MLU and IPSyn measuring absolute complexity
2009
This article compares the results of Mean Length of Utterance (MLU) and Index of Productive Syntax (IPSyn) with the structural complexity of spontaneous utterances produced by 30-month-old Finnish children in a semi-structured playing situation. The comparison was carried out in order to determine the aspects of structural complexity which can be detected with MLU and IPSyn. This research adopts the frameworks of absolute complexity together with a multidimensional view of utterance structure and, furthermore, applies it through Utterance Analysis (UA). The results of the comparison between the metrics and changes in structural complexity discovered by UA reveal that MLU and IPSyn do functi…
Weld pool surface temperature measurement from polarization state of thermal emission
2014
This paper presents a passive polarimetry method using a division of aperture optical device in order to measure the temperature distribution at the weld pool surface. Thermal emission from a hot liquid metal was investigated at a near-infrared wavelength corresponding to a blind spectral window of a helium plasma generated during gas tungsten arc welding process. The refractive index of liquid metal and the surface radiance are deduced from the polarisation state of thermal emissions. Based upon the knowledge of both characteristics, the temperature distribution can be calculated. Conseil Régional de Bourgogne
Near IR stationary wave Fourier transform lambda meter in lithium niobate: multiplexing and improving optical sampling using spatially shifted nanogr…
2021
Several integrated optics solutions currently exist to develop monolithic, robust, and lightweight high-resolution spectrometers for spatial applications. An interesting option is generating a stationary wave inside a single-mode waveguide, and sampling the interference fringes using dielectric discontinuities on the surface of the waveguide. This allows the recording of the signal on a detector on top of the waveguide, and using dedicated Fourier transform methods to recover the spectrum of the source. All the difficulty is then linked to the length of the interferogram that is sampled. This determines the spectral resolution and the spacing between sampling centers, which are ultimately l…
IL-6 -174G/C polymorphism and IL-6 serum levels in patients with liver cirrhosis and hepatocellular carcinoma.
2011
Recently, a link between high levels of circulating IL-6 and hepatocellular carcinoma (HCC) has been proposed. In addition, single nucleotide polymorphisms (SNPs) in the promoter region of the IL-6 gene have been reported to be related to several inflammatory-related conditions, including cancer. The purpose of this article is: (1) to evaluate the frequencies of SNPs in the IL-6 promoter region at position -174 and IL-6 serum levels in a group of patients with HCC and underlying liver cirrhosis (LC), and compare them with a group of LC patients without HCC; (2) to determine whether a possible correlation exists between the allelic variations, IL-6 serum levels, and the risk of developing HC…
The abdominal wall incisional hernia repair in cirrhotic patients
2018
BACKGROUND: The incidence of abdominal wall hernia in cirrhotic patients with ascites is between 20 and 40%. Controversies regarding the treatment modality and surgical timing of abdominal wall incisional hernia repair in cirrhotic patients remain. The study proposed wants to analyze the abdominal incisional hernia repair in cirrhotic patients with ascites performed in a single center to determine post-operative morbidity, mortality and complication rate. PATIENTS AND METHODS: Cirrhotic patients with abdominal incisional hernia that underwent surgical operation for abdominal wall hernia repair at the "Policlinico Paolo Giaccone" at Palermo University Hospital between January 2015 and Decemb…
Octreotide compared with placebo in a treatment strategy for early rebleeding in cirrhosis. A double blind, randomized pragmatic trial.
1998
beta-Blockers and sclerotherapy prevent long-term upper digestive rebleeding in cirrhosis but they seem ineffective for early rebleeding. We compared octreotide with a placebo for the prevention of early rebleeding in cirrhotic patients. After control of acute upper digestive bleeding, 262 consecutive cirrhotic patients were randomized to octreotide 100 microgram subcutaneously three times a day for 15 days (n = 131) or to the placebo (n = 131), in a double blind pragmatic trial in which beta-blockers and/or sclerotherapy were allowed together with the experimental treatment. Separate randomization and analysis were performed according to whether patients were eligible for beta-blockers and…
Self Calibrating Nano-Ruler
2012
The aim of a nanoruler is to measure distances on a length scale in the order of nanometers. This concept can be realized by two plasmonic nanoparticles (usually spheres), which are placed within a short distance to each other. Since the plasmon modes of both particles are coupled, they influence each other along the interparticle axis (i.e. longitudinal plasmon mode, resulting in a shift of the resonance wavelength compared to the single particle. Because the resulting resonance wavelength depends on the interparticle distance, the spectral investigation of such a dimer allows the determination of the interparticle distance.
LED Based Dual Wavelength Heterochromatic Flicker Method for Separate Evaluation of Lutein and Zeaxanthin in Retina
2013
The decrease of density and consequentially optical density of macular pigment serves as a diagnostic mean for a number of ophthalmological pathologies, particularly as a risk factor for age related macular degeneration. Macular pigment absorbs light in short wavelength blue spectral range. Thus the optical density of macular pigment can be detected by various optical – both objective and subjective psychophysical techniques. Latter techniques use eye and brain visual pathways as spectral sensitive optical detector and decision maker, and exploit perception facility to process information flow in a unique manner to create various perception illusions. The psychophysical methods of detection…
NEXT-100 Technical Design Report (TDR). Executive summary
2012
[EN] In this Technical Design Report (TDR) we describe the NEXT-100 detector that will search for neutrinoless double beta decay (ßß0v) in 136XE at the Laboratorio Subterráneo de Canfranc (LSC), in Spain. The document formalizes the design presented in our Conceptual Design Report (CDR): an electroluminescence time projection chamber, with separate readout planes for calorimetry and tracking, located, respectively, behind cathode and anode. The detector is designed to hold a maximum of about 150 kg of xenon at 15 bar, or 100 kg at 10 bar. This option builds in the capability to increase the total isotope mass by 50% while keeping the operating pressure at a manageable level. The readout pla…
Identification of Cpgp40/15 Type Ib as the Predominant Allele in Isolates of Cryptosporidium spp. from a Waterborne Outbreak of Gastroenteritis in So…
2006
ABSTRACT Cryptosporidium sp. isolates from a waterborne outbreak of diarrhea in France were analyzed by PCR-restriction fragment length polymorphism analysis and sequencing of the Cpgp40/15 locus. Ninety-one percent of the isolates were Cryptosporidium hominis type Ib. The results of this study and those of studies of other outbreaks suggest that the type Ib allele is the predominant allele associated with waterborne cryptosporidiosis.
