The first, to our knowledge, successful laboratory implementation of an approach to image winds using simultaneous (as opposed to sequential) fringe imaging of suitable isolated spectral emission lines is described. Achieving this in practice has been a long-standing goal for wind imaging using airglow. It avoids the aliasing effects of source irradiance variations that are possible with sequential fringe sampling techniques. Simultaneous fringe imaging is accomplished using a field-widened Michelson interferometer by depositing phase steps on four quadrants of one of the mirrors and designing an optical system so that four images of the scene of interest, each at a different phase, are simultaneously produced. In this paper, the instrument characteristics, its characterization, and the analysis algorithms necessary for use of the technique for this type of interferometer are described for the first time, to the best of our knowledge. The large throughput associated with field-widened Michelson interferometers is sufficient for the spatial resolutions and temporal cadences necessary for ground based imaging of gravity waves in wind and irradiance to be achieved. The practical demonstration of this technique also validates its use for proposed monolithic satellite instruments for wind measurements using airglow on the Earth and Mars.
Phase retrieval for objects in rain based on a combination of variational image decomposition and variational mode decomposition in FPP
Authors: Hong Nian , Tang Chen , Xu Min , Lei Zhenkun
Published: July 2022

As far as we know, there is no paper reported to retrieve the phase of an object in rain by the fringe projection profilometry (FPP) method. The fringe projection pattern taken in rain contains much rain noise, which makes it difficult to accurately retrieve the phase of the object. In this paper, we focus on the phase retrieval of the object in rain by the FPP method. We first decompose the original fringe projection pattern into a series of band-limited intrinsic mode functions by the two-dimensional variational mode decomposition (2D-VMD) method. Then we screen out fringe-associated modes adaptively based on mutual information and reconstruct the fringe projection pattern. Next, we decompose the reconstructed fringe projection pattern by the TGV-Hilbert-BM3D variational model to obtain the de-rained fringe component. Finally, we use the Fourier transform method, phase unwrapping method, and carrier-removal method to obtain the unwrapped phase. We test the proposed method on three fringe projection patterns taken in simulated rain weather, and we compare our proposed method with the phase-shifting method, windowed Fourier method, morphological operation-based bidimensional empirical mode decomposition method, 2D-VMD method, and the TGV-Hilbert-BM3D method. The experimental results demonstrate that, for the first time to our knowledge, our method can effectively retrieve the phase of an object in rain from a single fringe projection pattern.
Internal displacement measurements based on color fluorescent speckle pattern by multispectral stereo-DIC and refractive index correction

Published: July 2022

Fluorescent digital image correlation (DIC) is becoming popular for measuring 3D profiles and deformations in external surfaces. However, the simultaneous monitoring of interior layers is highly challenging due to the penetrability and refraction of light using monochromatic fluorescence. We propose a color fluorescent speckle pattern (CFSP) method for measuring the internal displacement of transparent objects based on multispectral stereo-DIC and refractive index correction. During sample fabrication, fluorescent speckle patterns exciting different colors are fabricated on both the surface and interior layers of objects. A virtual color stereo-DIC system is utilized to capture the CFSP on the surface and interior layers simultaneously from two different perspectives. Different color channels are practically equivalent to synchronized monochrome vision systems, having separate CFSP in external and internal measurements. In multispectral stereo-DIC calculation, the external surface is initially reconstructed through one channel of the system even if the surface is non-planar. Based on Snell’s law and the CFSP method, the internal layer is then reconstructed and corrected by establishing the geometry of the refractive stereo-DIC through another channel. The relative error of the thickness between two planar layers was proved to decrease from 33.4% to 0.7% after refractive index correction. Further experimental results validate the efficacy of this method for correcting the profile of the non-planar arc profile and determining the internal deformations of disc materials.
Broadband intermodal fiber interferometer for sensor application: fundamentals and simulator
Authors: Petrov A. V. , Bisyarin M. A. , Kotov O. I.
Published: July 2022

An intermodal fiber interferometer using the light from an incoherent broadband source has been considered analytically and implemented as a laboratory device. It was shown that this optical scheme could be used to measure external perturbations that cause a change in the optical length of a multimode fiber. The use of an optical spectrum analyzer and correlation functions approach in extracting the utility signal made it possible to achieve a linear response to the measured external perturbation and effective fading mitigation. A pair of integral coefficients was introduced: the contrast coefficient for characterization of the coherency of the operation regime, and the fading coefficient for estimating the signal stability against non-signal parasitic influences. Analytical expressions for the utility signal parameters were derived in dependence on the parameters of the light source, multimode fiber, and optical spectrum analyzer. The relationships among fiber length, width of the light source spectrum, and frequency resolution of the optical spectrum analyzer were stated for the optimum regime of interferometer operation. The simulation of the external perturbations performed at the elaborated device proved the applicability of the proposed scheme as a sensor of various physical quantities.

Published: July 2022

Two-wave mixing adaptive interferometer based on a liquid crystal light valve with a semiconductor GaAs substrate is realized and studied at 1064 nm wavelength. The local response of the dynamic hologram recorded in the liquid crystal layer of the light valve allows for detection of small phase modulations of the object beam. The characteristics of the interferometer are estimated experimentally. The temporal adaptability lies in the subsecond range. The large optical nonlinearity of the cell is favorable for measurements of small displacements with high sensitivity.
Environmental effects on the spread of the Neolithic crop package to South Asia
Authors: Gregorio de Souza Jonas , Ruiz-Pérez Javier , Lancelotti Carla , Madella Marco
Published: July 2022

The emergence of Neolithic economies and their spread through Eurasia was one of the most crucial transitions of the Holocene, with different mechanisms of diffusion—demic, cultural—being proposed. While this phenomenon has been exhaustively studied in Europe, with repeated attempts to model the speed of Neolithic diffusion based on radiocarbon dates, much less attention has been devoted to the dispersal towards the East, and in particular to South Asia. The Neolithic in the latter region at least partly derived from southwest Asia, given the presence of “founder crops” such as wheat and barley. The process of their eastward diffusion, however, may have been significantly different to the westward dispersal, which was mainly due to demic diffusion, as local domesticates were already available and farming was already practiced in parts of South Asia. Here, we use radiocarbon dates specifically related to the spread of the southwest Asian Neolithic crops to model the speed of dispersal of this agricultural package towards South Asia. To assess potential geographical and environmental effects on the dispersal, we simulate different speeds depending on the biomes being crossed, employing a genetic algorithm to search for the values that most closely approach the radiocarbon dates. We find that the most important barrier to be crossed were the Zagros mountains, where the speed was lowest, possibly due to topography and climate. A large portion of the study area is dominated by deserts and shrublands, where the speed of advance, albeit closer to the range expected for demic diffusion, was lower than observed in Europe, which can also potentially be attributed to environmental constraints in the adaptation of the crops. Finally, a notable acceleration begins in the Indus valley, exceeding the range of demic diffusion in the tropical and subtropical environments east of the Indus. We propose that the latter is due to the rapid diffusion among populations already familiar with plant cultivation.

Published: July 2022

Objectives

To evaluate the prognostic value of the coefficient of variance of axial light loss of monocytes (cv-ALL of monocytes) for adverse clinical outcomes in patients suspected of infection in the emergency department (ED).

Methods

We performed an observational, retrospective monocenter study including all medical patients ≥18 years admitted to the ED between September 2016 and June 2019 with suspected infection. Adverse clinical outcomes included 30-day mortality and ICU/MCU admission <3 days after presentation. We determined the additional value of monocyte cv-ALL and compared to frequently used clinical prediction scores (SIRS, qSOFA, MEWS). Next, we developed a clinical model with routinely available parameters at the ED, including cv-ALL of monocytes.

Results

A total of 3526 of patients were included. The OR for cv-ALL of monocytes alone was 2.21 (1.98–2.47) for 30-day mortality and 2.07 (1.86–2.29) for ICU/MCU admission <3 days after ED presentation. When cv-ALL of monocytes was combined with a clinical score, the prognostic accuracy increased significantly for all tested scores (SIRS, qSOFA, MEWS). The maximum AUC for a model with routinely available parameters at the ED was 0.81 to predict 30-day mortality and 0.81 for ICU/MCU admission.

Conclusions

Cv-ALL of monocytes is a readily available biomarker that is useful as prognostic marker to predict 30-day mortality. Furthermore, it can be used to improve routine prediction of adverse clinical outcomes at the ED.

Clinical, radiological and pathological characteristics of moderate to fulminant psittacosis pneumonia
Authors: Li Xiaoying , Xiao Tao , Hu Pengzhi , Yan Kun , Wu Jiongxing , Tu Xinya , Tang Yishu , Xia Hong
Published: July 2022

Background

Psittacosis pneumonia is a community-acquired pneumonia caused by Chlamydia psittaci. It is usually under-diagnosed due to its atypical clinical presentation and lack of routine laboratory tests.

Methods

To better understand the clinical features, 52 patients diagnosed with psittacosis pneumonia by metagenomic next-generation sequencing (mNGS) were enrolled in this study. The clinical, radiological and pathological characteristics were retrospectively analyzed.

Results

The onset of psittacosis pneumonia in this study occurred all year round, with a peak from December to January. Most of the patients were 51–80 years old. About 65.38% of patients had a history of exposure to poultry or parrots. Abnormalities of multiple clinical signals were detected in these patients. Elevated levels of neutrophil ratio, C-reactive protein, erythrocyte sedimentation rate, and procalcitonin were detected in most patients. Radiological evidence revealed air-space consolidation or ground-glass opacities in lungs of all patients, which is the typical feature of psittacosis pneumonia. In addition, hyperemia, swelling of bronchial mucosa, and bronchial patency were detected by bronchoscopy in all patients, and bronchial sub-mucosal edema, inflammatory cells infiltration and alveolar epithelial hyperplasia were identified in the bronchial mucosa and alveolar tissue. Beta-lactam antibiotics were administered for empirical treatment before mNGS in 17 patients but showed no improvement. The treatment was switched to doxycycline or moxifloxacin immediately since psittacosis pneumonia were suspected and confirmed by mNGS detection (within 48 hours). After receiving adjustment of treatment, 94.23% (49/52) of patients were cured successfully.

Conclusions

In conclusion, mNGS may be a promising approach for clinical diagnosis of psittacosis. For patients with a history of exposure to birds, hyperpyrexia, nonproductive cough, multiple elevated inflammatory markers, and air-space consolidation in lung, psittacosis pneumonia should be considered, especially when beta-lactam antibiotics showed limited efficacy.

Published: July 2022

Plant leaf area (LA) is a key metric in plant monitoring programs. Machine learning methods were used in this study to estimate the LA of four plum genotypes, including three greengage genotypes (Prunus domestica[subsp.italicavar.claudiana.]) and a single myrobalan plum (prunus ceracifera), using leaf length (L) and width (W) values. To develop reliable models, 5548 leaves were subjected to experiments in two different years, 2019 and 2021. Image processing technique was used to extract dimensional leaf features, which were then fed into Linear Multivariate Regression (LMR), Support Vector Regression (SVR), Artificial Neural Networks (ANN), and the Adaptive Neuro-Fuzzy Inference System (ANFIS). Model evaluation on 2019 data revealed that the LMR structure LA = 0.007+0.687 L×W was the most accurate among the various LMR structures, with R2= 0.9955 and Root Mean Squared Error (RMSE) = 0.404. In this case, the linear kernel-based SVR yielded an R2of 0.9955 and an RMSE of 0.4871. The ANN (R2= 0.9969; RMSE = 0.3420) and ANFIS (R2= 0.9971; RMSE = 0.3240) models demonstrated greater accuracy than the LMR and SVR models. Evaluating the models mentioned above on data from various genotypes in 2021 proved their applicability for estimating LA with high accuracy in subsequent years. In another research segment, LA prediction models were developed using data from 2021, and evaluations demonstrated the superior performance of ANN and ANFIS compared to LMR and SVR models. ANFIS, ANN, LMR, and SVR exhibited R2values of 0.9971, 0.9969, 0.9950, and 0.9948, respectively. It was concluded that by combining image analysis and modeling through ANFIS, a highly accurate smart non-destructive LA measurement system could be developed.
Effects of return flows on stream water quality and availability in the Upper Colorado, Delaware, and Illinois River Basins
Authors: Ator Scott W. , Miller Olivia L. , Saad David A.
Published: July 2022

Understanding effects of human water use and subsequent return flows on the availability and suitability of water for downstream uses is critical to efficient and effective watershed management. We compared spatially detailed estimates of stream chemistry within three watersheds in diverse settings to available standards to isolate effects of wastewater and irrigation return flows on the suitability of downstream waters for maintaining healthy aquatic ecosystems and for selected human uses. Mean-annual flow-weighted total and source-specific concentrations of nitrogen and phosphorus in individual stream reaches within the Upper Colorado, Delaware, and Illinois River Basins and of total dissolved solids within stream reaches of the Upper Colorado River Basin were estimated from previously calibrated regional watershed models. Estimated concentrations of both nitrogen and phosphorus in most stream reaches in all three watersheds (at least 78%, by length) exceed recommended standards for the protection of aquatic ecosystems, although concentrations in relatively few streams exceed such standards due to contributions from wastewater return flows, alone. Consequently, efforts to reduce wastewater nutrient effluent may provide important local downstream benefits but would likely have minimal impact on regional ecological conditions. Similarly, estimated mean-annual flow-weighted total dissolved solids concentrations in the Upper Colorado River Basin exceed standards for agricultural water use and (or) the secondary maximum contaminant level (SMCL) for drinking water in 52% of streams (by length), but rarely due to effects of irrigation return flows, alone. Dissolved solids in most tributaries of the Upper Colorado River are attributable primarily to natural sources.

Comunicação partilhada do alerta de cheia na bacia hidrográfica do rio Vez
Authors: Gonçalves Maria da Glória Salgado
Published: July 2022

Os telemóveis são meios de comunicação para trocar informações entre os utilizadores através de chamadas, serviço de mensagens curtas e acesso à Internet, onde se incluem as redes sociais. As formas de comunicação fornecem dados das coordenadas, essenciais para prestar auxílio quando necessário. Os meios de comunicação social acompanham as sociedades, publicando as notícias sobre as cheias, assim como as respetivas consequências. Como as notícias existem impressas, maioritariamente nos acervos das bibliotecas, desenvolveu-se o projeto eBDRegister para registo de eventos em base de dados. Após identificar os cidadãos localizados nos centroides das cheias, propomo-nos resolver um problema que é saber como e quem pode e deve comunicar o alerta do perigo a esses cidadãos. Propõe-se um serviço de comunicação partilhado por quem possui os dados dos cidadãos. Utilizam-se os registos do histórico das notícias na bacia hidrográfica do rio Vez, desde 1900 até 2015, para delimitar o raio máximo dos centroides das cheias, com 635,9 m, e o raio de 90% dos dados com 290,2 m. A validade das fontes da imprensa periódica foi testada pelo modelo Logit e pelo percentil noventa. O estudo dos centroides e respetivos raios de distância ao rio mais próximo serve de prova para a aplicação do sistema de comunicação partilhado entre os organismos da imprensa periódica, as seguradoras e a Autoridade Tributária e Aduaneira e os cidadãos identificados.

Published: July 2022

Este artículo ambiciona contribuir al ensanchamiento de una de las líneas de investigación más sólidamente afianzadas en la historiografía española de los últimos decenios: la relacionada con la evolución del socialismo español. Partiendo de un caso de estudio específico, correlacionado con la ciudad de Bilbao entre finales del siglo XIX y principios del siglo XX, se abordan las conexiones entre dos frentes temáticos que, sin embargo, no han sido objeto de una atención preferencial en las numerosas miradas desplegadas sobre el movimiento obrero organizado. De una parte, las dinámicas que se vislumbraron en la trayectoria electoral del socialismo a nivel local, conectadas con la movilización del voto y las técnicas y estrategias aplicadas por la formación política, tanto en lo relativo al fomento de su aprendizaje y libre ejercicio como en lo concerniente a su captación a nivel socioespacial, en el contexto de las elecciones municipales celebradas entre 1891 y 1905. De otra parte, los patrones de conducta que la organización asumió a la hora de desarrollar una acción política municipal imbuida de los principios de la implementada en Francia y coherente con los perfiles programáticos y discursivos definidos en las campañas electorales.

Characteristics of Education 4.0
Authors: Pinto Carlos Alberto Schettini , Reis Augusto da Cunha
Published: July 2022

Highlights: Education 4.0, prioritizes practical experimentation on the part of students, intensifies the understanding of the “maker culture”. Education 4.0 consists of an advanced theoretical-practical approach to management and teaching in formal education. We can see those features such as Digital Didactic Material, Hybrid Teaching, Digital Interactivity, Autonomous Learning and New Information and Communication Technologies were essential for education not to be stagnant in time x space during the COVID 19. Teachers need to innovate and renew their knowledge constantly. In the 4.0 environment, acting as guides, tutors, advisors, they need to be connected with the reality and the actuality of the facts, so that they can correctly lead their students in the construction of knowledge.
Goal: The present study aims to present, from the main characteristics of Education 4.0, its possibilities and applicability in times of pandemic.
Design / Methodology / Approach: As a subsidy, an exploratory study was carried out through bibliographic research in the main research bases in order to obtain updated knowledge on the theme of Education 4.0.
Results: The results denote the importance of the applicability of the main ideas of this form of education in the current and future moment, mainly because the current and future generations are very involved in the concepts of connectivity and hybrid learning.
Limitations of the Investigation: The limitations of this research reside in the fact that, as it is a new situation, which had to be adopted almost instantly, it needs to have a greater maturity and there is a need for further research and studies, mainly in the search for the best application of technologies in the educational field.
Practical implications: The practical implications highlight that the use of technologies in education is a reality in which teachers and students should increasingly perceive themselves as immersed and open to new educational possibilities.
Originality/Value: The originality lies in the fact that the various educational institutions, at different educational levels, had to adapt to a new reality imposed by the pandemic situation, where the need for the massive use of technology was fundamental for the minimum maintenance of the teaching-learning process. And this work sought to denote these characteristics.
Influence of Stress Concentration Factor due to Scallop Form on the Wrang Plate Stucture
Authors: Kusnadi Putri Riska Arum Dona , Yulianto Totok , Ariesta Rizky Chandra , Misbah Mohammad Nurul
Published: July 2022

The presence of opening in construction is unavoidable for the purpose of reducing stress. A small opening at the construction serves as access to continue the installed construction that runs through the web or girder. However, the presence of the hole also creates an unavoidable problem, the concentration of stress in the area around the hole that will gradually reduce the strength of the ship's construction. Stress concentration occurs due to changes in geometry, causing the flow of stress initially uniformly driven and following the existing geometry. This analysis aims to determine the value of stress concentration factors on the wrang plate due to variations in the shape of scallops. The research method is performed numerically using finite element analysis to find variations in the model with the lowest stress concentration factor. This variation consists of 3 different scallops models with 2 load, drag and press conditions. The values of stress concentration factors are grouped into 3 modes according to mechanical fractures in press loading conditions. Based on the analysis of panel models with compressed loads, it can be seen that model III has the smallest stress concentration factor value in case modes I and III but for mode II the value of the smallest stress concentration factor in model II.

Published: July 2022

The discussion of hydrodynamic forces becomes an important issue in determining the dynamic behaviour of the Submerged Floating Tunnel Bridge (SFTB) structure. As stated in the Morison Equation, the hydrodynamic forces are affected by the kinematics of water particles, but up to this date, there are only a few discussions for curved tube applications. This paper discusses the effect of curvature radius and depth level on hydrodynamic forces to get the correction factor for a straight tube. Tubes with variations in radius curvature (R/L) and diameter (D) were installed in a wave pool with a depth level (z/d). The hydrodynamic forces were detected by a load cell sensor placed on a pedestal at the end of the specimen. The data from the load cell was processed by the data acquisition system and displayed on the monitor screen, showing that the z/d ratio and the R/L ratio both affect the hydrodynamic forces. A larger z/d ratio (deeper) results in smaller hydrodynamic forces, while a smaller R/L ratio (more curved) results in smaller hydrodynamic forces. A correction factor (C) has been determined to calculate the hydrodynamic force on a curved tube based on the Morison equation.
Numerical Investigation of the Effect of Biodiesel-Biogas Percentage on Performance Characters and Dual Fuel Engine Emissions as Green Technology on Ship
Authors: Ariani Betty , Wahyudi Dedy
Published: July 2022

The discourse on the application of green technology in the maritime sector is an interesting agenda to implement. The development of the world of shipping transportation which continues to experience an increase in numbers and services creates new problems in terms of fuel supply and the resulting emissions. So that the development of innovation and technology for ship machinery should be directly related to fossil fuel substitution technology, operational efficiency technology, improving performance and reducing emissions from the engine itself to be achievements and targets. Good engine performance directly has an impact on increasing the operational efficiency of the ship and being a good carrying capacity in the environment with minimal emission levels. A dual-fuel engine is one of the engine system concepts that has several advantages, such as simple and relatively easy modifications and the use of natural gas which tends to be cleaner. Biodiesel and biogas are examples of alternative fuels that are expected to be promising solutions for marine engineering. This research uses a numerical study on the application of dual fuel engines, the percentage of biodiesel-biogas is carried out with variations of 50:50 and 25:75, at a constant engine speed of 2200 RPM. Simulations were carried out to see the results of how the engine performance, cylinder pressure, heat release rate and HC and NOx emissions were at a constant speed variation of the fuel percentage test NOx emission decreased at a higher biogas percentage, for UHC it increased at a higher biogas percentage, it is possible to add oxygen intake through a turbocharger or supercharger as an auxiliary equipment.

Objetivos

El estudio y abordaje de un caso clínico de una paciente con elevaciones de potasio en las sucesivas revisiones sin justificación clínica.

Caso clínico

Presentamos un caso clínico de una paciente con una elevación de potasio en las sucesivas analíticas realizadas por su médico de Atención Primaria, sin justificación clínica. La paciente es derivada a Nefrología, con potasemias mantenidas de 5,3–5,9 mmol/L en suero sin más datos de interés, tratada con dieta baja en potasio sin éxito. En el estudio completo no se encuentra ninguna causa orgánica que justifique la elevación.

Conclusiones

Ante resultados discordantes entre las cifras de potasio y el motivo de consulta, y tras haber descartado otras causas preanalíticas o patológicas, se propone que la posible causa sea una pseudohiperpotasemia familiar. Se realiza un protocolo de incubación de la muestra a diferentes tiempos y temperaturas para demostrar su influencia en los niveles de potasio en sangre, por lo que se concluye el diagnóstico más probable de pseudohiperpotasemia familiar. Finalmente, la paciente es dada de alta por parte de Nefrología, con lo que puede retomar una dieta normal.

Objectives

Patient-based real-time quality control (PBRTQC) has gained increasing attention in the field of laboratory quality management in recent years. However, PBRTQC has not been reported for use in molecular diagnostics. This study introduces PBRTQC to quantitative hepatitis B virus (HBV) DNA test using moving rate (MR) of positive and negative patient results.

Methods

In contrast to the MR protocols described in other literature, MR protocol for HBV-DNA test has an additional logarithmic transformation and binary conversion steps before using a common statistical process control algorithm, such as the MR. We used all patient test results of HBV-DNA assay from August 2018 to August 2021 at the Second Affiliated Hospital of Guangzhou University of Chinese Medicine, for parameters setting, optimization, and performance validation. The false rejection rate, error detection curves and validation charts were used to assess the MR protocols.

Results

The false rejection rates of two MR protocols were both <0.7%. The optimal block sizes for positive and negative errors in each cut-off value were not the same, so we first proposed a combined protocol that used different block size to detect negative and positive errors. It turned out that the combined protocols outperformed the simple protocols for each cut-off value, especially detecting positive errors.

Conclusions

The performances of MR protocols using positive or negative patient results to detect constant errors of HBV-DNA test could meet laboratory requirements. Therefore, we have provided an effective alternative tool for internal quality control in the field of molecular diagnostics.
A new sonographic marker in the diagnosis of prenatal bilateral renal agenesis, segmental anterior deviation of the aorta

Objectives

Bilateral renal agenesis is a rare congenital anomaly that is associated with high neonatal mortality. Bilateral renal agenesis is most often present with anhydramniosis in the mid-trimester.

Case presentation

We report a case of bilateral renal agenesis diagnosed prenatally. We presented the ultrasound and pathology images of this fetus with a new sonographic sign, segmental anterior deviation in the abdominal aorta.

Conclusions

To our knowledge, this is the first reported case of a fetus with a segmental aortic anterior deviation.
Scripting Swiss smiles: a sociolinguistic analysis of affective-discursive practices in a Swiss call centre
Authors: Flubacher Mi-Cha
Published: July 2022

Revisiting data from a sociolinguistic ethnography of an in-bound Swiss call centre (2010–2011), I will show how the scripted smile of agents is fused strategically with the use of the dialect in order to produce ‘affective-discursive practices’ that aim for a projection of quality of service. These practices include ‘scripted affective efficiency’ and the ‘stylization of Swiss authenticity’. Inherently embedded in and emblematic of the political economy, these particular affective-discursive practices are conducive to the company’s branding strategies of authenticity, directly linked to market distinction and profit generation. From today’s standpoint, i.e. 10 years later, transformations in ICT (Information and Communications Technology) have displayed the limits of these affective practices and their underlying discourses and ideologies in the face of cost-benefit analyses when the number of incoming calls dwindled due to the development of smartphones. This paper will discuss affective-discursive practices from a political-economic and critical sociolinguistic perspective.
The pedagogy of love: a register of precarised English teachers in Chile
Authors: Anabalon Schaaf Rommy
Published: July 2022

In this contribution, I will look at the imbrication of language, labour and affective capitalism in the exemplary context of a Chilean private university, as part of a larger sociolinguistic ethnography project that seeks to examine processes of precarisation in university teachers. I argue that the affective-discursive practices used by three English Language teachers, which they called the pedagogy of love, constitute a register. This register is one of the many available to women and men, which they can manage, negotiate, manipulate and capitalise on. I show in this article the way teachers enact, align with and detach from the register to make sense of their professional identities and navigate a precarious higher education market, and how the university benefits from it to regulate teachers’ labour and students’ expectations and eventually, obtain financial stability.
Empowerment narratives and sticky affects: the workings of affective capitalism in Philippine call centers
Authors: Salonga Aileen Olimba
Published: July 2022

In contemporary work arrangements that are premised on the exchange of information, communication, and services, one dominant instrumentality of affective capitalism is the practice of emotional labor. In this paper, I turn my attention to the promise of empowerment in the workplace and propose that it is another instrumentality of affective capitalism. Specifically, I examine the ways through which positive feelings are evoked and maintained in the Philippine call center industry through the circulation of empowerment narratives that are of particular significance to its Filipino workers. Using Wetherell’s notion of affective practice and Ahmed’s notion of the stickiness of emotion, I examine the affective-discursive dimensions of the empowerment narratives, trace their repeated telling, and surface the other narratives upon which they draw to show how particular affects become sticky, that is, how they gain recognition and resonance, and are felt and taken up by the same bodies that circulate them. In making explicit the relationship between the empowerment narratives and their sticky affects, I demonstrate that the promise of empowerment in the call centers is as much a discursive practice as it is an affective one. Thus, to make sense of the workings of affective capitalism in the new work order, it is crucial to interrogate not only the affective dispositions that workers are made to occupy in the workplace, but also dominant workplace discourses that are, in fact, designed to evoke, circulate, and maintain the desired affects.

Transposable elements are mobile sequences that can move and insert themselves into chromosomes, activating under internal or external stimuli, giving the organism the ability to adapt to the environment. Annotating transposable elements in genomic data is currently considered a crucial task to understand key aspects of organisms such as phenotype variability, species evolution, and genome size, among others. Because of the way they replicate, LTR retrotransposons are the most common transposable elements in plants, accounting in some cases for up to 80% of all DNA information. To annotate these elements, a reference library is usually created, a curation process is performed, eliminating TE fragments and false positives and then annotated in the genome using the homology method. However, the curation process can take weeks, requires extensive manual work and the execution of multiple time-consuming bioinformatics software. Here, we propose a machine learning-based approach to perform this process automatically on plant genomes, obtaining up to 91.18% F1-score. This approach was tested with four plant species, obtaining up to 93.6% F1-score (Oryza granulata) in only 22.61 s, where bioinformatics methods took approximately 6 h. This acceleration demonstrates that the ML-based approach is efficient and could be used in massive sequencing projects.
