Deadly Simulacra

Language and Semiotic Studies 2015年第3期1卷 130-138页

作者： massimo leone University of Turin

Taking the lead from a tale by French writer Prosper Mérimée,narrating the terrifying story of a statue of Venus that suddenly—and tragically—becomes alive,the paper will dwell on the several versions of this narrative topos(William of Malmesbury in the 12th Century,Gautier de Coincy in the 13th,Hermann Kroner in the 15th,up to Richard Burton in the 17th,Joseph von Eichendorff in the 19th,Gabriele D’Annunzio in the 20th)in order to semiotically refl ect on two streams of the human imaginary:on the one hand,the statue that becomes alive;on the other hand,the human being that becomes a *** such historical,anthropological,and semiotic excursus,the paper will conclude with an in-depth analysis of a very common present-day urban performance:living *** with reference to contemporary British novel Observatory Mansions,by Edward Carey,the paper will seek to answer the following questions:why is the spectacle of the human body that becomes like stone so fascinating?Why are spectators attracted by immobility and yet offer their coins in order to see it turn into movement and life again?

The article shows that,in the effort to convey a notion of the singularity of the beloved face,especially in tragic settings,often human cultures resort to nature,and adopt animal,vegetable,and even mineral metaphors in order to rhetorically transfer the singularity of their shapes to that of the facial *** trend develops across cultures in world literature but imposes itself with particular emphasis in those traditions,authors,and texts that posit a systematic correlation between the microcosmos and the macro-cosmos,between body and nature,and between the face and the landscape.

本文首先定义了随机性的三种类型:本体论随机性、现象学随机性以及认识论随机性,进而给出了第四种也即符号学式的定义。随机性不来自内在的本体论特征,也不是因为我们不具备完全的感知力,因此它是底层规则性在现象学意义上的不可测性。它的产生也不是因为它不与那些似乎可以被掌握甚至被控制的准则不相符。随机性是通过制造可以描述以及理解不规则性的元语言而形成的。为了说明上述定义,本文重构皮尔斯符号过程这一概念,区分解释项与解释范围之间的差异,并阐明过度复杂化、过度简化以及意义等概念。本文最后指出,不同领域的学者应当在将来致力于探索一个正确的范围,在这种范围中对实在的理解必然会发生,同时探索对实在的理解作为一种结果所需的社会协调和行动程度。

Chronic kidney disease and its worsening are recurring conditions in chronic heart failure(CHF) which are independently associated with poor patient *** heart and kidney share many pathophysiological mechanisms which can determine dysfunction in each organ. Cardiorenal syndrome is the condition in which these two organs negatively affect each other, therefore an accurate evaluation of renal function in the clinical setting of CHF is essential. This review aims to revise the parameters currently used to evaluate renal dysfunction in CHF with particular reference to the usefulness and the limitations of biomarkers in evaluating glomerular dysfunction and tubular damage. Moreover, it is reported the possible utility of renal arterial resistance index(a parameter associated with abnormalities in renal vascular bed) for a better assesment of kidney disfunction.

BACKGROUND Few studies have examined intestinal motility disorders, which are disabling conditions associated with chronic functional constipation, whose pathogenesis is actually not *** To investigate the relationship between serum 25-hydroxyvitamin D levels and functional chronic constipation associated to intestinal motility *** We performed a prospective case-control study, from May-June to November2017. Glucose/lactulose breath tests, radiopaque markers(multiple capsule techniques) and wireless motility capsule analysis were used to assess colonicand oro-cecal transit time, after excluding small-intestinal bacterial overgrowth condition. Then, we measured 25-hydroxyvitamin D levels in patients with intestinal motility disorders and we further evaluated the influence of intestinal motility disorders on psychological symptoms/quality of life using validated questionnaires, the Irritable Bowel Syndrome Quality of life(IBS-QOL), the Short Form Health Survey 12, and the Hospital Anxiety and Depression Scale 14(HADS-14 A and HADS-14 D).RESULTS We enrolled 86 patients with chronic functional constipation associated to intestinal motility disorders and 86 matched healthy subjects. Patients with intestinal motility disorders had lower 25-hydroxyvitamin D levels(P < 0.001), and they showed a significant impairment of all health-related quality of life and psychological tests(IBS-QOL, Short Form Health Survey 12-Physical Component Summary, Short Form Health Survey 12-Mental Component Summary, HADS-14 A and HADS-14 D), as compared to the control group(P < 0.001), which significantly correlated with low vitamin D levels(r =-0.57, P < 0.001; r = 0.21, P = 0.01; r =-0.48, P < 0.001; r =-0.57, P < 0.001; r =-0.29, P < 0.001, respectively). At multivariate analysis vitamin D low levels remained a significant independent risk factor for the occurrence of intestinal motility disorder(odds ratio = 1.19; 95% confidence interval: 1.14-1.26, P < 0.001).CONC

Ventricular repolarization is a complex electrical phenomenon which represents a crucial stage in electrical cardiac activity. It is expressed on the surface electrocardiogram by the interval between the start of the QRS complex and the end of the T wave or U wave(QT). Several physiological, pathological and iatrogenic factors can influence ventricular repolarization. It has been demonstrated that small perturbations in this process can be a potential trigger of malignant arrhythmias, therefore the analysis of ventricular repolarization represents an interesting tool to implement risk stratification of arrhythmic events in different clinical settings. The aim of this review is to critically revise the traditional methods of static analysis of ventricular repolarization as well as those for dynamic evaluation, their prognostic significance and the possible application in daily clinical practice.

Single-photon entanglement is a peculiar type of entanglement in which two or more degrees of freedom of a single photon are correlated quantum-mechanically. Here, we demonstrate a photonic integrated chip able to generate and manipulate single-photon path-entangled states, using a commercial red LED as light source.A Bell test, in the Clauser, Horne, Shimony, and Holt(CHSH) form, is performed to confirm the presence of entanglement, resulting in a maximum value of the CHSH correlation parameter equal to 2.605 ± *** allows us to use it as an integrated semi-device independent quantum random number generator able to produce certified random numbers. The certification scheme is based on a Bell’s inequality violation and on a partial characterization of the experimental setup, without the need of introducing any further assumptions either on the input state or on the particular form of the measurement observables. In the end a min-entropy of 33% is demonstrated.
