Background: Since the seminal “Attention Is All You Need” paper (2017), transformer architectures have progressively reshaped sequence modelling far beyond natural‑language processing, including the analysis of multichannel electroencephalography (EEG). Objective: This mini‑review synthesizes research from 2017 to 2025 on transformer‑based EEG models, covering emotion recognition, motor‑imagery (MI) brain–computer...

Breaking the $f_{\text{NL}}$--$b_φ$ degeneracy with the time evolution of tracer number counts

Caio B. de S. Nascimento, Neal Dalal

Constraining local primordial non Gaussianity through scale dependent bias requires an accurate determination of the PNG bias parameter $b φ$, which is completely degenerate with $f \mathrm{NL}$ in the galaxy power spectrum. The standard universality relation predicts $b φ$ from the linear bias, but breaks down for realistic galaxy populations due to PNG assembly bias. The time evolution estimator offers a promisi...

Probing Primordial Cosmology Through BBN Observational Constraints Under Extended Gravitational Dynamics

Abdul Malik Sultan, Manahil Ali, Muhammad Israr Aslam et al.

In this article, We investigate the cosmological consequences of a recently developed $f(R,G,\mathcal{T})$ gravitational framework, in which the action is formulated as a general function of the Ricci scalar $R$, the Gauss Bonnet invariant $G$, and the trace of the energy momentum tensor $\mathcal{T}$. As one of the most reliable probes of the physical conditions in the early universe, Big Bang nucleosynthesis off...

Energy_Paradigm_Shift_Pure_Electric_Civilization

J Y Zhao

This paper examines the global energy transition from fossil fuels to electricity through a multidimensional framework that extends beyond conventional environmental and economic analyses. We propose that this shift represents a fundamental civilizational paradigm transition rather than a mere technological substitution. Our analysis spans five interconnected dimensions: thermodynamic physics, supply chain entropy...

Chemonuclear Transmutation and Noble Metal Synthesis

Hidetsugu Ikegami, Masako Ikegami

In the system of metallike hydride electron donor mixtures, adsorbed hydrogen atoms are transformed into metallic states and alloyed. Dense itinerary s electrons supplied by the electron donor cause a drop in the melting point of metallic hydrogen. As a result, this system reveals thermodynamical liquid activity. The coherent D2 D2 fusion and the D3 D3 chemonuclear fusion are enhanced with factors of 20 to 30 and ...

Axial Obstructions to Rotating Bumblebee Vacuum Solutions

Minyong Guo, Zhong-Ying Fan

We identify two general obstructions to a regular rotating constant norm vector vacua. Firstly, at the poles of a nondegenerate bifurcation surface, horizon and axial invariance force every smooth symmetry inheriting one form to vanish, contradicting a strictly nonzero constant norm. Secondly, we show that a conicity varying along a rotation axis generates a singular curvature that diverges as the inverse proper d...

Probing Nonlinear Logarithmic Kalb-Ramond Black Holes: Particle Dynamics, Epicyclic Oscillations and Thermodynamic Signatures

Aftab Ansari, Rajesh Kumar, Praveen Kumar Dhankar

In contrast to conventional linear coupling frameworks, the proposed work investigated the nonlinear effects that become more significant in the strong field regime of a black hole. We have investigated a new class of Kalb Ramond black holes generated by a nonlinear logarithmic coupling of the field, referred to as a Logarithmic Kalb Ramond black hole. The logarithmic coupling introduces strong field modifications...

NeuroFusion: A Unified Framework for Generalized Visual Stimulus Decoding from fMRI Across Datasets and Subjects

Muhammad Kashif, Matteo Ferrante, Nicola Toschi

Recent advancements in neural decoding have shown promising results in reconstructing visual experiences from brain activity. However, existing approaches focus primarily on decoding within a single dataset or subject, which limits generalization across various sources of neuroimaging. In this work, we propose a novel framework for the decoding of visual stimuli between subjects and between data sets, integrating ...

Enhanced nuclear fusion in the sub-keV energy regime

Micah Karahadian, Matthew Colborne, Arun Persaud et al.

Nuclear fusion requires overcoming or traversing a repulsive Coulomb barrier of hundreds of kiloelectronvolts, rendering the probability of fusion at sub keV energies vanishingly small. Yet in condensed matter, the electronic and structural environment of reacting nuclei can profoundly alter fusion rates. Here we demonstrate that deuterium deuterium fusion within metallic foils exhibits a pronounced reaction yield...

Isentropic Containment of Fusion Plasma Turbulence via Lamarckian Geometric Pruning as a Zero-Loss Commercial Reactor Option

Muhammad Aidil Amry

This paper presents a complementary physical blueprint (The Humble Option) for resolving plasma disruption and thermal leakage within commercial nuclear fusion reactors, such as Tokamaks and Stellarators. Conventional Magnetohydrodynamics (MHD) approaches often attempt to contain non linear plasma turbulence—such as ballooning, kink, and tearing modes—through brute force mechanical magnetic scaling. This tradition...

The Alcubierre drive at the quasiparticle scale: a harder quantum wall and its acoustic analogue

Franklin Octavio Saucedo Moreno

Can the extreme energy requirements of the Alcubierre warp drive be alleviated by shrinking the warp bubble to the scale of a single quantum particle? This work addresses that question through two complementary approaches. First, we re evaluate the quantum inequality constraints governing negative energy densities using an independently verified numerical determination of the optimal sampling constant. The resulti...

Comparison of $f(R,T)$ Gravity with Multiple Datasets

Vincent R. Siggia, Eric D. Carlson

We examine $f(R,T)=R+λT^ε$ gravity models by finding the best fit parameters for various values of $ε$. This is accomplished by analyzing data from the cosmic microwave background, baryon acoustic oscillation observations, cosmic chronometer, and Type Ia supernovae introducing correlations and radiation effects to our previous work. We find the probability distribution for the best fit model around the value of $ε...

Cosmological Evidence for Dark Axion-Dark Baryon Interactions from Apparent Phantom Crossing

Justin Khoury, Meng-Xiang Lin, Mark Trodden

Interactions between dark matter and dark energy can lead to an apparent phantom crossing behavior that mimics the expansion history preferred by the latest cosmological observations from DESI baryon acoustic oscillations (BAO), Cosmic Microwave Background (CMB), and Type Ia supernovae (SNe Ia) data. In a previous paper [Khoury, Lin, and Trodden 2025 arXiv:2503.16415], we proposed a concrete particle physics reali...

Free will beyond confusion: what matters for criminal law, forensic practice, and everyday life

Stephan Schleim

The topic of free will has received much attention in psychology, neuroscience, philosophy and law since the 1990s, the "Decade of the Brain" (Figure 1). What is less well known is that there was already an intensive debate on the topic in German speaking countries in the 19th century, including the calls for a new criminal law, in the 19th century. For example, the German Swiss scientist Carl Vogt (1817 1895), wh...

Large deviations for halos and voids: beyond perturbative non-gaussianities

Martin Teuscher, Ruth Durrer, Julien Grain et al.

The excursion set formalism provides a key connection between primordial density fluctuations and the abundance of cosmic structures such as dark matter halos and voids, traditionally assuming Gaussian random walks. In this work, we extend this framework to fluctuations whose distribution presents strongly non Gaussian tails. Such tails are beyond the reach of perturbative approaches to primordial non Gaussianity ...
