Abstract:
The article clarifies the distinction between “contradiction” and “conflict” notions (proposed in its first part) based on conflictological works of P.G. Kuznetsov, L. Kriesberg, J.W. Burton et al. It reviews the options of monitoring the achievement of interdisciplinary business game (IBG) remote sub-goal — formation of a new way of thinking among its participants. In addition, the article proposes IBG invariant in LT-dimension — as a basis for constructing a system of parameters for evaluation of the IBG process and results, as well as a foundation for the

Abstract:
In this paper, we present a general methodology suitable for analyzing any IBG (Integrated Bragg Grating) as a linear time-invariant (LTI) system using the effective refractive index (ERI) and transfer matrix method (TMM). This approach is based on the translation of the IBG’s physical structure into a matrix of effective refractive indexes, neff, which is wavelength-dependent and describes the behavior of light in the IBG while avoiding the use of approximations like Coupled Mode Theory does. This procedure allows to obtain very accurate reflection and transmission spectra, regardless of the

Abstract:
Interior-boundary conditions (IBCs) have been suggested as a possibility to circumvent the problem of ultraviolet divergences in quantum field theories. In the IBC approach, particle creation and annihilation is described with the help of linear conditions that relate the wave functions of two sectors of Fock space: [Formula: see text] at an interior point [Formula: see text] and [Formula: see text] at a boundary point [Formula: see text], typically a collision configuration. Here, we extend IBCs to the relativistic case. To do this, we make use of Dirac’s concept of multi-time wave functions,

AbstractThe two alleles an individual carries at a locus are identical by descent (ibd) if they have descended from a single ancestral allele in a reference population, and the probability of such identity is the inbreeding coefficient of the individual. Inbreeding coefficients can be predicted from pedigrees with founders constituting the reference population, but estimation from genetic data is not possible without data from the reference population. Most inbreeding estimators that make explicit use of sample allele frequencies as estimates of allele probabilities in the reference population

Abstract Background The gut microbiota is a key element to support host homeostasis and the development of the immune system. The relationship between the microbiota and immunity is a 2-way road, in which the microbiota contributes to the development/function of immune cells and immunity can affect the composition of microbes. In this context, natural killer T cells (NKT cells) are distinct T lymphocytes that play a role in gut immunity and are influenced by gut microbes. In our work, we investigated the involvement of invariant NKT cells (iNKT) in intestinal homeostasis. Results We found that

Abstract Background All-trans retinoic acid (RA) plays a crucial role in promoting Foxp3+ Treg generation while reciprocally inhibiting Th1/Th17 generation. Our previous research highlighted that in the face of inflammatory conditions, RA plays a contrary role where it aggravates intestinal inflammation by promoting interferon (IFN) γ and interleukin (IL)-17 differentiation in vitro. Methods In this study we translated our in vitro results into a clinical setting where we estimated mucosal and serum RA levels along with the immunophenotypic profile (IL-17, IFNγ, Foxp3, IL-10) in adaptive (CD4,

Abstract:
Inflammatory bowel disease (IBD) pathogenesis has been linked to the aberrant activation of the Gut-associated lymphoid tissues against components of the intestinal microbiota. Although the contribution of CD4+ T helper cells to inflammatory processes is being increasingly acknowledged, the functional engagement of human invariant natural killer T (iNKT) cells is still poorly defined. Here, we evaluated the functional characteristics of intestinal iNKT cells during IBD pathogenesis and to exploit the role of mucosa-associated microbiota recognition in triggering iNKT cells’ pro-inflammatory re

Abstract Background Inflammatory bowel disease (IBD) manifests as chronic inflammation of the gastrointestinal tract and is characterized by a deregulated immune response targeting the gut microflora. Mucosal-associated invariant T (MAIT) cells have been identified as a possible key player in IBD. Activated MAIT cells produce cytokines including IL-26, a newly discovered cytokine involved in the pathology of IBD. Interestingly, IL-26 is not expressed in mice and therefore its effect on the course of inflammation has not been yet fully investigated. Similarly, studies employing human cell cultu

Abstract Background It is known that the mucosal-associated invariant T (MAIT) cells are the innate-like T cells that are restricted by the major histocompatibility complex-related molecule 1 (MR1), and that these cells express a semi-invariant T cell receptor. We have previously reported that the activation status of the circulating MAIT cells in patients with Ulcerative Colitis (UC) is associated with disease activity, and these cells infiltrate the inflamed colonic mucosa. These findings imply that MAIT cells are involved in the pathogenesis of Inflammatory Bowel Disease (IBD). However, the

Abstract:
In automatic speech recognition systems (ASRs), training is a critical phase to the system?s success. Communication media, either analog (such as analog landline phones) or digital (VoIP) distort the speaker?s speech signal often in very complex ways: linear distortion occurs in all channels, either in the magnitude or phase spectrum. Non-linear but time-invariant distortion will always appear in all real systems. In digital systems we also have network effects which will produce packet losses and delays and repeated packets. Finally, one cannot really assert what path a signal will take, and

Advantages of using the KLD are that it: (1) possesses a natural hi-erarchical property such that IBE implies PBE and PBE implies ABE, (2) satisfies the properties of a true distance metric, (3) is invariant to monotonic transformations of the data, (4) generalizes easily to the mul-tivariate case where equivalence on more than one parameter (e.g., AUC, Cmax and Tmax) is required and (5) is applicable over a wide range of distributions of the response variable (e.g., those in the exponential fam-ily). Patterson et al. (2001) and Dragalin et al. (2002), described the results of a simulation study and a retrospective analysis of 22 replicate design datasets, to compare testing for IBE using the KLD with testing based on the FDA-recommended metric defined earlier in Section 7.4. One notable finding of these studies was that the KLD metric identified more datasets as being of concern than the FDA-recommended metric. This appeared to be due to ability of the FDA-recommended metric to reward novel formulations for which the within-subject variance is decreased relative to the reference. 7.8 Modelling pharmacokinetic data Although AUC and Cmax are adequate for testing for bioequivalence, there is sometimes a need to model the drug concentrations over time. Fitting such models aids the understanding of how the drug is absorbed and eliminated from the body, as well as allowing model-based estimates of AUC and Cmax to be obtained. A popular type of model that is fitted in these circumstances is the compartmental model, which considers the body as made up of a number of compartments through which the drug circulates. For example, the circulating blood might be considered as the single compartment in a one-compartment model. If a drug is taken orally as a tablet, say, the drug is absorbed into this compartment as the tablet dissolves in the stomach and is eliminated from this compartment by (among other things) the actions of the liver and kidneys. While the tablet is still being dissolved in the stomach, the rate of absorption of the drug into the circulating blood is greater than the rate that is eliminated."

Abstract:
The usual view of a soliton in an optical fiber is that it obeys the classical Maxwell equations, and propagates unchanged down a lossless fiber. Of course, it is well known that an optical amplifier introduces noise in position. It is less well known that even a perfectly lossless fiber, without an amplifier, is unable to support the classical invariant solution. Instead, all solitons experience quantum noise in position and phase, and this noise increases with propagation distance. Experimenters at IBM laboratories have recently observed the first quantum effects in solitons. These experimen
