SAC-Net: Structure-Aware Collaborative Network for Graph Similarity Computation
Abstract Graph Similarity Computation (GSC) is a core task in graph analysis. However, current mainstream GNN-based similarity models still suffer from two fundamental bottlenecks. First, constrained by the inherent mechanism of recursive local aggregation, namely the 1-Weisfeile...

Triangle Sums, Peripheral Cycles, and Contractions for Orderable Cographic Matroids
For closed simplicial surface triangulations, this preprint proves a general triangle-rooted gluing theorem for compatible cographic orderings and an exact if-and-only-if criterion for triangle sums. It constructs infinite families of 3-connected regular non-graphic orderable cog...

Innate immunity provides a critical first line of defense against pathogens and homeostatic perturbations. Pattern recognition receptors detect these disruptions and initiate immune responses through multi-protein complex formation to drive inflammatory signaling and cell death p...

BACKGROUND: Rural immersion programs are commonly used to expose medical students to rural practice using curriculum-embedded placements. However, evidence regarding short-term, funded, voluntary, rural immersion placements that are not part of standard curricula-based training a...

The Internet as Precedent: Architectural Lessons for Federated Computing
This technical note examines the Internet as an architectural precedent for Federated Computing. The analogy lies in preserving local autonomy by making only the conditions required across boundaries explicit. It is not a proposal for a Federated Computing protocol stack, nor a d...

Abstract The spin ladder model is an important platform bridging one-dimensional and two-dimensional magnetic systems, with its physical properties modulated by geometric configuration. As such, the S = 1/2 two-leg antiferromagnetic spin ladder has attracted attention due to its...

MODERN METHODS OF TREATMENT OF PATIENTS WITH OBSTRUCTIVE JAUNDICE OF TUMOR ORIGIN
Objective: To evaluate the clinical significance of modern surgical and minimally invasive biliary decompression methods in patients with obstructive jaundice of tumor origin and to optimize treatment strategies. Materials and Methods: The treatment outcomes of 235 patients trea...

Abstract The variational quantum Eigensolver (VQE) provides a scalable route to molecular ground-state energies on near-term quantum hardware, but its accuracy degrades rapidly as system size grows because hardware-efficient ansätze cannot span the full correlation subspace. We...

Abstract Background Radioactively labeled somatostatin analogs (SSAs) are used in PET imaging of meningiomas due to the high expression of somatostatin receptor (SSTR) subtype 2. 18 F-labeled SSTR-tracers offer several economic and logistical advantages over 68 Ga-labeled tracers...

Imputing longitudinal PROM data at the item and score level in clinical trials
Abstract Background Missing data in patient-reported outcome measures (PROMs) can affect estimation accuracy and inferential validity, particularly under missing-at-random (MAR) mechanisms. Multiple imputation (MI) is commonly recommended, but the relative performance of item-lev...

Abstract Background Intraoperative hypotension is a common occurrence during general anaesthesia that has consistently been associated with perioperative organ injury. While international consensus guidelines increasingly advocate for maintaining absolute mean arterial pressure t...

Error Indicators and Adaptivity for a Least-Squares Method Applied to the Monge-Ampère Equation
Abstract We introduce novel a posteriori error indicators for a nonlinear least-squares solver for smooth solutions of the Monge-Ampère equation on convex polygonal domains in $$\mathbb {R}^2$$ R 2 . The theoretical analysis is carried out for smooth solutions. At each iteration,...

Background Smoldering in forest litters is prone to transition to flaming under dry and windy conditions. Most studies focus on smoldering-to-flaming (StF) transition under steady wind conditions, however, a knowledge gap persists regarding periodic wind oscillations in wildfires...

Abstract Background Hoxc13 is a critical transcription factor that regulates the expression of hair keratin genes. Our previous study showed that during mammalian evolution, the Hoxc13 protein acquired a characteristic polyglycine repeat (polyG) insertion. This insertion distingu...

We present a fully covariant, scale-dependent disformal coupling within the dark sector (SD-DDM) designed to simultaneously resolve the Hubble (H0) and clustering (S8) tensions. By strictly confining the Bekenstein disformal transformation to Cold Dark Matter (CDM) and preserving...

Abstract Three rare-earth-embedded phosphotungstates with a dimeric sandwich structure containing two types of building blocks (BBs) [NH2(CH3)2]11H[RE(P2W17O61)(W5O18H)]·9H2O [RE = Dy3+ (1), Er3+ (2), Pr3+ (3)] have been synthesized via a one-pot self-assembly strategy. A distinc...
