Adaptive Tracking of High-Maneuvering Targets Based on Multi-Feature Fusion Trajectory Clustering: LPI’s Purpose

open access: yesSensors, 2022
Since the passive sensor has the property that it does not radiate signals, the use of passive sensors for target tracking is beneficial to improve the low probability of intercept (LPI) performance of the combat platform.

Physical-Layer Security with Multiuser Scheduling in Cognitive Radio Networks

open access: yes, 2013
In this paper, we consider a cognitive radio network that consists of one cognitive base station (CBS) and multiple cognitive users (CUs) in the presence of multiple eavesdroppers, where CUs transmit their data packets to CBS under a primary user's ...

Inhibitory control as a mediator of bidirectional effects between early oppositional behavior and maternal depression. [PDF]

open access: yes, 2014
Maternal depression is an established risk factor for child conduct problems, but relatively few studies have tested whether children's behavioral problems exacerbate mothers' depression or whether other child behavioral characteristics (e.g., self ...

Chosen Issues of Military Radar Protection Against Antiradiation Missiles [PDF]

open access: yesProblemy Mechatroniki, 2014
The paper deals with the concept of suppression of enemy air defence with antiradiation missiles (ARM). ARM performance metrics and parameters are presented and compared. Some Anti-ARM techniques are discussed, i.e.

Reliability-Security in Wireless-Powered Cooperative Network with Friendly Jammer

open access: yesAdvances in Electrical and Electronic Engineering, 2022
In this paper, we study the Outage Probability (OP) and the Intercept Probability (IP) of Wireless-Powered Cooperative Networks (WPCNs) in the presence of a malicious eavesdropper and a friendly jammer.

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Survival probability in diffractive Higgs production in high density QCD

open access: yes, 2007
In this paper, the contribution of hard processes described by the BFKL pomeron exchange, is taken into account by calculating the first enhanced diagram. The survival probability is estimated, using the ratio of the first enhanced diagram and the single

Bias of Maximum-Likelihood estimates in logistic and Cox regression models: A comparative simulation study [PDF]

open access: yes, 2003
Parameter estimates of logistic and Cox regression models are biased for finite samples. In a simulation study we investigated for both models the behaviour of the bias in relation to sample size and further parameters.

Shared Genetic Effects and Antagonistic Pleiotropy Between Multiple Sclerosis and Common Cancers

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Epidemiologic studies have reported inconsistent altered cancer risk in individuals with multiple sclerosis (MS). Factors such as immune dysregulation, comorbidities, and disease‐modifying therapies may contribute to this variability.
