Wireless Sensor Networks (WSNs) are deployed for monitoring in a range of critical domains (e.g., health care, military, critical infrastructure). Accordingly, these WSNs should be resilient to attacks. The current approach to defending against malicious threats is to develop and deploy a specific defense mechanism for a specific attack. However, the problem with this traditional approach to de...

We present the discovery and characterisation of an eclipsing binary identified by Next Generation Transit Survey in $\sim$115 Myr old Blanco 1 open cluster. NGTS J0002-29 comprises three M dwarfs: a short-period companion wider orbit. This system is first well-characterised, low-mass 1. With low mass ratio, tertiary components that straddle fully convective boundary, it important benchmark sys...

Soybean plants (Glycine max var. Ransom) were grown at light intensities of 850 and 250 mueinsteins m(-2) sec(-1) of photosynthetically active radiation. A group of plants was shifted from each environment into the other environment 24 hours before the beginning of the experiment. Net photosynthetic rates and stomatal conductances were measured at 2,000 and 100 mueinsteins m(-2) sec(-1) photosy...

the potential of near infrared reflectance spectroscopy (nirs) as a fast method to predict the crude protein (cp) and moisture (m) content in fishmeal by scanning spectra between 1000 and 2500 nm using multivariate regression technique based on partial least squares (pls) was evaluated. the coefficient of determination in calibration (r2c) and standard error of calibration (sec) were 0.95 and 1...

Abstract Neuromagnetic responses were recorded to frequent "standard tones of l000 Hz and to infrequent 1100-Hz "deviant" tones with a 24-channel planar SQUID gradiometer. Stimuli were presented at constant interstimulus intervals (ISIs) ranging from 0.75 to 12 sec. The standards evoked a prominent 100-msec response, N100m, which increased in amplitude with increasing ISI. N100m could be dissoc...

The long-term hemodynamic effects of a high dietary sodium intake were studied in 10 young normal subjects. After a 4-day diet of 10 mEq of sodium and 60 mEq of potassium per day the mean arterial blood pressure (MAP) was 82.3 ± 15.1 mm Hg, the cardiac index (CI) was 2.32 ± 0.69 liter/min/m, and total peripheral resistance (TPR) was 1778 ± 947 dyne sec cm". After 4 to 6 days of 200 mEq of sodiu...

BACKGROUND AND OBJECTIVES The factors related to the progression of mild aortic stenosis (AS) remain unknown. We wanted to evaluate the long-term outcomes and predictors of echocardiographic progression in patients with mild AS. SUBJECTS AND METHODS We prospectively included 103 consecutive asymptomatic patients (62.1±11.9 years, 31 males) with mild AS. Mild AS was defined as aortic valve (AV...
