While standard Transformer architectures (GPT, Claude) suffer from quadratic complexity O(N^2) during training and exploding Key-Value caches during generation, we introduce TUPOI — a foundational attention-free architecture that operates with strictly constant O(1) memory (64.00 KB) and multi-head Delta-KV associativ…
Abstract Hydroxypropyl chitosan (HPCS) is a water-soluble, cationic derivative of chitosan whose combination of hydrophilic substituents and residual charged and hydrophobic groups creates a unique landscape of interactions in aqueous media. Despite growing interest in chitosan-based materials, the fundamental solutio…
Heterogeneity in municipal solid waste (MSW) properties remains a major challenge for thermochemical processing applications in both energy recovery and recycling sectors. The inherently heterogeneous nature of waste directly affects its characteristics as feedstock, complicating process design, operational control, a…
The formation of tetracalcium aluminoferrite within the CaO-Al2O3-Fe2O3 system significantly influences clinker phase evolution and cement performance. The limited availability of high-grade Fe2O3 has encouraged the exploration of alternative iron-bearing materials, such as iron sand, for sustainable clinker productio…
Recent research in Illinois, USA, indicates that asphalt concrete (AC) in “extended-life” or “perpetual” pavement configurations, such as full-depth asphalt and AC over rubblized concrete, is subjected to low tensile strain levels in the field. While bottom-up fatigue cracking is rare in these structures, the increase…
Embedded memory dielectrics face two families of material-level bottlenecks whose microscopic origins are phase transitions: ferroelectric (FE)/antiferroelectric (AFE) HfO2-based memory suffers wake-up/fatigue from electric-field-induced phase transitions among Pca21/P42/nmc/Pbca; phase-change memory (PCM) suffers a t…
Ultra-high-performance concrete (UHPC) is prone to uncontrolled crack propagation and brittle failure, especially under fire events. Steel, polyethylene, and carbon fibers can halt thermal cracking from micro to macro levels, effectively enhancing the crack resistance and toughness of UHPC. Additionally, cenospheres a…
Abstract A simple, scientific method to prepare supported metal nanoparticles was proposed almost 50 years ago, which utilizes the protonation–deprotonation chemistry of the nascent hydroxyl groups that populate typical support surfaces. In aqueous solution, these can be protonated and so positively charged in the pH…
Complex surfaces exhibit hierarchical morphological organizations that cannot be fully described by conventional roughness parameters alone. In this study, a fractal–statistical framework is proposed to elucidate the substrate-controlled morphological evolution of 2,6-diphenyl anthracene (DPA) thin films deposited on…
SHMT2 (serine hydroxymethyltransferase 2) is a pivotal enzyme in cellular metabolism and is closely associated with the initiation and progression of malignant tumors, garnering significant attention in cancer research and therapy. Aberrant expression of SHMT2 has been observed in various cancers, correlating with tum…
Abstract Translating the solution-phase properties of colloidal nanocrystals into bulk porous monoliths requires gelation strategies that preserve the surface chemistry and electronic structure of the building blocks, a particular challenge for substoichiometric oxides whose function is tied to their oxygen vacancy po…
This paper develops a revised mathematical solution framework for the chemistry challenge "Can chemical imaging become noninvasive at true molecular resolution deep inside living tissue?". The proposed Deep-Molecular Imaging Conjunctive Gate (DMICG) was constructed after an earlier formulation failed or remained only…
Multidrug resistance (MDR) remains a central obstacle in cancer therapy, accounting for over 90% of cancer-related mortality. Although calcium overload has emerged as a promising anticancer strategy, its clinical translation is largely limited by insufficient tumor selectivity. Hydroxyapatite nanoparticles (HAPNs) pos…
Predicting how passive oxide films grow and break down is central to corrosion science and the long-term integrity of structural alloys, and the point defect model (PDM) is the standard kinetic description: a stiff, coupled system of Nernst–Planck, Poisson, and Butler–Volmer equations on a moving boundary; solving it…
ABSTRACT The performance of FeNC single atom catalysts (SACs) is significantly influenced by the porous architecture of their N‐doped carbon substrates. Although the pore structure of FeNC SACs has been widely investigated from a chemical methodology perspective, the role of synthesis process engineering has received…
Abstract Dysregulated calcium homeostasis is a hallmark of neurodegenerative disorders, such as Alzheimer’s, Parkinson’s, and Huntington’s diseases. In Alzheimer’s disease (AD), the aggregation of amyloid beta (Aβ) peptides at neuronal membranes is shown to be modulated by the presence of Ca2+ ions, yet the molecular…
ABSTRACT A hemicarcerand first reported by Quan and Cram in 1991 was prepared and characterized by X‐ray crystallography. It incorporates CoCp 2 + PF 6 − with an equilibrium constant of ~220 M −1 at 120°C and apparently is indefinitely stable at room temperature. This potential weakly coordinating cation's structure w…
Abstract Conventional petroleum-based food packaging plastics cause serious environmental pollution, driving demand for high-performance, fully biodegradable green packaging materials. Blends of poly(butylene adipate-co-terephthalate) (PBAT) and poly(propylene carbonate) (PPC) are promising alternatives for eco-friend…
ABSTRACT The rising burden of chronic refractory wounds demands materials that accelerate healing and enable precise microenvironment monitoring. Although smart dressings with flexible sensing show promise, current systems remain limited to single‐signal detection without therapeutic efficacy. Herein, we propose a mul…
This revised article addresses Q0169, 'What determines the onset of cavitation and nanobubble stability in chemically complex liquids?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Nanobubble Critical-Radius Stability Model, uses bubble…
