Marriage in the Age of Advancement of Digital Technology: Study of Nahdlatul Ulama and Muhammadiyah Fatwa on the Legality of Marriage via Online
Authors: Wajidi Farid , Mustafid Fuad
Published: March 2024

The phenomenon of online marriage contracts is starting to emerge and this raises issues regarding its validity. Majelis Tarjih dan Tajdid Muhammadiyah and Bahtsul Masail Nahdlatul Ulama have responded and issued fatwas related to this issue with different legal conclusions. This article examines and explains the causes of differences in fatwas and at the same time arguments issued by Muhammadiyah and Nahdlatul Ulama regarding the law of online marriage contracts. Using the usul fiqh approach, this article finds two findings. First, there is a difference in fatwas between Muhammadiyah and Nahdlatul Ulama due to differences in the legal istinbath method; Muhammadiyah uses the burhani method, while Nahdlatul Ulama uses the qauli method. Second, Muhammadiyah interprets the concept of ittihad majelis as a continuity of time between ijab and qabul, while Nahdlatul Ulama interprets it as a unitary place and not merely a unitary speech. This has implications for the legal status of online marriage contracts. Muhammadiyah considers online marriage contracts via online as a valid contract, while Nahdlatul Ulama considers it invalid.

Published: March 2024

This Regional Sediment Management technical report outlines initial steps to implement a proof-of-concept physical model to develop demonstration-scale evidence that supports managed wetland transgression through sediment augmentation via a thin-layer placement strategy. The proof-of-concept physical model will evaluate the ability of thin-layer placement to increase elevation and enhance recruitment within coastal scrub mangrove wetlands most vulnerable to sea-level rise. The investigation sought to identify feasible project locations, sediment sources that included beneficial use of dredged material opportunities, and environmentally acceptable construction techniques. Results of this initial step will be used to secure funding to permit, construct, implement, and monitor the proof-of-concept physical model. The results of this initiative will inform and direct management measure development for the ongoing Biscayne Bay Southeastern Everglades Restoration Project, the only coastal component of the Comprehensive Everglades Restoration Plan and the only component with an obligation to increase habitat resilience. Results are applicable to areas throughout the Gulf, Atlantic, and Pacific Coasts of the United States where direct preservation, enhancement, and restoration of mangrove and other coastal wetland communities will build coastal resiliency, reduce storm hazards damage, and create habitat for a variety of fish and wildlife species, particularly as sea levels rise.

A Model of Election Supervision Based on Village Judicial Institutions; A Review of Legal Anthropology in Madura
Authors: Da Silva Eugenia Brandao , Ali Mahrus , Rohman Khabib Syaikhu , Mashud Mashud
Published: March 2024

The General Election Law has placed villages at the forefront of the election monitoring system by establishing Village Panwaslu. However, it still needs to be fully able to unravel the complexity of the election monitoring system. This study aims to strengthen the election supervision system so that all electoral issues can be resolved at the village level. This research uses normative legal research methods that focus on the reconstruction and institutionalization of the election supervision system at the village level through the synergy of village judicial institutions. The result of the research is that the design of election supervision at the village level, which only places one member, has yet to resolve the many burdens of election supervision fully. Although Article 448 paragraph (3) of the Election Law authorizes the community to monitor actively, it has proven not optimal because there is no clear legal protection for the participatory monitoring system. The weakness of the monitoring system can be strengthened through 1) The establishment of Village Panwaslu members that involve village judicial institutions consisting of Babinkantibmas, Babinsa, and community leaders; 2) Expanding the authority of the Village Panwaslu to resolve disputes over the election process at the village level.

Published: March 2024

Sampang is an area that has the largest salt field in Madura. But the existence of abundant salt fields does not make it a developed region. Sampang has consistently been a disadvantaged area. Thus, predictably, there are various problems regarding salt in Sampang. This issue needs to be studied, especially on legal issues that hinder the development of the salt industry in Sampang. To answer this problem, empirical legal research methods are used to explore and identify legal problems that occur in the field related to salt issues. The results and discussion in this study revealed that there are at least three main problems that hinder the progress of the salt industry perspective of salt farmers in Sampang Regency. The three main problems are the absence of regional regulations on aquaculture, the absence of regional policies that support salt pricing that benefits farmers, and the absence of policies on the implementation of regional duties in the field of providing facilities and infrastructure that support the development of the salt industry in Sampang Regency.

Published: March 2024

The Metaverse, a virtual space encompassing augmented reality, virtual reality, and the internet, has witnessed rapid growth, giving rise to complex economic activities. However, it suffices to state that despite the relevance of the metaverse concept in the global terrain, Nigeria, like many nations, could face the challenge of adapting its tax laws to the unique characteristics of the Metaverse. Given this, this study adopts a hybrid method of study to explore the taxation challenges within the Nigerian Metaverse, evaluating the efficacy of current tax laws and regulations in this evolving digital landscape. In this regard, 352 questionnaires were distributed to legal practitioners residing in Nigeria to ascertain their views concerning the sufficiency and deficiency of the existing tax laws regulating the tax issues in the metaverse. The study's findings reveal significant challenges in existing tax laws, including jurisdictional complexities, defining taxable income in virtual environments, identifying entities subject to taxation, enforcing regulations without physical assets, overcoming technology gaps, and ensuring legislative adaptability to digital advancements. These challenges hinder the growth of the Metaverse industry and pose risks in revenue generation within the metaverse operation in Nigeria. It was therefore concluded that there is an urgent need to adapt tax policies to the unique characteristics of the Metaverse in Nigeria. A balance between innovation and regulatory oversight is crucial for sustainable growth in the virtual economy. In this regard, the study recommended clear definitions and classifications of virtual assets, considering international best practices and collaborating with international bodies to establish a comprehensive and adaptive legal framework for taxing Metaverse activities in Nigeria.

LRCM: Enhancing Adversarial Purification through Latent Representation Compression
Authors: Li Yixin , Luo Xintao , Wu Weijie , Zheng Minjia
Published: March 2024

In the current context of the extensive use of deep neural networks, it has been observed that neural network models are vulnerable to adversarial perturbations, which may lead to unexpected results. In this paper, we introduce an Adversarial Purification Model rooted in latent representation compression, aimed at enhancing the robustness of deep learning models. Initially, we employ an encoder-decoder architecture inspired by the U-net to extract features from input samples. Subsequently, these features undergo a process of information compression to remove adversarial perturbations from the latent space. To counteract the model's tendency to overly focus on fine-grained details of input samples, resulting in ineffective adversarial sample purification, an early freezing mechanism is introduced during the encoder training process. We conducted experiments using the proposed model to purify adversarial samples generated by various methods using CIFAR-10 and ImageNet datasets. The experimental results revealed a notable increase in accuracy when employing the ResNet classifier.
Foregone carbon sequestration loss dominates greenhouse gas budget in mariculture associated with coastal wetland conversion
Authors: Ding Weixin , Yuan Junji , Dong Yanhong , Li Junjie , Liu Deyan , Xiang Jian , He Tiehu , Kang Hojeong
Published: March 2024

Coastal wetlands represent a disproportionately large global carbon (C) sink. However, they are threatened by the ever-expanding aquaculture and being lost at critical rates. Conversion of coastal wetlands to aquaculture systems has been predicted to result in significant C losses, yet accurate assessments of greenhouse gas (GHG) budgets associated with this major perturbation are rarely available. Here we show that the conversion of Spartina alterniflora saltmarsh to mariculture ponds in China induced a dramatic shift from net atmospheric GHG sink (‒13.8 Mg CO2eq ha–1 yr–1) to net GHG sources (2.16 Mg CO2eq ha–1 yr–1), creating a full GHG debt of 15.9 Mg CO2eq ha–1 yr–1. The loss of foregone GHG mitigation capacity of saltmarsh makes the largest contribution (86.4%), while only 15.6% of the total debt arises from direct CO2, CH4, and N2O fluxes in the mariculture ponds. But considering the main drivers of GHG emissions from animal protein production, mariculture has much lower GHG-cost than inland freshwater aquaculture and terrestrial beef, small ruminants, and pork production on a kg CO2eq kg‒1 protein basis. The low-C mariculture could be further realized by avoiding devastation of vegetated coastal wetlands and minimizing CH4 emission by carrying out in high-salinity waters.

Published: March 2024

This study introduces an innovative strategy, termed the "epoxidation & combination" approach, to create cost-effective and mechanically enhanced 3D printing photocurable materials by using waste cooking oil (WCO) as raw material. Within this strategy, WCO is first subjected to epoxidation, yielding epoxy waste cooking oil (E-WCO). Subsequently, E-WCO is combined with triethylene glycol dimethacrylate (TEGDMA) to formulate a E-WCO plasticized TEGDMA photocurable resin suitable for 3D printing. Functioning as a plasticizing component, E-WCO effectively resides within the TEGDMA substrate with minimal migration (0.30% at 135℃ for 24 hours). Furthermore, appropriate addition of E-WCO significantly enhances the mechanical properties of the TEGDMA-based resin, especially in terms of toughness. The optimized composition of the E-WCO/TEGDMA 3D printing resin, with an E-WCO : TEGDMA mass ratio of 1:15, demonstrates exceptional mechanical strength. This includes a tensile strength of 16.74 MPa, an elongation at break of 32.93%, and an impact strength of 3.94 kJ/m2, surpassing the benchmarks of pure TEGDMA. When compared to commercial epoxy soybean oil (ESO), E-WCO provides an equivalent plasticizing effect, effectively enhancing material flexibility. The transformation of WCO into the E-WCO/TEGDMA resin not only promotes the high-value utilization of WCO but also holds significant potential for developing low-cost and sustainable 3D printing consumables.

Multichannel meta-imaging, inspired by the parallel-processing capability of neuromorphic computing, offers significant advancements in resolution enhancement and edge discrimination in imaging systems, extending even into the mid- to far-infrared spectrum. Currently, high-performance multichannel infrared imaging systems typically consist of separate detector arrays and gratings or multi-camera integration, which require complex circuit design and heavy power consumption, hindering the implementation of advanced human-eye-like imagers. Here, we present a novel approach for printable graphene plasmonic photodetector arrays with zero-bias operation driven by a ferroelectric superdomain for multichannel meta-infrared imaging with enhanced edge discrimination. The fabricated photodetectors exhibited multiple spectral responses by directly rescaling the ferroelectric superdomain instead of reconstructing the gratings. We also demonstrated enhanced and faster shape classification (98.1%) and edge detection (98.2%) using our multichannel infrared images compared with single-channel detectors. Our proof-of-concept photodetector arrays simplify multichannel infrared imaging systems and hold great potential for applications in efficient edge detection in human-brain-type machine vision.
Construction and Optimization of Wilderness Networks in the Southwest Border Biodiversity Tropical Areas Based on Naturalness and Connectivity
Authors: Li Jian'e , Zhang Yun
Published: March 2024

The preservation of the region's biodiversity is seriously threatened by the area's growing urbanization. Because of the abundance of biodiversity in Xishuangbanna Prefecture, it is crucial to create wilderness networks that link scattered wilderness areas and enhance network connection to preserve wilderness areas and ecosystem stability. Boolean overlay and Weighted Linear Combination (WLC), two methods for integrating wilderness mapping, were used in this work to identify the wilderness patches and wilderness maps. Morphological spatial pattern analysis (MSPA) and connectivity analysis were used to locate the wilderness source and structural corridor, respectively. The wilderness source was then extracted using the Minimal Cumulative Resistance Mode (MCR) model and the Linkage Mapper potential corridor tool. Construct the wilderness network by superimposing each indicator, and optimize the wilderness network by adding wilderness sources, building footstones, and adding wilderness corridors. Results show that the constructed wilderness network included 57.37hm2 of structural corridors, 15 wilderness source areas, 31 wilderness potential corridors, and 27 ecological pinch points. The wilderness network was optimized by adding 4 wilderness source sites, 9 stepping stones, and 6 wilderness addition corridors, the optimized wilderness network connectivity was improved, with the α, β, and γ values increasing by 0.16, 0.29, and 0.11, respectively. To better protect areas of high wilderness value in the biodiversity tropics along South-west China's border and enhance the nature reserve system, this study analyses the wilderness network's connectivity based on naturalness and connectivity. It also offers reference data for the development of policies such as territorial spatial planning, the delineation of the ecological protection red line, and the ecological protection and restoration of mountains, waters, forests, lakes, and grasslands.
Disseminated Mycobacterium haemophilum infection in an immunocompromised host: A complex case with immune reconstitution inflammatory syndrome (IRIS) manifestation
Authors: Choi Ming Hong , Wu Hao , Yuen Kwok Yung , Hung Ivan Fan Ngai
Published: March 2024

Background
Mycobacterium haemophilum is a rare but significant opportunistic pathogen known to cause infections in immunocompromised individuals. Despite its low prevalence, disseminated infections with this organism can present diagnostic and therapeutic challenges, particularly in hosts with compromised immune systems. The phenomenon of Immune Reconstitution Inflammatory Syndrome (IRIS) further complicates the clinical course and management of such cases.
Case Presentation
: A 39-year-old male patient with a medical history of T-cell acute lymphoblastic leukaemia (T-ALL) who underwent a matched unrelated donor haematopoietic stem cell transplantation four years prior presented with fever and rash affecting all four limbs and the back. Subsequent evaluation confirmed a diagnosis of cutaneous Mycobacterium haemophilum infection, which was found to have disseminated to multiple organ systems including the lungs, gastrointestinal tract, and nasal turbinate. Treatment initiation resulted in immune reconstitution inflammatory syndrome (IRIS), posing challenges in managing the infection in the context of heightened immune response post-reconstitution. This case highlights the complexities involved in managing disseminated mycobacterial infections with IRIS following immune reconstitution.
Conclusion
This case highlights the diagnostic dilemmas and therapeutic considerations in managing disseminated Mycobacterium Haemophilum infection in immunocompromised hosts. The manifestation of IRIS further complicates the clinical course, necessitating a multidisciplinary approach to optimize patient outcomes. Our experience underscores the importance of early recognition, tailored antimicrobial therapy, and meticulous monitoring in managing such cases, with implications for clinicians caring for immunocompromised patients.

Published: March 2024

Background and Aim: There is increasing evidence that semen quality reflects the overall health status of individuals and is a marker of future health. In addition, reproductive hormones have significant regulatory effects on the immune system and the function of inflammatory cells. In this study, it was aimed to investigate whether baseline semen quality and serum reproductive hormone levels are potential indicators of susceptibility to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
Methods: The medical records of a total of 1303 patients who underwent semen analysis and hormonal evaluation including total testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin (PRL for infertility or other medical reasons were retrospectively analyzed. Among these patients, 316 were determined to have previously been exposed to SARS-CoV-2 infection.
Results:There was no statistically significant difference in baseline hormone profile (FSH, LH, PRL, and total testosterone) and semen parameters between patients exposed to SARS-CoV-2 infection and non-exposed patients.
Conclusions: This study demonstrated that baseline semen quality and serum reproductive hormone levels (total testosterone, PRL, FSH, and LH) are not indicators of susceptibility to SARS-CoV-2 infection.

Objectives: Vertebroplasty via extrapedicular approach is used in privileged patients in osteoporotic vertebral fractures. Many experimental studies but few clinical studies were conducted. This study aimed to compare extrapedicular percutaneous vertebroplasty to a transpedicular approach radiologically.
Material and Methods: Seventy-nine vertebrae of 53 patients who were treated by extrapedicular and transpedicular vertebroplasty were included in the study. The anterior, middle, and posterior heights of the compressed vertebrae were measured by a technique described by Genant et al. preoperatively and postoperatively by two independent researchers on lateral plain radiographs of the patients. Both the systemic and local complications related to the procedures were enrolled.
Results: Thirty vertebrae were thoracal, and 49 vertebrae were lumbar. The mean follow-up was 14.2±3.6 Months. Thirteen thoracal vertebrae and 14 lumbar vertebrae were operated on via extrapedicular approach, and 17 thoracal, and 35 lumbar vertebrae via transpedicular approach. The mean height of the vertebrae's anterior, middle, and posterior heights was 17.8±6.9 mm, 15.7±6.5 mm, and 25.4±5.2 mm. There was a statistically significant increase in the height of all three columns in both approaches. There were no differences in terms of adjacent and distant fractures. Twenty-three patients had cement leakage into extraosseous tissues. Thirteen patients to the paravertebral soft tissues, seven patients to the intervertebral disc space, and three to the paravertebral vessels.
Conclusion: Extrapedicular percutaneous vertebroplasty is a reliable and effective method similar to transpedicular route in terms of regaining all vertebral column height regain and complications.

Purpose: The aim of this study was to compare the potential risks of acetaminophen and ibuprofen use during pregnancy in relation to adverse events (AEs) from real-world practice via the FAERS database.
Methods: We detected signals of the AEs of acetaminophen and ibuprofen use during pregnancy by data mining using FAERS database. Disproportionality analysis was used to the FAERS for the suspected pregnancy data from January 2017 to December 2022.
Results: On the basis of 51,936 acetaminophen reports, the reports of 331 (0.64% of total adverse drug reactions, ADRs) were associated with pregnancy; On the basis of 84,810 ibuprofen reports, the reports of 530 (0.62%) were associated with pregnancy. Among acetaminophen reports, the most AE was exposure during pregnancy (59.52%) that belongs to injury, poisoning and procedural complications. The associated pregnancy outcome of those reports was missing may suggest no cause serious consequences. Among ibuprofen reports, the major AE was abortion spontaneous (26.79%), and oligohydramnios (17.74%).
Conclusion: This is the first study of comprehensively compare and analyze the potential risks between acetaminophen and ibuprofen for drug-associated adverse fetal and pregnancy outcomes by assessing the reported AEs from the real-world database. The results suggested acetaminophen may be the better choice during pregnancy.

Published: March 2024

In this work, poly(α-methyl styrene) (PAMS) was synthesized through living anionic polymerization and characterized by 13C NMR, 1H NMR, GPC, TGA, DSC. The kinetics study was performed using multi-stage dosing of initiator. The results obtained via GPC analysis revealed that polydispersity index of the synthesized PAMS was close to the true value. Moreover, multi-stage dosing of initiator offers valuable and accurate method to determine propagation rate constant and initial impurities value of the system. 13C NMR analysis demonstrated that Bernoullian statics model exhibits a superior fit compared to 1st -order Markov statics model for the assigned sequence. Furthermore, the synthesized PAMS presents higher degree of racemic addition with Pm=0.439. 1H NMR spectroscopy was utilized to ascertain number-average molecular weight of the synthesized samples, corroborating the values estimated through GPC analysis. From the thermal analysis, it was shown that PAMS containing very low molecular weight demonstrates negative glass transition temperature and broad thermal decomposition range.

Published: March 2024

The increasing food demand for a growing population has resulted in the intensification and modernization of agriculture leading to an increasing use of pesticides to protect crops against insects, weeds, fungi, and other pests. However, these chemical compounds can cause adverse effects on the environment due to their low biodegradability and toxicity. This study assesses the use of DuPont FilmTec™ NF270 and FilmTec™ XLE membranes for the removal of six pesticides (atrazine, simazine, isoproturon, metolachlor ESA, 2,4-D, and chlorothalonil) in aqueous streams. The results reported average rejection rates of 29.25–89.36% and > 97% in the nanofiltration and reverse osmosis membranes respectively, showcasing that membrane technology is effective for the removal of these pollutants from wastewater streams. However, a customised selection of the membrane (nanofiltration/reverse osmosis) should be performed depending on the targeted pollutants in order to balance the pesticide rejection and energy consumption for each market application.

Backgroun
Birth asphyxia stands out as a significant factor contributing to morbidity and mortality among newborns. However, the determinants of birth asphyxia have not been thoroughly investigated within the local context, particularly in this specific area. Hence, this study aims to identify these determinants to tackle the issue effectively.
Objectives
The goal of this study is to pinpoint the determinants of birth asphyxia at Bekoji Public Hospital in Bekoji Town, Arsi Zone, Oromia Region, Southeast Ethiopia, in 2023.
Methods
A case-control study was conducted between June 1, 2023, and August 30, 2023. A total of 198 newborns (75 cases and 123 controls) at Bekoji Public Hospital were selected using a systematic random sampling technique. Data collection involved a checklist for record review and an interviewer-administered questionnaire. The data were entered into EpiData version 7.1 and analyzed using SPSS version 25. Variables with a P-value < 0.25 were subjected to multivariable regression analysis. The Odds Ratio estimated with a 95% Confidence Interval was utilized to indicate the strength of association, with a significance level set at P < 0.05.
Results
196 mothers of newborns (73 cases and 123 controls) were interviewed, resulting in a response rate of 98.9%. Factors such as prolonged duration of labor (AOR = 2.54; [95% CI: 1.78, 6.39]), delivery by Caesarean section (AOR = 0.64; [95% CI: 0.004, 1.114]), presence of stained amniotic fluid (AOR = 0.473; [95% CI: 0.180, 1.242]), and non-cephalic fetal presentation (AOR = 2.12; [95% CI: 1.019, 3.80]) were identified as predictors of birth asphyxia. Additionally, being male (AOR = 1.885; [95% CI: 0.899, 3.950]) was also found to be a predictive factor for birth asphyxia.
Conclusion and Recommendations:
Duration of labor, fetal presentation, type of amniotic fluid, mode of delivery, and the gender of newborns emerged as significantly associated factors with birth asphyxia. As a result, interventions targeting these factors, particularly focusing on duration of labor and fetal presentation, should be rigorously implemented.
