General formulae for the periapsis shift of a quasi-circular orbit in static spherically symmetric spacetimes and the active gravitational mass density

We study the periapsis shift of a quasi-circular orbit in general static spherically symmetric spacetimes. We derive two formulae in full order with respect to the gravitational field, one in terms of the gravitational mass [Formula: see text] and the Einstein tensor and the other in terms of the orbital angular velocity and the Einstein tensor. These formulae reproduce the well-known ones for the forward shift in the Schwarzschild spacetime. In a general case, the shift deviates from that in the vacuum spacetime due to a particular combination of the components of the Einstein tensor at the radius [Formula: see text] of the orbit. The formulae give a backward shift due to the extended-mass effect in Newtonian gravity. In general relativity, in the weak-field and diffuse regime, the active gravitational mass density, [Formula: see text], plays an important role, where [Formula: see text], [Formula: see text] and [Formula: see text] are the energy density, the radial stress and the tangential stress of the matter field, respectively. We show that the shift is backward if [Formula: see text] is beyond a critical value [Formula: see text][Formula: see text]g/cm3[Formula: see text], while a forward shift greater than that in the vacuum spacetime instead implies [Formula: see text], i.e. the violation of the strong energy condition, and thereby provides evidence for dark energy. We obtain new observational constraints on [Formula: see text] in the Solar System and the Galactic Centre.

The Relationship of Parental Control with Children’s Digital Literacy Skills in Pesisir Selatan

The digital divide in Indonesia demands that digital literacy education be delivered through several knowledge transfer mechanisms. The purpose of this research is to look at the relationship between parental control and digital literacy skills in children in Pesisir Selatan. This type of research is quantitative correlational. Sources of data in this study are parents and children. The population in this study amounted to 30 parents and the sampling technique was Simple Random Sampling and 70% were taken, namely 21 children. The data collection method uses a questionnaire with a statement list format as a data collection tool, data analysis techniques use a percentage formula and to find correlations use the Rank Order formula. The results of the study found: 1) Parental control of this child was classified in the unfavorable category. 2) digital literacy skills in children are classified in the low category. 3) There is a significant relationship between parental control and digital literacy skills in children in Pesisir Selatan. Furthermore, some suggestions are: 1) According to the respondents' assessment, parental control over children is still much that has not been implemented, when viewed from the duties and responsibilities of parents, it is suggested to parents to better understand their duties and responsibilities so that they are able to protect children from the dangers of digital media. 2) It is necessary for children to be aware of how important it is to understand increasingly sophisticated digital media that can develop various potentials in children so that they have knowledge and experience. 3) It is hoped that other studies will be able to see several other factors that have not been studied in this study

Gauss diagram formulae for Vassiliev invariants from Kauffman polynomial

A state model for Kauffman polynomial of Dubrovnik-version is described using Gauss diagrams. Based on the state model, the Gauss diagram formulae for Vassiliev invariants are given from the coefficients of Kauffman polynomial following the method of Chmutov and Polyak. Some arrow diagram identities are given to simplify the Gauss diagram formulae of order 3, which give Polyak–Viro and Chmutov–Polyak formulae for the Vassiliev invariant of order 3. The models of Kauffman polynomial and HOMFLY-PT polynomial give different Gauss diagram expressions when specializing in Jones polynomial.

Sign balances and promotion order of Young-Fibonacci tableaux

In this paper we give two results on Young Fibonacci tableaux. First we establish identities about the sign balances of Young Fibonacci tableaux, analog to known results on standard Young tableaux. Then we investigate the promotion action on a Young Fibonacci tableau and determine the order of the action. In contrast with the fact that there is no general formula of the promotion order for a standard Young tableau, here we can determine the order completely.

Computing indefinite integrals by difference equations

In teaching mathematics to first-year undergraduates, and thus in the appropriate calculus textbooks, the task of calculating an integral that satisfies a specific first-order or second-order recurrence relation often appears. These relations are obtained mainly by applying the method of integration by parts. Calculating such integrals is usually tedious, especially for an integer n > 2, time-consuming, and presents the possibility of making a large number of errors when computing involves multiple iterative steps. In [1], it is shown that in two cases (Theorems 2.1. and 2.3), the process of calculating integrals satisfying first-order recurrence relations can be performed quickly using easily memorised closed-form formulas for corresponding primitive functions. The question can rightly be asked whether there is a faster way to calculate other integrals of this type. In this paper, our goal is to give an affirmative answer to such a question, though without convering all situations. Since each recurrence relation is equivalent to a difference equation of the same order, the calculation of integrals mentioned above can be reduced to solving the corresponding difference equations. Since every first-order or second-order linear difference equation is solvable, it follows that for every integral which can be reduced to a first- order or second-order recurrence formula, it is possible to find corresponding primitive functions directly. Sometimes such a procedure is much faster than iterative solving of the integral. Closed-form formulas for the integrals discussed in the following sections are not unknown (see [2]). However, here our goal is to present the idea of computing indefinite integrals using difference equations. We will discuss it in more detail in Section 2. In Section 3, we discuss the application of the results obtained to calculate several improper integrals and the application of some of them in different sciences. An exciting example of such an application is the integral , which in the case n = 1 is used in the kinetic theory of gases, particularly in the Maxwell-Boltzmann distribution of gas molecules by energies (see Remark 4). Also, we compare the formulas obtained by the method of difference equations with the formulas obtained using Wolfram Alpha software (see Remark 5).

Effect of breastfeeding on the HMGA2 single nucleotide polymorphisms in relation to first primary tooth emergence among Iraqi infants

Abstract Backgrounds: Breastfeeding provides a large group of functional components that improve the infant’s health and development. additionally, the impact of human milk and genetic variants on complicated outcomes has also been the subject of several gene–nutrition interaction studies. This could also play a key part in the kinship that exists between offspring and their parents. Objectives: The purpose of this study was to compare breastfeeding to infants who were fed formula in order to determine if human milk affected the timing of teething in relation to genetic polymorphisms. Materials and Methods: This study is a cross-sectional comparative study concerning genetic analysis with a prospective view concerning the timing of eruption. The chosen sample included 40 breastfed infants and 40 infants who consumed formula milk. It was compiled from Baghdad’s health centers. For the genetic analysis, DNA samples were obtained from saliva throughout the buccal swab. Standard DNA extraction and real-time PCR techniques have been used according to the manufacturer’s instructions for the Quick-DNA™ MiniPrep kit (catalog nos. D3024 and D3025). For the whole sample, clinical examination and monitoring for emerging teeth were performed using a particular criterion. Results: findings showed that there were highly significant differences between breastfeeding and early eruption time for the first primary tooth. Also, there was a significant association between single nucleotide polymorphisms in the heterozygous AG genotype and eruption time. Conclusion: The results of the current study may support the genetic influence of breast milk on early primary teeth eruption when juxtaposed with infants fed formula.

Human Energy Expenditure in High-Level Order Picking

Order picking is one of the most significant components of the warehouse management. More than 50% of the cost incurred in warehouses is due to the order picking process. Although this process has mostly been considered within the framework of economic objectives, in recent years the ergonomic perspective has become increasingly visible. Order picking studies regarding ergonomic objectives have mostly focused on low-level order picking systems, but the human factor has been ignored in high-level order picking. In order to fill this gap, this study focuses on the order picking process of a single block high-level warehouse with a special focus on human factor. For this purpose, a capacity-constrained mathematical model based on order batching and routing for the minimization of human energy expenditure is proposed. In this three-dimensional (3D) warehouse system, the distances and travel times between locations were first determined using Tchebychev formulas in order to calculate the human energy expenditure between order locations. Then, human energy matrices between order locations were created using human energy calculation formulas based on time and item weight. These matrices, which were created for three different randomly generated sample data sets, were used in the mathematical model solution and the optimum batches and routes were determined. In order to compare the results, First-come First-serve (FCFS) batching and S-shaped routing, which are simple and common batching and routing methods used in practice, were applied for the sample problem data sets and it was observed that the mathematical model gave better results.

Efektivitas Metode Index Card Match Dalam Meningkatkan Pemahaman Belajar Siswa Pada Mata Pelajaran Pendidikan Agama Islam (PAI) Di SMP Tahfidz Qur’an Al-Fatih Bengkalis

The researcher discusses the Index Card Match Method (looking for pairs of cards) which is a fun learning method used to repeat material previously provided. This type of research is field research with a quantitative approach, namely a research method based on the philosophy of positivism. Data collection uses a questionnaire, observation and interviews. After the data was collected, the researcher used the prodact moment formula in order to find out alternative success scores for learning using the index card match method. From the percentage results, the recapitulation of the results of the questionnaire respondents answered the effectiveness of the lecture method in increasing students' learning understanding in Islamic Religious Education (PAI) subjects. has a less good and less high value, because the alternative answers yes are fewer than the alternative no, the percentage result is 44.65. While the research results from the recapitulation of the questionnaire regarding the index card match method in increasing students' learning understanding in the subject of Islamic Religious Education has a value of 89%. This is included in the very good criteria, which means that H0 is rejected, thus the Alternative Hypothesis (Ha) is accepted

An Examination of the Representation of the Autistic Community in Film

Autism spectrum disorder (ASD) is a life-long neurodevelopmental disorder where individuals with a diagnosis have communication challenges and many restrictions within their everyday life. Being a disadvantaged community, they tend to face discrimination and stigmatization on social media associated with social withdrawal and lower mental health. Their representation in film may have similar effects yet rarely studied. This study uses a directed content analysis with codes derived from the DSM-5 test and Baker’s Autistic Formula in order to calculate frequencies, duration, and percentages of movies devoted to each stereotype or criterion. The results from this research reveal that although the film industry is being representative they may be over-using certain symptoms and using stereotypes that the autistic community may find offensive.

RBF based some implicit–explicit finite difference schemes for pricing option under extended jump-diffusion model

In this manuscript, we presented some efficient and accurate radial basis function-based finite difference (RBF-FD) implicit–explicit (IMEX) numerical techniques for pricing the option when the underlying asset follows the jump-diffusion process with local volatility. For the time semi-discretization, we present three numerical techniques Crank–Nikolson Leap-Frog (CNLF), Crank–Nikolson AdamBashforth (CNAB), and Backward difference formula of order two (BDF2), incorporated with the radial basis function based finite difference (RBF-FD) method. The stabilities of time semi-discretized schemes are also proved. The computational methods developed for the European option are extended for the American option. We amalgamate the RBF-FD implicit–explicit methods with an operator splitting (OS) method for solving the linear complementarity problem (LCP) with variable parameters that determines the price of an American option. In order to demonstrate the effectiveness and precision of the current techniques, numerical data for European and American put options under the Merton and Kou models are presented.

A convergent finite element algorithm for mean curvature flow in arbitrary codimension

Optimal-order uniform-in-time H^1 -norm error estimates are given for semi- and full discretizations of mean curvature flow of surfaces in arbitrarily high codimension. The proposed and studied numerical method is based on a parabolic system coupling the surface flow to evolution equations for the mean curvature vector and for the orthogonal projection onto the tangent space. The algorithm uses evolving surface finite elements and linearly implicit backward difference formulas. This numerical method admits a convergence analysis in the case of finite elements of polynomial degree at least 2 and backward difference formulas of orders 2 to 5. Numerical experiments in codimension 2 illustrate and complement our theoretical results.

Euler's Formula-Based Research on the Dynamics of Cycling Competition

Speed and endurance are tested in the sport of road cycling, and competitors must appropriately distribute their physical strength based on the road's conditions. This study establishes a bicycle dynamics model based on the rider's motion state and power limitations, as well as the rider's constant power, using the Euler formula in order to obtain the rider's ideal riding strategy. The road conditions are divided into four categories by creating a three-dimensional space coordinate model of the track: uphill, downhill, sharp turns, and flat ground. The cyclist dynamics model is then meticulously optimized to forecast the best performance of various riders on various tracks. The predicted result is improved by the outcome and the reference power allocation scheme.

Tori over number fields and special values at $s=1$

We define a Weil-étale complex with compact support for duals (in the sense of the Bloch dualizing cycles complex \mathbb{Z}^c ) of a large class of \mathbb{Z} -constructible sheaves on an integral1-dimensional proper arithmetic scheme flat over Spec( \mathbb{Z} ). This complex can be thought of as computing Weil-étale homology. For those Z-constructible sheaves that are moreover tamely ramified, we define an “additive” complex which we think of as the Lie algebra of the dual of the \mathbb{Z} -constructible sheaf. The product of the determinants of the additive and Weil-étale complex is called the fundamental line. We prove a duality theorem which implies that the fundamental line has a natural trivialization, giving a multiplicative Euler characteristic. We attach a natural L -function to the dual of a \mathbb{Z} -constructible sheaf; up to a finite number of factors, this L -function is an Artin L -function at s = 1 . Our main theorem contains a vanishing order formula at s = 0 for the L -function and states that, in the tamely ramified case, the special value at s = 0 is given up to sign by the Euler characteristic. This generalizes the analytic class number formula for the special value at s = 1 of the Dedekind zeta function. In the function field case, this is a theorem of Geisser–Suzuki.

Repetitive Acoustic Streaming Patterns in Sinusoidal Shaped Microchannels

Geometry of the fluid container plays a key role in the shape of acoustic streaming patterns. Inadvertent vortices can be troublesome in some cases, but if treated properly, the problem turns into a very useful parameter in acoustic tweezing or micromixing applications. In this paper, the effects of sinusoidal boundaries of a microchannel on acoustic streaming patterns are studied. The results show that while top and bottom sinusoidal walls are vertically actuated at the resonance frequency of basic hypothetical rectangular microchannel, some repetitive acoustic streaming patterns are recognised in classifiable cases. Such patterns can never be produced in the rectangular geometry with flat boundaries. Relations between geometrical parameters and emerging acoustic streaming patterns lead us to propose formulas in order to predict more cases. Such results and formulations were not trivial at a glance.

Multi-scale soot formation simulation providing detailed particle morphology in a laminar coflow diffusion flame

The macroscopic simulation of soot production in flames by CFD approaches often assumes of spherical particles or considers ad-hoc formulas in order to take the particle fractal aggregates’ morphology into account. On the other hand, numerically simulated aggregates can be generated by Discrete Element Modeling (DEM) simulations at the nanoscopic scale. However, the change in thermodynamic conditions, surface growth, oxidation, and nucleation mechanisms are commonly neglected by this approach. This work combines these complementary approaches to investigate the detailed morphology of soot along 4 different particle trajectories in a diffusion flame. The proposed multi-scale approach shows remarkably larger and more compact aggregates near the wings of the flame as compared to the centerline, in agreement with previous experimental studies. This approach allows to analyse the particle polydispersity and morphological parameters beyond the fractal dimension, such as anisotropy coefficient and monomers overlapping coefficient. It becomes possible to reveal clear morphological signatures of soot formed along different streamlines in the flame. Finally, we have also observed a positive correlation between primary particle diameter and aggregate gyration diameter due to the predominance of surface reactions over aggregation. The proposed post-processing of CFD results based on DEM methods, bringing new information on soot morphology, is a proof of concept of a more accurate procedure for validating soot models used in CFD codes as compared to existing methods in the literature.

Optimization of an inset-fed calculations for rectangular microstrip antenna

This paper offers an alternative solution to produce a formula to calculate the inset-fed (????????) feed distance from the edge of the patch in order to obtain the impedance of a rectangular patch microstrip antenna as close to 50 Ohm as possible. The basic calculation refers to Ramesh's calculation formula to calculate the inset-fed (????????) on a rectangular patch microstrip antenna. From this research it is hoped that a number of correction factors will be obtained which will be multiplied by the Ramesh formula in order to obtain an inset-fed calculation which results in a lower return loss (????????????) and voltage standing wave ratio (VSWR). From several calculation attempts, the approximate value for the correction factor is s=0.83477. This s correction factor is then multiplied by Ramesh's calculation formula. In this experiment, a microstrip antenna was simulated using an FR4 epoxy printed circuit board (PCB) with a relative permittivity, ???????? = ????. ????, with a thickness of h=1.6 mm. The specified antenna nominal input impedance is 50 Ohms. The transmission line used is a microstrip line with a characteristic impedance of 50 Ohm. The test method used is to compare the results of simulation calculations using the Ramesh formula with the results of simulation calculations using the Ramesh formula multiplied by the correction factor. Tests are carried out using varying working frequencies. From the experimental results it can be seen that the average Return Loss (????????????) and VSWR of the antenna are lower when using the Ramesh formula with a correction factor compared to the original Ramesh formula.
