Conclui-se que a tarefa editorial da nosostros e este próprio texto são gestos para se garantir a memória de poetas mulheres, retratar seus trabalhos em curso, para afirmar que existem e para poderem persistir no porvir.
De la “gobernanza instrumental mutua” a la “gobernanza del bien común” : hacia unas nuevas relaciones entre universidades y ciudades.
Authors: Collet-Sabé Jordi , Castillo Adrián Josep 
Published: March 2023

The paper aims, first of all, to present the traditional models from which university governance related to community are thought and enact: the “instrumental governance” and the “shared governance or civic engagement”. Secondly, the article shows the theoretical bases of the emergent model of “the common good university governance” based on both the “common good” approach, the Education Cities chart and the UNESCO rapport about education as a global common good. The emergent model of “common good university governance” transforms high education institutions nature and orients them to contribute relevantly to the right to education for all citizens. The paper discusses strengths and weakness of the three models and of some of their most well-known implementations. The paper finishes with a proposal of social and academic debate about five dimensions of this university – community relationship from the common good model: tracking; economy – production; cooperation in knowledge production; research and knowledge transfer; and some transversal issues.
En este artículo sobre la gobernanza universitaria y su relación con el territorio, en primer lugar, se presentan los dos modelos tradicionales de gobernanza universitaria: la instrumental y la compartida o de “civic engagement”. En un segundo momento, se presentan las bases conceptuales de un tercer modelo emergente de “gobernanza del bien común”, basadas en las teorías del bien común, la propuesta de la UNESCO de la “educación como bien común mundial” y la carta de Ciudades Educadoras. Un modelo en el cual las universidades devienen un bien común de la ciudad que puede y debe contribuir de manera notable al derecho a las educaciones de toda la ciudadanía. El artículo debate las fortalezas y debilidades mostradas por los tres modelos y sus implementaciones más relevantes. Para finalizar, se presenta una propuesta para el debate académico y social de cinco ámbitos de actuación en los que se podrían concretar las relaciones entre universidades y ciudades basadas en el modelo de “gobernanza del bien común”: el formativo; el productivo - económico; el de co-construcción de conocimiento; del de investigación y transferencia de conocimiento; y uno final de elementos transversales.

Background
Begomoviruses are circular single-stranded DNA plant viruses that cause economic losses worldwide. Weeds have been pointed out as reservoirs for many begomoviruses species, especially from members of the Sida and Malvastrum genera. These weeds have the ability to host multiple begomoviruses species simultaneously, which can lead to the emergence of new viral species that can spread to commercial crops. Additionally, begomoviruses have a natural tendency to recombine, resulting in the emergence of new variants and species.

Methods
To explore the begomoviruses biodiversity in weeds from genera Sida and Malvastrum in Colima, México, we collected symptomatic plants from these genera throughout the state. To identify BGVs infecting weeds, we performed circular DNA genomics (circomics) using the Illumina platform. Contig annotation was conducted with the BLASTn tool using the GenBank nucleotide “nr” database. We corroborated by PCR the presence of begomoviruses in weeds samples and isolated and sequenced the complete genome of a probable new species of begomovirus using the Sanger method. The demarcation process for new species determination followed the International Committee on Taxonomy of Viruses criteria. Phylogenetic and recombination analyses were implemented to infer the evolutionary relationship of the new virus.

Results
We identified a new begomovirus species from sida and malvastrum plants that has the ability to infect Cucumis sativus L. According to our findings, the novel species Sida chlorotic leaf virus is the result of a recombination event between one member of the group known as the Squash leaf curl virus (SLCV) clade and another from the Abutilon mosaic virus (AbMV) clade. Additionally, we isolated three previously identified begomoviruses species, two of which infected commercial crops: okra (Okra yellow mosaic Mexico virus) and cucumber (Cucumber chlorotic leaf virus).

Conclusion
These findings support the idea that weeds act as begomovirus reservoirs and play essential roles in begomovirus biodiversity. Therefore, controlling their populations near commercial crops must be considered in order to avoid the harmful effects of these phytopathogens and thus increase agricultural efficiency, ensuring food and nutritional security.
A Hybrid Method of Backpropagation and Particle Swarm Optimization for Enhancing Accuracy Performance
Authors: Widiartha I. Made , Gunawan Anak Agung Ngurah , Sanjaya E. R. Ngurah Agus , Sari Kartika 
Published: March 2023

Aims: Backpropagation is an algorithm for adjusting the weight of neural networks in the training stage. The performance of backpropagation has proven superior in optimizing the weight of neural networks; however, this method needs improvement in the initiation stage, where the random process creates local optimal solution. Applying an algorithm based on the global search is an alternative to solve the drawback of backpropagation. One global search method with superior performance is particle swarm optimization. In this research, we apply the hybridization of backpropagation and particle swarm optimization (BP-PSO) to overcome the problem of backpropagation.
Study Design: Research Papers and Short Notes.
Place and Duration of Study: Department of Informatics, Faculty of Mathematics and Natural Sciences, Udayana University, between June 2022 and November 2022.
Methodology: The dataset used in this study is a handwriting image dataset of the mathematical symbol. There are 240 symbols consisting of 180 images for training and 60 for testing. The robustness of the PSO method in obtaining the optimum global solution is expected to help backpropagation out of local optimal solutions. The application of PSO is carried out at the initial weight initialization stage of the artificial neural network. The tuning parameters of the artificial neural network are the number of neurons in the hidden layer and the value of the learning rate. There are three combinations in the number of neurons in the hidden layer, namely 10, 20, and 30. Meanwhile, the learning rate values are five different combinations, namely 0.1 to 0.9, the minimum error value is 0.01, and the maximum number of epochs is 1000. We carry out five repetitions in each test scenario.
Results: The performance results showed that PSO has succeeded in optimizing backpropagation, where the accuracy of the BP-PSO is higher than BP without optimization. The accuracy of BP-PSO is 97.2%, while the BP is 94.4%. The optimal learning rate value and the optimal number of hidden layers are 0.1 and 30 neurons, respectively.
Conclusion: The performance results showed that PSO has succeeded in optimizing backpropagation, where the accuracy of the BP-PSO is higher than BP without optimization. The optimization process of weighting the artificial neural network as the initial weight for later retraining shows a higher average accuracy, while decreasing the average number of epochs does not optimize initial weight.

Published: March 2023

Aim: The study aimed at Investigating of suitability of composting process in treatment of slaughterhouse wastes.
Study Design: The experimental set up was cylindrical bin design with C:N ratios at 30:1 each, and with turning frequencies at every 2 days intervals. Data was generated from the laboratory on the concentrations of selected heavy metals at varying depths of land discharged slaughterhouses. This was used to estimate the level of nutrient build-up in the soil within these environs.
Methodology: Fresh cow dung was collected from Omuigwe slaughterhouse at Aluu, in Ikwere Local Government Area of Rivers State using sterile water rinsed containers. About 36kg of cow dung was collected in each of the three 0.18m3 cylindrical container. Three piles of fresh cow dung were built in a cylindrical design of diameter 0.54 m and height of 0.84 m. Each pile was turned manually using a hand shovel. The MC was measured periodically (precisely every 15 days) and turning operation was in such a way to ensure that every part is well aerated.
Results: Compost results showed high wastes volume reduction ranging from 36.67%, 66.4% and 63.3% for CD, CDSD and CDSH; also, weight reduction at the end of 90days showed a 55.51%, 67.42% and 64.38% reduction for CD, CDSD and CDSH respectively.
Conclusion: The problems of waste generated in our slaughterhouses can be better managed and corrected if proper assessment of the amount of waste generated are properly documented. This would help in accurate prediction of the best method to manage the waste generated.
Tensile strength and knot security of five suture materials exposed to natural summer conditions of a temperate lake
Authors: Reid Connor H. , Cooke Steven J. 
Published: March 2023

Abstract

Objective
Wild fish and other aquatic ectotherms are often subjected to procedures during field research that require wound closure using sutures. A variety of absorbable sutures are available for such purposes, yet degradation processes are highly dependent on temperature, and the environments in which wild ectotherms are released are almost always colder than the conditions for which absorbable sutures are typically designed (i.e., ~37°C). We therefore studied the degradation of various suture materials under a set of biologically relevant conditions for temperate freshwater fish.

Methods
Using a force gauge, we tested the tensile strengths and knot securities of loops tied with five different absorbable suture materials (PDS-II, dyed coated Vicryl, undyed coated Vicryl, plain gut, and chromic gut) prior to and during submersion in a temperate lake over an 8-week period.

Result
The naturally derived collagen-based suture materials (i.e., plain gut and chromic gut) exhibited major decreases in tensile strength within 2 weeks of submersion but maintained relatively high knot security throughout the study period. The synthetic suture loops had poorer initial knot securities that increased following submersion and showed little to no evidence of degradation after 8 weeks.

Conclusion
Variable rates of absorbable suture degradation, or lack thereof, were observed. We discuss the implications of these trends for fish welfare considerations such as suture retention, wound healing, inflammation, and infection under natural conditions.

AbstractPurposeWe measure the dose distribution of gated delivery for different target motions and estimate the gating latency in a magnetic resonance‐guided radiotherapy (MRgRT) system.MethodThe dose distribution accuracy of the gated MRgRT system (MRIdian, Viewray) was investigated using an in‐house‐developed phantom that was compatible with the magnetic field and gating method. This phantom contains a simulated tumor and a radiochromic film (EBT3, Ashland, Inc.). To investigate the effect of the number of beam switching and target velocity on the dose distribution, two types of target motions were applied. One is that the target was periodically moved at a constant velocity of 5 mm/s with different pause times (0, 1, 3, 10, and 20 s) between the motions. During different pause times, different numbers of beams were switched on/off. The other one is that the target was moved at velocities of 3, 5, 8, and 10 mm/s without any pause (i.e., continuous motion). The gated method was applied to these motions at MRIdian, and the dose distributions in each condition were measured using films. To investigate the relation between target motion and dose distribution in the gating method, we compared the results of the gamma analysis of the calculated and measured dose distributions. Moreover, we analytically estimated the gating latencies from the dose distributions measured using films and the gamma analysis results.ResultsThe gamma pass rate linearly decreased with increasing beam switching and target velocity. The overall gating latencies of beam‐hold and beam‐on were 0.51 ± 0.17 and 0.35 ± 0.05 s, respectively.ConclusionsFilm measurements highlighted the factors affecting the treatment accuracy of the gated MRgRT system. Our analytical approach, employing gamma analysis on films, can be used to estimate the overall latency of the gated MRgRT system.

Published: March 2023

AbstractRadiotherapy is one of the most important means of cancer treatment, however, radiation can also cause adverse reactions and even serious injuries to the skin. Radiation‐induced excess reactive oxygen species (ROS) production and inflammatory infiltration make skin wounds difficult to heal compared to normal skin injuries. Herein, an antioxidant heparin‐mimetic peptide hydrogel (K16, KYKYEYEYAGEGDSS‐4Sa) is designed for radiation‐induced skin injury (RISI) repair. First, the K16 peptide can self‐assemble into a hydrogel with a 3D mesh‐like porous nanofiber structure, which can provide certain physical support for skin repair like extracellular matrix (ECM). Then, K16 hydrogel not only scavenges ROS and prevents radiation damage to cellular DNA, but also promotes cell proliferation, migration, and angiogenesis. Meanwhile, 4‐sulfobenzoic acid (4Sa) modified at the N‐terminal end of the K16 peptide can adsorb inflammatory cytokines, thus acting to eliminate inflammation at the wound site. In vivo experiments showed that K16 hydrogel can inhibit early wound degradation, reduce inflammatory infiltration, and promote angiogenesis and collagen deposition, thus promoting wound healing. Therefore, the K16 hydrogel designed in this study has good potential for application in the field of radiation‐induced skin injury repair.
Breaking a Dogma: High‐Throughput Live‐Cell Imaging in Real‐Time with Hoechst 33342

Published: March 2023

AbstractAutomated high‐throughput live cell imaging (LCI) enables investigation of substance effects on cells in vitro. Usually, cell number is analyzed by phase‐contrast imaging, which is reliable only for a few cell types. Therefore, an accurate cell counting method, such as staining the nuclei with Hoechst 33342 before LCI, will be desirable. However, since the mid‐1980s, the dogma exists that Hoechst can only be used for endpoint analyses because of its cytotoxic properties and the potentially phototoxic effects of the excitation light. Since microscopic camera sensitivity has significantly improved, this study investigates whether this dogma is still justified. Therefore, exposure parameters are optimized using a 4× objective, and the minimum required Hoechst concentration is evaluated, allowing LCI at 30‐min intervals over 5 days. Remarkably, a Hoechst concentration of only 57 × 10−9 m significantly inhibits proliferation and thus impairs cell viability. However, Hoechst concentrations between 7 × 10−9 and 28 × 10−9 m can be determined, which are neither cytotoxic nor impacting cell viability, proliferation, or signaling pathways. The method can be adapted to regular inverted fluorescence microscopes and allows, for example, to determine the cytotoxicity of a substance or the transduction efficiency, with the advantage that the analysis can be repeated at any desired time point.

AbstractThe heterogeneity of extracellular matrix (ECM) topology, stiffness, and architecture is a key factor modulating cellular behavior and osteogenesis. However, the effects of heterogeneous ECM electric potential at the micro‐ and nanoscale on osteogenesis remain to be elucidated. Here, the heterogeneous distribution of surface potential is established by incorporating ferroelectric BaTiO3 nanofibers (BTNF) into poly(vinylidene fluoridetrifluoroethylene) (P(VDF‐TrFE)) matrix based on phase‐field and first‐principles simulation. By optimizing the aspect ratios of BTNF fillers, the anisotropic distribution of surface potential on BTNF/P(VDF‐TrFE) nanocomposite membranes can be achieved by strong spontaneous electric polarization of BTNF fillers. These results indicate that heterogeneous surface potential distribution leads to a meshwork pattern of fibronectin (FN) aggregation, which increased FN‐III7‐10 (FN fragment) focal flexibility and anchor points as predicted by molecular dynamics simulation. Furthermore, integrin clustering, focal adhesion formation, cell spreading, and adhesion are enhanced sequentially. Increased traction of actin fibers amplifies mechanotransduction by promoting nuclear translocation of YAP/Runx2, which enhances osteogenesis in vitro and bone regeneration in vivo. The work thus provides fundamental insights into the biological effects of surface potential heterogeneity at the micro‐ and nanoscale on osteogenesis, and also develops a new strategy to optimize the performance of electroactive biomaterials for tissue regenerative therapies.
