[PDF][PDF] Ants and reinforcement learning: A case study in routing in dynamic networks

D Subramanian, P Druschel, J Chen - IJCAI (2), 1997 - Citeseer
We investigate two new distributed routing algorithms for data networks based on simple
biological" ants" that explore the network and rapidly learn good routes, using a novel variation …

Correlation for boiling heat transfer to saturated fluids in convective flow

JC Chen - Industrial & engineering chemistry process design and …, 1966 - ACS Publications
T¡). The surface area required in the cooler is critically dependent on the ratio of these
supersaturations, so that the ratio may be considered a “coefficient of performance.” Prior to pilot …

Fast drop movements resulting from the phase change on a gradient surface

S Daniel, MK Chaudhury, JC Chen - Science, 2001 - science.org
The movement of liquid drops on a surface with a radial surface tension gradient is described
here. When saturated steam passes over a colder hydrophobic substrate, numerous water …

Direct methane activation by atomically thin platinum nanolayers on two-dimensional metal carbides

Z Li, Y Xiao, PR Chowdhury, Z Wu, T Ma, JZ Chen… - Nature Catalysis, 2021 - nature.com
Efficient and direct conversion of methane to value-added products has been a long-term
challenge in shale gas applications. Here, we show that atomically thin nanolayers of Pt with a …

A robust and scalable clustering algorithm for mixed type attributes in large database environment

T Chiu, DP Fang, J Chen, Y Wang, C Jeris - Proceedings of the seventh …, 2001 - dl.acm.org
Clustering is a widely used technique in data mining applications to discover patterns in the
underlying data. Most traditional clustering algorithms are limited to handling datasets that …

Moderating and mediating effects of team identification in regard to causal attributions and summary judgments following a game outcome

R Madrigal, J Chen - Journal of Sport Management, 2008 - journals.humankinetics.com
Fans’ causal attributions for a game outcome refer to their assessments of the underlying
reasons for why things turned out as they did. We investigate the extent to which team …

[HTML][HTML] Tau internalization is regulated by 6-O sulfation on heparan sulfate proteoglycans (HSPGs)

JN Rauch, JJ Chen, AW Sorum, GM Miller, T Sharf… - Scientific reports, 2018 - nature.com
The misfolding and accumulation of tau protein into intracellular aggregates known as
neurofibrillary tangles is a pathological hallmark of neurodegenerative diseases such as …

Transient hovering performance of hummingbirds under conditions of maximal loading

P Chai, JSC Chen, R Dudley - Journal of Experimental …, 1997 - journals.biologists.com
Maximal load-lifting capacities of six ruby-throated hummingbirds (Archilochus colubris)
were determined under conditions of burst performance. Mechanical power output under …

[HTML][HTML] LOX-1 augments oxLDL uptake by lysoPC-stimulated murine macrophages but is not required for oxLDL clearance from plasma

DF Schaeffer, M Riazy, KS Parhar, JH Chen… - Journal of lipid …, 2009 - ASBMB
Oxidized LDL (oxLDL) promotes lipid accumulation as well as growth and survival signaling
in macrophages. OxLDL uptake is mainly due to scavenger receptors SR-AI/II and CD36. …
