Efectos de la densidad bacteriana y velocidad de crecimiento de Isochrysis galbana frente a la adición de cepas con potencial probiótico
Authors:   , Mendoza Rocca Alexandra Lilit
Published: November 2024

El uso de probióticos para la acuicultura de Argopecten purpuratus viene a ser una de las mejores alternativas para enfrentar brotes bacterianos de potenciales patógenos y la alta mortalidad de los estadios larvarios. Considerando que la microalga Isochrysis galbana forma parte de la dieta vital de las larvas de bivalvos, el presente estudio evaluó el efecto de cepas con potencial probiótico (Bacillus halotolerans, PN7A y/o Bacillus safensis, PN4D) sobre el crecimiento de I. galbana no tratada (I.g NT) y previamente tratada con antibióticos (I.g AB). Se analizó la interacción entre la microalga y las bacterias presentes en un cultivo durante 12 días. Los cultivos I.g NT + PN7A y I.g NT + Mix (PN7A + PN4D) tuvieron una menor concentración de microalgas en comparación con el cultivo control correspondiente. En cambio, el cultivo I.g NT + PN4D presentó la mayor densidad de microalgas en el día 8 (2,45 x 107 células ml-1) frente a los demás tratamientos y controles. Asimismo, la densidad de la cepa PN4D inoculada en los cultivos de I. galbana no tratados fue la mayor igualmente en el día 8 (3,0 x 106 células ml-1). Esta cepa tuvo una mejor interacción con la microbiota asociada a la microalga en comparación con la cepa PN7A y la mezcla de ambas cepas. En conclusión, recomendamos suplementar la cepa PN4D a los cultivos de microalgas, ya que mejoró el crecimiento de I. galbana, además de crecer con su microbiota asociada.

Published: November 2024

Objetivos. Evaluar la asociación entre la exposición a diferentes fuentes de publicidad de tabaco, y el consumo de cigarrillos convencionales en adolescentes peruanos. Materiales y métodos. Estudio analítico transversal de datos secundarios de la Global Youth Tobacco Survey (GYTS) 2019 de Perú. La población constó en adolescentes entre 13 a 15 años. Se utilizaron modelos lineales de la familia Poisson para estimar razones de prevalencia junto con sus intervalos de confianza al 95% (IC 95%), que midieron la fuerza de asociación entre la exposición a fuentes de publicidad y el consumo de cigarrillos convencionales considerando posibles factores de confusión en el análisis ajustado. Resultados. Se analizaron los datos de 2083 adolescentes que tenían información sobre exposición a publicidad televisiva, 1092 a publicidad exterior y 2008 a publicidad online. Se observó que la exposición televisiva y online presentaron un incremento en la probabilidad de consumo de cigarrillos convencionales de 1.85 veces (IC 95%: 1.28-2.69; p=0.002) y 1.90 veces (IC 95%: 1.40-2.58; p<0.001), respectivamente. Conclusiones. La publicidad, promoción y patrocinio del tabaco (TAPS) a partir de medios televisivos y online están significativamente asociados al incremento de consumo de cigarrillos convencionales en adolescentes de 13 a 15 años. Por ello, es necesaria la implementación de prohibiciones integrales de TAPS en Perú enfocados en estos medios, para evitar que la industria tabacalera continúe introduciendo publicidad para fomentar el consumo de tabaco.

Eficacia del consumo de probióticos sobre desenlaces orales en niños y/o adolescentes: una revisión sistemática y metaanálisis
Authors:   , Mayta Tovalino Frank Roger
Published: November 2024

Se evaluó la eficacia de los probióticos en los desenlaces relacionados con la caries en niños y/o adolescentes sin enfermedades sistémicas subyacentes. Se realizó un metanálisis exhaustivo de ensayos controlados aleatorizados (ECA). Se realizaron búsquedas en Embase, PubMed, Scopus y Web of Science hasta marzo de 2023. ECA que evaluaran probióticos con una duración mínima de ingesta de 0,2 meses frente a control (ningún tratamiento o placebo) y que informaran de al menos un desenlace primario o secundario. Los desenlaces primarios fueron el número de caries, el recuento de Streptococcus mutans y el recuento de Lactobacillus; los desenlaces secundarios fueron el índice de placa bacteriana, el índice gingival, el pH salival y el índice de sangrado. Se realizaron metanálisis con modelos de efectos aleatorios y el método de la varianza inversa. Los efectos se describieron como diferencia de medias (DM) con sus intervalos de confianza del 95% (IC 95%). El riesgo de sesgo se evaluó con la herramienta RoB 2.0. Se utilizó la metodología GRADE para evaluar la calidad de la evidencia (QoE). Se incluyeron 19 ECA (n=2622), con un intervalo de seguimiento de 0,2 a 108 meses. Los probióticos no tuvieron efecto sobre la reducción de la caries dental (DM -0,24 piezas cariosas, IC del 95%: -0,72 a 0,23; I2= 52%, calidad de la evidencia baja) o el recuento de Lactobacillus (DM -0,78 UFC/mL, IC del 95%: -1,65 a 0,09; I2= 52%, calidad de la evidencia muy baja) frente al control. Sin embargo, los probióticos probablemente redujeron el recuento de S. mutans frente al control (DM -0,40 UFC/mL; IC del 95%: -0,57 a -0,24; I2= 11%; calidad de evidencia moderada)...
Morfometría alveolar en individuos con y sin agenesia del incisivo lateral superior. Un estudio, comparativo retrospectivo
Authors:   , Sánchez Beltrán Jesús Manuel
Published: November 2024

Introducción: Nuestro objetivo fue comparar la morfometría alveolar en adultos jovenes con agenesia del incisivo lateral superior versus el lado sin agenesia y versus controles emparejados.Métodos: En este estudio observacional retrospectivo, se obtuvieron tomografías computarizadas de haz cónico de 36 hemiarcas superiores de adultos jovenes de 15 a 30 años. Los hemiarcas se distribuyeron en tres grupos: grupo 1: 12 hemiarcas superiores que presentaron agenesia del incisivo lateral superior; grupo 2: 12 hemiarcas superiores del lado opuesto sin agenesia del incisivo lateral superior (grupo control 1); y grupo 3: 12 hemiarcas superiores sin agenesia del incisivo lateral superior emparejados por edad y sexo respecto al grupo afectado (grupo control 2). Un investigador capacitado y calibrado realizó todas las mediciones alveolares en dos momentos diferentes, incluidos cortes sagitales, coronales y axiales de cada hemiarca. Pruebas t de Student pareadas, Chi-cuadrado y ANOVA de medidas repetidas con corrección de Bonferroni fueron usados. (P<0,05). Resultados: La evaluación mesial apical del grupo 1 (4,22 ± 1,19 mm) fue significativamente menor (p<0,001) que el de los grupos 2 (6,72±1,17mm) y 3 (7,58±1,67mm). La evaluación apical distal también mostró diferencias(p<0,001)entre los tres grupos, siendo la dimensión menor en el grupo 1 con agenesia (4,53±1,14mm), seguido del grupo 2 sin agenesia (6,23±1,55mm) y el grupo control sano 3 (7,73±1,71mm). Conclusiones: La agenesia de los incisivos laterales reduce significativamente las dimensiones alveolares de la zona afectada. En los casos de agenesia unilateral, el lado no afectado también presenta secuelas, con dimensiones disminuidas respecto a los casos sin agenesia. Esta condición debe tenerse en cuenta a la hora de tomar decisiones terapéuticas en cuanto a rehabilitación con implantes o reemplazo canino.

Area spectral efficiency and coverage probability enhancement for indoor industrial internet of things 5G network
Authors: Sarma Subhra Sankha , Ramanbhai Sagar PareshKumar
Published: November 2024

This article proposes an efficient resource allocation method for Industrial Internet of Things (IIoT) users to communicate among themselves in an underlaying multi-cell mm-Wave 5G cellular uplink network in an indoor environment for enhancing the coverage probability (CP) and area spectral efficiency (ASE) of the network. The IIoT users act as smart sensors in an indoor urban environment where the exchange of information takes place among each other through the 5G cellular network. Interference contributing factors of the mm-Wave band are also taken into account for analyzing its effect on IIoT users. This strictly limits the network coverage due to signal degradation over long distances. Thus, the expression for CP is derived by employing stochastic geometry methods, which improve network performance. Also, the expression for ASE is computed by deriving the probability density function (PDF) of the signal-to-interference plus noise ratio (SINR) at the IIoT end user. Experimental results show a better output of CP of around 0.98 at 1 dB and 0.68 at 5 dB of transmit power for IIoT users with a pathloss exponent of 4. Furthermore, the system also achieves a maximum ASE value of 452 bps⁄Hz/m2 at a distance of 10 m between the IIoT users with a pathloss exponent of 4. Simulation results validate the obtained theoretical values.

Published: November 2024

Background
Multi-lineage differentiation of mesenchymal adult stem cells (m-ASCs) is crucial for tissue regeneration and accompanied with metabolism reprogramming, among which dental-pulp-derived m-ASCs has obvious advantage of easy accessibility. Stem cell fate determination and differentiation are closely related to metabolism status in cell microenvironment, which could actively interact with epigenetic modification. In recent years, glutamine-α-ketoglutarate(αKG) axis was proved to be related to aging, tumorigenesis, osteogenesis etc., while its role in m-ASCs still lack adequate research evidence.
Methods
We employed metabolomic analysis to explore the change pattern of metabolites during dental-pulp-derived m-ASCs differentiation. A murine incisor clipping model was established to investigate the influence of αKG on dental tissue repairment. shRNA technique was used to knockdown the expression of related key enzyme-dehydrogenase 1(GLUD1). RNA-seq, m6A evaluation and MeRIP-qPCR were used to dig into the underlying epigenetic mechanism.
Results
Here we found that the glutamine-αKG axis displayed an increased tendency along with the osteo/odontogenic differentiation of dental-pulp-derived m-ASCs, same as expression pattern of GLUD1. Further, the key metabolite αKG was found able to accelerate the repairment of clipped mice incisor and promote dentin formation. Exogenous DM-αKG was proved able to promote osteo/odontogenic differentiation of dental-pulp-derived m-ASCs, while the inhibition of glutamine-derived αKG level via GLUD1 knockdown had the opposite effect. Under the circumstance of GLUD1 knockdown, extracellular matrix(ECM)function and PI3k-Akt signaling pathway was screened out to be widely involved in the process with insulin-like growth factor 2 (IGF2) participation via RNA-seq. Inhibition of glutamine-αKG axis may affect IGF2 translation efficiency via m6A methylation and can be significantly rescued by αKG supplementation.
Conclusion
Our findings indicate that glutamine-αKG axis may epigenetically promote osteo/odontogenic differentiation of dental-pulp-derived m-ASCs and dentin regeneration, which provide a new research vision of potential dental tissue repairment therapy method or metabolite-based drug research.

Published: November 2024

There is a growing interest in solar electricity generation in many countries worldwide. This trend is the recent installation of photovoltaic panels rather than solar power plants. However, the conversion efficiency of photovoltaic (PV) panels in solar electricity generation is declining due to the accumulation of dust and surface contamination. Furthermore, the process of cleaning photovoltaic (PV) panels situated on the roofs of residential and commercial buildings is a challenging and potentially hazardous task. In this study, the SELFCLEAN PV hydrophilic nano coating was applied to a single photovoltaic panel on a solar energy conversion system at Trakya University Faculty of Engineering, with consideration given to the roof slopes of buildings in Edirne province. During the summer season, when solar radiation is its highest, continuous data was collected over four months. Upon analysis of the results with this application, it was observed that there was an 8.14% increase in energy production in June, a 7.73% increase in July, a 6.34% increase in August, and a 5.34% increase in September, in comparison to the standard PV panel. Furthermore, cleaning PV panels over four months offers labor and cost advantages. Furthermore, water use is not required, significantly contributing to sustainability.

Helicobacter pylori (H. pylori) infection is the established cause of gastric cancer. Although H. pylori eradication is suggested to decrease gastric cancer risk, this has not been fully investigated in general populations. This analysis included 48,530 Japanese men and women aged 40-74 years from four cohort studies. At baseline, the participants provided a self-reported eradication history, and serum anti-H. pylori IgG titers and the atrophic gastritis (AG) severity. We examined the association between eradication history and gastric cancer risk with consideration to H. pylori positivity and AG by Cox proportional hazards regression models. From 2010 to 2018 (average 5.8 years), 649 gastric cancer cases were diagnosed. Compared with those who were negative for both H. pylori and AG as reference, gastric cancer risk was 5.89 times higher (95%CI: 4.41-7.87) in those who were H. pylori positive and/or AG and with no eradication at baseline. Gastric cancer risk among those who underwent eradication before baseline decreased after a temporal increase in risk following eradication (baseline to <1y: HR 1.74, 95%CI 1.18-2.57; 1y to <6y: HR 0.81, 95%CI 0.59-1.11; ≥6y: HR 0.44, 95%CI 0.28-0.68). In a large Japanese general population, H. pylorieradication was associated with long-term reduction in gastric cancer risk.
Weakly Supervised Language Models for Automated Extraction of Critical Findings from Radiology Reports
Authors: Das Avisha , Talati Ish , Chaves Juan Manuel Zambrano , Rubin Daniel , Banerjee Imon
Published: November 2024

Critical findings in radiology reports are life threatening conditions that need to be communicated promptly to physicians (“critical findings”) for timely man-agement of patients. Flagging radiology reports of such incidents could facilitate opportune communication of critical findings. With advancements in natural language processing (NLP), large language models (LLMs) can be trained with task-specific instructions and examples to mine information from narrative texts. We believe that similar methods can be applied to radiology reports to identify and extract critical findings from these reports. However, due to the rarity of such critical events, there is a dearth of manually labeled datasets of critical findings in radiology reports. To overcome this limitation, we train instruction-tuned MISTRAL-based language models in a two-phase weakly supervised fine-tuning setup on unlabeled radiology reports from Mayo Clinic (n=15000). The weakly fine-tuned model is then used to automatically extract critical terms from both internal and external test datasets - Mayo Clinic (n=80) and MIMIC-III (n=123) 1 respectively against the expert-annotation. We also evaluated performance of the models on a large-scale MIMIC-IV reports (n=5000) using automated LLM-aided evaluation metrics - G-eval and Prometheus. We observe that, for both manual and LLM-based evaluations, weakly supervised fine-tuning improves model performance, showing successful task-specific alignment. For community use, we released the trained model with open-source academic license∗

Published: November 2024

Purpose
Since 1990, the Centers for Disease Control and Prevention (CDC)’s National Breast and Cervical Cancer Early Detection Program (NBCCEDP) has offered free cervical cancer screening to low-income, uninsured patients, increasing single time point screening and early detection rates. Little is known about NBCCEDP’s longitudinal effectiveness. The objective of this study was to assess utilization of Kansas’s NBCCEDP, Early Detection Works (EDW) for one-time versus serial screening and compare rates of cervical dysplasia between groups.
Methods
A retrospective cohort study was conducted among patients who received cervical cancer screening through EDW from 2000–2021. Demographic factors, Papanicolaou (Pap) test, and Human papillomavirus (HPV) results were compared between patients with one screening versus multiple. Descriptive statistics were performed.
Results
From 2014–2021, 3.71–7.06% of eligible patients completed screening through EDW annually. 17.4% of 58,582 eligible patients were up to date with screening in 2020. Rural patients and those under age forty were less likely to have EDW screening. Of 43,916 ever-screened patients, 14,638 (33.3%) received multiple screenings. 77% of patients did not have HPV testing; rates were lower in serially screened patients. Cervical dysplasia rates differed minimally between groups.
Conclusion
Despite screening 24,017 patients over 7 years, EDW maintains up to date screening for under one-fourth of eligible Kansans. Young and rural patients less frequently access EDW. HPV testing is underutilized, which limits the negative predictive value of screening. Serial screening is largely used by low-risk patients currently. Identification and prioritization of serial screening in high-risk could increase program impact.

Aditya-L1, the first dedicated Indian solar mission is launched on 02 September 2023 and has been placed in a halo orbit around the first Lagrange point (L1) of the Sun-Earth system on 06 January 2024. Aditya Solar wind Particle EXperiment (ASPEX) is one of the three in-situ science experiments on-board the Aditya-L1 mission that provides measurements of primarily protons and alphas of solar wind, suprathermal, and energetic particles in the energy range from 100 eV to 6 MeV/nucleon. ASPEX consists of two independent spectrometers: Solar Wind Ion Spectrometer (SWIS: 100 eV–20 keV) and Supra Thermal and Energetic Particle Spectrometer (STEPS: 20 keV/nucleon–6 MeV/nucleon). Here, we provide the details of the STEPS configuration, ground calibration, and in-flight performance. After the Aditya-L1’s launch, two STEPS units were switched-on during the Earth-bound phase on 10 September 2023. The STEPS has carried out measurements in the Earth-bound orbit for altitudes > ∼ 8 RE , and also in the cruise phase from Earth to the halo orbit and is continuously operational after insertion to the L1 orbit. The performance of STEPS is as expected during all the phases of the mission so far and all its observations are found to be consistent with the similar measurements from other contemporary instruments at the L1 point.

The present study sought to examine the prevalence and correlates of depression, PTSD, and insomnia in a cohort of Palestinian refugees residing in camps located in Jordan during the outbreak of the War on Gaza on Oct.7th .This is a cross-sectional cohort study that employed the convenient sampling method to recruit Palestinian refugees residing in Irbid and Azmi Almufti camps for Palestinian refugees. Depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9) scale. The self-reported PTSD symptoms were evaluated using the brief PTSD scale, and insomnia severity was assessed using the Insomnia Severity Index -Arabic scale (ISI-A). The data analysis from 258 participants showed that severe depression was reported in 178 participants (69%). Additionally, 127 participants (49.2%) reported severe PTSD symptoms, and 156 participants (60.5%) reported severe insomnia symptoms. Regression analysis revealed that “Residents of Azmi Almufti camp” was a significant risk factor for severe depression (OR = 2.22, 95% 1.28–3.85, p = 0.004) and severe PTSD (OR = 1.81, 95% CI = 1.10–2.99, p = 0.02). The use of over-the-counter antihistamines as a sleep aid was a risk factor for severe insomnia (OR = 3.19, 95%CI = 1.17–8.71, p = 0.02) and PTSD (OR = 3.32, 95% CI = 1.34–8.21, p = 0.01). The conflict in Gaza has been observed to correlate with mental health challenges, particularly among Palestinian refugees residing in Jordan.

Published: November 2024

High precision precipitation estimation with high temporal and spatial resolution is essential for depicting the hydrological process in ecological and environmental researches. Various spatial interpolation algorithms were developed but large uncertainties were found for the Qinghai-Tibetan Plateau (QTP), where meteorological stations are sparsely located over its complex topography. This study developed an Attention-Gated Convolutional Neural Network (A-GCN) algorithm to produce more accurate precipitation spatial interpolation. The spatiotemporal changes were explored in the A-GCN-based precipitation in 1980 to 2020 and its underlying mechanism was analyzed in the view of Asia monsoon. The results showed the A-GCN algorithm, through local connectivity and local region weight sharing in convolutional neural networks, enable better focus on local region features, providing good performance by the comparing with independent observations or the available precipitation datasets. The spatial transition was found in the precipitation interannual trend from a decreasing north and increasing south to an increasing north and decreasing south around the year 2000. The transition could be attributed to the dipole precipitation pattern on a global scale and teleconnection with the Southwest Asia Monsoon enhancing in the early period then weakening since 2005. This study provides a state-of-the-art methodological framework for the spatial interpolation for geographic variable for regions with sparse observations. And precipitation changes would profoundly influence ecological and environment and should be paid more attentions.

Surgical video workflow analysis has made intensive development in computer-assisted surgery by combining deep learning models, aiming to enhance surgical scene analysis and decision-making. However, previous research has mainly focused on identifying coarse-grained surgical phases from surgical videos. In order to provide a more comprehensive fine-grained analysis of surgical videos, this work focuses on accurately identifying triplets  from surgical videos. Specifically, we propose a vision-language deep learning framework that incorporates intra- and inter- triplet modeling, termed I2TM, to explore the relationships among triplets and leverage the model understanding of the entire surgical process, thereby enhancing the accuracy and robustness of recognition. Besides, we also develop a new surgical triplet semantic enhancer (TSE) to establish semantic relationships, both intra- and inter-triplets, across visual and textual modalities. Extensive experimental results on surgical video benchmark datasets demonstrate that our approach can capture finer semantics, achieve effective surgical video understanding and analysis, with potential for widespread medical applications.

In this paper, Si3N4 composite ceramic were synthesized with kerf loss silicon waste powder as the raw material by molten salt assisted nitridation method. Na3AlF6 molten salt was introduced into the system and the effects of Si-salt ratio, nitridation temperature on the nitriding product were investigated. These results indicated that the addition of Na3AlF6 promotes the conversion of waste silicon to Si2N2O, and 90.7% of Si2N2O phase was obtained with the Si-salt ratio of 1:1.5 at 1350℃. The increase in temperature causes the main phase of the product changes from Si2N2O to β-Si3N4, which is due to the decomposition of Si2N2O and the α→β phase transition of Si3N4. And the content of β-Si3N4 phase reached 72.9% with the Si-salt ratio of 1:0.75 at 1450℃. The formation mechanism was analyzed combined with the in-situ nitriding process.

Environmental and behavioral factors have been shown, in experimental settings, to affect neurogenesis in the mouse brain. We found that the density of proliferating neural stem/ progenitor cells (NSPCs) and of neuroblasts was significantly lower in the Subependymal Zone stem cell niche of lab mice when compared with mice and pine voles captured in the wild, with seasonal variation observed only in voles. Moreover, levels of proliferation and neurogenesis were found to decrease in proportion to the decrease in the numbers of chromosomes (from the typical 2n = 40 down to 2n = 26) caused by Robertsonian fusions. In contrast, oligodendroglial progenitors and microglial cells were unaffected by wildlife, seasons and chromosomal fusions. When NSPCs were grown in cultures no differences were detected, suggesting that environmental and genetic effects are mediated by non-cell-autonomous mechanisms. These “real-world” data provide a platform for the identification of systemic factors and genetic loci that control postnatal brain neurogenesis.

Background: The prevalence of ischemic heart disease is increasing in Sub Saharan Africa countries, but adequate data are lacking regarding the in hospital mortality and associated factors.
Objective: To assess the magnitude of in hospital mortality due to myocardial infarction and associated factors among hospitalized patients at two public referral hospitals, Bahir Dar, Ethiopia, 2023.
Methods: Institution based retrospective cross-sectional study was conducted, using sample size of 317, among patients who were hospitalized between November 2020 to December 2023 due myocardial infarction in two public referral hospitals at Bahir Dar, Ethiopia. Pre-developed check list were used to extract data from the medical registry. Data were entered using Epidata Manager Version 4.6 and analyzed using SPSS version 27. Multivariate logistic regression analysis was used, considering with a p-value of <0.05 as statically significant, with a 95% confidence interval.
Result. The in-hospital mortality rate was 21.5% (95% CI: 16.6, 25.9). Age greater than 65 (AOR 6.85, 95% CI 1.58-29.71), presence of diabetes mellitus (AOR 7.02; 95% CI 2.47-19.91), high level of serum troponin (AOR=9.98; 95% CI: 4.06-24.53), elevated serum creatinine (AOR=4.21, 95% CI-1.47-12.08), higher Killip class (AOR-15.52, 95% CI: 5.19-46.46),and STEMI (AOR=5.75; 95% CI-1.66-19.87) were factors associated with in hospital mortality due MI.
Conclusion and recommendation: The in-hospital mortality due MI was found to be high and it was associated with advanced age, high Killip class, STEMI, high serum troponin, diabetes mellitus and high serum creatinine. Addressing these major factors and effective preventive tools are required to reduce this burden.
Filamentous fungi control multiphase flow and fluid distribution in heterogeneous porous media
Authors: Kang Peter , Lee Sang Hyun , Moura Marcel , Srivast Shreya , Santelli Cara
Published: November 2024

Filamentous fungi are ubiquitous across diverse systems and play crucial roles in global carbon and nutrient cycling1–3, soil carbon sequestration4–6, agricultural soil management7–9, contaminant fate and transport10–13, biofouling of engineered materials14,15, and human health16,17. While these processes typically involve multiple fluid phases in porous media, the mechanisms by which fungi regulate fluid flow remain poorly understood, limiting our ability to predict and harness fungi-mediated processes. The complexity and opacity of porous media further obscure our understanding of how fungi influence fluid flow and distribution. In this study, we use a dual-porosity microfluidic chip, featuring a flow channel embedded within tight porous media, to explore the impact of filamentous fungi on multiphase flow and fluid redistribution. Our pore-scale visualizations uncover that filamentous fungi can actively induce multiphase flow and mobilize trapped fluid phases in porous media through localized clogging and hyphal-induced pore invasion, enhancing the oil-water interfacial area and redistribution of fluid phases. This study reveals novel mechanisms by which filamentous fungi influence fluid flow and distribution, offering new insights into harnessing fungal processes to enhance critical applications such as bioremediation and carbon sequestration.

The high soil and climate adaptability of tomato (Solanum lycopersicum L.) is one of the main factors that has sparked worldwide interest in this crop, encouraging its large-scale exploitation. However, this expansion also contributes to the emergence of associated phytosanitary problems, likepathogens such as Alternaria spp., the etiological agent of the disease known as early blight, one of the main diseases that occurs in this crop. Some fungal species have shown positive responses in inducing plant resistance to pathogens. Thus, the aim of this study was to evaluate the effect of the application of fungal filtrates of Ganoderma lucidum, Pleurotus ostreatus andTrichoderma asperellum on the development of A. linariae, as well as its effect on the development and post-harvest of tomato plants grown in a greenhouse and inoculated with the pathogen. For this purpose, evaluations of antagonistic potential, vegetative development, photosynthetic capacity during the crop cycle, and post-harvest quality of the fruits were performed. In vitro test demonstrated that all treatments are effective to control A. linariae and, when tested in greenhouse, were also able to reduce the development of the disease by reducing the area under the disease progress curve and the percentage of severity. Other tests demonstrated that plants treated with filtratedG. lucidumbiomass presented a good physiological response to the induction of resistance against A. linariae and can be used as BCA in the management of diseases in tomato plants, promoting better physiological and productive responses of the crop.
Double Threshold Handover Algorithm for High-Speed Railway Signaling Based on LSTM

Published: November 2024

During the operation of high-speed trains, handovers between base stations are necessary to ensure continuous communication. However, traditional handover algorithms are no longer adequate for the needs of high-speed trains. Therefore, a dual-threshold handover algorithm based on LSTM prediction is proposed to improve communication quality. Firstly, two size thresholds are set. The Long Short-Term Memory (LSTM) neural network is used to predict the handover hysteresis threshold parameters. If the predicted value is less than the smaller threshold, it is replaced by the predicted value; if the predicted value is greater than the larger threshold, it is replaced by the predicted value. The in-depth analysis of the experimental results further elucidates the remarkable advantages of the proposed LSTM based dual-threshold handover algorithm for high-speed rail signal systems. Specifically, this algorithm not only significantly enhances the success rate of handovers but also effectively reduces the ping-pong handover rate, which is crucial for ensuring communication continuity and stability in high-speed mobile environments. This not only alleviates network load but also minimizes communication interruptions and delays caused by frequent handovers, thereby notably improving passengers' communication experience quality.

Published: November 2024

In this paper we investigate the effect of working-from home (WFH) on different components of employees’ job satisfaction, focusing on the role of gender and personality traits. Using longitudinal data from Italy, we estimate a difference-in-differences model, where treated individuals are those who transitioned to remote work due to the COVID-19 pandemic. Our findings reveal that WFH exhibits a positive influence on job satisfaction, albeit exclusively among women, depending on personal characteristics. Specifically, this effect is stronger among women with high levels of openness and agreeableness, whereas those with high neuroticism levels tend to be less satisfied when working remotely.

Ultra High Performance Concrete (UHPC) has been has been used far and wide in architectural field. Wollastonite microfiber (WF) has been shown to be effective in improving the brittle performance of UHPC. In this work, a series of Wollastonite Microfiber-Ultra High Performance Concrete (WF-UHPC) were synthesized by using WF as a low-activity fiber powder admixture to replace parts of cement in UHPC. Due to the smooth surface, the introduction of WF had improved the fluidity of UHPC slurry, which could make it fill all parts of the formwork more evenly. The maximum flexural strength and compressive strength of WF-UHPC could reach 19.5 MPa and 172.6 MPa in 28-day period, which were higher than that of UHPC. Furthermore, microfiber size of WF played a better bridging role, resulting in WF-UHPC possessed better shrinkage inhibition effect. The anti-freezing results indicated that the mass loss and strength loss of WF-UHPC after 300 freeze-thaw cycles were significantly reduced with the addition of wollastonite. This work provides consideration for the innovation of UHPC technology in the future and the research of replacement cement to mineral admixtures in UHPC.

Published: November 2024

With the rapid development of big data and Internet of Things, information sharing has become increasingly important in different information systems. However, the information system includes a large amount of sensitive information such as financial and customer data, which is vulnerable to privacy threats during data sharing. Furthermore, Internet of Things devices are usually resource limited and require lightweight operations. Therefore, it is particularly important to ensure security and high performance while achieving proper big data sharing in Internet of Things based information system. The paper proposes a private and efficient information sharing scheme based on pairing-free attribute encryption algorithm. Firstly, the scheme designs an encryption-based information platform sharing mode, which increases information confidentiality and security with authorized access. Secondly, the scheme proposes an information sharing model to describe the relationships of the entities during information sharing. Finally, the scheme implements detailed algorithms and simulates computation overhead in information sharing. The scheme not only realizes secure sharing of sensitive data in information system, but also ensures privacy and efficiency in information sharing process.
