A Fast-Response Method for Determining the Amplitude of a Signal in Microprocessor Automation and Control Systems with Frequency Fluctuations
Authors: Rumiantsev Yu. V. , Romaniuk F. A. , Rumiantsev V. Yu.
Published: February 2024

In microprocessor automation and control systems, the amplitude (effective) values of the fundamental harmonic of the input signals are widely used as information parameters of the controlled quantities. They are most often determined by samples of one or a pair of orthogonal components of the signal, for the formation of which digital Fourier filters and their modifications are mainly used. At the rated frequency in the power system, these filters ensure reliable reception of the signal amplitude without additional error. If the frequency deviates from the rated one, the number of samples per signal period is not an integer and the discretization becomes asynchronous. As a result, a corresponding error appears in the amplitude of the signal, and its change becomes oscillating. With minor frequency fluctuations in the normal mode, the amplitude error is insignificant. However, in abnormal situations, the frequency can have significant variations. At the same time, in critical situations, failure of automation and control systems, as well as incorrect operation of their functional algorithms, cannot be excluded. Known methods for determining the amplitude of a signal with frequency fluctuations provide a solution to the existing problem, but they are characterized by a slow response. The proposed high-response method for determining the amplitude during frequency fluctuations is focused on using as initial information samples of instantaneous values of the cosine orthogonal component of the signal, which are formed using an appropriate digital Fourier filter. Based on these samples, the dynamic cosine and sine of the angle of one sample are calculated, the use of which in calculating the amplitude ensures its independence from frequency. Processing of the received amplitude with an amplifying element with a nonlinear coefficient makes it possible to achieve acceptable performance. The effectiveness of the proposed solution was evaluated by a computational experiment using a digital model implemented in the MATLAB-Simulink dynamic modeling environment. In this case, both sinusoidal input signals and complex ones, close to the real secondary signals of measuring transformers, were used as test actions. As a result of the research, it was found that the proposed method for determining the amplitude during frequency fluctuations has a performance at the level of a quarter of the period and provides effective elimination of frequency error both in load modes and in damage modes.
Methodology for Calculating Additional Dynamic Settlements of the Bases of Slab Foundations of Buildings and Structures from Vibrations Propagating in the Soil Environment
Authors: Povkolas K. E.
Published: February 2024

The paper provides a method for calculating additional settlements of slab foundations of existing buildings and structures from vibration-dynamic influences that arise during various construction works near them (driving piles, vibra- tory driving of sheet piling beams, soil compaction with heavy rammers and vibrating hammers), as well as from industrial equipment and transport. The technique includes the following main steps. Using the finite element method, or measured existing vibration fields, the distribution of the maximum accelerations of ground vibrations under the base of the foundation along the depth is determined and the zone in which they exceed the critical accelerations at which volumetric and shear deformations of the soil begin to appear is identified. The soil at the base of the foundation is divided into elementary layers with a thickness of no more than 1/4 of the width of the foundation. Further, according to the known vibration-compression depen-dencies (the dependence of the change in the porosity coefficient e of soil samples on the acceleration of their vibrations a), which are obtained in laboratory conditions, the settlements of each layer are determined, the summation of which gives the total value of the additional dynamic settlement Sд. If it, together with the static settlement Sст, exceeds the maximum normalized settlement values, it is proposed to use three methods to reduce or eliminate Sд – drilling injection strengthening of the zone of development of additional settlements, the use of a horizontal inertial plate or a vertical barrier made of easily compressible materials in the path of vibration propagation, the use of which reduces the intensity of vibration-dynamic impacts transmitted to the foundations under consideration.

Hoy en día vivimos en una sociedad muy superficial, donde la estética y la belleza van de la mano del glamor y el estatus de los individuos, incluso la belleza se ha convertido en un elemento muy influyente en la autoestima de las personas, y es que todo el mundo quiere verse bien, o al menos sentir que se ven así. La moda cambia constantemente y con ella surgen todos los días nuevas tendencias, que, en un mundo totalmente globalizado como el nuestro, resuena hasta el rincón más recóndito de nuestro planeta, lo cual convierte a la industria de la estética y la belleza como uno de los mercados más versátiles e impredecibles a nivel global. Como había mencionado las nuevas tendencias se esparcen rápidamente a nivel global, y por ello no es de extrañar que en Sudamérica se pueda poner de moda cortes asiáticos o maquillajes europeos. Por otro lado, es innegable que las personas no escatiman gastos cuando de belleza se trata, sobre todo el público femenino, el cual está comprobado que gasta mucho más que los hombres en accesorios de estética y belleza, y ello se ve reflejado también en la gran diversidad de artículos de belleza que existen solo para ellas. En nuestro país las mujeres gastan entre un 10% y un 15% de sus ingresos en un salón de belleza, lo cual las convierte en nuestro público objetivo, sobre todo aquellas mujeres con un ingreso por encima del promedio, si queremos especificar nos referimos a aquellas pertenecientes a un NSE A-B, y es por ello que nosotros iniciamos nuestras operaciones en nuestro local de San Borja, un distrito demográficamente hablando perteneciente a ese NSE.

Published: February 2024

Kajian tentang Islam politik adalah studi tentang konflik dan ketegangan. Islam dan politik adalah dua entitas yang tidak dapat dipisahkan begitu saja. Awal mula Islam politik dapat ditelusuri kembali ke kemunculan Ikhwanul Muslimin, yang didirikan pada 1928 di dunia Sunni-Arab Islam di Kairo. Terdapat beragam pemahaman mengenai relasi Islam dan politik ataupun Islam dan Negara. Meski demikian ada factor kesamaan dari semua kelompok Islamis adalah ambisi untuk mengubah tatanan dunia. Dalam pandangan Islamisme tatanan dunia adalah sakral, berdasarkan konsep daulah Islamiyyah, Negara yang berdasarkan syari’at, dan berdasarkan pemerintahan Tuhan untuk menggantikan kedaulatan rakyat. Mereka membangun pemahaman baru tentang Islam sebagai agama yang bersatu dengan tatanan Negara. Salah satu tokoh yang memiliki pemahaman tentang Islam dan politik adalah Ali Abd Al-Raziq. Maka, kajian artikel ini ditujukan untuk mengetahui sejauh mana konsep negara serta bagaimana hubungannya dengan Islam menurut Ali Abd al-Raziq yang dituangkan dalam bukunya al-Islam wa Ushul al-Hukum pada tahun 1925 di Mesir.

Published: February 2024

Indonesia is the most generous country. Since the time of the Islamic Kingdom, there are forms of social funds, like zakat, infaq, alms, waqf, qurban, and grants. The existence and activities of Social Organisations and Social Non-Profit Institutions (ORSOLANILA) collections and distributions of funds have so far not been taken into account in national income. Whereas their actions can help to improve the Indonesian economy. Therefore, this study aims to examine the importance of ORSOLANILA in Indonesia and support the Islamic macroeconomic theory proposed by Dumairy. The method used in this research is descriptive qualitative with the type of library research. The results of this study state that ORSOLANILA’s roles are crucial in the national economy. Comparison data between Social Fund and Real GDP shows that have the different trend. Social funds increased while Real GDP dropped in the same period. This can show that the number of social funds when included in the macroeconomic calculation as a social sector can increase the amount of GDP. So it is necessary to pay attention to the Islamic economic model in calculating national income because of its impact which is provide a mechanism for economic stabilization in situations crisis or disaster and increasing investment in social and infrastructure projects that support long-term economic growth.

From the perspective of gender institutions, what is the development of the implementation of Ijbar rights in Indonesia today? Equality, UIN Sunan Kalijaga Women's Studies Center? (3) Women's human rights degraded as a result of forced marriage as a result of the use of ijbar in marriage, based on the perspective of UIN Sunan Kalijaga's Center for Women's Studies What are the legal protections for the research? As a research type, we have adopted a field research with a statutory formal approach. The data analysis method uses descriptive analysis in multiple stages such as pre-study, data processing, data validity check and data analysis. All data were obtained by observation and interview methods. The research showed that after the enactment of the Marriage Law and the compilation of Islamic law, absolute rights to izibals became unenforceable in Indonesia. Many articles indicate that permission for newlyweds or would-be couples is an important part of the wedding ceremony itself. According to UIN Sunan Kalijaga's Center for Women's Studies, Ijbar's conception of her Fiqh There are legal grounds. The basis is in the hadiths of the Prophet found in various hadith books. As one of the concepts forming the legal basis of fiqh in relation to the rule of law, fiqh experts hold mixed opinions on forced marriage (ijbar). The Women's Studies Center at UIN Sunan Kalijaga offers her two types of legal protection in terms of Islamic law to women whose human rights have been violated as a result of marriage to Ijbar rights. First, all women have an equal right to choose a partner. Second, women may be asked by their guardians permission to marry without their knowledge or consent.

Investigating causal effects of pupil size on visual discrimination and visually evoked potentials in a Snellen eye chart task

Published: February 2024

Pupil size primarily changes to regulate the amount of light entering the retina, optimizing the balance between visual acuity and sensitivity for effective visual processing. However, research directly examining the relationship between pupil size and visual processing has been limited. While a few studies have recorded pupil size and EEG signals to investigate the role of pupil size in visual processing, these studies have predominantly focused on the domain of visual sensitivity. Causal effects of pupil size on visual acuity, therefore, remain poorly understood. By manipulating peripheral background luminance levels and target stimulus contrast while simultaneously recording pupillometry and EEG signals, we examined how absolute pupil size impacts visual discrimination and visually evoked potentials (VEP) in a task mimicking the Snellen eye chart, the most common assessment of visual acuity. Our findings indicate that both higher background luminance levels and higher target contrast were associated with improved target discrimination and faster correct reaction times. Moreover, while higher contrast visual stimuli evoked larger VEPs, the effects of pupil size on VEPs were not significant. Additionally, we did not observe inter-individual correlations between absolute pupil size and discrimination performance or VEP amplitude. Together, our results demonstrate that absolute pupil size, regulated by global luminance level, played a functional role in enhancing visual discrimination performance in a Snellen eye chart task. The differential VEP effects of pupil size compared to those of stimulus contrast further suggested distinct neural mechanisms involved in facilitating visual acuity under small pupils.
Flexor Injury Rehabilitation Splint Trial (FIRST): Protocol for a pragmatic randomised controlled trial comparing three splints for finger flexor tendon repairs

Published: February 2024

Background
Without surgical repair, flexor tendon injuries do not heal and patients’ ability to bend fingers and grip objects is impaired. However, flexor tendon repair surgery also requires optimal rehabilitation. There are currently three custom-made splints used in the rehabilitation of zone I/II flexor tendon repairs, each with different assumed harm/benefit profiles; the dorsal forearm and hand-based splint (long), the Manchester short splint (short), and the relative motion flexion splint (mini). There is, however, no robust evidence as to which splint, if any, is most clinical or cost effective. The flexor injury rehabilitation splint trial (FIRST) was designed to address this evidence gap.
Methods
FIRST is a parallel group, superiority, analyst-blind, multi-centre, individual participant-randomised controlled trial. Participants will be assigned 1:1:1 to receive either the long, short or mini splint. We aim to recruit 429 participants undergoing rehabilitation following zone I/II flexor tendon repair surgery. Potential participants will initially be identified prior to surgery, in NHS hand clinics across the UK, and consented and randomised at their splint fitting appointment post-surgery. The primary outcome will be the mean post-randomisation score on the patient-reported wrist and hand evaluation measure (PRWHE), assessed at 6, 12, 26 and 52 weeks post randomisation. Secondary outcome measures include blinded grip strength and active range of movement (AROM) assessments, adverse events, adherence to the splinting protocol (measured via temperature sensors inserted into the splints), quality of life assessment, and further patient reported outcomes. An economic evaluation will assess the cost-effectiveness of each splint, and a qualitative sub-study will evaluate participants’ preferences for, and experiences of wearing, the splints. Furthermore, a mediation analysis will determine the relationship between patient preferences, splint adherence, and splint effectiveness.
Discussion
FIRST will compare the three splints with respect to clinical efficacy, complications, quality of life and cost-effectiveness. FIRST is a pragmatic trial which will recruit from 26 NHS sites to allow findings to be generalisable to current clinical practice in the UK. It will also provide significant insights into patient experiences of splint wear and how adherence to splinting may impact outcomes.

Ideal buy-back pricing and product-quality strategies for any carbon-conscious closed-loop supply chain
Authors: Karmakar Rimi , Garai Arindam , De Kajal , Hossain MD Billal , Júlia Fodor Zita , Saha Santanu
Published: February 2024

The present study addresses a closed-loop supply chain under various carbon emission regulation policies. This article involves four key chain partners viz. a single supplier of raw materials, single manufacturer, single retailer, and single collector of the used products from the end users. Depending on the returned goods quality, the collector procures used items from customers. Unlike the existing articles, the manufacturer has two different setups for the production of both items made from newly sourced components and returned goods. A specified portion of fresh and used items goes through the same reworking cycle because the production process for both is flawed. This model has been framed under the carbon tax and the strict carbon cap regulations in order to maintain better environmental stability. A newly developed metaheurestic method namely Atomic orbital search algorithm has been implemented to determine the optimal replenishment planning and acceptance quality level, along with the corresponding numbers of deliveries among the four different chain partners and to improve the supply chain net profit. To assess how carbon regulatory policies affect the best course of action, a numerical analysis of the mathematical models is conducted, followed by a sensitivity analysis of key parameters.

The allelopathic impact of Eucalyptus spp is a pivotal factor in plant-plant interactions, particularly in arid and semi-arid ecosystems. The consideration of sowing depth in plant species becomes increasingly significant when examining allelopathic effects. This study aimed to assess the allelopathic effects of Eucalyptus camaldulensis leaf powder in conjunction with sowing depth on the germination and growth behavior of Agropyron desertorum and Onobrychis sativa. Seeds of these species were collected from Yazd province, Iran. An experimental design was implemented employing a completely randomized design (CRD) with four replications and two factors. The first factor (allelopathy) comprised five levels: 0 (control), 5%, 1%, 2%, and 3% leaf powder of E. camaldulensis in 1000 g of soil. The second factor (sowing depth) included four levels: 0.5 (control), 1.5, 3, and 4.5 cm. Data analysis utilized one-way ANOVA and Duncan’s multiple range tests. The results indicated that both allelopathy and sowing depth significantly impeded the growth of A. desertorum and O. sativa. Additionally, findings revealed that 3% leaf powder of eucalyptus exerted the most pronounced impact on the number of germinated seeds, stem length, and shoot weight in both species. Furthermore, a sowing depth of 4.5 cm was observed to be more inhibitory on the germination, shoot length, and shoot weight of A. desertorum and O. sativa compared to other depths. In conclusion, the study established that the interactions between allelopathy and sowing depth significantly constrained the growth and performance of A. desertorum and O. sativa.

In the context of global climate change and ecological restoration projects, there have been significant changes in the Fractional Vegetation Cover (FVC) in the Yellow River Basin. The growth of vegetation accelerates the consumption of water resources, further exacerbating the situation of drought and water scarcity in the Yellow River Basin, leading to increased regional water resource shortage risks. This study focuses on the Yellow River Basin in China and uses a pixel-based model to convert NDVI into an FVC datasets. It establishes a pixel-wise mathematical model for annual runoff and environmental factors based on residual analysis and methods like multiple linear regression. Climate model data from CMIP6 is used as independent variables, and in combination with the statistical model established, it provides the spatiotemporal characteristics of annual runoff in the Yellow River Basin under future climate scenarios. The results show that under four climate scenarios, the average annual runoff in the Yellow River Basin is increasing, with increases of 0.008 mm/a, 0.065 mm/a, 0.25 mm/a, and 0.24 mm/a for SSP126, SSP245, SSP370, and SSP585, respectively. From 2022 to 2040, the spatial distribution of runoff change rates is similar for SSP245 and SSP370 scenarios, with an increasing trend in upstream areas like the Qinhe and Longmen regions, with rates ranging from 6.00 to 8.61 mm/a. From 2041 to 2060, in all four climate scenarios, there is little change in the depth of runoff in the northern part of the Yellow River Basin. From 2061 to 2080, under SSP126 and SSP245 scenarios, the spatial distribution of runoff shows significant increases in the river source area and a decreasing trend in the middle reaches, with rates ranging from 4.52 to 11.39 mm/a. In the period from 2081 to 2100, the runoff change rates vary significantly under the four climate scenarios.
Unveiling Depression as a Significant Cause of Insomnia through NHANES Database and Mendelian Randomization Analysis
Authors: Qi yuwei , Tai Jun , Wang Shan
Published: February 2024

Background:
Despite the existence of shared pathophysiological risk factors, the connection between depression and insomnia remains enigmatic. This research aims to provide empirical evidence to clarify this association through a meticulous analysis using data obtained from the 2005–2008 National Health and Nutrition Examination Survey (NHANES) combined with Mendelian randomization (MR) techniques.
Methods:
Examining the connection between depression and insomnia, we utilized data from the NHANES spanning 2005 to 2008. Employing a two-sample Mendelian randomization (MR) approach with genome-wide association study (GWAS) summary statistics, our study sought to unveil potential causal relationships between depressive symptoms and insomnia. The analysis utilized the original inverse variance weighting (IVW) method along with other MR techniques to validate the established causal association. Furthermore, a multivariate MR analysis was conducted, simultaneously considering multiple variables to comprehensively explore the interplay between depression and insomnia.
Results:
Our investigation, encompassing 7,463 participants from the National Health and Nutrition Examination Survey (NHANES), utilized weighted multivariable-adjusted logistic regression. The analysis unveiled a significant positive correlation between depressive symptoms and the odds ratio (OR) of insomnia, with an effect estimate of 4.157 (95% CI, 3.449–5.022). Mendelian randomization (MR) analysis further substantiated a causal link, showing an OR of 1.375 (95% CI, 1.313 ~ 1.440) for the association between depression and insomnia. Even after excluding potential confounding variables in the multivariate MR analysis, the consistent findings bolster the credibility of evidence supporting the causal relationship. Sensitivity analyses, with a non-significant p-value (P > 0.05), underscore the robustness of the observed relationship.
Conclusion
The presence of depression increases the likelihood of experiencing insomnia.

Kernel breakage and segregation are an unavoidable phenomenon during maize loading process in the silo, and the study of this phenomenon is beneficial for solving the aeration, drying and insect control in grain storage. Distribution and segregation of broken kernels, dust, and fragments (BKDF), inorganic impurities, foreign kernels and other organic impurities were studied by maize loading process in a center-loaded silo. Maize was loaded through a vertical funnel into the silo from four drop heights (0.3, 1, 2 and 3.1 m). Samples were collected using a sampling tube inserted vertically at a Y-shaped locations along three radii of the silo for each drop heights. The difference in porosity distribution in the spatial position of the maize bulk caused by kernel breakage and segregation was determined. Higher drop heights increased the content of BKDF, and the BKDF decreased nonlinearly with the increase of distance from the center of the silo. The foreign kernels concentration near the center of the silo was higher than that near the silo wall. Inorganic impurities mainly accumulated in the 1/4 ~ 3/4 radius, while other organic impurities accumulated mostly near the wall of the silo. A nonlinear model considering kernel breakage and segregation was developed to predict the porosity distribution in the vertical and radial direction in the silo. Kernel breakage and segregation minimize the porosity at the center of the silo. The porosity of the silo center was 0.421 ~ 0.438, and it increased with the distance from the center of the silo increased.

Idiopathic pleuroparenchymal fibroelastosis (iPPFE) is characterized by upper lobe-dominant fibrosis involving the pleura and subpleural lung parenchyma. Upper-lobe lung volume (UL-volume) loss is a hallmark of iPPFE. The UL volume included dense consolidation, bronchiectasis and pleural thickening, in addition to the normal parenchyma. Therefore, we hypothesized that assessing the normal parenchymal UL volume would accurately indicate disease severity and mortality risk in patients with iPPFE. This retrospective study included two cohorts of 144 patients with iPPFE. Each lobe volume was quantitatively measured using three-dimensional computed tomography, and the normal UL volume was assessed from − 950 Hounsfield units (HU) to − 750 HU. Patients with a lower normal UL volume had significantly shorter median survival than those with higher volume (6.63 years vs. 2.88 years, p < 0.001). Furthermore, the normal lung volume decreased longitudinally, with decreases occurring predominantly in the upper lobes. In multivariate analysis, a lower normal UL volume was significantly associated with increased mortality after adjusting for age, sex and FVC. A composite scoring model including age, sex and the normal UL volume more accurately predicted the risk of death. These results suggested measuring normal UL volume provides useful information for iPPFE management by predicting mortality risk.
