Variable substitution methods in the solution of stochastic ordinary differential equations and their applications
Authors: Zhang Ting
Published: November 2023

In this paper, we first propose numerical solution methods for stochastic ordinary differential equations by using the two-step Maruyama method and Euler-Maruyama method in variable substitution, and analyze the mean-square compatibility, mean-square convergence and mean-square linear stability of the corresponding numerical methods, respectively. Finally, 10,000 times value experiments are conducted to verify the convergence accuracy and stability of the variable substitution methods. The results show that the Euler method simulates this equation when taking steps h = 0.05, β = 5 and σ = 2 for numerical experiments, and the numerical results obtained are convergent but unstable. On the other hand, the Euler-Maruyama method with variable substitution is consistent with the real solution. It shows that variable substitution is an important method for solving stochastic ordinary differential equations with high convergence and stability, which is of great significance for the solution of stochastic ordinary differential equations.

Investigation of the correlation of midpalatal suture maturation stage with chronological age and cervical vertebral maturation stage
Authors: Yang Chin-Chen , Chen Meng-Yen , Liu Jia-Kuang , Chang Chen-Jung
Published: November 2023

Objectives:

The first aim of this study was to investigate the correlation between chronological age, cervical vertebral maturation (CVM) stage, and midpalatal suture (MPS) maturation stage. The second aim was to assess the relationship between the prognosis for rapid maxillary expansion (RME) and age, CVM stage, and MPS maturation stage.

Material and Methods:

We divided 109 participants into three age groups: <15 years, 15–25 years, and >25 years. The participants had undergone both cone-beam computed tomography (CBCT) and lateral cephalometric X-ray examination. Their MPS maturation stage was classified as A to E and CVM stage as cervical stage 1 (CS1) to CS6, according to a previously proposed method. We used the weighted kappa coefficient to assess intra-examiner agreement and Spearman’s correlation coefficient, to evaluate the correlations of MPS maturation stage with age and CVM stage.

Results:

The weighted kappa coefficients were 0.849 and 0.923 for the identification of MPS maturation stage and CVM stage, respectively. There were significant, but weak correlations between MPS maturation stage and age (r = 0.313, P = 0.001) and, CVM stage (r = 0.287, P = 0.002). MPS stage C was the most prevalent across all age groups and all CVM stages.

Conclusion:

Chronological age and CVM stage may not accurately predict MPS maturation stage, especially in older patients. Further, the prognosis for RME may not be strongly related to either CVM or MPS maturation stage. We recommend using CBCT X-rays for individual MPS assessments before selecting the type of maxillary expansion treatment.
Nonlocal Boundary Value Problem for an Equation with Fractional Derivatives with Different Origins
Authors: Энеева Л.М.
Published: November 2023

Рассматривается линейное обыкновенное дифференциальное уравнение дробного порядка с композицией лево- и правосторонних операторов дробных производных в главной части. Уравнения, содержащие композицию операторов дифференцирования дробного порядка с различными началами, появляются при моделировании различных физических и геофизических явлений. К их появлению приводит использование понятия эффективной скорости изменения параметров моделируемых процессов. В частности, уравнения рассматриваемого в работе вида возникают при описании диссипативных колебательных систем. Дробное дифференцирование понимается в смысле РиманаЛиувилля и Герасимова-Капуто. Для исследуемого уравнения изучается нелокальная краевая задача. Нелокальное краевое условие задано в форме интегрального оператора от искомого решения. При определенном условии на ядро оператора, фигурирующего в нелокальном условии, рассматриваемая задача эквивалентно редуцируется к интегральному уравнению Фредгольма второго рода. Найдены достаточные условия разрешимости исследуемой задачи, включающее интегральное ограничение на переменный потенциал. В качестве следствия получено неравенство Ляпунова для решений рассматриваемой нелокальной задачи. Показано, что возникающее в решении задачи условие на ядро интегрального оператора из нелокального условия, является необходимым, в том смысле, что при нарушении этого условия единственность решения задачи теряется.

We consider a linear ordinary differential equation of fractional order with a composition of left and right-sided fractional derivative operators in the principal part. Equations containing a composition of fractional order differentiation operators with different origins appear when modeling various physical and geophysical phenomena. Their appearance is caused by the use of the concept of the effective rate of change in the parameters of the simulated processes. In particular, equations of the type considered in this work arise when describing dissipative oscillatory systems. Fractional differentiation is understood in the sense of Riemann-Liouville and Gerasimov-Caputo. For the equation under study, a nonlocal boundary value problem is investigated. The nonlocal boundary condition is specified in the form of an integral operator of the desired solution. Under a certain condition on the kernel of the operator appearing in the nonlocal condition, the problem under consideration is equivalently reduced to the Fredholm integral equation of the second kind. Sufficient conditions for the unique solvability of the problem under study are found, including an integral constraint on the variable potential. As a corollary, the Lyapunov inequality for solutions to the nonlocal problem under consideration is obtained. It is shown that the condition on the kernel of the integral operator from the nonlocal condition that arises in the solution of the problem is necessary in the sense that if this condition is violated, the uniqueness of the solution to the problem is lost.

Published: November 2023

В работе проведено исследование хаотических и регулярных режимов дробного осциллятора Дуффинга с помощью алгоритма Тест 0-1. Дробный осциллятор Дуффинга описывается нелинейным дифференциальным уравнением с производной Римана-Лиувилля дробного переменного порядка. С помощью явной численной конечно-разностной схемы получено численное решение модели, которое подается на вход алгоритма Тест 0-1 после процедуры прореживания – выделения локальных экстремумов. Далее с помощью пакета Matlab реализуется алгоритм Тест 0-1 и проводится визуализация результатов моделирования. Строятся бифуркационные диаграммы для коэффициента корреляции с учетом значений порядков дробной производной, строятся осциллограммы и фазовые траектории. Показано, что алгоритм Тест 0-1 работает корректно при соответствующем выборе шага дискретизации.

The work carried out a study of chaotic and regular modes of a fractional Duffing oscillator using the Test 0-1 algorithm. The fractional Duffing oscillator is described by a nonlinear differential equation with the Riemann-Liouville derivative of a fractional variable order. Using an explicit numerical finite difference scheme, a numerical solution to the model was obtained, which is fed to the input of the Test 0-1 algorithm after the thinning procedure – identifying local extrema. Next, using the Matlab package, the Test 0-1 algorithm is implemented and the simulation results are visualized. Bifurcation diagrams are constructed for the correlation coefficient, taking into account the values of the orders of the fractional derivative, and oscillograms and phase trajectories are constructed. It is shown that the Test 0-1 algorithm works correctly with the appropriate selection of the sampling step.
The Cauchay Problem for a Loaded Partial Differential Equation of the First Order
Authors: Аттаев А.Х.
Published: November 2023

Как хорошо известно, наличие характеристик является очень существенным при исследовании задачи Коши для дифференциальных уравнений с частными производными независимо от его порядка. В случае, если дифференциальное уравнение с частными производными является нагруженным, то для однозначной разрешимости задачи Коши возникают дополнительные условия разрешимости, зависящие от вида следа нагрузки. Эти условия возникают даже для простейших линейных нагруженных дифференциальных уравнений с частными производными, начиная с первого порядка и выше. Основная цель данной работы – проиллюстрировать возникающие эффекты на примере исследования задачи Коши для линейного нагруженного уравнения в частных производных первого порядка. Так как корректность поставленной задачи Коши эквивалентным образом редуцируется к интегральному уравнению второго рода, то основной метод, применяемый для доказательства его разрешимости – метод последовательных подстановок. Основной вывод заключается в том, что разрешимость задачи Коши для нагруженного уравнения в частных производных существенным образом зависит от выбора следа нагрузки. В случае, когда разрешимость задачи Коши доказана, оказывается, что область влияния данных Коши не ограничивается только характеристиками, а появляются новые не характеристические линии, за которые данные Коши однозначно продолжаться не могут.

As is well known, the presence of characteristics is very significant in the study of the Cauchy problem for partial differential equations regardless of its order. In the case where the partial differential equation is loaded, additional conditions dependent on the type of load arise for the unique solvability of the Cauchy problem. These conditions arise even for the simplest first and higher order partial differential equations. The main purpose of this paper is to illustrate the effects arising from the study of the Cauchy problem for the linear loaded first-order partial differential equation. Since the correctness of the Cauchy problem is equivalently reduced to the integral equation of the second kind, the basic method is used to prove its solvability – method of successive substitutions. The main conclusion is that the solvability of the Cauchy problem for a loaded partial derivative equation essentially depends on the choice of the load. In the case when the solvability of the Cauchy problem is proven, it turns out that the area of influence of the Cauchy data is not limited to the characteristics only, but new non-characteristic lines appear, beyond which the Cauchy data cannot clearly be extended.

Aim. Demonstration the possibility of practical application of the highly sensitive tumor marker CA-62 in the initial diagnosis in asymptomatic patients with suspected cancer and/or the presence of pathological changes in instrumental studies, as well as describe the criteria for interpreting the results to help the doctor make a decision.
Materials and methods. The article used the results and conclusions of blind clinical trials conducted to detect early stages of breast cancer (BC), prostate cancer (PC), colorectal cancer (CRC) and non-small cell lung cancer using the CA-62 tumor marker and other tumor markers. Statistical analysis was performed using the MedCalc program (MedCalc Software Ltd, Belgium). Diagnostic efficiency was assessed in terms of sensitivity, specificity, test accuracy, PPV and NPV, ROC analysis. The significance level was taken as p0.001.
Results. The use of the standard cut-off value of 5000 U/ml of the CA-62 tumor marker makes it possible to achieve 97% sensitivity with 95% specificity in stage I BC. The combination of tumor markers CA-62 and CA 15-3 allows achieving 100% specificity in differentiation of BC and benign breast hyperplasia. The use of the CA-62 marker (6500 U/ml) in the gray zone of PSA 2.510 ng/ml improves the accuracy of detecting PC in biopsy from 35 to 93.1% with 90% sensitivity and 97% specificity. The use of a combination of tumor markers (CA-625000 U/ml, CYFRA 21-12.5 ng/ml and CEA5 ng/ml) will allow the doctor to improve the efficiency of differentiating lung cancer from chronic obstructive pulmonary disease. The combined use of markers (CEA3.5 ng/ml) and (CA-625000 U/ml) achieves 100% specificity with 97% sensitivity in detecting early stages of CRC.
Conclusion. The article shows the possibilities of using the CA-62 marker, as well as new algorithms for the detection and differentiation of early stages of BC, PC, non-small cell lung cancer and CRC and benign neoplasms using the CA-62 marker in primary diagnosis. The use of the CA-62 tumor marker or its combination with other diagnostic methods can be a useful strategy for a comprehensive assessment of the risk of malignant neoplasms and increasing the diagnostic sensitivity of detecting early stages of cancer.

Authors: Ognerubov Nikolai A. , Antipova Tatiana S. , Abakumova Galina N.
Published: November 2023

Background. Primary hyperparathyroidism is a common endocrinological disease caused mainly by parathyroid adenoma. The main treatment method is surgery (parathyroidectomy). Therefore, the exact determination of adenoma localization is crucial.
Aim. To evaluate the current possibilities of multimodal diagnosis of parathyroid adenomas.
Materials and methods. A retrospective analysis of 49 patients with primary hyperparathyroidism aged 24 to 82 (median 57.9 years) was performed. Modern radionuclide and hybrid technologies were used for topical diagnosis and metabolic assessment of parathyroid adenomas: scanning, single-photon emission computed tomography, single-photon emission computed tomography combined with computed tomography, positron emission tomography combined with computed tomography with 18F-deoxyglucose and 18F-choline. The diagnosis of primary hyperparathyroidism was confirmed by a biochemical blood test: the level of parathyroid hormone and ionized and total calcium.
Results. The study included 43 (87.8%) females and 6 (12.2%) males. The female/male ratio was 7.2:1. Most cases (78.1%) were the hypercalcemic type of primary hyperparathyroidism, and the normocalcemic type was diagnosed in 21.9% of patients. The mean parathyroid hormone level was 145.43 pg/mL, exceeding the reference values by 2.2 times. Parathyroid hormone concentration in patients with primary hyperparathyroidism was 156.38 pg/mL, and mean ionized and total blood calcium levels were 1.43 and 3.04 mmol/L, respectively. The asymptomatic type occurred in 76.7% of patients. The symptomatic type of hyperparathyroidism had 23.3%, manifested with nephrolithiasis, pancreatitis, and bone lesions. Parathyroid adenomas were more often located in the left lobe (42.9%). In 77.6% of patients with primary hyperparathyroidism, solitary adenomas were detected. Ectopia of the parathyroid glands was detected in 16.3% of patients, with intrathyroidal location in the left lobe being the most common. Rare locations include the anterior and posterior mediastinum and the esophageal wall.
Conclusion. Modern diagnostic multimodal options based on radionuclide and hybrid technologies are crucial in the personalized treatment of primary hyperparathyroidism.
Sleeve gastrectomy versus endoscopic intragastric balloon in decreasing weight and associated comorbidities in Erbil city: A comparative study
Authors:   Department of Surgery,College of Medicine, Hawler Medical University, Erbil, Iraq, Saeed Ahmed Baderkhan
Published: November 2023

Background: Surgical obesity treatment is difficult for both surgeons and patients. The three main categories of bariatric surgery procedures are malabsorptive, restrictive, or both in combination. Intragastric balloon (IB) is an easily applicable restrictive interventional and nonsurgical strategy for obese patients, and the surgical procedure known as laparoscopic sleeve gastrectomy (LSG) is frequently used to help obese patients decrease weight. Objective: To assess and compare these two restrictive approaches. Patients and Methods: A prospective study of 138 LSG patients was conducted, (n=82) and IB (n=56) between 1st January 2016 to 31st December 2021 in private hospitals in Erbil, Iraq. The study retrospectively evaluates patients' demographic information, changes in total body weight (TBW), changes in body mass index (BMI), and percentage of excess weight loss (%EWL), morbidities and change of comorbidities during a year of follow-up, at months 1, 3, 6, and 12 after surgery. Comparative analysis was undertaken for the follow-up results after 6 and 12 months. Results: In the IB group, 12 patients did not tolerate insertion, leaving 56; in the LSG group, 82 patients completed treatment. In terms of age (p=0.121), gender (p=0.242), and BMI (p=0.078), there were no statistical differences between the IB and LSG groups. The LSG group achieved statistically significant superior treatment outcomes in terms of changes in TBW, BMI, and %EWL. Conclusion: Both LSG and IB are beneficial in the short term for helping obese patients lose weight. IB has the benefit of being performed as an outpatient procedure with less complications, but it is less successful in helping people lose weight than LSG. The best options for various patient groups in terms of clinical outcomes and health system effectiveness must be determined through prospective, randomized control studies.

Steganography is a method used to enhance the security of messages across networks, derived from the Greek words steganos (secret) and graphic (writing). Researchers have explored image steganography, a method that uses a photo as a cover material. The modern energy grid, known as the smart grid, offers flexibility, dependability, and efficiency in power production and distribution. To protect privacy and confidentiality, a greyscale cover picture is subjected to discrete wavelet transformation (DWT), while a chaotic map is applied to the secret image. This method offers more security and can shield communication from stegoimage attacks. Additionally, a novel approach to disguise an image is presented to combat cryptography and steganography algorithms attacks.

Introduction. Asymptomatic bacteriuria (ABU) occurs in 2–15% of pregnant women, but opinions about ABU in pregnant women are controversial. The aim of the study was to assess the outcomes of delivery in pregnant women with ABU, depending on the therapy and urological history. Material and methods. The histories of childbirth of 46 women with ABU detected during prenatal screening, were analyzed. The outcomes of pregnancies were analyzed, and the relationship between the presence of ABU, the type of therapy, the presence of pyelonephritis in history and the development (exacerbation) of pyelonephritis during pregnancy was determined. Results. The structure of uropathogens was typical: E. coli was found in 36 cases (78.3%), Enterococcus faecalis - in 10 cases (21.7%). Seven women (15.2%) had a history of chronic pyelonephritis, 4 (8.7%) had chronic cystitis. The remaining 35 pregnant women (76.1%) had no any urological diseases. More than half of pregnant women with ABU (32/69.6%) received Сanephron; all of them had normal delivery. The average weight of newborns was 3768±101.9 grams. The rest of the 14 (30.4%) pregnant women with ABU, including 7 patients with a history of pyelonephritis, received amoxicillin with clavulonic acid. In more than half of the them (4/57.1%) gestational pyelonephritis developed. Correlational analysis showed that the low weight of the newborn, the development of gestational pyelonephritis and the likelihood of preterm birth did not depend on the therapy for ABU (antibacterial or herbal medicine), but on the presence of chronic pyelonephritis in the pregnant woman. Conclusion. The detection of ABU in a healthy pregnant woman without urological history is not a convincing basis for prescribing antibiotics. Preventive phytotherapy with the drug «Canephron» in such women was sufficient; none of the cases developed gestational pyelonephritis or preterm labor

The small black house and garden ant, Monomorium (Holcomyrmex) criniceps Mayr. is well known in almost all areas in South India occurring round about houses and in dry gardens. Although its life history and habits are known from other parts of the world, not much is known from South India. The observations on the ant made in Coimbatore are given in this paper. This is one of the commonest species occurring in dry and hard soil in fields, gardens and pathways around houses. It is usually found carrying grains in farm houses. On account of this habit, the whole group of Holcomyrmez has attained great importance as harvesters. Wheeler (1910) found that the hairs on the labium were greatly elongated and directed forward and concluded that the arrangement must aid in the carrying of the grains. By its varied food and its attendance on injurious insects like aphids it becomes one of the most important insects in this region.

The Lower Buavanı Project covers an area of 2.07 lakh acres of land situated in the taluks of Gobichettypalayam, Bhavani, Erode and Dharapuram in Coimbatore District and a portion of Karur taluk in Tiruchirapalli district. Before the advent of the Project, a major portion of the tract was grown with inferior varieties of cotton like Nadam and Bourbon along with other dry crops. Under the project, the ryots were allowed to cultivate half their holdings with Cambodia cotton. Thus Cambodia cotton came to be cultivated under irrigation in an area of about one lakh of acres every year. This sudden switch over from rain-grown cotton to irrigated Cambodia under the project conditions necessitated information on the optimum time of sowing cotton in the Lower Bhavani Project Area.

The spinning, weaver or the red tree ant- Oecophylla smaragdina (Fabricius) is a familiar ant occurring in mango and other trees in the neighbourhood of houses. On account of its peculiarities a large amount of literature on its activities and habits has been published. Yet, its importance in agriculture, life history and habits have not been fully investigated. Therefore observations made on the ant in this region are given herounder. The nesting and food habits were olaborated by the early workers like Wroughton (1892-1893) and the spinning capacity by Aitken, (1889), Green (1903) and Doflein (1905). Further work on its behavioural patterns have been summarised by Morley (1953).

Sorghum vulgare is one of the major millet crops of the Madras State grown for grain and for fodder. In Coimbatore where irrigation facilities are available it is grown as a summer erop under irrigation and as a rainfed crop in the N. E. monsoon season. The summer crop is subject to the attack of tlie earhead bug Calocoris angustatus D. which sucks up the sap from the newly formed grain and makes it chaffy. It has now become a regular practice to apply B. Н. С. 10% dust once a week at the time the carheads are exerted so as to control the bugs. However, other insects which had so far been occupying a subsidiary status, are becoming important now. Many species of Lepidopterous larvae have been found in the internal portions of the compact earheads feeding on the grains in the security of the spikelets which surround them. Attention has been drawn to some of these insects by former workers (Fletcher, 1921 & Ramakrishna Ayyar, 1940) but the exact nature of attack has not been clearly indicated. An account of the insects noted and their characteristic features are given here.

Plant introduction as one of the direct methods by which crop improvement can be effected is well recognized. By introducing exotic plants from areas with similar ecological conditions into suitable tracts and acclimatising and exploiting them for exten- sive cultivation, quicker results are obtained. This aspect of crop improvement came to be recognised by the Government of Madras as early as the latter part of 19th Century and the work was carried out at the Government Botanical Gardens, Ootacamund, Sim's Park, Coonoor, gardens at Kalhatti and the fruit stations at Kallar and Burliar. The results of these Plant. Introduction trials on the Nilgiris have been well brought out by Krishnamurthi (1953). All these stations which are situated on the Nilgiris at elevations ranging from 1500 to 7500 ft. enjoy diverse climatic conditions tempered by the altitude and the monsoon rains received during the different seasons of the year. The acclimatisation and extensive cultivation of potato, most of the exotic vegetables, Cinchona, sub-tropical fruits, spices like cloves, nutmeg, all-spice, Cinnamon etc., and the nearly hundred species of Eucalyptus are the results of such Plant Introductions.
A New Method of Planting Sugarcane
Authors:   Chief Sugarcane Officer, Vadapathimangalam, S.V PARTHASARATHY
Published: November 2023

In the south Madras, the monsoon is active from July to November with occasional showers upto mid January, the heaviest rain fall being in October and November months. In lighter sandy soils, preparatory operations like deep ploughing could be carried on with some difficulty by the end of January and February. In heavy soils, particularly in the eastern Tanjore delta, the soil is too wet and it is not ready for any ploughing operations till late in February or March. The delay is greater, particularly when the fields are surrounded by swamp paddy crop varieties like late 'samba', which come for harvest by February-March. Planting of sugarcane under such soil conditions is generally not possible till March or April.
Seepage Irrigation to Sugarcane-A new technique for higher efficiency irrigation in summer

Sugarcane in Madras and Andhra States is subject to drought in summer and water-logging by North East Monsoon, particularly so when it is cultivated in the wet lands of delta region. The main canals of project areas are closed for annual repairs for varying periods from February to June. The subsoil water level goes low and pumping becomes difficult and costly. The soil and atmosphere go dry and losses due to seepage or evaporation in transmitting pumped water are very high. The crops suffer by severe drought in soil and air with consequent reduction in yield and quality of juice.
