Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Adaptive Hamiltonian-Based Energy Control with Built-In Integrator for PEMFC Hybrid Power Conversion Architecture

open access: yesEnergies, 2023
In this article, an Adaptive Hamiltonian-Based Energy Control (AHBEC) with a built-in integrator is introduced for the Proton-Exchange Membrane Fuel Cell (PEMFC) hybrid power-conversion system. The presented additional built-in integrator is based on the

Passives and impersonals [PDF]

open access: yesJournal of Linguistics, 2003
This paper argues that the term ‘passive’ has been systematically misapplied to a class of impersonal constructions that suppress the realization of a syntactic subject. The reclassification of these constructions highlights a typological contrast between two types of verbal diathesis and clarifies the status of putative ‘passives of unaccusatives’ and

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Human Modeling and Passivity Analysis for Semi-Autonomous Multi-Robot Navigation in Three Dimensions

open access: yesIEEE Open Journal of Control Systems
In this article, we study a one-human-multiple-robot interaction for human-enabled multi-robot navigation in three dimensions. We employ two fully distributed control architectures designed based on human passivity and human passivity shortage. The first

An Assertive Method as Help in Catechesis?

open access: yesThe Person and the Challenges, 2017
The problem of discipline, and motivation in the learning process, is ever more glaring in catechesis. The assertive approach attempts to, at least partially, solve this problem in modern education.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Robustification of Continuous-Time ADMM against Communication Delays under Non-Strict Convexity: A Passivity-Based Approach

open access: yesSICE Journal of Control, Measurement, and System Integration, 2020
In this paper, we address a class of distributed optimization problems with non-strictly convex cost functions in the presence of communication delays between an agent and a coordinator.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

La experiencia mística de Dios en las Confesiones de San Agustín en relación con Las Moradas de Santa Teresa [PDF]

open access: yesIndivisa, Boletín de Estudios e Investigación, 2012
Saint Teresa has the experience of God in The Mansions, mainly as Husband. She is led to him through courtship and wedding in order to reach its climax in spiritual marriage. Love is the key. Nobody questions, at least in religious contexts, its mystical
