Study of projectile fragment emission in the fragmentation of 28 Si on carbon and copper targets at 130 A MeV

The emission angle distributions, the transverse momentum distributions, and the temperature parameters of the emission source of projectile fragments produced in the fragmentation of 28 Si on C and Cu targets at 130 A MeV are investigated using CR-39 nuclear track detectors. The...

Which ETFs Protect Against U.S. Equity Crashes? Regime-Dependent Hedging and Safe-Haven Evidence from DCC-GJR-GARCH

Which liquid ETFs actually protect investors when U.S. equities crash? This paper answers that question using daily observations from 2012-03-02 to 2026-02-27 for SPY and eight cross-asset ETFs spanning gold, oil, broad commodities, the U.S. dollar, Treasuries, real estate, high-...

On the quadratic twist of elliptic curves with full 2-torsion

Let [Formula: see text] be an elliptic curve with full [Formula: see text]-torsion group, where [Formula: see text] and [Formula: see text] are coprime integers and [Formula: see text] is a square. Assume that the [Formula: see text]-Selmer group of [Formula: see text] has rank t...

Cross Sector Closure Tests of Strong Gravity with Orbits, Photon Geometry, and Ringdown

Orbital timing, black hole imaging, and ringdown probe strong gravity through timelike, null, and perturbative dynamics, but they are commonly analyzed separately. We formulate and implement a shared coupling closure test that requires one dimensionful gravity coupling to reprodu...

Impact of Hu-Sawicki Corrections in f ( R,T ) Gravity on the Dynamical Evolution of Self-Gravitating Compact Fluids

In the context of minimally matter-geometry coupled gravity, the dynamical stability of axially symmetric, self-gravitating compact objects is investigated in this paper. We look into the nature of anisotropic star structures using a formalism of Hu-Sawicki inspired f(R,T) gravit...

Geometry-dependent chaos: A unified framework for anisotropic dynamical systems via Trinition deformation

This work develops a Trinition-based framework for geometry-dependent chaotic dynamics. The Trinition construction is represented on a three-component primitive space, while its multiplication law generates both an anisotropic quadratic geometry and an additional interaction-acce...

Dynamic adjustment and load balancing of 6G network resources for the instantaneous peak demand of concerts

With the rapid advancement of 6G networks, managing network resources efficiently in high-demand environments such as live concerts has become increasingly important. Concerts, characterized by large crowds and high data traffic due to real-time multimedia streaming, pose signifi...

Smile asymptotics for Bachelier implied volatility

We investigate the asymptotic behaviour of the Bachelier implied volatility tails, extending the large-strike results established for the Black-Scholes implied volatility. Exploiting the theory of regular variation, we derive explicit expressions for the Bachelier implied volatil...

Perceptual misalignment of texture representations in convolutional neural networks

Mathematical modeling of visual textures traces back to Julesz's intuition that texture perception in humans is based on local correlations between image features. An influential approach for texture analysis and generation generalizes this notion to linear correlations between t...

Weak solutions for a generalized Katugampola fractional Langevin inclusion with boundary condition

We investigate weak solutions of a fractional Langevin inclusion subject to a nonlocal boundary condition and involving the generalized Katugampola-Caputo derivative. The problem is posed in a real Banach space and the multivalued nonlinearity is treated through Pettis-integrable...

Application of Tikhonov's theory to an age-structured singularly perturbed SIS model with a general treatment function

We consider a simple SIS model with a general nonlinear treatment function. We combine it with a demographic model, keeping in mind the difference in time scale. A slow-fast system emerges. Our purpose is to show how Tikhonov's Theorem for singularly perturbed systems can be appl...

Impact of Public Health Interventions on the Co-infection Dynamics of COVID-19 with Tuberculosis

COVID-19 and tuberculosis (TB) co-infection presents a significant public health challenge by increasing disease burden and complicating disease management, diagnosis, and treatment. To explore the COVID-19-TB co-infection dynamics and evaluate interventions such as public health...

An axially symmetric stationary N-center solution of Einstein's vacuum equations

Using the Euclidon method [1–3], a stationary solution of Einstein's vacuum equations was obtained, describing N rotating axially symmetric masses, which in the absence of rotation describes N arbitrary axially symmetric static masses, for example, N Erez-Rosen masses having arbi...

Anisotropic Traversable Wormholes in Modified Gravity: Geometric Structure and Stability Analysis

This manuscript investigates the viability and stability of traversable wormholes within f(ℚ,ℒm) gravity, where ℚ represents non-metricity scalar and ℒm denotes the matter-Lagrangian. The corresponding anisotropic field equations are derived by employing the Morris-Thorne metric...

Neutron–hidden-neutron mixing as an effective component of galactic dark matter

We investigate the possibility that neutron–hidden-neutron mixing provides an effective source of dark matter through the non-trivial vacuum condensate associated with fermion mixing in quantum field theory. In a static and spherically symmetric curved spacetime, the mixed-vacuum...

A complete characterization of indices of nonic number fields defined by x 9 + ax 2 + b

The main goal of this paper is to calculate the index of any nonic number field [Formula: see text] generated by a root [Formula: see text] of a monic irreducible trinomial [Formula: see text]. Namely, for every rational prime [Formula: see text], we calculate [Formula: see text]...

Physical Selection of Cartan Soft Breakings in a Broken SU (3) Yang–Mills Model

We revisit the broken-[Formula: see text] Yang–Mills model with a soft quadratic color deformation induced by the dimension-two operator [Formula: see text], previously studied for a constant source aligned along the color-3 direction. We extend the construction to a generic Cart...

Malaysia Factor Model: A Case for Uncoupling Fama-French Emerging Markets' Factors

The development of Islamic equity markets is a growing phenomenon that warrants the development of an asset pricing model that is able to accurately model returns. In this paper, we investigate whether the five-factor (5-factor) model is more suitable to compute expected returns...
