Static Thermal Model Learning for High-Performance Multicore Servers
No full textAggressive thermal management is a critical feature for high-end computing platforms, as worst-case thermal budgeting is becoming unaffordable. Reactive thermal management, which sets temperature thresholds to trigger thermal capping actions, is too "near-sighted", and it may lead to severe performance degradation and thermal overshoots. More aggressive proactive thermal management minimizes performance penalty with smooth optimal control, but it requires the knowledge of the system thermal models to be precise. Unfortunately, in practice these models are not provided by equipment manufacturers, and they strongly depend on the deployment environment. Hence, we need to develop procedures to derive thermal models automatically in the field. In this paper, we focus on static thermal model learning. We tackle the problem in a real-life context: we developed a complete infrastructure for model-building and thermal data collection in the Linux environment, and we tested it on an Intel Nehalem-based server CPU. Model building is based on a least-square procedure which extracts the model linking power dissipation with temperature in steady-state conditions. Our results show high accuracy and robustness even in presence of a complex thermal environment and limited-precision power and temperature measurements typical of today's commercial servers
ANDREAS UNGARUS, Descripcio victorie Beneventi, edizione critica, introduzione, note e traduzione a cura di F. Delle Donne

L’operetta, di cui qui si fornisce una edizione critica assolutamente nuova (la prima completa), accompagnata da traduzione italiana, è la fonte più dettagliata sulla battaglia combattuta tra Manfredi di Svevia e Carlo I d’Angiò a Benevento il 26 febbraio 1266. Composta probabilmente nel 1282, in occasione dello scoppio dei Vespri Siciliani (anche se non possono essere escluse fasi redazioni precedenti), fornisce importantissime informazioni sulla battaglia che segnò un momento cruciale nella storia dell’Italia, dell’Impero, della Chiesa e quindi del mondo, perché mise fine al dominio della dinastia degli Hohenstaufen aprendo la strada all’affermazione della stirpe angioina, destinata a regnare, in Italia, per circa due secoli. Usando, infatti, e trascrivendo interamente alcune epistole inviate, nelle ore immediatamente successive alla conclusione della battaglia, da alcuni importanti protagonisti dello scontro bellico (tra questi lo stesso Carlo I d’Angiò), porta alla nostra conoscenza dettagli sostanziali sugli schieramenti in campo, sulle fasi del combattimento, sul ritrovamento, dopo alcuni giorni, del corpo di Manfredi.
Tuttavia, la Descripcio victorie Beneventi, ben scritta ed elaborata nello stile fiorito e ornato che caratterizza la prosa retorica del secolo che vide il trionfo dei dictatores, non esaurisce i motivi di interesse esclusivamente con la relazione sulla battaglia di Benevento, o con quella della federiciana porta di Capua, di cui pure viene offerta la prima accurata descrizione. Infatti, essa aggiunge una importante tessera al mosaico della cultura europea: quella retorico-letteraria e quella politico-propagandistica di un’epoca che, in seguito alla alterazione degli antichi equilibri, sprigionò quelle nuove energie, che, inarrestabilmente, avrebbero condotto all’Europa degli stati nazionali, i quali, al di fuori e talora contro l’Impero e la Chiesa, non sarebbero più stati disposti a riconoscere la superiorità di autorità egemoniche e assolute, ma, allo stesso tempo, troppo distanti e incorporee.
Usually neglected and often completely ignored, the Andreas Ungarus’ Descripcio victorie Beneventi undoubtedly must be rediscovered.
The chronicle, here presented in a fully new critical edition (the first complete), accompanied by Italian translation, is the most detailed source about the battle of Benevento (February 26 1266) between Manfred of Sicily and Charles of Anjou. Composed probably in 1282, at the beginning of the Sicilian Vespers (but we cannot exclude previous redactions), provides important information on the that battle, which marked a crucial moment in the history of Italy, of the Empire, of the Church and therefore of the world, because it represented the end of the rule of the Hohenstaufen dynasty and the the affirmation of the Angevins, destined to reign in Italy for about two centuries. The Descripcio uses and entirely transcribes some letters sent – in the hours immediately following the conclusion of the battle – by some important protagonists of the battle (among these the same Charles I of Anjou); so let us know substantial detail on the factions in the field, on the phases of the fight, on the discovery, after a few days, of the body of Manfred.
However, the Descripcio victorie Beneventi, well-written and drawn in the flowery and ornate prose that characterizes the rhetoric of the century which saw the triumph of the dictatores, does not exhaust his interest exclusively by reporting the battle of Benevento, or by accurately describing (for the first time) the bridge of Capua constructed by Frederick II. In fact, it adds an important piece to the mosaic of European culture: the rhetorical and literary culture, and the political and propagandistic culture of an era, in which the old balances were altered, and that gave off the new energies that led to the Europe of national states
Characterization and modelling of low-frequency noise in PCM devices
No full textLow-frequency noise in PCM devices is experimentally investigated providing a new physical model for the amorphous GST (Ge2Sb2Te5) material. Noise intensity is characterized and modelled as a function of bias, temperature and size. Findings from 1/f noise analysis are used to understand the drift mechanism of the amorphous state resistance
Involvement of endogenous gabaergic system in the modulation of gonadotropin secretion in normal cycling women.
No full textTo investigate whether endogenous GABA participates in the control of gonadotropin secretion during the menstrual cycle, placebo or sodium valproate (DPA), an anticonvulsant drug which enhances endogenous GABA content by blocking GABA degradation, were administered to regularly cycling women both during early follicular and midluteal phase. In a first set of experiments, the effect of DPA administration (400 mg, orally) on basal gonadotropin secretion was evaluated in 13 subjects. During early follicular phase (n = 6), no significant changes in plasma gonadotropin levels were observed after DPA or placebo administration. Conversely, during midluteal phase (n = 7), DPA administration resulted in a significant fall (p less than 0.01) in plasma LH concentrations, with a maximal percent decrease of 41.8 +/- 6.7% after 120 min. No changes in plasma FSH levels were observed. In a second set of experiments, the effect of DPA pretreatment (400 mg, orally) on gonadotropin release stimulated by a pulse of exogenous GnRH (10 micrograms, iv bolus) was studied in 11 subjects. During both follicular (n = 4) and luteal phase (n = 7), DPA did not modify gonadotropin response to GnRH injected 1h after pretreatment. Finally, 8 subjects were submitted to iv injection with 10 micrograms GnRH 2h after pretreatment with DPA (400 mg, orally) or placebo. During both follicular (n = 4) and luteal phase (n = 4), no statistical differences in gonadotropin response to GnRH were found between DPA and placebo pretreatment. These findings demonstrated that during the estrogen-progesterone (midluteal) phase of menstrual cycle, endogenous GABA is involved in the inhibitory regulation of LH secretion at a central level
Capillary zone electrophoresis and artificial neural networks for estimation of the postmortem interval (PMI) using electrolytes measurements in human vitreous humour.
No full textDetermination of electrolyte concentrations (mainly potassium) in vitreous humour has long been considered an important tool in human death investigations for the estimation of the post-mortem interval (PMI). On the basis of its well known potential in ion analysis, capillary zone electrophoresis (CZE) has recently been applied to achieve a rapid and simultaneous determination of inorganic ions in this extracellular fluid. In the present work, artificial neural networks (ANN) were applied for modelling of the relationship of multicomponent CZE analysis of K+, NH4+, Na+, and Ba2+ ions in vitreous humour with PMI. In a study based on 61 cases with different causes of death and a known PMI ranging from 3 to 144 h, the use of ANNs considering all inorganic ion data from the human vitreous humour, achieved a substantial improvement of post-mortem interval prediction. Good linear correlation was observed (r2 = 0.98) and in comparison to the traditional linear least squares (LLS) method applied only to K+ levels in the vitreous humour, the prediction of PMI with ANN was improved by a factor of 5 from ≈ ± 15 h to less than 3 h
Undifferentiated connective tissue diseases and adverse pregnancy outcomes : an undervalued association?
No full textUndifferentiated connective tissue diseases (UCTDs) are a heterogeneous group of disorders characterized by symptoms and signs suggestive of systemic autoimmune rheumatic disease (ARD), but which do not fulfill all the established criteria for definite diagnosis of a condition. Although a third of UCTDs can progress to a definite ARD within months or years, most UCTDs can remain stable for years with minimal disease activity. The annual incidence of UCTD in the general population ranges from 14 to 140 per 100 000 people. UCTDs are associated with the persistence of several circulating autoantibodies including antinuclear, antiphospholipid or antithyroid antibodies. Immunological evaluation of subjects with UCTDs suggests a proinflammatory state and dysregulation of the Th1/Th2 balance. Autoantibodies have well-known deleterious effects on placentation and have been associated with an increased risk of prematurity, fetal growth restriction (FGR), preeclampsia, and congenital atrioventricular heart block. Although epidemiological and biological data suggest a potential negative impact on reproductive outcomes, the relationship between UCTD and pregnancy outcomes has not been adequately studied. While awaiting definitive data from large studies, obstetricians should be aware that rheumatic disorders in their early, incomplete, or undifferentiated phases can adversely affect pregnancy outcomes, increasing the likelihood of pregnancy loss, FGR, preeclampsia, and prematurit
