Atom-field dressed states in slow-light waveguide QED

2015

We discuss the properties of atom-photon bound states in waveguide QED systems consisting of single or multiple atoms coupled strongly to a finite-bandwidth photonic channel. Such bound states are formed by an atom and a localized photonic excitation and represent the continuum analog of the familiar dressed states in single-mode cavity QED. Here we present a detailed analysis of the linear and nonlinear spectral features associated with single- and multi-photon dressed states and show how the formation of bound states affects the waveguide-mediated dipole-dipole interactions between separated atoms. Our results provide a both qualitative and quantitative description of the essential strong…

The Sensory Neocortex and Associative Memory

2016

Most behaviors in mammals are directly or indirectly guided by prior experience and therefore depend on the ability of our brains to form memories. The ability to form an association between an initially possibly neutral sensory stimulus and its behavioral relevance is essential for our ability to navigate in a changing environment. The formation of a memory is a complex process involving many areas of the brain. In this chapter we review classic and recent work that has shed light on the specific contribution of sensory cortical areas to the formation of associative memories. We discuss synaptic and circuit mechanisms that mediate plastic adaptations of functional properties in individual …

Antibacterial properties and reduction of MRSA biofilm with a dressing combining polyabsorbent fibres and a silver matrix

2016

Objective: This study was designed to evaluate the antibacterial activity of a wound dressing which combines polyacrylate fibres and a silver lipido-colloid matrix (UrgoClean Ag, silver polyabsorbent dressing), against biofilm of methicillin-resistant Staphylococcus aureus (MRSA). Method: Samples of silver polyabsorbent dressing and the neutral form of this dressing (UrgoClean) were applied to biofilms of MRSA formed on a collagen I-coated surface, cultured for 24 hours. Different exposure times were tested (1, 2, 4 and 7 days) without dressing change. The biofilm reduction was quantified by using culture methods and by confocal laser scanning microscopy experiments. Results: The applicatio…

The growth of next-generation sequencing (NGS) datasets poses a challenge to the alignment of reads to reference genomes in terms of alignment quality and execution speed. Some available aligners have been shown to obtain high quality mappings at the expense of long execution times. Finding fast yet accurate software solutions is of high importance to research, since availability and size of NGS datasets continue to increase. In this work we present an efficient parallelization approach for NGS short-read alignment on multi-core clusters. Our approach takes advantage of a distributed shared memory programming model based on the new UPC++ language. Experimental results using the CUSHAW3 alig…

parSRA: A framework for the parallel execution of short read aligners on compute clusters

2018

The growth of next generation sequencing datasets poses as a challenge to the alignment of reads to reference genomes in terms of both accuracy and speed. In this work we present parSRA, a parallel framework to accelerate the execution of existing short read aligners on distributed-memory systems. parSRA can be used to parallelize a variety of short read alignment tools installed in the system without any modification to their source code. We show that our framework provides good scalability on a compute cluster for accelerating the popular BWA-MEM and Bowtie2 aligners. On average, it is able to accelerate sequence alignments on 16 64-core nodes (in total, 1024 cores) with speedup of 10.48 …

Electrospinning of Bioactive Wound-Healing Nets

2017

The availability of appropriate dressings for treatment of wounds, in particular chronic wounds, is a task that still awaits better solutions than provided by currently applied materials. The method of electrospinning enables the fabrication of novel materials for wound dressings due to the high surface area and porosity of the electrospun meshes and the possibility to include bioactive ingredients. Recent results show that the incorporation of biologically active inorganic polyphosphate microparticles and microspheres and synergistically acting retinoids into electrospun polymer fibers yields biocompatible and antibacterial mats for potential dressings with improved wound-healing propertie…

3D-Printed Products for Topical Skin Applications: From Personalized Dressings to Drug Delivery.

2021

3D printing has been widely used for the personalization of therapies and on-demand production of complex pharmaceutical forms. Recently, 3D printing has been explored as a tool for the development of topical dosage forms and wound dressings. Thus, this review aims to present advances related to the use of 3D printing for the development of pharmaceutical and biomedical products for topical skin applications, covering plain dressing and products for the delivery of active ingredients to the skin. Based on the data acquired, the important growth in the number of publications over the last years confirms its interest. The semisolid extrusion technique has been the most reported one, probably …

La tutela del menor víctima de la violencia de género : marco normativo procesal y penal

2021

The Spanish legal system provides specific protection for victims of gender violence, the paper addresses the legal situation of minors who are dependent on women victims of this type of violence. It analyses their procedural situation and, in particular, the criminal remedies for their protection. In a particular way, the aggravating circumstance of committing the act in their presence and the penalties that affect parental authority are examined.

La patria potestad prorrogada y la patria potestad rehabilitada en el nuevo proyecto de ley de reforma de la legislación civil y procesal para el apo…

2021

It is intended to analyze and reflect in the present work about the institution of the extension of parental authority and parental authority rehabilitated in the new regulation in the Draft Law that reforms the civil and procedural legislation to support people with disabilities in the exercise of their legal capacity. In this project, the extended parental authority and the rehabilitated parental authority are eliminated from the scope of disability, following a criterion that demands the treatment of people with disabilities with the attention that their specific situation requires, eliminating a regime that seems contrary to the system of promoting the autonomy of adults with disabiliti…

Derecho de acceso a la información : el desafío de una sociedad guiada por la transparencia en el ordenamiento jurídico español

2021

This study will address the two aspects of rights linked to information, the right to information and the right to information, to end with the formulation of some conclusions that, distancing themselves from a mere summary, seek to encourage doctrinal and political debate on assumptions that, being peacefully settled, should be reformulated in light of the repeated crisis of transparency. For this, it will be articulated by addressing, first, the most significant aspects of the right to information and its link with the right to freedom of expression, as well as the new challenges that these rights face in the digital age, to then analyze the right to information, its regulation in the Spa…
