Asymmetric Synthesis of Tetrasubstituted α-Aminophosphonic Acid Derivatives
(MDPI, 2021-05-27)Due to their structural similarity with natural α-amino acids, α-aminophosphonic acid derivatives are known biologically active molecules. In view of the relevance of tetrasubstituted carbons in nature and medicine and the ... -
Asymptotic Comparison of the Solutions of Linear Time-Delay Systems with Point and Distributed Lags with Those of Their Limiting Equations
(Hindawi Publishing Corporation, 2009)This paper investigates the relations between the particular eigensolutions of a limiting functional differential equation of any order, which is the nominal (unperturbed) linear autonomous differential equations, and the ... -
Asymptotic Hyperstability and Input–Output Energy Positivity of a Single-Input Single-Output System Which Incorporates a Memoryless Non-Linear Device in the Feed-Forward Loop
(MDPI, 2022)This paper visualizes the role of hyperstable controllers in the closed-loop asymptotic stability of a single-input single-output system subject to any nonlinear and eventually time-varying controller within the hyperstable ... -
Asymptotic Hyperstability of a Class of Linear Systems under Impulsive Controls Subject to an Integral Popovian Constraint
(Hindawi Publishing Corporation, 2013)This paper is focused on the study of the important property of the asymptotic hyperstability of a class of continuous-time dynamic systems. The presence of a parallel connection of a strictly stable subsystem to an ... -
At the beginnings of the funerary Megalithism in Iberia at Campo de Hockey necropolis
(Nature, 2022)[EN] The excavations undertaken at the Campo de Hockey site in 2008 led to the identification of a major Neolithic necropolis in the former Island of San Fernando (Bay of Cadiz). This work presents the results of the latest ... -

Atomic and Specificity Details of Mucin 1 O-Glycosylation Process by Multiple Polypeptide GalNAc-Transferase Isoforms Unveiled by NMR and Molecular Modeling
(American Chemical Society, 2022-02-24)[EN] The large family of polypeptide GalNAc-transferases (GalNAc-Ts) controls with precision how GalNAc O-glycans are added in the tandem repeat regions of mucins (e.g., MUC1). However, the structural features behind the ... -
Atomically-Precise Texturing of Hexagonal Boron Nitride Nanostripes
(Wiley, 2021-09)Monolayer hexagonal boron nitride (hBN) is attracting considerable attention because of its potential applications in areas such as nano- and opto-electronics, quantum optics and nanomagnetism. However, the implementation ... -
Atomistic Insights of Calmodulin Gating of Complete Ion Channels
(MDPI, 2020-02-14)Intracellular calcium is essential for many physiological processes, from neuronal signaling and exocytosis to muscle contraction and bone formation. Ca<sup>2+</sup> signaling from the extracellular medium depends both on ... -
Atomistic molecular simulations of Aβ-Zn conformational ensembles
(Wiley, 2024-01)The amyloid-forming Aβ peptide is able to interact with metal cations to form very stable complexes that influence fibril formation and contribute to the onset of Alzheimer's disease. Multiple structures of peptides derived ... -
Atomistic Simulations of Geopolymer Models: The Impact of Disorder on Structure and Mechanics
(ACS, 2018-06-13)Geopolymers are hydrated aluminosilicates with excellent binding properties. Geopolymers appeal to the construction sector as a more sustainable alternative to traditional cements, but their exploitation is limited by a ... -
