The accelerated increase in urbanization is generating reductions in green areas and phenomena such as the heat island;for this reason, greening solutions are sought in buildings with the use of the green wall, to mitigate the increase in surface temperature on the facades of single-family homes;the present study evaluates the behavior of surface temperature and relative humidity outside and inside in homes;and the surface temperature and relative humidity in a reinforced masonry green wall façade with concrete blocks using a hydroponic system with the species Nephrolepis exaltata. The results indicate that the exterior surface temperatures and interior relative humidity are higher on average by 5.5 °C and 3.6% than the interior surface temperatures and exterior humidity of the homes;instead, in the green wall prototype, the surface temperature decreases from 8.5 to 7 °C and the relative humidity increases from 5.1 to 6.8%. It is concluded that the green wall with hydroponic system with the species Nephrolepis exaltata reduces the surface temperature and increases the relative humidity outside the reinforced masonry homes with concrete blocks. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The global bamboo market reached USD 70 billion in 2022, and moso bamboo (Phyllostachys edulis) is the species with the greatest international impact. Guadua (Guadua angustifolia Kunth) is a promising species, that has been traditionally used for the construction and manufacture of handcrafts in several countries in Central and South America. In this research, progress was made in the morphological and anatomical characterization of mature guadua culms. On average the culms are 21 m in total length and there are 53.2 kg of dry biomass. The culm morphology was characterized throughout its length;the average diameter, wall thickness, and density at breast height are 14.8 cm, 21.5 mm, and 0.595 g/cm3, respectively. The fibers of the vascular bundles of internode number 7 have an average length of 2146 µm, a diameter of 20.4 µm, and a diameter of 8.7 µm wall thickness. The morphological and anatomical characteristics of guadua offer productive and comparative advantages and could be competitive in the bamboo market. The research, technological development, and innovation processes related to this material should be encouraged to promote the guadua industry. © 2025, North Carolina State University.

Phishing attacks increase by 46% since 2018, mainly affecting the financial sector with losses on average of 3.66 million during 2019. The poor validation procedures of legitimate websites and the carefree aptitude of users in the face of this type of attack have generated their proliferation. The proposed model is divided into the phases of analysis, design, development, experimentation and monitoring;in which the necessary tools are selected, the system architecture is designed considering the criteria of effectiveness, performance, functionality, security and perception of usefulness;It is developed in three layers: backend, middleware, and frontend. The data transfer between the layers implemented the concepts of digital signature in the use of the hash algorithm, asymmetric key and QR codes updated at time intervals. The validation process was carried out using a sample of 106 active users of financial institutions, 100 QR codes, 7 stress loads and in accordance with the ISO 27002 standard. The model reduced the theft of confidential information by 88.87% in an interval of 3 to 6 seconds in the validation process with 100% effectiveness. Likewise, it obtained a 100% satisfaction rate and risk management according to ISO 27002 covered the main inherent risks related to sniffing, QR code spoofing, unauthorized access, cessation of operations and increased latency in the validation process. © 2024 IEEE.

Newborn brains rapidly learn to solve challenging object perception tasks, including segmenting objects from backgrounds and recognizing objects across new viewing situations. Conversely, modern machine learning (ML) algorithms are "data hungry," requiring more training data than brains to reach similar performance levels. How do we close this learning gap between brains and machines? Here, we introduce a new benchmark-a Newborn Embodied Turing Test (NETT) for object segmentation-in which newborn animals and machines are raised in the same environments and tested with the same tasks, permitting direct comparison of their learning. First, newborn chicks were raised in controlled environments containing a single object rotating on a single background, then their recognition performance was tested across new backgrounds and viewpoints. Second, we performed "digital twin" experiments in which artificial agents were reared and tested in virtual environments that mimicked the rearing and testing conditions of the chicks. We inserted a variety of ML "brains" into the artificial agents and measured whether those algorithms learned common object recognition behavior as chicks. All newborn chicks solved this one-shot object segmentation task, successfully learning background-invariant object representations that generalized across new backgrounds and viewpoints. In contrast, none of the artificial agents solved the task, instead learning background-dependent representations that failed to generalize across new backgrounds and viewpoints. This digital twin design exposes core limitations in current ML algorithms in developing brain-like object perception. Our NETT is publicly available for comparing ML algorithms with newborn chicks. We argue that NETT benchmarks can help researchers build embodied AI systems that learn as efficiently and robustly as newborn brains. © 2024 12th International Conference on Learning Representations, ICLR 2024.

Micro-electrode array (MEA) electrophysiological signal analysis by descriptive stochastic tests of the probability density structure

Research on Biomedical engineering 2025年第2期41卷 1-13页

Purpose: The primary objective of this study is to present, analyze, and quantitatively characterize the electrical signals obtained from neuronal cultures coupled to micro-electrode arrays (MEAs). Special attention is given to the temporal evolution of electrical activity across distinct geometric regions of the MEA devices. Methods: The proposed methodology involves signal acquisition, classical analysis based on spike and burst detection, and, critically, the characterization of the probability density structure of the signals. This is achieved through the quantification of Gaussianity—expressed as the percentage of segments non-Gaussian (PSNG)—and stationarity— expressed as the percentage of segments non-stationary (PSNE). Results: Initial analyses showed that first-order power spectral density quantifiers lacked the statistical robustness required to effectively describe the complex components of MEA signals. In contrast, PSNG and PSNE demonstrated strong potential in capturing the different stages of neuronal culture development. Cluster analysis further supported the discriminative capacity of these quantifiers. Conclusion: The phase corresponding to decreased neuronal activity and onset of cell death—a biologically critical stage—exhibited the strongest correlation among the studied variables. These results suggest a discernible biological organization and highlight the relevance of PSNG and PSNE as promising tools for assessing neuronal culture dynamics. © The Author(s), under exclusive licence to The Brazilian Society of Biomedical engineering 2025.

The study aims to analyze the effectiveness of wastewater treatment by using Carica papaya seeds as bio coagulants to diminish total suspended solids (TSS) and excess phosphate. This method has some advantages because it does not use chemical materials, is simple to apply, and is safe for the environment and human health. The wastewater samples were taken from an active laundry site in Palembang City, South Sumatra Province of Indonesia. The study found that the best dosage of coagulant was 3 g for the wastewater samples. The pH and BOD parameters showed slight changes after treatment, with pH 7.63–7.19 and 33–27 mg/L values, respectively. The TSS removal efficiency ranged from 9.3 to 15.6%, while the COD and phosphate removals were obtained from 11.7 to 39.3% and 56.3 to 68.4%, respectively. The treated TSS, COD, and phosphate concentrations have met the Indonesian domestic wastewater quality standard and environmental protection organization (EPO) guidelines. In addition, the statistical analysis and t-test showed significant differences (p © The Author(s) 2024.

International Journal of Industrial and Systems engineering 2022年第1期41卷 71-90页

作者： Fontalvo-Herrera, Tomás José Herrera, Roberto Gonzalez, Yulibeth Industrial Administration Program Faculty of Economics Sciences University of Cartagena Cartagena Colombia Industrial Engineering Program Engineering Faculty Atlantic University Barranquilla Colombia

This research provides a yield-level performance of quality dimensions trough a T-squared control chart and a multivariate capacity indicator to assess the dimensions of the fumigation service. Six Sigma concepts, control charts and multivariate capability indicators were used as the theoretical basis. The research was evaluative, for which all the information regarding the quality dimensions was evaluated in 11 periods of 2019, for which the primary sources associated with the records generated by the fumigation services company were used. As results, the yield level performance was excellent;and the multivariate control chart shows variability in the quality dimensions in the analysed periods;and the multivariate capacity indicator makes it possible evaluate punctually and globally the service quality, showing a good performance. A three-phase method is proposed that allows to evaluate the service dimensions through a periodic, global, longitudinal and multidimensional perspective to guarantee the sustainability of the service quality.
