Published: November 2024

In the data-driven era, graph data is widely distributed in multiple
fields, and its complex network relationships pose higher challenges to
data analysis models. Although graph neural networks (GNNs) perform well
in processing non-Euclidean spatial data, traditional methods are
usually limited to capturing local information through message passing
or relying on graph diffusion to obtain global information. This single
perspective makes it difficult to achieve a balance between global and
local information, especially in heterogeneous graphs, which can easily
lead to information loss or over-smoothing. To this end, we propose
Constrained Diffusion Graph Neural Networks (CDnet), which optimizes the
graph diffusion range by adding dual constraints: Constrained Diffusion
(CD) and Feature Information Flow Routing (FIFR). The CD module reduces
the diffusion depth by adaptively reducing the number of diffusion
steps, efficiently captures global information and reduces invalid
propagation. The FIFR mechanism dynamically regulates the direction and
strength of information flow between nodes to ensure precise control of
information transmission and retention of local features. Extensive
experimental results on public homogeneous and heterogeneous datasets
show that CDnet outperforms state-of-the-art methods, demonstrating its
excellent generalization and robustness in complex graph analysis. Code

AdenoCure 3X: Establishing a Sensitized Cancer Cell Model to Accelerate Novel Drug Discovery
Authors: Tan Ee Wern , Tan Kuan Onn , Goh Bey Hing 
Published: November 2024

Cancer is a major cause mortality globally, and chemotherapy is frequently employed as a treatment for cancer. Regrettably, cancers possess the ability for developing resistance to conventional treatments, and the rising recurrence of these drug-resistant cancers requires further research and the advancement of treatment approaches. To address the growing challenge of chemoresistance, this study presents a novel approach for developing a sensitized cancer cell model using AdenoCure 3X to accelerate the discovery of novel drugs. We constructed a tetracistronic adenoviral vector, Ad-MBRG for targeted delivery of tumour suppressor genes MOAP-1, Bax, and RASSF1A, known to be epigenetically silenced in many cancers and contribute to apoptotic pathway dysfunction. This approach aims to restore apoptotic signaling and enhance cancer cell sensitivity to treatment. The study outlines a multi-step methodology for establishing the Ad-MBRG-mediated sensitized cell model, including amplification and quantification of Ad-MBRG particles, optimization of infection efficiency in the MCF7-CR cancer cell line, and evaluation of their sensitivity compared to non-infected controls. Furthermore, we explored the potential synergistic effects between Ad-MBRG infection and anti-cancer compounds derived from natural products. This model holds promise for screening anti-cancer compounds, particularly those from natural sources, and evaluating their potential to overcome chemoresistance. This paves the way for further exploration of adenovirus-mediated gene therapy as a platform for novel drug discovery and improved cancer treatment strategies.

Authors: Ibrahim Shogar  
Published: November 2024

Regardless of the negative picture casted by the hostile media about Islam, the global community is increasingly showing interest in understanding the Islamic thought and culture for various purposes, including political and economic influence. Thus, Muslim intellectuals need to be aware of this fact and get ready for its implications at both local and global levels. Study of other cultures, i.e., religions, languages and lifestyles of other nations, in the globalizing world, which characterized by free movement of ideas and artificial intelligence (AI) technologies, is important as a basic means for effective communication, mutual understanding and cooperation between nations. The Holy Qur`an shifts attention of the global community to the importance of mutual understanding between nations, saying: “O people! We have created you all out of a male and a female, and have made you into nations and tribes so that you might come to know each another’’ (49:13)[1]. The progress in new technologies, especially in (AI) technology, have significantly influenced the Islamic culture over the last few decades. This paper aims to investigate role and the future directions of Islamic thought and culture, as impacted by the new technologies, especially in its methods of teaching and learning. Critical examination is necessary in adopting the new technologies to ensure that scientific advancements are align with the principles and objectives of Islamic thought. The method adopted in this paper is theoretical and analytical in nature. It is expected that the outcomes of the paper will provide clear guidelines for Islamic thought to harness the potential prospects of new technologies and overcome its challenges in Muslim societies.

Published: November 2024

Abstract
Planets and the stars they orbit are born from the same cloud of gas and dust, and the primordial compositions of rocky exoplanets have been assumed to have iron and refractory abundance ratios consistent with their host star. To test this assumption, we modeled the interior iron-to-rock ratio of 20 super-Earth-sized (1–1.8 R
⊕) exoplanets around stars with homogeneously measured stellar parameters. We computed the core mass fraction (CMF) for each planet and an equivalent “core mass fraction” for each host star based on its Fe and Mg abundances. We then fit a linear correlation using two methods (ordinary least squares and orthogonal distance regression) between planetary and stellar CMF, obtaining substantially different slopes between these two methods (m = 1.3 ± 1.0 and m = 5.6 ± 1.6, respectively). Additionally, we find that 75% of planets have a CMF consistent with their host star to within 1σ, and do not identify a distinct population of high-density super-Mercuries. Overall, we conclude that current uncertainties in observational data and differences in modeling methods prevent definitive conclusions about the relationship between planet and host-star chemical compositions.

Abstract
KIC 6362386 is an eclipsing binary system that exhibits both γ Doradus (γ Dor)–type pulsations and starspots. In this study, we investigated this binary system using the Kepler photometry and the spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope. After employing the PHOEBE program for light-curve and radial-velocity-curve synthesis, analyses reveal that the binary is a circle (e ∼ 0.0006), has a small mass ratio (q ∼ 0.311), and is a detached system consisting of an F-type primary star and an M-type secondary star with masses and radii of M

Gyr. By analyzing the out-of-eclipse residuals, we identify variations in the residuals attributed to both starspots and stellar pulsations. The autocorrelation function analysis indicates the decay time of starspots is approximately 37 days with the rotation period aligning with the orbital period. Considering the masses, radii, and positions of the two components on the Hertzsprung–Russell diagram, we deduce that the γ Dor–type g-mode pulsations came from the primary star where the main frequency is 0.1642c/d. Consequently, KIC 6362386 becomes a valuable target for the investigation of γ Dor–type pulsations and asteroseismology in a binary system.

Published: November 2024

Abstract
Examining reflected light from exoplanets aids in our understanding of the scattering properties of their atmospheres and will be a primary task of future flagship space- and ground-based telescopes. We introduce an enhanced capability of Planetary Intensity Code for Atmospheric Scattering Observations (PICASO), an open-source radiative transfer model used for exoplanet and brown dwarf atmospheres, to produce reflected light phase curves from three-dimensional atmospheric models. Since PICASO is coupled to the cloud code Virga, we produce phase curves for different cloud condensate species and varying sedimentation efficiencies (f
sed) and apply this new functionality to Kepler-7b, a hot Jupiter with phase curve measurements dominated by reflected starlight. We model three different cloud scenarios for Kepler-7b: MgSiO3 clouds only, Mg2SiO4 clouds only, and Mg2SiO4, Al2O3, and TiO2 clouds. All our Virga models reproduce the cloudy region west of the substellar point expected from previous studies, as well as clouds at high latitudes and near the eastern limb, which are primarily composed of magnesium silicates. Al2O3 and TiO2 clouds dominate near the substellar point. We then compare our modeled reflected light phase curves to Kepler observations and find that models with all three cloud condensate species and low sedimentation efficiencies (0.03–0.1) match best, though our reflected light phase curves show intensities approximately one-third of those observed by Kepler. We conclude that a better understanding of zonal transport, cloud radiative feedback, and particle scattering properties is needed to further explain the differences between the modeled and observed reflected light fluxes.
A Self-consistent Model of Shock-heated Plasma in Nonequilibrium States for Direct Parameter Constraints from X-Ray Observations

Published: November 2024

Abstract
X-ray observations of shock-heated plasmas, such as those found in supernova remnants (SNRs), often exhibit features of temperature and ionization nonequilibrium. For accurate interpretation of these observations, proper calculations of the equilibration processes are essential. Here, we present a self-consistent model of thermal X-ray emission from shock-heated plasmas that accounts for both temperature and ionization nonequilibrium conditions. For a given pair of shock velocity and initial electron-to-ion temperature ratio, the temporal evolution of the temperature and ionization state of each element was calculated by simultaneously solving the relaxation processes of temperature and ionization. The resulting thermal X-ray spectrum was synthesized by combining our model with the AtomDB spectral code. Comparison between our model and the nei model, a constant-temperature nonequilibrium ionization model available in the XSPEC software package, reveals a 30% underestimation of the ionization timescale in the nei model. We implemented our model in XSPEC to directly constrain the shock wave’s properties, such as the shock velocity and collisionless electron heating efficiency, from the thermal X-ray emission from postshock plasmas. We applied this model to archival Chandra data of the SNR N132D, providing a constraint on the shock velocity of ∼800 km s−1, in agreement with previous optical studies.

Published: November 2024

Abstract
We present the results of a four-year velocity-resolved reverberation mapping (RM) campaign of the changing-look active galactic nucleus (CL-AGN) NGC 4151 during its outburst phase. By measuring the time lags of the Hα, Hβ, Hγ, He i, and He ii emission lines, we confirm a stratified broad-line region (BLR) structure that aligns with predictions from photoionization models. Intriguingly, we observed an “anti-breathing” phenomenon, where the lags of broad emission lines decreased with increasing luminosity, contrary to the typical expectation. This anomaly may be attributed to the influence of the ultraviolet-optical lag or nonvirialized motions in the BLR gas. Velocity-resolved RM and ionization mapping analyses revealed rapid and significant changes in the BLR geometry and kinematics on timescales of less than a year, which cannot be interpreted by any single mechanism, such as an inhomogeneous BLR, variations in radiation pressure, or changes in the illuminated ionizing field. Additionally, the Hβ lags of NGC 4151 and other CL-AGNs agree with the radius–luminosity relationship established for AGNs with low accretion rates, implying that the CL phenomenon is more likely driven by intrinsic changes in the accretion rate rather than obscuration. These findings provide new insights into the complex internal processes of CL-AGNs and highlight the importance of long-term, multiline RM for understanding BLR structures, geometry, and kinematics.
