Signal processing in passive radar with multi-user MIMO-OFDM signal

open access: yesEURASIP Journal on Advances in Signal Processing, 2022
In this paper, we propose a signal processing method in passive radar using the multi-user (MU) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) signal as the illuminator of opportunity.

Effects of the differences in mental states on the mirror system activities when observing hand actions

open access: yesJournal of Physiological Anthropology, 2019
Background It is known that the activities of the mirror system are related to imitation and understanding of the intention of an action. It has been reported that the activity of the mirror system is higher for observations for imitating and ...

Suppressing Proton Decay by Cancellation in S_4 Flavor Symmetric Extra U(1) Model [PDF]

open access: yes, 2012
We consider proton stability based on E_6 inspired extra U(1) model with S_4 flavor symmetry. In this model, a long life time of proton is realized by the flavor symmetry.

Magnetic disorder and gap symmetry in optimally electron doped Sr(Fe, Co)$_2$As$_2$ superconductor

open access: yes, 2017
We investigate the magnetic pair-breaking due to Mn impurities in the optimally electron doped Sr(Fe$_{0.88} $Co$_{0.12} $)$_{2} $As$_2 $ superconductor to deduce the symmetry of the superconducting order parameter.

EEG theta and Mu oscillations during perception of human and robot actions. [PDF]

open access: yes, 2013
The perception of others' actions supports important skills such as communication, intention understanding, and empathy. Are mechanisms of action processing in the human brain specifically tuned to process biological agents?

Effects of cyclosporin on cholesterol 27-hydroxylation and LDL receptor activity in HepG2 cells.

open access: yesJournal of Lipid Research, 1996
The hypothesis that mitochondrial sterol 27-hydroxylase plays a role in the sterol-mediated down-regulation of LDL receptor activity was evaluated in HepG2 cells. 27-Hydroxycholesterol was found to be more potent at suppressing LDL receptor activity than

Observation of the suppressed decay $\Lambda \ _b \ ^0 \to p \pi^- \mu^+ \mu^-$

open access: yes, 2017
The suppressed decay $\Lambda \ _b \ ^0 \to p \pi^- \mu^+ \mu^-$, excluding the $J/ \psi$ and $\psi(2S) \to \mu^+ \mu^-$ resonances, is observed for the first time with a significance of 5.5 standard deviations. The analysis is performed with proton-proton collision data corresponding to an integrated luminosity of 3 $fb^{−1}$ collected with the LHCb ...

Proton Decay, Neutrino Oscillations And Other Consequences From Supersymmetric SU(6) With Pseudo-Goldstone Higgs

open access: yes, 1999
We suggest a new mechanism for naturally suppressing dimension five baryon number violating in supersymmetric SU(5+N) (N=0, 1,...) GUTs. The mechanism is realized through suppression of qqT type couplings, and is implemented by introducing new `matter ...

Probing the theoretical description of central exclusive production [PDF]

open access: yes, 2010
We investigate the theoretical description of the central exclusive production process, $h_1 + h_2 \to h_1+X+h_2$. Taking Higgs production as an example, we compute the subset of next-to-leading order corrections sensitive to the Sudakov factor appearing
