A Study of the Jungshan Kingdom
Authors:   The Academy of Real Korean History, Song Giseop
Published: July 2023

Jungshan Kingdom is Sun-woo's successor. The reason for this is that you can see this by looking at the names given to them in the records of historical books. In other words, it was mixed with Baekjeok and Seonwoo in the early days of Chunchu, and Seonwoo and Jungsan in the late Chunchu, and Jungshan was called Jungshan in the Jeonguk Dynasty, and it is said that Jungshan was named because there was a mountain in Junginseong Fortress where Seonwoo moved to the capital.
Seonwoo and Jungshan first appear in Jwagumyeong's “Jwajeon” in the librarian's record. This period corresponds to the beginning of Choonchoo in 774 BC. It continued for nearly 500 years until the fall of the Jungshan Kingdom by the Zhao Dynasty in 296 BC. And in the Warring States Period, Jungshan had strong national taxes enough to be called Jeongook8ung in an era. Nevertheless, historical records such as “Jwajeon”, “Gookeo” and “Jeonrookchaek”, “Sagee” were recorded in fragments, Therefore, research on this was insufficient, and even the research relied on estimation, but there were many irrational tendencies.
However, in the 1970s, the excavation of relics in Seokgajang area allowed us to confirm the reality of Jungshan Kingdom, and scholars' interest increased, and since then, research has been conducted from various angles. The paper also described the background of the formation of Seonwoo and Jungshan Kingdom, the reality of the people, the location of Junghsan Kingdom, the rise and fall of Jungshan Kingdom, and until the Jungshan after the fall, I tried to approach and understand the reality of the middle mountain country with universality and rational description. A summary of the contents of this paper is as follows.
The first is to find out who they are. In this regard, Yang Ok-seung, who denied the theory of being a descendant of the Zhou Dynasty, but insisted on the theory of Baekjeok, agreed and followed it. Regarding the reality of Hanjok and Dongijok, it helped to understand by publishing “Oje and Ha, Eun, Ju's Sijo Genealogy” by the Sagi Research Institute of the Hangaram Historical and Cultural Institute, which identified this.
Second, where did you live? It is believed that Baekjeok established power in the current Seomseo and Naemongo areas north of Sanseo and entered the Sanseo and Habuk areas beyond the current Sakju and Anmungwan, and the period of movement was before 774 BC.
Third, it is 'the varied fortunes of races.' of Jungshan Kingdom. From the study of Jungshanmungong to the time when the last monarch 'Sang' was conquered by King Muryeong of the Zhao Dynasty, Mugong settled in Go, and the twists and turns of Buchim continued, but at one time, the national tax was strong enough to win the title of the king.
Fourth, after the fall of the Jungshan Kingdom, we looked at the path of the name Jungshan from the Qin Dynasty to the Tang Dynasty. The name Jungshan was maintained as an administrative unit of Hangsan or Sangshan, but the name Jungshan was generally used.
Kim Dong-sam and The National Representative Conference
Authors:   The Academy of Real Korean History, Lee Deokil
Published: July 2023

The Provisional Government of the Republic of Korea was born as a result of the March 1st Revolution in 1919. However, as various problems were revealed, a view to find a solution emerged. As a result, from January 3 to June 7, 1923, the National Representative Conference was held in Shanghai attended by 125 delegates. The two lines collided. Reformation theory that recognized the Provisional Government and extensive reforms, and Creationism that the Provisional Government should be dissolved and reorganized. Kim Dongsam, a reformist, was elected as the chairman, and Yoon Hae, a creationist, was elected as the vice-chairman.
At the National Representative Conference, the Reform faction had a numerical superiority. However, the Creationists prevented the reform agenda from being adopted in a way that hindered the progress of the conference. On May 15, when Kim Dong-sam was recalled from Manchuria's West Road Military Administration and the Korean People's Club, which dispatched Kim Dong-sam, Kim Dong-sam resigned as chairman. Vice Chairman Yoon Hae became the chairman. On June 7, only the Creationists got together and passed a new constitution, but it was an agreement of their own faction. The Conference was held by the consensus of the entire nation, ended without any results. However, it was an event worthy of becoming a milestone in Korean democracy in that representatives of the entire nation gathered to discuss the future of the nation.
Exploratory Investigation of Scope Management for a BIM-enabled Construction Project
Authors:   KINFORMS/KAABA, Kim Ki Pyung , Ma Tony , John Biddiss
Published: July 2023

Despite the recommendation of the international BIM standard ISO 19650, the current scope management process and practice for a BIM-enabled project need to be improved for the full benefits of the BIM adoption. Due to a lack of clarity in BIM-enabled project scope definition and roles and responsibilities for project key participants, unnecessary reworks and various change orders are occurred in the project execution phase. To minimise reworks and improve productivity, it is essential to understand the status of BIM-enabled project scope management practice. However, the current practice of scope management in a BIM-enabled project environment has been rarely studied. Thus, the research aims to identify the current scope management practice for BIM-enabled construction projects via interviews. It is revealed that the current scope definition process fails to provide clear roles and responsibilities for a BIM manager and a project manager separately. Additionally, the disconnection between the PIM and AIM causes ineffectiveness of utilising lessons learned for scope definition. The research findings will contribute to providing insights to improve the current scope management practice more suitable for a BIM-enabled project.

Published: July 2023

A study was conducted for estimating genetic parameters involving 10 parents and their 45 F1s (half diallel) of bread wheat (Triticum aestivum L.) der timely sown condition of north western plains zone of India during 2011-12 and 2012-13. Positive and significant values of F component were estimated for yield and its contributing traits in F1s indicating the preponderance of dominance and positive genes in the parents involed. The estimates of h2 were positive and significant for days to maturity (2.97), plant height (28.14), peduncle length (5.48), productive tillers (0.55), spike length (0.76), spikelets/spike (26.28), grains/spike (228.45), biological yield (149.71), grain yield (73.58), harvest index (33.15), and 1 000 grain weight (21.71). The theoretical value (0.25) of (H2/4H1) for all the traits indicated asymmetrical distribution of positive and negative genes. The proportion of dominant and recessive alleles for days to 50% flowering, days to maturity, plant height, peduncle length, productive tillers, spike length, biological yield, grain yield, harvest index and 1 000 grain weight, indicated preponderance of dominant alleles in the parents for these traits, whereas traits namely; flag leaf area, spikelets/spikes, grains/spike and gluten content, reflected more recessive alleles in the parents. Estimates of SCA effects revealed that the best cross combinations for respective traits were K 9162 × UP 2425, PBW 373 × UP 2425, K 9423 × Unnat Halna, K 9423 × HUW 560, Raj 3765 × NW 1014, K 9423 × NW 1014, NW 1014 × NW 1076, Raj 3765 × PBW, K 9423 × NW 1076, Raj 3765 × NW 1076, Raj 3765 × Unnat Halna and Unnat Halna x HUW 560 may be exploited through heterosis breeding programme to improve these traits in bread wheat. The traits showing more than 30% narrow sense heritability could be rewarding for further improvement of grain yield and gluten content in bread wheat. It may therefore be concluded that these parental lines could be used as donors for improving both the components following biparental mating or diallel selective mating system could be the best breeding methodology followed by early generation selection for improvement in these traits.

The aim of this preliminary study was to evaluate the effects of two emotional education programmes in a charter school in Donostia-San Sebastián, Spain, on students’ emotional competence and the social climate in the classroom. A quasi-experimental pretest-posttest repeated measures design with a control group was utilized in the study. The participants in the study were 105 students in Year 6 of primary school and Year 2 of secondary school. The Emotional Development Questionnaire (EDQ) and the Classroom Social Climate Scale (CES) were used to assess the effect of the intervention. The results indicate that the ‘Sentituz 10-12’ programme is effective in improving students’ social competence and the quality of student-teacher relationships, whereas the ‘Sentituz 12-14’ programme is effective in promoting the emotional autonomy and overall emotional competence of students. This was however, a small scale preliminary study, and further and more rigorous studies are also need in order to evaluate the impact of these two emotional education programmes.

Analysis of the ocean dynamics in a wind-jet region using high-resolution models
Authors:   , Ràfols Bundó Laura
Published: July 2023

The water currents and the wave field at the Catalan coast (in the Northwestern Mediterranean Sea) are investigated. However, the main research is focused at the northern margin of the Ebro Shelf, where there is a relatively high amount of data for study purposes and where episodes of strong northwesterly wind occur. In such cases, the wind is channeled through the Ebro Valley and intensifies upon reaching the sea, resulting in a wind jet.

The research has been divided into four parts: (1) the study of the water circulation induced by a wind jet, by means of the Regional Ocean Modeling System (ROMS) numerical model; (2) the study of the waves dynamics induced by a wind jet, using the Simulating WAves Nearshore (SWAN) numerical model; (3) the study of the wave-current interactions during wind-jet events, coupling the numerical models used formerly; and (4) the implementation and validation of a waves and currents forecasting system at the Catalan coast, based on the knowledge gained during the research performed in the previous parts.

S'investiguen els corrents marins i l'onatge a la costa catalana (al nord-oest del Mar Mediterrani). Tanmateix, la recerca principal es centra al marge nord de la plataforma de l'Ebre, on hi ha una quantitat relativament alta de dades útils per a la investigació i on tenen lloc episodis de fort vent del nord-oest. En aquests casos, el vent és canalitzat al llarg de la vall de l'Ebre i s'intensifica quan arriba al mar, resultant en un wind jet. La investigació s'ha dividit en quatre parts: (1) l'estudi de la circulació de l'aigua induïda per un wind jet, utilitzant el model numèric Regional Ocean Modeling System (ROMS); (2) l'estudi de l'onatge induït per un wind jet, mitjançant el model numèric Simulating WAves Nearshore (SWAN); (3) l'estudi de les interaccions onatge-corrents durant episodis de wind jet, acoblant els models numèrics utilitzats anteriorment; i (4) la implementació i validació d'un sistema de predicció d'onatge i corrents a la costa catalana, basat en el coneixement adquirit durant la recerca realitzada en les parts anteriors.
Hydro-mechanical analysis of expansive clays : constitutive and numerical modelling.
Authors:   , Ruiz Restrepo Daniel Felipe
Published: July 2023

Bentonite-based materials are being currently considered in several countries as a backfill component in the multi-barrier concept for deep geological disposal of radioactive waste. The bentonite barrier fulfils several important functions: i) high swelling capacity to fill gaps and compress the excavation damaged zone and ii) very low hydraulic conductivity and important retention capacity which retards significantly radionuclides transport. Small-scale testing in geotechnical laboratories and in-situ experiments in underground research laboratories (URL) have demonstrated that initial state, water supply conditions and volume constrictions are the main aspects affecting the behaviour of bentonites.
In this context, the main objective of the present study is the numerical simulation of the hydro-mechanical behaviour of expansive clays. For this purpose, a constitutive model has been developed to characterise the bentonite-based materials. The modelling of these materials is a quite challenging task. They exhibit a marked double-porosity system in which the swelling/shrinkage mechanism occurs at clay aggregate level and the collapsible behaviour comes from granular-like skeleton formed by the aggregates. In addition, several material configuration, with even more intricate fabric, have been proposed for the emplacement works of seals and plugs. The explicit consideration of two structural levels for the constitutive model seems to be suitable. Mechanical interaction and water mass exchanges between them can explain the short- and long-term behaviour. The model has been formulated using concepts of elasto-plasticity for strain hardening materials and generalized plasticity theory. The formulation has been implemented in the finite element code program CODE-BRIGHT and has been used to solve a variety of problems. The results provide relevant insights into the hydro-mechanical behaviour of double structure porous media, and they indicated the main aspects affecting the responses of expansive barriers. In particular, the relevance of the structural levels interaction has been demonstrated.

Authors: Evandio Rafifrian
Published: July 2023

Penelitian ini menjelaskah tentang strategi branding politisi perempuan dengan merujuk pada studi kasus strategi personal branding Puan Maharani Nakshatra Kusyala Devi sebagai “cucu Bung Karno” dan “putri Megawati Soekarnoputri”. Sosok Puan Maharani sendiri dikenal oleh publik Indonesia sebagai putri tunggal dari Megawati Soekarnoputri dengan suami ketiganya, Muhammad Taufiq Kiemas. Dengan statusnya tersebut, sosok Puan Maharani sering kali diasumsikan oleh berbagai kalangan sebagai suksesor dari trah atau keturunan Soekarno (Bung Karno) selaku kakeknya. Rampersad yang mengungkapkan bahwa setiap orang pada umumnya cenderung memiliki sebuah brand, namun sebagian besar orang tidak menyadarinya dan tidak mengelolanya secara strategis, konsisten, dan efektif. Hal ini akan membantu seseorang untuk mampu berkembang dan membedakan diri dengan orang lain. Pasalnya, konsep personal branding sendiri setidaknya dapat dimaknai lebih dari sekedar memasarkan dan mempromosikan diri. Bahkan, personal branding merupakan sintesis dari semua pengharapan, citra dan persepsi yang diciptakan dalam pemikiran orang lain sewaktu mereka membaca atau mendengar nama seseorang. Selain itu, Rampersad juga menyebutkan bahwa brand yang dimiliki oleh seseorang haruslah otentik; merefleksikan karakter yang sebenarnya; dan diciptakan berdasar pada nilai-nilai yang dipegang oleh seseorang, keunggulan, keunikan, dan kepandaian orang tersebut. Untuk memperoleh data, penelitian ini menggunakan data sekunder yang diperoleh dari studi terhadap literatur-literatur yang relevan. Hasil penelitian ini memperlihatkan bahwa Puan Maharani Nakshatra Kusyala Devi berhasil membangun personal branding sebagai salah satu sosok politisi perempuan yang berhasil terlibat dalam politik dengan turut didukung penggunaan citra sebagai “cucu Bung Karno” dan “putri Megawati Soekarnoputri” sebagai brand yang melekat pada dirinya.
Discussion of some methods of quantifying exchange rate risk
Authors:   Banking Academy of Vietnam, Nguyễn Văn Tiến
Published: July 2023

Exchange rate is the price of one currency expressed in terms of another currency. The fluctuation of the exchange rate depends on both domestic factors and foreign factors, in which changes in interest rate policies of central banks become a factor that causes exchange rates to fluctuate rapidly, significantly, and unpredictably. From the beginning of 2022 up to now, inflation has been exploded all over the world, including the US, EU and developed countries, forcing central banks to apply tight monetary policies by raising interest rates. During the period from the beginning of 2022 until now, the US Federal Reserve (Fed) has raised interest rates 8 times with a very high frequency and great intensity, causing the USD to be appreciated against most currencies, including VND. When the exchange rate fluctuates, it will affect almost all of economic activities such as import-export activities, foreign investment, international trade competitiveness, and even businesses and consumers that do not generate receipts or payments in foreign currency. Therefore, the study of measurement of exchange rate risks has become increasingly important from the perspectives of both theory and practice

El estudio tuvo como objetivo determinar la diversidad de anuros, en la zona de amortiguamiento de la Reserva Ecológica Cofán Bermejo, Parroquia El Dorado de Cascales y establecer si presenta alguna variación en un gradiente altitudinal (tres pisos). En la búsqueda de técnicas de anuros se utilizó como encuesta de encuentro visual y transectos, identificando cinco transectos altitudinales para cada piso. Se registraron 71 individuos, pertenecientes a 30 especies, presentando una variedad de Shannon promedio (3.15 bits), de acuerdo con la escala sugerida por (Valle, 2001). Las especies más abundantes fueron: Rhinella marina, Hyloxalus bocagei and Rhinella margaritífera and less dominant, Dendropsophus rhodopeplus, Engystomops peterse, Lithodytes lineatus, Hypodactylus nigrovittatus, Pristimantis delius, Pristimantis matidiktyo, Pristimantis prolatus, Pristimantis sp., Rhinella festae and Synapturanus rabus. En el primer piso altitudinal de 400-600 metros sobre el nivel del mar, se registraron 30 individuos de 12 especies. En la altitud del segundo piso 600-800 metros sobre el nivel del mar, se registraron 16 individuos de nueve especies. En el tercer piso altitudinal 800 -1000 metros sobre el nivel del mar, se registraron 25 individuos de 14 especies, lo que demuestra la preferencia de la especie para altitudes más altas, la diversidad según Shannon de anuros es baja con valores que varían de 1,99 a 2,48 bits. Se plantea la solución alternativa, como la gestión del manejo de la zona de amortiguamiento de la Reserva Ecológica Cofán Bermejo, emitiendo ordenanzas y reglamentos y actividades educativas, que permitirán la conservación de los bosques, los hábitats donde se desarrollan las especies y la conservación de la diversidad de anuros.

Women and Sculptures: Femininity in Hart Crane’s Ekphrastic Poems
Authors: Piechucka Alicja
Published: July 2023

The article explores two poems by Hart Crane, “Interludium” and “To the Empress Josephine’s Statue,” both of which are examples of ekphrasis. Inspired by two sculptures of women, Gaston Lachaise’s La Montagne and Vital Debray’s statue of Joséphine de Beauharnais, the poems in question are at once representations of works of art and of femininity. It is as such that they are scrutinized in an analysis which focuses on poetry, the visual arts and femininity. The article deals with Crane’s use of ekphrasis as a genre, but also with his resections on time and space, the domains of poetry and sculpture respectively. It also delves into a number of connections evidenced in “Interludium” and “To the Empress Josephine’s Statue”: the one between creation and procreation, understood as maternity, and thus between art and femininity, as well as the ones between femininity on the one hand, and nature, mysticism, morality and history on the other.
An Assessment of Students’ Self-Regulated Learning of a Higher Education Institution in a Highly Urbanized City in the Philippines
Authors: De Manuel Joanna Marie Pina
Published: July 2023

Nowadays, learners have found various ways to learn individually through available technologies. Moreover, with the pandemic where flexible learning was implemented and a modular approach was utilized, the students had a hard time taking the initiative to study independently and setting goals in their academic endeavors. Students cannot manage the information they get; they have difficulties critically analyzing the important information they need. Thus, they should be properly guided on self-regulated learning since the curricula nowadays are student-centered. The study aimed to assess the self-regulated learning level of the 2nd-4th year students of the Pamantasan ng Lungsod ng Pasig in terms of planning, monitoring, controlling or adjusting, and reflecting. The study adopted the descriptive method with 2,302 respondents from the five colleges. Based on the findings, the students have a moderate level of self-regulated learning. Moreover, there is a significant difference in the self-regulated learning of the students when grouped according to their sex, age, college level, program, units enrolled, and weekly allowance. However, there is no significant difference in their self-regulated learning according to their academic status and scholarship. In addition, there is a significant relationship between the self-regulated learning level and academic performance of the student-respondents of PLPasig. It is recommended that students must be exposed to more complex, open-ended tasks that will make them practice managing distractions and maintaining focus while tackling increasingly challenging academic work.
School Safety and Infrastructure Compliance to Requirements of Face-To-Face Classes of the Selected Public Secondary Schools
Authors: Galgo Avelina , Curaza Lydia Josefina
Published: July 2023

Huge differences were expected in the new normal learning, and a significant transition was needed.   While the implementation of face-to-face classes was still at the infant stage, it is very important to know the challenges of the school heads so that actions can be taken in a timely fashion. The study aimed to determine the school safety and infrastructure compliance to requirements for face-to-face classes of the selected public secondary schools in Butuan City Division. A mixed-method approach was used in the study, which was considered an appropriate approach considering the nature of the data gathered and the objectives of interest. The School Safety Assessment Tool (SSAT) was used to determine the level of readiness of schools in preparation for the safe re-opening of classes, which provided the necessary information on the improvements and adjustments to be made before the implementation of face-to-face classes. An interview guide was designed to determine the experiences and practices of school principals in relation to school management during the pandemic. Strict adherence to necessary guidelines is major preparation for schools to secure permits for the full implementation of face-to-face classes. Information drive and collaboration with stakeholders increase the sustainability aspect of face-to-face implementation. Schools have taken measures to ensure the safety of children who will be attending in-person classes, such as masks and other PPE policies for teachers, school staff, and students by national and local guidelines to enhance hygiene measures and adequate handwashing facilities, frequent cleaning of surfaces and shared objects, appropriate ventilation.
Chitosan Application in Aquatic Feed and Its Impact on Fish and Shrimp Productivity
Authors: Andriani Yuli , Pratama Rusky I. , Hanidah In In
Published: July 2023

The culture of crustaceans, such as shrimp and crabs, in Indonesia has resulted in a significant increase in waste production, particularly in the form of shells and heads. This waste contains valuable components like chitin, chitosan, and carotenoids, which can be extracted and utilized in aquaculture activities. Some research results show that the use of chitosan, derived from chitin, in fish feed, is a functional polysaccharide with various biological activities, including antimicrobial, anti-inflammatory, and immune-stimulating effects. It also acts as a growth promoter in shrimp and improves the performance of farmed fish. Additionally, the inclusion of chitin and chitosan in fish feed formulations enhances digestibility, growth, and nutrient absorption. This paper provides a comprehensive review of the potential, nutritional value, and benefits of processed crustacean waste products, focusing on chitosan, and their impact on the productivity of fish in aquaculture.

Direct deposition of organic light‐emitting diodes (OLEDs) on silicon‐based complementary metal–oxide–semiconductor (CMOS) chips has enabled self‐emissive microdisplays with high resolution and fill‐factor. Emerging applications of OLEDs in augmented and virtual reality (AR/VR) displays and in biomedical applications, e.g., as brain implants for cell‐specific light delivery in optogenetics, require light intensities orders of magnitude above those found in traditional displays. Further requirements often include a microscopic device footprint, a specific shape and ultrastable passivation, e.g., to ensure biocompatibility and minimal invasiveness of OLED‐based implants. In this work, up to 1024 ultrabright, microscopic OLEDs are deposited directly on needle‐shaped CMOS chips. Transmission electron microscopy and energy‐dispersive X‐ray spectroscopy are performed on the foundry‐provided aluminum contact pads of the CMOS chips to guide a systematic optimization of the contacts. Plasma treatment and implementation of silver interlayers lead to ohmic contact conditions and thus facilitate direct vacuum deposition of orange‐ and blue‐emitting OLED stacks leading to micrometer‐sized pixels on the chips. The electronics in each needle allow each pixel to switch individually. The OLED pixels generate a mean optical power density of 0.25 mW mm−2, corresponding to >40 000 cd m−2, well above the requirement for daylight AR applications and optogenetic single‐unit activation in the brain.

The optical features of multiple‐layered axial heterostructures composed of III‐nitride semiconductors (GaN, InGaN, and AlGaN) are investigated to realize tunable nanolasers. The optical confinement effects develop exciton‐polariton in nanorods, leading to polariton lasing with distinctive dispersion. The lasing characteristics in the heterostructure are similar to those in the homostructure, although the carrier transfer between layers influences the optical gain. The energy‐dependent property of polariton changes the mode spacing of lasing peaks. The alloyed systems of InGaN can tune the color of lasing in the visible region, while the lasing of AlGaN is also achievable in the optimized configuration. The polarization of lasing indicates the predominant contribution of the fundamental transverse mode. Therefore, in the multiple‐layered heterostructure, controllable triple‐color lasing using the feature of polariton, modulation of band gap energy, and the amplification process of the waveguide is demonstrated for the first time, with the tunable color over a wide range of the visible region. Multicolor polariton nanolasers offer a promising path to diverse nanophotonic devices with controllable optical characteristics.

Published: July 2023

An uncatalyzed three‐component reaction employing aliphatic organozinc reagents for the preparation of α‐substituted β‐ketoesters is described. This modular procedure, which relies on a formal conjugate addition/crossed‐Claisen domino reaction between an organozinc, an acrylate and an acyl chloride, allows the straightforward synthesis of the reaction products under mild conditions. The three‐component coupling can also be conducted from alkyl iodides, in an even more simple procedure. Experimental findings account for a probable polar concerted mechanism involving at least two organozinc compounds at the stage of the transition state.

RNA‐binding proteins (RBPs) play essential roles in tumorigenesis and progression, but their functions in gastric cancer (GC) remain largely elusive. Here, it is reported that Pumilio 1 (PUM1), an RBP, induces metabolic reprogramming through post‐transcriptional regulation of DEP domain‐containing mammalian target of rapamycin (mTOR)‐interacting protein (DEPTOR) in GC. In clinical samples, elevated expression of PUM1 is associated with recurrence, metastasis, and poor survival. In vitro and in vivo experiments demonstrate that knockdown of PUM1 inhibits the proliferation and metastasis of GC cells. In addition, RNA‐sequencing and bioinformatics analyses show that PUM1 is enriched in the glycolysis gene signature. Metabolomics studies confirm that PUM1 deficiency suppresses glycolytic metabolism. Mechanistically, PUM1 binds directly to DEPTOR mRNA pumilio response element to maintain the stability of the transcript and prevent DEPTOR degradation through post‐transcriptional pathway. PUM1‐mediated DEPTOR upregulation inhibits mTORC1 and alleviates the inhibitory feedback signal transmitted from mTORC1 to PI3K under normal conditions, thus activating the PI3K–Akt signal and glycolysis continuously. Collectively, these results reveal the critical epigenetic role of PUM1 in modulating DEPTOR‐dependent GC progression. These conclusions support further clinical investigation of PUM1 inhibitors as a metabolic‐targeting treatment strategy for GC.

Poly(3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHBH) foams were prepared by a foam injection molding (FIM) process using nitrogen (N2) as a physical blowing agent. PHBH is a marine degradable polymer known for its heat treatment weakness. Gel permeation chromatography and rheological measurements showed that the molecular weight was reduced when the polymer was processed at a temperature higher than 160°C; however, it had a prominent melt memory of crystallization at a temperature lower than 170°C. The melt memory effect increased the crystallization temperature and provided crystal nucleation sites, which became bubble nucleation sites in the foaming process. Microcellular foams, whose cell size is smaller than 30 μm and cell density is higher than 3 × 108 cells cm−3, were prepared using the melt memory effect while suppressing the thermal decomposition by tuning the injected polymer's temperature (melting temperature) and the core‐back timing. The mechanical properties of the resulting foams were evaluated, indicating that a high ductility PHBH microcellular foam was obtained at a melting temperature of 150°C.

Mn2+ complexes of 2,4‐pyridyl‐disubstituted bispidine ligands have emerged as more biocompatible alternatives to Gd3+‐based MRI probes. They display relaxivities comparable to that of commercial contrast agents and high kinetic inertness, unprecedented for Mn2+ complexes. The chemical structure, in particular the substituents on the two macrocyclic nitrogens N3 and N7, are decisive for the conformation of the Mn2+ complexes, and this will in turn determine their thermodynamic, kinetic and relaxation properties. We describe the synthesis of four ligands with acetate substituents in positions N3, N7 or both. We evidence that the bispidine conformation is dependent on N3 substitution, with direct impact on the thermodynamic stability, kinetic inertness, hydration state and relaxivity of the Mn2+ complexes. These results unambiguously show that (i) solely a chair‐chair conformation allows for favorable inertness and relaxivity, and (ii) in this family such chair‐chair conformation is accessible only for ligands without N3‐appended carboxylates.

Zinc‐bromine flow batteries (ZBFBs) are promising candidates for the large‐scale stationary energy storage application due to their inherent scalability and flexibility, low cost, green, and environmentally friendly characteristics. ZBFBs have been commercially available for several years in both grid scale and residential energy storage applications. Nevertheless, their continued development still presents challenges associated with electrodes, separators, electrolyte, as well as their operational chemistry. Therefore, rational design of these components in ZBFBs is of utmost importance to further improve the overall device performance. In this review, the focus is on the scientific understanding of the fundamental electrochemistry and functional components of ZBFBs, with an emphasis on the technical challenges of reaction chemistry, development of functional materials, and their application in ZBFBs. Current limitations of ZBFBs with future research directions in the development of high performance ZBFBs are suggested.

Published: July 2023

Toward the challenge on reliable determination of food contaminants to ensure food safety and security, surface‐enhanced Raman spectroscopy (SERS) technology with single‐molecule sensitivity through their “fingerprint” Raman signal has been developed into a fundamental and important molecular toolkit for food industry. Currently, hydrogel is attracting great interests in SERS sensing as a functional and flexible material. In this perspective, we first introduce the classification of common hydrogel and strategies for the synthesis of SERS substrates. Next, we highlight the response characteristics of hydrogel, including temperature response and pH response. Finally, we summarize the applications of hydrogel‐based substrates for food contaminant detection and discuss its developing trends and challenges. Compared to traditional solid SERS substrates, hydrogel‐based substrates have encouraging characteristics, such as unique flexibility to adhere to food surfaces for direct target molecule collection, and the stable three‐dimensional network scaffold that prevents the aggregation of SERS hot spots, etc. These advantages suggest that hydrogel‐based substrates have great potential for food safety analysis and monitoring.
Diurnal proteome profile of the mouse cerebral cortex: Conditional deletion of the Bmal1 circadian clock gene elevates astrocyte protein levels and cell abundance in the neocortex and hippocampus

Circadian oscillators, defined by cellular 24 h clock gene rhythms, are found throughout the brain. Cerebral cortex‐specific conditional knockout of the clock gene Bmal1 (Bmal1 CKO) leads to depressive‐like behavior, but the molecular link from clock gene to altered behavior is unknown. Further, diurnal proteomic data on the cerebral cortex are currently unavailable. With the aim of determining the diurnal proteome profile and downstream targets of the cortical circadian clock, we here performed a proteomic analysis of the mouse cerebral cortex. Proteomics identified approximately 2700 proteins in both the neocortex and the hippocampus. In the neocortex, 15 proteins were differentially expressed (>2‐fold) between day and night, mainly mitochondrial and neuronal plasticity proteins. Only three hippocampal proteins were differentially expressed, suggesting that daily protein oscillations are more prominent in the neocortex. The number of differentially expressed proteins was reduced in the Bmal1 CKO, suggesting that daily rhythms in the cerebral cortex are primarily driven by local clocks. The proteome of the Bmal1 CKO cerebral cortex was dominated by upregulated proteins expressed in astrocytes, including GFAP (4‐fold) and FABP7 (>20‐fold), in both the neocortex and hippocampus. These findings were confirmed at the transcript level. Cellular analyses of astrocyte components revealed an increased number of GFAP‐positive cells in the Bmal1 CKO cerebral cortex. Further, BMAL1 was found to be expressed in both GFAP‐ and FABP7‐positive astrocytes of control animals. Our data show that Bmal1 is required for proper cellular composition of the cerebral cortex, suggesting that increased cortical astrocyte activity may induce behavioral changes.
