Generalization of the Receiver-Operating Characteristic Curve to Determine the Normal Hemoglobin Range Cutoff Points in Pregnant Women
ROC curve Sensitivity and Specificity Biomarkers Pregnancy Outcomes
2015/10/13
Background: Identification of a normal range for biomarkers, based on pregnancy outcomes (caused by their high or low values) is of special importance in clinical studies. As some pregnancy outcomes c...
Expression, Purification, and Characteristic of Tibetan Sheep Breast Lysozyme Using Pichia pastoris Expression System
Pichia pastoris Purification Secretory Expression Tibetan Sheep
2016/5/16
A lysozyme gene from breast of Tibetan sheep was successfully expressed by secretion using a-factor signal sequence in the methylotrophic yeast, Pichia pastoris GS115. An expression yield and specific...

2014/3/28
The variability of characteristic components of aronia (Aronia melanocarpa, black chokeberry) and to evaluate the chemical composition and quality of aronia products in order to complete the already a...
A quasi-polynomial algorithm for discrete logarithm in finite fields of small characteristic
cryptanalysis number theory
2014/3/12
In the present work, we present a new discrete logarithm algorithm, in the same vein as in recent works by Joux, using an asymptotically more efficient descent approach. The main result gives a quasi-...
A new index calculus algorithm with complexity $L(1/4+o(1))$ in very small characteristic
Number Theory Discrete Logarithms
2013/4/18
In this paper, we describe a new algorithm for discrete logarithms in small characteristic. It works especially well when the characteristic is fixed. Indeed, in this case, we obtain a total complexit...
Black Spot Determination of Traffic Accident Locations and Its Spatial Association Characteristic Analysis Based on GIS
Black Spot Traffic Accident Spatial Analysis
2013/3/5
In general, the location of traffic accidents is described as an address with text, so they are difficult to display on the map. The paper discusses how to utilize the geocoding technology and VRS-GPS...
Characteristic Set Algorithms for Equation Solving in Finite Fields and Applications in Cryptanalysis
Characteristic set finite field proper triangular set regular triangular set Boolean function stream cipher
2013/9/9
Efficient characteristic set methods for computing solutions of polynomial equation systems in a finite field are proposed. The concept of proper triangular sets is introduced and an explicit formula ...

Existence of covers fixed ramification positive characteristic Algebraic Geometry
2012/6/25
We discuss two elementary constructions for covers with fixed ramification in positive characteristic. As an application, we compute the number of certain classes of covers between projective lines br...

2012/6/25
The goal of this paper is to derive a formula for the finite dimensional joint characteristic function (the Fourier transform of the finite dimensional distribution) of the coupled process ${(W_{t},L_...
The first $L^2$-Betti number and approximation in arbitrary characteristic
First L2-Betti number approximation in prime characteristic Group Theory
2012/6/19
Let G be a finitely generated group and (G_i) a descending chain of finite index normal subgroups of G. Given a field K, we consider the sequence b_1(G_i;K)/[G:G_i] of normalized first Betti numbers o...

2012/6/15
In 2010, M. Studen\'y, R. Hemmecke, and Linder explored a new algebraic description of graphical models, characteristic imsets. Compare with standard imsets, characteristic imsets have several advanta...
Characteristic spectral features of the polarized fluorescence of human breast cancer in the wavelet domain
Florescence Spectroscopy Wavelet Transform Biomedical Optics Breast Cancer
2012/5/17
Wavelet transform of polarized fluorescence spectra of human breast tissues is found to localize spectral features that can reliably differentiate normal and malignant tissue types. The intensity diff...
