BeiDou Augmented Navigation from Low Earth Orbit Satellites

Currently, the Global Navigation Satellite System (GNSS) mainly uses the satellites in Medium Earth Orbit (MEO) to provide position, navigation, and timing (PNT) service.The weak navigation signals limit its usage in deep attenuation environments, and make it easy to interference and copyright by jammers or spoofers.Moreover, being far away to the

Key Synchronization Method Based on Negative Databases and Physical Channel State Characteristics of Wireless Sensor Network

Due to their inherent openness, wireless sensor networks (WSNs) are vulnerable to eavesdropping attacks.Addressing the issue of secure Internet Key Exchange (IKE) in the absence of reliable third parties like CA/PKI (Certificate Authority/Public Key Infrastructure) in WSNs, a novel key synchronization method named NDPCS-KS is proposed in the paper.

A 4q35.2 subtelomeric deletion identified in a screen of patients with co-morbid psychiatric illness and mental retardation

Abstract Background Cryptic structural abnormalities within the subtelomeric regions of chromosomes have been the focus of much recent research because of their discovery in a percentage of people with mental retardation (UK terminology: learning disability).These studies focused on subjects (largely children) with various severities of intellectua

Differential Dopamine D1 and D3 Receptor Modulation and Expression in the Spinal Cord of Two Mouse Models of Restless Legs Syndrome

Restless Legs Syndrome (RLS) is often and successfully treated with dopamine receptor agonists that target the inhibitory D3 receptor subtype, however there is no clinical evidence of a D3 receptor dysfunction in RLS patients.In contrast, genome-wide association studies in RLS patients Motor Hood have established that a mutation of the MEIS1 gene i

Study of Assimilation of Cored Wire into Liquid Steel Baths

Cored wire Motor Hood is a widespread technology used for performing additions into liquid metal baths as an alternative to bulk-additions.A laboratory-scale study was performed in which the kinetics of assimilation of cored wire in liquid steel baths were studied.An original dataset of positions of the wire/melt interface of cored wire as a functi
