Polycomb Responds to Low Levels of Transcription
Cell Reports, 2017 How is Polycomb (Pc), a eukaryotic negative regulator of transcription, targeted to specific mammalian genes? Our genome-wide analysis of the Pc mark H3K27me3 in murine cells revealed that Pc is preferentially associated with CpG island promoters of ...

Polarization filtering for automatic picking of seismic data and improved converted phase detection [PDF]
, 2001 Data-adaptive polarization filtering is used to improve the detection of converted seismic phases. Both direct waves and mode-converted PS and SP arrivals may be more easily picked on the filtered records. An autopicking routine is applied that cuts the

Novel Real-Time Facial Wound Recovery Synthesis Using Subsurface Scattering
The Scientific World Journal, 2014 We propose a wound recovery synthesis model that illustrates the appearance of a wound healing on a 3-dimensional (3D) face. The H3 model is used to determine the size of the recovering wound.

Safeguarding cross-silo federated learning with local differential privacy
Digital Communications and Networks, 2022 Federated Learning (FL) is a new computing paradigm in privacy-preserving Machine Learning (ML), where the ML model is trained in a decentralized manner by the clients, preventing the server from directly accessing privacy-sensitive data from the clients.

Estimated energy and emissions impacts of pumping Pacific Ocean water to Great Salt Lake
Environmental Research Communications, 2023 Great Salt Lake in Utah, USA, has receded in recent years. Among many options proposed to augment inflows is a pipeline from the Pacific Ocean. We estimate a lower bound for the ongoing energy requirements, assuming one-third of the recommended ...
