Abstract
We present a new high-precision, JWST-based, strong-lensing model for the galaxy cluster Abell 2744 at z = 0.3072. By combining the deep, high-resolution JWST imaging from the Grism Lens Amplified Survey from Space–JWST and Ultradeep NIRSpec and NIRCam Observations before the Epoch of Reionization programs and a Director’s Discretionary Time program, with newly obtained Very Large Telescope/Multi Unit Spectroscopic Explorer (MUSE) data, we identify 32 multiple images from 11 background sources lensed by two external subclusters at distances of ∼160″ from the main cluster. The new MUSE observations enable the first spectroscopic confirmation of a multiple-image system in the external clumps. Moreover, the reanalysis of the spectrophotometric archival and JWST data yields 27 additional multiple images in the main cluster. The new lens model is constrained by 149 multiple images (∼66% more than in our previous model) covering an extended redshift range between 1.03 and 9.76. The subhalo mass component of the cluster includes 177 member galaxies down to m
F160W = 21, of which 163 are spectroscopically confirmed. Internal velocity dispersions are measured for 85 members. The new lens model is characterized by a remarkably low scatter between the predicted and observed positions of the multiple images (0.″43). This precision is unprecedented given the large multiple-image sample, the complexity of the cluster mass distribution, and the large modeled area. The improved precision and resolution of the cluster total mass distribution provides a robust magnification map over a ∼30 arcmin2 area, which is critical for inferring the intrinsic physical properties of the highly magnified, high-z sources. The lens model and the new MUSE redshift catalog are released with this publication.

Abstract
The UltraViolet imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) program provides Hubble Space Telescope (HST)/UVIS F275W imaging for four CANDELS fields. We combine this UV imaging with existing HST/near-IR grism spectroscopy from 3D-HST+AGHAST to directly compare the resolved rest-frame UV and Hα emission for a sample of 979 galaxies at 0.7 < z < 1.5, spanning a range in stellar mass of 108−11.5
M
⊙. Using a stacking analysis, we perform a resolved comparison between homogenized maps of rest-UV and Hα to compute the average UV-to-Hα luminosity ratio (an indicator of burstiness in star formation) as a function of galactocentric radius. We find that galaxies below stellar mass of ∼109.5
M
⊙, at all radii, have a UV-to-Hα ratio higher than the equilibrium value expected from constant star formation, indicating a significant contribution from bursty star formation. Even for galaxies with stellar mass ≳109.5
M
⊙, the UV-to-Hα ratio is elevated toward their outskirts (R/R
eff > 1.5), suggesting that bursty star formation is likely prevalent in the outskirts of even the most massive galaxies, but is likely overshadowed by their brighter cores. Furthermore, we present the UV-to-Hα ratio as a function of galaxy surface brightness, a proxy for stellar mass surface density, and find that regions below ∼107.5
M
⊙ kpc−2 are consistent with bursty star formation, regardless of their galaxy stellar mass, potentially suggesting that local star formation is independent of global galaxy properties at the smallest scales. Last, we find galaxies at z > 1.1 to have bursty star formation, regardless of radius or surface brightness.
Isotopic Enrichment of Planetary Systems from Asymptotic Giant Branch Stars
Authors: Parker Richard J. , Schoettler Christina 
Published: July 2023

Abstract
Short-lived radioisotopes, in particular 26Al and 60Fe, are thought to contribute to the internal heating of the Earth, but are significantly more abundant in the solar system compared to the interstellar medium. The presence of their decay products in the oldest solar system objects argues for their inclusion in the Sun’s protoplanetary disk almost immediately after the star formation event that formed the Sun. Various scenarios have been proposed for their delivery to the solar system, usually involving one or more core-collapse supernovae of massive stars. An alternative scenario involves the young Sun encountering an evolved asymptotic giant branch (AGB) star. AGBs were previously discounted as a viable enrichment scenario for the solar system due to the presumed low probability of an encounter between an old, evolved star and a young pre-main-sequence star. We report the discovery in Gaia data of an interloping AGB star in the star-forming region NGC2264, demonstrating that old, evolved stars can encounter young forming planetary systems. We use simulations to calculate the yields of 26Al and 60Fe from AGBs and their contribution to the long-term geophysical heating of a planet, and find that these are comfortably within the range previously calculated for the solar system.

Abstract
Transverse oscillations that do not show significant damping in solar coronal loops are found to be ubiquitous. Recently, the discovery of high-frequency transverse oscillations in small-scale loops has been accelerated by the Extreme Ultraviolet Imager on board Solar Orbiter. We perform a meta-analysis by considering the oscillation parameters reported in the literature. Motivated by the power law of the velocity power spectrum of propagating transverse waves detected with CoMP, we consider the distribution of energy fluxes as a function of oscillation frequencies and the distribution of the number of oscillations as a function of energy fluxes and energies. These distributions are described as a power law. We propose that the power-law slope (δ = −1.40) of energy fluxes depending on frequencies could be used for determining whether high-frequency oscillations dominate the total heating (δ < 1) or not (δ > 1). In addition, we found that the oscillation number distribution depending on energy fluxes has a power-law slope of α = 1.00, being less than 2, which means that oscillations with high energy fluxes provide the dominant contribution to the total heating. It is shown that, on average, higher energy fluxes are generated from higher-frequency oscillations. The total energy generated by transverse oscillations ranges from about 1020 to 1025 erg, corresponding to the energies for nanoflare (1024–1027 erg), picoflare (1021–1024 erg), and femtoflare (1018–1021 erg). The respective slope results imply that high-frequency oscillations could provide the dominant contribution to total coronal heating generated by decayless transverse oscillations.

Aims: We address the following questions: 1) Which are the main vegetation types that currently occur in the Arid Chaco? 2) Do those vegetation types differ in terms of floristic composition, endemism, chorotypes and life forms? and 3) Is there any spatial association between the vegetation types and the environmental heterogeneity of the Arid Chaco?Study area: The southwestern extreme of the Gran Chaco, in Central-Western Argentina.Methods: The survey was based on a dataset comprising 654 relevés collected according to the Braun-Blanquet method. Data were classified by the hierarchical ISOmetric feature mapping and Partition Around Medoids (ISOPAM), and ordinated through isometric feature mapping (ISOMAP). Bioclimatic and edaphic variables were related to the ISOMAP ordination.Results: We recorded 439 vascular plant species, 62 endemic at the national level and 22 endemic species restricted to the study and surrounding environments in Central-Western Argentina. A total of nine vegetation types, belonging to four major clusters, were identified. The most prominent chorotypes included species distributed in the Chaco region and in the Arid Chaco/Monte phytogeographic units. The predominant life forms were micro- and nano-phanerophytes, followed by hemicryptophytes, chamaephytes and mesophanerophytes.Conclusions: Major results highlighted that xerophytic shrublands are the most common vegetation types in this area as a result of the historical and present use, while old growth forests were constrained to areas with low anthropogenic disturbance in the last decades or to protected areas. Most vegetation types (with the exception of halophytic environments) are poorly differentiated from a floristic point of view; however, they clearly differ in physiognomy. The floristic composition of the vegetation types described revealed numerous species in common with other sectors of the Chaco of northern Argentina, Bolivia and Paraguay. Although the number of species restricted to the Arid Chaco was quite low, the most relevant chorotype included species with Western and Eastern Chaco distribution, conferring a clear Chaquenian identity to this area and discriminating it from other phytogeographic units.Taxonomic reference: Catálogo de las Plantas Vasculares del Cono Sur (Zuloaga et al. 2008) and its online update (http://www.darwin.edu.ar).Abbreviations: ISOMAP = isometric feature mapping; ISOPAM = isometric partitioning around medoids.

Abstract
CTL differentiation is controlled by the crosstalk of various transcription factors and epigenetic modulators. Uncovering this process is fundamental to improving immunotherapy and designing novel therapeutic approaches. In this study, we show that polycomb repressive complex 1 subunit chromobox (Cbx)4 favors effector CTL differentiation in a murine model. Cbx4 deficiency in CTLs induced a transcriptional signature of memory cells and increased the memory CTL population during acute viral infection. It has previously been shown that besides binding to H3K27me3 through its chromodomain, Cbx4 functions as a small ubiquitin-like modifier (SUMO) E3 ligase in a SUMO-interacting motifs (SIM)-dependent way. Overexpression of Cbx4 mutants in distinct domains showed that this protein regulates CTL differentiation primarily in an SIM-dependent way and partially through its chromodomain. Our data suggest a novel role of a polycomb group protein Cbx4 controlling CTL differentiation and indicated SUMOylation as a key molecular mechanism connected to chromatin modification in this process.

Published: July 2023

Background:
Recently, the role of biochemical factors in the etiology of oral squamous cell carcinoma (OSCC) has attracted some attention. Serum levels of biochemical factors may change in cancer patients. This study aimed to assess the serum level of folate, Vitamin B12, homocysteine, iron, copper, and selenium in patients with OSCC.

Materials and Methods:
This descriptive analytical study was conducted on 30 primary OSCC patients (15 males and 15 females) presenting to Imam Khomeini Cancer Institute, who had not yet undergone treatment. Blood samples were taken and serum levels of folate, Vitamin B12, homocysteine, iron, copper, and selenium were measured. Serum levels of micronutrients in patients with different tumor sizes were analyzed by one-way ANOVA. Serum levels of micronutrients were compared among groups with and without metastasis and lymph node involvement using Student's t-test (P < 0.05).

Results:
Serum levels of B12, folic acid, homocysteine, copper, iron, and selenium were 232.5 ± 102.68, 8.66 ± 4.06, 18.87 ± 8.81, 96.0 ± 22.64, 55.27 ± 40.58, and 92.47 ± 18.83 ng/mL, respectively. Relatively similar values were measured in patients with different tumor sizes with and without lymph node involvement and presence or absence distant metastasis. However, the serum level of folic acid in OSCC patients without lymph node involvement was significantly higher than that in OSCC patients with lymph node involvement (P < 0.05).

Conclusion:
Despite some variations, serum levels of micronutrients in OSCC patients were within the normal limits. Considering the variations in serum level of copper in OSCC patients, it may be used as a diagnostic marker. However, further studies are warranted in this respect.

Published: July 2023

Background:
Porcelain fracture or chipping is one of the limitations of all ceramic restorations. This study investigated the shear bond strength (SBS) of composite resins to lithium disilicate ceramics using universal bondings and different methods of surface preparation.

Materials and Methods:
In this experimental study, 72 specimens of e.max computer-aided design and computer-aided manufacturing (CAD/CAM) ceramic blocks were divided into six groups of 12 according to surface treatment: Group I-Hydrofluoric (HF) acid etching + All-Bond Universal bonding (ABU), Group II-Bur roughening (BR) + HF + ABU, Group III-BR + HF + Bis-Silane (Si) + ABU, Group IV-Sandblasting (SB) + ABU, Group V-SB + HF + ABU, Group VI-SB + HF + Si + ABU. After bonding of composite resin to the prepared ceramic surface and storage of samples in distilled water for 24 h, SBS test was done using the universal testing machine at a crosshead speed of 0.5 mm/min. Data were analyzed using the analysis of variance and Tukey's post hoc test (α = 0.05).

Results:
The mean values of SBS in six studied groups were 6.65 ± 2.78 MPa, 8.56 ± 2.69 MPa, 8.49 ± 2.14 MPa, 3.13 ± 1.66 MPa, 7.94 ± 2.4 MPa, and 10.04 ± 2.47 MPa, respectively. The mean values of SBS were significantly different (P < 0.001). The highest value of SBS was observed in Group VI and the lowest in Group IV.

Conclusion:
Ceramic sandblasting followed by HF etching, Bis Si, and ABU resulted in a higher SBS of composite resins to lithium disilicate ceramics.

Published: July 2023

Background:
Sexual desire and sexual activity are natural needs of human beings, which can be problematic and lead to various sexual disorders, if not used in the right way, including hypersexuality. The present study aimed to compare the effect of dialectical behavior therapy (DBT) and aripiprazole drug on marital instability in patients with hypersexuality.

Materials and Methods:
This experimental case--control Pretest--Posttest Control Group Design with follow up was done on 27 male and female patients with hypersexuality having at least a higher education degree selected from four hospitals and psychiatric centers including Khorshid Hospital, Asgariyeh Specialized Hospital, Farhangian Clinic and Imam Reza Medical Center in Isfahan and were randomly assigned to two groups of treatment (nine patients in every group) and one group of control (nine patients) after adjusting the age and gender. Pretest phase was done for both three groups using Marital Instability Index (MII). The first treatment group underwent DBT intervention for eight sessions of 2 hours (once a week), and the second experimental group was prescribed aripiprazole for 2 months. Afterwards, the posttest and follow-up were performed for all the three groups. The data were analyzed using SPSS 24 and multivariate analysis of covariance (MANCOVA).

Results:
The findings showed that DBT and aripiprazole had little effect on the problem of marital instability in patients with hypersexuality (p > 0.05); also, there was no significant difference between the effect of DBT and aripiprazole (p > 0.05).

Conclusion:
DBT and the drug aripiprazole cannot have a significant effect on the marital instability in patients.

An Appraisal of the Implications of Deep Fakes: The Need for Urgent International Legislations
Authors: Nnamdi Nmesoma , Oniyinde O.A. , Abegunde Babalola 
Published: July 2023

Purpose: Artificial intelligence as a subfield of the Fourth Industrial Revolution has been a controversial concept since its inception. The reason for its controversy is that through it, incredible inventions and also inventions detrimental to the society have surfaced. A deep fake is an Artificial Intelligence technology that creates videos and images of persons and events that in fact did not happen. The aim of this paper is to evaluate the concept of deepfake, its positive impacts and threats posed to individuals, corporate institutions and nations. It further assesses the legal implications of and provisions against deep fakes.
Methodology: The research methodology adopted in this study is doctrinal. Just like every Artificial Intelligence technology, it has benefits that cut across the marketing, fashion, and art industry among others. However, the issue for determination remains whether the positive impact of this AI technology supersedes the negative impacts.
Findings: Findings revealed that it has a high tendency to deceive an average person and also create uncertainty about the authenticity of a piece of information. This can lead to the spread of fake news, fraud, blackmail, fabrication of evidence, and even national and global insecurity. Trust in the social media and the internet generally will face a great decline at the spread of deepfakes, this will then be a medium for denial of videos that are in fact true.
Unique Contribution to Theory, Practice and Policy: The world is set to face a new and modified aspect of social engineering that will require an upgrade in cybersecurity techniques and strategies. By virtue of the sensitivity of the negative impacts of deepfake, this study concludes that it is necessary to promulgate legislations both at national and international levels to curb or regulate deepfakes.
Managing the Menace of Cattle Rustling and Banditry in North Rift Kenya: The Role of Pokot Women
Authors: Marigat Saul Kipchirchir , Cheruiyotomo Juddy Chebet 
Published: July 2023

Purpose: The purpose of this article is to create a discourse surrounding women role in combating cattle rustling and banditry in north rift, Kenya. The article underscores that Pokot women play key roles in instigating cattle rustling and banditry in the north rift region. While media generally perceive women as passive bystanders, it projects men as the protagonists and antagonists during conflict. The thinking that women are only victims of conflicts, just because of the biases in reporting by the media, needs to be critically looked into.
Methodology: The study relied on secondary sources where information from books, journals, periodicals and online opens sources was acquired before deep content analysis was carried and presented in prose.
Findings: The study found that although women bear the brunt of conflicts as the post-Cold War examples clearly show, they are not always on the receiving end. Thus, the suffering that women go through because of conflicts has made them become active participants in such fights. While the article conceded that there are several other causal factors accounting for cattle rustling in the north rift, it finds that the role of Pokot women in fuelling livestock theft is a crucial one.
Recommendation: The article recommended to policy makers that, if meaningful and sustainable peace is to be made in the north rift, they should consider engaging Pokot women in the peacemaking processes.
