Secure Computation in Decentralized Systems by Zyskind, Guy

“…The research employs Secure Multiparty Computation (MPC) techniques to address these issues, demonstrating how MPC, which already shares a similar distributed trust threat model, can enhance privacy in decentralized systems. More specifically, this thesis focuses on the following key areas in decentralized systems: Access Control Mechanisms and Confidential Smart Contracts: The thesis begins by exploring access control mechanisms on blockchains, and from that builds up to the concept of confidential smart contracts -- arbitrary programs that execute both correctly and privately. …”

Nanoscale Origins of Thermal Transport Phenomena for Hybrid Layered Perovskites by Dahod, Nabeel S.

“…This experimental study reveals that even in terms of their thermal transport pathways, 2D LHPs can be treated as composite materials. Specifically, lead bromide 2D LHPs exhibit structure-property relationships characteristic of ballistic phonon transport within isolated subphases and diffuse scattering at the organic-inorganic interfaces between layers. …”

Synthesis of Au@Pd core/shell nanomaterials for high-performance ethanol oxidation reactions by Xu, Weichang

“…When the concentration of PdCl2 was reduced to 2.5 mM, the Au surface would be partially coated with Pd domains and the CV scan could facilitate the physical movement of Pd atoms to realize full coverage of the exposed Au surface. The mass-specific current of the Pd coated AuNW nickel foam electrode on ethanol oxidation can be enhanced to 6464 A/g, over two times higher than that of typical electrochemical deposited one. …”

Towards automated damage detection for in-situ remanufacturing by Nguyen, Keith Wei Liang

“…A laborious remanufacturing process that benefits from automation is the inspection process, specifically damage detection and classification. It is preferable to automate damage detection from 3D data over 2D images, as the 3D data of the detected damage region is required for the hybrid manufacturing process in the downstream repair procedure. …”

Direct and indirect effects of fire on microbial communities in a pyrodiverse dry-sclerophyll forest by Bowd, Elle J., Egidi, Eleonora, Lindenmayer, David B., Wardle, David A., Kardol, Paul, Cary, Geoffrey J., Foster, Claire

“…Our findings indicate that predicted increases in the frequency of fire may select for specific microbial communities directly and indirectly through ecological interactions, which may have functional implications for plants (increase in pathogens, decrease in symbionts), decomposition rates (declines in Actinobacteriota and Acidobacteriota) and carbon storage (decrease in ectomycorrhizal fungi). …”

Power system feasibility and flexibility analysis for enlarging renewable exploitation under high uncertainties by Weng, Yu

“…Next, a framework for feasibility and flexibility analysis is established for both peer-to-peer energy trading and Transmission System Operator-Distribution System Operator (TSO-DSO) coordination to promote renewable usage while ensuring system safety. Specifically, admissible renewable injection regions that ensure operational compliance are constructed to facilitate individual participators and also assist system operators in being aware of vulnerable sub-systems. …”

Counterfactual explanations for machine learning models on heterogeneous data by Wang, Yongjie

“…To address this gap, we propose an efficient and effective attack method that can extract the pretrained model through counterfactual explanations (CFs). Specifically, our method treats CFs as common queries to find counterfactual explanations of counterfactual explanations (CCFs) and then trains a substitute model using pairs of CFs and CCFs. …”
