Novel Dialogue 2.3: Because I Couldn't Be a Dancer: Sigrid Nunez and Tara Menon (JP)
No full textThe brilliant New York writer Sigrid Nunez's most recent novel is What Are You Going Through; her previous one, The Friend, (2018) won the National Book Award. She speaks with Tara Menon, of the Harvard English department, and author of a terrific article about Sigrid Nunez in the Sewanee Review. The conversation ranges widely and then plunges into depths. Because life is defined by grief and mourning, so too are my novels, says Nunez. She thinks her upbringing with immigrant parents who felt adrift from their homeland and her own "failure" as a dancer (recounted in her 1995 debut novel, A Feather on the Breath of God ) are the ferment from which her vocation as a writer arose. The question of genre is tossed around: "fictional memoir" perhaps, which gets confused (insultingly, Tara thinks!) with auto-fiction. But Sigrid is fascinated by establishing a reality that is entirely made-up ("not a single friend angry!"), yet also documentary in nature. Perhaps the best tag for her work is "essay novel": that allows one to do what Javier Marias calls "literary thinking." And there's a wonderfully non-Pavlovian answer to the treat question: sometimes you can just have the whiskey
Long working distance high resolution reflective sample imaging via structured embedded speckle illumination
No full textImaging beyond the diffraction limit at longer working distances using enhanced microscopic configurations has always been a challenge for biological and engineering samples. Even though multiple techniques have been widely used for sub-diffraction limit resolution imaging, the achievable resolution was relying on the use of objective lenses with a high numerical aperture (NA). In the case of engineering samples, in addition to sustaining higher resolutions at large working distances, improving the signal-to-noise ratio (SNR) is also critical. In this context, we propose and demonstrate a concept for high-resolution imaging at large working distances, termed as structured illumination embedded speckle microscopy. An imaging resolution of ~ 310 ± 5 nm was achieved with a microscope objective (0.55 NA; 50X) having 11 mm long working distance using a Siemen's star as the test sample. The demonstrated microscopy is therefore envisaged for engineering applications that demands high-resolution, high SNR imaging at long working distances
A priori and a posteriori analysis of the hybrid two-level large-eddy simulation method for high Reynolds number complex flows
No full textWe present a priori and a posteriori analysis of the assumptions and predictions of the hybrid two-level large-eddy simulation (TLS-LES) method for high Reynolds number complex flows. The TLS-LES methodology is a multi-scale framework for simulation of turbulent flows in complex configurations at practically relevant Reynolds number. It additively combines the two-level simulation (TLS) model with a conventional large-eddy simulation (LES) approach by employing a static or dynamic blending function. In the present study, first we analyze the model assumptions employed by the TLS model to obtain the small-scale solution necessary for closure of the large-scale equations. Afterward, we analyze the large-scale and small-scale solutions to assess the predictive ability of the multi-scale framework for specific turbulence physics such as role of forward and backscatter of energy and presence of co- and counter-gradient diffusion. To perform these investigations, we consider cases with increasing degree of geometrical complexity, namely, flow in a periodic channel, flow past a bump placed on the lower surface of the channel and flow past a finite-span NACA0015 airfoil
Il bene del filosofo e il limite della città. Sulla politica filosofica di Leo Strauss
No full textThe intention of this paper is to show how Leo Straussʼ mature writings respond to the twofold necessity of political philosophy: contributing, at the same time, to the good of the city and to the good of the philosophers. In the first place, it will try to prove this point by analyzing in detail the Introduction to On Tyranny (1948), which represents an essential step in order to understand the intention of the author. In the second place, it will tackle the problem of justice, that is, of natural right, by concentrating on the so called " tyrannical teaching ". This teaching is a way to present a truth which the city cannot find acceptable, that is, an unpleasant truth concerning the irresoluble problem of justice and legitimacy. In conclusion, it will point to the tension between philosophy, i.e., search for knowledge, and the city, i.e., the realm of opinion. For the philosopher, as such, has to " corrupt " the young in order to pursue his search for knowledge of the whole, or the nature of all things. Therefore, he weakens the city, since philosophizing implies unbelief in the gods of the city
Equivariant elliptic cohomology and twisted equivariant k-theory
No full textEquivariant elliptic cohomology and twisted equivariant K-theory are both related to the representations of loop groups. After making these relationships precise, we propose a map from twisted equivariant elliptic cohomology to twisted K-theory of the inertia stack using equivariant de Rham models. This proposal agrees with the Freed-Hopkins-Teleman q = 1 map from characters of representations of loop groups to distributions associated to twisted equivariant K-theory classes.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Dileep Menon, accepted the attached license on 2019-05-24 at 15:54.The student, Dileep Menon, submitted this Dissertation for approval on 2019-05-24 at 16:06.This Dissertation was approved for publication on 2019-05-28 at 10:50.DSpace SAF Submission Ingestion Package generated from Vireo submission #13991 on 2019-11-26 at 13:00:58Made available in DSpace on 2019-11-26T20:49:00Z (GMT).

Breaking diffraction limit of far-field imaging via structured illumination Bessel beam microscope (SIBM)
No full textBreaking the diffraction limit in imaging microscopes with far-field imaging options has always been the thrust challenge for optical engineers and biologists over the years. Although structured illumination microscopy and Bessel beam assisted imaging has shown the capability of imaging with sub-diffraction resolutions, they rely on the use of objective lenses with large numerical apertures (NA). Hence, they fail to sustain resolutions at larger working distances. In this context, we demonstrate a method for nanoscale resolution imaging at longer working distances, named as Structured Illumination Bessel Microscopy (SIBM). The proposed method is envisaged for both biological and engineering applications that necessitate high imaging resolutions at large working distances.</p

God on the hill and other stories
No full textWhat makes this book poignant and relevant is the counterpoint to archaeological narratives it posits. Though archaeologists tell us that these megalithic dolmens, menhirs and the like were funerary or commemorative structures, local villagers near the monuments insist that they were the houses of a now-extinct race of dwarves called Moriyas. The stories in this collection are inspired by actual monuments and sites in India. As architect-author Srikumar M Menon went along collecting data about the monuments, he could not help collecting stories too. Srikumar’s stories also draw attention to outdated theories on the development of disciplines such as the ‘history of architecture’. Legislation and barbed wire fencing are grossly inadequate to protect these primitive monuments that our prehistoric ancestors built
The development of herbert rosenfeld's views on narcissism
No full textThis review tracks the development of Herbert Rosenfeld's (1910–1986) work on the psychoanalytic concept, narcissism. The author conceptualizes the scope of this work in Darwinian terms to emphasize the extraordinarily fertile theoretical and clinical material produced by Rosenfeld, which is linked in the text to several other contemporary Kleinian psychoanalysts. The beginning of his lifelong work is examined as “Origins,” the development itself as “Evolution” and at the end of his life, the shifts in his theoretical stance is looked at as “Metamorphosis.” Clinical material is used to illustrate the core concept of narcissism as a defence against separateness
