Tetracene Dimers: A Platform for Intramolecular Down- and Up-conversion
Authors: Guldi Dirk , Bo Yifan , Hou Yuxuan , Thiel Dominik , Weiss Rene , Clark Tim , Ferguson Michael , Tykwinski Rik
Published: May 2023

Photon energy conversion can be accomplished in many different ways, including the two opposing manners, down-conversion (i.e., singlet fission, SF) and up-conversion (i.e., triplet-triplet annihilation up-conversion, TTA-UC). Both processes have the potential to help overcome the detailed balance limit of single-junction solar cells. Tetracene, in which the energies of the lowest singlet excited state and twice the triplet excited state are comparable, exhibits both down- and up-conversion. Here, we have designed meta-diethynylphenylene- and 1,3-diethynyladamantyl-linked tetracene dimers, which feature different electronic coupling, to characterize the interplay between intramolecular SF (intra-SF) and intramolecular TTA-UC (intra-TTA-UC) via steady-state and time-resolved absorption and fluorescence spectroscopy. Furthermore, we have used Pd-phthalocyanine as a sensitizer to enable intra-TTA-UC in the two dimers via indirect photoexcitation in the near-infrared part of the solar spectrum. The work is rounded off by temperature-dependent measurements, which outline key aspects of how thermal effects impact intra-SF and intra-TTA-UC in the different dimers.

Published: May 2023

The potential of phosphites as nucleophiles for the synthesis of chiral chromene derivatives has been overlooked in the literature. Herein, we report a highly promising approach via asymmetric organocatalyzed phospha-Michael addition to iminochromenes, using a bifunctional squaramide. Our optimized protocol provides very good reactivity, affording yields of up to 95% and excellent enantioselectivity, with chiral products exhibiting an outstanding enantiomeric excess of up to 98%.

Published: May 2023

A new series of compounds planned by molecular hybridization of the nucleobases uracil and thymine, or the xanthine theobromine, with coumarins, and linked through 1,2,3-triazole heterocycles were evaluated for their in vitro anticancer activity against the human tumor cell lines: colon carcinoma (HCT116), laryngeal tumor cells (Hep-2), and lung carcinoma cells (A549). The hybrid compound 7a exhibited better activity in the series, showing an IC50 of 24.19 ± 1.39 μM against the HCT116 cells, with a selectivity index (SI) of 6, when compared to the cytotoxicity against the non-tumor cell line HaCat. Molecular docking studies were performed on all active compounds and suggested that the synthesized compounds possess a high affinity to DNA Topoisomerase-1 protein, supporting their antitumor activity. The in silico toxicity prediction studies suggest that the compounds present a low risk of causing theoretical mutagenic and tumorigenic effects. These findings indicate that the molecular hybridization from natural derivative molecules is an interesting approach to seek new antitumor candidates.
Machine learning accelerated photodynamics simulations
Authors: Li Jingbai , Lopez Steven
Published: May 2023

Machine learning (ML) continues to revolutionize computational chemistry by accelerating predictions and simulations by training on experimental or accurate but expensive quantum chemical (QC) calculations. Photodynamics simulations require hundreds of trajectories coupled with multiconfigurational QC calculations of energies, forces, and non-adiabatic couplings that contribute to the prohibitive computational cost at long timescales and complex organic molecules. ML accelerates photodynamics simulations by combining nonadiabatic photodynamics simulations with an ML model trained with high-fidelity QC calculations of energies, forces, and non-adiabatic couplings. This approach has provided time-dependent molecular structural information for understanding photochemical reaction mechanisms of organic reactions in vacuum and complex environments (i.e., explicit solvation). This review focuses on the fundamentals of QC calculations and machine learning techniques. We then discuss the strategies to balance adequate training data and the computational cost of generating these training data. Finally, we demonstrate the power of applying these ML-photodynamics simulations to understand the origin of reactivities and selectivities of organic photochemical reactions, such as cis-trans isomerization, [2+2]-cycloaddition, 4π-electrostatic ring-closing, and hydrogen roaming mechanism.
A Study on the Perception of the Crime Prevention Officer(CPO) in CPTED Projects: Focusing on the CPOs of Seoul Metropolitan Police
Authors:   KOREA CPTED ASSOCIATION, Jeong Ji Yeon , Oh Jee Hyun , Kwon Ye Jin , Park Hyeonho
Published: May 2023

There has been growing anxiety that anyone can be a victim of crime in various places, and related administrative agencies are proposing new policy in line with the civil society’s demand for crime prevention. On June 1, 2016, the National Police Agency organized a Crime Prevention Officer (CPO) at 140 nationwide priority(1급지) police stations and disclosed its active will to perform full-scale crime prevention tasks. The definition of the CPO is police officer who performs functions such as diagnosing, analyzing the crime environment and crime occurrence factors in Si/Gun/Gu or Eup/Myeon/Dong level, strengthening cooperation with other institutions and residents, and strengthening the promotion of commission activities and crime prevention activities for victims of crime. At present, CPO works in the field by applying the CPTED strategy, such as analyzing crime hot spots, diagnosing risk factors, and installing necessary crime prevention facilities which can be said to mean CPTED personnel. In this study, in order to research the perception of CPO’s that have an important role in the CPTED project, a survey was conducted on CPO’s in Seoul Metropolitan Police Safety Division. As a result of the study analysis, the question of the need for systematic education of CPO was most positive, and the most important parts of CPO professional education were sharing the actual case and crime prevention/CPTED theory education by an expert. In addition, it was confirmed that the more people think that the CPTED project affects the trust of the police, the more positive they are aware of the core elements of the CPTED project, the effectiveness of target hardening, and the need for education of CPO. Based on these findings, the above study presented and emphasized the future development plan of CPO and the importance of CPTED projects by confirming the effectiveness and key elements of CPTED projects and the importance of CPO. This is meaningful as basic data for CPO's perception survey, and additional research and support should be continued so that CPO can do its role as an expert responsible for the people's safety of life.

Published: May 2023

Many viruses require proteolytic activation of their envelope proteins for infectivity, and relevant host proteases provide promising drug targets. The transmembrane serine protease 2 (TMPRSS2) has been identified as a major activating protease of influenza A virus (IAV) and various coronaviruses (CoV). Increased TMPRSS2 expression has been associated with a higher risk of severe influenza infection and enhanced susceptibility to SARS-CoV-2. Here, we found thatLegionella pneumophilastimulates the increased expression of TMPRSS2-mRNA in Calu-3 human airway cells. We identified flagellin as the dominant structural component inducing TMPRSS2 expression. The flagellin-induced increase was not observed at this magnitude for other virus-activating host proteases. TMPRSS2-mRNA expression was also significantly increased by LPS, Pam3Cys, andStreptococcus pneumoniae, although less pronounced. Multicycle replication of H1N1pdm and H3N2 IAV but not SARS-CoV-2 and SARS-CoV was enhanced by flagellin treatment. Our data suggest that bacteria, particularly flagellated bacteria, up-regulate the expression of TMPRSS2 in human airway cells and, thereby, may support enhanced activation and replication of IAV upon co-infections. In addition, our data indicate a physiological role of TMPRSS2 in antimicrobial host response.
The CHARGE syndrome-associated protein FAM172A controls AGO2 nuclear import

Published: May 2023

CHARGE syndrome is a neural crest-related disorder mainly caused by mutation of the chromatin remodeler-coding geneCHD7. Alternative causes include mutation of other chromatin and/or splicing factors. One of these additional players is the poorly characterized FAM172A, which we previously found in a complex with CHD7 and the small RNA-binding protein AGO2 at the chromatin–spliceosome interface. Focusing on the FAM172A–AGO2 interplay, we now report that FAM172A is a direct binding partner of AGO2 and, as such, one of the long sought-after regulators of AGO2 nuclear import. We show that this FAM172A function mainly relies on its classical bipartite nuclear localization signal and associated canonical importin-α/β pathway, being enhanced by CK2-induced phosphorylation and abrogated by a CHARGE syndrome-associated missense mutation. Overall, this study thus strengthens the notion that noncanonical nuclear functions of AGO2 and associated regulatory mechanisms might be clinically relevant.

Published: May 2023

O artigo é resultado de pesquisa do mestrado que objetivou analisar a percepção dos professores de educação física sobre formação continuada, explorando as tensões que se estabelecem entre as ações desenvolvidas, as expectativas dos professores e as possibilidades para qualificar a sua prática pedagógica a partir da participação em processos formativos. Trata-se de uma pesquisa descritiva, com uma abordagem qualitativa que utilizou a entrevista semiestruturada para coletas de dados. Para a análise e interpretação dos dados, utilizamos a análise temática, revelando que os processos de formação continuada apresentam fragilidades em relação às ações desenvolvidas ao distanciar-se de questões didático-metodológicas especificas da educação física escolar, divergindo, assim, quanto às intencionalidades e objetivos. Identificou-se a convergência sobre a necessidade de considerar os desafios e dificuldades que emergem da docência no campo da educação física escolar como ponto de partida para pensar os processos formativos, constituindo-se em espaço de reflexão e ressignificação de sua prática pedagógica, contemplando, ainda, a reflexão sobre as especificidades e particularidades deste componente curricular.
Egressos do Pibid: o movimento de aprender a ser professor e o fazer docente em sala de aula
Authors: Nakade Jéssica Pereira de Oliveira , Paniago Rosenilde Nogueira
Published: May 2023

Este artigo tem como objeto de estudo, o saber e o fazer docente dos egressos do Programa de Iniciação à Docência (Pibid). O Pibid trata-se de uma política pública educacional criada para contribuir com a formação de professores e incentivar a atuação na docência, principalmente, na educação básica. A pesquisa foi realizada a partir da seguinte questão: quais as contribuições do Pibid para a aprendizagem docente de egressos? O objetivo foi identificar as contribuições do Pibid para o saber e o fazer docente de egressos. Utilizou-se da investigação narrativa, cujo instrumento principal foi constituído por narrativas orais de formação com cinco professores egressos do Pibid. Os resultados sinalizam que o Pibid é um programa que incita práticas inovadoras de aproximação da IES com a escola e oportunizou aos egressos aprendizagens de vários saberes que estão mobilizando como professores que vão desde o planejamento, a forma de lidar com os alunos, a problematização do papel do ensino ao uso de diversos métodos de ensino. Contudo, considera-se ser o Pibid um programa frágil pois, é condicionado a disponibilidades orçamentárias e não contempla todos os licenciandos dos cursos de formação inicial de professores e não inclui também todas as áreas disciplinares das Licenciaturas.

Authors: França Carlos Eduardo , Barros Rodolfo Arruda Leite de , Castro Patrícia Cardoso Medeiros de
Published: May 2023

A proposta deste artigo é analisar o papel das Unidades Educacionais de Internação do Mato Grosso do Sul (UNEI - MS) enquanto dispositivo que exerce poder de controle social da juventude autora de atos infracionais, especificamente adolescentes submetidos às medidas socioeducativas de internação. O objetivo foi analisar as influências dos dispositivos legais, associados às instituições estatais de controle, em um contexto de avanço do Estado penal, que promoveram a centralidade da figura do “delinquente” sentenciado, majoritariamente, pelos crimes de roubo e tráfico de drogas, intensificado por influências da lei 11.343/2006. Essas mudanças reforçaram discursos institucionais que constroem a figura do “delinquente” sentenciado pela ilegalidade do tráfico de drogas, intensificando a criminalização da juventude e a punitividade no sistema socioeducativo. Utilizamos pesquisas bibliográficas e de dados quantitativos para traçar o perfil dos adolescentes autores de atos infracionais; assim, evidenciamos como os dados gerais do sistema de justiça criminal, quando observados a partir de recortes como raça, gênero, classe social, escolaridade e faixa etária podem apontar para a profunda seletividade da atuação desses mecanismos institucionais disciplinares das medidas socioeducativas, que confluem para um horizonte da biopolítica ligada à justiça criminal, intensificada diante deste contingente populacional com características peculiares.

For each finite group $G$ we associate a simple undirected graph $O D(G)$, order divisor graph. We investigate the interconnection between the group theoretic properties of $G$ and the graph theoretic properties of order divisor graph $O D(G)$. For a finite group $G$, we obtain the density, the girth and the diameter of $O D(G)$. Further, we obtain the relation $G \cong G^{\prime}$ if and only if $O D(G) \cong O D\left(G^{\prime}\right)$, for every distinct finite groups $G$ and $G^{\prime}$, and $A u t o(G) \subseteq A u t o(O D(G))$.

The excessive usage of fossil fuels in Malaysia is increasing yearly to meet the increasing domestic demands. However, this will impact the environment as fossil fuels will emit hazardous gases into the atmosphere. The development of marine energy in Malaysia is still in early periods compared with China, the U.K, and America. Notably, the impact of marine energy extraction on shallow water regions is not yet fully understood, such as the changes in the topography, the effect on marine life, and the cost of development and maintenance for tidal stream energy. This paper is focused on the social and ecological impact of potential marine energy development in Malaysia. Significantly, this study relies on published data to analyse and identify potential sites for harnessing tidal stream energy. Numerical calculation shows that the coastal region receives higher available energy compared to the deep sea. Three sites are found to be the best location for tidal energy exploration in Malaysia, namely Pangkor Island, Port Klang, and the Malacca coastline. From these three sites, the available energy per year for Pangkor Island is 193.668 MWh, while for Port Klang and Malacca coastline are at 241.66 MWh, and 433 MWh respectively. Apart from the economical aspect, the social aspect of tidal energy exploration is also examined. The purpose of the Renewable Energy Act 2011 and Electricity Supply Act 1990 is to ensure proper legislation for the implementation of marine renewable energy in Malaysia, specifically regarding zones of the ocean, licensing, and installation requirements.

Geographical location of Malaysia is endowed with natural resources such as coal and fossil fuels. Unfortunately, these natural resources will run out shortly if the Malaysian government does not take appropriate measures to conserve them. To ensure that the area has enough energy and sources, a system of utilizing and introducing renewable energy such as solar, rainwater, wave and tidal current energy is established. Vertical axis tidal turbine (VATT) for shallow water applications is the main topic of this study where computational fluid dynamics (CFD) via Large-eddy simulation (LES) and Reynolds-averaged Navier-Stokes (RANS) simulation was performed in investigating the influence of the array interaction of tidal turbines. The VATT is the most suitable tidal turbine in Malaysia because the depth of the water in Malaysia ranges between 20m and 30m. In addition, the hypothetical actuator disk as a representation of the tidal turbine devices, with different turbulence models for simulating tidal turbine wakes interaction was performed. The tested turbulence models include the k-epsilon, Large Eddy Simulation (LES) and Smagorinsky-Lilly. The evaluation was done by comparing the wake generation between LES and RANS simulations’ results against the set of published experimental data regarding various arrays for the tidal turbines. The discussion involves three main parts: (i) pre-processing which concentrates on creating the model and setup parameters, (ii) processing which concentrates on visualizing the simulation data and lastly (iii) post-processing which concentrates on defining the results obtained from the ANSYS software.

Malaysia highly depends on non-renewable energy sources like fossil fuels to supply the country's growing energy needs. On the other side, the oil and gas industry is facing challenges due to the depletion of fossil fuel supplies. Renewable energy is an alternative to fossil fuels that has been developed as a means of maintaining steady development in Malaysia. This is due to the slow average current speed in the sea around the country. Various renewable energy sources have been researched, with tidal energy garnering the most interest. This study focuses on tidal turbine array configuration for shallow water applications by using a Savonius turbine. The turbine layout is challenging to deploy the tidal array properly, and the wake interaction between the devices must be studied. The multi-row and single-row arrays have been studied using Computational Fluid Dynamics (CFD) simulations. The numerical research using a CFD technique is used to explore the effect of turbine spacing and capacity on the array's wake production. The vertical axis turbine is represented by a hypothetical 'actuator' cylinder and a 'Savonius' disc (VATT). Following the domain configuration, the turbine has been configured to static modes. According to the findings, the VATT model has a faster wake recovery and follows the definition of the distant wake. When working in shallow water, staggered arrays with bigger spacing are recommended since there is a lower chance of wake mixing between the rows.

Prior studies mostly focused on physical factors such as physical fitness, motor abilities, and anthropometry as indicators for talent identification (TID). However, there are two critical issues that have been emerging recently among young athletes, which are burn-out and early drop-out. Thus, this study suggests to include another factor as an indicator for TID, which are psychological factors. The aim of this paper was to identify the psychological factors that would be good indicators for the TID programme along with the physical factors. This systematic review uses the PRISMA method to logically summarise the identified psychological and physical factors that would be good indicators for TID. A comprehensive electronic literature search was conducted via Google Scholar and open access journals. 30 literature selections were selected based on a few criteria. This systematic review conclude that a set of physical fitness, anthropometry, motor abilities and several psychological factors such as personality traits, emotional intelligence and grit should be included as TID indicators to select a physically talented athlete that have the psychological ability to endure the development process. A selected athlete might be physically competent but psychologically incompetent. This is the explanation of the importance of psychological factors must be included as indicators for the talent identification process in sports to avoid the current critical issues which are burn-out and early drop out among young talented athletes. However, a proper selection of psychological factors must be made to choose a good psychological indicator because an indicator for talent identification must be consistent throughout the time period. A longitudinal research method is required to provide more evidence for this theory.

The World Health Organization (WHO) named anti-vaxxers as one of the top ten public health hazards in 2019. Anti-vaxxers are a health danger since they are mostly responsible for the reemergence of deadly contagious diseases such as measles and diphteria, that has increased by recent years. The media, as the primary source of information, are responsible for disseminating messages and public knowledge about health issues, particularly health hazards. Despite the WHO's warning, the Malaysian media paid scant attention to anti-vaxxers. As a result, this paper proposes that newspapers, as the primary source of information, should provide critical information such as scientific and credible data to challenge anti-vaccine views online, especially by appropriately framing anti-vaxxers. This study examined the Malaysian media through a quantitative content analysis of four newspapers (Harian Metro, Berita Harian, New Straits Times, and The Star) published between 1 January 2019 and 30 September 2021. The 43-month period offered adequate data for analysing reporting trends. The findings suggested that, despite the media's sensationalization of anti-vaxxers, the media continue to fall short of educating the public on the scientific facts opposing anti-vaxxers.

Constructing a long-term mechanism to solve the relative poverty in ethnic areas is inseparable from the improvement in the self-development ability of the government in ethnic regions. The empirical analysis of the eight ethnic provinces in China showed that the self-development capabilities of the governments in ethnic regions were relatively weak; the gap between the economic regulation and public service capabilities of the provincial governments had narrowed, while the gap between social security and environmental protection capabilities had expanded. The self-development capacity of the government in ethnic areas had room for improvement. It was an important national strategy to help minority areas cultivate and improve the government's self-development capability. We observed that the differentiated policies of the state to support the improvement of the government's self-development ability in ethnic areas mainly include a fiscal transfer payment policy and mutual interest cooperation policy. Measures should be taken to improve them respectively to enhance the self-development ability of the government in ethnic areas and build a solid foundation for the construction of the Chinese nation while promoting the sustainable development of ethnic regions.

In international political realist theory, hegemonic power emergence is the inevitable result of the self-help principle derived from anarchy. Therefore, this paper analyzes the rise and fall of power in different periods of history based on academic theories such as long cycle theory, power transition theory, and hegemonic stability theory, and concludes that restraint is the basic strategic self-awareness for each competing subject to avoid the premature outbreak of structural conflicts and ensure the peaceful and stable development of the country.

Foreign athletes are a common phenomenon in all kinds of leagues around the world. It not only contributes effectively to the improvement in performance but also leads to an active football market. But in the Chinese soccer league, a low-level soccer league, how to utilize these international super players to improve the skills and tactics of local players is significant to change the current situation in the Chinese soccer environment. This research could be conducted through observation, SWOT analysis, and literature review methods to analyze how international players drive the development of local players and improve the development of Chinese soccer. The result shows that to improve the youth football training system, the CFA should make thorough policies or rules, expand the number of teams, improve the management system of football agents and clubs should establish a sound system for the management and introduction of foreign players.

This study examines the methods implemented by Islamic Education Teachers (IET) in Kinta Perak's Northern District of Malaysia on teaching Ibadah (worship). This study also looks for differences in Ibadah teaching approaches based on gender and teaching experience. This study employs a survey method along with a quantitative approach. This study used a questionnaire to determine the ibadah teaching methodology. For this study, 100 sample IETs were chosen as the respondents. The data were analysed using descriptive statistics, independent samples t-tests, and one-way ANOVA. The study provides a mean score of 4.70 and a standard deviation of 0.34 for the whole data about the teachers' method of teaching ibadah, and the interpretation is high. The highest item in this construct item is “Reprimand pupils for their inaccurate prayer behavior,” with a mean of 4.86 (S.D. = 0.37). The independent sample t-test shows no significant differences in teachers’ methods in teaching ibadah based on gender. One-way ANOVA test shows no significant difference in teachers' methods in teaching Ibadah based on teaching experiences. As a result, ongoing efforts must be made to enhance teachers' abilities and student Ibadah practice. This study significantly strengthens the ibadah-related teaching strategies used by teachers.
Atmospheric Interpolation: Between Film & Architecture
Authors:   , Huskinson-Young Max
Published: May 2023

Throughout its history architecture has long been influenced by other disciplines. As an art, architecture primarily operates between the realm of the artist and the engineer, between the aesthetic and the practical. However, there are many similarities between architecture and a range of other fields from social sciences, to history & culture, as well as sub sections of engineering and visual art such as physics, mathematics, painting and design to name a few. A multi-disciplinary consideration of architectural thinking can help progress and understand more about architecture itself. This thesis explores this premise by investigating the relationship between architecture and cinema.

Cinema and architecture share a multitude of similarities. Specifically, they both share a fundamental correlation with space and time. However, the most important aspect of this inter-disciplinary relationship is their shared connection with our emotions. Film has aunique ability to resonate with our emotional sensibility, which offers an application to architectural design through an understanding of atmosphere.

Through an iterative design-led research, this thesis examines the atmospheric interpolation between film and architecture, through a speculative investigation of the disciplines. This research is broken up into six design phases, each varying in architectural complexity and scale, My initial design stages seek to understand cinemas possible application to architecture, by employing speculative methods of drawing and architectural modelling as tools to analyse and represent identified filmic qualities. These qualities are then explored in later phases through abstract architectural interventions, with the final stage encapsulating the findings of my design research through the design of a public scale building.

This thesis does not seek to address any problem or deliberate on any practical topic of the architectural discourse, but instead explore the idea that by looking outside of our world, we may learn something about our own.
