Fast-tracking method of inertial constant based on system identification
Authors: Hu Xuekai , Zeng Siming , Meng Liang , Li Tiecheng , Zhang Qian
Published: January 2024

Aiming at the problem of quantitative inertia evaluation of a new energy electric power system, the system inertia constant tracking method based on system identification is studied. The method is divided into two categories: non-recursive algorithm and recursive algorithm. The non-recursive algorithm uses a batch of data for batch processing to obtain the estimated value of the identification model parameters. The recursive algorithm is based on the estimated value of the model parameter at the previous moment and corrects the estimated value based on the new data currently obtained. From the perspective of the identification principle, the difference and internal relationship between the two in terms of calculation storage and identification speed are analyzed. The IEEE typical system is used to compare and verify the experimental examples. Theoretical analysis and experimental results show that the recursive algorithm has high identification accuracy, stable identification results and fast identification speed. It is suitable for the identification of objects with large numbers of nodes and complex structures, which is conducive to real-time monitoring and fast perception of the inertia constant of the new energy power system.

Objetivo: Investigar a atividade da melatonina, como possível ferramenta no tratamento e reversão de danos causados ​​ao tecido testicular. Revisão bibliográfica: A nutrição adequada no período crítico do desenvolvimento, a fase de lactação, tem um impacto profundo na maturação das estruturas e funções reprodutivas dos mamíferos. Já é descrito na literatura as complicações no desenvolvimento da criança que foram submetidas ao desmame precoce, este que induz um desequilíbrio nutricional na prole, desencadeando um quadro de estresse metabólico. Dentre todos os sistemas afetados, o sistema reprodutor pode ser acometido de forma aguda e crônica, levando inclusive a problemas na fertilidade. Nesse contexto, a melatonina, entra como um adjuvante da terapia nutricional no tratamento e reversão das complicações decorrentes da desnutrição. Isso é ocasionado devido às suas propriedades antioxidantes e de preservação da estrutura celular, da ação dos radicais livres produzidos a partir do estresse metabólico. Considerações finais: A melatonina por suas propriedades antioxidantes e de proteção celular, pode ser uma alternativa como tratamento para os danos causados pelo desmame precoce. Muito embora a literatura careça de trabalhos que comprovem essa hipótese.
Les systèmes de certification du cacao améliorent-ils les performances des producteurs ? Expérience de la région du Centre au Cameroun
Authors: Sadeu Michael Brice Talla , Mathe Syndhia , Nzie Jules René Minkoua
Published: January 2024

In agricultural value chains, in particular cocoa, environmental, and social standards are becoming increasingly important in meeting sustainability challenges. The main aim of this article is to examine the role of certification primarily on the yields and incomes of cocoa farmers in the Central Cameroon region. From June to July 2017, a survey of certified and non-certified cocoa producers was conducted in the districts of Ngoumou and Mbangassina. At the end of the survey, a total sample of 114 certified and non-certified producers was obtained. Using the cost-benefit analysis, in this preliminary phase of the certification process, the results show that there is no significant difference in costs between certified and non-certified producers for each of the districts. There is also no price difference between certified and non-certified cocoa and the payment of the certification premium is not systematically distributed. However, the profit analysis shows on average significantly higher yields and profits for certified producers. Nevertheless, this increase in profits would mainly be due to the implementation of good agricultural practices rather than the certification itself. Additionally, the exploration of on farm income shows that cocoa-based households remain on average below the poverty line. One of the long-term challenges for the cocoa sector in Cameroon is to combine the government's objective of increasing production with that of improving quality. To this end, the advantages of the predominantly agroforestry systems present in Cameroon should be exploited to produce a critical mass of quality and sustainable cocoa that would allow a significant increase in producer prices.
Stress-Induced Alcohol Consumption in Young Adults
Authors:   Department of Clinical and Biological Psychology, University of Trier, Germany, R Laessle
Published: January 2024

Alcohol misuse and alcohol dependency are frequent in young adults in Germany. The cases have more increased in females than in males. Hypothesized is an association between stress load, stress coping and alcohol consumption for stress relief. A controlled laboratory experiment measured stress-induced beer consumption in 105 young women and men. Usual drinking behavior and stress coping were taken into account. After stress (TSST) beer intake was higher compared to control condition for men as well as for women. Stress coping was more inadequate in women. Alcohol consumption in laboratory is integrated in models of negative reinforcement and proposals of social cognitive learning theory.
In situ polymer gelation in confined flow controls intermittent dynamics
Authors: Smith Barrett , Hashmi Sara
Published: January 2024

Polymer flows through pores, nozzles and other small channels govern engineered and naturally occurring dynamics in many processes, from 3D printing to oil recovery in the earth’s subsurface to a wide variety of biological flows. The crosslinking of polymers can change their material properties dramatically, and it is advantageous to know a priori whether or not crosslinking polymers will lead to clogged channels or cessation of flow. In this study, we investigate the flow of a common biopolymer, alginate, while it undergoes crosslinking by the addition of a crosslinker, calcium, driven through a microfluidic channel at constant flow rate. We map the boundaries defining complete clogging and flow as a function of flow rate, polymer concentration, and crosslinker concentration. Interestingly, the boundaries of the dynamic behavior qualitatively match the thermodynamic jamming phase diagram of attractive colloidal particles. That is, polymer clogging occurs in a region analogous to colloids in a jammed state, while the polymer flows in regions corresponding to colloids in a liquid phase. However, between the dynamic regimes of complete clogging and unrestricted flow, we observe a remarkable phenomenon in which the crosslinked polymer intermittently clogs the channel. This pattern of deposition and removal of a crosslinked gel is simultaneously highly reproducible, long-lasting, and controllable by system parameters. Higher concentrations of polymer and cross-linker result in more frequent ablation, while gels formed at lower component concentrations ablate less frequently. Upon ablation, the eluted gel maintains its shape, resulting in micro-rods several hundred microns long. Our results suggest both rich dynamics of intermittent flows in crosslinking polymers and the ability to control them.
Apples to Apples: Shift from Mass Ratio to Additive Molecules per Electrode Area to Optimize Li-Ion Batteries

Published: January 2024

Electrolyte additives in liquid electrolyte batteries can trigger the formation of a protective interphase (SEI) atthe electrodes that aims to suppress side reactions at the electrodes. Studies of varying amounts of additives have been done over the last years, providing a comprehensive understanding of the impact of the electrolyte formulation on the lifetime of the cells. However, these studies mostly focus on the variation of the mass fraction of additive in the electrolyte while disregarding the ratio (radd) of the additive's amount of substance (nadd) to the electrode area (Aelectrode). Herein we utilize our extremely accurate automatic battery assembly system (AUTOBASS) to vary electrode area and amount of substance of the additive. The data provides strong evidence that reporting the mass ratios of electrolyte components is insufficient and the mol of additive relative to the electrodes’ area should be reported. Herein, the two most utilized additives, namely fluoroethylene carbonate (FEC) and vinylene carbonate (VC) were studied. Each additive was varied from 0.1 wt.-% - 3.0 wt.-% for VC, and 5 wt.-% - 15 wt.-% for FEC for two mass loadings of 1 mAh/cm2 and 3 mAh/cm2. To engage the community to find better descriptors, such as the proposed radd, we publish the dataset alongside this manuscript.
Simulated conformality of atomic layer deposition in lateral channels: the impact of the Knudsen number on the saturation profile characteristics

Published: January 2024

Atomic layer deposition (ALD) is exceptionally suitable for coating complex three-dimensional structures with conformal thin films. Studies of ALD conformality in high-aspect-ratio (HAR) features typically assume free molecular flow conditions with Knudsen diffusion. However, the free molecular flow assumption might not be valid for real ALD processes. This work maps the evolution of the saturation profile characteristics in lateral high-aspect-ratio (LHAR) channels through simulations using a diffusion-reaction model for various diffusion regimes with a wide range of Knudsen numbers (10^6 to 10^{-6}), from free molecular flow (Knudsen diffusion) through the transition regime to continuum flow conditions (molecular diffusion). Simulations are run for ALD reactant partial pressures spanning several orders of magnitude with the exposure time kept constant (by varying the total exposure) and with the total exposure kept constant (by varying the exposure time). In a free molecular flow, for a constant total exposure, the saturation profile characteristics are identical regardless of the LHAR channel height and the partial pressure of the reactant. Under transition regime and continuum conditions, the penetration depth decreases and the steepness of the adsorption front increases with decreasing Knudsen number. The effect of varying individual parameters on the saturation profile characteristics in some cases depends on the diffusion regime. An empirical method is proposed to relate the sticking coefficient to the saturation profile's characteristic slope for any Knudsen number.

Crystal polymorphism is an important and fascinating aspect of solid state chemistry with far reaching implications in the pharmaceuticals, agrisciences, nutraceuticals, battery and aviation industries. Late appearing more stable polymorphs have caused numerous issues in the pharmaceutical industry. Experimental polymorph screening can be very expensive and time consuming, and sometimes may miss important low energy polymorphs due to its inability to exhaust all crystallization conditions. In this paper, we report a crystal structure prediction (CSP) method with unprecedented accuracy and efficiency, validated on a large and diverse dataset including 65 molecules with 135 experimentally found polymorphic forms. The method combines a novel systematic crystal packing search algorithm and the first use of machine learning force fields in a hierarchical crystal energy ranking. Our method not only reproduces all the experimentally known polymorphs, but also suggests new low energy polymorphs yet to be discovered by experiment that might pose potential risks to development of the currently known forms of these compounds. In addition, we also demonstrate, in two prospective drug development projects, how the method was used to accelerate clinical formulation design and derisk downstream processing. The high accuracy, reliability, and efficiency of our method with large scale validations and prospective studies position it for routine molecular crystal structure prediction in drug development.
ATR–SEIRAS Method to Measure Interfacial pH during Electrocatalytic Nitrate Reduction on Cu
Authors: Corson Elizabeth R. , Guo Jinyu , Tarpeh William A.
Published: January 2024

This study reports the accuracy and applications of an attenuated total reflectance–surface-enhanced infrared absorption spectroscopy (ATR–SEIRAS) technique to indirectly measure the interfacial pH of the electrolyte using the ratio of phosphate species within 10 nm of the electrocatalyst surface. This technique can be used in situ to study aqueous electrochemical reactions with a calibration range from pH 1–13, time resolution down to 4 s, and an average 95% confidence interval of 14% that varies depending on the pH region (acidic, neutral, or basic). The method is applied in this study to electrochemical nitrate reduction at a copper cathode to demonstrate its capabilities, but is broadly applicable to any aqueous electrochemical reaction (such as hydrogen evolution, carbon dioxide reduction, or oxygen evolution) and the electrocatalyst may be any SEIRAS-active thin film (e.g., silver, gold, or copper). The time-resolved results show a dramatic increase in the interfacial pH from pH 2–7 in the first minute of operation during both constant current and pulsed current experiments where the bulk pH is unchanged. Attempts to control the pH polarization at the surface by altering the electrochemical operating conditions—lowering the current or increasing the pulse frequency—showed no significant change, demonstrating the challenge of controlling the interfacial pH.
Understanding Electrolyte Ion Size Effects on the Performance of Conducting MOF Supercapacitors

Published: January 2024

Layered metal-organic frameworks (MOFs) have emerged as promising materials for next-generation supercapacitors. Understanding how and why electrolyte ion size impacts electrochemical performance is crucial for developing improved MOF-based devices. To address this, we investigate the energy storage performance of Cu3(HHTP)2 (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene) with a series of 1 M tetraalkylammonium tetrafluoroborate (TAABF4) electrolytes with different cation sizes. Three-electrode experiments show that Cu3(HHTP)2 exhibits higher energy storage upon positive charging and an asymmetric charging response with all ion sizes, with a greater charging asymmetry with larger TAA+ cations. The results further show that smaller TAA+ cations demonstrate superior capacitive performance upon both positive and negative charging compared to larger TAA+ cations. To gain further insights, electrochemical quartz crystal microbalance (EQCM) measurements were performed to probe the ion electrosorption during charging. These reveal that Cu3(HHTP)2 has a cation-dominated charging mechanism, but interestingly indicate that the solvent also participates in the charging mechanism with larger cations. Overall, the results of this study suggest that larger TAA+ cations saturate the pores of the Cu3(HHTP)2-based electrodes, leading to more asymmetric charging and forcing solvent molecules to play a role in the charge storage mechanism. These findings significantly enhance our understanding of ion electrosorption in layered MOFs, and will guide the design of improved MOF-based supercapacitors.

Published: January 2024

Photosystem II (PSII) is an integral part of the photosynthesis machinery, in which several light-harvesting complexes rely on inter-complex excitonic energy transfer (EET) processes to channel energy to the reaction center. In this paper, we report on the direct observation of the inter-complex EET in a small PSII supercomplex from plants, containing the trimeric light-harvesting complex II (LHCII), the monomeric light-harvesting complex CP26 and the monomeric PSII core complex. Using two-dimensional electronic spectroscopy, we measure an average inter-complex EET time scale of 60±5 ps for excitations from the LHCII-CP26 peripheral antenna to the PSII core. The 2D electronic spectra also reveal that the transfer time scale is nearly constant over the excitation spectrum of 600-700 nm. Structure-based calculations reveal the contribution of each antenna complex to the measured inter-complex EET time. These results provide a step in elucidating the full inter-complex energy transfer network, which allows us to understand the efficiency and robustness of the PSII machinery

Published: January 2024

This research focuses on the current scenario of the Fish-Horticulture based integrated farming system (FHIFS) compared with conventional fish farming (CFF) in north west Bangladesh. Data were collected through face-to-face interviews from farmers of FHIFS and CFF. The findings reveal that fishes were cultured in polyculture systems and horticultural crops were planted in the embankment of pond. A total of 22 species of fish, 8 species of fruits and 6 species of vegetables were cultivated as integrated farming in the study area. In FHIFS the highest cultivated fish was Rui (82.76%) and the most cultivated crop was Banana (70.83%). The study also reveals that the annual hectare-1 net revenue from FHIFS was US$ 12,462.7, 2.5 times higher than CFF (US$ 4941.2). FHIFS had a higher benefit-cost ratio (BCR) of 1.70 as compared with 1.43 for CFF. The annual net revenue and BCR shows that the FHIFS is highly potential and profitable than CFF. The also findings indicate that 65.5% of the respondent experienced medium constraints. Based on the constraint facing index (CFI) the lack of proper distribution of government facilities was ranked first among all the constraints which was followed by insufficient extension services (Rank 2nd) and high cost of operation (Rank 3rd). FHIFS could be prioritized to ensure food security through proper distribution of support, minimizing operation and labor costs, and developing a community-based integrated fish farming.

When a customer’s perception of the quality of a specific product or service exceeds the customer’s expectation or desire, a positive disconfirmation occurs.
APPLICATION OF ROBUST REGRESSION FOR PORTFOLIO OPTIMIZATION
Authors: Setiawan Ezra Putranda , Rosadi Dedi
Published: January 2024

The single-index model is a portfolio optimization method that uses each asset’s beta’. In general, the beta is estimated using the return data by the least square method. However, the return data frequently contains several outliers, so the estimation resulting from the least square method is inaccurate. This study examines several beta estimators from robust regression methods, namely the least absolute value estimator, M-estimator, LMS-estimator, LTS-estimator, MM-estimator, and Tau estimator to estimate the beta of each asset and make an optimal portfolio based on this estimated value. We also evaluate the effect of robust beta estimators on the stability and performance of each portfolio. We present the Sharpe ratio and some turnover measures, namely the l-period portfolio turnover, maximum turnover, lower bound single-asset turnover, and lower bound multiple-asset turnover. Among various estimators used here, the Tau estimator is the best estimator to replace the OLS for estimating the beta.

Published: January 2024

Set theory is considered as the foundation of all mathematics since many mathematical concepts cannot be defined precisely without using set-theoretical concepts. In this study, we define new complemental binary operations, called union complements, intersection left complement, and union right complement and investigate their properties in detail. We contribute to the literature of sets by illuminating the relationships between these complemental binary operations and inclusive\exclusive complements via researching the distribution rules. Moreover, we show that the set of all the sets together with these new complemental binary operations form some algebraic structures. Finally, with the inspiration of these novel concepts, we give an application to group theory as regards subgroups by defining new type of subgroups in order to prompt the reader to think via interesting questions. Since the concept of operations of soft set theory, one of the most popular theory for uncertainty modeling in the past twenty four years, is the crucial notion for developing the theory and since all the types of soft set operations are based on the classical set operations, generation of new complemental binary operations on sets, and thus on soft sets and derivation of their algebraic properties will provide new perspectives for solving problems related to parametric data.

Self-ignition and self-heating are processes when the heat required for ignition of a substance arises in the substance itself as a result of chemical, physical or biological processes. The term autoignition should be nderstood not only as self-ignition, the ignition of a substance but as a complex, spontaneously occurring process, from the first moment of temperature rise (self-heating temperature) to reaching autoignition temperature, as a result of chemical, physical or biological processes. The result of the self-ignition process is the ignition and subsequent burning of the substance or material in a flameless or flameless manner (smouldering, incandescence). Thermal spontaneous combustion is among the most common cases of physicochemical spontaneous combustion. Thermal autoignition is a thermooxidation process that is anifested by burning (flame or flameless) after previous self-heating of substances that are heated to a temperature at which the released heat of reaction exceeds the amount and speed of heat removed to the environment.

Methods: This research used several data collection and processing including online data mining through Netlytic, online observation and semi structured interview within time period from 2021–2022.

Findings: The research’s finding portrayed results in three achievements. First, Twitter significantly created leverage empowerment in a form of community participation to improve the city quality of life. Second, community empowerment was gained through holistic process and come. Third, using Twitter as appropriated and integrated strategy is a design of community empowerment. Twitter, in particular #laporhendi can be alternatives space for community discussion and participation amongst residents and local government and lead to community empowerment. Practically, urban community has the same opportunity to access Twitter and creates dynamically interaction and communication in Twitter in many direction, one to one ways, or two ways.

Originality: Although research about social media and community empowerment has been studied for decades, many research tends to explore and focus on rural and marginal community. There were few studies emphazise and discusses from the urban community point of view.

Authors: Ijilmurun Narankhuu
Published: January 2024

The vaginal microenvironment in elderly women undergoes dysregulation due to changes in the endocrine and immune systems, thereby increasing the risk of persistent HPV infection, multiple infections, cervical lesions, and related issues. These challenges have become a focal point in clinical attention. This study aims to analyze the role of vaginal microenvironment dysregulation in the development of persistent HPV infection, multiple infections, and cervical lesions. Additionally, it seeks to explore interventions targeting the vaginal microenvironment in older women. Using a literature review method and comparative analysis, this study examines the relationship between vaginal microenvironment disorders and persistent HPV infection, multiple infections, and cervical lesions in middle-aged and elderly women. It comprehensively compares the efficacy of various interventions. According to the literature review and comparative analysis, the vaginal microenvironment is closely linked to persistent HPV infection, multiple infections, and cervical lesions in elderly women. Simultaneously, this paper explores interventions for the vaginal microenvironment in the elderly. It reveals that the vaginal microenvironment in older women can be effectively addressed through local hormone replacement therapy, active probiotics, and pH regulation. The study delves into the role of vaginal microenvironment dysregulation in the development of persistent HPV infection, multiple infections, and cervical lesions. It provides a research foundation for targeted interventions for the vaginal microenvironment in the elderly. The hope is that the discussions presented in this study can offer a more comprehensive and effective support framework for the health management of elderly women.

Authors: Du Yanhua
Published: January 2024

Objective: To investigate the effect of magnesium sulfate combined with labetalol in treating hypertension in pregnancy (HIP) and its impact on adverse pregnancy outcomes. Methods: A total of 150 HIP patients treated at the Qujing Maternal and Child Healthcare Hospital from June 2020 to June 2023 were randomly assigned using the lottery method. They were divided into the control group (treated with magnesium sulfate alone, 75 cases), and the intervention group (magnesium sulfate + labetalol combined treatment, 75 cases). Blood pressure levels, total adverse reaction rates, total adverse pregnancy outcome rates, and total adverse fetal outcome rates were compared between the two groups. Results: Compared to the control group’s diastolic (87.94 ± 4.86 mmHg) and systolic (138.52 ± 9.23 mmHg) blood pressures, the intervention group showed lower levels of diastolic (78.95 ± 3.57 mmHg) and systolic (129.88 ± 7.47 mmHg) blood pressures (P < 0.05). The intervention group exhibited a lower total adverse reaction rate (4.00%) compared to the control group (14.67%; P < 0.05). Similarly, the total adverse pregnancy outcome rate in the intervention group (4.00%) was significantly lower than that in the control group (18.67%; P < 0.05). Furthermore, the total adverse fetal outcome rate in the intervention group (6.67%) was lower than that in the control group (22.67%; P < 0.05). Conclusion: The combination of magnesium sulfate and labetalol demonstrates significant efficacy in treating HIP. It effectively lowers blood pressure, improves pregnancy and fetal outcomes, is highly safe, and deserves promotion and application.

A study was carried out to assess the quality of frozen-thawed semen using the sex separation method and the traditional method in a comparative aspect, and the authors believe that the work will be of some interest to specialists in zootechnical and biological fields, as well as to veterinary specialists. The work was carried out at the Federal Research Center for Animal Husbandry named after Academy Member L.K. Ernst and on the basis of LLC “Agrofirma Zarya”, Bogorodsky district, Nizhny Novgorod region in the period from 2017 to 2022. usng the semen of eight sires. To assess the quality of the semen, the index of nuclear DNA fragmentation (nDNA) in chromatin was determined, and the activity of spermatozoa was assessed visually and using the Biola AFS‑500 sperm analyser (ZAO Biola, Moscow). On the basis of the studies conducted, it was found that the morphology of the spermatozoa depends on the individual characteristics of the sires; the content of abnormal spermatozoa varies from 2 to 8% when collected by the traditional method and from 4.10 to 15% when collected by the sexing method. A significant difference between the sires is observed in the iDNA fragmentation index – this indicator varies from 2.66 to 8.62% and from 8.50 to 28.57%, respectively. The division of spermatozoa by sex has a direct effect on the quality indicators, leading to a decrease in their activity. This indicator is 11.2% higher in semen obtained by the traditional method than by the alternative technique. The number of abnormal cells in the semen divided by sex is 2.2% higher than in the semen collected by the traditional method, and the proportion of spermatozoa with fragmented iDNA is 7% higher. The velocity of spermatozoa in the studied doses of semen collected using the technique of sex separation was 96–113 μm/s immediately after thawing, and five hours after incubation at +38°C in a thermostat this indicator decreased to the level of 20–34 μm/s. The age of puberty of their calves obtained from the sexed semen from birth to fruitful insemination is 490 days, which is 16 days more than in group I, where heifers were obtained from the semen frozen in the traditional way (TS). The term of fruiting in heifers born from the use of the sexed semen (SS) was 273 days, while that of heifers born from the use of traditionally frozen semen (TS) was 275 days (2 days more). The age of heifers from birth to first calving in the SS group was 762 days and was 14.4 days more than in the TS group, which was 748 days.

The article highlights the problems of the importance and necessity of the permanent consumption of fresh and processed fruit and berry products, which are essential for human health as the main strategic resource of the economy of any state. The aim of the article is to demonstrate the possibilities of providing the population with fresh fruits, berries and processed products in the volume corresponding to the rational consumption norms, to determine the ways of improving the sustainable development of the domestic fruit subcomplex in the conditions of international sanctions. The methodology of the work is based on the use of official statistics, information from the Internet, as well as research of domestic scientists and economists in the field of food security. The results of the study showed that at the present stage the issues of consumption of fruit and berry products in the required quantity are relevant in all countries. The dynamics of the development of horticulture in the world and in Russia for the period 1960–2021 is analysed. It is shown that Russia has reduced its position in the area of perennial crops and gross harvest of fresh fruits and berries. At the same time, there is a positive trend in the growth of productivity, gross yield and per capita consumption in the period 2010–2021. Compared to developed countries, Russia is characterised by a low level of fruit consumption and a higher level of fruit juice consumption. The article states that it is impossible for the country to achieve self-sufficiency in the analysed products due to the following objective factors: natural and climatic conditions, rather high dependence on imports of finished products and resource components. In this regard, an integrated approach is needed, including both ways to increase domestic production and imports in amounts that do not threaten the country’s food security. The results of the article can be used to expand further scientific research in the field of providing the population with fresh and processed fruit and berry products.
