This study aims to analyze the influence of regional financial factors consisting of independence and regional wealth on the performance of local governments in Indonesia. This study used secondary data from authorized government institutions with a final sample of 506 local governments which were analyzed using multiple linear regression methods. The results of the analysis show that in terms of achievements, the average performance of local governments in Indonesia has been good, but there are still issues of disparities between regions that need to be corrected.
Meanwhile, the analysis of hypothesis testing through multiple linear regression found a positive effect of regional independence variables on local government performance. Meanwhile, the regional wealth has no significant effect on local government performance. This research has the implication that improving the quality of regional financial management is very important in the implementation of regional autonomy in Indonesia in order to support the achievement of regional performance so that it must be optimized. In this case, the regional government and the central government must synergize through various policies to improve the quality of regional financial management in order to increase independence, fiscal capacity, and optimize assets

Several LaNi5-based hydrogen storage alloys were studied using secondary ion mass spectrometry (SIMS) technique. Ar+ ions with the energy of 10 - 18 keV were used as primary ions. The study of the initial stages of the processes of LaNi5-based alloys interaction with hydrogen under the experimental conditions showed that on the areas of clean surface, hydrogen formed chemical compounds with the both of the main components of the alloy: nickel and lanthanum. As hydrogen accumulates on the surface and in the near-surface region, a hydrogen-containing structure is formed, which is characterized by a certain stoichiometric ratio of components. Nickel in this structure has strong chemical bonds with two hydrogen atoms, and lanthanum – with two or more hydrogen atoms. Along with such compounds, some structures with lower hydrogen content are also formed. The formed hydrogen-containing structure includes both main alloy components, La and Ni for all the studied samples, even though only lanthanum is generally accepted to be the hydride-forming element in such alloys. The SIMS studies of the chemical composition of the surface monolayers of the intermetallic alloy LaNi5, in the process of its interaction with oxygen, showed the following. As a result of the oxygen interaction with the alloy, a complex chemical structure including oxygen, lanthanum and nickel is formed on the surface and in the near-surface region of LaNi5. Oxygen in such a structure, similarly to hydrogen, forms strong chemical bonds with both components of the alloy. This is indicated by the presence in the mass spectra of a large set of oxygen-containing emissions of positive and negative secondary ions with lanthanum and nickel, as well as oxygen-containing lanthanum-nickel cluster secondary ions. The formed oxide compounds have a three-dimensional structure and occupy tens of monolayers. Oxygen poisoning of the surface of the hydride-forming alloy LaNi5 can occur regardless of whether the surface of the alloy was clean from the very beginning or it was covered with a layer of hydrogen-containing chemical compounds.

The paper determines the technological regimes for obtaining GexSi1-x alloys by introducing germanium atoms into single-crystal silicon by the diffusion method. From the results of the study, it was found that the fundamental parameters of the formed GexSi1-x alloys differ from the fundamental parameters of the original silicon, in particular, the energy values of the silicon band gap change. Elemental analysis of the surface of the samples showed that the concentration of silicon (in atomic percent) was ~70.66%, germanium ~29.36%. It was assumed that on the silicon surface and in the front part, a thin layer of an alloy of a compound with a composition of approximately Ge0.3Si0.7 (0.5÷2 μm) would be formed. Analysis of the spectra (p shows that the spectrum contains peaks ~303 cm-1 and ~406 cm-1, corresponding to the Ge-Ge and Si-Ge bonds, respectively. It was also shown that GexSi1-x binary compounds are a new material for modern electronics, the possibility of creating properties on their basis in electronics was shown. It is proposed on their basis to create devices with new functionality and highly efficient solar cells.
Citation Practices in Colombian Undergraduate English Teachers’ Academic Writing
Authors: Salazar Obeso Wilmar 
Published: October 2023

Citation is a crucial rhetorical aspect that plays a fundamental role within academic writing and it is a problematic area for novice writers, especially nonnative undergraduate English teachers. However, little is known about how these teachers cite in the theoretical framework chapters of their monograph. This articles aims at describing the citation practices in a corpus conformed by 22 theoretical framework chapters of monographs written by undergraduate English teachers (UETs) in Colombia. The analysis was constituted by the citation typology of Swales (1986,1990) and Petriḉ’s (2007) functional taxonomy of citations. The results indicate that integral citation is the most used citation type in the corpus of UETs which depicts a simple for of citation. Related to functions, the attribution is highly dominant in this corpus which entails an undergraduate English teachers’ limitation in the variety of function citation. This study can be used to raise awareness on nonnative undergraduate English teachers towards better citation practices in their disciplinary academic papers.

Published: October 2023

Hash-based signatures are one of the most promising classes of cryptographic schemes considered quantum resistant ones. The strength of cryptographic hash functions is one of the most important aspects of ensuring the security of hash-based schemes.
Since classical hash-based signatures require tracking the number of signatures used, they were considered to be stateful for a long time. The SPHINCS scheme overcome this limitation, subsequently refined to SPHINCS+.
The paper provides an assessment of the security of ES based on hash functions relative to side channel attacks.It also gives an analysis of recommendations for the use of one of the candidates of the NIST competition, based on hash cryptography - SPHINCS+, and conclusions about the feasibility of its use.

Abstract
This article explores the development of Beirut's innovation ecosystem in the context of its social composition, complementing popular narratives of informal power in Lebanon. Drawing on ethnographic research, this article explores the extensions of existing institutions and practices—how universities, banks, and diaspora returnees collaboratively developed a context for venture development. By focusing on diaspora returnee expertise as a key driver for innovation ecosystem founding, the article also qualifies a key element of Lebanese economic development—the loops of emigration and return immigration of Lebanese people and the resulting economic and managerial cosmopolitanism inherent in their involvement in their country's commercial and financial settings. The emergent innovation ecosystem is a function of existing Lebanese cultural and organisational tendencies.

Authors: Kin Danylo 
Published: October 2023

The current level of development of geoinformation technologies makes it possible to determine the cartometric properties of terrain objects with a user-defined accuracy. The author of this paper proposes a mathematical model that allows to implement the function of converting geodetic coordinates into rectangular flat Gauss-Kruger projections in a software environment based on the setting of the parameter of the number of members in the Taylor series, adjusting the accuracy of the coordinate transformation and their dimension. The purpose of this work is to implement a mathematical model of a numerical approximate computer method of converting geodetic coordinates into flat rectangular Gauss-Kruger projections. The results of this study will also be used to create functions for converting coordinates from rectangular flat Gauss-Kruger projections to geodetic coordinates and from one 6-degree zone of the Gauss-Kruger projection to another, taking into account the parameter of the number of members in the Taylor series. The proposed mathematical models are recommended to be implemented in the MATLAB or PhyCharm using the necessary libraries. The following studies will focus on determining the areas and lengths of objects located in two or more 6-degree zones of the Gauss-Kruger projection.

Published: October 2023

The article considers the description of the methods of integral assessment of the effectiveness of designing energy-efficient ecological settlements (hereinafter - EES) in the urban planning system, which allows to determine the potential opportunities of the territory for the formation and development of these urban planning entities. The conducted analysis will make it possible to identify "bottlenecks" in the development of territorial communities for the organization of energy-efficient ecological settlements, to develop practical recommendations for increasing the efficiency of designing energy-efficient ecological settlements, based on the existing potential of the territory.
As a result of the conducted research, a unified structural model of EES design was developed. The model consists of four stages, each of which defines structural elements and their relationships. A total of four stages of the model are defined. The first stage is the characterization of the territory. The territory characterization stage is one of the key stages in the system of designing ecological energy-efficient settlements. This stage involves research and data collection on the territory that will be used for the design of the ecological settlement.
The main goal of this stage is to determine the potential of the territory, as well as its limitations and problems that may arise during the implementation of the project. The main stages of territory characterization in the system of designing ecological energy-efficient settlements are defined as follows. Analysis of the topography of the territory: at this stage, the relief, hydrography, geological features of the territory and other factors that affect the natural environment are studied. Study of climatic conditions: the climatic regime of the territory is determined, which may include temperature, precipitation, seasonal changes, wind regime and other parameters. Soil research: at this stage, the structure, composition and quality of soils are studied, which are an important factor for the design of buildings and other engineering systems. Study of the flora and fauna: at this stage, the flora and fauna of the territory are studied, determining their diversity and level of protection. Assessment of the resource potential of the territory: at this stage, the analysis of the economic and social potential of the territory, including information on resources, is carried out.
For the analysis of the territories, the characteristics of sustainable development were determined as elements for the formation of the evaluation system. At the next stage, the efficiency factors of EES design were determined, which were formed into evaluation blocks: ecological, social, economic, geographical, technical, energy-saving. Based on the analysis, a system of indicators was formed, which became the basis for the formation of the evaluation model.
