The Unified Theory of Informational Spin: A Coherence-Based Framework for Gravitation, Cosmology, Quantum Systems The Unified Theory of Informational Spin (TGU) proposes a reformulation of physical reality in which information—organized into coherent patterns termed informational spin—is treated as a fundamental organizing substrate. Within this framework, gravitational phenomena are interpreted as emergent effects of informational coherence gradients, offering an alternative description to conventional mass–energy-based formulations. TGU aims to unify general relativity, quantum mechanics, biological systems, and computational science under a single coherence-centered paradigm. The model introduces a phenomenological correction factor for orbital dynamics, α = 1 + k ·e/a, where the Matuchaki Parameter k ≈ 0.0881 arises from geometric considerations related to the normalization of a three-dimensional coherent spin field. Numerical implementations of this correction demonstrate convergence with general relativistic predictions in weak-field regimes and generate distinctive deviations in high-strain or highly eccentric systems. Across multiple domains, TGU provides a coherent interpretative framework capable of reproducing known orbital precession results, modeling galactic rotation behavior without invoking additional matter components, and generating testable predictions for cosmological observations, condensed-matter systems, and biological information processing. Rather than treating gravity as purely geometric curvature, TGU reframes it as an informational effect governed by coherence dynamics, positioning informational coherence as a unifying principle underlying physical, biological, and computational phenomena.

In situ, antibody-independent, and multiplexed characterization of amyloid plaques by MALDI MS/MS imaging using iprm-PASEF Amyloidosis collectively describes a heterogeneous group of protein aggregation-based diseases involving the misfolding and extracellular accumulation of fibril-forming amyloid proteins. Diagnosing amyloidosis is difficult due to its many subtypes (e.g., AA, AL, ATTR), with varying symptoms. Current diagnosis often involves Congo red staining, but it has limitations in quantification and specificity. A novel method called iprm-PASEF exploits MALDI imaging and offers a faster, spatially resolved, antibody-independent technique for identifying peptides while preserving tissue structure. In this study, iprm-PASEF was used to further evaluate its applicability on amyloidosis. FFPE slides of an amyloidosis TMA including biopsies of 18 amyloidosis-positive tissues were prepared for tryptic peptide MALDI imaging. An initial MALDI TIMS MS1 measurement was performed, followed by the manual generation of a precursor list containing mass-to-charge ratios and ion mobility windows. In a second iprm-PASEF measurement, the selected precursors are analyzed in a multiplexed MALDI MS/MS mode. Peptide identification was achieved through peptide-to-spectrum matching using MASCOT. Within the course of this study, we characterized an amyloidosis TMA consisting of AA, AL, and ATTR amyloidosis diseased tissue with MALDI imaging of tryptic peptides. We successfully identified eight amyloidosis-related peptides derived from serum amyloid A, vitronectin, apolipoprotein E, serum amyloid P component, and transthyretin receptor in one single iprm-PASEF measurement. Peptide signals mapped to amyloidogenic plaques determined in a Congo red staining. Some of these peptides were specifically found in ATTR and AA amyloidosis. This represents a significant step towards integrating MALDI imaging into the diagnostic process for amyloidosis.

Accelerating Inverse Design of Optical Metasurfaces: Analytic Gradients of Periodic Green's Functions via Quasi-Modular Forms The inverse design of nonlocal metasurfaces requires the precise optimization of lattice geometry to engineer spatial dispersion and high-Q resonances. However, gradient-based optimization is frequently bottle-necked by the evaluation of the periodic Dyadic Green's Function (DGF), where traditional Finite Difference (FD) methods suffer from an inherent trade-off between truncation error and numerical instability near spectral singularities. In this work, we present an end-to-end Analytic Gradient Engine for 2D Bravais lattices. By mapping the spectral lattice sums of the Coupled Dipole Approximation (CDA) to the theory of Quasi-Modular Forms (QMF), we derive exact, closed-form expressions for the gradients of the interaction matrix with respect to the modular lattice parameter $τ$. Our framework explicitly handles conditionally convergent terms via regularization and addresses the non-holomorphic outlier $σ_4^{(2)}$ via a hybrid numerical strategy. We further introduce a robust evaluation scheme combining $SL(2, \mathbb{Z})$ domain reduction with automatic error certificates. Experimental validation demonstrates that our engine achieves machine-precision derivatives ($10^{-15}$) and a 6.5$\times$ speedup in optimization convergence compared to finite-difference baselines, enabling the robust design of giant anisotropy in regimes where traditional methods fail.

Dynamic behavior of graphene-origami-based meta-auxetic doublet nanobeam with memory-dependent effect Abstract This work explores the mechanical characteristics response electro-magneto-thermoelastic (EMT) nanobeams by simultaneously accounting for fractional viscoelasticity, nonlocal elastic interactions, doublet mechanics, and couple-stress effects. A meta-auxetic architecture is integrated into the nanobeam inspired by graphene-based origami structures, allowing its mechanical behavior to be tuned through geometric reconfiguration and engineered microstructural features. Time-dependent viscoelastic phenomena—such as nanoscale stress relaxation and strain evolution—are captured using the Caputo-form Atangana–Baleanu fractional operator representing the material’s memory characteristics. The governing relations are formulated through Hamilton’s principle under a nonlocal couple-stress formulation. Because these equations are nonlinear and fractional in nature, the Adomian decomposition technique (ADT) is applied to obtain analytical solution approximations. A comparative study with previously published results is carried out for model verification. The results demonstrate that couple-stress behavior, fractional-order memory effects, auxetic properties arising from graphene-origami structures, doublet mechanics, and nonlocal phenomena all strongly influence the stress–strain behavior and thermal response of the nanobeam. Overall, the study offers important guidelines for designing and optimizing next-generation nanoscale systems, including biomedical sensors, reconfigurable electronics, adaptive façade components, and intelligent infrastructural materials.

Nonlinear photon emission and discharge mode transitions in HVDC needle–needle electrodes: Insights from UV photon spot distribution mapping This study proposes a methodology for the development of ultraviolet (UV) spot distribution mapping with probabilistic processing, with the objective of addressing the challenges associated with the monitoring of partial discharge (PD) in high-voltage direct current (HVDC) equipment and analyzing its mechanism. An experimental platform with adjustable needle–needle electrodes (5–25 mm gap) was established to simulate insulation defects, enabling quantitative analysis through a dedicated UV image processing framework. The research demonstrates that the transition of photon counting characteristics from bell-shaped to U-shaped distributions with increasing electrode distance is governed by the spatial reorganization of discharge regions. UV spot distribution mapping reveals that this nonlinear behavior stems from expanded UV emission zones at larger distances and constrained discharge region coalescence at smaller gaps, while spectral red-shift toward infrared wavelengths during discharge intensification further modulates photon counting patterns. A unified mathematical model was developed, incorporating both spatial and spectral evolution mechanisms. The unified model, designated as, has been shown to be effective in this regard. Spatial analysis identified characteristic discharge core zones with pronounced polarity asymmetry. The probabilistic methodology effectively discriminates between persistent discharge zones and random photon events, enabling quantitative assessment of discharge stability and evolution. The findings establish a framework correlating UV spot distribution dynamics with photon counting behavior, providing both fundamental insights into DC PD mechanisms and practical methodologies for insulation condition assessment in HVDC systems.

A design of methane gas detection system based on second harmonic spectroscopy In non-laboratory settings, high-precision detection of methane gas is vulnerable to noise and environmental interference. To address this issue, we propose a methane detection system that utilizes tunable semiconductor laser absorption spectroscopy technology combined with second harmonic detection. This system employs a hardware-algorithm collaborative design architecture to effectively suppress noise. In comparison to commercial non-dispersive infrared sensors, the detection limit of our system is reduced to 4.81 ppm, demonstrating enhanced long-term stability. The Allan variance is measured at 4.38×10-7 over a duration of 147 seconds. Experimental results indicate that the system exhibits good response linearity within the range of 0-1000 ppm, with a coefficient of determination (R2) of 0.9818. This research offers a reliable solution for industrial methane monitoring, and the portable design concept may serve as a valuable reference for the development of other gas sensing systems.

Prediction of Remaining Life and Insulation Failure of High-Voltage Distribution Cable Using Statistical Methods Predicting the remaining life and insulation failure of high-voltage distribution cables using statistical methods is essential for ensuring the reliability and safety of electrical power systems. Statistical techniques enable the identification of degradation trends by analyzing historical operational and diagnostic data. The paper examines the life expectancy of 10 kV Paper-Insulated Lead-Covered (PILC) cable insulation. The presented experiment was performed on both used and new cable samples. Presumptions of Weibull distribution parameters for random variables “breakdown voltage” and “breakdown time” are experimentally validated. The exponent of life expectancy for both used and new cable samples is obtained from experimentally derived parameters of the Weibull distribution. As a result, the dependence quantile for the breakdown probability of used and new cables is determined.

Typical Soil Physical and Chemical Characteristics in the Highland Area of Dak Lak Province, Vietnam Background: In the highland area of Dak Lak province, Central Vietnam, nearly 300,000 ha are covered with ferralitic soils. One of the main obstacles to agricultural production in the region is the low fertility of ferralsols. The current study attempts to relate the features of soil samples by presenting data on 10 physical and chemical aspects. Methods: 85 composite soil samples that were collected from five communes in Dak Lak province representing for the highland area, were taken from the 0-30 cm layer at the beginning of the crop season in December 2024. They were air dried and sieved at a 2 mm mesh, then were analyzed to physico-chemical characterization using standard laboratory techniques in 2025. Result: According to our findings, all of these soils have sand greater than 38% and clay less than 26%, an average of higher than 3% organic matter and are acidic (pH in KCl less than 5). As a result, the cation exchange capacity (CEC), which averages greater than 10 cmolc kg-1, is rather high. Simple correlation and principal component (PC) analyses were used to look at the structure and mutual interference of the 10 variables. The 85 soil samples were separated based on their potassium (PC3 axis), organic matter (PC2 axis) and texture (PC1 axis). Further research will devote to soil characteristics following cropping patterns in order to consider the suitable management practice for sustainable production in this highland area.

DESIGN AND DEVELOPMENT OF A LOW - COST FULLY AUTOMATED HORIZONTAL COCONUT SINGULATION AND INSPECTION SYSTEM The coconut processing industry largely depends on manual handling for feeding and quality inspection, which leads to labor dependency, inconsistent sorting, and reduced productivity.To address these challenges, this paper presents the design and development of a low-cost fully automated horizontal coconut singulation and inspection system.The proposed system automatically feeds coconuts from a bulk heap and places them one by one onto a horizontal conveyor without any human intervention.A specially designed hopper with an anti-jamming mechanism and a motor-driven singulation gate ensures controlled and continuous coconut flow despite size variations.For quality inspection, a vision-based software module is employed to detect coconut presence, validate shape, accommodate size tolerance, and identify surface defects such as cracks.Image processing techniques are used to classify coconuts as acceptable or defective, and an automatic rejection mechanism is triggered accordingly.The integration of mechanical automation, control logic, and software-based inspection improves reliability while maintaining low system cost.The experiment has shown the possibility of placing objects one by one with high stability for horizontal alignment and accuracy in inspection.The system that was suggested is the one that can be used in small and medium-scale coconut processing applications as a solution that is both cost-effective and scalable.
