The odderon singularity is studied in perturbative QCD in the framework of the Bartels-Kwieciński-Praszalowicz (BKP) equation. Arguments for the odderon intercept being exactly equal to unity are given. Besides, a variational method based on a complete system of one-gluon functions is presented. For the odderon, the highest intercept calculated by this method is 1 − (Ncαs/π) 0.45. Comparison to...

| We consider a number of problems concerning the overlaps or coincidences of two periodic pulse trains. We show that the rst intercept time of two pulse trains started in phase is a homogeneous Diophantine approximation problem which can be solved using the convergents of the simple continued fraction (s.c.f.) expansion of the ratio of their pulse repetition intervals (PRIs). We nd that the in...

Studies of participation levels and destinations for economic activities such as recreation have traditionally been analyzed using random samples of households, with either cross-section observations or panel data on repeat choices obtained from diaries. In travel demand analysis, an alternative sampling design is to conduct intercept surveys at sites. This can result in substantial reductions ...

A 45MHz-2.5GHz broadband CMOS up-conversion mixer implemented in a conventional 0.18µm technology is presented this letter. The offered employs bisymmetric class-AB input stage order to provide high linearity and match the IF impedance over 0.3-20.15MHz frequency range. draws 3mA current from 1.8V supply voltage, core chip dimension of 0.05*0.08mm2. At range 45MHz-2.5GHz, output third-order int...

Near-infrared spectroscopy (NIRS) is a noninvasive optical technique to monitor cerebral oxygen saturation at the bedside. Despite its applicability, NIRS has had limited clinical use because of concerns about accuracy, noted by intersubject variability in slope and intercept of the line between NIRS- and weighted-average arterial-cerebrovenous saturation (SMO2). This study evaluated transcrani...

High-performance multistage data converters and sub-sampling frequency downconverters typically require track and hold amplifiers (THAs) with high sampling rates and high linearity. This paper presents a THA for sub-sampling communications applications based on a diode bridge design with high-speed Schottky diodes and an improved current source approach for enhanced linearity. Implemented in a ...

Large sample properties are studied for a …rst-order autoregression (AR(1)) with a root greater than unity. It is shown that, contrary to the AR coe¢ cient, the leastsquares (LS) estimator of the intercept and its t-statistic are asymptotically normal without requiring the Gaussian error distribution, and hence an invariance principle applies. While the invariance principle does not apply to th...

Three indexes developed originally to assess left ventricular contractile performance were applied instead to the right ventricle (RV) in 11 conscious dogs: the relation between stroke work and end-diastolic volume (EDV), termed the preload recruitable stroke work (PRSW) relation; the end-systolic pressurevolume (ESPV) relation; and the maximum dP/dt (dP/dtm )-EDV relation. The reproducibility,...
