Incidental PET/CT Findings of Suspected COVID-19 in a Region of High Prevalence.
We describe a case of suspected COVID-19 pneumonia in a 61-year-old male with known primary central nervous system diffuse large B-cell lymphoma (DLBCL) who underwent restaging PET/CT during the initial peak of infection of COVID-19 pneumonia within the New York region. At the time of his routine PET-CT to assess for disease progression, typical CT imaging features of COVID-19 pneumonia were identified. Upon further investigation, the patient was asymptomatic, and his infection status remained unknown. He was subsequently lost to follow-up with his COVID-19 status pending
Networks from gene expression time series: characterization of correlation patterns
This paper describes characteristic features of networks reconstructed from
gene expression time series data. Several null models are considered in order
to discriminate between informations embedded in the network that are related
to real data, and features that are due to the method used for network
reconstruction (time correlation).Comment: 10 pages, 3 BMP figures, 1 Table. To appear in Int. J. Bif. Chaos,

LATE FROST EVENTS IN AN ALPINE VALLEY: MEASUREMENTS AND CHARACTERISATION OF THE PROCESS
Under the research project GEPRI, aimed at investigating and characterizing late frost events potentiallydangerous for cultivated areas, in the spring of 2004 an intensive meteorological field experiment has been made in the Adige River Valley in Trentino (Northern Italy). The project is aimed at a better characterization of the mechanism of late frost events in complex topography in order to improve the forecast of the occurrence of nocturnal temperature minima. In this work some preliminary results of the micrometeorological measurements performed at a target area within an appletrees orchard are presented and discussed. Measurements allowed the determination of the complete energy balance, as well as the identification of specific local-scale circulations which appear to be relevant in characterizing the night-time cooling process. In case of fair weather conditions, the latter displays a sequence of at least four different phases which seem to alternate rather than superimpose advective- and radiative-effects
A bootstrap-based approach for sample size calculation when traditional estimations are not possible
Development of a measurement platformon a light airplane and analysis of airborne measurementsin the atmospheric boundary layer
In the present paper we provide an overview of a long term research project aimed at setting up a suitable platform
for measurements in the atmospheric boundary layer on a light airplane along with some preliminary results
obtained from fi eld campaigns at selected sites. Measurements of air pressure, temperature and relative humidity
have been performed in various Alpine valleys up to a height of about 2500 m a.m.s.l. By means of GPS resources
and specifi c post-processing procedures careful positioning of measurement points within the explored domain
has been achieved. The analysis of collected data allowed detailed investigation of atmospheric vertical structures
and dynamics typical of valley environment, such as morning transition from ground based inversion to fully
developed well mixed convective boundary layer. Based on data collected along fl ights, 3D fi elds of the explored
variables have been detected and identifi ed through application of geostatistical techniques (Kriging). The adopted
procedures allowed evaluation of the intrinsic statistical structure of the spatial distribution of measured quantities
and the estimate of the values of the same variable at unexplored locations by suitable weighted average of data
recorded at close locations. Results thus obtained are presented and discussed
A Non-equilibrium STM model for Kondo Resonance on surface
Based on a no-equilibrium STM model, we study Kondo resonance on a surface by
self-consistent calculations. The shapes of tunneling spectra are dependent on
the energy range of tunneling electrons. Our results show that both
energy-cutoff and energy-window of tunneling electrons have significant
influence on the shapes of tunneling spectra. If no energy-cutoff is used, the
Kondo resonances in tunneling spectrum are peaks with the same shapes in the
density of state of absorbed magnetic atoms. This is just the prediction of
Tersoff theory. If we use an energy cutoff to remove high-energy lectrons, a
dip structure will modulate the Kondo resonance peak in the tunneling spectrum.
The real shape of Kondo peak is the mixing of the peak and dip, the so-called
Fano line shape. The method of self-consistent non-equilibrium matrix Green
function is discussed in details.Comment: 11 pages and 8 eps figur
The use of carboxymethylcellulose for the tartaric stabilization of white wines, in comparison with other oenological additives
The aim of this study was to test the effectiveness of two types of carboxymethylcellulose (CMC), at different doses, for the prevention of tartaric precipitations in two white wines (Pinot Blanc and Chardonnay), in comparison with metatartaric acid and a commercial arabic gum. After the addition of the additives to the wines, the mini-contact test was carried out and the saturation temperature was determined by Ridomi’s method. The determination of the saturation temperature was then repeated on the same trials kept at -4 °C for 10 days. Both kinds of CMC caused a significant decrease in tartaric precipitations induced by the addition of potassium bitartrate (KHT) (mini-contact test), by limiting the growth of the added KHT crystals. Their effectiveness increased with the dose, following a hyperbolic trend. The stabilizing effect of the two kinds of CMC, particularly CMC2 (more viscous), was similar to the one of metatartaric acid. Their use must be considered complementary to the cold treatment (chillproofing).
