Quantitative Multiplex Real-Time Reverse Transcriptase–Polymerase Chain Reaction with Fluorescent Probe Detection of Killer Immunoglobulin-Like Receptors, KIR2DL4/3DL3

open access: yesDiagnostics, 2020
(1) Background: KIR2DL4/KIR3DL3 are the framework genes present in all KIR haplotypes, with unique expression patterns being present only in women and CD56bright NK cells. KIR genes have a high degree of DNA sequence identity.

Performance Improvement of Iterative Multiuser Detection for Large Sparsely-Spread CDMA Systems by Spatial Coupling

open access: yes, 2014
Kudekar et al. proved that the belief-propagation (BP) performance for low-density parity check (LDPC) codes can be boosted up to the maximum-a-posteriori (MAP) performance by spatial coupling.

Generating functional analysis of CDMA detection dynamics [PDF]

open access: yes, 2005
We investigate the detection dynamics of the parallel interference canceller (PIC) for code-division multiple-access (CDMA) multiuser detection, applied to a randomly spread, fully syncronous base-band uncoded CDMA channel model with additive white ...

Dark Matter Constraints in Heterotic M-Theory with Five-Brane Dominance [PDF]

open access: yes, 2001
The phenomenological implications of the M-theory limit in which supersymmetry is broken by the auxiliary fields of five-brane moduli is investigated. Assuming that the lightest neutralino provides the dark matter in the universe, constraints on the ...

Limits of Detection of Gravimetric Signals on Earth [PDF]

open access: yesScientific Reports, 2018
AbstractGravimetry is a well-established tool to probe the deep Earth’s processes. Geophysical signals coming from the deep Earth, like the inner core free oscillations, have however never been detected. Challenging quests raise the question of the limits of detection of elusive signals at the Earth’s surface.

Statistics of gamma-ray point sources below the Fermi detection limit

open access: yes, 2011
An analytic relation between the statistics of photons in pixels and the number counts of multi-photon point sources is used to constrain the distribution of gamma-ray point sources below the Fermi detection limit at energies above 1 GeV and at latitudes

Strong Quantum Spin Correlations Observed in Atomic Spin Mixing

open access: yes, 2011
We have observed sub-Poissonian spin correlations generated by collisionally induced spin mixing in a spin-1 Bose-Einstein condensate. We measure a quantum noise reduction of -7 dB (-10 dB corrected for detection noise) below the standard quantum limit ...
