BACKGROUND AND PURPOSE Transient or minor ischemic stroke is associated with an early risk of deterioration. Baseline perfusion-diffusion mismatch may predict clinical deterioration and infarct growth in this population. METHODS High-risk transient ischemic attack and minor stroke (National Institutes of Health Stroke Scale ≤3) subjects were prospectively enrolled and imaged with MRI within 2...

Leaf area index (LAI) is a key input in models describing biosphere processes and has widely been used in monitoring crop growth and in yield estimation. In this study, a hybrid inversion method is developed to estimate LAI values of winter oilseed rape during growth using high spatial resolution optical satellite data covering a test site located in southeast China. Based on PROSAIL (coupling ...

(3) The error is normally of the order of 1 percent a t the higher levels (5,000-20,000 feet) of an average curve. (4) When applied to the upper levels of a very stable curve (e. g. one featuring an extensive inversion), the rule leads to an overestimation of the height which may mount , to 4 percent or more in an extreme case. The formula i s least accurate when applied to the upper levels of ...

The slope of the Treasury yield curve has often been cited as a leading economic indicator, with inversion of the curve being thought of as a harbinger of a recession. In this paper, I consider a number of probit models using the yield curve to forecast recessions. Models that use both the level of the federal funds rate and the term spread give better insample fit, and better out-of-sample pre...

We study the red-optical photometry of ultra-hot Jupiter WASP-121 b as observed by Transiting Exoplanet Survey Satellite (TESS) and model its atmosphere through a radiative transfer simulation. Given short orbital period $\sim1.275$ days, inflated state bright host star, is exceptionally favorable for detailed atmospheric characterization. Towards this purpose, we use \texttt{allesfitter} to ch...

This paper presents an efficient crypto processor architecture for key agreement using ECDH (Elliptic-curve Diffie Hellman) protocol over . The composition of our key-agreement is expressed in consisting the following: (i) Elliptic-curve Point Multiplication public generation (DESIGN-I) and (ii) integration DESIGN-I with two additional routing multiplexers a controller shared (DESIGN-II). arith...

The negation map can be used to speed up the computation of elliptic curve discrete logarithms using either the baby-step giant-step algorithm (BSGS) or Pollard rho. Montgomery’s simultaneous modular inversion can also be used to speed up Pollard rho when running many walks in parallel. We generalize these ideas and exploit the fact that for any two elliptic curve points X and Y , we can effici...

Initialization of model parameters is crucial in the conventional 1D inversion of DC electrical data, since a poor guess may result in undesired parameter estimations. In the present work, we investigate the performance of neural networks in the direct inversion of DC sounding data, without the need of a priori information. We introduce a two-step network approach where the first network identi...

Background Myocardial T1 mapping remains a challenging task due to restrictions imposed by cardiac and respiratory motion. Modified Look-Locker Inversion Recovery (MOLLI) [1] is widely used for 2D cardiac T1-mapping. In MOLLI, the spin-lattice relaxation curve is sampled several times after a single magnetization preparation. The ECG triggered imaging induces a disturbance in the relaxation cur...

Elliptic Curve Public Key Cryptosystems are becoming increasingly popular for use in mobile devices and applications where bandwidth and chip area are limited. They provide much higher levels of security per key length than established public key systems such as RSA. The underlying operation of elliptic curve point multiplication requires modular multiplication, division/inversion and addition/...
