Fungsi pengawas pemilu yang dijabarkan dalam tugas,wewenang dan kewajiban pengawas pemilu. Salah satu tugas badan Pengawas Pemilu adalah mengawasi netralitas aparatur sipil negara dalam Pemilu Kepala Daerah. Fenomena pelanggaran pemilu di Kota Pontianak yaitu adanya keterlibatan Aparatur Sipil Negara (ASN) dalam pelaksanaan pemilu. Tujuan penelitian ini untuk mengetahui peran Bawaslu Kota Pontianak dalam menjaga netralitas ASN pada pemilukada. Metode penelitian ini menggunakan metode kualitatif dengan pendekatan deskriptif. Hasil penelitian menujukan bahwa ASN harus memposisikan diri secara netral atau tidak memihak, yang mana kapasitas ASN itu hanya sebagai sebagai pemilih, bukan sebagai pihak yang ikut terlibat secara langsung, baik sebagai tim pendukung salah satu kandidat, maupun dukungan terhadap partai politik tertentu. Bawaslu berupaya membuat panduan pengawasan media sosial, hal ini dilakukan Badan Pengawas Pemilu (Bawaslu) agar dapat secara maksimal menjalankan mandat yang diberikan undang-undang untuk meningkatkan partisipasi masyarakat dalam upaya mencegah pelanggaran Pemilu dan sengketa proses Pemilu. Menurut Bawaslu Kota Pontianak permasalahan netralitas ASN tentunya menjadi salah satu perhatian agar tetap menjaga kode etik Aparatur Sipil Negara.
Konsep Percaya Diri Perspektif Al-Qur'an

A phenomenon that often occurs among the general public and students in particular, namely a lack of confidence in oneself often undermines the soul caused by a lack of knowledge about religion, we often see in schools students who attend school drive cars or motorbikes, they are more confident than those who use bicycles and those who take public transportation. More expensive shoes, changing bags are often a measure for students that can affect their self-confidence. From this research it can be understood that self-confidence in the Qur'an has its starting point from the noble conception of human beings, namely as the Khalifah of Allah, the best of creatures and creatures with free will. The concept of self-confidence in the Qur'an begins with having a clear self-concept of physical characteristics, traits, hobbies, strengths, weaknesses and knowing the obligations that must be carried out according to position. Then, after having a clear self-concept that the individual is a Muslim who has unique physical characteristics, traits and characteristics he must; Think positively about yourself, the situation and the environment around you. After that, every human being must believe that he has the potential given by Allah as the best chosen creature that He has created. This belief, it is not enough if only belief without action proves all of that, but is proven by action (faith and charity).

This study examines the quality management of the Dalwa Syariah hotel which is still under the auspices of Pondok Darullugah Wadd'awah. This study is important because so far speaking of quality, it seems that Islamic boarding schools are still lacking in implementation. Moreover, not many Islamic boarding schools have hotels. So the quality is still questionable. This assumption is not entirely true, Hotel Dalwa Syariah implements quality management that is sourced from the values of the Dalwa. The quality management practiced at the Dalwa Syariah hotel are: in accordance with sharia principles, sincere in serving customers, prioritizing blessings and continuous improvement.
Legal Analysis of Storing Cutlery From Gold and Silver Perspective of the Syafi'i Opinion
Authors: Saefudin
Published: August 2023

The use of gold and silver in cutlery and containers has become a symbol of social status and wealth in various societies, including in Roman times, Europe, America and the Archipelago. This research is a type of library research, which involves reading, studying and analyzing various relevant literature. keeping containers of gold and silver is haram, and can be understood as a step taken to avoid the potential for excessive use, waste of property, or even the impression of arrogance that can arise from the use of these luxury items. However, al Imrani argued that there was no prohibition against keeping containers or cutlery made of gold. According to him, keeping valuable cutlery, such as those made of gold and silver, is permitted because it has economic value which can assist in the development of one's wealth. In the Ushul Fiqh Science Discipline, the prohibition of the use of storing containers made of gold and silver is carried out using the sadd al-żari'ah approach, namely deciding the path of damage. Imam Ibn al-Qasim outlines his views on the use of vessels involving gold or silver coating. According to him, if a vessel contains a layer of gold or silver and if the vessel is placed at a high temperature so that the gold or silver coating melts or disappears, then the use of such a vessel is considered haram.
Keummian Nabi Muhammad dalam Periwayatan Hadis Qudsi
Authors: Elenia Stevani
Published: August 2023

Hadith qudsi is one type of revelation conveyed by Allah and includes the type of khafi/dharuri revelation. In its transmission, the hadith qudsi was verbalized by the Prophet Muhammad, in contrast to the Qur'an, which must be conveyed according to what was received. Hadith qudsi is different from hadith in general because the hadith qudsi is based on Allah. This is because the messages contained in the hadith qudsi contain Allah's sciences which were previously unknown to humans, then conveyed to the Prophet as an explanation of the Qur'an as well as dharuriyat sciences. As Nabiyyi> al-ummiyyi (the deaf illiterate Prophet), the question will arise about the process of transmission from Gabriel to the Prophet Muhammad. Therefore an analysis was carried out using the Library Research method, to answer this problem. With this method, three ways can be found that the Prophet used in narrating hadith qudsi, namely through the intermediary of Jibril by memorizing all the messages conveyed by Gabriel, then understanding with all his intelligence (fatanah). In addition, Jibril also breathed knowledge into the heart of the Prophet, so in this case the Prophet narrated knowledge according to his own meaning which had been guaranteed by Allah to be true.
Epistemologi Perkembangan Tafsir Era Sahabat

Published: August 2023

The development of interpretations needs to be observed as a scientific treasure, including the development of the interpretations of the Companions period which became the embryos of the development of the interpretations of the Koran after the time of the Prophet. Therefore, it is important to know how the development of interpretation at the time of the Companions. This paper uses a descriptive analysis method with a qualitative approach and applies library research types. The result is that the exegesis of the Companions period does not yet have special works like those of the later era, so the exegesis is still scattered randomly like hadith. Interpretations of friends also experience differences, but tend to be more diverse. There are three sources used by friends: the Koran, Hadith, and Ijtihad. The ijtihad techniques of the companions varied according to their scientific capacity. In addition, the interpretation of the Companions is considered to be the authoritative interpretation after the Qur'an and Hadith, because the Companions really understand the history of the revelation of the verses. The quality of the history of the interpretation of the Companions also needs to be analyzed for its status, but there are also many credible paths of transmission.

In an Islamic perspective, morals have an important role in living life. The morals possessed by a child are a form of habit seen from their immediate environment, namely the family. Moral education for children requires good methods, in order to facilitate educators in educating and forming good children's morals. Imam Al-Ghazali and Abdullah Nashih 'Ulwan are some of the Islamic figures who contributed ideas regarding methods of moral education. This study writes about how the method of moral education in children in the perspective of Imam Al-Ghazali and the perspective of Abdullah Nashih 'Ulwan and how is the method of moral education in children compared in the perspective of both? By using a comparative descriptive method, this literature research concludes that there are similarities in the thoughts of Imam Al-Ghazali and Abdullah Nashih 'Ulwan regarding methods of moral education, namely methods of exemplary, habituation, advice, punishment and rewards. Apart from having points of similarity, the two figures also have different points of view regarding the method of moral education in its application and in its concept.

Del autoritarismo a la democracia
Authors: Linz Juan
Published: August 2023

El tránsito a la democracia es uno de los objetivos compartidos por la comunidad internacional con respecto a los regímenes autoritarios. Sin embargo, el conocimiento de la evolución, la velocidad del proceso y sus complejidades, es relativamente escaso, y a menudo las conclusiones a que llegan los analistas son contradictorias. Este artículo aborda los sucesivos problemas que se enfrentan en el trayecto hacia la democratización o redemocratización. El autor intenta responder interrogantes relacionadas con la sucesión y legitimidad de los grupos que deben garantizar la transición. Se refiere también al rol de los militares durante la transición y en la etapa posterior, así como al papel que debe jugar la oposición para que la democracia logre consolidarse. Las conclusiones y recomendaciones que se extraen del trabajo de Linz pueden ser polémicas, pero no cabe duda de que son una valiosa contribución al estudio del tema, y de gran interés para el debate político nacional.

The Breakthrough Listen Initiative is conducting a program using multiple telescopes around the world to search for “technosignatures”: artificial transmitters of extraterrestrial origin from beyond our solar system. The Very Energetic Radiation Imaging Telescope Array System (VERITAS) Collaboration joined this program in 2018 and provides the capability to search for one particular technosignature: optical pulses of a few nanoseconds in duration detectable over interstellar distances. We report here on the analysis and results of dedicated VERITAS observations of Breakthrough Listen targets conducted in 2019 and 2020 and of archival VERITAS data collected since 2012. Thirty hours of dedicated observations of 136 targets and 249 archival observations of 140 targets were analyzed and did not reveal any signals consistent with a technosignature. The results are used to place limits on the fraction of stars hosting transmitting civilizations. We also discuss the minimum pulse sensitivity of our observations and present VERITAS observations of CALIOP: a space-based pulsed laser on board the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations. The detection of these pulses with VERITAS, using the analysis techniques developed for our technosignature search, allows a test of our analysis efficiency and serves as an important proof of principle.
Constraints on Evolutionary Timescales for M Dwarf Planets from Dynamical Stability Arguments
Authors: Teixeira Katie , Ballard Sarah
Published: August 2023

The diversity of dynamical conditions among exoplanets is now well established. Yet, the relevance of orbital dynamical timescales to biological evolutionary timescales is poorly understood. Given that even minor orbital changes may place significant pressure on any organisms living on a planet, dynamical sculpting has important implications for the putative evolution of life. In this manuscript, we employ a Monte Carlo framework to investigate how a range of exoplanetary dynamical sculpting timescales affects timescales for biological evolution. We proceed with minimal assumptions for how dynamical sculpting proceeds and the emergence and persistence of life. We focus our investigation on M dwarf stars, the most common exoplanetary hosts in the Milky Way. We assign dynamical statuses, dependent on stellar age, to a suite of planetary systems, varying the rate of dynamical disruption within limits that are consistent with present-day planet demographics. We then simulate the observed yield of planets according to the completeness of NASA's Kepler and TESS missions, and investigate the properties of these samples. With this simplified approach, we find that systems hosting multiple transiting planets ought to have, on average, shorter dynamically uninterrupted intervals than single-transiting systems. However, depending upon the rate of dynamical sculpting, planets orbiting older stars will exhibit the opposite trend. Even modest constraints on stellar age would help identify older stars for which this holds. The degree of these effects varies, dependent upon both the intrinsic dynamical demographics of exoplanets and whether we consider planets detected by NASA’s Kepler or TESS missions.
Theory and Transport of Nearly Incompressible Magnetohydrodynamic Turbulence: High Plasma Beta Regime

Nearly incompressible magnetohydrodynamic (NI MHD) theory for β ∼ 1 (or β ≪ 1) plasma has been developed and applied to the study of solar wind turbulence. The leading-order term in β ∼ 1 or β ≪ 1 plasma describes the majority of 2D turbulence, while the higher-order term describes the minority of slab turbulence. Here, we develop new NI MHD turbulence transport model equations in the high plasma beta regime. The leading-order term in a β ≫ 1 plasma is fully incompressible and admits both structures (flux ropes or magnetic islands) and slab (Alfvén waves) fluctuations. This paper couples the NI MHD turbulence transport equations with three fluid (proton, electron, and pickup ion) equations, and solves the 1D steady-state equations from 1–75 au. The model is tested against 27 yr of Voyager 2 data, and Ulysses and NH SWAP data. The results agree remarkably well, with some scatter, about the theoretical predictions.

The circumgalactic medium (CGM) plays a crucial role in galaxy evolution as it fuels star formation, retains metals ejected from the galaxies, and hosts gas flows in and out of galaxies. For Milky Way–type and more-massive galaxies, the bulk of the CGM is in hot phases best accessible at X-ray wavelengths. However, our understanding of the CGM remains largely unconstrained due to its tenuous nature. A promising way to probe the CGM is via X-ray absorption studies. Traditional absorption studies utilize bright background quasars, but this method probes the CGM in a pencil beam, and, due to the rarity of bright quasars, the galaxy population available for study is limited. Large-area, high spectral resolution X-ray microcalorimeters offer a new approach to exploring the CGM in emission and absorption. Here, we demonstrate that the cumulative X-ray emission from cosmic X-ray background sources can probe the CGM in absorption. We construct column density maps of major X-ray ions from the Magneticum simulation and build realistic mock images of nine galaxies to explore the detectability of X-ray absorption lines arising from the large-scale CGM. We conclude that the O VII absorption line is detectable around individual massive galaxies at the 3σ–6σ confidence level. For Milky Way–type galaxies, the O VII and O VIII absorption lines are detectable at the ∼ 6σ and ∼ 3σ levels even beyond the virial radius when coadding data from multiple galaxies. This approach complements emission studies, does not require additional exposures, and will allow for probing the baryon budget and the CGM at the largest scales.
Three-dimensional SPH Simulations of FU Orionis Star Flares in the Clumpy Accretion Model
Authors: Demidova Tatiana V. , Grinin Vladimir P.
Published: August 2023

One of the early hypotheses about the origin of FU Orionis star (FUORs) outbursts explains them based on the fall of gas clumps from the remnants of protostellar clouds onto protoplanetary disks surrounding young stars. To calculate the consequences of such an event, we make 3D hydrodynamic simulations using the smoothed particle hydrodynamics method. It is shown that the fall of the clump on the disk in the vicinity of the star actually causes a burst of the star’s accretion activity, resembling in its characteristics the flares of known FUORs. In the region of incidence, an inhomogeneous gas ring is formed, which is inclined relative to the outer disk. During several revolutions around the star, this ring combines with the inner disk and forms a tilted disk. In the process of evolution, the inner disk expands, and its inclination relative to the outer disk decreases. After 100 revolutions, the angle of inclination is a few degrees. This result is of interest in connection with the discovery in recent years of protoplanetary disks, the inner region of which is inclined relative to the outer one. Such structures are usually associated with the existence in the vicinity of a star of a massive body (planet or brown dwarf), whose orbit is inclined relative to the plane of the disk. The results of our modeling indicate the possibility of an alternative explanation for this phenomenon.
Genetic diversity and population structure of the fungus Pseudogymnoascus destructans, the causative agent of white-nose disease: From large scale differentiation to locally homogeneous populations and genetically diverse infections in bats
Authors: Zhelyazkova Violeta , Fischer Nicola , Puechmaille Sebastien
Published: August 2023

White-nose disease (WND), caused by the psychrophilic fungus Pseudogymnoascus destructans, represents one of the greatest threats for North-American hibernating bats. Research on molecular data has significantly advanced our knowledge on various aspects of the disease, yet more studies are needed regarding patterns of P. destructans genetic diversity distribution. In the present study, we investigate three sites within the native range of the fungus in detail: two natural hibernacula (karst caves) in Bulgaria, South-Eastern Europe, and one artificial hibernaculum (disused cellar) in Germany, Northern Europe, that we intensively surveyed between 2014 and 2019. Using 18 microsatellite and two mating type markers, we describe how P. destructans genetic diversity is distributed between and within sites, the latter including differentiation across years and seasons of sampling; across sampling locations within the site; and between bats and hibernaculum walls. We found significant genetic differentiation between hibernacula, but we could not detect any significant differentiation within hibernacula based on the variables examined, which indicates that most of the pathogen’s movement happens within sites. Genotypic richness of P. destructans varied between sites within the same order of magnitude, being approximately two times higher in the natural caves (Bulgaria) in comparison to the disused cellar (Germany). Within all sites, the pathogen’s genotypic richness was higher in samples collected from hibernaculum walls than in samples collected from bats, which corresponds with the hypothesis that hibernacula walls represent the environmental reservoir of the fungus. Multiple pathogen genotypes were commonly isolated from a single bat (i.e., from the same swab sample) in all study sites, which might be an important feature to take into consideration when studying disease progression.
Managing Invasive Wild Boars in Southern Brazil's Protected Areas: Challenges and Strategies
Authors: Etges Matheus , Guadagnin Demétrio L. , Kindel Andreas
Published: August 2023

Invasive species pose significant threats to ecosystems and biodiversity, necessitating effective management strategies to mitigate their impacts. One such invasive species of concern is the wild boar in Brazil, which has the potential to cause widespread environmental changes. A national plan for monitoring and controlling invasive species, including the wild boar, was developed in response to this threat. Despite this initiative, uncertainties persist regarding the presence of wild boars in protected areas (PAs) and the effectiveness of current management actions. This study aimed to diagnose the situation of wild boars in protected areas within the southern region of Brazil, specifically focusing on their distribution, management techniques employed, and reasons for the lack of management action. An online questionnaire was sent to 297 PAs, with 134 responding. The findings revealed that wild boars were present in 39 of the surveyed PAs, but management efforts were only being carried out in 14 of them. Cages and corrals were identified as the most commonly used techniques, with corn serving as the preferred bait. The study identified two primary reasons for the lack of management action: the wild boar's low invasion intensity and management capacity limitations. To address these challenges effectively, the study advocates for a centralized organization of management actions and emphasizes the development of materials and resources to support successful management strategies. Implementing these measures is essential to safeguarding the conservation of ecosystems and vulnerable species in Brazil's protected areas and ensuring the long-term resilience of these valuable ecological assets.
Taxonomic revision and phylogeny of the sharpshooter genus Dasmeusa Melichar, 1926, with a scanning electron microscopy study of D. pauperata (Fabricius, 1803) (Hemiptera: Cicadellidae: Cicadellini)

Published: August 2023

The genus Dasmeusa is distributed in Northern and Northeastern Brazil and the Guianas. Until the present study, six species were recognized within Dasmeusa. The species of this genus are very similar in terms of color and external morphology, being distinguished mainly by the male terminalia. Here, we review and redescribe Dasmeusa and its species, describe four new species, and present the first phylogenetic analysis of the genus, including 40 morphological characters and 15 terminal taxa. Dasmeusa flavescens Metcalf and Erythrogonia bicolor Metcalf are considered junior synonyms of the type-species, Dasmeusa pauperata (Fabricius). Scanning electron microscopy was employed for a detailed study of the integument of the type-species, including sensilla, surface sculpturing, brochosomes, organ of Evans, and other structures. The phylogenetic analysis with equal weights resulted in nine most parsimonious trees. The implied weighting method resulted in two trees, both with the same ingroup topology as observed in one of the nine equal-weights trees. This preferred topology is as follows: ((D. basseti (D. mendica (D. rafaelisp. nov., D. falciferasp. nov.))) (D. isabellina (D. oriximinasp. nov. (D. pauperata (D. imperialis, D. dinizisp. nov.))))). Dasmeusa was recovered as monophyletic in all trees, being supported by five apomorphic characters.

Research on stock price prediction from a data fusion perspective
Authors: Li Aihua , Wei Qinyan , Shi Yong , Liu Zhidong
Published: August 2023

Due to external factors such as political influences, specific events and sentiment information, stock prices exhibit randomness, high volatility and non-linear characteristics, making accurate predictions of future stock prices based solely on historical stock price data difficult. Consequently, data fusion methods have been increasingly applied to stock price prediction to extract comprehensive stock-related information by integrating multi-source heterogeneous stock data and fusing multiple decision results. Although data fusion plays a crucial role in stock price prediction, its application in this field lacks comprehensive and systematic summaries. Therefore, this paper explores the theoretical models used in each level of data fusion (data-level, feature-level and decision-level fusion) to review the development of stock price prediction from a data fusion perspective and provide an overall view. The research indicates that data fusion methods have been widely and effectively used in the field of stock price prediction. Additionally, future directions are proposed. For better performance of data fusion in the field of stock price prediction, future work can broaden the scope of stock-related data types used and explore new algorithms such as natural language processing (NLP) and generative adversarial networks (GAN) for text information processing.

China has built a nationwide transportation network, but there needs to be a smooth connection and transfer between different modes. Five networks are constructed to explore the characteristics of a multimodal comprehensive transportation network (CNet) in Jiangsu Province based on the optimized modeling method and multisource data. Statistical and robustness characteristics are analyzed for CNet and other single-mode networks including the highway, railway, navigation channel and airway networks (HNet, RNet, NNet and ANet, respectively). The research results show following: (ⅰ) In Jiangsu, CNet, HNet, RNet and NNet are not scale-free networks and do not have small-world properties. However, ANet is the opposite. (ⅱ) The five networks in Jiangsu are robust to the random attack and their robustness changes during the attack. However, their robustness is different under different calculated attacks. For all attack strategies, CNet is the most robust. (ⅲ) In Jiangsu, the three optimized methods enhance the robustness significantly. The network failure is delayed by 12.34, 2.79 and 2.44%, respectively. The average connectivity degree is improved by 265.69, 52.95 and 32.54%, respectively. The more hubs there are with powerful transfer capacity, the stronger the network robustness. The results reveal the key points of the construction of a multimodal comprehensive transportation system and can guide the design and optimization of it.

Minimum spanning tree (MST)-based clustering algorithms are widely used to detect clusters with diverse densities and irregular shapes. However, most algorithms require the entire dataset to construct an MST, which leads to significant computational overhead. To alleviate this issue, our proposed algorithm R-MST utilizes representative points instead of all sample points for constructing MST. Additionally, based on the density and nearest neighbor distance, we improved the representative point selection strategy to enhance the uniform distribution of representative points in sparse areas, enabling the algorithm to perform well on datasets with varying densities. Furthermore, traditional methods for eliminating inconsistent edges generally require prior knowledge about the number of clusters, which is not always readily available in practical applications. Therefore, we propose an adaptive method that employs mutual neighbors to identify inconsistent edges and determine the optimal number of clusters automatically. The experimental results indicate that the R-MST algorithm not only improves the efficiency of clustering but also enhances its accuracy.
Sparsity enhanced MRF algorithm for automatic object detection in GPR imagery
Authors: Meng Changpu , Yang Jie
Published: August 2023

This study addressed the problem of automated object detection from ground penetrating radar imaging (GPR), using the concept of sparse representation. The detection task is first formulated as a Markov random field (MRF) process. Then, we propose a novel detection algorithm by introducing the sparsity constraint to the standard MRF model. Specifically, the traditional approach finds it difficult to determine the central target due to the influence of different neighbors from the imaging area. As such, we introduce a domain search algorithm to overcome this issue and increase the accuracy of target detection. Additionally, in the standard MRF model, the Gibbs parameters are empirically predetermined and fixed during the detection process, yet those hyperparameters may have a significant effect on the performance of the detection. Accordingly, in this paper, Gibbs parameters are self-adaptive and fine-tuned using an iterative updating strategy followed the concept of sparse representation. Furthermore, the proposed algorithm has then been proven to have a strong convergence property theoretically. Finally, we verify the proposed method using a real-world dataset, with a set of ground penetrating radar antennas in three different transmitted frequencies (50 MHz, 200 MHz and 300 MHz). Experimental evaluations demonstrate the advantages of utilizing the proposed algorithm to detect objects in ground penetrating radar imagery, in comparison with four traditional detection algorithms.

Aerodynamic Analysis of Supersonic Spikes for Drag Reduction
Authors: Khan Md Akhtar , Vigneshwar K.
Published: August 2023

This research aims to examine the flow field over a NACA 651-412 aerofoil at a supersonic Mach number (M = 2) in the presence of a sharp spike and a Hemi spherical head spike. Using a spike integrated with an aerofoil alters the flow characteristics of the aerofoil, resulting in changes in aerodynamic lift and drag. Flow visualisation graphs and coefficients of aerodynamic drag and lift are measured. In this work, two spike designs were employed: sharp edges and hemispherical edges. The flow over an aerofoil with and without a spike is also compared in order to comprehend the performance of the NACA 6 series aerofoil with different geometry alteration. For computational simulation, ICEM CFD is used as a meshing tool and ANSYS fluent as an adjoint solver to analyse the external flow over the body. Furthermore, the drag increases significantly when the flight angle of attack increases. Employing certain installation angles effectively improves the drag reduction around the angle of attack and improve the lift-to-drag ratio.
