Cold start performance analysis of PEMFC with different assisted heating strategies
Case Studies in Thermal EngineeringLarge-scale use of proton exchange membrane fuel cell (PEMFC) is restricted by the challenge of cold start. A three-dimensional, transient, multiphase flow cold-start model is established to investigate the effects of different assisted heating ...

Deep Pairwise Hashing for Cold-start Recommendation [PDF]
IEEE Transactions on Knowledge and Data Engineering, 2020 Recommendation efficiency and data sparsity problems have been regarded as two challenges of improving performance for online recommendation. Most of the previous related work focus on improving recommendation accuracy instead of efficiency. In this paper, we propose a Deep Pairwise Hashing (DPH) to map users and items to binary vectors in Hamming ...

Transferable Fairness for Cold-Start Recommendation
CoRR, 2023 With the increasing use and impact of recommender systems in our daily lives, how to achieve fairness in recommendation has become an important problem. Previous works on fairness-aware recommendation mainly focus on a predefined set of (usually warm-start) users. However, recommender systems often face more challenging fairness issues for new users or

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Improving Cold Start Stereotype-Based Recommendation Using Deep Learning
IEEE Access, 2023 Recommendation engines constitute a key component of many online platforms. One of the most challenging problems facing a recommender system is that of cold start, namely the recommendation of items from the catalogue to a new unknown user, or the ...

Modeling and Analysis of Polymer Electrolyte Fuel Cell Cold-Start
, 2010 In this paper, we develop a model to investigate the cold-start operation of polymer electrolyte fuel cell (PEFC). The model describes the electrochemical kinetics, heat/mass transport, and solid water formation in polymer electrolyte fuel cell (PEFC ...

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
