On the Detection of Direct Directed Information Flow in fMRI
IEEE Journal of Selected Topics in Signal Processing, 2008To infer interactions from functional magnetic resonance imaging (fMRI) data, structural equation modeling (SEM) as well as dynamic causal modeling (DCM) has been suggested. Directed partial correlation (dPC) is a measure which detects Granger causality in multivariate systems. To demonstrate the strengths as well as the limitations of directed partial

Direct Detection of the Vasopressin Precursor
Endocrine Research Communications, 1980Cysteine-rich proteins were isolated from the hypothalamo-neurohypophyseal tract of dogs by high performance molecular weight chromatography. Trypsin digestion of these proteins produced a low molecular weight (LMW) peptide which was identified, by chemical and immunological assays, as (Arg8) vasopressin.

Component Detection in Directed Networks
Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management, 2014Community detection has been one of the fundamental problems in network analysis. Results from community detection (for example, grouping of products by latent category) can also serve as information nuggets to other business applications, such as product recommendation or taxonomy building.

Advanced Direct Detection Schemes
Optical Fiber Communication Conference (OFC) 2021, 2021In this tutorial, we review various advanced direct detection schemes to bridge the gap between conventional direct and coherent detection. We show such schemes may play an important role for future ultrahigh-speed short-reach applications.

Decoupled direction finding: detection
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181), 2002Antenna arrays are likely to be an important feature of future mobile communication systems. With an antenna array, mobile users can be separated by a spatial filtering procedure allowing several users on the same carrier frequency. The uplink part (mobile to base) not only can, but is better solved without using any spatial knowledge in terms of ...

Optical Fiber Communication Conference, 2014
In this paper we review the prior works on DDO-OFDM systems, including the traditional DDO-OFDM that utilizes single band and single polarization, the multiband DDOOFDM superchannel, and the dual-polarization (PDM) DDO-OFDM.

Once we understood how dark matter can be produced in the early Universe, from the inflationary phase to the thermal one, passing through the reheating process, it is time to question the possibility to detect this dark component largely present in our galaxy.

Directions in Incident Detection and Response
IEEE Security & Privacy Magazine, 2011Richard Bejtlich leads a conversation on how incident detection and response (IDR) teams' focus on detecting and preventing attacks has moved from targeting OSs to unauthorized-access-application functionality and data. He discusses why this makes IDR so much more difficult and what these new targets mean for IDR. Department editors Gunnar Peterson and

Directional Feature Detection and Correspondence
2005A method is proposed to detect useful directional feature points other than corner points considering that the number of corner points may not be sufficient in a scene. This is achieved by directional analysis of properties of image points by virtue of the proposed gradient operators with different direction topologies.
