Ontology of Diasporic Emotions in If You See Me, Don't Say Hi by Neel Patel
No full textIn If You See Me, Don’t Say Hi (2018), the Indian American author and screenwriter Neel Patel charts the tensions and conflicts of Indian American citizens, mainly from a queer perspective. Patel’s eleven short stories explore human relationships and emotions, with a special focus on such themes as love, friendship, family ties, sexuality and betrayal. The protagonists of the stories are diasporic subjects who recall the myth of the model minority as they struggle to piece their lives together, while striving to achieve professional success by assimilating into mainstream American culture. Starting from these premises, this essay looks at Patel’s stories as narratives where anger, dissatisfaction, melancholia, disorientation, and grief prevail. First, it shows how emotions, understood as “structures of feeling,” shape the South Asian diasporic imaginary. Then, it explores the ways diasporic subjects are immersed in a condition of racial melancholia that characterises the narrative of the model minority. Finally, it discusses how queer grief intensifies this sense of loss, thus laying emphasis on the pedagogic function of negative emotions
On Sparsification of Stochastic Packing Problems
No full textMotivated by recent progress on stochastic matching with few queries, we embark on a systematic study of the sparsification of stochastic packing problems more generally. Specifically, we consider packing problems where elements are independently active with a given probability p, and ask whether one can (non-adaptively) compute a "sparse" set of elements guaranteed to contain an approximately optimal solution to the realized (active) subproblem. We seek structural and algorithmic results of broad applicability to such problems. Our focus is on computing sparse sets containing on the order of d feasible solutions to the packing problem, where d is linear or at most polynomial in 1/p. Crucially, we require d to be independent of the number of elements, or any parameter related to the "size" of the packing problem. We refer to d as the "degree" of the sparsifier, as is consistent with graph theoretic degree in the special case of matching.
First, we exhibit a generic sparsifier of degree 1/p based on contention resolution. This sparsifier’s approximation ratio matches the best contention resolution scheme (CRS) for any packing problem for additive objectives, and approximately matches the best monotone CRS for submodular objectives. Second, we embark on outperforming this generic sparsifier for additive optimization over matroids and their intersections, as well as weighted matching. These improved sparsifiers feature different algorithmic and analytic approaches, and have degree linear in 1/p. In the case of a single matroid, our sparsifier tends to the optimal solution. In the case of weighted matching, we combine our contention-resolution-based sparsifier with technical approaches of prior work to improve the state of the art ratio from 0.501 to 0.536. Third, we examine packing problems with submodular objectives. We show that even the simplest such problems do not admit sparsifiers approaching optimality. We then outperform our generic sparsifier for some special cases with submodular objectives
Antiferromagnetic resonance in a-Fe2O3 up to its Neel temperature
No full textHematite (alpha-Fe2O3) is an antiferromagnetic material with a very low spin damping and high Neel temperature. The temperature dependence of the antiferromagnetic resonance in a bulk single crystal of hematite was characterized from room temperature up to the Neel temperature in the frequency range of 0.19-0.5 THz. From these data, the Neel temperature was estimated as 966 K. (C0 2022 Author(s).LPM
Comparison of investigator-delineated gross tumour volumes and quality assurance in pancreatic cancer: analysis of the on-trial cases for the SCALOP trial
No full textBackground and purpose: we performed a retrospective central review of tumour outlines in patients undergoing radiotherapy in the SCALOP trial.Materials and methods: the planning CT scans were reviewed retrospectively by a central review team, and the accuracy of investigators’ GTV (iGTV) and PTV (iPTV) was compared to the trials team-defined gold standard (gsGTV and gsPTV) using the Jaccard Conformity Index (JCI) and Geographical Miss Index (GMI). The prognostic value of JCI and GMI was also assessed. The RT plans were also reviewed against protocol-defined constraints.Results: 60 patients with diagnostic-quality planning scans were included. The median whole volume JCI for GTV was 0.64 (IQR: 0.43–0.82), and the median GMI was 0.11 (IQR: 0.05–0.22). For PTVs, the median JCI and GMI were 0.80 (IQR: 0.71–0.88) and 0.04 (IQR: 0.02–0.12) respectively. Tumour was completely missed in 1 patient, and ⩾ 50% of the tumour was missed in 3. Patients with JCI for GTV ⩾ 0.7 had 7.12 (95% CIs: 1.83–27.67, p = 0.005) higher odds of progressing by 9 months in multivariate analysis. Major deviations in RT planning were noted in 4.5% of cases.Conclusions: radiotherapy workshops and real-time central review of contours are required in RT trials of pancreatic cancer
Rigidity of acute angled corners for one phase Muskat interfaces
No full textWe consider the one-phase Muskat problem modeling the dynamics of the free boundary of a single fluid in porous media. In the stable regime, we prove local well-posedness for fluid interfaces that are general curves and can have singularities. In particular, the free boundary can have acute angle corners or cusps. Moreover, we show that isolated corners/cusps on the interface must be rigid, meaning the angle of the corner is preserved for a finite time, there is no rotation at the tip, the particle at the tip remains at the tip and the velocity of that particle at the tip points vertically downward.We are very grateful to Inwon Kim for explaining to us the equivalence of the one phase Muskat equation and the Hele Shaw problem with injection at infinity in an infinite domain.
