Predictive role of ankle MRI for tendon graft choice and surgical reconstruction.
2020
Purpose: Tendon transfers have become a common surgical procedure around the ankle. In this study, we sought to evaluate the existence of a correlation between specific anthropometric parameters and the size of some ankle tendons measured on MRI, in particular those mostly used as graft in ankle surgery. Methods: We recorded gender, height, weight, and body mass index (BMI) of 113 patients (57 females; mean age: 42 ± 18) who underwent ankle MRI. MRI measurements performed by a radiologist were: axial shortest diameter of Achilles (AT), posterior tibialis (PTT), flexor digitorum longus (FDLT), flexor hallucis longus (FHLT), peroneus longus (PLT), and anterior tibialis (ATT) tendons, intermal…
Techniques de construction traditionnelles et techniques romaines dans le théâtre d’Althiburos et les monuments de spectacle de l’Afrique Proconsulai…
2023
The contribution aims to study the relationship between the traditional construction techniques of the territories of Proconsular Africa and those imported by the Romans and used in the construction of entertainment buildings, in particular theaters and amphitheatres, also taking into account the importation of typological models, starting from the “case study” of the theater of Althiburos. During the 1st and 2nd centuries AD there is a gradual introduction of Roman construction techniques, such as the opus caemaenticium, especially in the construction of substructures and vaults, sometimes with the importation of urban models, of techniques but also of Italic workers (just think of the opu…
Statistical analysis of engraving traces on a 3D digital model of prehistoric stone stelae
2016
International audience; Studying cultural heritage artefacts, using 3D digital models, is gaining interest. It not only allows applications in documentation and visualisation, but also permits further contact-less examination. In this paper, we are presenting a statistical analysis of stone engravings based on features that were semi-automatically extracted from 3D acquisition data. Our objects of study are two Neolithic stone stelae and a faithful replica that was created in the course of an archaeological study. We use common statistical methods and investigate the populations of depth and diameter of the engraving traces, as well as their correlation. We observe that the erosion of the t…
Marks and Epigraphs on Iberian Amphorae. II
2015
Se presenta la segunda parte del repertorio de marcas y epígrafes sobre ánforas ibéricas, con la intención de completar un fenómeno heredero del mundo púnico. Se pretende ir acotando el/los posible/s significado/s de tales marcas, su distribución territorial y su marco cronológico. Las marcas incisas son, en esta ocasión, más numerosas que las impresas y se ha detectado una nueva técnica postcocción (con pintura y carbón) restringida al noreste peninsular. This paper is the second part of the repertoire of marks and epigraphs on Iberian amphorae. The goal is to complete this work, which is related to the Punic world, and know the possible meanings of such marks, their geographical distribut…
A Neural Solution for a Mobile Robot Navigation into Unknown Indoor Environments Using Visual Landmarks
1998
In this paper we present a neural solution for a mobile robot navigation into unknown indoor environments by using landmarks. Robot navigation task is implemented by two groups of processes based on MLP neural networks classifiers: a Low Level Vision System performs obstacle avoidance and corridor following, while an High Level Vision System extracts landmarks contents and performs goal directed navigation. A path-planner manages the two navigation systems and interacts with the robot hardware. The proposed solution is very strong and flexible and can be used to drive a mobile robot in real indoor environments. In the paper experimental results are also reported.
Insight into the noble crayfish morphological diversity: a geometric morphometric approach.
2022
The noble crayfish (Astacus astacus), a keystone species of high ecological, economic, and cultural importance in Europe, is threatened due to a long-term population decline caused by anthropogenic pressure on its habitats, the presence of non-indigenous invasive crayfish species and climate change. Since the effective protection of the remaining populations requires conservation measures based on the comprehensive knowledge of the species, including good understanding of its genetic and morphological variability, our aim was to study morphological features of the noble crayfish in Croatia using geometric morphometrics for the first time. We applied two-dimensional geometric morphometrics t…
Valodas izvēle tirdzniecības zīmēs
2017
Valoda ir nozīmīga ikdienas komunikācijas daļa. Uzņēmēji to izmanto, lai paustu savus biznesa mērķus un idejas. Viens no svarīgākajiem kompānijas aspektiem ir tās zīmola attēls; tā ir pirmā lieta, kas reprezentē kompāniju un ļauj tai tikt uztvertai kā labam pakalpojuma sniedzējam potenciālo klientu acīs. Lai zīmols būtu juridiski aizsargāts, tam ir jābūt reģistrētam kā tirdzniecības zīmei. Pētījuma mērķis ir noskaidrot, kādus lingivistiskos un paralingvistiskos līdzekļus pakalpojumu sniedzēji Baltijas valstīs izmanto tirdzniecības zīmēs. Lai veiksmīgi veiktu pētījumu, tika analizētas 45 tirdzniecības zīmes, kuras ir reģistrētas Baltijas valstu Patentu iestādēs. Gandrīz visas analizētās tird…
p53 as the main traffic controller of the cell signaling network
2010
Among different pathological conditions that affect human beings, cancer has received a great deal of attention primarily because it leads to significant morbidity and mortality. This is essentially due to increasing world-wide incidence of this disease and the inability to discover the cause and molecular mechanisms by which normal human cells acquire the characteristics that define cancer cells. Since the discovery of p53 over a quarter of a century ago, it is now recognized that virtually all cell fate pathways of live cells and the decision to die are under the control of p53. Such extensive involvement indicates that p53 protein is acting as a major traffic controller in the cell signa…
Exudates as Landmarks Identified through FCM Clustering in Retinal Images
2020
The aim of this work was to develop a method for the automatic identification of exudates, using an unsupervised clustering approach. The ability to classify each pixel as belonging to an eventual exudate, as a warning of disease, allows for the tracking of a patient&rsquo
Supporting tourism with public interactive displays
2019
Interactive displays are common in public and semi-public areas, such as museums, shopping malls, train stations, and even on streets. Especially with the emergence of new ways of interaction, interactive displays could be introduced to popular tourist attractions to support tourism. The aim of this tutorial is to prepare its participants for designing such interactive public displays. The tutorial will first introduce participants to state of the art in interactive public displays. This will be followed by a city tour where a number of local attractions are visited. Finally, the participants will brainstorm and create concepts for novel interactive public displays that aim to improve the e…
