Modal Analysis of a Reinforced Concrete Frame in Various States of Damage

2005

The purpose of this paper is to report selected results of an experiment in which two, natural size r/c frames were put on shaking table and subjected to a sequence of seismic excitations with increasing intensity interlaced with low level, diagnostic tests. The shaking table experiment aimed at working out new methodology for monitoring vibrations of r/c structures to assess their state. Characteristic decrease of natural frequencies and increase of structural damping was observed and analyzed in detail. It was interesting to note 20 per cent drop in natural frequencies prior to visual detection of any cracks.

Imaging to study solid tumour origin and progression: lessons from research and clinical oncology

2017

Biomedical imaging in recent decades has clarified our understanding of normal and pathological cellular processes in vivo. In particular, this approach recently provided insights into processes occurring at a molecular or genetic level rather than at the anatomical level. The evolution of this discipline by engineering have led to its integration into biomedical research to (1) increase sensitivity and resolution imaging and to (2) improve tissue and cell specificity. Currently, imaging approaches are used in three different biomedical areas: (a) identification of cellular processes in physiological and disease state; (b) in vivo single-cell imaging; and (c) identification of new prognosti…

Tumors of the central nervous system in children and adolescents.

2011

Multimodal treatment approaches for children with tumors of the central nervous system (CNS) have markedly contributed to improved survival. Before 1970, the survival rate among children with medulloblastoma, the most common malignant CNS tumor in children, was about 20%. At present, in contrast, cure can be achieved in more than 75% of children with a favorable constellation of risk factors. In this review article for clinicians, we give an overview of the current understanding of the pathology, presenting manifestations, early diagnosis, and treatment of CNS tumors in children and adolescents.We report the research findings of the German Treatment Network "HIT" and selectively review the …

Digestive Neuroendocrine Neoplasms (NEN): French Intergroup clinical practice guidelines for diagnosis, treatment and follow-up (SNFGE, GTE, RENATEN,…

2020

Abstract Introduction This document is a summary of the French Intergroup guidelines regarding the management of digestive neuroendocrine neoplasms (NEN) published in February 2020 ( www.tncd.org ). Methods All French medical societies involved in the management of NEN took part in this work. Recommendations were graded into four categories (A, B, C or D), according to the level of evidence found in the literature until May 2019. Results The management of NEN is challenging because of their heterogeneity and the increasing complexity of diagnostic and therapeutic procedures. Pathological analysis is required for their diagnostic and prognostic characterization, which mainly relies on differ…

Generative Adversarial Networks in Cardiology

2021

A B S T R A C T Generative Adversarial Networks (GANs) are state-of-the-art neural network models used to synthesize images and other data. GANs brought a considerable improvement to the quality of synthetic data, quickly becoming the standard for data generation tasks. In this work, we summarize the applications of GANs in the field of cardiology, including generation of realistic cardiac images, electrocardiography signals, and synthetic electronic health records. The utility of GAN-generated data is discussed with respect to research, clinical care, and academia. Moreover, we present illustrative examples of our GAN-generated cardiac magnetic resonance and echocardiography images, showin…

Advanced endoscopic imaging for gastric cancer assessment: new insights with new optics?

2014

The most immediate strategy for improving survival of gastric cancer patients is secondary prevention through diagnosis of early gastric cancer either through screening or follow-up of individuals at high risk. Endoscopy examination is therefore of paramount importance and two general steps are to be known in assessing gastric mucosa - detection and characterization. Over the past decade, the advent of advanced endoscopic imaging technology led to diverse descriptions of these modalities reporting them to be useful in this setting. In this review, we aim at summarizing the current evidence on the use of advance imaging in individuals at high-risk (i.e., advance stages of gastric atrophy/int…

Accommodation in human eye models: a comparison between the optical designs of Navarro, Arizona and Liou-Brennan.

2017

Aim To simulate and compare accommodation in accommodative and non-accommodative human eye models. Methods Ray tracing and optical design program was used. Three eye models were designed and studied: the Navarro, the Arizona and the Liou-Brennan. In order to make the Navarro and Liou-Brennan models to accommodate, specific geometric parameters of the models were altered with values that were chosen from the literature. For the Arizona model, its' mathematical functions for accommodation were used for the same accommodative demands. The simulation included four distances of accommodation for each model: at infinity, 3, 1 and 0.5 m.The results were diffraction images of a "letter F" for graph…

Analyzing American Public Diplomacy: The case of Brand USA. When Tourism becomes an Ideological Tool

2016

This paper aims to study the communicative strategies used in the American campaign of public diplomacy.Our objective in this work is twofold: first, to verify whether behind the action of rebranding the image of the U.S.A. there is an ideological agenda; second, to identify the communication dynamics - both textual and semiotic - which have contributed to make the campaign successful and whether they are in line with the communicative profile of the U.S.A., adopting a handful of current models in intercultural studies.

Modalità orientata sul partecipante in siciliano contemporaneo: i dati dell'Atlante linguistico della Sicilia (ALS)

2021

Il contributo descrive lo spazio semantico-funzionale codificato dalle costruzioni del siciliano contemporaneo che coinvolgono aviri a, putiri, sapiri e vuliri: (a) aviri a (avere da/dovere) + infinito; (b) putiri/sapiri (potere/sapere) + infinito; (c) vuliri (volere) + infinito; (d) vuliri + participio passato. In particolare, si farà riferimento a due domini funzionali intimamente connessi: la modalità orientata sul partecipante e la direttività. Il corpus di analisi è costituito dagli etnotesti e dalle produzioni a codice bloccato siciliano della sezione sociovariazionale dell’Atlante Linguistico della Sicilia (ALS), nonché dalle risposte ai quesiti traduttivi (italiano/siciliano, sicili…
