Dataset of night-time emissions of the Earth in the near UV range (290-430 nm), with 6.3 km resolution in the latitude range -51.6

The data presented in this article are related to the research paper entitled "Observation of night-time emissions of the Earth in the near UV range from the International Space Station with the Mini-EUSO detector" (Remote Sensing of Environment, Volume 284, January 2023, 113336, https://doi.org/10.1016/j.rse.2022.113336). The data have been acquired with the Mini-EUSO detector, an UV telescope operating in the range 290-430 nm and located inside the International Space Station. The detector was launched in August 2019, and it has started operations from the nadir-facing UV-transparent window in the Russian Zvezda module in October 2019. The data presented here refer to 32 sessions acquired between 2019-11-19 and 2021-05-06. The instrument consists of a Fresnel-lens optical system and a focal surface composed of 36 multi-anode photomultiplier tubes, each with 64 channels, for a total of 2304 channels with single photon counting sensitivity. The telescope, with a square field-of-view of 44°, has a spatial resolution on the Earth surface of 6.3 km and saves triggered transient phenomena with a temporal resolution of 2.5 µs and 320 µs. The telescope also operates in continuous acquisition at a 40.96 ms scale. In this article, large-area night-time UV maps obtained processing the 40.96 ms data, taking averages over regions of some specific geographical areas (e.g., Europe, North America) and over the entire globe, are presented. Data are binned into 0.1° × 0.1° or 0.05° × 0.05° cells (depending on the scale of the map) over the Earth's surface. Raw data are made available in the form of tables (latitude, longitude, counts) and .kmz files (containing the .png images). These are - to the best of our knowledge - the highest sensitivity data in this wavelength range and can be of use to various disciplines.

New Direct Limit on Neutrinoless Double Beta Decay Half-Life of

The Cryogenic Underground Observatory for Rare Events (CUORE) at Laboratori Nazionali del Gran Sasso of INFN in Italy is an experiment searching for neutrinoless double beta (0νßß) decay. Its main goal is to investigate this decay in ^{130}Te, but its ton-scale mass and low background make CUORE sensitive to other rare processes as well. In this Letter, we present our first results on the search for 0νßß decay of ^{128}Te, the Te isotope with the second highest natural isotopic abundance. We find no evidence for this decay, and using a Bayesian analysis we set a lower limit on the ^{128}Te 0νßß decay half-life of T_{1/2}>3.6×10^{24} yr (90% CI). This represents the most stringent limit on the half-life of this isotope, improving by over a factor of 30 the previous direct search results, and exceeding those from geochemical experiments for the first time.

Influence of silicon morphology on direct current plasma electrolytic oxidation process in AlSi10Mg alloy produced with laser powder bed fusion.

In this work, plasma electrolytic oxidation (PEO) process was applied on AlSi10Mg samples, produced with laser powder bed fusion (L-PBF), in the as printed condition and after different heat treatments, and, for comparison, on as-cast samples of AlSi10Mg. PEO process was performed in direct-current mode using high current densities and short time in a basic silicate electrolyte. For the first time, the effects of silicon morphology in L-PBF AlSi10Mg samples, in as printed condition and after different heat treatments, on the obtained PEO coating were investigated in terms of microstructure and corrosion properties. The microstructure of the substrate was characterized with optical and electron microscopy observations (optical microscopy OM, scanning electron microscopy SEM, and transmission electron microscopy TEM) and with X-ray diffraction (XRD). The analysis showed that heat treatments of annealing and solution treating modified the morphology and distribution of silicon in the samples obtained through L-PBF. The PEO coated samples were characterized with SEM, both on the surface and in the cross-section, and compositional analysis were performed with energy dispersive spectroscopy (EDS) analysis and elemental mapping. The coatings were also analyzed with XRD and the corrosion properties evaluated through electrochemical impedance spectroscopy (EIS) tests. Also microhardness tests were performed on the substrates and on the coatings. The microstructure of the coatings was strongly influenced by the silicon distribution. In particular, a non-uniform distribution of silicon and the presence of iron-rich intermetallic (obtained in the as-cast and solution treated samples) induced the formation of more porous and thinner coatings in comparison with the ones obtained in the as printed and annealed samples. The not-uniform silicon distribution produced a not-homogenous distribution of silicon into the coatings. The particular cellular structure of the as printed sample induced the formation of a coating with a higher amorphous fraction, in comparison with the ones produced on the other samples. The higher thickness and lower porosity of the coatings obtained on the annealed and as printed samples resulted in an increase of the corrosion resistance.

Measurement of the 2νßß Decay Half-Life of

We measured two-neutrino double beta decay of ^{130}Te using an exposure of 300.7 kg yr accumulated with the CUORE detector. Using a Bayesian analysis to fit simulated spectra to experimental data, it was possible to disentangle all the major background sources and precisely measure the two-neutrino contribution. The half-life is in agreement with past measurements with a strongly reduced uncertainty: T_{1/2}^{2ν}=7.71_{-0.06}^{+0.08}(stat)_{-0.15}^{+0.12}(syst)×10^{20} yr. This measurement is the most precise determination of the ^{130}Te 2νßß decay half-life to date.

Real-life efficacy and safety of Ustekinumab as second- or third-line therapy in Crohn's disease: results from a large Italian cohort study.

OBJECTIVE: Ustekinumab (UST) is an anti-IL12/23 antibody for the treatment of Crohn's Disease (CD). The aim of this study was to compare the efficacy and safety of UST in a large population-based cohort of CD patients who failed previous treatment with other biologics. PATIENTS AND METHODS: 194 CD patients (108 males and 86 females, mean age 48 years (range 38-58 years) were retrospectively reviewed. 147 patients were already treated with anti-TNFα (75.8%), and 47 (24.2%) patients were already treated with anti-TNFα and vedolizumab. Concomitant treatment with steroids was present in 177 (91.2%) patients. RESULTS: At week 12, clinical remission was achieved in 146 (75.2%) patients. After a mean follow-up of 6 months, clinical remission was maintained in 135 (69.6%) patients; at that time, mucosal healing was assessed in 62 (31.9%) patients, and it was achieved in 33 (53.2) patients. Three (1.5%) patients were submitted to surgery. Steroid-free remission was achieved in 115 (59.3%) patients. Both serum C-Reactive Protein and Fecal Calprotectin (FC) levels were significantly reduced with respect to baseline levels during follow-up. A logistic regression, UST therapy as third-line therapy (after both anti-TNFα and vedolizumab), FC >200 µg/g, and HBI ≥8 were significantly associated with lack of remission. Adverse events occurred in 5 (2.6%) patients, and four of them required suspension of treatment. CONCLUSIONS: UST seemed to be really effective and safe in CD patients unresponsive to other biologic treatments, especially when used as second-line treatment.

Improved Limit on Neutrinoless Double-Beta Decay in

We report new results from the search for neutrinoless double-beta decay in ^{130} Te with the CUORE detector. This search benefits from a fourfold increase in exposure, lower trigger thresholds, and analysis improvements relative to our previous results. We observe a background of (1.38±0.07)×10^{-2} counts/(keV kg yr)) in the 0νßß decay region of interest and, with a total exposure of 372.5 kg yr, we attain a median exclusion sensitivity of 1.7×10^{25} yr. We find no evidence for 0νßß decay and set a 90% credibility interval Bayesian lower limit of 3.2×10^{25} yr on the ^{130} Te half-life for this process. In the hypothesis that 0νßß decay is mediated by light Majorana neutrinos, this results in an upper limit on the effective Majorana mass of 75-350 meV, depending on the nuclear matrix elements used.

Inflammatory bowel disease (IBD) position statement of the Italian Society of Colorectal Surgery (SICCR): general principles of IBD management.

The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of inflammatory bowel disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the general principles of surgical treatment of inflammatory bowel disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Resting state functional magnetic resonance imaging in attention deficit hyperactivity disorder. / Resonancia magnética funcional de reposo en el trastorno por déficit de atención e hiperactividad.

OBJECTIVE: To explore whether children and adolescents with attention deficit/hyperactivity disorder (ADHD) have altered the functional connectivity between the executive control network and the default mode network. METHODS: Exploratory study of a diagnostic test, prospective, case and control design. A total of 56 participants were recruited consecutively (29 inattentive or combined ADHD subtype and 27 controls) between 7 and 16 years old, male, right dominance. DSM-5 was applied as reference test and a battery of neuropsychological tests to confirm the diagnosis and assess comorbidities. Resting state functional magnetic resonance imaging was performed as an index test. The application and evaluation of the tests was blind. The brain regions were chosen a priori and the region of interest technique was used. The functional connectivity of the anterior cingulate cortex (ACC) was evaluated with: the precuneus (P), the posterior cingulate cortex (PCC) and the dorsomedial prefrontal cortex (DMPC). RESULTS: The functional connectivity in each of the associations evaluated in the patients with ADHD compared with the controls were: P_D=0.41 vs 0.44; CCP_D=0.43 vs 0.53; CPDM_D=0.75 vs. 0.79; P_I=0.40 vs 0.41; CCP_I=0.48 vs 0.53; CPDM_I=0.76 vs. 0.72). D: right side I: left side. Value of p> 0.05. CONCLUSION: Cerebral functional connectivity at rest is lower in ADHD patients when compared with healthy controls, however, the difference was not statistically significant.

Formation of stromatolite lamina at the interface of oxygenic-anoxygenic photosynthesis.

In modern stromatolites, mineralization results from a complex interplay between microbial metabolisms, the organic matrix, and environmental parameters. Here, we combined biogeochemical, mineralogical, and microscopic analyses with measurements of metabolic activity to characterize the mineralization processes and products in an emergent (<18 months) hypersaline microbial mat. While the nucleation of Mg silicates is ubiquitous in the mat, the initial formation of a Ca-Mg carbonate lamina depends on (i) the creation of a high-pH interface combined with a major change in properties of the exopolymeric substances at the interface of the oxygenic and anoxygenic photoautotrophic layers and (ii) the synergy between two major players of sulfur cycle, purple sulfur bacteria, and sulfate-reducing bacteria. The repetition of this process over time combined with upward growth of the mat is a possible pathway leading to the formation of a stromatolite.

Blood urea impairs brachial artery flow mediated dilation.

AIM: Urea, the main product of protein catabolism, is a biochemical marker of renal function. Though it is known that serum urea impairs vascular health, the relationship between its concentration and vascular reactivity in vivo has not been explored. Our study was undertaken to investigate possible association between serum urea and endothelial function in subjects without chronic kidney disease (CKD). METHODS: Eighty free-living subjects with serum creatinine ≤1 mg/dL and without CKD were enrolled for the present study. Serum analyses and evaluation of endothelial function were performed in all subjects. Endothelial function was measured using the flow-mediated dilation (FMD) technique. Simple and multiple regression analyses were used to test the association between FMD and considered variables. RESULTS: In correlation analyses FMD was found directly associated with HDL cholesterol (r=0.21; P=0.05) and eGFR (r=0.25; P=0.02) and inversely associated with age (r=-0.26; P=0.02), serum urea (r=-0.37; P<0.01), serum creatinine (r=-0.31; P<0.01) and brachial artery baseline diameter (r=-0.41; P<0.01). In multiple regression analysis only baseline artery diameter and serum urea predicted FMD; age, gender and cardiovascular risk factors did not relate with FMD. CONCLUSION: Our study demonstrates the association between serum urea and FMD, suggesting that the accumulation of waste products of protein metabolism may impair vascular health in subjects without CKD.

The use of "2-octyl cyanoacrylate" as skin adhesive in pediatric and congenital cardiac surgery.

AIM: The aim of this paper was to evaluate the safety and cost-effectiveness of "2-octyl-cyanoacrylate" as skin adhesive in congenital heart surgery. METHODS: From April 2010 to December 2011, we collected data from 300 patients who underwent cardiac surgery for congenital heart disease. We divided our population into 3 groups: group-1 (N.=100):"2-octyl-cyanoacrylate" has been used to replace the intra-dermal suture line; group-2 (N.=100):"2-octyl-cyanoacrylate" has been utilized as a barrier ("add-on measure") in addition to the intra-dermal suture line, group-3 (N.=100) with a standard intra-dermal suture line. RESULTS: Median age of patients was 1.36 years. One-hundred and thirty-nine patients were younger than 12 months and 56 older than 16 years. There were 11 wound dehiscence (3.6%) (2 in group-1 and 9 in group-3, P=0.001) and 1 superficial wound infection (group-1). Six patients (2%) required surgical wound revision (2 in group-1 and 4 in group-3, P=NS). Wound complication was significantly associated to delayed sternal closure (3/12 patients, 25% versus 13/288 patients, 4.5%) (P=0.04). Median cost (intra-/postoperative) for wound treatment was lower in group-1 and 2 (19±5.5 and 23.9±7.4 € respectively) when compared to Group-3 (26.7±3.2) (P<0.0001). CONCLUSION: The use of "2-octyl-cyanoacrylate" proved to be safe and effective; the "add-on measure" strategy provided the best cost-effective solution.

Preliminary evaluation of the tactile feedback system based on artificial skin and electrotactile stimulation.

This research is motivated by the need of integrating cutaneous sensing into a prosthetic device, enabling a bidirectional communication between the amputee and the prosthetic limb. An electronic skin based on piezoelectric polymer sensors transduces mechanical contact into electrical response which is conveyed to the human subject by electrotactile stimulation. Rectangular electrode arrays are placed on each patient's forearm and experiments are conducted on five different subjects to determine how well the orientation, position and direction of single lines are recognized. Overall, subjects discriminate the different touch modalities with acceptable success rates. In particular, the direction is identified at best and longitudinal lines on the patient's skin are recognized with the highest success rates. These preliminary results assess the feasibility of the artificial skin - electrostimulation system for prosthetic applications.

On the role of low-permeability beds in the acquisition of F and SO4 concentrations in a multi-layer aquifer, South-West France.

Fluoride (F(-)) commonly threatens groundwater quality. This is the case around the city of Bordeaux (France), where numerous wells tapping the thick and complex Eocene aquifer are contaminated by fluoride, which presents an issue for drinking water supply. The joint analysis of the spatial distribution of fluoride with other species like sulfate suggests that concentrations are mainly related to the occurrence of low-permeability layers containing evaporites or fluorite deposits. In order to identify the origin of the observed concentrations, a radial flow and transport model is implemented at the borehole scale. The hydraulic conductivity of the low-permeability layers and the vertical dispersivity of the aquifer were optimized to match the observed values of sulfate and fluoride concentrations. Interestingly, each of these parameters influences differently the simulated concentrations. This model has been successfully implemented to a neighboring well with the same parameter values, which tests the approach. The major conclusions drawn are: (i) the contamination in fluoride originates from the low-permeability layers, (ii) every low-permeability layer intercepted by the well releases fluoride (iii) Contamination not only originates from pore water of low-permeability layers, but may persist with long-term pumping due to mineral dissolution. As a consequence, fluoride contamination is likely to persist for a long time and the only solution to reduce fluoride concentration in abstracted water is to seal well screens facing low-permeability layers.

Time course analysis of brachial artery flow mediated dilatation in subjects with gingival inflammation.

AIM: Several investigations report an inverse association between periodontal disease and endothelial function measured by brachial artery Flow-Mediated-Dilatation (FMD) technique. These studies examined endothelial function by using the traditional approach to FMD calculation, that is from diameters assessed at 60 seconds after deflation. Nevertheless, possible relationship between gingival inflammation and endothelial dysfunction observed over this temporal threshold remains still unexplored. The purpose of our study was to explore the relationship between gingival inflammation and endothelial function, by considering the time course of brachial FMD. METHODS: Forty-six free-living white subjects, participating in a cardiovascular disease prevention campaign, were enrolled. FMD was measured at 60s and at 2 and 3 min after forearm ischemia. Maximal FMD was calculated (Peak FMD), for each patient. Gingival Index (GI) was evaluated as measure of gingival inflammation. RESULTS: In univariate analyses, GI was associated with both FMD at 60 sec (r=-0.30, P=0.038) and Peak FMD (r=-0.41, P=0.004). In multiple regression analyses including GI, age, gender, and known risk factors for atherosclerosis, only GI and age were independently and inversely associated with Peak FMD and FMD at 60 s, but this association was stronger with Peak FMD. Moreover, when we divided subjects on the basis of GI value, patients with GI > 1 presented lower Peak FMD and higher prevalence of absent FMD. CONCLUSION: The present study extends previous observations about the negative effects of periodontal disease on endothelial function, highlighting the importance of the evaluation of time course of vascular reactivity.
