Biosystematics of Sisymbrium irio Complex XIII : Taxonomic Considerations
Authors: Khoshoo T. N.
Published: May 2024

After a brief discussion on the biosystematic principles in relation to the traditional taxonomy, the variation pattern of the Sisymbrium irio complex has been considered taxonomically. From a utilitarian point of view, the complex is divisible into two (diploid-hexaploid; tetraploid-octoploid) species, although genetically there are four clear cut species. Such an arrangement is also in line with the genomic relations within the complex. For the present, it is proposed to treat the two members of each species as varieties. Only hexaploid matches with the Linnean holotype, and would thus get the name S. irio Linn. Pending a thorough search for synonymy within the species, a tentative scheme has been suggested.

Comparative physicochemical investigation of the inclusion compounds of cyclodextrins with arginine and histidine stereoisomers
Authors: Neacsu Andreea
Published: May 2024

The inclusion complexes of α-, β-cyclodextrin and 2-hydroxypropyl-α-cyclodextrin with two amino acid stereoisomers (L-, D-arginine and L-, D-histidine) were studied by using differential scanning calorimetry, thermogravimetry, Fourier transform infrared spectroscopy, and scanning electron microscopy methods. The solid inclusion compounds were prepared in a 1:1 molar ratio of the host and guest using the co-precipitation method. The pH measurements and structural visualization of complexes were carried out. The obtained results proved the formation of the complexes and revealed that the size and the symmetry of the cyclodextrin (CD) and also the structure and flexibility of the amino acid molecule had a significant influence on the complexation interaction. The correlation of the experimental data shows that βCD has a preference to form more stable complexes with levogir isomers of amino acid than αCD and 2-hydroxypropyl-α-cyclodextrin. The complexation of the amino acids isomers was accomplished by partial inclusion of the guest molecule in the CD cavity, and it was observed that CDs could better discriminate between histidine isomers than between arginine isomers.
Мultivariate analysis for rapid screening and prediction of solid-state compatibility in pharmaceutical preformulation studies-paving the road for machine learning
Authors: Cvetkovska Bogatinovska Elena , Geškovski Nikola , Petrushevski Gjorgji , Stefov Viktor
Published: May 2024

Multivariate analysis models were developed to evaluate the results obtained from a compatibility study designed for ibuprofen with a large group of different types of excipients, as a possible approach for rapid screening of the incompatibility between the active pharmaceutical ingredient (API) and excipients. The solid-state characterization of the binary mixtures was performed by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). Principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) using SIMCA® software were applied for evaluation of the experimentally obtained results. The optimal PCA model for the FTIR spectra explains 96.2 % of the variations in the dataset with good statistical indicators (R2X = 0.960, Q2 = 0.900), which was also the case for the PCA model for the DSC curves (R2X = 0.981, Q2 = 0.866). The applied PLS-DA models have shown similar behaviour to the PCA. Moreover, the main spectral variations in the FTIR spectra and the thermal events in the DSC data were attributed the highest variable importance for the projection (VIP) scores in the corresponding VIP plots, confirming the model capability for predicting ibuprofen interactions. Furthermore, the prediction power of the optimal models for FTIR and DSC experimental data was evaluated by the root mean square error of prediction (RMSEP) of 0.10 and 0.16, respectively. The obtained results demonstrated the potential of multivariate statistical analysis as a machine learning-based technique for screening and prediction of ibuprofen-excipients solid-state compatibility in the preformulation phase of the pharmaceutical development of dosage forms.

Published: May 2024

Hairy root (HR) cultures of Hypericum perforatum L. have shown promise in controlling hyperglycemia, regulating blood lipid and enzyme profiles, and improving metabolic function in vivo. These benefits are mainly attributed to the phenolic acids, flavonoids, and xanthones present in HR extracts. However, the specific mechanism underlying these effects remains unclear. This study was performed to elucidate the biochemical and molecular mechanisms driving HR the antihyperglycemic and antidiabetic effects of HR extracts.
HR extract (200 mg/kg body weight) was administered daily for 14 days to healthy rats and rats with streptozotocin-induced diabetes, with glibenclamide serving as a positive control. The phenolic composition of the HR extracts was confirmed through high-performance liquid chromatography/diode array detection/electrospray ionization mass spectrometry (HPLC/DAD/ESI-MSn ) analysis.
The results showed that HR extract treatment increased the plasma insulin level and pancreatic poly (adenosine diphosphate-ribose) polymerase (PARP) activity in diabetic rats, thus normalizing blood glucose levels. Additionally, it reduced the activity of gluconeogenic enzymes, increased the activity of glycolytic enzymes, and normalized the glycogen content in the liver. HR extract-treated rats also exhibited increased hepatic adenosine monophosphate-activated protein kinase (AMPK) mRNA expression and a decreased protein kinase Cε (PKCε) concentration.
In conclusion, HR extract demonstrated insulinotropic effects and effectively regulated hepatic carbohydrate metabolism in diabetic rats by modulating AMPK expression and the PKCε concentration. These findings suggest the potential use of HR extract as an herbal medicine for diabetes treatment and a source of antidiabetic drug development.
Crossroads of vibrational (infrared and Raman) spectroscopy and X-ray powder diffraction in identification and characterization of some minerals – advantages and limitations. A review
Authors: Makreski Petre , Pejov Ljupco , Jovanovski Gligor
Published: May 2024

Many analytical methods have been successfully employed for the study of minerals, in particular, vibrational infrared (FTIR) and Raman spectroscopies and X-ray powder diffraction (XRPD). The advantages of the vibrational spectroscopic techniques for identifying and characterizing minerals include: rapid and versatile use; qualitative and quantitative chemical signatures; distinctive chemical fingerprint of a material; indirect determination of the crystal features (polymorphism, isomorphism, coordination, degree of deformation of structural polyhedra); small sample quantity (area less than 1 μm2 for Raman); wide coverage of 4,000 – 50 cm−1 region in a single scan; in situ and direct measurements without sample preparation; nondestructive use; etc. On the other hand, XRPD is a destructive technique that, depending on the method used and the density of the material, requires from a few micrograms up to around 5 grams of sample quantity for analysis. In spite of that, it is a rapid and powerful technique used in mineral studies with relatively straightforward interpretation of the results. During the last decade, portable X-ray powder diffractometers for the nondestructive analysis of art and archeological materials have been developed along with the portable and hand-held vibrational spectroscopy instrument. Here, some advantages and limitations in the process of the complementary use of FTIR and Raman vibrational spectroscopy and XRPD for identification and characterization of minerals are outlined.
Event-Driven AI Workflows in Serverless Computing: Enabling Real-Time Data Processing and Decision-Making
Authors: Donati Ottavia , Macario Muziano , Karim Mohd Hassan
Published: May 2024

Real-time data processing and decision-making are increasingly crucial in various applications, driven by the continuous influx of data streams. Event-driven AI workflows within serverless computing environments offer a promising approach to handle these real-time demands efficiently. This paper presents a framework for simulating and analyzing the performance characteristics of such workflows. Our proposed approach utilizes simulated data with varying event rates and durations to investigate the impact on key performance metrics like latency, throughput, and resource utilization. This enables a comprehensive evaluation of the inherent trade-offs within event-driven AI systems. The key findings reveal a trade-off between latency and throughput. As the event rate increases, average processing latency generally increases while average throughput increases. Resource utilization remains relatively stable across different event rates in the simulated scenarios (e.g., 75.55\% at 2 events/second, 74.51\% at 10 events/second). This framework provides a valuable tool for understanding the performance characteristics of event-driven AI workflows and optimizing resource allocation strategies.
Invasive Buttonweed Cotula coronopifolia (Asteraceae) Is Halotolerant and Has High Potential for Dispersal by Endozoochory
Authors: Sánchez-García Raúl , Green Andy J. , Tomasson Lina , Hortas Francisco , Ortiz Maria A.
Published: May 2024

Buttonweed (Cotula coronopifolia) is native to South Africa but invasive in wetlands in Europe, North America, and Australasia, where it excludes native plants. Despite being dry-fruited, field studies suggest migratory waterbirds can disperse its seeds via gut passage (endozoochory), aiding its expansion. To explore the potential for endozoochory in different regions and habitats, we collected seeds from six populations in Spain, Sweden, and the UK. Germination was tested under different salinity levels (0, 5, 10, 15 g/L) and simulated gut passage treatments: scarification, acidification, or both. No germination occurred at 15 g/L. Higher salinity reduced and delayed germination, but full gut passage treatment increased germinability and accelerated germination. Scarification or acid treatment alone resulted in intermediate germination patterns. There were significant salinity x population and gut passage x population interactions on germinability. The acceleration effect of gut passage on germination was stronger at 5-10 g/L than at 0 g/L. This study highlights how migratory birds can facilitate the spread of alien plants introduced by humans. Non-classical endozoochory by waterbirds is an understudied mechanism for the long-distance dispersal of dry-fruited alien plants. Further research on C. coronopifolia, including population genetics, is necessary to understand dispersal mechanisms and facilitate management strategies.

Published: May 2024

Background:
There have been reports of numerous risk factors for Alzheimer's disease. Although widely investigated, some points during the evolution of the disease have been obscure. One of them is a great frustration with therapeutic expectations. Why has there been an increase in suicidal behavior in treatments with anti-beta-amyloid drugs? Interpersonal stress is one of the factors that may be connecting Alzheimer's disease to suicide.
Method:
To observe possible associations between Alzheimer's disease and suicide, two validated questionnaires were selected. We recruited 20 elderly patients over 65 years old to observe the feasibility of further research using these instruments. The study was considered viable if all participants showed no difficulty in understanding the questions and completed both questionnaires in less than 30 minutes with a tendency to homogeneity. A description of the statistical data obtained was made.
Results:
All participants adequately understood the questions and completed the questionnaires in less than 30 minutes. In 10% of the sample, suicide attempts occurred throughout their lives. The average age of respondents was 75 years old. The QoSL Pareto diagram demonstrated a large concentration. The data demonstrated homogeneity.

Conclusions:
The application of the questionnaires in a sample suitable for carrying out analytical statistics was demonstrated. We have two great tools to try to understand the possible association between Alzheimer's disease and suicide.

Published: May 2024

The objective of this study is to investigate the correlation between the advancement of flood research and the utilization of Geographic Information Systems (GIS) and multi-criteria evaluation techniques, both from a theoretical and practical standpoint. Additionally, this research seeks to identify potential ways to address the aforementioned relationship. The present study employs a thorough literature review methodology. In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology, a total of 28 papers were identified and included in the analysis, as they fulfilled the predetermined criteria. The findings of the study indicate that current research pertaining to the utilization of Geographic Information Systems (GIS) and multicriteria evaluation in flood control mostly centers around five key areas, namely natural factors, technical considerations, institutional factors, socio-economic factors, and financial factors. However, the aforementioned studies have identified specific areas of focus, including natural factors pertaining to climate, technical factors related to infrastructure, institutional factors concerning flood management strategies, socio-economic factors associated with demographics, and financial factors pertaining to financial obligations. However, there is a limited amount of existing research that specifically addresses flood management in developing nations. Therefore, it is anticipated that this study can serve as a valuable resource for future research endeavors, particularly in informing decision-making processes pertaining to the establishment of priorities in flood control plans. The primary subject of this study pertains to flood management occurrences within developing nations.

Authors: Kim Soo-Dam , Pyo Sook-Jin , Kim Dong-Hyun , Yoo Hwa-Seung , Park So-Jung
Published: May 2024

Background: Gastric cancer (GC) is the second most prevalent cancer in Korea, significantly impacting morbidity and mortality. While advancements in early detection and treatment have improved survival rates, managing post-surgical recovery remains vital. Herbal medicine (HM) has emerged as a potential adjunct therapy to enhance recovery and quality of life (QoL) in patients post-GC surgery. Methods: This systematic review and meta-analysis evaluated the efficacy and safety of HM in the post-surgical recovery of GC patients. We searched both Korean and international databases, identifying 16 randomized controlled trials (RCTs) meeting our criteria. We assessed study quality using the Cochrane Risk of Bias tool and analyzed data with Review Manager Software (RevMan). Results: Our analysis included 1,546 patients from the selected studies, demonstrating that HM significantly improved gastrointestinal recovery times, including time to first flatus, bowel movement, and return of bowel sounds. Significant improvements were also seen in nutritional markers such as albumin and prealbumin, alongside beneficial effects on immune markers like CD3+ and CD4+ levels. QoL assessments using WHOQOL-BREF and QLQ-C30 scores indicated substantial improvements. HM had a favorable safety profile, showing a reduced incidence of adverse effects compared to controls. Conclusion: The findings suggest that HM can significantly enhance recovery and improve the quality of life following gastric cancer surgery, with a favorable safety profile. However, due to considerable heterogeneity in study results, extended clinical trials and rigorous follow-ups are recommended to assess long-term effects and side effects comprehensively.
The Queen Is Dead, Long Live the Queen: The Vanishing of Pinna nobilis and the Onset of the Congeneric P. rudis (Mollusca: Bivalvia)
Authors: Rubino Fernando , Fanelli Giovanni , Denti Giuseppe
Published: May 2024

The bivalve mollusc Pinna nobilis, endemic to the Mediterranean Sea, since 2016 is vanishing from the whole basin because of an infection by multiple pathogens that caused mass mortality events. In the Eastern Mediterranean some little populations seem to be resistant to the infection. These individuals could represent the only possibility for the species to recolonize now desert habitats. Thus, according to the recommendations of IUCN, the looking for living specimens of P. nobilis is a priority. As a result of a monitoring activity carried out in 2022-2024, along the Ionian cost of Apulia, in Southern Italy, the species has completely disappeared leaving only empty shells. Concurrent to the vanishing of P. nobilis, its congeneric P. rudis, resistant to the infection, seems to be taking advantage, becoming more common and colonizing habitats once exclusive of P. nobilis. In fact, from different areas of the Mediterranean, the sightings of P. rudis are increasing, together with the discovering of individuals exhibiting morphological traits that are a mixing between the two species. In some cases, these morphological features are not easy to detect, anyway the presence of these hybrids, resistant to the infection, is important for the conservation of the species.

Published: May 2024

Представлены результаты численных экспериментов по расчетам пространственного распределения электронной концентрации и потенциала электрического поля, формирующихся в результате градиентно-дрейфовой неустойчивости в области развитых экваториальных плазменных пузырей. Особенностью экваториальных плазменных пузырей является наличие больших отношений электронной концентрации вне плазменных пузырей к ее значениям внутри плазменных пузырей. Этим создаются большие градиенты концентрации и большие скорости поперечного к силовым линиям магнитного поля Земли дрейфового переноса. Такие условия возникновения больших положительных значений инкремента градиентно-дрейфовой неустойчивости, что приводит к усилению мелкомасштабных неоднородностей ионосферной плазмы с пространственно-временными масштабами, характерными для экваториального F-рассеяния. Полученные результаты согласуются с предыдущими работами авторов, направленными на исследование особенностей инкремента градиентно-дрейфовой неустойчивости. В отличие от предыдущих работ авторов, исследование в данной работе выполнено на основе прямого численного моделирования процесса развития неоднородности заданной в виде пространственно-ограниченной волны. Модель описывает процессы развития и усиления начальных неоднородностей с характерными размерами от нескольких десятков метров. Таким образом, градиентно-дрейфовая неустойчивость может являться причиной генерации мелкомасштабной структуры на фронтах плазменных пузырей в вечернее и ночное. В работах других авторов исследование проведено вне области ионосферных плазменных пузырей.

Published: May 2024

Наличие остатков атмосферы на сверхнизких орбитах $H = 100$---$200$ км, где должен
функционировать космический аппарат с прямоточным воздушным электрореактивным двигателем (КА с ПВЭРД) обуславливает необходимость выполнения газодинамических расчeтов для более точного моделирования динамики его движения по орбите. В соответствии с исследуемыми процессами такие расчeты могут быть разделены на 2 типа: обтекание внешних обводов КА потоком разреженного газа и его течение во внутреннем канале ПВЭРД. В первом случае оцениваются моменты и силы,
действующие на КА при движении по орбите, исследуются пути снижения аэродинамического сопротивления, рассматриваются варианты управления движением КА отклонением управляющих поверхностей. Во втором случае изучается течение газа
внутри входного устройства и накопителя, рассчитываются основные параметры
(давление, скорость и концентрация частиц вдоль продольного внутреннего канала),
анализируется их влияние на работу двигателя. Оба типа расчeтов позволяют оценить
возможность функционирования КА с ПВЭРД на низких орбитах, их результаты являются выходными данными для теоретического анализа динамики движения КА по
орбите. В данной работе рассматривается параметрически определяемая геометрия
КА с ПВЭРД в виде проточного канала (состоящего из конфузорной и цилиндрических частей с сотовым заполнителем на входе) с прикрепленными к нему плоскими
солнечными панелями. Основной результат исследования - оценка характеристик выбранной аэродинамической компоновки КА, частью которой является пассивный воздухозаборник двигательной установки. Оценен вклад с точки зрения аэродинамики
отдельных частей КА. Расчeты выполнялись с помощью метода прямого численного
моделирования Монте-Карло (DSMC), численная модель верифицирована с помощью
аналитических соотношений для простых форм.
Динамическая модель образования и разрушения агрегатов для описания эффекта изотермического пересыщения в ионите
Authors: Kaznacheev Mikhail Aleksandrovich , Tikhonov Nikolay Andreevich
Published: May 2024

Предложена динамическая модель образования и разрушения частиц пересыщенной фазы в межзерновом пространстве ионита для количественного описания эффекта изотермического пересыщения. Модель базируется на идее о существовании конкуренции между процессами объединения частиц пересыщенной фазы и их разрушения под действием поля зарядов функциональных центров ионита вблизи его поверхности. В результате этой конкуренции может быть достигнуто устойчивое состояние пересыщенного раствора. Проверено, что модель описывает экспериментальные данные по измерению степени пересыщения в зависимости от времени для растворов с одинаковым компонентным составом для двух различных ионитов.
Об одной граничной модели в задачах обтекания твердых тел газовым потоком
Authors: Polyakov Sergey Vladimirovich , Podryga Viktoriya Olegovna
Published: May 2024

Настоящая работа посвящена развитию многомасштабного подхода к расчету течений газа вблизи твердых поверхностей с учетом микроскопических эффектов. В рамках этого направления исследований рассматривается проблема постановки граничных условий на поверхности твердого тела с учетом данных эффектов, предварительно рассчитанных на атомно-молекулярном уровне. Основная цель работы состоит в формулировке макроскопических граничных уравнений, учитывающих процессы на поверхности обтекаемого газом твердого тела. В качестве основы макроскопической модели используется система квазигазодинамических (КГД) уравнений в объеме и уравнение теплопроводности в приповерхностном слое обтекаемого тела. Система дополняется реальными уравнениями состояния газа и зависимостями кинетических коэффициентов КГД уравнений от температуры и давления, полученными на основе молекулярно-динамических расчетов. Для апробации предложенных граничных уравнений рассмотрена задача об обтекании затупленного тела потоком газа. В качестве газа выбран сухой воздух. В качестве покрытия тела выбран никель. Расчеты проводились для двух значений скорости входного потока. Они подтвердили качественную корректность разработанной граничной модели и всей технологии моделирования.
Revisitando o programa dos CIEP, após 38 anos: debates na câmara municipal de Nova Iguaçu (RJ) sobre sua construção e financiamento

Published: May 2024

O presente artigo aborda a chegada dos Centros Integrados de Educação Pública (CIEP) a Nova Iguaçu-RJ, buscando problematizar os aspectos pedagógicos de tal política educacional na sociedade local. Partindo do recorte temporal dessa política (1983 a 1995) utilizamos, metodologicamente, análise documental de fontes como as atas da Câmara Municipal; reportagens divulgadas em jornais e entrevistas com profissionais de CIEP e moradores do município. Utilizamos ainda referencial teórico pautado no conceitos de campo (Bourdieu), e de cidadania (Demo) e da História local (Cavalcanti), o que possibilitou perceber a recorrência de debates acerca do aspecto pedagógico dos CIEP nas fontes, tendo como resultado a evidência de um processo de constituição de concepção pedagógica elaborada pelos “apossados” do campo político – idealizadores e vereadores –, mas sob a influência dos “profanos” – o público-alvo da política.

Published: May 2024

Despite the medicinal significance of traditional Thai herbs, their accurate identification on digital platforms is a challenge due to the vast diversity among species and the limited scope of existing digital databases. In response, this paper introduces the Thai traditional herb classifier that uniquely combines transfer learning, innovative data augmentation strategies, and the inclusion of noisy data to tackle this issue. Our novel contributions encompass the creation of a curated dataset spanning 20 distinct Thai herb categories, a robust deep learning architecture that intricately combines transfer learning with tailored data augmentation techniques, and the development of an Android application tailored for real-world herb recognition scenarios. Preliminary results of our method indicate its potential to revolutionize the way Thai herbs are digitally identified, holding promise for advancements in natural medicine and computer-assisted herb recognition.
FFD-SLAM: A Real-Time Visual SLAM Toward Dynamic Scenes with Semantic and Optical Flow Information
Authors: Zhang Hao , Wang Yu , Zhong Tianjie , Dong Fangyan , Chen Kewei
Published: May 2024

To solve the problem of poor localization accuracy and robustness of visual simultaneous localization and mapping (SLAM) systems in highly dynamic environments, this paper proposes a dynamic visual SLAM algorithm called FFD-SLAM that fuses the target detection network with the optical flow method. The algorithm considers ORB-SLAM2 as the basic framework, joins the semantic thread in parallel with its tracking thread, initially obtains the set of feature points through the real-time detection of dynamic objects in the environment through YOLOv5 in the semantic thread, then filters the set of feature points obtained in the semantic thread through the optical flow module, and finally utilizes the remaining static feature points for the matching calculation. Experiments showed that the proposed algorithm showed an improvement of approximately 97% in the localization accuracy compared with the ORB-SLAM2 algorithm in a highly dynamic environment, which effectively improves the localization accuracy and robustness of the system. The proposed algorithm also showed a higher real-time performance compared with some excellent dynamic SLAM algorithms.

This research aims to analyze the influence of product quality, product features, product style and design, brand image, and brand experience on consumer loyalty in the online gaming industry in the Depok, Bogor, Jakarta, Tangerang, Bekasi (Jabodetabek) area, with consumer satisfaction as an intervention variable. The results of data analysis show that online game product quality does not have a significant influence on consumer satisfaction, and the same thing applies to the direct influence of product quality on consumer loyalty. Online game product features also do not have a direct influence on consumer satisfaction and loyalty. Product style and design do not directly influence consumer satisfaction and loyalty in online games. However, brand image has a direct influence on consumer satisfaction, while brand experience has a direct influence on satisfaction. Consumer satisfaction, in turn, has a positive impact on consumer loyalty. Some factors, such as product quality, product features, and product style and design, may have an indirect influence on loyalty through satisfaction. Therefore, this research provides valuable insights for companies in developing marketing strategies and increasing consumer loyalty in the online gaming industry in the Depok, Bogor Jakarta, Tangerang, Bekasi (Jabodetabek) area.

Authors: Manickam Hemleen Soosai , Idris Sidah , Nipo Debbra Toria
Published: May 2024

In accordance with the ASEAN IPR Action Plan 2016-2025, this study explores the connections and causality of Intellectual Property Rights (IPR) on international trade (IT) of ASEAN+5 countries represented by Malaysia, Thailand, the Philippines, Singapore, and Indonesia. According to this, international trade is measured in terms of trade (as a percentage of GDP). IPR is measured by patent applications filed by residents, patent applications filed by non-residents, industrial design applications filed by residents, and industrial design applications filed by non-residents. Along with IPR, the effect of government effectiveness (GE) on IT is also investigated. Foreign direct investment (FDI) and inflation are also utilized as control variables. This study adopts new growth theory as to further explain the variables involved. All ASEAN+5 data for the individual variables were derived from the World Bank Development database, and the panel dataset was investigated using the PFGLS estimator and Dumitrescu-Hurlin test for over 21-years period (2000-2020). The findings of this study revealed a strong effect between IPR and IT as well as a unidirectional relationship between IPR (except industrial design application, filed by residents) and IT for the ASEAN+5 region. The limitation of this study is that it only focused on five ASEAN countries, and the selection of IPR indicators was limited. Nevertheless, this study provides some important insights for policymakers and local merchants to focus and invest more on IPR in order to promote ASEAN's international trade in accordance with global norms.
