Search and Study of Marked Code Structures for a Spatially Distributed System of Small-Sized Airborne Radars

open access: yesSensors, 2023
When forming the radar situation of a terrain, in order to increase its information content and to extract useful information, multi-position spatially distributed systems for integrating multi-angle radar data established by small-sized UAV-based ...

Signals Intelligence System with Software-Defined Radio

open access: yesApplied Sciences, 2023
In this paper, we present the implementation of a system that identifies the modulation of complex radio signals. This is realized using an artificial intelligence model developed, trained, and integrated with Microsoft Azure cloud.

Metalloproteinases and the modulation of GH signaling [PDF]

open access: yesJournal of Endocrinology, 2002
The metzincin metalloproteinase, tumor necrosis factor-alpha-converting enzyme (TACE), also known as ADAM (a disintegrin and metalloproteinase) 17, has recently been identified as an important enzyme for cleavage of the GH receptor (GHR) and shedding of GH-binding protein (GHBP).

Diagnosis of Combination Faults in a Planetary Gearbox using a Modulation Signal Bispectrum based Sideband Estimator [PDF]

open access: yes, 2015
This paper presents a novel method for diagnosing combination faults in planetary gearboxes. Vibration signals measured on the gearbox housing exhibit complicated characteristics because of multiple modulations of concurrent excitation sources, signal ...

Design and Performance Analysis of Navigation Signal Based on OFDM

open access: yesApplied Sciences, 2022
This paper proposes a new navigation modulation based on orthogonal frequency division multiplexing (OFDM). We derived the autocorrelation function and power spectral density of the OFDM modulation.

Myocilin Is a Modulator of Wnt Signaling [PDF]

open access: yesMolecular and Cellular Biology, 2009
It is well documented that mutations in the MYOCILIN gene may lead to juvenile- and adult-onset primary open-angle glaucoma. However, the functions of wild-type myocilin are still not well understood. To study the functions of human myocilin and its two proteolytic fragments, these proteins were expressed in HEK293 cells.

Optimization of an avionic VCSEL-based optical link through large signal characterization [PDF]

open access: yes, 2008
Optical communication systems have been widely preferred for network communications, especially for Datacoms Local Area Network links. The optical technology is an excellent candidate for on-board systems due to the potential weight saving and EMC ...

ER Retention of Signaling Modules [PDF]

open access: yesDevelopmental Cell, 2005
A novel strategy for controlling developmental signaling pathways, which uses specific ER retention mechanisms, has emerged from several recent studies. A paper by Yamamoto et al. (2005) identifies a new protein termed Shisa that inhibits both Wnt- and FGF-signaling pathways during Xenopus gastrulation by mediating ER retention of the Wnt receptor ...

Limits on discrete modulated signals [PDF]

open access: yesIEEE Transactions on Signal Processing, 1997
We develop theorems of a general nature that apply to the analysis of AM-FM signals of the form a(m)exp [j/spl phi/(m)] or a(m) cos [/spl phi/(m)] and to their behavior both in linear systems and in simple nonlinear systems comprised of products of linear elements.
