Abstract:

ABSTRACT Relational structures of organisms and the human mind are naturally represented in terms of novel variable topology concepts, non-Abelian categories and Higher Dimensional Algebra– relatively new concepts that would be defined in this tutorial paper. A unifying theme of local-to-global approaches to organismic development, evolution and human consciousness leads to novel patterns of relations that emerge in super- and ultra- complex systems in terms of compositions of local procedures [1]. The claim is defended in this paper that human consciousness is unique and should be viewed as a

Abstract:

Modular structures are crystal structures built by subperiodic (zero-, mono- or diperiodic) substructures, called modules. The whole set of partial operations relating substructures in a modular structure build up a groupoid; modular structures composed of identical substructures are described by connected groupoids, or groupoids in the sense of Brandt. A general approach is presented to describe modular structures by Brandt's groupoids and how to obtain the corresponding space groups, in which only the partial operations that have an extension to the whole crystal space appear.

Abstract:

Corneal grafts interact with their hosts via complex immunobiological processes that sometimes lead to graft failure. Prediction of graft failure is often a tedious task due to the genetic and nongenetic heterogeneity of patients. As in other areas of medicine, a reliable prediction method would impact therapeutic decision-making in corneal transplantation. Valuable insights into the clinically observed heterogeneity of host responses to corneal grafts have emerged from multidisciplinary approaches, including genomics analyses, mechanical studies, immunobiology, and theoretical modeling. Here,

Abstract:

Introduction Papillae are small conical bumps found on the skin or mucous membranes surfaces. In the mouth, the parotid papillae are responsible for expelling saliva from the parotid gland to its cavity. Sialadenitis is an inflammation that affects the salivary gland and/or its duct. Objectives To report a variable parotid papilla case and its implication in sialadenitis. Materials and Methods The research was performed at the Morphofunctional Sciences Laboratory of the Faculdades Integradas de Patos - FIP. We used a cadaveric hemiface from the anatomy laboratory and a digital caliper rule for

Abstract:

In apparent contradiction to the theoretically predicted effect of population size on the quality/quantity of material culture, statistical analyses on ethnographic hunter–gatherers have shown an absence of correlation between population size and toolkit size. This has sparked a heated, if sometimes tangential, debate as to the usefulness of the theoretical models and as to what modes of cultural transmission humans are capable of and hunter–gatherers rely on. I review the directly relevant theoretical literature and argue that much of the confusion is caused by a mismatch between the theoreti

Abstract:

A linear-algebraic algorithm for identifying rigid-unit modes in networks of interconnected rigid units has recently been demonstrated. This article presents a series of enhancements to the original algorithm, which greatly improve its conceptual simplicity, numerical robustness, computational efficiency and interpretability. The improvements include the efficient isolation of constraints, the observation of variable-block separability, the use of singular value decomposition and a quantitative measure of solution inexactness.

Abstract:

Several protein families of different nature were studied for genetic relationship, correct alignment at non-homologous fragments, optimal sequence consensus construction, and confirmation of their actual relevance. A comparison of the genetic semihomology approach with statistical approaches indicates a high accuracy and cognition significance of the former. This is particularly pronounced in the study of related proteins that show a low degree of homology. The sequence multiple alignments were verified and corrected with respect to the questionable, non-homologous fragments. The verified ali

Abstract:

Recombination, the process by which DNA strands are broken and repaired, producing new combinations of alleles, occurs in nearly all multicellular organisms and has important implications for many evolutionary processes. The effects of recombination can be good , as it can facilitate adaptation, but also bad when it breaks apart beneficial combinations of alleles, and recombination is highly variable between taxa, species, individuals and across the genome. Understanding how and why recombination rate varies is a major challenge in biology. Most theoretical and empirical work has been devoted

Abstract:

Abstract We have seen in Chapter 8 that the process of maturation of the immune response i8 equivalent to evolution on a cellular scale. Once a B cell is triggered by encountering enough antigen, it enters a phase of rapid proliferation, during which the genes coding for the variable region on the antibodies produced by the B cell mutate at an enhanced rate, thus increasing the chances that an antibody with even higher affinity for the antigen will be produced. One theoretical framework which has proven useful in analysing evolving systems is that of the adaptive walk.
