Thu 21 Aug 12:45: GNN-ACLP: Graph Neural Networks Based Analog Circuit Link Prediction https://drive.google.com/file/d/1W_VPanXTm3I6oWFV2xhm81H2egEViXhI/view?usp=sharing
Circuit link prediction identifying missing component connections from incomplete netlists is crucial in analog circuit design automation. However, existing methods face three main challenges: 1) Insufficient use of topological patterns in circuit graphs reduces prediction accuracy; 2) Data scarcity due to the complexity of annotations hinders model generalization; 3) Limited adaptability to various netlist formats. We propose GNN -ACLP, a graph neural networks (GNNs) based method featuring three innovations to tackle these challenges. First, we introduce the SEAL (learning from Subgraphs, Embeddings, and Attributes for Link prediction) framework and achieve port-level accuracy in circuit link prediction. Second, we propose Netlist Babel Fish, a netlist format conversion tool leveraging retrieval-augmented generation (RAG) with a large language model (LLM) to improve the compatibility of netlist formats. Finally, we construct SpiceNetlist, a comprehensive dataset that contains 775 annotated circuits across 10 different component classes. Experiments demonstrate accuracy improvements of 16.08% on SpiceNetlist, 11.38% on Image2Net, and 16.01% on Masala-CHAI compared to the baseline in intra-dataset evaluation, while maintaining accuracy from 92.05% to 99.07% in cross-dataset evaluation, exhibiting robust feature transfer capabilities.

Tue 26 Aug 16:00: Direct brain stimulation modulate physiology and behaviour in humans.
Direct brain electrical brain stimulation offers a causal window on human brain function and a route to therapy. This talk contrasts open-loop perturbation, single pulses and short trains used to map effective connectivity and state dependence across wake, sleep and anaesthesia, with closed-loop paradigms that detect neural features in intracranial EEG in real time to trigger stimulation. I’ll show how closed-loop experiments can adjust stimulation based on estimated cognitive state, producing rapid changes in cortical dynamics and measurable effects on behaviour during ongoing tasks. I’ll also discuss high-frequency oscillations and ripples as candidate biomarkers for targeting, and outline opportunities and limits for translating these methods to precision neuromodulation in humans.
The Host for this talk is Tristan Bekinschtein, tb419@cam.ac.uk.

Self‐Stratifying Colored Radiative Cooling Paints Through Narrow‐Band Color Preservation Scheme
This work introduces an easy-fabrication and self-stratifying paint recipe that forms an absorptionscattering dual-layer structure, systematically preserving color while enabling subambient daytime radiative cooling. All colored paints exhibit outstanding subambient cooling potential (>90% solar refletance and 0.94 sky window emissivity), and the coolest black paint achieves exceptionally high solar reflectance (∼46%).
Abstract
Although significant energy-saving potential of passive daytime radiative cooling has led to diffusively white or reflective surfaces, achieving coloration expands their application for both aesthetic and functional purposes. However, it presents huge technical challenges in scalable processing. This work presents a novel and general self-stratifying approach for creating radiative cooling paints with various colors using selected narrow-band absorption dyes. Applied as a single coat, these paints self-assemble into an absorption-scattering dual-layer structure that efficiently displays color while minimizing light absorption. Three base colors (cyan, magenta, and yellow) are demonstrated to provide full daytime subambient cooling, achieving 93% solar reflectance and 0.94 sky window emissivity. One newly developed black paint achieves 46.3% solar reflectance and a temperature drop of up to 25 °C, outperforming commercial counterparts. A purple radiative cooling paint (mixed dyes) demonstrates the color customization potential within the CMYK space, addressing the dilemma between color and cooling for colored radiative cooling paints. The mechanical and surface properties, characterized by abrasion, adhesion, and contact angle tests, are on par with or surpassing commercial products. This unique self-stratifying mechanism enhances surface properties and provides new insights for developing high-volume loading paints and water-harvesting coatings without increasing fabrication complexity.

Cation‐Selective Defects Engineering in A‐Site Ordered Layered Perovskites for High‐Performance Reversible Protonic Ceramic Cells
A cation-selective defects strategy is proposed to decouple and optimize activity and durability of A-site ordered layered perovskites air electrode for reversible protonic ceramic cells (RPCCs). A specific cations-deficient Pr(Ba0.5Sr0.5)0.95Co1.5Fe0.5O5+δ displays superior activity and stability when used as an RPCCs air electrode, accelerating its commercialization.
Abstract
Reversible protonic ceramic cells facilitate efficient chemical-electrical energy interconversion, advancing renewable energy utilization. Commercial viability, however, demands intermediate-to-low temperatures (ILT, 400–600 °C) operation, currently constrained by air electrode performance. A-site ordered layered perovskite PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) promises, yet faces activity and stability issues at ILT. Cation defects effectively tune defect structures in simple perovskites, boosting electrochemical performance, but their specific effects in A-site ordered perovskites with dual A-site environments remain unexplored. Here, A-site cation-selective defects are engineered to tune PBSCF's performance, with Pr-deficient (Pr0.95Ba0.5Sr0.5Co1.5Fe0.5O5+δ, p-PBSCF) and Ba/Sr-deficient (Pr(Ba0.5Sr0.5)0.95Co1.5Fe0.5O5+δ, bs-PBSCF) variants revealing distinct defects-performance relationships. Pr defects weaken Co─O covalency to activate Co sites, enhancing oxygen electrocatalytic activity. Concurrently, it lowers oxygen vacancy concentration, inhibiting hydration-induced lattice expansion. This stabilizes Ba─O/Sr─O bonds and mitigates Ba/Sr segregation, enhancing stability. However, the reduced oxygen vacancy concentration inhibits the material's hydration, lowering proton conduction and thus restricting activity enhancement. In contrast, Ba/Sr defects not only weaken Co─O covalency to activate Co sites, but also increase oxygen vacancy concentration, promoting proton and oxygen-ion transport, thereby significantly enhancing electrode activity. Furthermore, despite increased hydration, bs-PBSCF's larger-radius cation defects yield a smaller unit cell versus p-PBSCF, further strengthening Ba─O/Sr─O bonds and inhibiting Ba/Sr segregation, thus leading to superior stability.
Role of Precursor Miscibility in Area‐Selective Atomic Layer Deposition
This study investigates how the chemical structure of alumina precursors affects their interaction with benzenethiol inhibitor layers on Cu surfaces during area-selective atomic layer deposition (AS-ALD). It reveals that ligand-dependent miscibility and Lewis acidity govern precursor infiltration and degradation of the inhibitor, leading to selectivity loss. The work introduces a new mechanism for selectivity failure in AS-ALD processes.
Abstract
Area-selective atomic layer deposition (AS-ALD) is of increasing importance in nanostructure fabrication, and precursor selection is critical to realizing a successful process. This work explores the role of the precursor in achieving AS-ALD of Al2O3 on a dielectric (SiO2) in the presence of a metal (Cu/CuOx). Four different precursors—dimethylaluminum isopropoxide (DMAI), trimethylaluminum (TMA), triethylaluminum (TEA), and triisobutylaluminum (TIBA)—are tested against a benzenethiol (BT) inhibitor. BT forms monolayers on Cu, whereas on CuOx it forms a thick crystalline multilayer composed of 1D-coordination polymers of Cu-thiolate (CuBT). This work observes that DMAI provides exceptional selectivity: 22 nm of Al2O3 can be deposited on patterned substrates with 99.9% selectivity, and in the case of thick CuBT can achieve excellent pattern transfer on nanoscale patterns with well-defined material interfaces. In contrast, none of the alkylaluminum precursors show significant selectivity, a result attributed to their miscibility in the CuBT multilayer leading to its degradation. This work proposes that the miscibility of the alkylaluminum precursors depends on ligand length and structure. The results show that the ligand-dependent miscibility and subsequent degradation of CuBT impact the location of Al2O3 nucleation. This study highlights new considerations for AS-ALD process design to achieve high selectivity.
