Effect of channel height on the critical particle diameter in a deterministic lateral device
Authors: Bae Jae Hyun , Zhbanov Alexander , Yang Sung
Published: November 2022

The separation of biological cells or microorganisms in a liquid based on their size by deterministic lateral displacement is widely used in laboratories. The analytical equation for the critical diameter is derived under the assumption that flow between two posts is better described by flow in a rectangular tube than between parallel plates. The height position of the particle is an additional parameter that affects the critical diameter. Preliminary experiments were carried out on the separation of particles in deep and shallow microchannels. This study shows that the critical diameter is not a constant value for a given design but is different on each plane parallel to the top and bottom of the channel. The theoretical model was used to analyze experimental data on the separation of particles larger than 4.2 µm from particles ranging in size from 2.5 to 7.9 µm.

Authors: Nestory Bonaventura , Anasel Mackfallen , Nyandwi Jean Baptiste , Asingizwe Domina
Published: November 2022

Background

Effective vaccine management is essential to maintain the quality of vaccines, minimise wastages, and prevent missed opportunities for vaccination at service delivery points.

Objectives

This study aims to assess vaccine management practices among vaccinators at health facilities in the Morogoro region, Tanzania.

Methodology

A descriptive cross-sectional study design involved health workers from 77 health facilities offering vaccination services. The study population consisted of vaccine handlers and vaccinators working in public health facilities in the Morogoro region. The vaccine management practices were assessed using data collected from ledgers and the Vaccine Information Management System (VIMS). The temperature records were downloaded from the Fridge-tag® 2 and Coldtrace5 devices.

Results

The findings indicated that 65 (84%) health facilities had functional refrigerators and are using power from 26 (34%), 28 (36%), and 23 (30%) of grid electricity, solar, and Liquefied Petroleum Gas (LPG), respectively. Besides, 27 (35%) health facilities have an alternative energy source as a backup. In general, healthcare workers had a good knowledge of cold chain management, including the World Health Organization recommended storage temperatures for vaccines. Furthermore, vaccine stockout was found in 12 (15.6%) health facilities for at least one antigen and 4 (5.1%) health facilities for all five antigens under observation. This current study also revealed that the average calculated vaccine wastage rates for DTP, Measles–Rubella and Rotavirus vaccines were 7%, 19%, and 15%, respectively. More than half of health workers did not perform monthly temperature data reviews. In addition, poor performance led to high wastage rates, including the Rotavirus vaccines, and a change in VVM to discard points. Finally, a small number of 5 (6.5%) health facilities consecutively reported temperature exposure beyond + 8 Celsius (between 5.9 and 281 h).

Conclusions

Healthcare workers’ vaccine and cold chain management knowledge were good for temperature data reading and documentation. However, the practices were poor for some health facilities. The gaps observed in this study inform health managers and policymakers toward establishing interventions to improve health workers' knowledge and practice, including mentorships, supervision, and training to guarantee that each child in all communities reaps the benefits of immunisation services.
Neuroleptic malignant syndrome: a diagnostic dilemma in an unconscious patient—a case report
Authors: Jain Swati , Jain Shruti , Talwar Vandana
Published: November 2022

Background

Neuroleptic malignant syndrome is a clinical condition which has been studied and described well. But history of the patient and the medications he is on are very important to make this diagnosis.

Case presentation

We report the case of a young male who presented with the typical features but lacked the history of medication, hence delaying our diagnosis formation. In-depth history taking is very important in patients who present with unusual symptoms.

Conclusions

Patients on long-term medications, who may develop some side effects due to medication, should always carry a medical card stating their medical history and medication being taken.

Published: November 2022

High-speed visualization of three-dimensional (3D) processes across a large field of view with cellular resolution is essential for understanding living systems. Light-field microscopy (LFM) has emerged as a powerful tool for fast volumetric imaging. However, one inherent limitation of LFM is that the achievable lateral resolution degrades rapidly with the increase of the distance from the focal plane, which hinders the applications in observing thick samples. Here, we propose Spherical-Aberration-assisted scanning LFM (SAsLFM), a hardware-modification-free method that modulates the phase-space point-spread-functions (PSFs) to extend the effective high-resolution range along the z-axis by ~ 3 times. By transferring the foci to different depths, we take full advantage of the redundant light-field data to preserve finer details over an extended depth range and reduce artifacts near the original focal plane. Experiments on a USAF-resolution chart and zebrafish vasculatures were conducted to verify the effectiveness of the method. We further investigated the capability of SAsLFM in dynamic samples by imaging large-scale calcium transients in the mouse brain, tracking freely-moving jellyfish, and recording the development of Drosophila embryos. In addition, combined with deep-learning approaches, we accelerated the three-dimensional reconstruction of SAsLFM by three orders of magnitude. Our method is compatible with various phase-space imaging techniques without increasing system complexity and can facilitate high-speed large-scale volumetric imaging in thick samples.
Identification and focusing of edge diffractions using wavefront attributes
Authors: Znak Pavel , Gajewski Dirk
Published: November 2022

Edge diffractions are more common in 3D seismic data than point diffractions; however, most current studies on processing and imaging diffractions consider point diffractions. We find that the 3D kinematic response of an edge diffractor manifests itself locally as a 2D diffraction for a specific azimuth, which can be uniquely determined using the local characteristics of the wavefronts. This applies to arbitrarily oriented curvilinear edges embedded in inhomogeneous anisotropic media. We further establish a novel 3D time-domain event classification, generalizing the existing 2D technique. A new criterion based on data-derived wavefront curvature matrices allows the unambiguous zero-offset identification of the wave scatterer types: point diffractors, edge diffractors, and reflecting boundaries. We further develop a new data-driven technique of receiver grouping to focus edge diffractions, which contributes to diffraction imaging and tomography. Both proposed methods do not rely on a priori knowledge of the subsurface. Synthetic examples validate these findings.
How We Manage Newly Diagnosed Multiple Myeloma With Circulating Tumor Cells
Authors: van de Donk Niels W.C.J.
Published: November 2022

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology , to patients seen in their own clinical practice.

Careful evaluation of peripheral blood for the presence of circulating plasma cells by morphologic assessment or by flow cytometric analysis is an essential component of the diagnostic workup in all patients with newly diagnosed multiple myeloma (MM) to timely differentiate between MM and primary plasma cell leukemia (pPCL), which is the most aggressive plasma cell dyscrasia. The improvement in survival over time is more modest in pPCL, compared with what has been achieved in MM. pPCL is currently defined by the presence of ≥ 5% circulating plasma cells. However, this cutoff is now challenged by new data, from three large cohorts of patients with newly diagnosed MM, showing that a threshold of 2% circulating tumor cells (CTCs) by flow cytometry can be used to identify a subset of patients with ultra-high-risk MM with comparable prognosis as patients with pPCL. These patients may benefit from more intensified first-line therapies, or from enrollment into specific clinical trials, designed for ultra-high-risk MM and pPCL. Apart from differentiating MM from pPCL, the quantification of CTCs is also useful for risk stratification in MM. The detection of CTCs above a threshold of 0.01%-0.07% (much lower than the threshold to define pPCL) appears to be an independent predictor of poor clinical outcomes in newly diagnosed MM. Additional studies, including transplant-ineligible patients or with incorporation of novel immunotherapies, are needed to identify a definitive prognostic CTC cutoff. The next step will be the incorporation of CTC detection into existing staging systems to improve risk stratification and treatment personalization.
The Missing Matter of Revolution: Hydroelectricity and the Terrain of Postcolonial Politics
Authors: Okoth Christine
Published: November 2022

Through readings of two novels that feature hydroelectric facilities—Peter Abrahams's A Wreath for Udomo and Namwali Serpell's The Old Drift—this article demonstrates how each text grapples in very different ways with the tensions between extractive infrastructures and revolutionary politics. Focusing on a hydroelectric facility yet to be constructed, A Wreath for Udomo reaches for the formal capacities of the novel to stage how the process of formal enclosure specific to and resulting from economic planning results in an analytic enclosure that slowly undoes the possibility of revolutionary anti-capitalism. The Old Drift enacts, I will suggest, an important alternative to the epistemological enclosure foreseen in Abrahams's much earlier novel. Serpell's novel leverages the critical capacity of the historical, genealogical novel to evade the analytical impediments produced by the structure of the hydroelectric dam and the form of economic thinking it both metonymizes and from which such projects result. By constructing parallel revolutionary methods on the levels of characters and readers and content and form, The Old Drift effectively recasts the problem of revolution not in terms of ideological contradiction, as Abrahams does, but as a tension between the constituent components of novelistic and revolutionary totality.
Partisan Fertility and Presidential Elections
Authors: Dahl Gordon B. , Lu Runjing , Mullins William
Published: November 2022

Changes in political leadership drive sharp changes in public policy and partisan beliefs about the future. We exploit the surprise 2016 election of Trump to identify the effects of a shift in political power on one of the most consequential household decisions: whether to have a child. Republican-leaning counties experience a sharp and persistent increase in fertility relative to Democratic counties, a shift amounting to 1.2–2.2 percent of the national fertility rate. In addition, Hispanics see fertility fall relative to non-Hispanics, especially compared to rural or evangelical Whites. (JEL D72, J13)

Published: November 2022

Objetivo: analisar o perfil epidemiológico dos casos de neoplasia do sistema respiratório que foram diagnosticados e tratados nos anos de 2017 a 2019 e comparar com os casos ocorridos durante a pandemia da COVID-19 no Brasil. Método: estudo transversal com dados de neoplasia maligna da traqueia, dos brônquios e dos pulmões fornecidos pelo Departamento de Informática do Sistema Único de Saúde. Os casos foram coletados e analisados conforme a modalidade terapêutica e o sexo, por meio da incidência anual para cada região brasileira, comparando-se o período da pandemia e os anos de 2017, 2018 e 2019. Resultados: durante a pandemia, nos casos de neoplasias do sistema respiratório, que acometeram o sexo masculino, foram observadas reduções da realização de procedimentos terapêuticos em todas as regiões brasileiras, notando-se, principalmente, diminuições de 68,22%, 19,58% e 57,24% dos casos tratados com cirurgias, quimioterapia e radioterapia na Região Nordeste. Nos casos de neoplasias que acometeram o sexo feminino, foram detectados aumentos de cirurgias e reduções de radioterapia em todas as regiões federativas, notando-se, principalmente, um aumento de 64,03% e uma redução de 59,73%, respectivamente, dos casos tratados com cirurgia no Centro-Oeste e com radioterapia no Sudeste. Conclusão: o remanejamento dos tratamentos está correlacionado aos aumentos e às reduções dos casos tratados de neoplasias do sistema respiratório. Nesse contexto, os serviços de saúde devem adotar medidas para reduzir a exposição e a contaminação dos indivíduos com a COVID-19, de modo que os tratamentos oncológicos não sejam afetados, e evitar desfechos graves.

Published: November 2022

Background: The loss of E-cadherin expression and the induction of N-cadherin are known as hallmarks of the epithelial-to-mesenchymal transition, an essential initial step in the process of metastasis in solid tumors. Although several studies have reported expressions of these cadherins in patients with multiple myeloma (MM), their clinical significance is unknown as MM cells are non-epithelial.

Methods: In this study, we examined the expression of E- and N-cadherins by immunohistochemistry using bone marrow (BM) biopsy specimens from 31 newly diagnosed MM patients and in subsequent biopsy specimens from six of these.

Results: Negative E-cadherin expression on BM myeloma cell membranes was significantly associated with the presence of soft-tissue masses arising from bone lesions and breaking through the cortical bone, referred to as extramedullary disease (EMD).

Conclusions: Given the aggressive nature of EMD, our study suggests that screening for E-cadherin using BM immunohistochemistry is one measure that could predict the development of EMD in patients with MM.

Published: November 2022

Background: The objective of this anatomical study was to perform the morphometry of dried lumbar vertebrae in human cadavers.

Methods: This study utilized 200 adult human cadaveric dried lumbar vertebrae. The digital Vernier calipers was used to perform the measurements. The height, antero-posterior length, transverse length of the body of the vertebrae, interpedicular distance at the lateral ends, lamina length, height and thickness, superior and inferior articular facet height and width, mid sagittal and transverse diameter of vertebral foramen, height, width and thickness of the pars inter-articularis were measured.

Results: The vertebral body’s anteroposterior length was more at the lower border than at the superior border (p < 0.01). The length of lamina was higher over the right in comparison to the left (p < 0.001). The height of lamina, width of inferior articular facet, diameter of lateral recess and thickness of pars inter-articularis were greater for the left sided specimens (p < 0.01). The statistical significance was not observed for the comparison of the remaining parameters (p > 0.05).

Conclusion: This anatomical study offered several dimensions of lumbar vertebrae, which are essential in the surgical practice. The implants at the lumbar vertebrae need to be manufactured based on the anatomical dimensions of that particular sample population.
Leveraging biochemical reactions to unravel functional impacts of cancer somatic variants affecting protein interaction interfaces
Authors: Raimondi Francesco , Burkhart Joshua G. , Betts Matthew J. , Russell Robert B. , Wu Guanming
Published: November 2022

Background: Considering protein mutations in their biological context is essential for understanding their functional impact, interpretation of high-dimensional datasets and development of effective targeted therapies in personalized medicine.

Methods: We combined the curated knowledge of biochemical reactions from Reactome with the analysis of interaction-mediating 3D interfaces from Mechismo. In addition, we provided a software tool for users to explore and browse the analysis results in a multi-scale perspective starting from pathways and reactions to protein-protein interactions and protein 3D structures.

Results: We analyzed somatic mutations from TCGA, revealing several significantly impacted reactions and pathways in specific cancer types. We found examples of genes not yet listed as oncodrivers, whose rare mutations were predicted to affect cancer processes similarly to known oncodrivers. Some identified processes lack any known oncodrivers, which suggests potentially new cancer-related processes (e.g. complement cascade reactions). Furthermore, we found that mutations perturbing certain processes are significantly associated with distinct phenotypes (i.e. survival time) in specific cancer types (e.g. PIK3CA centered pathways in LGG and UCEC cancer types), suggesting the translational potential of our approach for patient stratification. Our analysis also uncovered several druggable processes (e.g. GPCR signalling pathways) containing enriched reactions, providing support for new off-label therapeutic options.

Conclusions: In summary, we have established a multi-scale approach to study genetic variants based on protein-protein interaction 3D structures. Our approach is different from previously published studies in its focus on biochemical reactions and can be applied to other data types (e.g. post-translational modifications) collected for many types of disease.
Multi-layer modelling of masonry structures strengthened through textile-reinforced mortar
Authors: Boem Ingrid
Published: November 2022

Background

Textile-reinforced mortar (TRM) is an innovative strategy for the reduction of the seismic vulnerability of existing masonry buildings consisting in the application on the masonry surface, of a mortar coating with fiber-based grids or textiles embedded. The paper presents the calibration and application of a simplified modelling approach, based on multi-layered elements, for the simulation of existing masonry elements and structures strengthened through TRM.

Methods

The strengthened masonry is modelled by using 20-nodes brick elements formed by a stacking sequence of layers representing the different material components (the masonry, the mortar coating and the embedded reinforcement). The nonlinear behavior of the materials is considered and calibrated on the basis of experimental characterization tests on individual components available in the literature. The simplified assumption of perfect bond among layers is considered.

Results

Non-linear static analyses are performed on samples of increasing complexity: elementary panels, structural elements (piers and spandrels) and a pilot building. The results of some tests on TRM strengthened masonry, available in the literature, are considered to assess the model reliability in terms of capacity curves and collapse mode. The model is capable of detecting the typical failure mechanism of existing masonry, namely the diagonal cracking, the in-plane bending and the out-of-plane bending and is able to detect the activation also of mixed failure modes, that often occur in actual configurations.

Conclusions

Given the coarse mesh size and the smear plasticization assumption, the model is not suitable for the rigorous reproduction of individual cracks but represents a good compromise between the goal to grasp the structural performances at the wide scale, including failure modes, and the analysis optimization.
Detection and public health risk assessment of microplastics in disposable (PET) bottled water produced and sold locally in the Aegean Region
Authors: Yozukmaz Aykut
Published: November 2022

Intensive use of plastic has led to the accumulation of plastics in all ecosystems and inevitable environmental pollution. Plastic wastes have undergone structural degradation with the effect of environmental factors and have been disintegrated into nano and microparticles; thus, might accumulate in living organisms and reach unpredictable levels in the food chain. In recent years, the impacts of these particles called "microplastics" (MP’s) have become one of the most important issues in the scientific world. The aim of this study is to evaluate the possible presence of MP’s in drinking water, that represents the most important nutrition element for human beings. For this purpose, samples of 6 different brands of disposable (PET) bottles produced and sold locally were examined. A total of 36 samples in bottles with 2 different volumes were analyzed in accordance with international standards and the results were evaluated. As a result of the study, the presence of MP’s was detected in all samples analyzed. A total of 207 MP’s were found in 36 samples. As a result of the analysis, a mean of 7.35 ± 9.66 MP L-1 particles was detected. It was determined that the most dominant type in terms of shape was fiber (91%), the most dominant type in terms of color was blue (57%) and the most dominant type in terms of size was 0.1-1 mm (71%). When Estimated Daily Intake (EDI) rates were calculated for public health risk assessment, it was determined that the most affected group is the 3-6 age group (EDI (avg) = 0.42). The importance of making recycling more widespread, raising awareness of consumers and making the necessary legal regulations on the issue was emphasized in order to reduce the problem at its source.

This study aimed to disclose the spatial variability in the lagenar otolith (asteriscus) dimensions-total length relationships generated for four Prussian carp, Carassius gibelio (Bloch, 1782) populations (Altınkaya Dam Lake, Bafra Fish Lakes, Lake Ladik and Lake Simenit) in Samsun Province, Türkiye. Relationship between length and weight of the fish was also described for each population. Samples were obtained from commercial fishermen in different periods between February 2017 and March 2018. The length, height, and weight of each otolith were determined. A non-linear function was used to define allometric relationships between asteriscus measurements and body size. The slopes of the regressions acquired for the right and left otoliths at each sampling site did not show any significant difference. All of the relationships were found to be statistically significant (P<0.001). The r2 values ranged from 0.61 to 0.95, and the mean values of the percent prediction error varied from 3.10 to 7.45. The ANCOVA test determined significant spatial differences in regression slopes for the three otolith variables. Our findings revealed that otolith development reflected somatic growth, but this varied by sampling area.

Published: November 2022

This study's objective was to develop a model to determine dye adsorption efficiency of Treptacantha barbata (Stackhouse) Orellana& Sansón, 2019 (formerly Cystoseira barbata (Stackhouse) C. Agardh, 1820). During the experiments, treatment groups, such as initial dye Methylene Blue (MB) concentration (0.1-10.0 mg L-1), contact time (5 to 1440 min) and adsorbent dosage (0.1-2 g) were applied. Scanning electron microscopy, energy dispersive X-ray, and Fourier Transform Infrared Spectroscopy were used to analyze the adsorbent. T. barbata was found to be quite successful in removing dye (69% -100%) for all experiments, and the qe values increased with the increased the initial dye concentration. Very rapid dye removal was detected during the first contact time, especially up to 15 min. Isotherms, kinetics, and regression models were applied to the batch experimental results. The results displayed that adsorption process was suitable with the Langmuir isotherm model (R2: 0.97).
Forecasting sea surface temperature with feed-forward artificial networks in combating the global climate change: The sample of Rize, Türkiye
Authors: Akkan Tamer , Mutlu Tanju , Baş Eren
Published: November 2022

The increase of the world population, especially in the global competition, together with the increasing use of fossil fuel resources to meet energy needs, leads to more greenhouse gases (more than one CO2, methane etc.) emissions and the global climate crisis. In this process, changes in meteorological events such as temperature, precipitation, and wind, attract attention moreover but when considered as a whole, we know that these negative changes in the ecosystem negatively affect many living groups. Sea Surface Temperature (SST) as measured meteorologically is the most important environmental parameter where these changes are monitored and observed. It draws attention to the fact that changes in SST are not limited to living organisms as habitats, but also catalyze many chain reactions, especially socio-economic impacts. Therefore, much of the work is devoted to forecasting studies to adapt to changing habitats and take the necessary precautions against potential risks. Feed-forward artificial neural networks have been commonly used to address these emerging needs. Artificial neural networks, which are a simple imitation of the human neurological system, have been used as an artificial intelligence method in forecasting problems due to their superior performance and not having the limitations of classical time series. In this study, the forecasting of the time series of monthly mean SST temperature obtained from Rize station between the years 2010 and 2020 is performed by using feed-forward artificial neural networks, and the forecasting performance of the corresponding time series is compared with many forecasting methods with different characteristics. The comparison of the methods used the mean square error and mean absolute percentage error criteria, which are commonly used in the forecasting literature. The analysis results showed that the analysis results obtained with the feed-forward artificial neural networks have the best prediction performance. As a result, it can be stated that the sea surface temperature can be forecasted with a very high accuracy using the feed-forward artificial neural networks.

Published: November 2022

The aim of this study was to evaluate the relationship between attitudes toward weight loss, taking into account: the motivating factors that determine the desire to attempt weight loss; the level of well-being and degree of motivation before and during the weight loss attempt; changes in attitudes after an unsuccessful weight loss attempt; the state of well-being after the completed weight loss attempt and the degree of severity of disordered eating according to the TFEQ-13 questionnaire. The study was conducted among 600 female users of forums for people with excessive weight. The research method used in this study was the author's questionnaire and the standardized Three-Factor Eating Questionnaire. A general survey questionnaire serving as a working tool was sent by Computer-Assisted Web Interview to community groups. The predominant group of respondents cannot even count the weight reduction attempts they have made during their lives (31%). Three attempts were made by 29% of respondents, and two attempts by 17%. Attempts to lose weight most often involved increasing current physical activity (overall responses), reducing the caloric content of meals (26%), and improving current eating habits (22%). Most people reduced their body weight from 6 kg to 10 kg (29%) or from 3 to 5 kg (27%). It was found that low a risk of aggravation was diagnosed in 45.5% of people, moderate in 44.5, and low in 10%. For lack of control over eating – a low risk was observed in 15.5% of people, moderate in 68.5% of people, and high in 16%. Evaluating eating under the influence of emotions, the highest risk of the studied phenomenon was observed in 50.5% of people, moderate risk in 36.5% of people, and low risk in 13% of people. The level of motivation significantly decreased when trying to reduce weight. No significant deterioration in well-being was observed before and during the weight loss attempt.

Published: November 2022

Vascular malformations of the muscle are rare non-proliferative vascular lesions, and few case reports have described intramuscular vascular malformations in the upper extremities. Vascular malformations of the muscle may produce musculoskeletal deformities due to muscle contracture. Symptomatic intramuscular vascular malformations are commonly treated with surgery and interventional management. We report a vascular malformation that could not be completely resected. It caused adduction contracture of the thumb in the hand. Sclerotherapy was performed before surgery, but the contracture did not improve. Thus, we additionally performed adductor tenotomy. There was no evidence of recurrence during 6 months of follow-up.
Challenges and critical success factors of digital communication, collaboration and knowledge sharing in project management virtual teams: a review
Authors: Swart Kurt , Bond-Barnard Taryn , Chugh Ritesh
Published: November 2022

Technological advancements, globalization, and the COVID-19 pandemic have transformed digital communication into a central tenet of many project management virtual teams (VTs). However, successful VTs are dependent on communication, collaboration and knowledge sharing among team members. Through a systematic literature review, this study investigates the challenges and critical success factors of digital communication, collaboration, and knowledge sharing in project management VTs. As a result, eight key common themes were identified - trust, cultural diversity, collaboration tools and technology, communication and knowledge hoarding, leadership, psychological safety, communication guidelines and training, and resource planning. Furthermore, given the geographically dispersed nature of VTs, they face additional challenges than teams that interact face-to-face (in-person). Therefore, mitigating the challenges by focusing on the identified themes could lead to project success.
(Un)Mapping trajectories of fatness: a critical account of fat studies’ origin story and the reproduction of fat (white) normativity
Authors: Zerafa Samantha Rose Ruth
Published: November 2022

Origin stories set the stage for the development of a field of study and are integral to the ways they grow and shift. Similar to other reclamation projects, fat studies aims to rewrite the history of ‘fat’ by subverting its violent use for surveillance and control, and positioning it as a natural human characteristic. Its origin story is inextricably linked to the activism and scholarship of white and white-passing women, and is often located in gendered expectations of the ‘appropriate’ feminine body. As a result, the racial origins and functionings of fatphobia become erased and create a normative fat subject that is typically cisgender, female and white, which is reproduced in much of the research emerging from the field. I, along with other fat activists and scholars, propose a fundamental shift towards an intersectional fat studies, with race as an entry point to analysis towards rewriting the field’s history and presence.

Las voces de Lautréamont
Authors: Mallart Myriam
Published: November 2022

The history of the reception in Castilian of Lautréamont’s Chants du Maldoror, a forgotten book then, intertwines with it’s rediscovery by André Breton and the surrealist movement. Both translations of the book, which are very different from a linguistic point of view, above all in what concerns the critical work surrounding the text, happen to coincide with two essential moments of the surrealist’s reception: the “Roaring Twenties”, which were years of an enormous surrealist activity, and the sixties, a decade in which the movement itself became part of the “History of Literature”. In the foreword of 1925’s version, Ramón Gómez de la Serna nourishes from surrealist’s knowledge and opinions on Lautréamont’s figure, while forty years later, Peligrini’s introduction and notes show that the author of the Chants was already considered a “classic".
AGAINST SPANISH CONSCIENCE’: THE TRANSLATION OF NORTH-AMERICAN CLASSICS IN POST-WAR SPAIN (1950S & 1960S)
Authors: Teresa Requena Gemma López
Published: November 2022

The period before the Spanish Civil War witnessed some translations into Catalan of North-American authors such as Walt Whitman, Mark Twain, Edgar Allan Poe and Nathaniel Hawthorne. It is over the 1930s, however, that other big names of North-American literature –such as William Faulkner and Ernest Hemingway- reach high levels of popularity on Spanish soil. What happens much later with the reception of these authors? Our article will explore the translations of these and other North-American authors which appeared over the end of the Spanish Civil War to the end of the 1950s, a period of cnsolidation of the United States as a global economic power. Our proposal is to research the selection of titles edited and translated over these two decades (40s and 50s) with a view of demonstrating that they conform an intricate wave of thought on the part of vocational editors who took care of every single detail in the editing process, and who had to confront serious logistic and ideological problems to boot. In order to carry out our research, we have been working with the catalogues of Janés, Caralt, Seix Barral and Destino.
CROLLA, Adriana Cristina (UNL): Traducción literaria en Argentina. Tradición, matrices culturales y tra-dicciones en perspectiva comparada
Authors: Crolla Adriana Cristina
Published: November 2022

El advenimiento de la aldea global y los procesos acaecidos durante la segunda mitad del S.XX han provocado un auge notable de estudios y una redefinición de función que cumple la traducción como práctica social e indicador de tradiciones de lecturas y como el paradigma de toda práctica de intermediación lingüística, semiótica y cultural. Re-visión sobre todo de: 1) el papel del traductor en las operaciones de escritura y re-escritura en el entramado cultural; 2) la compleja relación  que se establece entre textos y versiones, 3) la incidencia de la traducción en la conformación o redefinición de una tradición o sistema literario y 4) el papel que juegan los marcos culturales de partida y de llegada en la determinación de su validación. Desde los parámetros de los estudios comparados es interesante analizar estas operaciones por el modo en que, aún la traducción intralingüística, permite hacer visibles fenómenos de interferencia y de intraducibilidad que pueden sólo ser explicados en función del contexto y de las matrices culturales que dan marco de referencia. Proponemos entonces, desde el juego homofónico de "traducción, tradición y tra-dicción", analizar algunos casos paradigmáticos que ponen de relieve la incidencia de las matrices culturales europeas en la conformación idiosincrática argentina y los efectos diversos de lectura que este fenómeno inter-fiere.

MUÑOZ CALVO, Micaela (U. Zaragoza): “The Old Man and the Sea”: Traducción y recepción en España.
Authors: MUÑOZ CALVO Micaela
Published: November 2022

Este estudio presenta las ediciones y traducciones que se han hecho, en las distintas lenguas de la geografía Española, de El Viejo y el Mar, desde su publicación en 1952. El análisis de The Old Man and the Sea y de algunas de sus traducciones al castellano nos permiten mostrar si el lector español, que en su mayor parte ha accedido a esta obra de Hemingway a través de sus traducciones, ha podido y puede aproximarse a las diferentes lecturas del hermoso texto original de Hemingway.
CARLUCCI, Laura (UGR): Recepción literaria, traducción y discurso fílmico en la audiodescripción de “El Gatopardo”.
Authors: CARLUCCI Laura
Published: November 2022

El punto de partida de este artículo es la novela Il Gattopardo de Giuseppe Tomasi di Lampedusa. Tras estudiar la recepción española de la obra literaria, pasaremos a analizar brevemente su transposición cinematográfica de la mano del gran director neorrealista Luchino Visconti. Por último, examinaremos la versión audiodescrita de la película para el público invidente, llevada a cabo en 2006 para la ONCE. En este sentido, analizaremos el guion audiodescrito, es decir, el texto que comenta y describe todos aquellos elementos visuales que desempeñan un papel importante dentro de la película, con el fin de permitir a las personas con discapacidad visual acceder a ellos, oyendo lo que no pueden ver. Se analizarán los diferentes trasvases entre los aspectos literarios y cinematográficos y se determinará en qué medida estos transvases repercuten en la audiodescripción.
MUÑOZ RAYA, Eva (UGR): Traducción y adaptación del teatro italiano en la España democrática (1975-2000).
Authors: MUÑOZ RAYA Eva
Published: November 2022

El estudio se ocupa de la traducción del teatro italiano en el último cuarto del siglo XX en España. El análisis muestra que no se puede hablar de un modelo de traducción exclusivamente vinculado a la tipología textual; en cambio sí se advierte la existencia de traducciones de varios tipos, clases o naturaleza, dependiendo de la finalidad o la situación comunicativa del destinatario, subrayando así la dependencia y el papel central del sistema meta en el proceso de trasvase de la lengua origen a la lengua meta, y ello se muestra tanto en las traducciones como en las versiones o adaptaciones cotejadas.
La traducción y su papel hibridizante dentro de la semiosfera: Fenollosa – Hearn – Pound – Noguchi
Authors: Penas-Ibáñez Beatriz
Published: November 2022

En este artículo tomaremos, como punto de partida, el factor diversidad quecaracteriza la semiosfera (Lotman [1984] 2005) y define el complejo entramado derelaciones de naturaleza intracultural que prefiguran y posibilitan la relaciónintercultural, especialmente por medio de la traducción. La semiosfera es el sistemaen el cual los textos estándar de la cultura ocupan lugar preeminente en la jerarquíaque define el segmento educado (High) de esa cultura frente a otros segmentos osubculturas (Low). Dentro de una semiosfera el estándar es la norma de referenciapara la interpretación del valor simbólico de la diferencia subcultural (High vs. Low)existente en la intracultura y que condiciona la forma de su transferencia a otracultura. Por una parte incidiremos en la necesidad radical de reconceptualizar latraducción per se como proceso posibilitador de la comprensión de lo diverso desdeel interior del discurso y a través de lo diverso del discurso y, por tanto, comoproceso de gestión discursiva tendente a la convergencia interpretativa (intertextual,intersubjetiva, intercultural) de enunciados en principio divergentes en la forma enque sus diferentes códigos verbales y culturales articulan el sentido. Por otra parteseñalaremos la importancia del traductor individual dentro de estos procesos.Plantearemos el rol primordial que juegan los traductores en la modernizaciónde sus correspondientes semiosferas, y lo haremos a través de un ejemplo muysignificativo que relaciona el nacimiento del Imaginismo y Modernismo Anglonorteamericanoal cierre de la época Meiji en Japón o de la etapa Victoriana en GranBretaña. No fue accidental que, tras varias décadas de nueva producción detraducciones (del japonés al Inglés y del Inglés al Japonés) por parte de traductorescomo Noguchi, Hearn, Fenollosa, o Ezra Pound, tuviese lugar la eclosión de unasliteraturas, la Japonesa y la Anglo-norteamericana, plenamente modernizadas yrenovadoras. Mientras traducían, estos traductores fueron aprendiendo de latextualidad Fuente a escribir textos Meta cuyas formas híbridas les enseñaban, a ellos y a sus compañeros de profesión literaria, a renovar los estándares de sussemiosferas nativas.

Published: November 2022

We demonstrate infrared supercontinuum generation in 4H-SiC on
insulator slab waveguides. The effect of waveguide geometry parameters
on dispersion is investigated to switch the zero-dispersion wavelength
close to the pump wavelength. The 1 cm long 4H-SiC waveguide is
pumped by 100 fs pulses at 1550 nm with 2000 W
peak power, and the generated supercontinuum extends from

(at 20 dB level). This work
shows that 4H-SiC has significant potential as on-chip photonic
sources for spectroscopic applications in infrared wavelengths.
High-precision polarized dual low-coherence scanning interferometry for rapid step height measurements
Authors: Park Hyo Mi , Seo Seon Ile , Cho Min Seo , Joo Ki-Nam
Published: November 2022

In this investigation, we propose a polarized dual low-coherence scanning interferometer. The spatial phase-shifting technique and the concept of the dual low coherence are adopted to overcome the scanning conditions of typical low-coherence scanning interferometers and reduce the measurement time. In the proposed interferometer, the scanning interval is not critical because the visibility and the phase are immediately obtained during a scanning procedure, and the whole scanning distance can be significantly reduced by the dual low coherence. To verify the system performance, the surface profiles of a plane mirror and a step height specimen were measured, and it was confirmed that the whole scanning distance was reduced 10 times without any scanning conditions.

In-line and off-axis polarization-selective holographic lenses recorded in azopolymer thin films via polarization holography and polarization multiplexing

Published: November 2022

Polarization-selective diffractive in-line and off-axis lenses are recorded in
azopolymer thin films using polarization holography. A simple, yet
efficient, and to the best of our knowledge, new method is used to
suppress the surface relief grating formation and to improve the
polarization properties of the lenses. The in-line lenses are
converging for right circularly polarized (RCP) light and diverging
for left circularly polarized (LCP) light. Bifocal off-axis lenses are
recorded by polarization multiplexing. By rotating the sample at 90°
between the exposures, the two focal points of these lenses are
located in orthogonal directions

O

x

and

O

y

, so we can refer to these novel
lenses as 2D bifocal polarization holographic lenses. The light
intensity in their focuses depends on the reconstructing light
polarization. According to the recording scheme, they can either reach
maximum intensities simultaneously (for LCP or RCP), or alternatively,
one of them can be at maximum for LCP, while the other for RCP. These
lenses may be used as polarization controllable optical switches, in
the field of self-interference incoherent digital holography or for
other photonics applications.
Imaging acoustic standing waves in the presence of flowing gas

Published: November 2022

A method for imaging an acoustic standing wave in the presence of
flowing gas is described. The optical power at the acoustic frequency
in each pixel of a series of high-speed transmission electronic
speckle pattern interferograms is used to map the steady-state
pressure variations of an acoustic standing wave. The utility of the
process is demonstrated by imaging the standing wave inside a
transparent organ pipe.
