AIChE Journal, EarlyView.Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

Transversal String Topology and Invariants of Manifolds [PDF]
, 2011 Loop spaces have played a recurring and important role in mathematics - from closed geodesics in differential geometry to based loop spaces which play a central role in homotopy theory. The subject of string topology originating from the seminal paper by

Automated generative process synthesis via transformer‐based dual‐loop simulation and optimization
AIChE Journal, EarlyView.Abstract This study presents a novel framework for automated generative process synthesis, addressing the complexity of simultaneously optimizing discrete topologies and continuous operating variables. To overcome conventional superstructure limitations, we propose a dual‐loop architecture integrating generative transformers with rigorous process ...

Models and string topology [PDF]
This thesis concerns the study of string topology, a relatively new branch of algebraic topology. We begin with a survey of the background of string topology.

Instantons, Topological Strings, and Enumerative Geometry [PDF]
Advances in Mathematical Physics, 2010 We review and elaborate on certain aspects of the connections between instanton counting in maximally supersymmetric gauge theories and the computation of enumerative invariants of smooth varieties. We study in detail three instances of gauge theories in six, four, and two dimensions which naturally arise in the context of topological string theory on ...

GraphRAG for engineering diagrams: ChatP&ID enables LLM interaction with P&IDs
AIChE Journal, EarlyView.Abstract Piping and Instrumentation Diagrams (P&IDs) are central to process engineering workflows, yet extracting information from them remains a tedious and time‐consuming task. This work introduces ChatP&ID, a framework enabling natural‐language interaction with smart P&IDs through Graph Retrieval‐Augmented Generation (GraphRAG), to our knowledge ...

Generalized string topology operations [PDF]
, 2008 We show that the Chas-Sullivan loop product, a combination of the Pontrjagin product on the fiber and the intersection product on the base, makes sense on the total space homology of any fiberwise monoid E over a closed oriented manifold M.

A Novel Method to Balance and Reconfigure Series-Connected Battery Strings
Energies, 2016 Cell failure and imbalance are critical problems in battery storage systems, especially in series-connected battery strings. The reconfiguration function and the balancing function are both of great importance, but it is very challenging and problematic ...
