introduction: it is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. orexin plays an important role in modulation of pain and stress. considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.we evaluated the involvement of ...

A generic M-ary continuous phase modulation (CPM) scheme, with a modulation index of h = 1/M, can be modeled by a continuous-phase encoder (CPE) followed by a memoryless modulator (MM), where the CPE is linear over the ring of integers modulo M. By designing a channel encoder (CE), which is a convolutional encoder, to operate over the same ring of integers modulo M, the CE and the CPE can be co...

A generic M-ary continuous phase modulation (CPM) scheme, with a modulation index of h = 1/M, can be decomposed into a continuous-phase encoder (CPE) followed by a memoryless modulator (MM), where the CPE is linear over the ring of integers modulo M. By using a channel encoder (CE), which is a convolutional encoder, to operate over the same ring of integers modulo M, the CE and the CPE can be c...

We use a recent numerical security proof approach to calculate tight secure key rates in the presence of collective attacks for continuous-variable (CV) eight-state phase-shift keying (8PSK) protocol with heterodyne detection asymptotic limit. The results are compared achievable QPSK obtained same technique. Furthermore, we investigate influence radial postselection on rate and examine recently...

Single-source binary hybrid multilevel inverters with cascaded transformers have a bulky transformer connected to their main H-bridge cells in each phase. This bulky transformer has been eliminated in this work without any effect on operation and modulation strategies. The proposed topology has significant advantages from view point of dimensions and number of transformers, design of transforme...

We demonstrate theoretically and experimentally that the phase retardance and relative optic-axis orientation of a sample can be calculated without prior knowledge of the actual value of the phase modulation amplitude when using a polarization-sensitive optical coherence tomography system based on continuous polarization modulation (CPM-PS-OCT). We also demonstrate that the sample Jones matrix ...

introduction: the nucleus paragigantocellularis lateralis (lpgi) is involved in the descending pain modulation. the neurostreoid, 17β-estradiol found in the pgi nucleus and modulates nociception by binding to estrogen receptors and also by allosteric interaction with nmda receptors. in this study, the role of nmda receptors in the 17β-estradiol-induced pain modulation was investigated by assess...

Cross phase modulation (XPM) is known as the phenomenon that the variations of intensity of one optical signal can change the refractive index of the fiber (Kerr effects), and modulate the phase of other optical signals co-propagating in the same fiber .We compare the impact of Q-factor, BER and timing jitter due to cross-phase modulation (XPM) in a wavelength-divisionmultiplexed system for dif...

The analysis of optical pulse generation by phase modulation of narrowband continuous-wave light, and subsequent propagation through a group-delay-dispersion circuit, is usually performed in terms of the so-called bunching parameter. This heuristic approach does not provide theoretical support for the electrooptic flat-top-pulse generation reported recently. Here, we perform a waveform synthesi...

Spatial frequency separability is proposed as an attractive exploit for obtaining color halftone watermarking methods from monochrome clustered-dot halftone watermarking techniques. Detection of watermarks embedded in individual halftone channels is typically confounded by the cross-coupling between colorant halftone separations and scan RGB channels caused by the so-called “unwanted absorption...
