Hydrothermally Synthesized ZnMgAl-Layered Double Hydroxide and Rice Husk Biochar Composites for Cu(II) and Pb(II) Ions Removal From Synthetic Wastewater
Authors: Shafiq Muhammad , Alazba Abdulrahman Ali , Amin Muhammad Tahir
Published: May 2023

The efficiency of a new composite material of the layered double hydroxide (LDH) of ZnMgAl and rice husk biochar (RHB) for the removal of Cu(II) and Pb(II) ions from synthetic wastewater was investigated in this study. The images of scanning electron microscope showed extremely fine crystalline LDH particles decorated on the rough surface of the RHB while the succesful formation of the composite adsorbent (LDH/RHB) was confirmed by the corresponding energy dispersive X-ray and the Fourier-transform infrared spectroscopy. An equilibrium contact time of 30 and 15 min for Cu2+ and Pb2+, respectively, was proposed for the optimum performance of the batch adsorption process. The dose of the LDH/RHB adsorbent was optimized at 0.4 g yielding maximum adsorption capacities of 117 and 124 mg g-1 for Cu2+ and Pb2+, respectively, with corresponding maximum removal efficiencies of nearly 94% and 99%. The initial meta concentrations was optimized at 50 or 60 mg L-1 corresponding to maximum removal efficiencies or adsorption capacities. For the changing initial metal’s concentration, the removal efficiencies remained unchanged for up to 50 mg L-1 and decreased by about 50% by increasing the initial concentrations from 50 to 100 mg L-1. The adsorption capacities observed a linear increasing trend by increasing the initial concentrations from 5 to 60 mg L-1 and remained unchanged afterward up to 100 mg L-1. A solution pH of 6.0 yielded optimum results with an increasing trend in adsorption capacities and percentage removal by changing the solution pH from 2.0 to 7.0. Based on the best-fit of the pseudo second-order kinetic model to the experimental data, the chemisorption was suggested to be the controlling mechanism of adsorption. The fitting of the Langmuir model suggested a monolayer sorption of Cu2+ and Pb2+ in addition to a heterogeneous adsorption as supported by the fitting of the Temkin isotherm. The application of the Dubinin–Radushkevich isotherm proposed a physical adsorption (mean free energy of adsorption less than 8 kJ mol−1) of both heavy metal ions on the surface of the LDH/RHB adsorbent.

It is found in this paper that ILR-RPCA-back CLR has two problems when dealing with the closure effect of geochemical data. (1) After ilr transformation, RPCA is used for processing. It can be seen from the double-plot diagram that the first principal component and the second principal component transform with the element sequence transformation, and the unique principal component cannot be calculated; (2) the score and the load are transformed into the CLR space through the U matrix. According to the formula CLR=ALR·U, the score result can correspond to the original order of elements. However, the load result obtained by the use of this formula cannot correspond to the original order of elements, and the result can only be obtained through the formula” CLR=UT·ALR”. In order to obtain the best element assemblage of porphyry copper deposit, this paper adopted the mineral assemblage of discovered deposits in Gangdese metallogenic belt for statistical analysis, and obtained that the element assemblage of porphyry copper deposit was Cu, Mo, Au, Ag, W, Bi. Then, by analyzing the singularities of the composite elements, the spatial overlay of the combined element is carried out, and C-A fractal filtering is applied to identify the anomaly and background. In order to facilitate comparison, the different minerals and ore deposit types have been analyzed, the results show that (1) in view of the porphyry copper deposits, recognition effect of combination elements are better than which single element, (2) skarn type copper deposit that it has nothing to do with the porphyry had a high degree of difference, but skarn type copper deposit related to the porphyry had a low degree of difference, (3) This method has a certain advantage over the single element method in porphyry gold deposits, and it can reduce the level of anomalies. Such an advantage is that in the aspect of anomaly evaluation of porphyry copper deposits, the level is reduced at the initial stage of evaluation to reduce the investment in such anomalies, (4) This method has limited ability to distinguish porphyry copper deposit from porphyry molybdenum deposit.

Several noninvasive vascular biomarkers have been suggested for improving the risk stratification for atherothrombotic events. To identify biomarkers suitable for detecting intermediate-risk individuals who might benefit from lipid-lowering treatment (L-LT) in primary prevention, the present study tested the association of plasma LDL-cholesterol with coronary artery calcification (CAC) Agatston score, high carotid and femoral intima-media thickness (IMT), low carotid distensibility and high carotid-femoral pulse-wave velocity in 260 asymptomatic individuals at intermediate cardiovascular risk and free of diabetes and L-LT. High or low vascular biomarkers were considered when their value was above the 95th or below the 5th percentile, respectively, of the distribution in the healthy or in the study population. LDL-cholesterol was independently associated with the CAC score =0 (OR 0.67; 95%CI 0.48-0.92, P=0.01), CAC score >100 (1.59; 1.08-2.39, P=0.01) and with high femoral IMT (1.89; 1.19-3.06, P<0.01), but not with other biomarkers. Our data confirm that in the presence of CAC score =0 in individuals at intermediate risk, L-LT can be avoided, while it should be used in those with CAC score >100. Femoral artery IMT could represent a useful biomarker for decision regarding L-LT, however the reference values according to sex and age should be established in a large healthy population

Published: May 2023

Sugarcane mosaic virus (SCMV) is a deleterious pathogen which causes widespread Sugarcane mosaic disease (SCMD) and is classified in the genus Potyvirus (Potyviridae), disseminated by the aphid vector. RNA interference (RNAi)-mediated antiviral innate immunity is a key biological process and antiviral defence system to interfere with viral genomes for controlling plant pathogens. The current study aims to analyze sugarcane (Saccharum officinarum L. and Saccharum spp.) locus-derived microRNAs (sof-miRNAs/ssp-miRNAs) with predicted potential for targeting the SCMV +ssRNA-encoded mRNAs, using ‘five algorithms’ approach. The ultimate goal in this research is to mobilize the in silico endogenous predicted sof-miRNAs/ssp-miRNAs to trigger RNAi catalytic pathway experimentally and generate sugarcane cultivars for evaluating potential antiviral resistance monitoring capability and capacity for SCMV. Experimentally validated mature sugarcane (S. officinarum, 2n = 8X = 80) and (S. spp., 2n = 100-120) sof-miRNAs/ssp-miRNAs (n = 28) were acquired for alignment with the SCMV genome. Of the 28 targeting mature locus-derived sof-miRNAs/ssp-miRNAs investigated, one sugarcane miRNA homolog, sof-miR159c, was concluded to localize potential binding site at genomic nucleotide site 3847 targeting CL ORF of SCMV. In order to validate target prediction accuracy, whether the sugarcane sof-miRNA/ssp-miRNA might bind predicted SCMV mRNA target(s), we created an integrated Circos plot. Genome-wide in-silico-predicted miRNA-mediated target gene regulatory network validated interactions that warrant in vivo analysis. The current work provides valuable evidence and biological material for generating SCMV-resistant sugarcane varieties.
CDF-LS:Contrastive Network for Emphasizing Feature Differences with Fusing Long and Short-term Interest Features

Published: May 2023

Modelling both long and short-term user interests from historical data is crucial for accurate recommendations. However, unifying these metrics across multiple application domains can be challenging, and existing approaches often rely on complex, intertwined models which can be difficult to interpret. To address this issue, we propose a lightweight, plug-and-play interest enhancement module that fuses interest vectors from two independent models. After analyzing the dataset, we identify deviations in the recommendation performance of long and short-term interest models. To compensate for these differences, we use feature enhancement and loss correction during training. In the fusion process, we explicitly split long-term interest features with longer duration into multiple local features. We then use a shared attention mechanism to fuse multiple local features with short-term interest features to obtain interaction features. To correct for bias between models, we introduce a comparison learning task that monitors the similarity between local features, short-term features, and interaction features. This adaptively reduces the distance between similar features. Our proposed module combines and compares multiple independent long-term and short-term interest models on multiple domain datasets. As a result, it not only accelerates the convergence of the models but also achieves outstanding performance in challenging recommendation scenarios.
Towards an Effective Service Allocation in Fog Computing

Published: May 2023

The Internet of Things (IoT) generates a large volume of data whenever devices are interconnected and exchange data across a network. As a result, there is a range of services with varying needs, for example, capacity requirements, data quality, and latency demands. These services operate on fog computing devices, which are limited in power and bandwidth compared to the cloud. The main challenge is deciding where to implement services on the fog, the cloud, or the hybrid. This paper proposes an efficient allocation technique that pushes processing closer to the network's fog side. It investigates which devices and services may best allocate while preserving resource usage in the IoT architecture. It also examines the importance of allocating services to devices and optimizing resource use in fog computing. In IoT settings, there is a wide range of services and devices; thus, it is critical to effectively assign the services to the devices. We propose Priority-based Service allocation (PSA) and Sort-based Service Allocation (SSA) techniques, which are used to enable an optimum order to employ devices to perform the various services. The experimental results indicate that our proposed technique minimize the data communication over the network by 82% by allocating most of the services locally in fog. We have maximized the number of distributed services to fog devices by 90% while minimizing the wastage of fog resources.

Interest in developing novel crop protectants has gained attention in the recent decade due to the hazardous effects of synthetic pesticides on humans and the environment. The citrus industry worldwide is threatened by the D. citri, the primary vector of phlo-em-limited bacterium (HLB) or citrus greening. However, there is no cure for citrus greening available. Diaphorina citri management largely depends on synthetic insecticides, but their massive application leads to resistance in pest populations. Therefore, alternative pest management strategies are needed. Our results indicated fewer D. citri adults settled on plants treated with ABEO than on control 48 h after re-lease. The psyllid fed on citrus leaves treated with ABEO significantly secreted less honeydew than the control. The essential oil showed potent ovicidal activity against the D. citri eggs with LC50 5.88 mg/mL. Furthermore, we also explore the fitness of D. citri on ABEO-treated and untreated Citrus × sinensis by using two-sex life table tools. The results indicated that the intrinsic rate of increase (r) was higher on untreated seedlings (0.10 d−1) than those treated with a sub-lethal dose of ABEO (0.07 d−1). Similarly, the net re-productive rate (R0) was higher for untreated seedlings (14.21 offspring) than those treated (6.405 offspring). Notably, the ABEO were safer against Aphis melifera, with LC50 ranging from 31.05 to 55.86 mg/mL, which is relatively higher than the LC50 24.40 mg/mL values against D. citri. Our results indicate that ABEO exhibits toxic and behavioral effects on D. citri that could be useful for managing this pest.
Legendre Series Analysis and Computation via Composed Abel-Fourier Transform
Authors: De Micheli Enrico
Published: May 2023

We prove that the Legendre coefficients associated with a function f(x) can be represented as the Fourier coefficients of a suitable Abel-type transform of the function itself. Thus, the computation of N Legendre coefficients can be performed efficiently in O(NlogN) operations by means of a single Fast Fourier Transform of the Abel-type transform of f(x). We also show how the symmetries associated with the Abel-type transform can be exploited to further reduce the computational complexity. The dual problem of calculating the sum of Legendre expansions is also considered. We prove that a Legendre series can be written as the Abel transform of a suitable Fourier series. This fact allows us to state an efficient algorithm for the evaluation of Legendre expansions. Finally, numerical tests are presented to exemplify and confirm the theoretical results.

Published: May 2023

The main purpose of tissue engineering is to fabricate and exploit engineered constructs suitable for the effective replacement of damaged tissues and organs, and able to perfectly integrate with the host’s organism without eliciting any adverse reaction. Ideally, autologous materials represent the best option, but they are often limited due to the low availability of compatible healthy tissues. So far, one therapeutic approach relies on the exploitation of synthetic materials: they exhibit good features in terms of impermeability, deformability and flexibility, but present chronic risks of infections and inflammations. Alternatively, biological materials, including naturally derived ones and acellular tissue matrices of human or animal origin, can be used to induce cells growth and differentiation, which are needed for tissue regeneration: however, this kind of materials lacks satisfactory mechanical resistance and reproducibility, affecting their clinical application.
In order to overcome the above-mentioned limitations, hybrid materials, which can be obtained by coupling synthetic polymers and biological materials, have been investigated with the aim to improve biological compatibility and mechanical features. Currently, the interest in these mate-rials is growing, but the ideal ones have not been found yet.
The present review aims at exploring some applications of hybrid materials, with particular mention to urological and cardiovascular fields: in the first case, the efforts to find a construct that can guarantee impermeability, mechanical resistance and patency will be herein illustrated; in the second case, the search for impermeability, hemocompatibility and adequate compliance will be been disclosed.

Abstract: Gastroesophageal reflux disease (GERD), the inflammatory bowel disease (IBD), and mental health issues are significant public health concerns in globally. Although rising peaks observed post-COVID-19, there is a sever paucity in high quality data. Using descriptive analysis, we identified the frequency and associations of age- and gender, sport, genetic, and psychiatric consequences in the coexistence of GERD and IBD in 2067 participants 18 to >60 years with mean age of 26.8 ± 12.9 years. Most were 18 -29 years old (66%, n=1364) of which majority were young Saudi females (72.4%, n=1496). Estimated 1099 (53.2%) were students, 428 (20.7%) were unemployed, and 540 (26.1%) were. The majority were Saudis (94.7%, n= 1957). Psychological syndromes anxiety (60.7%), stress (60.7%), and depression (60.6%) were most frequent; whereas, IBD (48.7%) and GERD (36.3%), respectively were the second and third. In 51 % respondents depression, anxiety, and stress occurred first while in 33.9%, and 24.3% IBD and GERD, respectively, were the first signs. In most respondents (59.2%, n=1178), these signs first appeared recently and 33.6% (n=669) reported occurrence during adult life, and only in 7.2% (n=144) the signs noticed during childhood (7.2%, n=144)). Aggravating factors were 32.9% (n=681) genetic and other factors of which 476 (69.9%) inherited IBD while 215(31.6%) and 175 ((25.7), respectively, inherited psychological (depression, anxiety, and stress) and GERD. However, only 18.3% sought treatment (n=378) and only 66 (3.2%) had colectomy or a colostomy bag. Little over half of the studied population (58.1%, n=1201) were active in outdoor. GERD or IBS and psychological factors (anxiety, depression, and stress), were significantly associated with age (P value =.001).; GERD with old age, IBD with mid-age 40-49 years, and psychological disorders among younger ages. Thus, while mental health issues predispose young millennial women to neurogastroenterological disorders, the IBD and GERD initiate psychological problems in old and mid-ages, respectively. Intriguingly, despite the significantly mosaic global genetic population structures, their lifestyles, and nutritional habits, the pattern of these disorders remains similar. Thus, this is potentially consistent with notion that the gut nerve cells are conserved and that the changes in gut dysbiosis of gut microbiome signatures are responsible. These findings have significant clinical implications in the patient treatment strategies and tailored educational and awareness programs in lifestyle medicine. Future microbiome studies would reveal more insight into the mechanisms of disorders.

A Meixner Alapítvány többéves kutatási projektet folytat a Meixner Ildikó (1995) által kidolgozott olvasólapok megújításához, újbóli beméréséhez. Ennek keretében 2019 májusában 1068 fő 2. évfolyamos gyermek eredményeinek a bevonásával határozta meg az erre az évfolyamra kidolgozott Meixner olvasásvizsgálati eljárás gyenge olvasási teljesítményt jelző új diagnosztikus kritériumait a tempó, a pontosság és az értő olvasás tekintetében. A felmérés során három tesztvariánst használtak fel, amelyek a szövegolvasás és -értés szubtesztben térnek el egymástól. A kutatás kitért olyan adatok gyűjtésére is, amelyek egyes, az olvasás szempontjából a szakirodalom alapján jelentősnek vélt háttérváltozókra vonatkoztak. Jelen tanulmány a C tesztváltozat 514 tanuló eredményeire támaszkodó olvasási mutatóit veti össze a rendelkezésre álló szocioökonómiai adatokkal. A településtípus és az anya iskolai végzettsége alapján képzett csoportokon végzett összefüggés-vizsgálatok rámutatnak, hogy a gyermekeknek az eltérő szocioökonómiai sajátosságok miatt már az iskoláztatás kezdő szakaszától, az írott nyelv elsajátítását követően egyenlőtlen esélyeik vannak az olvasás eszközszintű elsajátítására.

Az iskolai mondatelemzés: hogyan tovább?
Authors: Imrényi András
Published: May 2023

A tanulmány előzményét képező cikk célja az volt, hogy kimutassa a hagyományos iskolai mondatelemzés egyes továbbgondolást igénylő vonásait (miközben annak előnyeit is hangsúlyozta). A jelen írás olyan lehetséges forgatókönyveket tárgyal, amelyek az iskolai mondatelemzés jövőjét alakíthatják. Az explicit mondatelemzés visszaszorítása és a hagyományos elemzés generatívval való felváltása egyaránt előnytelennek látszik. Ezek helyett a cikk a hagyomány újító megőrzésére tesz javaslatot. Egy olyan, kognitív nyelvészeti alapokon nyugvó mondattant vázol fel, amely a kontextuális körülmények közötti jelentésképzésből indul ki, az állítmány helyett a magmondat fogalmát alkalmazza, és több dimenzióban vizsgálja a mondatalkotó elemek közötti viszonyokat.
Játékalapú tanulás és anyanyelvi nevelés az alsófokú pedagógusképzésben
Authors: Boronkai Dóra
Published: May 2023

A játékot a tanulási folyamatban már régóta felhasználja a pedagógia, napjainkban azonban egyre inkább megjelenik az a törekvés, hogy a teljes tanulási folyamat játékalapúvá váljon a különböző tantárgyak, így az anyanyelv oktatásában is. A játékalapú tanulás akár offline, akár online környezetben megvalósuló típusai a tantárgyakon átívelő jellegük miatt egyidejűleg alkalmasak a különböző keresztkompetenciák, például a szövegértés és a szövegalkotás fejlesztésére is. Ezek a tevékenységek nemcsak érdekesebbé teszik a tananyagot, hanem a diákok tanulási kedvét és eredményességét is fokozzák, így az új generációk motiválására is alkalmasak. A tanulmány a játékalapú tanulás módszertanának áttekintése után példákat mutat be arra, hogy az egyes típusokat hogyan lehet felhasználni az anyanyelvi nevelésben, és a gamifikált értékelési rendszer hogyan alkalmazható a pedagógiai gyakorlatban.

A tanulmány célja, hogy áttekintse a jelenkori alsó tagozatos fogalmazástanítás tevékenységrendszerét, az abban rejlő kihívásokat, és újszerű módszertani javaslatokat nyújtson az írásbeli szövegalkotás fejlesztéséhez. A papírszínház mint sajátos mesélési mód az alfa-generációs gyerekek számára is vonzó lehet, a pedagógusok pedig az igényes, részletgazdag papírszínházas képek segítségével különféle szövegtervezéssel vagy -szerkesztéssel kapcsolatos gyakorlatokat kínálhatnak fel az anyanyelvi órákon. A tanulmányban ismertetett módszertani javaslatok elsősorban a hagyományosabb frontális osztálymunkába integrálhatók, céljuk azonban nem a tananyag reprodukálása, hanem a fantázia felébresztésére, a kreatív gondolkodásra történő bátorítás. A képek inspirálta szövegalkotás számos területen fejlesztő hatással lehet: a fantázia gazdagításában, a belső képalkotás fejlesztésében, a nyelvi kifejezőkészség finomításában, a gondolkodás komplexebbé tételében.

Analysis of The Effect of Information and Communication Technology on the Production of Micro and Small Enterprises in Indonesia
Authors: Heryasa Taufik , Purmiyati Atik
Published: May 2023

At present, the Indonesian business world is still dominated by Micro and Small Enterprises (MSE). From the results of the 2016-Advanced Economic Census, the number of these businesses reached more than 26 million businesses or 98.68 percent of the total non-agricultural businesses in Indonesia. This business is also able to absorb more than 59 million workers or around 75.33 percent of the total non-agricultural workforce. The advantages of MSEs include generally producing consumer goods and services that are close to the needs of the community, not relying on imported raw materials and more utilizing local resources both in terms of human resources, capital, raw materials, and equipment, and using their own capital or not supported by loans. from the bank. On the other hand, the limitations of MSEs include the lack of access to banking, the ability and knowledge of human resources that are still low so that they are managed in a simple way, the use of limited technology, and has not been able to keep up with changing consumer tastes, especially those that are export-oriented. The rapid development of information and communication technology has an impact on changes in lifestyle, including consumption patterns and the way people sell and shop. The phenomenon of e-commerce provides an easy way to shop for people by not having to come directly to the store. This can be used by MSEs to reach larger consumers so as to increase their production and income. This study aims to analyze the effect of Information and Communication Technology on the production of Micro and Small Enterprises in Indonesia. This study uses panel data from 34 provinces in Indonesia between 2015-2020 which is estimated using the Generalized Method of Moments (GMM). The results show that capital, labor, computer users, fixed wireline users, cellular phone users, internet users and telecommunications expenses simultaneously have a positive and significant impact on the production of Micro and Small Enterprises in Indonesia. Partially, capital has a positive and significant effect on the production of Micro and Small Enterprises in Indonesia. On the other hand, telecommunications spending has a negative and insignificant effect on the production of Micro and Small Enterprises in Indonesia. While other variables have a positive and insignificant effect on economic growth in Indonesia. With these results, it is hoped that the government will issue policies to support micro and small businesses in increasing the use of information and communication technology to increase their production. Among other things, by building telecommunications infrastructure in areas that are not yet adequate, providing education to micro and small business actors in using information and communication technology, and providing light credit in the form of smartphones and computers to micro and small businesses so that they can be used to promote their products on the internet.

Published: May 2023

Local tax revenue is the largest source of local revenue. Conditions in Ponorogo Regency in the local tax revenue sector have decreased in 2020 due to the Covid-19 pandemic. The government must prepare a strategy and design to recover lost tax revenues in 2020. Projections are made to find out the amount of local tax revenue, especially in Ponorogo Regency in the coming 2022-2026. This study aims to calculate and project the value of regional tax revenue for Ponorogo Regency in 2022-2026 and design activities so that these projections can be fulfilled. Secondary data obtained from the Office of Revenue, Financial Management and Regional Assets of Ponorogo Regency. The largest revenue from the Regional Tax for Ponorogo Regency in 2013-2021 is land and building taxes with a total of 250,443,706,350 and the lowest is the groundwater tax post which only reaches 1,862,439,630. However, after making projections for 2022-2026 the largest tax post occurs in total hotels with a value of 6,072,824,558 and the lowest tax post occurs with a parking tax of 722,938,090. The value of the highest tax item has changed in the hotel tax post as well as the hidden tax item in the parking tax which has changed in its entirety from before the projection was carried out. So it is necessary to renew new activity programs in order to increase tax items that are still low and maintain tax items that are already large.
Corruption and FDI Inflows in Indonesia
Authors: Yohannaa Cynthia , Suyanto Suyanto
Published: May 2023

The inflows of Foreign Direct Investment (FDI) to a country depend on many factorszzne of the crucial factors is the corruption index, which represents a pivotal aspect in Global Investment Competitiveness (GIC). This research analyzes the impact of the corruption perception index on FDI inflows to Indonesia. Other variables affecting FDI are Gross Domestic Product (GDP), inflation rate, and population. Vector Error Correction Model (VECM) is used to estimate the time series sample between 1995 and 2019. Following the time series procedure, several tests are conducted on the dataset before applying VECM: unit-root, optimum lag, and cointegration. The main finding shows that the higher the corruption index, the higher the FDI Inflows, implicating that low corruption attracts more FDI inflows to Indonesia. Other findings are that an increase in GDP attracts more FDI, an increase in inflation rate reduces FDI inflows, and an increase in population increases FDI inflows. The policy implication of the findings is related to an effort in attracting more FDI inflows requires a substantial endeavor in combating corruption and increasing the Corruption Perception Index of Indonesia from time to time.

But the data will provide additional support to suppress the assumption and improve the models. So, an optimized project ahead model that combines geometry, bottomhole assembly (BHA) dynamics and dynamic earth model is needed for a practical project ahead prediction. This paper presents a coupled model with embedded uncertainty not only for projecting ahead the path but also steering to achieve the path. This paper presents the results that can be used under uncertainty through planning, through realtime project ahead, most importantly by integrating all the above four models.

Planning and executions are two primary approaches to intelligent decision making at the edge when the well is constructed. Execution enables us to take immediate actions far into the future, but it requires accurate well trajectory models, and the current and past realtime data. When it comes to the edge decision whether it is manual or semi-automated or fully automated it requires tighter coupling of engineering models through microservices and reinforced learning from the data and feedback from the driller. Four major types of models are considered in this paper to arrive at the dynamic path as the well is drilled. 1. Soft landing path based on dogleg as constraint 2. Minimum well profile energy that can be achieved 3. Mechanical drillahead model based on the steering tool 4. Productivity coupled earth model for various input parameters from earth model to operational parameters during drilling.

Drilling becomes extremely challenging when dealing with naturally fractured reservoirs (NFR). A comprehensive solution is developed in this study to perform qualitative analysis on drilling fluid loss rate and volume to examine how they can be affected by NFR characteristics, drilling fluid rheology, leakoff phenomenon, and wellbore condition. In this regard, the solution is applied to generate type curves to facilitate the sensitivity analysis (refer to the provided Supplementary Materials). The presented solution accounts for not only drilling fluid pseudoplasticity in the total system but also matrix medium under wellbore constant pressure assumption (by including dimensionless matrix contribution parameter). It is also able to measure mud loss advancement not only through NFR but also through homogeneous reservoirs. The developed solution is validated by reducing it to the preexisting solution (designed for Newtonian fluid case) by incorporating assumptions into it. The result demonstrates the significance of NFR properties and drilling fluid pseudoplasticity on the leakoff phenomenon and total loss volume, especially when constant pressure is established inside the wellbore. The finding reveals that three periods can be identified through generated type curves depending on NFR characteristics, drilling fluid rheology, and leakoff coefficient. Therefore, different drilling fluids with specific pseudoplasticity should be used in each period to mitigate drilling fluid loss effectively. In this regard, the study is supposed to design drilling fluid in a way to maintain its pseudoplasticity at a higher level at early and late times, while being maintained at a lower level during the transient period, a critical aspect for managed pressure drilling techniques, particularly in the context of dual-gradient drilling applications. Additionally, a procedure should be implemented to lessen the transient period while attempting to keep drilling fluid advancement occurrence at a lower rate, which shows that drilling fluid pseudoplasticity can be used as an effective tool to manage this period. The obtained result also indicates that the importance of drilling fluid rheology to control total loss volume is greater for NFR with higher leakoff than with lower leakoff. Furthermore, the greater the differential pressure inside the wellbore, the greater the importance of mud rheology to reduce drilling fluid loss. The outcome of the study not only facilitated qualitative and quantitative analyses through NFR but also enabled decision-makers to instantaneously select optimal wellbore conditions and drilling fluid pseudoplasticity.

Bound states in the continuum (BICs) are a well known phenomenon in physics, particularly in quantum physics and wave physics. Since BICs are local states, their existence typically manifests as Fano resonances in the transmission or reflection spectrum. However, to date no direct or visual proof of an acoustic BIC has been reported. We demonstrate the existence of a Friedrich-Wintgen BIC in an open acoustic cavity by theory and experiments. The appearance of the BIC is characterized by the vanished line width of the Fano resonance in the measured transmission spectrum. Our theoretical predictions accurately match the experimental observations. We map the pressure field of the transparent open cavity hosting a Friedrich-Wintgen BIC using laser Doppler vibrometry, which is the first reported visualization of an acoustic BIC. Mapping the pressure field of the BIC is a new technique to extract real sound pressure values of high-Q modes. We can draw conclusions from the pressure values on the confinement of the BIC. Our results facilitate the future development of applications of BICs in the field of acoustics, as acoustic sources, filters, and sensors.

Geophysical investigations are one of the leading efforts in any exploration project that must be performed ahead of time due to the high excavation expenditures, heavy machinery, and cost reduction. One of the essential geophysical concerns is the estimation of the physical and geometrical parameters of the reserve (geobody), which is done by exploiting the nonlinear inverse modeling of magnetic data. These parameters include depth, volume, shape factor, and type of storage. The present investigation aims to prepare and model magnetic data for proposed drilling sites in the Baba Ali Iron ore deposit in the Hamedan province of Iran. The area is covered with 1000 points of geomagnetic reading with an almost 5*10 m regularly spaces grid trending WE. The areal and depth extent of the iron ore geobody was unknown. The Bhattacharyya method by MATLAB software coding was used to minimize the target function and potential field data and create the best fit for the measured and modelled magnetic data. The residual anomaly and model graphs exhibited an excellent two-dimensional conformation in this modeling. Also, 3D modeling correctly reconstructs the properties of the productive resources of anomalies. After preparing full magnetic maps, the magnetic lenses distinguished in four anomalies of surface depths, 20, 50, and deeper than 50 meters for this zone. This magnetite lens for the first zone was estimated based on analytical signal filters applied on the entire magnetic map so that the lens's depth is trivial and almost zero. Due to specific gravity calculated as 4.77 t/m3, initial storage capacity is suggested to be about 95,400 tons of magnetite, pyrite, and hematite minerals at most in an area about 6 Km2. Finally, to complete the preliminary explorations of the specified area, exploratory drilling is suggested for three points by inverse modeling.

Noise cancelation is the process done to remove out-of-range anomalies and make better edge boundaries interpretation. One of the most challenging issues in describing gravitational maps is separating the anomalies related to shallow sources from the deep ones. Furthermore, Existing noise can make it arduous to separate shallow blurred boundaries. In this study in SE Iran, gravitational surveying was carried out in shallow areas from the west of Qeshm to the Hormuz islands in a regular network with a distance of one kilometer. The range of gravitational Bouguer was -297 to -330 mGal. Modeling and determining geometrical parameters revealed five negative anomalies from salt penetration. The residual gravity was computed by deducting gravitational effects related to deep sources from measured gravitational data. Correspondingly, estimating the boundary and edge of the subsurface masses will be better than local filters, and anomalies will be highlighted with more intensity. Furthermore, three major fault systems in the Zagros basin were determined as the primary origin of activity and expansion of Hormuz salt. Sensitivity analysis was employed utilizing analytical signals and maps of tilt angle filtering, which both revealed the same satisfying results of -297 to -330 mGal. In this article, the effect of the tilt angle local phase filter on a synthetic model was accomplished through numerical coding. As a result, Total Horizontal Derivative (THDR) provides location of salt intrusion in Qeshm area; whereas the best image of salt intrusion, in terms of feature edge illumination, presented by Analytical signal of residual gravity map.

Background Homozygous familial hypercholesterolaemia (HoFH) increase risk of premature cardiovascular events and cardiac death. In severe cases of HoFH, clinical signs and symptoms cannot be controlled well by non-surgical treatments, liver transplantation (LT) currently represents the viable option.Method To assess the clinical efficacy, prognosis and optimal timing of LT for HoFH, a retrospective analysis was conducted on the preoperative, surgical conditions and postoperative follow-up of children who received a LT for HoFH at the Beijing Friendship Hospital over the period from December 2014 to August 2022.Results Xanthoma and decreased activity tolerance were the primary clinical manifestations in the 7 HoFH children initially assessed (one child died suddenly prior to surgery due to cardiac arrest). Accompanying these symptoms were increased blood total cholesterol(TC) and low density lipoprotein (LDL) levels, along with severe cardiovascular diseases. HoFH was confirmed in all cases by genetic and biochemical assays. Initial treatments administered to these patients consisted of low-fat diets and lipid-lowering drugs with poor outcomes. Accordingly, all 6 patients received orthotopic liver transplantations(OLT), with the result that significant postoperative reductions were observed in levels of TC and LDL. The median follow-up of these six cases was 37.41 months (range: 19.40 to 94.10 months). Regular postoperative follow-ups revealed that all children survived, were in good health and showed significant improvements in their clinical symptoms.Conclusion LT can serve as an effective means for treatment of HoFH in children. This LT should be performed prior to the onset of cardiovascular diseases to achieve maximal effects in improving the quality of life for these children.

Based on the research and investigation of the psycho-educational development and assessment of college students, this paper designs an interactive system for automatic evaluation of the psychoeducation of college students, which is based on the KNN data classification model and the current technical and environmental conditions. Based on the data and personal information of a college student's psychological census, screen the students' psychological evaluation data, analyzes the key information of the data, obtains the association rules of each factor, analyzes the experimental results. Aiming at the problem that KNN algorithm has low classification accuracy on unbalanced data, we proposes a weighted KNN hybrid algorithm. The harmonic weighted KNN classifier is added to the SVM-KNN classifier for fitting, and the SVM-KNN hybrid algorithm is jointly established. Combined with the principle of SVM-KNN hybrid data classifier, the improved algorithm is applied to a wider range of data value areas, and the appropriate algorithm is selected for data classification and prediction by judging the threshold size. For the data classification calculation method, the Euclidean distance calculation method is generally used to calculate the point-to-point distance in the plane coordinate system, as for hyper plane high-dimensional data, the improved algorithm uses a more suitable kernel function calculation method. According to the designed experimental step program, a series of basic performance such as the calculation rate of the algorithm and the system are tested, and the results show that it can be satisfied, which proves that the interactive automatic evaluation system of College Students' psychological education designed in this paper can effectively understand the psychological status of college students at this stage, find the students who need to focus on psychological counseling, and carry out psychological health education, so as to provide reference for the actual college students' psychological health education.
