High Dynamic Range Spectral Imaging Pipeline For Multispectral Filter Array Cameras

2017

Spectral filter arrays imaging exhibits a strong similarity with color filter arrays. This permits us to embed this technology in practical vision systems with little adaptation of the existing solutions. In this communication, we define an imaging pipeline that permits high dynamic range (HDR)-spectral imaging, which is extended from color filter arrays. We propose an implementation of this pipeline on a prototype sensor and evaluate the quality of our implementation results on real data with objective metrics and visual examples. We demonstrate that we reduce noise, and, in particular we solve the problem of noise generated by the lack of energy balance. Data are provided to the community…

274 Comparative analysis of patients with acute coronary and cerebrovascular syndromes from the national French hospitalisation heath care system dat…

2011

Objective To compare vascular risk factor profiles and early outcomes in all French patients hospitalized for either acute coronary (ACS), or cerebrovascular syndromes (CVS), or both, between 2005 and 2008. Setting All French hospitals. Design Retrospective analysis. Data sources National database called “Hospital Discharge Diagnosis Records”. Main outcomes measured Number and annual rates, vascular risk factors, and early outcome of hospitalized patients for a unique stay for ACS or CVS or for both ACV and CVS in a 2-month time window. Results Over the 4-year study-period, 1,189,043 patients were hospitalized for CVS and/or ACS. Among these, 638,061 (53.7%) had CVS alone, 525,419 (44.3%) h…

Bibliometric analysis of core journals which publish articles of physical therapy on aging.

2020

Objective Increase in population's longevity has led to considerable efforts worldwide on physical therapy aging research. The aim of this study is to identify which are the main scientific journals, as well as the most productive authors, institutions and keywords related to the journals, that have published about physical therapy and aging. Methods Original articles published from 1990 to 2014 were retrieved from the bibliographic database Science Citation Index Expanded of Web of Science Core Collection. After standardization of the bibliographic information, a series of bibliometric indicators was obtained regarding authors, institutions, citation and keywords of the core journals using…

Magnification in apical surgerymusing the endoscope: a review

2011

Objective: A review is made to determine whether the use of the endoscope in endodontic surgery offers advantages in clinical practice, and whether it improves the clinical and radiographic outcomes of the procedure. Material and methods: The main search terms used were: endodontic surgery, apicoectomy, apical surgery, endoscope, and magnification devices . The authors searched the Medline database for articles published up to 1 September 2010. The review included experimental studies comparing endoscopic microstructural findings with the findings of the naked eye or other magnification devices, as well as prospective clinical trials comparing endodontic surgery with or without the use of a…

Simple bone cyst : description of 60 cases seen at a Brazilian School of Dentistry and review of international literature

2020

Background The aim of this study was to describe the relative frequency and the main demographic and clinic-radiographic features related to patients diagnosed with Simple bone cyst (SBC) in an Oral Diagnosis Service in Southeast Brazil and present a review and discussion of international literature on this topic. Material and Methods SBC cases from our service encompassing the period between 1978 and 2017 were selected. In addition, a literature search was performed in the Pubmed/MEDLINE online electronic database published between 1951 and 2019. Results A total of 2,459 cystic lesions were documented in our service, thus 60 patients were diagnosed with the SBC representing 2.4% of all jaw…

Multilevel Latent Profile Analysis With Covariates : Identifying Job Characteristics Profiles in Hierarchical Data as an Example

2018

Latent profile analysis (LPA) is a person-centered method commonly used in organizational research to identify homogeneous subpopulations of employees within a heterogeneous population. However, in the case of nested data structures, such as employees nested in work departments, multilevel techniques are needed. Multilevel LPA (MLPA) enables adequate modeling of subpopulations in hierarchical data sets. MLPA enables investigation of variability in the proportions of Level 1 profiles across Level 2 units, and of Level 2 latent classes based on the proportions of Level 1 latent profiles and Level 1 ratings, and the extent to which covariates drawn from the different hierarchical levels of th…

Design and implementation of the AMIGA embedded system for data acquisition

Acidity and basicity of primaryN-phenylnitramines: catalytic effect of protons on the nitramine rearrangement

2002

Para-substituted N-phenylnitramines were prepared either by oxidation of diazonium salts or by nitration under alkaline or acidic conditions. Isotopic [15N-NO2] labelling indicated that the bands characteristic of the N-nitro group appear in the 1318–1323 and 1585–1607 cm−1 regions. In the nitrogen NMR spectra, the nitramino group gives two resonances at −193 ± 3 (NH) and −32 ± 3 ppm (NO2). The chemical shifts in proton and carbon NMR spectra are predictable, based on increments and the additivity rule. The spectral data indicate the lack of conjugation between the nitramino group and another substituent bound to the ring. It seems to contradict the well-known fact that substituents strongl…

“NUMMI DIGITALI”: approcci innovativi per la conoscenza, gestione e valorizzazione del patrimonio numismatico del Museo Archeologico Regionale “A. Sa…

2022

The subject of the contribution is the “NUMMI DIGITALI” project which aims to enhance the numismatic collection of the Archaeological Museum “A. Salinas” in Palermo, closed to public use for over seventy years, which will become accessible thanks to the close interrelationship between numismatic-archaeological methodologies and the IT approach. The project, curated by Lavinia Sole, Numismatics researcher at the Culture and Society Department of the University of Palermo, within the PON "Research and Innovation" 2014-2020, Axis IV-Action IV.4, provides for the creation of a digital database, in line with the standards and cataloging tools of the ICCD and with the methodological guidelines of…
