Ripe “Citrus maxima,” also known as pomelo, is mostly the same based on their appearance and skin color. For this instance, the classification of pomelo sweetness is quite tricky. According to a study, ripe fruit produces ethylene (C2H4) gas associated with fruit ripening level. The odor comes from molecules in the air that stimulate receptors in the nose. The senses of smell and taste are directly related because they use the same type of receptors. Since the senses of smell and taste are related to each other, the researcher used the pomelo's smell or gas for the classification of sweetness. In this case, the researchers create an automated system that will classify the pomelo sweetness in a non-invasive procedure through E-nose. The study's objective is to help pomelo industries in classifying the sweetness of their product before selling it to the consumers. Also, it aims to develop a device to help satisfy the purchase of consumers of sweet pomelo. Since ethylene sensor is quite expensive, MQ3, MQ6, and MQ8 gas sensors are used to detect the gas emission produced by pomelo. The three MQ sensors are connected to the Arduino Uno microcontroller to analog reading in parts per million (ppm). For data gathering, data mining is used for data clustering and classification. The accuracy of the system is verified in an invasive procedure, specifically testing its “total sugar content.” The pomelos were first subjected to data gathering in the manufactured device. These pomelos were then extracted for their pure natural juice and sent to a laboratory testing to get its total sugar content percentage. Laboratory results of pomelo juices in total sugar percentage have been analyzed to verify the effectiveness of the non-invasive procedure in classifying the sweetness of citrus maxima. The laboratory and non-invasive results verified that the total sugar content could be identified correctly by the e-nose. Thus, MQ3, MQ6, and MQ8 gas sensors are capable of detecting pomelo

In this paper, a novel Z-number based Fuzzy Neural Network (Z-FNN) is proposed for dynamic system identification. The architecture and learning algorithm of the proposed Z-FNN are designed. The inference mechanism of Z-FNN is based on distance measures and interpolative reasoning. The structure of the Z-FNN is accordingly designed using an interpolative reasoning scheme. Genetic Algorithms (GA) is applied to update the unknown parameters of the network. The proposed Z-FNN system is applied for dynamic plant identification. Its performance is compared with those obtained by the use of other approaches from the literature and it is proved that the proposed approach is a suitable alternative for practical applications that are characterized by uncertain and imprecise information. © 2022, The Authors.

Liquid crystals have proven to provide a versatile experimental and theoretical platform for studying topological objects such as vortices, skyrmions, and hopfions. In parallel, in hard condensed matter physics, the concept of topological phases and topological order has been introduced in the context of spin liquids to investigate emergent phenomena like quantum Hall effects and high-temperature superconductivity. Here, we bridge these two seemingly disparate perspectives on topology in physics. Combining experiments and simulations, we show how topological defects in liquid crystals can be used as versatile building blocks to create complex, highly degenerate topological phases, which we refer to as ‘Combinatorial Vortex Lattices’ (CVLs). CVLs exhibit extensive residual entropy and support locally stable quasi-particle excitations in the form of charge-conserving topological monopoles, which can act as mobile information carriers and be linked via Dirac strings. CLVs can be rewritten and reconfigured on demand, endowed with various symmetries, and modified through laser-induced topological surgery — an essential capability for information storage and retrieval. We demonstrate experimentally the realization, stability, and precise optical manipulation of CVLs, thus opening new avenues for understanding and technologically exploiting higher-hierarchy topology in liquid crystals and other ordered media.

The use of the MathML language made possible to improve the accessibility of mathematics for blind or low-vision persons in digital media. Synthetic speech technologies have advanced significantly using MathML, however, the speech synthesizers' standard reading style is still not suitable for mathematics. Making mathematical reading of the speech synthesizers more natural and expressive is still a challenge. The creation of models to produce the appropriate prosody in the synthesized speech of math content is therefore necessary, as shown in previous research. This article presents a proposal for a model to improve prosody in the synthesized speech of mathematical expressions based on MathML. A corpus of mathematical expressions spoken by Mathematics teachers was created to support the model's development. The Fujisaki intonation model was adopted for intonation control, accent and phrase commands have been extracted from the corpus, and some adjustments have been made to manipulate prosodic parameters in the speech of mathematical expression in correlation with the MathML tree; additionally, a pattern of pauses control is being created.

X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) have been used to characterize the polyimide film based on 4,4′ hexafluoro-isopropylidene -bis pthalic anhydride (HFDA) and 4,4′ -bis (4-aminophenoxy) biphenyl (APBP). Films of varying thicknesses made from diluted precursors were studied by IR and XPS. An elemental analysis and a tentative peak assignment for C 1s in XPS is presented. The HFDA-APBP thick films are stoichiometric in composition and binding energies are in good agreement with data on hexafluorodianhydride-oxydianiline (HFDA-ODA). For thinner films, certain chemical modifications were observed at high cure temperatures.

Modern superconducting qubits based on two-dimensional (2D) transmons typically involve the growth of Nb thin films on high-resistivity Si substrates. Since imperfections at the Nb-Si heterointerface have been implicated as a source of two-level systems that limit quantum coherence times, detailed characterization and understanding of niobium silicide interfacial layers are critical to improving superconducting qubit technology. While bulk binary intermetallic niobium silicide phases are well understood, the thermodynamic phase stability and properties of ultrathin niobium silicides, such as those found at the Nb-Si heterointerface in 2D transmons, have not yet been explored. Here, we report finite-sized effects for ultrathin niobium silicide films using density functional theory calculations and predict nanoscale stabilization of Nb6Si5 over the bulk α−Nb5Si3 phase. This result is consistent with our experimental observations of a niobium silicide interfacial layer between a sputtered Nb thin film and the underlying Si substrate. Furthermore, our calculations show that Nb6Si5 nanofilms are nonmagnetic, making them superior to nanofilms of α−Nb5Si3 that exhibit antiferromagnetic correlations detrimental to long coherence times in superconducting qubits. By providing atomic-scale insight into niobium silicide nanofilms, this paper can help guide ongoing efforts to optimize Nb-Si heterointerfaces for long coherence times in superconducting qubits.

Access to safe drinking water has progressively declined. Methods of purifying saltwater include reverse osmosis and distillation, but require cost and energy that may not be accessible to many. Another method for desalination is electrodialysis that imposes a voltage field to induce net movement of chlorine and sodium ions through two semipermeable membranes, resulting in water having a lower salt concentration. Electrodialysis has lower financial cost and energy requirements, showing promise as a potential method that may be more accessible in developing regions. To encourage education and exploration of this method for desalination, this project is developing an educational web-based informational site and interactive graphical program. Users can interact and visualize net movement of charged ions within voltage fields, and in the presence of semipermeable membranes. As these educational webbased tools would be available globally to anyone with a web assessible device, many people may be able to access and become knowledgeable about and interested in the potential of electrodialysis. © 2020 IEEE.

E-voting is an electronic voting information technology service, while E-participation is an information technology service for citizens of the public to provide reports, polls, or suggestions on government policies electronically. The Technology Services E-Participation-VOT (EPV) model is a combined E-Participation and E-Voting service model. The concept of this service model is that citizens transform from E-participation and E-voting services into an EPV model. The purpose of this model is to provide information to participants (citizens) about online-based voting services. This method of developing the EP-Voting Anticipation (EPV) technology model uses agile methods that are effective and flexible in various cases of designing Information Technology models for Information Technology (IT) services that apply a Framework Information Technology Infrastructure Library (ITIL). The results obtained from this study are an Information Technology service system model that provides recommendations for participation in conducting electronic elections (E-Voting). © 2020 IEEE.

Noninvasive optical imaging modalities can probe patient's tissue in 3D and over time generate gigabytes of clinically relevant data per sample. There is a need for AI models to analyze this data and assist clinical workflow. The lack of expert labelers and the large dataset required (>100,000 images) for model training and tuning are the main hurdles in creating foundation models. In this paper we introduce FoundationShift, a method to apply any AI model from computational pathology without retraining. We show our method is more accurate than state of the art models (SAM, MedSAM, SAM-Med2D, CellProfiler, Hover-Net, PLIP, UNI and ChatGPT), with multiple imaging modalities (OCT and RCM). This is achieved without the need for model retraining or fine-tuning. Applying our method to noninvasive in vivo images could enable physicians to readily incorporate optical imaging modalities into their clinical practice, providing real time tissue analysis and improving patient care. © 2024, CC BY-NC-ND.
