Pekerjaan perlindungan lereng adalah salah satu pekerjaan yang umum ditemui dalam proyek konstruksi, terutama proyek-proyek infrastruktur, salah satunya adalah Proyek Pembangunan Bendungan Leuwikeris, Ciamis, Jawa Barat. Pada proyek tersebut, pengamanan lereng dilakukan dengan menggunakan shotcrete, namun pada praktiknya, ada beberapa lereng yang terdiri dari tanah yang rawan longsor sehingga penggunaan shotcrete tidak dianjurkan. Pada akhirnya, digunakan lah metode Erotion Control, menggantikan metode shotcrete untuk perlindungan lereng pada lereng yang rawan longsor. Metode Erotion Control ini ternyata membutuhkan waktu yang lebih singkat daripada shotcrete yaitu 228,21 m2/hari untuk erotion control dan 132,88 m2/hari untuk metode Shotcrete. Biaya untuk metode erotion control memang lebih besar daripada metode shotcrete, namun disisi lain, memberikan nilai keuntungan yang lebih besar untuk perusahaan. Kata kunci: Perlindungan lereng, Bendungan Leuwikeris, Shotcrete, Erotion Control, Biaya Abstract [Cost and Time Comparative Analysis of Construction of the Leuwikeris Ciamis Dam with Slope Protection Methods ] Slope protection work is one of the jobs commonly encountered in construction projects, especially infrastructure projects, one of which is the Leuwikeris Dam Development Project, Ciamis, West Java. In this project, slope protection was carried out using shotcrete, however in practice, there are several slopes consisting of lands that are prone to landslides so the use of shotcrete is not recommended. In the end, the Erotion Control method was used, replacing the shotcrete method for slope protection on landslide prone slopes. This Erotion Control method needs a shorter time than the shotcrete method, namely 228.21 m2/day for erotion control and 132.88 m2/day for shotcrete method. The cost for the erotion control method is greater than the shotcrete method, but on the other hand, it provides a greater profit for the company.

Biological variation of serum neopterin concentrations in apparently healthy individuals
Authors: Dülgeroğlu Yakup , Ercan Müjgan 
Published: October 2023

Abstract

Objectives
The aims of this study were to determine the biological variation (BV), reference change value (RCV), index of individuality (II), and quality specifications for serum neopterin concentrations; a measurand provided by clinical laboratories as an indicator of cellular immunity.

Methods
The study delivered serum samples collected for 10 consecutive weeks from 12 apparently healthy individuals (3 male, 9 female). Serum neopterin concentrations were measured using high-performance liquid chromatography with fluorometric detection. The data analysis was performed using an online statistical tool and addressed published criteria for estimation of biological variation.

Results
The mean neopterin concentration was 5.26 nmol/L. The within-subject biological variation (CVI) with 95 % confidence interval (CI) of neopterin serum concentrations was 11.54 % (9.98–13.59), and the between-subject biological variation (CVG) with 95 % CI was 43.27 % (30.52–73.67). The neopterin asymmetrical RCV was −24.9 %/+33.1 %, and the II was 0.27. The desirable quality specifications for neopterin were <5.77 % for precision, <11.20 % for bias, and <20.72 % for total allowable error (TEa). When analytical variation was used instead of CVI to calculate TEa, the desirable TEa was <18.39.

Conclusions
This study determined BV data for neopterin, an indicator of cell-mediated immune response. Asymmetric RCV values, of 24.9 % decrease or a 33.1 % increase between consecutive measurements indicate significant change. The II of 0.27 indicates a high degree of individuality, therefore that it is appropriate to consider the use of personal reference data and significance of change rather than the reference interval as points of reference for the evaluation of neopterin serum concentrations.
Трудности в реализации новой энергетической стратегии России и перспективы китайско-российского энергетического сотрудничества
Authors: Zhao Xin 
Published: October 2023

Аннотация
Энергопереход, сланцевая революция, а также западные санкции против России – все это оказало глубокое влияние на развитие энергетики России. Исходя из принятой Энергетической стратегии до 2035 г. можно предположить, что Россия пока не может избавиться от зависимости от традиционных источников энергии, несмотря на понимание необходимости энергоперехода. В краткосрочной перспективе в условиях современной мировой экономической ситуации, где все еще доминируют традиционные источники энергии, Россия может использовать энергетические рычаги, чтобы отстаивать свою позицию на международной арене. Но в долгосрочной перспективе, если Россия будет отставать в плане энергоперехода, ее экономика может сильно пострадать и ее международное влияние будет ослабевать. Углубление китайско-российского энергетического сотрудничества имеет большое значение для поддержания баланса мировой энергетической системы и содействия устойчивому и здоровому экономическому развитию обеих стран.
Investigating the psychological reality of argument structure constructions and N1 of N2 constructions: a comparison between L1 and L2 speakers of English
Authors: Liu Yingying , McManus Kevin 
Published: October 2023

Abstract
This study examined L1 and L2 English speakers’ sensitivity to constructional meaning by investigating their categorization of Noun1 of Noun2 constructions (e.g., results of studies) and argument structure constructions (e.g., Tom cut the bread). Participants were 40 L1 English speakers and 44 intermediate proficiency Chinese-speaking learners of L2 English, who completed two online sorting experiments. In each experiment, participants were instructed to (i) sort the stimuli according to their overall meaning and (ii) provide explanations for their sorting decisions. Results showed that EFL users preferred construction-based sorting for the argument structure stimuli but not the Noun1 of Noun2 stimuli. However, L1 English speakers showed a preference toward word-based sorting for both construction types. Participants’ self-reported explanations for their sorts nonetheless indicated sensitivity to the constructional meanings of argument structure constructions and Noun1 of Noun2 constructions. Additionally, language users were found more likely to produce construction-based sorts with more time spent on the task.

Simultaneous bioenergy production and dairy wastewater treatment by microbial fuel cell using Taguchi method: performance & optimization study
Authors: Kachroo Himanshu , Shankar Ravi , Mondal Prasenjit 
Published: October 2023

Abstract
Microbial fuel cell (MFC) employs microbial communities as biocatalysts to convert chemical energy from organic substrates to electrical energy. The investigation of MFC incorporated with anaerobic mixed cultures and sulfonated polystyrene (SPS) membrane is of interest for this research due to its competency in generating renewable biological energy and wastewater treatment. Methylene blue was an effective redox mediator in this study. The reactor optimization was performed via the Design of Experiments (DOE) approach using Minitab software. The performance of the batch reactor was optimal with the operating conditions of temperature 30 °C, pH 7, and mediator concentration 250 μM. The contour plots and ANOVA specified that mediator concentration was the most influential parameter that affects MFC performance. MFC fed with 250 μM methylene blue concentration generated a maximum voltage of 0.33 V, current (density) of 4.08 A/m2, power (density) of 1.34 W/m2. The COD removal was 82.4 % at the end of the batch cycle of seven days. The data obtained from the experiments showed that small amounts of a mediator (250 μM) in wastewater elevate the bio-electricity output of the MFC reactor by 1.22 folds.
On the number of limit cycles coming from a uniform isochronous center with continuous and discontinuous quartic perturbations
Authors: Rezaiki Nabil , Boulfoul Amel 
Published: October 2023

Abstract
In this paper, we study the number of limit cycles bifurcated from the periodic orbits of a cubic uniform isochronous center with continuous and discontinuous quartic polynomial perturbations. Using the averaging theory of first order for continuous and discontinuous differential systems and comparing the obtained results, we show that the discontinuous systems have at least 6 more limit cycles than the continuous ones. This study needs some computations that have been verified using Maple.
2D score-based estimation of heterogeneous treatment effects
Authors: Ye Steven Siwei , Chen Yanzhen , Padilla Oscar Hernan Madrid 
Published: October 2023

Abstract
Statisticians show growing interest in estimating and analyzing heterogeneity in causal effects in observational studies. However, there usually exists a trade-off between accuracy and interpretability for developing a desirable estimator for treatment effects, especially in the case when there are a large number of features in estimation. To make efforts to address the issue, we propose a score-based framework for estimating the conditional average treatment effect (CATE) function in this article. The framework integrates two components: (i) leverage the joint use of propensity and prognostic scores in a matching algorithm to obtain a proxy of the heterogeneous treatment effects for each observation and (ii) utilize nonparametric regression trees to construct an estimator for the CATE function conditioning on the two scores. The method naturally stratifies treatment effects into subgroups over a 2d grid whose axis are the propensity and prognostic scores. We conduct benchmark experiments on multiple simulated data and demonstrate clear advantages of the proposed estimator over state-of-the-art methods. We also evaluate empirical performance in real-life settings, using two observational data from a clinical trial and a complex social survey, and interpret policy implications following the numerical results.
Direct numerical algorithm for calculating the heat flux at an inaccessible boundary
Authors: Sorokin Sergey B. 
Published: October 2023

Abstract
A fast numerical algorithm for solving the Cauchy problem for elliptic equations with variable coefficients in standard calculation domains (rectangles, circles, or rings) is proposed.
The algorithm is designed to calculate the heat flux at the inaccessible boundary.
It is based on the separation of variables method.
This approach employs a finite difference approximation and allows obtaining a solution to a discrete problem in arithmetic operations of the order of

N
⁢

ln
⁡

, where 𝑁 is the number of grid points.
As a rule, iterative procedures are needed to solve the Cauchy problem for elliptic equations.
The currently available direct algorithms for solving the Cauchy problem have been developed only for (Laplace, Helmholtz) operators with constant coefficients and for use of analytical solutions for problems with such operators.
A novel feature of the results of the present paper is that the direct algorithm can be used for an elliptic operator with variable coefficients (of a special form).
It is important that in this case no analytical solution to the problem can be obtained.
The algorithm significantly increases the range of problems that can be solved.
It can be used to create devices for determining in real time heat fluxes on the parts of inhomogeneous constructions that cannot be measured.
For example, to determine the heat flux on the inner radius of a pipe made of different materials.
Extract the information via multiple repeated observations under randomly distributed noise
Authors: Zhong Min , Li Xinyan , Liu Xiaoman 
Published: October 2023

Abstract
Extracting the useful information has been used almost everywhere in many fields of mathematics and applied mathematics.
It is a classical ill-posed problem due to the unstable dependence of approximations on small perturbation of the data.
The traditional regularization methods depend on the choice of the regularization parameter, which are closely related to an available accurate upper bound of noise level; thus it is not appropriate for the randomly distributed noise with big or unknown variance.
In this paper, a purely data driven statistical regularization method is proposed, effectively extracting the information from randomly noisy observations.
