Abstract:

The characteristic features of the supporting structure are its topology, geometry and parameters of the elements. The process of creating a structure goes from the project to its material embodiment. The topology defines the contour of the load resistance, which finally manifests itself in the configuration and material. The fundamental beginning of the design project is the variational principle of structural synthesis with energy content. It provides a minimum consumption of material. Its fundamental distribution is made at the stage of topology design as a confrontation with an external fo

Abstract:

In Vladimir Propp's Morphology of the Folktale, uncertainty has continually hovered over the pivotal role occupied by the eighth function in what the Russian theorist suggested was a single invariant wondertale structure. In this article, I suggest that this discrepancy can be resolved: there are in fact two major types of wondertale, with their separate structures pivoting on the choice of one or other of the two eighth function options.

A string-net model associates a vector space to a surface in terms of graphs decorated by objects and morphisms of a pivotal fusion category modulo local relations. String-net models are usually considered for spherical fusion categories, and in this case, the vector spaces agree with the state spaces of the corresponding Turaev–Viro topological quantum field theory. In the present work, some effects of dropping the sphericality condition are investigated. In one example of nonspherical pivotal fusion categories, the string-net space counts the number of [Formula: see text]-spin structures on

Abstract:

SLC6A14 (ATB0,+) is a sodium- and chloride-dependent neutral and dibasic amino acid transporter that regulates the distribution of amino acids across cell membranes. The transporter is overexpressed in many human cancers characterized by an increased demand for amino acids; as such, it was recently acknowledged as a novel target for cancer therapy. The knowledge on the molecular mechanism of SLC6A14 transport is still limited, but some elegant studies on related transporters report the involvement of the 12 transmembrane α-helices in the transport mechanism, and describe structural rearrangeme

Abstract:

In Saccharomyces cerevisiae, heterochromatin structures required for transcriptional silencing of the HML and HMR loci are duplicated in coordination with passing DNA replication forks. Despite major reorganization of chromatin structure, the heterochromatic, transcriptionally silent states of HML and HMR are successfully maintained throughout S-phase. Mutations of specific components of the replisome diminish the capacity to maintain silencing of HML and HMR through replication. Similarly, mutations in histone chaperones involved in replication-coupled nucleosome assembly reduce gene silencin

Background: Prior to 2012, the mesentery was perceived as a fragmented structure, lacking distinct functional and anatomical characteristics, and was merely considered part of other digestive organs.

The continuous structure and unique tissue properties of the mesentery classify it as the 78th independent organ in the human body. Insights into mesenteric adipose tissue have enhanced our

Three-dimensional protein structure prediction from amino acid sequence has been a thought-provoking task for decades, but it of pivotal importance as it provides a better understanding of its function.

Still there is no single method which can predict all the protein structures. In this review, we describe the four stages of protein structure determin

Abstract:

Since the appearance of “pivotal construction”, scholars have always questioned its existence and wanted to classify it into the category of other syntactic constructions. Therefore, it is necessary to make a more detailed distinction between the pivotal construction and the other similar syntactic constructions. Generally, the pivotal construction can be abbreviated as N1 + V1 + N2 + V2, which is the same as in other syntactic constructions or sentence patterns: subject-predicate structure as the object construction, serial predicate construction, fused serial predicate and pivotal constructi

Abstract:

Reinforced concrete structures are exposed to a progression of activities all through their life expectancy which may be the purpose behind damage. Subsequently, rehabilitation of existing structures is typically performed either to restore structural limit because of decay or damage or to broaden existing structural limit due to expanded loads. To fortify existing structures, numerous new creative materials like progressed fiber-reinforced polymers (FRPs) are discovered to be acceptable substitute for reinforcing materials like steel. They are actualized to fortify the presentation of structu

Abstract:

Abstract Motivation Polyproline II (PPII) is a common conformation, comparable to α-helix and β-sheet. PPII, recently termed with a more generic name—κ-helix, adopts a left-handed structure with 3-fold rotational symmetry. Lately, a new type of binding mechanism—the helical lock and key model was introduced in SH3-domain complexes, where the interaction is characterized by a sliding helical pattern. However, whether this binding mechanism is unique only to SH3 domains is unreported. Results Here, we show that the helical binding pattern is a universal feature of the κ-helix conformation, prese

Abstract:

Crystallographic structural analysis is an essential method for the determination of protein structure. However, crystallization of a protein of interest is the most difficult process in the analysis. The process is often hampered during the sample preparation, including expression and purification. Even after a sample has been purified, not all candidate proteins crystallize. In this mini-review, the current methodologies used to overcome obstacles encountered during protein crystallization are sorted. Specifically, the strategy for an effective crystallization is compared with a pipeline whe

Full text

Abstract:

Reliability assessments are pivotal in evaluating system quality and have found extensive application in manufacturing. This research delves into a system comprising five components, one of which is a bridge network. The components are presumed to follow a Bilal lifetime distribution with a failure rate that changes over time. Four distinct methods are employed to enhance the components within the system. This study involves the computation of δ-fractiles and reliability equivalence factors (REFs). Additionally, a numerical case study is provided to elucidate the theoretical findings.

Full text

Abstract:

PIWI-interacting RNAs (piRNAs), a class of small non-coding RNAs (sncRNAs) with 24–32 nucleotides (nt), were initially identified in the reproductive system. Unlike microRNAs (miRNAs) or small interfering RNAs (siRNAs), piRNAs normally guide P-element-induced wimpy testis protein (PIWI) families to slice extensively complementary transposon transcripts without the seed pairing. Numerous studies have shown that piRNAs are abundantly expressed in the brain, and many of them are aberrantly regulated in central neural system (CNS) disorders. However, the role of piRNAs in the related developmental

Abstract:

Protein structure prediction is pivotal for understanding the structure-function relationship of proteins, advancing biological research, and facilitating pharmaceutical development and experimental design. While deep learning methods and the expanded availability of experimental 3D protein structures have accelerated structure prediction, the dynamic nature of protein structures has received limited attention. This study introduces an innovative 4D diffusion model incorporating molecular dynamics (MD) simulation data to learn dynamic protein structures. Our approach is distinguished by the fo
