On Estimating the QSO Transmission Power Spectrum [PDF]
, 2000 We present new methods to minimize the systematic and random errors for measuring the transmission power spectrum from the Lyman-alpha forest. Sources of systematic errors explored include metal line contamination and continuum-fitting.

GCFR: graph contrastive fault representation for robust diagnosis in power communication networks
Scientific ReportsThis work addresses fault diagnosis in power communication networks (PCNs) under three practical challenges–limited labels, evolving topology, and noisy alarms–by proposing GCFR, a graph-contrastive fault representation framework. GCFR learns robust node

Long-Range Response to Transmission Line Disturbances in DC Electricity Grids
, 2014 We consider a DC electricity grid composed of transmission lines connecting power generators and consumers at its nodes. The DC grid is described by nonlinear equations derived from Kirchhoff's law.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

A Cross-layer Perspective on Energy Harvesting Aided Green Communications over Fading Channels
, 2013 We consider the power allocation of the physical layer and the buffer delay of the upper application layer in energy harvesting green networks. The total power required for reliable transmission includes the transmission power and the circuit power.

The Effect of Annealing on the Structure and Electric Performance of Polypropylene Films
International Journal of Polymer Science, 2022 Biaxially oriented polypropylene (BOPP) and uniaxially oriented polypropylene (UOPP) films were annealed. The effect of annealing temperature (Ta) on dielectric strength was studied.
