Pre-distortion is basically a method by which one first stimulates a non-linear power amplifier (PA) with baseband samples and then observes the result of that stimulus at the PA output. Then , the amplitude-toamplitude modulation (AM/AM) and amplitude-to-phase modulation (AM/PM) effects of the PA are estimated. These estimated distortions are then removed from the PA by pre-distorting the inpu...

The expected number of real zeros of an algebraic polynomial ao a1x a2x · · · anx with random coefficient aj , j 0, 1, 2, . . . , n is known. The distribution of the coefficients is often assumed to be identical albeit allowed to have different classes of distributions. For the nonidentical case, there has been much interest where the variance of the jth coefficient is var aj ( n j ) . It is sh...

The goal of this paper is to provide new evidence on how the zero-interest rate policy implemented by the Bank of Japan has affected the sensitivity of money demand with respect to the opportunity cost of holding money. To the empirical ends of the analysis, the study makes use of the univariate conditional autoregressive value-at-risk (CAViaR) estimator to obtain robust quantile measures. The ...

It is shown that every set of n integers contains a subset of size Ω(n) in which no element is the average of two or more others. This improves a result of Abbott. It is also proved that for every > 0 and every m > m( ) the following holds. If A1, . . . , Am are m subsets of cardinality at least m each, then there are a1 ∈ A1, . . . , am ∈ Am so that the sum of every nonempty subset of the set ...

Amniotic membrane (AM), the most internal placental membrane, has unique properties including antiadhesive effects, bacteriostatic, wound protection and pain-reduction properties, as well as epithelialization initialization capacities. Furthermore, AM is widely available and less costly than other bioengineered skin substitutes. In a prospective pilot study, we evaluated the safety, feasibility...

Given α1, . . . , αm ∈ (0, 1), we characterize all integrable functions f : [0, 1] → C satisfying ∫ A1×···×Am f = 0 for any collection of disjoint measurable sets A1, . . . , Am ⊆ [0, 1] of respective measures α1, . . . , αm. We use this characterization to settle some of the conjectures in [S. Janson and V. Sós, More on quasi-random graphs, subgraph counts and graph limits, European J. Combin....

ABSTRACT- The aim of this study was to investigate the effects of “Arbuscular mycorrhizal fungi” (AM fungi) density and different growing media on the growth, photosynthesis parameters and yield of sweet pepper under greenhouse conditions. The experiment was conducted as a factorial plan based on control randomized design (CR...

The relationship between differential cell counts and latex-stimulated luminol and lucigenin-amplified chemiluminescence (CL) was investigated by mixing alveolar macrophages (AM) obtained at bronchoalveolar lavage (BAL) with allogeneic peripheral blood neutrophils (PMN) in varying proportions. In 5 non-asthmatic subjects, the mean luminol-amplified CL increased linearly from 2.1 (0.9 SEM) x 10(...
