Mohammed Arkoun’s Thought on Sharia Deconstruction: A Historical and Anthropological Approach
Authors: Syar'i Makmun
Published: January 2023

This article explores Mohammad Arkoun’s thoughts on understanding Islamic Sharia in the modern world. Arkoun’s thought differs from previous Islamic thinkers in analyzing Islamic texts. Arkoun exceeded the limit of traditional Islamic studies by utilizing several elements from Modern Western philosophy, social sciences, and humanities. Arkoun took this effort to realize his ambition, which was the combination of valuable thoughts from Islamic notions and modern philosophy. In the philosophy of Islamic law, the combination in line with the particular theorem stated: “al-muhāfaẓah `alā al-qadīm al-ṣālih wa al-akhdzu `alā al-jadīd al-aṣlah” (literary means keeping good old traditions and adopting a new better ones). Islamic sharia should be related to historical context. According to Arkoun, the traditional and textual paradigm in understanding Islamic sharia leads people to misunderstand Quranic interpretation. People sanctify Islamic thoughts instead of understanding the substantial meaning behind the Quranic texts. Arkoun called this phenomenon “taqdīs al-Afkār ad dīniyyah” (sanctifying religious thoughts). This study finds that Arkoun’s thoughts are close to an anthropological and historical approach. The Quranic interpretation has to look at both universal and particular texts of the Quran by deconstructing the logic and discourse that underlay the emergence of these texts.

 

Keywords: Muhammad Arkoun, Quranic interpretation, sharia deconstruction, historical and anthropological approach.
Negotiating Muslim Interfaith Marriage in Indonesia: Integration and Conflict in Islamic Law
Authors: Nasir Mohamad Abdun
Published: January 2023

Conflict can emerge from marriage involving parties of a different faith. However, interfaith marriage may also expose negotiation to secure the union. Although interfaith marriage is normatively restricted in Islamic law, it does occur. This study departs from the normative discourse of Islamic law and the empirical research of Muslim family law. It uses the theory of law, conflict, and integration to analyse the textual debates and practice of interfaith marriage in Lombok, Indonesia. This study reveals the patterns of Muslim interreligious marriage and the conversion that applies. The first pattern shows that non-Muslim partners convert to Islam before the marriage can be concluded. The second pattern involves Muslims who leave Islam to marry their non-Muslim partner. The third pattern suggests that each couple adheres to a different belief during the marriage even though the marriage contract was performed according to Islamic law. From the perspective of Islamic law, in the sense of sharia and Muslim family code, the first pattern is the most ideal because it follows these Islamic legal normativities. Although all practices have the potential for family and social integration, the second pattern is the most susceptible to conflict.

Keywords: interfaith marriage, conflict, integration, Islamic law

_

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 208547, “Locating Source of Water Production and Performing Cost‑Effective Rigless Remedial Operations in Deviated Wells Completed With Standalone Sand Screens,” by Andrey Timonin, SPE, Schlumberger, and Eldar Mollaniyazov, Dragon Oil. The paper has not been peer reviewed.

_

Field examples presented in the complete paper describe a fit-for-purpose logging approach for locating sources of water production accurately and executing rigless water-shutoff operations to increase cost-effective hydrocarbon production in cased wells completed with standalone sand screens. After remedial operations, the authors observed a significant decline in water production and an increase in oil rates in all remediated wells.

Introduction

The operator was granted a production license for exploration and development of oil and gas resources in the Cheleken Contract Area in the Caspian Sea. The area consists of two offshore oil and gas fields, Dzheitune (LAM) and Dzhygalybeg, in water depths between 8 and 42 m. The fields consist of two elongated anticlines at the eastern end of the prolific hydrocarbon Apsheron Ridge. The LAM field is a multilayer reservoir with pressure regimes producing at various gas/oil ratios with complex inflow profiles downhole.

Most of the wells drilled in the LAM field were completed with 9.625-in. casing and 7-in. liner across the reservoir section. The A sand reservoir, at depths of 1500–1800 m, and the CH sand reservoir, below 2000 m, are produced separately by using dual-string tubing to avoid crossflow.

Over time, depletion in reservoir pressure caused formation failure in the A sand reservoir. Wells producing from this formation began to produce sand. As a result, the operator had to change the completion strategy for newly drilled wells and recomplete some old wells by pulling dual-string completions out of hole and running in hole single tubing with sand screens across existing perforations.

Some wells completed with standalone sand screens across the A sand reservoir experienced water breakthrough over time. Locating the source of water breakthrough and achieving timely intervention to shut off water inflow is paramount to keeping these wells producing at economically optimal oil rates.

Overview of Rigless Wireline Logging and Intervention Techniques

Rigless wireline logging and intervention techniques, the implementation and components of which are detailed in the complete paper, were used in several wells in the LAM field to shut off water production in a cost-effective way. The three field examples demonstrate rigless logging and intervention results in wells completed with standalone sand screens.
System performance and Optimization in NOMA Mobile Edge Computing Surveillance network using GA and PSO
Authors: Truong Truong Van , Nayyar Anand
Published: January 2023

Recent years have witnessed the process of computing gradually move to the edge network, where it is close to the physical data source, to serve applications that require large computations with very little latency. However, the terminal wireless devices’ limited computing and energy resources pose obstacles to the practical implementation of these applications. Mobile Edge Computing (MEC) based non-orthogonal multiple access (NOMA) technology is solving this problem well thanks to its ability to serve many users with high data rates and spectrum utilization efficiency. This study investigates the performance and optimization of MEC surveillance systems using NOMA. Specifically, two camera units (CUs) perform the monitoring task to be accomplished by the MEC access point (AP) through Rayleigh fading wireless links. We then proposed the four-phase protocol for this system. Accordingly, we derive the closed-form exact expressions of the successful computation probability (SCP), and study the impact of the network parameters on the system performance. Furthermore, we propose and compare three meta-heuristic-based algorithms, namely MSCP-GA, MSCP-PSO, and MSCP-HGAPSO, to find the optimal parameters set to help the proposed system achieve the maximum SCP. The results show that the proposed algorithms can significantly improve the system's performance by 40% higher than when the optimal algorithm is not used. Insights on the pros and cons of different algorithms are also discussed in this study. Finally, we use the Monte-Carlo simulation to verify the correctness of this study.
Adult-born neurons maintain hippocampal cholinergic inputs and support working memory during aging.

Published: January 2023

Adult neurogenesis is reduced during aging and impaired in disorders of stress, memory, and cognition though its normal function remains unclear. Moreover, a systems level understanding of how a small number of young hippocampal neurons could dramatically influence brain function is lacking. We examined whether adult neurogenesis sustains hippocampal connections cumulatively across the life span. Long-term suppression of neurogenesis as occurs during stress and aging resulted in an accelerated decline in hippocampal acetylcholine signaling and a slow and progressing emergence of profound working memory deficits. These deficits were accompanied by compensatory reorganization of cholinergic dentate gyrus inputs with increased cholinergic innervation to the ventral hippocampus and recruitment of ventrally projecting neurons by the dorsal projection. While increased cholinergic innervation was dysfunctional and corresponded to overall decreases in cholinergic levels and signaling, it could be recruited to correct the resulting memory dysfunction even in old animals. Our study demonstrates that hippocampal neurogenesis supports memory by maintaining the septohippocampal cholinergic circuit across the lifespan. It also provides a systems level explanation for the progressive nature of memory deterioration during normal and pathological aging and indicates that the brain connectome is malleable by experience.
Remote control of the retroflection of the Labrador Current
Authors: Jutras Mathilde , Dufour Carolina , Mucci Alfonso , Talbot Lauryn
Published: January 2023

The Labrador Current carries cold, relatively fresh, and well-oxygenated waters into the subpolar North Atlantic and into the Slope Sea. The relative contribution of these waters to either region depends on the eastward retroflection of the Labrador Current at the Grand Banks. We develop a retroflection index based on virtual Lagrangian particles and show that the amplitude of the retroflection is mostly controlled remotely by large-scale forcing, related to winds over the Labrador Shelf and to subpolar gyre dynamics, whereas eddies and meanders arising from interactions between the Labrador Current and the Gulf Stream play a secondary role. The mechanistic understanding of the drivers of the Labrador Current retroflection should help to predict changes in the water properties of both export regions, and anticipating their important consequences on marine life and deep-water formation.
Ramifications of Sectors Economic Upsurge on rate of early aged Unemployment in case of East African Countries
Authors: Alemu Ferede Mengistie
Published: January 2023

The issue of economic intensification is a requirement of expanding economic triggers in various sectors, whereas adolescence unemployment is a significant economic and human capital crisis that has been exacerbated by frequent economic crises. Panel data from 2007 to 2016 were used to investigate the effects of economic intensification on youth unemployment in East African countries. The Random Effect model was used for the analysis. The study's findings confirm that foreign direct investment, vulnerability to employment, internet access, and export volume all have a negative impact on early aged unemployment at a 10% level of significance. Other variables such as agriculture value addition, manufacturing value addition, dependency ratio, and education all had a positive impact on youth unemployment in East African countries. Based on the findings, policymakers should focus on strategies that can increase investments in agriculture, industry, and services, which can increase the economic sector's labor absorptive capacity.
Extraction of bioethanol from Jatropha deoiled cake as a potential feedstock & its blending effects on the performance of single-cylinder SI engine
Authors: Deshmukh Minal , Pande Ashwini , Choudhari Vishnu , Pendse Dhanashri
Published: January 2023

Alternatives to conventional fuel sources have to be found because of the depletion of fossil fuels and stringent regulatory regulations. Every day, the growing population and improved transportation increase the energy demand. Agriculture and food waste management, as well as pollution, remain major issues that require attention. Bioethanol is an effective substitute for gasoline and SI engine diesel. Worldwide, passenger cars typically blend 10 % bioethanol with gasoline. Some nations, like India, have stated plans to blend 20% bioethanol with gasoline starting shortly. This paper describes the process of extracting ethanol from leftover Jatropha deoiled cake (JDC) and various blends' effects on spark-ignited engines' performance. From leftover JDC, bioethanol was produced utilizing the fermentation and vacuum distillation methods. Four different blends were prepared on a volumetric basis at different engine speeds at a constant compression ratio of 10:1 and the wide-open throttle was tested for various performance and emissions. Bioethanol enrichment increased indicated power, volumetric efficiency, and mechanical efficiency. Bioethanol enrichments reduce HC, CO, and CO2 emissions but increase nitrogen oxide emissions. JDCE 15 was found to have the best engine performance out of all the fuel blends tested. This study suggests that, if NOx emission reduction measures are carried out, JDC can be used as a source for the manufacturing of second-generation bioethanol. This research work is eco-friendly solution for bioethanol production.

Authors: Noronha Noella , Shah Aimun Qadeer , Chin-See Robert , Hanna Christina , Kadri Zeest , Marwaha Amn , Rambharack Neetu , Ng Jeremy Y
Published: January 2023

Background: Telemedicine includes the delivery of health-care services and sharing of health information across distances. Past research has found that telemedicine can play a role in enhancing complementary, alternative, and integrative medicine (CAIM) while allowing the maintenance of cultural values and ancestral knowledge. This scoping review synthesized evidence regarding the use of telemedicine in the context of CAIM.
Methods: Following Arksey and O’Malley’s scoping review framework, CINAHL, PsycINFO, MEDLINE, EMBASE and AMED databases were searched systematically. The CADTH website was also searched for grey literature. Eligible articles included a CAIM practice or therapy offered through telemedicine, with no restrictions placed on the type of telemedicine technology used. Inductive thematic analysis was conducted to synthesise common themes among the included studies.
Results: Sixty-two articles were included in this synthesis. The following themes emerged: 1) the practitioner view of CAIM delivered through telemedicine, 2) the patient view of CAIM delivered through telemedicine, and 3) the technological impacts of telemedicine delivery of CAIM.
Conclusions: Studies have shown that telemedicine delivery of CAIM is feasible, acceptable, and results in positive health outcomes. Some barriers remain such as existing illness and morbidity, inability to form strong patient-provider relationships relative to face-to-face approaches, and technological difficulties. Future intervention research should focus on reducing such barriers, as well as explore which patient population would realize the greatest benefit from CAIM delivered via telemedicine, and the impact of interventions on providers and caregivers.
The Influence of Financial Development on Wealth Inequality in Capitalism: Fresh Evidence from Emerging Countries
Authors: Cengiz Orhan , Manga Müge
Published: January 2023

Our paper investigates the impact of financial development on wealth inequality for the ten emerging countries, Brazil, China, India, Indonesia, Malaysia, Mexico, Philippines, South Africa, Thailand, and Turkey, from 1995 to 2020 by observing the effect of economic growth and trade openness. By applying the augmented mean group (AMG) estimator, the empirical findings reveal that financial development causes increasing wealth inequality for panel groups. Also, this increasing effect has been observed in Brazil, China, Mexico, and the Philippines. Moreover, economic growth and trade openness positively impact wealth inequality for panel samples. Dumitrescu and Hurlin’s (2012) causality test results indicate a two-way causality relationship among financial development and wealth inequality, economic growth and wealth inequality, wealth inequality and trade openness. Our paper highlights the major policy implementation that the government intervention plays a vital role in facilitating equal access to financial assets for lower-income people.
Finite-time adaptive control for microgravity vibration isolation system with full-state constraints
Authors: Ma Guangcheng , Wang Aixue , Wang Shuquan , Xia Hongwei , Zhang Long , Liu Wei
Published: January 2023

This article proposes a finite-time adaptive control strategy for a class of vibration isolation systems with external disturbances and full-state constraints. Time-varying barrier Lyapunov functions (TBLFs) are designed to achieve suppression performance under limited rattle space. Adaptive laws are applied to deal with parameters uncertainty which is caused by various mass and momentum. By regarding internal coupling terms and external disturbances as lumped disturbances, a predefined-time observer is employed to handle them. Furthermore, command filters are used to remove the burdens of the computational explosion. With the aid of auxiliary system, command filters errors are eliminated. And the actuator saturation is addressed by auxiliary system as well. By using the finite-time Lyapunov stability theory, it proves that all the states converge in finite time. Finally, simulations are given to verify the effectiveness and benefits of the developed control strategy with a trade-off between the improved suppression performance, limited mechanical constraints and robustness.
Dynamic Characteristic of Rudder Loop with Rough Revolute Joint Clearance
Authors: Guo Jianan , Wang Yingzan , Zhang Xingwei , Cao Sheng , Liu Zhansheng
Published: January 2023

The joint clearance of rudder loop has a significant impact in achieving the high-precision attitude control of aircraft. This study proposed a novel revolute joint clearance contact model considering surface topography. Such a model identified that the impact dynamic characteristics were significantly influenced by parameters such as contact speed, roughness, and curvature radius of asperities. The dynamic model of the rudder loop was based on the Lagrange equation and the contact model of revolute joint clearance. Results indicated that rudder angle error, contact force, and impact frequency non-linearly increased along with the increase of motor speed. The increment of joint clearance caused increased rudder angle error and contact force, but a decreased impact frequency. An increase in contact surface roughness decreased the contact force and exerted insignificant effects on rudder angle and impact frequency. To verify the dynamic model, a dynamic characteristic test rig of rudder loop was established. This study can improve the dynamic analysis accuracy of the rudder loop with clearance and provide a solid theoretical basis for solving the high-precision control of the discontinuous structure.

This study evaluates hydrology and hydrological extremes under future climate change scenarios. The climate change scenarios were developed from multiple Global Circulation Models (GCMs), Representative Concentration Pathway (RCPs) scenarios, and statistical downscaling techniques. The hydrological model, Soil Water Assessment Tool (SWAT), was calibrated and validated using the Differential Split-Sample (DSS), where the observed period was divided into relatively 'dry' and 'wet' periods based on observed streamflow. This was to ensure hydrological model robustness simulating contrasting climate conditions. The model was also calibrated and validated at the multi-gauges of the watershed. The multi-model ensemble and single-climate model simulations were used to quantify changes in hydrology and hydrological extremes under future climate scenarios. Future climate change scenarios revealed a reduction in precipitation (in the order of -9.1% to 4.9%) and a consistent increase in maximum temperature (0.34℃ to 4.10℃) and minimum temperature (-0.15 ℃ to 3.7℃) in different climate model simulations. The climate change scenarios triggered a reduction of surface runoff and streamflow and a moderateincrease in evapotranspiration. A decrease in high flow (Q5) and low flow (Q95) was projected from future climate change scenarios. A higher reduction of low flow and annual minimum flow is also simulated in future climate scenarios. Whereas an increase in annual maximum flow is simulated in climate change scenarios developed from the RCP8.5 emission scenario. The study suggests optimal water management structures which can reduce the effect of change in high and low flows.

T-cell acute lymphoblastic leukemia (T-ALL) represents an area of high unmet medical needs. Once relapsed, patients have limited treatment options and usually a poor prognosis. T-ALL antigens such as CD7 is extensively expressed in normal T cells and natural killer (NK) cells, and extending the success of CAR-T therapy to T cell malignancies was challenged by CAR-T cell fratricide, the high production cost, long lagging time and potential product contaminations. GC027 is an “off-the-shelf” allogeneic CD7 targeted CAR-T therapeutic product for T cell malignancies. It demonstrated superior cell expansion and anti-leukemia efficacy in mouse xenograft model. In our previous study, we observed promising efficacy result in the first two r/r T-ALL patient treated with GC027. Deep and durable response in these two patients suggests the potential of a “off-the-shelf” allogeneic CAR-T product as a promising standalone therapy. In the expanded study, 11 out of 12 patients had extensive GC027 cell expansion, rapid eradication of T-lymphoblasts, and reached complete response within 1-month post infusion. At data cut-off of Nov. 30, 2022, 1 patient had progression free survival of > 3 years. With manageable toxicity profile, GC027 demonstrated superior clinical efficacy and durability in T cell malignancies.

Objective
The crash cesarean section (CS), which keeps extremely life-threatening to maternals or fetus, seems to be performed within adequate time horizon for the avoidance of negative feto-maternal denouement. The effective and vigilant technique of anesthesia remains vital for crash cesarean delivery. This study, hence, aims to validate the impact of various anesthesia tactics on the maternal as well as neonatal outcomes.
Method
This was a retrospective cohort study of parturient with the indication for crash CS with the assistance of general or neuraxial anesthesia during the period of January 2015 and July 2021 in our institution. The 1min Apgar score as primary outcome was documented. Secondary outcomes composing 5 min Apgar score, DDI, OAII, duration of operation, length of hospitalization, height and weight of newborn, use of vasopressors, blood loss were also measured.
Results
Of the total 536 subjects incorporated in the analysis, 337 crash CS were performed under general anesthesia (GA), 137 under epidural anesthesia (EA) and 65 under combined spinal-epidural anesthesia (CSE), respectively. The Apgar score of 1 min and 5 min in newborn receiving general anesthesia were lower than those under intraspinal anesthesia and no difference was found between EA and CSEA. The decision-to-delivery interval (DDI) of parturients under GA, EA, and CSE was 7[6,7], 6[6,7], and 14[11.5,20.5], respectively. DDI as well as decision to incision interval (DII) of GA and EA were shorter than CES, among which there was a similarity in DDI and DII between GA and EA. Compared to GA, the onset of anesthesia to incision interval (OAII) of intraspinal anesthesia was extended significantly. The birth height and weight of neonates from EA seem to be superior to GA.
Conclusion
Epidural anesthesia did not exploited negative impact on neonatal and maternal outcomes as compared to general anesthesia and could be utilized as an alternative to general anesthesia in crash cesarean section; in addition, the DDI of crash cesarean section could be achieved within 15 minutes under general or epidural anesthesia in our institution.

This experiment was conducted to investigate the effect of dried Leucaena (Leucaena leucocephala) and cassava (Manihot esculenta) leaves on feed intake, milk production, and milk composition of Holstein Friesian x Ankole crossbred cows. Three cows in early lactation, with initial milk production of 4 ± 1.20 kg/day and 359 ± 24 kg average live body weight, were randomly assigned to the experimental diet in a 3x3 Latin square design. Three 15-day experimental periods were adopted (1 to 10-day: diet adaptation and 11 to 15-day: data collection). Cows were fed on a freshly chopped Guatemala grass diet supplemented with 1.25 kg DM of brewers’ spent grain (control). The experimental diets were similar to the control diet differing in the presence of dried Leucaena or cassava leaves, both at the inclusion rate of 20% of the basal diet intake. Total dry matter intake, nutrient intake, milk production, and milk composition showed significant variation among treatments. Cows supplemented with dried cassava leaves had higher total dry matter intake and organic matter intake. Leucaena significantly increased (p < 0.001) daily milk production by 15% compared to cassava (3%). Leucaena had a higher milk fat content (38.44 g), while cassava and the control diet had higher milk protein (38.53 and 38.43 g), lactose (56.79 g and 56.111 g), and not-fat solids (102.41 g and 101.27 g). These results indicate that dried Leucaena and cassava leaves can be used as protein supplements for Guatemala grass basal diet for crossbred cows to improve milk production and quality.

Identifying prognostic early brain alterations is crucial for autism spectrum disorder (ASD). Leveraging structural MRI data from 166 ASD and 109 typical developing (TD) toddlers and controlling for brain size, we found that, compared to TD, ASD toddlers showed larger or thicker lateral temporal regions; smaller or thinner frontal lobe and midline structures; larger callosal subregion volume; and smaller cerebellum. Most of these differences were replicated in an independent cohort of 38 ASD and 37 TD toddlers. Moreover, the identified brain alterations were related to ASD symptom severity and cognitive impairments at intake, and, remarkably, they improved the accuracy for predicting later language outcome beyond intake clinical and demographic variables. In summary, brain regions involved in language, social, and face processing were altered in ASD toddlers. These early-age brain alterations may be the result of dysregulation in multiple neural processes and stages and are promising prognostic biomarkers for future language ability.
