Impact of Studying Abroad on English Language Teachers at University Level in Bangladesh
Authors: Hossain Rumana
Published: June 2023

The study addresses an issue regarding the English language teachers who have studied abroad and are teaching at the tertiary level of education in Bangladesh. The idea of this study comes out of my professional experience and my encounter with fellow ELT practitioners. I have been in the field of language teaching for the past fourteen years and at Jahangirnagar University, Dhaka, Bangladesh for the last seven years where I watch my students turning into my colleagues. I noticed that the increasing demand for competent users of English in this era of globalization has also made my colleagues interested in getting education from Western developed countries like their predecessors. Equally has grown the demand for English Language Teaching (ELT) and related studies like Teaching English to Speakers of Other Languages (TESOL). Much investigation has been carried out on the experiences of the teachers while they were studying abroad but no studies have been carried out on the returning teachers and the episode after. This study, thus, is an attempt to explore what prompted these teachers to study abroad, whether these Western trained teachers on their return have made changes to their teaching approaches, how or in what ways have they done it, what sort of obstacles did they face or are they facing and what measures can be taken to overcome these barriers. These issues are central in connection to the future of English language teaching at the university level and based on the opinions of the teachers, the study provides recommendations to bridge the gap between the existing language teaching policy and practice.
An Epistemological Paradox:
Authors: Abedin Manzoorul
Published: June 2023

David Lewis, the author of Bangladesh: Politics, Economy and Civil Society (2012), and LSE Professor of Social Policy and Development, is quite right when he says Bangladesh is little known to the western world except forits pervasive image of a disaster-prone, poverty-stricken and donor-reliant country. The book, in this respect, serves the purpose well as it highlights the considerable progress Bangladesh has made since its independence in 1971, challenging prophecies that the new state would be unviable (12-13). There is acknowledgement that Bangladesh has expanded its food production, developed important new export industries such as readymade garments, improved areas of its healthcare and education, for which Lewis has generally applauded concerted government action and innovative work of some of its NGOs in partnership with donor agencies. By doing so, however, Lewis has opened up the reader to question his authorial stance of the book and his methodology relative to the investigation.
Dissent in Things Fall Apart:
Authors: Fardous Shahrin
Published: June 2023

Widely read and discussed author Chinua Achebe (1930-2013) has created dissent in Okonkwo out of the cultural clash between native African and traditional white culture of the archetypal colonialists — the British traders, missionaries and government officers – in his groundbreaking novel Things Fall Apart (1958). From the very outset, Okonkwo is placed as an acute follower of his tribal customs and norms while dissenting against everything that disagrees with his Igbo heritage. This study aims to ascertain the route of a dissenter by rationalizing Okonkwo’s suicide as an act of ultimate rebellion to remind his people of their traditions and to inspire resistance in the face of impending colonization. The study intends to show Achebe’s projection of Okonkwo as a gradual uprising dissenter, setting up other characters like Unoka, Nwoye, and Obierika and their deeds as a foil to Okonkwo. Through Okonkwo’s resistance, the author insightfully claims that the fall in the title is not the fall of a dissenter, but the rise of an undying rebellious spirit who embraces death instead of accepting British subjugation
Pink and Blue:
Authors: Khan Shehreen Ataur
Published: June 2023

This paper deals with the large scale usage of gender-specific colors in media representation and promotional activities of several products in the consumer world. Irrespective of region and race, the association of the color pink with females and blue with males has become a part of consumer culture worldwide and, consequently,has resulted in a consumerism conditioned by gender. Such a trend is eventually leading to gender stereotypes and sexism among consumers. In this paper, the author gives a brief historical account on gendered consumerism followed by an analysis of the current consumer culture where trends in the entertainment and cosmetics industries are analyzed. The paper discusses the impact of gendered consumerism by presenting an online survey conducted among 200 consumers. It also attempts to propose a few solutions like androgyny and alternative marketing promotions to subvert the fixated color representation.
“WO”man of the People:
Authors: Siddique Rumana
Published: June 2023

Gendered assumptions of nationalism have been an integral part of liberation and post-liberation theory and fiction resulting in the construction of disempowered national identities for women in the modern African states. The narratives of idealization and mythologizing sketch women in the developing literary canvas as symbolic or biological figures who had no active social or political roles or voices. This paper focuses on how gender roles in national identity and nation-building have evolved in the works of the major male African writer Chinua Achebe. It examines the narratives that have reinforced or challenged Achebe with particular focus on how the portrayal of women in his final novel stands him as a progressive in terms of a new vision of the role and space of women in modern Africa.
Using Generic Imagery and Groups to Encourage Student Dialogue
Authors: Price-Jones K. Shelley , Smith Adrian M.
Published: June 2023

This paper evaluates the ongoing effectiveness of a set of EFL classroom materials for use in groups, which were developed to encourage student dialogue in Korean General English university classes. The analysis draws upon retrospective student surveys: two solely quantitative, and one having qualitative, components. This specific lesson was part of the regular curriculum, and taught in exactly the same procedural manner for each research period; utilizing time-efficient social group rotations in combination with innovative materials partially composed of conceptual artwork. By incorporating local culture into the artefacts’ design, students were required to use language in context, and were able to personally relate to the topic through the process of combining concepts with their own funds of knowledge. The student data confirmed that this particular type of personally engaging process used at the beginning of the semester had overall positive effects on student confidence and speaking levels, along with showing evidence of learning. As such, a model is proposed with specific tasks and methodology that may inform English language teachers in other countries of an effective lesson and materials’ design.
Bangladeshi Politicians, the People, and Whataboutism
Authors: Islam Shahinul
Published: June 2023

Whataboutism is a logical fallacy used to discredit an opponent’s claim by deflecting it to something else. In the present world the practice of whataboutism, an old phenomenon, spreads like a disease and it is the disease that is contagious. In the present world, whataboutism sees its distinct manifestation in the speech of Donald Trump, the present American president, and many others. To cut the ground from under the feet of their opponents, some Bangladeshi politicians, like Trump, use this whataboutism without paying proper attention to the effects of it in the long course of the country which is still fighting its way to an emerging social democratic state with a steady economy. This practice in Bangladesh, like many other countries, lets the politicians go loose on many happenings which they are accused of. Consequently, the condition of good governance in Bangladesh becomes vulnerable. Bangladesh, the country which already embarked on the highway of middle-earning economy in the world, has already been decelerated for such a political standpoint. These politicians always look to blame their opponents to convince the people that whatever they have done is of almost no harm in comparison with what somebody else has done. In this article, I intend to analyze, through a case study and analytical induction, the relationship between the Bangladeshi people and politicians who deflect real facts, and the impacts of whataboutism which results in impediments in the progress towards the social democracy envisioned before and during the inception of the Liberation War of 1971.
Noh Collaboration:
Authors: Vali Abid
Published: June 2023

Ezra Pound was initially more interested in Noh than in Ernest Fenollosa’s notes on Chinese poetry. The attention paid to “Ezra Pound and China” often obscures Pound’s interest in Noh, his first love in Fenollosa’s notes, and the actual work of the collaboration/s that resulted in the published texts. Pound gained specific ideas and cultivated particular relationships due to his prior attention to Noh. In fact, given the presence of Japanese interlocutors and translators to aid Fenollosa in the creation of his notes which Ezra Pound then went on to utilize, it might be argued that the Noh plays, such as Nishikigi, that Pound published would be “closer” to the originals (given one less level of “translation”), as it were, than his efforts in Cathay, thus, more suited to his purpose of bringing disparate cultures to an understanding rooted in their common humanity
Development Sequence of Person Markers in Pre-school Children
Authors: Sanjana Lubaba
Published: June 2023

This study investigates the development sequence of person markers in pre-school children. It observed participants’ accurate use of person markers through a picturesupported elicitation task. Ten children with normal language development, aged between 2.5 and 4 years, participated in the task. Eight different verbs with three person markers for progressive aspect in present tense were elicited from participants. The mean score and standard deviation for each person marker used indicated that participants faced difficulty in producing accurate second person marker. Each participant showed highest accuracy in producing third person marker for each verb form. An implication of the study can be to determine the accuracy order of verbal inflection based on person markers in the process of Bengali language acquisition in children. It can also be helpful in cross-linguistic studies on morphological development of young children.

It also unveils his indomitable spirit for independence, his lifelong fight against tyranny and injustice, his undying love for his people, and altogether manifests Mujib as the vanguard of freedom. Thus, the book inevitably carries great significance for Bangladesh as well as for the world.
Legislative Tasks for Implementing Integrated Community Care: Focused on Administrative Affairs and Organization
Authors:   Korean Administrative Law Association, Park Jeong Yeon
Published: June 2023

The new government is implementing Integrated Community Care as a national task in the field of health and welfare, and continuing the previous government's policy, materializing and its legalization is under way. Currently, two bills are pending in the National Assembly and the Ministry of Health and Welfare is drafting another bill, but jurists are not interested in them. The purpose of this article is to approach Integrated Community Care from a legal point of view and to present in what direction the affairs and organizations related to Integrated Community Care should be legislated and reorganized. First, I clarified the background and implications of the promotion of Integrated Community Care and defined the its legal concept as the basis of legislation. In addition to enacting a basic law and reorganizing individual laws as a legislative task for Integrated Community Care, I suggested the direction of legal reform in terms of the connection of integrated care affairs, organization, finance, and administrative plans. Furthermore, as legal tasks for integration and linkage, 1) integration and linkage of medical care and care, 2) improvement of legislation for connection with housing support, and 3) Establishment of Integrated Information System and Standardization of Information were presented. Finally, as community integration care entails a change in the social security system and may cause confusion in legal aspects, it was emphasized again that the state should promote legislation through close review not only in policy but also in related legislation.
Polizeiliche Reaktion auf Veränderungen der Polizeisituation im 21. Jahrhundert
Authors:   Korean Administrative Law Association, Suh Jung-Bum
Published: June 2023

Die Polizei hat die grundlegende Aufgabe, Gefahr für das öffentliche Sicherheit und die öffentliche Ordnung abzuwehren. Seit dem 9.11 Terror hat sich die Sicherheitslage Mit der Entstehung neuer Massengefahr grundlegend verändert. Heute bemühen sich Länder auf der ganzen Welt, die Sicherheit ihrer Bürger durch die Bewältigung dieser neuen Massengefahr zu gewährleisten. In diesem Aufsatz wird der Autor die (rechtliche) Reaktion gegen diese Situationen durch unser Land diskutieren. Andererseits ist es wahr, dass eine solche Lösung nur dann sinnvoll sein kann, wenn sie in allen rechtlichen, institutionellen und sozialen Aspekten auf vielfältiger Ebene diskutiert wird. Ich möchte hier jedoch vor allem auf die Rechtslage eingehen, insbesondere auf die jüngsten Änderungen des Gesetzes.
1. Die Schwerpunkte des Polizeiaufgabebgesetzes Das “Polizeiaufgabengesetz hat die folgenden Inhalte durch die jüngsten Gesetzesänderungen festgelegt.
(1) Erweiterung des Aufgabenumfangs der Polizei Zu Aufgabenumfangs der Polizei kommen der Schutz des Lebens/Körpers und des Eigentums von Personen, die internationale Zusammenarbeit mit ausländischen Behörden und internationalen Organisationen sowie der Schutz von Opfern von Straftaten hinzu.
(2) Erfassung der Rechtsgrundlage für die Verarbeitung personenbezogener Daten durch die Polizei Die handelnrechtsliche Grundlage(Befugnisnorm) für die Erhebung und Verarbeitung personenbezogener Daten durch die Polizei wird erfasst.
(3) Erfassung der Vorschrift für Die polizeiliche Entschädigung Für Verlusten, die durch rechtsgemäße polizeiliche Maßnahmen entstanden sind, wurden Vorschriften zur Entschädigung erlassen. Insbesondere die Einrichtung der Vorschriften über die Entschädigung von immaterielle Verlusten und Entschädigung fü Nichtstörer halte ich für einen wichtigen Gesetzgebungs.
2. Hauptpunkte des ｢Gesetzes über die Organisation und den Betrieb der nationalen und autonomen Polizei｣ In unserem Land gibt es seit langem eine Reihe von Arbeiten, um die Polizeigewalt auf Staat und Provinzen zu verteilen, und als Ergebnis dieser Arbeit wurde autonome Polizei im Juli 2021 durch das “Gesetz über die Organisation und den Betrieb der nationalen Polizei und der autonomen Polizei” gestartet. In der Zwischenzeit entscheidet sich die autonome Polizei unseres Land für das sogenannte Einheitsmodell.
Inzwischen wurde im August 2002 Mit dem Inkraftsetzen der ÄAmtsordnung über Innenministerium und zugehöriges Organ“ Polizeidirektion als Unterorganisation des Innenministeriums eingerichtet. Also das Problem der demokratische Kontrolle und politische Neutralität wird gelöst.
Failed Totalitarian Art: English Military Painting of the First World War
Authors: Avdeev Vasilii Aleksandrovich
Published: June 2023

The subject of this article is subjects on the military theme in the paintings of European artists of the first half of the twentieth century.The object of the study is the stylistic and artistic features of painting by British military artists and painters of totalitarian states of the first half of the twentieth century. For the first time in domestic practice, the author offers to consider the unique phenomenon of British military painting of the First World War. She compares Italian aerofuturism, a style adopted by the fascist regime during the Second World War, which is close to her in spirit and connected with her modernist roots. The research was based on the provisions of the domestic author Igor Golomstock, who took the principle of the megamachine of the American historian and philosopher Lewis Mumford as a criterion for determining totalitarian art. The main conclusions of this study are the confirmation of the effectiveness of the Mumford formula in determining the criteria for the belonging of paintings to totalitarian art. At the same time, the considered example of English military painting, created in a democratic state, but bearing obvious features of totalitarian art, raises the question of the unambiguity of the correlation of the latter with the authoritarian form of government. The novelty of this work is the very possibility of familiarizing the domestic reader with the most interesting artistic and spiritual phenomenon - English military painting, closely related to Vorticism, the national trend of modernism, also insufficiently familiar to our public In addition, a wide range of issues related to the art history problem of identifying criteria for totalitarian art is considered
Linguistic explication of the concept of FORGIVENESS in the Avar and Russian conceptosphere
Authors: Magomedova Patimat Aripovna , Abdulatipova Bakhu Itarkuevna
Published: June 2023

This article is an analysis of the peculiarities of the linguistic embodiment of the concept of FORGIVENESS in the context of Russian and Avar linguistic cultures based on the material of religious texts and paremias. The analysis is based on a comprehensive methodological approach that includes linguistic and cultural methods of analysis. The linguistic embodiment of the concept manifests itself in a wide range of linguistic means - from words and expressions to proverbs and catch phrases. The specificity of the concept of FORGIVENESS is manifested in a parallel explication of both the reality of the religious picture of the world and the everyday one. The similarities in the representation of the conceptual signs of forgiveness in the compared languages are characteristic of the conceptual component of the concept, the differences are determined by the interpretative and meaningful spheres. The communicative situation of forgiveness is closely related to another situation of repentance, apology. The objects of the situation of forgiveness can be sin, harm, offense, debt. The concept of FORGIVENESS in both linguistic cultures has a purely positive connotation. And it is regarded as something without which life is impossible, meaningless. Forgiveness brings relief both to the one who receives forgiveness and to the one who gives forgiveness. The study showed that the concept of FORGIVENESS penetrates into all spheres of people's lives and makes them seriously think about their attitude to understanding the most important spiritual components of human life. The consideration of concrete examples of the linguistic use of these concepts in speech shows their versatility and high importance in the Russian and Avar linguistic cultures.
The Effects of Lock-down 2020 on the Behaviour and Mood of Children Aged Three to Six in Italy
Authors: Sacchi Domiziana , Pasini Augusto , Muti Marco , Roverselli Carla , Spiridigliozzi Simonetta
Published: June 2023

The aim of this research was to trace an association between the lock-down caused by the Covid-19 pandemic in Itlay (March-May 2020) and possible short- and long-term behavioral and mood changes in 1,000 children aged three to six years. With the data collected through the administration of two questionnaires, an account of the psychoattitudinal performance of the subjects examined during the aforementioned period was obtained. The results showed that during the lock-down nearly 60% of the sample exhibited negative feelings; 11.2% of the sample also exhibited symptoms attributable to situational depression. With the return to normalcy, the percentage of negative feelings recorded in the sample decreased to 11%; a significant association was also found between the mood state and temperament of the subjects. Behavioral changes such as increased onychophagy and eating changes during lock-down were recorded, which can be associated with stress. It was possible to reveal problems in the long term, such as difficulty in modulating anxiety, controlling aggression, and social adjustment.
How microscopic epistasis and clonal interference shape the fitness trajectory in a spin glass model of microbial long-term evolution
Authors: Boffi Nicholas M , Guo Yipei , Rycroft Chris H , Amir Ariel
Published: June 2023

The adaptive dynamics of evolving microbial populations takes place on a complex fitness landscape generated by epistatic interactions. The population generically consists of multiple competing strains, a phenomenon known as clonal interference. Microscopic epistasis and clonal interference are central aspects of evolution in microbes, but their combined effects on the functional form of the population’s mean fitness are poorly understood. Here, we develop a computational method that resolves the full microscopic complexity of a simulated evolving population subject to a standard serial dilution protocol. Through extensive numerical experimentation, we find that stronger microscopic epistasis gives rise to fitness trajectories with slower growth independent of the number of competing strains, which we quantify with power-law fits and understand mechanistically via a random walk model that neglects dynamical correlations between genes. We show that increasing the level of clonal interference leads to fitness trajectories with faster growth (in functional form) without microscopic epistasis, but leaves the rate of growth invariant when epistasis is sufficiently strong, indicating that the role of clonal interference depends intimately on the underlying fitness landscape.

Hunger- and thirst-sensing neurons modulate a neuroendocrine network to coordinate sugar and water ingestion
Authors: González Segarra Amanda J , Pontes Gina , Jourjine Nicholas , Del Toro Alexander , Scott Kristin
Published: June 2023

Consumption of food and water is tightly regulated by the nervous system to maintain internal nutrient homeostasis. Although generally considered independently, interactions between hunger and thirst drives are important to coordinate competing needs. In Drosophila, four neurons called the interoceptive subesophageal zone neurons (ISNs) respond to intrinsic hunger and thirst signals to oppositely regulate sucrose and water ingestion. Here, we investigate the neural circuit downstream of the ISNs to examine how ingestion is regulated based on internal needs. Utilizing the recently available fly brain connectome, we find that the ISNs synapse with a novel cell-type bilateral T-shaped neuron (BiT) that projects to neuroendocrine centers. In vivo neural manipulations revealed that BiT oppositely regulates sugar and water ingestion. Neuroendocrine cells downstream of ISNs include several peptide-releasing and peptide-sensing neurons, including insulin producing cells (IPCs), crustacean cardioactive peptide (CCAP) neurons, and CCHamide-2 receptor isoform RA (CCHa2R-RA) neurons. These neurons contribute differentially to ingestion of sugar and water, with IPCs and CCAP neurons oppositely regulating sugar and water ingestion, and CCHa2R-RA neurons modulating only water ingestion. Thus, the decision to consume sugar or water occurs via regulation of a broad peptidergic network that integrates internal signals of nutritional state to generate nutrient-specific ingestion.
What AlphaFold tells us about cohesin’s retention on and release from chromosomes
Authors: Nasmyth Kim A. , Lee Byung-Gil , Roig Maurici B. , Löwe Jan
Published: June 2023

Cohesin is a trimeric complex containing a pair of SMC proteins (Smc1 and Smc3) whose ATPase domains at the end of long coiled coils (CC) are interconnected by Scc1. During interphase, it organizes chromosomal DNA topology by extruding loops in a manner dependent on Scc1’s association with two large hook shaped proteins called SA (yeast: Scc3) and Nipbl (Scc2). The latter’s replacement by Pds5 recruits Wapl, which induces release from chromatin via a process requiring dissociation of Scc1’s N-terminal domain (NTD) from Smc3. If blocked by Esco (Eco)-mediated Smc3 acetylation, cohesin containing Pds5 merely maintains pre-existing loops, but a third fate occurs during DNA replication, when Pds5-containing cohesin associates with Sororin and forms structures that hold sister DNAs together. How Wapl induces and Sororin blocks release has hitherto remained mysterious. In the twenty years since their discovery, not a single testable hypothesis has been proposed as to their role. Here, AlphaFold 2 (AF) three-dimensional protein structure predictions lead us to propose formation of a quarternary complex between Wapl, SA, Pds5, and Scc1’s NTD, in which the latter is juxtaposed with (and subsequently sequestered by) a highly conserved cleft within Wapl’s C-terminal domain (CTD). AF also reveals how Scc1’s dissociation from Smc3 arises from a distortion of Smc3’s CC induced by engagement of SMC ATPase domains, how Esco acetyl transferases are recruited to Smc3 by Pds5, and how Sororin prevents release by binding to the Smc3/Scc1 interface. Our hypotheses explain the phenotypes of numerous existing mutations and are highly testable.

Toxicity Assessment of Produced Water Using Nitrosomonas sp.
Authors: Tudararo-Aherobo L. E. , Egieya A. J.
Published: June 2023

Aim: Most studies on the effect of produced water are centred on the effects on the physicochemical parameters of the recipient environment, but not much has been conducted on biogeochemical processes such as the nitrogen cycle. This study aims to determine the median lethal concentration (LC50) of the produced water that would cause mortality of 50% of the exposed population of Nitrosomonas sp. (test organism) which is involved in the ammonification step of the Nitrogen cycle.

Study Design:  For the purpose of this study, acute toxicity testing was done for 48 hours to determine the effect of the untreated and treated produced wastewater on the test organism. The LC50 is the median lethal concentration that would cause mortality of 50% of the exposed population of the test organisms.

Methodology: Toxicity effects of treated and untreated produced wastewater were determined following standard procedures against the test organism (Nitrosomonas sp). The resultant output of the probit analysis was generated from the SPSS statistical programme.

Results: Results showed that the mean LC50 for the untreated produced wastewater at the 48-hour test period of bioassay was 3.27mg/L, while the mean LC50 for the treated wastewater was found to be 6.69mg/L. The mean percentage mortality of Nitrosomonas sp. for the untreated produced waster water ranged from 37%(0.01mg/l) to 90%(100mg/l), while for the treated, percentage mortality ranged from 27%(0.01mg/l) to 84%(100mg/l) at the end of the 48 hour test duration.

Conclusion: Toxicity of treated and untreated wastewater against Nitrosomonas sp increased with time and decreased considerably with treatment, corresponding to positive correlation as observed statistically between toxicants with respect to concentration and time of exposure for untreated and treated wastewater against Nitrosomonas sp. These results indicate a likey inteference of the nitrogen cycle by contamination of untreated produced water in the environment and by extension impairment of the productivity of the environment.
Machine Learning Approach for House Price Prediction
Authors: Chowhaan M. Jagan , Nitish D. , Akash G. , Sreevidya Nelli , Shaik Subhani
Published: June 2023

In our ecosystem, real estate is clearly a distinct industry. Predicting house prices, significant housing characteristics, and many other things is made a lot easier by the capacity to extract data from raw data and extract essential information. Daily fluctuations in housing costs are still present, and they occasionally rise without regard to calculations. According to research, changes in property prices frequently have an impact on both homeowners and the real estate market.

To analyze the key elements and the best predictive models for home prices, literature research is conducted. The analyses' findings supported the usage of artificial neural networks, support vector regression, and linear regression as the most effective modeling techniques. Our results also imply that real estate agents and geography play important roles in determining property prices. Finding the most crucial factors affecting housing prices and identifying the best machine learning model to utilize for this research would both be greatly aided by this study, especially for housing developers and researchers.

Published: June 2023

Three separate field experiments were carried out at the Agricultural College and Research Institute, TNAU, Madurai, India during 2019-22 with the aim of assessing the possibility of achieving soil organic carbon principle '4p1000' a recent initiative in restoring soil health, through a novel farming system of Low Budget Naturalway Farming by cultivating millets and pulse crops,. The experiments focused on monocropping of millets, sequential multiple cropping and intercropping of millets, and pulses. The studies continuously assessed soil organic carbon status of the cultivated fields to see whether 4p1000 is feasible under tropical conditions. The results of the trials revealed that, despite the LBNF practice of using tree leaf biomass as a source of nutrients, monocropping failed to realize the principle. However, it was feasible to accomplish this when a millet-pulse system was employed and a black gram pulse crop was introduced to the system. The intercropping of pulses and millets would contribute further to the accumulation of soil organic carbon in the cultivated fields. The study proved that the 4p1000 principle is achievable in the tropics.

Published: June 2023

As technology improved, object detection, which is connected to video and image analysis, caught researchers' interest. Earlier object recognition techniques are based on hand-crafted features and imprecise architectures and trainable algorithms. One of the main issues with many object detection systems is that they rely on other computer vision methods to support their deep learning-based methodology, which leads to slow and subpar performance. In this article, we present an end-to-end solution to the object detection problem using a deep learning based method. The single shot detector (SSD) technique is the quickest method for object detection from an image using a single layer of a convolution network. Our research's primary goal is to enhance accuracy of SSD method.

Published: June 2023

As the promising next‐generation energy storage solution, lithium metal battery (LMB) has gained great attention but still suffers from troubles associated with the highly active metallic lithium. Herein, it is aimed to develop an anode‐free LMB engaging no Li disk or foil by modifying the Cu current collector with mercapto metal–organic frameworks (MOFs) impregnating Ag nanoparticles (NPs). While the polar mercapto groups facilitate and guide Li+ transport, the highly lithiophilic Ag NPs help to enhance the electric conductivity and lower the energy barrier of Li nucleation. Furthermore, the MOF pores allow compartmentalizing bulk Li into a 3D matrix Li storage so that not only the local current density is reduced, but also is the plating/stripping reversibility greatly enhanced. As a result, full cells pairing the prelithiated Ag@Zr‐DMBD/Cu anodes with LiFePO4 cathodes demonstrate a high initial specific capacity of 159.8 mAh g−1, first‐cycle Coulombic efficiency of 96.6%, and long‐term cycling stability over 1000 cycles with 99.3% capacity retention at 1 C. This study underlines the multi‐aspect functionalization of MOFs to impart lithiophilicity, polarity, and porosity to achieve reversible Li plating/stripping and paves the way for realizing high‐performance anode‐free LMBs through exquisite modification of the Cu current collector.
Circularly Polarized Luminescence Switching, Chirality Self‐Sorting, and Cell Imaging of Chiral Rhodamine Dyes

Published: June 2023

Rhodamine dyes, as star molecules of fluorescent dyes, are critical tools in modern analytical and biochemical research. However, switching their chiroptical properties still remains a big challenge because of the absence of a suitable synthesis method to incorporate through conjugation a chiral fragment into the chromophore core of rhodamine. Herein, a simple and straightforward way is utilized to link two rhodamine chromophores by different chiral bridges. The conjugated RRR/SSS birhodamine dyes with one axial chirality, which is constructed directly by two rhodamine chromophores, and two spirocyclic chiralities show the interesting circular dichroism and circularly polarized luminescence switching and lysosome‐targetable properties. On the other hand, the unconjugated RR/SS birhodamine dyes with two chiral carbons do not have such chiroptical switching properties but do have different amazing cellular staining properties. The RR birhodamine dye can stain both lysosomes and mitochondria, but SS birhodamine dye can stain lysosomes only. Moreover, the mechanisms of chiroptical switching and diastereoselectivity are investigated as well, based on single‐crystal structures and density functional theory calculations. Therefore, a new platform is afforded here in designing chiral dyes for chiroptical switching and cell imaging applications.

We report a photocatalytic strategy for selective reduction of nitroarenes to azoxy‐, azo‐ and hydrazo‐compounds catalyzed by bismuth porphyrin metal organic framework (Bi‐MOF) through controlling time, atmosphere, or the quantity of NaBH4 under mild conditions (Rt, Light). The photocatalytic protocol exhibited excellent functional group compatibility, and the recyclability of Bi‐MOF was demonstrated by five cycle tests. More importantly, the scale‐up experiment of 10 g can also be carried out smoothly with excellent yield of 95%. This green and effective photocatalytic strategy provides a practical possibility for the large‐scale synthesis of azo intermediates.

A synthetic method to prepare 1,2‐diamines efficiently that relies on the 4CzPN‐catalysed α‐aminoalkylation of azomethine imines by secondary and tertiary α‐silylamines under blue light emitting diode (LED) light (456 nm) is described. Achieved under metal‐ and additive‐free reaction conditions at room temperature, the synthetic protocol was shown to afford product yields up to 99% and applicable to the late‐stage functionalisation of three drug molecules and the gramme‐scale preparation of one example.

Integrated circuits (ICs) are challenged to deliver historically anticipated performance improvements while increasing the cost and complexity of the technology with each generation. Front‐end‐of‐line (FEOL) processes have provided various solutions to this predicament, whereas the back‐end‐of‐line (BEOL) processes have taken a step back. With continuous IC scaling, the speed of the entire chip has reached a point where its performance is determined by the performance of the interconnect that bridges billions of transistors and other devices. Consequently, the demand for advanced interconnect metallization rises again, and various aspects must be considered. This review explores the quest for new materials for successfully routing nanoscale interconnects. The challenges in the interconnect structures as physical dimensions shrink are first explored. Then, various problem‐solving options are considered based on the properties of materials. New materials are also introduced for barriers, such as 2D materials, self‐assembled molecular layers, high‐entropy alloys, and conductors, such as Co and Ru, intermetallic compounds, and MAX phases. The comprehensive discussion of each material includes state‐of‐the‐art studies ranging from the characteristics of materials by theoretical calculation to process applications to the current interconnect structures. This review intends to provide a materials‐based implementation strategy to bridge the gap between academia and industry.

The treatment of myocardial infarction (MI) remains a substantial challenge due to excessive inflammation, massive cell death, and restricted regenerative potential, leading to maladaptive healing process and eventually heart failure. Current strategies of regulating inflammation or improving cardiac tissue regeneration have limited success. Herein, a hybrid hydrogel coassembled by acellular cardiac extracellular matrix (ECM) and immunomodulatory glycopeptide is developed for endogenous tissue regeneration after MI. The hydrogel constructs a niche recapitulating the architecture of native ECM for attracting host cell homing, controlling macrophage differentiation via glycopeptide unit, and promoting endotheliocyte proliferation by enhancing the macrophage‐endotheliocyte crosstalk, which coordinate the innate healing mechanism for cardiac tissue regeneration. In a rodent MI model, the hybrid hydrogel successfully orchestrates a proreparative response indicated by enhanced M2 macrophage polarization, increased angiogenesis, and improved cardiomyocyte survival, which alleviates infarct size, improves wall thicknesses, and enhances cardiac contractility. Furthermore, the safety and effectiveness of the hydrogel are demonstrated in a porcine MI model, wherein proteomics verifies the regulation of immune response, proangiogenesis, and accelerated healing process. Collectively, the injectable composite hydrogel serving as an immunomodulatory niche for promoting cell homing and proliferation, inflammation modulation, tissue remodeling, and function restoration provides an effective strategy for endogenous cardiac repair.

The tribovoltaic effect is the direct‐current (DC) output that results from sliding a p‐type semiconductor on top of an n‐type semiconductor, and it is caused by the electron–hole pairs generated However, the rigid structure of traditional semiconductor limits its potential application in wearable fields. Here, p–type and n–type fabric with semiconductor properties are prepared by doping small organic molecules of cetyltrimethylammonium bromide and sodium dodecylbenzene sulfonate on the carbon atoms of single–wall carbon nanotubes (SWCNTs), and three all‐fabric direct‐current triboelectric nanogenerators based on the tribovoltaic effect (AFDC‐TENG) are developed , which exhibit high flexibility, satisfactory comfort, and stable DC output. In addition, the effects of structural parameters and environmental factors on the electrical output of AFDC‐TENG are systematically discussed. The output voltage, current, and power density of p‐type AFDC‐TENG can reach 0.2 V, 0.29 µA, and 45.5 mV m−2 at a maximum speed of 0.2 m s−1 and a sliding frequency of 1 Hz, respectively. This work proposes a simple and scalable design form for all‐fabric DC power supply devices, which has potential applications in the future micro/nano energy or self‐powered flexible sensors.

Asymmetric cross‐couplings based on 1,2‐carbon migration from B‐ate complexes have been developed efficiently to access valuable organoboronates. However, enantioselective reactions triggered by 1,2‐boron shift have remained to be unaddressed synthetic challenge. Here, Ir‐catalyzed asymmetric allylic alkylation enabled by 1,2‐boron shift was developed. In this reaction, we disclosed that excellent enantioselectivities were achieved through an interesting dynamic kinetic resolution (DKR) process of allylic carbonates at the elevated temperature. Notably, the highly valuable (bis‐boryl)alkenes have enabled an array of diversifications to access versatile molecules. Extensive experimental and computational studies were conducted to elucidate the reaction mechanism of DKR process and clarify the origin of excellent enantioselectivities.

The 3D hybrid framework [{Cu(cyclam)}3(κ‐Mo8O27)] ⋅ 14H2O (1) (cyclam=1,4,8,11‐tetraazacyclotetradecane) undergoes sequential single‐crystal‐to‐single‐crystal transformations upon heating to afford two different anhydrous phases (2 a and 3 a). These transitions modify the framework dimensionality and enable the isomerization of κ‐octamolybdate (κ‐Mo8) anions into λ (2 a) and μ (3 a) forms through metal migration. Hydration of 3 a involves condensation of one water molecule to the cluster to afford the γ‐Mo8 isomer in 4, which dehydrates back into 3 a through the 6 a intermediate. In contrast, 2 a reversibly hydrates to form 5, exhibiting the same Mo8 cluster as that of 1. It is remarkable that three of the Mo8 clusters (κ, λ and μ) are new and that up to three different microporous phases can be isolated from 1 (2 a, 3 a, and 6 a). Water vapor sorption analyses show high recyclability and the highest uptake values for POM‐based systems. The isotherms display an abrupt step at low humidity level desirable for humidity control devices or water harvesting in drylands.
