Authors: De Oliveira Francyellen Beserra , Dos Santos Maria Eloiza Nenen , Torres Maria da Conceição de Menezes
Published: February 2023

As plantas da família Malvaceae fazem parte do elenco de plantas medicinais, utilizadas desde a antiguidade para o tratamento de diversas doenças. Os gêneros Bombax L. e Pseudobombax Dugrand pertencem a família Malvaceae e a subfamília Bombacoideae. As plantas desses gêneros são utilizadas no tratamento de doenças como problemas de pele, gastrite, dores nas costas, infecções e fraqueza. Nesse sentido, a presente pesquisa teve como objetivo realizar uma revisão de literatura sobre os constituintes químicos e atividades biológicas dos gêneros Bombax e Pseudobombax. Foram utilizadas as plataformas Scifinder, Periódicos Capes e Science Direct para pesquisa dos artigos publicados nos últimos dez anos. Com base nos dados obtidos, foi possível observar uma relação entre os metabólitos secundários e atividades biológicas dos dois gêneros. Entre os principais metabólitos secundários do gênero Bombax estão os flavonoides, alcaloides, compostos fenólicos, taninos e saponinas, todos obtidos da espécie Bombax ceiba L. Para essa espécie, foram isolados mais de 40 compostos, entre os principais estão o lupeol, β-amirina e linoleato de β-sistosterol. Para o gênero Pseudobombax, foram encontrados flavonoides, alcaloides, taninos, saponinas, esteroides, xantonas e chalconas, no entanto não foram relatados compostos isolados. Em relação as atividades biológicas, são relatadas na literatura para o gênero Bombax atividades antioxidante, anti-inflamatória e antidiabética, enquanto que as espécies de Pseudobombax, apresentaram em comum as atividades antioxidante e anti-inflamatória, além da atividade antimicrobiana e antinociceptiva, ausentes no gênero Bombax. Apesar do gênero Pseudobombax ser o segundo maior gênero da subfamília Bombacoideae, há poucos estudos na literatura, especialmente, sobre sua composição química, havendo a necessidade de novos estudos. Portanto, estima-se que este estudo possa contribuir para desenvolvimento de pesquisas futuras envolvendo as plantas dos gêneros Bombax e Pseudobombax.

Will ChatGPT get you caught? Rethinking of Plagiarism Detection
Authors: Khalil Mohammad , Er Erkan
Published: February 2023

The rise of Artificial Intelligence (AI) technology and its impact on education has been a topic of growing concern in recent years. The new generation AI systems such as chatbots have become more accessible on the Internet and stronger in terms of capabilities. The use of chatbots, particularly ChatGPT, for generating academic essays at schools and colleges has sparked fears among scholars. This study aims to explore the originality of contents produced by one of the most popular AI chatbots, ChatGPT. To this end, two popular plagiarism detection tools were used to evaluate the originality of 50 essays generated by ChatGPT on various topics. Our results manifest that ChatGPT has a great po-tential to generate sophisticated text outputs without being well caught by the plagiarism check software. In other words, ChatGPT can create content on many topics with high originality as if they were written by someone. These findings align with the recent concerns about students using chatbots for an easy shortcut to success with minimal or no effort. Moreover, ChatGPT was asked to verify if the essays were generated by itself, as an additional measure of plagiarism check, and it showed superior performance compared to the tradi-tional plagiarism-detection tools. The paper discusses the need for institutions to consider appropriate measures to mitigate potential plagiarism issues and advise on the ongoing debate surrounding the impact of AI technology on education. Further implications are discussed in the paper.

High-intensity airborne sound generated by irradiation of nanosecond laser pulse to water-immersed optical absorber
Authors: Miyazaki Kota , Aizawa Koji
Published: February 2023

A high-intensity and small-size laser-induced airborne sound source was developed for application to non-contact and non-destructive testing. A laser target composed of a polycarbonate (PC) plate and a black fluoro-rubber (FKM) film immersed in circulating water was used as the sound source. The maximum sound pressure of about 15.2 kPa was obtained at a distance of about 11 mm from the surface of the laser target when a pulsed laser with its energy of about 110 mJ was irradiated to a 0.1 mm thick FKM film immersed in circulating water. The ratio of maximum pressure to the irradiation energy was stabilized up to 60 shots of pulsed laser irradiation. The maximum sound pressure of about 18 kPa was obtained through the 50 mm length cylindrical PC pipe of 3.2 mm in diameter when a pulsed laser at an energy of 120 mJ was irradiated to a 0.5 mm thick FKM film immersed in circulating water.

Published: February 2023

We deposited an ultrathin CoFeB(1.1 nm) layer, which functions as a storage layer of MgO-based magnetic tunnel junctions for spin-transfer-torque (STT) magnetoresistive random-access memory (MRAM), on ϕ300 mm wafers at 100 K and investigated its effect on the magnetization dynamics of CoFeB. We observed clear reductions in both the inhomogeneous linewidth and total magnetic damping parameter for the CoFeB layer deposited at 100 K compared to those deposited at 300 K through the improvement in the interfacial quality. The results show that deposition at cryogenic temperatures is an effective manufacturing process for high-quality magnetic thin films with low magnetic damping.

Published: February 2023

تهدف هذه الدراسة إلى التحقيق في تأثير السياق على استخدام الأفعال الناقصة الدلالية (deontic modals) في الجزء الأول من سلسلة هاري بوتر للكاتبة ج. ك. رولينغ، أي هاري بوتر وحجر الفيلسوف. تركز الدراسة على أفعال المساعدة الناقصة (Modal Auxiliary Verbs)، نظرًا لدورها المهم في عمليات التفاعل، مثل تحسين العلاقة بين المتحدثين في التواصل اليومي، والتعبير عن مواقفهم واتجاهاتهم، فضلاً عن تمثيلها الواسع للكيفية الدلالية (Deontic Modality).
بالإضافة إلى ذلك، ومن منظور تداولي، فإن دراسة السياق تعني أخذ نوايا الشخصيات وعلاقاتهم وأوضاعهم الاجتماعية وبيئة الكلام وشروط أخرى بعين الاعتبار، وذلك لتحديد التأثيرات والرغبات والأهداف التي تم تحقيقها في المواقف المختلفة.
توصلت الدراسة إلى أن هناك علاقة وثيقة بين السياق واستخدام الأفعال الناقصة الدلالية، وأن معظم هذه الأفعال تُستخدم بصيغة التوجيهات (Directives) والالتزامات (Commissives) في توجيه الكلام نحو المخاطَبين.
شرب الخمر في حالة الطوارئ يسبب التجريم من وجهة نظر فقه المذاهب وقانون العقوبات الإسلامي
Authors: اغايي سيد رسول , سرخاني عادل
Published: February 2023

الظهور هو، من بين أمور أخرى، عنوان ثانوي وقاعدة فقهية مرموقة تُستخدم في مجالات مختلفة من الفقه والقانون. واحدة من الحالات التي تُعتبر بمثابة ظهور هي شرب الخمر للتخفيف من العطش أو للعلاج. هناك اختلافات بين الفقهاء الإمامية والسنّة حول جواز أو عدم جواز شرب الخمر في حالات الظهور.
من بين القوانين الجنائية، تناولت المادة 152 من قانون العقوبات الإسلامي هذا النوع من الظهور. فما هو الموقف الفقهي من جواز أو عدم جواز شرب الخمر في حالات الظهور؟ وهل يمكن تجريم شرب الخمر في هذه الحالة؟ في الدراسة الحالية، باستخدام المنهج الوصفي التحليلي والنهج المقارن، تم محاولة إعادة قراءة وتحليل آراء الفقهاء الإمامية والسنّة بشأن شرب الخمر في حالات الظهور، ثم مقارنة هذه الآراء مع قانون العقوبات الإسلامي.
وفي النهاية، استنادًا إلى الأدلة العامة من القرآن الكريم والحديث، وبالنظر إلى أن الظهور هو عنوان ثانوي، توصلت الدراسة إلى أنه إذا شرب شخص الخمر في حالة طارئة، فلا يمكن قانونيًا اعتبار أي عقوبة جزائية ضده. ويُستدل على هذا الاستنتاج من المادة 152 من قانون العقوبات الإسلامي.

Published: February 2023

he variety of applications, in all industrial fields, whether for routine use or a specific application, requires the design of increasingly efficient sealing systems. O-rings are fundamental elements in many industrial devices and machines, thanks to advantages such as low cost, small size, cleanliness, and ease of assembly. Moreover, the O-ring is available in thousands of dimensions. In this work, the analysis of the mechanical and leakage behavior of the O-ring seal, when installed either in a groove or between two plates, is presented. The behavior of the assemblies in both scenarios when the clamping force and fluid pressure are applied is investigated using two numerical models generated with Ansys software. The numerical model findings are compared to the analytical approach based on Hertz contact theory and other researchers' experimental results. This study shows that the use of a groove to ensure the mounting of elastomeric O-rings is important in pressurized installations. Furthermore, for different pressure conditions, the reliability of the O-ring strongly depends on three parameters: compression ratio of the seal, the hardness of the seal, and the friction coefficient.

Cyclodextrins as eminent constituents in nanoarchitectonics for drug delivery systems
Authors: Komiyama Makoto
Published: February 2023

Cyclodextrins have been widely employed for drug delivery systems (DDSs) in which drugs are selectively delivered to a target site in the body. Recent interest has been focused on the construction of cyclodextrin-based nanoarchitectures that show sophisticated DDS functions. These nanoarchitectures are precisely fabricated based on three important features of cyclodextrins, namely (1) the preorganized three-dimensional molecular structure of nanometer size, (2) the easy chemical modification to introduce functional groups, and (3) the formation of dynamic inclusion complexes with various guests in water. With the use of photoirradiation, drugs are released from cyclodextrin-based nanoarchitectures at designated timing. Alternatively, therapeutic nucleic acids are stably protected in the nanoarchitectures and delivered to the target site. The efficient delivery of the CRISPR-Cas9 system for gene editing was also successful. Even more complicated nanoarchitectures can be designed for sophisticated DDSs. Cyclodextrin-based nanoarchitectures are highly promising for future applications in medicine, pharmaceutics, and other relevant fields.

Published: February 2023

The Korean National Health Information Database (NHID) contains big data combining information obtained from the National Health Insurance Service and health examinations. Data are provided in the form of a cohort, and the NHID can be used to conduct longitudinal studies and research on rare diseases. Moreover, data on the cause and date of death are provided by Statistics Korea. Research and publications based on the NHID have increased explosively in the field of endocrine disorders. However, because the data were not collected for research purposes, studies using the NHID have limitations, particularly the need for the operational definition of diseases. In this review, we describe the characteristics of the Korean NHID, operational definitions of endocrine diseases used for research, and an overview of recent studies in endocrinology using the Korean NHID.

The TESS mission produces a large amount of time series data, only a small fraction of which contain detectable exoplanetary transit signals. Deep-learning techniques such as neural networks have proved effective at differentiating promising astrophysical eclipsing candidates from other phenomena such as stellar variability and systematic instrumental effects in an efficient, unbiased, and sustainable manner. This paper presents a high-quality data set containing light curves from the Primary Mission and 1st Extended Mission full-frame images and periodic signals detected via box least-squares. The data set was curated using a thorough manual review process then used to train a neural network called Astronet-Triage-v2. On our test set, for transiting/eclipsing events, we achieve a 99.6% recall (true positives over all data with positive labels) at a precision of 75.7% (true positives over all predicted positives). Since 90% of our training data is from the Primary Mission, we also test our ability to generalize on held-out 1st Extended Mission data. Here, we find an area under the precision-recall curve of 0.965, a 4% improvement over Astronet-Triage. On the TESS object of interest (TOI) Catalog through 2022 April, a shortlist of planets and planet candidates, Astronet-Triage-v2 is able to recover 3577 out of 4140 TOIs, while Astronet-Triage only recovers 3349 targets at an equal level of precision. In other words, upgrading to Astronet-Triage-v2 helps save at least 200 planet candidates from being lost. The new model is currently used for planet candidate triage in the Quick-Look Pipeline.
Perihelion Activity of (3200) Phaethon is Not Dusty: Evidence from STEREO/COR2 Observations
Authors: Hui 許 Man-To 文韜
Published: February 2023

We present an analysis of asteroid (3200) Phaethon using coronagraphic observations from 2008 to 2022 by the COR2 cameras onboard the twin Solar TErrestrial RElations Observatory spacecraft. Although undetected in individual images, Phaethon was visible in stacks combined from the same perihelion observations, yet only at small (≲30°) but not large (≳150°) phase angles. The observations are in line with the contribution from a bare nucleus, thereby seriously contradicting the interpretation based on HI-1 observations that attributes the perihelion activity to the ejection of μm-sized dust. We obtained an upper limit to the effective cross section of μm-sized dust to be ≲105 m2, at least three orders of magnitude smaller than earlier estimates based on HI-1 data. On the contrary, the COR2 observations cannot rule out the existence of mm-sized or larger debris around Phaethon. However, the fact that no postperihelion debris tail has ever been detected for Phaethon suggests the unimportance of such dust in the perihelion activity. We thus conclude that the perihelion activity of Phaethon is highly unlikely relevant to the ejection of dust. Rather, we deduce that the activity is associated with gas emissions, possibly Fe i and/or Na D lines. To verify our conjecture and to fully understand the perihelion activity of Phaethon, more observations at small heliocentric distances are desired. We compile a list of observing windows ideal for the search of gas emissions of the asteroid from ground telescopes. The best opportunities will be during total solar eclipses.

Both planets notably have high transmission spectroscopy metrics of 36 and 32, making TOI 4342 one of the best systems for comparative atmospheric studies. This system demonstrates how improvements to QLP, along with faster cadence full-frame images, can lead to the discovery of new multiplanet systems.
Far-ultraviolet Dust Extinction and Molecular Hydrogen in the Diffuse Milky Way Interstellar Medium

Published: February 2023

We aim to compare variations in the full-UV dust extinction curve (912–3000 Å), with the H i/H2/total H content along diffuse Milky Way sightlines, to investigate possible connections between ISM conditions and dust properties. We combine an existing sample of 75 UV extinction curves based on IUE and FUSE data, with atomic and molecular column densities measured through UV absorption. The H2 column density data are based on existing Lyman–Werner absorption band models from earlier work on the extinction curves. Literature values for the H i column density were compiled, and improved for 23 stars by fitting a Lyα profile to archived spectra. We discover a strong correlation between the H2 column and the far-UV extinction, and the underlying cause is a linear relationship between H2 and the strength of the far-UV rise feature. This extinction does not scale with H i, and the total H column scales best with

instead. The carrier of the far-UV rise therefore coincides with molecular gas, and further connections are shown by comparing the UV extinction features to the molecular fraction. Variations in the gas-to-extinction ratio

correlate with the UV-to-optical extinction ratio, and we speculate this could be due to coagulation or shattering effects. Based on the H2 temperature, the strongest far-UV rise strengths are found to appear in colder and denser sightlines.
Long-term Protoplanetary Disk Evolution from Molecular Cloud Core Collapse and Implications for Planet Formation. II. Strong Disk Self-gravity
Authors: Wang Xin-Ming
Published: February 2023

We continue to investigate long-term protoplanetary disk evolution and focus on the situation of strong disk self-gravity (DSG). We call such a disk a type III disk. A large amount of mass is stored in the disk due to large angular momentum. When the disk becomes massive enough, a dense region (DR) is formed due to gravitational instability. This instability is triggered by the combined effect of radial gravitational attraction and a decrease in disk scale height. Viscosity cannot smooth out the DR due to strong DSG. We further investigate the subsequent disk evolution under the assumption of axisymmetry. Besides the viscous process, angular momentum flux caused by the perturbation of DSG also plays a role in the transport of angular momentum. The combination of the two processes results in the efficient transport of angular momentum in the outer disk and prevents the disk from becoming very massive. Due to the interaction between the DR and the inner disk, a gap between them is formed. This gives a nonplanetary origin of the gap. In ∼106 yr, a surface density plateau and a very low surface density region are formed in the inner disk. In a type III disk, there are several locations where the radial drift of solids can be stopped. Objects formed in the DR may remember some of the properties of the DR, such as large mass and large angular momentum. In particular, a planetary system with wide-orbit giant planets may be formed in the DR. Finally, it is still difficult to identify what type of disk the solar nebula belongs to.
Enhanced Star Formation Efficiency in the Central Regions of Nearby Quasar Hosts

Published: February 2023

We combine Atacama Large Millimeter/submillimeter Array and Multi Unit Spectroscopic Explorer observations tracing the molecular gas, millimeter continuum, and ionized gas emission in six low-redshift (z ≲ 0.06) Palomar–Green (PG) quasar host galaxies to investigate their ongoing star formation at roughly kiloparsec-scale resolution. The AGN contribution to the cold dust emission and the optical emission-line flux is carefully removed to derive spatial distributions of the star formation rate (SFR), which, complemented with the molecular gas data, enables the mapping of the depletion time (t
dep). We report ubiquitous star formation activity within the quasar host galaxies, with the majority of the ongoing star formation occurring in the galactic center. The rise of the SFR surface density (ΣSFR) toward the nucleus is steeper than that observed for the cold molecular gas surface density, reaching values up to ΣSFR ≈ 0.15–0.80 M
⊙ yr−1 kpc−2. The gas in the nuclear regions is converted into stars at a shortened depletion time (t
dep ≈ 0.2–2.0 Gyr), suggesting that those zones can be deemed as starbursts. At large galactocentric radius, we find that the ongoing star formation takes place within spiral arms or H ii region complexes, with an efficiency comparable to that reported for nearby inactive spirals (t
dep ≈ 1.8 Gyr). We find no evidence of star formation activity shutoff in the PG quasar host galaxies. On the contrary, these observations shed light on how the central environments of galaxies hosting actively accreting supermassive black holes build up stellar mass.
GRMHD Simulations of Neutron-star Mergers with Weak Interactions: r-process Nucleosynthesis and Electromagnetic Signatures of Dynamical Ejecta
Authors: Combi Luciano , Siegel Daniel M.
Published: February 2023

Fast neutron-rich material ejected dynamically over ≲10 ms during the merger of a binary neutron star (BNS) can give rise to distinctive electromagnetic counterparts to the system’s gravitational-wave emission that serve as a “smoking gun” to distinguish between a BNS and an NS–black hole merger. We present novel ab initio modeling of the kilonova precursor and kilonova afterglow based on 3D general-relativistic magnetohydrodynamic simulations of BNS mergers with nuclear, tabulated, finite-temperature equations of state (EOSs), weak interactions, and approximate neutrino transport. We analyze dynamical mass ejection from 1.35–1.35 M
⊙ binaries, consistent with properties of the first observed BNS merger GW170817, using three nuclear EOSs that span the range of allowed compactness of 1.35 M

A boost in early UV/optical brightness by a factor of a few due to previously neglected relativistic effects, with enhancements up to ≲10 hr post-merger, is promising for future detection with UV/optical telescopes like Swift or ULTRASAT. We find that a recently predicted opacity boost due to highly ionized lanthanides at ≳70,000 K is unlikely to affect the early kilonova based on the obtained ejecta structures. Azimuthal inhomogeneities in dynamical ejecta composition for soft EOSs found here (“lanthanide/actinide pockets”) may have observable consequences for both early kilonova and late-time nebular emission.

In this work, we present 299 candidate young stellar objects (YSOs) in 30 Doradus discovered using Spitzer and Herschel point-source catalogs, 276 of which are new. We study the parental giant molecular clouds in which these YSO candidates form using recently published Atacama Large Millimeter/submillimeter Array (ALMA) Cycle 7 observations of 12CO and 13CO. The threshold for star formation in 30 Doradus inferred by the LTE-based mass surface density is 178 M
⊙ pc−2, 40% higher than the threshold for star formation in the Milky Way. This increase in star formation threshold in comparison to the Milky Way and increase in line width seen in clumps 11 pc away in comparison to clumps 45 pc away from the R136 super star cluster could be due to injected turbulent energy, increase in interstellar medium pressure, and/or local magnetic field strength. Of the 299 YSO candidates in this work, 62% are not associated with 12CO molecular gas. This large fraction can be explained by the fact that 75%–97% of the H2 gas is not traced by CO. We fit a Kroupa initial mass function to the YSO candidates and find that the total integrated stellar mass is 18,000 M
⊙ and that the region has a star formation rate (SFR) of 0.18 M
⊙ yr−1. The initial mass function determined here applies to the four 150″ × 150″ (37.5 pc × 37.5 pc) subfields and one 150″ × 75″ (37.5 pc × 18.8 pc) subfield observed with ALMA. The SFR in 30 Doradus has increased in the past few million years.
