description: The activation of materials due to exposure to cosmic rays may become an important background source for experiments investigating rare event phenomena. DarkSide-20k, currently under construction at the Laboratori Nazionali del Gran Sasso, is a direct detection experiment for galactic dark matter particles, using a two-phase liquid-argon Time Projection Chamber (TPC) filled with 49.7 tonnes (active mass) of Underground Argon (UAr) depleted in 39Ar. Despite the outstanding capability of discriminating gamma/beta background in argon TPCs, this background must be considered because of induced dead time or accidental coincidences mimicking dark-matter signals and it is relevant for low-threshold electron-counting measurements. Here, the cosmogenic activity of relevant long-lived radioisotopes induced in the experiment has been estimated to set requirements and procedures during preparation of the experiment and to check that it is not dominant over primordial radioactivity; particular attention has been paid to the activation of the 120 t of UAr used in DarkSide-20k. Expected exposures above ground and production rates, either measured or calculated, have been considered in detail. From the simulated counting rates in the detector due to cosmogenic isotopes, it is concluded that activation in copper and stainless steel is not problematic. The activity of 39Ar induced during extraction, purification and transport on surface is evaluated to be 2.8% of the activity measured in UAr by DarkSide-50 experiment, which used the same underground source, and thus considered acceptable. Other isotopes in the UAr such as 37Ar and 3H are shown not to be relevant due to short half-life and assumed purification methods.

description: Faddeev formulation of general relativity (GR) is considered where the metric is composed of ten vector fields or a ten-dimensional tetrad. Upon partial use of the field equations, this theory results in the usual GR. Earlier we have proposed some minisuperspace model for the Faddeev formulation where the tetrad fields are piecewise constant on the polytopes like 4-simplices or, say, cuboids into which ${\rm I \hspace{-3pt} R}^4$ can be decomposed. Now we study some representation of this (discrete) theory, an analogue of the Cartan-Weyl connection-type form of the Hilbert-Einstein action in the usual continuum GR.

Limitation of Inverse Probability-of-Censoring Weights in Estimating Survival in the Presence of Strong Selection Bias

description: In time-to-event analyses, artificial censoring with correction for induced selection bias using inverse probability-of-censoring weights can be used to 1) examine the natural history of a disease after effective interventions are widely available, 2) correct bias due to noncompliance with fixed or dynamic treatment regimens, and 3) estimate survival in the presence of competing risks. Artificial censoring entails censoring participants when they meet a predefined study criterion, such as exposure to an intervention, failure to comply, or the occurrence of a competing outcome. Inverse probability-of-censoring weights use measured common predictors of the artificial censoring mechanism and the outcome of interest to determine what the survival experience of the artificially censored participants would be had they never been exposed to the intervention, complied with their treatment regimen, or not developed the competing outcome. Even if all common predictors are appropriately measured and taken into account, in the context of small sample size and strong selection bias, inverse probability-of-censoring weights could fail because of violations in assumptions necessary to correct selection bias. The authors used an example from the Multicenter AIDS Cohort Study, 1984–2008, regarding estimation of long-term acquired immunodeficiency syndrome-free survival to demonstrate the impact of violations in necessary assumptions. Approaches to improve correction methods are discussed.

description: Nel panorama della rappresentazione e della comunicazione visiva contemporanee, contraddistinto da repertori di linguaggi, prodotti, canali, tecniche, sempre pi� ampi e ibridi, si sta rilevando la crescente diffusione di forme espressive ?brevi?. Una brevit�, che si attua su pi� livelli: da quello sintattico (verbo-visivo), a quello lessicale, da quello temporale (relativo alla durata dell?esposizione del contenuto o della percezione) a quello spaziale, ecc.; una brevit� che intercetta fruitori sempre pi� eterogenei con finalit� che vanno dalla comunicazione istituzionale a quella promozionale, dalla comunicazione personale a quella sociale. Il progetto di ricerca, tenendo conto della letteratura sull'argomento, intende indagare le forme di comunicazione brevi nel particolare ambito dei social network, caratterizzati da palinsesti omnicanale in cui i confini tra prodotto e paratesto sono quanto pi� fluidi e mutevoli, con l?intenzione di indagare le caratteristiche comunicative e rappresentative di tale ?zona di confine?. Alla base di questo studio, l?idea che la soglia, il margine, e le forme di comunicazione in essa sviluppate, sia luogo di sperimentazione, ?una zona non solo di transizione, ma di transazione: luogo privilegiato di una pragmatica e di una strategia, di un?azione sul pubblico? (Genette, 1987), uno spazio in cui le commistioni da ambiti diversi possano dare vita ad interessanti produzioni, alimentando anche il rinnovamento dei linguaggi e dei processi d?uso della comunicazione. La ricerca intende quindi sistematizzare e analizzare le tendenze sviluppatesi nel corso degli ultimi anni che hanno visto un ampliarsi esponenziale della comunicazione, in termini di contenuti, processi, prodotti e canali, con l?obiettivo di individuare e le varianti e le invarianti che fanno di una comunicazione una comunicazione breve. La finalit� del progetto di ricerca � quella di contribuire alla sistematizzazione dei linguaggi, e dei processi dedicati a questo particolare ambito della comunicazione, auspicando di collaborare alla formazione di una cultura della rappresentazione e della comunicazione breve: da qui la volont� di sviluppare e studiare le forme brevi di comunicazione, quali possibili soluzioni per arrivare ad un pubblico eterogeneo nel minor tempo possibile.

description: Epidemiologic studies seldom include wealth as a component of socioeconomic status. The authors investigated the associations between wealth and 2 broad outcome measures: mortality and self-rated general health status. Data from the longitudinal Panel Study of Income Dynamics, collected in a US population between 1984 and 2005, were used to fit marginal structural models and to estimate relative and absolute measures of effect. Wealth was specified as a 6-category variable: those with ≤0 wealth and quintiles of positive wealth. There were a 16%–44% higher risk and 6–18 excess cases of poor/fair health (per 1,000 persons) among the less wealthy relative to the wealthiest quintile. Less wealthy men, women, and whites had higher risk of poor/fair health relative to their wealthy counterparts. The overall wealth–mortality association revealed a 62% increased risk and 4 excess deaths (per 1,000 persons) among the least wealthy. Less wealthy women had between a 24% and a 90% higher risk of death, and the least wealthy men had 6 excess deaths compared with the wealthiest quintile. Overall, there was a strong inverse association between wealth and poor health status and between wealth and mortality.

description: Regular physical activity is known to decrease the risk of cardiovascular disease, but the risk of ischemic stroke immediately following moderate or vigorous physical activity remains unclear. The authors evaluated the risk of acute ischemic stroke immediately following physical activity and examined whether the risk was modified by regular physical activity. In a multicenter case-crossover study, the authors interviewed 390 ischemic stroke patients (209 men, 181 women) at 3 North American hospitals between January 2001 and November 2006. Physical activity during the hour before stroke symptoms arose was compared with usual frequency of physical activity over the prior year. Of the 390 subjects, 21 (5%) reported having engaged in moderate or vigorous physical activity during the hour before ischemic stroke onset, and 6 subjects had lifted an object weighing at least 50 pounds (≥23 kg) during that hour. The rate ratio for ischemic stroke was 2.3 (95% confidence interval (CI): 1.5, 3.7; P < 0.001) for moderate or vigorous physical activity in the previous hour and 2.6 (95% CI: 1.1, 5.9; P = 0.02) for lifting 50 pounds or more. People who reported engaging in moderate or vigorous physical activity at least 3 times per week experienced a 2-fold increased risk (95% CI: 1.2, 3.3) with each bout of physical activity, as compared with a 6.8-fold risk (95% CI: 2.5, 18.8) among more sedentary subjects (P for homogeneity = 0.03).
The role of DEPDC5 in the pathogenesis of mTOR-dependent epilepsy and focal cortical dysplasia
Creators: name: DE FUSCO, ANTONIO
Publisher: name: Universit� degli studi di Genova
Year: 2020

description: DEP-domain containing 5 (DEPDC5) is part of the GATOR1 complex that functions as key inhibitor of the mechanistic target of rapamycin complex 1 (mTORC1) in the absence of amino acids. Mutations in DEPDC5 have been identified as the most common cause of either lesional or non-lesional focal epilepsy and are associated with mTOR hyperactivity. Recently, it has been hypothesized that somatic ?second-hit? mutations occur in the brain of patients with the more severe symptomatology, including focal cortical dysplasia type II, drug-resistant epilepsy and intellectual disability. However, the mechanisms underlying dysplastic and epileptic phenotype following DEPDC5 loss-of-function, especially at the cellular levels, are still largely unknown, particularly regarding the morpho-functional impact of DEPDC5 deficiency at level of synaptic connectivity and transmission. The scope of my PhD project is to investigate the pathological changes occurring with DEPDC5 loss-of-function, with particular emphasis on cellular and synaptic morphology and physiology, and to address the role of the loss of heterozygosity in DEPDC5-related pathogenesis. As the full knockout of Depdc5 is embryonically lethal in rodents, in this study I have first characterized a heterozygous knockout mouse (Depdc5+/-), which failed to recapitulate the major phenotypic tracts of the pathology, except for a reduced PTZ-induced epileptic threshold. Therefore, to uncover the phenotype induced by Depdc5 loss-of-function, I have compared the condition of the constitutive Depdc5+/- haploinsufficent mouse with the more effective acute neuronal knockdown of Depdc5 by RNA interference. While heterozygous Depdc5+/- neurons have a very mild phenotype with morpho-functional features that are not significantly different from wild type neurons, acutely knocked down neurons exhibit a much stronger phenotype characterized by mTOR hyperactivation, increased soma size and dendritic arborization, increased excitatory synaptic transmission and intrinsic excitability of excitatory neurons, leading to an excitation/inhibition imbalance. These results uncover a novel synaptic phenotype that is causally linked to acute Depdc5 knockdown and mTOR hyperactivity, highlighting the loss of heterozygosity as causal factor for the establishment of FCD-related neuronal phenotype, and suggesting an involvement of Depdc5 in the neurodevelopmental processes. The robust synaptic phenotype resulting from acute sh-mediated, but not constitutive, Depdc5 deficiency is reminiscent of the somatic second-hit mechanism in patients with focal cortical dysplasia and, together with the increased intrinsic excitability, can trigger the epileptogenic process.

description: Nutrition plays a critical role in maternal and fetal health; however, research on error in the measurement of energy intake during pregnancy is limited. The authors analyzed data on 998 women living in central North Carolina with singleton pregnancies during 2001–2005. Second-trimester diet was assessed by food frequency questionnaire. Estimated energy requirements were calculated using Institute of Medicine prediction equations, with adjustment for energy costs during the second trimester. Implausible values for daily energy intake were determined using confidence limits of agreement for energy intake/estimated energy requirements. Prevalences of low energy reporting (LER) and high energy reporting (HER) were 32.8% and 12.9%, respectively. In a multivariable analysis, pregravid body mass index was related to both LER and HER; LER was higher in both overweight (odds ratio = 1.96, 95% confidence interval: 1.26, 3.02; P = 0.031) and obese (odds ratio = 3.29, 95% confidence interval: 2.33, 4.65; P < 0.001) women than in normal-weight counterparts. Other predictors of LER included marriage and higher levels of physical activity. HER was higher among subjects who were underweight, African-American, and less educated and subjects who had higher depressive symptom scores. LER and HER are prevalent during pregnancy. Identifying their predictors may improve data collection and analytic methods for reducing systematic bias in the study of diet and reproductive outcomes.

description: The authors’ purpose was to expand sexually transmitted disease core theory by examining the roles of person, place, and time in differentiating geographic core areas from outbreak areas. The authors mapped yearly census-tract-level syphilis rates for San Francisco, California, based on new primary and secondary syphilis cases reported to the San Francisco City sexually transmitted disease surveillance program between January 1, 1985, and December 31, 2007. SaTScan software (Information Management Services, Inc., Silver Spring, Maryland) was used to identify geographic clusters of significantly elevated syphilis rates over space and time. The authors graphed epidemic curves for 1) core areas, 2) outbreak areas, 3) neither core nor outbreak areas, and 4) noncore areas, where noncore areas included outbreaks, and stratified these curves according to demographic characteristics. Five clusters of significantly elevated primary and secondary syphilis rates were identified. A 5-year threshold was useful for differentiating core clusters from outbreak clusters. Epidemic curves for core areas, outbreak areas, neither core nor outbreak areas, and noncore areas were perfectly synchronized in phase trends and wavelength over time, even when broken down by demographic characteristics. Between epidemics, the occurrence of syphilis affected all demographic groups equally. During an epidemic, a temporary disparity in syphilis occurrence arose and a homogeneous core group of cases could be defined.

description: —In this paper, a novel design method for chipless RFID tags in frequency domain has been introduced. The tags are designed based on letters and symbols, and printed on the cheap substrates, such as plastic and paper. These tags are part of a bigger system which uses Artificial Intelligence for decoding. This paper demonstrates the way to adjust the dimensions of the letters so that desired backscatter frequency response can be achieved. This work makes the implementation of cheap and flexible tags easier for the IoT application in the mm-wave band.
The issue of stereochemical control in multicomponent reactions and glycosylation processes.

Publisher: name: Universit� degli studi di Genova
Year: 2021

description: Multicomponent reactions (MCRs) are processes that show high atom and step economy; two different parts of my thesis were linked by MCRs. In the first part, levulinic acid was converted into a variety of bicyclic nitrogen heterocycles passing by an Ugi reaction. The obtained intermediate was then converted in the final product via a simple SN2 cyclization. The second part, instead, was dedicated to the obtainment of organo-catalysts structurally based on secondary and tertiary amine groups. First attempts, to get the latter in bicyclic structures, involved a starting MCR with L-prolinol, but the reaction showed low diastereoselectivity and the cyclization failed. A different strategy was aimed to obtain secondary amines and resulted to be more efficient. The involvement of a seven-membered cyclic imine, with a chiral center in C-3, in a Ugi-Joulli� reaction resulted in a very diastereoselective process. Using a silyl oxy derived carboxylic acid, an Ugi adduct with a protected alcohol is obtained. Thus, an intramolecular cyclization can be performed producing the final free amine group. The obtained amine was used to perform the first catalysis tests in Michael and aldol reactions. Although no catalytic activity was detected, different reaction conditions and structures have still to been tested. Finally, the reaction mechanism in self-promoted glycosylations was investigated. They involve a trichloroacetimidate as glycosyl donor which is activated by an acceptor that contains an acid sulfonamide portion. An alcoholic function was added to the acceptor with a consecutive possible production of both O- and N-glycosides. Dissociative mechanism favors the first while an associative mechanism brings to the second. The study showed the chemoselectivity and, to some extent, the stereoselectivity of the reaction to be controlled by tuning the parameters e.g. the polarity of the solvent, the concentration of donor and acceptor and the use of additives such as lithium salts.

description: Modified gravity and generalized second law (GSL) of thermodynamics are interesting topics in the modern cosmology. In this regard, we investigate the GSL of gravitational thermodynamics in the framework of modified Gauss-Bonnet gravity or f(G)-gravity. We consider a spatially FRW universe filled with the matter and radiation enclosed by the dynamical apparent horizon with the Hawking temperature. For two viable f(G) models, we first numerically solve the set of differential equations governing the dynamics of f(G)-gravity. Then, we obtain the evolutions of the Hubble parameter, the Gauss-Bonnet curvature invariant term, the density and equation of state parameters as well as the deceleration parameter. In addition, we check the energy conditions for both models and finally examine the validity of the GSL. For the selected f(G) models, we conclude that both models have a stable de Sitter attractor. The equation of state parameters behave quite similar to those of the LCDM model in the radiation/matter dominated epochs, then they enter the phantom region before reaching the de Sitter attractor with w=-1. The deceleration parameter starts from the radiation/matter dominated eras, then transits from a cosmic deceleration to acceleration and finally approaches a de Sitter regime at late times, as expected. Furthermore, the GSL is respected for both models during the standard radiation/matter dominated epochs. Thereafter when the universe becomes accelerating, the GSL is violated in some ranges of scale factor. At late times, the evolution of the GSL predicts an adiabatic behavior for the accelerated expansion of the universe.

La r�ception d'Andr� Gide dans la presse italienne (1895-1947)

description: This study focuses Andr� Gide?s reception in the Italian press, starting from 1895, date of the first mention of the author?s name in a periodical, up to 1947, when he was awarded with the Nobel Prize. This long period is characterised by significant historical changes which profoundly affected the world of culture and literature in Europe and, more particularly, in Italy. Between the end of the 19th century to the second post-war period, two world conflicts, twenty years of dictatorship and a civil war led to an evolution of the Italian society, culture and literature. All these changes represent the historical background of Gide?s reception. Leading public figure and great European, Gide cultivates a preferential relationship with Italy; at first, this country is the destination of his first trips and, a short while afterward, a place of work and of dialogue with the local intelligentsia. The considerable presence of the author in the Italian newspapers and magazines reflects the importance of his works in Italy. My work consisted in two different phases. First, the researching phase, in which I gathered articles and unpublished materials to trace Gide?s presence in the Italian cultural network. Second, the analysing phase, in which I studied the whole material from a critical perspective. The two world wars mark two periods of difficulty in the cultural contacts within Europe and determine the irreversible change of the panorama of the following years. For this reason, I decided to draw up a chronological partition, based on the evolution of the receiving country. I divided my study into three periods: the first one lasts from 1895 to the end of the First World War (1918); the second one, from 1919 to 1943, covers the interwar period and the beginning of the Second World War; the third one, is from the end of fascism (1943) to 1947. Through the analysis of the Italian articles devoted to Gide, which constitute my primary corpus, I will define the critical perspective of Italian intellectuals about the French writer. At the same time, the precise definition of the author?s historical and biographical relations with Italy will be essential to draw a panorama of cross-relations: the interest of Italian intellectuals in contemporary French literature overlaps with Gide?s interest in Italian culture and literature.

description: Hemodialysis patients who live at high altitude use less exogenous erythropoietin but achieve higher hematocrit levels than those living at a lower altitude. The authors hypothesized that the effect of altitude would be strongest in hemodialysis patients with poor anemia treatment response. To explore this hypothesis, they studied anemia-related outcomes in US hemodialysis patients who move to higher altitudes. Using Medicare and US Geological Survey data, in 1992–2004 they identified instances in which a patient moved from a dialysis center at an altitude of <2,000 feet (600 m) to one at a higher elevation. Of these moves, 5,274 were ≥3,000 feet (900 m; the altitude group) and 25,345 were 250–500 feet (75–150 m; the control group). Among patients with poor treatment response at baseline, large increases in hematocrit and decreases in erythropoietin dosing were observed in the altitude relative to the control group. At 6 months, hematocrit had increased more in the altitude group (5.1%, 95% confidence interval (CI): 4.1, 6.2 vs. 3.7%, 95% CI: 3.5, 3.9), and erythropoietin dosing decreased more (4,600 units/week, 95% CI: 500, 8,700 vs. 1,700 units/week, 95% CI: 1,000, 2,400). No effect of altitude was observed in patients with better treatment response at baseline. These results support the hypothesis that altitude-induced hypoxia reduces erythropoietin requirements in hemodialysis patients with treatment-refractory anemia.

description: Superati �novant?anni d?impazienza� e dopo un lungo periodo votato all?autocommento e all?esplorazione delle proprie intenzioni, Raffaele La Capria ha raccolto le sue opere in due Meridiani curati da Silvio Perrella. La Capria ne ha celebrato l?uscita nella prolusione inaugurale di Salerno Letteratura, poi confluita nel breve autoritratto narrativo "Introduzione a me stesso" (2014). In questa sede, l?autore � tornato su alcuni punti essenziali della sua riflessione sulla scrittura, come la relazione, reciproca e ineludibile, fra tradizione e contemporaneit�. All?epilogo del �romanzo involontario� di una vita, La Capria guarda retrospettivamente alla propria esperienza come ad un?autentica educazione intellettuale. Perci�, muovendo da un?intervista inedita del 2015, riportata integralmente in appendice, la tesi ha l?obiettivo di ricostruire l?apprendistato letterario di La Capria dai primi anni Trenta, quando l?autore ancora frequentava il ginnasio, fino all?inizio dei Sessanta, quando ottenne il premio che ne avrebbe assicurato il successo. Il percorso, che riesamina l?intera bibliografia lacapriana nella sua variet� e nella sua stratificazione, si articola in una serie di fasi interdipendenti: la partecipazione indiretta alle iniziative dei GUF (intorno alle riviste �IX maggio� e �Pattuglia�); l?incursione nel giornalismo e l?impegno culturale nell?immediato dopoguerra (sulle pagine di �Latitudine� e di �SUD�); l?attivit� di traduttore dal francese e dall?inglese (da Andr� Gide a T.S. Eliot); l?impiego alla RAI come autore e conduttore radiofonico (con trasmissioni dedicate a Orwell, Stevenson, Saroyan e Faulkner); la collaborazione con �Il Gatto Selvatico�, la rivista dell?ENI voluta da Enrico Mattei e diretta da Attilio Bertolucci; e le vicende editoriali dei suoi primi due romanzi, ?Un giorno d?impazienza? (1952) e ?Ferito a morte? (1961), fino alla conquista dello Strega. La rilettura dell?opera di uno scrittore semi-autobiografico come La Capria, attraverso il costante riscontro di fonti giornalistiche, testimonianze epistolari e documenti d?archivio che avvalorano e occasionalmente smentiscono la sua versione dei fatti, diventa allora un?occasione per immergersi nella sua mitografia personale e avventurarsi in territori finora poco esplorati: come la ricostruzione del suo profilo culturale, a partire dal milieu in cui La Capria vive e opera, o l?incidenza delle letture e delle esperienze giovanili sulla sua prassi letteraria.

description: Ultralong-range Rydberg molecules (ULRM) are highly imbalanced bound systems formed via the low-energy scattering of a Rydberg electron with a ground-state atom. We investigate for $^{23}$Na the $d$-state and the energetically close-by trilobite state, exhibiting avoided crossings that lead to the breakdown of the adiabatic Born-Oppenheimer (BO) approximation. We develop a coupled-channel approach to explore the non-adiabatic interaction effects between these electronic states. The resulting spectrum exhibits stark differences in comparison to the BO spectra, such as the existence of above-threshold resonant states without any adiabatic counterparts, and a significant rearrangement of the spectral structure as well as the localization of the eigenstates. Our study motivates the use of $^{23}$Na ULRM, as a probe to explore vibronic interaction effects on exaggerated time and length scales.

To improve the number of trapped atoms, we broaden the cooling light spectrum to 102 MHz composed of seven frequency components and then trap atoms with a number of $6.0\times10^8$ which is about 4 times compared to that in the single-frequency cooling. The capture velocity and dependence of atomic number on the laser detuning have been analyzed, where the experimental result has a good agreement with the theoretical prediction based on a simple two-level model. We also analyze the loss rate of alkali metals due to fine-structure exchanging collisions and find that the multiple-sideband cooling is special valid for lithium.

description: Genetic studies have identified thousands of variants associated with complex traits. However, most association studies are limited to populations of European descent and a single phenotype. The Population Architecture using Genomics and Epidemiology (PAGE) Study was initiated in 2008 by the National Human Genome Research Institute to investigate the epidemiologic architecture of well-replicated genetic variants associated with complex diseases in several large, ethnically diverse population-based studies. Combining DNA samples and hundreds of phenotypes from multiple cohorts, PAGE is well-suited to address generalization of associations and variability of effects in diverse populations; identify genetic and environmental modifiers; evaluate disease subtypes, intermediate phenotypes, and biomarkers; and investigate associations with novel phenotypes. PAGE investigators harmonize phenotypes across studies where possible and perform coordinated cohort-specific analyses and meta-analyses. PAGE researchers are genotyping thousands of genetic variants in up to 121,000 DNA samples from African-American, white, Hispanic/Latino, Asian/Pacific Islander, and American Indian participants. Initial analyses will focus on single nucleotide polymorphisms (SNPs) associated with obesity, lipids, cardiovascular disease, type 2 diabetes, inflammation, various cancers, and related biomarkers. PAGE SNPs are also assessed for pleiotropy using the “phenome-wide association study” approach, testing each SNP for associations with hundreds of phenotypes. PAGE data will be deposited into the National Center for Biotechnology Information's Database of Genotypes and Phenotypes and made available via a custom browser.

description: Uno de los aspectos más importantes en la enseñanza-aprendizaje de una lengua extranjera es el léxico. El diccionario monolingüe es una herramienta útil para la enseñanza de este, pues en él se hallan significados, información gramatical, cultural y pragmática, que permiten ilustrar el sentido del término, además de guiar al uso del mismo. Sin embargo, el diccionario monolingüe es poco usado el aula ELE por varias razones: la creencia de que el diccionario solo brinda significados, la escasez de diccionarios monolingües para ELE y la poca adecuación de los diccionarios existentes. Ante esto se pueden buscar soluciones como la implementación de unidades didácticas que impliquen el uso del diccionario y la creación de un DMA que se ajuste a las necesidades de los usuarios.

description: Few studies have examined the associations between dietary patterns and head and neck squamous cell carcinoma (SCC) or whether they differ by race. This was evaluated using data from a population-based case-control study (2002–2006) including 1,176 cases of head and neck SCC and 1,317 age-, race-, and gender-matched controls from central and eastern North Carolina whose diets had been assessed by food frequency questionnaire. Factor analysis identified 2 patterns of intake: 1) high consumption of fruits, vegetables, and lean protein and 2) high consumption of fried foods, high-fat and processed meats, and sweets. Associations were estimated using logistic regression, adjusting for matching factors and confounders. Heterogeneity by tumor site (oral/pharyngeal vs. laryngeal) and effect-measure modification were also evaluated. Reduced odds of head and neck SCC were found for the fruit, vegetable, and lean protein pattern (for highest quartile vs. lowest, odds ratio = 0.53, 95% confidence interval: 0.39, 0.71). The fried foods, high-fat and processed meats, and sweets pattern was positively associated only with laryngeal cancer (odds ratio = 2.12, 95% confidence interval: 1.21, 3.72). These findings underline the importance of a dietary pattern rich in fruits and vegetables and low in high-fat and processed meats and sweets for prevention of head and neck cancer.

description: Bayesian posterior parameter distributions are often simulated using Markov chain Monte Carlo (MCMC) methods. However, MCMC methods are not always necessary and do not help the uninitiated understand Bayesian inference. As a bridge to understanding Bayesian inference, the authors illustrate a transparent rejection sampling method. In example 1, they illustrate rejection sampling using 36 cases and 198 controls from a case-control study (1976–1983) assessing the relation between residential exposure to magnetic fields and the development of childhood cancer. Results from rejection sampling (odds ratio (OR) = 1.69, 95% posterior interval (PI): 0.57, 5.00) were similar to MCMC results (OR = 1.69, 95% PI: 0.58, 4.95) and approximations from data-augmentation priors (OR = 1.74, 95% PI: 0.60, 5.06). In example 2, the authors apply rejection sampling to a cohort study of 315 human immunodeficiency virus seroconverters (1984–1998) to assess the relation between viral load after infection and 5-year incidence of acquired immunodeficiency syndrome, adjusting for (continuous) age at seroconversion and race. In this more complex example, rejection sampling required a notably longer run time than MCMC sampling but remained feasible and again yielded similar results. The transparency of the proposed approach comes at a price of being less broadly applicable than MCMC.
La categoria cristologica nello sviluppo del pensiero di Teodorico Moretti-Costanzi

description: Martino Bozza, nella ricostruzione genetica del pensiero di Moretti-Costanzi, non manca mai di riconoscere, nel maturarsi del pensiero morettiano, i segni di una francescanit�, di una ?umbriet�?, costitutive e originarie. In effetti � nel francescanesimo che il pensiero del maestro si � alimentato e ha trovato estensione nel confronto decisivo con le questioni dell?ontologia e della metafisica contemporanea. Il filosofo umbro trov� subito il modo di sciogliere e risolvere in chiave cristiana il carabellesiano �problema teologico come filosofia�; e soprattutto seppe riconoscere il carattere ?ascetico? della filosofia anche in dialogo con voci rilevanti della filosofia contemporanea come Martin Heidegger. Pochi come il filosofo umbro si sono saputi aprire con arditezza e radicalit� al dialogo con la filosofia contemporanea proponendo una tale particolare visione di una filosofia ?mistica? e ?pura?.

Forma breve e narrazione a cornice: le 'serate' o 'veglie' nella prosa russa (1770-1840)

description: Nella sua "Poetica storica della novella" Eleazar Meletinskij mette la questione della narrazione a cornice in relazione, pi� che con il genere novellistico, col tema della ciclizzazione e della formazione del romanzo di vita quotidiana. Rovesciando i termini della questione, ci si pu� chiedere se le peculiarit� della struttura narrativa a cornice, in particolare i suoi meccanismi metatestuali e comunicativi, possano fornire elementi utili alla comprensione della specificit� e delle funzioni della forma narrativa breve nella letteratura moderna, in particolare in relazione al suo antagonismo con la forma ?lunga? romanzesca. La presente ipotesi prende spunto da una tipologia di narrazione a cornice organizzata in ?serate? (in russo 've?era') ? un clich� presente in differenti letterature nazionali di epoche diverse ? che tra gli anni Settanta del Settecento e la fine degli anni Trenta dell?Ottocento riscuote ampio successo nella cultura letteraria russa. La ripresa, in un momento cruciale per la formazione della moderna prosa russa, di una struttura narrativa dalle ascendenze antiche, fortemente connotata dal punto di vista del ?genere?, evidenzia come l?utilizzo al suo interno della forma breve si apra alle pi� svariate contaminazioni e rielaborazioni, giocando un ruolo essenziale nella preparazione della grande stagione romanzesca.

description: We assess the potential of two-terminal graphene-hBN-graphene resonant tunneling diodes as high-frequency oscillators, using self-consistent quantum transport and electrostatic simulations to determine the time-dependent response of the diodes in a resonant circuit. We quantify how the frequency and power of the current oscillations depend on the diode and circuit parameters including the doping of the graphene electrodes, device geometry, alignment of the graphene lattices, and the circuit impedances. Our results indicate that current oscillations with frequencies of up to several hundred GHz should be achievable.
