rise to products deserving of certain forms of aesthetic engagement.
Medium Independence and the Failure of the Mechanistic Account of Computation
Authors: Maley Corey J.
Published: November 2023

Current orthodoxy takes representation to be essential to computation. However, a philosophical account of computation that does not appeal to representation would be useful, given the difficulties involved in successfully theorizing representation. Piccinini's recent mechanistic account of computation proposes to do just that: it couches computation in terms of what certain mechanisms do without requiring the manipulation or processing of representations whatsoever (Piccinini 2015). Most crucially, mechanisms must process medium-independent vehicles. There are two ways to understand what "medium-independence" means on this account; however, on either understanding, the account fails. Either too many things end up being counted as computational, or purportedly natural computations (e.g., neural computations) cannot be counted at all. In the end, illustrating this failure sheds some light on the way to revise the orthodoxy in the hope of a better account of computation.
Is Persuasion in the Eye of the Beholder?
Authors: Mendes Thomas Rui , Antunes Ana Cristina
Published: November 2023

Digital marketing is being revolutionized by technological advancements in many fields, such as artificial intelligence and persuasive technologies. Persuasive technology still generates disagreements, both on the marketer side, by setting up a persuasive system, and on the consumer side, who is responsible for accepting and instilling. This chapter presents a case study, which focuses on a Portuguese sports betting app – Placard. The aim is to examine Placard gamblers' behaviors, attitudes, and preferences, and how their user experience is influenced by the persuasive technologies embedded in this app. The main results allow a conclude that, no matter how much persuasive technology is programmed, and designed to change a certain behavior, it will always depend on the user, as well as on the different factors that influence their decision. The persuasive sports betting platform itself also needs to provide a better user experience to trigger less resistance. These results are discussed for the benefit of future digital marketing strategies and tactics withing online gambling.

Published: November 2023

This study explores the impact of foreign direct investment (FDI) on the economic growth of Somalia in between 1998-2019. To estimate the economic growth model, the study applied the autoregressive distributed lag (ARDL) method. Findings from the study showed that the major drivers of economic growth in the long run are inward FDI, labor stock, domestic investment, and exports. In the short run, the growth drivers are the labor force stock, domestic investment and current FDI stock. It was determined that inflation did not have a significant effect on economic growth in Somalia.
The Relationship Between Corporate Social Responsibility and Tax Avoidance
Authors: Baccouche Ahlem , Bouzgarrou Houssem , Jouirou Meriem , Ben Saada Moufida
Published: November 2023

This chapter highlights the impact of CSR on the tax avoidance of French firms, as well as the moderating role of directors with experience abroad on this relationship. On a sample of 55 listed French firms during the period 2007 to 2016, the authors perform the generalized least square method to correct the problems of heteroscedasticity and autocorrelation. They find that socially responsible firms refrain from making tax avoidance strategies, but argue that directors with foreign experience take advantage of the reputation of socially responsible firms as a hedge to help them optimize their tax avoidance strategy.
Hedging With Futures
Authors: Krishnan Deepika
Published: November 2023

This research explores the utilization of wavelet transform decomposition as an effective tool for hedging in the Indian stock market, particularly focusing on hedging with index futures contracts. Utilizing daily data obtained from the National Stock Exchange (NSE) of India spanning from 2010 to 2022, the study investigates the lead-lag relationships, correlations, and hedge ratios across different time scales through the wavelet transform method. The findings indicate a clear relationship between the Nifty 50, Nifty Bank, and Index futures in both short and longer time frames. However, in intermediate time scales, the Nifty Bank contract exhibits a leading position in the market. The correlation analysis underscores that time plays a crucial role in determining the variations, resulting in a wide range of correlations. The effectiveness of hedging, measured by the hedge ratio, displays an increasing trend across different time zones.

Cardiovascular diseases (CVD) rank among the leading global causes of mortality. Early detection and diagnosis are paramount in minimizing their impact. The application of ML and DL in classifying the occurrence of cardiovascular diseases holds significant potential for reducing diagnostic errors. This research endeavors to construct a model capable of accurately predicting cardiovascular diseases, thereby mitigating the fatality associated with CVD. In this paper, the authors introduce a novel approach that combines an artificial intelligence network (AIN)-based feature selection (FS) technique with cutting-edge DL and ML classifiers for the early detection of heart diseases based on patient medical histories. The proposed model is rigorously evaluated using two real-world datasets sourced from the University of California. The authors conduct extensive data preprocessing and analysis, and the findings from this study demonstrate that the proposed methodology surpasses the performance of existing state-of-the-art methods, achieving an exceptional accuracy rate of 99.99%.

A Comparative Study of Longitudinal Vehicle Control Systems in Vehicle-to-Infrastructure Connected Corridor
Authors: King Brian , Olson Jordan , Hamilton Kayla , Fitzpatrick Benjamin , Yoon Hwan-Sik , Puzinauskas Paul
Published: November 2023

Vehicle-to-infrastructure (V2I) connectivity technology presents the opportunity for vehicles to perform autonomous longitudinal control to navigate safely and efficiently through sequences of V2I-enabled intersections, known as connected corridors. Existing research has proposed several control systems to navigate these corridors while minimizing energy consumption and travel time. This article analyzes and compares the simulated performance of three different autonomous navigation systems in connected corridors: a V2I-informed constant acceleration kinematic controller (V2I-K), a V2I-informed model predictive controller (V2I-MPC), and a V2I-informed reinforcement learning (V2I-RL) agent. A rules-based controller that does not use V2I information is implemented to simulate a human driver and is used as a baseline. The performance metrics analyzed are net energy consumption, travel time, and root-mean-square (RMS) acceleration. Two connected corridor scenarios are created to evaluate these metrics, including one scenario reconstructed from real-world traffic signal data. A sensitivity analysis is also performed to quantitatively identify key parameters that have the highest impact on the three metrics of interest.
Pedestrian Intention Prediction and Style Recognition in Bird’s-Eye View
Authors: Li Wenli , Wang Mengxin , Gong Xiaohao , Tang Yuanhang
Published: November 2023

In this article, pedestrian crossing intention and pedestrian crossing style are studied by means of statistical theory and artificial neural network. Feature parameters such as the average speed of pedestrians, pedestrian attention to vehicles, and vehicle arrival speed are extracted before and during the time pedestrians cross the street from a bird’s-eye view. Based on these parameters, an artificial neural network is used to predict the pedestrian crossing intention. K-means statistical method was used to cluster the pedestrian crossing styles, and the results showed that clustering the crossing styles into three categories, conservative, cautious, and adventurous, has a better classification effect, and the crossing behaviors of different types of pedestrians were analyzed. A random forest-based model is used to identify pedestrian crossing styles, the prediction accuracy reaches 91.83% and the recognition accuracy reaches 93.3%. The research content of this article can provide the foundation for intelligent driving pedestrian prediction, pedestrian crossing scene simulation, and traffic management.
Low-Speed Continuous Slip SAE No. 2 μPVT Procedure
Authors:   Automatic Transmission and Transaxle Committee
Published: November 2023

This SAE Recommended Practice is intended as the definition of a standard test, which may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use.

The SAE No. 2 friction test is used to evaluate the friction characteristics of automatic transmission plate clutches with automotive transmission fluid combinations.

The specific purpose of this document is to define a µPVT test for the evaluation of the variation of wet friction system low speed slip characteristics as a function of speed, temperature, and pressure. This procedure is intended as a suggested method for both suppliers and end users.

The only variables selected by the supplier or user of the friction system are:

Friction material

Fluid

Reaction plates

Oil flow (optional)

These four variables must be clearly identified when reporting the results of this test. If any of the test parameters or system hardware as described in this document are changed—other than the friction material, test fluid, or reaction plates—the data may not be reported as being obtained using this document.

This procedure is intended to evaluate ramped speed friction characteristics, also called sweeps, and can be used to demonstrate capacity changes that occur between the different levels of slip speed, applied pressure, and fluid temperature. The level of coefficient of friction, as well as the trends in torque capacity with speed, can be used to compare candidate materials or fluids.
Kohelet’s Escape: The Heart Freely Subordinated to Divine Navigation
Authors: Grenier Marc
Published: November 2023

It is often claimed that Ecclesiastes constitutes an irremediable enigma which flies in the face of traditional Hebrew cosmology, making the author’s intended meaning not much more than a bewildering speculative task. Biblical scholars disagree on just about every aspect of this ancient Hebraic work: authorship, date, structure, narrative framework, and even its connection to a Creator God. This essay utilizes Ballantine’s strategic rhetorical perspective to introduce and wade through some of the central controversies and debates about the meaning of Ecclesiastes: Is earthly life meaningful or meaningless ? Is there eternal meaning to earthly life or not? Is the earthly life of human beings pointless and futile or not? If the simple pleasures of earthly life are gifts from God, then how can earthly life itself be ‘hevel’? and more. Somewhat surprisingly, it concludes that Ecclesiastes is anything but an enigma when viewed rhetorically, and certainly not in contravention of basic Hebraic and Christian biblical principles about the sovereign importance of believing in God and obeying the Commandments, even despite all the trials and tribulations offered by earthly life.

Diabetes is a type of metabolic disorder, which is the cause of many dangerous complications. Ensete glaucum (Musaceae family) has active ingredients with antioxidant and hypoglycemic characteristics in some parts of the plant. This study investigates the ability to reduce blood sugar based on the inhibition of α-amylase and α-glucosidase enzymes of Ensete glaucum stem extract. The results indicated that 70% ethanol, a material ratio of 1/30, and a temperature of 65oC for 360 minutes are the optimal conditions for the extraction process. Sonication has an extraction efficiency that is 1.8 times greater than that of a thermostatic bath or shaker. With the above conditions, the total polyphenol contents of the upper and the lower stem samples combined with sonication are higher than those without sonication. The ability to capture 2,2-Diphenyl-1-picrylhydrazyl (DPPH) free radicals of the extract used with sonication in the upper stem is four times higher than without sonication. In addition, the presence of sonication increases the capacity to inhibit the α-amylase enzyme (IC50 of the upper stem is 29.94 g/mL, the lower stem is 16.42 g/mL), compared to the absence of sonication (IC50 of the upper stem is 36 g/mL, the lower stem is 26.72 g/mL). Similar to the ability to inhibit α-glucosidase enzyme when using sonication (IC50 of the upper stem is 71.04 µg/mL, the lower stem is 91.91 µg/mL) is higher than not using sonication (IC50 of the upper stem is 142.99 µg/mL, the lower stem is 129.88 µg/mL). In general, the inhibition of α-amylase enzyme was higher than α–glucosidase enzyme in all extracts. In addition, the presence of sonication increased the polyphenol content, DPPH free radical scavenging, and hypoglycemic capacity of Ensete glaucum stem extract.
Data Mining technique: Application of Apriori algorithm for road accident analysis
Authors: Perez Ryan Clifford Larraquel
Published: November 2023

Road accidents can happen due to various factors. These factors that contribute to road accidents have cost damage to properties, injuries or deaths and most road accidents are attributable to the lack of knowledge on road safety. To provide safe driving and road safety plans, critical analysis of road accident data is needed, to identify the causes of road accidents. Annually, 1,250,000 people die and 50,000,000 are injured in road accidents worldwide, and fatal road accidents are caused by human error. Improving road conditions is not sufficient, but significantly understanding human errors that cause road accidents, and negligence of corrective and safety driving protocols provided by the concerned government agencies or private organizations. The study aimed to help get insights about the causes of road accidents, and to provide knowledge of road accidents for road safety using Association Rule Mining with the application of the Apriori Algorithm. Association rule mining using the Apriori Algorithm produces significant patterns and insights that help identify the causes of road accidents.

Big-eyed bugs Geocoris spp. are a natural enemy species presented in many parts of the world that have been extensively researched because of the benefits that they bring to plants. In Vietnam, big-eyed bugs are found in many places, especially in farming complexes or large farms. In Ho Chi Minh City, Geocoris sp. was found in Pham Van Coi Commune, Cu Chi District, Ho Chi Minh City, with bug density fluctuations across seasons at an average of 5.33 ± 2.67 individuals per point. The density of the big-eyed bug in Cu Chi District was 03 times higher than the density recorded in Ham Tan District, Binh Thuan Province. Morphological and molecular-based COI genes identified the speciments from Cu Chi, Ho Chi Minh City, and Ham Tan, Binh Thuan are Geocoris ochropterus. From the research results, these two sampling sites will be selected to further evaluate the rate of natural increase of the big-eyed bug Geocoris ochropterus.

Phytosome as a Novel Carrier for Delivery of Phytochemicals: A Comprehensive Review
Authors: Mehmood Humna
Published: November 2023

Phytomedicine is known for its excellent therapeutic applications owing to phytoconstituents present in plants, with no or least side effects. But its low bioavailability due large molecular size, poor lipid solubility and lack of stability of bioactive compounds make hindrance in its efficacy. Different strategies have been developed to generate the effective carrier systems to enhance bioavailability of phytochemica ls. One of the latest and most popular lipid-based carriers for delivering plants based pharmaceuticals and nutraceuticals is the phytosome. Phytosome is an emerging lipid based drug delivery approach which involves encapsulation of bioactive ingredient into phospholipid molecule mainly phosphatidylcholine. Phytosomes as phyto-phospholipid complexes lead to target drug delivery, better bioavailability and stability, enhanced pharmacological efficacy as well as the protection of bioactive compounds from chemical and physical degradation. Due to easy preparation of the bilayer vesicles and their effectiveness, phytosomes have been extensively employed and approved by the scientific literature. In this review, a phytosome technology, its structural components, formulation techniques, optimization, characterization approaches as well as merits and demerits are comprehensively discussed. Moreover, phytosome based market products and recent research is presented. It is concluded that phytosome technology is a gift for herbal extracts and phytochemicals that are inadequately bioavailable and have well-established processing methodologies as well as verified analytical techniques.
The Imperial Frontier in the Worldview of the Decembrists: F. N. Glinka—Romantic Christianity and Karelian Ethnography
Authors: Smirnov Vladimir N.
Published: November 2023

The article delves into reconstructing the religious-philosophical worldview of the Decembrist Fyodor Nikolaevich Glinka, set against the backdrop of his frontier experiences during his exile in the Olonets province. His poems, “The Maiden of the Karelian Forests” and “Karelia, or the Captivity of Marfa Ivanovna Romanova,” created during his residency in Petrozavodsk, are compelling blends of the era’s literary trends, Glinka’s personal religious beliefs, and ethnographic portrayals of Karelia. Consequently, the Karelian frontier is viewed through the diverse prism of F. N. Glinka, a Russian officer, Decembrist, poet, and religious thinker, who bequeathed an extensive literary oeuvre. This research is aimed to undertake an exhaustive analysis of F. N. Glinka’s literary contributions as a Decembrist and to historically and philosophically interpret his worldview, particularly focusing on frontier themes. The study meticulously perused Glinka’s artistic pieces, ethnographic entries, religious-philosophical writings, and his epistolary body of work. Insights were gleaned on the various dimensions of his perspectives and artistic endeavors. This article may captivate those researching the history of the Karelian frontier, the artistic and philosophical imprints of the Decembrists, and scholars intrigued by the nuances of Russian public discourse in the 19th century.
