Published: August 2023

••• English ••• Islamic law of the contract is used as the basis for muamalah transaction, which is oriented towards developing a general theory of Islamic law. This research is significant because of the birth of sharia institutions based on the provisions of Islamic contract and muamalah, as well as the growing business of Muslims accompanied by the emergence of a desire to harmonize business as a modern phenomenon, with the sharia principle. The methodology of this reseacrh, including normative Islamic law research, is to obtain concrete legal regulations which are the development of norms between Islamic legal doctrines, which are also derived from basic values in Al-Qur'an and Sunnah. The result is, based on the Islamic contract in Indonesia, several are used as basis in carrying out and forming the Islamic contract law. The purpose of implementing muamalah in philosophy is a contract that upholds socio-economic justice and income/welfare justice which are considered important components of Islamic moral philosophy. Islamic economic philosophy in this regard can be summarized in three aspects namely at-tauhid, al-’adalah, and maslahah, where the source of law is Al-Qur'an and Sunnah. ••• Indonesian ••• Hukum Islam dalam akad digunakan sebagai dasar transaksi muamalah, yang berorientasi pada pengembangan teori umum hukum Islam. Penelitian ini penting karena lahirnya lembaga syariah berdasarkan ketentuan kontrak Islam dan muamalah, serta berkembangnya bisnis umat Islam disertai dengan munculnya keinginan untuk menyelaraskan bisnis sebagai fenomena modern, dengan prinsip syariah. Metodologi dalam penelitian ini termasuk pada penelitian hukum Islam normatif, yakni untuk mendapatkan peraturan hukum yang konkret yang merupakan pengembangan norma-norma antara doktrin hukum Islam, yang juga diturunkan dari nilai-nilai dasar dalam Al-Qur'an dan Sunnah. Hasil yang didapat, berdasarkan akad Islam di Indonesia, beberapa digunakan sebagai dasar dalam menjalankan dan membentuk hukum kontrak Islam. Tujuan pelaksanaan muamalah pada filsafat adalah kontrak yang menjunjung tinggi keadilan sosial ekonomi dan keadilan pendapatan/kesejahteraan yang dianggap sebagai komponen penting dari filsafat moral Islam. Filsafat ekonomi Islam dalam hal ini dapat diringkas dalam tiga aspek yaitu at-tauhid, al-‘adalah, dan maslahah di mana sumber hukumnya adalah Al-Qur'an dan Sunnah.
Panacea to Domestic Gas Supply Accessibility and Affordability in Nigeria
Authors: Ugolo Jerry Obaro , Iwegbu Michael 
Published: August 2023

Abstract
Nigeria with a proven gas resource base of over 206tcf possesses the biggest gas reserve in the continent of Africa and is the 9th largest in the World (NUPRC website, 2021). However, Nigeria faces the challenge of making clean cooking gas accessible and affordable for its populace. Investments in making cooking gas affordable will improve the economy of the average household and reduced carbon footprint in this part of the world.
The Nigerian Government by March 29th, 2021 proclaimed the following decade, the decade of gas reform and development. The blueprint of a Nigerian Gas Master Plan (NGMP) focusing on accelerating the growth of the country's gas sector was to be adopted. Efforts required in this plan would include developing better-adapted technologies and delivery models, and stronger institutional frameworks. Substantial efforts are required across the region to help convert the abundant natural gas resources into adequate domestic gas utilization and hence for national development.
A key factor for making clean gas accessible and affordable for all, is to have in place, gas infrastructure for storage and distribution. A number of Nigerian oil and gas production platforms still flare their gas due to inadequate gas processing, treatment, and storage facilities. Other factors hindering development of the domestic gas sector include the non-adoption of modern gas recovery technology, inadequate media enlightenment, and stakeholders’ willingness to invest in carbon footprint reduction initiatives.
Using quantitative research methodology, the researcher looked at the pricing of Liquified Petroleum Gas (LPG) over a 7-year (2016-2022) period. Examination of the gas infrastructure development within the same period was also analysed to determine if more gas has been made available in the Nigerian market. A survey was done to ascertain possible factors affecting investment in gas sector of Nigeria. Secondary data was obtained from the World bank databases showing revenue generated from gas amongst top 10 African countries. This helped to show value obtained from the gas sector.
Key benefits for making domestic gas accessible and affordable would include, improved Gross Value Addition (GVA) for investors and the national economy, better health conditions for the millions already affected by using solid biomass (firewood and charcoal) for cooking as well as reduction in carbon emissions.

Abstract
The scene of large factories is complex, and the requirements for production safety are higher. At present, complex factories mainly use manual operation mode to carry out safety inspection, that is, manual inspection and manual recording mode to inspect factory equipment, which has the disadvantages of high labor intensity, low work efficiency and unstable inspection quality. In recent years, with the development of robot navigation related technologies, it has provided a new idea for solving autonomous navigation in large-scale and complex factory environment with variable obstacles. Therefore, we design a slam and path planning method based on multi-sensor fusion, including the establishment of complex and large-scale factory maps, dynamic obstacle avoidance and local path planning, which can achieve accurate and efficient autonomous positioning and effectively generate smooth and safe paths. The security, smoothness, flexibility and efficiency of this method are verified in various complex simulation scenarios and challenging real world. It is proved that this method can meet the performance requirements of positioning and path planning in large-scale complex industrial scenes, and has a good application prospect.
CFD-DEM model of plugging in flow with cohesive particles
Authors: Saparbayeva Nazerke , Balakin Boris V. 
Published: August 2023

Abstract
Plugging in flows with cohesive particles is crucial in many industrial and real-life applications such as hemodynamics, water distribution, and petroleum flow assurance. Although probabilistic models for plugging risk estimation are presented in the literature, multiple details of the process remain unclear. In this paper, we present a CFD-DEM model of plugging validated against several experimental benchmarks. Using the simulations, we describe the process focusing on inter-particle collisions and plugging dynamics. We conduct a parametric study altering the Reynolds number (3000...9000), particle concentration (1.6...7.3%), and surface energy (25...541 mJ/m 2). We note the process possesses complex non-linear behaviour for the cases where the particle-wall adhesion reduces by more than 20% relative to the inter-particle cohesion. Finally, we demonstrate how the simulation results match the flow maps based on the third-party experiments.

Abstract
Background: Since the onset of the COVID-19 pandemic, the worldwide prevalence of maternal depression has risen sharply; it is now estimated that one-quarter of mothers experience clinically significant depression symptoms. Exposure to maternal depression during early childhood increases the risk for the development of childhood mental illness (MI) in offspring, with altered parenting practices mediating the association between maternal depression and child outcomes. Dual-generation interventions, which aim to simultaneously treat parent and child mental health, show promise for improving outcomes for mothers with depression and their young children. The Building Regulation in Dual Generations (BRIDGE) program combines Dialectical Behavior Therapy (DBT) and parenting skills training to concurrently treat maternal depression and improve parenting practices. In pilot within-group studies, BRIDGE has led to large reductions in maternal depression and child MI symptoms. The aim of the current study is to evaluate the efficacy of BRIDGE in reducing maternal depression and child MI symptoms (primary outcomes) as well as parenting stress and harsh parenting (secondary outcomes).
Methods: A three-armed randomized control trial with equal group sizes will be conducted to compare the efficacy of (1) BRIDGE (DBT + parenting skills), (2) DBT skills training, and (3) services-as-usual. Participants (n=180) will be mothers of 3- to 5-year-old children who report elevated depression symptoms. Those randomized to BRIDGE or DBT skills training will complete a 16-week group therapy intervention. Assessments will be administered at pre-intervention(T1) post-intervention (T2), and 6-month follow-up (T3).
Discussion: Dual-generation programs offer an innovative approach to prevent the intergenerational transmission of mental illness. The current study will add to the evidence base for BRIDGE by comparing it to a stand-alone mental health intervention and a services-as-usual group. These comparisons will provide valuable information on the relative efficacy of including parenting support in a mental health intervention for parents. Results will contribute to our understanding of how maternal depression affects children’s development, and how intervening at both a mental health and parenting level may affect child and family outcomes.

Fungal spillover influences plant competitive ability and affects species’ coexistence
Authors: Errico Gina , Zhang Bo , Bachelot Benedicte Marie Philippe 
Published: August 2023

Abstract
Tropical forests are the most biodiverse ecosystems in the world and are critical to global ecosystem functions. Anthropogenic activities have increased forest fragmentation, which could introduce new biotic interactions into tropical forests via spillover, yet little is known about how spillover influences tropical tree diversity. Existing spillover theory has mainly focused on transmission dynamics rather than plant species coexistence. We developed a theoretical spatial model consisting of one predator (fungi) interacting with two prey (plant) populations and introduced a new fungal pathogen via diffusion to mimic spillover. We aimed to understand how spillover pathogen host-specificity, spillover intensity, and plant competitive abilities alter plant coexistence outcomes. Results show that spillover, contingent on plant species’ competitive ability, can either promote or disrupt coexistence. While spillover disrupts plant existence at the forest edge, generalist spillover acts as an equalizing mechanism, enabling plants with different competitive abilities to coexist. In contrast, specialized spillover acts as a stabilizing mechanism when targeting the strong plant competitor, eventually reversing plant apparent competitive abilities. These effects are heightened with wind. Our model provides insight on the influences of fungal pathogen spillover on plant community composition and diversity when the effects of fungal spillover in field are unknown.
Unraveling the development and secretory structures of the atypical flowers of Dalea purpurea (Leguminosae: Papilionoideae)
Authors: Martins Santiago Macario , Mansano Vidal de Freitas , Leite Viviane Gonçalves , Paulino Juliana Villela 
Published: August 2023

Abstract
Dalea purpurea, an herbaceous papilionoid legume of the North American Great Plains, has floral characteristics that are highly atypical within subfamily Papilionoideae, such as organs reduction, low differentiation among petals, with keel absence, adnation between petals and stamens and presence of anther glands. This study aims to elucidate the ontogenetic processes responsible for its atypical architecture. Floral buds and flowers were processed by scanning electron microscope (SEM) and light microscope (LM). Five sepals initiate in a modified unidirectional order, followed by five petals simultaneously. The five antesepalous stamens initiate in a bidirectional order. No antepetalous stamens primordia were initiated, suggesting that the presumed evolutionary reduction from ten to five stamens in Dalea was due to ontogenetic pathway organ absence since the initiation. The single and central carpel is precocious, emerges concomitantly with the first stamen primordium. The hypanthium is short, and the ovary is superior, with a short stipe. The five anthers are dorsifixed and rimose, with elongated glandular dorsal and apical appendages. The petals are clawed, and positioned like a hood above the reproductive whorls during development. We found an adnation of the basal region of the filaments to the petal claws, forming a stemonozone. The structure, on the abaxial side, forms an elongated sheath through the adnation of the stamens to four weakly differentiated petals to the height of the calyx lacinia. The adaxial petal (banner) is free for the most part, with adnation only at the base of the stemonozone, forming the apron. The peculiar feature absence of the typical staminal tube seems to be circumvented by the adnation of the five stamens to the five petals and the position of the adaxial petal in D. purpurea, which looks like it performs a similar function to that of the diadelphous staminal tube of other Papilionoideae. The diversity and distribution of floral secretory structures indicate that this species, which lost part of its floral specialization, might be using chemical defenses as protection against the predation of the reproductive organs. Thus, we conclude that the atypical Dalea pupurea’s floral architecture is due to some ontogenetic events associated with evolutionary and environmental pressures.
Simulating AMOC tipping driven by internal climate variability with a rare event algorithm.
Authors: Cini Matteo , Zappa Giuseppe , Ragone Francesco , Corti Susanna 
Published: August 2023

Abstract
This study investigates the possibility of Atlantic Meridional Overturning Circulation (AMOC) noise-induced tipping solely driven by internal climate variability without applying external forcing that alter the radiative forcing or the North Atlantic freshwater budget. We address this hypothesis with an innovative approach by applying a rare event algorithm to ensemble simulations of present-day climate with an intermediate complexity climate model. The algorithm successfully identifies trajectories leading to abrupt AMOC slowdowns, which are unprecedented in a 2000-year control run. Part of these AMOC weakened states lead to collapsed state without evidence of AMOC recovery on multi-centennial time scales. The temperature and Northern Hemisphere jet stream responses to these internally-induced AMOC slowdowns show strong similarities with those found in externally forced AMOC slowdowns in state-of-the-art climate models. The AMOC slowdown seems to be initially driven by Ekman transport due to westerly wind stress anomalies in the North Atlantic and subsequently amplified by a complete collapse of the oceanic convection in the Labrador Sea. These results demonstrate that transitions to a collapsed AMOC state purely due to internal variability in a model simulation of present-day climate are rare but physically possible. Additionally, these results show that rare event algorithms are a tool of valuable and general interest to study tipping points since they introduce the possibility of collecting a large number of tipping events that cannot be sampled using traditional approaches. This opens the possibility of identifying the mechanisms driving tipping events in complex systems in which little a-priori knowledge is available.
Fabrication of automotive titanium bipolar plates by uniform pressure electromagnetic incremental forming based on arc spiral coil

Published: August 2023

Abstract
Facing the forming requirements of large-sized automotive titanium bipolar plates (BPPs), a uniform pressure electromagnetic incremental forming (UP-EMIF) process was utilized. Corresponding simulation and analysis were conducted based on the designed arc spiral coil. Analysis of the magnetic field revealed that during the forming process, electromagnetic forces on the coil wire tended to compress in radial direction, while the electromagnetic forces on the outer channel exhibited repulsive tendencies toward the driver sheet, and the electromagnetic forces on the driver sheet transitioned from a wavy pattern to a uniform distribution. Velocity and equivalent strain analysis showed that the maximum deformation velocity of the blank occurred at the bottom of the channel, reaching 195m/s. The highest equivalent strain of the blank occurred in the rounded corner R region, which was prone to thinning of wall thickness. Based on these findings, UP-EMIF and traditional quasi-static drive rubber pad forming (QS-DRPF) experimental devices were developed, and a comparative study on the forming of 0.1mm thick automotive titanium BPPs was conducted. Research indicated that successful production of a titanium BPP measuring 485mm×195mm was achieved using three consecutive discharges of 9kV in each discharge region under the discharge capacitor of 100μF, an acceleration distance of 2mm, a coil overlap rate of 15%, and a 0.3mm thick Cu110 driver sheet. The depth of the channels was 0.4mm (channel depth-to-width ratio of 0.53). Compared to traditional QS-DRPF, the 9kV UP-EMIF reduced channel thinning effectively, with a maximum thinning rate of 18.2%, while simultaneously improving channel filling, with a maximum filling rate of 96.3%. This demonstrates the feasibility of UP-EMIF as a process for fabricating automotive titanium BPPs.
Metric type-II radio bursts and space weather phenomena: A statistical study
Authors: Devi Pooja , Miteva Rositsa , Chandra Ramesh , Koleva Kostadinka , Lawrance Bendict 
Published: August 2023

Abstract
In this paper, we present for the first time a comprehensive statistical study on metric type II radio bursts (m-IIs) and their associated solar and space weather (SW) phenomena, namely, solar flares (SFs), sunspot (SN) configu- rations, coronal mass ejections (CMEs), their interplanetary (IP) counterparts (ICMEs) and shocks, filaments, in situ detected particles and geomagnetic storms (GSs). The radio signatures were identified from dynamic spectra provided by the ground-based RSTN network distributed over the globe with nearly complete diurnal coverage. Based on the recently completed catalog of m-IIs in solar cycle 24, we perform the temporal and spatial association between the radio emission and listed above activity events. The remaining data is collected from various space-based satellites, ground-based observatories or public catalogs. We complement the m-II results with m+IP IIs where the IP IIs are identified from the Wind/WAVES spacecraft. Occurrence rates are calculated and presented as a function of the strength of the specific SW event type: higher rates are obtained with CMEs, SFs, and SN configurations, whereas a much weaker relationship is found with ICMEs, IP shocks, energetic particles, and GSs. The obtained relationships can be utilized in empirical or physics-based models for SW forecasting.
CSSMA: A novel algorithm of slime mold optimzer for global optimization problems

Published: August 2023

Abstract

The Slime Mold Algorithm (SMA) is a popular optimization algorithm in recent years. However, it suffers from weaknesses in exploration capability, insufficient balance, and a tendency to get trapped in local optima. To address these issues, this paper proposes a novel Slime Mold Algorithm based on Cosine Similarity and Population Range Neighborhood Selection Mechanism (CSSMA).Firstly, a population range neighborhood selection mechanism is designed to enhance the algorithm's exploration capability. This mechanism allows for a better exploration of the solution space during the optimization process. Next, an embedded uniform nonlinear adaptive operator is introduced to improve the balance between exploration and exploitation in SMA. This step ensures that the algorithm can effectively explore promising areas while also exploiting the identified regions.Moreover, a cosine similarity-based escape mechanism is proposed to enhance the optimization precision and promote population diversity in SMA. This mechanism assists the algorithm in breaking away from local optima and exploring the global solution space more effectively.In the validation phase, CSSMA is evaluated using 12 selected test functions out of 23 classic test functions through ablation experiments. Additionally, numerical experiments and Wilcoxon rank-sum tests are performed on all 23 test functions to compare the performance of the proposed improvements with other benchmark algorithms. The results validate the effectiveness of the proposed CSSMA, as it demonstrates a significant improvement in optimization precision and overall performance, making it more competitive than other compared algorithms.
CNN-based Hot-Rolled Steel Strip Surface Defects Classification: A Comparative Study Between Different Pre-Trained CNN Models
Authors: Bouguettaya Abdelmalek , Zarzour Hafed 
Published: August 2023

Abstract
During the manufacturing process, hot-rolled steel strip surface defects occur frequently. These defects cause economic losses and risks in the use of these products. Therefore, it is crucial to develop automatic inspection systems to identify these defects. In the last few years, computer vision has emerged as an effective tool to identify these defects. Deep learning-based computer vision techniques, especially Convolutional Neural Networks (CNN), achieved state-of-the-art results for most computer vision tasks, including image classification. These results are obtained using a large amount of data. However, collecting such large datasets in the manufacturing field remains a challenging task. To overcome such a problem, a transfer learning-based framework with multiple CNN variants is proposed in this study. Therefore, different state-of-theart and widely used pre-trained CNN architectures, including VGG-16, VGG-19, ResNet50, ResNet50V2, InceptionV3, InceptionResNet-V2, MobileNet-V1, MobileNet-V2, MobileNet-V3 Small, and NASNetMobile, combined with transfer learning were investigated to evaluated their performances in classifying hot-rolled steel strips surface defects. The experimental results showed that MobileNet-V2 and InceptionResNetV2- based methods achieve better performance than all other models in terms of accuracy, loss, training and inference times, and model size.
