Abstract
We present very early photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2023bee, starting about 8 hr after the explosion, which reveal a strong excess in the optical and nearest UV (U and UVW1) bands during the first several days of explosion. This data set allows us to probe the nature of the binary companion of the exploding white dwarf and the conditions leading to its ignition. We find a good match to the Kasen model in which a main-sequence companion star stings the ejecta with a shock as they buzz past. Models of double detonations, shells of radioactive nickel near the surface, interaction with circumstellar material, and pulsational delayed detonations do not provide good matches to our light curves. We also observe signatures of unburned material, in the form of carbon absorption, in our earliest spectra. Our radio nondetections place a limit on the mass-loss rate from the putative companion that rules out a red giant but allows a main-sequence star. We discuss our results in the context of other similar SNe Ia in the literature.
A Broken “α–intensity” Relation Caused by the Evolving Photosphere Emission and the Nature of the Extraordinarily Bright GRB 230307A

Abstract
GRB 230307A is one of the brightest gamma-ray bursts detected so far. With the excellent observation of GRB 230307A by the Fermi Gamma-ray Burst Monitor, we can reveal the details of prompt emission evolution. As found in high time-resolution spectral analysis, the early low-energy spectral indices (α) of this burst exceed the limit of synchrotron radiation (α = −2/3) and gradually decreases with the energy flux (F). A tight E
p ∝ F
0.54 correlation holds within the whole duration of the burst, where E
p is the spectral peak energy. Such an evolution pattern of α and E
p with intensity is called “double tracking.” For the α–F relation, we find a log Bayes factor ∼210 in favor of a smoothly broken power-law function over a linear function in log-linear space. We call this particular α–F relation a broken “α–intensity” and interpret it as the evolution of the ratio of thermal and nonthermal components, which is also the evolution of the photosphere. GRB 230307A with a duration of ∼35 s, if indeed at a redshift of z = 0.065, is likely a neutron star merger event (i.e., it is intrinsically “short”). Intriguingly, different from GRB 060614 and GRB 211211A, this long event is not composed of a hard spike followed by a soft tail, suggesting that the properties of the prompt emission light curves are not a good tracer of the astrophysical origins of the bursts. The other possibility of z = 3.87 would point toward a very peculiar nature of both GRB 230307A and its late-time thermal-like emission.
The Interaction between AGN and Starburst Activity in the Circumnuclear Region of NGC 7469 as Viewed with JWST
Authors: Zhang Lulu , Ho Luis C. 
Published: August 2023

Abstract
We combine mid-infrared diagnostics obtained from integral-field-unit observations taken with Mid-Infrared Instrument/Medium Resolution Spectrograph on the James Webb Space Telescope with cold molecular gas information derived from Atacama Large Millimeter/submillimeter Array observations of CO(1–0) emission to investigate the star formation rate and efficiency within the central ∼1.5 kpc × 1.3 kpc region of the Seyfert 1 galaxy NGC 7469 on ∼100 pc scales. The active nucleus leaves a notable imprint on its immediate surroundings by elevating the temperature of the warm molecular gas, driving an ionized gas outflow on subkiloparsec scales, and selectively destroying small dust grains. These effects, nevertheless, have relatively little impact on the cold circumnuclear medium or its ability to form stars. Most of the star formation in NGC 7469 is confined to a clumpy starburst ring, but the star formation efficiency remains quite elevated even for the nuclear region that is most affected by the active nucleus.
Rotational Flows in Solar Coronal Flux Rope Cavities
Authors: Liakh Valeriia , Keppens Rony 
Published: August 2023

Abstract
We present a 2.5D magnetohydrodynamic simulation of a systematically rotating prominence inside its coronal cavity using the open-source MPI-AMRVAC code. Our simulation starts from a nonadiabatic, gravitationally stratified corona, permeated with a sheared arcade magnetic structure. The flux rope (FR) is formed through converging and shearing footpoints driving, simultaneously applying randomized heating at the bottom. The latter induces a left–right asymmetry of temperature and density distributions with respect to the polarity inversion line. This asymmetry drives flows along the loops before the FR formation, which gets converted to net rotational motions upon reconnection of the field lines. As the thermal instability within the FR develops, angular momentum conservation about its axis leads to a systematic rotation of both hot coronal and cold condensed plasma. The initial rotational velocity exceeds 60 km s−1. The synthesized images confirm the simultaneous rotations of the coronal plasma seen in 211 and 193 Å and condensations seen in 304 Å. Furthermore, the formation of the dark cavity is evident in 211 and 193 Å images. Our numerical experiment is inspired by observations of so-called giant solar prominence tornadoes and reveals that asymmetric FR formation can be crucial in triggering rotational motions. We reproduce observed spinning motions inside the coronal cavity, augmenting our understanding of the complex dynamics of rotating prominences.
Efficacy Comparison Between Toric Posterior Chamber Phakic IOL and Posterior Chamber Phakic IOL Plus Modified Steep Meridian Corneal Relaxing Incision for Moderate to High Astigmatism Corrections
Authors: Liu Shengtao , Wang Xuejun , Chen Xun , Wang Xiaoying , Zhao Jing , Zhou Xingtao 
Published: August 2023

Purpose:
To compare posterior chamber phakic intraocular lens (Implantable Collamer Lens [STAAR Surgical]) (ICL) plus modified steep meridian corneal relaxing incision (MS-CRI) to toric posterior chamber phakic intraocular lens (Toric Implantable Collamer Lens [STAAR Surgical]) (TICL) implantation for the correction of moderate to high astigmatism.

Methods:
In this prospective, randomized clinical trial, patients with myopia who had moderate to high astigmatism (200 eyes) were enrolled and divided into TICL (n = 100) and MSCRI (n = 100) groups. All patients underwent examinations for uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and subjective refraction before surgery and at the 1- and 6-month follow-up visits. Vector astigmatism analysis was evaluated using the Alpins method.

Results:

The mean UDVA and CDVA demonstrated significant improvement after surgery in both groups. During the 6-month follow-up, the MS-CRI group showed a slight regression tendency (
P
< .001) and the TICL group was stable for the astigmatism correction (
P
= .510). At 6 months postoperatively, the mean magnitudes of the surgically induced astigmatism were 1.46 ± 0.53 and 1.10 ± 0.48 diopters (
P
< .001). The correction index of the TICL group was closer to 1 compared to that of the MS-CRI group (0.95 vs 0.76). Approximately 99% of eyes in the TICL group had angle of error within ±15°, whereas 89% eyes in the MS-CRI group were within that range. A significant relationship between the magnitudes of target induced astigmatism and correction index was noted in the MS-CRI group (
P
< .001), but not in the TICL group (
P
= .592).

Conclusions:
TICL implantation could achieve better visual outcomes for correcting moderate to high astigmatism compared to ICL implantation plus MS-CRI.

The Impact of Covid-19 on Academic Practice: A Dilemma-Driven Self-Study Inquiry at an Institution of Higher Learning
Authors: Tshuma Tholani 
Published: August 2023

This inquiry was a dilemma-driven, object-inquiry self-study. The study followed visual methodologies in unpacking the impact of Covid-19 on the practices of a practitioner at a rural university. During the Covid-19 pandemic, I was becoming increasingly dissatisfied with my daily practice as an academic because I struggled to locate my footing in what has been dubbed the ‘new normal’ about online student teaching and assessment. In my bid to investigate the dissatisfactions I faced due to Covid-19, I followed the self-study methodology, which entailed my engagement in reflexivity cycles, and feedback from critical friends. My critical friends played a crucial validation role during my data collection, analysis, and drawing of conclusions from multiple data forms that included journal entries and discussions with others. The collected data was thematically and analyzed from deductive to inductive perspective through the process of coding. This inquiry established that the outbreak of Covid-19 led to dilemmas of practice that stemmed from my being deskilled, techno and Covid-phobic; poor individual adaptability; inadequate TPKC; and the shortcomings of working as an isolated silo. It emerged that these dilemmas of practice escalated into professional traumas through working in isolated silos in virtual platforms. Thus, through making our challenges of practice public, we tend to benefit from the pool of probing expertise of others. Whilst the advent of Covid-19 posed unwelcome professional traumas, it was through the probing power of ‘the second voice’ that the over-shadowed professional growth opportunities in this pandemic induced ‘new normal’ was unveiled.

Published: August 2023

In colorectal cancer (CRC) in addition to the most common mutations in the second exon of KRAS, there are rarer mutations that are not well understood as prognostic markers.Description of cases. We describe two clinical cases of moderately differentiated adenocarcinoma (low-grade, G2), which manifested a complicated course in a 67-year-old woman – intestinal obstruction (case 1) and in a 62-year-old man – paratumorous abscess (case 2). Both cases were characterized by the development of regional and distant metastases (liver, brain) and a short relapse-free period. We found rare sporadic mutations of KRAS A146V and A59G with microsatellite stability and no mutation in the V600 BRAF site.Discussion. In the presented case 1, the KRAS A146V mutation was detected, the frequency of its detection in our practice of testing 2103 cases of CRC was 0.48%. Case 2 shows the extremely rare A59G mutation. Among the patients with CRC we studied, we found mutations in codon 59 in only two, which amounted to 0.095%. Both rare mutations represent separate molecular subgroups of CRC, characterized by an unfavorable clinical outcome and requiring the development of special treatment regimens.

Pounded yam is a staple food consumed in Makurdi, Benue State. The food is sold along major streets and roads in the town, as such; it is prone to bacterial contamination from different sources. The study was aimed at assessing the contamination and susceptibility pattern of bacteria isolated from pounded yam sold along major roads in Makurdi metropolis. One hundred and forty (140) samples of pounded yam were aseptically collected from seven food vending sites (Wurukum, Wadata, High level, Naka road, Otukpo road, Gboko road and North bank) and analyzed for bacterial contamination using standard microbiological procedures. The Kirby-Bauer disk diffusion method was used for the antibacterial susceptibility testing. The antibiotics tested were Septrin, Chloramphenicol, Sparfloxacin, Ciprofloxacin, Amoxicillin, Augmentin, Gentamycin, Pefloxacin, Tarivid and Streptomycin. If a bacterial isolate proved resistant to at least three of the tested antibiotics, it was deemed to be multi-drug resistant (MDR). A total of four species of bacteria which included Staphylococcus aureus (35.66%), Escherichia coli (18.18%), Klebsiella spp (11.20%) and Proteus spp (34.97%), were isolated from the pounded yam samples. The mean total viable count of all the samples; which ranges from 2.61x105cfu/g (Wadata) to 3.25x105cfu/g (Otukpo road) are within the acceptable limits for food. Staphylococcus spp, Escherichia coli and Proteus spp were multidrug resistant to four, six and three antibiotics respectively, according to the antibacterial susceptibility test. Staphylococcus spp showed 31.37% susceptibility to Septrin, 37.25% to Streptomycin and 33.33% of the Staphylococcus isolates were sensitive to Sparfloxacin and Amoxycillin. For Escherichia coli, more than 50% of the 26 Escherichia coli isolates showed resistance to Septrin (46.16%), Sparfloxacin (42.31%), Amoxicillin (42.31%), Gentamycin (38.46%), Perfloxacin ((46.15%) and Streptomycin (23.08%). Proteus spp showed 44.00% susceptibility to Chloramphenicol, 30.00% to Sparfloxacin and 40.00% to amoxicillin. Klebsiella spp showed 25.00% susceptibility to Amoxicillin only. The study identified that pounded yam sold along major roads in Makurdi metropolis are contaminated with bacteria of public health importance. Therefore hygienic way of food preparation is of utmost importance to prevent contamination of food with these organisms resulting to food borne diseases.

Dermatophytes are one of the major aetiologic agents of cutaneous mycoses Senna occidentalis is among the plants used in traditional herbal medicine in treating fungal skin infections and it is shown from literature to contain phytochemicals which are attributed to its antidermatophytic activity. This work is aimed at determining the Phytoconstituents and antidermatophytic activity of leaves and seeds crude extracts of the Senna occidentalis plant . The study is a qualitative study that determines the phytoconstituents and antidermatophytic activity of the plant extracts on some clinical dermatophyte isolates. The plant parts were sampled and were used to obtain aqueous and n-hexane extracts using distilled water and n-hexane as extracting solvents respectively. Phytochemical analysis was done on the extracts to determine the presence of secondary metabolites. The antidermatophytic activity of the extracts on clinical dermatophytes isolates was determined using poisoned food technique. Aqueous extraction gave higher percentage extraction yield than n-hexane extract . All extracts contain secondary metabolites and the extracts showed varying degree of percentage growth inhibition on the isolates. Phytochemical screening of the leaves and seeds extracts of Senna occidentalis revealed the presence of alkaloids, saponins, tannins and other phytoconstituents. The Senna occidentalis leaves and seeds extracts showed growth inhibition percentage (I) ranging between 9% to 39.8% for n-hexane leaf extract,1.3% to 52.6% for aqueous leaf extract,2.6% to 57.2% for n-hexane seed extract and 12.8% to 61.1% for aqueous seed extract. Senna occidentalis leaves and seeds extract have shown varying potential in inhibiting dermatophyte growth with no extract having 100% inhibition percentage on all the tested dermatophytes.

Framework is a group of parts or components that collaborate with each other to achieve a goal. In planning the educational and learning framework and the instructive and preparatory strategies made in the modern and military fields. The idea is reason to recognize the target of the framework. The reason is that frameworks can be regular and human. Training is more centered around character styling and improvement. While preparing emphasizes the development of training abilities carried out in a school climate, while the use of preparation is largely based on a modern climate. In this way, the standards of learning are guidelines for educators in implementing successful learning conditions. There are two attributes of the show framework approach, in particular the teaching and developing framework and experience approach to make it simple for students to learn.

Self-confidence is a very important aspect, especially in the student learning process, with confidence there will be a process of change in students not only in learning outcomes but also in student behavior and attitudes, namely courage, activeness, and student self-actualization during the teaching and learning process. Building a confident attitude needs to be supported by several things, especially the family environment (parents). This study describes how the role of parents in giving appreciation to foster self-confidence in children in home education. This study aims to determine how the role of parental appreciation in building children's self-confidence and what factors hinder and support efforts to build children's self-confidence. This research uses descriptive qualitative methods. The data was validated using the data source triangulation technique (combined observation, interview, and documentation). The sources and informants in this study are teachers, students, and parents of students. The results stated that parental appreciation acts as a motivation for children to be enthusiastic about learning, as an increase in children's creativity, and as an increase in children's independence. Factors that act as supporters and inhibitors are, cooperation between parents and children, mutual openness and understanding between parents and children, parents’ educational background, economic background, environment, free time that parents provide, parents' busyness, and fulfillment of children's needs by parents.
