A generative model for sparse, evolving digraphs [PDF]
, 2017 Generating graphs that are similar to real ones is an open problem, while the similarity notion is quite elusive and hard to formalize. In this paper, we focus on sparse digraphs and propose SDG, an algorithm that aims at generating graphs similar to ...

The BCS theory of q-deformed nucleon pairs - qBCS
, 2000 We construct a coherent state of q-deformed zero coupled nucleon pairs distributed in several single-particle orbits. Using a variational approach, the set of equations of qBCS theory, to be solved self consistently for occupation probabilities, gap ...

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis
Advanced Materials, EarlyView.We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...
