Humanidades digitais e estudos históricos do léxico
Authors: Finatto Maria José Bocorny 
Published: January 2024

No contexto desenhado por uma nova transdisciplina (GOLUB, LIU, 2021) denominada Humanidades Digitais (DH), como linguistas, situamos o desafio de extrair dados e conhecimentos dispersos a partir de arquivos digitais que trazem registros de língua escrita ou falada. Já em meio a esse cenário ou um tanto distante dele, na área de Letras, temos toda uma tradição de trabalhos linguísticos, lexicológicos, lexicográficos e afins dedicados a estudar documentos escritos antigos, impressos e manuscritos. A antiguidade dessas fontes, naturalmente, é sempre uma condição relativa. As DH têm se situado na interseção da Computação e das Humanidades. E, ao lidar com dados digitais em cronologias, envolvem pesquisa trans- e multidisciplinar colaborativa, reunindo especialmente historiadores e documentalistas, trazendo ferramentas e métodos digitais para o estudo das Humanidades e dos patrimônios históricos resguardados em formatos on-line. As DH dialogam com novas formas de ensino e pesquisa, nas suas realidades presenciais, remotas e on-line, ao mesmo tempo em que criticam como novos formatos e modalidades impactam o patrimônio cultural e a cultura digital. Assim, as DH compõem importante campo de pesquisa em crescimento. Um campo para o qual os estudos da linguagem e as Ciências do Léxico, especialmente se conjugados com as tecnologias do Processamento de Linguagem Natural (PLN) e da Linguística de Corpus, têm muito a oferecer. Afinal, existem muitas técnicas de pesquisa linguística, feitas com algum apoio computacional, que podem fornecer ajuda útil para o estudo de textos históricos, de literaturas e de qualquer outro discurso humano que esteja sob investigação nessas condições.

Published: January 2024

AbstractPremature birth may result in specific cardiovascular responses to hypoxia and hypercapnia, that might hamper high‐altitude acclimatization. This study investigated the consequences of premature birth on baroreflex sensitivity (BRS) under hypoxic, hypobaric and hypercapnic conditions. Seventeen preterm born males (gestational age, 29 ± 1 weeks), and 17 age‐matched term born adults (40 ± 0 weeks) underwent consecutive 6‐min stages breathing different oxygen and carbon dioxide concentrations at both sea‐level and high‐altitude (3375 m). Continuous blood pressure and ventilatory parameters were recorded in normobaric normoxia (NNx), normobaric normoxic hypercapnia (NNx + CO2), hypobaric hypoxia (HHx), hypobaric normoxia (HNx), hypobaric normoxia hypercapnia (HNx + CO2), and hypobaric hypoxia with end‐tidal CO2 clamped at NNx value (HHx + clamp). BRS was assessed using the sequence method. Across all conditions, BRS was lower in term born compared to preterm (13.0 ± 7.5 vs. 21.2 ± 8.8 ms⋅mmHg−1, main group effect: p < 0.01) participants. BRS was lower in HHx compared to NNx in term born (10.5 ± 4.9 vs. 16.0 ± 6.0 ms⋅mmHg−1, p = 0.05), but not in preterm (27.3 ± 15.7 vs. 17.6 ± 8.3 ms⋅mmHg−1, p = 0.43) participants, leading to a lower BRS in HHx in term born compared to preterm (p < 0.01). In conclusion, this study reports a blunted response of BRS during acute high‐altitude exposure without any influence of changes in inspired CO2 in healthy prematurely born adults.
Arterial desaturation rate does not influence self‐selected knee extension force but alters ventilatory response to progressive hypoxia: A pilot study
Authors: Farra Saro D. , Jacobs Ira 
Published: January 2024

AbstractThe absolute magnitude and rate of arterial desaturation each independently impair whole‐body aerobic exercise. This study examined potential mechanisms underlying the rate‐dependent relationship. Utilizing an exercise protocol involving unilateral, intermittent, isometric knee extensions (UIIKE), we provided sufficient reperfusion time between contractions to reduce the accumulation of intramuscular metabolic by‐products that typically stimulate muscle afferents. The objective was to create a milieu conducive to accentuating any influence of arterial desaturation rate on muscular fatigue. Eight participants completed four UIIKE sessions, performing one 3 s contraction every 30s at a perceived intensity of 50% MVC for 25 min. Participants voluntarily adjusted their force generation to maintain perceptual effort at 50% MVC without feedback. Reductions in inspired oxygen fraction (FIO2) decreased arterial saturation from >98% to 70% with varying rates in three trials: FAST (5.3 ± 1.3 min), MED (11.8 ± 2.7 min), and SLOW (19.9 ± 3.7 min). FIO2 remained at 0.21 during the control trial. Force generation and muscle activation remained at baseline levels throughout UIIKE trials, unaffected by the magnitude or rate of desaturation. Minute ventilation increased with hypoxia (p < 0.05), and faster desaturation rates magnified this response. These findings demonstrate that arterial desaturation magnitude and rate independently affect ventilation, but do not influence fatigue development during UIIKE.

Authors: Garti Ines , Berbiche Mohamed 
Published: January 2024

Abstract
In this paper, we investigate the global existence and finite time blow-up
of solution for the Cauchy problem of one-dimensional fifth-order Boussinesq
equation with logarithmic nonlinearity. Fist we prove the existence and
uniqueness of local mild solutions in the energy space by means of the
contraction mapping principle. Further under some restriction on the initial
data, we establish the results on existence and uniqueness of global
solutions and finite time blow-up of solutions by using the potential well
method. Moreover, the sufficient and necessary conditions of global
existence and finite time blow-up of solutions are given.
Numerical Approximation of Gaussian Random Fields on Closed Surfaces
Authors: Bonito Andrea , Guignard Diane , Lei Wenyu 
Published: January 2024

Abstract
We consider the numerical approximation of Gaussian random fields on closed surfaces defined as the solution to a fractional stochastic partial differential equation (SPDE) with additive white noise. The SPDE involves two parameters controlling the smoothness and the correlation length of the Gaussian random field. The proposed numerical method relies on the Balakrishnan integral representation of the solution and does not require the approximation of eigenpairs. Rather, it consists of a sinc quadrature coupled with a standard surface finite element method. We provide a complete error analysis of the method and illustrate its performances in several numerical experiments.
Structure, flexibility and hydration properties of lignin dimers studied with Molecular Dynamics simulations
Authors: Hackenstrass Klara , Hasani Merima , Wohlert Malin 
Published: January 2024

Abstract
Lignin is an abundant polymer found in wood and grasses, but due to its heterogeneity and complex macromolecular structure it has been less utilized than cellulose. While the building blocks are known, the way they are linked is less understood. Here, Molecular Dynamics simulations were used to systematically characterize seven linkages found in native lignin. Their influence on lignin and water structure, and their interactions were analyzed. The study is limited to guaiacyl (G-G) dimers connected by the following common softwood linkages; 5-5′, 4-O-5′, α-O-4′, β-1′, β-5′, β-O-4′ and β-β′. The simulations show that the linkage has a significant effect on conformational preference and lignin-water interaction. Especially, the behavior of the β-O-4′ shows unique properties, both in terms of conformational freedom and interaction with water. Within the β-O-4′ dimer, π–π stacking between the aromatic rings is possible. The molecule has two distinct common conformations, one compressed and one extended. These preferences also lead to a different effect of β-O-4′ dimer on the surrounding water, where water is found close to the linkage itself but expelled from the aromatic rings to a larger extent than the other linkages. These findings are important for lignin solubility as well as its depolymerization mechanisms.

Abstract
Modifying the energy landscape of existing molecular emitters is an attractive challenge with favourable outcomes in chemistry and organic optoelectronic research. It has recently been explored through strong light–matter coupling studies where the organic emitters were placed in an optical cavity. Nonetheless, a debate revolves around whether the observed change in the material properties represents novel coupled system dynamics or the unmasking of pre-existing material properties induced by light–matter interactions. Here, for the first time, we examined the effect of strong coupling in polariton organic light-emitting diodes via time-resolved electroluminescence studies. We accompanied our experimental analysis with theoretical fits using a model of coupled rate equations accounting for all major mechanisms that can result in delayed electroluminescence in organic emitters. We found that in our devices the delayed electroluminescence was dominated by emission from trapped charges and this mechanism remained unmodified in the presence of strong coupling.

Published: January 2024

Abstract
The rapid development of the aviation industry has attracted great attention to aviation safety, and the identification and early warning of low-level wind shear have become crucial. Therefore, it is also necessary to improve the performance of laser wind radar technology and achieve accurate recognition of low-level wind shear. In this regard, this study is based on laser wind radar technology and uses the K-neighborhood frequency method to denoise radar data. And based on the least squares fitting method, two-dimensional synthetic wind shear is obtained, and a low altitude wind shear recognition model based on laser wind radar is constructed. These test results confirm that the correlation coefficient values of the wind speed fitting curve measured by the laser detection radar on sunny, cloudy, and fog days are 0.978, 0.954, and 0.961, respectively. And the correlation coefficient values of wind direction fitting curve are 0.984, 0.982, and 0.952, respectively. On sunny, cloudy, and fog days, the recognition accuracy values of the low-level wind shear recognition model are 85.92, 82.17, and 72.43%, respectively. And the recognition accuracy values of wind analyzer radar are 70.18, 62.57, and 55.89%, respectively. In practical applications, the low-level wind shear recognition model accurately recognizes the occurrence of low-level wind shear. This study has achieved accurate recognition of low-level wind shear and has better performance compared to other existing radars. It has played an important reference role in aviation safety.
Spectral uncertainty analysis of grassland and its camouflage materials based on land-based hyperspectral images

Published: January 2024

Abstract
Spectral uncertainty is one of the most prominent spectral characteristics of hyperspectral images. Compared to the process of remote sensing hyperspectral imaging, hyperspectral imaging under land-based imaging conditions has the characteristics of variable detection directions, random imaging times, and complex environmental conditions, resulting in increased spectral uncertainty of targets in land-based hyperspectral images. The spectral uncertainty of the target mainly refers to the phenomenon of “Same spectral reflectance but different objects” and “Same object but different spectral reflectance” which poses significant difficulties for subsequent hyperspectral image target detection and recognition. In order to analyze the spectral uncertainty of hyperspectral images in land-based applications and address the issue of spectral uncertainty in similar targets, a spectral uncertainty evaluation index based on standard deviation vector was proposed. For the overall spectral separability between different types of targets, a quantitative index based on Jaccard Distance (JD-SSI) is proposed to measure the spectral separability of different kinds of targets. The experiment focused on grassland and its four typical camouflage materials, analyzing the spectral intra class differences and inter class separability of each target with grassland. It is a fundamental work for studying the spectral characteristics of land-based hyperspectral images, providing a new approach for subsequent spectral band extraction, hyperspectral image classification, and target detection tasks.
Rodents/Shrews and their Ectoparasites are not Associated with the Enzootic Maintenance and Transmission of Coxiella burnetii to Livestock and Humans in Puducherry, India
Authors: Indhu Prathibha A , Rekha V Bhanu , Hariharan R , Ajay Kumar V J , Lakshmy S , Kasirajan Anand , Madhavan Thirumurthy , Panneer D 
Published: January 2024

Objectives:
“Q fever,” which is caused by Coxiella burnetii, is endemic in India. In addition to livestock, rodents have also been reported to be associated with enzootic maintenance, favoring pathogen transmission. Currently, however, no data are available on the role of rodents in “Q fever” transmission in India.

Methods:
A cross-sectional study was undertaken in 39 Puducherry villages to screen Coxiella burnetii in synanthropic rodents (rats and shrews) and their ectoparasites (ticks, mites, and fleas) by real-time and conventional PCR protocols targeting the pathogen specific IS 1111 and com 1 genes.

Results:
One hundred forty animals were trapped (107 shrews and 33 rats). The ticks, mites, and fleas infesting the rodents were identified as Rhipicephalus sanguineus, Leptotrombidium deliense and Schoengastiella spp., and Xenopsylla cheopis, respectively. PCR screening of the DNA extracted from the rodent/shrew blood samples and their ectoparasites tested negative for C. burnetii.

Conclusions:
Synanthropic rodents, such as rodents/shrews and their ectoparasites do not have a pivotal part in the enzootic maintenance and spread of Q fever to humans and livestock in Puducherry.

Published: January 2024

Klebsiella pneumoniae bacteremia is one of the leading causes of sepsis that has a high mortality rate. The effect of multidrug resistance and different virulence of Klebsiella pneumoniae on mortality is still controversial. This study aimed to determine the impact of hypervirulent K. pneumoniae (hvKp), MDR, and clinical characteristics on mortality of K. pneumoniae bacteremia patients. A retrospective cross-sectional study was conducted on K. pneumoniae bacteremia cases of patients hospitalized at Professor dr. I.G.N.G Ngoerah General Hospital from December 1, 2020, to May 31, 2021. A positive PCR of rmpA, iucA genes, and/or a positive string test was identified as hvKp. The mortality rate of 51 K. pneumoniae bacteremia patients samples (aged 0-74 years) was 72.5%, in which 9.8% (5/51) of them were hvKp and 51% of the isolates (26/51) produced the Extended Spectrum Beta Lactamase (ESBL). Furthermore, 9.8% (5/51) of the cases were carbapenem-resistant. Thus, hvKp, MDR, gender characteristics, and comorbidities do not significantly affect the mortality of K. pneumoniae bacteremia patients. Multivariate logistic regression analysis showed that sepsis (odds ratio (OR) 4.29; p=0.038) and adult age group (mean 50 years) (OR 3.75; p=0.039) are independent predictors with a significant effect on mortality of K. pneumoniae bacteremia patients. Careful and integrated management of K. pneumoniae bacteremia patients is essential for better outcomes, especially in sepsis and elderly patients. Although hvKp prevalence is low, emerging MDR-hvKp in health facilities is a severe concern for further actions and research.

Authors: Sholihah Fitria , Usman Hermin Aminah , Dewayani Birgitta Maria 
Published: January 2024

Background: Acral melanoma (AM) is a subtype of malignant melanoma (MM) that has a predilection for glabrous skin and is the most common type of melanoma among Asians. Depth of invasion is one of the prognostic factors in AM. VDR may have an association with depth of invasion in AM. However, reports from Asian patients are still lacking. The aim of this study was to explore the association between VDR immunoexpression and depth of invasion in AM patients in Bandung, Indonesia.Methods: This study was a retrospective cross-sectional study that analyzed the nuclear and cytoplasm VDR expression of melanoma cells and its association with Breslow’s thickness in patients with AM in Dr. Hasan Sadikin General Hospital Bandung. VDR immunostaining was performed on paraffin blocks. The Breslow thickness was measured using dot slide software. Chi square statistical analysis was done to determine the results.Results: Of the 30 patients, 73% had a Breslow thickness of >4 mm. There was a significant inverse association between nuclear VDR immunoexpression and Breslow thickness of AM (p<0.001), but not for cytoplasmic VDR immunoexpression (p=0.914). Conclusion: Low nuclear VDR immunoexpression is associated with the depth of invasion in AM. Nuclear VDR immunoexpression possibly affect progression and should be considered before administration of vitamin D therapy in AM.
