Published: July 2023

China’s Belt and Road Initiative (BRI), introduced in 2013, has been strongly supported by various Free Trade Zones (FTZs). The pilot Shanghai Free Trade Zone (SFTZ) received much attention after a major reform in 2019. Malaysia’s enterprises consist of young and infant industries. Hence, this study has aimed to provide insights into the awareness among Malaysia’s enterprises towards SFTZ. In addition, hidden opportunities and challenges will be discussed in detail and further enlighten the concerns of Malaysian enterprises. A purposive sampling method has been applied to select the participants for the five focus group discussions. The results indicated a gap between government practices and industry players regarding the opportunities, challenges, and prospects in the SFTZ. Malaysia is expected to benefit from the SFTZ through comparative advantages in certain industries, with its talent, and through unique products with intellectual property rights. At the same time, Malaysian businesses have remained constrained by several obstacles, such as lack of information, exit policies and differences in regulations. Although MATRADE has stepped in as a bridge between local and Shanghai enterprises, more is needed to be done.

The historical background in the interpretation of Nasr Hamid "Abu Zaid", a critical analytical study
Authors: سلطان حمزة , سلمان محمد
Published: July 2023

The issue of historicity is one of the most important sensitive topics, which still raises a lot of controversy among currents of contemporary Islamic thought, between those who see it as a destructive weapon that leaves nothing of religion, and those who see it as a new and alternative mechanism for all mechanisms of Islamic jurisprudence, in all frameworks and levels, whether belief or jurisprudence. .The historical tendency presents itself as a method for understanding the text and reading the language within its historical context, just as it is a method for understanding the historicity of laws and rulings. In the sense of believing that the language when used by the speaker remains under the influence of the nature of the historical circumstance in which it came, that the dispute over this saying is not between the modernists and the traditionalists only, but between the modernists themselves, for they are between those who accept it as a methodology in the Qur’an and Sunnah without any difference, and between those who accept it in the Sunnah only ,

Scientific approach to improving the mechanical properties of metal products during their additive growth
Authors:   Kabaldin Yu.G. Anosov M.S. Kolchin P.V. Shatagin D.A.
Published: July 2023

The reasons for the low performance of products made by additive growing under extreme operating conditions are investigated. The formation of defects in the crystalline structure at the macrolevel at the interface between the formed layers and the occurrence of high internal stresses are established, which should be considered as the main factor in reducing the mechanical properties of metals formed by 3D printing. To improve the mechanical properties of metals, additional heat treatment is necessary.

The New Virtuality: A Video Essay on the Disappearing Differences Between Real and Unreal
Authors: Ng Jenna
Published: July 2023

This video essay explores the implications of highly realistic images that appear, interact and socialise with human users, often seemingly “live” in real-time. Through readings of film and media theory, archival research, textual readings (across paintings, digital art, cinema, performance, VR, apps and architecture) and media archaeology, the essay argues for virtuality as a multi-paradoxical and discombobulating vacillation: believed yet disbelieved; manipulated yet recognisable; realistic yet fake. This renewed understanding of the virtual also signals the pliability of post-truth and its concomitant challenges to frameworks of disbelief, reliability and certainty. It constitutes the new battleground for understanding the politics of current and future realities and histories.

Danggui Sini decoction is a traditional Chinese medicine preparation commonly used in the treatment of blood stasis syndrome through a mechanism yet to be defined. Therefore, we have explored its mechanism of action by combining pharmacology and gut microbiota analysis. To this end, female Sprague-Dawley rats were divided into 5 groups, including the control group, the acute blood stasis group, the Danshen tablet-treated group, the low-dose Danggui Sini decoction group, and the high-dose Danggui Sini decoction group. Danggui Sini decoction led to a significant reduction in the changes in the whole blood viscosity and plasma viscosity of rats with acute blood stasis syndrome, improved the coagulation function and cardiopulmonary pathological injury, upregulated the plasma 6-keto prostaglandin F1α and endothelial nitric oxide synthase, and downregulated thromboxane B2 and endothelin-1. The high throughput 16S rRNA gene sequencing results showed that Danggui Sini decoction reduced the number of pathogenic proteobacteria, significantly reduced erysipelas and suzericella, and increased the beneficial bacteria Roche, effectively improving the status of intestinal flora disorder in acute blood stasis rats. The Spearman correlation analyses showed that there was a close correlation between intestinal flora distribution and changes in blood stasis-related biochemical indices. In addition, network pharmacological analysis showed that the epidermal growth factor receptor, tumor protein p53, signal transducer and activator of transcription 3, vascular endothelial growth factor A, and hypoxia-inducible factor 1-alpha were the core targets of Danggui Sini decoction in alleviation of blood stasis. Further genetic ontological and pathway enrichment analyses suggested that the therapeutic effect of Danggui Sini decoction on blood stasis involved the lipid and atherosclerosis pathways, advanced glycation end-product-receptor for advanced glycation end-product signaling pathways in diabetic complications, fluid shear stress and atherosclerosis pathways, and hypoxia-inducible factors, 1-alpha signaling pathway, phosphatidylinositol 3-kinase- protein kinase B signaling, and other pathways. These results are helpful in understanding the mechanism by which Danggui Sini decoction improves blood stasis and provide a reference for further research.

The spatial distribution and evolution of gas in the inner 10 au of protoplanetary disks form the basis for estimating the initial conditions of planet formation. Among the most important constraints derived from spectroscopic observations of the inner disk are the radial distributions of the major gas phase constituents, how the properties of the gas change with inner disk dust evolution, and how the chemical abundances and excitation conditions are influenced by the high-energy radiation from the central star. We present a survey of the radial distribution, excitation, and evolution of inner disk molecular hydrogen (H2) obtained as part of the Hubble Space Telescope-ULLYSES program. We analyze far-UV spectroscopy of 71 (63 accreting) pre-main-sequence systems in ULLYSES DR5 to characterize the H2 emission lines, H2 dissociation continuum emission, and major photochemical/disk evolution driving the UV emissions (Lyα, UV continuum, and C iv). We use the widths of the H2 emission lines to show that most fluorescent H2 arises between 0.1 and 1.4 au from the parent star, and show positive correlations of the average emitting radius with the accretion luminosity and with the dust disk mass. We find a strong correlation between H2 dissociation emission and both the accretion-dominated Lyα luminosity and the inner disk dust clearing, painting a picture where water molecules in the inner 3 au are exposed to and dissociated by strong Lyα emission as the opacity of the inner disk declines with time.

Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument (DESI), leading to a fourfold increase in the number of known quasars. High-accuracy quasar classification is essential to tighten constraints on cosmological parameters measured at the highest redshifts DESI observes (z > 2.0). We present spectral templates for identification and redshift estimation of quasars in the DESI Year 1 data release. The quasar templates are comprised of two quasar eigenspectra sets, trained on spectra from the Sloan Digital Sky Survey. The sets are specialized to reconstruct quasar spectral variation observed over separate yet overlapping redshift ranges and, together, are capable of identifying DESI quasars from 0.05 < z < 7.0. The new quasar templates show significant improvement over the previous DESI quasar templates regarding catastrophic failure rates, redshift precision and accuracy, quasar completeness, and the contamination fraction in the final quasar sample.
A Comprehensive Study on the Relation between the Metal Enrichment of Ionized and Atomic Gas in Star-forming Galaxies

We study the relation between the metallicities of ionized and atomic gas in star-forming galaxies at z = 0–3 using the Evolution and Assembly of GaLaxies and their Environments (EAGLE) cosmological, hydrodynamical simulations. This is done by constructing a dense grid of sight lines through the simulated galaxies and obtaining the star formation rate- and H i column density-weighted metallicities, Z
SFR and Z
H I, for each sightline as proxies for the metallicities of ionized and atomic gas, respectively. We find Z
SFR ≳ Z
H I for almost all sight lines, with their difference generally increasing with decreasing metallicity. The stellar masses of galaxies do not have a significant effect on this trend, but the positions of the sight lines with respect to the galaxy centers play an important role: the difference between the two metallicities decreases when moving toward the galaxy centers, and saturates to a minimum value in the central regions of galaxies, irrespective of redshift and stellar mass. This implies that the mixing of the two gas phases is most efficient in the central regions of galaxies where sight lines generally have high column densities of H i. However, a high H i column density alone does not guarantee a small difference between the two metallicities. In galaxy outskirts, the inefficiency of the mixing of star-forming gas with H i seems to dominate over the dilution of heavy elements in H i through mixing with the pristine gas. We find good agreement between the available observational data and the Z
SFR–Z
H I relation predicted by the EAGLE simulations. Though, observed regions with a nuclear starburst mode of star formation appear not to follow the same relation.

Studying compact-star binaries and their mergers is integral to determining progenitors for observable transients. Today, compact-star mergers are typically studied via state-of-the-art computational fluid dynamics codes. One such numerical technique, smoothed particle hydrodynamics (SPH), is frequently chosen for its excellent mass, energy, and momentum conservation. The natural treatment of vacuum and the ability to represent highly irregular morphologies make SPH an excellent tool for the study of compact-star binaries and mergers. For many scenarios, including binary systems, the outcome of simulations is only as accurate as the initial conditions. For SPH, it is essential to ensure that the particles are distributed regularly, representing the initial density profile but without long-range correlations. Particle noise in the form of high-frequency local motion and low-frequency global dynamics must be damped out. Damping the latter can be as computationally intensive as the actual simulation. We discuss a new and straightforward relaxation method, halted-pendulum relaxation (HPR), to remove global oscillation modes of SPH particle configurations. In combination with effective external potentials representing gravitational and orbital forces, we show that HPR has an excellent performance in efficiently relaxing SPH particles to the desired density distribution and removing global oscillation modes. We compare the method to frequently used relaxation approaches and test it on a white dwarf binary model at its Roche-lobe overflow limit. We highlight the importance of our method in achieving accurate initial conditions and its effect on achieving circular orbits and realistic accretion rates when compared with other general relaxation methods.

We explored the parsec-scale nuclear regions of a sample of radio-loud narrow-line Seyfert 1 galaxies (NLSy1s) using the VLBI Exploration of Radio Astrometry wideband (at a recording rate of 16 Gbps) polarimetry at 22 and 43 GHz. Our targets include 1H 0323+342, SBS 0846+513, PMN J0948+0022, 1219+044, PKS 1502+036, and TXS 2116-077, which are all known to exhibit γ-ray emission indicative of possessing highly beamed jets similar to blazars. For the first time, we unambiguously detected Faraday rotation toward the parsec-scale radio core of NLSy1s, with a median observed core rotation measure (RM) of 2.7 × 103 rad m−2 (or 6.3 × 103 rad m−2 for redshift-corrected). This level of RM magnitude is significantly larger than those seen in the core of BL Lacertae objects (BLOs; a dominant subclass of blazars), suggesting that the nuclear environment of NLSy1s is more gas-rich than that in BLOs. Interestingly, the observed parsec-scale polarimetric properties of NLSy1s (low core fractional polarization, large core RM and jet–EVPA misalignment) are rather similar to those of flat-spectrum radio quasars (FSRQs). Our results are in accordance with the scenario that NLSy1s are in an early stage of active galactic nucleus evolution with their central black hole masses being smaller than those of more evolved FSRQs.

Type II solar bursts are radio signatures of shock waves in the solar corona driven by solar flares or coronal mass ejections (CMEs). Therefore, these bursts present complex spectral morphologies in solar dynamic spectra. Here, we report meter–decameter radio observations of a type II burst on 2014 July 25 made with the Ukrainian radio telescopes UTR-2 (8.25–33 MHz) and GURT (8.25–78 MHz). The burst demonstrates fundamental and harmonic components, band splitting, a herringbone structure, and a spectral break. These specific spectral features, observed jointly in a single type II burst, are rarely detected. To contribute to our understanding of such puzzling type II events, we carried out a detailed analysis of the recorded type II dynamic spectrum. In particular, the herringbone pattern has been exploited to study electron density turbulence in the solar corona. We calculated the power spectral densities of the flux variations in selected herringbones. The spectral index is in the range of α = −1.69 to −2.00 with an average value of −1.897, which is slightly higher than the Kolmogorov spectral index of −5/3 for fully developed turbulence. We also recognized that the second type II burst consists of three drifting lanes. The lane onset times coincide with the spectral break in the first type II burst. We regard that the CME/shock passage through a streamer caused the spectral break and triggered the multilane type II radio emission. Thus, we support one of the proposed scenarios for type II burst occurrence as being the result of CME/shock–streamer interaction.

Magnetic reconnection is an important source of energetic particles in systems ranging from astrophysics to the laboratory. The large separation of spatiotemporal scales involved makes it critical to determine the minimum physical model containing the necessary physics for modeling particle acceleration. By resolving the energy gain from ideal and nonideal magnetohydrodynamic electric fields self-consistently in kinetic particle-in-cell simulations of reconnection, we conclusively show the dominant role of the nonideal field for the early stage of energization known as injection. The importance of the nonideal field increases with magnetization, guide field, and in three dimensions, indicating its general importance for reconnection in natural astrophysical systems. We obtain the statistical properties of the injection process from the simulations, paving the way for the development of extended MHD models capable of accurately modeling particle acceleration in large-scale systems. The novel analysis method developed in this study can be applied broadly to give new insight into a wide range of processes in plasma physics.
SBI++: Flexible, Ultra-fast Likelihood-free Inference Customized for Astronomical Applications

Published: July 2023

Flagship near-future surveys targeting 108–109 galaxies across cosmic time will soon reveal the processes of galaxy assembly in unprecedented resolution. This creates an immediate computational challenge on effective analyses of the full data set. With simulation-based inference (SBI), it is possible to attain complex posterior distributions with the accuracy of traditional methods but with a >104 increase in speed. However, it comes with a major limitation. Standard SBI requires the simulated data to have characteristics identical to those of the observed data, which is often violated in astronomical surveys due to inhomogeneous coverage and/or fluctuating sky and telescope conditions. In this work, we present a complete SBI-based methodology, SBI

++
, for treating out-of-distribution measurement errors and missing data. We show that out-of-distribution errors can be approximated by using standard SBI evaluations and that missing data can be marginalized over using SBI evaluations over nearby data realizations in the training set. In addition to the validation set, we apply SBI

++
to galaxies identified in extragalactic images acquired by the James Webb Space Telescope, and show that SBI

++
can infer photometric redshifts at least as accurately as traditional sampling methods—and crucially, better than the original SBI algorithm using training data with a wide range of observational errors. SBI

++
retains the fast inference speed of ∼1 s for objects in the observational training set distribution, and additionally permits parameter inference outside of the trained noise and data at ∼1 minute per object. This expanded regime has broad implications for future applications to astronomical surveys. (Code and a Jupyter tutorial are made publicly available at https://github.com/wangbingjie/sbi_pp.)
Spectroscopic Follow-up of Two Star-forming Objects in the M101 Field*
Authors: Garner Ray , Janowiecki Steven , Mihos J. Christopher
Published: July 2023

We present the spectra of two faint star-forming objects originally identified in our deep narrowband survey of the M101 Group. One is an isolated H ii region near the M101 Group galaxy NGC 5474, and the other is projected close to the background galaxy NGC 5486. Both are spectroscopically confirmed to be physically associated with their nearby host. We estimate the oxygen abundances for each system using strong-line methods. For the source near NGC 5474, we use GALEX UV photometry to estimate an age of ∼200 Myr and suggest a connection to the M101-NGC 5474 interaction.
Modelling the influence of social learning on responsible consumption through directed graphs
Authors: Sibghatullah Shah Syed , Serna Robinson-Julian , Sepúlveda Delgado Omaida
Published: July 2023

This study examines the impact of social learning on consumption and production decisions in a societal context. Individuals learn the actual value of nature through information and subsequent network communication, which is illustrated using the Directed Graph theory and DeGroot social learning process. In this context, individuals with greater access to private information are called "neighbours." Results suggest that in a perfectly rational scenario, individuals have high confidence in their abilities and base their decisions on a combination of personal experience, perception, and intellect; thus, society is expected to converge towards making responsible consumption choices $ {\mathrm{R}}_{\mathrm{c}}^{\mathrm{*}} $. However, when individuals are bounded or irrational, they exhibit persuasion bias or stubbornness, and diversity, independence, and decentralization are lacking. It leads to a situation where the consumption network lacks wisdom and may never result in responsible consumption choices. Thus finite, uniformly conspicuous neighbours will swiftly converge towards the opinion of the group. When a large proportion of individuals consume excessively (extravagance) or below the optimal level (misery), the consumption network is dominated by unwise decision-makers, leading to a society that prevents promoting sustainability. In conclusion, this study emphasizes the need for a more rational and informed decision-making process in promoting a sustainable future.
Estimation for inverse Weibull distribution under progressive type-Ⅱ censoring scheme
Authors: Ren Haiping , Hu Xue
Published: July 2023

This paper considers the statistical inferences of inverse Weibull distribution under progressive type-Ⅱ censored sample, which is a common distribution in reliability analysis. Two commonly used parameter estimation methods, maximum likelihood estimation and Bayesian estimation, are used in this paper, along with the inverse moment estimation. First, we derive the maximum likelihood estimators of parameters and propose Newtown-Raphson iteration method to solve these estimators. Assuming that shape and rate parameters are independent and follow gamma priors, we further obtain the Bayesian estimators by Lindley approximation. We also derive the inverse moment estimators and construct the generalized confidence intervals using the generalized pivotal quantity. To compare the estimation effects of these methods, we implement Monte Carlo simulation with the help of MATLAB. The simulation results show that the Bayesian estimation method outperforms the other two methods in terms of mean squared error. Finally, we verify the feasibility of these methods by analyzing a set of real data. The results indicate that the Bayesian estimation method provides more accurate estimates than the other two methods.

Published: July 2023

More than just a mere revision, digital culture requires a shift in the paradigm of pedagogical materials/resources design. This chapter highlights not just the need to educate for digital culture but also the importance of proposing a teaching-learning virtual learning environment grounded in and from new-multi literacies. Moreover, it aims to discuss (through flexible, open, and interactive teaching-learning materials/resources) the need to materialize critical literacy practices in democratic socio-political crises Brazil faces under Bolsonaro's regime. So, seeking to establish creative and productive dialogues between the Bakhtinian concept of architectonics and new-multiliteracies, this chapter articulates CGScholar innovative social-network-like learning environment features with the concept of “digital learning prototype,” proposed by Roxane Rojo.
