Attachment of two nitrilotriacetic acid-based ligands to a protein α-helix in an i, i + 4 configuration produces an octadentate chelating motif that is able to bind paramagnetic lanthanide ions rigidly and with high affinity, leading to large pseudocontact shifts and residual dipolar couplings in the NMR spectrum.

Repair of tetralogy of Fallot (TOF) has shown excellent outcomes. However it leaves varying degrees of residual hemodynamic impairment, with severe pulmonary stenosis (PS) and free pulmonary regurgitation (PR) at both ends of the spectrum. Since the 1980s, studies evaluating late outcomes after TOF repair revealed the adverse impacts of residual chronic PR on RV volume and function; thus, a tur...

We study fractional Brownian motions in multifractal time, a model for multifractal processes proposed recently in the context of economics. Our interest focuses on the statistical properties of the wavelet decomposition of these processes, such as residual correlations (LRD) and stationarity, which are instrumental towards computing the statistics of wavelet-based estimators of the multifracta...

We analyze a SU(N) gauge theory on M4 × T . We find and catalogue all possible degenerate zero-energy stable configurations in the case of trivial or non-trivial ’t Hooft non abelian flux. We describe the residual symmetries of each vacua and the 4-dimensional effective spectrum in terms of continous and discrete parameters, respectively.

In this paper, we discuss the split band code-excited linear prediction (SB-CELP) speech coder which employs an iterative version of the harmonic sinusoidal coding algorithm to encode the periodic contents of speech signal. Speech spectrum is split into two frequency regions of harmonic and random components and a reliable fundamental frequency is estimated for the harmonic region using both sp...

determination of drug residues in food is of great importance due to their toxicity. long-term exposure with low level of drug residues could be important, especially in children. based on document study, oxytetracycline (otc) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...

This paper presents a general theory for developing new Svoboda-Tung (or simply NST) division algorithms not suuering the drawbacks of the \classical" Svoboda-Tung (or simply ST) method. NST avoids the drawbacks of ST, by means of a proper recoding of the two most signiicant digits of the residual before selecting the most signiicant digit of this recoded residual as the quotient-digit. NST rel...

CONCLUSIONS Psychoacoustic functions relating the depth and duration of tinnitus suppression ('residual inhibition') to the center frequency of band-passed noise masking sounds appear to span the region of hearing loss, as do psychoacoustic measurements of the tinnitus spectrum. The results (1) suggest that cortical map reorganization induced by hearing loss is not the principal source of the t...

Aims. We develop and validate tools for estimating residual noise covariance in Planck frequency maps, we also quantify signal error effects and compare different techniques to produce low-resolution maps. Methods. We derived analytical estimates of covariance of the residual noise contained in low-resolution maps produced using a number of mapmaking approaches. We tested these analytical predi...

Residual dipolar couplings measured for weakly aligned proteins provide important restraints for molecular structure determinations by NMR1 spectroscopy which cannot be obtained otherwise.2 Residual dipolar couplings are usually measured by comparing multiplet splittings measured in anisotropic phase with those measured in isotropic phase.2,3 In the absence of scalar couplings, a residual dipol...
