Edge-assisted Object Segmentation Using Multimodal Feature Aggregation and Learning
Authors: Li Jianbo , Yuan Genji , Yang Zheng
Published: August 2023

Object segmentation aims to perfectly identify objects embedded in the surrounding environment and has a wide range of applications. Most previous methods of object segmentation only use RGB images and ignore geometric information from disparity images. Making full use of heterogeneous data from different devices has proved to be a very effective strategy for improving segmentation performance. The key challenge of the multimodal fusion-based object segmentation task lies in the learning, transformation, and fusion of multimodal information. In this article, we focus on the transformation of disparity images and the fusion of multimodal features. We develop a multimodal fusion object segmentation framework, termed the Hybrid Fusion Segmentation Network (HFSNet). Specifically, HFSNet contains three key components, i.e., disparity convolutional sparse coding (DCSC), asymmetric dense projection feature aggregation (ADPFA), and multimodal feature fusion (MFF). The DCSC is designed based on convolutional sparse coding. It not only has better interpretability but also preserves the key geometric information of the object. ADPFA is designed to enhance texture and geometric information to fully exploit nonadjacent features. MFF is used to perform multimodal feature fusion. Extensive experiments show that our HFSNet outperforms existing state-of-the-art models on two challenging datasets.
Functional Trait Variation Along Animal Invasion Pathways
Authors: Chown Steven L. , McGeoch Melodie A.
Published: August 2023

Functional trait–based mediation of animal invasions is only now developing, yet it is already showing as much promise as the approach has for plant invasion biology. Here, we provide a theory-founded examination of functional trait–based ecology with respect to animal invasions, together with a review of the empirical research. Recent developments in the scaling of traits to ecosystems, along with the frameworks for invasion ecology, provide a powerful foundation for investigations. Despite growing empirical research in this field, interspecific comparisons incorporating comparative phylogenetic approaches remain uncommon, and those examining assemblages are even more so. Despite the importance of time since introduction, it is rarely included in studies. Broad environmental tolerances, life history traits associated with fast growth or greater reproduction, and in some cases, greater phenotypic plasticity of traits, mediate the success of animal alien species at various stages of invasion, although introduction effort remains one of the most important factors affecting success.
Multiscale Time-Frequency Sparse Transformer Based on Partly Interpretable Method for Bearing Fault Diagnosis

Published: August 2023

Transformer model is being gradually studied and applied in bearing fault diagnosis tasks, which can overcome the feature extraction defects caused by long-term dependencies in convolution neural network (CNN) and recurrent neural network (RNN). To optimize the structure of existing transformer-like methods and improve the diagnostic accuracy, we proposed a novel method based on the multiscale time-frequency sparse transformer (MTFST) in this paper. First, a novel tokenizer based on shot-time Fourier transform (STFT) is designed, which processes the 1D format raw signals into 2D format discrete time-frequency sequences in the embedding space. Second, a sparse self-attention mechanism is designed to eliminate the feature mapping defect in naive self-attention mechanism. Then, the novel encoder-decoder structure is presented, the multiple encoders are employed to extract the hidden feature of different time-frequency sequences obtained by STFT with different window widths, and the decoder is used to remap the deep information and connect to the classifier for discriminating fault types. The proposed method is tested in the XJTU-SY bearing dataset and self-made experiment rig dataset, and the following work is conducted. The influences of hyperparameters on diagnosis accuracy and number of parameters are analysed in detail. The weights of the attention mechanism (AM) are visualized and analysed to study the interpretability, which explains the partly working pattern of the network. In the comparison test with other existing CNN, RNN, and transformer models, the diagnosis accuracy of different methods is statistically analysed, feature vectors are presented via the t-distributed stochastic neighbor embedding (t-SNE) method, and the proposed MTFST obtains the best accuracy and feature distribution form. The results demonstrate the effectiveness and superiority of the proposed method in bearing fault diagnosis.
Adaptive Terminal Sliding Mode Fault-Tolerant Control of Spacecraft Based on the Left Attitude Error Function of SO(3)
Authors: Zheng Zhongzhong , Shang Wei , Liu Zhou , Guo Yongda
Published: August 2023

For the problem of spacecraft attitude actuator failure, an adaptive terminal sliding mode fault-tolerant controller (ATSMFTC) based on the differential manifold SO(3) modelling is designed in this paper. First, SO(3) is used to provide a global and unique description of the spacecraft attitude dynamic model. This modelling method not only avoids the problems of singularity and unwinding that exist in traditional modelling methods but also the SO(3) modelling has a simple formulation of the dynamic equations. Then a left attitude error descriptor function is constructed on SO(3) to design an ATSMFTC. This controller is capable of fast and accurate tracking of the time-varying desired attitude. At the same time, it can react quickly to maintain system stability in case of spacecraft attitude actuator failure. The controller designed based on the left attitude error description system of SO(3) has the features of small computational effort and simple design process. Finally, the numerical simulation of the attitude tracking error verifies the feasibility and high efficiency of the controller designed in this paper.

Introduction. Balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) is a useful therapeutic procedure that provides promising results in patients with surgically altered anatomy. However, biliary cannulation in BE-ERCP remains challenging. Therefore, in patients with Roux-en-Y gastrectomy, this study aimed to evaluate a BE-ERCP cannulation strategy that includes the newly developed alpha-retroflex scope position. Methods. This was a retrospective review of 52 patients with Roux-en-Y gastrectomy who underwent BE-ERCP at two centers between April 2017 and December 2022. In these patients, three types of scope position had been used for biliary cannulation: straight (S-position), J-retroflex (J-position), and alpha-retroflex (A-position). First, the S-position was used for biliary cannulation. Then, if biliary cannulation was difficult with this position, the J-position was used, followed by the A-position, if necessary. Results. The biliary cannulation success rate was 96.6% (50/52). The S-, J-, and A-positions achieved successful biliary cannulation in 24 (48%), 14 (28%), and 12 patients (24%), respectively. No adverse events, including post-ERCP pancreatitis and perforation, occurred. Conclusion. This was the first study of a cannulation strategy that included the A-position in addition to the S- and J-positions. The study showed that the A-position is feasible and safe in BE-ERCP in patients with Roux-en-Y gastrectomy.
Tamil OCR Conversion from Digital Writing Pad Recognition Accuracy Improves through Modified Deep Learning Architectures
Authors: Jayanthi V. , Thenmalar S.
Published: August 2023

Digital handwritten recognition is an emerging field in optical character recognition (OCR). A digital writing pad replaces manual writing. In digital writing, the alphabet changes in font and shape. During OCR recognition, covert text file errors occur due to digital pen pressure and digital pen position on the digital pad by the writer. The shape changes in the alphabet lead to an error during the conversion of OCR to text. The above problem arises in Tamil, Chinese, Arabic, and Telugu, where the alphabet consists of bends, curves, and rings. OCR‐to‐text conversion for the Tamil language has more word errors due to angles and curves in the alphabet, which need to be converted accurately. This paper proposes ResNet two‐stage bottleneck architecture (RTSBA) for Tamil language‐based text recognition written on a digital writing pad. In the proposed RTSBA, two separate stages of neural networks reduce the complexity of the Tamil alphabet recognition problem. In the initial stage, the number of inputs and variables is reduced. In the final stage, time and computation complexity are reduced. The proposed algorithm has been compared with traditional algorithms such as long short‐term memory, Inception‐v3, recurrent neural networks, convolutional neural networks, and a two‐channel and two‐stream transformer. Proposed methods, such as RTSBA applied in the digital writing pad‐handwritten and HP lab datasets, achieved an accuracy of 98.7% and 97.1%, respectively.

Published: August 2023

Increasing risks of infections with foodborne pathogens may occur as a result of poor food handling practices. The present cross-sectional study employed a mixed-methods approach to determine the factors associated with foodborne pathogens among food handlers working in the food establishments in Thika, Kiambu County, Kenya. Random sampling was used to enroll respondents in the survey. A single stool specimen was collected from each study participant. Laboratory analysis of the specimen was done to test the selected foodborne pathogens. Overall, 44 out of the 285 food handlers who took part in the study had at least one food-transmitted pathogen, putting the prevalence of foodborne infections among the food handlers at 15.4% (95% confidence interval (CI) 11.7%–20.1%). The findings from multivariate logistic regression indicated the following protective factors for foodborne pathogens among the studied food handlers: being female (adjusted odds ratio (AOR) 0.098 (95% CI 0.0304–0.315,

p
<
0.001

)); having a valid medical examination certificate (AOR 0.141 (95% CI 0.141–1. 0.439,

p
=
0.001

)); not boiling or treating water before serving the water to customers was a risk factor for having infections with foodborne pathogens (AOR 3.043 (95% CI 1.2225–7.577,

p
=
0.017

)). The presence of foodborne pathogens among the food handlers in the study area potentially highlights the need to address the spread and transmission of foodborne infections in the study area. There is a need to institute appropriate control measures, including regular screening of food handlers for foodborne illnesses in addition to training them on safe food handling practices, hand hygiene practices, and regular monitoring of the food handling practices.

Abstract
Intraductal papillary mucinous neoplasms (IPMN) of the pancreas are bona fide precursor lesions of pancreatic ductal adenocarcinoma (PDAC). The most common subtype of IPMNs harbors a gastric foveolar-type epithelium, and these low-grade mucinous neoplasms are harbingers of IPMNs with high-grade dysplasia and cancer. The molecular underpinning of gastric differentiation in IPMNs is unknown, although identifying drivers of this indolent phenotype might enable opportunities for intercepting progression to high-grade IPMN and cancer. We conducted spatial transcriptomics on a cohort of IPMNs, followed by orthogonal and cross-species validation studies, which established the transcription factor NKX6-2 as a key determinant of gastric cell identity in low-grade IPMNs. Loss of NKX6-2 expression is a consistent feature of IPMN progression, while reexpression of Nkx6-2 in murine IPMN lines recapitulates the aforementioned gastric transcriptional program and glandular morphology. Our study identifies NKX6-2 as a previously unknown transcription factor driving indolent gastric differentiation in IPMN pathogenesis.
Significance:
Identification of the molecular features driving IPMN development and differentiation is critical to prevent cancer progression and enhance risk stratification. We used spatial profiling to characterize the epithelium and microenvironment of IPMN, which revealed a previously unknown link between NKX6-2 and gastric differentiation, the latter associated with indolent biological potential.

O nome da rua, da avenida e da praça : a mudança de denominação dos logradouros do Centro de Fortaleza (1810 – 1933)
Authors: Silva Gleilson Angelo da
Published: August 2023

Os logradouros fazem parte da morfologia urbana e são elementos fundamentais para o fluxo intenso, sobretudo nas metrópoles e grandes cidades. Fortaleza se insere neste contexto a partir do bairro Centro e seu conjunto de logradouros refletindo a Geografia e a História da capital que passou por profundas transformações que podem ser observadas até hoje tanto pelo seu traçado quanto pelos nomes de ruas, avenidas, becos, travessas e praças. Partindo de 1810 quando houve o primeiro levantamento de ruas até a década de 1930 muitas foram as transformações que os logradouros passaram tanto em sua forma física (padronização) quanto em sua parte simbólica (antigas denominações que expressavam hábitos e costumes de uma época) resultando numa miscelânea toponímica. O estudo do espaço urbano e como ele foi modificado, juntamente com a toponímia, enfatizou alguns processos que fizeram da vila de Fortaleza a grande metrópole ainda no século XX e estes vestígios estão presentes nas nomenclaturas que ainda permanecem. A partir de leis, códigos de posturas, atas da câmara municipal, crônicas e livros de memorialistas, dentre outros foi possível reaver nomes que foram substituídos e, aliado a um método de regressão e progressão, viabilizou-se a criação de quadros a partir de materiais cartográficos auxiliando na compreensão dessas alterações até os dias de hoje. Os nomes dos logradouros são o reflexo de todos os processos que estão aliados aos âmbitos da política, da economia, da geografia, da história, da memória, do social e cultural.
Utilização de diferentes derivações do modelo Shalstab como ferramenta de auxílio ao monitoramento da suscetibilidade de movimento de massa em bacias hidrográficas com presença de ativos de transmissão de energia

Published: August 2023

O objetivo deste trabalho é avaliar a utilização do modelo Shalstab para realizar um diagnóstico da suscetibilidade a movimentos de massa considerando três diferentes abordagens: i) Shalstab em nível de risco (resultado da razão log(q/t)) pixel-a-pixel; ii) Shalstab em nível de risco generalizado por bacias e; iii) Chuva crítica diária necessária para deflagração de ruptura (Shalstab em termos de “q” - precipitação). A área de estudo se refere a bacias hidrográficas que intersectam uma linha de transmissão situada na Serra do Mar Paranaense e para a parametrização dos valores geotécnicos utilizados na modelagem adotou-se uma abordagem espacializada que leva em conta a variabilidade da tipologia geológica da área. As cicatrizes de movimento de massa utilizadas para validação dos resultados indicam que ambas as abordagens do modelo em nível de risco (pixel-a-pixel e generalizado por bacias) foram capazes de identificar com um bom nível de acerto as áreas mais suscetíveis. Em relação aos limiares de chuva crítica para provocar rupturas na área de estudo, precipitações acima de 100mm/dia são perigosas para muitos locais. Esse valor de precipitação é bastante comum na região, o que indica necessidade de atenção, sobretudo em momentos com configurações pluviométricas próximas a esse limiar.
Proposta metodológica para identificar o uso possível das terras em áreas rurais degradadas por processos erosivos
Authors: Zanatta Felipe Augusto Scudeller , Lupinacci Cenira Maria
Published: August 2023

A perda e o desperdício de recursos naturais é um paradigma da sociedade atual, sobretudo nas áreas agrícolas, onde o uso indevido das terras acaba por intensificar a erosão do solo. Nesse sentido, esta pesquisa apresenta uma proposta metodológica para identificar o uso agrícola adequado às características dos terrenos, assim como aqueles setores que precisam ser recuperados e protegidos, para assegurar a estabilidade dos solos e dos processos ecológicos.  Para tanto, selecionou-se como área modelo um conjunto de bacias localizadas no município de Marabá Paulista (SP), totalmente utilizadas para agropecuária, onde se encontram centenas de formas erosivas. Nessa área, foram mapeadas características físicas, do uso e cobertura da terra, das feições geomorfológicas em perspectiva histórica e áreas legalmente protegidas. Os dados dos mapeamentos foram analisados por meio das metodologias da Geoecologia da Paisagem, da cartografia geomorfológica retrospectiva e do Sistema de Capacidade de Uso das Terras. A partir da avaliaçãodestas metodologias, elaboraram-seduas árvores de decisão, em que a combinação dos elementos indica o uso possível dos terrenos, norteando dois mapeamentos: ideal e viável, este com menor número de variáveis a serem utilizadas. Como resultado, os mapeamentos permitiram indicar padrões futuros de uso da terra que respeitam as limitações físicas e o histórico de uso dos terrenos. Buscou-se ainda incorporar a noção de vizinhança a estes padrões, compreendendo que as feições erosivas tendem a se expandir para o entorno.
Avaliação conceitual e síntese de ferramentas metodológicas na determinação da sensibilidade à erosão e inundação costeira
Authors: Machado Giseli Modolo Vieira , Albino Jacqueline
Published: August 2023

A identificação de seções da costa sensíveis ao aumento do nível do mar é necessária para uma gestão mais eficaz da zona costeira, a fim de aumentar a resiliência e ajudar a reduzir os impactos. Porém, a diversidade de sistemas costeiros e as diferenças regionais de aumento relativo do nível do mar fazem com que a resposta para os fenômenos de erosão e inundação costeira não sejam uniformes no globo. Por isto, a avaliação da sensibilidade costeira assume o ponto de partida para a avaliação da vulnerabilidade. No entanto, desafios metodológicos são decorrentes desta difícil tarefa de compreender e avaliar a dinâmica dos ecossistemas costeiros. Além disso, inconsistências conceituais em torno do termo vulnerabilidade podem gerar incompreensões metodológicas e o emprego distraído de certas variáveis pode comprometer os índices de sensibilidade costeira. Este artigo se propõe a contribuir com uma base conceitual e metodológica destinada aos pesquisadores que irão iniciar na jornada de mapeamento da sensibilidade costeira; apresentando uma síntese das principais ferramentas de avaliação da vulnerabilidade e discutindo o significado das variáveis físicas mais utilizadas para a classificação da sensibilidade costeira. Independente da abordagem metodológica adotada, o pesquisador deve ter ciência das limitações da ferramenta, onde a escolha das variáveis é também uma questão de escala, pois o detalhamento das feições morfológicas e dos processos se faz necessário em escala local.
Fragmentação espacial de bosques de mangue em um sistema estuarino semiárido do Nordeste do Brasil

Published: August 2023

Considerando a ampla ocorrência de manguezais em estuários hipersalinos do litoral semiárido do Brasil, cria-se uma demanda por estudos que indiquem como esse ecossistema tem se distribuído nas paisagens fluviomarinhas. Essa pesquisa buscou analisar a fragmentação espacial da vegetação de mangue que ocorre na zona estuarina do Rio Piranhas-Açu (RN), a partir de três etapas: 1) Levantamento bibliográfico de documentos nacionais e internacionais para subsidiar o trabalho; 2) Mapeamento dessa vegetação nos anos de 2008 e 2021; e 3) Aplicação de métricas de paisagem de área, forma e proximidade, utilizando um Sistema de Informação Geográfica. Em se tratando dos resultados, esses indicaram uma redução de 329,8 ha de mangue e um aumento de 230 manchas contíguas destes bosques, em pouco mais de uma década. Os dosséis com área inferior a 20 ha representaram mais de 88% da ocupação em ambos os anos. Esse valor reverberou na resposta dos parâmetros de forma, o qual indicou que mais de 50% dos mesmos encontraram-se irregulares, apresentando uma influência importante da relação entre o perímetro e a área. Com a formação de bosques adjacentes, a métrica do vizinho mais próximo informou que a distância euclidiana menor igual a 30 m representou mais de 75% dos padrões espaciais. Portanto, a perda de ocupação de mangue e a sua fragmentação podem vir a progredir em um futuro próximo, caso não sejam realizadas ações de monitoramento deste processo, assim como recuperação de áreas que estejam degradadas.

Fatty acids are considered metabolic intermediaries, although new facts indicate they also work as signaling molecules with different roles in the immune response. Based on that, in this study, we investigated the anti-inflammatory effects of n-3 polyunsaturated fatty acids (PUFAs) as eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and α-linolenic acid (LNA) in ex vivo bovine endometrial explants. For this, two groups were formed: (1) LPS-challenged and (2) control, both to evaluate the accumulation of proinflammatory cytokines as interleukin 1β (IL1B) and interleukin 6 (IL6). To develop the study, bovine female reproductive tracts from non-pregnant Angus heifers without evidence of reproductive diseases were selected. Endometrial explants were processed and treated for 24 h with EPA, DHA, and LNA in five different concentrations (0μM, 50μM, 100 μM, 200μM and 400 μM) and then, challenged with LPS for 24 h. Supernatants were collected to evaluate the concentration of IL1B and IL6 by ELISA. Explants treated with EPA from control groups reduced the concentrations of ILB (200μM) and IL6 (400 μM), and IL6 (50 μM; 100 μM) from the LPS-challenged group. DHA decreased the accumulation of IL1B and IL6 at 200 μM on explants from the LPS-challenged group, and 200 μM reduced IL6 from the control group. In contrast, explants treated with LNA only reduced the accumulation of IL1B to 400μM (from both groups). In conclusion, the EPA acid is the best anti-inflammatory option to decrease the concentration of both pro-inflammatory cytokines (IL1B and IL6) from LPS-challenged and control groups in bovine endometrial explants; while LNA evidence to be the last option to promote an anti-inflammatory response.

Reformulaciones teóricas y metodológicas en América Latina en torno a Archivos de escritores y artistas”, radicado en la Universidad de La Plata, Argentina. El hilo conductor que articula los tres apartados es la noción de “intervención”, entendida como conjunto de acciones que involucran a lxs investigadorxs en las distintas etapas de un proceso de archivación y que responde a dos necesidades: resguardar los documentos y hacer visibles (y legibles) ciertas zonas de los archivos de escritores. La asignación de un marco teórico metodológico a una edición crítico-genética (archivo Bellatin), el pasaje de un documento del ámbito privado al público (archivo Cortázar) y la puesta en relación entre archivo e imágenes de escritor (archivo Canton) constituyen una muestra sucinta de las intervenciones realizadas como parte de un trabajo a largo plazo, individual y colectivo, que reflexiona permanentemente desde la especificidad de los archivos latinoamericanos.
El libro de artista de Raquel "Kuki" Giubileo: una obra con los otros papeles
Authors: Fayolle Lucía
Published: August 2023

Desde el proceso de formación de los Estados-Nación, se necesitó construir una ficción de desierto (Rodríguez, 2010) para los territorios alejados de los grandes centros urbanos. Esta requirió tanto de una literatura como de un archivo que la acompañe, sostenga y justifique. En este artículo nos preguntamos ¿Qué hay allí donde se ha ficcionalizado vacío, desierto, barbarie? ¿Qué es lo que detuvo la destrucción, la desaparición de los papeles que hoy nos reencontramos desde el arte y la literatura? (Didi-Huberman, 2021) ¿Qué hacen las artistas del noroeste de la provincia de Buenos Aires con los papeles que quedaron por fuera del archivo oficial? ¿Qué versiones de la historia cuentan sus obras? ¿Cómo intervienen en la ficción dominante, que sigue operando en nuestras maneras de concebir la literatura y el arte? Exploramos el libro de artista (Borsuk, 2020) de Raquel “Kuki” Giubileo, una artista-costurera-ama de casa-discapacitada-prima de Cecilia Giubileo (desaparecida en democracia), que, motorizada por el impulso de archivo (Foster, 2016), reunió 7 papeles cuya ley de consignación (Derrida, 1997) es su propia biografía, para mostrar otra versión de la historia y construir un biodrama (Tellas, 2018) de escrituras múltiples que la vuelven protagonista.

In 1969, circa 1,000 fragments of the Qur’an were found in the space between two ceiling covers in the Holy Shrine of Imam Riḍā in Mashhad, Iran. Some of these were among the oldest Qur’ans produced in Iran. Three volumes in that cache are the only remaining parts of a fourteen-volume Qur’an, copied in Ramaḍān 327/939, endowed to the Holy Shrine by Kishvād b. Amlās. The volume is in vertical format and was copied on paper. Presently, it is the oldest known dated Qur’an manuscript on paper in the world. The similarities of the script and illumination to some undated and unsigned Qur’ans give us some hints about the Kufic script and illuminations in central Iran. The present article discusses the codicological and paleographical features of this copy.

Published: August 2023

This article provides a description and edition of MSS Leiden Or. 14.545 b–c. Radiocarbon dating (14C dating) pinpoints the manuscript to an early period in Islamic history, and this is affirmed by its palaeographical and codicological features. As a result of its dating, it has received considerable attention from scholars and the media. This study confirms the manuscript’s direct relationship with MSS Paris, BnF Arabe 331 and St. Petersburg, National Library, Marcel 3. A verse count analysis was carried out in order to establish its origin. There is evidence that the manuscript journeyed from al-Fusṭāṭ in Old-Cairo to Beirut in Lebanon before finally settling in Leiden in the Netherlands. For several reasons, it was difficult to determine the exact origin of the manuscript.

The morphological ontogeny of Oribatula heterochaeta (Feider et al., 1970) is described and illustrated. The larva of this species has 12 pairs of gastronotal setae including h3 and the nymphs have 15 pairs; most are of medium size and barbed except for short and smooth h3 in the larva and p3 in the protonymph and deutonymph. In the larva, the excentrosclerites are present at four pairs of gastronotal setae (c2, la, lp, h1), and in the nymphs at seven pairs (c2, la, lp, h-series, p1). Comparisons of known morphological ontogeny of species in Oribatula are given.
Revenue, Redistribution, and the Rise and Fall of Inheritance Taxation
Authors: Genschel Philipp , Limberg Julian , Seelkopf Laura
Published: August 2023

Why do countries repeal the inheritance tax? To investigate this question, we use a novel dataset on inheritance tax introductions and repeals worldwide. We argue that revenue requirements are the main determinant of repeal risks: The inheritance tax is resilient as long as it is central to the national revenue system; it becomes vulnerable to attacks once the rise of more efficient tax instruments marginalizes its revenue contribution. Devoid of fiscal purpose, its survival depends mainly on its redistributive features. Redistribution, however, is essentially contested and should be more important in democracies. The evidence is in line with our conjecture: The likelihood of inheritance tax repeal increases as other more buoyant taxes rise and non-democracies are more likely to repeal the tax than democracies.
Thermal management of lithium-ion battery module using the phase change material
Authors: Nagmule Siddharth A. , Salunkhe Pramod B.
Published: August 2023

One of the significant challenges in the fast adoption of electric vehicles in the market is the thermal management of the battery pack. The current advancement in active and passive cooling techniques is helping resolve this issue in electric vehicles. The present work focuses on the use of passive cooling techniques, such as phase change material (PCM) and the heat sink, to maintain the battery module temperature within the thermal safety limit. The cartridge heaters were used as the mock-up cells. A 3 × 3 array of mock-up cells was formed with a cell-to-cell spacing of 6 mm. OM42 was used as a PCM with a melting point temperature of 44°C and latent heat of fusion, 199 kJ/kg. The experiments were conducted at different power settings of 10–40 W with an interval of 10 W. A heat sink was integrated into the bottom of the battery module. It was observed that increased power input reduces the time required to reach the operating temperature limit of 60°C. After incorporating the PCM, this time was extended by 100.8%, 35.5%, 24.7%, and 21.2% for the power input of 10, 20, 30, and 40 W, respectively. Cell-5 was found to be the most heat-affected cell in the battery module. At higher power inputs of 30 and 40 W, the temperature variation along the height of cell-5 was more than 5°C with and without the PCM. The present findings provide more insights into the heat dissipation at lower and higher power inputs, which may help designers to modify the existing battery thermal management system design efficiently.

Recent extensive evidence suggests that ambient fine particulate matter (PM2.5, with an aerodynamic diameter ≤2.5 μm) may be neurotoxic to the brain and cause central nervous system damage, contributing to neurodevelopmental disorders, such as autism spectrum disorders, neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease, and mental disorders, such as schizophrenia, depression, and bipolar disorder. PM2.5 can enter the brain via various pathways, including the blood–brain barrier, olfactory system, and gut-brain axis, leading to adverse effects on the CNS. Studies in humans and animals have revealed that PM2.5-mediated mechanisms, including neuroinflammation, oxidative stress, systemic inflammation, and gut flora dysbiosis, play a crucial role in CNS damage. Additionally, PM2.5 exposure can induce epigenetic alterations, such as hypomethylation of DNA, which may contribute to the pathogenesis of some CNS damage. Through literature analysis, we suggest that promising therapeutic targets for alleviating PM2.5-induced neurological damage include inhibiting microglia overactivation, regulating gut microbiota with antibiotics, and targeting signaling pathways, such as PKA/CREB/BDNF and WNT/β-catenin. Additionally, several studies have observed an association between PM2.5 exposure and epigenetic changes in neuropsychiatric disorders. This review summarizes and discusses the association between PM2.5 exposure and CNS damage, including the possible mechanisms by which PM2.5 causes neurotoxicity.

Objectives

Peripheral arterial disease (PAD) results from the systemic atherosclerotic process. In this study, we aimed to determine the relationship between plasma atherogenic index (AIP), a ratio of molar concentrations of triglycerides to HDL-cholesterol, and long-term outcomes after endovascular therapy (EVT) in patients with superficial femoral artery (SFA) stenosis.

Methods

We retrospectively evaluated 673 patients who underwent EVT for PAD in our tertiary center between January 2015 and December 2020. In the receiver operating characteristic (ROC) curve analysis, the AIP value with the optimum cutoff value was determined as 0.576 to detect the presence of major adverse limb events (MALEs). Patients were divided into two groups according to low AIP (<0.576 as group 1) and high AIP (>0.576 as group 2).

Results

Among the major endpoints, long-term restenosis rates were significantly higher in patients in the high-AIP group than in the low-AIP group ( p<.001). The lower extremity amputation rate was not statistically significant between the two groups. All-cause mortality rate (54 (31.6) versus 117 (68.4), p<.001) was significantly higher in patients in the high-AIP group than in the low-AIP group. In addition, the MALE rate (94 (29.2) versus 218 (62.1), p<.001) was significantly higher in patients in the high-AIP group than in those in the low-AIP group.

Conclusions

In conclusion, we found that AIP is a significant independent predictor of long-term MALE in patients who underwent EVT for SFA.
What makes community-based, multilevel physical activity promotion last? A systematic review with narrative synthesis on factors for sustainable implementation
Authors: Helsper N , Dippon L , Birkholz L , Rütten A , Kohler S , Weber P , Pfeifer K , Semrau J
Published: August 2023

Aim:

To follow the need for more research and strategies to enhance the knowledge of sustainable implementation, we examined cases of community-based, multilevel physical activity-related health promotion after initial funding has ceased and aimed to identify factors that influence their sustainable implementation.

Methods:

Five scientific databases (PubMed; Scopus; Ebsco Host with CINAHL, PsychInfo, and Sportdiscus; ProQuest and Web of Science) were systematically searched for relevant literature in December 2021. Three reviewers performed a title/abstract screening and independently screened the full texts of the remaining papers, followed by a quality assessment. A narrative synthesis method, including qualitative text analysis, was used to synthesise retrieved articles. As starting point, the framework of Schell et al. containing nine domains for sustainability capacity was used and new emerging themes were inductively added.

Results:

The search revealed 270 potentially eligible articles out of 27,652 hits. After the systematic review process, 14 studies were included. In the synthesis, 14 factors influencing the sustainablity of community-based, multilevel physical activity-related health promotion were identified of which six are new factors compared to Schell et al. In particular, our findings bring forth a novel understanding of the importance of the factors ‘Participation and Partnerships’, ‘Empowerment and Capacity Building’ and ‘Community Support’. A dynamic interplay and high connectedness between factors were visible.

Conclusion:

The identified factors can help establish a better understanding of sustainability processes within whole-system approaches intervening on multiple levels in the community with the aim of systems change. They are relevant for practitioners, researchers and policy makers alike. Future research should more closely examine based on further theoretical elaboration how an interplay between the factors can promote sustainability and which interdependencies are of particular importance in facilitating sustainable and equitable change.
Invented Tradition as a Theoretical Approach Within Iranian Memory Studies: A Review
Authors: Rasouli Mohammad
Published: August 2023

This article explores the existing literature on social memory in Iran, a growing research area for studying the country’s past. The scattered and fragmented nature of the literature across disciplines makes an in-depth thematic analysis important to organize these intellectual efforts. The article is divided into two parts. The first part presents a chronological scheme that identifies and discusses three distinct phases of literature development. The second part is a theoretical review demonstrating that memory politics has been the most popular topic in Iranian memory literature. The article adopts two broad paradigms to classify the theories used in the literature: structuralism and symbolic interactionism. Structuralism is the most popular paradigm, while symbolic interactionism is a new trend. The article concludes with recommendations for future researchers working on social memory in Iran.
How I treat posttransplant lymphoproliferative disorder
Authors: Amengual Jennifer E. , Pro Barbara
Published: August 2023

Posttransplant lymphoproliferative disorder (PTLD) is an important and potentially life-threatening complication of solid organ transplant and hematopoietic stem cell transplant (HSCT). Given the heterogeneity of PTLD and the risk of infectious complications in patients with immunosuppression, the treatment of this disease remains challenging. Monomorphic PTLD and lymphoma of B-cell origin account for the majority of cases. Treatment strategies for PTLD consist of response-adapted, risk-stratified methods using immunosuppression reduction, immunotherapy, and/or chemotherapy. With this approach, ∼25% of the patients do not need chemotherapy. Outcomes for patients with high risk or those who do not respond to frontline therapies remain dismal, and novel treatments are needed in this setting. PTLD is associated with Epstein-Barr virus (EBV) infection in 60% to 80% of cases, making EBV-directed therapy an attractive treatment modality. Recently, the introduction of adoptive immunotherapies has become a promising option for refractory cases; hopefully, these treatment strategies can be used as earlier lines of therapy in the future.

Authors: Parker Erin L. , Banfield Michelle , Fassnacht Daniel B. , Phillips Christine B. , Harrison Christopher
Published: August 2023

Background

Anxiety disorders are highly prevalent mental health conditions managed predominantly by general practitioners (GPs). This study aimed to examine the management of anxiety by Australian GPs since the introduction of the Better Access to Psychiatrists, Psychologists and General Practitioners initiative in 2006.

Methods

We conducted secondary analysis of Bettering the Evaluation and Care of Health data on GP encounters for anxiety from 2006 to 2016 (N = 28,784). We calculated point estimates and used multivariate logistic regression to explore the effect of GP and patient characteristics on rates and types of management.

Results

The management rate of anxiety increased from 2.3% of GP encounters in 2006 to 3.2% in 2016. Over the 10-year period, increases were seen in referrals to psychologists (AOR = 1.09, 95%CI = 1.07–1.11, p < .0001) and selective serotonin / serotonin-noradrenalin reuptake inhibitors (AOR = 1.05, 95%CI = 1.03–1.06, p < .0001), and benzodiazepines decreased (AOR = 0.94, 95%CI = 0.92–0.95, p < .0001). Systematic differences in management were found for patient and GP characteristics, including high rates of benzodiazepines in certain groups.

Conclusions

Anxiety is accounting for more of the GP workload, year on year. GP management of anxiety has become more closely aligned with practice guidelines since 2006. However, high rates of benzodiazepine prescribing in certain groups remains a concern. Further research is needed into GP treatment decision making for anxiety.
Investigation of non-National Immunization Program vaccination intentions in rural areas of China
Authors: Wang Xiuli , Fan Yaru , Wang Wei
Published: August 2023

Background

China’s current immunization program was revised in 2007. Some common childhood vaccines such as those for influenza, pediatric pneumonia, Haemophilus influenzae, varicella, and rotavirus have not been included in the National Immunization Program (NIP) and need to be purchased by children’s guardians at their own expense. Rural areas, constrained by economic development and vaccine awareness, have a low non-NIP vaccination rate and more family medical expenses and social burden. This study aims to examine the awareness and attitude of rural parents about non-NIP vaccines and relevant factors influencing their vaccination intention to provide strategic suggestions for expanding and improving the Chinese government’s NIP policy.

Methods

A qualitative method of in-depth interviews were conducted for this study. We interviewed 30 rural parents in a central Chinese village to investigate their awareness of non-NIP vaccines and their vaccination intention and behavior. All the interview data were analyzed through the Colaizzi seven-step data analysis method.

Results

This study summarized the individual and social level factors influencing the non-NIP vaccination intention of rural parents. The individual level factors include four themes: perceived severity with physical harm, treatment consumption (cost of the treatment of the subject diseases), psychological burden, and social consequences being subthemes; perceived vulnerability with age vulnerability, medical history, immune quality (children’s underlying immune status), and environmental vulnerability (sanitary condition of the rural environment) as subthemes; perceived efficacy with effect perception, psychological comfort, protective strength, and functional compensation (functions of non-NIP vaccines unreplaceable by NIP vaccines) being subthemes; and perceived cost consisting of two subthemes cost burden and adverse reaction. The social level influencing factors include the vaccination opinions in rural social networks, the accessibility of health services and vaccine products, and the guidance and promotion of vaccination policies. These factors act outside of individuals’ subjective awareness and influence decisions regarding non-NIP vaccination in rural areas.

Conclusion

Based on these influencing factors, this study constructs a structural model for non-NIP vaccination decision-making process in rural areas of China. The results play a guiding role in directing attention to children’s health, promoting non-NIP vaccination, facilitating the dissemination of vaccine knowledge in rural areas, and improving NIP policies and practices in China.
