The source origins are Greek, Roman, and Oscan religious inscriptions and literary texts. In the article, the chosen italic sanctuaries were discussed in terms of changes in their activity under the Roman influence. It also discussed the changes of certain cult forms as exemplified by Ceres and Venus. The peculiarity of attention was paid to the specific religious life in the Greek cities and their own cult offices.
Działalność dyplomatyczna Tomasza Mogilnickiego na rzecz kanclerzyny litewskiej Anny Katarzyny z Sanguszków Radziwiłłowej w latach 1730–1737
Authors: Penkała-Jastrzębska Anna
Published: July 2023

Artykuł poświęcony jest analizie aktywności Tomasza Mogilnickiego, człowieka zaufanego, przez lata zatrudnionego na usługach dworu Radziwiłłów. Mogilnicki był jednym z najbardziej zaufanych ludzi kanclerzyny wielkiej litewskiej Anny Katarzyny z Sanguszków Radziwiłłowej i jej głównym reprezentantem do prowadzenia interesów zagranicznych. W analizowanym okresie spraw newralgicznych, w które zaangażowany został Mogilnicki było przynajmniej kilka – począwszy działania w interesie spornych spraw majątkowych – fundamentalnych dla Anny Katarzyny z Sanguszków Radziwiłłowej –– poprzez trudny pod względem politycznym i dyplomatycznym okres wolnej elekcji po śmierci Augusta II, aż po agitowanie w kręgu dworskim na rzecz synów kanclerzyny, podobnie jak poszukiwanie dróg do uzyskania królewskiej łaski względem dystrybucji królewszczyzn i starostw na rzecz krewnych i koligatów Radziwiłłowej. Jedną z najważniejszych spraw było jednak prowadzanie negocjacji na dworze w Mannheim w sprawie małżeństwa Hieronima Floriana Radziwiłła z Marią Franciszką Dorotą von Sulzbach, wnuczką Elektora Karola III Filipa Wittelsbacha. Zachowana korespondencja pozwala nie tylko na bliższe przyjrzenie się aktywności samego Mogilnickiego, ale też na analizę założeń polityki małżeńskiej i finansowej Radziwiłłów w pierwszej połowie XVIII wieku.
The Polish-Soviet War in the Norwegian Press of the Years 1920-1921
Authors: Siemianowski Jordan
Published: July 2023

Summary: Observers of the Polish-Soviet war of the years 1919-1921 considered it the most significant conflict since the end of WWI. It was common knowledge then that the conflict in question had a considerable influence on the situation of the Mid-  and West European states. It was expected that, should the Red Army have won, the Soviet revolution would have spread as far as the Marne; a reason why the conflict in question was of so much interest to the Norwegian press, considered a mirror of the stand the Norwegian public opinion took as regards the position of the then superpowers towards the said war, the meaning of the war for the Norwegian public opinion as well as Norwegians’s sympathy for or disfavour of the militant parties. This article aims both at presenting the above mentioned issues and juxtaposing them with the political, military, and social questions to date as they appeared in the then Norwegian press. For that purpose my article will also resort to the literature on the subject of the Polish-Bolshevist war.
Królestwo za mgłą – Zofia Posmysz’s Camp Fairy Tale
Authors: Smyk Katarzyna
Published: July 2023

The author analyses the novel Wakacje nad Adriatykiem (Holiday on the Adriatic, 1970) and an extended interview Królestwo za mgłą (The Kingdom Behind the Mist, 2017) with Zofia Posmysz – a prisoner of Auschwitz, Ravensbrück and Neustadt-Glewe, who stylized her concentration camp memories as a traditional folk tale, thus commemorating the fairy tales told by her camp friend Zofia Jachimczak, who did not survive Auschwitz. The author introduces the concept of a camp fairy tale. In the first part of the article, she analyses the elements of folk fairy tale in Posmysz’s texts (space, time, characters, magical objects). In the second part, the author outlines a definition of a separate prose genre – a camp fairy tale, characterized not only by the adaptation of folk fairy tale motifs to concentration camp realities, but also by the fact that this fairy tale, originally told in the concentration camp, is narrated or written down from memory and recounted to listeners by a former prisoner who gives a testimony of life and death in the camp.

The subject of the analysis consists in the sources concerning the ballet Pan Twardowski by Adolf Sonnenfeld. On the basis of the surviving description of the performance from 1898 and the piano excerpts of selected ballet scenes, conclusions were drawn about the Warsaw composer’s work as another variant of the popular Polish legend. The important research context is a reflection on the popular music culture of the second half of the 19th century and contemporary styles of reception
I am the River! Wanda by Zuzanna Orlińska, Literary Tradition and Hydrofeminism
Authors: Bednarek Magdalena
Published: July 2023

The paper presents a short story entitled Wanda by Zuzanna Orlińska as a posthumanist reinterpretation of the traditional ethnocentric legend. Subtle changes in te character’s motivation and expanding the plot of Wanda’s story into two other texts create a new understanding of community (not only a national one), as well as a new model of women’s participation in it. The foundations of this new model are agency, care and interdependence.
The Cemetery and the Fear of the Dead
Authors: Carrassi Vito
Published: July 2023

Fear is a characteristic feature of many legends. And the fear of the death is probably our deepest fear. Death is a crucial event in folk culture, as it triggers an existential crisis which must be duly managed. The living need to distance themselves from the dead in order not to lose their own “presence” in the world. To maintain this distance, people can rely on a dedicated place, the cemetery, where the fear of the dead can be mastered and framed in a sacred dimension. Cemetery may be regarded as a liminal, hybrid space, connecting life and death, the human and the divine, the visible and the invisible. Hence, it can turn into a critical, dangerous place, a “legend landscape”, where odd, mysterious, frightening encounters are possible or, at least, believable. This is especially so if one enters a cemetery at night, when it is forbidden to the living and the darkness creates the perfect stage for fearsome presences. In the ATU 1676B narrative type, an individual bets to enter a cemetery at night in order to show her/his courage and/or refute the belief of the dead as ghosts, but this gamble results in a death from fright. A different case concerns the fate of those who face the night in the cemetery with genuine courage and respect towards the dead, as in a folktale collected by W.B. Yeats (ATU 326), and a (true) story of a woman sleeping in the cemetery (Motif Index C735.2.5). Overall, the cemetery emerges as an ideal setting for a cautionary tale, through which local communities meditate on key issues such as death, fear and belief/non-belief.

Logical Forms, Substitutions and Information Types
Authors: Punčochář Vít
Published: July 2023

This paper explores the relation between the philosophical idea that logic is a science studying logical forms, and a mathematical feature of logical systems called the principle of uniform substitution, which is often regarded as a technical counterpart of the philosophical idea. We argue that at least in one interesting sense the principle of uniform substitution does not capture adequately the requirement that logic is a matter of form and that logical truths are formal truths. We show that some specific logical expressions can produce propositions of different kinds and the resulting diversity of informational types can lead to a justified failure of uniform substitution without undermining the view that logic is a purely formal discipline.

Published: July 2023

Nursing care documentation has been defined as the record of nursing care that is planned and performed to specific patients and by nurses since the early days of Nightingale. To assess Documentation of Implemented nursing process in Jugal Hospital, Harar, Ethiopia. At Jugal hospital in Harar town, 525 kilometers east of Addis Ababa, hospital-based retrospective study design was used and the research took place from January 1st to 27th,2022.The sample size was derived using the single population proportion calculation, the total sample size was 289. IBM SPSS software package version 20.0 (Armonk, NY: IBM Corp) was used to enter, clean, and analyze data.  The overall the implementation of the nursing process in this study is 62.97 %, With regards to the specific components implemented the result shows that 35.99% charts were recorded with assessment and diagnosis part of the nursing process followed by planning 29.07 % whereas implementation and evaluation parts were the least documented in the hospital. In nursing practice, documentation is important; hence it is believed that what is not recorded has not been done and lack of documentation may make it suspicious that they did not do their duty. So the nursing process committees or the hospital matron and the nurse managers at the hospital should conduct routine supportive supervision on NP.
Community water fluoridation and the benefits for children
Authors: Atkinson James A , Jackson Joshua M , Lowery Gary , Taylor Greig D , Rogers Helen J , Vernazza Christopher R
Published: July 2023

Dental caries prevalence in children is high and inequalities are significant, with a major burden for children, families and the health system. Community water fluoridation (CWF) has been shown to be effective and it may reduce inequalities. Despite concerns, there is no evidence that CWF has any major side effects. CWF can cause mild fluorosis of the teeth, but this can be associated with an improvement in quality of life. Economic evaluations of CWF have consistently shown that CWF is cost-saving. Despite the positive evidence, implementation is limited in the UK, and this appears to be due an inconducive political environment, although this is improving.

CPD/Clinical Relevance: Dental professionals should be aware of the benefits of CWF in order to be able to effectively advocate for its implementation.
An unusual appliance: detrimental occlusal consequences of a lack of clinical monitoring
Authors: Radford Philip J , Spencer R James
Published: July 2023

Removable appliances of various designs have been advocated for the treatment of temporomandibular disorders and bruxism. The COVID-19 pandemic decreased the number of clinical examinations undertaken by dentists worldwide, leading to patients seeking solutions to orofacial pain independently of clinicians. Unexpected complications can arise when the design of an appliance does not carefully consider potential occlusal changes that could occur, particularly when there is a lack of clinical monitoring undertaken.

CPD/Clinical Relevance: Poorly designed removable appliances can have an impact on a patient's occlusion, especially without regular monitoring.

Authors: Singh Amrita , Mintoff Jasmine Cachia , Anand Prabhleen
Published: July 2023

This clinical report discusses the presence of a common oral pathology, the mucocele, in an unusual location, the ventral surface of the tongue. These are rare mucoceles associated with the Blandin-Nuhn salivary gland. The likely aetiology, diagnostic features and clinical management and histology are discussed. An 8-year-old male presented at a paediatric practice with a lump under his tongue. A provisional diagnosis of mucocele was made and later confirmed by histology. The lesion was excised completely under local anaesthetic and inhalation sedation.

CPD/Clinical Relevance: A mucocele on the ventral surface of the tongue in a young patient could easily be missed or misdiagnosed.
Human factors in dentistry: Part I. whose fault is a mistake?
Authors: Rasaratnam Lakshmi
Published: July 2023

Dentistry is a profession in which both clinicians and patients hope that mistakes never occur. Unfortunately, mistakes are inevitable in our profession, whether the outcomes are inconsequential or not. Adverse incidents that result in harm to a patient can have long-term repercussions for both the patient and the clinician involved. For clinicians, this could involve litigation from the patient, as well as reprimand from healthcare regulators and colleagues. In addition, the negative psychological implications associated with causing harm or detriment to a patient under our care should not be underestimated. Despite this, there is a risk that our profession focuses on a blame culture when errors occur in our clinical practice, rather than understanding the role of human factors in contributing to such events. This two-part article explores the role of human factors in dentistry, why things go wrong, and how we can learn from mistakes within the profession, providing worked case examples and highlighting 2020 national guidance on human factors in dentistry.

CPD/Clinical Relevance: There may be merit in the dental profession moving away from the blame culture when things go wrong..

Experiences with COVID-19 Stress Among Hispanic/Latino Farmworkers
Authors: Berumen-Flucker Brenda , Galadima Hadiza , Shangani Sylvia , Kekeh Michele , Akpinar-Elci Muge
Published: July 2023

Highlights

The majority of Hispanic/Latino agricultural workers surveyed reported experiencing stress about becoming infected with and contracting COVID-19.

A small proportion of Hispanic/Latino agricultural workers surveyed reported experiencing instances of COVID-19 traumatic stress.

Hispanic/Latino farmworkers reported stress surrounding their ability to financially provide for their families as a result of the COVID-19 pandemic.

Abstract. Hispanics/Latinos, particularly those that identify as foreign-born, are overrepresented in the agricultural sector in the U.S. Over the course of the COVID-19 pandemic, this subpopulation of farmworkers was recognized as an invaluable group of essential workers unable to implement COVID-19 protections. Previously validated COVID-19 stress scale measures were identified, adapted, and translated to collect COVID-19 stress data from Hispanic/Latino agricultural workers in two heavily agricultural counties in northeastern North Carolina. Participants were recruited using purposive convenience sampling. Data collection took place from June to November of 2021. The majority of Hispanic/Latino agricultural workers surveyed reported experiencing worries about catching COVID-19 (92.00%) and being infected with the virus (95.95%). A small proportion of the surveyed population indicated experiencing COVID-19 traumatic stress. More than half of participants were concerned about the impacts COVID-19 would have on their ability to see (53.42%) and provide for their families (58.33%). Farmworkers bore relatively heavy stress burdens associated with the COVID-19 pandemic. Because this group is a vulnerable population at risk for adverse health outcomes, reports numerous barriers to healthcare access, and faces health and safety challenges related to acculturative stress, understanding their experiences with COVID-19 is essential for the development of protective and preventative efforts to improve outcomes among Hispanic/Latino farmworkers. Keywords: Agricultural workers, COVID-19, Farmworkers, Hispanic/Latino, stress.
Timber Transportation Crash and Vehicle Defect Rates in the US South
Authors: Conrad Joseph Locke
Published: July 2023

Highlights

Crash rates among southern log truck fleets were 176% higher than log truck fleets in the Lake States.

Vehicle and driver out-of-service rates were similar among log trucks in the US South, Northeast, Lake States, and West.

The age and condition of log trucks did not explain elevated crash rates in the US South.

Abstract. The US South harvests more than 200 million tonnes of timber annually, nearly all of which is transported from forests to mills by truck. Log truck fleets in the US South have been struggling with rising liability insurance premiums. The goal of this study was to compare crash rates and the condition of log trucks operating in the US South to log trucks operating in other US regions and trucks in other industries. A sample of inspection and crash data were collected from the Federal Motor Carrier Safety Administration. Vehicle and driver out-of-service rates, vehicle defect rates, and crash rates among log truck fleets in the US South were compared to log trucks in other US regions and to 50 large non-log truck fleets. Crash rates among southern log truck fleets were 176% higher than log truck fleets in the Lake States and 48% higher than 50 large non-log truck fleets. Vehicle and driver out-of-service rates were similar among log truck fleets in each region (p > 0.25), but southern logging business fleets had higher vehicle out-of-service rates than 50 large non-log truck fleets (p = 0.02). Driver education, technology implementation, improved fleet maintenance practices, and weight limit parity on interstate highways may improve timber transportation safety. Keywords: Log trucks, Logging accidents, Logging safety, Timber harvesting, Wood supply chain.
CONTOS AFRICANOS E ILUSTRAÇÃO: Uma experiência interdisciplinar
Authors: Tavares de Oliveira Gleciane
Published: July 2023

Esta pesquisa é resultado do trabalho de conclusão de curso de licenciatura em Artes Visuias pela Universidade Federal do Pará (UFPA) no ano de 2020 com objetivo geral o desenvolvimento de uma proposta pedagógica interdisciplinar entre o campo das ilustrações e os contos africanos, na realização de contação de histórias da literatura africana, levando os alunos a produzir ilustrações a partir do livro ilustrado “As meninas negras” (2010). O aporte teórico está fundamentado em autores como Souza (2008) Ivani Fazenda (1993) Walt Fonseca e Cury (2000) entre outros, além da Lei 10.639/2003. Trata-se de uma pesquisa exploratória e descritiva de cunho qualitativo com pesquisa de campo. Os resultados foram obtidos através de atividades direcionadas aos alunos. A partir desses resultados foi possível concluir o quanto as imagens são fundamentais nesse processo de formação da cultura visual da criança, pois através desse repertório imagético elas conseguem constituir suas próprias referências culturais de tal lugar, pessoas, cultura etc. Dentre isso trazemos a reflexão do quanto se faz relevante às escolas adentrarem com propostas de atividades para que visões estereotipadas da cultura africana sejam desconstruídas.
O que eu escuto ou vejo tem a minha cor?
Authors: Tatiane Souza Santos
Published: July 2023

É através da imaginação que a criança projeta e traduz as palavras em imagens que, construídas individualmente, desenvolvem potencialidades e possibilitam a descoberta de suas identidades. A contação de histórias infantis é muito importante para o desenvolvimento do indivíduo, principalmente no que se refere à construção de identidade social, cultural e racial. O objetivo deste trabalho visa analisar a representatividade da criança racializada a partir de um estudo comparado de desenhos realizados a partir da narrativa oral e da narrativa visual e verificar como as crianças racializadas identificam os personagens das histórias infantis através da produção do desenho. Para isso, foi adotado o modelo de estudo comparativo, com base qualitativa e quantitativa, em que serão utilizadas ferramentas de coleta de dados através da contação de histórias para crianças de escola básica que a priori será o CEB - Centro de Escola Básica da UEFS.

Authors: Bárbara Karolynne de Souza Nery  , Livia Dias de Azevedo
Published: July 2023

O Projeto “Novo Centro”, com perspectiva de aplicar características urbanísticas consideradas atualizadas, modificou o desenho de importantes ruas do centro comercial da cidade de Feira de Santana, consequentemente alterando a dinâmica das vias e as suas imagens. Neste sentido, tem-se por analisar as modificações propostas pelo Projeto “Novo Centro” e implicações das suas modificações no desenho da rua Sales Barbosa. Utilizaremos como categoria analítica o desenho urbano e a morfologia urbana, também como importantes lentes para leitura e interpretação do desenho urbano da rua. Após a análise das imagens, pode-se concluir que as transformações aplicadas não condizem com a totalidade das transformações proposta pelos materiais de divulgação do projeto, e que este não buscou inserir nestas transformações aspectos relativos a características culturais locais, seguindo uma lógica de padronização dos espaços urbanos.
Imagens do livro didático de língua portuguesa
Authors: Elisângela Alves Mendes
Published: July 2023

O Desenho é uma forma de manifestação da arte, o artista transfere para o papel imagens e criações da sua imaginação. Um exemplo disso é a imagem, pois é a representação visual de um objeto através de técnicas da fotografia, da pintura, do desenho, do vídeo, dentre outros.  O livro didático de Língua Portuguesa do primeiro ano do Ensino Fundamental possui imagens com linguagem verbal e não-verbal que podem contribuir no processo do ensino e aprendizagem da Alfabetização e Letramento das crianças, visto que a criança quando começa a estudar possui conhecimentos prévios voltados para significados de objetos e lugares.  Sendo assim, esta pesquisa pretende mostrar a importância dos conhecimentos prévios da criança para a aquisição da leitura e da escrita e como as imagens dos Livros didáticos de Língua Portuguesa podem colaborar na alfabetização e letramento destes estudantes na sala de aula. Para tanto, a metodologia utilizada para a realização desta pesquisa é a bibliográfica baseada em um estudo aprofundado da Semiótica. Busca-se verificar quais as contribuições das imagens destes livros do primeiro ano do Ensino Fundamental para o processo do ensino e aprendizagem da alfabetização e letramento.

Published: July 2023

Nesse texto apresenta-se a análise de uma imagem, no caso especifico, uma tirinha que traz a discussão sobre o mito do racismo reverso, a mesma faz parte do caderno de atividades remotas  para o ensino fundamental anos finais (6º ao 9º ano) do município de Santo Estevão-Ba, em especifico o caderno de edição 3 A cara do Racismo no Brasil. Estes cadernos considerados pela rede municipal de ensino de Santo Estevão-Ba, como um material didático pedagógico, são objetos de pesquisa da autora no mestrado acadêmico em educação da Universidade Estadual de Feira de Santana.

 O objeto de análise deste texto é uma tirinha que contém um diálogo entre jovens, a menina Niara, criada pelo cartunista Aroeira, vem trazendo um diálogo onde aparece o questionamento sobre racismo reverso.

Enquanto um recurso imagético, a tirinha analisada possui um potencial discursivo ao tratar da temática racial, como um paradoxo, uma contradição, utilizando de mensagem sarcástica no teor da frase “racismo reverso isso aí” [...], uma leitura simples e provocativa para a compreensão do aluno. A tirinha analisada enquanto imagem demonstra a relação intrínseca entre Educação e Desenho, que deve ser valorizada no campo dos materiais didáticos, e suas discursividades.
Do que (ainda) não é patrimônio
Authors: Pedro Vieira
Published: July 2023

Muitas vezes o patrimônio está em nosso próprio campo de visão, mas não o enxergamos. O campus da Universidade Estadual de Feira de Santana (UEFS), nesta pesquisa, é tomado como um desses objetos, tão presente em nosso cotidiano, mas que (ainda) não é reconhecido como patrimônio cultural. Não se trata apenas de reconhecer suas edificações, mas elementos, materiais e imateriais, que existem em diálogo, em função ou partir desse patrimônio construído, e que colaboram para discussões diversas: culturais, éticas e científicas, e que deveriam justificar sua preservação, como referendado pelos mais recentes estudos no campo do restauro. A pesquisa busca mapear um primeiro conjunto desses elementos, nomeadamente os projetos/desenhos para a construção do Campus, para que então possam ser devidamente trabalhados, colaborando com a construção e preservação da memória da UEFS e com a preservação de seu patrimônio.
Mode analysis and measurement of single-emitter blue diode lasers
Authors: Hu Yaodan , Liu Songjia , Hu Cong , Xiao Yu , Zhou Peng , Peng Hao , Tang Xiahui
Published: July 2023

Recent developments in blue diode lasers have been hindered by the challenge of balancing high power with beam quality. Typically, high-power blue diode lasers exhibit low beam quality due to the output of multiple longitudinal and lateral modes. A promising solution to this problem is to control and shape the blue beam mode output from a single emitter. To achieve this, it is key to have full knowledge of the properties of the output mode under various conditions. In this paper, we explore the mode characteristics of an InGaN single-emitter laser diode that has a typical wavelength of 447 nm (wavelength range: 440–455 nm). We measure and analyze the near-field mode using the box model, finding that the near-field mode excited by the blue diode laser overlapped near the threshold current of 0.32 A. The p=2 order lateral mode of longitudinal mode groups 3 and 4 overlapped with the p=4 order mode of adjacent longitudinal mode groups. Through a Fourier transform of the near-field mode, we obtain the far-field mode and reveal a spatial law of mode distribution that is similar to the near-field mode. As the current is gradually increased and approaches the rated current of the laser diode, the near-field mode continuously has new longitudinal mode groups added to the long-wavelength side of the starting group. We observe an increase in the number of longitudinal mode groups and high-order lateral modes, leading to more mode overlaps. Additionally, we observe a gradual shift in the peak energy of the modes to the long-wavelength side. This study reveals the mode characteristics of broad-area blue diode lasers, providing crucial information to achieve high-quality laser beams in such systems.

Published: July 2023

We demonstrate numerically the feasibility of axial and angular control of the position of a photonic nanojet (PNJ) by lossless phase-only modulation of a fixed Gaussian beam illuminating a fixed 2D circular homogeneous dielectric micro-lens. We furthermore demonstrate that our phase-only modality can be used to calibrate and improve the confinement of PNJ generation.
Flexible optical fiber channel modeling based on a neural network module
Authors: Jiang Rui , Wang Zhi , Jia Tao , Fu Ziling , Shang Chao , Wu Chongqing
Published: July 2023

Optical fiber channel modeling, which is essential in optical transmission system simulations and designs, is usually based on the split-step Fourier method (SSFM), making the simulation quite time-consuming owing to the iteration steps. Here, we train a neural network module termed NNSpan to learn the transfer function of a single fiber (G652 or G655) span with a length of 80 km and successfully emulate long-haul optical transmission systems by cascading multiple NNSpans, which gives remarkable prediction accuracy, even over a transmission distance of 1000 km. Even when trained without erbium-doped fiber amplifier (EDFA) noise, NNSpan performs quite well when emulating the systems affected by EDFA noise. An optical bandpass filter can optionally be added after EDFA, making the simulation more flexible. Comparison with the SSFM shows that NNSpan has a distinct computational advantage, with the computation time reduced by a factor of 12. This method based on NNSpan could be a supplementary option for optical transmission system simulations, thus contributing to system designs as well.
Efficient use of all ports of a 3 × 3 coupler in a nonlinear amplifying loop mirror-based fiber laser
Authors: Nishiura Masanori , Kageyama Ryo , Shioda Tatsutoshi
Published: July 2023

We present an all-polarization-maintaining mode-locked fiber laser based on a nonlinear amplifying loop mirror utilizing a 3 × 3 coupler. A pump laser diode placed outside the cavity pumps both the oscillator and fiber amplifier. This laser configuration effectively utilizes all ports of the coupler, making the laser compact and low-cost, and has great potential as a seed laser for ultrashort pulse lasers.
Low complexity joint clock recovery and adaptive equalization based on a baud-rate timing phase error detector for short-reach digital coherent transmission
Authors: Liu Jingpeng , Li Chengbo , Cui Sheng , Chen Yanan , Tang Jianwei , Zhou Jinhao , Zhou Keji , Dai Jing , Tang Ming
Published: July 2023

Digital coherent receivers adopting joint clock recovery and adaptive equalization (JCA) can avoid failures of the adaptive equalizer (AEQ) or clock recovery algorithm (CRA) due to clock asynchrony and chromatic dispersion (CD). But in the previous JCA scheme, the AEQ has a heavy computational load as it has to generate two samples per symbol (SPS) for the subsequent timing phase error detector (TPED) which is the core of the CRA. Furthermore, the previous JCA scheme cannot compensate for receiver skew or accommodate Nyquist signals with small roll-off factors (ROFs). These shortcomings hinder its practical applications in ultrahigh-speed short-reach coherent transmission requiring low power consumption, high spectral efficiency, whilst being sensitive to receiver skew. To solve this problem, we propose a new JCA scheme by integrating a two-section real-valued (RV) AEQ with an all-digital feedback CRA based on a baud-rate TPED versatile for different ROFs. Experiments for 61-GBaud dual-polarization (DP) Nyquist 16QAM signals with an ROF of 0.01 show that, compared with the previous JCA scheme, the proposed scheme can reduce the AEQ computational load by about 70% for 10-km transmission, whilst improving the receiver sensitivity by more than 1.7 dB for a receiver skew of 1.5 ps. As far as we know, the proposed JCA scheme is the most comprehensive and efficient solution for ultrahigh-speed short-reach coherent transmission where CD, receiver skew, clock asynchrony, and Nyquist signals with small ROFs have to be dealt with.

Laser beam quality is a key parameter for both industry and science. However, the most common measure, the M2 parameter, requires numerous intensity spatial-profiles for its determination. This is particularly inconvenient for modelling the impact of photonic devices on M2, such as metalenses and thin-film stacks, since models typically output a single electric field spatial-profile. Such a profile is also commonly determined in experiments from e.g., Shack-Hartmann sensors, shear plates, or off-axis holography. We introduce and test the validity and limitations of an explicit method to calculate M2 from a single electric field spatial-profile of the beam in any chosen transverse plane along the propagation direction.

The phase separation model for transcription suggests that transcription factors (TFs), coactivators, and RNA polymerases form biomolecular condensates around active gene loci and regulate transcription. However, the structural details of condensates remain elusive. In this study, for Nanog, a master TF in mammalian embryonic stem cells known to form protein condensates in vitro, we examined protein structures in the condensates using residue-level coarse-grained molecular simulations. Human Nanog formed micelle-like clusters in the condensate. In the micelle-like cluster, the C-terminal disordered domains, including the tryptophan repeat (WR) regions, interacted with each other near the cluster center primarily via hydrophobic interaction. In contrast, hydrophilic disordered N-terminal and DNA-binding domains were exposed on the surface of the clusters. Electrostatic attractions of these surface residues were responsible for bridging multiple micelle-like structures in the condensate. The micelle-like structure and condensate were dynamic and liquid-like. Mutation of tryptophan residues in the WR region which was implicated to be important for a Nanog function resulted in dissolution of the Nanog condensate. Finally, to examine the impact of Nanog cluster to DNA, we added DNA fragments to the Nanog condensate. Nanog DNA-binding domains exposed to the surface of the micelle-like cluster could recruit more than one DNA fragments, making DNA-DNA distance shorter.

High-resolution respirometry methods allow for the assessment of oxygen consumption by the electron transfer systems within cells, tissue samples, and isolated mitochondrial preparations. As mitochondrial integrity is compromised by the process of cryopreservation, these methods have been limited to fresh samples. Here we present a simple method to assess the activity of mitochondria respiratory complexes I and II in previously cryopreserved murine skeletal muscle tissue homogenates, as well as previously frozen D. melanogaster, as a function of oxygen consumption.

Mosquitoes transmit pathogens that can cause numerous significant infectious diseases in humans and animals such as malaria, dengue fever, chikungunya fever, and encephalitis. Although the VGG16 model is not one of the most advanced CNN networks, it is reported that a fine-tuned VGG16 model achieves accuracy over 90% when applied to the classification of mosquitoes. The present study sets out to improve the accuracy and robustness of the VGG16 network by incorporating spatial dropout layers to regularize the network and by modifying its structure to incorporate multi-view inputs. Herein, four models are implemented: (A) early-combined, (B) middle-combined, (C) late-combined, and (D) ensemble model. Moreover, a structure for combining Models (A), (B), (C), and (D), known as the classifier, is developed. Two image datasets, including a reference dataset of mosquitoes in South Korea and a newly generated dataset of mosquitoes in Thailand, are used to evaluate our models. Regards the reference dataset, the average accuracy of ten runs improved from 83.26% to 99.77%, while the standard deviation decreased from 2.60% to 0.12%. When tested on the new dataset, the classifier’s accuracy was also over 99% with a standard deviation of less than 2%. This indicates that the algorithm achieves high accuracy with low variation and is independent of a particular dataset. To evaluate the robustness of the classifier, it was applied to a small dataset consisting of mosquito images captured under various conditions. Its accuracy dropped to 86.14%, but after retraining with the small dataset, it regained its previous level of precision. This demonstrates that the classifier is resilient to variation in the dataset and can be retrained to adapt to the variation. The classifier and the new mosquito dataset could be utilized to develop an application for efficient and rapid entomological surveillance for the prevention and control of mosquito-borne diseases.

Background

Timely initiation of antenatal care visits is crucial for ensuring optimal care and health outcomes for women and children. However, late antenatal care initiation among pregnant women in low-income countries including Ethiopia is acknowledged in the literature. Therefore, this study examined why pregnant women initiate antenatal care late in Northeast Ethiopia.

Methods

This study was done using a mixed design approach that included phenomenology and retrospective cross-sectional designs. A retrospective cross-sectional study was deployed among randomly selected 632 medical charts of women who had antenatal care visit in Legambo District primary hospital and health centers. Kaplan Meier curve was used to estimate survival time. Bi-variable and multivariable Cox-proportional hazard regression models were fitted using R-studio-1.2.5033 to identify independent predictors of antenatal care initiation time. Six vignette-based focused group discussions were held with pregnant women who had been purposefully selected. Then, a qualitative content analysis that was informed by the phenomenological theory was done.

Results

This study indicated that only 195 (30.9%) of women timely initiated their antenatal care follow-up. In a survival analysis, all 632 women contributed 12,474 person-weeks giving a timely antenatal care initiation rate of 15.6 per 1000 person-weeks. According to the multivariable Cox regression models, late antenatal are initiation was found among pregnant women with an unknown last normal menstruation period, no living children, no bad obstetric history, not accompanied by their partner during antenatal care visit, and who lived in a >5-kilometer radius of health facility. In a qualitative analysis, being uncertain whether the pregnancy had occurred, believing that they have a very low probability of experiencing any complications, negative experience with healthcare providers, negative influence from their immediate contacts such as the mother and mother-in-law, and socio-cultural beliefs like "Qare" were found as major reasons why they started antenatal care follow-up late.

Conclusion

Most pregnant women in Legambo district, northeastern Ethiopia, initiate their antenatal care visits late. Based on the findings of this study, strengthening the pregnant women identification program and performing regular pregnant women’s conference will help to achieve early initiation of antenatal care visits. To lessen the negative influence of their immediate contacts, it will also good to include these old moms and husbands in the conference of pregnant women.

The performance and reliability of semiconductor devices scaled down to the sub-nanometer regime are being seriously affected by process-induced variability. To properly assess the impact of the different sources of fluctuations, such as line edge roughness (LER), statistical analyses involving large samples of device configurations are needed. The computational cost of such studies can be very high if 3D advanced simulation tools (TCAD) that include quantum effects are used. In this work, we present a machine learning approach to model the impact of LER on two gate-all-around nanowire FETs that is able to dramatically decrease the computational effort, thus reducing the carbon footprint of the study, while obtaining great accuracy. Finally, we demonstrate that transfer learning techniques can decrease the computing cost even further, being the carbon footprint of the study just 0.18 g of CO2 (whereas a single device TCAD study can produce up to 2.6 kg of CO2), while obtaining coefficient of determination values larger than 0.985 when using only a 10% of the input samples.
Haplotype-level metabarcoding of freshwater macroinvertebrate species: A prospective tool for population genetic analysis
Authors: Serrana Joeselle M. , Watanabe Kozo
Published: July 2023

Metabarcoding is a molecular-based tool capable of large quantity high-throughput species identification from bulk samples that is a faster and more cost-effective alternative to conventional DNA-sequencing approaches. Still, further exploration and assessment of the laboratory and bioinformatics strategies are required to unlock the potential of metabarcoding-based inference of haplotype information. In this study, we assessed the inference of freshwater macroinvertebrate haplotypes from metabarcoding data in a mock sample. We also examined the influence of DNA template concentration and PCR cycle on detecting true and spurious haplotypes. We tested this strategy on a mock sample containing twenty individuals from four species with known haplotypes based on the 658-bp Folmer region of the mitochondrial cytochrome c oxidase gene. We recovered fourteen zero-radius operational taxonomic units (zOTUs) of 421-bp length, with twelve zOTUs having a 100% match with the Sanger haplotype sequences. High-quality reads relatively increased with increasing PCR cycles, and the relative abundance of each zOTU was consistent for each cycle. This suggests that increasing the PCR cycles from 24 to 64 did not affect the relative abundance of each zOTU. As metabarcoding becomes more established and laboratory protocols and bioinformatic pipelines are continuously being developed, our study demonstrated the method’s ability to infer intraspecific variability while highlighting the challenges that must be addressed before its eventual application for population genetic studies.
