Pricing of perpetual American options in diffusion models with progressively enlarged filtrations

We study the problems of pricing of perpetual American options in one-dimensional positive diffusion models of financial markets with progressively enlarged Brownian reference filtrations. It is assumed that the reward processes represent integrals of discounted continuous piecew...

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...

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...

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...

Dynamic Stress and Emotional Health Management Platform Based on the Fusion of Multimodal Music Emotion Perception and Wearable Physiological Signals

In order to solve the problems that existing wearable emotion monitoring methods have in continuously describing the stress assessment process and lack the ability of dynamic emotion regulation and feedback, this study proposes Multimodal Stress-aware Cross-modal Emotion Network...

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...

Precision-Aware Variable Bit Processing Elements for Hardware-Efficient Systolic Array Designs

Systolic arrays (SAs) have emerged as prominent hardware accelerators for matrix operations in deep learning, while floating point number formats enable precision control across computational domains. Approximate computing involves trading precision for improved performance in ap...

Probing mass-radius and tidal properties of strange stars and GW190814 with the CFL phase equation of state

We propose a new class of compact star models by adopting the Durgapal IV metric potential for the temporal component g tt , together with a physically motivated anisotropic pressure distribution. To identify the conditions under which the interior matter configuration replicates...

Privacy-Constrained Distributionally Robust Detection and Collaborative Attribution of LLM-Generated Text

With the widespread use of large language models, distinguishing human-written text from LLM-generated text has become increasingly important for content authenticity, academic integrity, and digital forensics. However, existing detectors remain vulnerable to paraphrase attacks,...

Reframing of information geometry via symmetric teleparallel gravity

Information geometry has traditionally been formulated within the framework of Riemannian geometry and dual affine connections. This work aims to reframe the foundational structure of information geometry by introducing the geometric machinery of symmetric teleparallel gravity. B...

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-...

Characteristics and parameterisation of spallation neutrons

The present study investigates neutron generation by spallation with an emphasis on optimisation and parameterisation of target geometry and examines its implications for accelerator-driven subcritical reactors (ADSRs) and other advanced neutron sources. We investigate neutron yi...

2025 AHA/ACC blood pressure guideline and HEARTS 2.0: implications for the future evolution of integrated cardiovascular–kidney–metabolic care in the Americas

ABSTRACT Hypertension is the leading modifiable risk factor for cardiovascular disease. In 2025, two major evidence-based frameworks evolved in parallel: HEARTS 2.0, an implementation-oriented clinical pathway for integrated cardiovascular–kidney–metabolic (CKM) care through prim...

Thermal Architecture of Ternary Magnetized Casson Nanofluids within 2D and 3D Dimpled Enclosures with Rotational Cylindrical Obstruction

Compact and high-efficiency thermal systems are the need of innovative heat transfer enhancement mechanisms. Dimpled enclosures are important due to their ability to intensify flow recirculation, disrupt thermal boundary layers, and promote enhanced convective transport. This stu...

Ensemble Prediction Framework for Abrasive Aqua-Jet Cutting of TiAFL with RSM Integration

This work comprehensively assesses the machinability of basalt/flax fibre laminates that were compressed-molded with titanium and then cut via abrasive aqua-jet cutting (AAJC). The focus is on four key AAJC parameters including; abrasive pressure, cutting speed, distance from noz...
