Abstract
Vergil interweaves the varying meanings of
amor
, from not only a positive force, to aggressive desires and to all its varied aspects, making it both harsh, deceptive and cruel, and ...conversely something very special reflecting things most cherished and respected.
The article considers a significant aspect of Strada per Roma, namely the narcissistic personality of the main protagonist, the young Guido Corsalini, and the sensual valence of Paolo Volponi's early ...poetic production written at the same time of this novel. To this end, the essay traces, also in the light of analytical doctrines on the subject, but not only, Guido's inner journey, focusing on those episodes that highlight an Ego of the character that has remained emotionally stuck at an infantile age. Indeed, it will be the experience of intimacy with Barnaba, the separation from his childhood friend Ettore, that will mentally project Guido into a different, more adult and conscious mental atmosphere, on the streets of Roma.
A partir de la revisión de la antología El canon abierto. Última poesía en español el presente artículo plantea que una importante parte de la poesía en lengua española circunda el tema de la ...construcción de la imagen. Esto lo hace a partir de la melancolía y de la estética barroca que fungen como dos características canónica de la cultura iberoamericana. En el trabajo se observa que pese a las diferentes corrientes estéticas de dicha poesía existe una tendencia natural hacia la recreación de imágenes inspiradas o generadas por el estado melancólico.
In order to understand the geological evolution of asteroids Eros, Itokawa and Ryugu and their collisional history, previous studies investigated boulder size distributions on their surfaces. ...However, quantitative comparison of these size distributions is hampered by numerous differences between these studies regarding the definition of a boulder's size, measuring technique and the fitting method to determine the power-index of the boulder size distributions. We provide a consistent and coherent model of boulder size distributions by remeasuring the boulders on the entire surfaces of Eros and Itokawa using the Small Body Mapping Tool (SBMT) and combining our observations with the Ryugu data of Michikami et al. (2019). We derived power-indices of the boulder size distributions of −3.25 ± 0.14 for Eros, −3.05 ± 0.14 for Itokawa and −2.65 ± 0.05 for Ryugu. The asteroid with the highest number density of boulders ≥ 5 m turns out to be Ryugu, not Itokawa, as suggested by an earlier study. We show that the appearance of the boulders tends towards more elongated shapes as the size of an asteroid decreases, which can be explained by differences in asteroid gravity and boulder friction angles. Our quantitative observational results indicate that boulder migration preferentially affects smaller boulders, and tends to occur on larger asteroids.
•First comparative survey free from observer bias of boulders on Eros, Itokawa and Ryugu.•Boulders appear to be more elongated as the size of an asteroid decreases.•Boulder migration preferentially affects smaller boulders and larger asteroids.
Resumo Inspirado por Martha Nussbaum e tomando como referência a ideia formativa inerente à ascese amorosa, o artigo investiga o significado atribuído a Eros por Platão em O banquete. Primeiro, ...reconstruímos o discurso de Aristófanes, enfatizando o aspecto de dupla comédia da vida humana. Depois, analisamos o caráter formativo do discurso de Diotima em termos de um duplo ensinamento: o da sacerdotisa a Sócrates e o de Sócrates a nós. Em seguida, indicamos o quanto a dialética do amor, ao ter que responder à objeção de Alcibíades, conduz à mudança da postura de Sócrates à medida que a presença de Alcibíades o faz retornar ao mundo sensível. Por fim, destacamos a dimensão formativa da ascese do amor e da reversibilidade de papéis entre erasta e erômeno, amante e amado.
Abstract Inspired by Martha Nussbaum and taking as its guideline the discussion on the formative idea inherent to the askesis of love, this paper investigates the meaning Plato attributes to Eros in the Symposium. First part reconstructs the speech from Aristophanes, emphasizing the double comedy of the human life. The second part summarizes the formative aspect of Diotima’s speech from the perspective of a double lesson: from the priestess to Socrates, and from him to ourselves. The third part tries to point out how much the dialectic of love, by having to respond to Alcibiades’ objection, is what leads to the change on Socrates’ posture, insofar as the presence of Alcibiades makes him to back into the sensible. Finally, the formative dimension of the askesis of love is highlighted, stressing how much it leads to the reversibility of roles between erasta and eromeno, between lover and beloved.
Impact-induced seismic vibrations have long been suspected of being an important surface modification process on small satellites and asteroids. In this study, we use a series of linked seismic and ...geomorphic models to investigate the process in detail. We begin by developing a basic theory for the propagation of seismic energy in a highly fractured asteroid, and we use this theory to model the global vibrations experienced on the surface of an asteroid following an impact. These synthetic seismograms are then applied to a model of regolith resting on a slope, and the resulting downslope motion is computed for a full range of impactor sizes. Next, this computed downslope regolith flow is used in a morphological model of impact crater degradation and erasure, showing how topographic erosion accumulates as a function of time and the number of impacts. Finally, these results are applied in a stochastic cratering model for the surface of an Eros-like body (same volume and surface area as the asteroid), with craters formed by impacts and then erased by the effects of superposing craters, ejecta coverage, and seismic shakedown. This simulation shows good agreement with the observed 433 Eros cratering record at a Main Belt exposure age of
400
±

Myr
, including the observed paucity of small craters. The lowered equilibrium numbers (loss rate
=
production rate) for craters less than ∼100 m in diameter is a direct result of seismic erasure, which requires less than a meter of mobilized regolith to reproduce the NEAR observations. This study also points to an upper limit on asteroid size for experiencing global, surface-modifying, seismic effects from individual impacts of about 70–100 km (depending upon asteroid seismic properties). Larger asteroids will experience only localized (regional) seismic effects from individual impacts.
Cerebrospinal and structural‐molecular neuroimaging in‐vivo biomarkers are recommended for diagnostic purposes in Alzheimer’s disease (AD) and other dementias; however, they do not explain the ...effects of AD neuropathology on neurophysiological mechanisms underpinning cognitive processes. Here, an Expert Panel from the Electrophysiology Professional Interest Area of the Alzheimer’s Association reviewed the field literature and reached consensus on the event‐related electroencephalographic oscillations (EROs) that show consistent abnormalities in patients with significant cognitive deficits due to Alzheimer’s, Parkinson’s (PD), Lewy body (LBD), and cerebrovascular diseases. Converging evidence from oddball paradigms showed that, as compared to cognitively unimpaired (CU) older adults, AD patients had lower amplitude in widespread delta (>4 Hz) and theta (4–7 Hz) phase‐locked EROs as a function of disease severity. Similar effects were also observed in PD, LBD, and/or cerebrovascular cognitive impairment patients. Non‐phase‐locked alpha (8–12 Hz) and beta (13–30 Hz) oscillations were abnormally reduced (event‐related desynchronization, ERD) in AD patients relative to CU. However, studies on patients with other dementias remain lacking. Delta and theta phase‐locked EROs during oddball tasks may be useful neurophysiological biomarkers of cognitive systems at work in heuristic and intervention clinical trials performed in AD patients, but more research is needed regarding their potential role for other dementias.
A multidisciplinary Expert Panel reviewed the literature and reached a consensus on the event‐related electroencephalographic oscillations (EROs) showing consistent abnormalities in patients with significant cognitive deficits due to Alzheimer’s, Parkinson’s (PD), Lewy body (LBD), and cerebrovascular diseases. Delta and theta phase‐locked EROs during oddball tasks may be useful as neurophysiological biomarkers of cognitive systems at work in AD patients, although those EEG measures were unspecific in relation to the other dementing disorders mentioned above.
Chronic Granulomatous Disease (CGD) is an inborn error of immunity characterised by opportunistic infection and sterile granulomatous inflammation. CGD is caused by a failure of reactive oxygen ...species (ROS) production by the phagocyte NADPH oxidase. Mutations in the genes encoding phagocyte NADPH oxidase subunits cause CGD. We and others have described a novel form of CGD (CGD5) secondary to lack of EROS (CYBC1), a highly selective chaperone for gp91phox. EROS-deficient cells express minimal levels of gp91phox and its binding partner p22phox, but EROS also controls the expression of other proteins such as P2X7. The full nature of CGD5 is currently unknown. We describe a homozygous frameshift mutation in CYBC1 leading to CGD. Individuals who are heterozygous for this mutation are found in South Asian populations (allele frequency = 0.00006545), thus it is not a private mutation. Therefore, it is likely to be the underlying cause of other cases of CGD.
