Twisted Shell Topology and Spectral Closure: An Eight-State Phase-Return Construction
ZenodoThis preprint develops a reduced geometric model in which a four-phase compact progression undergoes an orientation reversal after one complete traversal and returns to its full original state after a second traversal. The construction produces an eight-state phase-return orbit from four phase quadratures combined with two return orientations. Removing the uniform phase mode leaves a three-dimensional active sector, and projecting onto the return-restored sector produces a rank-three subspace within the eight-state shell. This gives a normalized active-shell fraction of three-eighths directly from the geometry rather than by fitting. The same three-dimensional active structure is represented through a tetrahedral tight frame and connected to the first nontrivial spherical harmonic sector. This sector has three active components and supplies a natural degree-one map on the sphere, giving a common geometric and spectral origin for several normalization factors used in later shell-based constructions. The paper also studies spectral selection on the twisted compact loop. Once the inactive periodic zero mode is excluded, the first twisted mode becomes the lowest admissible nonconstant branch and has one quarter of the quadratic gradient energy of the first nonzero periodic mode. This provides a spectral distinction between twisted and ordinary periodic closure within the reduced construction. A further result is the separation of distinct primitive closure classes. The paper shows that repeated powers of a single projector cannot generate all of the different coefficients appearing at different perturbative orders. The second-order return contribution and the fourth-order curvature contribution therefore represent distinct reduced structural classes rather than repeated copies of the same operation. The work is deliberately structural rather than phenomenological. It does not derive a measured coupling constant or claim that the reduced topology alone fixes a unique physical stability value. Instead, it establishes the finite-state architecture, projector structure, angular sector, topological degree, and spectral mode relations, while leaving the canonical observable bridge and continuous modulus as open problems for subsequent work.
A new diagnostic method based on support vector machine for short circuit winding faults in induction motors
University of Souk AhrasInter-turn short circuits (ITSCs) in induction motor (IM) windings are among the most critical and frequent faults in industrial environments, as they can rapidly evolve into severe damage, leading to unplanned downtime and costly maintenance. To enhance the reliability of IMs, this paper proposes a machine learning–based diagnosis method dedicated to ITSC failures. The developed diagnostic tool combines a support vector machine (SVM) classifier with Fisher’s ratio (FR)-based feature selection. The proposed framework uses experimentally acquired current signals under healthy conditions and five ITSC fault severity levels (1%–5%), evaluated across four load conditions (25%, 50%, 75%, and 100%). Each signal is segmented into 200 non-overlapping segments (500 samples each), from which nine time-domain features are extracted to capture fault-related characteristics. These features are then used for training and testing a SVM classifier capable of distinguishing between healthy states and levels of severity of ITSC faults. To optimize the classification process, the FR algorithm is employed to select the most informative features while discarding those with low relevance. Our findings unveiled that the proposed hybrid FR-SVM-based diagnosis achieves high diagnostic accuracy ranging from 99.54% to 100%. Furthermore, the outcomes prove that the integrated technical framework (time-domain features + FR + SVM) provides zero false alarms and a balanced diagnostic system that combines computational speed with high precision.
Blood Differential Count effects of Diplazium polypodioides Blume, Diplazium maximum (D.Don) C. Chris. and Stenochlaena palustris edible fiddlehead ferns from Northern Luzon Philippines on ICR mice (Mus musculus)
College of Medicine, Cagayan State University, Carig, Tuguegarao City, Cagayan, PhilippinesDiplazium polypodiodes, Diplazium maximum locally called sarabat 1 and 2 respectively and Stenochlaena palustris or red-fern fiddlehead extracts were evaluated on blood cells of ICR mice. Thirty-two (32) twelve-week-old mice were divided into eight treatments with four per treatment along with positive and negative controls. Mice were fed daily for four weeks with regular food, water plus extracts in low dose (40mg/kg) and high dose (80mg/kg) of sarabat1, sarabat2, and red-fern. Blood was extracted by tail tipping on Day 0, 14, 28 and complete blood count (CBC) with platelets was analyzed. Hematocrit and red blood cells (RBC) was elevated in the positive control but not significantly different with fern extracts with a p-value of 0.119 and 0.208, respectively. White blood cells indicated the negative control and low dose fern extract with mean values of 11.75 and 13.07, respectively, were slightly higher but not significantly different with a p-value of 0.185. Effects on neutrophil and absolute lymphocyte counts follow the same trend with a p-value of 0.249 and 0.119, respectively. Platelet seems elevated in low dose sarabat 1 and 2 as well as low dose red fern but not significant with a 0.370 p-value. Comparison of pre and post-test treatments with extracts of Sarabat 1, 2 and red fern on blood counts at two dosages showed that a mong the parameters tested, only WBC showed a highly significant (0.002) variation at post-treatment which seemed to indicate WBC stimulation which alerts us to caution, while the rest of the differentials are within safe reference parameter ranges. published by the International Journal of Biosciences | IJB
RISK ASSESSMENT OF FUEL OIL BUNKERING OPERATIONS USING AN INTEGRATED HIRARC–HAZOP FRAMEWORK: A CASE STUDY AT A MARINE JETTY TERMINAL
Universitas Negeri MalangIntegrated Terminal Makassar's fuel oil bunkering operations at Jetty 1 and Jetty 2 present significant, intertwined occupational and process hazards. This study analyzed these risks by integrating Hazard Identification, Risk Assessment, and Risk Control (HIRARC) with Hazard and Operability (HAZOP) studies, a novel approach for conventional fuel bunkering. HIRARC identified nine hazards across preparation, transfer, and completion stages, initially rated as low risk, subsequently reduced to low or very low via predominantly administrative controls. HAZOP analysis revealed deeper process deviations underlying these occupational hazards, including communication failures, excessive pressure and flow rates, hose integrity degradation, slippery deck conditions, and inadequate residual fuel handling during completion. The integrated HIRARC-HAZOP framework demonstrates that occupational risks directly correlate with process deviations, a connection often overlooked by single-method analyses. While existing controls are functional, three critical areas require reinforcement: formalizing pre-transfer communication checklists, establishing hose integrity documentation beyond visual inspection, and procedurally mandating the draining and disconnection sequence at operational completion. These refinements aim to enhance safety by moving beyond reliance on spontaneous compliance towards a robust, procedurally driven safety management system.

The life-cost cycle-based sizing of complementary energy storage technologies in DC microgrids
Mustansiriyah UniversityHybrid energy storage system (HESS) configurations have the potential to mitigate the detrimental effects of photovoltaic power generation oscillations on DC microgrid safety and reliability. The economic efficiency of HESS can be improved through the utilization of batteries and their complementary attributes through an energy management strategy. This will allow for the full utilization of the benefits of superconducting magnetic energy storage (SMES), such as high efficiency, lossless energy storage, elevated power density, and rapid response. The battery-SMES HESS is subject to a life cycle cost (LCC) model, along with its associated constraints. System expenditures can be drastically cut by optimizing the HESS capacity layout. The goal function is the lowest LCC, presuming that the power demands of the system are met. Particle swarm optimization takes acceleration into account when designing the capacity of the system. In order to prove that the suggested method of configuring capacity works, a microgrid model is created and tested using numerical data.
A review of field-programmable gate array-based biomedical signal processing for public health applications
Universitas Ahmad DahlanBiomedical signal processing is essential for modern diagnostics, monitoring, and preventive healthcare in public health and mobile health (mHealth) systems. Signals such as electroencephalography (EEG), electromyography (EMG), and heart rate variability (HRV) offer vital insights into brain, muscle, and cardiovascular health. However, achieving real-time, energy-efficient, and scalable processing remains challenging for conventional hardware such as central-processing units (CPUs), graphicsprocessing units (GPUs), and application-specific integrated circuits (ASICs). Field-programmable gate arrays (FPGAs) provide a promising alternative through their reconfigurability, parallelism, and adaptability to dynamic biomedical workloads. This review examines FPGA-based implementations for EEG, EMG, and HRV processing, focusing on key metrics including latency, throughput, and power efficiency. It also discusses design strategies such as low-power optimization, hardware– software co-design, and FPGA-based machine learning acceleration, with attention to data integrity and security in medical contexts. Integration with wearable, portable, and telemedicine platforms is explored, alongside comparative analyses with traditional computing architectures. The paper identifies challenges in power–performance trade-offs, design complexity, and clinical validation, and highlights emerging directions such as artificial intelligence (AI)-driven FPGA platforms, neuromorphic design, and sustainable low-cost solutions for large-scale health monitoring. Overall, FPGA-based biomedical signal processing emerges as a foundation for intelligent, efficient, and accessible next-generation public-health technologies.

Knowledge Management Capabilities and SMES Performance in Computer Village Ikeja, Lagos
Department Department of Business Administration, Chrisland University, AbeokutaIn today’s knowledge-driven economy, effective management of knowledge resources is critical for the competitiveness and sustainability of small and medium-sized enterprises (SMEs). Despite SMEs’ significant contributions to employment and economic development, particularly in Nigeria, many still face constraints such as inadequate infrastructure, limited technology adoption, and informal knowledge-sharing practices. This study investigates the relationship between knowledge management capabilities—comprising knowledge acquisition, application, storage, and creation—and SME performance within the dynamic context of Computer Village, Ikeja, Lagos. Employing a quantitative survey research design, data were collected from 375 SMEs using structured questionnaires and analyzed through descriptive and regression analyses. The results demonstrate that all four dimensions of knowledge management significantly and positively impact SMEs’ performance, influencing areas such as innovation, operational efficiency, and customer satisfaction. Findings highlight the importance of structured knowledge practices over informal methods to prevent knowledge loss and enhance competitive advantage. The study recommends that SMEs invest in digital tools for knowledge storage, cultivate cultures that encourage sharing and innovation, and leverage external collaborations to enrich knowledge bases. These insights are crucial for business owners, policymakers, and stakeholders aiming to harness knowledge as a strategic asset to drive sustainable growth and resilience in Nigeria’s SME sector.

THE EFFECT OF EVENT ACTIVATION ON BRAND AWARENESS AND ITS IMPLICATIONS ON PURCHASE INTENTION OF PROMAG HERBAL PRODUCTS IN BANDUNG
STIE STAN-IMIndonesia's herbal pharmaceutical industry faces challenges in increasing brand awareness and purchase intention through effective event activation strategies. This study analyzes the effect of event activation on brand awareness and its implications for purchase intention of Promag Herbal products at PT. Kalbe Farma Bandung Branch, with brand awareness as a mediating variable. Internal data paradox shows event activation intensity reaches 126.88% of target, yet event sales only achieve 71.32% of event sales target. The study uses quantitative descriptive-verification approach with 110 respondents and SEM-PLS analysis. Test results show: (1) event activation has positive significant effect on brand awareness (β = 0.694; T = 11.016; p < 0.001); (2) brand awareness has a positive significant effect on purchase intention (β = 0.648; T = 8.202; p < 0.001); and (3) brand awareness partially mediates the effect of event activation on purchase intention (VAF = 68.9%). These findings confirm that the quality of event activation is more important than quantity in forming strong brand awareness as transmission mechanism toward consumer purchase intention.

Analysis code and derived data for: Artificial Intelligence Across the Wildfire Management Lifecycle — A PRISMA-Guided Survey of Techniques, Validation Practices, and the Global-South Gap
Universidad Distrital Francisco José de CaldasThis deposit contains the complete analysis pipeline and the derived datasets behind the review article "Artificial Intelligence Across the Wildfire Management Lifecycle: A PRISMA-Guided Survey of Techniques, Validation Practices, and the Global-South Gap" . The review follows a reproducible PRISMA-2020 protocol. A single Scopus query, executed on 29 June 2026 and published verbatim in this deposit, returned 4,463 records, reduced to an eligible corpus of 2,086 journal articles (2015–2025). The article characterises that corpus bibliometrically, formalises how the surveyed methods work, and quantifies validation practice on the corpus itself: fewer than 1% of eligible abstracts mention spatially blocked validation, and only one of the 41 primary studies synthesised reports a spatially blocked protocol. Contents code/ — Python and R scripts that regenerate every reported count, table and figure: PRISMA flow, bibliometric profile, stratified selection pool, supplementary tables, and the keyword co-occurrence network of Figure 3. data/corpus/ — the corpus accession list identifying all 2,086 eligible records (DOI, Scopus EID, year, source, document type, open-access status, citation count, author keywords), plus the exact query string and retrieval date. data/derived/ — annual production, source counts, author-keyword frequencies, the top-50 co-occurrence matrix, Louvain community assignments, PRISMA exclusion logs and the abstract-level term scan results. data/supplementary_tables/ — supplementary tables S1–S3 as CSV. docs/ESM_1.pdf — the article's supplementary material, sections S1–S5. On the raw Scopus export. The raw export is deliberately not included: it carries the Abstract and References fields, which are copyrighted content owned by the individual publishers and licensed to the authors through an institutional Scopus subscription. The accession list identifies the corpus record-for-record, so it can be reconstructed exactly by anyone with Scopus access. Every analysis in the article is reproducible from the files shipped here, with one exception: the abstract-level term scan searches abstract text and therefore requires the licensed export. Its results are included; re-running it requires supplying your own export. See README.md , Section 3. Licences. Code is released under MIT; derived data and documentation under CC BY 4.0. Changes in version 1.1.0. The supplementary material (docs/ESM_1.pdf) is replaced by the version accompanying the manuscript submitted to Environmental Modelling & Software. Section S5 now publishes verbatim the three regular expressions used for the corpus-level term scan, together with the terms they do not match and the direction of that bias. The risk-of-bias wording is aligned with the manuscript, and the reported relation in spread modelling is stated as reported score tracking the breadth of the evaluation rather than its rigour, with the counterexample in the table declared explicitly. The code and the derived data are unchanged from version 1.0.0.
