Published: November 2024

Abstract

The study utilizes novel onion peel (Allium cepa) activated carbon biomass impregnated with magnetic nanoparticles (OMNPs) for the removal of toxic Methylene Blue (MB) and Congo Red (CR) dyes. The SEM analysis reveals the morphological structures, while XRD indicates an amorphous nature. FTIR confirms the functional groups present, TGA demonstrates thermal stability, and the pore size is measured at 2.193 nm. OMNPs reveal a higher sorption rate for both MB and CR dye, with a clearance rate of 96.25% and 93.11%. The thermodynamic reaction is believed to be an exothermic reaction and the process is spontaneous. The simulation investigations indicate that Freundlich is the best-proven isotherm (R2 for MB = 0.9945 and CR dyes = 0.9878), pseudo-second-order kinetics yields chemisorption and ANN is assessed for its fitness (R for MB = 0.993 and CR dyes = 0.984). This new composite material demonstrated remarkable dye removal efficiency, and ANN models accurately predicted adsorption performance.

Published: November 2024

Abstract

Background
In the last decade, Italy has made progressed in adopting the personal recovery-oriented approach. However, full adherence to international recommendations for implementation remains incomplete.
Aims
This study aimed to explore the feasibility, acceptability, and impact of integrating recovery-oriented practices in an Italian Mental Health Service (MHS).
Methods
This pilot study used a longitudinal design with two focus groups. At baseline and follow-up data collected was users’ socio-demographic and clinical characteristics, symptoms, functioning, needs for care, functional autonomy. The Mental Health Recovery Star (MHRS) was used to facilitate and monitor recovery. Professionals and users provided feedback using qualitative interviews. Descriptive analyses were conducted.
Results
Nineteen professionals completed the MHRS with 25 users. From baseline to follow-up users showed an increase in romantic relationship (p<0.001), employment (p<0.001) and addiction (p<0.001), and improvements in the MHRS (p=0.003), functioning (p=0.015), psychopathology (p=0.001), functional autonomy (p=0.003), along with a reduction of unmet needs (p=0.026). Focus groups witnessed active and consistent participation. Both professionals and users positively assessed the study, expressing a desire for more education on recovery, and, generally, saw improved satisfaction and recovery-oriented approaches from baseline to follow-up. Professionals reported higher motivation for work, while users reported comfort sharing views and greater involvement in care, despite some challenges with adherence and collaboration.
Conclusions
The findings indicate the potential for recovery-oriented practices in the MHS, though further efforts are needed for full integration.

Abstract

Pathologic myopia (PM) has long been a leading cause of visual impairment and blindness. While numerous deep learning-based approaches have improved the efficiency and accuracy of recognizing PM, few have thoroughly investigated clinically significant pathological patterns due to the scarcity of datasets with lesion-wise labeling, particularly those comprising ultra-widefield (UWF) images that encompass a broader retinal field of view. In this study, we gather a large-scale multi-source ultra-widefield imaging myopia dataset, PSMM, labeled with posterior staphyloma (PS) and myopic maculopathy (MM). Compared with traditional colored fundus photography, UWF images exhibit informative characteristics concerning peripheral lesions caused by axial elongation and structural deformation in eyes with pathologic myopia. The labels obtained from the dataset can substantially assist in the progression diagnosis of pathologic myopia and guide prognosis. We introduce an end-to-end lightweight framework called RealMNet, which precisely identifies these challenging pathological patterns underpinned by a well-curated dataset. RealMNet is more adaptable to medical devices with only 21 million parameters compared to existing approaches. Through extensive experiments on a unified platform using all-around metrics regarding bipartitions and rankings across three experimental protocols, we demonstrate the robustness and generalizability of RealMNet, showcasing promising merit in clinical applications.

Published: November 2024

Abstract

Over the past few years, there has been significant research on the Internet of Things (IOT), with a major challenge being network security and penetration. Security solutions require careful planning and vigilance to safeguard system security and privacy. Adjusting the weights of neural networks has been shown to improve detection accuracy to some extent. In attack detection, the primary goal is to enhance the precision of attack detection using machine learning techniques. The paper details a fresh approach for adjusting weights in the random neural network to recognize attacks. Reviews of the method under consideration indicate better performance than random neural network methods, Nearest Neighbor, and Support Vector Machine (SVM). Up to 99.49% accuracy has been achieved in attack detection, while the random neural network method has improved to 99.01%. The amalgamation of the most effective approaches in these experiments through a multi-learning model led to an accuracy improvement to 99.56%. The proposed model required less training time compared to the random neural network method.
Enhanced Piezoelectric Performance in ZnO Thin Films by Gallium and Aluminum Doping for Energy Harvesting Applications

Published: November 2024

Abstract

This study investigates the enhancement of piezoelectric properties in zinc oxide (ZnO)-based thin films through gallium (Ga) and aluminum (Al) ion doping, using sol-gel and hydrothermal methods. ZnO is widely used due to its excellent piezoelectricity, chemical stability, and abundance. Ga and Al ions, with radii similar to Zn²⁺, were doped into ZnO films to improve carrier concentration, resistivity, and piezoelectric output. Three doping processes and two concentrations (1% and 3%) were explored, with results showing reduced resistivity, widened band gaps, and increased transmittance for both gallium-doped (GZO) and aluminum-doped (AZO) films compared to pure ZnO. GZO films exhibited superior performance, with the lowest resistivity (0.0065 Ω·cm) and the highest piezoelectric output at 20 Hz. However, excessive doping (3%) increased lattice defects, reducing output power due to stress and electron migration effects. Durability tests confirmed excellent mechanical stability of both GZO and AZO devices under extended vibration, with GZO showing the most stable output power. These findings suggest that Ga and Al doping can significantly enhance the piezoelectric efficiency of ZnO thin films for energy harvesting applications.

Published: November 2024

Abstract

Background
Urban agriculture represents an opportunity to alleviate some of the issues related with the increase in world population and the urbanization process associated. Productive rooftops offer a promising solution allowing to combine food production recycling organic waste and to provide green spaces without consuming urban soils. In addition, harnessing natural resources, including plant-associated microbiomes, is proposed as an effective approach to sustainably improve farm productivity and food quality. However, despite its importance for a better understanding of the interactions between substrates and plants, investigating microbes which inhabit different amendments (including compost and biochar) has received a little attention.
Results
Here, we explored the effects of feedstock materials (spent coffee grounds, coffee silverskin and seaweed biomass) and biochar-blending with compost on horticultural substrate properties, microbial communities, and tomato production. Peat was used as a conventional substrate, for comparison. Substrate properties were mainly defined by the feedstocks, but adding biochar during composting enhanced the quality of the end-products. Overall, alternative substrates differed from peat mainly by showing higher phosphorus content, pH and electric conductivity. Concerning microbial communities, biochar blending was less relevant than the feedstocks. Even though alternative substrates presented higher bacterial diversity than peat, their taxonomic composition remained similar among treatments, reflecting the functional redundancy of the bacterial communities. In addition, we identified specific communities associated with each feedstock, being those associated with composted seaweed biomass positively and significantly correlated with tomato yield.
Conclusions
The studied substrates influenced tomato growth and yield directly via their chemical and physical properties and by influencing microbial community composition. Thus, our results reveal the importance of using the appropriate organic substrate for enhancing the effectiveness of rooftop agriculture while increasing microbial diversity in urban unexploited areas.
Beyond BMI: A Clearer Choice of Flouroscopic Guided PCNL Over USG-PNL in Cases of Central Obesity
Authors: Sipal Timucin , Yilmaz Erdal 
Published: November 2024

Abstract

Purpose: This study aimed to investigate the effect of waist circumference (WS) on Percutaneous Nephrolithotomy (PCNL) compared with body mass index (BMI) in different access techniques: fluoroscopy (FPNL), and ultrasonography (UPNL).
Methods: 109 patients were enrolled in the study in two different centers (63, FPNL-46, UPNL). After investigating the basic 24 parameters, Subgroups were analyzed based on WS ≥ 90 cm and BMI ≥ 30. CT scans determined the stone-free rate (SFR); less than 4 mm stones were accepted as relative SFR. The difficulty level of access was determined using the number of attempted access (NAA) and access times (AT).
Results: Success rates were similar between the groups. In the UPNL group, X-ray time and NAA were lower, but AT was higher (p: 0.018, p: 0.012, p: 0.005, respectively). In the UPNL group, having a BMI ≥30, only prolonged AT, p: 0,029, but having WS ≥ 90 prolonged AT, NAA, and operation time, p< 0.01. In FGPNL, however, WS and BMI did not affect access parameters. In a linear regression analysis, WS and dilatation level predict access time and NAA (p: 0,003 and p: 0,015). Absolute SFR was similar between the groups, with 44,4 % for FPNL and 41,3 % for UPNL, without being affected by BMI and WS.
Conclusion: Even if UPNL is safer regarding radiation exposure, it can be challenging in central obesity. Waist circumference may be a more reliable predictor of this issue than BMI. Despite having similar success rates, FGPNL might be preferable for these patients.

Abstract

The development of new vascular structures is a pre-requisite for tumor growth and spread. This process is often disorganised and produces immature and leaky vessels and relies at least in part on the activity of endovascular progenitor cells (EVPs), residing in vessel walls and giving rise to mature endothelial cells in de novo blood vessel networks in the tumor. Sox9 is a transcription factor that is playing an important role in stem cell self-renewal and fate choice and is highly upregulated in EVPs. In this study, we aimed to explore how Sox9 activity in the endothelium affects tumor vascularisation, microenvironment, and metastasis. Indeed, Sox9 expression was upregulated in tumor endothelial cells of mice harbouring melanomas. Similarly, we observed the up regulation of SOX9 in human endothelial cells exposed to melanoma cell co-culture or conditioned medium resulting in increased colony formation and reduced maturity as revealed in tube formation assays. Endothelial-specific conditional knockout of Sox9 (Sox9fl/fl/Cdh5CreERt2/Rosa-YFP) resulted in a significant reduction in total endothelial cells in B16-F0 or HcMel12 melanoma tumors inoculated intradermally in both flow-cytometry, lineage tracing and immunostaining of tumor sections. Functionally, there was a significant reduction in tumour size and lung metastases after Sox9 deletion in the endothelium. Importantly, despite a major reduction in the number and area of CD31+ vessels there was a significant increase in pericyte coverage suggesting increased maturity of the remaining vessels upon Sox9 deletion in the endothelium. These changes in the endothelium translated into a reduction in hypoxia as demonstrated by decreased GLUT1 expression and reduced nuclear localisation of HIF1α. RNA sequencing of sorted tumor cells as well as spatial transcriptomics of tumor sections with endothelial-specific deletion of Sox9 versus controls confirmed the reduction in hypoxia and showed dramatic increases in CD4 and CD8 immune T cell infiltration in the centre of tumors as confirmed by immunostaining. In summary, endothelial-specific Sox9 deletion resulted in fewer and more mature de novo vessels in the centre of the tumor and reduced metastatic dissemination, suggesting strategies that target this pathway may restore the normal function of blood vessels in tumors and prevent disease progression.

Die Anwendung von pädagogischer Diagnostik benötigt sowohl konzeptuelles als auch strategisches Wissen über diagnostische Entscheidungsprozesse. Um diese Entscheidungsprozesse für die Ausbildung im Lehramt Sonderpädagogik der Hochschule möglichst anwendungsbezogen nachzustellen, wurde ein digitales fallbasiertes Simulationsspiel entwickelt. Ziel ist es, angehende Sonderpädagog:innen im Studium zu ökonomischen diagnostischen Entscheidungen im Rahmen pädagogischer Diagnostik zu befähigen und den Aufbau von Handlungsschablonen zu fördern. Diese Studie untersucht mittels Learning Analytics, inwieweit die Simulationsspiele zur Weiterentwicklung der diagnostischen Entscheidungskompetenz von Studierenden (N = 30) beitragen. Untersucht wird, wie treffsicher und effizient Studierende aus fünf Testverfahren den jeweils passenden Test auswählen. Der wiederholte Einsatz der Simulationsspiel führt zu signifikanten Veränderungen in der Entscheidungsheuristik. Studierende treffen ihre Entscheidungen nach der Übung mit durchschnittlich 2,1 Tests und einer Treffsicherheit von 41,39%. Die Einsatzmöglichkeiten und der Mehrwert von digitalen Simulationsspielen wird für die Lehrer:innenausbildung diskutiert.
Abstract
It is essential that teachers possess a comprehensive understanding of the conceptual and strategic aspects of the diagnostic decision-making process. A digital case-based simulation game was developed with the objective of enabling prospective special education students to make economic diagnostic decisions in the context of educational diagnostics and to promote the development of action templates. This study employs learning analytics to ascertain the extent to which the simulation games contribute to the further development of the diagnostic decision-making skills of students (N = 30). The study examines the accuracy and efficiency with which students select the appropriate test from five test procedures. Repeated use of the simulation game leads to significant changes in decision-making heuristics. Students make their decisions after the intervention with an average of 2.1 tests and an accuracy of 41.39%. The added value of digital simulation games in teacher training is discussed.

Igualmente, se reflexiona acerca del carácter problemático del concepto de realidad en relación con el yo, en donde se hace referencia a Descartes, Kant y Husserl y a algunas observaciones de filósofos de la antigüedad griega y romana. A su vez algunos estudiosos actuales de la escuela de Kioto. Esto con la intención de mostrar un camino de acceso a la persona y a la vacuidad. Posteriormente se incursiona en la discusión acerca de la primera persona, imprescindible en la experiencia de la vacuidad, allí tematizamos aspectos de la fenomenología de Husserl en relación con el pensamiento de Nishitani y su idea de persona.
Lo intolerable (mandato) y lo imposible (anuncio): Nota sobre el sacrificio de la metafísica a partir de J.-L. Marion
Authors: Mingo Alicia 
Published: November 2024

Nuestra aproximación al fenómeno saturado en J.-L. Marion se realizará mediante los ejemplos de mandato y anuncio que se dan en el ámbito de la revelación. Con ellos justamente se pretende llamar la atención sobre la necesidad de una fenomenología de la donación que abarque lo que desde nuestra comprensión humana se rechaza como intolerable, e incluso imposible, atendiendo sin embargo a fenómenos saturados que no se limitarían a un determinado ámbito, como algunas críticas parecen sugerir cuando se refieren al “giro teológico” en la fenomenología (Janicaud, 1991). La donación exige ser reconocida, y que no nos opongamos a ella de entrada por nuestras inclinaciones metafísicas hacia la objetividad, el cálculo, el control, la predicción, etc. En este sentido nos referimos a un sacrificio de la metafísica, acreditando la oportunidad para que pudiera desmentirse lo que parece hacerla imprescindible (más que meramente necesaria), y a favor de nuevas posibilidades del pensar y del enriquecimiento de la experiencia. Para ello sería de suma relevancia proteger la confianza en la donación, incluso en los casos más extremos, que en nuestros ejemplos también dan crédito a la libertad.
