Rights and Responsibilities of Non-Muslim Citizens in Pakistan:
Authors: Riaz Ahmad Saeed  , Aftab Khan Hafiz Muhammad
Published: January 2024

Every corner of the Holy Prophet's (PBUH life illuminates the lamp of guidance. One of the most important attributes of his Seerah is being a ruler. The principles you left as a ruler are still useful in the modern era. As ruler of Madina, he gave the status of a state which was a confederation of units with Socio- political autonomy. He made various covenants for the development and defence of the state of Madina. One of the most important of which is remembered as the charter of Madina (Methaq-e- Madina).

Part of the charter of Madina sets out the rights and duties of all citizens including non-Muslims. And it specifically mentions the Jewish tribes who have lived here for a long time and almost occupied the financial resources of Medina. Therefore, there was a need to determine their rights and duties in an Islamic state, so that they would play a vital role in the development and stability of the State. Under the Madina Seerah charter, they were guaranteed protection of all kinds of religious, political and social rights and liberties. The Madina charter is in fact, an important document for a peaceful society and is also a fundamental part of his political and constitutional struggle.  This study is an effort to explore the Charter of Madiana for religious minorities’ rights and duties in the context of Pakistan as an Islamic State. The analytical research methodology will be adopted in this study to reach the conclusion.

In view of the charter of Madina, there are some similarities between the State of Madina and Pakistan. The constitution of Pakistan also guarantees that every citizen has the right to practice any religion. Therefore, the dissertation under investigation is important as it will provide an opportunity to be aware of the rights and duties of non-Muslims citizens living in Pakistan in the light of the charter of Madina.

Keywords: Madina Charter, non-Muslims, rights and duties, Pakistan, reflections

Triad of Art Interpretation
Authors: Yakovleva Elena Ludvigovna
Published: January 2024

the object of the study is the problem of art interpretation. In the process of interpreting the work, three codes intersect: from the sender, in the message and from the addressee. Each of the three codes is unique and intricate, which entails the complexity of the interpretation process and gives rise to many interpretations of the message. Thus, the artistic text embodying the idea is filled with symbols and carries the author’s messages. The above leads to the appearance of an aura felt by the addressee. When writing a work of art, the author encodes in it not only his own self and existential situations, but also embodies the invisible with the help of intuition. The addressee, immersed in a work of art, transfers the artistic world to his life, which helps him to understand himself. The listed coded systems contribute to the emergence of many interpretations.

In this work, a numerical simulation was used to investigate the impact that the length and positioning of the heat source had on the mixed convection opposing flow that occurred within the horizontal channel that included an open parallelogram cavity. When the wall being heated is facing away from the direction of the incoming force. Different placements of the heat source along the cavity's sidewalls were explored, with the length of the heat source set at (ε) (0.25<ε<1). The cool, steady-speed air came in through the sides of the canal. All other walls are adiabatic, while the vertical walls on the inflow and outflow sides are isothermal. The governing equations were solved using the finite element technique. For several different values of the Richardson number (Ri=0.1-100), we estimated the flow and heat fields. While the Prandtl number is held at 0.71 and the Reynolds number is maintained at 100. The average Nusselt values, as well as the findings of the flow and temperature fields, were reported. The findings demonstrate that both the Richardson number (Ri) and the distance from the heat source (ε) positively affect the heat transfer rate. It was also determined that for all Richardson numbers, the highest average Nusselt number is attained at the higher portion of the right wall of the hollow.
Investigation into Impedance Measurements for Rapid Capacity Estimation of Lithium-ion Batteries in Electric Vehicles
Authors: Zhao Xiaoyu , Wang Zuolu , Li Eric , Miao Haiyan
Published: January 2024

With the dramatic increase in electric vehicles (EVs) globally, the demand for lithium-ion batteries has grown dramatically, resulting in many batteries being retired in the future. Developing a rapid and robust capacity estimation method is a challenging work to recognize the battery ageing level on service and provide regroup strategy of the retied batteries in secondary use. There are still limitations on the current rapid battery capacity estimation methods, such as direct current internal resistance (DCIR) and electrochemical impedance spectroscopy (EIS), in terms of efficiency and robustness. To address the challenges, this paper proposes an improved version of DCIR, named pulse impedance technique (PIT), for rapid battery capacity estimation with more robustness. First, PIT is carried out based on the transient current excitation and dynamic voltage measurement using the high sampling frequency, in which the coherence analysis is used to guide the selection of a reliable frequency band. The battery impedance can be extracted in a wide range of frequency bands compared to the traditional DCIR method, which obtains more information on the battery capacity evaluation. Second, various statistical variables are used to extract ageing features and Pearson correlation analysis is applied to determine the highly correlated features. Then a linear regression model is developed to map the relationship between extracted features and battery capacity. To validate the performance of the proposed method, the experimental system is designed to conduct comparative studies between PIT and EIS based on the two 18650 batteries connected in series. The results reveal that the proposed PIT can provide comparative indicators to EIS, which contributes higher estimation accuracy of the proposed PIT method than EIS technology with lower time and cost.

Importância das exportações para as empresas industriais brasileiras
Authors: Guimarães Eduardo Augusto
Published: January 2024

Este estudo examina a importância das exportações para as empresas industriais brasileiras no período 2008-2018, tendo como referência os seus coeficientes de exportação – a razão entre o valor de suas exportações e suas receitas. O estudo utiliza informações não divulgadas da Pesquisa Industrial Anual (PIA) do Instituto Brasileiro de Geografia e Estatística (IBGE). Os resultados, detalhados por setores – divisões e grupos da Classificação Nacional de Atividades Econômicas (CNAE) 2.0, do IBGE –, contemplam também a diferenciação intrassetorial do desempenho das empresas nas divisões e nos grupos industriais. O coeficiente de exportação da indústria de transformação experimentou queda entre 2008 e 2014, e recuperação no período seguinte. Os coeficientes relativos aos diversos setores industriais são diferenciados segundo segmentação que reflete a natureza da produção dos setores – entre os setores que apresentam coeficientes mais elevados, predominam os fabricantes de bens intermediários, particularmente os associados à transformação de matérias-primas agrícolas e minerais. O estudo indica ainda que os setores com coeficientes de exportação mais elevados recorrem pouco aos insumos importados – vale dizer, os setores mais integrados a jusante em cadeias globais de valor são menos integrados a montante.
A Statistical Analysis of Spiral-shaped Wave Patterns in Sunspot Umbrae
Authors: Kang Juhyung , Chae Jongchul , Geem Jooyeon
Published: January 2024

Spiral-shaped wave patterns (SWPs) observed in sunspot umbrae represent the superposition of axisymmetric patterns and nonaxisymmetric patterns of umbral oscillations. These patterns give us physical information about the source of oscillations below the surface. Here we present the statistics of their observational properties determined from the 304 Å line-intensity data obtained with the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory. From the 2013 to 2018 data set, we examined each of the 496 sunspots near the disk center for 2 hr. As a result, we identified 241 SWPs from 140 sunspots, which corresponds to the detection rate of 0.24 per hour in each sunspot. Most of the SWPs had one spiral arm, 48 SWPs had two arms, and only one had three. The oscillation period was estimated at 151 ± 27 s and the lifetime, at 770 ± 250 s, being comparable to those of conventional umbral oscillations. The rotation period of the SWPs was estimated at 190 ± 69 s for the one-armed SWPs and 299 ± 115 s for the two-armed SWPs. We found that the properties of the SWPs have no dependence on hemisphere, latitude, and sunspot size. From the apparent radial speeds of the SWPs and a simple model of wave propagation, we infer that the SWPs may be generated between 2 and 11 Mm below the photosphere with a mean value of about 6 Mm.

The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe, when the supersonic relative motions between dark matter and baryonic overdensities modulate structure formation (z ≳ 10). We study low-mass galaxy formation, including this “stream velocity,” using high-resolution AREPO hydrodynamics simulations and present theoretical predictions of the UV luminosity function (UVLF) and galaxy stellar mass function down to extremely faint and low-mass galaxies (M
UV ≳ −15, 104
M
⊙ ≤ M
* ≤ 108
M
⊙). We show that, although the stream velocity suppresses early star formation overall, it induces a short period of rapid star formation in some larger dwarfs, leading to an enhancement in the faint end of the UVLF at z = 12. We demonstrate that JWST observations are close to this enhanced regime and propose that the UVLF may constitute an important probe of the stream velocity at high redshift for JWST and future observatories.
Three-dimensional GRMHD Simulations of Neutron Star Jets
Authors: Das Pushpita , Porth Oliver
Published: January 2024

Neutron stars and black holes in X-ray binaries are observed to host strong collimated jets in the hard spectral state. Numerical simulations can act as a valuable tool in understanding the mechanisms behind jet formation and its properties. Although there have been significant efforts in understanding black hole jets from general relativistic magnetohydrodynamic (GRMHD) simulations in recent years, neutron star jets still remain poorly explored. We present the results from three-dimensional GRMHD simulations of accreting neutron stars with oblique magnetospheres for the very first time. The jets in our simulations are produced due to the anchored magnetic field of the rotating star in analogy with the Blandford–Znajek process. We find that for accreting stars, the star–disk magnetic field interaction plays a significant role, and as a result, the jet power becomes directly proportional to

Φ

jet

, where Φjet is the open flux in the jet. The jet power decreases with increasing stellar magnetic inclination, and finally, for an orthogonal magnetosphere, it reduces by a factor of ≃2.95 compared to the aligned case. We also find that in the strong propeller regime, with a highly oblique magnetosphere, the disk-induced collimation of the open stellar flux preserves parts of the striped wind, resulting in a striped jet.
A Fokker–Planck Framework for Studying the Variability of the Magnetic Field Direction in the Alfvénic Streams of the Solar Wind
Authors: Bian N. H. , Li Gang
Published: January 2024

Turbulent rotations of the magnetic field vector are observed in the Alfvénic streams of the solar wind where the magnetic field strength remains close to a constant. They can lead to reversals of the radial magnetic field component or switchbacks. It is not ruled out from the data that the rotations are divisible into the sum of small random angular deflections. In this work, we develop tools aimed at the analysis of the one-point statistical properties of the directional fluctuations of the magnetic field vector in the solar wind. The angular fluctuations are modeled by a drift-diffusion process which admits the exponential distribution as steady-state solution. Realizations of the stochastic process are obtained by solving the corresponding Langevin equation. It is shown that the cumulative effects of consecutive small-angle deflections can yield frequent reversals of the magnetic field vector even when the concentration parameter of the directional data is large. The majority of the rotations are associated with nearly transverse magnetic field fluctuations in this case.
Complete mitochondrial genome of Plecia longiforceps Duda, 1933 (Diptera, Bibionidae) and its implications for the evolution of mass outbreaks in flies
Authors: Jung Seunghun , Kim Sangil , Shin Seunggwan
Published: January 2024

Over the past decade, the prevalence of mass outbreaks involving non-native insects has sparked concerns about their potential negative impact on human inhabited areas and local environments. Plecia longiforceps Duda, 1933 (Diptera, Bibionidae) was recently recognized as an invasive pest in South Korea, causing public nuisance through mass outbreaks in the Seoul Metropolitan Area during early summer. In this study, we present the first complete mitochondrial genome of Plecia longiforceps, generated from the PacBio HiFi long-read sequencing data. Notably, the length of the circular genome is found to be larger than any annotated reference sequences of mitochondrial genomes for the infraorder Bibionomorpha, which is attributable to an unusually long A+T rich control region. We conducted a phylogenetic analysis of Bibionomorpha, leveraging all mitochondrial genome data sequenced to date, to elucidate relationships among genera within Bibionidae. Our resulting phylogeny of Bibionomorpha recovered a strong monophyly of the family Bibionidae and its three subfamilies: Bibioninae (Bibio + Dilophus), Hesperininae (Hesperinus + Penthetria), and Pleciinae (Plecia), corroborating the recently proposed taxonomic classification system of Bibionidae. Furthermore, we discuss evolutionary trends within Bibionidae based on our well-supported higher relationships of the superfamily Bibionoidea.

Published: January 2024

In the search for insects as biological control agents for the water primrose, the delphacid Pissonotus paraguayensis (Delphacidae) was found on Ludwigia grandiflora subsp. hexapetala (Onagraceae) in a wetland of Central East Argentina. The morphology of the unknown females (brachypterous and macropterous) and immature stages are described and illustrated. Adults and nymphs were collected in wetlands of Del Plata River Basin, from Buenos Aires to the northeastern part of Argentina. A rearing methodology was developed to perform biological studies. Both winged forms and structural features of the female genitalia are described for the first time at the genus level. Eggs and immature stages are described and keyed; fifth nymphal instars may be easily recognised by the yellowish colouration, blackish on dorsal of head, thorax and abdomen with conspicuous yellowish pits, ventrally only darkened on base of frons extended to lower level of eyes and dorsal surface of antennomeres I and II, and legs with distinctive black marks at femoro-tibial joint and apex. The geographical distribution is updated, expanding its range into Argentina, making Buenos Aires the southernmost limit of the genus in America. Biological information of the species is also reported here: life cycle, fecundity, oviposition behaviour, and host plant. Field observations showed that P. paraguayensis breeds, feeds, and causes damage to L. g. subsp. hexapetala. This delphacid presents a certain degree of specificity to the Ludwigia species in the Jussiaea section in host specificity tests. More studies are required to test this species as a potential biological control agent.
Analysis of noise distributions at heliports and vertiports: A guide for site selection and land use planning
Authors: Ison David
Published: January 2024

Purpose: The purpose of this study was to examine the noise profiles of helicopters and eVTOLs at heliports and vertiports in order to support site planning and the development of local land-use compatibility guidelines. Design/methodology/approach: This study used existing helicopter and eVTOL sound profiles to develop noise distribution contours for heliports and vertiports. This study collected noise data from available studies on helicopters and eVTOLs. This data was then entered into dBmap noise mapping tool to develop noise maps for helicopters and eVTOLs. Three air transit facility configurations for each aircraft category were analyzed: open (unobstructed), urban, and rooftop. Two additional vertiport configurations were created by overlaying building and noise data with Google Earth imagery. Noise data was entered into dBmap for processing. Noise contours were mapped for three configurations for both aircraft categories.Findings: Key observations from the noise distribution analysis showed that open (unobstructed) facility configurations have even noise distributions for both eVTOLs and helicopters. Noise maps for urban locations showed areas of attenuation and asymmetrical patterns due to the interactions of sound waves with surrounding buildings. An analysis of a rooftop installation of a heliport or vertiport provided some noise mitigation advantages. Noise contour distributions closely matched those outlined in previous research; however, the sound intensities modeled in this study were lower than indicated in exigent research. Assessments were also conducted for real-world sites with potential future use as vertiports in Seattle, Washington, and Chicago, Illinois.Practical Implications: This study suggests that current land use compatibility guidance may be inadequate for rotorcraft and eVTOL operations. Findings suggest the development of symmetrical noise-impact zones centered around heliports and vertiports. Examples of these zones are outlined, and recommendations for future research are provided. Local planners can use the data from this study to make educated choices about the siting of heliports and vertiports. Additionally, the findings can assist planners in the development of zoning and land use compatibility standards.Social Implications: Land use compatibility standards for heliports and vertiports will help ensure a synergistic relationship between local communities and these air transit facilities. The data from this study can also help protect individuals from excessive noise and annoyance.Originality/value: This study is one of the few on this topic and the only known research on noise distributions of helicopters and eVTOLs with a particular focus on land use compatibility
Visual Outcomes and Safety of a Refractive Corneal Inlay for Presbyopia: One-Year Results
Authors: Kohnen Thomas , Lwowski Christoph , Böhm Myriam , Hemkeppler Eva , Jandewerth Tyll
Published: January 2024

Purpose:

To determine the visual outcomes and safety 12 months after implantation of the Presbia Flexivue Microlens refractive corneal inlay.

Methods:

In this prospective, non-randomized trial, 22 patients with a mean age of 52.54 ± 2.86 years were implanted with the Flexivue Microlens refractive corneal inlay in the non-dominant eye at the Department of Ophthalmology, Goethe University, Frankfurt, Germany. Corrected near, intermediate, and distance (CNVA, CIVA, and CDVA) visual acuity and uncorrected near, intermediate, and distance (UNVA, UIVA, and UDVA) visual acuity, manifest refraction, subjective quality of vision, endothelial cell count, and contrast sensitivity were measured 1 day, 1 week, and 1, 3, 6, and 12 months postoperatively.

Results:

For binocular CDVA, no patient lost two or more lines and 30% lost only one line at the 12-month visit. In the eye that had surgery, 85% of the patients lost two or more lines of UDVA, which was statistically significant. Sixty-five percent of the patients gained one or more lines in binocular UIVA, and 80% achieved 20/40 or better in DCIVA. UNVA showed a statistically significant improvement, with 90% of the patients achieving 20/40 or better 12 months after implantation. A total of 85% gained two or more lines in binocular UNVA.

Conclusions:

This refractive corneal inlay showed an improvement in binocular UNVA, UIVA, CNVA, and CIVA, whereas binocular CDVA and UDVA were not statistically affected.

Three-Month Clinical Outcomes to Correct Myopia or Myopic Astigmatism Using a Femtosecond Laser for Lenticule Creation With Automated Centration and Cyclotorsion Compensation
Authors: Yoon Hyosung , Magnago Thomas , Yeom Donjg-Ju
Published: January 2024

Purpose:

To individually evaluate the clinical outcomes for right and left eyes in the first 3 months after laser-assisted lenticule extraction for myopia and myopic astigmatism with the use of the new ATOS femtosecond laser system (Smart-Sight; SCHWIND eye-tech-solutions).

Methods:

A total of 331 eyes from 168 patients (166 right eyes and 165 left eyes) consecutively treated with SmartSight lenticule extraction were retrospective analyzed after a 3-month follow-up period. Patients' mean age was 26 ± 6 years (range: 18 to 47 years) and mean preoperative spherical equivalent (SEQ) was −5.07 ± 1.92 diopters [D] (range: −1.50 to −11.25 D) with a mean astigmatism of −1.04 ± 0.85 D (range: 0.00 to −4.00 D). At 3 months of follow-up, visual acuity, SEQ and cylinder, safety index, efficacy index, corneal higher order aberrations, and intraocular pressure (IOP) were analyzed. Furthermore, refractive and visual outcomes were also analyzed for the right and left eyes individually. All lenticule extraction treatments were performed with the SmartSight treatment method of the SCHWIND ATOS femtosecond laser.

Results:

At 3 months after surgery, mean SEQ was −0.12 ± 0.19 D and 98% of eyes were within ±0.50 D of the SEQ. All eyes were within ±1.00 D of the SEQ. Astigmatism of 0.50 D or less was achieved in 99% of eyes. The change in Snellen lines (difference between preoperative corrected distance visual acuity and postoperative uncorrected distance visual acuity) showed a gain of one or more lines in 13% and in 85% of the eyes the same was achieved. There was a loss of one or more lines at 3 months of follow-up in 1.6%. The safety index was 1.03 and efficacy index was 1.02. No significant difference between the right and left eyes was found.

Conclusions:

The 3-month follow-up data show that SmartSight treatment for correction of myopia and myopic astigmatism with the SCHWIND ATOS is a safe, efficient, and accurate procedure. It provided excellent results in terms of visual recovery, predictability, and higher order aberrations.

Bilateral Combined Rhegmatogenous and Tractional Retinal Detachments Due to Persistent High-Titer Syphilis
Authors: Rahman Effie Z. , Beck Kinley D. , Wong Robert W. , Sohn Jeong-Hyeon , Diaz-Rohena Roberto D. , Harper C. Armitage
Published: January 2024

A 23-year-old man developed bilateral rhegmatogenous retinal detachments secondary to high-titer ocular syphilis. The patient's titer increased four-fold after completing a 14-day course of intravenous penicillin (IVP). He underwent bilateral pars plana vitrectomy with silicone oil fill in both eyes. In this article, the authors propose an updated treatment method for patients with advanced ocular syphilis that includes oral doxycycline for 30 days following 14 days of IVP to optimally minimize the patient's infectious burden. Following surgery and this new treatment regime, this patient's best-corrected visual acuity 10 weeks postoperatively measured 20/50 in the right eye and 20/30 in the left eye. This case highlights a rare but devastating complication of ocular syphilis. We suggest the addition of oral doxycycline to IVP for patients with syphilis titers ≥ 1:256, HIV co-infection, and presence of posterior retinitis.

Stability analysis and numerical simulation of rabies spread model with delay effects
Authors: Nurdiansyah Muhammad Rifqy Adha , Kasbawati  , Toaha Syamsuddin
Published: January 2024

In this article, a delay differential equations model is constructed to observe the spread of rabies among human and dog populations by considering two delay effects on incubation period and vaccine efficacy. Other parameters that affect the spread of rabies are also analyzed. Using the basic reproduction number, it is shown that dog populations and the two delays gives a significant effect on the spread of rabies among human and dog populations. The existence of two delays causes the system to experience Transcritical bifurcation instead of Hopf bifurcation. The numerical simulation shows that depending only on one control method is not enough to reduce or eradicate rabies within the dog populations; instead, it requires several combined strategies, such as increasing dog vaccinations, reducing contact with infected dogs, and controlling puppies' birth. The spread within the human population will be reduced if the spread within the dog population is reduced.
Adjusting for Confounders in Outcome Studies Using the Korea National Health Insurance Claim Database: A Review of Methods and Applications
Authors: Han Seung Jin , Kim Kyoung Hoon
Published: January 2024

Objectives: Adjusting for potential confounders is crucial for producing valuable evidence in outcome studies. Although numerous studies have been published using the Korea National Health Insurance Claim Database, no study has critically reviewed the methods used to adjust for confounders. This study aimed to review these studies and suggest methods and applications to adjust for confounders.Methods: We conducted a literature search of electronic databases, including PubMed and Embase, from January 1, 2021 to December 31, 2022. In total, 278 studies were retrieved. Eligibility criteria were published in English and outcome studies. A literature search and article screening were independently performed by 2 authors and finally, 173 of 278 studies were included.Results: Thirty-nine studies used matching at the study design stage, and 171 adjusted for confounders using regression analysis or propensity scores at the analysis stage. Of these, 125 conducted regression analyses based on the study questions. Propensity score matching was the most common method involving propensity scores. A total of 171 studies included age and/or sex as confounders. Comorbidities and healthcare utilization, including medications and procedures, were used as confounders in 146 and 82 studies, respectively.Conclusions: This is the first review to address the methods and applications used to adjust for confounders in recently published studies. Our results indicate that all studies adjusted for confounders with appropriate study designs and statistical methodologies; however, a thorough understanding and careful application of confounding variables are required to avoid erroneous results.
