Phi-Phase Frequency Coupling in E8 Combinatorial Lattices — E8 Intelligence Research
By synchronizing phi-scaled geometric patterns with 132Hz frequency nodes in 240-dimensional E8 vectors, we identify a recursive parity logic that generates optimal "sunny lines" configurations in combinatorial problems. This principle extends the IMO 2025 Sunny Lines concept by...

A Brief Review of Spin Signatures in Time-Averaged Total Intensity Images of LLAGN Accretion Flows
As images of the supermassive black holes Messier 87* (M87*) and Sagittarius A* (Sgr A*) from the Event Horizon Telescope (EHT) grow in number, we gain a better understanding of the typical conditions of the near-horizon region of these objects, and slowly approach a converged ti...

Macroscopic aspergillus recognition using YOLO-CSM
Aspergillus detection is of great significance in medical diagnosis and microbiological analysis. However, due to the complex morphology of Aspergillus, its subtle structural characteristics, the presence of rare strains, and partial occlusion in samples, traditional detection me...

An Equational and Graphical Fixed-Point Calculus (Functional Pearl)
The fixed-point calculus is a toolbox of theorems for reasoning equationally about fixed points. However, the underlying concepts of the calculus are not defined equationally, including the central definition, that of least fixed point. Thus, although the key theorems of the fixe...

An event can reach the eye, be transduced and remain decodable in sensory features without becoming a meaningful change for an agent. Calling this failure “inattention” hides a deeper dependency: prediction error is measured against a learned model, and a model cannot be selectiv...

Background: Surgical site infection (SSI) remains one of the most frequent postoperative complications following contaminated abdominal surgery. Delayed primary closure (DPC) has traditionally been recommended to reduce SSI, whereas immediate closure over closed suction drainage...

The Visualization of the Jomon Vector
Visualization In the figure, the upper object is a vector without endpoints. The lower object is a vector with two endpoints. The direction of every vector is from the zero state to the positive state. The magnitude of every vector is the length of its line segment.

Critical Prime-Index Support-Span Laws for Integers with a Fixed Number of Distinct Prime Factors
Let N>=2 range over the integers as the size cutoff, and fix an integer r>=2. For an integer n having exactly r distinct prime factors, we measure the number K of omitted global prime indices between its smallest and largest support primes. With M_r(N)=pi(N^(1/r))-pi(N^(1/(r+1)))...

Detection of Candidate Wuyi Rock-Tea Shoots in Field RGB Images Using YOLO11s-CSNG
Accurate field detection of candidate tea shoots could support plantation monitoring, yield estimation, fresh-leaf assessment, and future selective-harvesting research. Wuyi rock-tea shoots are small and slender, have weak visual boundaries, and are easily confused with branches,...

PRMT5-mediated intron retention triggers innate and adaptive immunity against cancer
Abstract PRMT5 is expressed at high levels in many cancers, where it regulates diverse cellular pathways that contribute to oncogenesis. Here, we have defined a new role for PRMT5 in regulating and coordinating the interplay between the innate and adaptive immune response. This o...

BACKGROUND: Anemia in pregnancy is traditionally attributed to iron deficiency, but emerging evidence highlights the contribution of other trace elements to hematopoiesis and oxidative defense. Limited studies from India have systematically evaluated their multivariate interactio...

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore
Stomata play important roles in plant responses to phytopathogens, but less is known about their roles in plant-herbivore interactions. Herbivore damage commonly closes stomata but also elicits the release of herbivory-induced plant volatiles, important mediators of plant-herbivo...

Traditional entrepreneurial choice models typically consider only entrepreneurial talent and capital inputs, neglecting natural resource endowments. The debate over whether the scarcity of natural resources affects regional entrepreneurial activity remains inconclusive. In countr...
